<p>The technical problem to be solved by this invention is to design a bottle shape that improves the bottle rigidity and strength in the lateral direction, without increasing the cost of material required to thicken the bottle wall. The object of this invention is to provide a synthetic resin bottle at a low cost in such a way that the bottles can be used smoothly on the carrier line, in the vending machines, and in storage on the stacks with no deformation, and 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, wherein the pillar sections are inclined spirally at a uniform angle of gradient (a) relative to central axis of the bottle and disposed in parallel to one another, so that the cylindrical body wall is prevented from being deformed by the pressure force that acts in a lateral direction.</p> |
