The present invention relates to an assembly forming a cap for a cosmetic product container including two elements and release means. It applies in particular to perfume bottles or to any type of container for cosmetic products.
It is common in the prior art to provide perfume bottles with a decorative cap which can, for example, cover or enclose a device for diffusing fluid (liquid, cream) by projection (under pressure or by manual mechanical pump, for example). These caps are generally either irremovable, or the elements which constitute them are made in such a manner that they are difficult to recycle. They are therefore discarded, with the consequences that can be imagined.
There are therefore many drawbacks to making the current caps from a design, manufacturing and especially ecological and economic point of view.
The present invention aims at overcoming these drawbacks with an approach which is totally innovative, particularly compact and easy to use, allowing designing any type of cap, in numerous shapes and a multiplicity of materials.
To this end, according to a first aspect, the present invention relates to an assembly forming a cap for a cosmetic product container, said assembly having a longitudinal axis along which there extend a first element intended to be mounted on the container and a second element detachably assembled around the first element, characterized in that:
The invention is implemented according to the embodiments and variants set out below, which are to be considered individually or according to any technically effective combination.
According to a first embodiment, the additional release means is a member having magnetic properties which is adapted to be displaced under the effect of a determined external magnetic field, said element having magnetic properties being axially movable between a first rest position when it is placed outside the magnetic field and a second active position to disengage the tabs from the notches when it is placed in said magnetic field.
Preferably, the radially elastically deformable tabs respectively have peripheral end hooks adapted to penetrate into the notches of the second element, and the member having magnetic properties is a ring-shaped magnet disposed around central fingers which are secured to said tabs and having a conical outer surface, said fingers bringing together said tabs radially in the direction of the longitudinal axis when the magnet passes from the rest position to the active position, thus causing the disengagement of the hooks out from the notches.
Advantageously, the central fingers, the notches and the radially elastically deformable tabs are three in number and are evenly angularly distributed.
According to a second embodiment, the additional release means is an axially movable tool exclusively inside the first element between a first rest position and a second active position to disengage the tabs from the notches.
According to a particular embodiment of the present invention, the radially elastically deformable tabs have respectively, at the free ends thereof, peripheral hooks adapted to penetrate into the notches of the second element, the tabs being secured to a wall of the first element being reduced in the direction of said tabs, and the axially movable tool is a rod provided, at one working end, with radial pushers, the axial displacement of the tool along the inner wall of the first element causing the radial spacing of the tabs by the pushers and the disengagement of the hooks out from the notches.
Advantageously, the first element includes, along the inner wall thereof, grooves for inserting and axially guiding the pushers of the tool towards the hooks.
Preferably, the pushers, the notches and the radially elastically deformable tabs are three in number and are evenly angularly distributed.
According to a third embodiment of the present invention, the first element includes an internal thread and the additional release means is a rod provided with an external thread, said rod being axially movable and in rotation along/about the axis inside the first element between a first rest position and a second active position in which the respective threads are engaged to gradually disengage the tabs from the notches of the second element as the screwing of the rod into the first element progresses.
According to a complementary aspect, the rod is further provided with an enlarged end head intended to bear against a conical inner wall of the first element carrying the radially elastically deformable tabs, said tabs being radially spaced apart from each other exclusively under the effect of the action of the enlarged head on said inner wall as the screwing of the rod into the first element progresses.
According to a particularly interesting aspect of the present invention, the tabs are spaced apart from each other exclusively under the effect of the penetration into each other of the respective threads as the screwing of the rod into the first element progresses.
According to a preferred feature, the notches are blind housings.
According to a variant, the notches are through holes.
Other advantages, aims and features of the present invention emerge from the following description made, for explanatory and not limiting purposes, with reference to the appended drawings, in which:
According to this first mode, this assembly 1 includes an outer decorative cover 2, for example a (recyclable) aluminum cylinder of small thickness and closed by a wall 5 at an upper end 3, which is mounted (preferably with a very small clearance) on an assembly 100 including a first element/insert 110, for example made of recyclable plastic material, preferably bio-sourced, connected to a second element/insert 120, for example made of (recyclable) aluminum, and additional release means 130.
The cover 2 and the different portions 110, 120 and 130 of the assembly 100 extending along a common longitudinal axis XX′.
The first element 110 generally includes a main body 111 of essentially cylindrical shape extending along the axis XX′ provided, at an upper rim 112, with three radially elastically deformable tabs 115 each provided with a end hook 116 protruding radially away from the axis XX′. The tabs 115 are evenly distributed (that is to say at 120°) over the periphery of the first element 110 and are spaced from each other by a longitudinal slot allowing the aforementioned elastic radial deformation.
The second element 120 (see
More specifically, in the assembled position of the two elements 110 and 120 represented in
The assembly 100 of
In the present case, the magnet 131 takes the form of a ring which locally surrounds protrusions 117 belonging to the radially elastically deformable tabs 115 and axially erected away from the upper rim 112 so as to keep the latter close to the main axis of the assembly (assembled position). To this end, these three protrusions 117 each have an outer surface 118 together forming a conical profile which widens as one moves axially away from the rim 112.
Thus, when the magnet 131 is displaced axially along the arrow F, under the effect of an external magnetic field S of a suitable strength, from its rest position (hooks 116 engaged in the notches 126) moving away from the rim 112 of the first element 110, it gradually radially tightens the protrusions 117 as it travels through the conical outer shape 118 of the latter, which gradually disengages the hooks 116 from the notches 126 of the second element thanks to the radial elasticity of the tabs 115 (more specifically, the hooks 116 approach together the axis XX′). Once the hooks 116 have been completely disengaged, the two elements 110 and 120 can be completely released to be recycled individually according to their construction material, which allows an easy and total recycling of the assembly 1 as a whole.
The assembly also includes a weight element 140 intended to weigh it down (sensation of perceived quality and better adhesion) disposed between the first element 110 and the second element 120 (see
A second magnet 150, of the annular type, is also provided (
In this embodiment, the assembly 1 includes a cover 2 and an assembly 200 comprising a first internal element 210, a second external element 220, additional means 230 for releasing the two elements from each other, a weight element 240 and a magnet 250 for removable fastening, these last two portions being similar to their equivalents of the previous embodiment.
The first element 210 generally includes a main body 211 of an essentially cylindrical shape extending along the axis XX′ provided, at an upper rim 212, with three radially elastically deformable tabs 215 each provided with an end hook 216 protruding radially away from the axis XX′. The tabs 215 are evenly distributed (that is to say at 120°) over the periphery of the first element 210 and are spaced from each other by a longitudinal slot allowing the aforementioned elastic radial deformation.
The second element 220 (see
Thus, as in the first embodiment, in the assembled position of the assembly 200, the radially elastically deformable tabs 215 are in an unconstrained rest position such that the hooks 216 penetrate radially into the notches 226. The first and second elements therefore cannot be separated except by forcing them and breaking them.
The cover 2 comes, in turn, fit around the second element 220.
In accordance with
The interior of the first element 210 includes, at each of the radially elastically deformable tabs 215, three of the longitudinal grooves 214 having a conical shape narrowing slightly as approaching the hooks 116, which are intended to receive the radial protuberances 234 of the additional release means 230.
The operation of this assembly 200 is as follows.
The rod 231 of the additional release means 230 is inserted axially (manually or mechanically) inside the first element 210, and the radial protrusions 234 gradually penetrate into the internal grooves 214. The inside of the first element 210 being slightly conical at said grooves 214, the protuberances 234 gradually move apart the radially elastically deformable tabs 215 as the rod 231 advances axially (
This variant, as in the preceding examples, the assembly 1 includes a cover 2 which is intended to cover an assembly 300 comprising a first element 310 forming a plastic insert intended to be assembled with a second element 320 made of recyclable aluminum.
As previously, the first element 310 includes a shape of a longitudinal cylinder 311 extending along the axis XX′ and has, at a rim 312, radially elastically deformable tabs 315 (see
The second element 320 comprises, in turn, (see
In accordance with
The additional release means 330 includes, in turn, as illustrated in
As previously, the assembly 300 also includes a metal weight element 340 and a magnet 350.
The operation of this third embodiment is as follows.
Once the cover 2 has been removed, the user or a machine places the additional release means 330 inside the internal element 310, then he rotates said additional release means 330 so as to screw it into said internal element 310 by interpenetration of the external 334 and internal 314 threads.
During this rotation, the additional release means 330 gradually axially penetrates into the internal element 310 and the cooperation of the threads 334 and 314 cause the radially elastically deformable tabs 315 to be radially spaced apart from each other as the additional release means advances axially such that the hooks 316 are disengaged from the notches 326 of the external element 320 (see
According to a fourth embodiment illustrated by
More specifically (see
The second element 420 (see
In accordance with
Unlike the third embodiment, the thread 413 is straight and not conical.
In this variant of the preceding embodiment, the additional release means 430 also includes, in addition to a rod 431 locally provided with an external thread 434 (2-3 threads for example), an enlarged head 435 located at the level a distal end 432 and intended to cooperate with the conical inner surface 419 of the first element 410.
Thus, as the external thread 434 is screwed into the internal thread 414 of the first element 410, and the additional release means 430 progresses axially in said first element 410, the enlarged head 435 moves away the radially elastically deformable tabs 415 such that the hooks 416 are gradually disengaged from the notches 426, which ultimately allows releasing the two elements 410 and 420 from each other.
It is then possible to recover and recycle independently the first element 410 and the additional release means 430 made of plastic material, on the one hand, and the outer cover 2, the second element 420, the weight element 440 and the magnet 450, on the other hand.
The four embodiments thus described are particularly effective to easily recycle portions which, ordinarily, were thrown away because they could not be released nor sorted depending on their material.
It should be understood that the detailed description of the subject of the invention, given only by way of illustration, does not, in any way, constitute a limitation, the technical equivalents also being included within the scope of the present invention.
Thus, the number and the angular distribution of the radially elastically deformable tabs, hooks and notches can vary.
The notches may open through the wall of the second element.
