A bottle having a storage chamber defined by spaced upper and lower surfaces and planar sidewalls; a conical ceiling in said upper surface having an opening at the top thereof; a conical convex recess in said lower surface for receiving the conical ceiling of the next adjacent bottle when stacking said bottles, and means for interlocking the sides and upper and lower surfaces of the bottles when stacked. The bottle may have ribs in the conical ceiling, conical recess and sidewalls for increasing top load resistance. A plurality of bottles may be assembled into a stable bottle stack with minimal packaging material. |
