A dispenser for mixing and dispensing a multi-component adhesive or sealant includes a first motor operably coupled to two or more plungers, each plunger being slidably disposed in a respective one of two or more barrels and configured to apply a dispensing pressure to respective materials to be dispensed, a second motor operably coupled to an output drive shaft having a mating end, and a coupling plate removably attached to a front end of the dispenser, the coupling plate configured to attach to a disposable mixer attachment configured to mix and dispense the multi-component adhesive or sealant, the disposable mixer attachment having a drive shaft driving a mixing component and configured to selectively couple with the mating end of the output drive shaft of the second motor, thereby enabling dynamic mixing of the respective materials to be dispensed.

A cartridge has a reception chamber extending in a longitudinal direction for a medium to be dispensed. The cartridge has a head part and a cartridge wall which bound the reception chamber, the head part having an outlet for the medium. The cartridge wall is at least regionally a film and the head part is a stable-shape part. The head part is sealingly and in particular unreleasably connected to the cartridge wall and the cartridge is a collapsible cartridge. The cartridge can be converted from an expanded state in which the reception chamber has a maximum volume into a collapsed state in which the reception chamber has a minimal volume. The cartridge not yet filled with medium is in a collapsed state. Furthermore, a method of manufacturing such a cartridge is described.

A system and method for filling joints in concrete. The system includes an A-side joint filler compound portion, a B-side joint filler compound portion, and a liquid pigment portion, which are mixed together in a mixing container initially containing only the A-side joint filler compound portion. The portions are mixed using a mixing rod. An elongate nozzle is then attached to the mixing container, and the mixing container added to an application gun for application to the joint.

A dispensing apparatus includes two cylindrical sleeves, two flexible film pack bags disposed within the sleeves, the two film pack bags having an integrally formed rigid face plate bonded therewith, the face plate having a discharge nosepiece integrally formed therewith, the discharge nosepiece having a partition internally configured to maintain separate flow streams from the film pack bags. Two shuttles are slidingly disposed in the sleeves. Push rods are disposed in operable communication with the shuttles. At least one piston is disposed in operable communication with the push rods, the piston configured to drive the push rods. A holder is disposed proximate a front end of the sleeves, the holder configured to restrain the face plate during dispensing of a flowable material. A mixer is configured to be in fluid communication with flow streams from the film pack bags. A material applicator is disposed in fluid communication with the mixer.

A pastry bag includes: a container containing a creamy substance; a nozzle connected to the container; and an auxiliary member. The auxiliary member includes: a fixing portion fixed to the nozzle; and a positioning portion to be brought into contact with a creation surface on which a decoration is to be created.

A storage container for a cylindrical tube of viscous construction material includes a body dimensioned to receive a cylindrical tube of viscous construction material. A nozzle enclosure is attached to a top end of the body and is dimensioned to receive a nozzle of a cylindrical tube of viscous construction material. A plug is positioned in the nozzle enclosure and dimensioned to fit into an inner diameter of the nozzle of the cylindrical tube of viscous construction material. A gasket is positioned between the body and the nozzle that substantially prevents air in the body from entering into the nozzle enclosure. A base seals the cylindrical tube of viscous construction material in the body.

A kit for converting a gun-type sauce dispenser to dispense flowable materials such as sauces from flexible-walled containers comprises a nose piece, a dispensing tube and a supplemental piston. The nose piece has a forward end adapted to be attached to an end stop of the sauce dispenser. An opening extends axially through the nose piece. The nosepiece is adapted to be coupled to the dispensing tube such that the dispensing tube is held axially relative to the nose piece. A top sheet of a flexible-walled container may be retained between the nose piece and the dispensing tube. The nose piece may comprise a member arranged to tension the end sheet of the container.

A foil cartridge fillable with at least one fluid includes a foil bag as a cartridge shell and a rigid head part. The head part includes an outlet opening for emptying the fluid of the foil cartridge and an external thread for fastening the foil cartridge to a support sleeve. The foil bag is fixed to the head part in the region of the external thread.

An application device (1) for applying a viscous material onto a substrate and a method for producing the application device (1). The application device (1) includes a ventilation device having an insert (19), which is connected air-tightly to an inner container (3) in the region of a discharge opening (18). An annular gap is formed between the insert (19) and a neck region (6) of the outer casing (2), through which annular gap air can flow from outside into an intermediate space between the outer casing (2) and the inner container (3) and vice versa. The connection between an applicator (4) and the outer casing (2) is also permeable to air and the applicator (4) includes a sealing means (25) that seals off the inner volume of the inner container (3) in an air-tight and leak-proof manner from the intermediate space.

A dispenser for dispensing a mixing of viscous materials is provided, to dispense a two or more component material such as a two or more component sealant or adhesive. The dispenser comprises a dispensing mechanism for dispensing respective materials from a material holder through a dynamic mixer. The dispensing mechanism is driven by a first electric motor and the dynamic mixer is driven by a second electric motor. Advantageously, a simple and effective multicomponent dispenser with a dynamic mixer is provided.
