Flexible sorption cooling elements
First Claim
1. A cooling element with a sorption agent that under vacuum can sorb a working agent in vapor form, which evaporates from a liquid amount of working agent in an evaporator region, and with a shutoff device, which, before initiating the cooling process, keeps the working agent vapor from being able to flow to the sorption agent,wherein the sorption agent and the evaporator region are surrounded by a multilayer film and the evaporator region contains a nonwoven and a flexible structural material, which together under vacuum can take on a flat flexible shape, which can be pressed against the containers that are to be cooled andthe structural material, after the start of the cooling element, can conduct the working agent vapor up to the sorption agent and keeps a flow cross section of at least 1 square centimeter (cm2) open for the working agent vapor.

Abstract
A cooling element with a sorption agent (11, 33) that, under vacuum, can sorb a vapor working agent, which evaporates from a liquid amount of working agent in an evaporator region (16, 22), and with a shutoff device, which, before initiating the cooling process, keeps the working agent vapor from being able to flow to the sorption agent (11, 33), and where the sorption agent (11, 33) and the evaporator region (16, 22) are surrounded by a multilayer film (1, 6, 31, 32) and the evaporator region (16, 22) contains a nonwoven (5, 36) and a flexible structural material (2, 35), which together can take on a flat flexible shape under vacuum, that can be pressed onto the containers (14, 24) that are to be cooled, and the structural material (2, 35), after the start of the cooling element, can conduct the working agent vapor up to the sorption agent (11, 33) and keep a flow cross section of at least 1 square centimeter (cm2) open for the working agent vapor.
