Description

  The present invention relates to a non-staple case suitable for storing relatively heavy fruits and vegetables such as root vegetables.

  Conventionally, JIS-Z1507 0201 type (formerly A-1 type) boxes that have been produced in a factory and delivered in an assembled state are often used as packaging boxes used when packaging fruits and vegetables. 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 shipped with a variety of sizes and heavy fruits and vegetables, so that the case will not be distorted by the weight of the stored items, or the bottom flap will open and the product will not fall off. The overlapped portions of the flaps were shipped by joining with secondary materials for sealing such as metal fittings called tapes and stitchers.

  However, it is necessary to prepare a tape, a sealing metal fitting, and a driving machine for the box sealing work. Therefore, the cost of the secondary material for sealing is high, and there is a possibility that the stored items in the box may be damaged by driving the sealing metal fitting into the bottom surface. Also, the metal fittings after use cannot be incinerated with combustibles such as corrugated paper, and need to be separated.

  In addition, in general, in general merchandise stores, fruits and vegetables boxes are required to be safe and convenient for opening and disassembling after use. 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 it is injured by the metal needle when unpacking the box or separating it after dismantling. In some cases, special attention must be paid to handling.

  The purpose of the present invention is to make it possible to carry out the sealing and dismantling work of the box easily and with high safety without using auxiliary materials for sealing such as tape and sealing metal fittings, as well as carrots and potatoes. The present invention provides a non-staple case for fruits and vegetables that can prevent the case from being distorted and the bottom surface from opening even when a relatively heavy load of fruits and vegetables such as radishes is applied.

In order to solve the above-mentioned problem, the first device is connected to the opposite side plates (1, 3) on the length side, the opposite side plates (2, 4) on the width side, and the lower ends of these opposite side plates. The bottom plate forming flaps (5, 7, 6, 8) and the upper lid forming flaps (9, 11, 10, 12) connected to the upper ends of the opposite side plates (1, 3, 2, 4), respectively. ), The bottom plate forming flaps (5, 7) connected to the lower ends of the opposite side plates (1, 3) on the long surface side are arranged on the width surface side. The bottom plate is formed in such a manner that the ends of the opposing side plates (2, 4) are in a size that is in a state of abutting with each other at the time of assembly, and is connected to the lower end of the opposing side plate (2, 4) on the width surface side. The flaps (6, 8) are formed as a pair of short flaps so that they cannot butt each other, The short flap forms a ruled line parallel to the base continuous line, and is provided with a central convex portion and left and right convex portions at the tip of the short flap, and is provided on the opposing side plate (1, 3) on the length surface side. In the bottom plate forming flaps (5, 7) provided continuously, a notch for pressing and engaging the right and left convex portions provided at the tip of the short flap at a position where it overlaps with the short flap (6, 8) during assembly, A notch for pressing and engaging the central convex part is provided, and the central convex part and the left and right convex parts are respectively engaged with the three notches of the bottom plate forming flap (7) to be closed first, thereby closing first. A non-staple case characterized in that the bottom plate forming flaps on the length side are free from distortion and opening of the abutting line between the flaps and prevent the stored product from falling off.

The invention of claim 2 is such that the bottom plate forming flaps (5, 7) connected to the lower ends of the opposing side plates (1, 3) on the long surface side straddle at least the butt line of the tips of both flaps. The non-staple case according to the first aspect, wherein a cut extending in an orthogonal direction is formed.

The invention according to claim 3 is the non-staple case according to the first invention, characterized in that the incision for pressing and engaging the left and right convex portions is formed in a substantially U-shape or a substantially J-shape. .

  The packaging box of the present invention does not require auxiliary materials for sealing such as tape and sealing hardware for assembling the bottom plate, and even if a relatively heavy load of fruits and vegetables is applied to the bottom, the case is distorted or the bottom is opened. Can be prevented.

  Next, embodiments of the present invention will be described with reference to the drawings. This packaging box is suitable for shipping fruits and vegetables with a considerable load on the bottom of the box, but 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 has a pair of side plates 1 and 3 on the long side that constitute a long surface among the opposing side surfaces of the box, and a pair that constitutes a width surface in the central portion of the sheet. The side plates 2 and 4 on the short side are connected in one direction via a broken line, and a pair of short side plates 2 and 4 are provided with a handle hole at the center upper part thereof. Further, bottom plate forming flaps 5, 7, 6 and 8 are connected to the lower ends of these side plates 1, 3 and 2 and 4 through broken lines. Further, upper lid forming flaps 9, 11 and 10, 12 are connected to the upper portions of the side plates 1, 3 and 2, 4 via a broken line.

The bottom plate forming flaps 5, 7, 6, and 8 are formed with locks for fixing the bottom surface as follows. That is, as shown in FIG. 1, the four flaps are all formed in the same length, and the bottom plate forming flaps 5 and 7 connected to the lower ends of the opposing side plates 1 and 3 on the long side are rectangular and assembled. In some cases, the ends of the opposing side plates 2 and 4 on the short side are formed in such a size that the ends are in contact with each other (see FIG. 4 or FIG. 6).
The pair of flaps 6 and 8 on the width surface side are formed as short flaps. The short flaps 6 and 8 are provided with ruled lines b that can be folded in three parallel to the base continuous line. Further, the tip of the short flap is formed in a concavo-convex shape, and is provided with an insertion convex portion including left and right convex portions 13a and 13c and a central convex portion 13b.

  On the other hand, the other flaps 5 and 7 on the long surface side are provided with left and right convex portions 13a and 13c and cut holes 14a and 14b for pressing the central convex portion 13b. The cut holes 14a and 14b are formed at positions where they overlap with the pair of bottom plate forming flaps 6 and 8 when assembled. The cut holes 14a and 14b are formed at positions substantially orthogonal to the butt line C at the tips of the bottom plate forming flaps 6 and 8, as will be described later.

  As shown in FIG. 1, the long-side upper lid forming flap 9 has a diagonal ruled line 15 and a cutout portion 16 from one end thereof, and the adjacent flap 10 is connected to a cutout portion 17 corresponding to the cutout portion 16. A ruled line 18 parallel to the line is provided. Reference numeral 19 is an adhesive margin connected to the end of the side plate 1.

Next, how to assemble the blank will be described. First, the four side plates 1, 3, 2, and 4 are connected to each other in a rectangular tube shape through adhesive margins. Thereafter, the bottom plate forming flaps 5, 7 on the long side are closed first, and the bottom plate forming flaps 5, 7 are brought into contact with each other as shown in FIG.
Next, it is bent from the continuous lines of the short flaps 6 and 8 and the ruled line b, and the insertion convex parts composed of the left and right convex parts 13a and 13c and the central convex part 13b at the tips of the flaps are formed on the bottom plate forming flaps 5 and 7. It engages and locks by pushing into the notches 14a and 14b (see FIGS. 2 to 4).

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, 12 (see FIGS. 7 to 9)
As shown in the figure, first, the long side flap 9 is bent 90 degrees inward, and then the short side flap 12 is bent so as to be overlaid thereon. Subsequently, the flap 11 on the long side is folded so as to overlap the flap 12 on the short side, and finally the remaining flap 10 is folded along the ruled line 18 so as to overlap the flaps 9 and 11, and the flap. By inserting a cutout portion 17 provided at the other end of the flap 10 adjacent to the cutout portion 16 provided at one end of the flap 9, the flaps 9 to 12 on the top surface are engaged with each other. When sealing the top of the box in this way, it is possible to prevent the inner and outer flaps from opening, just as when the top flaps (four corners of the top) are sealed with sealing brackets. Even if the inside is full of vegetables, the sealing work can be done without damaging the inside vegetables.

  When opening the top of the box, if the leading end of the cut portion of the flap 10 is grasped and pulled upward, the flap is pulled upward while the ruled line 18 is bent, so that the cut portions 16 and 17 are pulled upward. The lock can be released and the top of the box can be easily opened.

  FIG. 5 shows a sheet (referred to as a blank) of a cardboard box showing the second embodiment. The difference between the second embodiment and the first embodiment is the shape of the cut holes provided in the bottom plate forming flaps 5, 7 and 6, 8. That is, in the first embodiment, the cut hole 14a is formed in an approximately U shape as an example. On the other hand, in this example which is a 2nd Example, it forms by cutting in a substantially J shape. In the first embodiment, three ruled lines b are provided on the short flaps 6 and 8 in parallel with the base continuous lines. However, the number of ruled lines is not limited to three. It may be a book. FIG. 6 is a bottom assembly view of the second embodiment.

  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, there is provided a non-staple case of vegetables with high sealing force that can prevent the bottom plate forming flaps 5, 7 from collapsing even if a considerable load is applied to the bottom surface, or the inner and outer flaps to fall and the box to open. It is something that can be done.
