Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite container composed of a soft sealed bag made of synthetic resin or the like and a hard paper carton covering the sealed bag, and more particularly to a composite container which can be stacked in a large number.

[0002]

2. Description of the Related Art Conventionally, a soft sealed bag made of synthetic resin has been used to store fluid contents such as liquids, granules and powders.

Such a sealed bag is required to have a sealing property for preventing leakage, a water vapor barrier property and a gas barrier property for maintaining the quality of the contents, and is made of a soft material as a whole.

[0004]

As described above, a soft sealed bag made of synthetic resin is used to store fluid contents. It is necessary to stack a large number of such sealed bags before shipping or when they are sold at a store, but since they are made of a soft material, the shape retention is poor and stacking is difficult.

The present invention has been made in consideration of such points, and it is possible to stack a large number of layers and to secure the sealing property, the water vapor barrier property and the gas barrier property when the contents are stored. An object is to provide a composite container that can be manufactured.

[0006]

According to the present invention, there is provided a soft sealed bag for storing contents, which has an opening which can be opened and closed on one side and which is closed on the other side, and a box-shaped hard bag which covers at least the other side portion of the sealed bag. It is a composite container consisting of a paper carton.

[0007]

According to the present invention, the contents are housed and sealed in the soft hermetically sealed bag, so that the hermeticity can be secured and the leakage of the contents and the invasion of water vapor, oxygen and the like can be prevented.
In use, the contents can be removed from within the sealed bag using the opening on one side of the sealed bag. Also, because the other side of the sealed bag is covered with a box-shaped hard paper carton,
The shape retention of the entire composite container can be maintained.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are views showing a first embodiment of a composite container according to the present invention.

As shown in FIGS. 1 and 2, the composite container 10
Is a soft sealed bag 11 having an opening 13 that can be opened and closed on one side.
And a box-type hard paper carton 18 that covers the other side of the sealed bag 11. Of these, the sealed bag 11 has an opening 13 that can be opened and closed on one side and an extension portion 11a outside the opening 13, and is a gusset-shaped soft bag as a whole. A grip portion 12 is formed by punching on the extension portion 11 a of the sealing bag 11. The other side of the sealing bag 11 is hermetically sealed, and the other side portion of the sealing bag 11 is housed in a paper carton 18 having an open upper end.

The material of each of the following parts will be described. The sealing bag 11 is formed by laminating a resin film or a resin film with paper, metal or the like as appropriate. For example, polyethylene (P
E) Single layer, laminated body of oriented polypropylene (OPP) and polyethylene (PE), or oriented polyester (PE)
T) and polyethylene (PE) laminate, oriented polypropylene (OPP), aluminum (Al) and polyethylene (P)
E) laminated body, polyester (PET), silica vapor deposition polyester (SiOx / PET), and polyethylene (P)
The laminated body of E) has a water vapor barrier property, a gas barrier property, and a sealing property as a whole. On the other hand, the paper carton 18 is made of coated cardboard, is hard as a whole, and maintains shape retention.

As shown in FIG. 2, the opening 13 of the sealing bag 11 is provided with a chuck member having a projection 13a and a fitting portion 13b which fits the projection 13a along the longitudinal direction of the opening 13. The projection 13a is fitted into the fitting portion 13b to close the opening 13.

Next, the operation of this embodiment having such a configuration will be described.

First, the other side portion of the sealed bag 11 is housed in the paper carton 18 having an open upper end, and the outer surface of the sealed bag 11 is spotted on the inner surface of the paper carton 18 by an adhesive material (not shown). Thus, the composite container 10 is obtained.
Although the contents are stored in advance in the sealed bag 11, it is preferable that the contents be stored with a margin so as to leave a gap above the sealed bag 11. Then, after the contents are filled, the opening 13 is closed.

The composite container 10 thus formed
Are stacked, stored, and transported. In this case, as described above, since the contents are stored in the sealed bag 11 with a margin so as to leave a gap in the upper part, the upper part of the sealed bag 11 is crushed by the paper carton 18 of the composite container 10 located above. , Composite container 1 located below
The upper end 18a of the paper carton 18 of 0 contacts the bottom of the paper carton 18 of the composite container 10 located above. In this way, a large number of composite containers 10 can be stably stacked.

In use, one composite container 10 is taken out of a number of stacked composite containers 10. In this case, the composite container 10 can be taken out by gripping the grip portion 12 of the sealed bag 11 and lifting it up. Next, in the opening 13 of the sealing bag 11, the protrusion 13a is fitted into the fitting portion 1.
The opening 13 is opened by removing it from 3b, and the contents are taken out from the opening 13 for use. After the use, the sealed bag 11 is pulled out from the paper carton 18, and the paper carton 18 made of paper and the sealed bag 11 made of synthetic resin are separately discarded.

Next, a second embodiment of the composite container will be described with reference to FIG. The second embodiment shown in FIG. 3 is provided with an upper surface 20 which extends upward from one side surface of the paper carton 18 and covers the upper end opening of the paper carton 18, and the other is the first embodiment shown in FIGS. 1 and 2. The embodiment is substantially the same as the embodiment. The same parts as those of the first embodiment shown in FIGS. 1 and 2 are designated by the same reference numerals and detailed description thereof will be omitted.

In FIG. 3, an upper surface 20 extends upward from one side surface of the paper carton 18 and is openably and closably provided. The upper surface 20 covers the upper end opening of the paper carton 18 when closed. In addition, a cut 22 is formed on the upper surface 20 so as to penetrate the grip portion 1 of the sealing bag 11 and project outward when the upper surface 20 is closed.
A flapper 21 is provided to be inserted into the inside of the device 8.

According to the embodiment shown in FIG. 3, by closing the upper surface 20 and inserting the flapper 20 into the inside of the paper carton 18, the entire composite container 10 can be formed into a substantially rectangular parallelepiped shape, and a large number of composite containers 10 can be formed. Can be stacked more reliably. Further, in this case, by inserting the grip portion 12 of the sealed container 11 into the cut 22 and projecting it outward, the grip portion 12 can be gripped and the entire composite container 10 can be lifted.

Although the gusset type sealed bag 11 is used in each of the above embodiments, the present invention is not limited to this, and the gusset type sealed bag 11 is not necessary.

Further, in each of the above embodiments, the sealed bag 11 is used.
However, the extension portions 11a formed outside the opening 13 may be welded together by heat sealing or the like as shown in FIG. 4 (FIG. 4 (a)). . By doing so, various barrier properties and sealing properties are further improved. When using, cut section 15
It is opened by cutting (Fig. 4 (b)).

[0021]

As described above, according to the present invention, the contents can be stored in the hermetically sealed bag while ensuring the hermeticity, and the shape retention of the entire composite container is ensured by the hard paper carton. be able to. Furthermore, by separately discarding the sealed bag and the low carton, it is possible to separate and discard.
