Description

  The present invention relates to a cardboard packaging box such as cardboard suitable for storing relatively heavy items such as root vegetables or fruits.

  Conventionally, when packaging fruits and vegetables, JIS-Z1507 0201 type (formerly A-1 type) boxes manufactured and delivered in an assembled state are often used as packaging boxes. This 0201 type box has a rectangular parallelepiped shape in which rectangular four-side plates are connected in one direction, and the bottom and top surfaces of the box are sealed above and below the four-side plates. Box. This box is not fully sized or is filled with heavy fruits and vegetables, so it can be easily closed and locked with internal and external flaps when storing goods. The bottom of the flap does not drop or the bottom does not open so that it is difficult to come off, and the overlapped portion of the flap is joined with a secondary material for sealing such as a metal fitting or tape called a stitcher.

  However, the above-mentioned assembly work requires the preparation of a sealing metal fitting and its driving machine, so it is necessary to assemble at the factory, and in addition to the cost of secondary materials for sealing such as a sealing metal fitting and tape, a sealing metal fitting is attached to the bottom. There is a risk that the stored items in the box may be damaged by driving. Also, the metal fittings after use cannot be incinerated with combustibles such as corrugated paper, and need to be separated.

  In general, a box of fruits and vegetables is required to be safe and simple in unpacking operations and dismantling operations after use at the time of display in mass merchandising stores. Moreover, the generation of trash from secondary materials for sealing is avoided at mass merchandisers. Furthermore, even when a used box is reused as waste paper, it takes time and effort to separate the metal from the piece of paper as an impurity, and injuries are caused by a metal needle when unpacking the box and during sorting after unpacking. There is a problem that special care must be taken in handling.

  The purpose of the present invention is to eliminate the use of secondary materials for sealing, such as sealing metal fittings and tapes, to solve workability during box assembly, separation workability during disposal, and environmental problems, and at the same time, a considerable load is applied to the bottom surface. It is intended to provide a vegetable storage box having a high sealing power, which is provided with a composite lock that can prevent the inner and outer flaps from falling and the box from being opened even if it is applied.

In order to solve the above problems, the present invention

Thus, it is characterized in that the front end portion (5a) of the flap and the front end of the bottom plate forming flap (7) are in contact with each other under the bottom plate forming flaps (6, 8).

  In the present invention, the stopper plate (15b, 15b) is provided on the outside of the substantially L-shaped or inverted L-shaped insertion hole (15a, 15a) of the bottom plate forming flap (7) via the ruled line (15c). ). Furthermore, in the present invention, the bottom plate forming flaps (6, 8) are formed so as to be bendable from the ruled lines (13, 13) parallel to the continuous lines and from the front ends of the flaps (6, 8). Ruled lines (17c, 17c) are formed in the provided insertion holes (17a, 17b) so that the gap between the cuts extends toward the tips of the flaps 6, 8 on the short side, and is prevented from coming off via the ruled lines. It is characterized by providing a piece (17d).

The packaging box of the present invention does not require an adhesive or a fixing part for sealing metal fitting for assembling the bottom plate, and cuts into the insertion holes (15a, 15a) of the flaps for forming the long side bottom plate closed earlier ( 16a and 16b) are pressed and locked so that the locking claw portions (14a and 14b) overlap with the previously closed short side flaps, and the short side plate is formed. The tip end (5a) of the trapezoidal flap is pushed into the insertion holes (17b, 17b) provided in the flap for use, and the tip end (5a) of the flap and the bottom plate under the bottom plate forming flap (6, 8) The bottom plate can be assembled by an extremely simple operation in which the front end of the forming flap (7) is abutted.
In addition, on the outside of each of the insertion holes (15a, 15a) having a substantially L shape or an inverted L shape of the bottom plate forming flap (7), a retaining piece (15b, 15b) is continuously provided via a ruled line, Further, the bottom plate forming flaps (6, 8) are formed so as to be bendable from the ruled lines (13, 13) parallel to the continuous lines, and the notches (17a, A ruled line (17c, 17c) is formed on the outside of 17a) so that the gap between the cuts extends toward the tips of the short side flaps 6, 8, and a stopper piece (17d) is provided via the ruled line. Therefore, the bottom plate forming flap (7) is difficult to be removed from the insertion holes (15a, 15a), and the bottom plate forming flaps (6, 8) are difficult to be removed from the insertion holes (17a, 17b).

  Next, an embodiment of the present invention will be described with reference to the drawings. This packaging box is suitable for shipping fruits and vegetables such as carrots, radishes, cabbages, and the like that have a considerable load on the bottom of the box. However, the box of the present invention is not limited to fruits and vegetables.

  FIG. 1 shows a sheet (referred to as a blank) of a cardboard box showing a first embodiment of the present invention. As an example, this blank is formed from a single rectangular cardboard sheet.

  The box shown in the present embodiment includes a pair of long side plates 1 and 3 constituting a long surface (longitudinal surface) among the opposing side surfaces of the box at the central portion of the sheet, and a short surface (width surface). A pair of side plates 2 and 4 on the short side side constituting the same are connected in one direction via a broken line. The pair of short side plates 2 and 4 is provided with a handle hole at the upper center portion thereof. Then, bottom plate forming flaps 5, 7, 6 and 8 are connected to the lower portions of the side plates 1, 3, 2 and 4 via folding lines. Further, upper lid forming flaps 9, 11 and 10, 12 are connected to the upper portions of the pair of side plates 1, 3, 2 and 4 via folding lines.

  The bottom plate forming flaps 5, 7, 6, and 8 are formed with a bottom complex lock mechanism having the following configuration that does not drop and open even when a considerable load is applied when sealing the bottom surface. That is, the bottom plate forming flaps 5 and 7 connected to the lower ends of the opposing plates 1 and 3 on the long side are in contact with each other at the center in the width direction of the opposing plates 2 and 4 on the short side. The tip of one flap 5 is formed in a substantially trapezoidal trapezoidal shape 5a. The other flap 7 has a rectangular shape, but is provided with a pair of insertion holes 15a, 15a that are substantially L-shaped or reverse L-shaped and face each other in the center.

On the other hand, the bottom plate forming flaps 6 and 8 connected to the lower ends of the opposing side plates 2 and 4 on the short side are provided with a pair of cuts 16a and 16b on one side of the flap with the tip corners of the flaps sandwiched therebetween. Thus, the locking claw portions 14a and 14b having a substantially triangular shape are provided. Moreover, it has the structure which provided the notches 17a and 17b in the front end side approximate center position of the flap. A configuration in which ruled lines 17c and 17c are formed on the outer sides of the cuts 17a and 17b so that a space between the cuts spreads toward the tips of the flaps 6 and 8 on the short side, and a stopper piece 17d is provided via the ruled lines. It has become.
Reference numerals 19 and 19a are an adhesive margin connected to the end of the side plate 1 and an adhesive margin provided at the end.

Next, the method of assembling the blank will be described. First, the four side plates 1, 3, 2, and 4 are connected in a rectangular tube shape through the adhesive margins 19 and 19a (FIG. 2). After that, the notches 16a, 16a are pushed into the insertion holes 15a, 15a of the bottom plate forming flap 7 which is closed first so that the cuts 16a, 16a are engaged with each other. The triangular locking claws 14a and 14b are engaged with each other so as to overlap each other and locked as shown in FIGS. 3 and 4 (primary lock).
Subsequently, the bottom plate forming flaps 6 and 8 are pushed inward as shown in FIG. 5, and then the tip 5a of the trapezoidal flap is pushed into the notches 17a and 17b provided in the flaps 6 and 8 as shown in FIG. The front end 5a of the flap and the front end of the bottom plate forming flap 7 are brought into contact with each other under the bottom plate forming flaps 6 and 8 (secondary lock).

  After assembling the bottom surface in this way, the upper lid forming flaps 9, 11 and 10, 12 are spread to accommodate the fruits and vegetables in the box. When sealing the top surface with the flaps 9, 11, 10, and 12, as shown in FIGS. 7 to 9, first, the long side flap 9 is bent 90 degrees inward, and then the short side flap 12 is folded. Bend it so that it overlaps. Subsequently, the long side flap 11 is bent so as to overlap the short side flap 12, and finally the remaining flap 10 is bent from the ruled line 20 parallel to the continuous line. The flap 9 on the long side has an oblique ruled line 21 and a cut portion 22 from one end thereof. On the other hand, the flap 10 has a cut portion 23 corresponding to the cut portion 22. At the time of sealing, the ruled line 20 is folded so as to be superimposed on the flaps 9 and 11, and the cut portion 22 provided at one end of the flap 9 is cut into the cut portion 23 provided at the other end of the flap 10 adjacent thereto. The flaps 9 to 12 on the top surface are engaged with each other and sealed. When sealing the top surface of the box in this way, it acts to prevent the opening of the inner and outer flaps in the same manner as when the overlapping portions (four corners of the top surface) of the top surface flaps are sealed with sealing metal fittings. . Not only that, even if the inside is full of vegetables, sealing can be done without damaging the inside vegetables.

  When opening the top of the box, if the upper end of the excision part of the flap 10 is gripped and pulled upward, the flap 20 is folded upward with the ruled line 20 as a fold line, and therefore the excision part 22 The lock of 23 is released, and the top surface of the box can be easily opened.

  As described in detail above, according to the configuration of the box of the present invention, the use of sealing materials such as sealing metal fittings and tapes is abolished, and workability at the time of box assembly and separation workability at disposal and environmental problems are solved. At the same time, it is possible to provide a vegetable storage box with a high sealing force provided with a composite lock that can prevent the inner and outer flaps from falling and the box from being opened even when a considerable load is applied to the bottom surface.
