On the other hand, such cartridges have the disadvantage that after opening the cartridge cannot be closed or is only closed impermissibly
[0006] However, such containers have the disadvantage that the storage capacity is not sufficient for all substances and applications until the first opening or use of the container

Embodiment Construction

[0032] exist figure 1 An exemplary container 1 with a cartridge 3 and a valve 2 according to the prior art is shown in . Said cartridge 3 and valve 2 delimit a container volume 4 relative to an external volume 15 . The valve has a valve outer side 5 adjoining the outer volume 15 and a valve inner side 6 adjoining the container volume 4 .

[0033] Such a container 1 is, for example, under pressure so that when the valve 2 is opened, the substance stored in the container 1 flows through the valve 2 into the outer volume 15 .

[0034] A disadvantage of this solution is the limited storage capacity for certain substances, such as polyurethane-containing water-curing adhesives or sealants. The usual valve 2 is sealed by a seal made of rubber. However, such seals are not completely airtight, so that a certain amount of water from the outer volume 15 passes through the seal to the container volume 4, where the water-curing adhesive or sealant starts to cure. Consequently, the subst...

Abstract

The invention relates to a container for storing substances, wherein the container has a cartridge (3) and a valve (2). Here, the inside of the valve is covered by the sealing element, so that the container volume is substantially delimited by the cartridge and the sealing element (12).

Description

technical field [0001] The invention relates to a container for storing substances and a method for sealing the container. Background technique [0002] On the one hand, closed cartridges are used for storing materials such as adhesives or sealants. Such cartridges can consist of metal or plastic. Here, the volume of the cartridge is completely defined by the material constituting the cartridge. In order to open the cartridge, generally a predetermined area of ​​the cartridge wall is broken. In order to use the substance of the cartridge, the opening in the wall of the cartridge can be fitted with a nozzle. Screws are usually provided on the cartridge for this purpose. [0003] Such a cartridge has the advantage that the substance is stored well until the cartridge is opened. Complete sealing of the cartridge volume from its surroundings can be achieved by a suitable choice of material forming the cartridge. On the other hand, such cartridges have the disadvantage that...
