It is to be sealed as shown in FIG.

The A-1 type cardboard box 30 described above
Other than the cardboard boxes 50 and 60, the sealing method is as follows.
If there is an item to be stored in the middle of distribution, the box can be easily opened.For example, at the store, take out the warranty for the stored item from the box, re-write the warranty after listing the store name. It is widely used as a form for storing and sealing.

[0010]

The above-mentioned method of sealing the cardboard box has the following drawbacks. That is, the A-1 type cardboard box 30 cannot be opened unless the sealing tape 35 is cut or the sealing tape 35 is peeled off and removed. If the sealing tape 35 is cut, another tape is required to reseal it. If the sealing tape 35 is peeled off, the liner on the surface of the cardboard is broken and it becomes unsightly. I need a tape.

Also, the V-shaped lock cardboard box 50 is
Inserting pieces 53a, 53b of the flaps 33a, 33b,
When inserting 54a and 54b, the tip is pushed into the inside of the box until the tip becomes horizontal so that the flap is further extended. Therefore, when the tip comes into contact with the contents when it sunk, the tip cannot be pushed any further and cannot be sealed. Therefore, a space is required for the outer shape of the contents.

For example, since the tip of the flap comes into contact with the cushioning material for protecting the contents and cannot be pushed in sufficiently, it is necessary to provide a "niger" space at the contact portion of the cushioning material.
There will be restrictions on the cushioning material design. If the insertion pieces 53a, 53b, 54a, 54b and the insertion grooves 51a, 51b, 52a, 51b do not match in shape, the tip may be broken or the ends of the groove may be broken when the flap is inserted. For this reason, since the shape that is easy to insert is devised, on the contrary, it is easy to pull out, and there is a drawback that it is opened during distribution. Further, the B type cardboard box 60, due to its flap shape, has a material effective utilization rate at the time of box manufacturing remarkably lower than that of the above cardboard box, resulting in a high material cost.

The present invention is an A-1 type corrugated cardboard box which does not require a sealing tape, eliminates the difficulty of inserting the flap of the square-shaped cardboard box and makes it easy to pull it out, and uses an expensive material for the B type cardboard box. A reliable sealing method and device that can be made inexpensive are provided.

[0014]

According to the method for sealing a corrugated cardboard box of type A-1 of the present invention, a pair of flaps serving as outer lids of the upper lid are provided with sealing flaps at both ends thereof, and a pair of flaps serving as inner lids. It is characterized in that it is sealed while being inserted between the notches provided in each.

Further, the closure device is provided with flaps serving as inner and outer side lids forming a bottom lid provided on one side portion of each peripheral side wall plate of the box main body and another side portion of each peripheral side wall plate of the box main body. A provided with flaps serving as both inner and outer lids that form the upper lid provided
In the -1 type cardboard box, a pair of flaps that are outer lids that form the upper lid are provided with sealing flaps at both ends thereof, and a pair of flaps that are inner lids are provided.
