Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blank for a prefabricated paper box used for storing a plurality of fruits and vegetables such as strawberries, cherries, and radish radish packed in a plastic container.

[0002]

[Prior art]

 Generally, this kind of paper box blank is assembled at the harvesting site, and the packed fruits and vegetables are sequentially stored from the upper opening. Since the carton boxes are stacked and shipped, the side walls have a double or triple structure to increase the pressure resistance of the stack.

[0003]

[Problems to be solved by the device]

 Since the paper box assembled from the blank as described above is distributed in the market and arrives at the retail store, it contains a disposable element that is difficult to be reused after a single use. Nevertheless, the above-mentioned conventional paper box blank uses many materials (corrugated cardboard) to reinforce the side surface, and therefore, not only the workability of the assembly is bad but also the cost is increased. .

The present invention has been made in order to eliminate such drawbacks, and its purpose is to reduce the amount of materials used, to prevent deterioration in strength, and to assemble the assembly type easily. To provide blanks for paper boxes.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a blank for a collapsible paper box according to the present invention comprises a rectangular bottom panel, both side panels and both gable side panels connected to each other through a fold line, and the both side panels are on both sides. An inward folding panel is provided at each end, and each of the gabled panels is provided with a bent upper surface panel at its free end, and further, wing pieces are integrally connected at both ends of each bent upper surface panel. In addition, the winglets are formed with the insertion portions by cutting, and the insertion holes into which the insertion portions are inserted are formed in the side panels, respectively.

[0006]

[Action]

 The above-mentioned blank for a paper box according to the present invention is constructed such that both side panels are erected with respect to the bottom panel, each folding panel is bent at a right angle toward the inside, and then both gable side panels are erected, and each folding top surface is folded. A paper box is formed by bending the panel horizontally toward the inside and then bending each wing piece so that the insertion part of each wing piece is inserted into the insertion hole of the side panel.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing an embodiment of a blank for an assembling type paper box according to the present invention. The blank B is formed by punching a corrugated cardboard into the shape shown in the figure. In the figure, reference numeral 1 is a rectangular bottom panel, and side panels 4, 5 are continuously provided on four sides of the bottom panel 1 via folding lines 2, 3, and the end face panel 8, via folding lines 6, 7. 9 are installed in a row.

Inward folding panels 14 to 17 are provided at both ends of the side panels 4 and 5 through folding lines 10 to 13, and folding lines 18 are provided at free ends of the end faces 8 and 9. Bent upper panels 20 and 21 are connected to each other via a line 19 and 19, respectively.

Further, wing pieces 26 to 29 are continuously provided on both side ends of each of the bent upper surface panels 20 and 21 via folding lines 22 to 25, and these wing pieces 26 to 29 have U-shaped cuts. The insertion portions 34 to 37 are defined by 30 to 33. Then, in order to make it easy to raise the respective insertion portions 34 to 37, fold lines 38 to 41 are formed in parallel with the fold lines 22 to 25 from the tips of the respective cuts 30 to 33 toward both sides of the wing pieces 26 to 29. ing. Further, insertion holes 42 to 45 for inserting the insertion portions 34 to 37 to maintain the shape of the paper box when the paper box is constructed are provided near the both side ends of the side panels 4 and 5, respectively. A pair of notches 46 to 49 are provided from both sides of the insertion holes 42 to 45 toward the free ends of the side panels 4 and 5 in order to easily insert and fix the respective insertion portions 34 to 37. It is provided.

The blank B having the above-mentioned configuration is supplied in the unfolded shape shown in FIG. 1 and is assembled and used in the required number at the harvesting site. The assembling procedure is as follows.

First, the side panels 4 and 5 are erected with respect to the bottom panel 1, and the folding panels 14 to 17 are bent inward at right angles to obtain the state shown in FIG. Subsequently, the gabled side panels 8 and 9 are erected from the state shown in FIG. 2, and the bent upper surface panels 20 and 21 are horizontally bent toward the inside, and then the wing pieces 26 to 29 are bent to the fold lines 38 to 29. By bending at the portion 41, the insertion portions 34 to 37 are projected inward, and the protruding insertion portions 34 to 37 are inserted into the insertion holes 42 to 45 of the side panels 4 and 5 so that each blade By folding the pieces 26 to 29, the paper box shown in FIG. 1 is formed. In this case, since the insertion portions 34 to 37 have a tendency to return at the fold lines 38 to 41, the portion sandwiched by the notches 46 to 49 is slightly pulled out to the outside by the insertion portions 34 to 37, and the insertion portion 34 is also pulled out. ~ 37 is diagonally facing upward and meshes, so it will not come off.

Further, after the paper box is used, the insertion portions 34 to 37 can be easily inserted from the insertion holes 42 to 45 by lifting the outer portion of the wing pieces 26 to 29 from the folding lines 38 to 41. Since it comes off, the disassembling operation can be easily performed.

[0014]

[Effect of device]

 As described above, the blank for a prefabricated paper box of the present invention is mainly composed of both side panels and both gabled panels connected to the bottom panel, and the folding panel and the folded upper panel connected to these. Since the paper box is small, the cost is low because less material is used for the size of the paper box.At the time of assembly, the side panel and folding panel are bent and the end panel is raised. Since it is only necessary to fold the top panel and insert the insertion part of the winglet, the assembly work can be performed easily.

In addition, in this type of paper box that is in a disposable state, since it does not have a sticking part, it can be disassembled into the original blank, and therefore there is an advantage that it can be returned and reused.
