L'invention est relative aux capsules de fermeture de conteneur, en matière plastique. Elle concerne plus particulièrement la capsule elle-même, seule ou associée à un conteneur, un procédé de fabrication de telles capsules et, enfin un dispositif pour la mise en oeuvre du procédé. Les capsules (1) visées sont celles classiquement appelées "capsules-service" et du type comprenant :
une partie de base (3) essentiellement rigide dans son ensemble, incluant une paroi latérale périphérique (8), une paroi transversale (12) et ayant un orifice (15) excentré ; et une partie de fermeture (4) et de manoeuvre de commande, essentiellement rigide dans son ensemble, agencée pour pouvoir être montée de façon mobile à pivotement sur la partie de base (3), dans un sens ou dans l'autre et ouvrir ou fermer, respectivement, la communication avec l'orifice (15).
摘要:
The process for manufacturing a container made of glass comprises a step of shaping a parison by means of a mould at least one surface of which is coated with a lubricant at the interface between said parison and said surface of the mould. According to the invention, the lubricant is a solid lubricant made of tungsten disulphide.
摘要:
The invention relates to a stopcock for a container neck, comprising valve means with a pushbutton (1) suitable for being moved between open and closed positions of a liquid delivery passage. Said valve means comprises, further to said pushbutton (1), a seating member (3) provided with a mouth, adapted to be attached to said neck. Between said seating member (3) and said pushbutton (1) there is defined an interstitial space (5) wherein there is housed a resilient member (6) ensuring the return of the pushbutton (1) to the closed position thereof, at the same time as it ensures the opening and closing of the liquid delivery passage thanks to ports and to hermetic stoppering means of said interstitial space (5).
