Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention incorporates into a drum can a flexible inner container which is mounted inside a drum can and stores various liquids and powders therein to store and transport them. For loading the inner container into the drum for
It relates to an interior container used for this.

[0002]

2. Description of the Related Art Conventionally, drums have been widely used as containers for storing and transporting fluid materials such as various liquids and powders.

Although the used drum cans can be recycled for reuse by washing, the present situation is waiting for the proposal of means for effectively utilizing the used drum cans.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to allow an inner container to be easily loaded into the inside of a drum can having a small diameter plug portion, without cleaning the used drum can internally. An object of the present invention is to provide an inner container loading method that can be reused for storage and transportation of a fluid material similar to a new product, and can effectively use a drum, and an inner container used for this method.

[0005]

In order to solve the above problems, the invention of a method is to provide an inner container made of a flexible material at the upper end of the container body to be housed inside the drum can, and to a top plate of the drum can. The inner body of the inner container is folded into a rod shape so that the mouth is at the upper end, and the rod-shaped container body is inserted from the mouth portion of the drum can to the inside of the drum can. The container body is inserted into the container, the air is injected into the container body from the mouth located at the mouth plug portion, and the container body is expanded inside the drum can.

Further, the invention of the inner container is such that the container body made of a flexible material such as polyethylene can be housed inside the drum can by closing the upper and lower ends of the cylindrical body with the upper wall and the lower wall. And a mouth portion corresponding to the mouth plug portion of the drum can is projectingly provided on the upper surface of the upper wall.

The folding of the inner container is performed by flattening the tubular body so that the upper wall and the lower wall are vertically arranged, and rolling the inner body inward from the end portions of the upper wall and the lower wall. It is performed by forming the mouth part of the upper wall as the top part and winding it from both ends to the center and stopping the two round bar-shaped bodies with adhesive tape such as paper to form a bar-shaped body that can pass through the mouth part of the drum can. .

The rod-shaped body is inserted by inserting it into the drum can from the spout, and for example, by folding the spout outward along the spout, the rod-shaped body is mounted by pressurizing air from the spout in this state. Complete the interior by inflating the tubular body.

At this time, the adhesive tape is broken to allow the cylindrical body to swell.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the inner container 1 used in the loading method of the present invention is made of a material having flexibility, airtightness and water-blocking property, such as polyethylene, and the upper and lower ends of the tubular body 2 are raised. A container body 5 is formed by closing the wall 3 and the lower wall 4, and the container body 5 is sized so as to fit inside the drum can 6 shown in FIG. A cylindrical mouth portion 8 corresponding to 7 is provided in a protruding shape.

To mount the inner container 1 inside the drum can 6, as shown in FIG. 1, with the container body 5 held in a container shape, as shown in FIG. The upper wall 3
And the lower wall 4 are vertically overlapped with each other so as to be overlapped with each other to flatten the container body 5, and the flat container body 5 is wound inward from the end portions of the upper wall 3 and the lower wall 4 so that the container body 5 becomes The mouth of the wall becomes the top and is rolled from both ends to the center to form two round bar-shaped bodies, which are fastened with an adhesive tape 9 such as paper, and the container body 5 is placed in the plug portion 7 of the drum can 6. Is formed into a rod-shaped body B that can pass through.

In order to mount the above-described inner container 5 formed in the rod-shaped body B inside the drum can 6, as shown in FIG. From the mouth 8 into the interior of the drum 6 as shown in FIG. 6 with the mouth 8 folded back to the mouth plug 7 or attached. When air is pressed into the inside of the container 5, the container body 5 to which the internal pressure is applied tends to swell, and the adhesive tape 9 is broken or peeled, so that the container body 5 in the folded state swells in the drum can 6,
As shown in FIG. 7, the tubular body 2, the upper wall 3 and the lower wall 4 are mounted along the inner peripheral surface of the drum can 6 to complete the interior.

As described above, if the fluid material such as various liquids or powders is filled from the mouth portion 8 into the drum can 6 having the inner container 1 incorporated therein, the drum can 6 having the shape-retaining property is filled with it. The held material does not come into contact with the inner surface of the drum 6 in the inner container 1, so that the filled material can be stored and transported without any trouble.

As described above, if the inner container 1 is housed in the unwashed drum can 6, the drum can 6 can be used as a new one. For example, the used drum can 6 is housed in the inner container 1 in the event of a disaster. Filling up with drinking water can help in an emergency.

After using materials such as various liquids and powders filled in the inner container 1, the inner container 1 is pulled out from the inside of the drum can 6 at the mouth plug portion 7, and then a new interior If the container 1 is placed in the drum can 6 in the same manner as described above, the drum can 6 can be repeatedly used.

[0017]

As described above, according to the present invention, a container body made of a flexible material is folded into a rod shape so that the mouth portion is located at the upper end, and the rod-shaped container body is inserted from the plug portion of the drum can to the drum can. It was inserted inside, and air was injected into the inside of the container body from the mouth located at the mouth part, so that the container body was expanded inside the drum can, so the top plate had a small diameter mouth part. An inner container of a size that fits inside the drum can can be attached to the inside of the provided drum can, and even an unwashed drum can be used as a new product. However, if the inner container is filled with drinking water and transported, it will be useful in an emergency and the surplus drum can can be effectively used.

Further, since the container body made of a flexible material is formed in a size that can be accommodated inside the drum can, and the mouth portion corresponding to the mouth portion of the drum can is projectingly provided on the upper surface of the upper wall. The inner container can be manufactured at low cost, and the inner container can be disposable.
