- Discharging be intimately mixed by means of a dynamic or a static mixing device.
- examples include two-component adhesive or chemical dowels, which only after mixing the two
- Harden components are also used for paints, which are often used for the production of functional protective coatings, eg for corrosion protection.
- the cartridges comprise one or more axially displaceable delivery pistons, by whose movement the material is discharged from the chamber or the chambers.
- the chambers must have sufficiently thick walls in order to withstand the pressure arising during discharge can.
- the cartridges must have sufficiently thick walls to be sufficiently diffusion-tight. This is particularly important in terms of storage, to diffuse in or out diffusing the
- a cartridge is proposed with at least one longitudinally extending receiving chamber for a medium to be discharged, with a head part and a cartridge wall, which limit the receiving channels, wherein a piston is provided which is insertable into the receiving chamber at the end facing away from the head part and sealingly displaceable along the cartridge wall in the longitudinal direction, and wherein the cartridge wall is made of a cardboard and is sealingly connected to the head part.
- paperboard also includes paperboard composites.
- Plastic cartridges are used.
- the use of cardboard is a great advantage, especially in terms of sustainability.

- the cartridge according to the invention offers the advantages of a conventional one in terms of its filling and its storability
- Cartridge so it does not have to be filled in elaborate filling devices as required for hoses in the rule and can be stored much easier, for example, standing.
- the piston provided for discharging the medium from the receiving chamber has the advantage that, as a rule, smaller residual bulk volumes remain in the cartridge, as a result of which the amount of waste is reduced. Furthermore, in chemical media in the receiving chamber by the
- the piston is preferably as a valve piston or
- the head part is made of a cardboard.
- the cartridge wall or the head part-in particular preferably both-comprise a foil which adjoins the receiving chamber
- the film provides a very efficient diffusion barrier, so that no concessions to the shelf life or the maximum storage time are necessary. Even with longer storage times, the cartridge contents are effectively protected against the outward or inward diffusion of substances or "outgassing."
- the cartridge wall or the head part is protected by the foil, for example if the carton material of the cartridge wall is sensitive to the medium in the receiving chamber
- the film offers a very high degree of flexibility with regard to the choice of material and can be adapted to the specific cartridge contents depending on the application Another advantage of the film is that, when the medium is being discharged, the friction between the cartridge wall and the cartridge is minimized Piston reduced.
- Cartridge wall to reduce compared to conventional cartridges, because the wall thickness is no longer needed as a means to avoid or reduce diffusion-related degradation processes.
- the cartridge wall has a wall thickness of at most 1 .0 mm, preferably of about 0.5 mm. This small wall thickness means in comparison to conventional cartridges a very significant reduction of waste and a reduction of the for the

- the adapter which includes the outlet, is placed on the header, with the outlet not yet having fluid communication with the receiving chamber.
- the invention further provides a multi-component cartridge
- the two cartridges are arranged side by side with respect to the longitudinal direction, or wherein the two cartridges are arranged inside each other, preferably coaxially with each other, so that the one cartridge encloses the other cartridge.
- the first variant involves so-called side-by-side cartridges in which the two receiving chambers are arranged side by side.
- the two cartridges are arranged inside each other, so that the cartridge wall of the outer cartridge completely surrounds the cartridge wall of the inner cartridge.
- the inner cartridge is centered in the outer cartridge, so that their longitudinal axes A coincide.
- the two cartridges are firmly coupled to each other via the connecting means, so that the multi-component cartridge forms a bearing and dischargeable unit.
- Cartridges for cooperation with an accessory are arranged and configured. In this way it is possible, for example, known per se accessories in conjunction with the
- Multi-component cartridge to use This compatibility is advantageous for practical and economic reasons
- a multi-component cartridge comprises a mixer configured to cooperate with the adapters and having two piercing elements, each of which may engage an outlet to open a flow communication with the respective receiving chamber.

- the adapter 5 is permanently connected to the head part 4, for example, welded or glued.
- the cartridge wall 3 is made of a cardboard and sealingly connected to the head part 4.
- paperboard is meant a material based on cellulose fibers or pulp or pulp or waste paper or combinations thereof, which usually, but not necessarily, comprises several layers of paper or paperboard
- the cartridge according to the invention particularly meets the requirements of environmental compatibility and sustainability.
- the head part 4 is also made of a cardboard.
- Fig. 1 shows in the upper detail view a way as the cardboard headboard 4 sealingly with the
