Abstract
Official abstract text for this publication.
An aluminum can that has a maximum height of roughness Rz1 in the circumferential direction of not more than 0.5 μm on the outer surface of the thinnest portion of the body portion and, as viewed on the side surface, has a ratio Ra1/Ra2 in a range of 0.8 to 1.2, the ratio Ra1/Ra2 being that of a mean surface roughness Ra1 in the circumferential direction on the outer surface of the thinnest portion of the body portion and a mean surface roughness Ra2 in the circumferential direction on the outer surface of the lower end portion of the body portion.
First claim
Opening claim text (preview).
What is claimed is: 1. An A drawn and ironed aluminum can wherein: an outer surface of the can is not coated with resin; a maximum height of roughness Rz1 as measured in compliance with JIS-B-0601-2001 in a circumferential direction is not more than 0.5 μm on an outer surface of a thinnest portion of a body portion of the can and, as viewed on a side surface of the can, has a ratio Ra1/Ra2 is 0.8 to 1.2, the ratio Ra1/Ra2 being that of a mean surface roughness Ra1 in the circumferential direction on the outer surface of the thinnest portion of the body portion and a mean surface roughness Ra2 in the circumferential direction on the outer surface of a lower end portion of the body portion, and wherein the mean surface roughness values Ra1 and Ra2 in the circumferential direction are measured in compliance with JIS-B-0601-2001.
