Description

[Detailed Description of the Invention] The present invention relates to a versatile container for packaging solid substances such as liquids or powders.

More specifically, the present invention relates to a packaging container which is a composite sealed container composed of an inner container body having a resealable lid for taking out stored articles and an outer container for protecting the inner container body.

Conventionally, a bag made of synthetic resin film containing a liquid is housed in an outer container made of paperboard, and a spout is provided in the bag.

In this type of bag, creases inevitably occur in the upper part of the inner synthetic resin film bag, and as the stored liquid moves due to vibrations and shocks during transfer, the corners of the creases There were drawbacks such as pinholes and leakage caused by repeated bending fatigue and friction with the H-rule container.

Furthermore, since the spout is small, it is unsuitable for storing and dispensing solid materials such as highly viscous liquids or powdered products.

For this reason, metal containers (gallon cans, bale cans, etc.) and thick-walled containers made of hard synthetic resin have traditionally been used for these types of items, but these are usually treated as disposable containers and are uneconomical. Moreover, the weight and space of the container itself are large, making it inconvenient to transport.

The present invention overcomes the drawbacks of the conventional methods and has a simple structure and is lightweight, and can be easily folded and transported when not in use, and is easy to assemble, especially for storing solid materials such as highly viscous liquids or powder products. To provide a versatile packaging container that can be resealed and easily taken out, a side body 3 having both sides thereof,
An outer container comprising cover plates 8 and 9 for sealing the opening and made of paperboard; a frame 4 having a shape matching the cross-sectional shape of the inner surface of the side body 3; and an opening provided in the frame 4. 5 is provided with a lid 6 that can be attached freely, and the synthetic resin film bag 7 has an opening 12 and a sealed bottom 13 on the other side, and the sealed bottom 13 is formed on a flat surface 14. The inner container body 2 is fixed to the entire inner surface of the frame body 4 and the opening 5 of the frame body 4 is sealed.
The bag body 7 is housed and packaged by fitting the frame body 4 into the inner surface of the side body 3.

The present invention will be further explained with reference to the drawings showing an example of implementation of the present invention.

The outer container 1 is made of corrugated paperboard, and has a rectangular prism-shaped side body 3 and cover plates 8 and 9 connected to the edges of the opening on both sides of the side body 3.
It has upper and lower flaps.

This cover plate 8.9 may be separate from the side shell 3.

The inner container body 2 consists of a frame body 4, a lid body 6, and a bag body 7.

The frame 4 is made of hard synthetic resin, has a shape that matches the cross-sectional shape of the inner surface of the side body 3 of the outer container 1, and has a ridge 10 on its periphery.

The bag body 7 is formed from a synthetic resin film and has an opening 12 on one side and a sealed bottom 13 heat-welded on the other side.

Then, the sealed bottom 13 was folded into a square bottom to form a flat surface 14, which was heat-sealed or hot-melt bonded along the entire inner surface of the frame 4 to seal the opening 5 of the frame 4.

In order to form the sealed bottom 13 into a flat surface in this way, the sealed bottom 13 is formed in advance without folding as shown in the figure.
3 may be formed to be a flat surface 14.

Therefore, the bag 7 fixed to the frame 4 has an opening 12 at the opposite end of the frame 4.

The lid body 6 is made of hard synthetic resin and is independent at an appropriate length so that it can be freely engaged with and detached from the inner edge of the opening 5 of the frame body 4 so as to close the opening 5 of the frame body 4 as shown in the third figure. The projecting piece 11 has a ring shape, and is thereby inserted into the opening 5 of the frame body 4 which is sealed by the bag body 7.

Reference numeral 15 indicates a knob provided at a corner of the lid 6.

When storing articles, the upper flap 8 of the outer container 1 is sealed as shown in FIG. When the inner container body 2 is inserted into the outer container 1 from the opening on the 9 side with the frame body 4 closed with the lid body 6 facing downward, the bag body 7 of the inner container body 2 has a frame body 4 that is similar to the 91-4 container 1. The bag body 7 is inserted while being guided along the inner surface of the side shell 3, and the bag body 7 is inserted along the inner surface of the side shell 3.

Next, in this state, the opening 1 of the bag body 7 of the inner container body 2
2, a solid substance such as a liquid or a powder product is filled and stored in the inner container body 2, and then the opening 12 of the bag body 7 is evacuated and sealed by heat welding.

At this time, the opening 5 of the frame located below inside the outer container 1 is
Since the bag body 7 is sealed with a flat surface 14 formed by folding the sealed bottom part 13 into a square bottom, the liquid to be filled or a solid substance such as a powder product will leak from the gap between the lid body 6 and the opening 5 of the frame body. There's nothing to do.

Thereafter, the welded and sealed portion of the bag body 7 of the inner container body 2 is folded into the square bottom and inserted into the side body 3, and the lower flap 9 of the outer container 1 is sealed to complete the packaging.

In this packaging completion state, the frame body 4, lid body 6, and bag body 7 that constitute the inner container body 2 housed in the R9 rule container 1 are stored in close contact with the inner surface of the evening bag+J container 1. Since the bag body 7 is not wrinkled, there is no risk of pinholes being generated even if vibrations or shocks are applied during transportation.

When taking out stored items, the upper flap 8 of the container 1 is opened, the lid 6 is detached from the frame 4 of the inner container body 2, and the lid is attached to the opening 5 of the frame, as shown in FIG. By cutting a portion of the bag 7 along the inner edge of the opening 5, the stored articles can be easily taken out, and by attaching the lid 6 to the opening 5 of the frame 3, they can be resealed and stored.

Thus, according to the present invention, the flat surface 14 formed on the sealed bottom 13 of the synthetic resin film bag body 7 is formed on the entire inner surface of the frame body 4 whose shape matches the cross-sectional shape of the inner surface of the side body 3 of the container 1. Now that the inner container body 2 with the opening 12 at the opposite end of the bottom 13 was formed, one cover plate 8 of the 29-rule container 1 was sealed, it was turned upside down, and the other cover plate 9 was sealed. When inserting the inner container body 2 from the opening with the frame 4 facing downward, the frame 4 enters along the inner surface of the side shell 3, and the bag body 7 can be reliably attached along the inner surface of the side shell 3. .

In addition, in such an attached state, the flat surface 1 of the bag body 7
4 is fixed so as to seal the opening 5 provided in the frame body 4, so that liquids or solids such as powder products can be stored extremely easily without leaking from the opening 12 of the bag body. The bag body 7 can be sealed simply by heat welding, making packaging simple, and the frame body 4 and the bag body 7 can be brought into close contact with the inner surface of the T-r-4 container 1 after the article is stored. Since the bag body 7 is integrated with the container 1, there is no wrinkles in the bag body 7, and there is no risk of leakage of stored articles caused by pinholes caused by vibrations or shocks during transportation.

In addition, since the lid 6 is detachably provided on the frame 4, it can be resealed, and since the frame 4 is fitted in accordance with the shape of the inner surface of the side body 3 of the outer container 1, the lid 6 can be re-sealed. Even when opening the lid,
Since the frame body 4 is fixed to the inner surface of the outer container 1, the lid body 6 can be easily opened and closed.

Further, the container 1 is made of paperboard, the bag body 7 forming the inner container body 2 is made of synthetic resin film, and the frame body 4 and lid body 6 are made of paperboard.
Since the container can be made of hard resin, the container itself can be made lightweight as a whole, and when not in use, the container can be
Both of the inner container body 2 can be folded compactly and stored, and can be easily transported.
