DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling paper box with partitions which can be folded flat and stacked before use, and assembled without gluing during use, and a partition body thereof.

[0002]

2. Description of the Related Art Heretofore, there has been known an assembling type tray-shaped paper box which is stacked flat as one sheet of paper before use and assembled without using glue at the time of use. As this kind of box, for example, after being shipped from the factory, it is assembled manually, and those used at the packaging site or those shipped from the factory are stacked at the store so as not to be bulky. There is a known package that can be easily assembled and used on the spot when packaging.

[0003] In the case of a simple packaging box made of one piece of cardboard, which is often used for packaging cakes, an assembly type packaging box having a handle for hanging by hand is generally used. However, in the case of a box that is relatively sturdy and has a slightly high-grade appearance, such as a tray-shaped paper box for storing a plurality of cookies, the side wall is made of two.
It is desired to have a double structure.

[0004] As a tray-shaped box having such a double side wall structure which can be assembled at a store such as a confectionery store, a so-called Thomson box as shown in FIGS. 27 to 30 is known. I have. FIG. 27 is a development view before assembling, FIGS. 28 and 29 are views during assembling, and FIG. 30 is a view in an assembled state. In FIG. 27, the valley fold line is shown by a solid line, and the mountain fold line is shown by a broken line (the same applies to the developed views below).

A sheet cut from one sheet as shown in FIG. 27 is folded as shown in FIG. 28 to raise the front and rear double side walls 2 and 4, and left and right as shown in FIG. (Only one side wall 6 is shown), and the assembled pieces 3, 5, 7, 9 connected to the ends of the raised side walls 2, 4, 6, 8 are folded inward. And bent inward so as to pinch them. Finally, the both ends of the bent pieces 6a, 8a that are superimposed on the bottoms connected to the lower ends of the inner walls of the left and right side walls 6, 8 are joined to the inner walls of the front and rear side walls 2, 4. 3 is sunk beneath both ends of bent pieces 2a and 4a superposed on the bottom connected to the lower end of FIG.
Complete the box like 0. This makes it easy to produce a sturdy, high-quality tray-shaped paper box with a double side wall structure. That is, a box can be easily assembled from sheets stacked flat one by one before use without gluing at the time of use.

In this case, the bent pieces 6 of the left and right side walls 6, 8 are provided.
a, 8a are bent pieces 2a, 4a of front and rear side walls 2, 4.
The lower part of the inner side of the side wall which is bent inward is thereby locked with each other so that the lower end of the inner wall part of the side wall is locked together, and the side wall does not float due to the restoring force, thereby fixing the shape of the box. is there.

On the other hand, a tray-shaped paper box is divided into a plurality of sections so that the confectionery and the like can be displayed in a confectionery store or the like and arranged in a box with good appearance. There are various types of prefabricated paper boxes with a partition for accommodating one by one. In that case, the partition made of paper or plastic is used.

[0008]

By the way, the above-mentioned paper boxes are stacked flat so as not to be bulky before use, and have an effect of being assembled without using glue at the time of use. When assembling a box from the cut out paper, bend the paper correctly along the folding line, and let the both ends (four places) of the bent pieces on the left and right side walls go under the both ends of the bent pieces on the front and rear side walls It's not easy but messy. Therefore, when assembling the box at a store or the like, the customer has to wait for a long time, which is not preferable for business. If assembled in advance, the customer will not wait, but that would be bulky and take up space, which is undesirable.

[0009] Therefore, it is desired to omit the locking operation of lowering both ends of the bent piece downward. In order to prevent the lower end of the inner wall portion of the side wall bent inward from floating due to the restoring force of the side wall. Requires some ingenuity. For example, a method of putting a bottom plate (bottom pad) to suppress the floating of the side wall is conceivable, but since the bottom plate is separate from the box main body, when stacked and stored before use, the bottom plate separates from the main body and falls apart. There is a risk. Also, since the side wall is almost free until the bottom plate is fitted, the shape of the assembled box cannot be maintained until the bottom plate is set,
It is very difficult to assemble and cannot be assembled successfully in reality.

[0010] In order to cope with such a problem, in order to simplify the on-site assembly, a temporary assembly in a form easy to assemble beforehand is folded and then assembled on the site with one touch. It has been proposed ("Push Box" by Toko Co., Ltd.). this is,
After assembling, only the center of the lower end of the side wall that is going to approach each other by the restoring force of the side wall is glued to the bottom surface, and both ends of the lower end can be folded back diagonally so that the adjacent side wall can be sandwiched during assembly. Before use, the side walls are folded inward before use so that they can be stacked flat without bulk.

However, this one-touch assembling type box is not always easy to glue only the central portion of the lower end of the side wall to the bottom surface before use at the site, and there is a problem in cost. In addition, since the lower end portion other than the central portion where the side walls are glued is floated after assembling along the fold, there is a problem that a separately prepared bottom plate must be inserted and pressed, and the assembling work on site is actually required. Is not a true one touch but two actions. Further, since the bottom plate is used, the bottom plate is separate from the box main body as in the above-described example. Therefore, when the bottom plate is stored before being used, the bottom plate may be separated from the main body and fall apart.

Further, when a partition is provided on a prefabricated paper box such as a Thomson box, it is common to insert the partition into the floor of the paper box after assembling the box main body. When storing, the partitions must be stored separately, and in the case of paper partitions, the paper must be folded and fitted into the box main body when assembling the box main body. Further, in the case of a partition made of plastic, there is a problem of environmental pollution after disposal, and furthermore, there is a drawback that the cost for making a mold is increased.

In view of such problems, a first object of the present invention is to extremely easily assemble with one-touch operation, and when storing the partitions in a stack before use, the partitions are not separated from the main body and lost. An object of the present invention is to provide a partitionable paper box with a partition.

A second object of the present invention is to provide a partition member suitable for use in the above-described partitionable paper box with a partition.

[0015]

SUMMARY OF THE INVENTION A prefabricated paper box with a partition according to the present invention is a prefabricated paper box with a partition which is folded and stacked before use and assembled without gluing at the time of use. It consists of a tray-shaped box main body with a double-structured side wall rising on the four sides of the bottom, and a partition inserted into the bottom of the box main body.
A bottom plate provided on both side edges with locking portions that can be locked to the lower ends of the inner wall portions of the pair of opposed side walls of the box main body, and fall down on this bottom plate before use, and stand up on the bottom plate during use. And a partition provided on the bottom plate.

Here, the "lower end" of the inner wall portion of the side wall includes not only the lower edge of the inner wall portion of the side wall but also a bent piece which is connected to the lower end and is bent along the bottom surface. Further, the locking portion can be constituted by a combination of a cut and a protruding piece fitted and locked in the cut.

Prior to use, the partition body is a box in a state where the partition is laid down on the bottom plate, and the locking portion of the bottom plate is locked to a folded box body. It is desirable that the box body is overlapped on the main body, and is configured to allow assembly of the box body and start-up of the partition while the locking portion of the bottom plate is locked to the box body during use.

Further, the partition has a bi-folded partition wall that extends linearly in a first direction that rises on the bottom plate so as to be able to fall down by partially turning the bottom plate, and a second folding wall that is substantially perpendicular to the first direction. And a strip-shaped partition piece that is inserted into and locked from the partition wall from the direction of (i).

The direction of the first direction is generally a direction parallel to a pair of opposed side walls of the box body, and the second direction is a direction parallel to the other pair of opposed side walls of the box body. is there.

Further, the band-shaped partition piece is laid down on the bottom plate when the partition wall is laid down on the bottom plate, and rises with the rising of the partition wall to form a partition together with the partition wall. Is desirable.

Next, the partition body according to the present invention is provided on the bottom plate inserted into the bottom of the tray-shaped box main body and on the bottom plate so as to lie down on the bottom plate before use and stand on the bottom plate during use. A partition wall which rises so as to fall down on the bottom plate in a folded state by partially folding the paper forming the bottom plate and extends linearly in the first direction; And a band-shaped partitioning piece that is inserted into and locked by the partition wall from a second direction substantially at right angles to the bottom plate, and the band-shaped partitioning piece is placed on the bottom plate when the partition wall is lying down on the bottom plate. The partition wall rises with the rising of the partition wall to form a partition together with the partition wall.

In this partition body, at least four flat and relatively large confectioneries (for example, moon cakes) are displayed.
A first embodiment having an inclined article mounting surface, and a second embodiment in which a booth for accommodating at least four confectioneries (for example, nut-containing chocolate) having a relatively small and nearly cubic shape is formed. There is.

In a first aspect of the partition body according to the present invention, the strip-shaped partition piece is bent with a mountain fold line extending in the longitudinal direction as an upper edge, and a wide article mounting portion which forms an inclined surface when used. And a narrow leg hanging down from the upper edge of the article mounting portion.

The article mounting portion has a first slit extending from an upper edge of the article mounting portion halfway in the width direction of the article mounting portion, and a partition wall of a band-shaped partition piece extending from a lower end of the first slit. And a notch extending in the direction opposite to the insertion direction with respect to

On the other hand, the partition wall has a second slit extending vertically upward from the lower end of the partition wall to the middle of the partition wall, and the leg portion is aligned when the partition wall and the band-shaped partition piece rise. Engagement which is inserted into the first slit of the band-shaped partition piece when the partition lays down and presses the back surface of the leg of the band-shaped partition piece as the partition wall rises to align this leg with the second slit. A piece and an inclined edge portion that contacts the upper surface of the lower portion of the article placement portion from above are connected to each other.

In a second aspect of the partition body according to the present invention, the strip-shaped partition piece is folded in two along the mountain fold line with the mountain fold line extending in the longitudinal direction as the upper edge, and A third slit is formed from the edge to extend halfway in the width direction of the strip.

A fourth slit is formed in the partition wall. The fourth slit includes a first groove portion extending vertically upward from the lower end of the partition wall to a halfway position, and a first groove portion. Second and third grooves extending from the upper and lower ends in a direction perpendicular to the first groove and in directions opposite to each other.

In the band-shaped partition piece, the bottom of the third slit is engaged with the tip of the second groove of the fourth slit of the partition wall and the skirt portion is connected to the fourth groove in the folded state of the partition. The slit is inserted through the partition wall in a state of being inserted into the third groove of the slit.

[0029]

The prefabricated paper box with a partition according to the present invention is
Since the partition body has a bottom plate provided with locking portions on both side edges that can be locked to the lower end of the inner wall portion of the opposed double side wall of the box main body, when the box main body is assembled, It is possible to prevent the lower ends of the inner wall portions of the rising side walls from floating and approaching each other.

Further, the inner walls of the pair of opposed side walls of the box body in the folded state can be connected to each other by the bottom plate of the partition body. Hold down trying to get up with resilience,
In addition to being able to maintain a flat shape, before use, the partition body with the partition laid down on the bottom plate and the box body can each be stacked in a flat shape,
Even if they are stacked, they are not bulky, and the partition body does not separate from the box body.

Furthermore, when used, there is an advantage that the assembly of the box body and the start-up of the partition can be assembled with a single touch while the engaging portion of the bottom plate of the partition body is kept engaged with the box body.

Further, in the partition body according to the present invention, the strip-shaped partition piece is laid down on the bottom plate when the partition wall of the partition is laid down on the bottom plate, and with the rise of the partition wall. Since it is configured to stand up and form a partition with the partition wall, there is an advantage that the formation of the partition is extremely easy.Moreover, the partition body is made of paper together with the box body and is recyclable, and is made of plastic. As in the case of the partition described above, the problem of environmental pollution after disposal and the drawback of increasing the cost for mold preparation can be overcome.

In a first aspect of the partition body according to the present invention, a first slit extending from an upper edge of the strip-shaped partition piece to a middle part in a width direction of the strip is provided. A notch extending from the lower end of the first slit in a direction opposite to a direction in which the strip-shaped partition piece is inserted into the partition wall is formed, and the partition wall is engaged with the first slit of the strip-shaped partition piece when lying down. Since the pieces are suspended, the partition wall portion at the root of the engaging piece is moved in the region between the first slit and the notch of the article mounting portion with the rise of the partition wall. Since the edge of the first slit is pushed while being bent upward, the article placing portion is pulled up while the strip-shaped partition piece moves in the longitudinal direction.

Further, the engaging piece presses the back surface of the leg of the strip-shaped partitioning piece with the rising of the partitioning wall and aligns this leg with the second vertical slit. With the lifting, the leg of the strip-shaped partition can also rise vertically. Further, the partition wall is provided with an inclined edge which comes into contact with the upper surface of the lower part of the article placement part of the strip-shaped partition piece from above, so that the article placement part is maintained in a predetermined inclined state in a rising state. be able to.

Further, in the second aspect of the partition body according to the present invention, the partition wall has a region interposed between the first groove portion and the second groove portion of the fourth slit orthogonal to each other, and a region orthogonal to the region. A region sandwiched between the first groove portion and the third groove portion is formed vertically on both sides of the first groove portion, and
In the folded state of the partition, since the bottom of the third slit of the strip-shaped partition is engaged with the tip of the second groove, when the partition is raised, the upper region is bent and the middle of the strip-shaped partition is bent. Press the part obliquely upward from below,
By pressing the lower part of the band-shaped partition piece obliquely downward while the lower region is bent, a rotational force is applied to the band-shaped partition piece in the rising direction, and the bottom of the third slit of the band-shaped partition piece has the second slit. The band-shaped partition piece rises while sliding along the upper edge of the groove toward the first groove, and the band-shaped partition piece engages the bottom of the third slit with the upper end of the first groove to form the first groove. Is matched to

Even when a plurality of partition walls and strip-shaped partition pieces are provided, all the partition walls and strip-shaped partition pieces are in a state in which the slits are engaged with each other in the falling state of the partition. Therefore, with the rise of any one of the partition walls, a plurality of strip-shaped partition pieces engaged with the partition wall rise at the same time, and thereby the remaining one or more partition walls also rise and partition. Has a great advantage of being completed.
