用于存储内容物，抵抗内部压降变形。
专利摘要
本发明的目的是提供一种容器，其真空吸收面板的面积减小，从而获得改善的外观，并且具有抵抗压降的强度，即即使容器内部存在压降也足以保持容器形状的强度。 树脂制存储容器的肩部或底部通过将一组或两组三个角和一组或两组三个柱垂直且平行于容器的中心轴线对齐来模制。每组三个角是形成正九边形横截面并连接到肩部或底部的角的一部分，并且连接这三个角的线形成正三角形。每组三个柱是属于主体并形成六边形横截面的柱的一部分，并且连接这三个柱的线形成正三角形。 如果由于内容物温度降低而导致容器内部压降，则容器主体内部会产生应力，使得主体变形为正三棱柱，垂直对齐的角/柱用作三个角。结果，容器对来自任何方向的力具有增强的强度。由于形状稳定，容器还具有高抗屈曲性。
Original abstractThe object of this invention is to provide a container having a reduced area of vacuum-absorbing panels and thus acquiring improved appearance and having strength against a pressure drop, i.e., the strength enough to retain the shape of the container even when there is a pressure drop inside the container. A shoulder portion or a bottom portion of a resin-made storage container is molded by aligning one or two groups of three corners and one or two groups of three pillars vertically and in parallel to the central axis of the container. Each group of three corners is a part of the corners forming a cross-section of a regular enneagon and being connected to either the shoulder portion or the bottom portion, and the lines connecting these three corners form a regular triangle. Each group of three pillars is a part of the pillars belonging to the body and forming a cross-section of a hexagon, and the lines connecting these three pillars form a regular triangle. If there is a pressure drop inside the container due to a decrease in the temperature of the contents, stress builds up inside the body of the container in such a way that the body deforms into a regular triangular prism, with vertically aligned corners/pillars serving as the three angles. As a result, the container has an enhanced level of strength against the force coming from any direction. With the shape stabilized, the container has also high resistance to buckling.
