Abstract

The cap (5), e.g. for a supple tube dispenser (4) with ahead (7) having a flat cover (8) with a dispensing aperture (11), is connected to the head by a peripheral hinge (13), and is made in one piece with the tube by injection moulding from a thermoplastic material, with the foot (14) of the hinge inscribed within the circumference of the tube's skirt (6). The hinge is made from a thin portion of the moulded material extending between the periphery of the head and the periphery of the cap, and it incorporates a moulded spring to hold it in two stable positions - closed and open. The cap has a central peg (15) which blocks the dispensing aperture when closed.

Description

La présente invention est relative à une capsule de fermeture d'un récipient, comme par exemple un tube souple distributeur, du type comprenant, d'une part, un corps comportant une jupe inférieure et une tête fermée par un opercule muni d'au moins un orifice de distribution de produit destiné à être contenu dans le récipient, et d'autre part, un couvercle rabattable et articulé par une charnière implantée à la périphérie de ladite tête. The present invention relates to a closure cap for a container, such as for example a flexible dispensing tube, of the type comprising, on the one hand, a body comprising a lower skirt and a head closed by a cover provided with at least a product dispensing orifice intended to be contained in the container, and on the other hand, a hinged lid articulated by a hinge located at the periphery of said head.

La présente invention est également relative à un dispositif de moulage d'une telle capsule de fermeture. The present invention also relates to a device for molding such a closure cap.

Les tubes souples distributeurs couramment rencontrés comportent au niveau de leur partie supérieure, une capsule de fermeture dont l'orifice de distribution est obturé par un couvercle articulé par une charnière. Dans le cas où la capsule est obtenue d'une seule pièce par injection, les dimensions de l'orifice de distribution sont faibles et il n'est pas possible de choisir librement son emplacement. De plus, la charnière fait alors saillie à l'extérieur de la périphérie du corps de la capsule, ce qui pose des problèmes d'encombrement et de manipulation. The flexible dispensing tubes commonly encountered include at their upper part, a closure capsule whose dispensing orifice is closed by a cover hinged by a hinge. In the case where the capsule is obtained in one piece by injection, the dimensions of the dispensing orifice are small and it is not possible to freely choose its location. In addition, the hinge then protrudes outside the periphery of the body of the capsule, which poses problems of space and handling.

L'invention a pour but de fournir une capsule de fermeture d'un récipient qui remédie aux inconvénients mentionnés ci-dessus. The object of the invention is to provide a closure cap for a container which overcomes the drawbacks mentioned above.

A cet effet, l'invention a pour objet une capsule de fermeture d'un récipient, comme par exemple un tube souple distributeur, du type comprenant, d'une part, un corps comportant une jupe inférieure et une tête fermée par un opercule muni d'au moins un orifice de distribution de produit destiné à être contenu dans le récipient, et d'autre part, un couvercle rabattable et articulé par une charnière implantée à la périphérie de ladite tête, caractérisée en ce qu'elle est réalisée en une seule pièce par moulage par injection d'une matière thermoplastique et en ce que le pied de la charnière est inscrit à l'intérieur du pourtour de la jupe du corps. To this end, the subject of the invention is a closure cap for a container, such as for example a flexible dispensing tube, of the type comprising, on the one hand, a body comprising a lower skirt and a head closed by a cover provided at least one product dispensing orifice intended to be contained in the container, and on the other hand, a hinged lid articulated by a hinge located at the periphery of said head, characterized in that it is produced in a single piece by injection molding of a thermoplastic material and in that the foot of the hinge is inscribed inside the periphery of the skirt of the body.

La capsule de fermeture suivant l'invention peut comporter une ou plusieurs des caractéristiques suivantes
- la charnière est formée par un voile mince s'étendant entre la périphérie de la tête et la périphérie du couvercle
- la charnière est munie d'un ressort moulé de maintien du couvercle dans une première position écartée de la tête ou dans une seconde position rabattue sur ladite tête
- la capsule est à section transversale circulaire et présente au moins une diminution de diamètre, la tête formant le tronçon de plus faible diamètre
- le couvercle comporte sur sa face interne un doigt de section correspondant à la section de l'orifice de distribution et destiné à obturer ledit orifice dans la position rabattue du couvercle, ledit doigt étant venu de matière avec le couvercle
- le doigt comporte une collerette destinée à coopérer avec une gorge ménagée dans l'orifice de distribution ; et
- la tête est munie d'une encoche périphérique pour basculer le couvercle de la position rabattue vers la position écartée de la tête.The closure cap according to the invention may include one or more of the following characteristics
- the hinge is formed by a thin veil extending between the periphery of the head and the periphery of the cover
- The hinge is provided with a molded spring holding the cover in a first position away from the head or in a second position folded over said head
- The capsule is of circular cross section and has at least a decrease in diameter, the head forming the section of smaller diameter
- The cover has on its internal face a section finger corresponding to the section of the dispensing orifice and intended to close said orifice in the folded position of the cover, said finger having come integrally with the cover
- The finger has a flange intended to cooperate with a groove formed in the dispensing orifice; and
- The head is provided with a peripheral notch to tilt the cover from the folded position to the position away from the head.

L'invention a également pour objet un dispositif de moulage d'une capsule de fermeture telle que définie ci-dessus. The invention also relates to a device for molding a closure capsule as defined above.

Le dispositif de moulage suivant l'invention comprend
- un fond comportant sur sa face inférieure une empreinte de forme complémentaire à la forme de la face interne du couvercle, de la charnière et de la face externe de l'opercule de la tête,
- deux tiroirs de moulage déplaçables latéralement et situés au-dessous du fond, l'un des deux tiroirs comportant sur sa face supérieure une empreinte de forme complémentaire à la forme externe du couvercle et de la charnière et les deux tiroirs étant destinés chacun à donner la forme externe de la moitié du périmètre de la tête,
- un corps de moulage extérieur disposé au-dessous des deux tiroirs et comportant une cavité interne de forme complémentaire à la forme externe de la jupe,
- un noyau de moulage comportant à sa partie supérieure une empreinte de forme complémentaire à la forme de la face interne de l'opercule de la tête et ménageant avec les deux tiroirs et le corps de moulage un espace libre correspondant à la forme de la jupe, communiquant avec les empreintes,
- un dévêtisseur disposé au-dessous du corps de moulage et comportant un orifice de passage du noyau de moulage,
- et des moyens d'injection d'une matière thermoplastique dans l'espace libre et les empreintes.The molding device according to the invention comprises
a bottom comprising on its lower face an imprint of a shape complementary to the shape of the internal face of the cover, of the hinge and of the external face of the cover of the head,
- two moldable drawers laterally movable and located below the bottom, one of the two drawers having on its upper face an imprint of a shape complementary to the external shape of the cover and the hinge and the two drawers being each intended to give the external shape of half the perimeter of the head,
an external molding body arranged below the two drawers and comprising an internal cavity of shape complementary to the external shape of the skirt,
- a molding core having at its upper part an imprint of a shape complementary to the shape of the internal face of the cover of the head and providing with the two drawers and the molding body a free space corresponding to the shape of the skirt , communicating with the footprints,
a stripper placed below the molding body and comprising an orifice for the passage of the molding core,
- And means for injecting a thermoplastic material into the free space and the imprints.

Selon une autre caractéristique du dispositif de moulage, l'espace libre ménagé entre le corps de moulage et le noyau de moulage correspond à la forme d'un tube souple ditributeur venu de matière avec ladite capsule de fermeture. According to another characteristic of the molding device, the free space provided between the molding body and the molding core corresponds to the shape of a flexible tube distributor made of material with said closure capsule.

Un exemple de réalisation de l'invention va maintenant être décrit en regard des dessins annexés, sur lesquels
- la figure 1 est une vue en perspective d'un tube souple distributeur muni d'une capsule de fermeture suivant l'invention ;
- la figure 2 est une coupe longitudinale selon la ligne 11-11 de la figure 1 (dans laquelle le couvercle est ouvert à plat) de la capsule de fermeture, le couvercle étant en position ouverte (et fermée en traits mixtes)
- la figure 3 est une coupe longitudinale du dispositif de moulage suivant l'invention de la capsule de fermeture de la figure 2 ; et
- les figures 4 et 5 représentent des étapes de séparation des éléments constituant le dispositif représenté à la figure 3.An exemplary embodiment of the invention will now be described with reference to the accompanying drawings, in which
- Figure 1 is a perspective view of a flexible dispensing tube provided with a closure cap according to the invention;
- Figure 2 is a longitudinal section along line 11-11 of Figure 1 (in which the cover is open flat) of the closure capsule, the cover being in the open position (and closed in phantom)
- Figure 3 is a longitudinal section of the molding device according to the invention of the closure capsule of Figure 2; and
FIGS. 4 and 5 represent steps for separating the elements constituting the device shown in FIG. 3.

Le tube souple distributeur 1 en matière plastique et représenté à la figure 1 comporte un tube proprement dit 2 sur lequel est rapporté ou venu de matière une capsule de fermeture 3, également réalisée en matière plastique. The flexible dispensing tube 1 made of plastic and shown in FIG. 1 comprises a tube proper 2 on which is attached or come in material a closure capsule 3, also made of plastic.

La capsule de fermeture 3 obstrue l'extrémité supérieure du tube 2 alors que l'extrémité inférieure de ce corps est fermée par soudage de ses parois après que ce tube ait été rempli de produit par le fond. The closure capsule 3 obstructs the upper end of the tube 2 while the lower end of this body is closed by welding its walls after this tube has been filled with product from the bottom.

La capsule de fermeture (figure 2) par exemple à section circulaire, comprend un corps 4 et un couvercle rabattable 5. Le corps 4 possède une jupe inférieure 6 et une tête 7 fermée par un opercule 8. Le diamètre de la jupe 6 est supérieure à celui de la tête 7. The closure capsule (FIG. 2), for example of circular cross section, comprises a body 4 and a folding cover 5. The body 4 has a lower skirt 6 and a head 7 closed by a cover 8. The diameter of the skirt 6 is greater to that of the head 7.

La tête 7 est munie de deux encoches 9 et 10 diamètralement opposées qui s'étendent sur tout ou partie de la hauteur de cette tête. The head 7 is provided with two diametrically opposite notches 9 and 10 which extend over all or part of the height of this head.

L'opercule 8 est venu de matière en surplomb avec la tête 7, et comporte un épaulement 16 et un méplat 17. Cet opercule 8 possède un orifice de distribution 11.  The cover 8 has come in overhanging material with the head 7, and has a shoulder 16 and a flat 17. This cover 8 has a dispensing orifice 11.

Dans les parois de cet orifice est ménagée une gorge circulaire 12.In the walls of this orifice is formed a circular groove 12.

Le couvercle 5 est venu de matière avec la tête 7 du corps 4 de la capsule 3 par un voile mince 13 formant charnière. Le pied 14 de ce voile mince 13 est situé dans l'encoche 9, au niveau de l'extrémité supérieure de la tête 7, de manière à être situé dans le cylindre défini par la jupe 6 du corps 4 de la capsule 3. The cover 5 came integrally with the head 7 of the body 4 of the capsule 3 by a thin veil 13 forming a hinge. The foot 14 of this thin veil 13 is located in the notch 9, at the level of the upper end of the head 7, so as to be located in the cylinder defined by the skirt 6 of the body 4 of the capsule 3.

Ce voile mince 13 s'étend entre la périphérie de la réduction de diamètre 9 et la périphérie du couvercle 5, au niveau de la base de ce couvercle. This thin veil 13 extends between the periphery of the diameter reduction 9 and the periphery of the cover 5, at the base of this cover.

Le couvercle 5, de forme circulaire et à face interne concave, est muni d'un doigt 15 en saillie intérieure. Ce doigt 15, de diamètre égal au diamètre interne de l'orifice 11, porte une collerette 18 destinée à coopérer avec la gorge 12 de l'orifice. The cover 5, of circular shape and with a concave internal face, is provided with a finger 15 projecting from the inside. This finger 15, of diameter equal to the internal diameter of the orifice 11, carries a collar 18 intended to cooperate with the groove 12 of the orifice.

La base du couvercle 5 est par ailleurs de forme complémentaire de celle de l'opercule 8 de manière à pouvoir être rabattue sur celui-ci. The base of the cover 5 is moreover of complementary shape to that of the cover 8 so that it can be folded down thereon.

Par ailleurs, la charnière 13 peut être munie d'un ressort moulé afin de maintenir le couvercle 5 en position rabattue sur l'opercule 8 ou au contraire, en position ouverte. Furthermore, the hinge 13 may be provided with a molded spring in order to keep the cover 5 in the folded position on the cover 8 or, on the contrary, in the open position.

Enfin, l'encoche 10 permet l'ouverture du couvercle 5. Finally, the notch 10 allows the opening of the cover 5.

Le dispositif d'obtention de la capsule de fermeture 3 de tube distributeur 1 par moulage par injection en une seule pièce va maintenant être décrit en regard des figures 3 à 5. The device for obtaining the closure capsule 3 of the dispensing tube 1 by injection molding in a single piece will now be described with reference to FIGS. 3 to 5.

Ce dispositif de moulage comprend les éléments suivants
un fond 20, deux tiroirs de moulage 21 et 22, un corps de moulage extérieur 23, un noyau de moulage 24, un dévêtisseur 25 et des moyens d'injection (non repré sentés).This molding device comprises the following elements
a bottom 20, two molding drawers 21 and 22, an external molding body 23, a molding core 24, a stripper 25 and injection means (not shown).

Par convention, ce dispositif de moulage est orienté verticalement avec son fond 20 situé en partie supérieure, mais pour des questions de commodité, ce dispositif peut être de toute orientation. By convention, this molding device is oriented vertically with its bottom 20 located in the upper part, but for reasons of convenience, this device can be of any orientation.

La face inférieure du fond 20 comporte une empreinte 27 de forme complémentaire à celles des faces interne du couvercle 5 et du voile mince 13 et à celle de la face externe de l'opercule 8 de la tête 7. The underside of the bottom 20 has an imprint 27 of shape complementary to those of the inner faces of the cover 5 and of the thin web 13 and to that of the outer face of the cover 8 of the head 7.

Les deux tiroirs 21 et 22 sont situés audessous de ce fond 20 et sont déplaçables latéralement. The two drawers 21 and 22 are located below this bottom 20 and can be moved laterally.

Le tiroir 21 possède sur sa face supérieure une empreinte 28 de forme complémentaire à celle des faces externes du couvercle 5 et de la charnière 13. Ce tiroir 21 possède par ailleurs une face latérale munie d'une empreinte 29 de forme complémentaire à la moitié du périmètre de la tête 7 comportant l'encoche 9.The drawer 21 has on its upper face an imprint 28 of shape complementary to that of the external faces of the cover 5 and of the hinge 13. This drawer 21 also has a lateral face provided with an imprint 29 of shape complementary to half the perimeter of the head 7 comprising the notch 9.

La face latérale 30 du tiroir 22 est de forme complémentaire à la forme externe de l'autre moitié du périmètre de la tête 7, celle possédant l'encoche 10. The lateral face 30 of the drawer 22 is of shape complementary to the external shape of the other half of the perimeter of the head 7, that having the notch 10.

Au-dessous de ces tiroirs 21 et 22 est situé le corps de moulage 23 qui comporte une cavité interne 31 de forme complémentaire à la forme externe de la jupe 6 du corps 4 de la capsule de fermeture 3. Below these drawers 21 and 22 is located the molding body 23 which has an internal cavity 31 of a shape complementary to the external shape of the skirt 6 of the body 4 of the closure capsule 3.

Le noyau de moulage 24 possède au niveau de a partie supérieure une empreinte 35 de forme complémentaire à la forme de la face interne de la tête 7. Ce noyau de moulage défini avec les deux tiroirs 21 et 22 et avec le corps de moulage 23 un espace libre 32 dont la forme correspond à celle du corps 4 de la capsule de fermeture 3. Cet espace libre 32 communique avec l'espace libre 33 défini par le fond 20 et le tiroir 21 (destiné à donner la forme de couvercle). The molding core 24 has at the upper part an imprint 35 of shape complementary to the shape of the internal face of the head 7. This molding core defined with the two drawers 21 and 22 and with the molding body 23 a free space 32 whose shape corresponds to that of the body 4 of the closure capsule 3. This free space 32 communicates with the free space 33 defined by the bottom 20 and the drawer 21 (intended to give the form of cover).

Le dévêtisseur 25 est disposé au-dessous du corps de moulage 23 et possède un orifice de passage 34 du noyau de moulage 24. The stripper 25 is placed below the molding body 23 and has a through hole 34 in the molding core 24.

Après avoir mis en place les éléments adjacents du dispositif de moulage tels que décrits cidessus, l'injection de la matière thermoplastique à l'intérieur des espaces libres 32 et 33 est réalisée en mono-point ou en multi-points, soit au niveau de la tête de la capsule, soit au niveau de la partie inférieure de la jupe 6 de celle-ci. After having placed the adjacent elements of the molding device as described above, the injection of the thermoplastic material inside the free spaces 32 and 33 is carried out in single-point or in multi-point, ie at the head of the capsule, ie at the bottom of the skirt 6 thereof.

Après refroidissement de la pièce, on démoule (figure 4) les faces externes de l'opercule 8, du voile mince 13 ainsi que la face interne du couvercle 5 par séparation du fond d'empreinte 20 du reste du dispositif. After the part has cooled, the external faces of the cover 8, of the thin web 13 and the internal face of the cover 5 are removed from the mold (FIG. 4) by separation of the impression bottom 20 from the rest of the device.

Au cours de ce mouvement, on décolle le couvercle 5 du tiroir 21 afin de pouvoir dégager latéralement ce tiroir 21. Simultanément, le tiroir 22 est dégagé latéralement.During this movement, the cover 5 is removed from the drawer 21 in order to be able to release this drawer 21 laterally. Simultaneously, the drawer 22 is released laterally.

Les faces externes de la tête 7, du voile mince 13 et du couvercle 5 sont ainsi réalisées.The external faces of the head 7, the thin veil 13 and the cover 5 are thus produced.

Le démoulage de la capsule 3 se poursuit en rabattant le couvercle 5 sur l'opercule 8 (figure 5) afin de pouvoir dégager le noyau 24 et le dévêtisseur 25 portant la pièce moulée, en maintenant en place le corps de moulage extérieur 23 et les deux tiroirs 21, 22. La capsule de fermeture 3 est ensuite dégagée de ce noyau 24 par tous procédés connus. The demoulding of the capsule 3 continues by folding the cover 5 over the cover 8 (FIG. 5) so as to be able to disengage the core 24 and the stripper 25 carrying the molded part, keeping the external molding body 23 and the two drawers 21, 22. The closure cap 3 is then released from this core 24 by any known method.

Le dispositif de moulage est décrit ici pour réaliser une capsule de fermeture 3. Il est possible, en allongeant la jupe 6, c'est-à-dire en augmentant la longueur du corps de moulage extérieur 23, de réaliser le corps 2 du tube distributeur 1 de la figure 1. Ainsi, la capsule de fermeture 3 est venue de matière avec ce corps 2. The molding device is described here for producing a closure capsule 3. It is possible, by extending the skirt 6, that is to say by increasing the length of the external molding body 23, to produce the body 2 of the tube dispenser 1 in FIG. 1. Thus, the closure capsule 3 came integrally with this body 2.

Avantageusement, la charnière périphérique 13 ne fait pas saillie à l'extérieur du volume défini par la jupe 6 (grâce à l'encoche 9 de la tête 7) et permet de choisir librement les dimensions de l'orifice de distribution 11 de l'opercule 8.  Advantageously, the peripheral hinge 13 does not protrude outside the volume defined by the skirt 6 (thanks to the notch 9 of the head 7) and makes it possible to freely choose the dimensions of the dispensing orifice 11 of the cover 8.
