Description

[Detailed Description of the Invention] The present invention relates to a paper box suitable for disposable waste boxes and the like.

BACKGROUND ART Conventionally, for example, trash boxes, dust boxes, and garbage containers are known as being either stationary or equipped with a stand on which a replacement bag made of paper or plastic film can be placed. The disadvantages of this method are that it is very costly in terms of production to have a device that automatically closes the lid after putting debris and dust into the box, and if the box is full of trash, the box must be turned upside down. It is disposed of by taking it out or scooping it out, which requires effort to clean.
They are also poor in terms of hygiene, and replacement garbage bags require time and effort to put on lids, and since they usually do not have lids, they cannot block out the odor of filth, and their appearance is extremely undesirable.
However, they have the advantage that they can be used semi-permanently except for replacement garbage bags.

The product of this invention is easy to assemble, there is very little liquid leakage from the bottom, it closes automatically so it can block out odors from dirt, etc., and it is disposable because the main material is paper so that the dirt inside cannot be seen from the outside. However, the economic burden is extremely small.

Conventional products are made of resin, wood, bamboo, etc. and can withstand semi-permanent use, but as mentioned above, they are labor-intensive and unhygienic, and the lids are either open-type or automatic-opening types, but they are expensive. It is heavy and bulky, and requires a considerable amount of storage space.

The product of this invention is made of paper or paper laminated with aluminum film, plastic film, etc., and when used as a waste box, for example, it is disposable, non-polluting, does not require cleaning, and is hygienic. Automatic opening/closing type, easy assembly, inexpensive materials, and extremely low cost. It is light and bulky, does not require much space, and can be easily assembled when in use.

The invention will now be explained by means of illustrated embodiments.
FIG. 1 is a developed view of the disposable waste box of the present invention.

First, front plate 1, side plate 2, back plate 3, side plate 4
are provided sequentially through the broken lines. A gluing piece 5 is provided on the leading edge of the front plate 1 via a fold line. An adhesive piece 6 is also provided on the lower edge of the front plate 1 via a fold line. Next, in order to form a bottom, a bottom plate 7 is provided on the lower edge of the back plate 3 via a fold line, an insertion flap 8 is provided on the leading edge of the bottom plate 7, and side plates 2 and 4 are attached from both ends of the leading edge of the bottom plate 7. Triangular flap 9 on each line leading to the tip,
9', and a fold line 10, 10' connecting the center of the base of this triangular flap to the apex of the base of the back plate 3 is provided.

A small rectangular flap 11 having a width approximately half the width of the paper box opening is provided on the upper edge of the back plate 3 via a fold line, and locking pieces 12 are provided projecting from the upper ends of both sides thereof. On the upper edge of the front plate 1, which is the facing surface of the back plate 3, there is provided a large square flap 13 that overlaps the small square flap through a fold, and an eight-shaped ruled line 14 extending from both ends of the base toward the center of the upper side. . Triangular flaps 15 and 16 are provided at the upper edges of the side panels 2 and 4, respectively, at the height of the small square flap 11 via folds, and the tops of the flaps are in contact with the small square flap. , 16 towards the apex of the base 17,1
7' is provided on the hypotenuse.

To prepare such a blank sheet, first adhere the gluing strip 5 to the back side of the side plate 4 by the usual method, and then fold the triangular flaps 9, 9' inward along diagonal fold lines to form the bottom. The top is covered with the bottom plate 7, the insertion piece 8 is inserted inward to form the bottom, and the bottom is fixed by pasting the adhesive piece 6 on top of the insertion piece 8, which is the external view shown in Fig. 2. The state shown in is reached. Next, push down the large square flap 13 inward as shown in the external view in Figure 3, fold the triangular flaps 15 and 16 flat inward, stack the small square flap on top of it, and gently push it downward. and locking pieces 12, 12'
are inserted into the notches 17 and 17', respectively, and are naturally locked, forming a waste box as shown in FIG.

Note that the notches 17 and 1 of the triangular flaps 15 and 16
7' and the small square flap with the locking pieces 12, 12', and then the large square flap 13 can be pushed down all at once to the lowest position to assemble it in the same way.

To throw in trash and debris, push the tip of the large square flap below, and the leading edge will descend to open as shown in the external view of Figure 5 (shaded area).
When the force is released, it will restore and close as shown in Figure 4.
Although this repulsive force depends on the material, it is also due to the action of the eight-shaped ruled lines 14 on the large square flap, and these ruled lines 14 also serve to prevent curling.
