Solution

A multi-tiered paper container having a pair of front and rear side plates 2 and 3 and a pair of left and right side plates 4 and 5 around a square bottom plate 1 and a lid are combined to form a prefabricated paper heavy box made of each paper. The outer walls 21, 31, the upper edge overlapping portions 22, 32, the receiving portions 23, 33, the inner walls 24, 344, and the bottom plate overlapping portions 25, 35, in which the front and rear side plates 2 and 3 of the container are connected in order from the bottom plate 1 in the outward direction, respectively. The upper edge overlapping portions 22 and 32 are attached to the outer walls 21 and 31, and the bottom plate overlapping portions 25 and 35 are attached to the bottom plate 1, while the left and right side plates 4 and 5 in each paper container A are attached to the bottom plates, respectively. It is composed of outer walls 41, 5, inner walls 42, 52, and bottom plate overlapping portions 43, 53, which are connected in order from 1 to the outside, and when assembling each paper container, the front, rear, left, and right side plates 2, 3, 4, and 5 are bottom plates. By standing in a tapered shape with the flat opening side wider than the 1 side, the front and rear edges of the bottom plate 1 of the upper paper container are placed on the receiving portions 23, 33 of the front and rear side plates 2 and 3 of the lower paper container. It was decided to store the resin partition tray in the paper container.

In order to reduce the number of component parts of the heavy box body, facilitate manufacturing and assembly, and reduce manufacturing costs, the colors of the surface of the bottom plate and the inner wall of the rising wall are matched to similar colors, and a film is attached to decorate and decorate. Be hygienic and omit the insoles. The rectangular side wall is folded with a V-shaped lateral groove, the bent groove and the bottom plate fitting groove are cut, and the joint is cut to form, and the bent groove is cut into the rectangular rising wall to cut the joint. And form. While fitting the bottom plate into the fitting groove of the outer wall, bend and erect the side wall on the peripheral edge of the bottom plate, glue the joints to assemble the heavy box outer frame, and bond and fix the similarly assembled rising wall to the inside to fix the heavy box body. It has been completed (see Patent Document 3).

The conventional prefabricated paper container has a simple box shape (rectangular bottom part and each side part of the bottom part) with the upper surface open due to the restriction that each part of one sheetboard is bent and formed. Most of them have a shape consisting of four side parts), and many of them have difficulty in appearance and functionality as a lunch box. For this reason, in order to improve the appearance of the lunch box and the functionality of the lunch box, various measures have been taken for the paper container used for the lunch box. It has been proposed that each side surface portion of the paper container is inclined outward so that the opening portion of the paper container is formed wider than the bottom surface portion (see Patent Document 4).

Since the resin tray can be supported at a high position inside the paper container (lunch box is raised and bottomed), it is also possible to make the amount of food contained in it look more luxurious than it actually is. It makes it possible to make the lunch box look bigger and make the amount of food in it look more luxurious than it really is. In addition, an inner wall is formed inside the side surface at a portion folded downward from the upper edge of the side surface of the paper container so that the edge of the resin tray can be hung on the step provided on the inner wall. Has also been proposed (see Patent Document 5).

However, since the bottom surface of the paper container is directly installed on the mounting surface, there is a drawback that it is difficult to put a finger under the bottom surface and it is difficult to carry. In order to make the paper container easy to carry, it is possible to devise measures such as providing a handle and a finger hook hole on the side surface of the paper container, but the appearance of the paper container will be worse and the strength of the side surface will be deteriorated. It is difficult to provide a handle or a finger hook hole with a single sheet of paper while maintaining the above. In addition, since the front surface of the bottom surface of the paper container is in contact with the mounting surface, there is a drawback that the bottom surface of the paper container gets wet when juice or the like spills on the mounting surface. .. The paper container could be soaked and torn if it got wet. A notch is provided in the bottom surface of the paper container, the tip of the portion folded inward and downward from the upper edge of the side surface of the paper container is projected downward from the notch, and the protruding portion is formed in the paper container. A material that can be used as a leg has also been proposed (see Patent Document 6).

In view of such a situation, it is possible to prevent the bottom surface of the paper container from getting wet even if soup or the like spills on the mounting surface of the lunch box. Further, since the bottom surface of the paper container can be floated above the mounting surface, there is an advantage that it is easy to put a finger under the lunch box and the lunch box is easy to carry. Since the paper container must have a notch in the bottom surface, it is difficult to maintain the strength of the bottom surface. In addition, because the notch is provided on the bottom surface, the leg can be formed only locally, and the leg can be formed only with the thickness of one sheet of paperboard. It is also difficult to increase one's own strength. There is also the drawback that the legs spoil the appearance of the paper container. Even if a paper container is used for a lunch box for packing a relatively high-class lunch box, a high-class feeling is required. A paper heavy box has not been proposed that solves these problems, is easy to assemble, does not use adhesives, and the like.
