Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a foldable paper carton in which a plurality of closely spaced storage compartments can be separated.

(Conventional technology) The conventional paper container that can be divided into small portions is
Publication No. 177321, Publication No. 180116, Publication No. 180116, Publication No. 180116, Publication No. 180116, Publication No.
The one described in Publication No. 57-11002 and the like is known.

The above-mentioned conventional paper carton has an upper surface portion attached to the upper surface of the parallel storage sections.

(Problem that the invention aims to solve) Therefore, since the conventional paper containers mentioned above do not have a series of lower parts on the bottom, they are not strong, and the bottom may fall off when a heavy product is placed in the storage compartment.
The bottom shakes when you carry it around, making it difficult to handle. Further, since the structure of the storage section is complicated, it can only be assembled manually, and continuous assembly, product storage and sealing, etc. cannot be performed by a machine. Furthermore, since the shape of the storage section is complicated, there is a lot of waste when cutting the raw material cardboard or corrugated paper, resulting in a large economic loss. In addition, since the upper and lower sides of the side walls of the storage section are not covered with adhesive, gaps are created between the upper side and the top surface, and between the bottom side and the bottom surface, allowing dust, dirt, and other foreign matter to enter the storage section. However, especially in the case of food products stored in the storage section, the product becomes soiled and loses its commercial value. or,
When displaying products, one side of the top surface attached to the top surface of the storage section is opened to make the product inside the storage section visible from the outside, and then the top surface of the storage section must be closed again with the top surface section. I can't.

(Means for solving the problem) The present invention was proposed in view of the above, and has an open upper and lower surface, an upper sleeve extending on the upper sides of two opposing side walls, and a lower sleeve on the lower side. A plurality of storage sections each having an extended sleeve are arranged side by side so that the side wall portions having upper and lower sleeve sections are in close contact with each other, and a cut section is formed between adjacent storage sections, and a fold line is inserted from both sides of the storage section. The upper surface and the lower surface of the plurality of storage sections are formed by extending the adhesive part and providing folding lines parallel to the folding lines at intervals approximately equal to the thickness of the paper in the storage sections on the inside of at least one of the folding lines. The lower surface is adhered in series, and the adhesive portions of the upper and lower surfaces are fixed to the outer surface of each storage section.

(Example) The present invention will be explained below with reference to embodiments of the drawings.

FIG. 1 shows the unfolded state of a storage section 1 in which products are stored, with four side walls 2 . Therefore, by folding each fold line a inward at 90 degrees and fixing the fixing piece 3 to the inner surface of the side wall 2 at the other end with adhesive, staples, etc., a rectangular cylindrical storage with open upper and lower surfaces can be created. Part 1 can be assembled.

In addition, in order to protect the upper and lower edges of the storage section 1, an upper sleeve piece 4 is extended on the upper sides of the two opposing side walls 2, 2, and a lower sleeve piece 4 is provided on the lower sides of the two opposing side walls 2, 2. Extend piece 5. Therefore, when the upper sleeve pieces 4 and lower sleeve pieces 5 of the storage section 1 assembled into a rectangular tube shape are folded inward, the upper and lower edges of the storage section 1 are reinforced by the sleeve pieces 4 and 5. will be done.

FIG. 2 is a perspective view of the storage sections 1 assembled as described above, arranged side by side on the left and right, with the upper surface section 6 and the lower surface section 7 on the upper and lower surfaces of the plurality of storage sections 1 arranged closely in parallel. to adhere to. The upper surface part 6 and the lower surface part 7 have the same configuration as shown in FIG. Another adhesive part 10 is extended through the fold line c and the fold line c'. The above-mentioned fold lines c and fold lines c' are formed in parallel with a narrow interval equal to the thickness of the paper in the storage section 1.

Cutting portions 11 are formed in the upper surface portion 6 and lower surface portion 7 described above so as to cross the width direction.

If the upper surface portion 6 and lower surface portion 7 are made of cardboard, the cutting portion 11 is formed by two narrow perforations 1 extending parallel to each other.
2 and 12, an H-shaped folded part 13 is formed in the center. However, if the upper surface part 6 and the lower surface part 7 are made of corrugated paper, the cutting part 11 can be constituted by the above-described H-shaped notch part 13 and a narrow tape attached to the back surface.

The embodiment shown in the drawings shows a case in which two storage sections 1, 1 are arranged closely side by side, and an upper surface section 6 and a lower surface section 7 are sequentially attached to the upper and lower surfaces of both storage sections 1, 1.
Therefore, the cutting portion 11 is connected to the upper surface portion 6 and the lower surface portion 7.
It is sufficient to form only one in the center of the .

However, when three or more storage units 1 are arranged in parallel and the upper and lower surfaces are attached to the upper and lower surfaces,
Cut parts 1 for each width of the storage part 1 on the top and bottom parts.
1 will be formed.

In order to assemble a paper container that can be divided into smaller pieces using the storage section 1, upper surface section 6, and lower surface section 7 formed as described above, the storage sections 1 and 1 are assembled into a rectangular tube shape with the upper and lower surfaces open as described above. are arranged closely side by side, and the lower surface part 7 is applied to the lower surface of each storage part 1, 1 to form a flat part 8.
Glue the open lower surface of the storage part 1 with the adhesive parts 9 and 1.
0 upward at fold lines b and c and fixed to the outer surface of each storage section 1. Adhesives, staples, hot melt, etc. may be used to secure the adhesive parts 9, 10 to the outer surface of the storage section.

After the open lower surface of each storage section 1 is covered with the lower surface section 7 in a series as described above, the product is placed in each storage section 1, the upper surface section 6 is applied to the open upper surface of each storage section 1, and both adhesive sections 9 , 10 are bent downward along fold lines b and c and fixed to the outer surface of each storage section 1. This fixing can also be done using adhesives, staples, hot melt, etc., as in the case of the lower surface part described above.

If you assemble the paper carton in this way, each storage section 1
... are fixed in series by the upper surface part 6 and the lower surface part 7, so that the strength is extremely high. Therefore, there is little risk that each storage section will be separated or damaged during storage, transportation, etc., and it is not only easier to handle, but also the packaging and transportation costs can be reduced.

On the other hand, in a store, for example, the storage section is separated and displayed or sold. In this case, insert your fingertip into the notch 13 of the cutting part 11 of the upper surface part 6, and cut the part surrounded by the H shape of the notch 13 into the cutting part 11.
1 along one half and tear it to the edge of the adhesive part 9. Further, when the other portions of the cut portion 13 surrounded by the H-shape are pulled up and torn to the edge of the adhesive portion 10 in the same manner as described above, the upper surface portion 6 is separated from the cut portion 11 to the left and right. The cut portion 11 of the lower surface portion 7 is also separated into left and right parts in the same manner as the upper surface portion 6 described above.

Therefore, each storage section 1 is separated while its upper and lower surfaces are closed by the upper and lower surfaces.
Products in separate individual compartments can be sold. When displaying the products in the storage section 1, the adhesive section 10 can be peeled off from the outer surface of the storage section 1, and the flat section 8 can be lifted to open the inside of the storage section 1.

Furthermore, when the adhesive part 10 is folded downward along the folding line c', the flat part 8 becomes shorter by the thickness, as shown in FIG. be able to.

Note that the embodiment shown in the drawings shows the case where adhesive parts are extended on both side edges of the upper surface part and the lower surface part, but the adhesive parts are extended on both the left and right edges of the upper surface part and the lower surface part, It may be fixed to the top and bottom of the outer surface. Furthermore, although the embodiment of the drawings shows a case in which two storage sections are arranged side by side, three or four or more storage sections may be arranged side by side and integrated at the upper and lower surfaces.

(Effects of the invention) In summary, according to the invention, the upper and lower surfaces of a plurality of closely spaced storage units are covered in series at the upper and lower parts, and extend from the side edges of the upper and lower parts. Since the adhesive part is fixed to the outer surface of each storage section, the strength of each storage section is high and there is no possibility of separation or damage, and the bottom surface does not move, making it easy to handle when carrying. In addition, since the upper and lower sleeve pieces are formed on the upper and lower sides of the side wall of the storage section, respectively, the space between the upper side and the upper surface and between the lower side and the lower surface is closed, allowing dust and dirt to flow into the storage section. Since it does not allow dust to enter, it can be effectively used especially for packaging foodstuffs. In addition, when displaying products, if one side of the top surface attached to the top surface of the separated storage section is opened and the product inside the storage section is visible from the outside, the adhesive part can be folded downward along the fold line. If you insert it inside from the open top surface, you can close the top surface of the storage section again with the top surface. In addition, since the storage section, upper surface section, and lower surface section are easy to assemble, they can be assembled, stored, and sealed continuously by mechanical means.
The subdivision work is also extremely easy, and the practical value is extremely high.
