Abstract

Heat-insulating, plastics, container comprises >=2 structures of plastics film, 1 fitted inside the other and both connected together in places. Between the inner and outer walls there are 1 or several insulating compartments that may be inflated by a user. The article, as claimed is a bag or sack, with the component plies being connected by weld seams which thus also define the compartments.
