  • Patent number: 8978910
    Abstract: A technical problem of this invention especially in the case of large-size bottles is to form a grip, without changing the bottle shape to a large extent, so that the body can be firmly held. The object of this invention is to provide a synthetic resin square bottle that can be used reliably because the bottle can be held firmly with a hand. A major means of solving the problem is a synthetic resin square bottle comprising a body having a rectangular shape in a plane cross-section and a groove-like waist portion disposed at a middle height of the bottle, wherein a pair of recessed portions for use as finger stops are formed in respective long side walls of said rectangular body over a predetermined area ranging from said waist portion downward to ensure that a plural number of fingers can be placed in at least one recessed portion for a finger stop purpose, and wherein a grip for holding the bottle is formed from both the pair of recessed portions and the waist portion.

  • Patent number: 8544667
    Abstract: A round bottle that gives an overall impression of a slim body, while maintaining a basic shape of the round bottle and a vacuum absorbing function. An object is to provide a round synthetic resin bottle having a differentiated shape not found in conventional art. This involves narrowing down a diameter of the body in a tapered manner toward a middle height position of the body to form a tapered portion at either one of an upper end or a lower end of the basically cylindrical body and thus to form a waist portion in a narrowest part of this tapered portion, and forming a plurality of dented vacuum absorbing panels in a height range lying next to the waist portion of the body and in a configuration that each of the panels is disposed in parallel in a circumferential direction and dented by a stepped portion surrounding each panel.

  • Patent number: 8113368
    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 (?) 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.
