CONTAINER

Japanese Patent JP2018070160

A

PROBLEM TO BE SOLVED: To provide an oval-shaped container having a cross section with high strength against direct axial compression.SOLUTION: A container is formed by synthetic resin, and an opening portion, shoulder portion 20, a barrel portion 30 and a bottom portion 50 are disposed along a center axis J. The shoulder portion, barrel portion and bottom portion are substantially oval-shaped cross-sectional contour perpendicular to the center axis. The shoulder portion has an outer peripheral surface which is a convex surface projecting in a direction in which a distance from the center axis increases in the cross-sectional contour including the center axis. The barrel portion has an outer peripheral surface which is a concave surface connected to the convex surface and hollowing in a direction in which a distance from the center axis decreases in the cross-sectional contour including the center axis. The bottom portion has an outer peripheral surface connected to the concave surface and substantially parallel to the center axis. Relationships c>b>a, and g>h>f are satisfied, where a is a minimum width of the barrel portion, b is a maximum width of the shoulder portion and c is a width of the bottom portion in a long axis direction of the substantially oval-shaped, and f is a minimum width of the barrel portion, h is a maximum width of the shoulder portion and g is a width of the barrel portion in a short axis direction of the substantially oval-shaped.SELECTED DRAWING: Figure 1
