Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a cardboard trash can that is used by covering the storage compartment with a garbage bag made of plastic or the like, and is particularly a disposable trash can that can be used outdoors for at least one week. Regarding garbage cans.

[Conventional technology]

Conventionally, as for this kind of cardboard trash can, Japanese Utility Model Application Publication No. 49-20373 has a raised bottom part, and Japanese Utility Model Application Publication No. 63-31001 has a thin vinyl box inside the assembled paper box. Each of these papers discloses a waterproof paper box that is attached to a wall and is secured to a hook portion of a holder attached to a wall.

[Problem that the invention attempts to solve]

However, the raised bottom of the cardboard trash can of Utility Model Application Publication No. 49-20373 is composed of a bottom plate that is separate from the outer wall plate (outer cylindrical body) forming the square cylinder; Fixing this bottom plate is
The upper end of the folded part obtained by folding the lower end of the outer cylinder inward, and the inner wall plate (inner cylinder) arranged inside the outer cylinder.
Since the structure is assembled by inserting and engaging the locking protrusion of the bottom plate into a notch formed at the joint with the lower end of the box, the work of fixing the bottom plate by the engagement is performed inside the box.

Therefore, assembly work is difficult and inefficient; the bottom plate is formed of a separate member from the outer cylinder, and a separate inner cylinder is required to solidify the bottom plate, and the material Since the bottom plate is fixed by engagement with both the inner and outer cylinders, the vertical supporting force is structurally small.
There are various problems.

In addition, the method of fixing the disposable toilet corner to the wall surface of Japanese Utility Model Application Publication No. 63-31001 is to fix a hook member separate from the box with a double-fold structure to one side of the upper opening of the box. Because of its structure, it requires material for the hook member, its formation, installation work, etc., and as the name suggests,
The main purpose is to fix it to a wall surface, and there are various problems such as the fact that it cannot be used for fixing it on the ground outdoors.

[Means for solving problems]

The present invention was developed in order to solve the conventional problems as described above, and in particular, it is strong enough to be used outdoors for at least several days to about a week, and is fixed to the ground. The purpose of this is to provide a low-cost product that can be used for storage, and the gist thereof is to insert a garbage bag 30 into the storage section 5 from the upper opening 2, as shown in the embodiment of the drawings.
The storage part 5 is composed of a foldable side wall part 3 and a raised bottom part 4. Folded line 13 at the bottom edge of
Each reinforcing piece 12 extending through the fold line 1
a reinforcing rib 6 that protrudes downward and is formed by folding upwardly inward from 3; and each of the reinforcing pieces 12;
Each of the flaps is provided with a raised bottom plate 7 formed by horizontally folding back the flap pieces 15 to 17 extending from the fold line 14 outward from the fold line 14 at the lower end thereof. This trash can made of cardboard is characterized in that an insertion hole 8 through which an anti-falling material for fixing the trash can 1 to the ground is inserted is bored at a forming position.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in FIGS. 1 to 4. In addition, FIG. 1 is a perspective view showing an example of the usage state of the cardboard trash can according to the present invention, and FIG. 2 is a sectional view taken along the line A-A in FIG. 1.
FIG. 3 is an exploded view of the trash can, and FIG. 4 is an explanatory view of the assembled state.

In the figure, reference numeral 1 denotes a cardboard trash can, which is a bottomed box with an opening 2 at the top, and which is composed of foldable surrounding side walls 3 and a raised bottom 4. The side walls 3 and the raised bottom 4 divide the trash can into a storage area 5.
The raised bottom portion 4 is formed as follows:
The lower end of the side wall plate of the side wall portion 3 is folded back inward and upward to project a reinforcing rib 6 downward, and the reinforcing rib 6 is further folded horizontally outward to form a bottom plate 7.
At the positions where the reinforcing ribs 6 are formed, insertion holes 8 for inserting anti-toppling materials are formed. In addition to the above-mentioned insertion holes 8, insertion holes 9 may be formed in the corners of the side wall portions 3.

More specifically, the cardboard trash can 1 is made of a piece of cardboard as shown in the exploded view of FIG. It is made of bent cardboard that is coated with water-repellent paint. That is, in the developed view of FIG. 3, each side wall part 10 constituting the side wall part 3 is divided into foldable sections sequentially through three fold lines 11, and a reinforcing rib 6 is formed at the lower end of each side wall plate 10. Reinforcement piece 12 is broken line 1
3, respectively. Further, from the reinforcing piece 12, a concave flap piece 15 for forming the bottom plate 7 and a triangular flap piece 1 are inserted through the fold line 14.
6, 16 and a convex flap piece 17 are provided in series. In addition, 18 in the figure is a glue allowance.

As shown in FIG. 4, the order of assembly of this cardboard trash can 1 is as follows: First, the concave flap piece 15 is folded back, and then the concave flap piece 15 is turned upside down, and then the cardboard box 1 is made into a cylinder by being glued with the glue 18. Flap piece 1
6, 16 are folded back, and finally the convex flap piece 17 is placed on the flap and pressed, the convex piece 19 of the convex flap piece 17
passes through the concave portion 20 of the concave flap piece 15 and engages in the concave flap piece 15, so that the raised bottom plate 7 is formed horizontally. Further, the reinforcing piece 12 and the flap pieces 15 to 17 can be folded inward from the fold line 13 in advance, so that the side wall plate 10 and the reinforcing piece 12 can be integrated. In this case, it is desirable to integrate the insertion hole 8 with a caulking metal fitting 21 to reinforce the periphery of the insertion hole 8. An inner frame piece 23 for concealing the end face is extended from the upper end of the side wall plate 10 via the fold line 22, and the inner frame piece 23 for concealing the end face is connected to the fold line 2.
If the cardboard is folded back inward from the part 2, the end surface of the cardboard is not exposed upward, so that it is possible to prevent rain, etc. from directly entering the inside, and it is also possible to strengthen the bending reinforcement of the opening 2.

When using, for example, use a plastic garbage bag 3
0 into the storage section 5, folding the bag 32,3
2 is folded back from the opening 2 to the outside of the side wall 3. Then, if necessary, a slip-off prevention clip 32 is fitted from the outer wall portion 3 to the upper end. At that time, fall prevention members 24, 24 can be inserted into the insertion holes 8, 8 and fixed to the ground E. As the fall prevention material 24, it is sufficient to drive a roughly 7-shaped nail, and if necessary, a fall prevention material 25 such as a string or wire may be inserted into the insertion hole 9 drilled in the corner of the side wall 3. It may also be inserted and fixed to a T such as a standing tree. Note that if a cardboard box coated with water-repellent paint on both surfaces is used, only the garbage bag 30 can be replaced and used repeatedly, making it ideal for relatively short-term events.

[Effect of idea]

As described above, the cardboard trash can according to the present invention has a garbage bag 30 inserted into the storage section 5 from the upper opening 2.
The storage part 5 is composed of a foldable side wall part 3 and a raised bottom part 4. Folded line 13 at the bottom edge of
Each reinforcing piece 12 extending through the fold line 1
a reinforcing rib 6 that protrudes downward and is formed by folding upwardly inward from 3; and each of the reinforcing pieces 12;
Each of the flaps is provided with a raised bottom plate 7 formed by horizontally folding back the flap pieces 15 to 17 extending from the fold line 14 outward from the fold line 14 at the lower end thereof. Since the construction is such that an insertion hole 8 is formed at the formation position through which the anti-falling material for fixing the garbage can 1 to the ground is inserted, it can be formed from a single piece of cardboard, and moreover, by bending it. Can be assembled easily. Therefore, not only can material costs be reduced, but assembly work is also easy. In addition, the insertion hole through which the anti-falling material for fixing the trash can to the ground is drilled at the position where the reinforcing rib is formed by folding back the reinforcing piece to create a double structure, so it has great structural strength. Since this insertion hole is located close to the grounding part of the trash can, it is possible to firmly fix the trash can to the ground, reliably preventing the trash can from falling over due to wind or human causes. Since the upper part and the bottom part are foldable, it is not bulky and can be easily transported, and when discarded, it can be disposed of without being bulky.
