    CONTAINER TO STORE PERSONAL CARE ITEMS
    HISTORIC
    There are a variety of storage and dispensing containers on the market, particularly those for storing and dispensing personal care products. Personal care products, particularly wipes, have been made from a variety of materials that can be dry or wet when used. Wet wipes can be moistened with a variety of suitable cleaning solutions. Typically, baby wipes have been stacked in a container whether in a folded or unfolded configuration. For example, wet wipe containers have been available in which each of the wet wipes stacked in the container is arranged in a folded configuration such as a C-folded, Z-folded or quarter-folded configuration, as known to those skilled in the art. . Sometimes folded wet wipes have also been folded between them with the wet wipes immediately above and below the stack of wet wipes. The wipes have also been placed in containers in the form of a continuous web of material that includes perforations to separate the individual wipes and which are rolled into a roll. Such baby wipes have been used for baby wipes, hand wipes, household wipes, industrial wipes and the like.
    Conventional handkerchief containers have typically been designed for placement on a flat surface, such as a counter top, table or the like. Such conventional packaging is generally provided with a plastic container, tub or packaging that provides a sealed environment for the wet wipes to ensure that they do not become dirty and / or excessively dry. To access the tissues, many containers have an access lid that is opened by pressing a button on the top of the container.
    Some of these conventional packages have been configured to provide the dispensing of each wet wipe, one at a time, which can be done using one hand after use.
    2/16 container has been opened. Dispensing with one hand of each handkerchief individually is particularly desirable because the other hand of the user or caregiver is usually required to be used simultaneously for other functions. For example, when changing a diaper on a child, the caregiver typically uses one hand to hold and hold the child in a desired position while the other hand is trying to dispense with a baby wipe to clean the child. The caregiver may not want to look away from the child to open the container and access the tissues.
    A wide variety of wet wipe dispensing containers is currently available on the market. These containers can be broadly categorized into two classes: to pick up inside (reach-in} and sudden pop-up) Within the category of sudden projection, some containers provide a stack of flat, folded handkerchiefs which are most commonly dispensed from a tub. Other containers provide a roll of tissues, perforated at their ends, which are dispensed from a vertical cylindrical container. The containers of the sudden projection type have gained popularity because the wet wipe is more readily available to the user. While there is a great opportunity for the tissues in a sudden projection type container to dry at least partially, improvements to the container model have alleviated this problem.
    However, dispensing tissues from such conventional tissue containers has not been completely satisfactory. For example, for containers of the sudden projection type having a stack of tissues, there are times when the sudden projection feature fails and the user needs to reach inside the container to retrieve the next tissue. These failures are most commonly caused by folds between the wipes that have been lost. Therefore, there is a demand to provide a dispenser with a patterned dispensing divider that allows consumers to access tissues for easier dispensing and with fewer failures, particularly in a sudden projection tissue product format.
    RESUME
    3/16
    A container for storing personal care articles comprising a lid structure attached to the container is described. The lid structure has an upper lid portion connected to a base lid portion via at least one hinge, the upper lid portion having a lid clamping mechanism that extends from the opposite side of the hinge. The base lid portion includes a rigid opening surrounding a unitary dispensing partition that extends in an X direction and in a Y direction for the rigid opening, the unitary dispensing partition having a dispensing or slit opening formed therethrough.
    Typically, the unitary dispensing partition forms an arc in the X direction that extends at a first depth into an interior of the container in a Z direction. Conveniently, the first depth of the unitary dispensing partition extends into the interior of the container in the Z direction. for a distance of at least 5 mm. Even more conveniently, the first depth of the unitary dispensing partition extends into the container in the Z direction by a distance between about 5 and about 15 mm.
    The dispensing opening may include a continuous slot having two ends, the continuous slot extending a distance in an X direction along the arc. In this case, the two ends of the continuous slot reside in the arc at a second depth in the Z direction which is less than the first depth.
    container holds a stack of wet wipes located inside the wet wipe dispenser, each wet wipe having a front edge and a rear edge. During storage, the front edge of the tissue extends into a storage space between the dispensing partition and the top of the lid. Conveniently, the dispensing partition is a flexible material. Typically, the dispensing partition is a thermoplastic elastomer.
    The initiation of the separation of a subsequent handkerchief can occur in a medium portion of the leading edge of a first handkerchief. When this happens, the separation of the subsequent tissue
    4/16 occurs in portions of the outer edge of the back edge of a first handkerchief while a leading edge of the middle portion of the subsequent handkerchief is held in place by the dispensing opening. This results in less tissue falling back into the container and out of the dispensing position during use. Thus, the container will have fewer dispensing failures.
    container having the arc shaped dispensing partition described here has a dispensing failure rate of less than 8%.

    DETAILED DESCRIPTION
    In general terms, a container for storing personal care articles comprising a lid structure attached to the container is described. The lid structure has an upper lid portion connected to a base lid portion by means of at least one hinge, the upper lid portion having a lid fastening mechanism that extends from the opposite side of the hinge. The base lid portion includes a rigid opening surrounding a unitary dispensing partition that extends in an X direction and in a Y direction with respect to the rigid opening, the unitary dispensing partition having a dispensing slot formed therethrough. The unitary dispensing partition forms an arc that extends at a first depth into the container in a Z direction. The depth of the dispensing partition allows the personal care item to be stored in a sudden projection dispensing position with a larger portion of the article for care
    5/16 personnel extending from the dispensing slit. This allows for easier recovery of the product by a consumer and fewer dispensing errors.
    Reference will now be made in detail to the currently preferred embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation and is not intended to be a limitation. For example, features illustrated or described as part of a modality or figure can be used in another modality or figure to produce yet another modality. The present invention is intended to include such modifications and variations.
    As illustrated in Figures 1-3, a container 10 for storing personal care products having a lid structure 12 with a lid top 15 hingedly attached to a lid base 14 to allow a consumer to access the contents of the container through of the same. A tension member is positioned against the top of the lid and the base of the lid at the joint. The tension member is formed by a strip or strip of rubber or flexible plastic, such as silicone, and / or a metal spring. The end of the tension member forces against the top of the lid 15 to separate the lid top 15 and the lid base 14 when a consumer pushes a lid activation button 30 to open the lid structure 12.
    In exemplary embodiments, the personal care products stored in the container are baby wipes that are used for babies, baby wipes, household cleaning wipes, industrial wipes and the like. The lid structure 12 can be formed as an integral part of the container 10 or it can be positioned on a lid base 14. In an exemplary embodiment, the lid base 14 is connected to a container base 25 by means of a hinge 22 to enable a second opening for container 10. The consumer may then be able, if desired, to refill the container with additional tissues.
    product, for example, wipes or wet wipes, can be arranged in the dispenser in a way that provides convenient and safe dispensing one at a time and that
    6/16 help the tissues not to become dirty and / or excessively dry. For example, the tissues can be arranged in the dispenser or container as a plurality of individual sheets arranged in a stacked configuration to provide a stack of tissues that may or may not be folded individually. The wipes may be individual wipes that are folded in a C-fold, Z-fold, quarter-fold or other zigzag fold or in folded configurations or in unfolded configurations as known to those skilled in the art. These handkerchief configurations, as well as those discussed herein, can be provided by means known to those skilled in the art.
    Conveniently, the wipes can be arranged in the dispenser as a continuous web of interwoven wipes 50 which are folded in a stacked accordion-like configuration or on a roll. Individual wipes can be connected together along lines of fragility, such as perforation lines, to ensure that the rear wipe is in a position to be picked up by the user after the front wipe is removed. For example, wipes can be provided by a continuous web of material that has a series of lines of fragility extending across the width of the web. The portion of the material web between successive lines of fragility provides each individual scarf. The lines of weakness can be provided by means known to those skilled in the art such as perforations, notches or cuts in the material web. For example, lines of weakness or perforations can be provided in the material web by passing the material web between a die cutter roll and an anvil roll. After the fragility lines are incorporated into the material web, the web can then be arranged in a stacked configuration for easy insertion into the dispenser during its formation.
    Conveniently, the individual tissues can be folded together or continuously interconnected so that the front and rear edges of successive tissues, in the stacked configuration, interact for sudden projection dispensing. In such a configuration, the front edge of the rear scarf
    7/16 is loosened from the stack via the rear edge of the front handkerchief when the front handkerchief is removed by the user.
    The container can include any suitable number of individual wipes depending on the desired packaging and end use. For example, the container can be configured to include a stack of tissues that can include at least about 5 tissues and conveniently from about 8 to about 320 individual tissues, and most conveniently from about 16 to about 80 tissues . The size and shape of the tissue stack depends on the size and shape of the container and vice versa.
    Each tissue is generally rectangular in shape and defines a pair of opposite side edges 61, 63 and a pair of opposite end edges that can be referred to as a front edge 55 and a rear edge 60. The front edge 55 of each wet tissue is typically positioned in the dispenser within the dispensing hole to be gripped by a user to facilitate removal of the tissue from the container.
    In an exemplary embodiment, the lid base 14 contains a rigid opening 18 surrounding a dispensing partition of the sudden projection type 40 in which a flexible, rubber-like material having a slit or hole 30 through which the wet wipes are removed individually of the container. For sudden projection-type dispensing, the tissue will become separated or disjointed from the second adjacent tissue, subsequent in an interface that can be separated (for example, fragility line, adhesive bonding or other mechanism) after completely dispensing the first handkerchief and while a portion of the second handkerchief remains in the flexible orifice. The next dispensing handkerchief can be automatically maintained in the partially dispensed orifice with a portion of the handkerchief extending from the dispensing opening for later use (i.e., a sudden projection dispensing format). Alternatively, the next handkerchief may need to be fetched inside the dispenser in a similar way to the first handkerchief at a later time when it is desired, commonly called a pick-up dispenser, if the user pushed the next handkerchief back into the
    8/16 storage after the sudden release of the front scarf or the first scarf. In any case, after the desired number of tissues is removed, the top can be closed, with or without a tissue partially dispensed in the flexible orifice, as previously discussed. At a later time when another scarf (s) is desired, the preceding steps can usually be followed again.
    In an exemplary embodiment, dispensing partition 40 is a single section of material, unitary or undivided. The use of a unitary material section improves the moisture retention of the container. Other non-flexible materials have been used to provide similar arrangements. However, these non-flexible materials have been made with rigid plastic materials and are connected together using mechanical means. This creates larger spaces in the dispensing hole where moisture can be lost to the atmosphere during storage and the tissues become excessively dry.
    A portion of the unitary dispensing divider extends into the container base 25 in the Z direction. Typically, the unitary dispensing divider 40 forms an arc 35 in the x direction that extends from a first depth, Dl, to an interior 32 of the container 10 in a Z direction forming a storage space for a leading edge of the next handkerchief in a sudden projection dispensing format. The geometry of the arc 35 that extends the depth of the container in the Z direction provides the opportunity to offer more storage space under the mini lid to the front edge of the scarf. This allows the consumer to easily access the tissue inside the dispensing opening with less dexterity or without looking at the container. Thus, a caregiver, for example, could easily reach the container and open the lid without taking his eyes off a child and looking directly at the container.
    In an exemplary embodiment, the first depth, Dl, of the unitary dispensing partition 40 extends into the container in the Z direction for a distance of at least 5 mm. More conveniently, the first depth,
    9/16
    Dl, of the unitary dispensing partition 40 extends into the container in the Z direction for a distance between about 5 and about 15 mm.
    Typically, the dispensing opening 60 can be a continuous slot 65 that extends a distance in an X direction along the arc having two ends, 70, 75. The two ends 70, 75 of the continuous slot 65 are present in the arc 65 at a second depth, D2, in the Z direction which is less than the first depth, Dl.
    In exemplary embodiments, this allows the initiation of tearing to begin in the middle portion 90 of the scarf when the dispensing partition 40 makes contact with the rear edge 65 of the first scarf in the middle portion 90 of the scarf. The geometry of the arc that extends the depth of the container in the Z direction also provides improved control of the sheet separation dynamics during dispensing by providing separation in the Z direction of the orifice feature that initiates the hole tear and the point in the orifice where the scarf first emerges from the hole. The subsequent sheet is already gripped by the dispensing partition 40 in the middle of the sheet while tearing continues on the sides of the handkerchief. This helps to keep the subsequent sheet in the dispensing partition 40 for future dispensing and prevents the subsequent tissue from descending back into the container 10.
    Thus, the geometry of the dispensing partition 40 provides a unique check valve action which helps to prevent the posterior short parts of the subsequent tissue from descending back into the container. Conventional flexible holes are designed with all points on the orifice surface residing in the same place. Conventional flat holes do not provide separation in the Z direction or initiation of tearing and the initial appearance of the front edge of the scarf through the hole and therefore offer less control of the separation process.
    Alternatively, the tear initiation begins at the outer edge 61, 63 of the handkerchief of the dispensing partition 40, makes contact with the back edge 65 of the first handkerchief in the middle portion
    10/16 of the scarf. The subsequent sheet is already gripped by the dispensing divider 40 in the middle of the sheet while the tear continues towards the middle of the handkerchief. This helps to keep the subsequent sheet in the dispensing partition 40 for future dispensing and prevents the subsequent tissue from descending back into the container 10.
    Additionally, when drilling tearing is initiated at the upper corners of the inverted arch of the dispensing partition 40, the middle portion 90 of the front edge of the subsequent tissue has already passed through the orifice 60. This helps to ensure that when the separation is complete, the subsequent handkerchief is optimally arranged for the next dispensation.
    Thus, the container with the arc shaped dispensing hole has improved dispensing with fewer dispensing failures caused by handkerchiefs falling back into the container, handkerchief tears or multiple handkerchiefs being pulled from the container in a single pull. . The dispensing partition described here typically has a dispensing failure rate of less than 8%.
    As discussed above, the dispensing orifice 60 can be formed as a slit 65 in a dispensing partition 40 located under the lid top 15 which is formed from flexible or elastic material. The narrow slot 65 in the dispensing divider 40 can help to retain moisture in the wet wipe dispenser 10, firmly hold the exposed portion of the wet wipe in place, and make it easier to reach the wet wipe dispenser to retrieve the next wipe if the sudden projection functionality fails since the elastomeric or flexible material can be readily deformed and then return to its original shape. In addition, the narrow slit with a wet wipe protruding from the slit effectively closes the dispensing orifice 60, reducing any possible leakage of the wetting solution from the wet wipe dispenser when the wet wipe dispenser is inverted. The dispensing orifice 60 can be a slit having a sinusoidal middle portion with two legs extending in opposite directions from the middle portion as shown in Figure 1.
    11/16
    Alternatively, the dispensing orifice 60 may be of another size and / or shape such as circular, oval, rectangular, in the shape of H, in the shape of +, in the shape of a star or other suitable shape. Preferably, the dispensing hole 60 is restricted or reduced in size compared to a dispensing surface area of the wet wipe stack 50, as shown in Figure 1, to assist in separating successive wipes and retaining the wet wipes partially exposed to from the dispensing hole during vertical dispensing.
    Examples of flexible rubber-like materials used in the container of the present invention include thermoplastic elastomeric materials (TPE) that can be used to provide acceptable dispensing. Materials that can be employed include (but are not limited to): any of the styrenic-based TPE family (ie, styrenic block copolymer compounds); rubber modifiers containing styrenic-based TPE such as Kraton ™, Santoprene ™, or other rubber modifiers; special copolymers, such as methyl ethylene acrylate copolymers (for example, EMAC ™ from Eastman Chemical Company); thermal consolidation rubbers; polyurethane; alloys, amides; Engineering PTE, olefin-based vulcanized; olefinic vulcanized; polyester-based material; based on polyurethane. Such a rubber-like flexible sheet material could be that manufactured by the GLS Corporation of McHenry, Illinois and known as resin # G2701. The G2701 material is one of the resins in the TPEs product family. G27 01 is a styrenic based material and is in the family of copolymer compounds in styrenic block. Some specific properties of G2701 can be: specific gravity of 0.90 g / cm 3 (according to ASTM D792); hardness (Shore A durometer) of 68 (ASTM D2240); and 24% compression consolidation at room temperature; 96% at 70 2 C (according to ASTM 395B). Another similar material is known as G2755 and is also sold by GLS Corporation. In addition, a lubricant (for example, wax) can be added to decrease the coefficient of friction of the continuous crack that can benefit from injection molding, dispensing of wet wipes, and physical handling of the flexible orifice. G2701 TPE resin with wax additive
    12/16 to 0.25% sold by GLS Corporation and known as # LC217-189 can be used.
    The properties of the dispensing partition can be described in terms of hardness, stiffness, thickness, elasticity, specific gravity, compression consolidation, and any combination thereof. More specifically, the Shore A hardness (as measured by ASTM D2240) of the rubber-like sheet or flexible material can be about 100 or less, more specifically about 20 to about 90, and even more 10 specifically to from about 40 to about 80, and even more specifically from about 60 to about 70. The Gurley stiffness of the sheet or flexible rubber-like material (as measured by ASTM D 6125-97 Standard Test Method for Bending Resistance of Paper and Paperboard) can be about 15 10,000 milligrams of strength (mgf) or less, more specifically from about 100 to about 8,000 mgf, more specifically from about 200 to about 6,500 mgf, and even more specifically from about 300 to about 1500 mgf. The thickness of the rubber-like flexible sheet can be about 20 mg or greater, more specifically from about mg to about 110 mg and even more specifically from about 35 mg to about 60 mg. The elasticity of the rubber-like flexible material or sheet, as characterized by the 100% elongation tensile effort and measured according to 25 ASTM D412 Standard Test Methods for Vulcanized Rubber and
    Thermoplastic Elastomers, can be about 10 megapascals (MPa) or less, more specifically from about 0.1 to about 7 MPa, and even more specifically from about 0.5 to about 2.5 MPa. The flexible rubber-like sheet can have a density (according to ASTM D792) from about 0.80 to 1.21, more specifically from 0.88 to about 1.10, and even more specifically from about 0 , 90 to about 1.0. The flexible, rubber-like sheet can be compressed (according to ASTM 395B) (at room temperature / at 35 21,1 2 C (70-F)) from about 80/30 to 40/120 and more specifically from 15/45 to about 28/100.
    To allow access to stored tissues
    13/16 inside the container, the lid structure 12 includes a lid activation button 30. After the lid activation button 30 is pressed, the lid top 15 is released from the lid base allowing a user to access a opening into the container. The lid top 15 is secured in a closed position by means of a suitable lid engaging mechanism engaged with a button engaging mechanism. In exemplary embodiments, the lid engaging mechanism includes a projection latch on the front edge of the lid top 15 which is engaged by a button engaging mechanism including an opening stopper on the inner longitudinal edge of the lid activation button 30. In other exemplary embodiments, the lid latch mechanism includes a protrusion latch on the front edge of the lid top which is engaged by a button latch mechanism including a projection stopper on the inner longitudinal edge of the lid enable button 30. In still other embodiments, the lid engagement mechanism includes an opening stop at the front edge of the lid top 15 which is engaged by the button engagement mechanism including a projection latch on the inner longitudinal edge of the lid activation button 30.
    As used herein, stiffness means a level of hardness commonly associated with the materials used to manufacture containers containing wet wipes or parts thereof. Numerically, these materials typically have a flexural modulus (as measured according to ASTM D790 Standard Test Method for Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials) of at least 100 Newtons per square millimeter. In specific modalities, the cover activation button has a bending module of between 1,100 to 1,500 Newtons per square millimeter.
    In use, the top of the dispenser is opened and then access to the flexible orifice is obtained. The user then passes his hand through the continuous slot to take the first handkerchief from the handkerchief stack. If the hole is a frangible seal, it can be broken before the user can pass his hand through the hole. When the user grabs the tissue, it can then pass through the hole and out of the dispenser as per the user
    14/16 pull it up. If the user does not immediately need the tissue, it can be left in the partially dispensed hole where it can be held in place by the continuous slit until it is later desired. The partially dispensed tissue will only remain in place in the orifice, partially inside the dispenser and partially in the space between the top and the flexible orifice, conveniently ready for later dispensing in the form of a sudden projection. If the user wants to use the tissue immediately, he can pull the entire tissue through the continuous slit and out of the dispenser.
    Suitable materials for the wipes of the present invention are known to those skilled in the art. For wet wipes, these can be made of any material suitable for use as a wet wipe, including meltblown, coform, air-settled materials, carded bonded weft materials, hydraulically matted materials, high moisture resistant tissue paper, and the like and may comprise synthetic or natural fibers or combinations thereof. The wipes of the different aspects of the present disclosure can contain a liquid that can be any solution that can be absorbed in the wipes, thus making them wet wipes. The liquid contained in the wet wipes can include any suitable components that provide the desired wetting properties. For example, components can include water, emollients, surfactants, preservatives, chelating agents, pH buffers, fragrances, or combinations thereof. The liquid may also contain lotions, ointments and / or medications. The amount of liquid contained within each wet wipe may vary depending on the type of material being used to provide the wet wipe, the type of liquid being used, the type of container being used to store the wet wipe stack, and the end use. desired size of the wet wipe. Generally, each wet wipe can contain from about 15 to about 600% by weight and conveniently from about 200 to about 400% by weight of liquid based on the dry weight of the wipe for improved cleaning.
    Consequently, the different aspects and characteristics of the present invention can provide containers for
    15/16 handkerchiefs which, when compared to conventional handkerchief containers, provide improved storage and container dispensing. Such containers are particularly useful for dispensing baby wipes since the caregiver typically has only one hand free during the dispensing process. The packs for the wipes, for example, baby wipes, of the present invention are opened safely and easily by one of the user's or caregiver's hands for improved convenience and personal hygiene since the wipe is more likely to be in the dispensing divider 40. In addition, the packages of the present invention can provide more consistent, better dispensing.
    EXAMPLE
    The performance of the dispensing partition in the arc format can be measured more directly, by demonstrating the dispensing consistency of the dispenser. To illustrate the improved dispensing partition, the dispensing through the arc shaped dispensing partition has been compared with a conventional flat dispensing partition.
    To determine dispensing efficiency, containers as described herein have been tested including containers with an arc shaped dispensing partition and containers with a flat dispensing partition. Three separate stacks of 42 KLEENEX® COTTONELLE FRESH® Folded Tissues (commercially available from Kimberly-Clark Corporation of Neeneh, WI) were manually pulled from the containers to calculate a dispensing failure rate. The separate handkerchief stacks included three clips (clips) or sets of 14 handkerchiefs connected by perforations, with each subsequent comb connected by an adhesive. A layoff failure is defined as a tear, a return fall, or a multiple run. A tear is a handkerchief being torn as it is pulled through the partition. A fall back is the subsequent handkerchief descending back into the container. A multiple run is defined as more than a single handkerchief being pulled from the container with a single pull. Whenever any of these actions occurred it was considered a failure of
    16/16 dismissal. The percentage of dispensing failures is calculated as a number of dispensing failures divided by the number of tissues in the stack.
    Table 1: Dismissal Failure Rates
    Arc Shaped Dispensing Partition Flat Dispensing Partition Experiment No. 1 Failure Rate (%) 5.2 10.3 Experiment N ° 2 Failure Rate (%) 5.2 12.7 Experiment N ° 3 Failure Rate (%) 6.7 12.3 Average Failure Rate (%) 5.70 11.76
    Table 1 illustrates that containers having an arc shaped dispensing partition as defined herein have fewer dispensing failures than containers having flat dispensing dividers. The arc shaped dispensing partition is shown to have a dispensing failure rate of about 5.7%.
    Although the container useful for the purposes of the present invention has been specifically illustrated in the figures, those skilled in the art will consider that many different models of containers are possible, including 15 can containers, without departing from the scope of the invention.
    It will be considered that the preceding description, provided for the purpose of illustration, should not be considered to limit the scope of the present invention, which is defined by the following claims and all their equivalents.
