    PUMP FOR HAIR REMOVAL DEVICE WITH LIQUID DISPENSATION
    FIELD OF THE INVENTION
    The present invention relates to hair removal devices in general, and, more particularly, to hair removal devices that have mechanisms for providing one or more shaving or waxing flowable materials.
    BACKGROUND OF THE INVENTION
    Skin treatment can be of particular importance in enhancing or accentuating the appearance of men and women. Various products and methods can be used to treat the skin. For example, exfoliating sponges, cleansers and lotions are sometimes used to keep skin looking healthy. Exfoliating sponges can be used to remove dead skin cells from the skin's surface, which can give the skin an enhanced tone. Soaps and other skin cleansers to remove dirt and excess oil from the skin can be used, which can help prevent pore clogging. Consequently, acne and other types of skin imperfections can be prevented in some cases. Lotions and various other topical ointments can also be used to provide nutrients and / or moisturizers to the skin in an attempt to improve the appearance and / or health of the skin. Other types of cosmetic products (for example, creams and lotions) or pharmacological actives are sometimes used in an attempt to eliminate wrinkles and other signs of aging.
    It is common knowledge that the shaving or epilation process of the skin can provide certain
    2/51 skin benefits such as exfoliation and hydration. In general, wet shavers or shavers include a cartridge or blade unit with at least one blade with a sharp edge that is moved along the surface of the skin to be shaved or shaved using a cable to which the cartridge is attached; However, razor or epilator sets may also include electric foil razors or epilators. The cartridge can be removably mounted on the handle to allow the cartridge to be replaced with a new cartridge when the blade efficiency reaches an unsatisfactory level, or that the cartridge can be permanently attached to the handle with the intention that the entire shaving or shaving is discarded when the razor or blades lose their edge (ie disposable razor or shaving). The connection of the cartridge to the handle provides a pivoting assembly of the cartridge in relation to the handle, so that the angle of the cartridge adjusts to follow the contours of the surface being shaved or shaved. In such systems, the cartridge can be tilted to a rest position by the action of a spring activated plunger (a meat follower) loaded on the handle against a meat surface in the cartridge compartment.
    shaving or shaving process typically includes applying a shaving or shaving aid material (eg shaving cream) to the surface and the separate step of shaving or shaving the hair using a shaving or shaving set. Shaving or waxing aids often include at least one agent
    3/51 suitable (for example, a lubricating agent, a drag reducing agent, a depilatory agent, etc.) that improves the shaving or waxing process. Most consumers find this type of preparation quite inconvenient due to the need for various products for shaving or epilation, for example, a razor or epilator for shaving or wet epilation and a skin preparation product, as well as the unwanted need for several application steps during shaving or wet hair removal. In addition, this process can be complicated and require the consumer to wash their hands after applying shaving or shaving gel. This multi-step process also results in an extensive shaving or waxing experience in general, which most consumers do not appreciate given the typical morning hygiene routines. However, it may sometimes be desirable to apply fluids of other types to the skin before, during or after shaving or waxing. It has been found that, especially in the case of male individuals, who shave facial hair, it is important to provide a preparation for shaving or waxing of some kind before shaving in order to properly hydrate thicker facial hair to allow a shaving or a closer and easier shaving.
    In the past, there were numerous shaving or wet shaving product configurations that included a system for conveying a shaving or waxing preparation during shaving, for example, a lubricating liquid, from a reservoir built into the shaver frame. in the form of a cable from the
    4/51 hollow shaver or even an aerosol can that acts as a shaver or shaver handle to a dispensing location near the head of the shaver or shaver. Numerous newer razors or shavers for shaving or wet hair removal have cartridges that are movably mounted, in particular pivotable, in relation to the cable structures on which they are permanently mounted, in the case of disposable safety shavers intended for disposal when the blade or blades lose their edge, or to allow removably replacing the blade unit in a reusable cable frame. Many of these types of razors or shavers that are able to carry a liquid to the skin's surface are unfortunately affected by numerous problems. For example, the internal parts of shavers or shavers are complicated and tend to be cost prohibitive from the point of view of large-scale manufacturing. In addition, there are safety and performance issues that are constantly experienced due to microbial growth inside the reservoir due to continuous exposure of a portion of the remaining liquid to the air. This exposure of the liquid to the air can often result in the obstruction of the internal parts of the razor or hair removal by the liquid resulting in a shaving or hair removal product that has failed execution.
    Hair removal process is known to cause certain irritations and discomfort to the skin. Accordingly, desirable skin benefits may include smoothness and hydration. Softness and hydration are not typically achieved by a razor or shaver.
    5/51 shave itself, but with a lotion or cream that is applied to the skin after shaving or shaving and after the shaving or shaving gel has been removed from the skin. Regardless of whether the hair removal process is wet or dry shaving or epilation, there is an ongoing need to provide certain personal care compositions to accompany or facilitate the hair removal process. Typically, the personal care composition is commercially available as a separate package.
    SUMMARY OF THE INVENTION

    DETAILED DESCRIPTION OF THE INVENTION
    This description is not limited to razors or wet hair removal, or even razors or hair removal in general. It is understood that certain aspects of the present description can also be used for dry electric shavers or shavers that have one or more rotating or reciprocating blades or other personal care applications (for example, toothbrushes, depilatory applicators, epilators, or other beauty applicators). In addition, it is understood that certain aspects of the present description can be used regardless of the application of a liquid (for example, a cartridge and a dispensing unit 150 can be used independently).
    The present description is not limited to shaving or shaving cartridges in which the blades are rigidly mounted in a fixed position in relation to the shield and / or a cover. If the blades are capable of movement then the geometric parameters stipulated here are those
    8/51 apply when the blades are in their normal resting positions. Each of the blade units of the safety razor or shaver illustrated is intended to be mounted on a razor or shaver handle. The blade unit may be permanently attached to the handle, for example, in a disposable razor or shaver, or it may be formed as a cartridge adapted to be releasably mounted to the handle. The blade unit can be mounted pivotally to the handle or can be fixedly attached to the handle.
    One or more blades can be mounted in a housing. The term assembled a can be defined as any of the following described herein. The cutting blade can be supported firmly by the housing to remain substantially fixed in the positions in which they are described (subject to any resilient deformation that the blades are subjected to by forces applied against the blades during shaving or waxing). Alternatively, the blades can be supported for limited movements against spring restoring forces, for example, in a downward direction as seen in the drawings. The basic construction and assembly of the blade units can be conventional.
    Referring to Figures 1A and 1B, a possible embodiment of the present description is shown illustrating a side view and a top view (respectively) of a hair removal device 10 with a hair removal cartridge 12 mounted on cable 50. The device Hair removal 10 can include, but is not limited to, razors or shavers, depilatory applicators, and epilators. In certain
    9/51 modalities, the cable 50 can be molded from a semi-rigid material, such as high impact polystyrene. Cable 50 can be molded from other semi-rigid polymers that have a Shore D hardness of about 60 to 140, including, but not limited to, Noryl ™ (a blend of polyphenylene oxide (PPO) and polystyrene developed with General Electric Plastics, currently SABIC Innovative Plastics), acrylonitrile-butadiene-styrene (ABS), acetal, polypropylene, high-impact polystyrene, or any combination thereof. In certain embodiments, the cable 50 may comprise metal (for example, the cable 50 may be metal fused to the matrix or have metal inserts to increase the weight of the cable 50).
    As will be explained in more detail below, the cartridge 12 can be pivotable (i.e., the rotation of the cartridge 12 about an axis with respect to the cable 50 and / or removably engaged with the cable 50). It should be understood that certain embodiments may include cartridges 12 that articulate in relation to the handle 50, but are also permanently attached to the handle 50 (i.e., razors or disposable epilators). Disposable razors or shavers can have an articulated or non-articulated cartridge 12. The cable 50 can have a body 52 and a neck 54. The body 52 of the cable 50 can provide an area for the user to comfortably grip the hair removal device 10. The neck 54 can have a generally V-shaped geometry with a pair of opposite arms 56a and 56b extending from the body 52 and engaging the cartridge 12. As will be explained in more detail below, the device removal unit 10 can have a removable dispensing unit (not shown) at the
    10/51 less partially arranged inside the cable 50. The dispensing unit 150 can have an applicator 100 that supports the cartridge 12 and flexes as the cartridge 12 articulates in relation to the cable 50. In certain embodiments, the cartridge 12 can be pulled to a rest position by the action of applicator 100 (for example, applicator 100 applies a changing force against cartridge 12 during a shaving or waxing course). A cap 60 can be mounted to the cable 50 to secure the dispensing unit inside the cable 50. The cable 50 and / or cap 60 can have an actuator 62 disposed on an external surface 64 to facilitate the dispensing of liquid from the control unit. dispensation. A removable personal care bottle 250 containing a second liquid can be mounted on one end of the handle 50. The hair removal device 10 can provide multiple benefits to the skin without the need to purchase any cleansing creams, lotions, and / or creams additional. The hair removal device 10 can dispense a first liquid during shaving or epilation on or near the cartridge 12. The hair removal device 10 can also contain a second liquid which can be dispensed independently of the first liquid. The first and second liquids can be the same or different.
    Referring to figures 2A and 2B, a top view of the hair removal device 10 of figure 1 is shown and a cross-sectional view of cable 50, taken in general along line 2B-2B of figure 2A are illustrated. The hair removal device 10 can be a set that includes a plurality of consumer products that can be purchased separately by the consumer.
    11/51
    For example, in certain embodiments, the consumer may purchase cartridge 12, personal care bottle 250 separately, and / or a dispensing unit 150 separately. In certain embodiments, reservoir 220 may also be purchased separately and attached to pump 160 by consumer. As will be explained in more detail below, the dispensing unit 150 can include applicator 100, a pump 160 in fluid communication with applicator 100, and a reservoir 220 in fluid communication with pump 160. Reservoir 220 can contain a or more liquids that may be useful in the present hair removal device 10. For example, shaving or hair removal gels, shaving or hair removal foams, shaving or hair removal lotions, skin care compositions, conditioning aids, depilatories, etc. . can be used to prepare the skin or hair surface before and during shaving or waxing.
    Air can be removed from reservoir 220 with a vacuum, and then reservoir 220 can be filled and pressurized with liquid to provide an airless system. Full reservoir 220 can effectively use more space than a rigid bottle, but it also provides sufficient rigidity so that the consumer can easily load reservoir 220 into cable 50. In addition, loading reservoir 220 onto cable 50 can compress reservoir 220 so that when dispensing unit 150 is activated, pump 160 is partially filled with liquid to reduce the need for priming of pump 160.
    In certain embodiments, reservoir 220 can be a flexible laminated bag to provide performance
    12/51 barrier (for example, water resistance and oxygen loss). Reservoir 220 may comprise a barrier layer of foil (e.g. aluminum) between an inner layer of polyethylene and an outer layer of polyethylene terephthalate (PET). Alternatively, the inner and / or outer layer can be metallized (for example, a polymeric film containing or coated with metal particles). For example, reservoir 220 may comprise an inner layer of a metallized polyethylene film having a thickness of about 30 µm, 40 µm, or 50 µm to about 70 µm, 80 µm, or 90 µm. The inner layer can be laminated to an outer layer of PET film with a thickness of about 6 µm, 7 µm, or 8 µm to about 10 µm, 11 µm, or 12 µm. The inner layer and the outer layer can be laminated together during an extrusion process or an adhesive can be used to seal the two layers together. Reservoir 220 can be heat sealed to a semi-rigid reservoir connector 164. The outer layer of PET may have a higher melting temperature than the inner layer of polyethylene. Consequently, the inner layer seals tightly to the reservoir connector 164 (for example, providing a liquid impermeable seal) and the outer layer may not melt to maintain the integrity of the reservoir 220.
    Over time, water and other chemicals have a tendency to permeate through films that can have detrimental consequences on the chemistry and performance of the liquid formulation contained within reservoir 220. The flexibility of reservoir 220 allows reservoir 220 to be deformable to an
    13/51 maximum utilization of space inside the cable 50. Barrier properties can be achieved by increasing the thickness of the material of the reservoir 220, thus making the reservoir less flexible. A metallized polymer film, such as polyethylene, can provide superior barrier properties to prevent unwanted passage of water and oxygen into or out of reservoir 220 without sacrificing flexibility. In certain embodiments, the overall wall thickness of the reservoir 220 can be about 36 µm, 46 µm, or 56 µm to about 70 µm, 80 µm, or 101 µm.
    In certain embodiments, pump 160 and applicator 100 may not be in fluid communication with reservoir 220 until dispensing unit 150 is activated (for example, mounted inside cable 50 and / or cap 60 is attached to the cable 50). The dispensing unit 150 can have a first connector (for example, pump connector 162) and a second connector (for example, reservoir connector 164) that are in fluid communication with pump 160. The reservoir 220 (for example , the inner layer of polyethylene) can be heat sealed around reservoir connector 164. As will be explained in more detail below, pump connector 162 and reservoir connector 164 can be moved from a first position (for example, closed position) to a second position (for example, activated position). In the first position, pump 160 and applicator 100 may not be in fluid communication with reservoir 220. In the second position, pump 160 and applicator 100 may be in fluid communication with reservoir 220, allowing,
    14/51 thus, that the liquid contained inside the reservoir 220 is dispensed.
    The cable 50 can define a first cavity 70 sized to receive at least a portion of a dispensing unit 150. For example, the reservoir 220 can be completely fitted inside the cable 50 and / or cap 60, but the applicator 100 may not completely attached by cable 50 and / or cap 60. Applicator 100 can be removably attached to the
    inside of a recess 14 of the cartridge 12. 0 applicator 100 can have a or more elements in alignment 102 and 104 in order to facilitate The positioning correct from unity in dispensing 150 and / or applicator 100 at the inland of the cable 50. If the unit in dispensation 150 don't go oriented properly in cable inside 50, a unity in
    dispensing 150 may become damaged or may not release liquid from reservoir 220 properly. The alignment elements 102 and 104 can be spaced apart from the recesses and / or projections that are of a different size, shape, orientation, or any combination thereof. The cable 50 may have one or more corresponding alignment elements 82 and 84 that are sized to receive the one or more alignment elements 102 and 104 from the applicator 100. The alignment elements 82 and 84 of the cable 50 and the alignment elements 102 and 104 of applicator 100 can ensure that applicator 100 is properly located within the recess 14 of the cartridge 12.
    cable 50 may have a pair of spaced walls 72 and 74 within the first cavity 70. At least one pair of spaced walls 72 and 74 may have
    15/51 a conical surface 75 (as shown in figure 2B) inclined to the spaced opposite walls 72 and 74 to facilitate the actuation of the pump connector 162 and the reservoir connector 164 and thus provide the liquid communication from the reservoir 220 to the applicator 100. In certain embodiments, wall 72 can be vertical and tapered surface 75 can be positioned on wall 74 which is in contact with reservoir connector 164 to prevent pump 160 and / or applicator 100 from moving or stretching as the dispensing unit 150 is activated (i.e. it moves from the first position to the second position). The conical surface 75 of the wall 74 can have an inclination of about 20 degrees, 22 degrees, or 24 degrees to about 26 degrees, 28 degrees, or 30 degrees with respect to the opposite wall 72. The conical surface 75 can facilitate the connector pump 162 and / or reservoir connector 164 to move a horizontal distance of about 2 mm, 3 mm, or 4 mm to about 5 mm, 6 mm, or 7 mm. As the cap 60 is mounted on the cable 50, the cap 60 can force the reservoir connector 164 to slide along the conical surface 75 by moving the pump connector 162 and the reservoir connector towards each other to activate the dispensing unit 150. The spaced wall pair 72 and 74 can be continuous or segmented to accommodate the placement of the dispensing unit 150 within the cavity 70 of the cable 50. Once in place, the spaced walls 72 and 74 can provide a contact pressure on the reservoir connector 164 and the pump connector 162, thereby preventing disengagement during use.
    The consumer needs emerging and developed markets that require hair removal devices
    16/51 economical and intuitive (for example, razors or shavers) that include modern advantages, such as replaceable cartridges that follow the contours of the face during shaving or epilation and do not intentionally disengage from the handle. When the cartridge must be replaced, the cartridge should be able to be removed from the cable in a simple and intuitive manner. In addition, the cartridge must not accidentally disengage the cable during use. Since the dispensing unit 150 is properly positioned inside the cable 50, the cover 60 can be mounted on the dispensing unit 150 and on the cable 50. The cover 60 can have one or more cartridge retaining elements 66a and 66b. As shown in figure 3, the cartridge retaining elements 66a and 66b can be positioned between the pair of arms 56a and 56b of the cable 50 to prevent the arms 56a and 56b from flexing together and disengaging from the cartridge 12. The retaining elements cartridge 66a and 66b can be positioned between the pair of arms 56a and 56b when the lid 60 is in a closed position (i.e., the lid 60 is securely mounted on the handle 50). The cartridge retaining elements 66a and 66b can directly contact the pair of arms 56a and 56b to prevent the arms 56a and 56b from moving in close proximity and disengaging from the cartridge 12. When the cap 60 is not mounted on the cable 50 (this ie, cap 60 is in an open position), the cartridge retaining elements 66a and 66b can be spaced from the arms 56a and 56b (ie, not located between the arms 56a and 56b) allowing the cartridge arms 56a and 56b 12 flex towards each other from a first position (ie, a neutral position) to a second position. Arms 56a and
    17/51
    56b may be in close proximity in the second position to allow the cable 50 to engage and / or disengage the cartridge 12. The arms 56a and 56b may each have a pin element 58a and 58b that pivotably engage with a corresponding opening 16a and 16b inside the cartridge 12. For example, the pin elements 58a and 58b can be positioned inside the openings 16a and 16b. In certain embodiments, the openings 16a and 16b may extend completely through a pair of opposite end walls 18a and 18b of the cartridge 12 for improved engagement.
    In certain embodiments, the dispensing unit 150 is mounted on cable 50 after cartridge 12 is mounted on cable 50 so that applicator 100 is properly positioned. The dispensing unit 150 can be placed inside the cavity 70 of the cable 50. The reservoir connector 164 and the pump connector 162 can be placed between the inner walls 72 and 74. The alignment elements 102 and 104 of the applicator 100 can mount on the alignment elements 82 and 84 of the cable 50. The cover 64 (with fixed actuator 62) can be mounted on the cable 50 to secure the cartridge 12 and the dispensing unit 100. In certain embodiments, the cover 60 can have a or more flaps 68 towards one end of the cap 60 and one or more flaps 86a and 86b towards an opposite end of the cap 60 to help secure the cap 60 to the cable 50. The flap 68 can engage a notch 69 of the cable 50. The lid 60 can then be hinged to force the dispensing unit 150 further into the cavity 70 and to force the reservoir connector 164 and the pump connector 162 into close proximity to activate the dispensing unit. According
    18/51 shown in figure 3, the flaps 86a and 86b can be releasably secured within an opening 88 of the cable 50.
    With reference to figure 4, a perspective view of the hair removal device 10 is shown illustrating the cap 60 being mounted on the cable 50. The hair removal device 10 can have a release element 90 which slidably engages the cable 50. The release element 90 may have one or more of the flaps 92a and 92b that extend into the opening 88 on the cable 50 and engage the corresponding one or more flaps 8 6a and 8 6b of the cap 60. The release element 90 it may have a first position so that the flaps 92a and 92b are securely engaged with the corresponding flaps 86a and 86b. The release element 92 can be actuated to a second position so that the flaps 90a and 90b move forward (for example, to the cartridge 12) and disengage the flaps 86a and 86b to release the cap 60 from the cable 50.
    With reference to figure 5, a top view of the cartridge 12 is shown. The cartridge 12 can have an overall width w1 from one side end 18a to another side end 18b of about 30 mm, 35 mm, or 40 mm to about 45 mm, 50 mm, or 55 mm. Cartridge 12 can include a housing 20 sized to receive at least one blade 22 having a blade edge of 25. Housing 20 can be injection molded from a semi-rigid polymeric material, such as high impact polystyrene. Housing 20 can be molded from other semi-rigid polymers that have a Shore D hardness of about 60 to 140, including, but not limited to, Noryl ™ (a blend of polyphenylene oxide (PPO) and polystyrene developed with General Electric Plastics, currently
    19/51
    SABIC Innovative Plastics), acrylonitrile-butadiene styrene (ABS), acetal, polypropylene, high impact polystyrene, or any combination thereof. The blade 22 can be a cutting blade (for example, for a razor or shaver), a scraping blade (for example, for a depilatory device), or a pulling blade (for example, for an epilator). Although a blade 22 is shown, cartridge 12 may have more blades 22 depending on the desired performance and cost of cartridge 12 and
    of device in removal in hair 10. In certain modalities, the blade 22 may to be mounted on a lodging 20 and trapped by stacking The cold. Others methods of
    assembly known to those skilled in the art can also be used to secure and / or mount the blade 22 in the housing 20 including, but not limited to, wire winding, clamps, hot stacking, insertion molding, ultrasonic welding, and adhesives.
    The housing 20 can have a shield 24 in front of the blade 22 and a cover 26 behind the blade 16. The shield 24 can extend parallel to the blade 22 between the side ends 18a and 18b. The bulkhead 24 may have an overall width w 2 of about 25 mm, 30 mm, or 35 mm to about 40 mm, 45 mm, or 50 mm. In certain embodiments, the overall width w 2 of the bulkhead 24 may be about 75%, 80%, or 85% to about 90%, 95%, or 100% of the overall width Wi of the cartridge 12. Housing 20 may have a top surface 30 and 32 extending from the bulkhead 24 to the lid 26. In certain embodiments, the openings 16a and 16b may extend across the respective top surfaces 30 and 32. The housing 20 may have a wall of front end 34 extending between side ends 18a
    20/51 and 18b. The elongated recess 14 can extend from the front end wall 34 to the blade 22. The bulkhead 24 can have an internal rear wall 36 and a pair of internal side walls 38a and 38b that define the elongated recess 14. The elongated recess 14 can extends parallel to the blade 16. The elongated recess 14 can have an overall width W3 of about 36 mm between the pair of inner side walls 38a and 38b. The overall width w 3 can be greater than an overall length between the front end wall 34 and the inner rear wall 36. The ratio of the overall width of the elongated recess 14 to the overall length of the elongated recess 14 can be about 4: 1 , 5: 1, or 6: 1, at about 7: 1, 8: 1, or 9: 1. In certain embodiments, the overall width w 3 of the elongated recess 14 can be about 70%, 75%, or 80% to about 85%, 90% or 100% of the overall width of the housing 20 and / or bulkhead 24. For For example, the overall width w 3 can be about 15 mm, 20 mm, or 25 mm to about 30 mm, 40 mm, or 55 mm. The elongated recess 14 may have a depth as measured from the top of the bulkhead 24) of about 0.2 mm, 0.25 mm, or 0.3 mm to about 0.4 mm, 0.5 mm, or 0.6 mm. The front end wall 34 of the housing 20 can define a notch 40 that extends in the bulkhead 24. The notch 40 can be positioned inside the elongated recess 14 for a midline ML of the housing 20. The notch 40 can engage at least one applicator portion 100. The notch 40 can assist in maintaining the applicator 100 positioned within the recess 14 of the housing 20 during use. The notch 40 can have a depth (as measured from the top of the recess 14) of about
    21/51 of 0.2 mm, 0.25 mm, or 0.3 mm to about 0.4 mm, 0.5 mm, or 0.6 mm.
    bulkhead 24 may have one or more projections 42 behind the elongated recess 14 which are positioned along the overall width of the bulkhead 24 (for example, over about 70% to about 100% of the overall width of the bulkhead 24). Projections 42 can have different sizes, shapes and geometries. In particular, the projections 42 can be in the form of segments of protrusions or fins that are spaced or interconnected. The projections 42 can also have different patterns or can be oriented at different angles to the blades, for example, in the zigzag, angled bar, herringbone or checkerboard patterns. The projections 42 can also take the form of spaced fin segments that are arranged in generally oriented rows parallel to the blades or spaced fin segments that are arranged both in parallel and perpendicular to the blades. The projections 42 can also represent a raised area around one or more recesses in the bulkhead 24. In certain embodiments, the projections 42 can be spaced to define one or more open channels 44 extending across the blade 22. The bulkhead 24 it may have one or more side projections 45a and 45b on either side of the elongated recess 14 (i.e., between side end wall 18a and inner side wall 38a and between side end wall 18b and inner side wall 38b). The lateral projections 45a and 45b can be spaced apart to define one or more open channels 47a and 47b extending transversely to the blade 22.
    22/51
    The side projections 45a and 45b can also define one or more open channels 47a and 47b with respective side end walls 18a and 18b.
    The projections 42 (and the lateral projections 45a and 45b) can be configured to control the skin and can assist in the orientation of the hairs and the liquid to the blade 30. The bulkhead 24 can be integral with the housing 20 and molded from polymeric materials as high impact polystyrene (PEAI). The bulkhead 24 can be molded from other semi-rigid polymers having a Shore D hardness of about 60 to 140, including, but not limited to, Noryl ™ (a blend of polyphenylene oxide (PPO) and polystyrene developed with General Electric Plastics, currently SABIC Innovative Plastics), acrylonitrile-butadiene styrene (ABS), acetal, polypropylene, high impact polystyrene, or any combination thereof. Alternatively, the bulkhead 24 and / or the projections 42 can be molded from a polymer other than the housing 20. In certain embodiments, the bulkhead 24 and / or the projections 42 can be molded from a softer material than the of housing 20. For example, bulkhead 24 and / or projections 42 may be molded from materials having a Shore A hardness of about 20 to about 70, such as thermoplastic elastomers (ETPs), silicones, or rubbers.
    A cap that has a generally uniform surface can create a significant amount of friction and drag as the cartridge is passed along the surface of the skin. This is typically because the covers include an auxiliary shaving or waxing composite to provide a slippery substance to the skin of the
    23/51 user. The cap 26 may have a plurality of ridges 46 which define a plurality of ridges 48 which generally extend to traverse the blade 22. The ridges 46 can support the skin along a substantial length of the blade 20 for a more comfortable shave or shave. . The projections 46 also reduce the contact area of the total surface with the skin. The area of surface contact with the skin may be the total surface area of the top surface of all protrusions 46 that come into contact with the skin surface during shaving or epilation. The projections 46 may have either a generally flat top surface or a generally curved top surface. The top surface of the projections 46 can reduce the contact area of the lid 26 by about 30%, 40%, or 50% to about 60%, 70% or 80%. For example, if the lid 26 had a generally uniform surface with no protrusion, the contact area of the skin surface would be about 140 mm 2 . However, the contact area of the skin surface of the cap 26, as shown with the projections 46, can be about 30 mm 2 (a decrease of 79% in the contact area of the skin surface). In certain embodiments, the contact area of the skin surface of the lid 26 can be about 25 mm 2 , 35 mm 2 , 45 mm 2 , or 55 mm 2 to about 75 mm 2 , 85 mm 2 , or 95 mm 2 . The projections 46 can be generally rectangular or trapezoidal in cross section with an aspect ratio of less than 2: 1, so that a base of the projection 46 is generally the same size as a top surface of the projection 16. For example , the projections 46 can have an aspect ratio of about 1: 1, 1: 1.3, or 1: 1.5 to about 1: 1.6, 1: 1.7, or 1: 1.9. An
    24/51 higher aspect ratio can cause the bumps 46 to scratch the user's skin resulting in an uncomfortable experience. A top surface of the projections 46 may be generally flat with a smooth finish to reduce drag against a skin surface. The projections 46 can be generically spaced equidistantly and can generally extend the entire length of the lid 26. Alternatively, the projections 46 can extend from about 70% to about 95% of the length of the lid 26. The projections 46 can have a pitch of about 0.25 mm, 0.50 mm, or 0.70 mm to about 1.0 mm, 1.25 mm, or 1.5 mm.
    Grooves 48 can have a depth of about 0.05 mm, 0.1 mm, or 0.2 mm to about 0.25 mm, 0.4 mm, or 0.6 mm. In certain embodiments, the projections 46 and the grooves 48 can extend at least to a rear end wall 52 of the housing 20. The rear end wall 52 can be curved to provide a smooth transition from the lid 26. The projections 46 and the grooves 48 can also be curved as they transition to the rear end wall 52. The grooves 48 can provide a path to remove excess preparation for shaving or epilation from the skin surface during shaving or epilation . Removing the preparation for shaving or waxing tends to be an indicator for most users that a certain area of skin has been properly shaved or shaved. If preparation for shaving or waxing is left behind, a consumer may shave or shave the area unnecessarily again, thus increasing the likelihood of incisions and cuts. Grooves 48 can be
    25/51 generally concave, which can optimize the rinsing of the lid 26. Channels with sharp corners or protrusions with straight edges can be difficult to rinse, thus leaving behind shaving or depilation aid and shaving remains or hair removal.
    Generally, shaving or shaving cartridges include a shaving or waxing aid, such as a lubricating strip attached to the lid or the lid can include a shaving or waxing aid composite to provide a slippery substance to the user's skin. Although these types of lids with grease strips and lubricating substances are very slippery when wet, they can become very slippery for a shaver or shaver that does not require a shaving or waxing aid. In addition, lubrication strips can increase the cost of the cartridge. In addition, the surface containing the measured substance as the lubricating strip or shaving or waxing composite wears out. The user often has to replace the cartridge, not because the blade is damaged, but because the cap (lubrication strip) no longer provides a slippery or comfortable shave or epilation. Wearing lubricating substances on certain razors or shavers is even more problematic because the cap and the lubrication strip are used to achieve the razor or shaving angle of the blade. As the lubricating substances wear out, the angle of shaving or shaving can be changed, resulting in a more aggressive and uncomfortable shave or shave. In certain areas of the world, razors or shavers are not used and
    26/51 stored in controlled environments, and are thus more sensitive to heat and humidity. Lubricating substances can experience even greater wear and dry faster in hot environments. The shaving aid or cap waxing composite can release unnecessarily slippery substances when the shaving or shaving cartridge is not being used, specifically areas of the world with increased humidity. Cap 26 can provide a low-cost alternative to caps that include a lubricating strip attached to the cap or caps that have a shaving or waxing aid composite that provides a slippery substance. The cap 26 can provide a consistent shaving or shaving angle and allows for adequate lubricity and comfort.
    Lid 26 can be integral with housing 20 or molded separately and then mounted on housing 20. The lid can be molded from polymers such as high impact polystyrene (PEAI), .in other semi-rigid polymers such as polypropylene (PP) and acrylonitrile butadiene-styrene (ABS) can also be used. Semi-rigid materials, such as polystyrene-based plastics, maintain the geometry of the lid 26 and the housing 20 during shaving or epilation, thereby further reducing drag and friction against the skin surface. Additives such as silicone, polytetrafluoroethylene (PTFE) or PPO can be added to the polymer to optimize the lubricity of the cap 26 surface against the skin surface during shaving or epilation. In certain embodiments, the lid 26 can be integral with the housing 20. The material of the lid 26 is
    27/51 composed of material that does not degrade or wear out over time so that the cap 26 maintains its geometry regardless of the blade 22 becoming damaged. The user may be able to get more shaving and hair removal from the same cartridge 12 because cartridge 12 would need to be replaced only when blade 22 has become severely damaged, which can vary greatly depending on the user. The cartridge 12 would not need to be replaced prematurely due to the discomfort that is the result of a used cap 26.
    In certain embodiments, the cap 26 can be molded from a shaving or epilation aid to provide increased lubrication to the skin surface during shaving or epilation. Alternatively the cap 26 may have a separate molded or extruded component This is fitted to the housing 20. For example, the housing 20 may have an auxiliary shaving or epilation strip fitted to the lid 26. The auxiliary shaving or epilation strips may comprise a matrix of a water-insoluble polymer and, dispersed within the matrix, a water-soluble polymer lubricating the skin. Alternatively, the shaving or shaving aid composition may comprise a water-insoluble polymer wrap which surrounds a core that includes a water-soluble polymer lubricating the skin. Suitable water-insoluble polymers that can be used for the matrix (or wrap) include polyethylene, polypropylene, polystyrene, butadiene-styrene copolymer (for example, medium and high impact polystyrene), polyacetal, acrylonitrile-butadiene-styrene copolymer, copolymer
    28/51 ethylene-vinyl acetate and blends such as polypropylene / polystyrene blend, with a high preference of a high impact polystyrene (ie polystyrene butadiene), such as Mobil 4324 (Mobil Corporation). Suitable water-soluble polymers for skin lubricants include polyethylene oxide, polyvinyl pyrrolidone, polyacrylamide, hydroxy propyl cellulose, polyvinyl imidazoline, and polyhydroxyethyl methacrylate. Other water-soluble polymers may include polyethylene oxides, generally known as POLYOX (available from Union Carbide
    Corporation), or ALKOX (available from Meisei Chemical Works, Kyota, Japan). These polyethylene oxides will preferably have a molecular weight of about 100,000 to 6 million, with the highest preference of about 300,000 to 5 million. Polyethylene oxide can comprise a blend of about 40 to 80% polyethylene oxide that has an average molecular weight of about 5 million (e.g.
    POLYOX COAGULANT) and about 60 to 20% of polyethylene oxide which has an average molecular weight of about 20 300,000 (for example, POLYOX WSR-N-750). The polyethylene oxide blend can also advantageously contain up to about 10% by weight of a low molecular weight polyethylene glycol (i.e. MW <10,000), such as PEG-100. The shaving or waxing auxiliary composition may also optionally include a complex of inclusion of skin softening agents with a water-soluble release agent of low molecular weight cyclodextrin such as polyethylene glycol (for example, 1 to 10% by weight ), water-swellable release enhancing agents such as 30 cross-linked polyacrylics (eg 2 to 7% by weight), dyes, antioxidants, preservatives, agents
    29/51 microbicides, beard conditioners, astringents, depilatories, medicinal agents, conditioning agents, cooling agents, etc.
    With reference to figure 6, an overall view
    in one unit dispensing 150 is illustrated. THE unity in dispensation 150 can have a applicator connector hollow 110 coupled a, and in communication of fluid with, The apl icator 100. For example, an far end 112 of
    Applicator connector 110 can be fitted to the press within an opening 106 of applicator 100. Applicator connector 110 may comprise a semi-rigid polymeric material and applicator 100 may comprise a resilient polymeric material that conforms around end 112 of the connector. applicator 110. Applicator connector 110 may have a second end 114 with an opening 116 sized to receive a first valve 118. The second end 114 of applicator connector 110 may be coupled to, and in fluid communication with, the pump 160. Pump 160 may comprise an elongated resilient tube 166 having a first end 168 snapped onto the second end 114 of applicator connector 110. Applicator connector 110 may have a shoulder-shaped portion 120 to prevent the pump 160 extends far over applicator connector 110, which can cause the first valve 118 to travel outside the second end 114 of the applicator connector and become housed within the resilient tube 166. If the first valve 118 becomes housed within the resilient tube 166, the dispensing unit 150 may become inoperative or leak. The resilient tube 166 can have a second
    30/51 end 170 coupled to one, in fluid communication with the pump connector 162. The pump connector 162 can be semi-rigid and have a first end 172 snapped onto the second end 170 of the resilient tube 166. The pump 162 may have a second end 174 with an opening 176 extending through the pump connector 162. Opening 176 may be sized to receive a second valve 178 (for example, a duckbill valve). Valves 118 and 178 can be one-way valves (for example, check valves, clack valves, and non-return valves) that are connected in series. Examples of one-way valves that can be used include, but are not limited to, ball check valves, balance check valves or inclined disc check valves, stop check valves, lift check valves, and valve duckbill. The positioning of valves 118 and 178 inside applicator connector 164 and pump connector 162 saves space and also helps to prevent valves 118 and 178 from moving out of position.
    The dispensing unit 150 may have a reservoir conduit 180 with a first end 182 and a second end 184 with one or more openings 186 extending through an outer wall 188 of the second end 184. The first end 182 can be coupled to, and in fluid communication with, the second end 174 of the pump connector 162. For example, the first end 182 may have an opening 190 which is snapped onto the second end 174 of the pump connector 162. The second end 184 of the
    31/51 reservoir conduit 180 can fit within an opening 165 of a first end 167 of reservoir connector 164. Reservoir 220 can be sealed around reservoir connector 164 as at least one second end 169 of connector of the reservoir 164 inside the reservoir 220. The second end 169 of the reservoir connector 164 can have an opening 171 sized to receive a plug 202. The plug 202 can have a first end 204 with a recess 206. A distal end 173 of the connector of reservoir 164 can fit inside recess 206 of plug 202.
    With reference to Figures 7A and 7B, the unit in dispensing 150 is shown at first position (this is, closed position). The figure 7B illustrates the reservoir 220 how strictly transparent to show the inside of reservoir and help at description of the unit in dispensation 150. In the first position, the 160 pump and ! THE
    applicator 100 may not be in fluid communication with reservoir 220. Pump connector 162 may have a shoulder 161 that is spaced from shoulder 163 of reservoir connector 164 in the first position. In addition, the second end 184 (not visible in figures 7A and 7B) of reservoir conduit 180 can be positioned inside reservoir connector 164. Openings 186 (not visible in figures 7A and 7B) reservoir conduit 180 can be blocked by reservoir connector 164 and / or plug 202 to prevent liquid flow from reservoir 220 to pump 160. Consequently, applicator 100 and pump 160 are not in fluid communication with reservoir 220 in the first
    32/51 position and pump 160 is unable to transport liquid from reservoir 220 to applicator 100.
    As shown in figures 8A and 8B, pump connector 162 and / or reservoir connector 164 can be moved from the second position (for example, activated position).
    In the second position, the shoulder 161 of the pump connector 162 may be in contact with the shoulder 163 of the reservoir connector 164. It is understood that in the second position the shoulders 161 and 163 can be moved closer, but may or may not be 10 in direct contact. In addition, the second end 184 of the reservoir conduit 180 can extend out of the reservoir connector 164 so that the openings 186 of the reservoir conduit 180 are no longer blocked by the reservoir connector 164 15 preventing the flow of liquid from from reservoir 220 to pump 160. Consequently, applicator 100 and pump 160 may be in fluid communication with reservoir 220 because the liquid is able to enter openings 186 of reservoir conduit 180 and flow 20 through reservoir conduit 180 for pump 160. Pump 160 may then be able to transport the liquid to applicator 100. In certain embodiments, the second position may be permanent (that is, when the dispensing unit 150 is in the second position, it is locked and 25 cannot be moved back to the first position).
    When the reservoir is empty, the reservoir may not be able to be filled and resealed, (and thus resold). Consequently, the consumer knows that when they purchase the dispensing unit 150 in the first position, the contents are sealed and not contaminated. In addition, the consumer knows that the liquid contained in the
    33/51 reservoir 220 is consistent with the ingredients listed on the packaging by the original manufacturer.
    The dispensing unit 150 can also be sold as a separate consumable which the consumer purchases 5 and inserts into the hair removal device 10 to activate the dispensing unit 150. The dispensing unit 150 can also be sold with the hair removal device hair 10. The dispensing unit 150 can be in the first position (ie, sealed) or in the second position 10 (ie, activated) when sold with the hair removal device 10. As previously explained above, in certain embodiments, it may be advantageous for shoulders 161 and 163 to be forced together by the cable 50 and the cap 60 during the assembly of the hair removal device 10.
    Alternatively, the consumer can move shoulders 161 and
    163 together with the hand. However, due to space limitations, pump connector 162 and reservoir connector 164 are relatively small; therefore, it may be difficult for the consumer to apply the force 20 necessary to move the pump connector 162 and / or the reservoir connector 164 to the second position. In certain embodiments, the dispensing unit 150 and / or the cable 50 can provide audible feedback, a click sound, when the dispensing unit 150 is placed 25 in the second position. Audible feedback can be produced by pump connector 162 and reservoir connector 164 moving together or reservoir conduit 180 moving in relation to reservoir connector 164. Audible feedback can also be produced from dispensing unit 150 fully engaging cable 50 (for example, when the
    34/51 cover 60 is mounted on cable 50). The cap 60 which engages the cable 50 (for example, the cap 60 which engages the release element, as shown in figure 4) can also produce audible feedback informing the consumer that the dispensing unit 150 is activated.
    Referring to figure 9A, an enlarged bottom view of the hair removal device 10 is shown. Applicator 100 may have a bulkhead 120 with a plurality of projections 122 defining a plurality of opening channels 124 which are transversal to the blade 22 (for example, the edge of the blade 25). Applicator 100 may have at least one outlet port 128 in front of the bulkhead 120 on the same side as blade 22. In certain embodiments, applicator 100 may have only a single outlet port 128. Outlet port 128 may be positioned towards a midline of applicator 100 (for example, along line 9B-9B). The projections 42 of the bulkhead 24 can be aligned with the projections 122 of the applicator 100 to define a plurality of opening channels 126 extending transversely to the blade 20 (i.e., the channels 44 of the cartridge bulkhead 24 can be aligned with the channels 124 applicator screen 120). The liquid can be passed from the outlet port 128 and through the opening channels 126 of the bulkhead 120 and the blade 22. The applicator 100 can also apply a layer of liquid to the skin surface during a stroke of the hair removal device 10 against the skin. The projections 122 can prevent the cartridge 12 from sliding erratically over the face during a shaving or waxing course. In addition, protrusions 122 can decrease the surface area in contact with skin and provide channels
    35/51
    for the liquid to flow for the blade 20 for the increase gives lubrication and a shaving or waxing more comfortable. 0 applicator 100 can have one baffle 130 at
    front of the bulkhead 120 with a resilient front wall 132 that defines an elongated recess 134. The deflector 130 can increase the fluid dispersion to a wider skin surface. The elongated recess 134 of the baffle 130 can have a width of about 15 mm, 20 mm, or 25 mm to about 30 mm, 35 mm, or 40 mm. The elongated recess 134 may have a length of about 1.5 mm, 2.0 mm, or 2.5 mm to about 3.0 mm, 3.5 mm, or 4.0 mm. The depth of the elongated recess 134 can be greater than the width of the elongated recess 134. In certain embodiments, the depth of the elongated recess 134 can be about 3 mm, 4 mm, or 5 mm to about 6 mm, 7 mm, or 8 mm. The outlet port 128 can be positioned inside the elongated recess 134. The baffle 130 can control the flow of liquid from the outlet port 128 to the screen 120 of the applicator 100. The elongated recess 134 can be filled with liquid which is pumped from reservoir 220 (not shown) to outlet port 128. The elongated recess 134 may have a first bulk of about 0.2 ml to about 0.5 ml when the resilient front wall 132 is in a first position and a second volume when the flexible front wall is in a second position. The resilient front wall 132 can flex from the first position to the second position during a stroke (for example, a shaving or waxing stroke) of the hair removal device 10 to disperse the liquid contained within the elongated recess
    36/51
    134 for screen 120 of applicator 100. In certain embodiments, the second volume can be about 35%, 45%, or 55% to about 75%, 85%, or 95% less than the first volume. The elongated recess 134 can provide the consumer with a visual indication of the amount of liquid that is felt applied and that the pump 160 (not shown) is functioning properly (for example, the elongated recess 134 is sufficiently filled with liquid).
    Applicator 100 can be molded from a thermoplastic elastomer such as TPE (thermoplastic elastomers). However, other resilient materials having a Shore A (ISO 868) hardness of about 50 to about 90 can be used including, but not limited to, silicone, latex, polyvinyl chloride (PVC), rubber, and polyurethanes. Applicator 100 may comprise a material that has a tensile strength at break of about 8 N / mm 2 , 9 N / mm 2 , or 10 N / mm 2 to about 12 N / mm 2 , 13 N / mm 2 , or 14 N / mm 2 (ISO 37). Applicator 100 can comprise a material that has a percentage elongation at break of about 300% mm 2 , 400%, or 500% to about 600% mm 2 , 700%, or 800% (ISO 37). The hardness, tensile strength, and / or elongation percentage of the applicator 100 can provide the front wall 132 of the baffle 130 with sufficient resilience to flex and disperse the liquid. In certain embodiments, the front wall 132 may have a thickness of about 0.3 mm, 0.4 mm, or 0.5 mm to about 0.6 mm, 0.8 mm, or 1.0 mm so that the front wall 132 has sufficient resilience to flex and disperse the liquid. Deflector 130 allows control and release of liquid during a shaving or waxing course. The elongated recess 134 allows the same
    37/51 volume of liquid is dispersed with a single outlet port 128. Typically the same amount of volume would have to be dispersed through a plurality of smaller orifices (outlet ports). Smaller outlet ports may need a pump with more pressure, and outlet ports may become easily clogged with shaving or shaving remnants. Smaller outlet ports also require liquids with lower viscosity, which can limit the shaving or shaving lotion or preparation that can be used with the hair removal device 10. In certain embodiments, the size of outlet port 128 can be about 1 mm 2 , 1.5 mm 2 , or 2 mm 2 to about 4 mm 2 , 6 mm 2 , or 8 mm 2 .
    With reference to figure 9B, an enlarged partial cross-sectional view of the hair removal device 10, taken in general along the line 9B-9B of figure 9A is shown. The dispensing unit 150 can comprise flexible components, such as applicator 100, resilient tube 166, and reservoir 220 to provide functionality while being able to conform to size restrictions within the cable 50. Resilient tube 166 can also be compressed anywhere along its outer surface (ie, 360 degrees) to open valve 118 while valve 178 remains closed to pump liquid from reservoir 220, thus allowing for increased flexibility of industrial design to guide the dispensing unit 150 inside the cable 50. The applicator 100 can be removably mounted to the cartridge 12 (for example, the bulkhead 120 of the applicator 100 can be positioned inside the recess 14 of the housing 20,
    38/51
    according shown in figure 9A) . 0 applicator 100 can to sustain and hitch the cartridge 12 just right wherein cartridge 12 articulates in relation to cable 50. On measure in that cartridge 12 articulate, The applicator 100 can 5 flex and apply a force in change against
    cartridge 12. Applicator 100 can tilt the cartridge towards a neutral position. Consequently, applicator 100 can eliminate extra components, serving two functions, (1) distributing and dispersing liquid and (2) tilting 10 the cartridge 12. 0 applicator 100 can have a base element
    135 that defines output port 128 and holds the cartridge
    12. The base element 135 can extend transversely to the bulkhead 120 of the applicator 100. The base element 135 can contact and support the cartridge 12. In certain embodiments, the applicator 100 (for example, the base element 135 and the bulkhead 120) can limit a rotation angle of the cartridge 12 with respect to the cable 50. The cartridge 12 can pivot a total of 30 degrees to a total of about 45 degrees with respect to the cable 50.
    The resilient tube 166 can be directly or indirectly actuated at any point around its circumference (for example, by direct contact by a consumer finger or the actuator 62). Once the dispensing unit 150 is activated, applicator 100 may be in fluid communication with pump 160 and reservoir 220.
    The resilient tube 166 of the pump 160 allows the resilient tube 166 to be actuated 360 degrees from the surface of the resilient tube. Consequently, the resilient tube 166 allows actuator 62 to be placed at any location of the hair removal device 10 (for example, at the top, bottom, or sides of the cable 50 and / or
    39/51 cover 60). Actuator 62 (for example, a button) can be exposed on the outer surface 64 of cover 60 and aligned with pump 160 so that when actuator 62 is pressed on flexible tube 166 it is compressed to transport liquid from the reservoir 220 for applicator 100. Resilient tube 166 can be arranged between the first and second valves 118 and 178 (respectively). The resilient tube 166 can have a neutral position with both valves closed and a second position (i.e., when positive or negative pressure is applied) with an opening valve 118 or 178 and a closed valve 118 or 178. For example, in the second position, the resilient tube 166 can be compressed resulting in positive pressure being applied to the resilient tube 166 to open one of the valves 118 or 178. In the compressed position, the liquid can travel from the resilient tube 166 through the first 118 positioned inside the applicator connector 164, through the applicator 100 and outside the outlet port 128. The outlet port 128 can at least partially fill the elongated recess 134. For example, the liquid volume of the resilient tube 166 can be about 0.1 ml to about 0.2 ml. It may be advantageous to avoid overfilling the elongated recess 134 which can result in the liquid being dispensed over the cable 50. In certain embodiments, the ratio between the volume of the pump 160 (i.e., resilient tube 166) and the volume of the elongated recess 134 can be about 1: 2 to about 1: 5. Consequently, the consumer can make several strokes with the hair removal device 10 before having to refill the elongated recess 134. Furthermore, it is inconvenient for the consumer to operate the pump 160 many times.
    40/51 times in order to fill the elongated recess 134. In addition, if the volume of the elongated recess 134 is very large or if only or if only a single actuation of the pump fills the elongated recess 134, excess liquid can be wasted .
    In certain embodiments, the actuator 62 can directly contact the resilient tube 166 to compress the resilient tube 166 and open valve 118, while valve 178 remains closed. Valves 118 and 178 can each have a flat end 119 and 179 (respectively) when closed. Flat ends 119 and 179 can open to allow liquid to pass when pressure is applied and a closed position to prevent liquid flow back when pressure is removed (for example, when actuator 62 is released from resilient tube 166 ). Valve 178 can open (and valve 118 can close) when negative pressure is reached within resilient tube 166 (for example, when actuator 62 is released and no longer compresses resilient tube 166). The resilient properties (for example, elongation and toughness at break) and the wall thickness of the resilient tube 166 can facilitate the resilient tube 166 to return to its natural state and achieve negative pressure inside the resilient tube 166. Whenever the valve 118 is closed and the valve 178 is opened, the liquid can travel from the reservoir 220, through the openings 186 of the reservoir duct 180, through the second valve 178 positioned inside the pump connector 162 and in the resilient tube 166. The positioning of a resilient tube between a pair of one-way valves positioned in series prevents the flow of debris from returning
    41/51 shaving or waxing and microbes inside pump 160 and reservoir 220. In certain embodiments, resilient tube 166 can return actuator 62 back to its original position. Consequently, an additional return force element (for example, a spring) is not necessarily required to return the actuator 62 back to its original position. The resilient tube 166 can be extruded or molded from materials having a Shore A hardness of about 40 to about 90 (ISO 868), including, but not limited to, thermoplastic elastomers (TPEs), polyvinyl chloride (PVC) , silicones, rubbers, or any combination thereof. The resilient tube 166 may comprise a material that has a tensile strength at break of about 8 MPa, 9 MPa, or 10 MPa at about 12 MPa, 13 MPa, or 14 MPa (ISO 37). The resilient tube 166 may comprise a material that has a percentage elongation at break of about 300% mm 2, 400%, or 500% to about 600% mm 2 , 700%, or 800% (ISO 37). The resilient tube 166 may have a nominal wall thickness of about 0.5 mm, 0.75 mm, or 1 mm to about 1.25 mm, 1.5 mm, or 2 mm to provide sufficient flexibility to allow the efficient compression of the resilient tube 166 by the actuator 62, but not so flexible that the resilient tube 166 does not return to its original position after having been repeatedly compressed.
    With reference to figure 10, a perspective view of the personal care bottle 250 is shown, which can be incorporated into the hair removal device 10 of figure 1. The personal care bottle 250 can have a pair of opposite walls (for example,
    42/51 (top surface 280 and bottom surface 282) with different wall thicknesses. In certain embodiments, the personal care bottle 250 can be blow-molded (for example, blow-molded injection) from polymeric materials including, but not limited to, polyolefins (for example, polyethylene and polypropylene), polyesters ( for example, PET), nylon, PVC, and TPEs. The personal care bottle 250 may have sufficient rigidity to securely mount to the handle 50, and sufficient flexibility to allow at least a portion of the personal care bottle 250 to be easily compressed (for example, a material having a Shore D hardness of about 30 to about 80). The personal care bottle 250 may have a first end wall 252 with a connector 254 (e.g., a projection) for removably securing the personal care bottle 250 to the cable 50 (not shown) of the hair removal device 10 (not shown). A first and second opposite side walls 256 and 258 can each have an alignment element 260 and 262 (for example, an elongated groove or rail extending along the respective opposite side walls 256 and 258 transverse to the first wall of end 252). The personal care bottle 250 may have a lid 264 opposite the first end wall 252.
    The personal care bottle 250 can define a cavity 294 (not shown) containing a liquid. The liquid in the personal care bottle 250 may include one or more skin care compositions suitable for topical use. Some non-limiting examples of compositions suitable for skin care include
    43/51 aerosol or non-aerosol products such as shaving or hair removal gels, shaving or hair removal foams, shaving or hair removal lotions, shaving or hair removal oils, skin care compositions, cleansing creams, conditioning aids, depilatories , balms, lotions, moisturizers, etc. Examples of various types of shaving or aerosol hair removal preparations are available in the Patents. Nos. 5,560,859; 5,587,156; 5,326,556; and 5,500,211; and U.S. Patent Publication No. 2007/0207106. Preparations for shaving or waxing non-aerosols typically include emulsions (creams / lotions) or gels, which most commonly consist of thickened polymeric surfactant systems. See for example US Patent Nos. 5,902,574 and 5,262,154; and U.S. Patent Publication No. 2007/0207106. In addition, the skin treatment composition can be a foaming or non-foaming product. Some non-limiting examples of non-foaming products are available at: WO9318740; and U.S. Patent Nos. 4,585,650, and 3,072,536.
    In one embodiment, the liquid contained in the personal skin care bottle 250 and the liquid contained in reservoir 220 (not shown) are not the same. For example, in one embodiment, the liquid contained in reservoir 220 may comprise a liquid composition for skin or hair that is applied to the skin before the liquid contained in the personal care bottle 250. The liquid contained in reservoir 220 can prepare and / or assist in hair removal, such as one or more of the foaming and non-foaming shaving or waxing preparations mentioned above (gels,
    44/51 foams, lotions, oils, cleaning creams, depilatories, desensitizing agents, etc.). In this same embodiment, the liquid contained in the personal care bottle 250 may comprise a skin care composition that can be a moisturizer, lotion, balm, cooling agent, or other skin conditioning aid. In addition, one or more of the liquids contained in the reservoir either in reservoir 220 or in the personal care bottle 250 may comprise the benefit of agents suitable for skin and / or hair that can be useful for a number of different desirable effects including exfoliation, cooling effects, cleansing , hydration, heating or thermogenic effects, conditioning, and the like. Beneficial agents suitable for the skin and / or hair for inclusion in the razor or shaver liquid are disclosed in U.S. Patent 6,789,321 and US Patent Publication 2008/0069784. For example, suitable agents include, but are not limited to, shaving or hair removal soaps, lubricants, skin conditioners, skin moisturizers, hair conditioners, hair conditioners, fragrances, skin cleansing creams, bactericidal lotions or medicinal, blood coagulants, anti-inflammatory, astringent, tanning, fragrance, and combinations thereof.
    Referring to figure 11, the perspective view of the personal care bottle 250 and handle 50 is shown. The personal care bottle 250 can slide the handle 50 slidably. The handle 50 can define an opening 266 sized to receive a portion of the personal care bottle 250. The first
    45/51 end wall 252 and connector 254 can be arranged inside opening 266. Opening 266 of cable 50 can receive about 50%, 60%, or 70% to about 80%, 90%, or 100 % of the top surface 280 of the personal care bottle 250. The opening 266 of the handle 50 can also receive about 25%, 30%, or 35% to about 55%, 65%, or 75% of the first and second opposite side walls 256 and 258 of the personal care bottle 250. The bottom surface 282 can be spaced from the handle 50 so that a consumer can squeeze the bottom surface 282 when the personal care bottle 250 is mounted to the handle 50 The positioning of the top surface 280 and the first and second opposite side walls 256 and 258 inside the opening 266 reduces the likelihood that the consumer may unintentionally release liquid by squeezing the personal care bottle 250. In addition, the surface exposed background 282 can intuitively provide a area for the consumer to squeeze the personal care bottle 250 to release liquid. The cable 50 may have a pair of alignment elements 268 and 270 (for example, an elongated groove or rail) that engages the corresponding alignment elements 260 and 262 of the personal care bottle 250. The alignment elements 268 and 270 of the cable 50 and alignment elements 260 and 262 of the personal care bottle can facilitate the secure attachment of the personal care bottle 250 to the handle 50. The handle 50 can engage the personal care bottle 250 in three different locations (for example, the first and the second opposite side walls 256 and 258 and the first end wall 252) to hold the personal care bottle tightly
    46/51
    250. The personal care bottle 250 may unintentionally disengage the cable 50 or become damaged during use. Additional forces can be applied to the personal care bottle 250 during use because the personal care bottle 250 is exposed at one end of the handle 50. Consequently, the personal care bottle 250 can be attached on three different sides (for example, alignment elements 260 and 262 and connector 254).
    The cable 50 may have a pair of displacement retaining surfaces 272 and 274 that contact a corresponding pair of shoulders 276 and 278 in the personal care bottle 250. The shoulder 276 (for example, first shoulder) can be located on the top surface 280 from the personal care bottle 250 towards the lid 264. The shoulder 278 (for example, second shoulder) can be moved laterally from the shoulder 276 (that is, towards the first end wall 252) and located on the surface of opposite bottom 282. The offset shoulder pair 276 and 278 may allow bottom surface 282 to be exposed (for example, spaced from handle 50) when the personal care bottle 250 is attached to handle 50. For example, shoulder 278 can contact a surface 274 of the cable to prevent the bottom surface 282 from being received inside the opening 266 of the cable 50. In addition, the offset shoulder pair 276 and 278 allows the top surface 280 to be covered (for and example, protected) by cable 50. Consequently, the top surface 280 can be positioned inside the opening 266 of the cable while the bottom surface 282 is not positioned inside the opening 266 (i.e.,
    47/51 exposed) after the personal care bottle 250 is attached to the handle 50. The damage and disengagement of the personal care bottle can also be reduced because the personal care bottle 250 is supported by the handle 50 on several sides (for example, the top surface 280, the first end wall 252, and at least a portion of the opposing first and second side walls 256 and 258 (see figure 10) can be positioned inside the opening 266 of the cable 50). In certain embodiments, at least a portion of the first and second opposing side walls 256 and 258 can be positioned within the opening 266 of the cable 50. For example, about 20%, 25%, or 30% to about 60% , 70%, or 80% of the first and second opposite side walls 256 and 258 can be positioned inside the opening 266.
    The bottom surface 282 can have a wall thickness This is less than the wall thickness of the top surface 280. In certain embodiments, the wall thickness of the bottom surface 282 can be about 30%, 40%, or 50 % to about 70%, 80%, or 90% less than the top surface wall thickness 280. For example, the bottom surface wall thickness 282 can be about 1.2 mm and the wall thickness the top surface 280 can be about 3.8 mm (about 68% reduction in wall thickness). The reduced wall thickness of the bottom surface 282 allows the consumer to easily compress the bottom surface 282 to release the liquid from the personal care bottle 250. For example, a polyethylene bottle that has a 68% reduction in wall thickness (with the same dimensions given above) can result in a 70% reduction in the force required to compress the
    48/51 bottom surface 282 from a distance of 2 mm compared to top surface 280. In certain embodiments, the force required to compress the bottom surface 282 can be about 30%, 40%, or 50% at about 70%, 80%, or 90% less than the force required to compress the top surface 280 the same distance. The bottom surface 282 may also include one or more marking areas 284 (for example, one or more grooves extending around a circumference, such as an oval). Marking areas
    284 may indicate a reduced wall thickness area
    285 (for example, located inside the marking areas) signaling the consumer where to press on the personal care bottle 250 to release the liquid. Marking areas can also include words or symbols, such as, as you press here.
    With reference to figure 12, an enlarged partial cross-sectional view of the hair removal device 10, taken in general along line 12-12 of figure 1B is illustrated. A second end wall 290 opposite the first end wall 252 can connect to the bottom and top surfaces 280 and 282. The second end wall 290 can define an opening 292 in fluid communication with the cavity 294. A cap 264 can be mounted to a second end wall 290 to prevent liquid from flowing out of opening 292. In certain embodiments, opening 292 can be positioned along second end wall 292 towards top surface 280. The lid 264 may have a non-parallel rear wall 298 (i.e., an obtuse angle) to a first end wall 252. In certain embodiments, the rear wall 298 of the cover may have an angle of about
    49/51 degrees, 20 degrees, or 25 degrees at about 30 degrees, 35 degrees, or 40 degrees with respect to the first end wall 252. Cap 264 can have a plug 296 protruding from the back wall 298 and positioned inside the opening 292 of the second wall 290. In certain embodiments, a hinge 300 can interconnect the lid 264 to the personal care jar 250 (for example, the bottom surface 282). The cable 50 can define an internal opening 255. The connector 254 can be arranged inside the opening to attach the personal care bottle 250 to the cable 50. In certain embodiments, the opening 250 can be in communication with the cavity 70 of the cable 50 .
    With reference to figure 13, a perspective view of the hair removal device 10 is shown with the cover 264 in a fully open position. In certain embodiments, the cap 264 can be attached to the personal care bottle 250 with the hinge 300. The hinge 300 can be moved from the opening 292 defined by the end wall 290 (i.e., spaced from the end wall 290) of the bottle to personal care 250. In certain embodiments, hinge 300 may be spaced from end wall 290 by about 5 mm, 10 mm, or 15 mm to about 20 mm, 25 mm, or 30 mm. Cover 264 and / or hinge 300 may be arranged at an angle (i.e., not parallel) to a second end wall 290 that defines opening 292. In certain embodiments, cover 264 and / or hinge 300 may be arranged at an angle of about 15 degrees, 20 degrees, or 25 degrees to about 30 degrees, 35 degrees, or 40 degrees with respect to a second 290 end wall. The angle and / or offset of a hinge 300 e / or cover 264 can allow the most
    50/51 access from opening 292 (that is, cover 264 opens more than
    180 degrees in relationship to a second wall in far end 290). At dimensions and values presented in this invention should not be understood as being
    strictly limited to the exact numerical values mentioned. Instead, unless otherwise specified, each of these dimensions is intended to mean both the mentioned value and a range of functionally equivalent values around that value. For example, a dimension revealed as 40 mm is meant to mean about 40 mm. In addition, dimensions must not be maintained to an impossibly high standard of metaphysical identity that does not allow for discrepancies due to typical manufacturing tolerances. Therefore, the term about should be interpreted as being within typical manufacturing tolerances.
