Description

YOUR RTI DOR PORTATI L AEROSOL Field of the invention The present invention concerns a portable aerosol dispenser, in particular a portable aerosol dispenser for supplying a cosmetic composition on the surface of the human body.

Background US 6, 398,082 discloses an actuator mechanism for a portable can in which a slider is movable by finger pressure from an uncoupled valve position to a valve engageable position and a hidden spring returns the slider to a valve uncoupled position when Finger pressure is removed.

BRIEF DESCRIPTION OF THE INVENTION An object of the present invention is to provide an ergonomically excellent aerosol dispenser with a slidable actuator button.

In a first aspect of the present invention, an inductive portable aerosol dispenser is provided comprising an aerosol container and a sprinkler attached through the cap, the container having a valve at its top and a section acintada toward its end upper, the upper expansion of the section acinturada continues smoothly towards the lid attached, the lid attached that reaches a maximum cross-sectional dimension, which decreases more towards above, the joined lid reaching a maximum transverse dimension, which decreases further upwards and having: (i) an actuator button located on its surface above its maximum transverse dimension, said button being angled upwards from 15 ° to 50 °; (ii) a sprinkler opening on the opposite side of the cap of the actuator button; Y (iii) an associated sprinkler channel that provides a fluid connection between the valve in the container and the sprinkler opening; the dimensions of the spout allow the consumer to hold the spout around the hinged section of the container and, with the same hand, press on the actuator button with an index finger to operate the spout.

In a second aspect of the present invention, there is provided a method for applying an aerosol cosmetic composition to the human body comprising the use of an actuator according to the first aspect of the invention.

Detailed description Throughout this description, the terms of orientation such as "top", "top", "vertical", "horizontal" and "down" should be understood as referring to the spout in its "straight" position with the base of the container seated on a horizontal surface.

The term "depends" should be understood as referring to characteristics that project downwards from others.

The term "lateral" should be understood as referring to the plane approximately orthogonal to the vertical axis of the spout when oriented as described in the paragraph before the latter.

The vertical axis of the spout can be thought of as its main axis and the term "horizontal" refers to the plane orthogonal to this axis.

The dispenser of the present invention is easy to operate using only one hand. The angled actuator button and the shaped design of the container allow the dispenser to be held conveniently in the hand with the index finger capable of operating the actuator via a simple extension action. Desirably, the spout is dimensioned so that the consumer can hold the waist of the container between the ball of his thumb and his third and fourth fingers and have his index finger in a slightly bent position when his finger pad is placed in the center of a finger pad on the top of the actuator button before the drive.

The top surface of the actuator button should be considered the finger pad of the actuator button.

The acintada section of the container should be understood as a narrow section with a smooth contour. That is, a section of diameter gradually decreasing towards the "waist", followed by a section of gradually increasing diameter. The "waist" should be understood as the narrowest part of the section acinturada.

The "upper" part of the pump should be understood as the of the spout above your waist and the "bottom" part of the spout should be understood as the part of the spout below your waist.

The shaped section of the container is normally present as part of the upper half of the container and preferably as part of its upper third.

The upper expansion of the acted section continues smoothly towards the sprinkler attached through the lid. That is, the upward expansion of the spout diameter continues to approximately the same degree as it moves from the container to the cap. This does not exclude the possibility of a clear connection between the container and the lid through the sprayer; Actually, this is normal (vide infra). Preferably, the maximum diameter of the upper part of the spout is at the point where the cap through the sprayer fits over the container.

For reasons of stability, the maximum diameter of the upper part of the spout preferably is not greater than the maximum diameter of the lower part of the spout. More preferably, the diameter of the top of the spout is the same or approximately the same as the diameter of the bottom of the spout.

In preferred embodiments, the cap through the sprinkler is insurable in place at the top of the aerosol container. This can be achieved by means of ridges around the lower inner edge of the lid through the sprinkler and a slot associated with the upper part of the aerosol container. By having the cap through "secured" sprinkler in place on top of the container spray, operational robustness is improved. The cap through the sprinkler is a lid through which the product in the aerosol container can be dispensed (sprayed) without being removed. This is achieved by having an associated sprinkler channel that provides fluid communication between the valve over the container and the sprinkler opening in the sprinkler cover.

The sprinkler opening is an opening defined by an outer wall of the lid through the sprinkler. Through this opening, the sprinkler channel allows the contents of the container to be dispensed when the valve in the container is opened. The sprayer opening will be considered to be in front of the spout.

The valve in the container can be opened by pressing down on it, normally generated by pressing down on the associated sprinkler channel.

In preferred embodiments, the waist of the container has an outer diameter from 30 mm to 40 mm, more preferably from 33 mm to 39 m, and most preferably from 35 mm to 37 mm.

In preferred embodiments, the waist of the container is located from 70 mm to 90 mm, more preferably from 75 mm to 81 mm, and most preferably from 77.5 mm to 79.5 mm from the center of the finger pad of the actuator button measured as the minimum distance along the curved outer surface of the spout. These dimensions are particularly suitable when the spout is to be used by women, the resulting spout being well adjusted to the typical female hand and being particularly easy to use.

In preferred embodiments, the ratio of the outer diameter of the waist of the container to the distance between the outside diameter of the waist and the center of the finger pad of the actuator button, measured as the minimum distance along the curved outer surface of the spout, is at least 0.42 to 1 and not greater than 0.50 to 1, more preferably being at least 0.44 to 1 and not greater than 0.48 to 1, and most preferably being at least 0.45 to 1 and not more than 0.47 to 1. These dimensions are particularly suitable when the spout is to be used by women, the resulting spout being well adjusted to the typical female hand and being particularly easy to use.

In preferred embodiments, the ratio of the outer diameter of the waist of the container to the diameter of the container at the point where the cap through the sprayer fits over the container is at least 1 to 1 .15 and no greater than 1 to 1. 35, more preferably being at least 1 to 1.2 and not more than 1 to 1.3 and most preferably 1 to 1.25. These relative dimensions, in particular in combination with one of the preferred proportions detailed in the previous paragraph, lead to enhanced ergonomic benefits.

The actuator button is preferably operated by sliding it; sliding the actuator button forward causes the contents of the aerosol container to be released via the sprayer opening. The sliding of the button can be conveniently done by extending an index finger when said finger is in a slightly bent position with the finger pad seating from the center of the actuator button.

For repeated use, it is highly preferred that the actuator button has a return mechanism. Normally, the actuator button is adjusted with a return spring that is energized when the button is pushed forward and serves to return the button to its original position when the pressure on the button is removed.

The actuator button is at an angle from 1 5 ° to 50 °, preferably 20 ° to 45 °, and more preferably 25 ° to 40 °, to the horizontal. These angles should be considered the angle between the actuator button along its front-rear axis and the horizontal line in the same vertical plane. When the actuator is curved, it is required that there is a tangent to the curve at the indicated angle.

The actuator button may have ribs running through its upper surface in order to increase grip. Preferably, the upper surface of the button is made of a thermoplastic elastomer for the same reason. The main body of the actuator button can be made of an alternative plastic material, for example, an acetal co-polymer.

The actuator button, in particular the finger pad thereof, is preferably curved upwards at its front end. This serves to assist the forward sliding of the button and can thus contribute to the ergonomic advantages of the invention.

The release of container contents is normally via a sprinkler channel leading from a valve to the top of the container to the sprinkler opening. In preferred embodiments, when the actuator button is slid forward, it is possible to downward pressure to be exerted on the valve, thereby opening said valve and allowing the pressurized aerosol composition within the container to be dispensed.

In preferred embodiments according to the preceding paragraph, the actuator button is slid forward and then downward in order to exert downward pressure on the valve at the top of the aerosol container. Preferably, it is achieved via a projection depending on the actuator button exerting downward pressure on the sprinkler channel, which in turn exerts pressure under the valve.

The cap through the sprinkler, including the associated sprinkler channel is usually made of plastic, such as polypropylene. A typical manufacturing method is injection molding.

The aerosol container used in accordance with the present invention is usually made of tinplate or aluminum. The valve is located in the upper part of the container, usually in a central position. The container is capable of withstanding the pressure of the aerosol composition stored inside. This pressure can be up to 2x105 or 3x105 Pa (2 or 3 bar), up to 10x105 Pa (1 0 bar) or even up to 14x105 Pa (14 bar).

The aerosol container preferably contains a cosmetic composition for application to the surface of the human body. With such use and such compositions the ergonomic benefits of the present invention are particularly advantageous, the spout being particularly suitable for spraying products into the body itself. user. This is especially true for spray products normally focused towards the armpit areas, ie deodorant and antiperspirant compositions.

The features described with reference to the following specific embodiment can be incorporated independently into the generic description given above and / or as given in the claims.

Figure 1 1 is a section through the cap through sprayer (2) along B-B.

Figure 12 is a section through the cap through sprayer (2) along C-C.

Figure 1 3 is a front / side view of the sprinkler channel (15).

Figure 14 is a front / side view of the actuator button (6) from slightly below.

With reference to Figures 1 to 3, the aerosol container (3) has a tapered section (4) towards its upper end. The upper expansion of the aclined section (4) of the aerosol container (3) continues smoothly towards the lid through the attached sprinkler (2), although there is a clear union (5) between the two.

The cover through sprinkler (2) has a sliding actuator button (6) present on its surface above its maximum transverse dimension and on the opposite side thereof, there is a sprinkler opening (7) defined by a side wall (8) from the lid through the sprinkler (2).

The spout (1) is designed for maximum ease of handling, especially by the female hand. The slanted section (4) can easily be held between the ball of the thumb and the third and fourth fingers and when held in such a manner, the pad of the index finger of the same hand of the user can rest on the actuator button (6) with the index finger in a slightly bent position, ready to extension forward and upward.

In this specific embodiment, the ratio of the outside diameter of the container waist (3) to the distance between the outer diameter of the waist and the center of the actuator button (6), measured as the minimum distance along the outer surface dispenser curve is 0.46 to 1.

The cover through sprinkler (2) and features thereof are further illustrated in Figures 4 to 12. The cap through sprinkler (2) has a circular cross section, defined by the side wall (8), the diameter from the cover through the sprinkler (2) decreasing toward its upper end. The side wall (8) defines an oval sprayer opening (7), which is to be considered in front of the spout (1). The oval sprayer opening (7) has its short axis in the horizontal direction and is located towards the upper end of the side wall (8).

Projecting into the side wall (8) on either side of the atomization aperture (7) are two support wings (9). These support wings (9) are thin walls that extend from the top of the side wall (8) to a point about half their length. From the side of each of the support wings (9) facing the sprayer opening (7), a sprinkler channel guide wall (10) is projected. These sprinkler channel guide walls (10) are in a vertical plane orthogonal to the front-rear axis (A-A) of the spout (1). They extend from the support wing (9) towards one another in the vicinity of the sprinkler opening (7). The sprinkler channel guide walls (10) end up leaving a lid between them, which is always slightly larger than the short axis of the oval sprayer opening (7).

At the bottom of the side wall (8), there is a flange (1 1 A and 1 1 B) which is intended to allow the cover through the sprayer (2) to be clicked on the upper part of an aerosol container (1). ). The flange consists of six soft flanges (1 1 A) equally distributed around the lower interior surface of the side wall (8) and interspersed by corrugated flange (1 1 B). The detailed cross sections of the flange (1 1 A and 1 1 B) are illustrated in Figures 8 and 9, respectively. The flange snaps into an indentation (12) around the top of the aerosol container 1 (see I Figure 3).

The cover through sprinkler (2) also has a top wall (1 3) defining an opening (14); it being intended that the aperture accommodate a second of an associated sprinkler channel (15) (vide infra). The upper wall (1 3) is connected to the side wall (8) by an interior wall (16) that varies in height from the front to the rear, being relatively high at the front and decreasing toward the rear.

The upper wall (13) has a larger segment (13A) which is angled upwardly towards the front of the actuator at an angle of approximately 32 ° from the horizontal and a smaller segment (1 3B) which is approximately horizontal. (See Figure 1 1). The minor segment (13B) is present at the front end of the upper wall (13). The opening (14) in the upper wall (13) is centrally located where the major (13A) and minor (1 3B) segments meet, but it is mostly defined by the latter.

On either side of the opening (14), ie, in a direction orthogonal to the direction of movement of the actuator button (6), two projections (17) are raised from the minor segment (1 3B) of the upper wall (1 3 ). The projections (17) each have a raised edge (1 8) on their side adjacent the opening (14).

A mostly circular opening wall (19 and 20) aligns the opening (14) and depends as much on how it rises from the upper wall (13) in a vertical direction. (See Figure 12). The lower segment (19) depending on the upper wall (13) is longer than the upper segment (20) that rises from the upper wall (1 3). The lower segment (19) which depends on the upper wall (13) has a gap (21) towards the sprinkler opening (7). These additionally parallel walls (22) have smaller edges (23) that are inclined upwards in the direction of the sprinkler opening (7). The additionally parallel walls (22) terminate the level with the outer edge (24) of the inner wall (16).

The upper segment (20) of the opening wall that emerges from the upper wall (13) adjoins the above-mentioned projections (17) that also arise from the upper wall (13). From the upper segment front (20), a raised vault (25) extends, connecting the upper segment (20) to the inner wall (16) and bridging a "gap" in the smaller segment (1 3B) of the upper wall (13) and the upper segment (20) of the opening wall. The raised vault (25) is bulged in its upper part and its internal faces (26) are contiguous with the internal faces of the additionally parallel walls (22) extending from the edges of the gap (21) in the lower segment (19) of the opening wall depending on the upper wall (1 3). The raised vault (25) is designed to accommodate a segment of the sprinkler channel (1 5) (vide infra).

The inner face (20C) of the mostly circular opening wall (19 and 20) is contiguous and has vertical recessions (20D) on either side aligned with the two projections (17) arising from the upper wall (13) on either side of the opening (14).

For the largest segment (13A) of the upper wall (13), a central projection (27) rises and has a rear face (28) extending through a gap (29) in the upper wall (13). This extensive rear face (28) forms a substantial flange wall and will be referred to as such subsequently.

Towards the rear of the major segment (1 3A) of the upper wall (1 3), restriction clips (30) are projected. These are intended to restrict a segment of the actuator button (6) (vide infra). The clips (30) are seated on parallel grooves (31) in the upper wall (13) that extend rearwardly of the restriction clips (30) - that is, in the direction away from that in which the actuator button ( 6) is pushed.

Two additional parallel slots (32) are present in the larger segment (1 3A) of the upper wall 81 3). These additional parallel slits (32) also run from the front to the rear and are located on either side of the central projection (27), which extends from immediately behind the projections (17) that rise from the upper wall (1 3) to a point level with the rear face (28) of the central projection (27).

The aforementioned sprinkler channel (1 5) is illustrated in Figure 13. It is comprised of a vertical segment (33) and a segment (34) at an angle of approximately 1 14 ° to the vertical segment (34), i.e. 24 ° from the horizontal. The vertical segment (33) and the angled segment (34) are in fluid connection.

The vertical segment (33) of the sprinkler channel (15) is designed to fit over a valve stem (not shown) of the aerosol container (3) and is burned in its base (36V) to assist in such adjustment. The vertical segment (33) of the sprinkler channel (1 5) is also designed to be snapped into the opening (14) in the upper wall (1 3) of the lid through the sprinkler (2) (vide supra) . In this way, the lateral movement of the sprinkler channel (15) is restricted. The vertical segment (33) of the sprinkler channel (1 5) has a resilient area (35) on its upper part on which a segment of the actuator button (6) presses when the spout (1) is operated.

The vertical segment (33) of the sprinkler channel (15) has a vertically oriented oblong block (33A) projecting from either of its sides, ie, in a direction orthogonal to the direction of movement of the actuator button (6). These oblong blocks (33A) are designed to be able to slide within the vertical recesses (20D) on the inside face (20C) of the mostly circular opening wall (19 and 20). By such means, the movement Rotational channel of the sprayer (1 5) is restricted.

The vertical segment (33) of the sprinkler channel (1 5) has two small retaining clips (33B), each one present a little above the oblong blocks (33a) on either side thereof. These clips (33B) serve to hold the sprinkler channel (1 5) in place during manufacture and leave the path at the first use of the spout.

The angled segment (34) of the sprinkler channel (1 5) is narrower than the vertical segment (33), both internally and externally. The angled segment (34) leads from the upper part of the vertical segment (33) to the sprinkler opening (7). At the sprinkler opening end of the angled segment (34), there is an oval disc (36D), designed to fit just behind the oval sprayer opening (7) and leave no visible gap from the outside at any time. It is also a conventional swirl chamber (37) at the end of the angled segment (34), designed to improve sprinkler quality.

The actuator button (6) is illustrated in Figure 14. It is comprised of a finger pad (38) and several dependent characteristics thereof. The finger pad 38 is longer in the front-rear direction, i.e. the direction in which it is designed to slide. The finger pad is designed to sit on the top wall (1 3) of the lid through the sprinkler (2). The finger pad (38) curves upward at its front end (39) in order to increase the ergonomics of use. There are also curved projections (38A) on its upper surface for this same purpose. (See Figures 1 and 3 for these characteristics).

Vertically dependent on the finger pad (38) are two orientation clips (40) that are designed to pass through the two parallel slots (32) that are present in the largest segment (13A) of the top wall (1 3 ) located on either side of the central projection (27). The clips (40) have outwardly facing wedges (41) that help insert them into the slits (32), the clips (40) temporarily bend inwards when it is made. When the actuator button (6) is pressed, the retaining clips (40) slide forward within their respective slits (32).

Depending on the finger pad (38) along its central front-rear axis it is a structure configured as a keel (43). Said structure tilts outwardly from the underside of the finger pad 38 near its front end and terminates approximately halfway along the length of the finger pad 38. The lower part (44) of the keel-shaped structure (43) is designed to press down the resilient area (35) on the upper part of the vertical segment (33) of the actuator button (6) when the dispenser (1) it is operated.

A resilient blade spring (45) is dependent on the finger pad (38) at a point toward the rear of its front-rear axis. The spring leaf (45) is positioned to pass through the gap (2) in the upper wall (13) of the lid through the sprinkler (2) that exists behind the central projection (27) that emerges from said upper wall (13). The leaf spring (45) is designed to bear against the substantial support wall (28) which forms the extended rear face (28) of the central projection (27) emerging from the upper wall (13). When the actuator button (6) is pushed forward, the leaf spring is energized. When the actuator button (6) is released, the leaf spring (45) pushes the actuator button (6) back to its original position.

From the front of the finger pad (38), two projections (46) that are designed to interact with the two projections (17) rise from the smaller segment (1 3B) of the upper wall (1 3) of the lid depend through the sprayer (2). When the actuator button (6) is pushed forward, the lower part of the projections (46) depending on the finger pad (38) slides along the upper part of the projections (17) that raise the top wall (13) of the lid through sprayer (2) until said dependent projections (46) have passed said elevation projections (17). The raised edges (18) on the projections (17) that rise from the upper wall (13) of the lid through the sprinkler (2) serve to guide the projections (46) that depend on the finger pad (38) during this process. When said dependent projections (46) have passed said elevation projections (17), the actuator button (6) may be depressed.

From the back of the finger pad (38), depend two struts (47) carrying hinge joints (48) which are designed to fit in the parallel slits (31) located towards the part Rear of the larger segment (13A) of the upper wall (1 3) of the cover through the sprinkler (2).

When the actuator is operated, the actuator button (6) is slid forward and the projections (46) depending on the front part of the finger pad (38) pass next to the projections (1 7) that rise from the segment smaller (13B) of the upper wall (1 3) of the lid through the sprinkler (2). Simultaneous to this, the two orientation clips (40) depending on the finger pad slide forward within the two parallel slits (32) that are present in the larger segment (13A) of the upper wall (1 3) located on either side of the central projection (27) and the hinge links (48) depending on the back of the finger pad (38) slide along the parallel slits (31) located towards the rear of the segment greater (1 3A) of the upper wall (13) of the cover through the sprinkler (2). At the same time, the leaf spring (45) becomes energized when pressed against the support wall (28).

When the projections (46) depending on the front part of the finger pad (38) have slid past the projections (17) that rise from the minor segment (1 3B) of the upper wall (13), the actuator button (6) is able to be depressed. At this time, the hinge links (48) depending on the back of the finger pad (38) have reached the restriction clips (39) located toward the back of the larger segment (1 3A) of the upper wall. (13) The finger pad (38) is depressed in the structure with keel-shaped (43) dependent on it exerts pressure on the resilient area (35) in the upper part of the vertical segment (33) of the sprinkler channel (15). This causes the sprinkler channel (15) to press down on the valve stem (VS) of the container (1) on which it sits, thereby opening the valve and allowing the product to be discharged into the container (1) . During the depression of the vertical segment (33) of the sprinkler channel (1 5), the angled segment (34) of the sprinkler channel (1 5) slides down into the dome (25) that links the upper segment (20). ) from the opening wall to the inner wall (16) and the oval disc (36) at the end of the sprinkler channel (1 5) slides down just behind the oval spray opening (7).

When the pressure is removed from the actuator button (6), the spring associated with the valve stem (VS) of the container (1) forces the sprinkler channel (15) upwards, just after which the leaf spring (45) ) dependent on the finger pad (38) forces the actuator button (6) back to its original position.
