Description

[Detailed Description of the Invention] The present invention relates to a composite packaging container in which a solid substance such as a liquid or powder is stored in an inner container made of a synthetic resin film, and the outside is protected by an outer paperboard container such as corrugated paper.

Conventionally, a composite packaging container has been used in which an outer container made of paperboard stores a liquid, etc., a bag made of a resin film is placed inside the bag, and the bag is provided with a spout.

In this type of product, including a spout C attached to the upper part of the synthetic resin film bag body a as shown in Figure 11,
When packaged, the spout C is inside the outer container.
is embedded in or in pressure contact with bag body a, and as the stored liquid moves due to vibrations and shocks during transfer, bag body a may repeatedly bend around spout C, causing fatigue and fatigue. There were drawbacks such as leakage caused by pinholes caused by rubbing against the door.

Also, when taking out the spout C from the outer container, if the bag a is not sufficiently filled with liquid, etc., the position of the spout C will move and the user will have to find the position of the spout C to take out the spout C. This required a lot of effort, such as having to take it out at the same time.

For this reason, only the spout C protrudes outside the outer container to avoid the above-mentioned drawbacks, but when constructed in this way, the spout C protrudes from the surface of the outer container, making it difficult to store or store. There were problems with stacking them in multiple stages or placing them side by side during transportation.

The present invention solves these conventional drawbacks, and the inner container can be easily attached to the outer container, making it easy to store items such as liquids or powders, and even when the items are stored and packaged. To provide a composite packaging container that can be stored or transported in a stacked manner, and furthermore, it is easy to take out stored items, the lid can be reclosed after opening, and it can be used as a daily container.

0.10 and an outer flap 11.11 are attached at positions facing each other inwardly.

The present invention will be explained in more detail with reference to FIGS. 1 to 10 showing an example of implementation of the present invention.

The illustrated products are a frame body 2 and a lid body 5 that constitute an inner container 1.
, the locking ring 7, the synthetic resin film bag body 6, and the outer container 13.

As shown in FIGS. 1, 4, and 5, the frame 2 has a peripheral edge 3a of an opening 3 formed in a ring-shaped frame 2 made of synthetic resin that integrally protrudes downward. A stepped portion 4 was formed on the outer periphery 3b.

The upper edge 3c of the peripheral edge of the frame 2 is formed by descending by the thickness of the side peripheral surface of the lid 5 so that the surface of the lid 5 does not protrude from the upper surface of the frame 2 when the lid 5 is attached. did.

The lid body 5 is made of synthetic resin and formed into a disk shape like the frame body 2. A concentric bead 14 is formed on the center panel surface, so that when the lid body 5 is made of thin soft synthetic resin, the lid body 5 is bent so that it does not become difficult to install.

The bag body 6 is a bag-like body folded in two, the width of the bottom edge 15 is made larger than the diameter of the frame body 2, and the side circumferential surface including the bottom edge 15 is folded along the inner circumferential surface of the bag body 6. A bottom part 8 which can be flattened and expanded by welding integrally with the edge 16 is formed.

To explain in more detail the process of forming the bottom part 8 of the bag body 6, as shown in FIG. The intermediate portion 63 is further folded inward from the fold that forms the bottom edge 15 after the center and is polymerized.

Next, as shown in FIG. 2B, the middle portion 63 is attached to the side portion 62.
At the same time, the intermediate portion 63 and the side portion 62 are welded in a V-shape at both sides.

Then, as shown in FIG. 2C, the middle portion 63 is folded again at 15
After facing each other, the both side edges 16.
Welded together.

When the bag body 6 formed in this manner is expanded, the bottom portion 8 becomes rectangular as shown in the first figure.

In addition, as a modification of the bag body 6 shown in FIGS. 1 and 2, a third
As shown in the figure, a synthetic resin film 61 is folded in half, both side edges 1'6.16□i are welded, and the bag body 6 is expanded, the bottom portion is flattened, and both triangular corner portions 64 are folded back. The lateral surface portion 62 is polymerized.

Therefore, when constructing the inner container 1, the frame 2 is brought into contact with the bottom surface 8 of the bag 6 as shown in FIGS. 4 and 5, and the locking ring 7 is inserted into the frame from inside the bag 6. 2, the bottom part 8 of the bag body 6 is locked to the frame body 2, and the opening 3 is sealed by the bottom part 8.

The outer container 13 is a normal rectangular corrugated paper container, and the side body 9 can store the inner container 1 in parallel, and the inner flap 10, 10 connected to the upper opening has a half-moon shape on the front edge. The sixth notch portions 17 are formed to face each other.
As shown in the figure, the flange of the frame body 2 of the inner container 1 and the bag body 6
The inner container 1 is locked by being inserted into the gap between the inner container 1 and the bottom surface 8 of the inner container 1.

On the other hand, the outer flap 11.11 connected to the upper opening of the outer container 13 locks and stores the frame 2 of the inner container 1 with the inner flap 10.10, as shown in FIGS. 1 and 6. When the outer flap 11.11 is sealed, the frame body 2 and the lid body 5 are made to face each other so as to butt at the center of the upper opening, and when the outer flap 11.11 is sealed, A break line 12.12 is made along the shape of the lid body 5,
When sealing, it was attached at a position facing the inner flap 10.10.

Therefore, when the inner container 1 is attached to the outer container 13 and sealed as shown in FIGS. 7 and 8, the frame 2 of the inner container 1 is locked by the inner flap 10.10 of the outer container 13. By bonding the inner and outer flaps 10.10, 11, 11 together, the inner and outer flaps 10.10, 11, 11 are integrated, and the flange portion of the frame body 2 is clamped and securely fixed to the outer container 8.

When storing items such as liquids, the outer container 13 with the inner container 1 attached thereto is tipped over as shown in FIG. After filling with liquid or the like, the opening of the bag body 6 is heat welded, the heat welded part is folded into the square bottom, and the flap 18 is sealed to complete the packaging.

When taking out the stored article, as shown in FIG.
The bottom part 8 of the bag body 6 whose two parts are removed to expose the lid body 5 of the inner container 1 and whose opening 3 is sealed by removing the lid body 5
The stored article is taken out by cutting it out, and then the lid body 5 is attached to reseal it.

In this manner, when opening and closing the lid 5 to take out stored items, the frame 2 is securely fixed to the outer container 13, so opening and closing the lid 5 is easy.

Moreover, when the stored articles are taken out, the amount of contents filled in the bag body 6 decreases, but the frame body 2 has inner and outer flaps 10 and 1.
0, 11, and 11, even if the amount of stored articles decreases, the frame body 2 does not descend and there is no problem in taking out the stored articles.

In the above embodiment, the bag body 6 of the inner container 1 is a bag-shaped body folded in two, but the present invention can also be applied to a bag-shaped body in which the bottom surface 8 of the bag body 6 is formed into a square bottom in advance. Although this does not impede the purpose, it can be manufactured at a low cost by using two bag-like bodies as in the previous embodiment.

Furthermore, when assembling the inner container 1, an example is shown in which the bottom part 8 of the bag body 6 is attached to the frame body 2 using the locking ring 7, but only the frame body 2 that has been closed in advance has the flange part of the frame body 2 inside. After mounting so as to be sandwiched between the inner flap 10.10 and the outer flap 11.11, the opposite opening 19 of the outer container 13 is opened.
Then, the bottom surface 8 of the bag 6 is brought into contact with the lower peripheral edge 3d of the frame 2, and then the locking ring 7 is fitted onto the outer periphery 3b of the peripheral edge and is locked at the stepped portion 4, thereby attaching the bag to the frame 2. A body 6 may also be attached.

As is clear from the above description, the present invention can be disassembled into the lid 5, frame 2, locking ring 7, bag 6, and outer container 13 for storage and transportation before use. In addition, during assembly, the inner container 1 is assembled by attaching the bag body 6 to the frame body 2 by fitting the locking ring 7, and the inner container 1 is assembled with the bag body bottom part 8 of the frame body 2. The inner container 1 can be attached by simply inserting the inner flap 10.10 of the outer container 13 into the gap, and both flaps 10, 10.1
The frame body 2 can be reliably fixed and the inner container 1 can be housed by simply pasting the frames 1 and 11 together.

Furthermore, when in use, the frame 2 of the inner container 1 is locked by the inner flap 10.10 of the outer container 13, and is covered and clamped and fixed by the outer flap 11.11. Even when the frame 2 of 1 is subjected to vibrations or shocks when storing and transporting articles, it does not move on its own and therefore repeatedly bends around the joint between the frame 2 and the bag 6, causing the pins to break. There is no risk of holes forming, and the outer surface of the outer container 13 is flat after the articles are stored, so it is easy to stack them and transport or store them, and also to take out the stored articles. Outer flaps 1.11
The lid 5 can be opened and closed by simply cutting out the break line 12 made on the frame 2, and the lid 5 can be opened and closed because the frame 2 is securely fixed to the inner and outer flaps 10°, 10, 11, and 11. It is very easy to take out the stored articles, and even if the contents are reduced, the frame body 2 does not descend, so that it is easy to take out the articles and there is an effect of providing a composite packaging container with a simple structure.
