状になつている。BACKGROUND ART A conventional plastic container for infusion as described above is disclosed in Japanese Utility Model Application Publication No. 57-45944. In this conventional example, a hanging ring is formed on the bottom of the container body so that it can be easily bent from its base along the parting line, and the hanging ring is attached to the bottom of the container body in a bent state. The hanging ring has a protruding ridge that engages with the hanging hole, and when the plastic container for infusion is completely molded, the hanging ring stands up from the bottom of the container body.

いう問題もあつた。Problems to be Solved by the Invention Conventional plastic containers for infusions, after completion of molding,
The hanging ring was bent and the hanging hole was engaged with a protrusion on the bottom of the container body, and the hanging ring was bent and locked to the bottom of the container body. Since the undercut portion was to be locked by climbing over it, the undercut part was sometimes deformed or caved in, making it impossible to lock it completely. Further, the shape of the locking protrusion varies due to molding, and the locking state changes, resulting in a lack of reliability.

When the hanging ring is locked and fixed, the locking protrusion will not be deformed or caved in, and the locking protrusion will not be deformed or caved in, making it possible to achieve complete engagement and fixation, and the engagement between 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 and improves the reliability of engagement and fixation, and the structure includes a mouth part, a body part,
A container body having a stepped bottom is provided with a hanging ring on the bottom of the container that can be easily bent from the base, and has a protrusion that faces the stepped portion in the folded state. After molding, the protrusions of the suspension ring are heated and softened, and then bent, and the protrusions are pressed against the stepped portions to deform and engage and secure the protrusions and the stepped portions.
実施例

先端側は舌片状の指掛け部７ａとなつている。 In the figure, 1 is a container body of a plastic container for infusions made of thermoplastic synthetic resin by blow molding. This container body 1 has a mouth 2, a body 3 and a bottom 4. A recess 5 is provided in the portion. A hanging ring 7 having a hanging hole 6 is erected in the center of the recess 5 so that it can be easily bent from its base. The width of the recess 5 is such that the bent hanging ring 7 can fit thereinto. Further, the recess 5 is provided with a step 8 which is lower than the bottom surface of the recess 5 in an undercut shape. A protrusion 9 is protruded from the side surface of the tip of the hanging ring 7 at a position corresponding to the step when the hanging ring 7 is bent. Further, the tip end side of this protrusion 9 is a tongue-shaped finger hook portion 7a.

係合固着される。 In order to bend the hanging ring 7 and engage and fix it to the stepped portion 8, the tip of the protrusion 9 of the hanging ring 7 in the upright state (Fig. 2) is heated using a hot plate, hot air, infrared rays, far infrared rays, etc. After heating and softening it to near the melting point using a means, bend the hanging ring 7 (Figures 3 and 4).
Then, press this protrusion 9 against the stepped portion 8. 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.

つてもよい。 When the hanging ring 7 that has been engaged and fixed to the stepped portion 8 as described above is pulled up by holding the finger hook portion 7a, the protrusion 9 is removed from the stepped portion 8 and the hanging ring 7 becomes upright. Hang it by hanging it. Further, as means for engaging and fixing the protrusion 9 and the stepped portion 8, in addition to forming a bulge at the tip of the protrusion 9,
This may be done by changing the protrusion angle of the protrusion 9 itself.

れるので固着が確実で効率良くできる。 Note that the thermoplastic synthetic resin used can be used as long as it can be blow molded, but if it is a thermoplastic synthetic resin that has weldability, such as polyethylene or polypropylene, the protrusion 9 will be welded to the step 8. This allows for reliable and efficient fixation.
