An apparatus for applying viscous material to workpieces has at least two material outlets. A needle valve is assigned to each material outlet, the valve needle of which being able to close the respective material outlet on a valve seat. Each valve needle is assigned a cylinder, in the piston chamber of which a piston is movable by pressure applied by a fluid, and which cylinder has a piston rod for impingement on the respective valve needle, the piston rod being connected to the piston, being guided out of the piston chamber on an end face facing the valve seats and extending longitudinally. The cylinders are arranged one behind the other longitudinally and the piston rod of at least one of the cylinders is guided in a sealed manner through the piston chamber of at least one further cylinder arranged closer on the valve seats.

Caulking systems and caulking system accessories are described herein.

A caulking gun handle and a caulking gun are provided. A caulking amount adjusting assembly is mounted on a movable handle of the caulking gun; the caulking amount adjusting assembly comprises a driving shaft and a driving shaft positioning member; portions at two sides of a mounting groove are each formed as a handle mounting portion; a driving protrusion and first and second positioning recesses are provided on a peripheral surface of the driving shaft, the driving shaft can slide left and right with respect to the two handle mounting portions, so that in a first workstation, an end portion of the driving shaft positioning member located in the driving shaft mounting hole is engaged in the first positioning recess, and in a second workstation, the end portion of the driving shaft positioning member located in the driving shaft mounting hole is engaged in the second positioning recess.

A head part for a cartridge is provided for interacting with a dispensing device. The head part has a first receiving region for interacting with a first container and a second receiving region for interacting with a second container. The first receiving region is connected to a first channel and the second receiving region is connected to a second channel which is separated from the first channel at least in regions. A control device is arranged in at least one of the channels for controlling a volume flow of a composition guided through the corresponding channel. A cartridge for a dispensing device has such a head part.

The invention comprises a dispensing device having an elongated body, a sidewall which is elliptical in at least a portion of its cross-section, an open top end, and a dispensing bottom end. The device comprises a ratchet, ratchet support member, dial, telescoping members, and an elliptical plunger. The ratchet support member and dial each engage the ratchet to allow movement in certain directions and prevent movement in other directions, beyond a certain point. A first telescoping member is affixed to the ratchet. The exterior diameter of a second telescoping member is smaller than the interior diameter of the first telescoping member, such that the second telescoping member is configured to nest within the interior of the first telescoping member. The second telescoping member may be extended a distance through the dispenser body via rotation of the ratchet. The plunger is affixed to the telescoping member having the smallest diameter.

This invention is a gun shaped device used in the application of caulk, paste and or other semi solid high viscosity fluids. The device contains a barrel portion for the tube to be inserted into, and a plunger portion with a flat round metal piece with a fitting that attaches to a set of shortened rods. The set of shortened rods acts as a plunger and goes through a guide toward the back of the handle. The barrel can be shortened for use of smaller tubes of caulk.

A dispensing nozzle for viscous material having a modified outlet is disclosed herein. The dispensing nozzle includes a first terminal portion, a second terminal portion, and a medial portion defined therebetween. The first terminal portion includes an attachment region configured to secure the dispensing nozzle to a dispensing gun. The second terminal portion includes a dispensing tip defining the outlet for the viscous material. The outlet has a quadrilateral profile in one embodiment. In another embodiment, the outlet has a square profile.

An applicator is proposed comprising an outer sleeve having a cylindrical inner surface and a receiving space for a flowable substance to be applied and an inner sleeve which can be displaced in the outer sleeve and in which a frangible ampule containing the flowable substance is disposed and which has an opening connecting an interior of the inner sleeve to the receiving space of the outer sleeve and an activation means upon whose activation the ampule breaks.

A mixing tip for mixing multi-component materials exiting a multi-component cartridge includes a code that is stored in or at the mixing tip indicating at least one of a type of mixing tip, a manufacturer of the mixing tip, a date of production of the mixing tip and a list of materials compliant with the mixing tip.
