An improved dispensing device for application and dispensing of viscous liquid substances comprising of a storage reservoir, dosing mechanism with audible and tactile feedback, dispensing plunger, nozzle tip, and end of travel pressure release mechanism. The dosing and the dispensing are de-coupled, allowing a preselection of dosage volume and controlled dispensing. A pressure relief mechanism is incorporated to eliminate oozing of liquids after the termination of dispensing.

A power operated dispensing tool includes a housing having a material packing receiving space, and a rod disposed within and movable relative to the housing and having a plunger head that is disposed in the material packing receiving space. The rod is operably coupled to a power transmitting mechanism so as to make a forward movement driven by a power of a motor through the power transmitting mechanism to discharge a dispensing material in the material packing receiving space. The rod has an initiating portion disposed to actuate a sensing member in the housing to deactivate the motor when the rod is moved forwardly to a first stop position. The rod can be moved manually to a second stop position to project the plunger head outwardly so as to permit a plunger kit to be attached thereto.

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 dispenser including a sub-assembly to engage and disengage a plunger rod. The sub-assembly minimizes the need for springs and other biasing members within the dispenser.

A liquid compound dispensing apparatus for dispensing a controlled amount of liquid compound onto a workpiece is described. The apparatus comprises a cartridge system. The cartridge system may accept a liquid compound cartridge containing liquid compound. The apparatus also comprises a plate, having a threaded bore, positioned above the cartridge system that is movable in a first and second direction, at least one plunger attached to the plate at a first end and attached to a piston at a second end. The piston is dimensioned to move within the liquid compound cartridge to displace liquid compound when the plate is moved in the second direction. A driving mechanism moves the plate in the first and the second directions to dispense product and comprises a motor, a threaded rod disposed through the threaded bore of the plate that is driven by a driving belt attached to the motor.

A dispensing device includes a drive unit, a detector and a controller. The drive unit is configured to operate a material dispenser. The detector is configured to detect a velocity of the material sensor. The controller is programmed to maintain the material dispenser at a constant velocity based on the velocity detected by the detector.

The invention relates to a twist-action, portion-control dispenser having a dispenser body, a grip ring attached to an exterior surface of the dispenser body, and a piston movably fitted within the dispenser body and coupled to the grip ring. The piston is configured to move incrementally downwards through the dispenser body when the grip ring is rotated relative to the dispenser body. A sauce pouch is contained within the dispenser body, in contact with the piston, such that sauce is dispensed from the dispenser as the piston is moved incrementally downwards.

A dispensing apparatus for a flowable component includes a storage container having a storage chamber for the reception of the component, a filling opening and a dispensing opening. A piston is displaceably arranged within the storage container in the direction of an expulsion direction. Moreover, dispensing apparatus includes an actuation element by which the piston can be displaced stepwise in the direction of the dispensing opening. After release of the actuation element actuation element is displaced from a final position into a starting position by a spring.
