Isotherme Verpackung und Verfahren zu ihrer Herstellung

摘要

The insulated package is made by injecting a polymer foam and expanding it in the space between inner (10) and outer (11) containers made from cut and folded cardboard and assembled one inside the other. The inner container is placed over a mould, a sealing strip (12) is fitted round the top of the gap, and the space (VI) between the two containers is filled with an injected polymer foam after placing the assembly inside a cage that retains the pressure created by the injected foam. The package is closed by a lid (2) of similar construction, having a block (22) on the underside that fits into the top of the inner container. The components are removed from the mould once the foam has set.
