Description

[Detailed Description of the Invention] The present invention relates to a paper container that can be used for cooking rice and boiled foods in a microwave oven.

Recently, microwave ovens have become widespread in ordinary households. Along with this, various instant foods prepared using microwave ovens have started to appear on the market. As we all know, when using a microwave oven, food must be made of metal (for example, aluminum).
You cannot cook it in a container. If you put it in a plastic container and cook it in the microwave,
The high heat generated can cause the plastic container to soften and deform, potentially causing the food inside the container to spill out. Therefore, food sealed in aluminum or plastic containers had to be transferred to another ceramic container and then heated in a microwave oven.

An object of the present invention is to provide a paper container that can be used as a packaging container, a container for cooking in a microwave oven, and as tableware.

Hereinafter, the container according to the present invention will be explained with reference to the accompanying drawings.

FIG. 1 is a plan view of a paper container according to the present invention. The container of the present invention is a blank 1 shown in FIG.
Can be assembled from scratch. A water-resistant thermoplastic film such as polyethylene is laminated on the surface of the blank 10 corresponding to the inside of the container.

FIG. 2 is a perspective view of a container 11 of the present invention assembled from a blank 10.

In the container 11 of the present invention, a tearable pull-open portion 1 is provided at the boundary between the container roof portion 5 and the container body portion 6. This pull-open part 1 has a discontinuous upper perforation line 2 cut into a horizontal T-shape.
and a discontinuous lower perforation line 3 cut into a horizontal T-shape and disposed at an arbitrary width from the upper perforation line 2. The upper perforation line can be arranged along the line of intersection 7 of the container roof 5 and the container body 6, as shown in FIG. At this time, make a shallow cut at the upper perforation line 2, and
The lower perforation line 3 can be deeply cut.
The conventional pull-open part had a key-shaped perforation line. If the container is made of paper only, peeling will not cause any problems. However, when the paper was laminated with a thermoplastic synthetic resin film, a phenomenon was observed in which only the laminated film rolled up when the package was opened. On the other hand, as in the present invention, the perforation is
When arranged in a letter-shaped manner, even if a thermoplastic synthetic resin film is laminated on one side of the paper, the laminated film will not roll up when the package is opened.

At one end of the pull-open portion 1, a peel end piece portion 4 is provided that can be picked up with fingers in order to tear off the pull-open portion.
The peel end pieces of the conventional pull-open part are disposed at the side seam parts (for example, 22 in FIGS. 1 and 2) where both left and right ends of the blank are glued. However, if a peel end piece is provided at the side seam and peeling is started from there, the side seam is an adhesive surface and the perforations have little effect, resulting in very poor peelability. Also, adding an extra tab for peeling uses more paper,
Moldability deteriorates. In the container of the present invention, such a drawback has been successfully avoided by arranging the peel end piece 4 at the corner of the container. Therefore, in the container according to the present invention, as shown in FIG. It can also be used in such a manner that the pull-opening is stopped at another corner of the side. In this way, the container roof 4 and the container body 5 remain connected by the pull-open unseparated piece 8. It is also possible to match the heights of the container roof 5 and the container body 6. Furthermore, the storage space formed by the container roof 5 can also be used to store side foods and the like.

Containers of the present invention can be manufactured using known container assembly methods and equipment. The upper end of the assembled container is folded into a gusset, and the mouth flaps 12, 12 and folded back flap 14 are formed by folding the gusset.
overlap. The overlapping flaps can be joined together with adhesive (FIG. 3).
If it is necessary to release a large amount of steam generated during cooking in a microwave oven, you can also use the clip-fastening method shown in Figures 5 to 7 instead of attaching the flap with adhesive. . In the case of clipping, when the mouth flaps of the blank 10 are folded together, the height of the fold-back flap 24 extending upward from one mouth flap is higher than the height of the fold-back flap in the case of adhesive bonding. do. Furthermore, a raised portion 26 is provided at the right end of the flap 24, projecting slightly upward (FIG. 5).
When the folding flap 24 is configured in this way,
When the folding flap 24 is folded back onto the mouth flap as shown in FIG. 6, the upper edge 25 of the flap is located lower than before. When a known clip 16 is inserted in this state, the clip clicks into place below the upper edge (FIG. 7).
To prevent the mouth flap from opening unnecessarily.

Foods can also be directly filled into the containers of the present invention. Alternatively, the food can be sealed in a separate bag, filled into a container, and then opened from the bag into the container before cooking. In this way, it is possible to cook in the microwave without using special containers such as ceramics. Also, after eating, it can be disposed of simply by incineration.

The paper container of the present invention is an economical container that can be used as packaging material, cooking utensils, and tableware, and can ultimately be disposed of very easily.
