Abstract: A container may be provided, in particular a beverage container, comprising an inner container wall and an outer container wall, an intermediate space lying between the container walls, wherein the intermediate space is filled with a mixture that contains phase-change material and graphite powder, wherein the graphite powder is introduced into the phase-change material in such a way that the mixture has a pulpy consistency at a temperature at which the phase-change material is liquid. A method may be provided for producing a container that includes the following steps: A) providing an inner container wall and an outer container wall; B) applying a mixture of graphite powder and phase-change material to the inside of the outer container wall and/or the outside of the inner container wall; C) joining the outer container wall and the inner container wall.

Abstract: The invention relates to a heat-insulating container with a surrounding wall (5, 6) that encloses a space for holding foodstuffs or beverages, whereby latent heat storage material (4) is accommodated inside the surrounding wall. A lightweight supporting structure (7) is placed between an inner (5) and an outer (6) casing, which form the surrounding wall, and the supporting structure is filled with the latent heat storage material (4).
