Abstract

The perforating stopper is for a distributor blocked by a membrane. A mobile thrust projection forms a point with a threaded distributor body. The thrust point (8) has a projection on a cylindrical body (13). A shoulder stop (12) can slide in a recess (14) over the base (4). This acts as a stop on the end face of the distributor (5) and locks against a locking ring (15) placed radially in a projection on the inner face of the recess. The base - thrust point (8) joint has a breakable connection between the shoulder stop and recess entry.

Description

L'invention concerne des bouchons perforateurs du genre décrit au brevet français NO 1 248 097 du 30 Octobre 1959, destinés à s'adapter sur un ajutage distributeur, initialement obturé par une membrane et comportant un moyen de perforation de cette membrane avec un poussoir mobile comportant en regard de la membrane à perforer une partie formant poin çon, le poussoir présentant, d'autre part, une structure appropriée pour constituer une filière de profil désiré quelconque après perforation de la membrane. The invention relates to perforator plugs of the type described in French patent NO 1 248 097 of October 30, 1959, intended to be fitted on a distributor nozzle, initially closed by a membrane and comprising a means of perforating this membrane with a movable pusher comprising, opposite the membrane to be perforated, a part forming a punch, the pusher having, on the other hand, a structure suitable for constituting a die of any desired profile after perforation of the membrane.

Selon le développement de l'addition NO 78 208 rattachée audit brevet, la filière est constituée par le poussoir luimême, des moyens étant prévus pour immobiliser le poussoir, après défonçage de la membrane au débouché de l'ajutage associé. According to the development of the addition NO 78 208 attached to said patent, the die is constituted by the pusher itself, means being provided for immobilizing the pusher, after knocking down the membrane at the outlet of the associated nozzle.

Cette immobilisation était assurée par enclenchement d' une partie radialement saillante du poussoir derrière un rebord de retenue ménagé à cet effet à lå sortie de l'ajutage. This immobilization was ensured by engaging a radially projecting part of the pusher behind a retaining flange formed for this purpose at the outlet of the nozzle.

Ce rebord de retenue était avantageusement constitué par un bord rentrant d'une embase adaptée à coiffer l'ajutage distributeur, un moyen étant prévu en outre pour limiter le degré d'enfoncement du poussoir. This retaining rim was advantageously constituted by a re-entrant edge of a base adapted to cover the distributor nozzle, a means being further provided for limiting the degree of depression of the pusher.

Les bouchons perforateurs ainsi conçus rencontrent un grand succès dans la pratique et ont fait l'objet d'un important développement industriel et commercial. L'expérience a montré cependant que la réalisation par moulage en matière plastique de ce type de bouchons nécessitait la mise en oeuvre d'un moulage en coquille de la partie poussoir, en raison de la partie radialement saillante qui était nécessaire pour assurer l'immobilisation du poussoir derrière le rebord de retenue constitué par un bord rentrant de l'embase. The perforator caps thus designed have met with great success in practice and have been the subject of significant industrial and commercial development. Experience has shown, however, that the production by plastic molding of this type of plug requires the use of a shell molding of the pusher part, because of the radially projecting part which was necessary to ensure immobilization. the pusher behind the retaining rim constituted by a re-entrant edge of the base.

La présente invention a pour objet d'éviter cette source de complication, en rendant possible la fabrication des bouchons perforateurs du genre considéré, par la mise en oeuvre d'une matrice unique, ce qui permet une réduction des frais d'outillage, tout en augmentant la cadence de production. The object of the present invention is to avoid this source of complication, by making it possible to manufacture perforator plugs of the type under consideration, by using a single die, which allows a reduction in tooling costs, while increasing the production rate.

Ces résultats sont obtenus, selon l'invention, grace au confinement de la surface radialement externe du poussoir, a l'intérieur d'un prolongement de la surface interne de l'embase et par l'aménagement sur cette surface interne de l'embase elle-même, d'un élément de retenue avantageusement constitué par un épaulement radial saillant vers l'intérieur avec une face inclinée du côté de l'entrée de la cheminée de guidage de l'embase et une face droite du côté opposé. These results are obtained, according to the invention, thanks to the confinement of the radially external surface of the pusher, inside an extension of the internal surface of the base and by the arrangement on this internal surface of the base. itself, of a retaining element advantageously constituted by a radial shoulder projecting inwards with an inclined face on the side of the inlet of the guide chimney of the base and a straight face on the opposite side.

Les caractéristiques et avantages de 11 invention ressortiront d'ailleurs de la description qui va suivre en référence aux dessins annexés où :
la figure 1 est une -vue en coupe de l'ensemble embase poussoir en cours de moulage ;
la figure 2 est une vue en coupe du bouchon selon l'in- vention en place sur un récipient tubulaire souple, après mi5e en oeuvre du poussoir défonceur. The characteristics and advantages of the invention will become apparent from the description which follows with reference to the appended drawings in which:
Figure 1 is a sectional view of the pusher base assembly during molding;
Figure 2 is a sectional view of the plug according to the invention in place on a flexible tubular container, after mi5e implementation of the ripper plunger.

Le bouchon comporte un corps creux 1 formant d'un oete d'une cloison transversale 2, un écrou adapte à se visser sur la partie filetée 3 d'une embase 4 pièce moulée en matière plastique Cette embase est fixée sur l'ajutage 5 d'un réci- pient tubulaire souple 6 par tout moyen approprié (vissage, collage, encliquetage, etc ...). L'ajutage 5 est initialement obturé par une membrane 7 qui est destinée à autre défoncée, comme il est visible sur la figure 2, par un poussoir défon- ceur 8. The plug comprises a hollow body 1 forming a head of a transverse partition 2, a nut adapted to be screwed onto the threaded part 3 of a base 4 molded plastic part This base is fixed to the nozzle 5 d 'a flexible tubular container 6 by any suitable means (screwing, gluing, snap-fastening, etc.). The nozzle 5 is initially closed by a diaphragm 7 which is intended for another knockout, as can be seen in FIG. 2, by a knockout push-button 8.

Ce poussoir défonceur est constitué de manière connue en soi avec un corps présentant en coupe transversale une série de lumières de guidage de l'écoulement de façon à constituer une filière de distribution de la matière contenue dans le récipient selon un profil en étoile ou tout autre profil. Ce poussoir comporte à sa partie inférieure un tronçon -tersinal annulaire 10 limité par un plan incliné et une arete vive formant de façon connue en soin un poinçon défonceur en regard de la membrane 7.En partant de bas en haut de ce tronçon terminal cylindrique 10 le poussoir comporte successivement une partie divergente 11, un épaulement 12 que l'on voit sur la figure 2 en appui sur la face frontale de l'ajutage 5, et une partie cylindrique 13. This ripper pusher is constituted in a manner known per se with a body having in cross section a series of flow guide lights so as to constitute a distribution channel for the material contained in the container according to a star profile or any other profile. This pusher comprises at its lower part an annular -terisinal section 10 limited by an inclined plane and a sharp edge forming in a known manner in care a knockout punch facing the membrane 7. Starting from the bottom of this cylindrical end section 10 the pusher successively comprises a divergent part 11, a shoulder 12 which can be seen in FIG. 2 bearing on the front face of the nozzle 5, and a cylindrical part 13.

L'embase 4 comporte de son côté, au-dessus de la partie filetée 3, une cheminée 14 qui surmonte l'ajutage 5. Cette cheminée présente une surface interne de forme cylindrique se plaçant sensiblement en prolongement de la surface externe de l'ajutage 5 et, en saillie sur cette surface interne, une bague de verrouillage 15 délimitée par une face interne droite et une face externe inclinée. Sur la figure 2 on voit l'épaulement 12 du poussoir emprisonné entre la face frontale de l'ajutage 5 et la face interne droite de la bague 15. On voit que la hauteur radiale de cette bague 15 est légère- ment inférieure à la différence des rayons de la surface interne de la cheminée 14 et de la surface externe de la partie cylindrique 13 du poussoir 8.De son côté, l'épaulement 12 du poussoir présente un diamètre supérieur au diamètre interne de la bague 15 et inférieur ou égal au diamètre interne de la cheminée 14. The base 4 has, for its part, above the threaded part 3, a chimney 14 which surmounts the nozzle 5. This chimney has an internal surface of cylindrical shape placed substantially as an extension of the external surface of the nozzle 5 and, projecting from this internal surface, a locking ring 15 delimited by a straight internal face and an inclined external face. In Figure 2 we see the shoulder 12 of the pusher trapped between the front face of the nozzle 5 and the right inner face of the ring 15. We see that the radial height of this ring 15 is slightly less than the difference radii of the internal surface of the chimney 14 and of the external surface of the cylindrical part 13 of the pusher 8. On the other hand, the shoulder 12 of the pusher has a diameter greater than the internal diameter of the ring 15 and less than or equal to the internal diameter of the chimney 14.

Ainsi qu'il est visible sur la figure 1, l'embase 4, d' une part, et le poussoir 8, d'autre part, sont réalisés par moulage en une seule pièce dans un moule comportant une partie inférieure 21 équipée d'une broche en deux parties coaxiales 22et23 et une partie supérieure ou matrice 24 ellemême équipée d'une broche 25. As can be seen in FIG. 1, the base 4, on the one hand, and the pusher 8, on the other hand, are produced by molding in one piece in a mold comprising a lower part 21 fitted with a spindle in two coaxial parts 22 and 23 and an upper part or die 24 itself equipped with a spindle 25.

A la jonction entre la partie terminale de la broche 23 et le fond de la matrice 24 on ménage une série d'intervalles pour l'établissement d'une série de ponts de liaison frangibles 26 entre l'épaulement 12 du poussoir 8 et le pourtour de l'entrée de la cheminée 14 de l'embase 4. At the junction between the terminal part of the spindle 23 and the bottom of the die 24, a series of intervals is provided for the establishment of a series of frangible connecting bridges 26 between the shoulder 12 of the pusher 8 and the periphery from the inlet of the chimney 14 of the base 4.

On voit que dans ces conditions, le moulage de l'ensemble embase-poussoir devient possible avec une matrice 24 sans que le démoulage pose de probleme.  It can be seen that under these conditions, the molding of the base-pusher assembly becomes possible with a die 24 without demolding being a problem.

Après dégagement de la broche 25 on met en rotation la broche 22-23 avec pour effet de dévisser l'ensemble 4-8 de la matrice 24. On dégage ensuite la broche 22-23, l'embase 4 trouvant appui sur la plaque 21, après quoi la pièce 4-8 se libère. After disengaging the spindle 25, the spindle 22-23 is rotated with the effect of unscrewing the assembly 4-8 from the die 24. The spindle 22-23 is then released, the base 4 being supported on the plate 21 , after which piece 4-8 is released.

L'ensemble embase-poussoir étant fixé sur l'ajutage 5, le bouchon 1 ést vissé sur le filetage 3 jusqu'à un niveau intermédiaire tel qu'indiqué en X-X de la figure 2, niveau déterminé eventuellement par une rondelle en carton ou analogue, où la cloison transversale 2 du bouchon arrive juste au contact de la face supérieure du poussoir 8. C'est au premier usage de l!emballage que le vissage se poursuit de façon usuelle pour provoquer le défonçage de la membrane 7 par pénétration du poussoir dans la cheminée 14 après dEchi- rement des ponts de liaison 26, suivi du franchissement de la bague de verrouillage 15 par l'épaulement 12 et immobilisation de celui-ci dans la position Illustrée à la figure -2.  The plunger base assembly being fixed on the nozzle 5, the plug 1 is screwed onto the thread 3 up to an intermediate level as indicated in XX of FIG. 2, level possibly determined by a cardboard washer or the like , where the transverse partition 2 of the plug comes just into contact with the upper face of the pusher 8. It is at the first use of the packaging that the screwing continues in the usual way to cause the knockout of the membrane 7 by penetration of the pusher in the chimney 14 after tearing of the connecting bridges 26, followed by the crossing of the locking ring 15 by the shoulder 12 and immobilization of the latter in the position illustrated in FIG. -2.
