Description

Device for packaging a refill of a product

The present invention relates to a device for packaging a product refill, in particular a cosmetic product.

More particularly, the packaging device according to the invention comprises a sheath having an open end and a removable assembly adapted to be removably attached to the open end of the sheath between a locked position in which the refill is retained in the sheath and an unlocked position in which the refill can be extracted from the sheath.

Devices of this type are known, in particular for refills of cosmetic products that may be of the vaporizer, pump or bottle type. In recent years, especially in the cosmetics field, this type of refill has been developed with the aim of reducing the manufacturing costs of packaging of cosmetic products, and their impact on the environment.

There is therefore a growing need for the existing packaging to be gradually replaced by packaging devices hosting the cosmetic product refill, in which case, when the cosmetic product has been used, the packaging device itself can be preserved. , only the refill being thrown away. Once the recharge is empty, it is sufficient for the user to unlock the removable assembly of the open end of the sleeve and extract the refill to place a new or different. It is important, however, that, on the one hand, the conditioning device has the aesthetic qualities required by the user and that, on the other hand, the manipulations of replacement of an exhausted refill are as simple as possible for the user.

Thus, the type of packaging device must be easy to use and must allow easy extraction of the refill it contains and an easy introduction of a new refill, that is to say requiring little effort and attention on the part of the user. The packaging device must also allow easy locking of the removable assembly to the open end of the sleeve. In addition, the maintenance of the refill in the conditioning device must be reliable, that is to say that the removable assembly does not go into unlocked position inadvertently.

Packaging devices for a refill of a product are known from US Pat. No. 3,080,989, in which the removable assembly comprises an activation element retained in the sheath which is provided with elastic tabs protruding from the open end of the sheath. The removable assembly further comprises a retaining cap having two lumens, arranged on the sheath so that the bulges of the elastic tongues of the activation element cling into the lumens of said cap. In order to change the recharge, it is sufficient for the user to press the tabs of the activation piece so that they disengage the cap, the latter can then be removed from the open end of the sleeve. Conversely, to replace a new refill in the conditioning device, the retaining cap has to be put in place until again engaging the bulges of the elastic tongues in the lights of said cap.

These manipulations, including the support on the tabs, may require a relatively large effort to disengage the tabs of the lights. Conversely, if the effort to be exerted on the tabs to disengage is small, there is a risk that the tabs disengage the lights in an undesired manner. Moreover, it is possible that after multiple manipulations of the tongues, their joints soften and that the tabs do not lock in the bulges.

Moreover, this conditioning device is unreliable because during handling of the packaging device, it is possible that the user inadvertently presses on the bulges of the tabs, causing their accidental disengagement of the lights of the cap.

In addition, the overall appearance of this packaging device is relatively unattractive because of the lower part of the particularly visible retaining cap.

An object of the present invention is to substantially remedy the aforementioned drawbacks. This object is achieved thanks to the fact that the removable assembly comprises a retaining interface, which cooperates with the open end of the sheath and which has an anchoring member, and an activation member which cooperates with the retaining interface being able to be displaced axially with respect to it, the activation member being thus able to be brought by an axial displacement with respect to the retaining interface into an activation position in which the activation member solicits the anchoring the anchor member to the open end of the sleeve and a disengaging position in which it releases the anchoring member and allows the disengagement of the removable assembly of the open end of the sleeve.

It is understood that to anchor or disengage the anchor member of the open end of the sleeve, it is sufficient for the user to press the activation member in the axial direction. Thus, when the activation member reaches its activation position, the removable assembly is locked at the open end of the sleeve, and the refill is held in the sleeve.

When the removable assembly is in the locked position, the user can use the refill as if he had it directly in the hands. It is therefore understood that the conditioning device does not interfere with the distribution element of the refill.

In addition, the movement for anchoring or releasing the anchoring member being axial, a large choice is offered as to the aesthetics of the device, which does not necessarily have radially projecting parts.

The refill can be of the type having a neck, which is for example the case when it comes to a bottle. In this case, the removable assembly can be arranged around this neck. The refill has a handling element, for example a spray head, a stopper or the like. In this case, the removable assembly is arranged such that the handling element protrudes from the removable assembly.

The conditioning device according to the invention is therefore reliable because there is little risk for the activation member to move axially in an undesired manner, in particular when the user manipulates the handling element of the refill for allow the use of the product it contains. In addition, when the user enters the device of conditioning at the sleeve, the fingers of the user are not within the reach of the activation member, which prevents accidental unlocking of the removable assembly.

When the activation member reaches its disengaged position, the removable assembly is unlocked from the open end of the sheath and can be removed from the open end of the sheath. The user can then remove the used refill from the scabbard and replace it with a new refill.

The packaging device according to the invention is particularly simple and intuitive to use. It suffices here for the user to push the activation member by means of its two inches, for example, to lock or unlock the removable assembly of the open end of the sleeve.

In some embodiments, the removable assembly forms a unitary assembly.

Here we understand by "unitary unit" that the removable assembly forms a whole. Thus, when the activation member is unlocked from the open end of the sleeve, the user removes the removable assembly from the open end of the sleeve in one go, without any part of this set remaining in place on or in the scabbard. These arrangements facilitate the locking and unlocking of the removable assembly and prevent the user from mislaying a piece of the removable assembly.

In some embodiments, the detachable assembly further comprises biasing means able to urge the movement of the activation member towards its disengaged position after an axial displacement of said member from its position. activation.

Advantageously, the biasing means are disposed between a bottom of the retaining interface and the activation member.

These arrangements further facilitate the handling of the conditioning device for the passage of the activation member from its activation position to its disengagement position.

In certain embodiments, said axial displacement of the activation member from its activation position is achieved by a thrust of said member towards the inside of the sleeve (ie in the direction of the bottom of the sleeve), and the axial displacement of said member organ to its disengagement position is achieved by a thrust of said organ into a direction of exit of the sheath (ie in the opposite direction to the bottom of the sheath).

It is understood that to unlock the removable assembly of the open end of the sleeve, the user presses the activation member towards the inside of the sleeve while maintaining the sleeve, so that the body of activation compresses the means of solicitation. Once the user stops pressing the activation member, the biasing means are "released" and push the activation member in the output direction of the sleeve, which reaches its disengagement position.

Advantageously, the biasing means comprise a spring.

It can be a coil spring simple to manufacture and inexpensive.

In some embodiments, one of the activating member and the retaining interface comprises a follower pin which cooperates with at least one heart-shaped cam integral with the other member of the body member. activation and the retaining interface, said cam defining a heart path for the pawn.

The operation of the heart-shaped cam is known in itself.

In the example, the heart-shaped cam defines at least two stable positions of the follower pin in the heart path, one of the stable positions corresponding to the position of the activation member in the activation position, and the another stable position corresponding to the position of the activation member in its disengagement position. The transition from one to the other stable positions is effected by an axial displacement of the activation member relative to the retaining interface.

In some embodiments, the follower pin is provided on a leg of one of the holding interface and the activating member. For example, the follower pin is formed on a free end of said tab.

In some embodiments, the retaining interface has at least one anti-loosening stop disposed opposite the tab so as to prevent the withdrawal of the tracking pin from the core path.

Thanks to these provisions, the follower pin remains correctly in position in the heart course and is not likely to emerge. So, these provisions can further enhance the reliability of the packaging device.

In some embodiments, the anchoring member comprises at least one projection, in particular a rib, adapted to cooperate with at least one recess, in particular a groove, formed in the wall of the sleeve when the activation member reaches its activation position.

It is understood that when the activation member reaches its activation position, the projection of the anchor member "hangs" in the recess in the wall of the sleeve. With these provisions, the removable assembly is reliably locked to the open end of the sleeve. To further enhance the reliability of the conditioning device so that the user avoids "unhooking" the protrusion of the recess, the latter may not be through (ie do not take the form of a window), which can allow a large freedom of choice as to the aesthetics of the device.

Advantageously, the anchoring member may comprise a tongue on which is formed the projection.

According to a preferred possibility, the tongue is disposed inside the sheath and the projection is disposed on the face of the tongue which is oriented towards the wall of the sheath, that is to say vis-à-vis the recess in the sheath.

In some embodiments, the activation member comprises at least one bearing surface capable of pushing the tongue towards the wall of the sleeve to anchor the anchor member to the open end of the sleeve.

During the axial displacement towards the bottom of the sheath of the activation member with respect to the retaining interface, the bearing surface of the activation member progressively pushes the tongue of the anchoring member into position. direction of the sheath into a position in which the projection of the tongue is engaged in the recess in the wall of the sheath.

In some embodiments, the tongue is elastic, and has a natural position that does not allow anchoring of the anchor member to the open end of the sleeve. For example, in this natural position, the tongue is inclined towards the axis of the device, so that the external diametrical dimension of the projection is less than that of the recess. When the tongue is not subjected to the pressure exerted by the bearing surface of the activation member, said tongue resumes itself its natural position, which causes the release of the anchor member of the sheath.

In some embodiments, the retaining interface and the activating member cooperate together by longitudinal guiding surfaces.

These arrangements make it possible to ensure the axial displacement of the retaining interface and of the activation member relative to one another, while preventing their relative rotation.

The invention also relates to a packaging assembly comprising a product refill and a packaging device as described above, wherein the removable assembly is arranged around the neck of the refill and / or a handling element of said refill.

A packaging assembly of a refill of a cosmetic product according to the invention is described with reference to FIGS. 1A to 9.

The packaging assembly comprises a packaging device 200 and a refill 100 of a cosmetic product. According to the invention, the conditioning device 200 comprises a sheath 202 having an open end 204 and a bottom 206 opposite this end 204.

The refill 100 forming here a vaporizer comprises a neck 102 and a push button type of handling element 104. The refill 100 is received in the sheath 202 and can be placed in abutment against an internal lining such as a foam 206a arranged at the bottom 206 of the sheath 202. The foam 206a makes it possible to damp the shocks between the refill 100 and the bottom 206 sheath 202, and properly stall the refill 100 in the sheath 202. The sheath 202 further comprises a lower casing 208a. Comparing FIGS. 1A and 9, it can be seen that the packaging device 200 according to the invention comprises a removable assembly 20 adapted to be removably attached to the open end 204 of the sheath 202 between a locked position in which the refill 100 is retained in the sleeve 202 (see Figure 1A) and an unlocked position in which the refill 100 can be extracted from the sleeve 202 (see Figure 9). In particular, the removable assembly 20 is arranged around the neck 102 and the handling element 104 of the refill 100.

It can be seen in FIG. 1B that the conditioning device 200 may comprise a cap 210 comprising an inner wall 212 and an insert 214 defining a housing 216 between said insert 214 and the inner wall 212. If necessary, a ballast may be arranged in said housing 216. In addition, the inner wall 214 of the cap 210 is housed in an upper housing 208b.

The axis A of the conditioning device is defined as being the longitudinal axis of the conditioning device 200.

Referring to FIGS. 1A to 4 and 9, it can be seen that the removable assembly 20 comprises a retaining interface 50 comprising an anchoring member 30 adapted to be anchored to the open end 204 of the sleeve 202, and a Guiding 40. The anchoring member 30 and the guiding member 40 are permanently clipped to each other.

Referring to FIGS. 5A and 5B, it can be seen that the removable assembly 20 further comprises an activating member 60 adapted to be axially displaced along the axis A with respect to the holding interface 50, being guided by the guiding member 40 and subjected to the thrust of a spring 52 arranged between the retaining interface 50 and the activation member 60. By this means, the activation member 60 can be brought relative to the holding interface 50 in an activation position in which the activation member 60 urges the anchoring of the anchoring member 30 to the open end 204 of the sleeve 202, and a disengagement position in which it releases the anchoring member 30 from the open end 204 of the sheath 202. Thus, to lock or unlock the removable assembly 20 of the open end 204 of the sheath 202, it is sufficient for the user to press the activation member 60 in the direction of the sleeve 202, while maintaining the sheath. The removable assembly 20 will be described in more detail with reference to Figures 2A-5B.

As shown in Figures 2A and 2B, the anchoring member 30 comprises a pierced plate 32, which in this case has a generally parallelepiped shape delimiting a generally ellipsoidal opening 34. As can be seen in particular in FIGS. 1A and 1B, the shape and the dimensions of the plate 32 are adapted to the shape and the dimensions of the open end of the sheath 202, so that the plate 32 bears on the open end 204 of the sleeve 202 and the opening 34 of the plate is coaxial with the axis A with the opening of the sleeve 202. In the example, the shape and dimensions of the opening 34 and those of the opening of the sheath are substantially the same.

The anchoring member 30 further comprises clipping tabs 36 in the inner wall of the sleeve 204, in this case four here, regularly distributed circumferentially along the opening 34. Each of the clipping tabs 36 comprises on its face facing the inner wall of the sleeve 202 a clipping rib 36a adapted to cooperate with grooves 208 formed in the inner wall of the sleeve 202 when the removable assembly 20 is in the locked position at the open end 204 of the sleeve 202. As can be seen in FIGS. 1A and 1B, because of their natural elasticity, the clipping tongues 36 are naturally oriented radially in the opposite direction to the wall of the sheath 202, so that the ribs 36a of the tongues 36 escape the grooves 208. formed in the inner wall of the sleeve 202 when the removable assembly is unlocked from the open end of the sleeve.

With reference to FIGS. 3A and 3B, it can be seen that the wall 40 'of the guide member 40 is generally tubular and comprises four openings 43. When the guide member 40 and the anchoring member 30 are clipped together, to one another, the openings 43 are opposite the clipping tongues 36 of the anchoring member 30. The dimensions and the shape of the openings 43 are adapted to the dimensions and to the shape of the clipping tabs 36 of the anchoring member 30.

The guide member 40 further comprises a bottom 42 facing the bottom 206 of the sleeve 202, in which an opening 42a is formed. The guide member 40 further comprises heart-shaped cams 44, in this case two which are diametrically opposed to one another. Each of the core-shaped cams 44 is formed on an axial wall portion 40 "projecting in the axial direction A from the bottom 42 of the guide member 40. The two portions 40" are arranged on the bottom 42 recessed from the wall 40 'of the guide member 40, in the direction away from the wall of the sleeve 202.

Each heart-shaped cam 44 has a core path 45 opposite the wall of the sleeve 202, said core path 45 being "hollowed" in the portion 40 "around a guide element 46" in relief with respect to the core path 45. Note that the wall 40 'of the guide member 40 further has two openings 48 vis-à-vis the cams 44 in the shape of a heart.

As can be seen in FIG. 4, anti-loosening abutments 38 are provided on the anchoring member 30 so as to be positioned opposite the heart paths 45 of the heart-shaped cams 44 when the anchoring member 30 and the guide member 40 are clipped to each other. Each anti-loosening abutment 38 is arranged on the edge of the opening 34 of the plate 32 and extends downwards in the axial direction A. The stops 38 are connected to the plate 32 of the anchoring member 30 by a connecting arm 38a.

The anchoring member 30 and the guiding member 40 are clipped to each other by cooperation of recesses 39 formed in the anchoring member 30, with ribs 41 formed on the outer wall of the Guiding member 40. In the example, there are six ribs 41 and six recesses 39. As seen in Figure 4, once attached to each other, the anchor member 30 and the guide member 40 form the retaining interface 50.

With reference to FIGS. 5A and 5B, it can be seen that the activating member 60 comprises a tubular support portion 62 extending through a tubular base 64, the bearing portion 62 and the base 64 being connected to each other. the other by a radial connecting portion 66.

The activation member 60 has guide grooves 64a adapted to cooperate with ribs 47 formed on the inner wall of the guide member 40, to guide the axial displacement of the activation member 60 with respect to the restraint interface while preventing their relative rotation. In the example, there are four guide grooves 64a and four ribs 47. In a variant, the activation member 60 could comprise the ribs 47, and the guide member 40 the guide grooves 64a.

Referring to FIGS. 1A and 1B, it can be seen that the bearing portion 62 of the activating member may be dressed with crimping 70. An additional crimping 80 may be arranged on the retaining interface 50. It should be noted in particular that crimping 80 comprises a tubular lateral portion 82 adapted to the dimensions of plate 32 and a tubular central portion 84 surrounding crimping 70 which is shaped so as not to interfere with the axial displacement of activation member 60 and also promote the clipping of the upper case 2008b.

The activating member 60 further comprises flexible tabs 68, in this case two here, the free end of each of these tabs 68 being provided with a follower pin 68a able to cooperate with each of the runs 45 heart-shaped cams 44 when the activation member 60 is mounted on the retaining interface 50.

Preferably, the flexible tabs 68 are slightly inclined radially in the opposite direction to the wall of the sleeve 202, so that the follower pins 68a exert a radial force on the heart-shaped cams 44, and naturally tend to be engaged in the hearts 45 heart-shaped cams 44.

Note that the face of the flexible lugs 68 oriented in the direction opposite to the wall of the sheath has a lug 68b adapted to be positioned in abutment against the anti-loosening stops of the anchoring member 30. In the activation position, the tabs 68 are arranged against the inner faces of the anti-loosening abutments, which prevent the lugs 68a from being detached from the cams in the shape of a heart.

As can be seen in FIGS. 1A and 1B and 9, after the spring 52 has been placed in abutment on the bottom 42 of the guide member 40, the activation member is partly inserted into the interface of FIG. retained 50 so that the guide grooves 47 of the guide member 40 are engaged in the ribs of the activation member 60, and that the follower pins 68a are engaged in the heart paths 45. Thus, when the removable assembly 20 is mounted, the spring 52 exerts a push on the activation member 60 directed in the opposite direction to the bottom 206 of the sleeve 202.

As can be seen in FIGS. 5A, 5B and 8A, the base 66 of the activating member 60 has on its outer surface bearing surfaces 69, in this case eight, capable of cooperating with the tongues of FIG. clipping 36 of the anchoring member 30 so as to push these tongues in the direction of the sheath 202 when the activation member 40 reaches its activation position, so that the ribs 36a cling in the grooves 208 of the sheath 202 (see more particularly Figures 6 and 8A).

The heart-shaped cam 44 as well as the cooperation of the follower pin 68a with the core path 45 will be detailed with reference to FIG. 7.

The heart path 45 of each of the heart-shaped cams 44 has the shape, in this example, of an inverted heart, pointing upwards. The core path 45 is dug in the portion 40 "of the guide member 40, forming a guide member 46 of the follower pin 68a in said heart path 45, which is" raised. The guide element 46 has a first ramp 46a which is inclined in the direction of the bottom 206 of the sleeve 202 relative to the direction of movement of the follower pin in the heart path 45, and a second ramp 46b inclined in the opposite direction to the bottom the sleeve 202 relative to the direction of circulation of the tracking pin 68a in the heart path 45.

In this example, the heart path 45 has a "tip" 451, a first lobe 452, and a second lobe 453, and delimits an activation track 454, a disengagement track 455, and a joining portion 457 between the track 455. activation 454 and the disengagement track 455. The joining portion 457 includes a first pan 457a and a second pan 457b.

The core course 45 further has an upper stop 458 formed in the tip of the heart and a lower stop 459 formed by the second ramp 46b of the guide element 46. The first section 457a of the heart course 45 then extends lower end of the first lobe 452 to the lower stop 459, and the second end 457b extends from the lower stop 459 to the lower end of the second lobe 453.

It can be seen in FIG. 3b that each of the portions 40 "of the guide member 40 has at its upper end a groove forming a ramp 441 which extends to a shoulder oriented towards the bottom 206 of the sleeve 204 and opens into the heart path 45 at the tip 451 of said heart path 45. This shoulder corresponds to the upper stop 458 of the heart path 45. It should be noted in this regard in FIGS. 1A and 1B that the follower pin 68a may comprise at its free end a chamfered portion 68c facilitating the passage of the follower pin 68a in the groove 441 of the heart-shaped cam 44 when of the assembly. During the assembly of the activation member 60 and the guide member 40, the follower pins 68a are presented at the top of the ramps 441. A push of the activation member downwards bends the legs 68 until the pins 68a cross the ramps 441 and arrive in the cams in the shape of a heart. Under the effect of the spring 52, each follower pin locks against the upper stop 458 of the heart path 45. The upper stop 458 also acts as a non-return passage of the follower pin 68a in the ramp 441 of the portion 40 ".

The heart-shaped cam 44 defines four particular positions of the follower pin 68a in the heart path 45. A first stable position PSI of the follower pin 68a corresponds to the disengagement position of the activation member 60. In this first stable position PSI, the follower pin 68a is blocked in the heart path 45 against the upper stop 458 under the effect of the thrust of the spring 52.

A second stable position PS2 of the follower pin 68a corresponds to the activation position of the activation member 60. In this second stable position, the follower pin 68a is blocked in the core path 45 by the lower stop 459 under the effect of spring 52.

A first unstable position PII of the follower pin 68a is defined beyond the first stable position PSI in the lower end of the first lobe 452, after the follower pin 68a has been moved towards the bottom 206 of the sleeve 202 since its first stable position PSI. This manipulation has the effect of compressing the spring 52.

A second unstable position PI2 of the follower pin is defined beyond the second stable position PS2, in the lower end of the second lobe 453, after the follower pin 68a has been moved toward the bottom 204 of the sleeve 202 since its second position. PS2 stable position. This manipulation has the effect of compressing the spring 52. As shown in FIG. 1A, when the removable assembly 20 is locked at the open end 204 of the sleeve 202, the activation member 60 is in the activation position. As seen previously, in this activation position of the activation member 60, the follower pin 68a is locked in the second stable position PS2 by the lower stop 459 under the effect of the spring 52 which exerts pushing the activation member in the opposite direction to the bottom 206 of the sleeve 202. Thus, as shown in FIGS. 6 and 8A, in the second stable position PS2 of the follower pin 68a, the bearing portions 69 of FIG. the activation member 60 push the clipping tongues 36 radially towards the inner wall of the sheath 202 so that the ribs 36a of the tongues 36 catch in the grooves 208 of the sheath 202.

To unlock the removable assembly 20 of the open end 204 of the sleeve 202, the user bears on the bearing portion 62 of the activation member 60 towards the bottom 206 of the sleeve 202. This has the effect of moving the tracking pin 68a in the second pan 457b of the heart path 45, to the second unstable position PI2. When the user stops pressing the support portion 62, the activation member 60 is pushed in the opposite direction to the bottom 206 of the sleeve 202 under the effect of the thrust exerted by the spring 52. This causes moving the follower pin 68a in the disengagement track 455 to the first stable position PSI in which the activation member is in its disengaged position.

As can be seen in FIG. 8B, in the disengagement position of the activation member 60, the clipping tabs 36 of the anchoring member 30 are no longer subjected to the pressure exerted by the bearing portions. 69 of the activation member 60 and, because of their natural elasticity, fold in the opposite direction to the wall of the sheath 202. The user can remove the removable assembly 20 of the open end 204 of the sheath 202, as shown by the arrow E in FIG. 9.
