Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an apparatus for manufacturing caps for containers such as bottles. BACKGROUND ART Conventionally, a cap as shown in Fig. 15 has been widely used. Since this invention relates to an apparatus for manufacturing the type of cap shown in the figure, the conventionally used cap described above will first be explained. In the figure, reference numeral 1 denotes a mounting part for attaching the middle cylinder 25 and the inner cylinder 26, and the part 1 is used to attach the bottle to the mouth of the bottle (not shown). 2 is a partition that blocks the flow of liquid; 3 is an endless fissure; 4
numeral 5 is a torn part formed at the inward opening of the same fissure, and 5 is a pot.
Further, 6 is a tearing member such as an al ring, and 7 is a synthetic resin inner stopper having the above-mentioned parts. The inner stopper 7 is made of polyethylene or the like, for example. Next, reference numeral 12 denotes an outer cover made of synthetic resin, such as polypropylene, which is composed of a cylindrical portion 9 and a II body 11 integrally provided with the cylindrical portion 9 via a bent portion 10.
Further, the cylindrical portion 9 is pressed against the middle cylinder 25 by a protrusion 27 formed inside the cylindrical portion 9. Although the protrusion 27 is shown inserted into the inner cylinder 25, this is due to the difficulty of illustration; in reality, it is pressed into contact with the inner cylinder 25. In the figure, 28 indicates a bottle, and 29 indicates a liquid product inside the bottle 28. The consumer or the like opens the lid l1, pulls the tearing member 6 in the direction of arrow A6, tears the fissure groove 3 to form an opening, and pours out the liquid product 29 contained in the bottle for use. This type of cab is used as a prize because it is sealed until it is first opened. Problems to be Solved by the Invention However, the above-mentioned conventional caps had the following problems. This is done manually when attaching the outer cover 12 to the inner stopper 7, which does not improve work efficiency. Outer lid 212, inner plug 7
Once molded, a large number of them are packed in bags and stored in a warehouse, etc. From this warehouse, the amount required for the work is transported to an assembly workshop, where assembly is performed. And at that time. When we looked at the outer lid 112, which had been packed in a bag, we found that the outer lid 112 was stacked on the bottom. 112, etc., the bent portion 10 is bent due to the outer lid 12 facing upward,
The lid is twisted, and simply rotating the lid l1 in the closing direction does not allow it to fit properly and will not close. As a result, work efficiency does not improve. In addition, it requires troublesome transportation work to take it in and out of warehouses, etc., and it also requires auxiliary materials such as bags. This invention was made in order to solve the various problems mentioned above, and its purpose is to enable efficient manufacturing without tedious manual work, and to eliminate the need for bent parts even though they are stacked on the bottom due to bagging, etc. It is possible to eliminate the difficulty of closing the lid body 11 due to twisting of the IO, and it is possible to omit the troublesome effort of carrying in and out of a warehouse etc.
Supplementary materials for transport, storage, etc. can be omitted.
