This invention meets the above requirements, is suitable for mass production of solid foods, and is suitable for automating box manufacturing, filling, and sealing.
Another object of the present invention is to provide a paper container that allows a consumer to easily open and disassemble the container to take out the contents, and which prevents unauthorized opening of the container.

The paper container of the present invention includes a lid body A having a polygonal top surface and side edges connected to each side thereof, a polygonal bottom surface having the same number of angles as the top surface, and side surfaces connected to the four opposite sides thereof. In a paper container consisting of a container body B having a container body B, a fixed side piece is connected to both sides of each of one opposing side surface part via a fold or a fixed side piece is connected to each other via another side surface part, and each of the other one opposing side surface part is Container body B in which a folded part, a fixed part, and an ear part are successively arranged through a fold on the end side of the container body B.
and the fixed side piece and the side surface part with a continuous folded part are fixed in a peelable manner, and the fixed part is folded back to one opposite side edge of the lid body A which also covers the folded folded part. The package is sealed by attaching it in a peelable manner. The sealed container can be easily peeled off due to the ears connected to the secured portion, and the container body can be dismantled.

The structure of an octagonal paper container, which is an embodiment of the present invention, will be described below with reference to the drawings.

The lid A consists of an octagonal top surface 1, side edges 2, 3, 4, 5, 6, 7, 8, 9 connected to each side of the octagonal top surface 1, and fixing pieces between the side edges. For example, every other piece is connected to both sides of the side edge. That is, on both sides of the side edges 3, 5, 7, 9, adhesive pieces 3a, 3b; 5a, 5 are coated with glue, respectively.
b,; 7a, 7b; 9a, 9b are connected.
Each joint forms a fold line.

The container body B has four sides 12' of the octagonal bottom part 10,
14', 16', 18' have side parts 12, 1, respectively.
4, 16, and 18 are connected to each other, and one opposing side surface portion 12, 16 of the connected side surface portion has fixed side pieces 11a, 13 whose outer surfaces are coated with glue and have cut guides P defined therein.
a, 15a, 17a on the side, folding pieces 11b, 1
3b, 15b, 17b are connected to the bottom side, respectively, and the side surfaces 11, 13, 15, 17 are connected to both sides, and the other opposing side surfaces 14, 18 of the connected side surfaces are sequentially folded portions 14a, 18a, Adhesive parts 14b, 18b and ears 14c, 1 coated with glue
8c is connected.

The fixed side pieces 11a, 13a, 15a, 17a
The cut guide P formed in sections is a cut generally called a half cut, and is cut from the outer surface to approximately half the thickness of the paper, and is formed so as not to reach the inner surface. Furthermore, one or more chevron-shaped cutting auxiliary guides g that may or may not cross the cutting guide P are formed above the cutting guide P portion. This is a half cut similar to the cut mentioned above.

Each joint forms a fold line. Each side part 11,
The width of the upper edge of 12, 13, 14, 15, 16, 14, 18 is the lower edge, so if the width is slightly larger than each side of the bottom part 10, the cross section will be an inverted trapezoid shape, and if it is slightly smaller, the cross section will be a trapezoidal shape. The container body can be configured in any shape.

The inner base C is octagonal and has approximately the same size as the base portion 10. In other embodiments, this inner bottom C is the bottom part 10.
Even when the folding pieces 11b are other than octagonal, the number of the folding pieces 11b naturally changes, and when they are fixed, it is effective for viewing and stably placing the contents.

In addition, when the lid A and the container body B are integrally molded from one blank sheet, one of the side edges 3, 5, 7, and 9 of the lid A is omitted as shown in FIG. Either the side surface portion 14 or 18 of the container body B may be connected to one side of the top surface portion 1 of the lid body A. In this case, the folded portions 14a, 18a, the fixed portions 14b, 18b, and the ears 14c, 18c, which are continuously provided on the side surface portions, are omitted.

For the fixing, an appropriate glue, pressure-sensitive or heat-sensitive adhesive, etc. should be used as appropriate; therefore, the term "gluing" refers to general fixing of articles, such as gluing or adhesion.

Furthermore, the blank sheet constituting the paper container of the present invention is not limited to paper; for example, processed paper laminated with a synthetic resin sheet such as aluminum foil, cellophane, or polyethylene, or other processed paper can be used.

The procedure for assembling the paper container of the present invention will be explained below.The paper container of the present invention is constructed by folding each connecting part, standing up the side parts 12 and 16 connected to the bottom part 10 as shown in FIG. 17b on the bottom part, and stand the side parts 11, 13, 15, and 17 on each side of the bottom part, and put the side part 14 on the fixed side pieces 13a and 15a, and the side part 18 on the fixed side pieces 17a and 11a, respectively. It is fixed at least at the cut guide P part, and 14
By folding a and 18a outward, the container body B
, and attach folding pieces 11b, 13b, 15 on the bottom part 10 of the assembled container body B as necessary.
b, Insert the inner sole C on top of 17b.

On the other hand, the cover A is folded at each connecting portion, and the fixing piece 3a,
3b; 5a, 5b; 7a, 7b; 9a, 9b are fixed to the side edges 2, 4; 4, 6; 6, 8; and 8, 2, respectively, to form an assembly.

When an article is stored in the container body B, the upper edge is covered with the lid A, and the fixing parts 14b and 18b of the container body B are folded and fixed to the side edges of the lid A on the folded parts 14a and 18a, the container is It will be sealed.

In addition, when the container main body B and the lid body A are integrally molded, it is sufficient to fold back and fix one of the folded parts 18a and the fixed part 18b.

It will be easily understood that the paper container of the present invention configured as described above is suitable for automating the assembly of boxes, that is, the manufacturing of boxes, the storage of articles, the covering and sealing of lids.

The sealed container has an ear part 1 as shown in FIG.
Pinch 4c and 18c and pull them to the side (Figure 3a)
The fixed parts 14b and 18b are easily peeled off from the side edge of the lid A, and when the ears are further pulled, the folded part is stretched, and the lid A is lifted accordingly. Remove (Figure 3b). After that, further pinch the ears and pull them to the side, and the side part 1
4 and 18 are fixed side pieces 13a, 15a; 17a,
It is easily peeled off from the cut guide p portion of 11a, leaving a cut p' mark (FIG. 3c). In addition, at this time, the chevron-shaped cutting auxiliary guide g formed in the upper part of the cutting guide p corrects variations in the application position of adhesive such as glue, making it extremely easy to start peeling off, and The disassembly of main body B is carried out smoothly. Note that p' is the resection mark. Next, the side part 12,
