Single mould for industrial stacking bins

摘要

The bins, pref. rectangular, have four side walls, and a plain upper edge all around the top. The lower, bin-shaped mould (10), mates with the moving upper mould (12), to define the walls and base of the bin, by their enclosing surfaces (18,16,20,22). A thin fluid material; hardening plastic, or a reaction mixture, is charged into the cavity defined (14), to make the bin. The filling piece arrangement (24) is made of an elastomeric, heat resistant material. Its lower edge (44) defines the top of the bin; its volume fills the unused top portion above the moulding cavity.
