Description

[Detailed Description of the Invention] The present invention relates to an assembly type paper box blank for storing a plurality (4 pieces) of small, granular fruits such as cherries or strawberries packed in plastic boxes.

Generally, this type of paper box blank is assembled at the harvest site, and the packed fruits are stored one after another, and because the boxes are stacked and shipped, each paper box does not have a cover plate. Since it is recycled and delivered to the retail store, it contains disposable elements that are only used once and are difficult to reuse.

Despite this, this type of box is constructed with double or triple layers on the side and end surfaces to increase the pressure resistance when stacked, but this requires a large amount of material for the size of the box. This not only resulted in poor assembly workability but also resulted in increased costs.

The present invention was made in order to eliminate these drawbacks, and the purpose is to create an assembly-type paper box that uses fewer materials but maintains its strength, can be provided at low cost, and is easy to assemble. It is intended to provide a blank.

The present invention was developed to achieve this purpose.
Both end faces and both side faces are integrally connected to a rectangular bottom surface via a fold, and finger hook pieces are connected to each free end of the both end faces, and each end is folded inward. A wing piece is provided, and a folded side face is connected to the inner side through a folded part serving as an upper edge at the free end of the side face, and wing pieces are integrally connected to both sides of the side face, respectively. , a fan-shaped corner holding member is connected to each of these wing pieces, and an insertion piece cut out from the end of the folded side surface is connected to one side of each corner holding member,
A prefabricated paper box blank characterized in that insertion holes into which these insertion pieces are inserted are formed from the folded portion to the side surfaces, and the blank is characterized in that after both end faces are erected, the end faces are folded. Fold the folded sides inward by sandwiching the pieces inward, then fold the finger hook pieces inward, open the wing pieces outward and fold them to the gable side, and position the corner holding members at the top of each corner and insert them. A box is formed by inserting the pieces into the insertion holes. The finger rest is located on the inside of the gable, making it easier to carry, and the sides are double.
Moreover, since the folding pieces are also sandwiched, they can withstand the strength of stacking.

Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numeral 1 is a rectangular bottom made of corrugated paper, and both end faces 4 and 5 are formed on the four circumferences of the bottom through folds 2 and 3. Both side surfaces 8 and 9 are connected to each other through folds 6 and 7.

Folds 4 are formed on the free end sides of both the end faces 4 and 5, respectively.
Band-shaped finger hooks 4b and 5b are connected to each other via a and 5a, and folding pieces 14 to 17 are connected to each other by folds 10 to 13 on both sides. At the top of these folding pieces, there are protrusions 14 that fit into insertion holes, which will be described later.
a, 15a, 16a, and 17a are formed.

At the free end portions of both side surfaces 8 and 9, a folded side surface 20,
21 are installed in series. Furthermore, wing pieces 26 to 29 are formed on both sides of both sides 8 and 9 through folds 22 to 25.
fan-shaped corner holding members 30 to 33 are integrally connected to these wing pieces. Further, tongue-shaped insertion pieces 34 to 37 cut out from both ends of the folded side surfaces 20 and 21 are integrally connected to one side surface of these corner holding members.
In addition, there are insertion holes 38 to 41 into which the insertion pieces 34 to 37 are inserted to hold the box body when forming the box body.
are provided over the folded portions 18, 19 and the side surfaces 8, 9, respectively. The folded side surface 20, 2 described above
Protrusions 42a near both ends of the free end of 1,
42b, 43a, 43b are provided, and holes 44a, 44b, 45a, 45b into which these projections fit are provided along the folds 6, 7 of the bottom surface 1. Incidentally, reference numerals 46 to 49 in the figure are holes into which partition plates to be described later are attached.

What is shown in Fig. 2 A and B is a pair of partition plates 5
0.51, and the one shown in figure A is for horizontal partitioning and has a slit 5 for engagement at the center of the lower end.
2 and a pair of notches 53, 5 at the upper end.
4 is provided. This notch is designed so that a finger can fit into it when inserting or removing the package cage.
The partition plate 51 in FIG. B is for partitioning in the vertical direction, and has an engaging slit 55 at the center of the upper end, and is used by engaging with the slit 52 of the horizontal partition plate 50. do.

The assembly-type paper box blank of the present invention having the above-mentioned configuration is stored and transported in the unfolded state shown in FIG. 1, and is used by assembling the required number at the site of use. To assemble it, first, both end faces 4 and 5 are made to stand up against the bottom face 1, and each of the folding pieces 14 to 17 is bent inward to form a U-shape as a whole. Subsequently, when one side 8 is stood up and further folded back at the folding part 18 and the folded side 20 is folded inward, the protrusions 14a, 16 of the folding pieces 14, 16
a is fitted into the insertion holes 38 and 39 and stabilized, and the protrusion 42
a into the hole 44a and the protrusion 42b into the hole 44b, respectively, and the side surface 8 and the folded side surface 20 form the folding pieces 14, 1.
Hold 6. The other side surface 9 is raised in the same way, folded back at the folded part 19, folded side surface 21 is folded inward, and the protrusions 15a, 17a are inserted into the insertion holes 40, 41.
The protrusion 43a is inserted into the hole 45a, the protrusion 43b is inserted into the hole 45b, and the folding pieces 15 and 17 are held between the side surface 9 and the folded side surface 21.

Next, the inner partition plates 50 and 51 shown in FIG. Then, the finger rest becomes like a frame on the gable side.

In this state, the wing pieces 26 and 27 are folded toward the wife surfaces 4 and 5, respectively, so that the corner holding members 30 and 31 are located at the corners of the box, and the insertion pieces 34 and 35 are inserted into the insertion holes 38 and 39. Insert it. Similarly, fold the wing pieces 28 and 29 on the other side toward the end faces 4 and 5, and insert the insertion pieces 36 and 37 into the insertion holes 40 and 41, respectively.
When inserted into the box, a complete box with partitions is formed. The inside of the box is divided into four rooms by a partition, and each room stores a package cage containing fruit.

As explained above, the main part of the box construction blank is composed of both end faces, both side faces, and the folded side faces connected to the bottom face, and considering the size of the box body, Few materials are required, and the assembly work is extremely easy, as all that is required is raising the end face, raising the side face, folding back the folded side face, and inserting the insertion piece. In particular, for this type of paper box, which is disposable, the use of less material means that the price of the box can be lowered, and it is also lightweight, making it easy to carry. Due to its presence, various excellent effects can be achieved, such as preventing fingers from contacting the stored items and damaging the stored items when carrying the item, and increasing the strength of the end surface.
