Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a paper box that can store products, and particularly to a top lid opening/closing box that is easy to assemble.

<Prior art> This type of top lid opening/closing box has already been developed by the applicant of the present invention and has been registered as a utility model.
The one shown in the above publication is publicly known.

In this technology, a lid consisting of a lid plate, a rotating plate, etc. is provided on the left and right sides of the box, and by sliding the rotating plates along the outer surface of the end plate of the box, the box can be opened and closed over a wide range. This is the technology of the constructed box.

In particular, in the box mentioned above, a rotating plate is drilled in the end plate, and the rotating plate is moved by sliding the locking piece along the rotating plate protruding from one corner of the rotating plate. By rotating the outer surface of the end plate, the lid can be opened and closed at the opening of the box.

<Problem to be solved by the invention> However, in the box described above, when assembling the box by inserting the locking piece into the rotating plate, the upper end of the rotating plate is located at the center of the rotating plate. Since the locking piece is bent closer to the end plate, in order to insert the locking piece protruding from the rotating plate into the rotating plate, insert the locking piece while curving it almost at right angles to the end plate. Otherwise, it would not be possible to insert the locking piece into the rotating plate and attach the rotating plate to the end plate.

Therefore, in the conventional technique described above, during assembly, the locking piece must be inserted into the rotating plate while being curved at a predetermined angle, and the locking piece must be attached to the rotating plate so that it does not slip out. However, if you are not skilled and have poor workability, you may end up bending the locking piece into a dog shape.
Even if the locking piece is inserted into the rotating plate, there is a drawback that when the rotating plate is rotated, the locking piece will come off due to the rotating plate.

The box according to the present invention is a completely new technology that fundamentally improves the above-mentioned drawbacks of the conventional technology. This technology allows for extremely smooth insertion into the body.

<Means for Solving the Problems> The present invention is a technology that fundamentally improves the problems of the conventional technology described above, and its gist is that the bottom plate is centered, and a side plate, a cover plate, and an inner cover are installed on the left and right sides of the base plate. Connect the plates and tongue pieces in order, connect the end plates to the top and bottom of the bottom plate, respectively,
A blank plate formed by connecting rotary plates with bendable clamping plates on the outer edges of the side plates is sequentially folded to form a cover plate connected to the side plates and a rotary plate engaged with the cover plates. In a box assembled in such a manner that the rotating plate covers the opening of the box and rotates along the outer surface of the end plate, a locking piece protrudes from an upper corner of the rotating plate on the end plate side. Y-shaped notches are provided on the left and right sides of the end plate, the upper part of which branches into a V-shape, and into which the locking piece can be slidably inserted;
The upper branching portion of the glyph-shaped cut is composed of a portion farthest from the center of the rotary plate and a portion close to the center.

<Function> In the present invention, as mentioned above, since the Y-shaped notches 8 are bored on both sides of the end plate 7, the Y-shaped notches 8
When inserting the locking piece 9 of the rotating plate 10 into from the outside (when the rotating plate 10 comes into contact with the end plate 7, the tip of the locking piece 9 automatically adjoins the far branching part of the Y-shaped notch 8). As a result, the locking piece 9 can be inserted into the Y-shaped notch 8 while maintaining a substantially straight line without curving the locking piece 9.

Once the locking piece 9 is inserted into the Y-shaped notch 8, when the rotary plate 10 is rotated to tilt the lid outward in order to open the lid, the locking piece 9 moves as the rotary plate 10 moves. 9
The tip of the Y-shaped notch 8 moves smoothly to the nearer part than the farthest part, thereby making it possible to open the lid wider.

<Example> An embodiment of the box according to the present invention will be explained in detail with reference to the drawings. In FIG.
A lid plate 4, an inner lid plate 5, and a tongue piece 6 are connected in this order, and end plates 7 are connected on both sides of the top and bottom of the bottom plate 2, respectively. character-shaped notches 8 are perforated, and the side plate 3
Rotating plates 10 having locking pieces 9 at the corners are connected to both sides of the rotating plate 10, and clamping plates 11 are connected to the side edges of the rotating plates 10.

As is clear from the figure, the upper part of the Y-shaped notch 8 is branched into a V-shape, one of which is a part far from the center of the rotating plate 10, and the other is a part of the rotating plate 10. It is composed of parts closer to the center.

Therefore, the locking piece 9 of the rotary plate 10 inserted into the far part of this Y-shaped notch 8 can be automatically moved from this far part to the near part as the rotary plate 10 rotates. It is configured.

Since the basic structure of the box according to the present invention is the same as the above-mentioned known technology, other detailed explanations will be omitted.

Next, when assembling the box of the present invention, as shown in FIGS. 3 to 6 and FIG. 4 and sandwich it with the inner cover plate 5, and then bring the rotating plate 10 to the outside of the end plate 7, and attach the locking piece 9 of this rotating plate 10 to the Y of the end plate 7.
Insert deeply from the far branched part above the character-shaped notch 8 to the nearer part gradually, and connect this locking piece 9 and Y
In combination with the letter-shaped notch 8, the rotary plate 10 can be assembled so as to be able to slide along the outer surface of the end plate 7.

In the above embodiment, the assembly of inserting the locking piece 9 into the Y-shaped notch 8 will be explained as follows.

That is, when inserting the locking piece 9 into the Y-shaped notch 8, as shown in FIG. Place the tip of the locking piece 9 adjacent to the outside of the upper branched far part of the Y-shaped notch 8, and in this state, insert the locking piece 9.
By pressing the tip of the Y-shaped notch 8 without bending the locking piece 9,
It can be inserted in the far part of

Next, when the cover is opened while rotating the rotary plate 10, the locking piece 9, which had been inserted into the far part of the Y-shaped notch 8 as shown in FIG. 6, is now moved as shown in FIG. The lid is automatically moved to a part near the Y-shaped notch 8, as shown in the figure, and thereby the lid can be opened smoothly.

When using the box of the present invention, as shown in FIG. 2, by sliding the rotating plate 10 along the end plate 7, the lid can be opened widely to the left and right.

<Effects of the invention> Since the box according to the invention has the structure and function as described above, the locking piece provided on the rotating plate can be inserted into the end plate without bending or bending. It can be smoothly inserted into the Y-shaped notch and rotatably locked in the Y-shaped notch.

Therefore, it has features such as extremely good workability, the ability to prevent the production of defective products during assembly, and the lid having a wide left and right opening that can be opened smoothly.
