Description

La présente invention concerne les emballages distributeurs du genre comportant un ajutage normalement obturé par un bouchon en forme de capuchon et plus particulièrement les ajutages operculés dont l'opercule est destiné à être défoncé au premier usage au moyen d'un bouchon muni à cet effet d'un poinçon approprié.The present invention relates to dispenser packaging of the kind comprising a nozzle normally closed by a cap-shaped stopper and more particularly the sealed nozzles, the cover of which is intended to be broken open at first use by means of a stopper provided for this purpose. '' a suitable punch.

Les ajutages de ce genre sont habituellement fabriqués en métal, à base d'aluminium en particulier, mais dans certaines applications, la nécessité s'est fait sentir de réaliser des ajutages en matière plastique en raison d'inconvénients attribués à des interactions chimiques indésirables entre le produit à distribuer et le corps d'ajutage, et plus spécialement l'opercule métallique.Nozzles of this kind are usually made of metal, especially aluminum, but in some applications there has been a need to make plastic nozzles due to disadvantages attributed to undesirable chemical interactions between the product to be dispensed and the nozzle body, and more particularly the metal cover.

Or, la fabrication d'ajutages operculés par moulage dans les matières plastiques usuelles s'est heurtée à des difficultés résultant des propriétés mécaniques de ces matières ; l'opercule réalisé en matière plastique présente l'inconvénient qu'après son déchirement par le poinçon défonceur usuel il tend à reprendre sa forme et sa place initiale en se remettant ainsi en travers de l'ajutage ce qui perturbe un écoulement régulier du produit.However, the manufacture of nozzles sealed by molding in the usual plastics has encountered difficulties resulting from the mechanical properties of these materials; the cover made of plastic has the disadvantage that after tearing thereof by conventional digger punch it tends to regain its shape and its initial place by calling into the nozzle through which disturbs a regular flow m ent product.

La présente invention a pour objet la création d'un ajutage operculé se prêtant à la fabrication par moulage en une matière plastique usuelle tout en échappant à cet inconvénient.The present invention relates to the creation of a sealed nozzle suitable for manufacturing by molding in a usual plastic material while avoiding this drawback.

L'invention offre à cet effet un ajutage operculé essentiellement caractérisé en ce que des lignes radiales d'affaiblissement déterminant dans l'opercule une pluralité de secteurs, des boutons d'arret ménagés en saillie sur la face dorsale de certains au moins de ces secteurs sont adaptés à coopérer en vue d'un verrouillage par emboîtement avec des boutonnières ménagées en creux dans la paroi interne de l'em- bout.The invention provides for this purpose a sealed nozzle essentially characterized in that radial lines weakening determining in the cover a plurality of sectors, stop buttons protruding from the dorsal face of at least some of these sectors are adapted to cooperate with a view to interlocking with buttonholes formed in hollow in the inner wall of e m - end.

Grâce à cette disposition, sous l'action du poinçon du bouchon défonceur, l'opercule, se déchirant selon les lignes radiales d'affaiblissement ménagées à cet effet,se trouve divisé en une série de secteurs qui demeurent rattachés à l'embout par leur bord périphérique, mais une fois rabattus par la progression du poinçon défonceur demeurent immobilisés au contact de la paroi interne de l'embout grâce à l'effet de verrouillage résultant de l'emboîtement de leur bouton dorsal dans les boutonnières correspondantes.With this arrangement, under the action of the punch Digger cap, the lid, tearing according to the radial lines of weakness provided for this e ff and is divided into a series of areas that remain attached to the nozzle by their peripheral edge, but once folded down by the progression of the hammer punch remain immobilized in contact with the internal wall of the endpiece thanks to the locking effect resulting from the fitting of their back button in the corresponding buttonholes.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre donnée à titre d'exemple, en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective d'un ajutage selon l'invention et d'un bouchon perforateur associé ;
  • la figure 2 est une vue en perspective de l'intérieur de l'ajutage en coupe ;
  • les figures 3 à 5 sont des vues en coupe diamétrale de l'ajutage montrant trois états successifs de celui-ci respectivement avant, pendant et après la première opération de vissage du bouchon ;
  • la figure 6 est une vue de détail du verrouillage d'un secteur de l'opercule ;
  • la figure 7 est une vue semblable montrant une variante de réalisation.
The characteristics and advantages of the invention will become apparent from the description which follows given by way of example, with reference to the accompanying drawings in which:
  • Figure 1 is a perspective view of a nozzle according to the invention and an associated perforator plug;
  • Figure 2 is a perspective view of the interior of the nozzle in section;
  • Figures 3 to 5 are diametrical sectional views of the nozzle showing three successive states thereof respective m ent before, during and after the first operation of screwing the cap;
  • Figure 6 is a detail view of the locking of a sector of the cover;
  • Figure 7 is a similar view showing an alternative embodiment.

Suivant la forme de réalisation choisie et représentée figure 1 l'ajutage disposé en bout d'un emballage distributeur compressible, par exemple tubulaire (non détaillé) 10 comporte de manière connue en soi une embase Il de raccordement supportant un embout 12 de forme générale cylindrique avec un filetage s'étendant depuis l'embase 11 jusqu'à la face terminale qui est obturée par une membrane formant opercule 14. cet ajutage est destiné à coopérer de façon usuelle avec un bouchon 15 adapté à se visser sur l'embout tubulaire 12 et équipé d'un poinçon défonceur 16.According to the embodiment chosen and shown in Figure 1 the nozzle disposed at the end of a compressible dispenser packaging, for example tubular (not detailed) 10 comprises in known manner a connection base II supporting a nozzle 1 2 of general shape cylindrical with a thread extending from the base 11 to the end face which is closed by a membrane forming a cover 14. this nozzle is intended to cooperate in the usual way with a plug 1 5 adapted to be screwed onto the tubular endpiece 12 and equipped with a knockout punch 16.

Ainsi qu'il est mieux visible sur la figure 2 la membrane 14 fermant l'opercule présente sur sa face dorsale une série de rainures radiales d'affaiblissement 18 au nombre de six dans le cas de l'exemple considéré, subdivisant la membrane en autant de secteurs tels que 19. En saillie sur la face dorsale de chacun de ces secteurs est ménagé un bouton tel que 21 se situant dans un plan radial dans lequel la paroi interne adjacente de l'embout présente de son côté un dégagement tel que 22 adapté à former une boutonnière de verrouillage par emboîtement du bouton.As is better visible in FIG. 2, the membrane 1 4 closing the cover has on its dorsal face a series of radial weakening grooves 18, six in number in the case of the example considered, subdividing the membrane into as many sectors as 19. Projecting on the dorsal face of each of these sectors is provided a button such as 2 1 lying in a radial plane in which the adjacent internal wall of the end piece has on its side a clearance such that 22 adapted to form a locking buttonhole e m m box button ent.

Comme il est visible sur la figure, l'épaisseur de la paroi de l'embout peut avantageusement être augmentée d'une quantité correspondante dans la partie initiale 23 sur une hauteur qui peut être limitée par exemple à une valeur voisine de celle du rayon de l'opercule.As can be seen in the figure, the thickness of the wall of the end piece can advantageously be increased by a corresponding amount in the initial part 23 over a height which can be limited, for example, to a value close to that of the radius of the cover.

Les figures 3 à 5 montrent trois états successifs de l'ajutage respectivement avant, pendant et après le premier usage.Figures 3 to 5 show three successive states of the nozzle respectively before, during and after the first use.

Sur la figure 3 on retrouve la vue en coupe de l'embout 12 surmonté du bouchon défonceur 15 muni de son poinçon usuel 16.In FIG. 3 we find the sectional view of the end piece 12 surmounted by the knockout plug 15 provided with its usual punch 16.

Sur la figure 4 le bouchon ayant été vissé à fond sur l' embout 12 l'opercule s'est trouvé défoncé et rabattu contre la partie adjacente de la paroi interne.In Figure 4 the plug having been screwed fully on the tip 12 the cover was smashed and folded against the adjacent part of the inner wall.

Comme il est visible sur la figure 5 après dévissage du bouchon perforateur 15 les divers secteurs 19 de l'opercule se trouvent immobilisés dans leur position rabattue en raison du verrouillage par emboîtement de leur bouton dorsal 21 dans une boutonnière 22 associée.As can be seen in FIG. 5 after unscrewing the perforating plug 15, the various sectors 19 of the cover are immobilized in their folded position due to the locking by interlocking of their back button 21 in an associated buttonhole 22.

La figure 6 est une vue de détail montrant qu'en vue d'un verrouillage plus efficace la boutonnière 22 peut avantageusement présenter une section transversale évasée avec une entrée rétrécie dont le franchissement impliquera une compression suivie d'une détente élastique du bouton, l'effort nécessaire à cet effet pouvant être fourni sans aucune difficulté par l'action du poinçon défonceur.Figure 6 is a detail view showing that for a more effective locking buttonhole 22 may advantageously have a flared cross section with a narrowed entry whose crossing will involve compression followed by elastic relaxation of the button, the effort required for this purpose can be provided without any difficulty by the action of the hammer punch.

Selon la variante indiquée sur la figure 7 on a adopté pour l'entrée de l'embout et pour l'opercule une forme polygonale, les lignes d'affaiblissement 18' partant des sommets du polygone tandis que les côtés de celui-ci forment des charnières d'articulation rectilignes pour les secteurs 19' de forme triangulaire ainsi constitués.According to the variant indicated in FIG. 7, a polygonal shape has been adopted for the entry of the endpiece and for the cover, the weakening lines 18 ′ starting from the vertices of the polygon while the sides thereof form rectilinear articulation hinges for the sectors 19 'of triangular shape thus formed.

L'invention n'est, bien entendu,, pas limitée aux détails des formes de réalisation décrites à titre d'exemples, mais se prête au contraire à diverses modalités de mise en oeuvre. Ainsi, par exemple, l'ajutage peut être rapporté par encliquetage, soudage ou autrement sur la partie d'épaulement d'un tube souple soit en aluminium, soit en matière plastique ; il peut également être venu de moulage avec un emballage distributeur compressible ou non. Par ailleurs, l'ajutage au lieu d'être fileté pourrait comporter un embout de forme quelconque adapté à coopérer avec un capuchon défonceur approprié.The invention is, of course, not limited to the details of the embodiments described by way of examples, but on the contrary lends itself to various methods of implementation. Thus, for example, the nozzle can be added by snap-fastening, welding or otherwise on the shoulder part of a flexible tube, either of aluminum or of plastic material; it may also have come from molding with a compressible or non-compressible dispenser packaging. Furthermore, the nozzle instead of being threaded could include a nozzle of any shape adapted to cooperate with an appropriate knockout cap.

En omettant de disposer des boutons de verrouillage sur certains des secteurs de l'opercule, on permet à ces secteurs de reprendre leur position initiale après défonçage ; on obtient alors une section d'écoulement différente qui peut être désirable dans certaines applications.By omitting to have locking buttons on some of the sectors of the cover, these sectors are allowed to return to their initial position after knocking down; a different flow section is then obtained which may be desirable in certain applications.
