FOLDABLE PLASTIC BOTTLE, MOLD FOR MAKING THE BOTTLE, AND METHOD OF FOLDING EMPTY PLASTIC BOTTLE

摘要

A plastic blow-moulded bottle for beverages has been designed to be easily foldable. Its bottom part (3) has a V-shaped inward inlet (13) with an jointing edge at the apex. The sides (12) meet at an obtuse outward angle along a folded edge (15). ALl these edges lie in the longitudinal plane. When empty, the bottle is folded flat and is prevented from springing back by tightening a screw cap (7).
