Disposable stackable case with press moulded components - with side panels with obtuse-angled adjacent edges

摘要

Disposable stackable case consists of components moulded from a pressed mixture of lignocellulosic fibres and a hardened binder. The cae comprises a frame with two pairs of planar square or rectangular panels, of the same shape but different dimensions, and a bottom fitted in the frame. The adjacent edges of the panels are directed outwards at an obtuse angle along most of their length. The upper edges of the penels each have a rim forming an enlarged supporting surface at the corners (2'), while their lower edges are offset inwards. A rectilinear groove parallel to the lower edge is formed in a single stage above the lower edge.
