Abstract

A stick packaging and dispensing device has an elastic insert (25) for relieving pressure produced within the dispenser sleeve (2) when fitting a closure (27, 28). A device (1) for packaging and dispensing a stick (12) in a cup (11) which is located above a seal (14) and which can be axially displaced between storage and application positions within a sleeve (2) which has an outlet opening (30) closed by a removable closure (27, 28). An elastic insert (25) is provided below the seal (14) so that excess pressure within the sleeve (2), especially occurring when fitting the closure (27, 28) onto the outlet opening (30), causes axial displacement of the cup (11) away from the outlet opening and thus relieves the excess pressure.

Description

La présente invention a trait à un dispositif pour le conditionnement et la distribution d'un stick ou raisin de produit tel qu'un rouge à lèvres, un fond de teint, une composition traitante ou hydratante. L'invention est particulièrement adaptée pour les produits contenant des solvants fortement volatiles (silicones), tels qu'utilisés notamment dans certains rouges à lèvres.The present invention relates to a device for packaging and distribution of a stick or product grape such as a lipstick, a complexion, a treatment or moisturizing composition. The invention is particularly suitable for products containing highly volatile solvents (silicones), as used in particular in certain lipsticks.

Typiquement, de tels sticks sont conditionnés dans des dispositifs du type comprenant une cupule dans laquelle est montée le stick, et pouvant, en réponse à une commande d'actionnement, se déplacer axialement à l'intérieur d'une chemise entre une position de stockage et une position d'application, des moyens assurant une étanchéité sous la cupule, ladite chemise comportant un bord libre délimitant un orifice de sortie, obturé de manière étanche par un élément de fermeture amovible. Le mécanisme d'entraínement de la cupule dans son déplacement axial peut être divers. Il peut s'agir d'une tige filetée disposée sous la cupule, coopérant avec un organe formant écrou, un tel mécanisme étant commandé par un organe de manoeuvre formé d'une molette disposée sous la chemise. Alternativement, il peut s'agir d'une rampe hélicoïdale réalisée dans une paroi de la chemise, et dans laquelle se déplace un ergot porté par la cupule. De tels mécanismes sont bien connus pour ce type de conditionnement.Typically, such sticks are packaged in devices of the type comprising a cup in which the stick is mounted, and which can, in response to an actuation command, move axially inside a jacket between a storage position and an application position, means ensuring a seal under the cup, said jacket comprising a free edge delimiting an outlet orifice, closed in leaktight manner by a removable closure element. The cup drive mechanism in its axial displacement can be various. It can be a threaded rod arranged under the cup, cooperating with a nut-forming member, such mechanism being controlled by an operating member formed by a wheel arranged under the shirt. Alternatively, it can be a ramp helical formed in a wall of the shirt, and in which moves a lug carried by the cup. Such mechanisms are well known for this type of packaging.

Un des problèmes qui se pose, tient à la surpression pouvant intervenir à l'intérieur de la chemise, notamment lors de la fermeture du dispositif, ou lors d'une élévation de température à l'intérieur de la chemise. L'expérience montre qu'une telle surpression peut entraíner un déplacement de l'élément de fermeture, lequel déplacement peut provoquer une rupture d'étanchéité à la fermeture, ce qui entraíne inévitablement une évaporation des solvants contenus dans la composition formant le raisin, pouvant aller jusqu'à le rendre très rapidement totalement inutilisable.One of the problems which arises is due to the overpressure which can occur at inside the shirt, especially when closing the device, or when a rise in temperature inside the shirt. Experience shows that such an overpressure can cause a displacement of the element of closure, which displacement can cause a leak in the closure, which inevitably leads to evaporation of the solvents contained in the composition forming the grape, up to making it very quickly completely unusable.

Aussi, est-ce un des objets de l'invention que de réaliser un dispositif de conditionnement étanche et de distribution d'un produit sous forme d'un raisin, qui soit à la fois simple, économique, et fiable en termes d'étanchéité.Also, is it an object of the invention to provide a device for sealed packaging and distribution of a product in the form of a grape, which is simple, economical and reliable in terms of sealing.

D'autres objets apparaítront de manière détaillée dans la description qui suit.Other objects will appear in detail in the description which follows.

Selon l'invention, ces objets sont atteints en réalisant un dispositif pour le conditionnement et la distribution d'un produit sous forme d'un raisin disposé dans une cupule, pouvant, en réponse à une commande d'actionnement, se déplacer axialement à l'intérieur d'une chemise entre une position de stockage et une position d'application, un organe assurant une étanchéité sous la cupule, ladite chemise comportant un bord libre délimitant un orifice de sortie, obturé de manière étanche par un élément de fermeture amovible, caractérisé en ce que des moyens élastiques sont prévus sous ledit organe d'étanchéité pour, en cas de surpression à l'intérieur de la chemise, notamment lors du montage de l'élément de fermeture sur l'orifice de sortie, provoquer un déplacement axial de la cupule, dans la direction opposée audit orifice de sortie, et absorber ainsi au moins en partie ladite surpression.According to the invention, these objects are achieved by producing a device for packaging and distribution of a product in the form of a grape placed in a cup, which can, in response to an actuation command, be move axially inside a liner between a storage position and an application position, a member ensuring a seal under the cup, said shirt having a free edge delimiting an outlet orifice, sealed by a removable closure element, characterized in that elastic means are provided under said sealing member for, in case of overpressure inside the shirt, especially during mounting the closing element on the outlet orifice, causing a axial displacement of the cup, in the direction opposite to said orifice outlet, and thus at least partially absorb said overpressure.

Ainsi, la présence des moyens élastiques, dont l'élasticité ou la compressibilité est choisie de manière à autoriser le recul ou déplacement axial de la cupule en réponse à ladite surpression, permet d'absorber cette dernière, diminuant ainsi de manière sensible la contrainte exercée sur l'élément de fermeture. Ce dernier peut alors remplir pleinement son rôle, à savoir assurer une bonne étanchéité entre l'orifice de sortie et l'extérieur du dispositif, même en cas de surpression à l'intérieur de la chemise. L'étanchéité sous la cupule sépare de manière étanche le raisin de produit de toute la partie située sous la cupule, et qui contient globalement tout le mécanisme nécessaire à l'entraínement du raisin dans la position d'application. L'étanchéité peut être réalisée au niveau de la cupule, notamment par une lèvre d'étanchéité formée par le bord libre de la cupule, ou sous la cupule, par un joint torique, ou équivalent disposé sous la cupule. Le raisin de produit est ainsi isolé de l'extérieur, à la fois par le dessus et par le dessous.Thus, the presence of elastic means, including elasticity or compressibility is chosen so as to allow the cup to move back or move axially in response to said overpressure, absorbs the latter, decreasing thus significantly the stress exerted on the closure element. This the latter can then fully fulfill its role, namely ensuring good sealing between the outlet and the outside of the device, even in the event of overpressure inside the shirt. The seal under the cup separates from tightly the product grape from all the part located under the cup, and which generally contains all the mechanism necessary for training the grape in the application position. Sealing can be achieved at of the cup, in particular by a sealing lip formed by the free edge of the cup, or under the cup, by an O-ring, or equivalent placed under the cup. The product grapes are thus isolated from the outside, both from above and from below.

Avantageusement, lesdits moyens élastiques sont constitués d'un bloc de mousse ou d'un élément en matériau élastomérique. De tels moyens élastiques peuvent être formés notamment d'une mousse de chlorure de polyvinyle, de polyuréthanne, de polyéther, de caoutchouc synthétique (SBR par exemple) ou de caoutchouc naturel (NBR par exemple). Alternativement on utilise des matériaux élastomériques, suffisamment souples. A titre d'exemple, on peut citer un matériau commercialisé sous la dénomination commerciale Polynorbordene®.Advantageously, said elastic means consist of a block of foam or an element of elastomeric material. Such elastic means can be formed in particular of a polyvinyl chloride foam, polyurethane, polyether, synthetic rubber (SBR for example) or natural rubber (NBR for example). Alternatively we use elastomeric materials, sufficiently flexible. For example, we can cite a material marketed under the trade name Polynorbordene®.

L'étanchéité sous la cupule peut être assurée au moyen d'un joint torique.Sealing under the cup can be ensured by means of an O-ring.

La fermeture étanche dudit orifice de sortie peut être assurée au moyen d'un opercule thermoplastique monté à l'intérieur d'un capuchon amovible.The sealed closure of said outlet orifice can be ensured by means of a thermoplastic cover mounted inside a removable cap.

Lesdits moyens élastiques peuvent être constitués d'un ressort, et notamment d'un ressort sous forme hélicoïdale.Said elastic means may consist of a spring, and in particular of a spring in helical form.

De préférence, le déplacement axial de la cupule entre la position de stockage et la position d'application est provoqué par la mise en rotation relative d'une tige filetée disposée sous la cupule, et d'un organe formant écrou. Alternativement, l'entraínement est réalisé au moyen d'un mécanisme du type à rampe hélicoïdale tel que discuté précédemment.Preferably, the axial displacement of the cup between the storage position and the application position is caused by the relative rotation of a threaded rod arranged under the cup, and of a member forming a nut. Alternatively, the training is carried out by means of a mechanism of the type helical ramp as previously discussed.

L'organe formant écrou est avantageusement couplé en rotation avec un organe de manoeuvre monté libre en rotation par rapport à la chemise, la tige filetée étant couplée en rotation avec la chemise. Le couplage de la tige peut être réalisé en utilisant une tige filetée de section non-circulaire (par exemple du type à deux méplats sur au moins une partie de sa longueur), un organe de guidage, de section correspondante et immobile en rotation assurant le couplage en rotation de la tige filetée avec la chemise. Alternativement, un joint torique disposé sous la cupule pour assurer l'étanchéité à cet endroit, peut permettre également, par friction, le couplage en rotation de la tige filetée et de la chemise dans laquelle est montée la cupule.The nut member is advantageously coupled in rotation with a operating member mounted to rotate freely relative to the jacket, the rod threaded being coupled in rotation with the liner. Rod coupling can be made using a threaded rod of non-circular section (for example of the type with two flats over at least part of its length), a guide, of corresponding section and stationary in rotation ensuring the rotation coupling of the threaded rod with the jacket. Alternatively, a joint toric placed under the cup to seal at this point, can also allow, by friction, the rotational coupling of the threaded rod and the shirt in which the cup is mounted.

Selon une autre alternative, l'organe formant écrou est monté flottant axialement sur lesdits moyens élastiques, lesdits moyens élastiques comprenant une première extrémité en butée axiale sur ledit organe formant écrou, et une seconde extrémité en butée axiale contre une portion fixe axialement de l'organe de manoeuvre. A titre d'exemple, il peut s'agir du fond de l'organe de manoeuvre, ou d'une butée formée par une pièce montée fixement dans l'organe de manoeuvre. Dans cette configuration, le ressort et l'organe formant écrou peuvent être obtenus d'une seule pièce, formée par moulage d'un matériau thermoplastique.According to another alternative, the nut member is mounted floating axially on said elastic means, said elastic means comprising a first end in axial abutment on said member forming nut, and a second end in axial abutment against a fixed portion axially of the operating member. For example, it can be the background of the operating member, or of a stop formed by a mounted part fixedly in the operating member. In this configuration, the spring and the nut member can be obtained in one piece, formed by molding of a thermoplastic material.

De préférence, un évent est prévu au voisinage du fond de la cupule de manière à permettre de chasser l'air hors de la cupule lors du montage du raisin dans la cupule. De préférence encore, un évent est également prévu sous l'organe assurant l'étanchéité sous la cupule.Preferably, a vent is provided in the vicinity of the bottom of the cup. so as to allow the air to be expelled from the cup during assembly of the grape in the cup. More preferably, a vent is also provided under the organ ensuring sealing under the cup.

Un tel dispositif peut être avantageusement utilisé pour le conditionnement et la distribution d'un raisin de rouge à lèvres, de fond de teint, ou d'une composition traitante ou hydratante.Such a device can advantageously be used for packaging and distribution of a lipstick, foundation, or composition grape treating or moisturizing.

The cover 28, present on its internal surface, in the vicinity of its open end, a bead 29 capable of ensuring a tight closure of the outlet orifice 30, delimited by a free edge of the jacket 2, located at opposite end 3.

L'organe de manoeuvre 4 est constitué d'un élément cylindrique dont la paroi latérale présente des stries 5 aptes à faciliter la préhension et la mise en entraínement de l'organe de manoeuvre 4. Une extrémité de l'élément cylindrique formant l'organe de manoeuvre est fermée. L'autre extrémité est ouverte et se prolonge par une jupe 6 de diamètre extérieur, inférieur au diamètre intérieur de la chemise 2, de manière à pouvoir être insérée librement à l'intérieur de la chemise 2. La jupe 6 se termine par une portion formant écrou 7, apte à coopérer avec le filet d'une tige 8 dont on reparlera plus en détail par la suite. L'organe de manoeuvre 4 est monté en rotation, notamment par claquage, sur l'extrémité inférieure 3 de la chemise 2. A cet effet, un bourrelet annulaire 9 est prévu sur une surface interne de l'organe de manoeuvre 4, de manière à coopérer avec une gorge annulaire 10 prévue sur une surface extérieure de la chemise 2, au voisinage de l'extrémité 3. Lorsqu'il est monté ainsi, libre en rotation, la surface extérieure de l'organe de manoeuvre 4 est sensiblement en alignement avec la surface extérieure de la chemise 2. La jupe 6 est de hauteur telle, qu'elle s'étend sur environ 1/3 de la hauteur axiale de la chemise 2.The operating member 4 consists of a cylindrical element whose wall side has grooves 5 able to facilitate gripping and setting drive of the operating member 4. One end of the element cylindrical forming the operating member is closed. The other end is open and is extended by a skirt 6 of outside diameter, less than inner diameter of the jacket 2, so that it can be inserted freely inside the shirt 2. The skirt 6 ends with a portion forming a nut 7, able to cooperate with the thread of a rod 8 which will be discussed in more detail by the following. The operating member 4 is mounted in rotation, in particular by snap, on the lower end 3 of the shirt 2. For this purpose, a bead annular 9 is provided on an internal surface of the operating member 4, so as to cooperate with an annular groove 10 provided on a surface outside of the jacket 2, in the vicinity of the end 3. When it is mounted thus, free to rotate, the outer surface of the operating member 4 is substantially in alignment with the outer surface of the jacket 2. The skirt 6 is of such height that it extends over approximately 1/3 of the axial height of the shirt 2.

A l'intérieur de la chemise 2, est disposée une cupule 11 dans laquelle est monté un raisin de rouge à lèvres 12. La cupule comprend au voisinage de son fond un orifice formant évent 13, de manière à chasser l'air emprisonné entre le bâton de rouge à lèvres 12 et la cupule 11, lors du montage du raisin 12 à l'intérieur de la cupule 11. Le bord libre 15 de la cupule 11 forme une lèvre d'étanchéité 14, s'évasant vers l'extérieur, et apte à former étanchéité entre la cupule 11 et la surface intérieure de la chemise 2. La lèvre d'étanchéité 14, en raison de l'appui qu'elle génère sur la surface interne de la chemise 2, assure en outre une immobilisation en rotation de la cupule à l'intérieur de la chemise. Le fond 24 de la cupule 11 est relié, du côté opposé au raisin 12 à une patte 16, dont une extrémité d'accrochage 17 est apte à venir en engagement d'accrochage à l'intérieur d'un logement 18 ménagé dans une extrémité 19 de la tige filetée 8. Le montage de l'extrémité d'accrochage 17 à l'intérieur du logement 18 se fait par déformation élastique de deux ou plusieurs portions 20, 21 formant ladite patte 16. Le profil de l'extrémité d'accrochage 17 est choisi de manière à ce que ladite extrémité 17 puisse coulisser à l'intérieur du logement 18, tout en étant immobile en rotation.Inside the jacket 2, a cup 11 is arranged in which is mounted a lipstick grape 12. The cup includes in the vicinity of its melts an orifice forming a vent 13, so as to expel the air trapped between the stick of lipstick 12 and cup 11, when mounting the grape 12 to the interior of the cup 11. The free edge 15 of the cup 11 forms a lip sealing 14, flaring outwards, and capable of forming a seal between the cup 11 and the inner surface of the jacket 2. The sealing lip 14, in because of the support it generates on the internal surface of the jacket 2, ensures further immobilization in rotation of the cup inside the liner. The bottom 24 of the cup 11 is connected, on the side opposite the grape 12 to a leg 16, one hooking end of which 17 is capable of coming into engagement hooking inside a housing 18 formed in one end 19 of the threaded rod 8. The mounting of the hooking end 17 inside the housing 18 is made by elastic deformation of two or more portions 20, 21 forming said tab 16. The profile of the attachment end 17 is chosen to so that said end 17 can slide inside the housing 18, while being stationary in rotation.

Alternativement, il est possible de prévoir que le couplage en rotation de la tige filetée 8 avec la chemise 2 soit réalisé en faisant coulisser une nervure formée par le plateau transversal 23 à l'intérieur d'une rainure longitudinale réalisée dans la surface interne de la chemise 2. Cette configuration permet de se dispenser du couplage en rotation de la tige filetée et de la cupule.Alternatively, it is possible to provide for the rotational coupling of the rod threaded 8 with the sleeve 2 is made by sliding a formed rib by the transverse plate 23 inside a longitudinal groove made in the inner surface of the jacket 2. This configuration allows you to dispense with the rotational coupling of the threaded rod and the cup.

L'extrémité 22 de la tige filetée, opposée au logement 18 se prolonge jusqu'au voisinage du fond de l'organe de manoeuvre 4. Le logement 18 formé par la tige filetée 8 débouche sur un plateau transversal 23 pouvant coulisser à l'intérieur de la chemise 2. Entre le fond 24 de la cupule 11 et le plateau transversal 23, est disposé un bloc de mousse 25, notamment en polyuréthanne, sous forme d'un anneau dont le trou central est traversé par la patte 16. Le bloc de mousse 25 est de diamètre extérieur, légèrement inférieur au diamètre intérieur de la chemise 2, de manière à laisser un jeu entre le bloc de mousse 25 et la surface intérieure de la chemise. L'élasticité du bloc de mousse 25 est telle, que la résistance qu'il offre à la compression soit inférieure à la force d'accrochage du capot 27 sur la chemise 2, de manière à absorber au moins en partie la surpression à l'intérieur de la chemise. Le bloc de mousse 25 peut être remplacé par un ressort hélicoïdal.The end 22 of the threaded rod, opposite the housing 18 extends up to vicinity of the bottom of the operating member 4. The housing 18 formed by the threaded rod 8 opens onto a transverse plate 23 which can slide at the inside of the shirt 2. Between the bottom 24 of the cup 11 and the tray transverse 23, is arranged a block of foam 25, in particular in polyurethane, in the form of a ring whose central hole is crossed by the tab 16. The foam block 25 has an outside diameter, slightly smaller the inside diameter of the jacket 2, so as to leave a clearance between the block foam 25 and the inner surface of the liner. The elasticity of the block foam 25 is such that the resistance it offers to compression is lower to the attachment force of the cover 27 on the jacket 2, so as to absorb at least partly the overpressure inside the shirt. The foam block 25 can be replaced by a coil spring.

Pour utiliser ce dispositif, l'utilisatrice enlève le capot 27. Elle entraíne l'organe de manoeuvre 4 en rotation par rapport à la chemise 2, ce qui provoque un entraínement de la tige filetée 8 par rapport à l'écrou 7, et la montée axiale de la cupule 11, jusqu'à ce que la surface libre 31 du raisin 12 émerge hors de la chemise 2, au travers de l'orifice de sortie 30. Après application, l'utilisatrice entraíne l'organe de manoeuvre 4 dans la direction opposée, de manière à faire descendre le raisin 12 à l'intérieur de la chemise 2. Elle referme ensuite le capot. En raison de l'étanchéité formée à la fois sous la cupule (c.a.d. par la lèvre 14) et au dessus de la cupule (bourrelet 29 de l'opercule 28), il se produit une compression du volume d'air emprisonné dans cette partie de la chemise 2 délimitée par les deux zones d'étanchéité. Cette compression génère une surpression à l'intérieur de la chemise, laquelle surpression provoque une compression axiale du bloc de mousse 25 (comme représentée à la figure 1B), et un léger recul de la cupule 11 à l'intérieur de la chemise 2, réduisant ainsi la pression dans la partie haute de la chemise 2. La hauteur axiale du logement 18 formé par la tige filetée 8 est suffisante pour permettre un déplacement axial correspondant de l'extrémité d'accrochage 17, sur une distance environ égale à la compression du bloc de mousse 25. Cette compression peut être de l'ordre de quelques mm. L'air comprimé sous le bloc de mousse 25 en réponse à cette compression est chassée via la zone d'accrochage non étanche entre l'organe de manoeuvre 4 et la chemise 2. Alternativement, un évent spécifique est prévu dans le fond de l'organe de manoeuvre 4. Ainsi, la quasi-totalité de la surpression est absorbée par le bloc de mousse, ce qui réduit de manière sensible la contrainte axiale qui serait autrement subie par l'opercule 29 et le capot 27. Il n'y a ainsi aucun risque de désengagement du capot par rapport à la chemise 2. La fermeture étanche est donc conservée. Une telle surpression peut également se produire en cas d'élévation de la température à l'intérieur de la chemise. Le mécanisme d'absorption de la surpression est le même que celui décrit précédemment.To use this device, the user removes the cover 27. She drives the organ maneuver 4 in rotation relative to the jacket 2, which causes a drive of the threaded rod 8 relative to the nut 7, and the axial rise of the cup 11, until the free surface 31 of the grape 12 emerges from the jacket 2, through the outlet orifice 30. After application, the user drives the operating member 4 in the opposite direction, so as to make lower the grape 12 inside the shirt 2. It then closes the hood. Due to the seal formed both under the cup (i.e. by the lip 14) and above the cup (bead 29 of the cover 28), it occurs compression of the volume of air trapped in this part of the jacket 2 delimited by the two sealing zones. This compression generates a overpressure inside the shirt, which overpressure causes axial compression of the foam block 25 (as shown in FIG. 1B), and a slight recoil of the cup 11 inside the jacket 2, thereby reducing the pressure in the upper part of the jacket 2. The axial height of the housing 18 formed by the threaded rod 8 is sufficient to allow axial movement corresponding to the hooking end 17, over a distance approximately equal to compression of the foam block 25. This compression can be of the order a few mm. The compressed air under the foam block 25 in response to this compression is expelled via the non-tight attachment zone between the member maneuver 4 and the jacket 2. Alternatively, a specific vent is provided in the bottom of the actuator 4. Thus, almost all of the overpressure is absorbed by the foam block, thereby reducing sensitive to the axial stress that would otherwise be experienced by the cover 29 and the cover 27. There is thus no risk of the cover disengaging from the shirt 2. The waterproof closure is therefore retained. Such overpressure can also occur if the temperature inside shirt. The mechanism for absorbing overpressure is the same as the one described above.

Le bloc de mousse peut être de hauteur axiale de l'ordre de 1 cm. Il est clair que plus le bloc de mousse est de hauteur importante, et plus l'amortissement qu'il entraíne sera progressif.The foam block can have an axial height of the order of 1 cm. It's clear that the higher the block of foam, the more the damping that he trains will be progressive.

Les figures 2A et 2B auxquelles il est maintenant fait référence illustrent un second mode de réalisation du dispositif selon l'invention. Ce mode de réalisation diffère principalement du précédent en ce que :

  • Le moyen élastique, destiné à absorber la surpression à l'intérieur de la chemise 2 est constitué d'un ressort hélicoïdal 40 dont une extrémité 41 est en butée contre le fond 47 de l'organe de manoeuvre 4, et dont l'autre extrémité 42 porte l'organe formant écrou 7. Le ressort peut être en métal ou en matériau thermoplastique. L'élasticité du ressort 40 est telle, que la résistance qu'il offre à la compression soit inférieure à la force d'accrochage du capot 27 sur la chemise 2, de manière à absorber au moins en partie la surpression à l'intérieur de la chemise. L'organe formant écrou 7, est ainsi monté de manière flottante sur le ressort 40. L'écrou 7 est couplé en rotation avec l'organe de manoeuvre 4 au moyen d'une rainure longitudinale 45 ménagée sur la surface intérieure de l'organe de manoeuvre 4, et dans laquelle coulisse une portion 46 dudit écrou 7. Le fond 47 de l'organe de manoeuvre peut être un fond rapporté pour en faciliter le démoulage, ainsi que pour faciliter le montage du dispositif.
  • La hauteur axiale de l'organe de manoeuvre est supérieure à la hauteur de l'organe de manoeuvre du mode de réalisation précédent, de manière à pouvoir y loger le ressort 40. Le bourrelet d'accrochage 26 du capot 27 est porté par l'extrémité supérieure de l'organe de manoeuvre 4.
  • Un évent 43 est ménagé dans le fond 47 de l'organe de manoeuvre 4 de manière à chasser l'air, comprimé en réponse à la réduction de volume résultant de la compression du ressort 40.
  • L'étanchéité sous la cupule est assurée au moyen d'un joint torique 44 monté sur la périphérie du plateau transversal 23 formé par l'extrémité 19 de la tige filetée 8. Un tel joint peut être réalisé avantageusement en matériau élastomérique.
  • Le fond 24 de la cupule 11 est directement en contact avec le plateau transversal 23 avec lequel la cupule 11 est couplée à la fois en rotation et en translation. La cupule 11 est couplée en rotation avec la chemise 2 au moyen d'un ergot 101 prévu sur la surface extérieure de la cupule 11, et apte à coulisser dans une rainure longitudinale 102 ménagée dans la surface intérieure de la chemise 2. Alternativement, la tige filetée 8, peut être couplée en rotation avec la chemise 2, par le seul frottement réalisé par le joint torique 44 contre la surface intérieure de la chemise 2. Alternativement encore, la cupule 11 peut former une seule pièce avec la tige filetée 8.
  • La cupule 11 comporte une pluralité de pattes 100, espacées régulièrement, et faisant saillie à l'intérieur de la cupule 11, de manière à permettre l'accrochage du produit à l'intérieur de la cupule 11. Ces pattes 100 sont obtenues de moulage avec la cupule 11. Une telle caractéristique est particulièrement avantageuse lorsque le produit est coulé directement dans la cupule.
Figures 2A and 2B to which reference is now made illustrate a second embodiment of the device according to the invention. This embodiment differs mainly from the previous one in that:
  • The elastic means, intended to absorb the overpressure inside the jacket 2 consists of a helical spring 40, one end 41 of which abuts against the bottom 47 of the operating member 4, and the other end of which 42 carries the nut-forming member 7. The spring can be made of metal or of thermoplastic material. The elasticity of the spring 40 is such that the resistance it offers to compression is less than the attachment force of the cover 27 on the jacket 2, so as to at least partially absorb the overpressure inside shirt. The member forming a nut 7 is thus mounted in a floating manner on the spring 40. The nut 7 is coupled in rotation with the operating member 4 by means of a longitudinal groove 45 formed on the internal surface of the member maneuver 4, and in which slides a portion 46 of said nut 7. The bottom 47 of the operating member may be an added bottom to facilitate demolding, as well as to facilitate mounting of the device.
  • The axial height of the operating member is greater than the height of the operating member of the previous embodiment, so as to be able to accommodate the spring 40 therein. The attachment bead 26 of the cover 27 is carried by the upper end of the operating member 4.
  • A vent 43 is formed in the bottom 47 of the operating member 4 so as to expel the air, compressed in response to the reduction in volume resulting from the compression of the spring 40.
  • The seal under the cup is ensured by means of an O-ring 44 mounted on the periphery of the transverse plate 23 formed by the end 19 of the threaded rod 8. Such a seal can advantageously be made of elastomeric material.
  • The bottom 24 of the cup 11 is directly in contact with the transverse plate 23 with which the cup 11 is coupled both in rotation and in translation. The cup 11 is coupled in rotation with the jacket 2 by means of a lug 101 provided on the outside surface of the cup 11, and capable of sliding in a longitudinal groove 102 formed in the inside surface of the jacket 2. Alternatively, the threaded rod 8, can be coupled in rotation with the jacket 2, by the only friction produced by the O-ring 44 against the interior surface of the jacket 2. Alternatively, the cup 11 can form a single piece with the threaded rod 8.
  • The cup 11 has a plurality of legs 100, regularly spaced, and projecting inside the cup 11, so as to allow the attachment of the product inside the cup 11. These legs 100 are obtained by molding with the cup 11. Such a characteristic is particularly advantageous when the product is poured directly into the cup.

La sortie et la rentrée du raisin 12 au travers de l'orifice de sortie 30, en vue d'une utilisation, respectivement, après utilisation, se font de la même manière que dans le mode de réalisation précédent, en entraínant l'organe de manoeuvre 4 en rotation par rapport à la chemise 2. En cas de surpression à l'intérieur de la chemise 2 entre la zone d'étanchéité haute 29 et la zone d'étanchéité basse 44, notamment à la fermeture du capot 27, le ressort 40 est comprimé (voir figure 2B), ce qui entraíne un recul axial de la cupule 11, de la tige filetée 8, et de l'écrou flottant 7. L'air est chassé par l'évent 43 ménagé dans le fond de l'organe de manoeuvre 4. The outlet and re-entry of the grape 12 through the outlet orifice 30, in view of use, respectively, after use, are done in the same way than in the previous embodiment, by training the maneuver 4 in rotation with respect to the jacket 2. In the event of overpressure at inside the jacket 2 between the upper sealing zone 29 and the zone low sealing 44, in particular when the cover 27 is closed, the spring 40 is compressed (see Figure 2B), which causes an axial recoil of the cup 11, the threaded rod 8, and of the floating nut 7. The air is expelled by the vent 43 formed in the bottom of the operating member 4.

Le mode de réalisation des figures 3A-3B, constitue une variante du mode de réalisation des figures 2A et 2B. Selon cette variante, une pièce de montage 104, est insérée à force à l'intérieur de l'organe de manoeuvre 4, une butée annulaire 111 limitant l'enfoncement de la pièce de montage 104 à l'intérieur de l'organe de manoeuvre 4. Sur cette pièce de montage 104 est claquée une pièce intermédiaire 105 (couplée en rotation avec 104), laquelle délimite un espace cylindrique dans laquelle est disposé le ressort 40. Une extrémité 41 du ressort 40 est en butée contre une portion annulaire 103 formée par la pièce de montage 104. L'autre extrémité 42 est en appui contre un écrou flottant 7, en engagement avec la tige filetée 8. Sous la force de rappel élastique du ressort 40, l'écrou est sensiblement en butée contre un épaulement 106 formé par la pièce intermédiaire 105. L'écrou 7 est couplé en rotation avec la pièce intermédiaire 105 (et donc avec l'organe de manoeuvre 4) via une portion 46 montée à coulisse à l'intérieur d'une rainure longitudinale 45 prévue sur la surface interne de la pièce intermédiaire 105.The embodiment of FIGS. 3A-3B constitutes a variant of the mode of realization of FIGS. 2A and 2B. According to this variant, a mounting part 104, is inserted by force inside the operating member 4, a stop annular 111 limiting the insertion of the mounting piece 104 inside the operating member 4. On this mounting piece 104 is slammed a intermediate piece 105 (coupled in rotation with 104), which defines a cylindrical space in which the spring 40 is arranged. One end 41 of the spring 40 abuts against an annular portion 103 formed by the piece of mounting 104. The other end 42 bears against a floating nut 7, in engagement with the threaded rod 8. Under the elastic return force of the spring 40, the nut is substantially in abutment against a shoulder 106 formed by the intermediate piece 105. The nut 7 is coupled in rotation with the piece intermediate 105 (and therefore with the operating member 4) via a portion 46 sliding mounted inside a longitudinal groove 45 provided on the internal surface of the intermediate piece 105.

Une tige filetée 8 de section non circulaire (sensiblement rectangulaire) sur au moins une partie de sa longueur, est montée en engagement avec l'écrou 7. La pièce intermédiaire 105 se prolonge par une partie de plus faible diamètre 107, sur laquelle est claquée une pièce de guidage 108. La pièce de guidage 108 est libre en rotation par rapport à la pièce intermédiaire 105. A cet effet, un bourrelet annulaire 109 est prévu sur la surface extérieure de la portion 107, et apte à coopérer avec une gorge annulaire 110 prévue sur la surface interne de la pièce de guidage 108. La pièce de guidage 108 se termine au dessus du bord libre 114 de la pièce intermédiaire 105, par une partie 112 repliée à 90°, laquelle forme un orifice 113 dont la section est de forme similaire à la section non circulaire de la tige filetée 8, de manière à en empêcher la rotation, tout en autorisant le mouvement axial. La chemise 2 est montée à force sur la pièce de guidage 108. La tige filetée 8 se termine par un plateau transversal 23 dont la périphérie extérieure porte un joint torique 44. Sur le plateau 23 est montée une cupule 11, laquelle est libre ou non en rotation par rapport au plateau 23. La cupule 11 est du même type que celle du mode de réalisation des figures 2A et 2B. Les autres parties du dispositif sont identiques aux parties correspondantes du mode de réalisation des figures 2A et 2B.A threaded rod 8 of non-circular (substantially rectangular) section on at at least part of its length, is mounted in engagement with the nut 7. The intermediate piece 105 is extended by a portion of smaller diameter 107, on which a guide piece 108 is slammed. The guide piece 108 is free to rotate relative to the intermediate piece 105. For this purpose, a annular bead 109 is provided on the outer surface of the portion 107, and able to cooperate with an annular groove 110 provided on the internal surface of the guide piece 108. The guide piece 108 ends above the free edge 114 of the intermediate piece 105, by a part 112 folded at 90 °, which forms an orifice 113 whose section is similar in shape to the section non-circular threaded rod 8, so as to prevent rotation, while allowing axial movement. Shirt 2 is force-fitted to the workpiece guide 108. The threaded rod 8 ends in a transverse plate 23, the outer periphery carries an O-ring 44. On the plate 23 is mounted a cup 11, which is free or not in rotation relative to the plate 23. The cup 11 is of the same type as that of the embodiment of FIGS. 2A and 2B. The other parts of the device are identical to the corresponding parts of the embodiment of FIGS. 2A and 2B.

Pour utiliser ce dispositif, l'utilisatrice enlève le capot 27. Elle entraíne l'organe de manoeuvre 4 en rotation par rapport à la chemise 2, ce qui provoque un entraínement de l'écrou 7 par rapport à la tige filetée 8, laquelle est immobile en rotation par rapport à la chemise 2. La tige filetée monte axialement à l'intérieur de la chemise et provoque la montée axiale de la cupule 11, jusqu'à ce que la surface libre 31 du raisin 12 émerge hors de la chemise 2, au travers de l'orifice de sortie 30. Après application, l'utilisatrice entraíne l'organe de manoeuvre 4 dans la direction opposée, de manière à faire descendre le raisin 12 à l'intérieur de la chemise 2. Elle referme ensuite le capot. En cas de surpression à l'intérieur de la chemise 2 entre la zone d'étanchéité haute 29 et la zone d'étanchéité basse 44, notamment à la fermeture du capot 27, le ressort 40 est comprimé (voir figure 3B), ce qui entraíne un recul axial de la cupule 11, de la tige filetée 8, et de l'écrou flottant 7. L'air est chassé par l'évent 43 ménagé dans le fond 47 de l'organe de manoeuvre 4.To use this device, the user removes the cover 27. She drives the organ maneuver 4 in rotation relative to the jacket 2, which causes a drive the nut 7 relative to the threaded rod 8, which is stationary in rotation relative to the jacket 2. The threaded rod rises axially to inside the shirt and causes the axial rise of the cup 11, up to that the free surface 31 of the grape 12 emerges out of the jacket 2, through outlet 30. After application, the user drives the maneuver 4 in the opposite direction, so that the grapes descend 12 inside the shirt 2. It then closes the cover. In case of overpressure inside the jacket 2 between the upper sealing zone 29 and the lower sealing zone 44, in particular when the cover 27 is closed, the spring 40 is compressed (see Figure 3B), which causes an axial recoil of the cup 11, threaded rod 8, and floating nut 7. Air is expelled by the vent 43 formed in the bottom 47 of the operating member 4.
