Abstract
An axially crushable bottle made of plastics material and formed with transverse corrugations over the major portion of its height has fold starters in each corrugation, which fold starters project outwards from the bottoms of the corrugations and are angularly offset from one corrugation to another.
Claims29
An axially crushable bottle made of plastics material, the bottle comprising transverse corrugations over a major portion of its height, said transverse corrugations comprising a cylindrical wall portion and a depressed groove portion, wherein said transverse corrugations have a depth, i.e., a dimension measured towards the axis of the bottle, that varies cyclically around the periphery of said groove portion of said corrugations between a maximum value and a minimum value, and wherein groove portions of successive transverse corrugations are separated by said cylindrical wall portion.
An axially crushable bottle made of plastics material, the bottle comprising transverse corrugations over a major portion of its height, wherein said transverse corrugations have a depth, i.e., a dimension measured towards the axis of the bottle, that varies cyclically around the periphery of said corrugations between a maximum and minimum value, and wherein the bottle further comprises fold starters formed to project radially outwards from the bottoms of said corrugations, said fold starters being uniformly distributed and angularly offset around the axis of the bottle from one corrugation to another, and wherein the radial extent .lambda. of each of said fold starters in the midplane of said corrugation is about half the depth of said corrugation.
An axially crushable bottle made of plastics material, the bottle comprising transverse corrugations over a major portion of its height, said corrugations comprising right cylindrical portions alternating with depressed grooves, said grooves being formed with fold starters which project radially outward from the bottoms of said grooves and which are uniformly distributed and angularly offset around the bottle from one groove to another.
