Description

  The present invention relates to a device for product packaging and dispensing under pressure, and more particularly to a device that can be automatically emptied.

Aerosolic devices for dispensing products under pressure typically comprise a rigid container, preferably a container made of a metal or plastic material, the container comprising a product to be dispensed and a propellant for injecting the product And is housed. These devices also include a dispensing valve, usually mounted on the valve cup, and on top of the valve is located a squirter that can actuate the valve to discharge the product. The squirters are not only used to actuate the valve, but are also used to direct the product from the actuating base of the valve to the squirting orifice.
Prior to destroying or recycling such a device, it is preferable to completely empty the container, in particular to completely empty the propellant. However, it is cumbersome to hold the push button by hand until the container is empty.

For this reason, devices have already been proposed that empty the contents of the container without having to continue to apply force manually on the push button.
For some types of squirters it is relatively easy to obtain a system that empties the contents. The system first presses the push button or valve stem when the push button is moved and is secured to the valve cup that supports the container or valve so that the push button and / or valve is pushed or tilted. Hold on. This is particularly the case for squirters that are fixed directly to the valve stem, leaving the upper edge of the valve cup or container open to form the mounting area.

For example, Patent Literature 1 discloses a scatterer attached to a valve stem. A unit that empties the contents formed by the additional parts is attached to the rolled part of the valve cup to tilt the valve stem or press the squirter. Since this part is not ergonomically designed, it cannot be easily attached to a squirter or container when marketed.
Patent Document 2 also discloses a scatterer attached to a valve stem, which is protected by a cover fixed to a valve cup that supports the valve. The top wall of the cover can be tilted to press the squirters and keep the squirters pushed down to empty the contents of the container.

U.S. Pat. No. 6,089,077 discloses a squirter comprising a portion fixed on the bottom wall of the valve cup and an operating area that tilts the valve stem by moving relative to the fixed portion. Again, a protective film is secured to the valve cup that supports the valve outside the valve, and this protective film comprises a top wall that can be emptied by tilting and squeezing the working area. Product is released from the dispensing orifice formed on the working area by moderately tilting the free edge of the wall to compress the working area.
In Patent Documents 2 and 3, the protective cover also functions as a unit for emptying the contents. In normal use, every time a user wants to dispense the product, the cover is separated from the squirter, so the unit loses the cover and thus empties the container before the dispensing device is normally finished And there is a risk that this unit cannot be used to empty the container.

Also, a specific squirting device called a micro diffuser is a part that is fixed to the container and hides the inlet to the valve cap, and an operating area that moves with respect to this fixed part, and is pressed by the user. And an actuating zone where the valve can be actuated. The part of the squirter fixed to the container forms a side wall, which extends the side wall of the container and whose outer diameter is approximately equal to the outer diameter of the container, so that these also serve as protective covers for valves and valve cups. Function. The product is dispensed through a dispensing orifice formed in the side wall of the squirter. In this type of squirter, since the squirter completely surrounds the top edge of the valve cup and the container, neither the valve cup nor the top edge of the container is open, forming a mounting area Can not do it.
Patent Document 4 discloses a plurality of different types of scatterers provided with components for automatic operation. The components provided for this purpose are intended to be used in various types of squirters, in particular squirters mounted directly on the valve stem, and micro diffusers. These parts thus have a shape that can be adapted to many squirters, and thus the parts are relatively large.
British Patent No. 974278 JP2004-168356 US Pat. No. 3,137,414 International Publication No. 2006/070888

For this reason, there is a need to produce a product package and a device for dispensing under pressure consisting of a micro-diffuser-type squirter with elements capable of automatically actuating the valve.
Furthermore, there is a need to produce a device that is simple to implement and practical to use, particularly a device that has a low risk of losing elements provided to automatically actuate the valve.

Accordingly, the subject of the present invention is, according to one aspect, a device for product packaging and dispensing under pressure. The device comprises at least one container for containing a product, the top of which is equipped with a valve and a dispensing head that activates the valve to allow the product to be discharged from at least one dispensing orifice. The dispensing head includes a first part fixed to the container on the longitudinal axis of the container, and a second part that operates the valve by moving relative to the first part about the axis. Is provided. The device further comprises a unit for emptying the content, which unit can be positioned such that the valve is held in the operating position, in which the second of the dispensing head is moved. A first part for compressing the part; and a second part for contacting the first part of the dispensing head and preventing the return of the second part to which the dispensing head moves. The emptying unit is fixed on the container or dispensing head at least before the first use.
In this way, the emptying unit can be held in the emptying position, in which position the valve is kept in operation by cooperating only with the dispensing head. This means that an empty unit can be used for a micro-diffuser type dispensing head.

The emptying unit can be located on the second part of the dispensing head which is moving in a direction different from the direction in which the product is discharged from the dispensing orifice.
The emptying unit can be located on the area of the moving second part furthest from the dispensing orifice.

In particular, the first part of the emptying unit, which is arranged on the moving second part of the dispensing head, is introduced at this position behind the dispensing orifice. That is, the first part of the emptying unit never touches the plane that touches the dispensing orifice from which the product is discharged and never cuts the plane.
Therefore, when attaching the unit to be emptied, the risk that the user sprays the product on the hand is reduced.

The first part of the dispensing head can be fixed on the container, or alternatively it can be fixed on the valve cup that supports the valve.
The packaging device can comprise a valve cup that supports the valve and is particularly crimped on the container, and the dispensing head surrounds the valve cup so that the valve cup cannot be accessed from the outside.

The emptying unit can be an element separated from the protective cover.
The emptying unit can comprise a wall defined by a top edge, a bottom edge, and two side edges, the wall being curved between the two side edges. , Generally straight between the top and bottom edges. The emptying unit has a simple shape that is easy to produce and handle. The curved shape also means that, in use, the unit can be easily placed on a conventional scatterer having a circular cross section. The curved shape also allows the unit to be placed in a container having a circular cross section without forming an excessively large ridge that significantly increases the volume of the device when packaging the unit.

The bottom edge of the evacuating unit can press against the moving second part of the dispensing head.
The emptying unit can comprise protrusions formed at the ends of the two rods, the top edge of these protrusions contacting the first part of the dispensing head. As described above, the flexibility of the rod that supports the protrusion allows the protrusion to be easily disposed so as to contact the bottom of the wall.

As a variant, the emptying unit can be provided with a shoulder perpendicular to the wall near the edge of its bottom, which shoulder contacts the first part of the dispensing head.
The emptying unit can be secured to the container or dispensing head such that each device comprises an emptying unit prior to first use. The emptying unit is also used when the product is dispensed without using the emptying unit when the user applies a manual pressing force to the moving second part, i.e. when the device is in normal use. It can be fixed to the container or the dispensing head. To this end, the emptying unit can be secured to the container or dispensing head by a protective film that surrounds the device and holds the emptying unit flat against the container or dispensing head. As an alternative, the emptying unit is a container or dispenser by means of two arms holding the container or dispenser head, or possibly by a ring snapped or crimped onto the container and / or dispenser head. Can be fixed to the head. As a further alternative, the emptying unit can be made in one piece with a part of the dispensing head, which is connected to the part of the dispensing head by a bridge of at least one destructible material. The In this case, the unit to be emptied can be accommodated in a slot provided in the first part fixed to the distribution head after being separated from the distribution head.

Thus, the product can be dispensed in the conventional manner without removing the emptying unit from the device, thus reducing the risk of losing the emptying unit before use.
The emptying unit can be provided with a cover designed to face the dispensing orifice when in the emptying position, thereby preventing the spray from spreading into the air when emptying the container. .

  The product contained in the container can be a cosmetic product.

  Another subject of the present invention is a device for product packaging and distribution under pressure separate from or in combination with the device. The device includes at least one container for containing a product, and a top of the container is mounted with a valve and a dispensing head that activates the valve to allow the product to be discharged from at least one dispensing orifice. The dispensing head comprises a first part fixed to the container on the longitudinal axis of the container and a second part for actuating the valve by moving relative to the first part about the axis. The device further comprises an emptying unit, which can take a position in which the valve is maintained in the operating position, in which the dispensing head is moved onto the second moving part of the dispensing head. The part of the emptying unit which is arranged in a direction different from the direction in which the product is discharged from the dispensing orifice and which is arranged above the moving second piece is introduced at this position behind the dispensing orifice Is done. Therefore, there is no risk that the product will stick to the user's finger when the empty unit is attached to the dispensing head.

  The following detailed description of exemplary, non-limiting embodiments, as well as the accompanying drawings, will provide a better understanding of the invention.

1 and 5 represent a dispensing device 10 comprising a container 20 with a dispensing head 30 mounted on the top.
As shown in FIG. 5, the container 20 includes, for example, a pressure can, and the pressure can is provided with a valve fixed to the can by a valve cup 21 that is caulked to the top of the can and seals the top of the can. . This valve has a hollow valve stem 22. The valve can be any known type that is actuated, for example, by pressing the stem.

The container contains the product to be sprayed, such as a cosmetic product, and a propellant delivered with the product, which may or may not be stored in liquefied form within the container.
The distribution head is of the micro diffuser type. That is, the scatterer function and the cover function are integrated. The dispensing head comprises a first part 40 fixed to the can 20 and a second part 50 for actuating the valve by moving relative to the first part about an inclined axis. The outer diameter of the dispensing head is approximately equal to the outer diameter of the can 20 which is cylindrical with its own axis of rotation.

The first part 40 mainly comprises a cylindrical skirt 41 having a circular cross section, forming the side wall of the dispensing head and connected to the top of the transverse wall 42.
A bead 43 is provided at the bottom of the cylindrical hem 41, and this bead allows the hem to snap into the annular groove 23 formed in the top of a can having a significantly smaller diameter. .

An opening 44 is provided in the transverse wall 42 to access the moving second part 50 and actuate the valve. The opening 44 is elongated and has one end defined by two straight edges 44a separated from each other to the periphery of the transverse wall and extending beyond a portion of the height of the cylindrical skirt 41. These two edges 44a merge at the other end, away from the periphery of the transverse wall.
Two internal walls 45 extend perpendicularly from each edge 44a toward the transverse wall 42 and thus parallel to the skirt 41. These inner walls terminate at a free edge 45a.

A shoulder 46 that fits inside the skirt 41 is also provided at the same level as the top edge of the skirt 41 that defines the opening 44.
The cylindrical skirt 41 also has a front opening 47 that passes through the skirt and faces the opening 44, and the distribution orifice 55 opens toward the front opening 47. When the moving part 50 is pressed, the product can be dispensed through this dispensing orifice.

The moving second part 50 is intended to be pressed with the user's finger and thus comprises a top wall forming the working area 51. The working area 51 thus comprises components that are perpendicular to the working stem of the valve. The working area extends vertically downward to close the opening 44, extends into the interior of the skirt 41 and terminates in a lateral shoulder 52.
The internal surface of the working area 51 connects to a duct 53 that defines a channel 54 provided for delivering product from the valve stem 22 to the dispensing orifice 55.

In particular, the duct 53 comprises a cylindrical skirt 56 having a rotational axis that extends generally in the axial direction of the valve stem, the top of which is connected to the working area 51. The bottom of the cylindrical skirt 56 defines a shoulder recess 57, into which the top of the valve stem is fitted, as shown in FIG. This figure also shows that the top end 22a of the valve stem 22 contacts the shoulder 57 of the recess. The skirt 56 defines a first part of the channel 54 that leads the product.
Channel 54 extends along a second part defined by tube 58 that extends laterally from the first part. The tube 58 has an elongated shape along an axis perpendicular to the main axis of the valve stem and extends from the cylindrical skirt 56 through the dispensing orifice 55 to the terminal opening. The dispensing orifice 55 is defined by an associated nozzle 80, for example a conventional nozzle having a spiral channel.

The moving second part 50 of the dispensing head is housed in two orifices and is axially centered on the first part 40 of the dispensing head by two shafts (not shown) rotatable in the orifice. It is hinged. The orifice is formed, for example, in the inner wall 45 of the fixed first part 40 alongside the dispensing orifice.
The packaging and dispensing device 10 shown in FIG. 1 also comprises an emptying unit 60 secured on the container by a protective film 70 in accordance with the illustrated embodiment. The protective film 70 is a shrinkable sleeve that is pressed flat onto the container and dispensing head to protect the device and tighten the emptying unit 60 onto the container.

The emptying unit 60, shown isolated in FIG. 3, comprises a wall 61 with a top edge 62, a bottom edge 63 and two lateral edges 64. The wall 61 is generally straight between the top edge and the bottom edge, while being curved between the two lateral edges to closely fit the curvature of the cylindrical hem 41. . Two vertical slots 66 are provided so that two rods 67 are formed on the side edges of the wall 61. At the end of each rod, a protrusion 65 is provided on the side extension of the wall 61 to form a hook. The upper edge 65a of each protrusion is attached to the fixed first part 40 of the dispensing head. A recess 68 may be provided in each of the side edges 64 of the wall 61 above the slot.
As shown in FIG. 1, the packaging and dispensing device is sold in a state where the unit 60 for emptying the container is fixed by a protective film 70 surrounding the container and the spray orifice 55 is not covered. .

The user can dispense the product as usual multiple times by holding the emptying unit 60 on the container and pushing the actuation area with a finger to actuate the valve and release the product. . There is no risk of losing the unit 60 that is emptied during normal use of the device.
When the product is almost gone and the device is to be discarded, the user can empty the propellant remaining in the container and optionally the rest of the product by using the emptying unit 60. At that time, the user can grasp the unit 60 to be removed by removing the protective film 70. The user places the emptying unit 60 behind the working area 51 of the opening 44 formed in the transverse wall 42, ie close to the skirt 41. The bottom edge 63 of the evacuating unit 60 presses against the shoulder 52 extending from the working area 51 of the moving part 50 of the dispensing head, thereby moving and actuating the valve. The two recesses 68 of the emptying unit then contact the transverse wall 42, thus limiting the depth of insertion of the emptying unit into the dispensing head. Of course, there is no need for such a structure to stop. In this position, the protrusion 65 is located below each inner wall 45 of the first part 40 to which the dispensing head is fixed. As a result, the upper edge 65a of the protrusion 65 is in contact with the bottom edge 45a of the inner wall 45, thereby preventing the return of the second component 50 to which the dispensing head moves. Thus, the moving part 50 stays in the position where the moving second part is depressed, with the valve activated, so that the product and propellant still present in the container can be emptied. Furthermore, the bottom edge 63 of the emptying unit is introduced into the emptying position behind the dispensing orifice. The edge 63 of the evacuating unit never touches the plane P that contacts the orifice from which the product is discharged and never cuts the plane. There is no risk of product sticking to the user's hand when mounting the emptying unit on the dispensing head.

As clearly shown in FIG. 5, the emptying unit 60 is placed on a moving area of the second part that is farthest from the dispensing orifice 55. In addition, the emptying unit 60 is arranged in this area in a state of being oriented in a direction substantially parallel to the axis of the container. That is, it is arranged in a state in which it is oriented in a direction different from the direction in which the product is discharged from the dispensing orifice 55, which is substantially perpendicular to the axis of the container. In this way, the risk of a user getting a product when installing an empty unit is limited.
Of course, the present invention is not limited to the exemplary embodiments described above.

Instead of being fixed on the container by the protective film 70, the emptying unit 60 may be fixed on the container by two arm portions 71 fastened to a part of the periphery of the container, as shown in FIG. The two arm portions 71 can be made as a single unit with the unit to be emptied by connecting to the unit to be evacuated by a bridge made of a destructible material, for example. What is needed here is to separate the arm 71 from the emptying unit before using the emptying unit 60 to empty the container. Again, the user can dispense the product as usual without disturbing the dispensing operation while the emptying unit 60 remains held on the container.
In yet another variation, the emptying unit 60 can be secured to the container by a ring 72 that snaps onto the bottom of the container, as shown in FIG. Again, the ring 72 can be made as a single unit with the unit to be emptied by connecting it to the unit to be evacuated by a bridge of breakable material. Such a ring can also be fixed between the squirter and the container by means of a crimping rather than a snap fit as a variant. As shown in FIG. 7, by selecting a ring having an inner diameter that is significantly larger than the outer diameter of the squirter and significantly smaller than the outer diameter of the container, the ring is fitted around the squirter and is attached to the upper end of the container. Can be slid until crimped. Again, the user can dispense the product as usual without obstructing the dispense without using the emptying unit 60 held on the container.

According to another variant shown in FIG. 11, the emptying unit is initially as a single body with a dispensing head, for example as a single body with a protective knob 74 initially provided above the moving parts of the dispensing head. Can be created. In this case, the emptying unit 160 is connected to the protective knob by a bridge made of destructible material 73, and the protective knob 74 itself is connected by a bridge made of material to the transverse wall 42 of the part to which the dispensing head is fixed. The Prior to first use, the knob 74 and the emptying unit are separated from the dispensing head. According to this embodiment, a slot 48 is provided in the side wall 41 of the dispensing head, and the unit to be emptied throughout the normal use of the device is attached to the device by introducing a unit to be emptied by the user into the slot be able to.
Instead of being made as a single body with the protective knob 74, the emptying unit can be made as a single body with another part of the dispensing head, for example the skirt 41 connected by a bridge made of destructible material. it can. In this case (not shown), the emptying unit does not separate from the dispensing head until the end of normal use of the device, i.e. when it is desired to empty the container. In this case, it is not necessary to provide a slot at the skirt to accommodate the empty unit.

  The emptying unit can have a different shape than that shown in FIG. Specifically, the emptying unit 160, which is located on the dispensing head before the first use in FIG. 11 and shown alone in FIG. 9, is a wall that curves between two side edges 164. 161 and a bottom edge 163 designed to squeeze the moving part 50 of the dispensing head. In this case, a transverse shoulder 165 extending in the lateral direction of the wall 161 is provided between the two lateral edges 164 in the vicinity of the bottom edge 163 of the wall 161. The transverse shoulder 165 is intended to contact the first part of the dispensing head. As specifically shown in FIG. 10, when the emptying unit 160 is in the operating position, the transverse shoulder 165 contacts the shoulder 46 of the fixed part 40 of the dispensing head and the moving part 50 of the dispensing head moves. Prevent return and keep valve in working condition.

According to another embodiment shown in FIGS. 12 and 13, the top end 262 of the emptying unit 260 includes a curved wall 261 that is connected to the annular portion 268 by a transverse wall 269. The annular part 268 is fixed to the skirt part 41 of the component to which the distribution head is fixed in the operating position of the emptying unit. A protrusion 265 is provided at the bottom edge 263 of the wall 261. The protrusion 265 extends laterally from the curved wall 261 without extending beyond the side edge 264, and the distribution head is fixed. It fits under the shoulder 46 of the part. In this position, the bottom edge 263 of the wall 261 presses against the shoulder 52 and actuates the valve. The wall 261 is also provided with a vertical slot 266 that provides two flexible rods 267 that facilitate positioning of the protrusions under the shoulder 46. Instead of the lateral projection 265, as a variant, a projection formed on the lateral extension of the lateral edge 264 may be provided to form a hook as in the embodiment of FIG. Good.
12 and 13, the emptying unit 260 also includes a cover 90 that is installed opposite the dispensing orifice 55 when the emptying unit is installed in the operating position shown in FIG. Prepare. The cover 90 is formed by a wall portion that is the opposite side of the curved wall portion 261 and extends the upper edge of the top portion of the annular portion 268. This cover 90 limits the injection of product and / or propellant into the air when performing the emptying operation. The evacuated product actually flows along the walls that form the cover and then along the container.
Such a cover can also be provided especially in the other embodiments shown in FIGS. 6 to 8, for example by extending one of the arm portions 71 of the emptying unit 60 shown in FIG. A cover may be formed on the opposite side of the unit 60 in the diameter direction.

According to another variant shown in FIGS. 14-16, the emptying unit 360 is initially made as a single unit with the dispensing head, similar to the variant shown in FIG. As shown in FIG. 14, the emptying unit is connected to the transverse wall 42 of the fixed part 40 of the dispensing head by a bridge 75 made of material and extends above the moving part 50 of the dispensing head. The emptying unit 360 shown alone in FIG. 15 comprises a flat wall 361, one end 362 of which terminates at a straight end that connects to the transverse wall 42 of the fixed part 40. The flat wall 361 is generally frustoconical and has a recess 363 that narrows the end 362. On the opposite side of the end 362, the flat wall 361 protrudes outward and terminates at an edge 364 along the cylindrical skirt 41 of the fixed part. The curved wall 365 extends vertically from the flat wall 361 and retreats from the other end 364 toward the inside of the distribution head.
To dispense the product, the user opens the working area 51 by separating the emptying unit 360 from the fixed part 40 of the dispensing head. At the end of use, when it is desired to empty the container, the user can place the narrower end 362 of the flat wall 361 of the emptying unit 360 in front of the working area 51, ie behind the nozzle 80. Arranged in an opening 44 formed in the transverse wall 42. When placed in this position shown in FIG. 16, the bottom surface 362a of the end 362 compresses the moving portion 50 of the dispensing head and moves the valve to actuate. The upper surface 362b of the end 362 contacts the transverse wall 42 of the part 40 to which the dispensing head is fixed, so that the emptying unit holds the moving part 50 pressed. Advantageously, by increasing the thickness of the edge of the narrower end 362, the risk of the emptying unit not leaving the emptying position is further reduced.

Again, the end 362 of the emptying unit is introduced behind the dispensing orifice without contacting the plane P that contacts the dispensing orifice from which the product is discharged. Therefore, there is no possibility that the product will be attached to the user's finger when the empty unit is attached to the distribution head.
In the foregoing detailed description, reference has been made to preferred embodiments of the invention. Of course, variations can be made thereto without departing from the scope of the invention as defined in the claims.
