Abstract
Description
La présente invention concerne une capsule métallique de bouchage du type "couronne", c' est-à-dire une capsule en métal emboutie dont le fond est raccordé à une courte jupe extérieure par un coude arrondi dont le bord est serti sous la bague du récipient. The present invention relates to a metal closure cap of the "crown" type, that is to say a stamped metal capsule, the bottom of which is connected to a short outer skirt by a rounded elbow, the edge of which is crimped under the ring of the container.
Elle a pour but de réaliser une capsule qui nécessite moins de métal, un joint plus mince et assure une meilleure étanchéité. Its purpose is to produce a capsule which requires less metal, a thinner seal and provides better sealing.
A cet effet le raccordement du fond et de la jupe de la capsule présente avant sertissage un profil parallèle à celui de la bague du col du récipient; ltélément nouveau de cette capsule est le fait'que, pour envelopper le maximum et avec le maximum de régularité la bague ou rebord de la bouteille ou récipient à boucher, la capsule avant sertissage présente un profil parallèle à celui de cette bague depuis son bord intérieur jusque sous le bord extérieur inférieur de la bague. For this purpose the connection of the bottom and the skirt of the capsule present before crimping a profile parallel to that of the ring of the neck of the container; the new element of this capsule is the fact that, to envelop the maximum and with the maximum regularity the ring or rim of the bottle or corking container, the capsule before crimping has a profile parallel to that of this ring from its inner edge up to the lower outer edge of the ring.
le fond de la capsule est préférablement embouti pour présenter une cuvette concave vers l'extérieur du récipient et être renforcé par un nervurage pour résister à la pression du contenu du récipient. the bottom of the capsule is preferably stamped to present a concave bowl towards the outside of the container and to be reinforced by ribbing to resist the pressure of the contents of the container.
Le galbe du bouchon étant fait pour entre exactement parallèle àcelui du col de la bouteille, l'étanchéité est améliorée, mais pas au point de rendre inutile le joint qui se trouve cependant très diminué. The curve of the cap being made to enter exactly parallel to that of the neck of the bottle, the seal is improved, but not to the point of rendering the seal useless, which however is greatly reduced.
La capsule comporte le même joint qu'habituellement, mais en épaisseur très inférieure. The capsule has the same seal as usual, but in much smaller thickness.
De même, la forme de cette capsule épousant davantage la forme de la bouteille, il est évident qu'il y a une économie de métal. Likewise, the shape of this capsule more closely matching the shape of the bottle, it is obvious that there is a saving of metal.
Ce perfectionnement apporté aux capsules du type couronne est illustré sur le dessin ci-annexé sur lequel
la figure 1 est une vue en élévation, partie en coupe d'une capsule modifiée suivant l'invention.This improvement made to crown type capsules is illustrated in the attached drawing in which
Figure 1 is an elevational view, partly in section of a capsule modified according to the invention.
La figure 2 est une vue en plan correspondante. Figure 2 is a corresponding plan view.
La figure 3 est une vue analogue à la figure 1 montrant la capsule sertie sur le col du récipient. Figure 3 is a view similar to Figure 1 showing the capsule crimped on the neck of the container.
Cette capsule est obtenue de façonclassique par emboutissage d'une feuille de métal, mais elle diffère des capsules connues par le fait que le raccordement du fond 1 et de la jupe externe 3 présente avant sertissage un galbe 7 parallèle au profil de la bague 5 de la bouteille 6, prise comme exemple de récipient à
boucher; de préférence le fond 1 présente un embouti central en forme de cuvette 2 concave vers ltextérieur. This capsule is obtained in a conventional manner by stamping a sheet of metal, but it differs from known capsules in that the connection of the bottom 1 and the external skirt 3 has, before crimping, a curve 7 parallel to the profile of the ring 5 of bottle 6, taken as an example of a container for
butcher; preferably the bottom 1 has a central deep-drawn dish 2 concave inward.
De la sorte il y a après sertissage un contact étroit entre la bague 5 et le galbe 7 de la capsule depuis le bord 4 de la cuvette 2 jusqu' au bord de la jupe externe 3. In this way, after crimping, there is a close contact between the ring 5 and the curve 7 of the capsule from the edge 4 of the bowl 2 to the edge of the outer skirt 3.
la cuvette 2 peut entre nervurée pour renforcer le fond de la capsule qui, du fait du galbe arrondi permet une économie de métal par rapport à une capsule standard. the bowl 2 can between ribbed to reinforce the bottom of the capsule which, due to the rounded curve allows a saving of metal compared to a standard capsule.
Un joint mince 8 peut être inséré dans le fond de la capsule pour parfaire l'étanchéité, mais il peut être réduit à une pellicule. A thin seal 8 can be inserted into the bottom of the capsule to complete the seal, but it can be reduced to a film.
L'essentiel de l'invention est d'enrober sans jeu ni solution de continuité tout le contour de la bague 5 du récipient par un embouti 7 de profil exactement parallèle , avant sertissage, à celui de la bague ou reMord du récipient à boucher : du fait de la surface de contact du bord de la capsule et du bord du récipient qui est notablement plus étendue que dans les capsules courantes, on obtient une augmentation de l'étanchéité de retenue de la pression interne du récipient. The essence of the invention is to coat without play or solution of continuity the entire contour of the ring 5 of the container by a stamped 7 of profile exactly parallel, before crimping, to that of the ring or reMord of the container to be capped: because of the contact surface of the edge of the capsule and of the edge of the container which is considerably more extensive than in current capsules, an increase in the tightness retaining the internal pressure of the container is obtained.
