FOLDING CASE MADE OF FOAMING SYNTHETIC RESIN

摘要

PURPOSE:To obtain a folding case made of foaming synthetic resin having side plates foldable relative to a bottom plate. CONSTITUTION:The folding case made of foaming synthetic resin is provided with a square bottom plate 11, a pair of side plates 14 formed on a pair of opposite sides 12 of the bottom plate 11 integrally therewith via depth set hinges 13 and in an upright position and adapted to fold over the upper surface of the bottom plate 11 on the depth set hinges 13 and a pair of side plates 17 formed on a pair of the other opposite sides 15 of the bottom plate 11 integrally therewith via V-shaped groove-like hinges 16 and in a horizontally opened condition and adapted to be reset in a standing position and folded over the lower surface of the bottom plate 11 on the V-shaped groove-like hinges 16. Since this permits the side plates 14 and 17 to be folded over the upper and lower surfaces of the bottom plate 11 in the transit and storage of such folding cases only, the occupying rate of a flat loading area is reduced and the breakage of the hinges 13 and 16 are prevented.
