However, in the above-mentioned conventional garbage container, the elastic piece (11) provided on the inner case (1) is bent inward, so that the hook (1a) Since the projection (2a) is locked or unlocked, if the elastic return ability of the elastic piece (11) deteriorates due to long-term use, the hook (1a) and the projection (2a) ) Is not easily locked.

In order to bend the elastic piece (11), a plurality of slits (1b) are formed at the upper end of the inner case (1), so that the inner case (1) has a plurality of slits. There is also an inconvenience that the folded portion of the bag is easily damaged by being caught in the slit (1b). The invention according to claim 1 is composed of a bottomed inner case in which a plastic bag for storing garbage is set, and an outer case that covers the entire inner case from above and has an outer lid. Garbage container configured to be connected to
It is an object of the present invention to provide a dust container which can be reliably locked when the outer case is fitted to the inner case, and in which the lock portion is not easily damaged.

A second object of the present invention is to provide a more reliable locking property in addition to the object of the first aspect of the present invention. The invention described in claim 3 is the invention according to claim 1.
Another object of the present invention is to ensure that the locked state and the unlocked state of the outer case and the inner case can be reliably maintained.

According to a fourth aspect of the present invention, in addition to the objects of the first to third aspects, it is possible to easily determine the directions of the outer case and the outer case when fitting the outer case to the inner case. Make it an issue.

[0010]

In order to solve the above-mentioned problems, the invention according to claim 1 of the present invention is directed to a method in which a hook portion is formed on mutually facing side walls of the inner case, and A lock piece is rotatably provided at a position on the side wall facing the hook portion, and the lock piece is configured to engage and disengage from the hook portion by a reciprocating rotation operation. "

The lock piece is provided separately from the outer case, and is rotatably supported by a side wall of the outer case. Then, in a state where the outer case is externally fitted from above the inner case, by rotating the lock piece to one side, the lock piece is engaged with the hook portion to be in a locked state, and the lock piece is locked. By turning to the other direction in the opposite direction to the above, the engagement is released.

In order to replace the plastic bag set in the inner case, the lock piece is rotated to the other side to release the engagement with the hook. Thereby, the lock piece is in the unlocked state, and the outer case can be pulled upward from the inner case. After the replacement of the plastic bag, the outer case is again fitted to the inner case such that the lock piece faces the hook portion, and in this state, the lock piece is rotated to the one. Then, as described above, the lock piece engages with the hook formed on the side wall of the inner case and is locked, so that the outer case is prevented from falling out of the inner case.

According to a second aspect of the present invention, in the configuration of the first aspect, "a convex portion is provided at an action point portion of the lock piece, and the convex portion can be fitted into the side wall of the inner case. Forming an opening, and the upper side of the opening as the hook portion. "
It is characterized by the following. In this device, when the lock piece is rotated to the one side and the protrusion is fitted into the opening provided in the inner case, the upward movement of the outer case with respect to the inner case causes the protrusion to move toward the inner case. The locked state is prevented by engagement with the hook portion corresponding to the upper side of the opening.
As a result, the outer case and the inner case are fixed in a retaining state. Then, when the lock piece is rotated to the other side, the convex portion escapes from the opening, disengages the engagement, and enters a lock release state.

The invention described in claim 3 is the first or second invention.
The invention according to the above aspect is characterized in that "lock piece attitude maintaining means for maintaining the attitude of the lock piece in the locked state and the unlocked state is provided". Here, as the lock piece attitude maintaining means, for example, a lock piece for preventing rotation of the lock piece by abutting on the side wall of the outer case in a locked state and an unlocked state of the lock piece. It is possible to adopt a configuration in which the projection is provided in the vicinity of the rotation fulcrum of the lock piece.

For example, a mounting opening is formed in a side wall of the outer case, and a rotation fulcrum of the lock piece is located on a surface above the mounting opening. Then, a protrusion is provided near the rotation fulcrum portion of the lock piece,
It is provided so as to protrude in the same direction as the convex portion. In this case, in the locked state, the rotation fulcrum is located at the upper end of the lock piece, and the protrusion projects inward from the mounting opening of the outer case and engages with the hook of the inner case. Combine. At this time, the protrusion contacts the upper surface of the mounting opening of the outer case above the rotation fulcrum of the lock piece, and is opposite to the protrusion with respect to the rotation fulcrum. At the lower end of the lock piece is prevented from turning upward (outward). Then, by forcibly rotating the lower end portion of the lock piece so as to draw an arc upward, the protrusion is lowered along the surface, and the locked state can be released. In this unlocked state, the protrusion comes into contact with the surface below the pivot point,
Inadvertent rotation of the lock piece below the lower end (toward the inner case) is prevented.

As described above, the projections function as stoppers for preventing the lock pieces from inadvertently rotating in the locked state and the unlocked state, and for maintaining the respective postures. The invention according to claim 4 is the invention according to claim 1.
3. The configuration of the invention described in 3 to 3 above, "The cross-sectional shape of each of the inner case and the outer case is a shape in which the horizontal length and the vertical length are set to different lengths, and the shapes are substantially similar to each other. The relationship was made. "

According to the above configuration, the orientation of the outer case over the inner case is naturally determined. Therefore, by providing the lock pieces and the hooks at respective positions corresponding to each of the cross sections of the outer case and the inner case, the outer case is fitted to the inner case at the same time as the lock. The piece will face the hook.

[0018]

As described above, the invention according to claim 1 of the present invention is provided separately from the outer case and separately from the operation of fitting the outer case to the inner case. Since the lock piece is engaged with the hook of the inner case by reciprocatingly rotating the lock piece rotatably supported on the side wall of the outer case, the lock state is released from the lock state. In addition, there is a response during the reverse operation, and the reliability of each operation is improved.

Further, since no slit or the like is formed at the open end of the inner case, it is hardly damaged even when used for a long period of time, and the lock property of the lock piece does not deteriorate. Furthermore, the inconvenience that the folded portion of the plastic bag set in the inner case is caught by the slit and damaged can be prevented. According to a second aspect of the present invention, in addition to the effect of the first aspect, when the projection of the lock piece fits into an opening provided in a side wall of the inner case, it engages with a hook of the inner case. With this configuration, the lock piece and the hook portion can be deeply engaged. Thereby, the reliability of the locked state is further improved.

According to a third aspect of the present invention, in addition to the effects of the first or second aspect of the present invention, for example, a protrusion for preventing the lock piece from rotating is provided as the lock piece attitude maintaining means. Since the posture of the lock piece in the locked state and the unlocked state can be maintained, there is no inadvertent transition from the locked state to the unlocked state or vice versa. Therefore, when the outer case is removed from the inner case, there is an additional effect that there is no inconvenience that the lock piece is carelessly hooked on the hook portion and is difficult to remove.

According to a fourth aspect of the present invention, in addition to the effects of the first to third aspects, when the outer case is externally fitted to the inner case, the orientation thereof can be accurately and easily positioned. As a result, the operability of the lock piece is improved.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described together with the illustrated example. FIG. 1 is a partially cutaway perspective view showing a state in which an outer case (2) constituting a dust container according to an embodiment of the present invention is removed from an inner case (1). The outer case (2) is a cylindrical body made of a synthetic resin and having an elliptical cross section. The upper open end of the outer case (2) is rotatably supported by an outer lid (4) and can be opened and closed. At both ends of the outer case (2) on the major diameter side, there are provided recesses (21) which are open upward and laterally outward and have a mounting opening (20) formed at the center. The first surface (20a) on the upper side of the opening (20) is set to be more inward than the second surface (20b) on the lower side. Then, a pair of third third members forming both side surfaces of the concave portion (21) is formed.
At the upper end of the surface (20c), a groove (20d) for pivotally supporting a shaft portion of a lock piece (5) described later is formed in an upwardly open state.

The lock piece (5) has a pivot fulcrum (51) at the upper end, and the groove (20) extends from both sides of the pivot fulcrum (51).
The support shaft part (51a) fitted into d) protrudes. While supporting the spindle (51a) in the groove (20d),
At a position corresponding to the mounting opening (20) in a state where (5) is hung down, the outer case passes through the mounting opening (20).
An engaging projection (52) projecting inward from (2) is formed.
Near the tip of the rotation fulcrum (51), a protrusion (5
1b) project in the same direction as the engaging projection (52). At the lower end of the lock piece (5), a projecting portion (53) projecting outwardly of the outer case (2) in a quarter arc shape is formed.

The diameter of the support shaft (51a) is set to a dimensional relationship substantially corresponding to the width of the groove (20d), and the support shaft (51a) fitted into the groove (20d) from above in a closely fitted state. 51a) is difficult to inadvertently escape upward. Further, in the engagement posture of the lock piece (5) in which the engagement projection (52) is projected inward from the mounting opening (20), the lock piece (5) is inserted into the recess (21). It is accommodated in a state where a gap portion (50) is provided below the overhang portion (53), and the projection (51b) has a dimensional relationship such that the projection (51b) contacts the first surface (20a). Next, the inner case (1) housed inside the outer case (2) will be described.

The inner case (1) is also made of the same synthetic resin as the outer case (2). As shown in FIG. 1, the bottom case having a similar cross-sectional shape smaller than the cross-sectional shape of the outer case (2) is used. And a flange (13) protrudes outward at the upper end. The height from the bottom of the inner case (1) to the top surface of the flange (13) is from the lower end of the outer case (2) to the first surface (20a).
The height is approximately equal to the height to the lower end of the inner case, and the mutual dimensions are set so that a sufficient gap is created between the outer wall of the inner case (1) and the inner wall of the outer case (2). deep. (See Fig. 2)
An opening (10) is formed at both ends on the major diameter side of the inner case (1) and at positions below the flange (13),
A part of the flange (13) located above the opening (10) is an inclined surface (14) inclined obliquely downward toward the outside. The lower end of the inclined surface (14) is engaged with the engagement projection of the lock piece (5).
(52) becomes the engaging portion (12) to be engaged.

To use this, first, the inner case
(1) Set a plastic bag (not shown) for storing garbage in
Put the outer case (2) over the inner case (1). Since the inner case (1) and the outer case (2) have similar elliptical shapes, when the long diameters are made to correspond to each other, the lock piece (5) is formed on the inclined surface (14) of the inner case (1). It can be positioned to be located above. At this time, lock piece
Even when (5) remains in the engaging position, the tip of the engaging projection (52) of the lock piece (5) moves on the inclined surface (14) as the outer case (2) descends. You will slide down,
The lower end of the lock piece (5) is forcibly rotated outward. When the outer case (2) covers the entire inner case (1), the engaging projection (52) is located below the inclined surface (14) and faces the opening (10). . In this state, the lock piece (5) is rotated toward the inner case (1).

Then, as shown in FIG. 2, the lock piece (5)
The engaging projection (52) of the inner case (1) is inserted into the opening (10) of the inner case (1) through the mounting opening (20) of the outer case (2), and is engaged with the lower end of the hook (12). Will be stopped. At this time, the projection (51b) provided on the pivot (51) of the lock piece (5)
Abuts against the first surface (20a) above the mounting opening (20) above the pivot point (51), and the lower end of the projecting portion (53) of the lock piece (5) and the A gap (50) is formed between the lower ends of the two surfaces (20b) to allow a fingertip to enter. In this state, the projection (51b) functions as a stopper that prevents the lock piece (5) from rotating outward,
The above posture of the lock piece (5) is maintained. Therefore, the outer case (2) is securely fixed to the inner case (1) in a retaining state, and the inner case (1) and the outer case (2) are integrated.

Next, the operation of separating the outer case (2) from the inner case (1) when replacing the plastic bag will be described. Below the lock piece (5), the gap (5
(0) is formed, insert the fingertip into the gap (50) to support the lower end of the protruding portion (53) of the lock piece (5), and draw the lock piece (5) so as to draw an upward arc. Is forcibly rotated. Since the inner case (1) and the outer case (2) are made of synthetic resin, by forcibly rotating the protrusion (51b) of the lock piece (5), the first surface (20a ) Is slid down along the first surface (20a) while elastically deforming it slightly inward. Then, as shown in FIG. 3, the projection (51b) functions as a stopper that maintains the lock piece (5) in a substantially horizontal posture when it reaches below the rotation fulcrum (51).

As a result, the lock piece (5) remains in the horizontal position, so that the side of the projection (53) does not inadvertently rotate downward. Therefore, when the outer case (2) is pulled up in this posture, the outer case (2) can be separated from the inner case (1). ) Does not inadvertently catch on the hooking part (12), and there is no inconvenience that the separation work takes time.

In this embodiment, the cross-sectional shapes of the inner case (1) and the outer case (2) are similar to the elliptical shape, but the outer case (2) is connected to the inner case (1). A rectangular shape or any other shape may be used as long as the shape is easy to position when fitted.
