Definitions
- the present invention relates to an extrusion container made of plastic.
- Press-out containers such as cartridges or tubes must often have a high barrier to water vapor, gases or solvents to prevent the passage of these substances through the container wall.
- squeeze containers For example, in a squeeze container containing a substance with solvent, it must be ensured that the solvent does not escape through the wall. On the other hand, in the case of a squeezing container which contains a curable synthetic material, it must be ensured that no hardening or reactive gases or vapors penetrate. Since squeeze containers are also used for perishable products, such as food, a sufficient barrier against environmental influences must be ensured. Other squeeze containers must have a barrier against migrating materials, such as oils and dyes, which may leak out of the package or through the package wall.
- Press-out containers are often made of plastic. There is basically the problem that the barrier effect with respect to solvents, water vapor or gases depends on the corresponding wall thickness of the plastic material.

- the coating 23 is particularly advantageous to apply the coating 23 according to the invention to the end wall 14 and the front region of the cartridge so that a change, for example hardening of the extrudable mass, is prevented, in particular in this front region of the cartridge.
- a hardening of the mass in this front region would mean that the remaining in the container body 11 located squeezable mass would no longer be used, since this would not be removed from the squeeze container 11.
- Coating in the context of the present invention means a firmly adhering layer of shapeless material.
- the coating 23 is applied to the outside of the container body 11.
- the coating can be applied, for example, by a vapor deposition method, for example a CVD or PVD method.
- the gas-phase deposition can be carried out in plasma or plasma-assisted.
- the coating 23 can also be printed or sprayed on.
- the coating has the effect that, in particular, the regions of the container body, on whose surface the coating 23 is applied, can be of a smaller wall thickness. As a result, in the manufacture of the container body 11 material can be saved, which is in economic and environmental terms of advantage.

- the predetermined breaking point 20 is formed as a section with reduced wall thickness.
- This area is particularly at risk in conventional Auspress employern because the end wall 14, the Collar wall 15 or the predetermined breaking point 20 due to their arrangement or the material wall or material thickness are often areas in which there is a reduced barrier effect.
- Changing the extrudable mass in this area is of particular disadvantage, since, for example, curing of the extrudable mass can lead to clogging of the outlet opening 30, so that the rest of the extrudable mass received in the ejection container 10 is no longer accessible and thus no longer used can.
- the coating 23 according to the invention reduces the risk of altering the extrudable mass in this area.
