PLASTIC BOTTLE BODY AND COMBINATION OF SUSTAINED USE CONTAINER AND REFILL CONTAINER

Document Type and Number:

WIPO Patent Application WO/2011/078078

Kind Code:

A1

Abstract:

Disclosed is a shape of a plastic bottle body that is created to allow smoothly reducing waste volume of the circumferential wall in accordance with decompression upon the interior thereof while maintaining a stable posture; and deriving both a stable operation of refilling of fluid content, and a desirable state of disposal for a refill container, as relates to a combination of a sustained use container, comprising an upright spout cylinder part, and the refill container. The bottle body is configured such that the circumferential wall of the torso portion is formed thinly, allowing the reduction of waste volume thereof in accordance with decompression upon the interior of the bottle body, the circumferential wall further comprises three ridgelines that are formed equidistantly in mountain fold shapes in the vertical direction, and adjacent ridgelines are joined by three panel walls. Each panel wall is formed such that a valley fold crease line is formed thereupon that diagonally links the uppermost portion of one ridgeline with the lowermost portion of another ridgeline, and that the three crease lines incline in parallel in the circumferential direction.
