A two-component piston for a cartridge includes a piston cover and a piston body. The piston cover has a radially extending attachment portion, a rear side and a front side. The piston body includes a front side and a rear side. The rear side of the piston cover is arranged adjacent to at least a part of the front side of the piston body and includes a valve member configured and arranged to be received within the piston body and to extend into the piston body towards the rear side of the piston body. The piston cover moves relative to the piston body upon actuation of the valve member, and the piston cover is non-releasably connected to the piston body by a part of the piston body being overmolded to the radially extending portion of the attachment portion of the piston cover.

Piston, cartridge and method of venting a cartridge

A method of making a two-component piston, the two-component piston including a piston cover as the first component and a piston body as the second component. The piston cover is arranged adjacent to the piston body and is configured to be moved relative to the piston body.

Two-component piston for a cartridge, and a cartridge

A cartridge for a material to be dispensed includes a rigid head part having a dispensing outlet and a flexible film forming a cartridge wall, with the flexible film bounding a cartridge chamber for the material to be dispensed, extending at least partially in a longitudinal direction of the cartridge and having a front end that is connected to the head part. The head part has an outer circumferential surface, and an inner surface of the front end of the flexible film is sealingly and non-releasably connected to the outer circumferential surface of the head part.

Cartridge, method of manufacturing a cartridge, dispensing assembly and method of assembling a dispensing assembly

A cartridge for a medium to be dispensed includes a rigid head part having a dispensing outlet and a flexible film forming a cartridge wall. The film bounds a cartridge chamber for the medium and extends partially in a longitudinal direction of the cartridge. The head part includes a collar surrounding the dispensing outlet in a radially outer region of the head part, and 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. Attachment of the film to the inner circumferential surface of the head part is at a contact surface that is different from the outer surface of the film.

Method of making a two-component piston

A two-component piston for a cartridge includes a piston cover as the first component and a piston body as the second component. The piston has a first side and a second side, and a rear side of the piston cover arranged adjacent to at least a part of the piston body. A front side of the piston cover is arranged at the first side, and the rear side of the piston cover includes a valve member. The valve member is to be received within the piston body and to extend into the piston body towards the second side. The piston cover is configured to be moved relative to the piston body on actuation of the valve member and the piston cover is non-releasably connected to the piston body.

The head part has a collar, the collar surrounding the dispensing outlet in a radially outer region of the head part and extending in the longitudinal direction. The front end of the film is sealingly and non-releasably connected to the collar of the head part. The collar of the head part has an inner surface extending in the longitudinal direction and includes at least one projection projecting radially inwardly.
