Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a packaging box top lid provided with an adhesive piece, which facilitates sealing and opening of the packaging box, and also allows the packaging box to be reused. This made it possible to do so in beautiful condition.

[Problems to be solved by conventional technology and ideas]

Conventionally, methods such as gluing, stitching, and taping have been used to seal the top lids of packaging boxes such as cardboard boxes and paper cartons. Although these methods achieve the purpose of sealing, when reusing the packaging box after opening, the appearance is poor due to peeling of the paper and stitch holes, and it is necessary to re-glue or tape the seal. These operations are required. Furthermore, depending on how the seal is sealed, it may be possible to remove or replace part of the contents by skillfully opening the seal.
Alternatively, in the case of foods, etc., harmful substances may be added, which poses a safety problem.

[Means for solving problems]

Seal the packaging box by solving the above problems.
In this invention, when sealing the packaging box, the upper side and An adhesive strip with perforations is placed near both ends of the pair of upper lid flaps, the adhesive strip is attached to the lower flap to seal the packaging box, and the adhesive strip is inserted through the perforation. Separate the base of the adhesive piece and open it,
When the packaging box is used unsealed, the base of the adhesive piece with or without an adhesive piece is inserted through a notch provided in the lower flap.

[Effect]

In this invention, the shape, size, number, and position of the adhesive pieces to be placed on the upper lid flap should be determined as appropriate depending on the type and size of the packaging box, the contents of the packaging, etc. I can do it. The same applies to the shape and size of the adhesive piece base, but the number and arrangement position thereof are determined by the adhesive piece. It goes without saying that the incisions to be provided in the lower flap must be large enough to allow insertion of the adhesive piece base, and their number and position are determined by the size of the adhesive piece base. The cuts may be made in one direction, but in order to smoothly insert the base, it is preferable to make the cuts in three directions to form a U-shape.

To seal the packaging box according to the present invention, each adhesive strip is applied with adhesive and attached to the lower flap. Make sure to adhere firmly as the adhesive piece will not be removed later. When opening the package, cut the adhesive strip and base from the perforations. Next, when the packaging box is to be reused, it is sufficient to simply insert the base of the adhesive strip into the cut in the lower flap. By doing so, by simply leaving the adhesive piece attached to the lower flap, there will be no peeling of the paper or stitch holes, and it can be reused in a beautiful state. Therefore, according to the present invention, if the adhesive piece of the upper flap remains attached to the base and is attached to the lower flap, it indicates that the package is unopened.
If only the adhesive piece is separated from the base and remains on the lower flap, it can be seen that the seal has been opened, so that it can be clearly shown whether the seal has been opened or not. It goes without saying that if sealed packaging is not performed or if unsealed packaging is used before sealed packaging, the above-mentioned reusable packaging can be performed with the adhesive strip attached.

〔Example〕

The following will explain the embodiments shown in the drawings.

Figure 1 is a sketch showing the upper lid of a packaging box on which the adhesive strip of the present invention is installed, with a pair of upper flaps 1
The four adhesive strips 3 located near both ends of the flap are attached to the lower flap 2, indicating that the packaging is completed.
There is a perforation 5 between each adhesive piece 3 and the base 4, from which the bag is separated and opened.

FIG. 2 shows a developed view of the packaging box, that is, the shape of the blank sheet. In the figure, the upper flap 1 is provided with an adhesive piece 3 and its base 4, and the lower flap 2 is provided with diagonal U-shaped notches 6 on three sides into which the adhesive piece base 4 is inserted. ing. 7 is a fold that is slightly bent downward when the adhesive piece base 4 is inserted into the cut 6.

FIG. 3 is a sketch showing how to reuse a packaging box that has been used once. In the upper right A, the adhesive piece base 4 separated from the adhesive piece 3 is inserted into the notch 6 made in the lower flap 2. However, the lower left corner shows the state in which the insertion has been completed. The cut-off adhesive piece 3 remains attached on the lower flap 2.

Figure 4 shows the base 4 without using the adhesive piece 3.
This is a sketch showing how to pack the lid by inserting it into the notch 6 of the lower flap 2 while still attached, and the packaging top lid of the present invention can also be used in this way. The upper right A shows the insertion, and the lower left B shows the state after insertion.

[Effect of idea]

As is clear from the above explanation, by using the top lid with the adhesive piece according to the present invention, it is not only easy to seal and open the packaging box, but also it is possible to reuse it in a beautiful state. There are many things that can greatly contribute to improving packaging methods, such as being able to clearly indicate whether or not the package has been opened.
