FIELD: containers for various articles.
SUBSTANCE: box is made from foamed plastic and comprises casing and cover. Foamed plastic is foamed polyurethane with surface Shore hardness below 60 conventional units D. Casing and cover are made as individual members connected with one another through glued connection using polyurethane-based adhesive. Ratio of 8≤H/h≤120, where H is height of box, h is thickness of box walls, is true for said box.
EFFECT: increased workability, optimal hardness, density and wear-resistance ratio, and increased strength of surface layer.
