That is, this container has a container body 40 made of a synthetic resin film such as low-density polyethylene in consideration of handling convenience and the like, and the container body 40 is provided with a spout 42. The operator transfers the liquid in the container main body 40 from the plug 42 to another plastic container, and also replenishes and adds to the small container, so that the operator can easily hold the container. The container body 40 has a handle portion 43 having a handle opening 43 formed by cutting out the container body 40 on the opposite side of the spout 42.
It is common that 44 are provided.

[0003]

However, since the container main body 40 is made of a synthetic resin film such as low-density polyethylene, the container main body 40 is inserted by putting a hand into the opening 43 for the support portion of the support portion 44. When lifted, there is a drawback that the peripheral portion of the opening is particularly elongated due to the weight of the liquid.

[0004] Therefore, it is conceivable to embed a gripping pipe in the pallet 44 without providing the pallet opening 43, but in this case, when the container body 40 is folded, the gripping pipe becomes bulky. It may be stretched or in the way.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and it is an object of the present invention to prevent a handle portion formed on a container main body from being inadvertently extended and to stably hold the container main body. It is therefore an object of the present invention to make it possible to easily and surely take out the contents so that the container body does not become bulky when folded.

[0006]

The technical measures taken by the present invention to solve the above problems include flexible sheets 3a and 3b.
Is provided with a handle 13 having a handle opening 15 formed by opening the container body 1 so that the contents can be taken out from the spout 4 of the container body 1. In the container made of a flexible sheet,
Is provided on at least one side thereof, and the reinforcing sheet 17 is provided with a plurality of stretched synthetic resin films 18a,
18b, and the films 18a and 18b are superposed in a direction in which the stretching directions intersect.

Further, the synthetic resin films 18a and 18b of the reinforcing sheet 17 are made of a high density polyethylene film,
Preferably, the flexible sheets 3a and 3b are made of a low-density polyethylene film, and the reinforcing sheet 17 is sealed to the container body 1 by heat sealing.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of the container of the present invention. In FIG.
This is a container body composed of a liquid bag for liters, and the container body 1 is filled with liquid such as commercial shampoo, detergent, sauce, and dressing.

The container body 1 seals the outer peripheral edges 3c of a pair of flexible transparent or translucent rectangular films 3a, 3b (one or two or three laminated films) by heat sealing. It is formed by this. The films 3a, 3b
Is made of a film such as low-density polyethylene and linear low-density polyethylene having excellent heat-fusibility.

One end of one film 3a is provided with a container body 1
A plug 4 communicating with the inside is protruded. The plug 4 includes a plug body 6 having a spout communicating with the inside of the container body 1, and a cap 8 detachably screwed to the plug body 6.

Reference numeral 10 designates a main body 1 as a storage section for storing the liquid.
A partition seal portion for partitioning into the 11 and the fulcrum portion 13, which is band-shaped sealed at the corners of the films 3a, 3b located substantially diagonally to the plug 4. Therefore, the liquid in the storage section 11 does not enter the fulcrum section 13 side. Reference numeral 15 denotes a circular opening for raising the container main body 1, which is formed in the above-mentioned gripping portion 13.

Reference numeral 17 denotes an annular reinforcing sheet provided on one side of the support 13. That is, the reinforcing sheet 17 is composed of two high-density polyethylene films 18a and 18b, and each of the films 18a and 18b is substantially uniaxially stretched, and is superposed in a direction in which the stretching directions are substantially orthogonal. . As the reinforcing sheet 17, a cross-laminated film in which two obliquely stretched high-density polyethylene films are adhered so that the stretching directions are substantially perpendicular to each other is preferable because of its high tensile strength and tear strength. The inner diameter of the reinforcing sheet 17 is formed substantially equal to the diameter of the support opening 15.

The reinforcing sheet 17 is sealed to one of the films 3a of the container body 1 by heat sealing. The sealing portion 20 is provided over the entire circumference of the reinforcing sheet 17, and the peripheral edges 17a on both sides are not sealed. In this manner, by providing the unsealed both side peripheral portions 17a, it is possible to prevent the strength of both peripheral portions of the film from being reduced by the heat of the hot plate (seal bar) or the like when the reinforcing sheet 17 is thermally fused.

When pouring the liquid in the container having the above structure, the cap 8 is rotated to remove it from the plug body 6, and at the same time, the hand is inserted into the handle opening 15 with one hand to make the handle 13 And holding the plug body 6 with the other hand, for example, so that the plug body 6 faces downward.
Is moderately inclined.

The container body 1 is heavy since it is filled with a large amount of liquid, and the load acts on the handle 13 that supports the container body 1 substantially. However, the reinforcing sheet 17 provided on the support portion 13 has two films 18
a, 18b, and since the respective stretching directions are substantially orthogonal, the reinforcing sheet 17 can obtain strength in any direction.

As a result, the films 18a and 18b are unlikely to be stretched in any direction, and the reinforcing sheet 17 is provided in the opening for the support.
Since the seal is integrally formed along the circumferential direction of 15, the peripheral portion of the opening 15 for the buckle is reinforced, and it is not inadvertently stretched, and the buckle 13 is securely and reliably gripped. become able to.

FIG. 4 shows another embodiment of the present invention. In the embodiment shown in FIG. 2A, the shape of the container main body 1 is the same as that described above, but the opening 15 for the hand is formed in a long hole shape, and the entire surface of the reinforcing sheet 17 is Sealed to the container body 1.

In the embodiment shown in FIG. 4 (b), the seal portion 20 forming the pedestal opening 15 has a substantially U-shape.
Both ends are connected to the partition seal section 10. Further, the reinforcing sheet 17 is provided on the entire surface of the handle portion 13 except the opening 15 for the handle, and the peripheral edge thereof is integrally sealed with the outer peripheral edge 3c, the partition seal portion 10, and the seal portion 20.

The present invention is not limited to the above embodiment. The reinforcing sheet 17 is provided on one film 3a of the container body 1, but the other sheet is provided as shown by the phantom line in FIG. 3b may be provided. In addition, the opening for the hand
The shape of 15 can also be set arbitrarily, and this opening is formed in advance as in the above-described embodiment, and after the flexible film 3a, 3b and the reinforcing sheet 17 are overlapped and sealed, the opening is formed. The two films 3a, 3b and the reinforcing sheet 17 may be opened, and a breaking means such as a perforated line is provided in the opening shape. Including the case where

Further, the handle 13 is not limited to one place,
In order to more easily hold the container body 1 as shown by a virtual line,
The container body 1 may be provided above the spigot 4, and the shape of the container body 1 can be freely changed in design. Further, the reinforcing sheet 17 can be composed of three or more films 18a, 18b... When there are three or more films 18a, 18b. Preferably, they are oriented in an intersecting direction.

The contents may be a highly viscous liquid material. In such a case, the reinforcing sheet 17 sufficiently reinforces the handle 13 so that the handle 13 is It is also possible to squeeze the contents below the container body 1 by hooking them on other parts.

[0022]

The container made of the flexible sheet of the present invention comprises:
A reinforcing sheet is provided on at least one side of the support portion, and the reinforcing sheet is formed of a plurality of stretched synthetic resin films, and the films are stacked in a direction in which the stretching directions are substantially orthogonal to each other. Because of the simple structure, the strength of the handle can be sufficiently obtained, and even when the handle of the container body filled with a large amount of contents is lifted, especially the periphery of the opening for the handle of the handle extends. There is almost no risk of doing so. Therefore, the flexible container can be stably held,
The contents can be easily and reliably taken out.

Moreover, since the reinforcing sheet has flexibility, the reinforcing sheet is hardly bulky or obstructed when the container body is folded as compared with the case where a conventional pipe is used. Absent.

Moreover, the synthetic resin film of the reinforcing sheet is made of a high-density polyethylene film, the flexible sheet is made of a low-density polyethylene film, and the reinforcing sheet is sealed to the container body by heat sealing. In this case, the reinforcing sheet can be easily attached to the container body, and the production is simple.
