Embodiment ）

[0059] Next, according to the difference in inclination angle θ of the erected peripheral wall portion 121 , an embodiment of experiment (analysis) of how the upper end portion of the erected peripheral wall portion 121 changes in the radial direction of the bottle when the contents are filled will be described.

[0060] In this test, the following four model tests were carried out as an example. Furthermore, the following four model tests were performed as a comparative example of an example. That is, a total of eight models were tested separately. In addition, in this test, the height (when the bottle is empty) from the ground surface to the uppermost part of the curved surface 125 was 7.7 mm.

[0061] As an example, four models of 1.5 degrees, 3 degrees, 4.5 degrees, and 9 degrees were used for the inclination angle θ of the standing peripheral wall portion 121 . In contrast, as a comparative example, four models of 12 degrees, 15 degrees, 20 degrees, and 30 degrees were ...

Abstract

The bottle of the present invention is a bottomed cylindrical bottle formed of a synthetic resin material, and the bottom wall portion of the bottom is provided with: a grounding portion located at the outer peripheral portion; Connected and extend upwards; an annular movable wall part protrudes from the upper end of the erected peripheral wall part toward the inner side of the bottle radially; and a concave peripheral wall part is connected with the movable wall part from the radially inner side of the bottle , and extend upwards. The movable wall portion is arranged to be rotatable about a connection portion with the upright peripheral wall portion so as to move the concave peripheral wall portion upward. The standing peripheral wall portion extends from the ground portion to the connection portion with the movable wall portion so as to gradually incline toward the inner side of the bottle radial direction, and the inclination angle thereof is 10 degrees or less with respect to the bottle axis. .

Description

technical field [0001] The present invention relates to a bottle. [0002] This application claims priority based on Japanese Patent Application No. 2011-163103 for which it applied to Japan on July 26, 2011, and Japanese Patent Application No. 2011-188613 for which it applied to Japan on August 31, 2011, and uses the content here. Background technique [0003] Conventionally, as a bottomed cylindrical bottle made of a synthetic resin material, for example, the structure of the bottle shown in the following patent document 1 is known. Patent Document 1 discloses a structure in which the bottom wall portion of the bottom is provided with: a grounding portion positioned at the outer peripheral portion; an upright peripheral wall portion connected to the grounding portion from the inner side in the radial direction of the bottle and extending upward; a movable wall part, protruding from the upper end of the erected peripheral wall part toward the inner side of the bottle radia...
