Abstract

Official abstract text for this publication.

Provided is a can with a shoulder portion decorated in a novel way. A can includes: a trunk portion; a mouth portion smaller in diameter than the trunk portion; and a shoulder portion provided between the trunk portion and the mouth portion, gradually decreasing in diameter from the side of the trunk portion toward the side of the mouth portion, and having a printed layer and a coating film respectively formed by printing and coating. The shoulder portion includes: a straight portion having an inclined cross-sectional shape along a can axis C; a lower curved portion that is a curved portion connecting the straight portion and the trunk portion; an upper curved portion that is a curved portion connecting the straight portion and the mouth portion; and an embossed portion provided only in the straight portion among the straight portion, the lower curved portion, and the upper curved portion.

First claim

1 . A can comprising: a cylindrical portion; a small-diameter portion having a diameter smaller than a diameter of the cylindrical portion; and a reduced-diameter portion that is provided between the cylindrical portion and the small-diameter portion, gradually decreases in diameter from a side of the cylindrical portion toward a side of the small-diameter portion, and has a film formed on at least one of an inner surface and an outer surface by printing or coating, wherein the reduced-diameter portion includes an inclined portion having an inclined cross-sectional shape extending through a center axis of the can; a first curved portion that is a curved portion connecting the inclined portion and a can trunk portion; a second curved portion that is a curved portion connecting the inclined portion and the small-diameter portion; and an embossed portion provided only in the inclined portion among the inclined portion, the first curved portion, and the second curved portion. 2 . The can according to claim 1 , wherein the embossed portion is formed at a position away from an outer surface of a connecting portion between the first curved portion and the cylindrical portion by 0.8 mm or more in an inner radial direction, and is formed at a portion away from an outer surface of a connecting portion between the second curved portion and the small-diameter portion by 0.8 mm or more in an outer diameter direction. 3 . The can according to claim 1 , wherein a protruding amount of the embossed portion is 0.3 mm or less. 4 . The can according to claim 1 , wherein a cross-sectional shape orthogonal to the center axis of the can and including the embossed portion of the reduced-diameter portion has an irregularly varying shape, and an installation range of the embossed portion in a circumferential direction in the reduced-diameter portion is a range corresponding to an arc having a center angle θ of 0°<θ≤260°. 5 . The can according to claim 1 , wherein a cross-sectional shape orthogonal to the center axis of the can and including the embossed portion of the reduced-diameter portion has a regularly varying shape, and an installation range of the embossed portion in a circumferential direction in the reduced-diameter portion is a range corresponding to an arc having a center angle θ of 360° or less. 6 . The can according to claim 1 , wherein a maximum outer shape of the embossed portion is greater than or equal to 1.1 mm. 7 . The can according to claim 1 , wherein the protruding amount of the embossed portion is from 0.10 to 0.30 mm, and an inclination angle of a side surface of the embossed portion with respect to the inclined portion is from 9.4° to 25.4°. 8 . The can according to claim 7 , wherein a curved surface forming a ridge line between a top surface of the embossed portion and the side surface of the embossed portion has a curvature radius of from 1.0 to 3.3 mm. 9 . The can according to claim 7 , wherein the side surface of the embossed portion and an outer surface of the inclined portion are connected by a curved surface having a curvature radius of from 0.4 to 2.3 mm. 10 . The can according to claim 7 , wherein in a cross-sectional shape extending through a can axis, a length along the inclined portion between an arc center of the curved surface forming the ridge line between the top surface of the embossed portion and the side surface of the embossed portion and an arc center of a curved surface connecting the side surface of the embossed portion and the inclined portion is from 1.0 to 1.9 mm. 11 . The can according to claim 1 , wherein a center of the installation range of the embossed portion and a front center of the can are aligned. 12 . The can according to claim 1 , wherein the reduced-diameter portion includes a printed portion having a pattern corresponding to a shape of the embossed portion, and an outer shape of the pattern is disposed surrounding an outer shape of the embossed portion, or is disposed inward from the outer shape of the embossed portion. 13 . The can according to claim 1 , wherein the inclined portion is a straight portion having a straight cross-sectional shape. 14 . The can according to claim 1 , wherein the inclined portion is a stepped portion having a shape in which unevenness is repeated in a cross-sectional shape. 15 . The can according to claim 1 , wherein the inclined portion is a curved portion having a cross-sectional shape curved inwardly or outwardly from the can.
