Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a paper box that can store various contents, and more particularly to a paper box that can be sealed or opened with one touch.

[Prior Art] Conventionally, as a paper box of this type, for example, SAIkai 57-92618
And those disclosed in Japanese Utility Model Publication No. 58-50733 are known. The structure of the former is shown in FIG. 12 and the structure of the latter is shown in FIG.

In the conventional paper box of this type shown in FIGS. 12 and 13, two lid plates 32 and 32 'with two handles (36) connected to each other on the upper and lower front and back plates 31 and 31' facing each other are mutually attached. The locking plates 33, 33 ', which are arranged one over the other on the upper end of the side plate 34, are bent over the V-shaped folds 37, and the tips of the locking plates 33, 33' are stacked. The part is pushed into and fixed in the notch 35 provided in the upper part of the side plate 34.

[Problems to be Solved by the Invention] However, the conventional paper box having the above-described configuration has locking plates 33, 3
Since each of the 3'is engaged with the side plate 34 and the engagement with the side plate 34 is half, the engaging force is weak and there is a problem that the opening is performed carelessly. In addition, the cost is high because two lid plates with handles are required.

The present invention has been made in view of the above conventional problems, and it is possible to firmly seal the opening after storing the contents, and to perform the sealing and opening operations with one touch, and further to reduce the material cost. The purpose is to provide a paper box made into

[Means for Solving the Problems] In order to achieve the above object, a paper box according to the present invention is a prefabricated paper box including at least a front plate, a rear plate, left and right side plates, a lid plate and a bottom plate. The upper edge and the side edge of the lid plate are provided with a folding plate that is continuous with these and has an oblique folding curve extending diagonally from the intersection of the upper edge of the side plate and the side edge of the lid plate, and at the top of the side plate. It is characterized in that a tip end portion of a folded portion formed when the folding plate is folded is pushed inward and a locking cutout hole for locking this is formed.

[Operation] According to the present invention, after the contents are stored in the box body, the folding plate is folded and the tip end thereof is pushed into the locking notch hole on the upper side plate to be locked. ing. By doing so, the entire tip portion of the folded portion is firmly fixed in the engaging cut hole, so that there is no inconvenience such as inadvertent opening. Further, the box can be opened easily by simply pulling the protrusion provided on the folding plate. in this way,
The lid can be closed and opened with one touch by simply engaging and disengaging the folded part at the top of the box.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a perspective view before completion of assembly, and FIG. 3 is a developed plan view of the same.

In FIG. 3, a rear plate 1, a side plate 2, a front plate 3, a side plate 4 and a sticking piece 5 are sequentially connected to each other through vertical folding curves a to d, and a lid is attached to an upper edge of the front plate 3. The plate 6 has a bent curve e
The hanging plates 7 having the hanging holes 8 are connected in series through each other. Further, the front plate 3 is provided with a window portion 18 having an arbitrary shape, and a transparent sheet can be attached to the window portion 18. Further, the upper edges of the left and right side plates 2 and 4 and the side edges of the lid plate 6 are continuous with these and oblique from the intersections of the upper edges of the side plates 2 and 4 and the side edges of the lid plate 6, respectively. Direction (45 in this example)
Folding plates 9 and 9 each having a projecting piece 10 on the end nearer to the side edge of the cover plate 6 are provided at the upper portions of the side plates 2 and 4. On the upper edges of these, substantially U-shaped engaging cut holes 11, 11 are formed, and the vertical cuts 12, 12 are formed at the lower ends of the cut holes 11, 11 in this embodiment.
Has been drilled. Further, a suspension plate 13 having a suspension hole 14 having the same size as the suspension hole 8 is continuously provided on the upper edge of the rear plate 1, and the suspension plates 13 are provided at the lower ends of the front and rear plates 3,1 and the left and right side plates 2,4. Is the bottom plate
15,16,17 are connected respectively.

In assembling the paper box of the present invention, first, the front and rear plates 3, 1, the left and right side plates 2, 4 and the sticking piece 5 are bent one after another in a predetermined direction through a vertical folding curve, and then the sticking piece 5 is formed on the back plate. When it is attached to the inner surface side of 1, and then the bottom plates 15, 16 and 17 are engaged with each other to assemble the bottom portion, the form becomes as shown in FIG. Subsequently, the cover plate 6 is bent inward, and the folding plate 9 is folded along the oblique folding curve f to the outer surface of each upper end of the side plates 2 and 4 in a substantially triangular shape.
Insert the tip of this folded part into the notch 11 for locking on the side plates 2 and 4.
When it is pushed in and locked, the assembly of the paper box of the present invention is completed, as shown in FIG. The contents may be stored before closing the cover plate 6 described above. As a result, the folding plate 9 is securely locked and fixed in the locking slit 11 in the folded state, and the paper box can be sealed.

Next, when opening the paper box, the protruding piece projected on the folding plate 9
By pulling 10 outward, the folded portion is pulled out from the inside of the cut hole 11, and the lid plate 6 can be lifted and opened.

4 to 6 show another embodiment of the present invention, in which the cover plate 6
An insertion piece 19 is provided on the upper edge of the back plate 1, and the hanging plate 13 on the upper part of the rear plate 1 has a two-folded structure.

Also, FIGS. 7 to 9 similarly show another embodiment of the present invention, which has a structure without a hanging plate.

Further, FIGS. 10 and 11 also show another embodiment of the present invention. By changing the angle θ of the diagonal folding curve f of the folding plate 9, the lid plate 6 is tilted from the horizontal position in the assembled state. θ
The structure can be tilted only (note that θ
= 45 degrees, the lid plate 6 is in the horizontal position as shown in the above embodiment).

[Effects of the Invention] As described in detail above, in the paper box of the present invention, the folding plate connected to the upper edge of the side plate and the side edge of the lid plate is folded, and the leading end of the folding plate is provided with the notch for locking the upper side plate. Since it is pushed in and locked, the entire tip of this folded part is firmly locked and fixed in the cut hole, and the tip is disengaged from the cut hole as before, and carelessly. The inconvenience of opening the lid does not occur. Moreover, the box can be easily opened by using the protrusion provided on the folding plate. In this way, one folding part, engagement,
The box can be sealed and opened with a single touch by simply releasing it. Further, the paper box of the present invention has a simple structure in which only one cover plate is required as compared with the conventional structure, so that the material cost can be reduced.
