[0013] The opening tab 1 of the can, which is a beverage can, a food can, and other use cans according to the present invention, is made of a material, a size, an outer shape, a size and a shape of the rivet 2, and an opening to the can top cover 10. It is not necessary to change the joining method and joining position of the tabs, and the material, thickness, and shape of the can upper surface cover portion 10, the can body 12, the can bottom concave portion 14, and the can bottom joint portion 15. In addition, the method and means of opening are not different from the conventional method. It is formed by improving only an arbitrary part of the shape of the opening tab 1.

The present invention will be described with reference to the drawings. FIG. 5 shows a beverage can having a gap 8 into which a fingertip can be inserted by bending a portion close to the tip 3 of the opening tab of the beverage can upward according to the present invention. It is a longitudinal cross-sectional view of an upper half. FIG. 6 is a vertical sectional view of the upper half of the beverage can in which a portion near the central portion 11 of the opening tab of the beverage can is bent upward to form a gap 8 into which a fingertip can be inserted according to the present invention. . FIG. 7 is a vertical sectional view of the upper half of the beverage can in which a portion near the rivet fixing portion 17 of the opening tab of the beverage can is bent upward according to the present invention to form a gap 8 into which a fingertip can be inserted. FIG. 8 is a longitudinal sectional view of the upper half of the can having a gap 8 into which a fingertip can be inserted by bending a portion of the can close to the tip 3 of the opening tab upward according to the present invention. FIG. 9 is a vertical cross-sectional view of the upper half of the can having a gap 8 into which a fingertip can be inserted by bending a portion close to the central portion 11 of the opening tab of the can according to the present invention upward. FIG. 10 is a vertical cross-sectional view of the upper half of a food can in which a portion close to the rivet fixing portion 17 of the opening tab of the food can is bent upward according to the present invention to form a gap 8 into which a fingertip can be inserted. FIG. 11 is an example in which the opening tab 1 is bent upward in a curved shape according to the present invention. FIG. 4 is a longitudinal sectional view of the upper half of the food can in which a gap 8 into which a fingertip can be inserted is formed by bending a tip 3 of an opening tab of the food can upwardly in a curved shape.

The height of the tip 3 of the opening tab bent upward is equal to or less than the height of the upper limit 9 of the joining portion above the can body.

According to the present invention, an arbitrary part of the opening tab 1 of a beverage can or a food can is bent upward linearly or curvedly as shown in FIGS. A gap 8 is formed between the opening tab 1 and the top surface 10 of the can, and a fingertip is inserted into the gap 8 and the opening tab 1 is pulled upward with the fingertip to improve the opening tab 1 to facilitate opening. It is. The shape and size of the opening tab of other use cans are different from those of beverage cans and food cans. However, the structure in which the opening tab 1 is closely adhered to the top cover 10 of the can and horizontally is a beverage can. The same effect can be obtained by applying the improvement of the opening tab 1 according to the present invention similarly to the case of the food can.

In the conventional beverage can, a recess 7 is formed in the top lid 10 of the can that contacts the tip 3 of the opening tab. The recess 7 is extremely small and shallow, and a fingertip is inserted instead of a toe. Do not stand. The presence or absence of the recess 7 of the food can and other container cans varies.
