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.

A coating composition including a polyester resin blend as a principal resin, the polyester resin blend containing a polyester resin having a glass transition temperature of higher than 40° C. and an acid value of less than 10 mg KOH/g and (B) a polyester resin having a glass transition. temperature of higher than 40° C. and an acid value of 10 mg KOH/g or more and less than 50 mg KOH/g, and (C) a curing agent. Alternatively, a coating composition containing a polyester resin, as a principal resin, having a glass transition temperature of 60° C. or higher, a resol-type phenol resin. and/or an amino resin as a curing agent, and an organic sulfonic acid-based catalyst and/or a phosphoric acid-based catalyst as a curing catalyst, in which a content of the curing catalyst is less than. 0.2 part by mass per 100 parts by mass of the principal resin. Provided is a coating composition that can manufacture a coated metal sheet and a drawn and ironed can, which have can making processability, substrate adhesion properties, and flavor sorption resistance all together.

Method and installation for manufacturing and inspecting metal containers. The method includes extruding a metal disk to form a metal container having a cylindrical body with a side wall, a base, and an open end opposite the base. After the metal container is formed the thickness of the base is determined by arranging the base between an X-ray emitter and an X-ray receiver and emitting X-rays from the X-ray emitter to the X-ray receiver through the base. The thickness of the base is determined based on the intensity of the X-rays absorbed by the base.

Provided are a seamless can body having excellent pressure resistance and a method for producing the seamless can body. The seamless can body according to the present invention includes a tubular body section (10), a peripheral ground section (20b) continuing from a lower end of the tubular body section, and a raised bottom section (30) continuing from the peripheral ground section toward a center-axis side. When an outer surface area of the raised bottom section is denoted by A.sub.D and an area of a virtual plane an outline of which is formed by the peripheral ground section is denoted by A.sub.B, a relation of 1.55 ≥ (A.sub.D/A.sub.B) ≥ 1.40 is satisfied.

Systems and methods of forming articles using electromagnetic radiation are disclosed. In some aspects, the system includes a plurality of forming modules movably mounted relative to an infeed mechanism. The infeed mechanism is configured to supply pre-form articles to the plurality of forming modules, and each of the plurality of forming modules includes a multi-segment mold disposed about an electromagnetic coil. The electromagnetic coil is configured to impart an electromagnetic force on the pre-form articles when supplied with electrical energy that urges the pre-form articles into contact with the multi-segment mold to produce the formed containers.
