Abstract

Abstract A transport container which is suitable, in particular, for transport on airplanes, should be lightweight and, in addition, assure an absolute safe insulation of the interior of the container against severe climatic changes. This is particularly important when transporting art articles which otherwise could be damaged. In accordance with the invention, such a transport container is so structured that the walls and the lid consist of a plurality of layer zones which are coordinated with each other with respect to their efficiency characteristics--namely, an inner layer zone consisting of a rigid moisture-storing material, a heat-insulating material layer mounted atop the inner layer zone and covered on both sides with a water-impervious foil, a wide mesh-like grid structure which rests on the heat-insulating material layer and forms a plurality of air chambers and an outer wall of the transport container which covers the grid structure.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 130 words
A lightweight transport container for transporting goods which are sensitive to humidity and temperature changes, of the type composed of walls and at least one lid, the improvement comprising: said walls and lid each being composed of a plurality of layer zones which are coordinated with each other with respect to their operating characteristics, including an inner layer zone comprising a rigid, moisture-storing material, a heat-insulating material layer zone disposed atop said inner layer zone which is covered on both its inner and outer sides with a water impermeable foil, a wide mesh-like grid structure which rests on the foil covering the outer side of said heat-insulating material layer zone and forms a plurality of air chambers, and an outer wall for said transport container which covers said grid structure.
Claim 2
Dependent Claim 130 words
A lightweight transport container for transporting goods which are sensitive to humidity and temperature changes, of the type composed of walls and at least one lid, the improvement comprising: said walls and lid each being composed of a plurality of layer zones which are coordinated with each other with respect to their operating characteristics, including an inner layer zone comprising a rigid, moisture-storing material, a heat-insulating material layer zone disposed atop said inner layer zone which is covered on both its inner and outer sides with a water impermeable foil, a wide mesh-like grid structure which rests on the foil covering the outer side of said heat-insulating material layer zone and forms a plurality of air chambers, and an outer wall for said transport container which covers said grid structure.
Claim 3
Dependent Claim 18 words
The transport container according to claim 1, wherein said foil consists of water vapor-tight material having reflective surfaces.
Claim 4
Dependent Claim 43 words
The transport container according to claim 1 or 2, wherein said inner layer zone comprises wood, and wherein said inner layer zone has an inner face which limits the inner space of the container which is covered with a fine fibered textile material.
Claim 5
Dependent Claim 12 words
The transport container according to claim 3, wherein said wood is beechwood.
Claim 6
Dependent Claim 34 words
The transport container according to claim 1 or 2, wherein said outer wall comprises a thermal insulation material which is reinforced on both sides with a foil consisting of highly rigid and reflective material.
Claim 7
Dependent Claim 47 words
The transport container according to claim 1, wherein said lid has an edge which completely overlaps the container walls in a sealing manner and is mounted thereon with screws, said lid in said mounted state projecting into the inner chamber of the container defined by said walls.
