Description

[Detailed description of the invention] [Field of industrial application] This invention makes it easy to open and close the lid when putting in and disposing of waste, etc., and by ensuring the independence of the lid plate, staining of the opening area can be avoided. This waste disposal paper box is designed to be clean and hygienic.

[Conventional technology]

Conventionally, toilets and kitchens in public buildings where the general public enters and exits, corporate buildings, etc., as well as toilets and washrooms in ordinary households, are usually made of plastic, enameled iron, or ceramic. Containers such as those made of aluminum have been used for disposing of filth and the like.

Looking at examples of use in ordinary homes, today's products are not just for practical purposes, but are high-quality items that are designed with an emphasis on interior design, reflecting the affluent standard of living.

By the way, in the case of waste disposal containers made of the above-mentioned materials, the reality is that the items that are put in and disposed of are often items that tend to emit strange odors, or items that should be kept out of sight as much as possible and cleaned up frequently. be.

Therefore, thorough cleaning within a short period of time is required, and as a result, the operator is required to take the time and effort necessary to do so, and must endure the discomfort caused when removing the waste, cleaning, and disinfecting. Nakatsuta.

For this reason, for example, Japanese Utility Model Publication No. 60-38561 (Paper Waste Box) has the advantages of being non-polluting, requiring no cleaning, disposable, hygienic, and has an automatically opening/closing lid. , Jitsugyo 61-
Various proposals have been made, such as those seen in Publication No. 13441 (paper box) and Publication of Utility Model Application No. 60-69201 (assembly-type mens board case for processed materials).

[Problem that the invention attempts to solve]

However, there are still unresolved problems with the functionality and hygiene of the automatic opening/closing type lid.

In other words, as seen in the above-mentioned paper waste box, the type in which the opening/closing lid is pressed from the outside and scraps are thrown in, and the opening/closing lid is reclosed using the repulsive force of the paper, is the first type. Although it is guaranteed that the automatic opening and closing will be done as intended several times,
Unless it is made of highly flexible paper material, if it is provided as a frequently used waste box, the horizontal fold line between the horizontal plate and the opening/closing lid will not be able to fulfill its function as a hinge, It is easy to imagine that the lid will not return to its original position. Furthermore, it is difficult to throw in waste without contaminating the surface of the opening/closing lid.

Furthermore, since the above-mentioned paper box is made of paper, it has great advantages in terms of being non-polluting, requiring no cleaning, and being inexpensive when compared to the above-mentioned plastic waste containers. However, due to its mechanism, by pushing the tip of the large rectangular flap downwards, the front edge of the flap opens and descends, so as with the above, you can always throw in waste without touching the opening. It is extremely difficult to do so, and since the design places emphasis on closure and the input opening is narrow, it can contaminate not only the opening/closing flap but also other surrounding flaps, causing discomfort and being unhygienic. Ta.

In addition, the opening of the case is a prefabricated type, with both sides of the lid fixed and opened and closed by pulling up the tip of the lid plate. It was necessary to hold the tip of the lid with a handle, making it difficult to concentrate on putting in the waste, and it lacked convenience.

Moreover, the opening of the lid body is narrow and there is the same problem of contamination as mentioned above, and the opening of the lid itself cannot be maintained or it cannot be expected to open and close automatically.

[Means for solving problems]

In the present invention, the longitudinal section is bent into a V-shape by providing a crease in the sliding lid plate, and the engaging protrusions formed on both side edges of the sliding lid plate are L-shaped on each side lid piece. The sliding lid plate opens and closes according to the guide part by being inserted into and engaged with the guide part of the lid plate. It is a waste disposal paper box that can achieve the effects described below, such as automatic opening/closing and self-reliance, convenience of use, and overcoming hygiene problems. The upper edge of the front wall of the main body of the box is divided into two parts, a covering part and a pressing part, with a crease serving as the bending axis of the valley fold as the border, and both lower sides of the covering part adjacent to the fold. In an outer box in which a sliding lid plate having engaging protrusions protruding from the front wall is connected to the left and right sides of the front wall through folds; A side cover piece is provided on each upper edge with an L-shaped slit or groove guide portion into which the engaging protrusion is inserted and engaged, and the side cover piece is connected via a fold, and the engaging protrusion is inserted into the L-shaped side cover piece.
The present invention is characterized in that the sliding lid plate is opened and closed by reciprocating the letter-shaped guide portion.

Furthermore, it functions as a covering piece when the lid is closed.

Reference numeral 10 denotes an adhesive part connected to the rear wall 1 described above, and is fixed along the side edge of the right side wall 2b.

Reference numerals 13a and 13b are bottom portions that are connected to the lower edges of the left and right side walls 2a and 2b through folds 19b and 19d, respectively, and there are a pair of slits 14 and 13b.
4 is provided.

15 is a fold 19c on the lower edge of the front and rear wall portions 3 and 1;
19a, and the deterrent piece 1
5 and 15 are formed into an inverted trapezoidal shape, and locking protrusions 16 are attached to the right and left side edges of the approximately central portion thereof, and the locking protrusions 16 are fitted into the slits 14, 14.

Note that the bottom structure is not limited to the illustrated example, and a well-known and commonly used structure that can be unlocked may be adopted.

The inner bag B shown in Figures 4 and 5 is made of plastic film, and is usually made of polyethylene film, but depending on the intended use, it may be made of aluminum, taking into account its waterproofing, moisture-proofing properties, and properties against the contents. It is selected as appropriate depending on the contents to be accommodated, such as laminating other materials.

In Figure 4, the part drawn by the two-dot chain line is
This is an example of the fixation points S of the inner bag B to the inner surfaces of the front and rear walls 1 and 3 of the outer box A.

Therefore, the opening edge of the inner bag B is placed on the inner surface of the opening edge of the outer box A, and the bottom of the inner bag B is gathered together at the lower side of the outer box A with some space, and when the outer box A is assembled, the inner bag is automatically The opening is designed to expand. In addition, the inner bag opening edge is connected to each wall portion 1, 2a, 3, 2 of the outer box.
Even if they are not accurately fixed to the upper inner surface of b, the sliding cover plate, side cover pieces, and reinforcing pieces connected to the upper edge of each wall are folded inward, so the inner bag opening can be maintained fully expanded. This makes it possible to quickly put waste into the inner bag.

The present invention having the configuration as described above is based on the following compositional procedure, and brings about the effects described later.

That is, as one aspect when implementing the assembly of the present invention, as shown in the fourth illustrated example,
The inner bag B is fixed to the inside of the front and rear wall parts 1 and 3. The assembly consists of folds 17a, 17b, 17c, 17
d, and the adhesive part 10 is fixed to the back surface of the right side wall part 2b to form a rectangular tube shape.

Next, the restraining pieces 15, 15 are folded to cover the inwardly bent bottom parts 13a, 13b, and the locking protrusions 16, 16 are folded.
are inserted and fitted into each of the slits 14 in the bottom portions 13a and 13b.

After doing so, first fold the reinforcing piece 8 inward, fold in the side lid pieces 9a and 9b so that they face each other, and then fold the sliding lid plate 4 through the fold 18c into the upper surface of the reinforcing part 8 and the side lid pieces 9a and 9b. to cover up.

During this covering, each engaging protrusion 7a, 7b is connected to each guide portion 12 of the corresponding side lid piece 9a, 9b.
By inserting and engaging the lid, the lid is kept closed and the assembly is completed (FIG. 1).

When using to throw in waste, etc., by lightly pushing the pressing part 6 downward with your finger, the sliding cover plate 4 is valley-folded along the fold 11 of the bending shaft, and the covering part 5 and the pressing part 6 are folded. It changes into a V-shaped cross section, as if it were divided into two (Figure 2).

The process of changing into the V-shape is due to the fact that the waste disposal paper box of the present invention is made of paper, and as the pressing part 6 presses, the engaging protrusions 7
a, 7b are moved and guided along the guide part 12 while engaging with the slit starting end → 12a → 12b,
Sliding lid plate 4 bent at an acute angle at its end
will remain free standing at the end point. Even though the guide part 12 is linear and has an L-shape, it is made of flexible paper. The slits or grooves are held in place, and are moved and guided along the guide portion 12 while pressing and bending the inside of the slit or groove from beginning to end. The sliding lid plate 4 is made to stand on its own at an angle.

If you wish to close the lid after putting in the waste, just pinch the tip of the sliding lid plate 4, that is, the side end of the covering part 5, and pull it upward, and the engaging protrusions 7a and 7b will immediately engage with the inclined slit 12b. As the connection is released, the V-shaped state gradually returns to the horizontal state, and the lid is closed again. Even when the lid is closed, the upper and lower surfaces of the engaging protrusion are held between the slit opening end surfaces, so that the lid will not be opened inadvertently.

Further, since the side lid pieces 9a, 9b tend to stand up due to elastic restoration, the engaging protrusions 7a, 7b and the guide portion 12 engage extremely tightly.

After the filth is added, the disposal process is carried out at an appropriate time.

〔effect〕
