【Example】

 In each of the illustrated embodiments, 10 is a box-shaped main body having a bottom and an open top surface, and a receiving shelf 12 having an upright wall 12 ′ forming a groove 11 on the inner circumference thereof is provided on the upper inner circumference thereof. is there. Although the receiving shelves 12 are provided in a series along the entire inner circumference of the box-shaped body in the illustrated embodiments, they may be provided intermittently or partially. The cross-section of the groove 11 may have a depth of about 10 to 30 mm and a groove width of about 15 to 40 mm. Reference numeral 13 denotes an upper frame having a dust input port 14, and the box-shaped main body 10 and the upper frame 13 are preferably formed of stainless steel plate.

Reference numeral 15 denotes an inner bag which is made of a flexible sheet such as a vinyl sheet and has a bottom reaching the bottom surface of the box-shaped body 10 and accommodated in the box-shaped body. Since the upper peripheral edge of the inner bag is folded outward and inserted into the groove 11 of the receiving rack 12, shallow cuts 15 'are formed at the four corners from the upper end to the bottom so that it can be easily folded outward. It is preferable to keep it.

In FIG. 1 showing the embodiment of claim 1, FIGS. 2 and 3 showing the embodiment of claim 2, and FIGS. 4 and 5 showing the embodiment of claim 3, the peripheral wall of the upper frame 13 is box-shaped. It is fitted and covered outside the upper part of the outer periphery of the main body, and the lower surface of the upper frame comes into contact with the upper edge of the box-shaped main body and is removably attached.

According to the first aspect, as shown in FIG. 1, the folded-back portion 15a of the inner bag 15 which is folded back outward into the groove 11 formed by the receiving rack 12 on the inner periphery of the box-shaped main body is It is fixed by sandwiching it between the lower surface of the frame and the upper end of the standing wall 12 'on the inner circumference of the receiving shelf. Therefore, the upper surface of the box-shaped main body 10 and the upper surface of the standing wall 12 'are in the same horizontal plane. As a result, the upper edge of the inner bag 15 is fixed and does not fall inside the box-shaped body.

According to the second aspect, as shown in FIGS. 2 and 3, the upper peripheral edge portion 15b of the inner bag 15 which is folded back outward into the groove 11 over the rising wall of the inner circumference of the receiving shelf. Is fixed by an elastic gasket 16 that is compressed and pushed into the groove 11 to prevent the inner bag from falling inside the box-shaped body. Since the box-shaped body is a square prism, it is fixed by using four elastic gaskets along the four sides of the groove 11 in this embodiment. However, two box-shaped bodies facing each other as shown in FIG. 4 are used. An elastic gasket, two L-shaped elastic gaskets facing each other as shown in FIG. 6, or one R-shaped elastic gasket may be used.

In claim 3, as shown in FIGS. 4 and 5, the upper peripheral edge portion 15b of the inner bag 15 which is folded back outward into the groove 11 over the standing wall on the inner circumference of the receiving shelf. The rods 17 for weights, which are made of steel or the like used for concrete work, are dropped into the groove 11 to fix them and prevent the inner bag from falling inside the box-shaped body. Since the box-shaped main body is a square prismatic tube, two U-shaped weight rods facing each other are used in this embodiment. The shape of the weight rod is as shown in FIG. It may be two L-shapes facing each other or a square-shape. The weight bar may have a diameter of about 9 to 13 mm.

In each of the embodiments shown in FIGS. 1, 2, 3 and 4 and 5, it is preferable that the upper end portion 10 of the box-shaped main body is provided with an inwardly inclined surface portion 10 ′ so that the upper frame 13 can be easily covered.

7, 8 and 9 show an embodiment according to claim 4, wherein a box-shaped main body 10 has a receiving rack 12 having a groove 11 formed in an inner periphery of an upper end thereof and an outer periphery fixed to the inner periphery of the main body. A wall is provided, and this outer peripheral wall is projected upward from the upper surface of the main body to form a guide wall 20, and an inwardly sloped portion 20 'is preferably formed at the upper end portion thereof. Then, the inner periphery of the peripheral wall of the upper frame 21 provided with a dust inlet is fitted and covered with the outer periphery of the guide wall 20. As a result, when the upper frame 21 is put on the outer periphery of the guide wall 20, the lower end 21 'of the peripheral wall of the upper frame 21 abuts the upper end 10' of the box-shaped main body, and the outer surface of the peripheral wall of the upper frame and the box-shaped body. It becomes the same surface as the peripheral wall of the main body.

In the embodiment of FIG. 7, as in FIG. 1, the upper surface of the standing wall 12 ′ on the inner circumference of the receiving shelf 12 and the upper surface of the guide wall 20 are flush with each other, and the groove 11 is exposed outward. The folded-back portion 15a of the inner bag 15 which is folded back is fixed between the lower surface of the upper frame 21 and the upper end of the standing wall 12 ', which covers the outer periphery of the guide wall 20, so that the inner bag is inside the box-shaped body. Prevent falling into.

Similar to FIGS. 2 and 3, the embodiment of FIG. 8 has an upper peripheral edge of the inner bag 15 that is folded back outward into the groove 11 over the standing wall on the inner circumference of the receiving shelf. The portion 15b is fixed by an elastic gasket 16 compressed and pressed into the groove 11 to prevent the inner bag from falling inside the box-shaped body.

In the embodiment of FIG. 9, similarly to FIGS. 4 and 5, the upper peripheral edge portion 15b of the inner bag 15 which is folded back outward into the groove 11 over the standing wall on the inner circumference of the receiving shelf. A rod for weight 17 formed of a reinforcing bar or the like used for concrete construction is dropped into the groove 11 and fixed to prevent the inner bag from falling inside the box-shaped body.

The trash can is generally in the shape of a rectangular prism, but each claim of the present invention is also applicable to the cylindrical trash can shown in FIG. 10, in which the upper frames 13 and 21 have a gable roof cross section. The waste inlet 14 may be provided on one or both of the slopes, or may have a one-way roof cross-sectional shape and the waste inlet 14 may be provided on the vertical surface. it can.

[Effect of device]

 According to claim 1, the upper peripheral edge portion of the inner bag folded outward is put in the groove formed by the receiving rack at the upper inner circumference of the box body, and the upper frame is simply put on the box body to fold the inner bag. Part can be fixed. When removing the inner bag together with the dust inside it from the box body and discarding it, all that is required is to remove the upper frame. Therefore, the inner bag can be fixed in the box body and taken out from the box body very easily, and the work can be performed quickly. Further, in claims 2 and 3, the elastic gasket is folded outward and the upper peripheral edge portion of the inner bag, which is inserted into the groove formed by the receiving shelf on the upper inner circumference of the box body, is pushed into the upper groove. Also, fix it with the weight rod that has fallen into the groove. Therefore, after that, the upper frame is mounted over the upper part of the box main body, so that the upper peripheral edge of the bag can be securely fixed. In claim 4, the outer surface of the upper frame of the trash can and the outer surface of the main body of the trash can are on the same surface, and the appearance and appearance of the trash can be improved and the surrounding scenery is not damaged. .
