In addition, a fold line K1 parallel to the ruled line S at the upper end of the front side wall 3 and having a length corresponding to the width of the insertion slot 13 is formed, and the inner flap 14 has the fold line K1 as a base end. A concave cut 15 extending to the front side wall 3 and the inner flap 14 is formed to form a lock piece 16 bent into a hook shape, and the ruled line S continuous to the left and right of the cut 15 is formed. A slit 17 corresponding to the width of the insertion piece 12 is formed in the. Then, while the upper opening 7 is closed by the outer flap 8, the insertion piece 12 is inserted into the slit 17, and the tip of the lock piece 16 (the portion that was a part of the inner flap 14) is inserted into the insertion opening 13. It is designed to be inserted and to lock the outer flap 8.

The inner flaps 9 and 9a are slightly narrower than the left and right side walls 5 and 6, and are bent inward (arranged on the upper opening 7) at the ruled line S at the upper ends of the left and right side walls 5 and 6, and The front ends have such a length that they overlap each other, and the inner flaps 9 and 9a can be transformed into a handle H that is center-folded and outwardly protruded so that the back surfaces thereof are joined. A pair of parallel fold lines K2 are formed in the middle folding part of the inner flaps 9 and 9a in the width direction thereof, and in the state where the inner flaps 9 and 9a are transformed into the handle H, they correspond to the outer surface L of the handle H. The front end side M of the inner flaps 9 and 9a corresponding to the inner side surface M of the handle H is formed to be slightly longer than the base end side L of the inner flaps 9 and 9a. The longest distal portion M1 is slightly wider than the inner flaps 9 and 9a and has the same width as the left and right side walls 5 and 6. When the inner flaps 9 and 9a are deformed by the handles, the inner surfaces of the left and right side walls 5 and 6 are upper portions. It abuts against. Further, at the approximate center of the proximal side L and the distal side M of the inner flaps 9 and 9a, there are provided handle holes 18, 18a, 19 and 19a which are positioned so as to match in the deformed state of the handle. The handle holes 19 and 19a provided on the front end side M of the inner flaps 9 and 9a are formed by hollowing out a long elliptical shape in the lateral direction.
The holding holes 18 and 18a provided on the proximal end side L of the same have the same shape as the above, and a part of the outline thereof (in the state of being transformed into the handle H) is not broken and only the horizontally long straight line portion is not cut. K3, the elliptical plates 20 and 20a existing in the handle holes 18 and 18a are connected to the inner flaps 9 and 9a through the fold line K3, and the inner flaps 9 and 9a are transformed into the grip H, The elliptical plates 20 and 20a are bent at the folding line K3 and pushed out from the handle holes 18 and 18a, and the other handle hole 19 and
The carton 1 is carried by inserting it through the inside of 19a and passing through the handle holes 18, 18a, 19, 19a. or,
On the tip side M of the inner flaps 9 and 9a, projecting pieces 21 and 21a that support the outer flap 8 in the closed state are formed by cutting so that they can be raised in the handle deformed state. This protrusion 21, 21
a is a pair of left and right C-shaped incisions C continuous from the end of the horizontally long straight portion below the handle holes 19 and 19a (in the state of being transformed into the handle H) toward the most distal end portion M1, and the incision C of the incision C. A fold V formed by forming a perforation on the line connecting the ends, and when the inner flaps 9 and 9a are deformed by the handle, the protrusion 2
When the 1, 21a are bent at the fold line V and are raised at right angles to the inner side surface M of the inner flaps 9, 9a, the protruding pieces 21, 21a are arranged horizontally on substantially the same plane as the upper ends of the left and right side walls 5, 6. Is set to.

The carton 1 having the above structure is flatly folded so that the diagonal portions TN of the bottom portion 2 come into contact with each other and stored or transported. In use, the ridge line (ruled line C) between the front side wall 3 and the right side wall 6 and the ridge line (ruled line C) between the rear side wall 4 and the left side wall 5 are pushed so that the diagonal part TK of the bottom part 2 approaches, and By forming 2 into a square shape, a three-dimensional box is formed. Then, the inner flaps 9 and 9a are abutted on the inner surface upper portions of the left and right side walls 5 and 6 by center-folding the tip side M of the inner flaps 9 and 9a along the folding line K2, and the inner flaps 9 and 9a are abutted on the left and right side walls 5 and 6. While being deformed into a handle H that stands upright, the inner flap 14 is folded into the carton 1 along a ruled line S that serves as a boundary with the front side wall 3.
The contents are stored in the carton 1 in the assembled state. In particular, when a synthetic resin bag F is arranged inside the carton 1 such as when the carton 1 is used as a medical waste collection box, the collection port side of the bag F stands on the left and right above the carton 1. The bag F is set so that it is folded over so that the bag F can be covered with the bag F so that the bag F does not fall into the carton 1. After storing the contents in the carton 1, the outer flap 8
When sealing with, the protrusion 2 provided on the inner side M of the handle H
1 and 21a are caused, and the projecting pieces 21 and 21a are attached to the left and right side walls 5, 6
The upper opening 7 is horizontally arranged on the substantially same plane as the upper end of the, the upper opening 7 is closed by the outer flap 8, and the insertion piece 12 is slit.
17 and the tip of the lock piece 16 is inserted into the insertion port 13 to lock the outer flap 8. In such a state, the left and right sides of the outer flap 9 are supported by the projecting pieces 21 and 21a, and the tip end side of the outer flap 9 is supported by the inner flap 14, so that other contents containing the outer flap 8 can be accommodated. You can stack carton 1. Further, when carrying the carton 1, the elliptical plate 2 is inserted through the carrying holes 18, 18a on the outer side surface L of the handle H.
Bend 0 and 20a along the fold line K3 and push it out, and insert it into the other handholes 19 and 19a.

In summary, according to the present invention, since it is possible to fold the center of the pair of left and right inner flaps 9 and 9a so that the back surfaces of the inner flaps 9 and 9a are joined to each other to be deformed to the outwardly projecting handle H, the box H of the box can be changed. The handle H can be formed outside the carton 1 in a sealed state by the outer flap 8 without providing a handle hole on the left and right side walls, and can be easily carried. Further, since the handle H is configured by folding the inner flaps 9 and 9a in two, the strength of the handle H is improved and the handle holes 18, 18a, 19 and 19a provided so as to penetrate the handle H are provided. The grip of the hand to be inserted can be achieved in a good condition, and the handle H once deformed can be deformed into the normal inner flaps 9 and 9a as needed to re-carton the carton 1.
It can also be housed inside. Moreover, since the structure is simple as described above, it does not require any effort to be transformed into the handle H, and since the handle holes 18, 18a, 19, 19a are provided in the inner flaps 9, 9a, the box itself Does not affect strength.

At the front end M of the inner flaps 9 and 9a corresponding to the inner side surface M of the handle H, protrusions 21 and 21a for supporting the outer flap 8 in the sealed state are formed so as to be freely incised and formed. Even when the inner flaps 9 and 9a of the above are deformed into the handles H, the left and right ends of the outer flap 8 in the sealed state can be supported by raising the protruding pieces 21 and 21a, and the contents can be accommodated on the closed outer flap 8. Even if other stored cartons 1 are stacked and stored, the outer flap 8 does not fall inside,
The loaded state can be maintained.

The projecting pieces 21 and 21a are handle holes provided on the inner side surface M.
Since a pair of left and right incisions C continuous from 19 and 19a and a fold V connecting the ends of the incisions C are formed, the handle hole 19,
Part of the outline (outer shape) of 19a (horizontal straight line portion below the handle holes 19 and 19a) is shared by the tips of the projecting pieces 21 and 21a, and when the projecting pieces 21 and 21a are caused, they are already opened. A horizontally long straight line portion below the handle holes 19 and 19a (projection pieces 21 and 21)
Just put your hand on (the tip of a) and pull down the part,
Projecting pieces 21, 21a protruding at right angles to the inner side surface M at the fold line V
Can be easily formed.

An outer flap 8 in a sealed state is provided on the upper end of the front side wall 3.
Since the inner flap 14 for supporting the tip of the outer flap 8 is provided, even when the left and right inner flaps 9 and 9a are transformed into the handle H, the outer flap 8 can be closed without being dropped into the inside, and another carton containing the contents can be closed. It is possible to stack and store 1 and also projecting pieces 2 that support the left and right ends of the outer flap 8.
By 1 and 21a, four sides of the outer flap 8 in the sealed state are supported (the tip is the inner flap 14, the left and right ends are the projections 21 and 21a, and the base ends are connected to the rear side wall 4). The strength with which the other carton 1 is loaded and stored on the outer flap 8 can be further improved, and the loaded state is not disturbed and is safe, and the practical effect thereof is great.
