CA 2321549

A cartridge (2) for a flexible package (1) consists substantially of a housing (3) and a piston (5) arranged displaceably along an axis (A) within the housing. The piston comprises projections (11) which extend outwardly of the piston and through slits (10) in a body portion (6) of the housing (3) of the cartridge (2). The piston (5) may be displaced along the axis (A) of the cartridge (2) by action of force on the projections (11) which extend outwardly of the cartridge (2). The projections may be engaged with external drive means. The external drive means (21) comprise screw means (22) which are engageable with the projections and which are used to displace the piston. Upon displacement of the piston (5), the content within the package (1) is compressed and dispensed through the dispensing opening (4) of the cartridge (2).

La présente invention concerne une enveloppe (2) conçue pour un conditionnement flexible (1) constituée de manière générale par une enceinte (3) et un piston (5) disposé dans l'enceinte de façon amovible le long d'un axe (A). Ce piston comprend des saillies (11) s'étendant de l'extérieur et à travers des fentes (10) situées dans la partie corps (6) de l'enceinte de l'enveloppe (2). Le piston se déplace le long de l'axe (A) de l'enveloppe (2) sous l'action d'une force s'exerçant sur les saillies (11) qui s'étendent à l'extérieur de l'enveloppe (2). Ces saillies peuvent venir en prise avec un dispositif de commande externe. Ce dispositif de commande externe (21) comprend des ressorts venant en prise avec les saillies et servant à déplacer le piston. Lorsque le piston (5) se déplace, le contenu du conditionnement (1) est comprimé puis distribué à travers l'ouverture de distribution (4) de l'enveloppe (2).
