Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packaging box for sealing a lid plate by insertion.
[0002]
[Prior art]
For example, a box as shown in FIG. 6 is used as a box for packaging a small video camera or the like. This packaging box is provided with an insertion piece 51 at the front end of a cover plate 50 that undulates with the rear end as an axis, and forms a slit-like insertion port 54 at the base of a flap 53 extending from the upper end of the front wall 52, A lid receiving piece 56 is extended from the upper end of the side wall 55.
[0003]
In order to seal the packaging box, the lid receiving piece 56 is folded inward, the flap 53 and the lid plate 50 are sequentially stacked thereon, the insertion piece 51 is inserted into the insertion port 54, and the shoulder of the insertion piece 51. The part 57 is engaged with the edge of the insertion port 54.
[0004]
And when opening this packaging box, a finger is put on the edge of the cover plate 50 projecting forward on both sides of the insertion piece 51, and the tip of the cover plate 50 is pulled up.
[0005]
[Problems to be solved by the invention]
However, in such a packaging box, since the cover plate 50 cannot be pulled up directly, the engagement between the shoulder portion 57 of the insertion piece 51 and the edge of the insertion port 54 is difficult to disengage and is difficult to open. There's a problem.
[0006]
In addition, the outer dimension of the box increases due to the overhang of the cover plate 50, and there is a problem that it becomes bulky during transportation and storage.
[0007]
Then, this invention makes it a subject to provide the packaging box which is compact and easy to open.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, in the present invention, the lid plate is overlapped on the flap extending from the front wall, the insertion piece at the tip of the lid plate is inserted into the insertion port of the base of the flap, and the shoulder portion of the insertion piece is attached. In the packaging box to be engaged and sealed with the edge of the insertion slot, the insertion slot is cut to the front end side of the flap, and the width of the cut section is set larger than the width of the shoulder of the insertion piece, When a push piece is provided on the upper part of the front wall and this push piece is pushed, the insert piece bends backward and escapes to the notch of the insert, and the shoulder of the insert and the edge of the insert The engagement was disengaged.
[0009]
Since such a packaging box can be opened simply by pressing the pushing piece, it is not necessary to project the cover plate from the front wall and can be made compact.
[0010]
Instead of the pushing piece, a notch portion may be provided in the upper portion of the front wall, and the inserting piece may be bent backward through the notch portion.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0012]
In the blank shown in FIG. 1, side walls 2 are continuously provided on both sides of the front wall 1, and a rear wall 3 and a passage piece 4 are sequentially provided on the outside of one side wall 2. A bottom piece 5 is provided at the lower end of each side wall 2, and a bottom plate 6 is provided at the lower ends of the front wall 1 and the rear wall 3. A lid receiving piece 7 is provided at the upper end of each side wall 2, and an upper end of the front wall 1 is provided. A flap plate 8 and a lid plate 9 are connected to the upper end of the rear wall 3, respectively.
[0013]
An insertion piece 10 is connected to the tip of the lid plate 9 and shoulders 11 are provided on both sides thereof. An insertion port 12 is formed at the base portion of the flap 8, and the width of the cut portion 13 toward the distal end side of the flap 8 is larger than the width of the shoulder portion 11 of the insertion piece 10. A pushing piece 14 is formed between the two cuts on the upper portion of the front wall 1.
[0014]
As shown in FIG. 2, the front wall 1, the side walls 2 and 2 and the rear wall 3 are bent into a rectangular tube shape, and the passage piece 4 is opposite to the side wall 2 on the opposite side. The bottom wall is closed by combining the bottom piece 5 and the bottom plate 6.
[0015]
Next, the product is stored in the box, the lid receiving piece 7 is folded inward, the flap 8 and the lid plate 9 are sequentially stacked thereon, the insertion piece 10 is inserted into the insertion opening 12, and the insertion piece 10 The shoulder 11 is engaged with the edge of the insertion port 12.
[0016]
In such a packaging box, the lid plate 9 is locked and securely sealed in the packaging state, and at this time, the size is set so that the front end portion of the lid plate 9 does not protrude from the front wall 1. It is not bulky during transportation or storage.
[0017]
Then, when opening, as shown in FIG. 3, just by pushing the pushing piece 14, the inserting piece 10 bends backward and escapes to the cut portion 13 of the inserting port 12, and the shoulder portion 11 of the inserting piece 10. Since the engagement with the edge of the insertion port 12 is disengaged, as shown in FIG. 4, the lid plate 9 rises with a repulsive force, and the product can be taken out.
[0018]
When the product is stored in the box after opening, when the cover plate 9 is closed and the insertion piece 10 is inserted into the insertion slot 12, the shoulder 11 of the insertion piece 10 is again inserted into the insertion slot. Since the repulsion of the cover plate 9 is suppressed by engaging with the 12 edge, it can be resealed in the same state as the first sealed state.
[0019]
In addition, in this packaging box, since the cover plate 9 cannot be opened unless the pushing piece 14 is pushed from the front rather than from the top, the cover plate 9 is opened by mischief or the like at the time of display at the store, and the commercial value is impaired. There is little fear.
[0020]
In place of the pushing piece 14, as shown in FIG. 5, a notch 15 is provided in the upper part of the front wall 1, and the inserting piece 12 can be directly pushed through the notch 15 and bent backward to be opened. You may do it.
[0021]
【The invention's effect】
As described above, in the packaging box according to the present invention, it is only necessary to bend the insertion piece backward via the pushing piece or the notch provided on the front wall upper portion, and the shoulder of the insertion piece and the edge of the insertion port. And the cover plate is opened so that opening is extremely easy, and there is no need to provide a finger-hanging overhang or the like, and a compact packaging can be achieved.
