Cap structure with elastic turnover cover |
摘要 |
A cap structure having an elastic turnover cover. Body 1 of the cap structure is closed at the top of its first circumferential wall 2 with a cover 5 having a second circumferential wall 7 depending from the outer circumference of its top wall 6 by placing the lower end of the second circumferential wall 7 on the upper end of the first circumferential wall 2. The first and second circumferential walls 2 and 7 have their individual backs connected at their upper and lower ends by a hinge 10. The upper and lower portions of the backs of the first and second circumferential walls 2,7 are so connected through an elastic band 12 that the cover 5 can be opened or closed by the hinge 10. The hinge 10 is integrally molded of a synthetic resin at the back of the elastic band 12. This eliminates notches as a mold parting mark, which might otherwise be left in the cover when the cap structure of this kind is to be integrally molded of a synthetic resin in accordance with the prior art.
