Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dispensing device cap adapted to cooperate with a pressurized container in the form of an aerosol can.

Known dispensing device caps used in the past are generally made of two parts, one fixed part and one movable part. The fixed part formed by the cap body is fixed to the top part of the cooperating pressurized container, while the movable part in the form of a push button is adapted to be attached to the outlet guard piece of the pressurized container provided with the valve. The valve is often located in a cup-shaped body secured by an annular crimp rim in the head portion of the container body. The cap body is attached to the crimp rim of the valve support cup of the pressurized vessel.

In this case, the cap body has a smaller diameter than the container body.
The pushbuttons received within the cap body necessarily have small dimensions and are therefore difficult to operate. Attachment of the cap body may take place directly on the side wall of the container body, for example by engaging with a gripping action a continuous or discontinuous retaining ring on the bottom of the cap body in a preformed groove in the side wall of the container. is even more advantageous. In this case the cap body has a diameter approximately equal to the diameter of the container. The push button received within this container has a larger diameter and is therefore easier to operate. In the conventional system, the pushbutton is provided with a right-angled bending duct.

The axial branch of this duct cooperates with the outflow guard of the valve, and the radial branch of this duct terminates in a discharge nozzle. The discharge nozzle is located opposite a window cut into the wall of the cap body. Advantageously, the bending duct of the push button carries a radially extending tongue, and the length of this bending duct is approximately equal to the inner diameter of the cap body to facilitate manipulation. In the known design, the pushbutton is arranged between two guides that are integral with the cap body.

These guides are used to guide the movement of the push button perpendicular to the gutter axis of the push button into the cap body along the marking line of the sliding piece of the outflow pipe section of the valve. In order to reduce as much as possible the force required to lower the guard piece of the outflow valve by means of the push button and to reduce the risk of damage to the valve during operation, the pivoting face line of the push button should be placed as close as possible to the wall of the cap body. and that said axis be located approximately at the height of the top end of the outflow guard piece of the valve. To accommodate this condition, the tongue of the push button is placed not too far below the top surface of the cap body, which has a normal height, so that the top of the cap is placed at a height that is considerably lower than the top of the cap body. An unsightly break occurs due to the pushbutton tongue located between the two guides. The front face of the push button in which the discharge nozzle is located is provided with an extension extending toward the bottom parallel to the marquee line of the cap body and attaching the pivot piece of the push button to the cap body at the bottom. The height of said extension is selected such that the pivot axis is located approximately at the level of the outlet section of the valve and the pushbutton tongue is located approximately at the level of the top surface of the cap body. Such known devices are described in FR 1,512,794, US 3,180,531 and FR 2,401,703. French Patent No. 1512794
The specification shows a device in which the front extension of the push button is associated at its lower end with a gripping action in a hole partitioned by the extension of the cap body.

U.S. Pat. No. 3,180,531 shows a device in which the extension or pin of the push button cooperates with the lower horizontal wall of a recess formed in the cap body.

FR 2,401,703 shows a device with a push button having an extension or bar that cooperates with a stop piece of the cap body.

An object of the present invention is to pivot the pushbutton so that the downward movement of the dispensing device cap rests against the edge of the valve support cup when the dispensing device cap is positioned on the cooperating container. The object of the present invention is to provide a device in which each guide is partitioned by a housing that acts to limit the amount of movement. Therefore, the present invention consists of two parts, one fixed and the other movable, the fixed part being
The cap body is fixed to the side wall of the aerosol can-shaped pressurized container by a gripping connection, and the movable part is moved between two guides that are integral with the cap body and connected to the upper surface of the cap body. Consists of a push button rotatably mounted inside the cap.
A dispensing device cap adapted to cooperate with a pressurized container in the form of an aerosol can, the push button having a bag wire cooperating with an outlet piece of a valve provided on the pressurized container with which it cooperates. a flexural duct having a directional branch portion and a radial branch portion that exits opposite a discharge nozzle carried by a front surface of the push button; is provided with an operating tongue extending substantially in a plane perpendicular to the longitudinal branch of the bending duct in a region opposite to the flexure duct, the length of the push button measured perpendicular to the axis of the cap body; Sao,
a front surface of the push button, which is approximately equal to the inner diameter of the cap body and in which the discharge nozzle is disposed, is provided with an extension extending toward the pressurized container parallel to the axial branch of the bending duct; An articulation piece is provided near the bottom of the valve for articulating the push button with the cap body, the articulation axis of the articulation piece being located approximately at the level of the end of the outlet piece of the valve. In the dispensing device cap, the operating tongue is disposed at a level substantially above the top surface of the cap body, and the cap body 10,
10a and the push buttons 30, 71 by two coaxial pin pieces 39 provided at the bottom of the front extensions 38, 75b of the push buttons and integral with the extensions. , 76, each of these pin pieces 39
, 76 to the two guides 1 of the cap body 10, 10a.
6, 68 at the bottom of the window 1 of the cap body with the ejection/slip of the push button 30, 71 arranged oppositely;
Pin housing 23, 70 placed near 3, 13a
The above two guides 1 are connected with each other with a gripping action inside.
6, 68 substantially on the annular crimp rim 4, 62 of the valve support cup of said pressurized container when said dispensing device cap is associated with a gripping action to a cooperating pressurized container. The dispensing device cap is characterized in that it can be placed in a leaning state, and the pin housings 23, 70 are opened downwardly toward the pressurized container.

According to one embodiment of the push button, the front extension of the push button has a groove-shaped cross section perpendicular to the axis of the axial branch of the flexure duct.

The two pin ends mentioned above project into the two sides of this groove. According to another feature of the invention, the two guides are substantially symmetrical with respect to the crane plane of the cap body and taper towards the window of said body.

A push-button discharge nozzle is located on the opposite side of this window. Each edge of the operating tongue of the pushbutton cooperates with two guides to push substantially in a plane orthogonal to the two coaxial pin ends passing through the alignment line of the outlet section of the valve. It's better to move the button.

Furthermore, the operating tongue is preferably arranged at a height close to the hammer line of the radial branch of the bending duct.

According to a first embodiment of the dispensing device cap according to the invention, the operating tongue of the push button is integral with two restraining flaps in the region opposite the pivot axis. Each restraining flap can rest on the bottom of a recess projecting outwardly from the pushbutton tongue and disposed in each guide of the cap body. The two constraining flaps described above serve to limit the pivoting movement of the pushbutton in a direction opposite to that corresponding to the lowering of the outlet section of the valve. Furthermore, when the cap body is inverted during assembly, the pushbutton is pressed until the two coaxial pin pieces engage with a gripping action within the housing, and the two restraining flap pieces rest against the bottoms of the two guide recesses. It descends between two guides until . In this way, the pushbutton cannot be separated from the cap body with the protective plate during this operation. According to a second embodiment of the cap according to the invention, it is desirable to temporarily hold the push button in a fixed position within the cap body, in particular to facilitate the assembly of the cap onto the pressurized container. That is, at least one of the restraining flaps of the pushbutton is provided with a recess cut out in the two guides so as to temporarily prevent the pushbutton from pivoting about its pivot axis within the cap body. On the other side of this recess there is provided a piece which can be associated with a gripping action when substantially abutting the bottom. This piece may, for example, be a complementary shaped cutout cut into the recess or, on the contrary, a retaining ring associated in the recess into which a protruding retaining ring provided in the recess is gripped. Advantageously, the sides of the recesses with which the restraining flaps are associated with a gripping action are beveled. The axes of the side portion and the cap body diverge toward the top of the cap body. When the restraining sag leaves its gripping association position in this way, the two restraining sag pieces are free to move within the recess and are unable to return to their gripping association position on their own. . In the dispensing device cap according to the first embodiment described above, the push button is moved by the outlet part of the valve to the position where the operating tongue is closest to the top of the cap, when the cap is not yet assembled on the container. The push button is freely movable with respect to the cap body and occupies a position not exactly opposite the valve when the lower end of the axial branch of the duct is capable of automatic positioning of the present cap on the cooperating container.

According to the second embodiment described above, the positioning of the axial branch of the duct with respect to the valve is mechanically controlled by providing a retaining piece for keeping the push button in a position closest to the top of the cap during assembly of the operating tongue. to avoid problems during automatic positioning. However, the first actuation of the container causes the retaining piece to disassociate, thereby making it impossible for the push button to subsequently return to its initial horizontal position.
The operating tongue therefore remains slightly tilted during use of the container, which is not the best solution. This problem can be solved by a third embodiment in which the elastic strip ensures that the push button is held in a substantially horizontal operating position with the actuation tongue closest to the top of the cap.

More precisely, the dispensing device cap according to this third embodiment projects forwardly from said front face beyond the pivot piece on the side opposite the radial branch of the duct in the extension of the front face of the push button. Equipped with elastic strips. In this manner, when the pushbutton is positioned within the cap, this strip resiliently contacts the inner wall of the cap and pushes the pushbutton toward a substantially horizontal position where the operating tongue is closest to the top surface of the cap. return. The strip is preferably molded integrally with the push button.

Advantageously, this strip has a thickness approximately equal to the thickness of the front surface, but a width less than the width of this front surface, such that the strip is elastically deformable in front of said front surface. The elasticity of the strip is such that this elasticity is sufficient to restrain the push button in a position where the operating tongue is closest to the top surface of the cap without relying on the return piece cooperating with the outlet piece of the valve. good.

According to another feature of the invention, a hole is cut out in the top of the cap body between the two guides in an area opposite the discharge nozzle of these guides, in order to be able to operate the push button.

This hole is closed by a protective plate connected to the top by a molded release stop before the first use of the unit formed by the present dispensing device cap and associated pressurized container. Unless this protective plate is pulled away from the cap connected to the container, the user will not be able to touch the acquired unit or at least not be able to remove the dispensing agent that the manufacturer has placed in the pressurized container. Make sure to lock everything up. Also, by breaking or tearing the protective plate, at least one push button that cooperates with the valve can be removed.
This means that the container can be used in advance. The protective plate is provided with a pre-cut deformable flap located centrally on the top of the cap body which can be manipulated at the factory to test the proper functioning of the unit with a push button housed within the cap body. Good.

The valves of the cooperating pressurized vessels may or may not be provided with protrusions as usual.

According to another feature of the invention, the side wall of the cap body includes a continuous or discontinuous retaining ring therein adapted to fit within a peripheral groove formed in the body of the pressurized container.

The body of the cooperating pressurized container is made from a single piece by extruding a metal beret, such as aluminum, and subsequently forming the top portion of the container body into a frustum shape. The valve support cup is then crimped to the top portion of the container body.
In a one-piece container of this kind, detailed in French patent no. It is a groove formed in advance. In the case of so-called two- or three-piece pressurized containers in which the cylindrical side wall of the container body is connected by an annular crimp rim to the crimped crown of its valve mounting cup, the peripheral attachment point 1 of the barrel cap is as described above. It is located on the underside of the circular crimp rim. It is also an object of the present invention to provide a dispensing device formed firstly by a pressurized container in the form of an aerosol can and secondly by a dispensing device cap adapted to be attached to one end of said pressurized container, and which is attached to a side wall of said pressurized container. A unit using a cap as described above as a dispensing device cap is provided with a retainer which serves to secure the cap body by means of a gripping connection.

Embodiments of the dispensing device cap of the present invention will now be described in detail with reference to the accompanying drawings. As shown in the figure, the aerosol can-shaped pressurized container 11 is obtained by extrusion molding, for example, an aluminum pellet.

The container 1 consists of a bottom (not shown), a cylindrical side wall 2 and a frustum-shaped top 3. The valve support cup is secured to the end of the frustum-shaped top 3 by an annular crimp rim 4. The outlet part of the valve provided on the container 1 is constructed in the usual manner by a tube part 5 which can be moved along the marking line.

A peripheral retaining groove 6 is formed in the connecting area between the side wall 2 and the cup-shaped top 3 of the container 1. The top part of the pressurized container 1 is adapted to be fitted with a dispensing device constructed in two parts of molded plastic material.

These two parts are the cap body 10 and the push button 30 which is pivotally connected to the cap body. The cylindrical side wall 11 of the cap 10 has a discontinuous retaining ring 1 inside its lower portion.
2 is formed.

The retaining ring 12 allows the cap to be secured substantially irreversibly to the top part of the container 1 by means of a gripping engagement within the retaining flange 16. A notch 14 diametrically opposed to the window 13 is cut out in the top portion of the side wall 11 in the region of connection with the top 15 of the cap body 10. Each side line part of the window 13 and the notch 14 is connected to the cap body 1.
They are interconnected in pairs by two guides 16, 16 extending into the 0. The two guides 16 , 16 are arranged symmetrically on each side of the axis of the cap body 10 and also substantially taper toward the window 13 . Each guide 16 is joined to the top 15 of the cap body 10. In the guide area opposite the window 13, the two guides 16, 16 form a recess 17. When attaching the dispensing device cap to the pressurized container 1 by gripping action, the two guides 1 of the cap body 10
6 and 16 correspond to the crimp rim 4 of the valve support cup.

For this purpose, two semicircular recesses 18, 18 are formed in each one of the two guides 16, 16, with which the crimp rim 4 is associated. As shown in FIG. 3, a hole 19 is cut into the top 15 of the cap body 10.

The mutually opposing edges of the hole 19 are separated by respective guides 16. The hole 19 extends around the top 15 of the cap body 10. The hole 19 is closed by a protective plate 201 connected to the top 15 of the cap body 10 by a molded pull-off piece 21. As shown in FIG. 3, a pre-cut hanging piece 22 is provided on a portion of the protective plate 20 located at the center of the top portion 15. As shown in FIG.

In the factory, by pressing the pre-cut flap 22 with a tool, the push button 30 can be pressed to control the atomization of the dispensing agent placed in the container 1 without separating or damaging the protective plate 20. A push button 30 is arranged in the cap body 10 between the two guides 16,16.

The push button 301 is also equipped with a right angle duct. The outflow guard piece 5 of the valve is fitted into the axial branch portion 31 of this duct. The radial branch portion 32 has its nozzle (
It closes at the end 33 opposite the discharge orifice (not shown). The discharge nozzle is located on the front surface 3 of the push button 30.
It is installed on 4. This discharge nozzle is the cap body 10
It is arranged opposite to the window 13 of. The radial branch portion 32 of the duct is provided on its upper side with an operating tongue 35 extending in a plane approximately parallel to the line of the branch portion 32.

The operating tongue 35 narrows towards the window 13 of the cap body and cooperates with the two guides 16, 16 to push the push button 3.
It is provided with two side edges which ensure that the valve 0 is guided approximately in a plane passing through the sliding axis of the outflow guard piece 5 of the valve. The length of the operating tongue 35, measured perpendicular to the axis of the cap body 10, is approximately equal to the internal diameter of this cap body.
The part of the operating tongue 35 opposite the radial branch 32 of the duct is formed with a recess for receiving the user's finger acting on the push button. There is a notch 1 in the tongue 35.
A substantially right-angled curved portion 37 is provided on the 4 side. The front face 34 of the push button 30 is provided with an extension 38 extending downwardly parallel to the axial branch 31 of the duct.

Front extension part 38 perpendicular to the enemy line of the axial branch part 31
The cross section is miso-shaped. Near the lower end of the front extension 38, on each side of the groove formed by the extension 38 are embossed two coaxial pin pieces 39, 39 obtained by molding together with the push button 30. One piece is formed. Two coaxial pin pieces 39, 39 extend perpendicular to the flyline of the flyline branch 31 of the duct.

Each pin piece 39 is clamped into two housings 23, 23 which open toward the bottom. Each housing 2
3 is composed of a cylindrical cavity facing downward and fitting into a trapezoidal hole. The two walls of the hole taper toward the cavity. On the opposite side of the front extension 38, the two side edges of the operating tongue 35 are bent and extend downward from the hanging tab 40'.

The push button 3 of the two bent hanging pieces 40, 40 is connected to the side that is not connected to the branch part 31 in the direction of the duct's parallax.
The push button 30 is arranged in a plane perpendicular to the axis of the push button 30 and protrudes outward from the push button 30.

Said side has two guides 16 when the tongue 35 of the push button 30 is approximately parallel to the top 15 of the cap body 10;
It almost touches the bottom part 17a of each depression 17 cut out in 16. Two restraining hanging pieces 40, 40 and each recess 17
has the purpose of limiting the upward pivoting movement of the push button 30 in a position where the operating tongue 35 is practically at the level of the top 15 of the cap body 10.

To install the push button 30 within the cap body 10,
Stand the cap body 10 with the top facing down, and press the push button 30.
between the two guides 16, 16, the two pin pieces 39, 3
9 until it engages with a gripping action in its housing 23. In this position the two restraining flaps 40 substantially rest against the bottoms 17a of the recesses 17 of the two guides 16,16. That is, two restraint hanging pieces 40, 40
The presence of the pushbutton 30 within the cap allows the pushbutton 30 to be lowered without risk of damaging the protective plate 20. The dispensing device cap is attached to the pressurized container 1 described above using a discontinuous retaining ring 1 provided at the bottom of the cap body 10.
2 in a preformed groove 6 of the pressurized container 1 with a gripping action.

The fixing of the present cap to the pressurized container 1 can be done without special precautions and without the risk of pressing down on the outlet pipe part 5 of the valve. The reason is that this downward movement is limited by the impact of the two guides 16, 16 on the crimp rim 4 of the valve support cup. Even if the protective plate 20 is removed,
Since the tongue 35 of the push button 30 is located approximately at the level of the top 15 of the cap body 10, no unsightly break appears between the two guides 16, 16 of the cap body 10.

Furthermore, since the pivot axis separated by the two pin pieces 39, 39 is approximately at the same height as the end of the valve outflow guard piece 5, the length of the tongue piece 35 of the push button 30 is also the same as that of the cap. Since it is approximately equal to the inner diameter of the body 10, it goes without saying that the operation of pressing the push button 35 and therefore the outflow guard piece 5 of the valve becomes particularly easy. Also, due to the presence of the front extension 38, the dispensing device cap of the present invention has the advantage that the presence of a break between the two guides 16, 16 of the cap body 10 does not have any adverse effect on the operation of the pushbutton 30 or on its aesthetic appearance. Can be made to any height. A dispensing device cap having the same diameter as the height of the seed can be easily obtained by simply adjusting the height of the front extension 38 of the duct lateral branch 31 and the two restraining flaps 40, 40. It will be done. The dispensing device cap of the present invention according to the embodiment shown in FIG.
Compared to the illustrated embodiment, this is similar with the difference that the push button is held in a fixed position by a gripping association with the cap body 10.

The cap body 10 of FIG. 5 differs from those of FIGS. 1 to 4 substantially only in the shape of the recesses 27 arranged in the two guides 16, 16 of the cap body 10. Each recess 27 has a bottom 27a connected to a wall 27b that extends perpendicular to the rut line of the cap body 10 and is slightly inclined relative to the axis of the cap body 10. The neck diagonal wall 27b and the marquee line of the cap body 10 substantially widen toward the top 20' of the cap body 10. A notch 28 is cut out in the oblique wall 27b near the area where it connects with the recess bottom 27a. Compared to the push button 301 of FIGS. 1 and 2, the push button 301 of the embodiment shown in FIG. The substantial difference is that an unbent constraining sag 50 is provided. The two restraining tabs 50, 50 also function to limit upward pivoting movement of the push button 30.

Each flap piece 5 is provided with a raised retaining bead 51 on its edge facing towards its pivot axis. The retaining bead 51 can be associated with a gripping action in the cutout 28 of the recess 27 to prevent rotation of the push button 30 within the cap body 10. To fix the push button 30 inside the cap body 10, turn the cap body 10 upside down and insert the push button 30 between the two guides 16, 16 using two pin pieces 39.
, 39 into its housing and by lowering the retaining beads 51 of the restraining flaps 50 into the notches 28 of the recesses 27, respectively, until they engage with a gripping action.

In this position, the pushbutton 3 is prevented from rotating within the cap body 10, facilitating the installation of this unit into the pressurized container 1. To pull the guard plate 20 apart, the user presses the push button 30 to remove it from its gripping associated position.

Pushbutton 3 rotates around the pivot axis of the river. In this case, the inclination given to the sides 27b of the recess 27 allows the constraint hanging piece 50 to move freely within the recess 27. The restraining sag 5 cannot return to its original gripping position unless the push button 30 is pulled upward. In FIG. T, the top of the pressurized container 60 is shown in chain lines.

The container 6 terminates in a truncated portion 61 with an edge 62 crimped to a cup-shaped body supporting a valve 63. The dispensing device cap of the present invention includes a body 10a to which a container 6 is fixed. The body 10a has a side wall 64 with an inner retaining ring 65 in its bottom portion adapted to engage in a gripping manner a groove 66 formed in the top portion of the container 60. The present cap is thus attached with its base to the top portion of the container 60. The body 10a of the cap further comprises a top 67 and two inner walls or guides 68, 68 which are integral with the top 67 and the side walls 64 and separate the housing for the push button 71 of the cap.

The inner edge of each guide 68 is formed with a notch 69 adapted to contact the crimp rim of the crimp edge 62 of the container 60 so that when the retaining ring 65 is engaged with a gripping action within the groove 66, each guide 68 also hits the container 60. Furthermore, each guide 68 separates two housings 70 in which a pushbutton 71 can be pivotally mounted.
To be more precise, the push button 71 is located at the front part of the push button on the opposite side of the fuselage Ioa from the window 13a.
The main body 72 is formed into a duct which is closed at 5a and has a branch part in the distal direction at a main body extension part 74 in the parallax direction.

The wire direction extension portion 74 is adapted to cooperate with the outflow guard piece of the valve 63. The body 72 of the push button 71 has a front face 75 in its front portion. The front side 75 is an extension part 75
b toward the container 60. Extension portion 75b
two pins 76 on the bottom and sides thereof, adapted to be resiliently retained within the housing 70 of each cap guide 68;
76 are provided. Each pin 76 allows the pushbutton 71 to be pivoted relative to the cap about a line approximately perpendicular to the plane of FIG. According to the embodiment of FIG. 7, the extension 75b of the front face 75 of the pushbutton 71 is fitted with a strip 77 which extends across the container 6 (i.e. toward the bottom in FIGS. 7 and 8).

The strip 77 is fully curved toward the front so that when the push button 71 occupies the position closest to the top 67 as shown in FIG. It is curved enough toward the front to permanently apply a force strong enough to always restore it. To secure the dispensing device cap shown in FIG.
By pressing the push button 71 toward the cap body 1
Introduced into 0a.

Strip 77 directs pushbutton 71 toward the right in FIG. 7 and back. Each pin 76 corresponds to each guide 68 of the cap.
Once in contact with the housing 70, each pin 76
is guided through the enlarged entrance hole and the strip 77 is inserted into the fuselage 10.
progressively press against the side wall 64 of a. Installation of the present dispenser cap is complete when each pin 76 is associated with the housing 7. The body 72 of the push button 71 is preferably provided with bent flaps 78 on each side thereof. Hanging piece 7
8, when these hit the bottom of the guide 68, the push button 7
The upward movement of 1 is restricted. Each guide 6
8 is provided with a recess 27c having a bottom 27d at this position. A push button strip formed by integral molding with a push button has been described. However, this strip can also be attached or have a different shape. In the configuration shown in FIG. 8, the width of the strip 77 is narrower than the width of the extension 75b so that the strip 77 deforms first. This initial deformation is also achieved by a strip having approximately the same width as the extension 75b, but with a thinner thickness. Whatever the shape of the return strip, it is desirable to apply sufficient return force to ensure that the push button always returns to the top layer without the need to apply force to the push button by the valve.

When the main cap is attached to the container 60 in this way but is not fixed, the axially extending portion 7 of the push button 71
4 is positioned along the cap axis. In this way, the cap can be automatically positioned on its container since the extension 74 is properly positioned opposite the outlet piece of the valve 63. Although the present invention has been described in detail with reference to its embodiments, it is obvious that the present invention can be modified in various ways without departing from its spirit.
