Description

  The present invention relates to a packaging container integrally provided with a plurality of trays.

  Today, foods such as prepared dishes packed in lunch boxes are sold as frozen foods. Such frozen foods are usually frozen in a state in which cooked foods are stored in each tray of a packaging container in which a plurality of trays are connected. In addition, the tray containing the cooked food was separated from the packaging container individually at the partition part, and re-cooked after re-cooking such as heating the frozen cooked food with a microwave oven etc. A tray containing cooked food can be packed into a lunch box as it is.

  In the conventional packaging container 100, for example, four trays having the same configuration are arranged in a square shape so that the heels overlap each other, and as shown in FIG. 9 and FIG. The paddle-shaped frame body 110 that matches the shape of the box was attached by sticking it to the buttock of the entire tray.

  However, in the production of the conventional packaging container as described above, it is necessary to cut out the opening portion 111 in order to produce the rice field-shaped frame 110 in which the outer peripheral frame 112 and the partition frame 113 are integrated. In addition, the material was wasted, which was one of the causes of high costs. The reason is that the outer peripheral frame 112 has a closed shape, and therefore, a piece of paper in which the opening 111 is cut out cannot be used to create the frame 110.

  Therefore, in view of the above situation, the present inventor has developed a packaging container capable of reducing the waste of materials as much as possible and reducing the cost as a result of intensive studies.

  The packaging container according to the present invention has an opening at the top, a bottom, a wall around the periphery, and a plurality of identically configured trays having a flange projecting outward at the upper edge of the wall. The packaging container is formed by connecting the plurality of trays by sticking a frame to the entire collar portion, and the frame includes two or more outer peripheral frames and one or more partition frames. It is characterized by.

  In addition to the above configuration, the tray may have a configuration in which the outer wall surface is made of paper and the inner wall surface is a synthetic resin-coated surface.

  Furthermore, in addition to the above-described configuration, the partition frame may have a separating line.

  Furthermore, the outer peripheral frame may be configured to include two U-shaped frames.

  The packaging container according to the present invention does not have a closed shape like the outer peripheral frame in the conventional frame body, but the outer peripheral frame is formed by the frame body including two or more outer peripheral frames and one or more partition frames. Since the outer shape of the outer peripheral frame and the partition frame can be created by using the hollowed portions generated when creating the outer peripheral frame and the partition frame, there is no waste of materials and the cost can be reduced. .

  Therefore, the packaging container according to the present invention eliminates the waste of materials generated in the conventional packaging container and the high cost caused by this in the production of the frame, and there is no waste of materials in manufacturing. Since the cost can be reduced, an inexpensive packaging container can be provided.

  Hereinafter, preferred embodiments of a packaging container according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a tray according to the present embodiment, FIG. 2 is a perspective view showing a state in which a plurality of trays according to the present embodiment are arranged in parallel, and FIG. 4 is a perspective view showing a disassembled state of the frame body, FIG. 4 is a perspective view of the packaging container showing a state in which a plurality of parallel trays shown in FIG. 2 are connected by the frame body, and FIG. 5 is shown in FIG. This is a paper mold for creating a frame.

  The tray A shown in FIG. 1 is a rectangular container having an opening at the top, a bottomed wall with a wall portion around it, and an upper edge of the wall portion having flanges a1 to a4 protruding outward. The outer wall surface is made of paper, and the inner wall surface is a synthetic resin-coated surface. Four trays A are prepared, and as shown in FIG. FIG. 3 is a frame B for connecting the four trays A arranged in the shape of the above-mentioned rice field, and includes four outer peripheral frames B1 to B4 and two partition frames b1 and b2. All of them have the same L-shape and can be separated by a separation line p formed by a perforation at the center position. The tray A in this embodiment has an outer wall surface made of paper and an inner wall surface made of a synthetic resin coating surface. However, the present invention is not limited to this, and the entire tray is made of paper, or made of synthetic resin. It may be made up of.

  As shown in FIG. 4, the outer peripheral frames B1 to B4 are affixed to the ridges of the outer peripheral portion of the tray A arranged in the shape of a rice field, and the partition frames b1 and b2 are the trays A arranged in the shape of a rice field. The tray A is affixed to the part where the buttock overlaps adjacently. In addition, the length of one side of the outer peripheral frames B1 to B4 and the partition frames b1 and b2 is formed slightly longer than the length of one side of the heel portion of the tray A, and is formed on the ridge portion of the tray A arranged in a square shape. When the outer peripheral frames B1 to B4 and the partition frames b1 and b2 are arranged, the end portions of the outer peripheral frames B1 to B4 and the partition frames b1 and b2 are configured to overlap. In addition, the outer peripheral frames B1 to B4 and the partition frames b1 and b2 have a width enough to straddle the overlapping portions of the flange portions, and the flange portions of the tray A in which the partition frames b1 and b2 are arranged in a square shape. The overlapping ridges are fixed to each other by sticking to the overlapping portions, and the trays A arranged in the shape of a rice field are thereby connected to complete the packaging container 10 according to the present embodiment. The outer peripheral frames B1 to B4 have the effect of increasing the strength of the outer edge of the tray A arranged in a square shape and improving the shape retention. Moreover, the crossing part of outer peripheral frames B1-B4 in the state stuck on the tray A, the crossing part of partition frames b1, b2, and the crossing part of outer peripheral frames B1-B4 and partition frames b1, b2, respectively, Since the strength increases by overlapping, the paper material constituting the entire frame B can be thinned, leading to saving of the paper material.

  FIG. 5 shows a paper mold for creating the outer peripheral frames B1 to B4 and the partition frames b1 and b2. In this way, the L-shaped outer peripheral frames B1 to B4 and the partition frames b1 and b2 are cut adjacent to each other. As a result, paper waste can be greatly reduced as compared with conventional frame production. Therefore, significant cost reduction can be achieved in the production of the packaging container 10.

  6 is a perspective view showing an exploded state of the frame according to the present embodiment, and FIG. 7 is a view of the packaging container showing a state in which the trays in a plurality of parallel states shown in FIG. 2 are connected by the frame according to the present embodiment. It is a perspective view.

A separation line p is provided. Then, as shown in FIG. 7, two U-shaped outer peripheral frames 2B1 and 2B2 are attached to the flanges of the outer peripheral portion of the tray A arranged in a U-shape as in the first embodiment. The packaging container 20 is completed by affixing the partition frame 2b to the overlapping part of the flanges in the tray A arranged in a letter shape. The outer peripheral frames 2B1 and 2B2 have an effect of increasing the strength of the outer edge portion of the tray A arranged in a square shape and improving the shape retention. Further, since the strength of the intersecting portions of the outer peripheral frames 2B1 and 2B2 and the intersecting portions of the outer peripheral frames 2B1 and 2B2 and the partition frame 2b is increased by overlapping each other, the paper material constituting the entire frame 2B can be thinned. , Leading to savings on paper materials.
