Bottle dome

Provided is a bottle with a handle including a bottle in which a mouth portion, a body portion, and a bottom portion are continuously provided in this order along a direction of a bottle axis, and a handle disposed in a rear part of the bottle, wherein a first circumferential groove extending in a circumferential direction along the bottle axis is formed in a lower body portion of the body portion located between the handle and the bottom portion along the direction of the bottle axis, and the first circumferential groove is disposed over the entire region in the circumferential direction in a portion of the bottle along the circumferential direction in which the handle is located.

The technical problem to be solved by this invention is to design bottle walls having such a shape as to inhibit cave-in deformation into a dented wall shape caused by recessed areas for fingerhold. The object of this invention is to provide a synthetic resin square bottle which is usable without anxiety, is excellent at firm hold, and has a high vacuum-absorbing function. In a synthetic resin square bottle comprising a body formed by multiple panel walls disposed on the body in a circumferential direction, and a waist portion made of a peripheral groove dented at a roughly middle height position of the body so as to divide each panel wall into an upper panel and a lower panel, recessed areas for fingerhold use are formed in at least a pair of opposing panel walls in a certain area ranging from the waist portion to an upper end portion of the lower panel of each panel wall, and a pair of side ribs is formed on right and left sides of, and in the vicinity of, each recessed area in the lower panel.

Bottle

A container has a body which comprises front end rear walls, and the side walls. Each of the front and rear walls has an elliptic cross section, and is provided with a lateral recess. Each of the side walls is a vertical plan which intersects the elliptic cross section of the front and rear walls, and is provided with a plurality of reinforcements. The container has a bottom which comprises a peripheral wall connected to the body and a bottom wall. The peripheral wall comprises slightly inclined front and rear walls, and side walls inclined by a predetermined angle. The peripheral wall is provided with a reinforcing rib.

Synthetic resin container with thin wall

In a bottle-shaped synthetic resin container having a body part of substantially rectangular tubular shape, groove ribs, having a comparatively wide vertical groove form, are depressingly provided at the centers in the width direction of flat wall portions of shoulder lower end parts, which are portions of a shoulder part that connect with the body part, to make these portions higher in rigidity and difficult to deform and, even when a deformation occurs, prevent the deformation from becoming a permanent deformation. Safe handling of the container is thus promoted, especially for the stacked storage of containers in a sideways-laid orientation.

The technical problem of this invention is to eliminate the need to use deformable panel walls and to find the body of a shape that no false deformation, such as dented deformation, takes place in a portion of the body due to the hot filling of the contents or the reduced pressure created by the treatment of retort-packed foods. The object of this invention is to obtain a bottle that can inhibit the deformation caused by reduced pressure, has a high buckling strength, and is good in outer appearance. As the solution, there is provided a biaxially drawn, blow-molded bottle made of a synthetic resin, in which the surface rigidity of the wall of body is set in such a manner that a part of the body wall cannot become dented inward under a reduced inner pressure of at least 350 mmHg (46.7 kPa).
