A piston for dispensing a flowable component from a cartridge includes a piston having a base body and a venting element. The base body has a passage connecting a component side and an actuation side and has a passage opening. The venting element has an internal connection element and a pin which is partly arranged in the passage opening of the base body. The internal connection element and the pin are connected by a spring element. The pin of the venting element can adopt a sealing position and an aerating position. To enable a secure sealing, the spring element is configured such that it includes an angle of a maximum of 80 with the axial direction in the sealing position of the pin at a connection line to the internal connection element in the direction of an actuation side.

A cartridge for a one or two-component mixing and dispensing system includes at least one flexible film bag as a cartridge wall, a rigid front part that is in particular integrally formed with the at least one flexible film bag and that is arranged at a front end section of the at least one film bag, the rigid front part including at least one outlet opening. The cartridge for a two-component mixing and dispensing system has a first flexible film bag as a cartridge wall and a second flexible film bag as a cartridge wall, and a structure surrounding the cartridge.

An adapter couples to a single component fluid dispenser. The adapter includes a cap section, a first outlet, a second outlet, and a coupling member. The cap section has a cap interior surface that defines a cap channel extending therethrough. The first outlet defines a first outlet channel extending therethrough that is in fluid communication with the cap channel. The second outlet defines a second outlet channel extending therethrough that is in fluid communication with the cap channel. The coupling member is configured to couple the adapter to a nozzle.

A device for applying a mixed component, includes first and second receptacles, a static mixing nozzle, an applicator and an operating member. The first and second receptacles are to receive first and second components, respectively. The static mixing nozzle includes a plurality of mixing elements, has a first end and a second end, and is in fluid communication with the first and second receptacles. The applicator includes a spray tip and an input for pressurized fluid, the spray tip disposed downstream of the second end of the static mixing nozzle and in fluid communication with the static mixing nozzle. The operating member is configured to control the pressurized fluid.

A cartridge for a medium to be dispensed is disclosed. The cartridge includes a head part having a dispensing outlet, and a film forming a cartridge wall. The film bounds a cartridge chamber for the medium to be dispensed, and extends at least partially in a longitudinal direction of the cartridge. The film has a front end that is connected to the head part. The is a multilayer film having at least two layers formed from different materials. The front end of the film is sealingly and non-releasably embedded in the head part of the cartridge, such that an end face of the front end of the film is covered by the head part. A method of manufacturing a cartridge having a head part using a mold is also disclosed.

Varied embodiments of a container/dispenser having a multi-chamber bellows member having a plurality of collapsible bellows chambers allowing more than one substance to be contained within the container and simultaneously dispensed when a sufficient axial force is exerted on a platform to compress the bellows member forcing flowable materials from each chamber. In an alternative embodiment, the present invention discloses a retrofit multi-chambered bellows container, which may be adapted to a standard caulking tube container.

A device for applying a mixed component includes first and second receptacles configured to receive first and second components, respectively, a static mixing nozzle, an applicator and an operating member. The static mixing nozzle includes a plurality of mixing elements, has a first end and a second end, and is in fluid communication with the first and second receptacles. The applicator includes a spray tip and an input for pressurized fluid, the spray tip is disposed downstream of the second end of the static mixing nozzle and is in fluid communication with the static mixing nozzle. The operating member is disposed on the applicator and is configured to control the pressurized fluid.

A metering and mixing device contains a multichamber cartridge and a cartridge holder having a reception container for the multichamber cartridge and a compressed air connection and a connection for an application device. The reception container has an internal tube arranged coaxially to the walls of the cartridge holder and equipped with static mixing elements. The multichamber cartridge contains an upper portion having a directional valve, a middle portion configured as a tubular empty space surrounded by at least two chambers arranged tubularly in the direction of the longitudinal axis of the cartridge, and a lower portion having a piston for each chamber. The multichamber cartridge is arranged in the cartridge holder such that the inner wall of the inner tube of the multichamber cartridge bears, leak-tight, against the outer wall of the tube of the cartridge holder.

A delivery system is provided that includes a device having a body extending along a longitudinal axis between proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extends through the wall and includes a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a fluid within the proximal chamber out of the first port and the distal plunger moves a fluid within the distal chamber out of the second port to simultaneously actuate a bone filler dispenser. Systems and methods are also provided.
