BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste container, and more particularly to a waste container configured to store a waste bag.

[0002]

2. Description of the Related Art A trash container used in recent years does not directly put trash therein, but generally contains a trash bag so that the trash can enter therein. Since this dust bag is generally formed of a thin synthetic resin film, various measures must be taken to fix the dust bag in the dust container in an expanded state.

As such a conventional garbage container, for example, as shown in Japanese Utility Model Publication No. 38-7644 and FIG. 7, a frame edge 41 separate from the lid 30 and the container body 40 is used. The frame bag 41 is used to fix the dust bag 50 stored in the container body 40. Further, in this conventional garbage container, the notch 42 is formed in a part of the frame edge 41, so that the frame edge 41
A part of the elastic frame edge 41 has elasticity, and a projection 43 is formed on the inner surface of the elastic frame edge 41.

However, in the conventional garbage container shown in FIG. 7, since the notch 42 is opened at the lower end edge of the frame edge 41, the elasticity of the frame edge 41 supporting the projection 43 is extremely high. The frame edge 41 supporting the protrusion 43 is easily broken, depending on how it is used.
Alternatively, the garbage bag 50 may easily come off.

Therefore, for example, Japanese Utility Model Publication No. 47-21597.
As shown in the publication and FIG.
While forming two annular protrusions 43, 44 on the upper edge of
Dust formed by forming an annular groove 45 to be fitted into the projection 2 on the lower surface of an annular frame member 41 prepared separately, and pivoting the end of the gripping rod 46 at a position facing the inner circumference of the frame member 41. A "vessel" was proposed. Although this dust container is considered to be tough without any unstable portion like the dust container 40 shown in FIG. 7, the two annular projections 43 and 44 are made of, for example, a synthetic resin material. It is very difficult to form the main body 40 integrally with the main body 40.
It is practically impossible to form the bulge 47 for stopping the swelling. That is, such a bulge 47 serves as an undercut portion when it is molded by a mold, but in order to form such an undercut portion,
Not only does the mold itself become very complicated, but a mold for the bulge 47 having the shape shown in FIG. 7 cannot be formed. Not only that, but also the two annular projections 43, 44
Will form a groove having a U-shaped cross section, but such a groove cannot hold the annular frame member 41.

[0006] Therefore, the inventors of the present invention have made earnest studies on how to make a dust container that can reliably hold the dust bag and is easy to manufacture, and as a result,
The present invention has been completed.

[0007]

In the waste container constructed as described above, when the respective members are integrally molded using, for example, a synthetic resin as a material, the manufacture thereof is extremely easy. That is, in the container body 10, first, the engaging portions 11 as shown in FIG. 4, for example, may be formed at the portions of the upper inner wall surface facing each other. Since it does not need to be formed on the entire upper part of the inner wall surface of the container, the manufacturing of the container body 10 is very easy. In addition, the support frame 2
No. 0 can also be formed as a completely different member from the container body 10 and the lid 30, and an opening 23 is formed at the intersection of the flange portion 22 and the leg piece portion 21, and the leg piece portion is formed from both sides. Since it is sufficient to form the notch 24 up to the middle of 21, the manufacturing thereof is very easy. In particular, the opening 23 is effective as a portion for performing die cutting for each notch 24, so that the shape of the die is not complicated, and the die formation is facilitated and the support frame 20 is formed. Simultaneous manufacture is achieved at the same time. Further, since the engaging projection 26 of the tongue piece portion 25 is the outer surface of the leg piece portion 21, the molding of the engaging projection 26 is very easy.

In particular, the engaging portion 11 of the container body 10 is recessed from the inner surface of the container body 10 as shown in FIG. 4, and the right side of the engaging portion 11 in the drawing is the container body. Since it is inside 10, there is sufficient space for retracting the mold, and the mold can be easily removed. Further, even if the mold is not retracted, the engaging portion 11 need only be partially formed as shown in FIG. 1 and is not so deep. If you take out the mold from the mold by using the flexibility, this engaging part 1
The container body 10 having 1 is easily formed.
On the other hand, with respect to the support frame 20 as well, by making the end surface on the flange portion 22 side forming the opening 23 face the end portion of the engagement projection 26 on the upper side in the drawing, as shown in FIGS. 3 and 6. It is possible to easily form the opening 23 and the engaging projection 26 by the mold.

In order to use this garbage container, the following procedure should be performed. That is, first, the dust bag 50 is put in the container body 10, the opening of the dust bag 50 is expanded to the outside of the vertical flange 13 of the container body 10, and the opening edge of the dust bag 50 is placed on the outer surface of the vertical flange 13. To be located. Then, if the leg pieces 21 of the support frame 20 are pushed into the vertical flange 13 in this state, the dust bag 50 is fixed to the upper end side of the container body 10 by the support frame 20 as shown in FIG. Is done.

That is, when the leg piece portion 21 of the support frame 20 is pushed into the dust bag 50, the tongue piece portion 25, which can be bent with respect to the leg piece portion 21 by the opening 23 and the pair of notches 24, When the engaging projection 26 formed on this bends while contacting the inner surface of the container body 10 and the engaging projection 26 engages with the engaging portion 11 of the container body 10, as shown in FIG.
It returns to the natural state with the dust bag 50 sandwiched. At this time, as shown in FIG. 5, the garbage bag 5
The open end of No. 0 is pressed by the horizontal flange 12 of the container body 10 and the flange portion 22 of the support frame body 20, and as described above, is clamped between the leg piece portion 21 of the flange portion 22 and the inner surface of the container body 10. In particular, each tongue piece 2
The dust bag 50 is firmly sandwiched between the engagement protrusion 26 of No. 5 and the engagement portion 11 on the container body 10 side. Since the support frame 20 itself covers the entire circumference of the upper end opening of the container body 10, the opening end portion of the dust bag 50 is clamped over the whole, and the support frame body 20 is attached to the waste container. The dust bag 50 is reliably supported.

In this case, the engaging portion 11 on the container body 10 side
Are formed so as to face each other, and the engaging projections 26 are formed on the support frame 20 side so as to correspond to the engaging portions 11, respectively.
The holding of the dust bag 50 by the engaging projections 26 and the engaging projections 26 is performed with good balance. In other words, the holding of the dust bag 50 by the engaging portion 11 and the engaging protrusion 26 is performed uniformly with respect to the container body 10. As a result, when the lid 30 is opened and closed, the support frame 20 not only firmly holds the dust bag 50 on the container body 10 side, but also when the lid 30 is opened, the support frame 20 is easily removed from the container body 10. It does not come off. Since the container body 10 shown in the embodiment has a quadrangular shape, it is easy to make the engaging projections 26 face each engaging portion 11, but when the container body 10 has a round shape. For example, the positioning protrusion of the support frame 20 with respect to the container body 10 may be formed on the container body 10 or the support frame 20.

Further, in order to take out the full dust bag 50 together with dust, contrary to the above, first, the support frame 2
It is only necessary to remove 0 from the container body 10. As a result, the open end of the dust bag 50 is completely free,
The dust bag 50 can be easily taken out of the container body 10.
