CAP STRUCTURE HAVING A PLURALITY OF BREACH HOLE FEATURES AND ZIPPER HEAD ASSEMBLY STRUCTURE USING THE SAME

摘要

A cap structure includes a cap body and an elastic piece. The cap body has at least two first inner concave grooves corresponding to each other, at least two first retaining blocks corresponding to each other and respectively extended outwardly from the at least two first inner concave grooves, and at least two first through holes corresponding to each other and respectively adjacent to the at least two first retaining blocks. The at least two first inner concave grooves are disposed on the inner surface of the cap body, and the at least two first through holes pass through the cap body to form two breach holes between the inner and the outer surfaces of the cap body. The elastic piece is disposed on the inner surface of the cap body, and the at least two first retaining blocks contact the elastic piece for retaining the elastic piece.
