Inside the spatial structure there is at least one movable section (2) led vertically in a sliding guide. Between the movable section (2) and the spatial structure there is at least one elastic push element, which is adapted to push the movable section (2) upwards in its upper position and preferably also to push it downwards when the movable section (2) is in the lower position. The angle of inclination α of the elastic push element is less than 90°. The compartments are formed by sewing textile or other semi-rigid flat material. The compartments of the central zone are foldable to allow the movable section (2) to be moved to the central zone when empty, from where the parts are removed most easily and conveniently. The foldable compartments are preferably suspended from the upper movable section (2). The solution may also include a fork holder (13) for placing or hanging the parts.

The non-return valve has blades (2) in the closed position in two divergent half-planes (4). The intersection of the first half-plane (4) and the second half-plane (4) is identical with or parallel to the axis of the blades (2) or to the axes of the blades (2), while at least part of the counterweight (6) is located in the half-space opposite the half-space with the blade (2). The angle formed between the first half-plane (4) and the second half-plane (4) from the gas inlet side is 180° + 2α, where α is in the range up to 45°, preferably 1° to 30°, especially preferably 11°. The blades (2) in the closed position abut with their edges to the contact strip (7), which is fixedly attached to the edge of the body (1), while lying in the half-planes (4). The blade (2) is balanced to the axis of the shaft (3), while the counterweight (6) and the arm (5) can be formed in one piece, preferably from a steel wire with a circular cross-section. The partition (8) can have uneven edges, preferably it has wavy and/or sawtooth-like and/or sinusoidal edges.

Metal foam (1) is placed inside the casing (2), whereby at least part of the casing (2) is from malleable thin-layered material, which is designed for deformation during an underpressure inside the casing (2). The metal foam (1) is at adjacent contact with at least 75% of the surface of the inner wall of the casing (2) and inside the casing there is the underpressure against the outside environment with difference at least 5% at the whole temperature operation range. The malleable thin-layered material is a metal sheet or a metal foil, preferably aluminum sheet or an aluminum foil with thickness up to 1,0 mm. The metal foam (1) is aluminum-based and it has closed structure of the pores; it has at least 20 pores per 1 cm³ and its porosity is 88% at maximum. During the production, one follows the method where PCM substance (3) in the liquid state is placed into 95% to 98% of the available inside porous volume of the metal foam (1) at maximum, and then the component of the metal foam (1) is hermetically closed into the casing (2) with permanent underpressure inside the casing (2).
