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

The present invention provides a large bottle-shaped container with improved properties for absorbing reduced internal pressure by the lower body, while not needing to absorb the reduced pressure by the grip. The container has a vacuum panel with at least one transversal rib that acts as a grip and prevents permanent deformation from taking place. The vacuum panel has a large area that absorbs all the negative pressure generated in the container, improving rigidity and preventing the grip and upper body from being affected by negative pressure. The container is made of synthetic resin and has a neck and body with an upper body containing the center of gravity and a waist section with a grip. The grip is not adapted to absorb a negative pressure in the container. The lower body has at least one surface including a vacuum panel that helps absorb the negative pressure. The container is easy to handle with high rigidity and resilience.

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.
