PROBLEM TO BE SOLVED: To provide a can cap capable of being mounted on some of the outer edges of the drinking port side of beverage cans of different diameters.SOLUTION: A can cap 1 comprises: a first peripheral wall portion 3 and a second peripheral wall portion 4 capable of being mounted on three kinds of first to third beverage cans of different winding-tightening part diameters individually formed with drinking ports and protruding substantially in vertical directions from one face side 21 of a top wall part 2; and a third peripheral wall portion 4 protruding substantially in parallel with the second peripheral wall portion 4 from a diametrically large side 6 formed in a radially widening direction from the vicinity of the tip of the second peripheral wall portion 4. The second peripheral wall portion 4 and a third peripheral wall portion 5 are positioned on the radially wider side than the first peripheral wall part 3. A first fitted part outer surface 31 on the circumferentially inner side of the first peripheral wall part 3 is fitted on the outer side of the winding-tightening portion of the first drinking can. A second fitting part outer face 41 on the inner circumferential side of the second peripheral wall portion 4 is fitted on the outer side of the winding-tightening part of the second beverage can. A third fitting part outer face 51 on the inner circumferential side of the third peripheral wall portion 5 is fitted on the outer side of the winding-tightening part of the third beverage can.SELECTED DRAWING: Figure 2 |
