Problems solved by technology

When the pressure on the piston is released, the pressure on the multi-component material stored in the cartridge is not always released immediately, which may undesirably also cause other multi-component material to be removed from the cartridge via the outlet passage and dispensed, and Contamination in exit pathway
Furthermore, when dispensing material from a cartridge, the less viscous component of the two components can leave the cartridge first and lead to a departure ratio between the components to be dispensed, so that and thus due to too high a proportion Mixing low viscosity material with high viscosity material reduces mix quality, which is highly undesirable
[0007] This is undesirable as contamination in the outlet passage could lead to degradation of the material stored in the multi-component cartridge

Embodiment Construction

[0060] figure 1 Cartridge 1 is shown, which is designed as a two-component cartridge. The cartridge 1 comprises two substantially cylindrical cartridge chambers 2 , 3 . The cartridge chambers 2 , 3 are each delimited by a cartridge wall 4 , 5 and by a head portion 6 , 7 , wherein each head portion 6 , 7 is arranged at a respective front end 8 , 9 of the cartridge wall 4 , 5 . Each cartridge wall 4 , 5 extends in the longitudinal direction A of the cartridge 1 from a respective rear end 10 , 11 to a respective front end 8 , 9 .

[0061] Each head portion 6, 7 is a stable shaped portion having a generally plate-like shape and comprises a respective dispensing outlet 12, 13 with an outlet opening 12', 13' via which access can be made from the cartridge chamber 2, 3 Dispense the corresponding medium (not shown). The two dispensing outlets 12 , 13 extend as outlet passages 14 , 15 from the head parts 6 , 7 through a common outlet 16 . A mixing tip or closure member (each not sh...

Abstract

The present invention relates to a cartridge for an adhesive or a coating, the cartridge comprising a head part (6) having an outlet (12, 13), the head part being integrally formed with a cartridge wall (41, 5'), wherein the outlet has one, two or more outlet passages (20) formed therein, wherein a valve (19) is provided in each one of the one, two or more outlet passages, with the valve being axially and radially fixed in position relative to the head part at a peripheral portion of the valve.

Description

technical field [0001] The present invention relates to a cartridge for adhesive or paint, said cartridge comprising a head portion with an outlet, wherein one, two or more outlet passages are formed in said outlet, wherein a valve is arranged at In each of the one, two or more outlet passages. The invention further relates to a method of making such a cartridge, and a method of using such a cartridge. Background technique [0002] Multi-component materials are dispensed using cartridges, especially two-component cartridges. This multi-component material is used in a variety of applications, from industrial applications such as bonding structural parts to each other using adhesives, or as coatings for buildings or vehicles, to medical and dental applications. The multi-component material is, for example, a two-component adhesive comprising a filler material and a hardener. Multi-component cartridges are available in various fill ratios (also referred to as mix ratios), fo...
