Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a food packaging method.

(Prior Art) Conventionally, a food packaging container is made by integrally molding a container body with a plurality of recesses and a lid connected through a bendable bending part from a thin synthetic resin plate. is known as Utility Model Application Publication No. 167710/1983. In addition, the front and back sides of the package are formed on the heat-sealable original fabric on the first production line, and then the package is cut into block units without being made into a container shape, which is then center-folded on another line. Primary sealing, filling, sealing, and finally punching are performed, and a molded part consisting of projections or notches for transport positioning is formed near the periphery of the unit block, and transport from the first line to the second line is carried out through this. Such a device is disclosed in Japanese Patent Application Laid-Open No. 60-204427.

(Problems to be Solved by the Invention) According to the food packaging container of Utility Model Application Publication No. 60-16771 as described above, the container body and the lid portion are connected at the bent portion, so that It is not possible to take out the contents.

Then, it is taken out using an auxiliary object such as a skewer.

In addition, since there is no stationary part, it cannot be left in a packaged state.

Therefore, there is no display effect in stores, and extra materials such as skewers are required. Furthermore, JP-A-1986-
Similarly, in the case of the product disclosed in Publication No. 204427, the moldings on the front and back sides are not easy to open, so the contents cannot be taken out in a peach-shaped manner, and since no hook is formed, it cannot be left in a packaged state.

(Means for Solving the Problems) Therefore, the technical problem of the present invention is to provide a food packaging container that allows the contents to be eaten without the need for auxiliary tools and that has a great display effect. The technical means of the present invention to solve this technical problem is as follows.

In other words, a left body and a right body, which are two three-dimensional molded parts, are placed horizontally on the left and right with the hakama section in between, and then integrated by vacuum or pressure forming using a mold from a plastic sheet. After forming, the outer shape is punched out from the sheet, and the center of the hook part is cut to separate the left body with the hook and the right body with the hook, and then these separated parts are assembled into a three-dimensional shape to form the outer circumference of the main body. The product is made into a sheet that can be opened easily, and then the contents are filled from the bottom part of the three-dimensional molded product, and after the bottom part of the three-dimensional molded product is hermetically sealed, it can be left in place.

(Effect of the invention) According to this technical means, the molding method is to simultaneously mold the left body and the right body into a two-part shape, so the molding is easy, and the assembly is easy. It is easy to fill the contents afterward, and since it can be opened in a peach-like shape, the contents can be eaten hygienically without the need for any other auxiliary tools. Since it is molded, it can be left stationary and the display effect at stores can be enhanced. In addition, the left and right three-dimensional molded parts can be separated without damaging or deforming them using the hook part, and the contents can be easily filled using the hook part with a large opening to ensure that the sealing surface does not shift. It has the characteristic of being sealed. Furthermore, since the right body with a hook and the left body with a hook are integrally molded and then cut from the center, it is possible to seal them without shrinkage of the sheet molded product or slight errors in the mold, unlike those that are molded separately and sealed together. The sealing can be completely ensured because the sealing surface will not shift due to mismatching of the cut surfaces.

(Example) Figures 1, 2, and 3 show a food packaging container molded by the method of the present invention, in which Figure 1 is a front view, Figure 2 is a side view with an excess hakama portion, and Figure 3 is a side view with an excess hook part. The figure is a bottom view showing a partially cut away lid.

The food packaging container as described above is formed of a left main body 1 and a right main body 2, which are formed by dividing a three-dimensional molded product into left and right halves, and are sealed along the outer periphery so that they can be opened easily. 1 is the hook part of the three-dimensional molded product, and there is a hanger hole 4 in the upper part.

5 and 5 are arrows indicating the opening direction, and when the package is opened from this opening, the contents a can be eaten by holding the packaging materials of the left and right bodies 1 and 2, which are opened in the shape of a peach as shown in Fig. 4. This is possible.

In this case, it is better that the seal on the hook portion 3 is not easy to open. In this way, the hinge part 3 acts like a hinge, allowing the package to be opened in a peach-like pattern.

The food packaging container described above can be hung on a hanger or placed on the floor, and the opened contents are three-dimensional, and can be easily made three-dimensional by filling with viscous food.

In addition, three-dimensional molded products have a large display effect at stores because of the bulges of animals printed on the surface.

In order to mold the above-mentioned object, as shown in Fig. 5, the left main body 1 and the right main body 2 are arranged horizontally on the left and right with the hook part 3 in between, and then the left main body 1 and the right main body 2 are arranged horizontally on the left and right with the hook part 3 in between. Vacuum or pressure forming is performed using a mold.

Next, the outline is punched out from the sheet.

6 in FIG. 5 indicates the punching line.

Next, cut with a hot wire from the cut line 7 of the hook part 3.

The left main body 1 and the right main body 2 are separated by cutting as described above.

Next, these separated bodies are assembled into a three-dimensional shape, and the outer peripheries 1a and 2a of the bodies are sealed for easy opening.

Next, the extra hook part 6 is cut off from the line A in FIG. 2 so that the hook section 6 can be sealed tightly and left in place.

Next, the contents are filled from the top part 3, and the bottom part of the three-dimensional molded product is hermetically sealed with, for example, an elliptical lid 8 as shown in FIG.

By the above-described molding method, three-dimensional molded products as shown in FIGS. 1, 2, and 3 can be produced.

According to such a molding method, that is, a packaging method, as in the present invention, the product is molded in two parts on the left and right, so molding is easy and assembly is easy.

Note that solid foods can also be packaged after the packaging according to the shape of the molded product.
