Fourthly, handles 9a and 9b which are vertically overlapped with each other in an upright position when the top plates 8a and 8b are overlapped are positioned at the end of the cutout portion B of the fixed top plate 8a and the center of the tip of the movable top plate 8b. It is characterized by being provided respectively.

Fifth, at least one of the end of the notch B of the fixed top plate 8a and the tip of the movable top plate 8b is extended so that the tongue portions 19a and 19b are protruded. , 19b are engaged with the movable top plate 8b side or the fixed top plate 8a side to form a restricting portion.

[0008] Sixth, at the left and right base ends of the handle 9b on the movable top plate 8b side, the opening A is closed by the movable top plate 8b, and the handle 9b is set up. , 18 are provided with regulating portions for engaging the inner ends of the movable top plate 8b to regulate the vertical movement of the movable top plate 8b.

[0009] Seventh, the claw portions 22a, 23a, and 24a protrude from the peripheral end of the rear wall 7 or a constituent member of the rear wall 7, and at least one of the side walls 3, 4 and the top plate 8a or the bottom plate 2, Claw holes 22b, 23b, 24b for inserting and locking the claw portions 22a, 23a, 24a when assembling the box body 1 by extending the rear wall 7 from the folded state are provided at the end on the side of connection with the rear wall 7. The structure is such that the rigidity of the rear wall 7 is maintained when the box is assembled.

[0010]

[Embodiment of the invention]

 The drawings show one embodiment of the present invention. A box 1 made of paperboard has a rectangular or square bottom plate 2 with left and right side walls 3, 4 and front and rear walls 6, 7 on two opposite sides of the left and right and front and back. Each is connected so that it can be bent. The top plate 8a (fixed top plate) is provided with a left-right handle 9a that can be folded and raised at the center, and is connected to the left and right side walls 3, 4 and the rear wall 7.

As shown in the figure, the rear wall 7 is configured so as to be engaged and disengaged from each other and divided so as to be assembled and foldable. One rear wall piece 7a is provided at the rear end of the bottom plate 2 and the other rear wall piece is provided. 7b is connected to the rear end of the fixed top plate 8a in a flap shape, and both pieces 7a and 7b have substantially the same shape when the box is extended. On the other hand, adhesive pieces 11a and 11b formed of flaps having the same trapezoidal shape are also provided at the rear ends of the side walls 3 and 4 so as to be freely bent.

At the end of each of the rear wall pieces 7a and 7b, bonding pieces 12a and 12b whose inner surfaces are bonded to the surface sides of the above-mentioned bonding pieces 11a and 11b are connected to each other through crests of a mountain shape. I have. The adhesive pieces 11a and 12a and the adhesive pieces 11b and 12b are adjacent to each other, and the glued portions indicated by the hatched portion (inner surface) and the hatched portion (front surface) in FIG.

The rear wall pieces 7a and 7b are bonded to each other by bonding the bonding pieces 11a and 12a and the bonding pieces 11b and 12b to each other to form a bonding structure commonly called “hell bonding”. In the assembled state, they are extended in the form of a plate as shown in FIG. 4, and in the folded state, the whole is folded as shown in FIG.

On the other hand, an opening A which is opened and closed by a front wall 6 is provided on the front side of the box body 1, and the bottom plate 2 side and the fixed top plate 8a side are overlapped in a plate shape when folded. . At the front ends of the left and right side walls 3, 4, flaps 13, 14, which are bent inward at right angles when the opening A is closed, are continuously provided. Further, on the right end (FIG. 1) of the fixed top plate 8a, an adhesive piece 16 (a hatched portion indicates a glued surface) for connecting and fixing the fixed top plate 8a and the upper end of the right side plate 4 by bonding is provided in a bendable manner. It has been done.

Further, a flap-shaped movable top plate 8b is connected to the upper end side of the front wall 6 and overlaps the front half of the fixed top plate 8a when the front wall is closed, and the movable top plate 8b is fixed to the fixed top plate 8a. In the state where the movable top plate 8b is superimposed on the fixed top plate 8a, there is provided a regulating portion for regulating the movable top plate 8b in the vertical direction. The configuration of the restriction unit will be described later in detail.

At least the left and right central sides of the front half of the fixed top plate 8 a are cutouts B, and the cutouts B constitute a part of the opening A together with the front side of the box 1. Further, on both left and right sides of the cutout portion B in the fixed top plate 8a, left and right uncut portions 17 and 18 along the upper ends of the side walls 3 and 4 are connected to the upper ends of the side walls 3 and 4 with a predetermined left and right width. At least, when the movable top plate 8b is overlapped with the fixed top plate 8a side, the left and right sides of the movable top plate 8b and the uncut portions 17 and 18 overlap to constitute the above-described regulating portion.

At the end of the cutout portion B of the fixed top plate 8a and the center of the tip of the movable top plate 8b, there are handles 9a, 9b, which overlap each other in a standing state when the top plates 8a, 8b are overlapped. Provided. Further, the tongue portions 19a and 19b are extended so as to protrude at least one of the end of the cutout portion B of the fixed top plate 8a and the front end of the movable top plate 8b, and the tongue portions 19a and 19b are moved. By engaging with the 8b side or the fixed top plate 8a side, a restriction portion is formed together with the uncut portions 17 and 18.

At the left and right base ends of the handle 9b on the movable top plate 8b side, the opening A is closed with the movable top plate 8b, and the handle 9b is set up. A restricting portion is formed by engaging the inner end of the base end portion 18 with the concave portion 21 to restrict the vertical movement of the movable top plate 8b.

Also, at the peripheral end of the rear wall 7 or a component of the rear wall 7, claw portions 22 a, 23 a, 24 a are protruded, and at least one of the side walls 3, 4 and the top plate 8 a or the bottom plate 2 Claw holes 22b, 23b, 24b into which the claw portions 22a, 23a, 24a are inserted and locked when the box body 1 is assembled by extending the rear wall 7 from the folded state at the end on the connection side with the wall 7. Is provided to maintain the rigidity of the rear wall 7 in the box assembly state.

In the illustrated example, the claw portions 22a to 24a are provided on the left end on the rear wall piece 7b side continuous with the bottom plate 2 side and on the right end and the lower end on the other rear wall piece 7a side, respectively. The claw holes 22b to 24b are provided at the rear ends of the left and right side plates 3 and 4 and the rear end of the bottom plate 2, respectively. In addition, in this example, the front ends of the uncut portions 17 and 18 are set to protrude, for example, about 1 mm forward from the front and rear lengths of the side plates 3 and 4, and the assembling (closing) operation is performed when the movable top plate 8b is inserted and assembled. The structure is easy to perform.

[0021]

[Effect of the invention]

 According to the present invention configured as described above, the rear wall is disengaged and divided so as to be assembled and foldable, and the front opening type is used. Can be easily folded and assembled. In addition, since the front surface of the box or the upper surface of the front half is open, there is an advantage that cakes can be easily taken in and out, and cakes are less damaged.

Further, the upper side of the box also has a good sealing property due to the overlapping of the fixed top plate (or the uncut portion) and the movable top plate, and the regulating portion also improves the fixability of the movable top plate to the fixed top plate. Combined with the functions of the claw portion and the claw hole provided on the rear end side, the stability of the entire box and the stability of the top plate are improved. In addition, as shown in FIG. 6 and FIG. 7, there is an advantage that stacking and planar arrangement of the boxes are easily performed.
