Abstract

PROBLEM TO BE SOLVED: To impart a braille to the outside surface of a peripheral wall of a can body of a two-piece metallic can at a low cost without requiring costly equipment with an extremely simple work by forming the braille in accordance with the printing of foamed ink to the outside surface of the peripheral wall of the can body for metallic can, such as a two-piece aluminum can. SOLUTION: The outside surface of the peripheral wall 2 of a can body 1 with a braille for two-piece metallic can is provided with the braille 8 formed by thermally expanding the characters printed by using a foamed ink. When the braille 8 is transparent, plural printed part regions of different colors are formed on the outside surface of the peripheral wall 2 of the can body 1 by using a plurality of colored ink, by which the can body is provided with the transparent braille 8 across the plural printed part regions. The braille 8 is disposed on the outside surface of the intermediate smooth parts 4 between annular projecting parts 6 and 7 at both top and bottom ends of the outside surface of the peripheral wall 2 of the can body 1 of the two-piece metallic can.

2. Description of the Related Art In the past, it has been widely practiced to put Braille on a can lid of a two-piece metal can, but conventionally, Braille was formed on a can lid by engraving with a die. It is also known to apply braille to the can body of a two-piece metal can. Conventionally, a method of engraving Braille on the can body peripheral wall by sandwiching and rotating the can body peripheral wall with two uneven rolls has been proposed. Have been. On the other hand, transparent braille stickers that can be attached to the outer surface of the container are already commercially available.

However, according to the conventional method of providing Braille on the can lid of a two-piece metal can, the cost of the mold is extremely high, and the area of the can lid is small, so that the number of prints is limited. If the display in braille is changed for each content of the metal can, it is necessary to use different lots of can lids for each type, which is very troublesome and time-consuming There was a problem. In addition, according to the conventional method of using two uneven rolls for braille on the can body of a two-piece metal can, there is no restriction on the number of prints, but the equipment and roll costs for engraving are very high. was there. Further, when a conventional braille seal is used to apply braille to a can body of, for example, a two-piece metal can, it is very troublesome to attach the braille seal to a predetermined position on the outer surface of the can body, and the cost of the braille seal is high. However, there is a problem that the manufacturing cost of the braided can body of a two-piece metal can is increased.

When a plurality of printing areas such as images and graphics are formed, transparent braille can be provided over the plurality of printing areas, and even if such transparent braille exists, the lower braille This is convenient because the printed portion made of the colored ink is directly shown. Moreover, by providing Braille on the outer surface of the peripheral wall of the can body, there is an effect that it is possible for a blind person to recognize the contents such as beverages and the manufacturer of the two-piece metal can.

The braille is provided on the outer surface of the intermediate smooth portion between the annular projections at the upper and lower ends of the outer peripheral surface of the can body peripheral wall of the two-piece metal can. In the process of film packaging and transport,
This brings about an effect that it is possible to effectively prevent the braille from collapsing due to the contact between the piece metal cans.

Further, according to the method of manufacturing a can body with braille of a two-piece metal can according to the present invention, a braille character is printed on the outer surface of the can wall of the two-piece metal can with foaming ink, and then the entire outer surface of the can wall is protected. The varnish is applied and then heated to expand the braille characters of the foamed ink to form braille. According to the method of the present invention, the foamed ink is printed on the outer surface of the peripheral wall of the can body of a two-piece metal can. Braille can be formed by a very simple operation based on the equipment cost and roll cost for engraving such as to apply Braille on the can body of a two-piece metal can using two conventional uneven rolls. Without the need for
In addition, it is not necessary to use a conventional braille seal, and it is possible to minimize the cost increase due to the application of braille to a two-piece metal can, and to apply braille to the outer peripheral surface of the can body of a two-piece metal can at low cost. This has the effect that it can be performed.
