Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper box used for storing a home delivery pizza.
[0002]
[Prior art]
In recent years, services for delivering cooked pizzas directly to homes in a short time have become popular. As a box for storing pizza during this delivery, a paper box is generally used in which a peripheral wall is fixed around a polygonal bottom wall and a lid is connected to the rear end.
[0003]
[Problems to be solved by the invention]
However, the paper box as described above has a problem that it is difficult to take out the pizza from the tray and is bulky when discarded.
[0004]
Accordingly, the present invention is intended to provide a paper box in which the contents can be easily taken out and can be discarded with a low bulk.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, a paper box according to the present invention connects a lid plate to a rear end edge of a bottom plate via a back plate, and provides a score line on at least one ridge portion of the back plate, the bottom plate, and the lid plate, Stand up the side plate that is connected to both side edges, fold the folded piece that extends from the side edge inward, and hold the tray with the folded piece that extends from the front edge of the bottom plate. It was formed and the back plate was erected to close the lid plate.
[0006]
In this paper box, when the cover plate is opened and the rear folding piece is expanded, the contents can be easily taken out of the tray by putting a hand under the contents.
[0007]
Further, when the cut line is cut and the cover plate is removed, the rear end face opens, so that the contents can be slid from the opening and transferred to a dish or the like.
[0008]
Furthermore, if a crease line is provided in the lid plate and the bottom plate and the bent state at the time of disassembly along the crease line is maintained by engagement of engagement cuts, the bulk can be reduced and discarded.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings, taking a paper pizza delivery box as an example.
[0010]
In the blank shown in FIG. 1, a cover plate 3 is connected to a rear end edge of the bottom plate 1 via a back plate 2, and the bottom plate 1 and the cover plate 3 are octagonal. On the ridges of the back plate 2, the bottom plate 1 and the cover plate 3, a cut line 4 made of a zipper is provided.
[0011]
Side plates 5 are continuously provided on both side edges of the bottom plate 1, and corner plates 6 and bent pieces 7 are sequentially provided on both side edges thereof. The corner plate 6 and the corner edge of the bottom plate 1 are connected via a folding piece 8, and a winding plate 9 having two folds is connected to the front end edge of the bottom plate 1. The leading edge of the winding plate 9 is provided with a notch 10 at the center portion, projecting pieces 11 on both side portions, and an engagement hole 12 provided on the bottom plate 1 adjacent to the winding plate 9.
[0012]
Side folds 13 are connected to both side edges of the cover plate 3, front folds 14 are connected to the front end edge of the cover plate 3, and a single fold line 15 is provided at the center of the cover plate 3 and the front fold pieces 14. However, two crease lines 16 are formed on the bottom plate 1 so as to reach both sides of the front folding piece 14. Further, the both-side folded piece 13 is formed with an engagement notch 17 composed of perforations inclined in opposite directions.
[0013]
In order to assemble this blank and wrap the pizza, as shown in FIGS. 2 to 4, the side plates 5 are erected from the bottom plate 1, and the corner plates 6 and the folded pieces 7 are sequentially placed inside while folding the folded pieces 8. The front folding piece 7 is held by the winding plate 9 and the protruding piece 11 is inserted into the engagement hole 12 to form the tray T. After storing the pizza inside the tray T, the side folding piece 13 And the front folding piece 14 is inserted in the tray T and sealed.
[0014]
In this paper box, the lid plate 3 is opened, the folding of the rear folding piece 8 is returned, and the folding piece 7 is expanded (see the chain line in FIG. 5). T can be taken out.
[0015]
Further, the cut line 4 is cut and the back plate 2 is cut out, and as shown in FIG. 5, when the cover member F composed of the cover plate 3, the side folded piece 13, and the front folded piece 14 is removed, the rear end face opens. Therefore, the pizza can be slid from this opening and transferred to a plate or the like.
[0016]
Then, after the pizza is taken out, a finger is put on the notch 10 to pull up the tip of the winding plate 9, the side plate 5 is tilted outward, and the tray T is moved along the fold line 16 as shown in FIGS. When folded and sandwiched between the cover member F folded in two along the crease line 15 and the engagement cut 17 is cut and meshed, the folded state around the crease lines 15 and 16 is maintained. Can be discarded.
[0017]
Here, when the paper is thick, if the two crease lines 15 are provided in parallel at some intervals, the folded state of the lid member F sandwiching the tray T becomes difficult to return.
[0018]
Alternatively, the crease line 16 may be provided only in the center of the bottom plate 1 and the engagement cut 17 may be formed also in the side plate 5 so that the tray T and the lid member F are separately locked and discarded.
[0019]
Further, if the cut line 4 is provided only on the bottom plate 1 side, the back plate 2 remains connected to the lid plate 3, so that the cut back plate 2 is not dissipated.
[0020]
【The invention's effect】
As explained above, in the paper box according to the present invention, when the cover plate is opened and the rear bent piece is expanded, the contents can be easily removed from the tray by putting a hand under the contents, Further, when the cut line is cut and the cover plate is removed, the rear end face opens, so that the contents can be slid from the opening and transferred to a dish or the like.
[0021]
Furthermore, if a crease line is provided in the lid plate and the bottom plate and the bent state at the time of disassembly along the crease line is maintained by engagement of engagement cuts, the bulk can be reduced and discarded.
