Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a sealed container, and more specifically, to a composite sealed container that can separately accommodate a plurality of types of foods.

[Prior art] Conventionally, multiple types of foods, such as snacks and instant foods, are placed in separate containers to prevent their quality and flavor from being impaired, and these multiple types of foods are eaten individually or mixed together. There are some foods that are eaten immediately after mixing, or after a secondary treatment such as adding boiling water. In these cases, a first container containing food and a second container containing a different food (mainly spices) are provided separately from the first container, or one container is separated by a partition plate. It is stored separately in each divided part. For example, as shown in Japanese Utility Model Application Publication No. 55-170243, a container has been proposed which consists of a combination of a top provided with a tear zipper on the outer peripheral surface of the body and a tray that can be fitted into the top of the top.

[Problems to be solved by the invention] In addition to the drawbacks of the conventional example described above, in which the container A and the upper tray B are doubled, the weight of the container itself becomes large, there is also a large amount of wasted material, and the cost is high.
There is a serious drawback in that moisture enters into the zipper A from the tear zipper 2, causing the contents to absorb moisture and mold to grow.

[Means for Solving the Problems] This invention aims to eliminate the above-mentioned drawbacks, and its features include a main body of the container made of polycoated paper having an opening; A first bottom plate that closes the opening of the container, and a second bottom plate attached to the top of a pair of perforations formed in the paper sheet excluding the polycoated surface of the polycoated paper in the main body of the container. This can be achieved by connecting them so that they can be separated by the cut.

[Example] Hereinafter, an example of this invention shown in the drawings will be described in detail.

The sealed container of this invention is shown in Figure 1 a, b and Figure 2.
As shown in Figures a and b, before pasting or coating one side of a sheet of paper with a synthetic resin thin film, a container component 1 cut from paper into a rectangular or fan shape is preliminarily cut at a certain interval in the width direction of the component. After opening the paper sheet 1b and forming perforation-like cuts 2a and 2b and V-shaped cuts 3a and 3b at the cut locations on one side edge of the component, the paper is coated with a polycoated surface 1a. is formed, and the component member 1 is curled into a cylindrical or cone shape with the surface to which the synthetic resin thin film is attached (polycoated surface 1a) inside, and both ends in the curl direction are polymerized to a certain dimension, and this polymerized portion is heated and pressurized. By doing this, the resin is melted and bonded using a glue to form the main body portion 4 of the container.

In the case of the cylindrical container main body shown in FIGS. 1a and 1b, processed paper having the same structure as the constituent members of the main body is used, and a plate having an outer diameter approximately equal to the inner diameter of the main body is used. The shaped bottom plate 5 is bonded to the opening 6 of the container main body 4 by heating and pressing.

After filling the contents into the cylindrical and cone-shaped container main body 4 shown in FIGS. 1a and 2a from the opening 7 side up to the vicinity of the cut 2a in this way,
As shown in FIG. 1b, FIG. 2b, and FIG.
b to form a first sealed container 9.

Next, the contents are put into the upper part of this bottom plate 10 from the opening 7 side up to the vicinity of the opening, and the lid plate 8 or 11 having the same structure as described above is attached by the same means as described above. A second sealed container 13 is formed. In addition, as shown in Fig. 1a and b, the structure similar to that of the connected body of two sealed containers is shown in Fig. 1b and 2.
As shown in Figure b, a multi-connected body of three or more sealed containers may be formed. Further, the shape of the container may be a cylinder, a cone, a rectangular cylinder, an elliptical cylinder, or the like.

The sealed container of this invention has the above-described structure, and in order to take out the contents from inside the container, the lid plate 11 must be removed from the second sealed container 13 without separating the first sealed container 9. However, as shown in FIG. 4, the strip 1 between the cuts 2a and 2b
The polycoated surface 1a and the paper sheet 1b may be removed integrally using the cut in No. 4 to form a unit sealed container as shown in FIG. 5, and then the lid plate may be removed to take out the contents. Although not shown, the cover plates 8 and 11
A spout may be provided in the container and the container may be sealed with a seal.

[Effects of the invention] As described above, this invention has the structure shown in the above-mentioned embodiment, so there is only a very small portion of the container that has a double structure, so there is no wastage of material, and the container itself is Since the weight of the polycoat can be reduced, it is easy to transport and manage, and since there are no perforations in the polycoat before separation, it has the special effect of not impairing its sealing performance.

[Brief explanation of the drawing]

Claims (1)

[Scope of utility model registration request] Pairs of perforation-like cuts 2a and 2b are provided at regular intervals on the sheet of paper, and V-shaped cuts 3a and 3b are provided at the locations of these cuts, and then a thin synthetic resin film polycoat is applied to the entire surface. A container component 1 is formed from processed paper, which is then curled with the polycoated surface 1a inside, and both ends in the curl direction are polymerized to a certain dimension, and this polymerized portion is heated and pressurized, and bonded with molten resin to form a container.
