## Abstract

A vacuum insulation body comprising at least one vacuum-tight covering that surrounds at least one evacuated region, wherein one or more core materials are arranged in the evacuated region, and wherein the vacuum-tight covering has at least one evacuation opening that is provided with at least one valve having at least one valve disk that opens the evacuation opening in the opened state and that releases the evacuation opening in the closed state, with means for a vacuum-tight sealing of the evacuation opening being arranged outside the sealing region of the valve disk.

## Claims

### Claim 1

A vacuum insulation body comprising at least one vacuum-tight covering that surrounds at least one evacuated region, wherein one or more core materials are arranged in the evacuated region,
characterized in that
the vacuum-tight covering has at least one evacuation opening that is provided with at least one valve having a valve disk that opens the evacuation opening in the opened state and that releases the evacuation opening in the closed state, with means for a vacuum-tight sealing of the evacuation opening being arranged outside the sealing region of the valve disk.

### Claim 2 (depends on 1)

The vacuum insulation body in accordance with claim 1, characterized in that the means for the vacuum-tight sealing are formed by one or more plastic layers; and/or in that the vacuum-tight sealing is configured such that the gas introduction rate through the evacuation opening is in the range ≤10−8-10−6 mbar*l/s in the state with a vacuum-tight seal.

### Claim 3 (depends on 2)

The vacuum insulation body in accordance with claim 2, characterized in that the plastic is a polyolefin.

### Claim 4 (depends on 1)

The vacuum insulation body in accordance with claim 1, characterized in that the valve disk cooperates in the closed state of the valve with a valve seat whose sealing material has a Shore hardness ≤80 Shore.

### Claim 5 (depends on 1)

The vacuum insulation body in accordance with claim 1, characterized in that the valve disk has at least one magnetic material that is arranged such that it can cooperate with at least one external magnet.

### Claim 6 (depends on 1)

The vacuum insulation body in accordance with claim 1, characterized in that the valve disk and/or the valve seat that cooperates with the valve disk with a closed valve has/have at least one centering aid.

### Claim 7 (depends on 1)

The vacuum insulation body in accordance with claim 1, characterized in that the valve disk and/or the valve seat that cooperates with the valve disk with a closed valve is/are totally or partially elastic.

### Claim 8 (depends on 1)

The vacuum insulation body in accordance with claim 1, characterized in that the valve seals without a vacuum-tight sealing in the closed state such that the gas introduction rate through the valve is in the range ≤10−5-10−3 mbar*l/s.

### Claim 9 (depends on 1)

The vacuum insulation body in accordance with claim 1, characterized in that the means for the vacuum-tight sealing are formed in part or in full by one or more high barrier films.

### Claim 10 (depends on 1)

The vacuum insulation body in accordance with claim 1, characterized in that the vacuum insulation body has at least one stable area element that forms the valve seat of the valve disk, on the one hand, and that serves as a support for the step of the vacuum-tight sealing, on the other hand.

### Claim 11 (depends on 10)

The vacuum insulation body in accordance with claim 10, characterized in that the area element is configured such that the valve terminates flush with the sections surrounding the valve and forms a planar surface overall in the closed state.

### Claim 12 (depends on 1)

An arrangement comprising at least one vacuum insulation body in accordance with claim 1 and at least one suction cup that is placed onto the evacuation opening of the vacuum insulation body, wherein the suction cup lies sealingly on the vacuum insulation body in the region around the evacuation opening, and wherein the suction cup has at least one region in a vacuum in which at least one lifting element is arranged to open the valve such that the interior of the vacuum insulation body can be evacuated, with the lifting element or another element being suitable to close the valve again after the evacuation process has taken place.

### Claim 13 (depends on 1)

A method of evacuating one or more vacuum insulation bodies in accordance with claim 1, characterized in that at least one suction cup is placed onto the vacuum insulation body for the purpose of evacuating the vacuum insulation body, the suction cup sealing the region around the valve disk and having at least one lifting element, and with the valve disk being raised for the purpose of evacuation and with the evacuation opening thus being opened, and with the valve disk again being lowered onto the evacuation opening after the evacuation.

### Claim 14 (depends on 13)

The method in accordance with claim 13, characterized in that the valve disk is moved by at least one electromagnet of the suction cup.

### Claim 15 (depends on 13)

The method in accordance with claim 13, characterized in that the evacuation process of the vacuum insulation body runs sequentially at one or more suction cups; and in that the evacuation opening of the vacuum insulation body is closed by the valve disk on the transfer of the vacuum insulation body between the evacuation stations or between two evacuation processes.

### Claim 16 (depends on 13)

The method in accordance with claim 13, characterized in that the vacuum-tight sealing takes place after the last evacuation process, with the vacuum-tight sealing.

### Claim 17 (depends on 1)

A thermally insulated container, having at least one temperature-controlled inner space and having at least one wall at least regionally surrounding the temperature-controlled, inner space, wherein at least one vacuum insulation body in accordance with claim 1 is located between the temperature-controlled inner space and the wall.

### Claim 18 (depends on 17)

The thermally insulated container in accordance with claim 17, characterized in that no further thermal insulation is present between the inner space and the wall except for the vacuum insulation body.

### Claim 19 (depends on 7)

The vacuum insulation body of claim 7, wherein the valve disk and/or the valve seat has/have at least one flat seal, that seals the valve.

### Claim 20 (depends on 12)

The arrangement of claim 12, wherein the lifting element is designed as an electromagnet.
