Abstract
A pressure resistant bottle-shaped container having a body including panels surrounded by outer sheaths, characterized in that each panel has stress absorbing strips comprising vertexes recessed from the outer surface of the panel toward the interior of the container and bending lines formed in V shape and inverted V shape from the vertexes toward the outer sheaths. Thus, the container does not retain permanent deformation by the deformations resulting from pressure changes at the time of filling high temperature liquid content.
Claims5
A pressure resistant bottle-shaped container having a body with an outer surface including panels surrounded by outer sheaths, wherein:
- each panel has a longitudinal height and a transverse width, and includes stress absorbing tones comprising vertexes recessed from the outer surface of the panel toward the interior of the container and bending lines formed, in V shape and inverted V shape in mirror-image, confronting relationship from the vertexes toward the outer sheaths,
- said vertexes are formed on the center line of the panel along the longitudinal height of the panel,
- a flat recessed portion is formed between the vertexes at the center of the longitudinal height of the panel, and
- a depth of a recessing step between the surface of the panel and the flat portion is 1.0 mm or less.
