もあった。Problems to be Solved and Attempted by the Invention In conventional plastic containers for infusions, after the molding is completed, the hanging ring is bent and the hanging hole is engaged with a protrusion provided at the bottom of the container body. Since it was designed to be bent and locked at the bottom, the hanging ring goes over the undercut part of the protrusion to lock it, so the undercut part deforms or caves in, making it impossible to lock it completely. Something happened. There is also a problem that the shape of the locking protrusion varies due to molding, and the locking state changes, resulting in a lack of reliability.

When locking the hanging ring, the locking protrusion will not deform, cave in, or slip off, making it possible to achieve complete locking and fixing.Also, the locking of the stepped part and the hanging ring will be free from variations due to molding. The purpose of the present invention is to provide a method for manufacturing a plastic container for infusions that can be carried out independently of the process and that can improve the reliability of retention and fixation. A container main body having a bottom with a stepped portion is formed by erecting a hanging ring on the bottom of the container body so that it can be easily bent from the base, and having a protrusion that faces the stepped portion in the folded state on the side surface. Then, the protrusion of the suspension ring is heated and softened, and then bent, and the protrusion is pressed against the stepped portion to deform and fix the protrusion and the stepped portion.
実施例
本発明の実施例を第１図から第５図に基づいて説明する

アンダカット状にさらに低くシ九段部８が設けである。In the figure, reference numeral 1 indicates a container body of a plastic container for infusions made of thermoplastic synthetic resin by blow molding. A recess 5 is provided in the portion. And this recess 5
A hanging ring 7 having a hanging ring 7 is erected in the center thereof so that it can be easily bent from its base. The width of the recess 5 is such that the folded hanging tomb 7 can be completely inserted therein. Further, the recess 5 is provided with a nine-step portion 8 that is lower than the bottom surface of the recess 5 in an undercut shape.

。In order to bend the above-mentioned hanging ring 7 and fix it to the step part 8,
The tip of the protrusion 9 of the hanging ring 7 in the upright state (Fig. 2) is heated and softened to around the melting point using heating means such as a hot plate, hot air, infrared rays, and far infrared rays, and then the hanging ring 7 is bent (
3 and 4), this protrusion 9 is pressed against the stepped portion 8.
かくすると、突起９は段部８のアンダカット部の形状に
沿った形状に変形（第４図）し、段部８に突起９が係合
固着される。As a result, the projection 9 is deformed into a shape that follows the shape of the undercut portion of the stepped portion 8 (FIG. 4), and the projection 9 is engaged and fixed to the stepped portion 8.

突起９が段部８と溶着されるので固着が確実で効率良く
できる。The thermoplastic synthetic resin to be used can be one that can be blow molded, but if it is a thermoplastic synthetic resin that has weldability such as polyethylene or polypropylene,
Since the protrusion 9 is welded to the stepped portion 8, the fixation can be performed reliably and efficiently.
