Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an edged carton.

(Prior art) Conventionally, the opening of a paper box, which is assembled by folding a single blank board, is closed by attaching an insert piece to the lid plate, bending the insert piece, and inserting it inside the box. has been done.

(Problem to be solved by the invention) However, with conventional paper boxes, if the entire paper box is slightly tilted during transportation, etc., it may open due to the weight pressure of the stored items, etc., and attempts have been made to prevent such openings. The drawback is that the opening is tightly closed and cannot be opened easily.
The object of the present invention is to eliminate such drawbacks of conventional paper boxes, and to provide a paper box that does not accidentally open during transportation and can be opened extremely easily with a single touch.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a method for connecting the rear plate 1, the side plate 2, the front plate 3, the side plate 4, and the adhesive piece through vertical fold lines a, b, c, and d. Edge pieces 6, 7, 8, and adhesive piece 9 are attached to the upper ends of the rear plate 1, side plates 2, 4, and adhesive piece 5 through horizontal fold lines e.
means that the edge piece 8 and the adhesive piece 9 are adjacent to each other via the vertical fold line g that is an extension of the vertical fold line d, and the edge piece 6 and the adhesive piece A cover plate 10 is attached to each upper end of the piece 9 via transverse fold lines h and k,
Adhesive pieces 11 are arranged in series, and cut pieces 12 and 13 having equiangular fold lines m and n are arranged in series between the cover plate 10 and the edge piece 7 and between the adhesive piece 11 and the edge piece 8, respectively, via the fold lines. An insertion piece 14 is connected to the upper end of the cover plate 10 via a fold line q having a U-shaped cut line p, and the front plate 3
A notch 15 is bored approximately in the center of the upper end, and a blank plate having a bottom is bent at right angles in order along vertical folding lines a, b, c, d and their extended vertical folding lines to form adhesive pieces 5, 9, and 11. Adhere them to the rear plate 1, edge pieces 6, and cover plate 10, respectively, and bend them along the fold lines to form the edge pieces 6, 7, 8, and adhesive piece 9, respectively, on the rear plate 1, side plates 2, 4, and adhesive piece 5. overlap the inner surface of the insert piece 1
4 is bent downward and overlapped with the inner surface of the front plate 3, the tip of the gripping piece 16 surrounded by the cut line p is exposed above the notch 15, and the bottom part is closed to provide an edged carton. do.

(Example) An example of the present invention will be explained with reference to figures.
The figure is a developed view, and the rear plate 1, side plate 2, front plate 3, side plate 4, and adhesive piece 5 are connected through vertical fold lines a, b, c, and d.
are arranged in sequence in order, and edge pieces 6, 7, 8,
The adhesive piece 9 is adjacent to the edge pieces 6 and 7 via a vertical fold line f extending from the vertical fold line a, and the edge piece 8 and the adhesive piece 9 are adjacent to each other via a vertical fold line g extending from the vertical fold line d. A cover plate 10 and an adhesive piece 11 are successively provided at the upper ends of the edge piece 6 and the adhesive piece 9 via transverse fold lines h and k,
Folding pieces 12 and 13 having equiangular folding lines m and n are arranged in series between the cover plate 10 and the edge pieces 7 and between the adhesive piece 11 and the edge piece 8, respectively, and a U-shape is formed at the upper end of the cover plate 10. The insertion piece 14 is connected through a broken line q having a cut line p, and a notch 1 is formed approximately in the center of the upper end of the front plate 3.
5, and the lower part of the box is vertically symmetrical to the upper part. In addition, r, s are notch holes, t
are auxiliary fold lines that are used to facilitate assembly during assembly, and do not need to be provided.

When assembling, as shown in FIG. 2, the adhesive pieces 5, 9, and 11 are attached to the rear plate 1 by sequentially bending them at right angles along the vertical fold lines a, b, c, and d and their extended vertical fold lines. , the edge pieces 6, and the cover plate 10 are pasted to make the whole cylindrical, and then bent along the fold lines to form the edge pieces 6, 7, 8, and the adhesive piece 9, respectively, on the rear plate 1,
Lay it on the inner surfaces of the side plates 2, 4 and the adhesive piece 5, bend the insertion piece 14 downward and overlap it on the inner surface of the front plate 3, and cut out the tip of the gripping piece 16 surrounded by the cut line p at the notch 15. The assembly is completed as shown in FIG. At this time, the folding pieces 12 and 13 are folded in half along the equiangular folding lines m and n and are brought into close contact with the lower surface of the cover plate 10. Also, edge pieces 6, 7, 8, folded pieces 12,
13. Difficulty in folding the adhesive pieces 9, 11, etc. due to their bulk is alleviated, and these can be folded smoothly.

In use, the opening can be opened with one touch by simply pulling the gripping piece 16, and the opening can be reclosed by bending the opening along the fold line and inserting the insertion piece 14.

(Effects of the invention) Since the present invention has the above-mentioned configuration, there is no risk of the product opening in a crooked manner due to the weight of the stored items even if it is tilted during transportation. It has the remarkable effect that it can be opened with one touch, is extremely easy to open and close again, and can be used repeatedly.
