AI Technical Summary
Existing cosmetic product packaging devices, such as those for lipstick sticks, often suffer from mechanical deterioration when forced rotation is applied, leading to premature wear and potential malfunction due to the cup lugs exiting the helicoidal slides and grooves.
The device incorporates a means of rotation blocking between the guide and the sheath, which prevents the cup from serving as an end-of-travel stop, thereby limiting the risk of deformation and premature wear. This blocking mechanism is activated when the cup is in fully deployed, fully retracted, or intermediate positions, ensuring that the rotation is halted by the designed stops rather than the cup lugs.
This solution effectively prevents mechanical deterioration and premature wear of the packaging device, ensuring reliable operation and extending the device's lifespan by maintaining the cup's integrity during forced rotation.
Description
Technical field of the invention
[0001] The invention relates to a device (also called a mechanism) for packaging a cosmetic product, such as a cosmetic product stick, in particular a lipstick stick.
[0002] The invention relates more particularly to a device intended to be mounted on an actuation base of a cosmetic product application receptacle comprising at least a first element conventionally called a guide, a cup intended to receive the cosmetic product stick and a second element conventionally called a sheath, in which the rotation of the guide relative to the sheath causes an axial movement of the cup causing the cosmetic product to exit and / or enter. Technical background
[0003] Documents US5143464A, GB671388A, US2021 / 076803A1 are part of the state of the art.
[0004] Devices of this type are known from the state of the art, used for packaging a cosmetic product, such as a cosmetic product stick, in particular but not exclusively for a lipstick stick.
[0005] The stick is held by its base in a cup which slides axially between at least one retracted position and a position for applying the cosmetic product in which at least a portion of the cosmetic product stick extends axially out of the device.
[0006] In a known manner, such kinematics is obtained by means of a rotary mechanism comprising a guide and a sheath which, mounted concentrically, comprise for one at least one slide and for the other at least one helical groove which are respectively crossed radially by at least one lug secured to the cup carrying the stick.
[0007] The cup generally has a pair of lugs, the two lugs being arranged diametrically opposite each other, the guide then being provided with two slides and the sheath with two helical grooves.
[0008] The actuation of the mechanism is generally controlled manually by applying a rotational movement to the base of the device, which rotational movement is transmitted to the mechanism to cause the axial displacement of the cup containing the cosmetic product.
[0009] When actuating the mechanism, it is possible that the cup lugs may come out of the slides and / or helical grooves, particularly at the end of the stroke, especially in the retracted position, if the actuation is forced.
[0010] Typically, the cup is made of polyoxymethylene (POM) or acrylonitrile butadiene styrene (ABS), while the other components are made of a different material. Although there is a relative difference in hardness between the parts, the cup lugs are regularly observed to protrude from the helical grooves of the sheath and / or the guide slides.
[0011] Furthermore, this problem is also present in the use of a single-material mechanism, that is to say a mechanism whose cup, sheath and guide are made of the same material, in particular a plastic material.
[0012] Using the same material to make the mechanism is particularly interesting for recycling the cosmetic product after use. Indeed, the presence of two different materials presents disadvantages during recycling where the two parts must be separated.
[0013] The aim of the invention is in particular to propose a solution making it possible to resolve at least some of the drawbacks of the state of the art, in particular a solution which makes it possible to avoid damage to the device if a user forces the actuation, in particular if the user forces the actuation in rotation. Summary of the invention
[0014] The invention is defined by the features of claim 1.
[0015] Thus, the invention relates to a device intended to be mounted on an actuation base of a cosmetic product application receptacle, in particular a cosmetic product stick, said device being designed to cause the cosmetic product to exit by at least one rotational movement, said device comprising at least one guide, a cup intended to receive the cosmetic product and a sheath, the sheath internally comprising at least one helical groove and the guide being mounted in rotation in the sheath, the rotation of the guide relative to the sheath causing an axial movement of the cup between a fully deployed position and a fully retracted position.
[0016] According to the invention, the device comprises at least one means for locking the guide in rotation relative to the sheath when the cup is in the fully deployed position and / or the fully retracted position and / or close to being in the fully deployed position and / or the fully retracted position.
[0017] The fully retracted position corresponds to a position in which the cosmetic product is inside the device for its protection and storage and the cup is in the lower end position.
[0018] The fully deployed position corresponds to a position in which the cosmetic product is deployed axially upwards so that its free end extends out of the device through the opening and the cup is in the upper end-of-travel position.
[0019] By "close to", we mean on the verge of, at a short distance from, which is almost in the fully deployed or fully retracted position. Thus when the cup is at the end of its upper or lower travel or close to being at the end of its upper or lower travel, the locking means stops the rotation of the guide relative to the sheath. Thus, if the user forces the device to rotate, it is not the cup that serves as the end-of-travel locking means but the rotation locking means between the guide and the sheath. This thus limits any risk of damage to the device, in particular the cup, such as deformation and / or premature wear leading, for example, to the cup accidentally coming out of the device causing the device to malfunction.
[0020] According to different embodiments of the invention, which may be taken together or separately: the guide, the cup and the sheath are made of plastic, the guide, the cup and the sheath are made of identical plastic, the plastic is polypropylene, the device has an upper portion located towards an opening of the device through which the cosmetic product exits and an opposite lower portion, the rotation locking means is located at the upper portion of the device, the rotation locking means is located at the lower portion of the device, the at least one stop of the guide and the at least one stop of the sheath are of complementary shape so as to cooperate together, the cup comprises at least one lug projecting radially outwards and cooperating with at least one slide of the guide,the at least one slide and the at least one lug are configured to serve as a means of locking the cup in rotation relative to the guide when the cup is in the fully deployed position and / or the fully retracted position and / or close to being in the fully deployed position and / or the fully retracted position, the at least one lug has two parallel flats configured to cooperate with walls of the at least one helical groove of the sheath, the flats have an inclination similar to an inclination of a trajectory of the helical grooves.
[0021] The invention also relates to a receptacle for applying a cosmetic product comprising a cover, an actuation base which comprises a device as described above, the actuation base making it possible to actuate the device so as to allow the entry and / or exit of the cosmetic product.

Detailed description of the invention
[0023] By convention, the “axial” direction corresponds in the figures to that of the main axis A of the device (also called mechanism) intended to be mounted on an actuation base of a cosmetic product application receptacle, such as a cosmetic product stick, in particular a lipstick stick, and the “radial” direction is orthogonal to the axial direction. In the detailed description of the figures which follows, the terms “upper” and “lower” or “top” and “bottom” will be used in a non-limiting manner with reference to the axial direction, the upper part of the device corresponding to that through which the cosmetic product stick exits the device for its application.
[0024] Similarly, the terms "outer or external" and "inner or internal" are used in reference to the radial direction, an outer element being radially further from the A axis than an inner element.
[0025] THE figures 1 to 7 illustrate a first embodiment of a device 10 intended to be mounted on an actuation base of a cosmetic product application receptacle according to the invention.
[0026] THE figures 8 to 15 illustrate a second embodiment of a device 10 intended to be mounted on an actuation base of a cosmetic product application receptacle according to the invention.
[0027] Preferably, the cosmetic product (represented in dotted lines on the figure 2 ) is a stick 12 of cosmetic product and, more particularly, the stick 12 of cosmetic product is a lipstick stick intended to be applied by rubbing, alternatively a lip care balm.
[0028] The device 10 is designed to extrude the cosmetic product by at least one rotational movement.
[0029] The device 10 has an axis A, called the main axis.
[0030] The device 10 comprises at least a first element, conventionally and hereinafter called guide 14.
[0031] The guide 14 mainly comprises a tubular body 16 which extends axially from a base 18 forming the lower end of the guide 14 to an upper outlet opening 20 intended to be crossed by the stick 12 of cosmetic product.
[0032] The external surface of the base 18 is for example provided with grooves to facilitate its handling when using the device 10.
[0033] Preferably, the guide 14 comprises two slides, respectively a first slide 22 and a second slide 24, which are constituted by slots passing radially through the wall of the body 16 and are arranged diametrically opposite each other.
[0034] The slides 22, 24 extend axially in the body 16 of the guide 14, the first slide 22 is closed axially at its upper end while the second slide 24 is open. The slides 22, 24 are closed at their lower end located on the side of the base 18.
[0035] The slides 22, 24 each have straight and parallel edges. The first slide 22 has at one of its axial ends an upper notch 26a and at the other of its ends a lower notch 28a, said notches 26a, 28b extending circumferentially.
[0036] In both embodiments, the second slide 24 also includes upper and lower notches 26b, 28b.
[0037] In conventional systems, the notches 26a, 26b, 28a, 28b are intended to form means for blocking the end of travel of a cup 30. The device 10 comprises the cup 30 which receives the stick 12 of cosmetic product as illustrated in figure 2 .
[0038] The cup 30 is intended to be mounted to slide axially in the guide 14, between a completely retracted position and a completely deployed position.
[0039] The fully retracted position corresponds to a position in which the stick 12 is inside the device 10 for its protection and storage and the cup 30 is in the lower end-of-travel position as illustrated in figures 12 And 13 .
[0040] The fully deployed position corresponds to a position in which the stick 12 is deployed axially upwards so that its free end extends out of the device 10 through the opening 20 and the cup 30 is in the upper end-of-travel position as illustrated in figures 1 And 2 .
[0041] The cup 30 can also be in retracted intermediate positions and in deployed intermediate positions, called intermediate application positions.
[0042] The retracted intermediate positions correspond to positions in which the stick 12 is inside the device 10 for its protection and storage but without the cup 30 being at the bottom end of its travel.
[0043] The intermediate application positions correspond to positions in which the stick 12 is deployed axially upwards so that its free end extends out of the device 10 through the opening 20 and it is possible to apply the cosmetic product.
[0044] Preferably, the cup 30 comprises two lugs 32 which project radially outwards, said lugs 32 each being engaged in one of the slides 22, 24 of the guide 14 and passing through them to extend radially outwards beyond the external surface of the body 16 of the guide 14.
[0045] The cup 30 comprises a cylindrical wall which, extending axially over a given height, delimits a housing which receives the lower part of the stick 12 and a bottom.
[0046] In a variant not shown, the cup is made in two parts, respectively an upper cup intended to receive the stick of cosmetic product and a lower cup which, sometimes also called a “cup motor”, cooperates with the mechanism of the device to ensure sliding between the retracted and application positions.
[0047] In such a variant, the two parts of the cup are firmly assembled with each other, for example by interlocking.
[0048] The device 10 comprises a second element, conventionally and hereinafter called the sheath 40. As shown here, the sheath 40 has a cylindrical shape.
[0049] The sheath 40 may receive an outer jacket (not shown) inside which the sheath 40 is introduced and immobilized in rotation due to the force fitting or for example the use of glue to fix the sheath 40 and the jacket together.
[0050] In the remainder of the description, the term “sheath” must therefore be interpreted in a non-limiting manner as also designating an assembly consisting of a sheath 40 and such a jacket.
[0051] Preferably, the sheath 40 internally comprises diametrically opposed helical grooves 42, 44, with which the free ends of the lugs 32 of the cup 30 cooperate in operation. The sheath 40 comprises an internal wall 46 provided with said helical grooves 42, 44.
[0052] The sheath 40 comprises respectively an upper edge 50 located at its upper axial end and a lower edge 52 located at its lower axial end, said edges 50 and 52 being circumferentially continuous.
[0053] The sheath 40 is intended to be mounted by snap-fastening onto the guide 14 to obtain, after assembly, the devices 10 shown in particular in figures 2 , 5 And 13 .
[0054] The guide 14 is mounted in rotation in the sheath 40.
[0055] In such a device 10, the rotation of the guide 14 by means of its base 18 relative to the sheath 40 causes an axial movement of the cup 30, more precisely an upward movement or a downward movement of the cup 30 depending on the direction of rotation.
[0056] The cosmetic product stick 12 moves axially with the cup 30 between the fully extended position and the fully retracted position.
[0057] In the two embodiments shown, the guide 14, the cup 30 and the sheath 40 are advantageously made of plastic.
[0058] Preferably, the guide 14, the cup 30 and the sheath 40 are made of identical plastic material.
[0059] The plastic material may be selected from polypropylene (PP), polyethylene terephthalate (PET), recycled polyethylene terephthalate (R-PET), a thermoplastic elastomer (TPE), polyethylene (PE), such as low density polyethylene (LDPE) and / or high density polyethylene (HDPE), a composite material, a post-consumer recycled (PCR) material and / or a similar material.
[0060] These include plastic materials with a hardness between 70 shore A and 90 shore D.
[0061] Preferably, it is recycled or non-recycled polypropylene and / or polyethylene terephthalate.
[0062] Thus, advantageously, all the parts of the device 10 are made of plastic material preferably chosen from polypropylene and / or polyethylene terephthalate.
[0063] Plastic parts can be easily obtained by injection and lead to a lightweight device 10.
[0064] Furthermore, the use of plastic materials, in particular similar plastic materials for the entire device 10, makes it easier to recycle. In particular, polypropylene and polyethylene terephthalate are two plastic materials whose recycling cycle is well known.
[0065] The guide 14 comprises, axially at its upper end, a rim 54 which extends radially outwardly.
[0066] The flange 54 is circumferentially interrupted at the open upper end of the slide 24 whereby the guide 14 can deform radially to facilitate the mounting of the sheath 40 before returning to its initial shape.
[0067] According to the invention, in the two embodiments illustrated, the device 10 comprises a means for locking the guide 14 in rotation relative to the sheath 40 when the cup 30 is in the fully deployed position and / or the fully retracted position and / or close to being in the fully deployed position and / or the fully retracted position.
[0068] "Close to", about to, within a short distance of, which is almost in the fully extended or fully retracted position.
[0069] Advantageously, the rotation locking means is located at an upper portion 56 of the device 10 and / or at a lower portion 58 of the device 10.
[0070] The upper portion 56 of the device 10 is located towards an opening 60 of the device 10 intended to be crossed by the stick 12 of cosmetic product and through which the cosmetic product exits.
[0071] The lower portion 58 is the portion opposite the upper portion 56 and at the level of which the base 18 is located.
[0072] Advantageously, the rotation locking means comprises a plurality of stops configured to cooperate together.
[0073] In particular, at least one of the stops is located on the guide 14 and cooperates with at least one other of the stops located on the sheath 40. Thus, the at least one stop of the guide 14 and the at least one stop of the sheath 40 may be of complementary shape so as to cooperate together.
[0074] In the first embodiment, the rotation locking means is located at the lower portion 58 of the device 10. These are two stops, one of which is located on the guide 14 and the other is located on the sheath 40.
[0075] The stop located on the guide 14 is a radial excess thickness 62 of material projecting from an external surface 64 of the guide 14. The excess thickness 62 is arranged in a lower portion 58 of the guide 14 located axially above the base 18 of the guide 14.
[0076] The excess thickness 62 is of elongated shape and extends axially from the base 18 towards the opening 56 of the device 10.
[0077] The excess thickness 62 of material comprises a vertical side 66 and an inclined side 68. In other words, the excess thickness 62 has a generally trapezoidal shape.
[0078] The stop located on the sheath 40 is a tab 70 projecting axially from the lower edge 52 of the sheath 40. The tab 70 extends from a wide base at the lower edge of the sheath 40 to a narrow free end.
[0079] The leg 70 comprises a vertical side 72 and an inclined side 74. In other words, the leg 70 has a general trapezoidal shape.
[0080] In this first embodiment, when the cup 30 is in the completely retracted position and / or close to being in the completely retracted position, the vertical side 72 of the tab cooperates with the vertical side 66 of the radial excess thickness 62 of material as illustrated in Figures 5 and 6 .
[0081] Thus when the cup 30 is at the end of its lower stroke or reaches the end of its lower stroke, the two stops 62, 70 come into contact. The rotation of the guide 14 relative to the sheath 40 is thus stopped in the direction of descent of the cup 30, consequently blocking the rotation of the cup 30 in the direction of descent.
[0082] Thus, unlike a conventional device of the prior art, it is not the lugs 32 of the cup 30 which serve as end-of-travel locking but the stops 62, 70. This thus limits any risk of the cup 30 becoming damaged, in particular the lugs 32 coming out of the slides 22, 24 of the guide 14 and / or the helical grooves 42, 44 of the sheath 40.
[0083] The fully retracted position is the position of the cup 30 that is most stressed and the one where the risk of failure is greatest given that the cup 30 inside the device 10 is not visible. Thus advantageously, in this position it is the vertical sides 66, 72 of the stops 62, 70 which come into contact, allowing greater resistance to be absorbed.
[0084] When the cup 30 is in the fully deployed position and / or close to being in the fully deployed position, it is the inclined sides 68, 74 of the tab 70 and the radial excess thickness 62 of material which cooperate as illustrated in figures 2 And 3 . In other words, at the end of the upper stroke of the cup 30, the two inclined sides 68, 74 of the stops 62, 70 come into contact blocking the upward rotation of the guide 14 relative to the sheath 40, consequently blocking the rise of the cup 30. Here again, it is the stops 62, 70 which serve as end-of-stroke blocking and not the lugs 32 of the cup 30. This thus limits any risk of the cup 30 becoming damaged, in particular the lugs 32 coming out of the slides 22, 24 of the guide 14 and / or the helical grooves 42, 44 of the sheath 40.
[0085] In the second embodiment, the rotation locking principle is similar. Here again, it is not the lugs 32 of the cup 30 which serve as end-of-travel locking but stops located on the sheath and the guide. This thus limits any risk of the cup 30 becoming damaged, in particular the lugs 32 coming out of the slides 22, 24 of the guide 14 and / or the helical grooves 42, 44 of the sheath 40.
[0086] This second embodiment differs from the first, by the location of the stops and their shape.
[0087] In the second embodiment, the rotation locking means is located at the upper portion 56 of the device 10. These are two stops, one of which is located on the guide 14 and the other is located on the sheath 40.
[0088] The stop located on the guide 14 is a tab 76 projecting axially from the upper rim 54 of the guide 14. The tab 76 is in the extension of the upper rim 54 of the guide 14 at the level of the notch 26b and the interruption of the circumference of the rim 54.
[0089] The leg 76 extends from a wide base at the upper rim 54 of the guide 14 to a narrow free end.
[0090] The leg 76 comprises a vertical side 78 and an inclined side 80. In other words, the leg 76 has a general triangular shape.
[0091] The stop located on the sheath 40 is a radial excess thickness 82 of material projecting from the internal surface of the sheath 40. The excess thickness 82 is arranged in an upper portion 56 of the sheath 40.
[0092] The excess thickness 82 is of elongated shape and extends circumferentially at the level of the upper edge 54 of the sheath 40. The excess thickness 82 of material has a vertical side 84 and an inclined side 86. In other words, the excess thickness 82 has a generally triangular shape.
[0093] As in the first embodiment, when the cup 30 is in the fully retracted position and / or close to being in the fully retracted position, the vertical side 78 of the tab 76 cooperates with the vertical side 84 of the radial excess thickness 82 of material as illustrated in figures 13 and 14 .
[0094] When the cup 30 is in the fully deployed position and / or close to being in the fully deployed position, it is the inclined sides 80, 86 of the tab 76 and the radial excess thickness 82 of material which cooperate as illustrated in figures 9 and 10 .
[0095] In each of the embodiments, advantageously, the stops 62, 70, 76, 82 have a vertical side 66, 72, 78, 84 and an inclined side 68, 74, 80, 86, giving them a generally triangular or trapezoidal shape. This particular shape having a wide base makes it possible to reinforce the resistance of the stops 62, 70, 76, 82 to prevent them from breaking, in particular when the user forces them in rotation.
[0096] In addition, the inclined sides 68, 74, 80, 86 make it possible to limit the reduction in the rotational movement of the cup 30. Due to this particular shape, the stops 62, 70, 76, 82 do not hinder the raising and lowering of the cup 30 which can be done with the same amplitude as for a conventional device.
[0097] The stops 62, 70, 76, 82 are configured so that in the fully retracted position of the cup 30, the position most stressed by the user, it is the vertical sides 66, 72, 78, 84 which cooperate to absorb greater resistance.
[0098] Furthermore, in each of the two embodiments shown, the two lugs 32 of the cup 30 are of generally rounded shape and advantageously have two parallel flats 90 configured to cooperate with walls 92 of the helical grooves 42, 44 of the sheath 40.
[0099] Preferably, the flats 90 have an inclination similar to the inclination of the trajectory of the helical grooves 42, 44, as can be seen in FIG. figure 16 .
[0100] In other words, each lug 32 extends in a direction similar to the direction of the helical groove 42, 44 in which it is engaged.
[0101] This particular shape of the lugs 32 is adapted to the shape of the helical grooves 42, 44 so as to facilitate their sliding and so that they fit there without coming out even if a user forces the rotation. The risk of the cup 30 being damaged is thus reduced.
[0102] The device 10 is intended to be a component of a receptacle (not illustrated), also called a case, of a cosmetic product.
[0103] Generally, the receptacle comprises a cover which is associated with an actuating base having a complementary shape, the base and the cover together defining an external contour of the receptacle.
[0104] The receptacle further comprises the device 10 for dispensing the cosmetic product stick as described previously.
[0105] In a non-limiting manner, the cover, the base of the receptacle and the device 10 have a cylindrical shape with a circular section.
[0106] Preferably, the cover is removable. The cover is capable of occupying at least one open position in which the cover is separated from the base in order in particular to allow the application of the cosmetic product and a closed position in which the cover is secured to the base.
