Disclosure of invention

An object of the present invention is to provide a drive for an aerosol dispensing device having good ergonomics and high operational reliability. A key sign of operational reliability is the elimination of lateral pressure on the control valve, namely on the valve stem of the aerosol container in which the actuator is used.

An additional objective of the present invention is to provide a drive for an aerosol dispensing device having good resistance to premature release, i.e. good resistance to the release of the contents of the dispenser to the desired moment, for example during production or transportation.

The indicated resistance to premature release is achieved through the use of a drive button, which requires considerable effort to move it to the operating position. Naturally, this first movement is independent of the movement that causes the release of the contents of the aerosol dispenser.

According to a first aspect of the invention, there is provided an actuator for an aerosol container held in a hand having a dispensing valve and configured to be mounted in the upper part of the aerosol container, said drive comprising (ί) a cup-shaped cap connected to the container and having a side wall having a spray hole through which aerosol can escape, and the upper wall having a cutout through which the spray channel passes, while the boundaries of this cutout limit lateral movement flax channel;

(ίί) a spray channel fluidly coupled to the valve and configured to spray through the spray hole in the side wall of the patch cap;

(w) a drive button having a pad under the user's finger and a push element extending downward from the pad; moreover, the button is installed in the cap with the possibility of actuating the actuator by first moving in a direction approximately transverse to the vertical axis of the cap, and second moving by pushing the button into the cap, while the pressure element is configured to press the spray channel, and the spray channel is configured to pressing the valve after the first movement of the button, in which the drive button is configured to translate the first movement to a position in which dependent second move causes release of related content

- 1 023568 with a capacity drive, the pressure element is configured to hold it from pressing the spray channel before the first movement of the button by means of a protrusion extending downward from the drive button pad and interacting with the protrusion that extends upward from the upper surface of the upper wall, said protrusion passing down from the platform, made with the possibility of sliding downward for the protrusion that extends upward from the upper surface of the upper wall, after the first movement of the drive button, with this drive button is made with the possibility of making the first movement when applying a force of at least 5N.

According to a second aspect of the present invention, there is provided a method for applying a cosmetic aerosol composition to a human body, comprising using a drive according to the first and second aspects of the invention.

Detailed description

In this description, the terms of the direction of the top, vertical and horizontal should be understood as referring to the drive in its operating position when it is mounted on top of a vertical aerosol container, as shown in FIG. one.

The term “go down” should be understood as referring to elements protruding downward in relation to other elements.

The term lateral should be understood as referring to a plane substantially perpendicular to the vertical axis of the actuator when positioned as described in the two paragraphs above.

The vertical axis of the drive can be understood as its main axis, and the term horizontal refers to a plane perpendicular to this axis.

The front should be understood as referring to the horizontal plane and facing the spray hole, and the rear as facing away from it.

Aerosol actuators, actuated by a drive button having a lateral displacement element, are prone to applying lateral pressure, either directly or indirectly, to the valve, in particular to the valve stem, of the aerosol container to which they are attached. While this is fully suitable for tilt valves, valves operating with upward pressure may be damaged by such lateral pressure, which should be avoided. The present invention is most preferably used with valves operating by applying pressure from top to bottom.

In addition, it is desirable that the aerosol actuators are not able to cause premature release of the contents of the dispenser.

The present invention is directed to solving the aforementioned problems by creating a drive, the drive button of which is adapted to be translated during the first movement in a position in which the second movement causes the contents to be connected to the drive. By keeping these movements independent, the lateral force on the valve stem is minimized and means are provided to prevent premature release.

In preferred embodiments, the first movement of the drive button does not have a return mechanism; that is, when the drive button is moved to the operating position by the first movement, it remains in that position. This feature has the advantage that there is no need to move the button forward to the operating position during subsequent use of the dispenser.

Prevention of premature release is additionally provided by setting a suitable minimum force for the first movement of the drive button, which moves it from the idle position to the working position. This force is at least 5 N, preferably at least 10 N and more preferably at least 15 N. The larger of these efforts are particularly suitable for preventing accidental release during assembly of the dispenser.

The lateral force exerted on the valve stem is further minimized by placing it in the cutout or hole in the fixed base, and the cutout or hole is usually made with the possibility of tight or tight fit. The fixed base is the top wall of the actuator cap.

It is especially important that the lateral movement of the spray channel is limited in the direction in which the drive button, which usually represents the direction to the spray hole, is operated.

The width of the spray channel in the front to back direction at the point where it passes through the cutout is usually such that the channel fills at least 90%, more often at least 95% and most preferably at least 98% of the width of the cut in the front to back direction point.

The cutout in the upper wall is preferably an opening that completely surrounds the spray channel. Preferably, the hole has a circular cross section. When the cutout in the upper wall is a hole with a circular cross section, the cross-sectional area of the spray channel at the point where it passes through the hole is usually such that the spray channel fills at least 95%, more often 97% and most preferably at least 99% the cross-sectional area of the hole at the specified point.

- 2 023568

The point where the spray channel passes through a cutout or hole should be understood as referring to the drive in its rest state, and preferably also to the drive when the spray channel is in a state in which it is fully depressed.

In some embodiments, the rotational movement of the spray channel is also limited. In such embodiments, additional operational reliability is usually provided.

In preferred embodiments of the present invention, the drive button is connected to the top wall of the cap. In this position, the drive has particularly good ergonomics, i.e. It is easy to use.

When the drive button is connected to the top wall of the cap, the movement of the drive button from the first position to the second preferably occurs in the direction of the spray hole.

The invention is particularly suitable for use with actuators having an angular actuator button, in particular when located on an inclined section of the upper wall of the cap supporting the actuator button. The inclined portion of the top wall of the cap preferably extends upward at an angle of 10-50 ° to the horizontal, more preferably, at an angle of 25-40 ° to the horizontal.

The pressure member typically extends downward from the pad under the finger in the central region. It preferably has a lower surface of a wedge-shaped profile, tapering from rear to front, i.e. made wider at the back.

In preferred embodiments, when the button is in the idle position, a pressure member that extends downward from the pad under the finger of the actuator button and interacts with a protrusion that rises from the upper surface of the upper wall prevents the pressure member from being pressed onto the spray channel. Preferably, two sets of protrusions are provided.

In more preferred embodiments, the downwardly extending protrusion or protrusions mentioned in the previous paragraph may / may slide downward behind the protrusion or protrusions that rise from the upper surface of the upper wall when the actuator button is in the operating position.

In preferred embodiments, the cap is configured to lock in place on top of the aerosol container. This fixation can be obtained by finning around the lower inner edge of the cap and the associated trough in the direction of the upper part of the aerosol container. By locking the cap in place at the top of the aerosol can, reliability is improved.

The spray channel used in accordance with the present invention is fluidly coupled to a valve of the container with which the actuator is used. It usually has two parts fluidly connected to each other and to the valve. Typically, the spray channel has a vertical portion configured to be located on top of the valve stem on top of the aerosol container with which the actuator is used. During operation, the pressure member typically exerts pressure on the top of the vertical portion.

The spray channel typically comprises a vertical part and a part angled to said vertical part, the two parts being fluidly coupled. The angle between the parts is usually from 100 to 130 °, preferably from 110 to 120 °. The features indicated in this paragraph work in combination with the top wall of the cap having an inclined section (see above) to facilitate ergonomic use of the drive.

The drive is usually made of plastic, most often a method involving injection molding. The spray channel and cap can be made of polypropylene. Most of the drive buttons can be made of acetal copolymer; however, the upper surface of the drive button is preferably made of thermoplastic elastomer to provide improved grip.

The aerosol container for use with the drive preferably contains a cosmetic composition for application to the surface of the human body. With such use with such compositions, the ergonomic and reliability advantages of the present invention are particularly advantageous.

The tank for use with the drive is usually made of tinplate or aluminum.

The drive (1) is formed of three components: a cup-shaped cap (3), a spray channel (4) and a drive button (5).

The cap (3) and its features are shown in FIG. 4-12. The cap (3) has a circular cross section formed by the side wall (6), the diameter of the cap (3) decreases towards the upper end. The side wall (6) has an oval spray hole (7), which should be located in front of the drive (1). The oval spray hole (7) has a short axis located in the horizontal direction and directed towards the upper end of the side wall (6).

Two support wings (8) protrude inward from the side wall (6) on both sides of the spray hole (7). These supporting wings (8) are thin walls extending from the upper part of the side wall (6) to a point about half its length. From the side of each support wing (8) facing the spray hole (7), a guide wall (9) of the spray channel protrudes. These guide walls (9) of the spray channel of both wings (8) are located in a vertical plane that is perpendicular to the axis directed from front to back (AA) of the drive (1). They extend from the support wing (8) towards each other in the vicinity of the spray hole (7). The guide walls (9) of the spray channel end with the formation of a notch between them, which is always slightly larger than the short axis of the oval spray hole (7).

At the bottom of the side wall (6) there is a ribbing (10 and 11) for locking by locking the cap (3) on top of the aerosol container. The ribbing consists of six smooth beads (10), evenly distributed along the lower inner surface of the side wall (6) and alternating with a corrugated bead (11). Detailed cross-sectional views of the shoulders (10 and 11) are shown in FIG. 8 and 9, respectively. The fins snap into place in a recess (12) around the upper part of the aerosol container (1) (see Fig. 3).

The cap (3) also has an upper wall (13) forming a hole (14), which is designed to accommodate part of the spray channel (4) (see below). The upper wall (13) is connected to the side wall (6) by means of an internal wall (15), which varies in height from the front to the rear side, while it is relatively high in front and decreases in the backward direction.

The upper wall (13) has a larger segment (16), inclined upward to the front of the drive at an angle of approximately 32 ° to the horizontal, and a smaller segment (17) located approximately horizontally (see Fig. 11). A smaller segment (17) is located at the front end of the upper wall (13). The hole (14) in the upper wall (13) is located in the center, where the larger (16) and smaller (17) segments are connected, but mainly formed by the latter.

On each side of the hole (14) in the direction perpendicular to the direction of movement of the drive button (5), two protrusions (18) are made extending upward from a smaller segment (17) of the upper wall (13). Each of the protrusions (18) on the side adjacent to the hole (14) has a ridge (19).

A substantially circular wall (20A and 20B) with an opening defines a hole (14) and extends up and down from the upper wall (13) in the vertical direction (see FIG. 12). The lower portion (20A) extending downward from the upper wall (13) is longer than the upper portion (20B) extending upward from the upper wall (13). The lower portion (20A) extending downward from the upper wall (13) has a cutout (21) on its front portion parallel to the additional walls (22) extending from the edges of the cutout (21) to the spray hole (7). These parallel additional walls (22) have lower edges (23), obliquely ascending in the direction of the spray hole (7). Parallel additional walls (22) end at the level of the outer edge (24) of the inner wall (15).

In the upper section (20B) of the wall with an opening that extends upward from the upper wall (13), said projections (18) abut, which also extend upward from the upper wall (13). From the front side of the upper portion (20B), a raised arch (25) extends connecting the upper portion (20B) with the inner wall (15) and connecting the cutout in the smaller segment (17) of the upper wall (13) and the upper portion (20B) of the wall with an opening . The raised arch (25) has a dome shape at the top, and its inner surfaces (26) are in contact with the inner surfaces of parallel additional walls (22), extending from the edges of the cutout (21) in the lower section (20A) of the wall with an opening extending downward from the upper wall (thirteen). The raised arch (25) is made to accommodate a portion of the spray channel (4) (see below).

- 4 023568

The inner surface (20C) of the substantially circular wall (20A and 20B) with the hole is continuous and has vertical recesses (20Ό) on each side aligned with two protrusions (18) that extend upward from the upper wall (13) on each side of the hole (14).

From a larger segment (16) of the upper wall (13), a central protrusion (27) extends upward, having a rear surface (28) passing through an opening (29) in the upper wall (13). This extensive rear surface (28) forms an essentially supporting wall and will be referred to as essentially such.

Hinge bodies (30) are attached to the back side of the larger segment (16) of the upper wall (13). They are intended to limit the hinge sections of the drive button (5) (see below). The housings (30) are located around parallel slots (31) in the upper wall (13), which extend back under the hinge bodies (30), i.e. in the direction opposite to the direction in which the drive button (5) is pressed. The housings (30) are hereinafter described in more detail with reference to FIG. sixteen.

Hinge bodies (30) are attached to the back side of the larger segment (16) of the upper wall (13). They are intended to limit the hinge sections of the drive button (5) (see below). The housings (30) are located around parallel slots (31) in the upper wall (13), which extend back under the hinge bodies (30), i.e. in the direction opposite to the direction of pressing the drive button (5). The housings (30) are hereinafter described in more detail with reference to FIG. sixteen.

Two additional parallel slots (32) are located on a larger segment (16) of the upper wall (13). These additional parallel slots (32) also extend from front to back and are located on each side of the central protrusion (27), passing directly behind the protrusions (18), which extend upward from the upper wall (13) to a point at a level with the rear surface (28) of the central protrusions (27).

The spray channel (4) is shown in FIG. 13. It contains a vertical part (33) and a part (34) located at an angle of about 114 ° to the vertical part (33), i.e. at an angle of 24 ° to the horizontal. The vertical part (33) and the inclined part (34) are in fluid communication.

The vertical part (33) of the spray channel (4) is adapted to be mounted on the valve stem of an aerosol container (1) (see Fig. 3) and expanded in the base (36U) to facilitate this installation. The vertical part (33) of the spray channel (4) is also made with the possibility of tight fitting in the hole (14) in the upper wall (13) of the cap (3) (see below). Thus, lateral movement of the spray channel (4) is limited. The vertical part (33) of the spray channel (4) has an elastic region (35) on top, which is pressed by the part of the drive button (5) under the action of the drive.

The vertical part (33) of the spray channel (4) has a vertically oriented elongated block (33A) protruding from either side, i.e. in the direction perpendicular to the direction of the drive button (5). These oblong blocks (33A) are slidable in vertical recesses (20Ό) in the inner surface (20C) of a substantially circular wall (20A and 20B) with an opening. Thus, the rotational movement of the spray channel (4) is limited.

The vertical part (33) of the spray channel (4) has two small limiting clamps (33B), each of which is slightly higher than the oblong blocks (33A) on either side of it. These clamps (33B) are used to hold the spray channel (4) in place during production and release during the first use of the actuator (1).

The inclined part (34) of the spray channel (4) is narrower than the vertical part (33), both inside and outside. The inclined part (34) extends from the top of the vertical part (33) to the spray hole (7). At the end with the spray hole of the inclined part (34) there is an oval disk (36Ό), made with the possibility of installation directly behind the oval spray hole (7) and making the cutout invisible from the outside at any time. Also at the end of the inclined part (34) is a traditional vortex chamber (37), made to improve the quality of spraying.

The drive button (5) is shown in FIG. 14. It consists of a pad (38) under the finger and various parts extending downward from it. The pad (38) under the finger is longer in the forward-backward direction, i.e. in the direction in which it is made with the possibility of sliding. The pad under the finger is mounted on the upper wall (13) of the cap (3). The pad (38) under the finger is bent upward at the front end (39) to increase ergonomics of use. On its upper surface there are also curved protrusions (38A) for the same purpose (see Figs. 1 and 3 for these signs).

Two orienting clamps (40) vertically extending downward from the pad (38) under the finger are configured to pass through two additional parallel slots (32) located in the larger segment (16) of the upper wall (13), on either side of the central protrusion (27 ) The clamps (40) have two outwardly directed wedges (41) that facilitate their placement in the slots (32), while the clamps (40) are temporarily bent inward afterwards. When the drive button (5) moves forward from the first position to the second, the holding clips (40) slide forward in their respective slots (32).

- 5,023,568

From the platform (38) under the finger, along the central axis located from front to back, passes the keel-shaped pressing element (43). The specified pressure element slopes outward from the lower side of the platform (38) under the finger near its front end and ends about half the length of the platform (38) under the finger. The lower part (44) of the pressing element (43) is arranged to press the elastic region (35) from above the vertical part (33) of the actuator button (5) during operation of the actuator.

Two protrusions (46) extend under the finger from the front side of the platform (38), arranged to interact with two protrusions (18) extending upward from a smaller portion (17) of the upper wall (13) of the cap (3). When the drive button (5) is pressed forward, the lower part of the protrusions (46) extending downward from the pad (38) under the finger slides along the upper part of the protrusions (18), which raise the upper wall (13) of the cap (3), while the downward protrusions (46) do not extend beyond said raising protrusions (18). Raised ridges (19) on the protrusions (18) rising from the upper wall (13) of the cap (3) serve to guide the protrusions (46) extending down from the platform (38) under the finger during this process. When said downwardly extending projections (46) extend beyond said elevating projections (18), the drive button (5) can be pressed.

From the rear side of the platform (38), under the finger, two racks (47), bearing hinged joints (48), made with the possibility of installing hinges located in the housing (30), located in the direction of the rear of the larger segment (16) of the upper wall (13) cap (3).

Also from the back of the platform (38) under the finger passes downward pressure stand (45). It interacts with the rear surface (28) of the central protrusion (27) of the cap (3) when it slides forward. The pressing stand (45) serves to reduce the tightness of the cap (3) in the second position and, thus, eliminate any noise.

Also from the back of the platform (38) under the finger passes down the bounding clip (49) (see Fig. 15). It interacts with a limiting clip (50) (see FIGS. 6 and 16) extending upward from the top surface of the cap (3), and can help provide resistance to further movement of the cap (3). It also serves to resist any movement of the cap (3) back to its first position.

FIG. 16 shows a detailed projection of one of the hinge bodies (30). In this drawing, the front of the drive is facing right. The hinge housing (30) has two inner flanges (51) and (52), which reduce the height of the housing and provide resistance to the movement of the hinge joints (48) and the associated cap (3) from their first position to the second. They can also serve to resist any movement of the swivel joints (48) and the associated cap (3) back to their first position.

In FIG. 16 shows a bounding clip (50) extending upward from the upper surface of the cap (3) (see below).

When the drive button (5) slides forward from the first position to the second, the protrusions (46) extending downward from the front of the pad (38) under the finger extend along the protrusions (18) extending upward from the smaller segment (17) of the upper wall (13 ) cap (3). At the same time, two orientation clamps (40), extending downward from the pad under the finger, slide forward in two parallel slots located on the larger segment (16) of the upper wall (13) located on either side of the central protrusion (27), and the hinges (48) extending downward from the back of the pad (38) under the finger move in their bodies (31), as described in more detail with reference to FIG. sixteen.

When the protrusions (46) extending downward from the front of the pad (38) under the finger slide the protrusions (18) extending upward from the smaller segment (17) of the upper wall (13), the push button (5) can be pressed. At this time, the swivel joints (48) extending down from the back of the platform (38) under the finger are moved to the front part (30P) of their bodies (30) (see below). When the pad (38) under the finger is successively pressed, the pressure member (43) extending downward from it rests on the elastic region (35) on top of the vertical portion (33) of the spray channel (4). As a result, the spray channel (4) rests on the valve stem of the container (1) on which it is seated, thus opening the valve and allowing the product to be unloaded into the container (1). During the indentation of the vertical section (33) of the spray channel (4), the inclined part (34) of the spray channel (4) slides down in the arch (25), which connects the upper section (20B) of the wall (15) with the hole with the inner wall (15) and the oval disk (36) at the end of the spray channel (4) slides down directly behind the oval spray hole (7).

When the pressure from the actuator button (5) is relieved, a spring connected to the valve stem of the container (1) directs the spray channel (4) upward.
