Claims

[Scope of utility model registration request]

(1) In the tab of the pull tab open type lid body, an annular stepped step is formed in the tab main body toward the central through hole, and then descends downward in a concave shape toward the central through hole to reach the upper surface of the opening. A tarp characterized by a structure in which a bottom part of an appropriate width is formed in contact with the outside of the cylindrical part of the rivet, and the rivet is bent upward at the rear to form an annular washer.

(2) In the tab of the pull tab open type lid, an annular stepped step is formed in the tab main body toward the central through hole, and then descends diagonally downward in a concave shape toward the central through hole to reach the opening. The second rivet is characterized by a structure in which the rivet contacts the outside of the cylindrical portion of the rivet, forms a bottom portion of an appropriate width, bends upward at the rear, and bends outward at the bottom of the top to form a double-folded annular washer. Tab described in item 1.

(3) In a pull-open type lid body, an annular stepped step is formed toward the central through hole of the tab body without a slit, and then descends downward toward the central through hole to form an annular step on the upper surface of the opening portion. The tub body is characterized by a structure in which a bottom part of an appropriate width is formed in contact with the tab body, the bottom part is in contact with the outside of the cylindrical part of the rivet, and the tab is bent upward at the rear to form an annular washer, and an arcuate tip is formed in the central part of the tab body. Tab described in Section 1.
