摘要：
A pouch (100) filled with phase-change material, wherein the pouch comprises a preformed first wall (110) and a second wall (120), wherein the first wall comprises a bowl-shaped part, in which the phase-change material is accommodated, and a peripheral part, wherein the second wall is attached to the peripheral part of the first wall, wherein a high vacuum prevails in the pouch, and wherein the pouch is intended for placing against a wall to be heated or cooled.
权利要求：
1. Claims 1.A pouch filled with phase-change material, wherein the pouch comprises a preformed first wall and a second wall, wherein the first wall comprises bowl-shaped part, in which the phase-change material is accommodated, and a peripheral part, wherein the second wall is attached to the peripheral put of the first wall wherein a high vacuum prevails in the pouch, and wherein the pouch is intended for placing against a wall to be heated or cooled.
2. The pouch as claimed in claim 1, wherein the first wall and second wall are at least 40 µm thick and preferably between 50 µm and 150 µm thick.
3. The pouch as claimed in claim 1 or 2, wherein the first wall is a first film and the second wall is a second film.
4.The pouch as claimed in the foregoing claim, wherein the bowl-shaped part of the first wall is formed by thermoforming the first film.
5. The pouch as claimed in any of the foregoing claim, wherein the first wall and second wall each comprise a welding layer and a barrier layer, wherein the welding layer of the first wall is welded to the welding layer of the second wall
6. The pouch as claimed in the foregoing claim, wherein the welding layer comprises polypropylene and the barrier layer comprises polyamide.
7. The pouch as claimed in any of the foregoing claims, wherein the first wall and/or the second wall comprises a layer manufactured from aluminium.
8. The pouch as claimed in claim 1 or 2, wherein the first wall and/or the second wall are manufactured by injection moulding.
9. The pouch as claimed in any of the foregoing claims, wherein the pouch is intended for placing with the second wall against a part to be heated or cooled, and wherein the first wall has better thermally insulating properties than the second wall.
10. The poach as claimed in any of the foregoing claims, wherein the pouch is filled with phase-change material not accommodated in capsules. 15
11. The pouch as claimed in any of the foregoing claims, wherein the second wall is a preformed wall.
12. A piece of crockery provided with a poach as claimed in any of the foregoing claims, wherein the pouch is situated in the crockery and wherein the pouch is placed with the second wall against a wall of the crockery to be heated or cooled. 3. A method for manufacturing a pooch filled with phase-change material, wherein the method comprises of; - shaping a first wail of the pouch such that the first wall comprises a bowl- shaped part and a peripheral part; - placing the phase-change material in the bowl-shaped part of the shaped first wall; - attaching a second wall of the pouch to the peripheral part of the shaped first wall such that the phase-change material is situated between the first and second walls, and that a high vacuum prevails in the pouch.
14. The method as claimed in claim 13, wherein the shaping of the first wall of the pouch comprises of thermally preforming the first wall of the pouch.
15. The method as claimed in claim 13, wherein the shaping of the first wall comprises of injection moulding the first wall.
16. The method as claimed in any of the foregoing claims 13 to 15, wherein attaching the second wall to the peripheral part of the shaped first wall comprises of: positioning the first and second wall relative to each other such that the second wall is attachabIe tho peripheral part of the first wall; drawing a vacuum in the space between the first wall and the second wall; and sealing the pouch at the peripheral part of the first wall.
17. The method as claimed in claim 16, wherein sealing of the pouch at the peripheral part of the first wall comprises of welding or gIueing the second wall to the peripheral part of the first walls.
18. The method as claimed in any of the foregoing claims 13 to 17, wherein placing of the phase-change material in the bowl-shaped part of the shaped first wall comprises of melting the phase-change material, casting the molten phase-change material in a mould and, after cooling, placing the hardened phase-change material the bowl-shaped part.
19. The method as claimed in any of the foregoing claims 13 to 18, comprising of shaping the second wall of the pouch prior to the attachment.
20. The method as claimed in claim 19, wherein the shaping of the second wall comprises of injection moulding the second wall or thermally preforming the second wall.
