A CARTRIDGE FOR A FLEXIBLE PACKAGE AND A DRIVE MEANS FOR EMPTYING A CARTRIDGE

摘要

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).
