Description

TECHNICAL FIELD The present invention relates to a packaging box with a handle.

2. Description of the Related Art Conventional technology and its problems Conventionally, as a packaging box with a handle applied to the packaging of cakes and the like, there has been proposed a packaging box which can be assembled and deployed as shown in FIG. This conventional type is convenient because the cake can be put in and out with the box completely unfolded, but the front and rear, left and right side plates (a), (b), (c), and (d) are all fulcrum at the base end folds. Since it is configured to be able to rotate between 0 to 180 °, for example, at the time of assembly, for example, one set of side plates that has been initially erected is supported by hand while another set of side plates is erected and assembled. However, this is not suitable for cake packaging where quick assembly at the store is desired, and supports each side plate in an upright state. Since there is nothing to be a skeleton, there is a problem that there is concern about the strength of the box in the assembled state.

The present invention has been made for the purpose of eliminating such conventional problems.

Means for Solving the Problems The present invention comprises front and rear side plates connected to the front and rear side parts of a bottom plate, and the front and rear side plates have locking plates with locking holes at the upper end and overlapping pieces on the left and right side parts. Each of the overlapped pieces is adhered and fixed to both left and right sides of the bottom plate at the lower end in a state of being bent inward by 90 ° so as to form a corner in cooperation with the side plate, and Each overlapping piece is formed with an intermediate fold that allows pivoting movement from the standing position with the base folds of the front and rear side plates as fulcrums to the folding position on the bottom plate, while one of the left and right sides of the bottom plate is formed. The front and rear side plates, which are superposed on the outer side of the overlapped piece in the standing state and are rotatable outward from the standing position with the lower end fold as a fulcrum, are connected to the upper part of the front and rear side plates. , A half-split lid plate with a hand-held handpiece is connected to each other, and the locking plates are locked at the front and rear sides of the upper end of each handpiece. According to Hisage earnest packing box, wherein the engaging portion is formed against.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

As apparent from the development view of FIG. 1, the packaging box of the present invention comprises a bottom plate (1), front and rear, left and right side plates (2) (2), which are connected to the plate (1) through folds, (3) and (3) are provided.

The front and rear side plates (2) and (2) have locking plates (4) with locking holes (41) formed at the upper ends through folds, and intermediate folds formed at both sides through folds. Each of the overlapping pieces (5) with eyes (51) has a left and right side plate (3) at the lower end of each overlapping piece (5).
The size margin (52) cut out from (3) is linked through the folds.

On the other hand, the left and right side plates (3) and (3) have half-lid lid plates (6) with a palm-shaped handpiece piece (7) connected to the upper end through folds. Locking portions (71) (71) that lock with the locking holes (41) of the locking (4) are formed on both sides. Incidentally, the half-split lid plate (6) can be formed with a polymerized tongue piece (62) punched out from a U-shaped cut (61) as usual.

From the unfolded state shown in FIG. 1, raise the front and rear side plates (2),
Further, the polymerized pieces (5) and (5) are bent inward from both sides of the plate (2) by 90 °, and the lower end of each polymerized piece (5) is attached to the adhesive margin (5).
2) In the four corners of the top surface of the bottom plate (1), the hatched parts (1
By sticking to 1), the product of the present invention can be obtained as shown in FIG.

In the state shown in FIG. 2, when the front and rear side plates (2) and (2) are rotated inward with the base end folds (21) and (21) as fulcrums, the overlapping piece (5) is folded in the middle as it rotates. It will be folded at the eye (51). Thus, the front and rear side plates (2) and (2) can be rotated in the range of 0 to 90 °, and the rising position or the folding position on the bottom plate (1) can be selectively set.

Therefore, the front and rear side plates (2) are not folded from the standing state shown in FIG. 2 to the bottom plate (1) as shown in FIG. ) (6) is folded on the bottom plate (1) to obtain a compact folded state as shown in FIG. The present invention is transported and stored in this compact folded state.

When assembling the box from the folded state shown in Fig. 4,
The half cover plates (6) and (6) are unfolded (see FIG. 3), and then the front and rear side plates (2) and (2) are raised.

In the standing state, the front and rear side plates (2) and (2) are slightly inclined forward as shown in FIG. 2 due to the springback tendency of the intermediate fold (51) of the overlapped piece (5). By the function of the polymerized piece (5) that forms the, it is substantially restrained in the forward tilted posture. In the state shown in FIG. 2, when the left and right side plates (3) are rotated in the standing direction from the deployed position shown in the figure with the base folds (31) as the fulcrum, the plates ( Both side parts of 3) are superposed on and adhered to the superposed piece (5) and cannot be further rotated. That is, the overlapping piece (5) functions as a position regulating stopper that stops the rotation of the left and right side plates (3) and (3) at the standing position (90 °) during the standing operation. In addition, due to the polymerization adhesion of the left and right side plates (3) to the overlapped piece (5) at the standing position, the overlapped piece (5) is vertically extended regardless of the springback tendency of the intermediate fold (51). The side plates (2) and (2) are automatically corrected from the forward tilted posture to the vertical posture. Therefore, the box main body is assembled by a so-called one-touch operation of simply erecting the left and right side plates (3) and (3) without requiring troublesome work such as supporting the front and rear side plates (2) and (2) with hands. Is possible.

After completing the assembly of the box body, after assembling the lid part from the half-split lid plates (6) and (6) as usual, and further assembling the joint type handle from the handle pieces (7) and (7), By locking the locking part (71) at the upper end of the hand piece (7) in the locking hole (41) of the locking plate (4) in the palm-closed state, all the assembly operations are completed as shown in FIG. Then, a packaging box with a handle is obtained here.

The packaging box with a handle assembled in this way has a structure in which the front and rear side plates (2) cooperate with the overlapping pieces (5) to form a corner so that they cannot fall outward from the standing state. Since the superposed superposed piece (5), and further the left and right side plates (3) and (3) are supported by the front and rear side plates (2) in an upright state,
It is possible to assemble a box that is stable in strength.

The cake is put in and taken out of the box in the state shown in FIG. The standing front and rear side plates (2) and (2) are in a forward leaning posture, but are restrained in the forward leaning posture by the action of the overlapping piece (5).
Further, there is a space (D) between the front and rear sets of polymerized pieces (5) and (5).
The bottom plate (1) is held through this space (D)
The cake can be placed on top or the cake placed on the bottom plate (1) can be taken out of the box. Since the cake can be put in and taken out of the box from the lateral direction, it is more convenient than the method of going up and down.

As described above, according to the present invention, the cake can be put in and out from the lateral direction, is convenient, and can be assembled by one-touch operation. Can provide box.
