Method for making a self refrigerating drink container, comprises placing a heat exchanger within the drinks container with the enclosed refrigerating liquid frozen either previously or at the time

摘要

A heat exchanger (2) comprising tubes (3) and plates (31) is preferably made from the same material as a drinks container (10). The exchanger is secured inside the container with the refrigerating liquid (L) either previously frozen or frozen at the time. A press/puncture connection (5) consisting of complementary cones is made between a tube (4) at the base of the exchanger and an external adsorption pumping means (50). Independent claims are made for equipment to freeze the refrigerant, assemble the exchanger inside the container and produce a vacuum in the exchanger.
