Title
(EN) A SELF-RESEALING MAGNET CLOSURE
(FR) FERMETURE À AIMANT AUTO-REFERMABLE
Abstract
(EN)
A syringe for dispensing a flowable material. The syringe has a cartridge with a cartridge front end and at least a first dispensing nozzle arranged at the cartridge front end. The syringe further has closure for openably closing the first dispensing nozzle. The closure includes a cap and at least a first seal. The cap is telescopically placeable on the cartridge front end. The closure or the cartridge has a first magnet for establishing a magnetic attraction between the closure and the cartridge. In a situation in which the closure is placed on the cartridge front end, the closure and the cartridge can be positioned in a sealing position in which the first seal spaces the cap and the cartridge front end away from each other against a magnetic attraction that urges the cap and the cartridge toward each other.

La présente invention concerne une seringue destinée à distribuer une matière pouvant s'écouler. La seringue a une cartouche ayant une extrémité avant de cartouche et au moins une première buse de distribution disposée au niveau de l'extrémité avant de cartouche. La seringue comprend en outre une fermeture pour fermer de manière ré-ouvrable la première buse de distribution. La fermeture comprend un capuchon et au moins un premier joint d'étanchéité. Le capuchon peut être placé de manière télescopique sur l'extrémité avant de cartouche. La fermeture ou la cartouche a un premier aimant pour créer une attraction magnétique entre la fermeture et la cartouche. Dans une situation dans laquelle la fermeture est placée sur l'extrémité avant de cartouche, la fermeture et la cartouche peuvent être positionnées dans une position d'étanchéité dans laquelle le premier joint d'étanchéité écarte le capuchon et l'extrémité avant de cartouche l'un de l'autre contre une attraction magnétique qui pousse le capuchon et la cartouche l'un vers l'autre.
