魔にならないようになつている。Conventional technology This type of conventional plastic container for infusion is the fifth type.
It was as shown in Figure 6. This conventional example is known from Japanese Utility Model Application Publication No. 57-45944, in which a recess b is provided in the center of a seat part a, and a hanging ring c is bent and erected in this recess b. There is. The recess b is provided with a protruding holding protrusion e that engages with the hanging hole d of the bent hanging ring c, and when the container is made to stand on its own, the hanging ring c must be bent as shown in Fig. 6. The hanging hole d of this is engaged and held by the holding convex part e so that the hanging ring c does not get in the way of self-supporting.

れていた。Problems to be Solved by the Invention Since the above-mentioned hanging ring c is installed upright on the parting line of the container to be hollow-molded, in the case of a conventional plastic container for infusion, the above-mentioned hanging ring c has a hanging hole d. A holding convex portion e that engages with and holds the hanging ring c in a bent state is protruded from a parting line as far as the hole d of the hanging ring c.

できなくなつてしまうという問題があつた。 For this reason, when the container is molded by blow molding, the wall thickness of the holding protrusion e becomes extremely thin, and when the holding protrusion e is engaged with the hanging ring c.
There was a problem that the ring could become deformed and become disengaged, making it impossible to perform its original function of holding the hanging ring.
また上記薄肉となつた保持用凸部ｅにピンホー

成形がやつかいであつた。 Furthermore, in order to engage and hold the holding convex part e in the hole d of the suspension ring c, the tip of this part had to be formed into an undercut shape, which was difficult to form.

There is no need to worry about pinholes forming in the area that engages with the ring.
Furthermore, the object of the present invention is to provide a plastic container for infusion in which the engagement part with the hanging ring can be easily molded without undercutting, and the structure includes a seat part that can stand on its own, etc. In a plastic container for infusions, a recess is provided at the bottom of the container, and a bendable hanging ring is placed upright in the recess via a thin-walled hinge. A thin plate portion that is deformable is formed, and a stepped portion is formed in the recessed portion in the bending direction of the hanging ring so as to interfere with the thin plate portion.

保持される。Function When the container stands on its own, the hanging ring is bent and stored in the recess, and at this time, the thin plate formed on the edge of the hanging ring interferes with the stepped part of the recess and is deformed.
The deforming force at this time holds the hanging ring in a bent state.
実施例
本発明の実施例を第１図から第４図に基づいて

８，８が設けてある。 In the seat part 2, a recess 5 is provided in the center of the approximately elliptical seat surface in the direction of the short axis.
A hanging ring 6 extending along the parting line L is erected so as to be bendable to both sides in the short axis direction via a thin hinge 6a. Suspension ring 6 has suspension hole 7
Also, on both sides of the hanging ring 6, thin plate parts 8, 8 are provided which are thinner than other parts and can be deformed to a different thickness.

壁に設けられている。 The recess 5 has a depth that allows the hanging ring 6 to be bent and stored therein, and on both side walls of the recess 5 there are upper and lower protrusions 9, 9 that interfere with the thin plate parts 8, 8 of the bent hanging ring 6. It is set in the direction. The protrusions 9, 9 are provided on the side walls of the recess on both sides of the hanging ring 6 in the bending direction.

先端の肉厚は0.3mmである。 The plate thickness t1 of the hanging ring 6 is 2 to 3 mm, and the thin plate part 8
The appropriate wall thickness t 2 is 0.1 to 0.5 mm, and in this embodiment, t 1 =2.5 mm, t 2 =0.4 mm, and the wall thickness at the tip of the protrusion 9 is 0.3 mm.

る。 In the above configuration, when the hanging ring 6 is bent,
The thin plate parts 8, 8 provided on both side edges of the hanging ring 6 interfere with the protrusions 9, 9 of the recessed part 2 and deform in the plate thickness direction (Fig. 4), and the deforming force at this time causes the hanging ring 6 to deform.
is held in a folded position. In this state, container 1
can stand on the seat part 2 without the hanging ring 6 getting in the way. When using the container 1 in a suspended manner, the hanging ring 6 is raised against engagement with the protrusions 9, 9,
Hang it from the hanging hole on the stand. In this state, a lead-out needle is inserted into the mouth 4 to begin dripping.
なお上記実施例では吊り環６の両側に薄肉板部
８，８を設けた例を示したが、この薄肉板部８は
吊り環６の一側縁だけに設け、従つてこれに干渉

してもよい。 In the above embodiment, the thin plate portions 8, 8 are provided on both sides of the hanging ring 6, but the thin plate portion 8 is provided only on one side edge of the hanging ring 6, and therefore there is no protrusion that interferes with the thin plate portion 8. The strip 9 may also be provided only on one side of the recess 5.
また、凹部５の形状は、上記実施例のように突

る。Effects of the Invention According to the present invention, even if the stepped portion for locking the hanging ring 6 in a bent state is located away from the parting line of the container 1, the wall thickness of this portion can be increased by blow molding. Therefore, the holding strength of this stepped portion can be increased, and the engagement with the hanging ring 8 can be performed firmly. Also, since this part is thick, there is no need to worry about pinholes forming. Furthermore, since the stepped portion does not have a shape that causes an undercut, the stepped portion can be easily molded.
