Abstract
Official abstract text for this publication.
A synthetic resin container that effectively absorbs reduced pressure generated inside the container due to hot filling to maintain the appearance and shape. A synthetic resin container includes a mouth as a dispensing spout for a content medium, a trunk, extending contiguous to the mouth via a shoulder, and a bottom, closing a lower end of the trunk. The trunk is provided with reduced pressure absorbing panels, which are formed as ribs extending in the vertical direction while twisting in the circumferential direction about a central axis of the trunk and which are arranged side by side in the circumferential direction of the trunk. Twist angle of a lower end with respect to an upper end of each reduced pressure absorbing panel about the central axis is 50 degrees or more.
First claim
Opening claim text (preview).
The invention claimed is: 1. A synthetic resin container that absorbs reduced pressure generated inside of the container due to hot filling so as to maintain an appearance and shape of the container, the container comprising a mouth as a dispensing spout for a content medium, a trunk extending contiguous to the mouth via a shoulder, and a bottom closing a lower end of the trunk, wherein the trunk is provided with a plurality of reduced pressure absorbing panels that is formed as a plurality of ribs extending in a vertical direction while twisting in a circumferential direction about a central axis of the trunk and that is arranged side by side in the circumferential direction of the trunk around an entire circumference of the trunk, an angle of the twist of a lower end with respect to an upper end of each of the reduced pressure absorbing panels about the central axis is 50 degrees or more, the reduced pressure absorbing panels each have a width of at least 7 mm and not more than 10 mm in the circumferential direction of the trunk, and each have a depth of at least 2 mm and not more than 3 mm in a radial direction of the trunk, and the trunk is defined by (a) a first annular groove at an upper end of the trunk, the first annular groove extending around the entire circumference of the trunk and (b) a second annular groove at a lower end of the trunk, the second annular groove extending around the entire circumference of the trunk. 2. The synthetic resin container of claim 1 , wherein the angle of the twist is at least 50 degrees and less than 100 degrees.
