Title
(EN) CARTRIDGE, DISPENSING ASSEMBLY AND METHOD OF MANUFACTURING A CARTRIDGE
(FR) CARTOUCHE, ENSEMBLE DE DISTRIBUTION ET PROCÉDÉ DE FABRICATION D'UNE CARTOUCHE
Abstract
(EN)
The invention relates to a cartridge for a medium to be dispensed comprising a rigid head part (6) having a dispensing outlet (12) and a flexible film forming a cartridge wall (5). The film bounds a cartridge chamber (2) for the medium to be dispensed and extends at least partially in a longitudinal direction of the cartridge. The head part comprises a collar (17) surrounding the dispensing outlet in a radially outer region of the head part, wherein the collar extends in the longitudinal direction and has an inner circumferential surface. A front end of the film is sealingly and non-releasably connected to the inner circumferential surface of the collar. The invention is characterized by the attachment of the film to the inner circumferential surface of the head part at a contact surface that is different from the outer surface of the film. The invention further relates to a dispensing assembly and to a method of manufacturing such a cartridge.
(FR)
L'invention concerne une cartouche pour une matière à distribuer, laquelle cartouche comprend une partie tête rigide (6) pourvue d'une sortie de distribution (12) et un film souple formant une paroi de cartouche (5). Le film délimite une chambre de cartouche (2) destinée à contenir la matière à distribuer et s'étend au moins partiellement dans une direction longitudinale de la cartouche. La partie tête comprend une collerette (17) entourant la sortie de distribution dans une région radialement externe de la partie tête, cette collerette s'étendant dans la direction longitudinale et présentant une surface circonférentielle interne. Une extrémité avant du film est reliée de manière étanche et non séparable à la surface circonférentielle interne de la collerette. L'invention est caractérisée en ce que le film est fixé sur la surface circonférentielle interne de la partie tête au niveau d'une surface de contact qui est différente de la surface externe du film. L'invention concerne en outre un ensemble de distribution et un procédé de fabrication d'une telle cartouche.
