Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plastic container that can be disposed of in a folded state after use by reducing the volume thereof.
[0002]
[Prior art]
A bottle-shaped plastic container such as an infusion solution container is described in Japanese Patent Application Laid-Open No. 6-218027, and is a bottle-shaped plastic container that can be folded after use or disposed of in a small package. As described above, those described in JP-A-7-52934 or JP-A-10-167242 are known.
[0003]
[Problems to be solved by the invention]
In the plastic container described in the above-mentioned JP-A-7-52934, an engagement ring is integrally provided in the body portion, and the engagement ring is hung on the mouth portion. Since the ring has to be provided with a large hole for hanging on the mouth, there are disadvantages that the engagement piece is large and obstructs use, and that the engagement ring is easily detached from the mouth. Further, the one described in Japanese Patent Application Laid-Open No. 10-167242 has an engagement protrusion formed on a cap that is screwed into a mouth portion, and the engagement protrusion of the cap when the body portion is folded in two. Since it engages with the engaging recess formed on the bottom side of the body portion, there is a disadvantage that the cap cannot be separated and discarded.
[0004]
Accordingly, an object of the present invention is to form a thin weakened portion that can be cut and raised in a tongue piece without breaking the shape of a soft plastic container having a conventionally known hanging tongue piece. An object of the present invention is to provide a plastic container that can be disposed of by disposing the mouth portion of the container folded in half at the cut-and-raised portion of the tongue piece.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a plastic container according to claims 1 and 2. That is, the plastic container according to claim 1 is a soft plastic container having a mouth portion at one end of the body portion and a tongue piece for hanging at the other end, and the body portion can be folded in two. the tongue, hanging hanging hole is formed for lowering, the engaging piece formed by cutting and bending from the outside to the inside further along the periphery being subjected to lower the one side of the tongue piece It is characterized by having a thinned weakened portion of a predetermined length that can be formed.
[0006]
The plastic container according to claim 2 is the plastic container according to claim 1, wherein the locking piece is a bowl-like shape that is formed in a substantially bowl-like shape that can lock the leading end of the cut and raised portion to the opening of the mouth. part and having a corresponding hook receiving portion and is characterized in Rukoto.

DETAILED DESCRIPTION OF THE INVENTION
In the drawings, a plastic container according to the present invention for infusion is illustrated upside down. FIG. 1 is a front view of a plastic container according to an embodiment of the present invention, FIG. 2 is a side view of the same, and FIG. 1 (a) is a side view showing a state before a body part is folded in two, and FIG. FIG. 3 is a detailed view of a part of the plastic container shown in FIG. 1, and FIG. 3 (a) shows the state before the locking piece is raised from the tongue piece. A front view and (b) are front views which show the aspect which cut and raised the latching piece from the tongue piece, and was bent in one direction.
[0008]
1 is a plastic container. The plastic container 1 is composed of a body part 2, a neck part 3, and a mouth part 4. A tongue piece 5 is formed in a series on the bottom part of the body part 2, and the tongue piece 5 has a suspension hole 6 for hanging. Is formed.
[0009]
The plastic container 1 is integrally molded by blow-molding a thermoplastic plastic, and its body part 2 is thin and flat, as shown in FIG. Can be folded in half in the top and bottom half. Although not shown, if a folding line for assisting in folding is provided in a substantially half of the upper and lower portions of the body portion 2, the body portion 2 can be easily and reliably folded in half.
[0010]
The tongue piece 5 formed in series at the bottom of the body portion 2 is provided with a locking piece portion 7 ′ for folding the body portion 2 in half and locking it to the mouth portion 4. This locking piece portion 7 'is formed in a shape extending from one side of the tongue piece 5 to the lower side, and is integrally formed with the tongue piece 5 via a thinned weakened portion 8 that can be entirely torn off. When the locking piece 7 is cut and raised so as to tear the thinned weakened portion 8, the base end of the locking piece 7 is connected to the tongue piece 5 via the thin hinge portion 9.
[0011]
The locking piece 7 for folding the body part 2 in half and locking it to the opening part of the mouth part 4 has a substantially hook-like part 10 whose tip part is locked to the mouth part 4. A hook receiving part 11 corresponding to a substantially hook-like part 10 showing a trace after the locking piece 7 is cut and raised is formed.
[0012]
The locking piece 7 for folding the body part in half and locking it to the mouth part 4 is a tongue piece so as to first cut off the hook-like part 10 from the hook receiving part 11 of the tongue piece 5 and tear off the thinned weakened part 8. If it cuts and raises from 5, as shown to (b) from the state of (a) of FIG. 3, the locking piece 7 which can be bent in arbitrary directions can be formed via the hinge part 9 of the base end. The hook-shaped portion 10 of the locking piece 7 is configured to be securely locked and held by inserting the tip of the locking piece 7 into the opening of the mouth portion 4 as shown in FIG. ing.
[0013]
The plastic container 1 according to the present invention has a locking piece 7 which is cut and raised from the tongue piece 5 by folding the body part 2 in half as shown in FIG. 2 (b) from the state shown in FIG. The direction is changed by twisting and bending through the hinge portion 9 at the base end so that the mouth portion 4 can be easily hung. Then, the distal end of the locking piece 7 is inserted into the opening of the mouth portion 4, and the hook-shaped portion 10 is locked to the mouth portion 4.
[0014]
Thus, by keeping the body part 2 in a folded state, the plastic container 1 after use can be disposed of with a small volume.
[0015]
【The invention's effect】
As described above, the plastic container of the present invention has a structure in which a part of the hanging tongue piece can be cut and raised to form a locking piece part without breaking the conventional container shape. It can be easily maintained in a small volume state in which the volume of the two folds is reduced, the conveyance efficiency is good, and it can be manufactured at a low cost. Moreover, it can be reused as a resource after use, and has an excellent effect that it can be incinerated as usual.
