Abstract

A receptacle for storing a substance, wherein the receptacle has a cartridge and a valve. A valve inner side is here covered by a sealing element, with the result that a receptacle volume is substantially delimited by the cartridge and the sealing element.

First claim

The invention claimed is:

1. A receptacle for storing a substance, the receptacle comprising a cartridge and a valve, wherein a side of the valve within the cartridge is covered by a sealing element, with the result that a receptacle volume is delimited by the cartridge and the sealing element, wherein
in a storage state of the receptacle, the receptacle volume is sealed from an outside volume by the sealing element and by a seal of the valve, and the sealing element surrounds the valve within the cartridge, such that the valve is separated from the receptacle volume by the sealing element,
in a closed use state of the receptacle, the receptacle volume is sealed from the outside volume only by the seal of the valve, and
in an opened use state of the receptacle, the receptacle volume is connected to the outside volume by a through-passage of the valve.

2. The receptacle as claimed in claim 1 , wherein the receptacle is under pressure, with the result that the substance flows out of the receptacle upon an actuation of the valve.

3. The receptacle as claimed in claim 1 , wherein an adhesive or sealant is arranged for storage in the receptacle.

4. The receptacle as claimed in claim 1 , wherein the sealing element is a foil.

5. The receptacle as claimed in claim 1 , wherein the foil has a thickness of 5 to 30 μm.

6. The receptacle as claimed in claim 1 , wherein walls of the cartridge are formed from metal.

7. The receptacle as claimed in claim 1 , wherein the valve has a housing, a plunger, a through-passage, a seal and a fastening element.

8. The receptacle as claimed in claim 7 , wherein, in a closed state of the valve, the through-passage is closed by the seal, and wherein the plunger is displaceable in the housing in such a way that, in an opened state of the valve, the through-passage forms a connection between the receptacle volume and an outside volume.

9. The receptacle as claimed in claim 7 , wherein the seal is formed from rubber.

10. A method for sealing a receptacle having a cartridge and a valve, the method comprising the following steps:
providing a sealing element;
shaping the sealing element;
covering a side of the valve within the cartridge with the shaped sealing element; and
fastening the valve with the sealing element to the cartridge, with the result that a receptacle volume is delimited by the cartridge and the sealing element, and the sealing element surrounds the valve within the cartridge, such that the valve is separated from the receptacle volume by the sealing element.

11. The method as claimed in claim 10 , wherein a piece of aluminum foil is provided when providing the sealing element.

12. The method as claimed in claim 10 , wherein, when shaping the sealing element, the sealing element is placed by a first shaping element over a second shaping element, with the result that the sealing element assumes a shape of the second shaping element, wherein the second shaping element has a part-ball-like shape.

13. The method as claimed in claim 10 , wherein the method comprises the following step:
subjecting the receptacle to pressure, with the result that a substance flows out of the receptacle upon an actuation of the valve, and with the result that the sealing element is pressed onto the side of the valve within the cartridge.

14. The method as claimed in claim 10 , wherein the receptacle is formed for storing a substance, the receptacle comprising a cartridge and a valve, wherein the side of the valve within the cartridge is covered by a sealing element, with the result that a receptacle volume is delimited by the cartridge and the sealing element.

15. A receptacle for storing a substance, the receptacle comprising a cartridge and a valve, wherein a side of the valve within the cartridge is covered by a sealing element, with the result that a receptacle volume is delimited by the cartridge and the sealing element, wherein
in a storage state of the receptacle, the receptacle volume is sealed from an outside volume by the sealing element and by a seal of the valve, and the receptacle volume is completely delimited by a single boundary set by the cartridge and the sealing element,
in a closed use state of the receptacle, the receptacle volume is sealed from the outside volume only by the seal of the valve, and
in an opened use state of the receptacle, the receptacle volume is connected to the outside volume by a through-passage of the valve.
