Problems solved by technology

[0005] The disadvantage of this known solution is that the structural design of the relevant end of the receptacle is expensive
In extrusion devices of the type described, the forces acting on the interface of the extrusion device are high, so that after a certain service life this can lead to gaps between the extrusion unit and the receiving unit

Embodiment Construction

[0022] In principle, identical parts are provided with the same reference symbols in the various figures.

[0023] exist Figures 1 to 3 The extrusion device 11 shown in has an extrusion unit 12 and a receiving unit 32 with a receptacle 34 for a container 33 . The container 33 is a multi-chamber cartridge having two side-by-side tubular containing bodies for directly or indirectly containing extrudable material, which is packaged in a film bag for use by the user. The ejection unit 12 comprises an advancing mechanism with two piston rods 13, on whose free ends pressure plates are arranged. The advancing mechanism is actuated via a manually actuatable lever 14 next to the handle 15 and advances the piston rod 13 in the direction of the receiving unit 32 by a distance determined by the advancing mechanism.

[0024] The receptacle 34 of the receptacle unit 32 is bounded at one end 36 by a head piece 35 and has an end 37 remote from the head piece 35 . The head piece 35 has an ...

Abstract

An ejection device (11) has an ejection unit (12) having a displacement mechanism with two piston rods (13), a receptacle unit (32) including receptacle (34) for a container (33), a head part for limiting the receptacle (34) at one of its ends, a holding device (21) which is arranged on the ejection unit (12) for securing the receptacle unit (32) thereto, and tension members (38) provided on the receptacle unit (32) and which extend along the receptacle (34) and are secured to the head part (35), each tension member (38) having a engageable-from behind section (39) at its end remote of the head part, the holding device (21) having locking elements which can engage the engageable-from behind sections (39) of the tension members (38) to lock the receptacle unit (32) with the ejection unit (12).

Description

technical field [0001] The invention relates to an extrusion device, which has an extrusion unit with an advancing mechanism with at least one piston rod, and a receiving unit with a drive unit for a device that can be moved by means of the at least one piston rod. Receptacle for extruded containers, wherein the receptacle is bounded at one end by a head piece and has an end remote from the head piece, and wherein the receptacle unit is releasably detachable by means of a holding device arranged on the extrusion unit fixed on the extrusion unit. Background technique [0002] An ejection device of this type is used to remove material packed in containers, for example film bags or tubes, such as mortar material or sealing material, at an application site. By operating the propulsion mechanism, the at least one piston is pushed forward a predetermined distance, wherein a pressure plate arranged on the piston rod acts on the container and takes out a corresponding amount of the...
