Description

MOYEN DE RETENUE MECANIQUE D'UN ETUI COSMETIQUE  MEANS FOR MECHANICAL RETENTION OF A COSMETIC CASE
La présente invention concerne des moyens de retenue mécanique d'une chemise métallique sur une enveloppe en matière synthétique, d'un étui tournant du type de ceux utilisés pour contenir des produits cosmétiques, tels qu'un bâton de rouge à lèvres ou de crèmes labiales. The present invention relates to means for mechanically retaining a metal jacket on a plastic envelope, a rotating case of the type of those used to contain cosmetic products, such as a stick of lipstick or lip creams .
Lors du transport, du stockage et d'utilisations répétées de ce type d'étui cosmétique, il y a un risque que la chemise métallique se désolidarise de l'enveloppe en matière synthétique, empêchant ainsi son utilisation. Ce phénomène est accentué lorsque le capot est directement emmanché sur la chemise métallique. Cette dernière étant sollicitée en traction à chaque utilisation lors du retrait du capot. During transport, storage and repeated use of this type of cosmetic case, there is a risk that the metal sleeve disengages from the plastic casing, thus preventing its use. This phenomenon is accentuated when the hood is directly fitted on the metal jacket. The latter being stressed in traction at each use when removing the cover.
Une chemise métallique est communément fixée par l'utilisation de colles. Le désavantage majeur de ce mode de fixation, réside en ce qu'il nécessite une opération intermédiaire préalable à l'assemblage final, dont la mise en œuvre est complexe. Ce mode requiert également une quantité de colle précise, afin notamment d'éviter toute bavure. La colle peut également présenter un défaut de tenue dans des conditions extrêmes, telles que lors de chocs mécaniques ou thermiques, lors des phases de conditionnement de la pâte de rouge à lèvres ou de crèmes labiales, ainsi que lors des phases d'expéditions des produits. A metal jacket is commonly attached by the use of glues. The major disadvantage of this method of attachment is that it requires an intermediate operation prior to the final assembly, the implementation of which is complex. This mode also requires a precise amount of glue, in particular to avoid smudging. The glue may also have a holding defect under extreme conditions, such as during mechanical or thermal shock, during the conditioning phases of the lipstick paste or lip creams, as well as during the shipping phases of the products. .
Un autre moyen communément utilisé est le serrage mécanique, de la chemise métallique en périphérie de l'enveloppe en matière synthétique. Ce moyen de fixation a un impact non négligeable sur le couple de fonctionnement du mécanisme tournant. Ce qui n'est pas acceptable sur un étui de bonne facture. Ce moyen ne permet pas non plus de garantir la tenue, car le serrage est impacté par les variations dimensionnelles de production et les conformations de la matière synthétique. Another commonly used means is the mechanical clamping of the metal jacket at the periphery of the plastic casing. This fixing means has a significant impact on the operating torque of the rotating mechanism. Which is not acceptable on a holster of good quality. This means also does not guarantee the strength, because the clamping is impacted by dimensional changes in production and conformations of the synthetic material.
La présente invention propose ainsi des moyens de retenue mécanique, permettant de pallier aux inconvénients précités. Ainsi, l'etui cosmétique tournant, destiné à recevoir un produit cosmétique, tel qu'un bâton de rouge à lèvres ou de crème labiale, selon l'invention, comprend une chemise métallique emmanchée sur une gaine en matière synthétique, tandis que la chemise métallique et la gaine en matière synthétique sont tenue mécaniquement par coopération de forme, à savoir, l'une des pièces comprend au moins un profil en saillie, tandis que l'autre comprend au moins un profil en creux, les profils en creux et en saillie étant agencés en correspondance. The present invention thus proposes mechanical retaining means, making it possible to overcome the aforementioned drawbacks. Thus, the rotating cosmetic case, intended to receive a cosmetic product, such as a stick of lipstick or lip cream, according to the invention, comprises a metal jacket fitted on a sheath made of synthetic material, while the metal jacket and the plastic sheath are held mechanically by shape cooperation, ie, one of the parts comprises at least one protruding profile, while the other comprises at least one recessed profile. , the recessed and protruding profiles being arranged in correspondence.

Selon une autre alternative, au moins un profil en saillie est agencé sur la gaine en matière synthétique, le profil en saillie étant dirigé vers l'extérieur, à savoir vers la chemise métallique (5), cette dernière comprenant au moins un profil en creux, agencé en correspondance. According to another alternative, at least one projecting profile is arranged on the plastic sheath, the protruding profile being directed towards the outside, namely towards the metal jacket (5), the latter comprising at least one hollow profile. , arranged in correspondence.
Selon une troisième alternative, combinant les deux précédentes alternatives de l'invention, les deux pièces assemblées par coopération de forme comprennent chacune à la fois au moins un profil en saillie et au moins un profil en creux. According to a third alternative, combining the two previous alternatives of the invention, the two parts assembled by shape cooperation each comprise at least one projecting profile and at least one recessed profile.
Les profils par coopération de forme sont réalisés soit préalablement à l'assemblage, soit lors de la mise en forme ou du moulage, de la chemise métallique (5) et de la gaine en matière synthétique, soit après assemblage de ces dernières. Précisons qu'un profil en saillie est avantageusement une saillie (13), un enfoncement (14) ou une fenêtre (15) et une forme (16) faisant saillie, tandis qu'un profil en creux est avantageusement une fenêtre (15), un enfoncement réalisé en force ou un moulage dans la gaine en matière synthétique. Selon un mode d'exécution, tel qu'illustré à la figure 3, au moins un profil en saillie est une saillie (13), de préférence au moins deux saillies (13) agencées de manière diamétralement opposées, et est/ sont réalisée(s) par une déformation permanente de manière non perforante dans la paroi de la chemise métallique (5). Une saillie (13) est réalisée, selon un mode de réalisation, par un procédé de picotage, résultant en au moins une déformation intérieure de la paroi de la chemise métallique (5). Ce procédé de picotage est réalisé avantageusement par l'utilisation de deux outils comportant une gravure de la géométrie de la saillie (13). The profiles by shape cooperation are made either before assembly, or during shaping or molding, the metal jacket (5) and the sheath of synthetic material, or after assembly of the latter. It should be noted that a protruding profile is advantageously a protrusion (13), a recess (14) or a window (15) and a protruding shape (16), whereas a recessed profile is advantageously a window (15), a depression made in force or a molding in the plastic sheath. According to one embodiment, as illustrated in FIG. 3, at least one protruding profile is a protrusion (13), preferably at least two protrusions (13) arranged diametrically opposite, and is / are made ( s) by non-perforating permanent deformation in the wall of the metal jacket (5). A protrusion (13) is produced, according to one embodiment, by a pilling method, resulting in at least one internal deformation of the wall of the metal jacket (5). This picotage process is carried out advantageously by the use of two tools comprising an etching of the geometry of the projection (13).
Ces saillies (13) résultantes ont la forme de la gravure correspondante, de préférence ayant un profil comprenant au moins une arête, telles que pyramidale, prismatique ou tout autre forme. These resulting protrusions (13) have the shape of the corresponding etching, preferably having a profile comprising at least one edge, such as pyramidal, prismatic or any other shape.
Selon un autre mode d'exécution, au moins un profil en saillie, au niveau de la chemise métallique (5), est réalisé par un procédé d'enfoncement, résultant en une découpe partielle de la paroi. L'enfoncement (14) résultant est par exemple sous une forme semi-cylindrique, au moins ouvert vers le haut, tel qu'illustré aux figures 4a et 4b. According to another embodiment, at least one projecting profile, at the level of the metal jacket (5), is produced by a depressing process, resulting in a partial cut of the wall. The resulting depression (14) is for example in a semi-cylindrical shape, at least open upwards, as shown in Figures 4a and 4b.
Selon le mode d'exécution précédent, un enfoncement (14) au moins ouvert vers le haut, vient créer une contre forme, à savoir un profil en creux au niveau de la paroi de la gaine en matière synthétique lors de l'assemblage en force de cette dernière avec la chemise métallique (5), mais il pourrait en être autrement, un profil en creux complémentaire à l'enfoncement (14) est réalisé préalablement à l'emmanchement de la chemise métallique (5) au de la gaine en matière synthétique. Ainsi, un enfoncement (14) au moins ouvert vers le haut, vient collaborer avec une contre forme, réalisée au préalable ou moulée, au niveau de la paroi de la gaine en matière synthétique. La contre forme et l'enfoncement (14) faisant saillie venant s'imbriquer en complémentarité, assurant un maintien mécanique de l'ensemble. According to the preceding embodiment, a recess (14) at least open upwards, comes to create a counter form, namely a recessed profile at the wall of the plastic sheath during assembly force of the latter with the metal jacket (5), but it could be otherwise, a hollow profile complementary to the depression (14) is formed prior to the fitting of the metal jacket (5) to the sheath material synthetic. Thus, a recess (14) at least open upwards, collaborates with a counter form, made beforehand or molded at the wall of the plastic sheath. The against form and the recess (14) protruding coming into complementary nesting, ensuring mechanical support of the assembly.
Selon un autre mode d'exécution, tel qu'illustré aux figures 5 et 7, au moins un profil en saillie est réalisé par poinçonnage. Un procédé de poinçonnage, produit une fenêtre (15) et avantageusement une forme (16) spécifique. Cette forme (16) spécifique faisant saillie, soit crée un profil en creux dans la gaine en matière synthétique lors de l'assemblage, soit collabore avec un profil en creux agencé dans cette dernière. According to another embodiment, as shown in Figures 5 and 7, at least one projecting profile is made by punching. A punching process produces a window (15) and advantageously a specific shape (16). This specific shape (16) protruding, either creates a recessed profile in the plastic sheath during assembly, or collaborates with a recessed profile arranged in the latter.
Selon le mode d'exécution précédent, en plus de la collaboration de forme entre la forme (16) et le profil en creux agencé dans la gaine en matière synthétique, un profil en saillie au niveau de cette dernière collabore avec la fenêtre (15) de la chemise métallique (5). Selon un mode d'exécution, tel qu'illustré à la figure 6, la gaine en matière synthétique comprend une forme complémentaire (19) faisant saillie vers l'extérieur, à savoir vers la chemise métallique (5), de préférence moulée, à la fenêtre (16) correspondant à un profil en creux. La forme complémentaire (19) faisant saillie et la fenêtre (15) viennent s'imbriquer en complémentarité, assurant un maintien mécanique de l'ensemble. According to the previous embodiment, in addition to the shape collaboration between the shape (16) and the recessed profile arranged in the plastic sheath, a projecting profile at the latter collaborates with the window (15). of the metal jacket (5). According to one embodiment, as illustrated in FIG. 6, the plastic sheath comprises a complementary shape (19) protruding outwardly, namely towards the metallic sheath (5), preferably molded, to the window (16) corresponding to a recessed profile. The complementary form (19) protruding and the window (15) come to fit together in a complementary manner, ensuring mechanical retention of the assembly.
Différents mécanismes d'étui tournant comprenant chacun une chemise métallique emmanchée sur une gaine en matière synthétique sont disponibles sur le marché. Cependant la gaine en matière synthétique a généralement une fonction différente et constitue une pièce structurellement différenciée, telle qu'une enveloppe spiralée (4), une gaine inversée (20) à glissière(s) (10) ou un guide (21). Ces différents mécanismes d'étui tournant seront explicités dans la suite de la description. Various rotating case mechanisms each comprising a metal jacket fitted on a plastic sheath are available on the market. However, the sheath made of synthetic material generally has a different function and constitutes a structurally differentiated part, such as a spiral envelope (4), an inverted sheath (20) with slide (s) (10) or a guide (21). These different mechanisms rotating case will be explained in the following description.
Selon un mode de réalisation, la gaine en matière synthétique est une enveloppe spiralée (4). Ainsi un étui tournant, tel qu'illustré à la figure 2, comprend avantageusement une couronne (1) solidaire ou faisant partit intégrante de la partie inférieure d'une gaine (2) à glissière (10), à l'intérieur duquel est monté mobile, en déplacement, un curseur (3) destiné à recevoir un produit cosmétique. La gaine (2) à glissière(s) (10) est enchâssée dans une enveloppe spiralée (4) montée en collaboration avec une chemise métallique (5) par coopération de forme. La gaine (2) à glissière(s) (10) et avantageusement la couronne (1), forment un sous-ensemble, monté mobile en libre rotation axiale par rapport à l'ensemble formé par l'enveloppe spiralée (4) et la chemise métallique (5). Ajoutons que la gaine (2) à glissière(s) (10), permet d'entraîner le curseur (3) en translation axiale, lors de la rotation axiale de l'ensemble formé par la couronne (1) et la gaine (2) à gîissière(s) (10). Cet ensemble est agencé de manière à ce que la rotation axiale de la couronne (1) entraîne le curseur (3) dans un mouvement de vrille. Ce mouvement se décompose en une rotation et une translation, toutes deux simultanées et axiales par rapport à l'ensemble formé par l'enveloppe spiralée (4) et la chemise métallique (5). According to one embodiment, the sheath of synthetic material is a spiral envelope (4). Thus a rotating case, as illustrated in Figure 2, advantageously comprises a ring (1) integral or integral part of the lower part of a sheath (2) slide (10), inside which is mounted mobile, moving, a slider (3) for receiving a cosmetic product. The sheath (2) with slide (s) (10) is encased in a spiral envelope (4) mounted in cooperation with a metal jacket (5) by shape cooperation. The sheath (2) with slide (s) (10) and advantageously the ring (1), form a subassembly, mounted to move freely in axial rotation relative to the assembly formed by the spiral envelope (4) and the metal shirt (5). Let us add that the sheath (2) with slider (s) (10) makes it possible to drive the slider (3) in axial translation during the axial rotation of the assembly formed by the ring (1) and the sheath (2). ) with a slicer (10). This assembly is arranged so that the axial rotation of the crown (1) causes the slider (3) in a twisting motion. This movement is decomposed into a rotation and a translation, both simultaneous and axial with respect to the assembly formed by the spiral envelope (4) and the metal jacket (5).
Notons que la gaine (2) à glissière(s) (10) comporte, avantageusement deux glissières (10) agencées de manière diamétralement opposée, ménagée longitudinalement dans au moins une portion de sa paroi cylindrique. Précisons que la gaine (2) à glissière(s) (10) comprend un moyen de butée supérieur (8) et un moyen de butée inférieur (9) faisant saillies vers l'extérieur. En d'autres termes, ces moyens de butée (8, 9) sont avantageusement représentés par des nervures périphériques annulaires. L'enveloppe spiralée (4) comporte dans sa paroi intérieure, au moins une rainure (6) en hélice, fermée au moins à son extrémité supérieure, de préférence deux rainures (6) hélicoïdales, diamétralement opposées, Note that the sheath (2) slider (s) (10) comprises, preferably two sliders (10) arranged diametrically opposite, formed longitudinally in at least a portion of its cylindrical wall. Note that the sheath (2) slider (s) (10) comprises an upper stop means (8) and a lower abutment means (9) projecting outwardly. In other words, these abutment means (8, 9) are advantageously represented by annular peripheral ribs. The spiral envelope (4) has in its inner wall, at least one groove (6) helically closed at least at its upper end, preferably two grooves (6) helically, diametrically opposite,
L'enveloppe spiralée (4), comprend ainsi au moins une rainure hélicoïdale (6) correspondant à une première zone, qu'on qualifiera de zone négative, et une seconde zone qu'on qualifiera de zone positive, correspondant à la zone agencée entre deux portions de rainure hélicoïdale (6). il est entendu que la zone positive a une épaisseur plus importante que celle de la zone négative. The spiral envelope (4) thus comprises at least one helical groove (6) corresponding to a first zone, which will be described as a negative zone, and a second zone which will be described as a positive zone, corresponding to the zone arranged between two portions of helical groove (6). it is understood that the positive zone has a greater thickness than that of the negative zone.
Au moins un profil est avantageusement agencé au niveau d'au moins une zone positive de l'enveloppe spiralée (4). Cette configuration permet d'éviter un défaut de fonctionnement du mécanisme de rotation du curseurAt least one profile is advantageously arranged at at least one positive zone of the spiral envelope (4). This configuration makes it possible to avoid a malfunction of the cursor rotation mechanism

La chemise métallique (5) comprend avantageusement, en partie supérieure, un rebord (11), faisant saillie vers l'intérieur. The metal jacket (5) advantageously comprises, in the upper part, a flange (11), projecting inwards.
Le curseur (3) comprend en outre au moins un ergot (7) traversant au moins une glissière (10) de la gaine (2) et coopérant avec au moins une rainure (6) de l'enveloppe spiralée (4). Au moins un ergot (7) coopère ainsi en coulissement avec au moins une glissière (10) et se prolongeant dans une rainure hélicoïdale (6), permettant d'entraîner le curseur (3) en translation axiale par rapport à la couronne (1), lors de la rotation de l'ensemble formé par l'enveloppe spiralée (4) et la chemise métallique (5). La partie haute de la couronne (1) vient s'insérer avantageusement entre la partie extérieure de la gaine (2) et la partie intérieure de l'enveloppe spiralée (4), en dessous des moyens de butée inférieurs (9) de la gaine (2). The slider (3) further comprises at least one lug (7) traversing at least one slide (10) of the sheath (2) and cooperating with at least one groove (6) of the spiral envelope (4). At least one lug (7) thus slidably cooperates with at least one slide (10) and extends in a helical groove (6), for driving the slider (3) in axial translation relative to the ring (1) during the rotation of the assembly formed by the spiral envelope (4) and the metal jacket (5). The upper part of the crown (1) is advantageously inserted between the outer part of the sheath (2) and the inner part of the spiral envelope (4), below the lower abutment means (9) of the sheath. (2).
Selon un autre mode de réalisation, la gaine en matière synthétique est une gaine inversée (20) à glissière(s) (10). Ainsi, un étui tournant, tel qu'illustré à la figure 8, comprend une chemise métallique (5) emmanchée avantageusement à la partie supérieure d'une gaine inversée (20) à glissière (10), à l'intérieur de laquelle est montée mobile en translation, un curseur (3) destiné à recevoir un produit cosmétique, tandis qu'une enveloppe spiralée (4) est emmanchée sur la partie inférieure de la gaine inversée (20) à glissière (10). Plus précisément, la chemise métallique (5) est enchâsser dans un berceau localisé en partie supérieure de la gaine inversée (20) à glissière (10). According to another embodiment, the sheath of synthetic material is an inverted sheath (20) slider (s) (10). Thus, a rotating case, as illustrated in Figure 8, comprises a metal sleeve (5) advantageously fitted to the upper part of an inverted sheath (20) slider (10), inside which is mounted movable in translation, a slider (3) for receiving a cosmetic product, while a spiral envelope (4) is fitted on the lower part of the inverted sheath (20) slider (10). More specifically, the metal jacket (5) is encased in a cradle located in the upper part of the inverted sheath (20) slider (10).
La gaine inversée (20) à glissière(s) (10) comprend en outre un moyen de butée supérieur (8) et un moyen de butée inférieur (9) faisant saillies vers l'extérieur, tandis que l'enveloppe spiralée (4) est retenue par ces derniers. The inverted sheath (20) with slider (s) (10) further comprises an upper stop means (8) and a lower stop means (9) projecting outwards while the spiral wrapper (4) is retained by them.
Selon le mode de réalisation précédent, la gaine inversée (20) à glissière(s) (10), permet d'entraîner le curseur (3) en translation axiale, lors de la rotation axiale de l'enveloppe spiralée (4). According to the previous embodiment, the inverted sheath (20) slider (s) (10) allows to drive the slider (3) in axial translation, during the axial rotation of the spiral envelope (4).
Selon un autre mode de réalisation, la gaine en matière synthétique est un guide (21). Ainsi un étui tournant, tel qu'illustré à la figure 9, comprend une chemise métallique (5) emmanchée sur un guide (21). Ce dernier est emmanché sur la partie supérieure d'une pièce communément appelée noix (22) (ou nut en langue anglaise). Une partie inférieure d'un curseur (3), destiné à recevoir un produit cosmétique, à savoir une tige, est enchâssée dans une partie intérieure filetée de la noix (22). Le curseur (3) est entraîné en translation axiale à l'intérieur du guide (21) par la rotation de la noix (22). According to another embodiment, the sheath of synthetic material is a guide (21). Thus a rotating case, as shown in Figure 9, comprises a metal jacket (5) fitted on a guide (21). The latter is fitted on the upper part of a piece commonly called nut (22) (or nut in English). A lower portion of a slider (3) for receiving a cosmetic product, namely a rod, is embedded in a threaded inner portion of the nut (22). The slider (3) is driven in axial translation inside the guide (21) by the rotation of the nut (22).
