Problems solved by technology

[0005] The disadvantage of compressing one of the outlets of the blow molded part is that the flow cross-section of the outlet is reduced and must be opened and enlarged only by ejecting the components

Embodiment Construction

[0014] figure 1 The illustrated multicomponent cartridge 1 according to the invention is of tubular design. Its front end in the figure has an orifice-shaped end wall 2 with a tubular outlet 3 provided with an external thread 4 . The multicomponent cartridge 1 forms an outer container 5 into which an inner container 6 is inserted. The inner container 6 is a blow molded part. The two containers 5 , 6 each contain a component of a two-component substance, for example a glue and a hardener, which are stored separately from one another in the cartridge 1 . Thus in the illustrated and described embodiment the multi-component cartridge 1 is a two-component cartridge. In order to eject these components, the inner container 6 can be compressed axially. By means of a piston (not shown) of a spray gun (not shown), the components, which harden after mixing, can be sprayed out of the outlet 3 of the cartridge 1 . The cross-sections of the containers 5, 6 are constant along the longit...

Abstract

The invention relates to a multi-component cartridge for jointly dispensing a plurality of components which are stored separately from one another in the multi-component cartridge (1), having a tubular outlet (3), in which a tubular inner outlet (8) is located, and having a closure component (9), which can be screwed onto the outlet (3) and by means of which the outlets (3, 8) can be closed. In order to create such a cartridge which does not compress the outlets of the components upon closure, the application proposes that the closure component (9) has an intercepting helix (12) which has theinner outlet (8) coming into abutment against its inside when the closure component (9) is screwed onto the outlet (3) and which centres the inner outlet (8) in the intercepting helix (12) as the screwing-on action continues.

Description

technical field [0001] The present invention relates to a multi-component cartridge. Background technique [0002] A two-component cartridge is known from DE 103 10 162 A1. It is tubular and contains two blow-molded parts as containers, in which two flowable components of a substance are contained separately from one another. The blow molded parts extend with the same cross-section in the longitudinal direction of the cartridge, each of which occupies part of the cross-section of the cartridge. Blow molded parts can be compressed so that the cartridge and the contents contained in the cartridge can be ejected from the piston of a spray gun or similar spray device. [0003] After spraying, the two components enter, for example, a static mixer mounted on the two-component cartridge, which mixes the components. The mixed ingredients harden. These components may, for example, be binders or hardeners. Even though the invention has been described with the aid of a two-compone...
