Large bottle-shaped container having substantially rectangular cross section

Abstract

A large container made of synthetic resin, and comprising a neck (1) and a body (2); said body having a substantially rectangular cross section, and including an upper body (11) and a lower body (12); said upper body (11) containing a center of gravity of the container when filled with liquid; said upper body (11) having a waist (13) section containing the center of gravity; said waist section (13) having a grip (14), said grip (14) being not adapted to absorb a negative pressure in the container; at least one surface of said lower body including a vacuum panel (16, 26). A large container made of synthetic resin, and comprising a neck (51) and a body (12); said body (12) having a substantially rectangular cross section, and including an upper body (61) and a lower body (62); said upper body (61) containing a center of gravity of the container when filled with liquid; said upper body (61) having a rib (65) containing the center of gravity; said rib (65) being not adapted to absorb a negative pressure in the container; at least one surface of said lower body including a vacuum panel (66, 67).

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a large bottle-shaped container having a substantially rectangular cross section. More particularly, the present invention relates to a bottle-shaped container that does not need to absorb a reduced internal pressure in the container by a grip thereof and that has a improved rigidity for the entire container. [0003] 2. Related Background Art [0004] So-called 64-ounce containers (having a weight capacity of about 1.8 kg and a volume capacity of about 1.8 liters) and other large containers (bottles) in the U. S. market show a shift from those having a substantially circular cross section to those having a substantially rectangular cross section, from a viewpoint of easy handling on a route of delivery and in a shop. [0005] U.S. Pat. No. 6,575,321 discloses a bottle-shaped container having a neck, a body portion including a top portion and a bottom portion, and a bottom. The body portion of th...

AI Technical Summary

Benefits of technology

[0008] In view of the above described circumstances, it is therefore an object of the present invention to provide a large bottle-shaped container having a substantially rectangular cross section, which container shows an improved property for absorbing a reduced internal pressure by the lower body, and does not need to absorb the reduced internal pressure by the grip thereof while showing an improved rigidity as a whole.

[0019] According to the invention, it is not necessary to provide a grip capable of absorbing the reduced internal press , at a portion (waist section or circumferential rib of the present invention) containing a center of gravity of the container when filled with liquid, so as to easily the container with high rigidity.

[0020] Additionally according to the invention, the container has a vacuum panel showing a large area, so that all the negative pressure generated in the container is absorbed by the lower body, and the grip and the upper body are not affected by negative pressure to improve the rigidity of the bottle.

[0021] Finally, the container according to the invention shows an improved resilience particularly at the panel by forming a transversal rib in the vacuum panel, so that it is possible to prevent permanent deformation from taking place.

Problems solved by technology

Meanwhile, it is sometimes impossible for a large bottles to absorb a reduced internal pressure in the bottle only by means of vacuum panels of the bottom portion.

Then, there arises a risk that the grip is permanently deformed and that an appearance of the bottle is damaged as a result of permanent deformation.

Still additionally, since the vacuum panels inevitably show a large total surface area (particularly when a further vacuum panel is formed in the top portion in addition to the vacuum panel formed in the grip), such a large total surface area of the vacuum panels by turn restricts a design freedom of the bottle.
