Synthetic resin bottle with spirally inclined pillars

US-8113368-B2

Abstract

A synthetic resin bottle is provided with a shape that improves rigidity and strength in a lateral direction, without increasing the cost of material to thicken the bottle wall. The synthetic resin bottle is provided at a low cost in such a way that the bottles can be used smoothly on the carrier line, in vending machines, and in storage in stacks with no deformation. The bottles are capable of performing a vacuum-absorbing function enough to be used in hot filling. Multiple pillar sections in a projected strip-like shape are disposed on the body of a synthetic resin bottle, the pillar sections being inclined spirally at a uniform angle of gradient (α) relative to a central axis of the bottle and disposed in parallel to one another, so that the cylindrical body wall is prevented from being deformed by a pressure force acting in a lateral direction.
