ABSTRACT:
A collapsible container having substantially planar front and rear walls and interconnecting side walls that define inwardly extending V-shaped panels. A plurality of transversely extending stiffening grooves are provided in the front and rear panels to minimize outward bulging of the front and rear panels when the bottle is filled with a liquid material. A plurality of bridging members is formed in the side panels to bridge the adjacent side panels at a longitudinal fold line to minimize outward bulging of the side wall when the container is filled with liquid. To collapse the container the front and rear panels are urged together, and the side panels move inwardly about the longitudinal hinge line so that the bottle assumes a flat condition. The flattened bottle occupies considerably less space in waste disposal facilities.
