Description

[Detailed description of the invention] <Industrial application field> The present invention is a packaging box that can be easily filled with drugs, cosmetics, etc., and which cannot be opened from the bottom.

<Prior art> Packaging boxes for enclosing medicines, cosmetics, etc. are made by folding and pasting two bottom plates connected to the front and rear panels, overlapping a folding piece connected to the side panels of the body, or by using a flap. A bottom plate having a diameter of 100 mm is provided in succession on one of the front and rear plates, and a flap is inserted into the inner surface of the other front and rear plates so as to overlap the folding piece.

<Problems that the invention aims to solve> Paper boxes such as the ones mentioned above have many adhesive points and are difficult to assemble, and because they can be opened illegally from the bottom, the sealed medicines, cosmetics, etc. can be pulled out, etc.
The problem was that it was easy to be pranked.

Therefore, the present invention proposes a packaging box that can be easily assembled and filled and cannot be opened from the bottom.

<Means for solving the problem> A bottom plate, a winding plate, and an insert piece are sequentially arranged on the lower edge of the back plate of the rectangular cylindrical body so that the winding plate overlaps the inner surface of the front plate, and the back plate A top plate and a top cover plate are sequentially installed on the upper edge, and the insertion piece of the winding plate is reversely folded at the upper edge of the front plate and inserted into the notch made in the upper part of the front plate, and then the upper cover is attached. A plate is attached to the front plate so as to cover the insertion piece and the notch.

<Function> By arranging the winding plate/insertion piece on the bottom plate in a row, stacking the winding plate on the inner surface of the front plate, and folding the insertion piece reversely at the upper edge of the front plate to engage with the notch in the front plate. , the bottom plate cannot be opened at the bottom.

Furthermore, since the top cover covers the notch in which the insertion piece engages, the product cannot be removed unless the top cover is removed.

<Example> An example of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 3, a top plate 5 and a top cover plate 8 are attached to the upper part of the back plate 2, and a bottom plate 4 and a roll-up plate 6 and an insertion piece 7 having the same height as the front plate are attached to the lower part of the rear plate 2 through folded lines. In addition, the side plate 3, front plate 1, and side plate 3' are sequentially connected to the right side of the back plate, and the inner plate 9 is successively connected to the left side via the fold line, and furthermore, the upper part of the side plates 3, 3' are provided with fold-out pieces 10, 10', and at this time, a notch 11 is provided at the top of the front plate for inserting the insert piece 7.
The front plate is cut into an inverted trapezoid shape from the upper edge of the front plate to the notch 11, and the height of the upper cover plate 8 is made sufficiently larger than the height of the insert piece 7, and the insert piece 7 is tilted on both sides and extends to the tip. It is formed into an arrowhead shape, and the setting conditions for the notch 11 and the insertion piece 7 are such that the length of the notch is shorter than the maximum width of the rolled-up piece, and when the insertion piece is engaged with the notch, the bottom plate is horizontal with the lower end of the body. Shape the blanks that need to be sealed.

Next, fold the bottom plate 4, rolling plate 6, and insert piece 7 on the back plate of this blank, and place the inner plate 9 on top of it.
Then, the front plate 1 and the side plate 3' are further folded on top of that, and the inner plate 9 and the side plate 3' are attached. Next, assemble this in the same way as when forming a normal paper box, fold the insert piece 7 in reverse at the upper edge of the front plate so that the winding plate overlaps the inner surface of the front plate, overlap it with the outer surface of the front plate, and insert the insert. Cut one end 11
Insert and engage.

In this state, products such as medicines and cosmetics are filled, and the top cover 8 provided on the top plate 5 is attached to the front plate so as to cover the notch 11.

In addition to the embodiments described above, the positions of the inner plate 9 and the outer plate 3' may be reversed, and the folded pieces 10, 1 on the side plate
The presence or absence of 0' and the shape of the insertion piece 7 do not matter. Further, the front plate above the notch does not need to be removed, but it is easier to insert and engage firmly if it is removed.

The present invention can be applied to confectionery, stationery, etc. in addition to medicines and cosmetics.

<Effects of the invention> As described above, in the packaging box of the present invention, the winding plate/insertion piece is provided in series on the bottom plate, and the insertion piece is reversely bent at the upper edge of the front plate and engages with the notch in the front plate. Since the top cover covers the notch in which the insertion piece engages, the bottom plate cannot be opened from the bottom, and the product cannot be removed or tampered with unless the top cover is peeled off.

In addition, since the packaging box of the present invention engages the insertion piece with the notch in the front plate, the bottom plate can be fixed without adhesion and can be easily assembled.
