Abstract

The present invention relates to a vacuum insulation body with at least one vacuum-tight casing and with at least one vacuum region which is surrounded by the casing, wherein the casing is provided with at least one opening, in particular with at least one evacuation port, for evacuating the vacuum region, and wherein in the vacuum insulation body at least one adsorbent material is disposed, which partly or entirely is arranged in the region of said opening, wherein around the opening and within the vacuum range at least one plate is arranged, which forms a wall of the space in which the adsorbent material is disposed.

Claims

1. A vacuum insulation body with at least one vacuum-tight casing and with at least one vacuum region which is surrounded by the casing, wherein the casing is provided with at least one opening, in particular with at least one evacuation port, for evacuating the vacuum region, and wherein in the vacuum insulation body at least one adsorbent material is disposed, which partly or entirely is arranged in the region of said opening,

characterized in

that around the opening and within the vacuum region at least one plate is arranged, which forms a wall of the space in which the adsorbent material is disposed.

4. The vacuum insulation body according to claim 1, characterized in that the adsorbent material is present in the form of a plurality of individual bodies.

5. The vacuum insulation body according to claim 1, characterized in that at least one filter material which extends between the core material of the vacuum insulation body and the adsorbent material.

6. The vacuum insulation body according to claim 5, characterized in that the filter material is thermally sealed with the plate and/or with the molded part and/or with the casing.

7. The vacuum insulation body according to claim 1, characterized in that the vacuum-tight casing consists of a high-barrier film.

8. The vacuum insulation body according to claim 1, characterized in that the vacuum-tight casing extends around the opening of the casing and/or adjoins the plate on the outside.

9. The vacuum insulation body according to claim 1, characterized in that the plate and the molded body consist of different parts which are latched or thermally sealed with each other, or that the plate and the molded body consist of one common part.

10. The vacuum insulation body according to claim 9, characterized in that the adsorbent material is present in the form of a plurality of individual bodies.

11. The vacuum insulation body according to claim 1, characterized in that the adsorbent material is arranged directly adjacent to the opening and/or directly adjacent to the molded part and/or is arranged such that it surrounds the opening and/or the molded part.

12. The vacuum insulation body according to claim 1, characterized in that the adsorbent material is arranged in a region which is adjacent to the opening and/or to the molded part.

13. The vacuum insulation body according to claim 1, characterized in that the adsorbent material is arranged such that the gas passing through the opening during generation of a vacuum partly or completely passes through the adsorbent material.

14. The vacuum insulation body according to claim 1, characterized in that the adsorbent material is formed such that it adsorbs water and/or nitrogen and/or oxygen and/or that the adsorbent material is at least one getter and/or drying agent, in particular zeolite.

15. A heat-insulated container with at least one body and with at least one tempered interior space which is surrounded by the body, and with at least one closure element by means of which the tempered interior space can be closed, wherein between the tempered interior space and an outer wall of the container at least one interspace is disposed,

characterized in

that in the interspace at least one vacuum insulation body with the features of claim 1 is arranged.

2. A vacuum insulation body with at least one vacuum-tight casing and with at least one vacuum region which is surrounded by the casing, wherein the casing is provided with at least one opening, in particular with at least one evacuation port, for evacuating the vacuum region, and wherein in the vacuum insulation body at least one adsorbent material is disposed, which partly or entirely is arranged in the region of said opening,

characterized in

that between the adsorbent material and the opening at least one molded part is arranged, which includes one or more molded part openings whose flow cross-section is larger than the flow cross-section of the opening of the casing.

3. The vacuum insulation body according to claim 2, wherein that around the opening and within the vacuum region at least one plate is arranged, which forms a wall of the space in which the adsorbent material is disposed.
