L'invention concerne un emballage distributeur notamment pour produit pâteux en forme de bâtonnet, comprenant un corps creux, un piston porteur dudit produit monté axialement mobile mais immobilisé en rotation dans le corps creux et pourvu d'une partie filetée, un dispositif de déplacement axial dudit piston comportant une vis qui s'étend axialement dans le corps et coopère avec la partie filetée du piston, et des moyens d'entraînement en rotation de la vis, qui comportent un organe en rotation de la vis, tel qu'une molette, disposé dans la partie inférieure du corps creux et porte sur sa face externe des éléments permettant son entraînement en rotation.The invention relates to a dispenser packaging, in particular for a pasty product in the form of a stick, comprising a hollow body, a piston carrying said product mounted axially mobile but immobilized in rotation in the hollow body and provided with a threaded part, an axial displacement device. of said piston comprising a screw which extends axially in the body and cooperates with the threaded part of the piston, and means for driving the screw in rotation, which comprise a member for rotating the screw, such as a knurl, arranged in the lower part of the hollow body and carries on its external face elements allowing its drive in rotation.

Dans les emballages distributeurs de ce type, qui sont connus, le corps creux présente une forme sensiblement cylindrique à section transversale circulaire et l'organe d'entraînement en rotation de la vis, en forme d'une molette qui provoque le déplacement axial du piston est montée au niveau de l'extrémité inférieure du corps, axialement alignée avec ce dernier et présente une forme cylindrique extérieure correspondant à celle du corps creux de façon que sa surface externe périphérique prolonge celle de ce corps. Il est ainsi aisé de faire tourner manuellement la molette étant donné que les éléments d'entraînement en rotation de celle-ci sont librement accessibles.In dispenser packages of this type, which are known, the hollow body has a substantially cylindrical shape with circular cross section and the member for driving the rotation of the screw, in the form of a wheel which causes the axial displacement of the piston. is mounted at the lower end of the body, axially aligned with the latter and has an outer cylindrical shape corresponding to that of the hollow body so that its peripheral external surface extends that of this body. It is thus easy to manually rotate the wheel since the rotational drive elements thereof are freely accessible.

L'emballage distributeur connu présente l'inconvénient majeur que ces éléments et dispositifs constitutifs lui imposent la forme cylindrique à section transversale circulaire.The known dispenser packaging has the major drawback that these constituent elements and devices impose on it the cylindrical shape with a circular cross section.

La présente invention a pour but de proposer un emballage distributeur qui peut avoir une forme autre que circulaire, par exemple ovale.The present invention aims to provide a dispenser packaging which may have a shape other than circular, for example oval.

Pour atteindre ce but, l'emballage distributeur selon l'invention est caractérisé en ce que les moyens d'entraînement en rotation de la molette comprennent un ruban sans fin qui est monté sur l'extrémité inférieure du corps, déplaçable dans le sens de la périphérie de celui-ci, comporte sur sa surface intérieure des éléments en saillie qui coopèrent avec des éléments d'entraînement sur la surface extérieure de la molette pour entraîner celle-ci en rotation lors du déplacement du ruban, et en ce que le corps creux, au niveau du ruban entraîneur, comprend des ouvertures permettant l'engagement des éléments d'entraînement complémentaires du ruban et de la molette.To achieve this object, the dispenser packaging according to the invention is characterized in that the means for driving the rotary wheel in rotation comprise an endless ribbon which is mounted on the lower end of the body, which can be moved in the direction of the periphery thereof, has on its inner surface projecting elements which cooperate with drive elements on the outer surface of the wheel to drive the latter in rotation during movement of the ribbon, and in that the hollow body , at the level of the driving ribbon, comprises openings allowing the engagement of the complementary driving elements of the ribbon and the wheel.

L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement dans la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels.The invention will be better understood and other objects, characteristics, details and advantages thereof will appear more clearly in the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating an embodiment. of the invention and in which.

La figure 1 est une vue latérale, partiellement en coupe axiale dans le plan longitudinal de son grand axe, d'un emballage distributeur selon la présente invention, de forme ovale.Figure 1 is a side view, partially in axial section in the longitudinal plane of its major axis, of a dispenser package according to the present invention, of oval shape.

La figure 2 est une vue similaire à la figure 1, dans un plan perpendiculaire à celui de cette figure.Figure 2 is a view similar to Figure 1, in a plane perpendicular to that of this figure.

La figure 3 est une vue de dessous de l'emballage selon la figure 1, et en coupe selon la figure III-III de la figure 1.Figure 3 is a bottom view of the package according to Figure 1, and in section according to Figure III-III of Figure 1.

La figure 4 est une vue en perspective et éclatée d'un certain nombre de parties essentielles de l'emballage selon la figure 1.Figure 4 is a perspective and exploded view of a number of essential parts of the package according to Figure 1.

La figure 5 est une vue en perspective et éclatée des organes nécessaires pour le déplacement du piston porteur du produit à distribuer.Figure 5 is a perspective and exploded view of the organs necessary for the displacement of the piston carrying the product to be dispensed.

La figure 6 est une vue en perspective et éclatée démontrant les parties de l'emballage selon l'invention, qui interviennent pour l'obturation de l'emballage à son extrémité supérieure.Figure 6 is a perspective and exploded view showing the parts of the packaging according to the invention, which are involved in closing the packaging at its upper end.

En se reportant aux figures, on constate que l'emballage distributeur représenté à titre d'exemple et notamment conçu pour un produit pâteux quelconque en forme de bâtonnet tel qu'un bâtonnet de déodorant, comprend essentiellement un corps creux extérieur 1, de forme allongée cylindrique à section transversale ovale, un corps intérieur 2, en forme d'une douille destiné à être placé à l'intérieur du corps 1 et également de forme ovale, un capuchon 3 destiné à fermer de façon étanche l'emballage à son extrémité supérieure, un piston 4 déplaçable axialement à l'intérieur du corps interne 2 et également de forme ovale et destiné à porter le bâtonnet (non représenté) ainsi qu'un agencement 5 qui est monté dans l'extrémité inférieure de l'emballage et adapté pour fermer celui-ci de façon étanche à cette extrémité et assurer le déplacement axial du piston 4. Les différentes pièces qui constituent l'emballage sont avantageusement réalisées en matière plastique de toute nature appropriée en fonction de la rigidité souhaitée.Referring to the figures, it can be seen that the distributor packaging shown by way of example and in particular designed for any pasty product in the form of a stick such as a deodorant stick, essentially comprises an external hollow body 1, of elongated shape. cylindrical with oval cross section, an inner body 2, in the form of a socket intended to be placed inside the body 1 and also of oval shape, a cap 3 intended to seal the packaging at its upper end , a piston 4 movable axially inside the internal body 2 and also of oval shape and intended to carry the stick (not shown) as well as an arrangement 5 which is mounted in the lower end of the packaging and suitable for close it tightly at this end and ensure the axial displacement of the piston 4. The various parts that make up the packaging are advantageously made of plastic material of any kind suitable according to the desired stiffness.

L'agencement 5 présente une structure relativement complexe, comme il ressort notamment des figures 4 et 5. Il comprend notamment un dispositif de déplacement axial en translation du piston 4, qui comporte une vis 9 s'étendant dans l'axe de l'emballage et pourvue à son extrémité inférieure d'un moyeu 10 en forme d'une couronne 11 rendue solidaire en rotation de la vis par des rayons 12, et une molette creuse 13 de forme cylindrique à section transversale circulaire, fermée en bas par une paroi de fond 16 et ouverte en haut, solidarisable en rotation du moyeu circulaire 10 et adaptée pour loger, de façon étanche, l'extrémité inférieure du corps interne 2 qui comprend à cette fin une portion cylindrique 14.The arrangement 5 has a relatively complex structure, as can be seen in particular from FIGS. 4 and 5. It comprises in particular a device for axial displacement in translation of the piston 4, which comprises a screw 9 extending in the axis of the packaging and provided at its lower end with a hub 10 in the form of a crown 11 made integral in rotation with the screw by spokes 12, and a hollow wheel 13 of cylindrical shape with circular cross section, closed at the bottom by a bottom wall 16 and open at the top, securable in rotation with the circular hub 10 and adapted to accommodate , in a sealed manner, the lower end of the internal body 2 which for this purpose comprises a cylindrical portion 14.

Plus précisément, la molette 13 comprend une couronne interne coaxiale 15 qui s'étend à partir de la paroi de fond 16 et est pourvue d'encoches axiales 17 destinées à recevoir chacune un rayon 12 du moyeu 10 lorsque ce dernier s'engage dans l'espace annulaire 19 formé entre la paroi externe 20 de la molette et la couronne 15. Comme le montre notamment les figures 1 à 3, c'est dans cet espace annulaire 19 aussi que s'engage la portion inférieure circulaire 14 du corps interne 2. Cette portion 14 porte sur sa surface périphérique externe un certain nombre de collerettes 22 coaxiales et axialement écartées qui constituent des lèvres d'étanchéité et viennent en contact avec la surface interne de la paroi 20 de la molette. Pour assurer l'assemblage de la molette 13 sur la portion 14 du corps interne, la molette comprend à son extrémité supérieure ouverte une nervure 23 qui fait radialement saillie vers l'intérieur et s'engage dans une rainure complémentaire circulaire 24 pratiquée dans la portion 14 au niveau de la naissance de celle-ci. Cette portion 14 comprend en outre, à son extrémité inférieure ouverte, une nervure 25 qui fait radialement saillie vers l'intérieur et s'engage dans une nervure complémentaire 26 pratiquée dans la surface périphérique externe du moyeu 10 et délimitée vers l'extrémité par une collerette d'assemblage 27 qui fait radialement saillie vers l'extérieur. L'extrémité supérieure du moyeu porte également un épaulement 29 qui fait radialement saillie vers l'extérieur et s'engage dans un évidement circulaire 30 du corps interne 2. Concernant la molette 13, il est encore à indiquer qu'elle porte sur la surface périphérique externe des éléments axiaux 31 en forme de dents qui sont régulièrement réparties autour de la périphérie et constituent des éléments permettant l'entraînement en rotation de la molette.More specifically, the wheel 13 comprises a coaxial internal ring 15 which extends from the bottom wall 16 and is provided with axial notches 17 each intended to receive a spoke 12 of the hub 10 when the latter engages in the annular space 19 formed between the external wall 20 of the wheel and the crown 15. As shown in particular in FIGS. 1 to 3, it is in this annular space 19 also that the circular lower portion 14 of the internal body 2 engages This portion 14 carries on its external peripheral surface a number of coaxial and axially spaced flanges 22 which constitute sealing lips and come into contact with the internal surface of the wall 20 of the wheel. To ensure the assembly of the wheel 13 on the portion 14 of the internal body, the wheel comprises at its open upper end a rib 23 which projects radially inwards and engages in a complementary circular groove 24 formed in the portion 14 at the level of its birth. This portion 14 further comprises, at its open lower end, a rib 25 which projects radially inwards and engages in a rib complementary 26 made in the outer peripheral surface of the hub 10 and delimited towards the end by an assembly flange 27 which projects radially outwards. The upper end of the hub also carries a shoulder 29 which projects radially outwards and engages in a circular recess 30 of the internal body 2. With regard to the wheel 13, it still has to be indicated that it bears on the surface external peripheral axial elements 31 in the form of teeth which are regularly distributed around the periphery and constitute elements allowing the rotary wheel to be driven.

Le dispositif d'entraînement en rotation de la molette 13 comprend un ruban 33 sans fin qui constitue une boucle en un matériau souple et entoure l'extrémité inférieure du corps externe 1. Ce dernier comprend à cette fin une rainure de guidage périphérique 34 dans lequel le ruban 33 est engagé et guidé pour pouvoir exécuter un déplacement en direction de son axe longitudinal dans le sens de la double flèche F1. Le ruban porte sur sa surface interne des éléments en saillie 36 en forme de dents qui s'étendent parallèlement aux dents 31 de la molette 13 et constituent une denture complémentaire à celle de la molette pour pouvoir engrèner celle-ci. Pour que la denture 36 du ruban 33 puisse venir en engagement avec la denture 31 de la molette 13, la paroi formant le fond de la rainure de guidage 34 comprend au niveau du petit axe deux lumières 38. Comme le montre notamment la figure 4, lorsque la molette 13 est introduite à travers l'ouverture circulaire 39 pratiquée dans la paroi de fermeture ovale 40 de l'extrémité inférieure du corps externe 1, de façon que sa paroi de fond 16 se trouve dans le plan de la paroi 40, l'engagement mutuel des dentures 36 et 31 respectivement du ruban 33 et de la molette 13 est assuré. Lorsque l'on déplace le ruban sur l'extrémité inférieure du corps 1, celui-ci entraîne en rotation la molette 13, ce qui provoque la rotation de la vis 9 et ainsi le déplacement axial du piston 4.The device for rotating the wheel 13 comprises an endless ribbon 33 which constitutes a loop of flexible material and surrounds the lower end of the external body 1. The latter comprises for this purpose a peripheral guide groove 34 in which the ribbon 33 is engaged and guided in order to be able to move in the direction of its longitudinal axis in the direction of the double arrow F1. The ribbon carries on its internal surface projecting elements 36 in the form of teeth which extend parallel to the teeth 31 of the wheel 13 and constitute a toothing complementary to that of the wheel in order to be able to mesh the latter. So that the teeth 36 of the ribbon 33 can come into engagement with the teeth 31 of the thumb wheel 13, the wall forming the bottom of the guide groove 34 comprises at the minor axis two slots 38. As shown in particular in FIG. 4, when the thumbwheel 13 is inserted through the circular opening 39 made in the oval closing wall 40 of the lower end of the external body 1, so that its bottom wall 16 is in the plane of the wall 40, l mutual commitment teeth 36 and 31 respectively of the ribbon 33 and the wheel 13 is ensured. When the ribbon is moved over the lower end of the body 1, the latter rotates the thumb wheel 13, which causes the screw 9 to rotate and thus the axial displacement of the piston 4.

En se reportant aux figures 1 et 2 et 6, on constate que le capuchon 3 présente également une forme ovale correspondant à celle de l'extrémité supérieure du corps interne 2 pour pouvoir être emmanchée sur celle-ci dans sa position de fermeture. Le dispositif 7 de verrouillage du capuchon 3 dans sa position de fermeture comprend essentiellement un ruban sans fin 42, en forme d'une boucle, réalisé en un matériau souple et placé dans une rainure annulaire 43 qui est pratiqué dans la surface périphérique extérieure de la paroi du capuchon et s'étend perpendiculairement à l'axe de l'emballage tout autour du capuchon. Ce ruban comprend sur sa surface interne, disposées en vis-à-vis, deux rampes 44 de verrouillage destinées à coopérer avec deux rampes complémentaires 45 qui font saillie de la surface périphérique extérieure du corps interne 2 de façon à pouvoir coopérer avec les rampes 44 lors du déplacement du ruban 42 dans la direction de la double flèche F2. Pour que les rampes 44 et 45 puissent venir en engagement mutuel, le fond de l'évidement périphérique de guidage 43 du capuchon 3 comporte deux lumières 46 d'une longueur périphérique et d'une largeur appropriée.Referring to Figures 1 and 2 and 6, we see that the cap 3 also has an oval shape corresponding to that of the upper end of the inner body 2 to be able to be fitted thereon in its closed position. The device 7 for locking the cap 3 in its closed position essentially comprises an endless ribbon 42, in the form of a loop, made of a flexible material and placed in an annular groove 43 which is formed in the outer peripheral surface of the wall of the cap and extends perpendicular to the axis of the package all around the cap. This strip comprises on its internal surface, disposed vis-a-vis, two locking ramps 44 intended to cooperate with two complementary ramps 45 which project from the external peripheral surface of the internal body 2 so as to be able to cooperate with the ramps 44 when moving the ribbon 42 in the direction of the double arrow F2. So that the ramps 44 and 45 can come into mutual engagement, the bottom of the peripheral guide recess 43 of the cap 3 has two slots 46 of peripheral length and of appropriate width.

Les rampes 44 et 45 comportent chacune une portion circonférentielle respectivement 48 et 49 et une portion respectivement 50 et 51 qui s'étend parallèlement à l'axe de l'emballage. Les zones d'extrémité libres des portions circonférentielles 48 et 49 des rampes 44 et 45 présentent un profil incliné de façon que le déplacement du ruban 42 en direction de la flèche F2 provoque, après la mise en place du capuchon 3 sur l'extrémité du corps interne et l'engagement mutuel des rampes, un déplacement axial du capuchon sur l'extrémité du corps 2, dans une direction jusqu'au verrouillage du capuchon et dans l'autre direction jusqu'à une position permettant le dégagement du capuchon. Les portions 50 et 51 des rampes déterminent les positions extrêmes du déplacement du ruban.The ramps 44 and 45 each have a circumferential portion 48 and 49 respectively and a portion 50 and 51 respectively which extends parallel to the axis of the packaging. The free end zones of the circumferential portions 48 and 49 of the ramps 44 and 45 have an inclined profile so that the displacement of the ribbon 42 in the direction of the arrow F2 causes, after the fitting of the cap 3 on the end of the internal body and the mutual engagement of the ramps, an axial displacement of the cap on the end of the body 2, in one direction until the cap is locked and in the other direction to a position allowing the cap to be released. The portions 50 and 51 of the ramps determine the extreme positions of the displacement of the ribbon.

Il est à noter que pour assurer la fermeture étanche du capuchon, l'extrémité supérieure de celui-ci est adaptée pour qu'elle s'applique à force contre la face interne au niveau du fond du capuchon.It should be noted that in order to ensure the tight closure of the cap, the upper end of the latter is adapted so that it presses against the internal face at the level of the bottom of the cap.

Concernant le fonctionnement de l'emballage du distributeur, il ressort de la description qui précède, que pour le déplacement axial du piston 4 porteur du bâtonnet de produit cosmétique et pour le verrouillage du capuchon il suffit de déplacer de façon appropriée respectivement les rubans 33 et 42. Etant donné que les rubans sont souples, l'emballage peut avoir une autre forme que la forme circulaire des emballages habituels et aussi une autre forme que la forme ovale de l'emballage qui vient d'être décrit en se référant aux figures.Regarding the operation of the packaging of the dispenser, it emerges from the above description, that for the axial displacement of the piston 4 carrying the stick of cosmetic product and for locking the cap, it suffices to move the ribbons 33 and 42. Since the ribbons are flexible, the packaging may have another shape than the circular shape of the usual packaging and also another shape than the oval shape of the packaging which has just been described with reference to the figures.

Etant donné que les différentes pièces constitutives de l'emballage sont réalisées en matière plastique, toutes les saillies, nervures, rainures et dents ou analogues peuvent être réalisés lors du moulage de ces pièces. La configuration des pièces, telle qu'elle est représentée permet un assemblage aisé de l'emballage et la réalisation du bâtonnet pâteux par moulage à l'intérieur de l'emballage en introduisant le produit à partir de l'extrémité inférieure avant la mise en place de la molette 13 qui constitue également le bouchon de fermeture de l'emballage. Bien entendu, le capuchon 3 aura été verrouillé auparavant dans sa position de fermeture étanche sur le corps creux de l'emballage. Concernant les rubans verrous, ils sont réalisés avantageusement en élastomère ou en matériau thermoplastique souple et portent sur leurs surfaces extérieures de godrons ergonomiques.Since the various constituent parts of the packaging are made of plastic, all the projections, ribs, grooves and teeth or the like can be made during the molding of these parts. The configuration of the parts, as shown, allows easy assembly of the packaging and the production of the pasty stick by molding. inside the packaging by introducing the product from the lower end before the setting up of the thumbwheel 13 which also constitutes the closure cap of the packaging. Of course, the cap 3 will have been locked before in its sealed closure position on the hollow body of the package. Regarding the locking ribbons, they are advantageously made of elastomer or flexible thermoplastic material and bear ergonomic gadroons on their outer surfaces.
