POSITIVE-PRESSURE CAN

WIPO Patent Application WO/2019/151281

A1

Provided is a positive-pressure can in which the restoration sound of a polyhedral wall is increased and which imparts an auditory effect at the same time as the visual effect of a unit panel being restored, or a positive-pressure can in which it is possible to reduce the restoration sound to an extent that the same can be ignored. The maximum value of a maximum depth change quantity of a unit panel is set within the range of 0.75-1.2 mm, or the average value of the maximum depth change quantity for the unit panel for which the maximum depth change quantity is 0.4 mm or greater is set within the range of 0.54-0.75 mm. In addition, the average value of the maximum depth change quantity of each unit panel is set within the range of 0.46-1.08 mm, the unit panel being such that the cross-sectional shape in a direction parallel to the center axis of a can barrel is depressed in a circular arc toward the inner side of the can barrel in a free state in which no internal pressure is added. In addition, the maximum value of the maximum depth change quantity of the unit panel is configured to be 0.54 mm or less, or the average value of the maximum depth change quantity for the unit panel for which the maximum value of the maximum depth change quantity is 0.4 mm or greater is configured to be 0.45 mm or less.
