Embodiment Construction

[0059] figure 1 A cooling and / or freezing device, for example a cooling and freezing cabinet with a cooled interior 12 is shown at 10 . in accordance with figure 1 In the view of , the cooling or freezer is shown upside down so that the open side of the inner container is underneath.

[0060] The cooled interior 12 is delimited by an inner container 20 and the outside of the tank is delimited by an outer shell 30 . Between these two elements there is a cover frame 40 which connects the inner container 20 and the outer shell 30 to one another. These elements together form an envelope whose interior is at least partially filled with vacuum insulation.

[0061] The vacuum insulation comprises a high barrier film 100 stretched on the inner side of the inner container, of the cover frame and of the outer shell, and which has according to figure 1 Fill opening 110 located above.

[0062] The envelope or vacuum insulation is formed as a three-dimensional structure.

Abstract

The invention relates to a vacuum insulation body, comprising a vacuum-tight casing, which encloses an evacuated region, wherein a core material is arranged in the evacuated region, wherein the casing has an opening for filling the casing with the core material, which opening is covered by a vacuum-tight covering film, wherein the casing is folded inward in the edge region projecting toward the opening, the opening therefore being reduced, and then is folded outward again, wherein the region folded outward and a region of the covering film are connected to each other peripherally in a vacuum-tight manner.

Description

technical field [0001] The invention relates to a vacuum insulation body comprising a vacuum-tight envelope surrounding an evacuated region in which a core material, such as pearlite, is arranged . Background technique [0002] Such a vacuum insulation is known, for example, from DE 10 2013 005 585 A1. The vacuum insulation known from this patent application consists of a diffusion-tight, i.e. vacuum-tight, envelope whose surface is larger than that of the envelope body, for example the inner container, against which the envelope rests. On the body of the bag. It is thus possible, for example, to reproduce a protruding or retracted contour of the wrapping body in the wrapping. [0003] Fillers are preferably introduced into the envelope during the production of the vacuum insulation. In order to be able to carry out this introduction of the filler material in a meaningful way, openings are provided in the jacket, which openings must be closed vacuum-tight after the filli...
