Description

[Detailed description of the invention] The present invention relates to a multi-layered box type tray. Conventionally, trays based on paper cartons had weak edges and four corners due to the material, and there was no tray strong enough to be used as a substitute for a multi-layered box. For this purpose, we have developed a multi-box tray that eliminates the defects of the conventional tray, has strong sides and corners, has legs, and can be stacked.

The structure of the present invention will be explained with reference to one embodiment according to the above-mentioned purpose.
2A' are provided, inner flaps 8, 8', 9, 9' are connected to the outwardly sloping side edges of the inner side plates 2, 2', and fold creases are provided. 13,1
Crease line 1 on the side edge of inner side plate 2, 2' opposite to 3'
The outer side plates 4, 4' are provided through the outer side plates 4, 14', and the outer side plates 4, 4' are formed with creases 14, 14' on both side edges of the outer side plates 4, 4' that are inclined inward. Inner side version 2,
When folding 2', the inner flaps 8, 8', 9,
outer flaps 10, 10', sized to cover 9';
11, 11' are arranged in series, and a cutout hole 1 is provided in the center of the side edge of the outer side plates 4, 4' facing the creases 14, 14'.
2, 12' are formed through the folding lines 15, 15', and the bent pieces 6, which have the glue placement parts 6A, 6A' are inserted.
6' on the other opposing sides of the bottom plate 1,
Inner side plates 3, 3' having both side edges inclined outward are provided through the creases 16, 16', and the creases 16, 1
Outer side plates 5, 5' whose both side edges are inclined inward are connected via creases 17, 17' on the side edges of the inner side plates 3, 3' facing opposite to 6'. 17,1
7', the folded pieces 7, 7' each having a corrugated tip and having glue placement portions 7A, 7A' are inserted through the creases 18, 18' on the side edges of the outer side plates 5, 5' opposite to 7'. The bent pieces 6, which are arranged in series to form a blank body,
6' is valley-folded inward at creases 15, 15', and the glue placement parts 6A, 6 are placed on the outer side plates 4, 4'.
Glue at A', then valley fold at creases 14, 14', fold outer side plates 4, 4' onto inner side plates 2, 2', glue at glue placement parts 2A, 2A', and fold. The pieces 7, 7' are valley-folded inward at the creases 18, 18', folded and glued onto the outer surface plates 5, 5' at the glue placement parts 7A, 7A', and the creases 13, 13', 16,
At 16', raise the inner side plates 2, 2', 3, 3',
Flaps 8, 8', 9, folded in two,
9', 10, 10', 11, 11' are bent inward, respectively, and the inner side plates 3, 3' and the outer side plates 5, 5' are folded together via the creases 17, 17'. The structure is a multi-box type tray that is made by holding the paper in a box.

The present invention is constructed as described above, and the assembly, operation, and effects thereof will be explained in detail according to the drawings.
At this point, the folded pieces 6, 6' are valley-folded inward at the creases 15, 15' using the glue placement parts 6A, 6A', and then glued onto the folded outer surface plates 4, 4'.
The central notched holes 12, 12' are folded in half to form legs (see FIG. 2).

Furthermore, the creases 14, 14' are valley-folded to form the outer surface version 4,
Fold 4' onto the inner side plates 2 and 2' and glue the adhesive part 2.
Glue A, 2A' (see Figure 3).

Next, the bent piece 7 facing the other side of the bottom plate 1,
7' is valley-folded inward at creases 18, 18', and folded and glued onto the outer surface plates 5, 5' using glue placement parts 7A, 7A' (see FIG. 4).

The paper plate glued in the first step using the gluing machine as described above is further formed into an inner side plate 2,
2', 3, 3' are raised, and the flaps 8, 8', 9, 9', 10, 10', 11,
11' and glued in the glue placement parts 5A and 5A' to form a box (see Fig. 6).

Normally, in the first step, the folded pieces 6, 6' are formed by a gluing machine at the creases 15, 15' and the outer side plates 4, 4'
Fold it over and glue it, then make creases 14, 1.
Fold it over the inner side plates 2 and 2' at 4' and glue it,
Next, the other opposing bent pieces 7 and 7' of the bottom plate 1 are folded and glued along the creases 18 and 18', and a large amount of semi-finished products (see Fig. 5) are stacked and stored in advance. Inner flaps 8, 8', 9, 9' and outer flaps 10, 10' are folded into two pieces in a second process using a box-making machine, after being glued in the first step as necessary. , 11, 11' into the other inner side plates 3, 3' and outer side plates 5, 5',
A multi-box type tray is manufactured by applying glue at the glue placing portions 5A and 5A'.

Since the present invention has a double or triple structure on all four sides, even a weak paper carton can be made into a strong multi-box tray, and the four corners have an angular configuration designed to make it suitable for gluing box manufacturing.

By providing the inner flaps 8, 8', 9, and 9', when molded, the appearance is beautiful with no gaps at all, and the contents do not leak.

Furthermore, if a material paper with a film that does not allow moisture to permeate is attached to the entire surface, there is no risk of the paper losing its shape even if an object containing moisture is directly stored therein.

The edges of each of the inner and outer plates constituting the tray are diagonally arranged to form an angle that widens upward so that the boxes can be stacked after being made. ’ bent piece 1
5 and 15' are the legs, giving the appearance of a jubako box, and the raised bottom of the box body makes it sit comfortably and stably.

Further, since the bent pieces 7, 7' are punched into a wave shape, it is extremely effective for bonding using a hot melt adhesive.

As described above, this is an extremely practical invention of a heavy box-type tray that has been successfully mass-produced using a gluing machine and a box-making machine.
