    FIELD OF THE INVENTION
    [001] The present invention relates to a trigger cap or spray head for a liquid container that allows the contents of the container to be sprayed without the cap being removed. The invention is of use mainly in the field of home medical care and personal care where it can be used as part of a product dispenser in the form of a manual aerosol. A characteristic aspect of the invention is that the spray head allows the dispenser with which it is associated to be converted interchangeably between the operational and inoperative states. BACKGROUND OF THE INVENTION
    [002] Sprayable liquid sprays by means of actuation caps that allow the conversion between the operational and inoperative states, optionally for use with pressurized liquid containers, have already been described in the state of the art.
    [003] International patent application WO 2004/078635 (Seaquist) discloses a trigger for an aerosol dispensing valve that comprises a rotary trigger button between a locked position and an unlocked position.
    [004] European patent application EP 1,040,055 B1 (Unilever) discloses a spray head comprising a rotating top cap between a first position in which a drive is possible and a second position in which a drive is not possible.
    [005] United States patent application US 4,542,837 (Metal Box) discloses a driver that has rotating parts, upper and lower, which can be rotated between the operating position and the inoperative position.
    [006] European patent application EP 2,049,415 B1 (Valois) discloses a liquid dispensing head that comprises a driving means for driving a push button in axial displacement with respect to the valve stem, the push button being used to fire the act of dispensation.
    [007] International patent application WO 07/120570 (Precision Valve) discloses a locking aerosol product dispenser with a dome attached to a base locking member and also attached to an ovoid product application valve assembly spray from an aerosol dispensing can. DESCRIPTION OF THE INVENTION
    [008] It is an objective of the present invention to provide a robust and yet ergonomically attractive means of spraying liquid products, especially products intended for application on the surface of the human body.
    [009] The invention is especially suitable for applying cosmetic products to the surface of the human body, especially in the armpit areas of the human body.
    [010] In a first aspect of the present invention, there is provided: a spray head suitable for use with a container of aerosol-shaped material comprising a central valve stem, said spray head comprising: 1. A chassis capable of standing firmly attached to the ovoid part of the valve of an aerosol product container, said chassis comprising a circular platform and a peripheral skirt; 2. A rotating circular collar located around and largely on the peripheral skirt of the chassis, said collar comprising a bridge that covers the diameter of the collar; 3. A spray channel and trigger button associated with it, said spray channel being designed to pass through a central opening in the circular platform of the chassis and through a central opening in the bridge that covers the diameter of the collar, and being possible to connect to the central valve stem of an aerosol product container with which the spray head is designed to be used; and 4. An upper body designed to fit over the chassis and the spray channel, the upper body defining a first opening, optionally covered by a flexible membrane, located on the trigger button associated with the spray channel and a second opening involving the end of the spray channel in such a way as to allow a product to pass from an outlet at the end of the spray channel to the outside; the body holding the spray channel and the associated trigger button in a non-rotating manner and the collar being rotatable between a first position in which the spray channel is unable to be pressed and a second position in which the spray channel is capable of be pressed when pressure is applied to the associated trigger button.
    [011] In a second aspect of the present invention, a method is provided for applying a cosmetic composition to the surface of the human body comprising the use of a spray head according to the first aspect of the invention.
    [012] The spray head of the present invention is designed for use with a product supply in liquid form, mainly with a liquid cosmetic composition to be used on the surface of the human body. The liquid product is supplied from a container to which the spray head is connected.
    [013] The spray head is especially suitable for use with a pressurized aerosol canister containing the product to be dispensed.
    [014] A fundamental aspect of the invention is that the spray head can be easily switched between a first position in which it is inoperative and a second position in which it is operative; that is, between a first position in which the spray channel cannot be pressed and a second position in which the spray channel can be pressed. This change is made not by means of a component that the operator uses to activate the spray head, but by means of a rotating collar that the operator manually rotates to switch the device between inoperative and operational state.
    [015] Another benefit of the present invention is that the spray channel, typically the most fragile element of spraying through lids, is always strongly attached and surrounded by the chassis and the upper body respectively. In addition, the spray channel does not need to move in preparation for activation.
    [016] The spray channel, which is connectable to a central valve stem of an aerosol product container with which the spray head is designed to be used, passes through both a central opening in the circular chassis platform and a central opening in the bridge that covers the diameter of the collar. This central double support of the spray channel avoids any lateral pressure “during use” on the valve of the aerosol container with which the spray head is designed to be used. Most importantly, this mechanical interaction between the three essential components of the spray head and the valve stem of the associated aerosol product container, provides great strength and resistance to the assembly “during use”.
    [017] In this patent application, the terms of guidance such as "top" and "bottom", "top" and "bottom" must be understood as referring to the spray head in the position it would occupy when in normal use sitting on the top of a can of aerosol product oriented in the vertical direction with which it was designed to be used, as illustrated in Figure 1, for example.
    [018] When the outlet channel of the spraying channel has an outlet arranged radially, the "front" of the spraying head must be understood to be in the same radial direction as said outlet outlet. By analogy, the “rear” of the spray channel must be understood to be in the opposite radial direction. The “sides” of the spray head should be understood as being “faces” in a radially orthogonal position in relation to the front to the rear axis.
    [019] In this document, the term “central” is used with reference to a plane orthogonal to the “long” axis that runs from the top to the bottom of a vertically oriented aerosol can with which the spray head is designed to be used. It should also be understood as referring to that spray head plane as a whole, and not to any specific component thereof.
    [020] In this document, the term “main axis” should be understood as being the “long” axis from the top to the bottom of a vertically oriented aerosol can with which the spray head was designed to be used and the axis from top to bottom of the spray head itself.
    [021] In this document, the term "largely" should be understood as meaning predominantly.
    [022] The bridge covering a diameter of the collar does not need to be a single element and does not need to connect directly to the extreme radial edges of the collar. In preferred embodiments, the bridge crosses the collar at the upper end of it. It is still preferable that the bridge rests against a section that protrudes from the top of the circular platform of the chassis, said section that protrudes limiting the rotational movement of the collar because of its interaction with the bridge that is there. However, it is essential that the collar maintains the ability to rotate between a first position in which the spray head is inoperative and the bridge preferably abuts a second edge of a section that protrudes from the top of the circular platform of the chassis .
    [023] In preferred embodiments, the spray head comprises a fourth essential component: an upper body designed to fit over the chassis and the spray channel, the upper body defining a first opening, optionally covered by a flexible membrane, located on the trigger button associated with the spray channel and a second opening that surrounds an outlet of the spray channel in order to allow the passage of a product from the spray channel to the outside.
    [024] In preferred embodiments, the spray channel comprises a central vertical segment, connectable at its lower end to a valve stem of an aerosol can and connecting its upper end to a segment that protrudes radially outwardly. the central segment. In such embodiments, the central segment is in connection with liquid with the segment that protrudes radially outward from there and also with the valve stem, when connected there. The segment of the spray channel that protrudes radially outward does not need to be in the plane orthogonal to the main axis of the spray head, but it does need to have a component of its projection in said plane.
    [025] The spray head components are typically made of plastic material. The chassis can be made of polypropylene, as well as the spray channel and the upper body, when present. When the upper body has a flexible membrane covering a first opening located on the trigger button associated with the spray channel, it is typically made of a thermoplastic elastomer.
    [026] The features described with reference to the following specific embodiment can be considered preferred features of the generic description given above and / or can be incorporated independently into the subject as described by the following claims. BRIEF DESCRIPTION OF THE DRAWINGS
    [027] Figure 1 is an angled view of the spray head 1 from the top, together with a partial view of an associated can of aerosol product 2.
    [028] Figures 2 and 3 are angled views of a spray head chassis 1 from above and from below, respectively.
    [029] Figures 4 and 5 are angled views of a rotating circular collar 4 of the spray head 1 from above and from below, respectively.
    [030] Figure 6 is a view of a spray channel 8 and the associated elements of the spray head 1.
    [031] Figures 7 and 8 are seen of an upper body 42 of the spray head 1 from above and below, respectively. DESCRIPTION OF ACCOMPLISHMENTS OF THE INVENTION
    [032] Figure 1 illustrates the spray head 1 seated on top of a vertically oriented aerosol product can 2 shown partially with which it is designed to be used. The characteristics of the spray head 1 that can be seen partially are a chassis, a rotating circular collar 4, and an upper body 5 that defines a front opening 6 through which an outlet 7 at the end of the spray channel 8 can be seen. The upper body 5 also defines an upper opening 9 covered by a flexible membrane 10 and two lateral openings 11, one of which can be seen in Figure 1, which reveals the chassis underneath.
    [033] Figures 2 and 3 illustrate the chassis in greater detail. It can be seen that the chassis has a circular platform 12 that extends through its central region punctuated by a central opening 13 and that there is a circular wall 12A that depends on its edge. The chassis also has a peripheral skirt 14 around its circumference. The upper edge of the peripheral skirt 14 is separated from the lower edge of the circular wall 12A dependent on the circular platform 12 by an annular platform 14A.
    [034] Projecting upwards from the circular platform 12 are two sections 15 which are diagonally opposite on each side of the central opening 13. Between these two projected sections 15, a bridge 16 of the rotating collar 4 rests on the surface top of them when the spray head is fully assembled see below. The inner surface 15A of each of these projected sections 15 is shaped like the inner surface of a tube having its central axis as the main axis of the spray head 1 and each having the same radius of curvature. Each inner surface 15A has a guide groove 17 between each of the two inner projections 18 from said inner surface 15A. The guide grooves 17 are diagonally opposite on both sides of the central opening 13 and are designed to accommodate wing elements 19 projecting from a central vertical segment 20 of a spray channel 8 see below. The interaction between the guide grooves 17 in the chassis and the wing elements 19 of the spray channel 8 serves to restrict the rotational movement of the spray channel 8 in relation to the chassis.
    [035] The outer surface 15B of each of the projected sections 15 is an extension of the circular wall 12A at the edge of the circular platform 12.
    [036] Figure 2 also illustrates three peripheral projections 22A, 22B, and 22C arched equally spaced in circumference around the upper edge of peripheral skirt 15. One of these projections 22A is located towards the rear of collar 4 and is not it overlaps radially over the projected sections 15. The other two projections 22B and 22C are arranged radially at 120 ° with respect to the first 22a and do not overlap radially over the projected sections 15.
    [037] Each of these projections 22A, 22B, and 22C has a fillet 23 on its outer surface near its upper end designed to interact with the rotating collar 4 and limit axial movement between the chassis, the rotating collar 4 and the body higher 42 see below.
    [038] The peripheral projections 22A, 22B, and 22C are connected to the circular platform 12 by connecting walls 24 that run from their radial ends to the circular wall 12A depending on the circular platform 12. For the two peripheral projections 22B and 22C that are overlap radially over the projected sections 15, the connecting walls 24 also connect to the external surface 15B of the projected section 15. These two peripheral projections 22B and 22C each have an arched platform 22D that partially runs from the inner surface to the outer surface 15B of the projected section 15. These arched platforms 22D form the top surface of each peripheral projection 22B or 22C of which they are a part, in addition to a short wall 22E that extends upwards on the outer edge of the peripheral projections 22B and 22C . The short walls 22E each carry one of the aforementioned threads 23 on its outer surface and each has struts 22F on its inner surfaces. Similar, but longer, struts 22G exist on the inner surface over a wall 22a that extends upwards on the outer edge of the peripheral projection 22A that does not overlap radially with the projected sections 15.
    [039] Figure 3 shows that the chassis has an inner skirt 24 located somewhat inside the peripheral skirt 15 and connected at that point by numerous support bridges 25 some of which are labeled.
    [040] The inner skirt 24 has an annular valve core fixing thread 26 around its inner surface near its lower end designed to hold the body tightly and non-rotationally to the valve core of an aerosolized product can with which spray head 1 is designed to be used.
    [041] Figure 3 also illustrates that the bottom surface of the circular platform 12 of the chassis 3 has several strengthening struts 27 some of which are labeled which serve to increase the robustness of the spray head 1.
    [042] Figures 4 and 5 illustrate characteristics of the rotating circular collar 4 in more detail. Collar 4 has a beveled outer wall 28 that bears a double-headed arrow graph pointing right and left 29 to indicate to the user that collar 4 is rotatable. Attached to the outer wall 28 at its top end by three bridge elements 30, radially equally spaced around the collar 4, there is a circular disc 31. The circular disc 31 is held somewhat above the top of the outer wall 28 by the elements of bridge 30 and designed to rest on the arched platforms 22D of peripheral projections 22B and 22C that overlap radially with the projected sections 15 of the chassis 3. The inner edge of the circular disc 31 abuts the outer surface 15B of each of the projected sections 15 and the outer edge is within walls 22E and 22H extending upwardly at the outer edge of peripheral projections 22A, 22B, and 22C.
    [043] Suspended from the circular disk 31 by connections 32 diagonally opposite there is a bridge 16, covering a diameter of the circular disk 31. The connections 32 support the main body of the bridge 16 at a height approximately level with the top of the outer wall 28.
    [044] The bridge 16 comprises an annular ring 32 in its center, through which a central vertical segment 20 of a spray channel 8 is designed to fit below. The bridge 16 was designed to rest on the circular platform 12 of the chassis 3 and to be rotated there between the limits imposed by the sections 15 that protrude from the circular platform 12. Projecting from the upper surface of the bridge 16 and bordering the rim ring ring are two truncated wedge elements 33.
    [045] The spray channel 8 shown in Figure 6 comprises a central vertical segment 20 and a radial segment 34 that slopes upward as it radiates outward. The radial segment 34 is terminated by an expanded section 35, which can accommodate a swirl chamber which is not shown and which has outlet 7 of the spray channel 8 at its end. The radial segment 34 has a strengthening strut 34A that protrudes upwards from its external surface.
    [046] The radial segment 34 is in liquid communication with the central vertical segment 20 which is itself in liquid communication with a valve stem from an associated can of aerosol product 2 which is not shown via a stem outlet valve 36 when the spray head 1 is in use.
    [047] The central vertical segment 20 has winged elements 19 that project radially outwardly from its side wall in opposite directions orthogonal to the radial direction of the radial segment 34 of the spray channel 8. These winged elements 19 are designed to fit into the guide slots 17 on both sides of the central opening 13 of the chassis 3 see above. The winged elements 19 extend outwardly from the lower region of the central vertical segment 20.
    [048] The central vertical segment 20 also has forward and backward projections 37 and 38, respectively from its side wall. The forward projection 37 has the same radial direction as the radial segment 34 of the spray channel 8 and the rear projection 38 projects outwardly in the opposite radial direction. The forward projection 37 has a T-shaped cross section at its lower end. The forward and backward projections 37 and 38, respectively, extend outwardly from the lower region of the central vertical segment 20, both ending at the same axial height at which the wing elements 19 orthogonal to them end.
    [049] At the upper ends there, the winged elements 19 project outward distinctly beyond, to give what could be called the upper winged extensions 19A.
    [050] Associated with the spray channel 8 at its top end is a trigger button 39 which curves down towards the rear and which is domed when viewed from above. On the underside of the trigger button 39 there are several strengthening struts, only two of which 40 and 41 are illustrated.
    [051] Sitting on all the other components of the spray head 1 there is an upper body 42 as illustrated in Figures 7 and 8. The upper body 42 defines a first opening 43 located on the trigger button 39 that is associated with the spray channel 8 and a second opening 44 surrounding the outlet 7 of the spray channel 8. The upper body 42 also defines two side openings 45 and 46 which provide the consumer with a view of the internal characteristics of the spray head 1.
    [052] The first opening 43 is covered by a flexible membrane 47 that has grooves 47A on its upper surface and is typically made of a thermoplastic elastomer.
    [053] The upper body 42 has a peripheral skirt 48 of circular cross section. This skirt 48 is superimposed on the three arcuate peripheral projections 22A, 22B, and 22C that extend the peripheral skirt 15 of the chassis 3 upwards. The peripheral skirt 48 of the upper body 42 has three inwardly projecting elevations 49 equally spaced around its bottom inner edge. One of these elevations 49 is illustrated in Figure 8. These three elevations 49 were designed to be fixed under the lugs 23 on the outer surface of each of the peripheral projections 22A, 22B, and 22C from the chassis 3 and thereby hold the upper body 42 and the chassis axially together.
    [054] The lower edges of the elevations projecting inwards 49 rest on the upper edge of the chamfered outer wall 28 of collar 4, but do not restrict the rotation of this piece.
    [055] Figure 8 illustrates two of three elevations 49A that project downward from the bottom of the inner surface of the upper body 42. These elevations that project downward 49A are radially aligned with the elevations that project inward 49 to from the peripheral skirt 48 of the upper body 42 and are designed to interact with the struts 22F and 22G on the internal surfaces of the walls 22E and 22H on the edges of the arched platforms 22 of the chassis 3 and thereby increase the robustness of the connection between the upper body 42 and chassis 3.
    [056] Other characteristics of the upper body 42 that can be seen in Figure 8 are two slots that project downwards 50 between projections 51 from the edge of the first opening 43 in the upper body 42, that is, the opening that is located on the trigger button 39. These grooves 50 are designed to accommodate the upper wing extensions 19A of the wing extensions 19 from the side wall of the central vertical segment 20 of the spray channel 8. This interaction between the upper body 42 and the spray channel 8 assists in good rotational alignment between these two units.
    [057] Another feature that helps the good rotational alignment between the upper body 42 and the spray channel 8 is a peripheral wall that projects downwards around the edge of the first opening 43 in the upper body 42 and the fact that the button driver 39 has the same shape as said opening 43.
    [058] The lower part of the upper body 42 also comprising three sets of two struts 53 some of which are illustrated in Figure 8. These pieces project inwardly from the peripheral skirt 48 and are positioned so as to interact with the connecting walls 24 that form the radial edges of the peripheral projections 22A, 22B, and 22C from the chassis and thereby prevent the rotation of the upper body 42 in relation to the chassis.
    [059] The activation of the spray head 1 and the release of the contents of its associated product can in the form of aerosol 2 is achieved by pressing the spray channel 8 by applying pressure on the associated trigger button 39. This can only be done when the collar 3 is rotated in such a way that the wedge-shaped elements 33 that protrude from the upper surface of the bridge 16 are not touching the underside of the forward and backward projections 37 and 38, respectively from the side wall of the central vertical segment 20 of the spray channel 8. In that position, the central vertical segment 20 of the spray channel 8 can be pressed down through the central opening 13 in the chassis and through the ring rim 32 in the center of the bridge 16 extending through collar 4, to apply pressure to the valve stem of an associated aerosol product can and thereby release the contents of that can through the spray channel 8.
    [060] The pressing of the spray channel 8, when the collar is rotated as described in the paragraph immediately above, is limited by the bottom parts of the forward and back projections 37 and 38, respectively and by the bottom parts of the winged elements 19 all leaning against the upper surface of the ring rim 32 on the central bridge 13 that covers the diameter of the collar 4. This feature further projects the valve stem of the associated aerosol product can. The forward and backward projections 37 and 38, respectively and the winged elements 19 all extend to the same depth in the downward direction of the central vertical segment 20 of the spray channel 8 to assist in this task.
    [061] When the pressure on the trigger button 39 is removed, a spring on the valve stem of the associated aerosol product can force the spray channel 8 to rise to its original position and the collar 3 can be turned back to the position in which the pressing of the spray channel is avoided by the protrusions 33 located on the upper surface of the bridge 16 which is leaning on the underside of the forward and back projections 37 and 38, respectively from the central vertical segment 20 of the spray channel 8.
