Description

Rechargeable packaging for cosmetics

The present invention relates to a packaging device for at least one cosmetic article of a type comprising a base element and a refill removably mounted to the base element, the base element comprising a support having a cavity formed, the refill being contained within the cavity. A receptacle, the receptacle having an interior storage compartment for a first cosmetic article opened through the access opening to the outside of the receptacle, the packaging device being a cap, the cap being a receptacle in which the cap closes the access opening. And the cap may be displaced relative to the receptacle between the closed position of the receptacle and the open position of the receptacle to release the access opening—and an additional cooperating member to securely retain the refill in the base element.

The term "cosmetic article" according to the invention means a cosmetic intended to be applied to the human body, such as a solid, liquid or cream such as powder. More generally "cosmetic" means a product as defined in EC Regulation No. 1223/2009 of the European Parliament and of the Council on Cosmetics on November 30, 2009.

The term "cosmetic article" also means a tool used to apply cosmetics on the body surface, which is, for example, a brush, a touch-up brush or a sponge. The "cosmetic article" may also be a beauty treatment tool such as a nail file.

The packaging device is suitable for receiving and moving cosmetic items in consideration of their storage, marketing and use. The packaging device is, for example, a case or box suitable for being accommodated in a handbag. This includes in most cases a base and a lid, which generally has a mirror for monitoring the application of the cosmetic on its inner surface.

If the cosmetic article is a cosmetic, it is advantageous to be able to refill the box if the cosmetic is exhausted. In order to package the product directly in the receptacle, it is known that the base consists of two removable parts with respect to each other, one of which receives the refill receptacle.

If this cosmetic is a fluid or powder product type, it is advantageous to close the refill receptacle tightly with a cap. Therefore, there is no possibility that the product will contaminate the inner surface of the lid.

This packaging box is described in particular in document FR 3 036 595.

A common problem with this type of packaging device is that the cap must be provided in a closed position to securely seal the refill receptacle and the cap, and considerable effort is required to open it. However, in order to prevent the refill receptacle from being pulled out of the box by opening the refill receptacle, it is necessary to provide a device for holding the refill, which means that a greater output force is required than the force to open. . As a result, withdrawing refills out of the box is often a difficult task for the user.

It is therefore an object of the present invention to facilitate the method of separating the refill receptacle from the box of the packaging device. Another purpose is to ensure good sealing of the refill receptacle when the box is closed.

To this end, it is an object of the present invention to provide a packaging device of the type described above, wherein the cap is itself self-closed from its closed position when a lifting force is applied on the cap that is greater than the first threshold value. Can be displaced to an open position, and the additional cooperating member can counter the separation of the refill for the base element if the pull force applied to the refill is less than the second threshold, and the pull force is greater than the second threshold value. If large, it may allow separation of refills for the base element, the second threshold being strictly larger than the first threshold, and the first threshold being 3 Newtons or less.

These two parts 110, 112 are separated from each other by an annular protrusion 108.

The first portion 110 defines a first housing that houses the first cosmetic article 113 (FIG. 2). This first cosmetic article 113 is, for example, a cosmetic makeup and / or care product such as a powder or cream that is intended to be applied on the surface of the body. Advantageously, the first cosmetic article 113 is a foundation.

Receptacle 82 further includes a peripheral skirt 114 extending from outer peripheral edge 116 of top wall 88. This peripheral skirt 114 protrudes from the outer peripheral edge 116 substantially along the Z direction in the direction of the bottom portion 86 of the receptacle 82. Ends with a free edge 118 contained within the plane (X, Y), the distance from this plane to the outer shoulder 102 is substantially equal to the distance from the shoulder 54 to the top wall 60 of the support 16. .

In the embodiment shown, the receptacle 82 is formed of the lower portion 120 and the upper portion 122 assembled in a removable manner. The lower portion 120 is formed by the bottom portion 86 as well as by the inner portion 124 of the first section 96 of the peripheral wall 89. The upper portion 122 is not only an outer portion 126 of the first section 96 of the peripheral wall 89, but also a second section 98, an annular protrusion 108 and a peripheral skirt 114 of the peripheral wall 89. It includes.

The inner portion 124 is assembled to the outer portion 126 by snap fitting, alternatively by screwing in the embodiment shown to form the first section 96 of the peripheral wall 89. Thus, bottom portion 86 is integrally formed with the rest of receptacle 82.

According to an alternative, not shown, receptacle 82 is a monoblock. The lower portion 120 and the upper portion 122 are then monolithic.

The receptacle 82 is received in the cavity 40 of the support 16 with the axis 92 coinciding with the axis 44. The outer shoulder 102 of the receptacle 82 is supported by the shoulder 54 of the support 16, and the outer surface 104 of the bottom 86 of the receptacle 82 has the bottoms 86, 106 facing the continuous surface. It is flush with the outer surface 106 of the bottom 20 of the support 16 to form. Thus, the receptacle 82 and the support 16 form the base 128.

The cap 84 is centered on the two axis of rotation 132 between a closed position where the cap 84 closes the opening 94 and a released position where the cap 84 releases the opening 94. It is mounted rotatably on the receptacle 82. To this end, the cap 84 includes a plate 130 articulated to the receptacle 82 by a hinge 134 that specifies the second axis of rotation 132.

The second axis of rotation 132 is particularly oriented along the X direction. Therefore, it orthogonal to the 1st off-axis rotation axis 56.

The cap 84 is released from its closed position 500 when a lifting force is applied to the cap 84 on the cap 84 from the outside of the device 10 toward the opposite side of the receptacle 82. ), The lifting force is greater than the first threshold of 3 Newtons or less.

The cap 84 also includes a sealing system 136 to provide a seal between the plate 130 and the receptacle 82 when the cap 84 is in the closed position.

Plate 130 is a monoblock. It is centered on axis 138 to coincide with axis 92 when cap 84 is in the closed position.

The plate 130 includes a peripheral portion 140 having a shape and dimensions similar to that of the top wall 88 of the receptacle 82. In particular, the peripheral portion 140 has a substantially circular contour.

When the cap 84 is in the closed position as shown in FIG. 4, the peripheral portion 140 is disposed in the plane (X, Y).

A portion of the hinge 134 is formed on the one end 141 of the peripheral portion 140 in the peripheral portion 140.

Plate 130 also has axis 136 relative to peripheral portion 140 such that when cap 84 is in the closed position, it is retracted toward the inside of receptacle 82 with respect to peripheral portion 140. A central portion 142 offset accordingly.

Thus, the plate 130 is formed with a central housing 144 centered on the axis 138. This central housing 144 is for receiving a second cosmetic article (not shown), typically consisting of an applicator, for example a sponge 42, adapted to apply a cosmetic contained within the first housing 110. .

The central housing 144 is bounded by an annular boss 146 extending from the peripheral portion 140 to the opposite side of the central portion 142. Notches (not shown) are formed in the boss 146 to facilitate the holding of the second cosmetic article. The upper end portion 147 of the plate 130 is formed in the annular boss 146.

The sealing system 132 connects the rigid wall 150 and the peripheral edge 153 of the rigid wall 150 to the plate 130, which is substantially flat and parallel to the peripheral portion 140 of the plate 130. Flexible annular wall 152.

Rigid wall 150 is substantially discoid. This is the edge 158 that forms a junction between the top surface 154 facing the plate 130, the bottom surface 156 opposite the plate 130, and the top surface 154 and the bottom surface 156 around the wall 150. Has Each of the top surface 154 and the bottom surface 156 has a central recess 160 such that the center of the rigid wall 150 is thinner than its peripheral edge 153. Annular groove 162 is disposed within edge 158.

In the illustrated embodiment, the bottom surface 156 of the rigid wall 150 is smooth and flat. According to a first alternative embodiment (not shown), the bottom surface 156 includes spikes or rough areas. According to a second alternative embodiment (not shown), the lower surface 156 includes decorations and text. According to a third alternative embodiment (not shown), the lower surface 156 comprises a housing for a third cosmetic article, the third cosmetic article being for example a product housed in the first housing 110. A second cosmetic is the same in nature but different in color.

Rigid wall 150 is centered on axis 138. It is arranged to be received in the second portion 112 of the storage compartment 90 when the cap 84 is in the closed position.

The annular wall 152 has the shape of an annular portion of a circular section of diameter whose receptacle 82 is close to the inner diameter of the second section 98 of the peripheral wall 89 in the resting position.

The annular wall 152 may also be elastically deformed in the plane passing through the axis 138. To this end, the annular wall 152 is preferably formed of an elastically deformable material such as, for example, SEBS, or nitrile rubber (NBR), or a thermoplastic elastomer such as silicone. The annular wall 152 also has a curvature in the plane through the axis 138, with the convex portion of the curvature facing the opposite side of the axis 138. As such, the annular wall 152 may increase in diameter under the action of the rigid wall 150 and the plate 130 approaching each other.

The first edge 164 of the annular wall 152 is engaged with the groove 162 and the second edge 166 on the opposite side is, for example, overmolded and fixed to the peripheral portion 140 of the plate 130. do.

When the annular wall 152 is in its rest position, the rigid wall 150 is at a first distance along the axis 138 from the peripheral portion 140 of the plate 130, and the upper end 147 of the plate 130. Is along the axis 138 at a second distance.

This first distance is greater than the distance between the shoulders 100 and the planes X, Y passing through the hinge 132. As such, when the cap 84 is in its closed position, as can be seen in FIG. 4, the rigid wall 150 is supported by the inner shoulder 100 and is closer to the plate 130 and thus the sidewalls. 152 is compressed and the diameter of the annular wall 152 is increased, so that the annular wall 152 is in contact with the peripheral wall 89 of the receptacle 82. As such, the outer surface of the annular wall 152 has the function of a seal that makes intimate contact with the peripheral wall 89 of the receptacle 82.

Also, the second distance is greater than the distance between the shoulder 100 and the inner surface of the lid 18 when the lid 18 is in the closed position. As such, when the lid 18 is in the closed position, the lid urges the plate 130 so that the cap 84 is securely held in the closed position and the annular wall 152 is in a compressed state. Is maintained at to ensure good sealing between the cap 84 and the receptacle 82.

The cap 84 is preferably molded by first injection of the plate 130 and the rigid wall 150, followed by injection of the annular wall 152. Alternatively, plate 130, rigid wall 150 and annular wall 152 are assembled separately and then assembled.

Refill 14 also includes an element 168 for connecting cap 84 to receptacle 82. These connecting elements 168 include a hinge 134. In the embodiment shown, they also include retaining device 170 with cap 84 in a closed configuration.

The retaining device 170 can resist displacement of the cap 84 away from the receptacle 82 when the lifting force applied on the cap 84 is less than the first threshold, The cap 84 allows displacement in a direction away from the receptacle 82 when the applied lifting force is greater than the first threshold. This lifting force must be applied to the side end 172 of the plate 130 on the opposite side of the hinge 132.

To this end, the retaining device 170, in the illustrated embodiment, is formed by a system for snap fitting the plate 130 to the receptacle, the system being hooked to the side end 172 of the plate 130. 174, and a notch 176 formed in the top wall 88 of the receptacle 82 may cooperate with the hook 174. By the spring action provided by the compression of the side wall 152 when the cap 84 is in the closed position, it is sufficient to apply a very weak lifting force to cause the cap 84 to open. As such, opening of the receptacle 82 is possible with a lifting force of 3 Newtons or less.

It should be noted that the constraint of having a first threshold of 3 Newton or less may be followed by a retainer 170 other than that described herein.

Alternatively, the refill 14 does not include any device for keeping the cap 84 in the closed position. The element 168 for connecting the cap 84 to the receptacle 82 is constituted only by the hinge 134. In addition, the cap 84 may be displaced from its closed position to its released position without a lower limit of lifting force to be applied on the cap 84 to cause displacement of the cap, and the first threshold value. Is 0 Newtons.

In order to measure this first threshold, a nacelle, a nacelle mounted movably on a column, between the stand, a column fixed to the stand, a closed position of the stand and a position separated from the stand, the nacelle with its closed position A measuring device is used that includes an actuator for displacing between its separate positions, a hook integral with the nacelle, and a dynamometer for measuring the tensile force acting on the hook. The packaging device 10 is in a position where the lid 18 is open, the refill 14 is inserted into the support 16, and the cap 84 is closed so that the support 16 is fixed to the stand of the measuring device. In this position, it is installed in this measuring device. The hook of the measuring device is hooked to the side end 172 of the plate 130, and the actuator is configured to drive the displacement of the nacelle at a speed of 155 to 175 mm / min. Finally, the actuator is actuated and the tensile force applied to the hook is measured using a dynamometer until the cap 84 is opened under the influence of the force exerted by the hook. The first threshold value consists of the maximum force measured by the dynamometer before the cap 84 is opened.

Base element 12 and refill 14 also include additional cooperating members 180, 182 to securely retain refill 14 in base element 12. These additional cooperating members 180, 182 are drawn along the Z direction from the bottom 20 of the support 16 to the orifice 42 on the outside of the packaging device 10 on the refill 14 (second Less than the threshold value) can be countered by the separation of the refill 14 with respect to the base element 12, and the base element (if the pull force applied on the refill 14 is greater than the second threshold value). It may allow for the separation of the refill 14 to 12). The second threshold is certainly greater than the first threshold to prevent attempts to open the refill 14 to cause ejection of the refill 14 out of the base element 12.

Referring to FIG. 5, additional cooperating members 180, 182, in the illustrated embodiment, form a system for snap fitting within base element 12. To this end, additional cooperating members 180, 182 comprise a plurality of typically three step fitting tabs 180 formed in annular wall 152 of support 16, each of which has snap fitting tabs 180. The stop position proximate this axis and the snap fitting tab 180 are elastically deformable between the bent position separated from the axis 44. Due to the position of the annular wall 52, the snap fitting tab 180 is covered by the refill 14 when the receptacle 82 is received in the cavity 40. That is, they are not visible from the outside of the packaging device 10.

Since these snap fitting tabs 180 are distributed in the annular wall 52 to be substantially equidistant from each other, in the illustrated embodiment, the snap fitting tabs 180 are positioned substantially 120 ° from each other.

Referring to FIG. 6, each snap fitting tab 180 includes a body 183 having a distal free end 185 opposite the proximal end 184 that connects to the rest of the annular wall 52. This body 180 has a substantially flat inner surface 186 oriented towards the axis 44. Each snap fitting tab 180 also includes a tooth 187 disposed at the distal end 185 and projecting radially inwardly toward the support 16 with respect to the inner surface 186. This tooth 187 has a width of substantially 8 mm when viewed in a direction orthogonal to the axis 44 and is supported by a distance of less than 0.4 mm, preferably substantially 0.38 mm with respect to the inner surface 186. Extend inward toward 16; The teeth 187 also have a radius of curvature that is substantially 1 mm when viewed in the plane including the axis 44.

Additional cooperating members 180, 182 also include a plurality of grooves 182 formed in the outer surface 188 of the peripheral wall 89 of the receptacle 82, each groove 182 being a plane (X, Y) ) And is adapted to cooperate with each snap fitting tab 180. To this end, each groove 182 has a shape that is substantially complementary to the shape of the teeth 187 of each snap fitting tab 180.

The second threshold thus amounts to 3 to 30 Newtons, preferably 3 to 20 Newtons.

Note that this second threshold is not limited to the described embodiment, and similar values may be obtained using other cooperating members 180 and 182 than those described herein.

To measure this second threshold, the same apparatus used to measure the first threshold is used. The packaging device 10 is installed in this measuring device, the lid 18 is in an open position, the refill 14 is inserted into the support 16, and the cap so that the support 16 is fixed to the stand of the measuring device. 84 is in its released position. The arch is fixed to the upper wall 88 of the receptacle 82, for example by an adhesive strip, and the hook of the measuring device engages the arch. The actuator is configured to drive the displacement of the nacelle at a speed of 155 to 175 mm / min. Finally, the actuator is actuated and the tensile force exerted on the hook is measured using a dynamometer until the refill 14 is separated from the support 16 under the influence of the force exerted by the hook. The second threshold then consists of the maximum force measured by the dynamometer prior to detachment of the refill 14.

Returning to FIG. 5, the base element 12 and the refill 14 can also be used to ensure the correct position of the refill 14 within the base element 12, in particular the first axis of rotation and the second axis of rotation 56, 132. ) To ensure that they are correctly positioned relative to each other, and to ensure that the cooperating members 180, 182 are positioned facing each other so that the refill 14 can be reliably held within the base element 12, And full proof members 190 and 192.

These full proof members 190, 192, in the illustrated embodiment, are integral with the refill 14 and parallel to the axis 92 from the free edge 118 of the peripheral skirt 114 of the receptacle 82. Tongue 190 protruding to the opposite side of the top wall 88. The pullproof members 190, 192 also include a window 192 disposed on the upper wall 60 of the support 16, which window 192 is a first axis of rotation 56 and a second axis of rotation 132. Tongue 190 may be accommodated where) is substantially orthogonal to each other.

Initially, with the exception of the mirror 80 and the annular wall 152, the various elements that form the device 10 are acrylonitrile butadiene styrene (ABS), styrene-acrylonitrile (SAN) or polypropylene. It is molded by injecting a thermoplastic material of polymer type.

Hereinafter, a method of operating the apparatus 10 will be described. In the position where the lid 18 is opened and the cap 84 is removed, as in FIG. 1, the user can use the sponge contained in the central housing 144 to extract the cosmetic and apply the cosmetic onto the surface of the body. Can be. Application is optionally monitored using mirror 80. The bottom 156 of the rigid wall 150 is optionally used to process the product using a sponge, or to wipe off excess product prior to application. If the bottom 156 includes a housing for a second cosmetic product, both products can be used simultaneously.

When the application is complete, the user folds the cap 84 in the direction of the receptacle 82 so that the rigid wall 150 enters the compartment 90. The rigid wall 150 reaches in contact with the shoulder 100. The cap 84 is then in an intermediate position.

To facilitate passage in the closed position of the cap 84, the user folds the lid 18 downward until the inner surface of the cap contacts the plate 130. The cap 84 and the lid 18 are then in contact configuration.

From this contact configuration, the user exerts a force on the lid 18 to move the lid 18 to the closed position. For example, the user presses on the top of the lid 18. The displacement of the lid 18 causes the contact point of the plate 130 with the inner surface of the lid 18 to slide along the inner surface in the direction of the first axis of rotation 56.

The inner surface formed of the mirror 80 has a smooth texture that promotes sliding of the plate 130.

The plate 130 is folded into the top surface 88 of the receptacle 82. The rigid wall 150 supported on the shoulder 100 has a reduced distance between the rigid wall 150 and the plate 130. This reduction increases the diameter of the outer surface of the peripheral wall 152 until intimate contact with the annular wall 52 of the receptacle 82 is formed.

The lid 18 is then positioned in the closed position as described for the embodiment of FIG. 5. The notch 79 fits on the hook 78 to lock the lid 18.

Thus, the user can make intimate contact between the cap 94 and the receptacle 82 in a single operation and position the lid 18 in the closed position. Movement of the cap 84 by the lid 18 provides a lever that minimizes the force required to convert the cap 84 into a closed configuration.

In the closed position, the inner surface of the lid 18 exerts a uniform pressure on the seal formed by the wall 152 and the wall 89. In particular, this pressure uniformity is facilitated by the fact that the inner surface of the lid 18 is formed by the mirror 80.

Conversely, in order to open the device 10 from the closed position of the lid, the user presses the pusher 77 to separate the hook 78 from the notch 79. When the lid 18 is unlocked, the compressive force exerted on the annular wall 152 of the cap 84 by the peripheral wall 89 of the receptacle 82 ejects the plate 130 out of the compartment 90. . As a result, the plate 130 moves away from the bottom 86 of the receptacle 82 and slightly lifts the lid 18. However, this displacement is stopped by the holding device 170.

The user then displaces the lid 18 to its open position and then grips a sponge disposed within the central housing 144.

The user then sufficiently passes a finger between the plate 130 and the top wall of the receptacle 82 on the side end 172 on the opposite side of the hinge 132, at which point a lifting force greater than the first threshold is applied to the holding device. Overcome the resistance by 170. Next, the user is accompanied by the movement of the cap 84 to the unlocked position of the cap to release access to the cosmetic contained within the first housing 110.

The device 10 is then located in the configuration of FIG. 1 suitable for using a cosmetic article.

Thus, the device 10 can be switched from its closed transport configuration to a configuration for use without changing the handling of the device 10.

When the cosmetics contained in the first housing 110 are exhausted, the user separates the refill 14 from the base element 12 to refill the packaging device 10 with the product. To this end, the user displaces the lid 18 to an open position as described above, and then the user is oriented along the axis Z in the direction of the orifice 42 on the bottom 86 of the receptacle 82. Draw force greater than the second threshold. Accordingly, the refill 14 is pressed in the direction of the orifice 42. Since the force applied is greater than the second threshold, it is possible to overcome the resistance of the cooperating members 180, 182, so that the refill 14 is evicted out of the cavity 40.

The user then assembles a new identical refill (not shown) containing the cosmetic in the first housing 110 instead of the refill 14. To this end, the user places a new refill in the cavity 40 of the support 16, and then the user is oriented along the axis Z in the direction of the bottom 20 of the support on top of this new refill. Add. By applying a force greater than the second threshold, this force can overcome the resistance of the cooperating members 180, 182, resulting in a new refill engaging the base element 12. The shoulder 54 prevents the new refill extending beyond the engagement position with the base element 12 and being ejected through the cut 46 under the action of the pushing force applied by the user.

The replacement of the refill 14 is particularly easy thanks to the invention. In practice, it is sufficient to apply some pressure on the refill to dislodge the refill 14, and the pressure to apply on this new refill to install the new refill in place is also small.
