Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a box structure in which two independent boxes can be lined up and connected to each other.

[Conventional technology]

This type of box is very convenient because it can reduce the amount of boxes to be handled by half during transportation and storage by connecting them together in pairs.

Conventionally, this type of box has a structure shown in the exploded view of FIG. 9 (Utility Model Application No. 57-88736).

The basic structure of this box is that a rectangular cylindrical box body is formed by a pair of opposing side walls 11 and a pair of opposing end walls 12 provided at both ends of the side walls 11. An outer flap 14 is provided on each of the upper and lower sides, and an inner flap 13 is provided on each of the upper and lower sides of the end wall 12.

Then, on both sides of one side wall 11 of the side wall 11 forming the box body of the box, there is a side wall 1 on one side.
A cut 15 is formed from the upper side of 1 to a middle height, and a locking piece 16 is connected to the end wall 12 on the other side.
The two boxes are connected to each other by butting them together as shown in FIG. 10 and inserting the locking piece 16 of one box into the cut 15 of the other box. It is becoming more and more common.

[The problem that the idea attempts to solve]

However, in the box with the above structure, the connection cut 1
5 is formed over the middle height from the upper side of the side wall 11 forming the box body, so this cut 1
There is a problem in that the strength of the side portions of the side walls 11 on which the side walls 11 are formed, particularly the strength against stress in the vertical direction, is weak.

Further, if the cut 15 is formed in the box body, there is a problem that dust etc. may enter the box through the cut 15 when the box is used alone.

In addition, the box with the above structure has a locking piece 16 for connection.
As shown in FIG. 9, since the end wall 12 of the box body is formed to extend laterally, there is also the problem that the amount of material used to form the box increases significantly.

Therefore, this idea was developed without creating cuts in the box body or increasing the amount of material used for the box.
The technical problem is to be able to connect two boxes to each other.

[Means to solve the problem]

In this invention, in order to solve the above technical problem, the box was constructed as follows.

That is, a rectangular cylindrical box body is formed by a pair of opposing side walls and a pair of opposing end walls provided at both ends of the side walls, and inner flaps are provided on the upper and lower sides of the side walls, respectively. In the box, at the corner portions of the side walls on both sides of at least one outer flap,
A locking piece approximately the same size as the notch is provided in series on the side of the inner flap adjacent to at least one notch of the outer flap. A notch is formed at the boundary between the inner flap and the inner flap to fit into the notch of the outer flap when the locking piece is folded inward together with the inner flap.

[Effect]

After butting two boxes with the above structure so that the outer flaps with cutouts face each other, and then folding the inner flaps with continuous locking pieces inward, the notches of the locking pieces will be removed from the outside. It fits into the lower end of the notch in the flap, connecting the two boxes to each other.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The box A according to this invention is made of thick paper such as cardboard, and basically consists of a rectangular cylindrical box body, a pair of opposing side walls 1, and a box provided at both ends of the side walls 1. It is formed by a pair of opposing end walls 2, with outer flaps 4 provided on the upper and lower sides of the side wall 1, and inner flaps 3 provided on the upper and lower sides of the end wall 2, respectively.

Corner portions 4 of the side walls 1 on both sides of the outer flap 4 located above and below one of the pair of side walls 1
A cutout portion 5 is formed at each location.

A locking piece 6 having approximately the same size as the notch 5 is formed on one side of the inner flap 3 adjacent to the outer flap 4 in which the notch 5 is formed. This locking piece 6 can be formed using a punched portion of the notch 5 of the outer flap 4. Furthermore, a notch 7 is formed at the boundary between the locking piece 6 and the inner flap 3, which fits into the notch 5 of the outer flap 4 when the locking piece 6 is folded inward together with the inner flap 3. has been done.

When connecting two boxes A configured as described above, first, as shown in FIG.
When the outer flaps 4 with the locking pieces 6 are butted against each other and the inner flaps 3 with the locking pieces 6 are folded inward, the notches 7 of the locking pieces 6 are aligned with each other as shown in FIG. It fits into the lower ends of the notches 5 of the outer flaps 4 of the two butted boxes A.
In this state, the two boxes A remain connected to each other. After this, the inner flap 3 without the locking piece 6 is folded over the locking piece 6 of the other box A as shown in FIG. When the flaps 3 are folded over, one of the upper and lower surfaces of the two boxes A is closed. Next, as shown in Figure 6, the two connected boxes A
After inverting and storing the item in box A in this state, fold in the inner flap 3 with the locking piece 6, the inner flap 3 without the locking piece 6, and the outer flap 4 in this order in the same way as above. , the state as shown in FIG. 7 is reached, and the packaging is completed.

In addition, when dividing the two boxes A connected in the above manner, it is sufficient to cut the boundary portion between the locking piece 6 and the inner flap 3 using a cutter.

[Effect of idea]

As described above, according to this invention, the connecting notch and the locking piece can be provided on the outer flap and the inner flap that are connected to the box body, respectively, so deterioration of the strength of the box body can be prevented. At the same time, there are no gaps where dust or the like can enter the box body. Further, since the locking piece for connection can be formed by using the punched part of the notch provided in the outer flap, there is also an effect that there is no waste of material used for the box.
