Document Type and Number:
Japanese Patent JP2019218128
Kind Code:
A
Abstract:
To provide a bottle can that is a so-called "sloping shoulder" shaped bottle can extending from a cylindrical part at a small angle of inclination and that is not easily deformed even if colliding during transport.SOLUTION: A bottle can has a cylindrical part, a concave-convex shoulder part in which the diameter is gradually reduced from an upper end part of the cylindrical part toward an upper side of a can axis and a groove-shaped concave part is formed at interval in a circumferential direction, a reduced diameter part having a truncated conical outer surface formed at the upper end of the concave-convex shoulder part and gradually reduced in diameter in a direction of the can axis, and a mouth part formed at the upper end of the reduced diameter part, a concave part in the concave-convex shoulder part is provided to be inclined with respect to the can axis, a bottom of the concave part is formed in a linear or a circular arc shape, or a shape combining the linear and a circular arc whose inclination angle with respect to the can axis is smaller than an inclination angle of the reduced diameter part in a longitudinal section through the can axis.SELECTED DRAWING: Figure 1
