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.

Traditionally, composite packaging containers have an outer container made of paperboard with a synthetic resin film bag inside to store liquids, etc.
A bag provided with a spout is used.

In this type of product, as shown in Figure 7, including the pouring field C attached to the upper part of the synthetic resin film bag body a,
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 is repeatedly folded around spout C, causing fatigue and damage to the outside. There were drawbacks such as pinholes caused by friction with the container and leakage.

Furthermore, when taking out the spout C from the outer container, if the bag body a is not sufficiently filled with liquid, etc., the position of the spout C will move and the position of the spout C will move to take out the spout C. This necessitated troublesome work such as having to search for the item while taking it out.

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 can also be used as a daily container because it is easy to take out stored items and the lid can be reclosed after opening. A frame body 2 having an opening 3 with a peripheral edge 4 protruding downward; a lid body 5 that removably fits into and closes the opening 3; and a bottom surface portion 7 around the entire lower edge of the inner peripheral edge 4 of the frame body 2. an inner container 1 consisting of a synthetic resin film bag body 6 which is welded and whose lower part is open; a side body 9 in which the bag body 6 is placed; and the frame body 2 connected to the upper opening of the side body 9; A pair of opposing inner flaps 10.10 are inserted into the gap with the bag bottom part 7 to lock the frame 2, and the frame 2 in a closed state is locked to the inner flaps 10.10. A pair of opposing outer flaps 11.11 covering the outer flaps 11.11 and a pair of outer flaps 11.11 that follow the shape of the lid 5 to correspond to the position of the lid 5 when the outer flaps 11.11 are sealed. Break line 1 formed in
2.12, an outer paperboard container 8 comprising an inner flap 10.10 and an outer flap 11.1;
It is characterized in that it is attached at a position facing inward from 1.

The present invention will be explained in more detail with reference to FIGS. 1 to 6, which show an example of implementation of the present invention.

As shown in the first figure, it is composed of an inner container 1 and an outer container 8.

As shown in FIGS. 1 and 4, the inner container 1 has an inner peripheral edge 4 of an opening 3 formed in a ring-shaped frame 2 projecting downward, and a synthetic resin film bag 6 is provided around the entire inner peripheral edge 4. It is formed by welding the bottom part 7 of the.

The bag 6 is a bag-like body folded in two, and the width of the bottom edge 13 is larger than the diameter of the frame 2, and the side circumferential surface including the bottom edge 13 is aligned with the inner circumferential surface of the bag Fold along the side edge 1
A bottom part 7 which can be flattened and expanded by welding integrally with 4 is formed.

The upper edge of the inner circumferential edge 4 of the frame body 2 is formed to descend by the thickness of the side circumferential surface of the lid body 5, so that when the lid body 5 is attached, the surface of the lid body 5 is
I tried to make it less prominent.

A concentric solid bead 15 is formed on the lid 5 to prevent the lid 5 from being bent and difficult to attach when the lid 5 is made of a thin soft synthetic resin.

The outer container 8 is a normal rectangular parallelepiped-shaped corrugated paper container with a side body 9.
The inner container 1 can be stored in parallel, and the inner flaps 10.10 connected to the upper opening have half-moon-shaped notches 16 formed at the front edges thereof and face each other. 2, the inner container 1 is locked by being inserted into the gap between the frame 2 of the inner container 1 and the bottom surface of the bag 6.

On the other hand, the outer flap 1 is connected to the upper opening of the outer container 8.
1.11 is such that when the inner flap 10.10 locks the frame 2 of the inner container 1 and stores it, the inner flap 10.10 abuts against each other at the center of the upper opening so that the frame 2 and the lid 5 can be covered. When the outer flap 11.11 is further sealed,
A break line 12.12 is made along the shape of the lid 5 below the outer flap 11.11, and is attached at a position facing the inner flap 10.10 when sealing.

Therefore, when the inner container 1 is attached to the outer container 8 and sealed as shown in FIGS. 3 and 4, the frame 2 of the inner container 1 is locked by the inner flaps 10 and 10 of the outer container 8. By pasting 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 8 with the inner container 1 attached thereto is tipped over as shown in FIG. After filling with liquid etc., the opening of the bag body 6 is heated and welded,
Fold the heated welded part into the corner bottom and create the lower flap 17.
Seal and complete the packaging.

When taking out the stored article, as shown in FIG. is removed and the bottom part 7 of the bag body 6 sealing the opening 3 is cut out to take out the stored article, and then the lid body 5 is attached to reseal it.

In this way, when opening and closing the lid 5 to take out stored items, the frame 2 is securely fixed to the outer container 8, so opening and closing the lid 5 is easy.

Moreover, when the stored articles are taken out, the content filled in the bag body 6 decreases, but the frame body 2 has inner and outer flaps 10, 10
, 11.11, 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-like body folded in two, but the present invention can also be achieved by using a bag-like body in which the bottom surface 7 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 a bifold bag-like body as in the above embodiment.

As is clear from the above description, when the present invention is used, the frame 2 of the inner container 1 is connected to the inner flaps 10 and 10 of the outer container 8.
Since the outer flaps 11 and 11 cover and clamp and fix the inner container 1, it can move independently even if the frame 2 of the inner container 1 is subjected to vibrations or shocks when storing and transporting items. Therefore, there is no risk of pinholes occurring due to repeated bending around the joint between the frame body 2 and the bag body 6, and the external surface of the outer container 8 is flat after the goods have been stored. Therefore, it is easy to stack them for transport or storage, and to take out the stored items, the lid 5 can be opened and closed by simply cutting out the break line 12 made on the outer flap 11, 11 of the outer container 8. Since the frame 2 is securely fixed to the inner and outer flaps 10, 10, 11, 11, opening and closing of the lid 5 is extremely easy. 2 does not descend, making it easy to take out articles and providing a composite packaging container with a simple structure.
