Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste storage container, and more particularly to a waste storage container suitable for storing used paper diapers.

[0002]

2. Description of the Related Art At present, a paper diaper used for treating excrements of infants has become the main role of the diaper in place of the conventional cloth diaper. Since disposable diapers are disposable, used disposable diapers must be discarded.

However, since the used paper diaper is accompanied by a bad odor and liquid, it cannot be put in a trash box together with ordinary trash until the trash is collected every 2-3 days. For this reason, it has been practiced to put a used disposable diaper in a plastic bag made of polyethylene sheet and seal the mouth of the plastic bag. However, it is necessary to replace the disposable diaper about 4 to 5 times a day. It is troublesome to open the mouth of a plastic bag and put a used disposable diaper into the bag.

Therefore, there is a demand for a storage container which can easily store a used paper diaper in a plastic bag and can maintain the hermeticity. As a general storage container for such a disposable diaper, there is a bucket-shaped container with a lid. A bag is covered with a plastic bag, and the outside of the bag is covered with a lid with the opening edge of the bag folded back to store a used paper diaper.

In addition, after storing a long plastic bag and putting a used paper diaper into the plastic bag, the plastic bag is mechanically twisted, and both sides of each paper diaper are twisted and squeezed, and then sealed inside the plastic bag. There is a storage container to do.

[0006]

However, a bucket-shaped storage container with a lid is inexpensive, but the lid has insufficient sealing performance. In particular, when the plastic bag is used by covering the inside of the bucket, the plastic bag is interposed between the lid and the bucket, so that the hermeticity is impaired and the odor is not sufficiently sealed. Moreover,
Since it looks like a bucket, it does not look good and cannot be used as furniture in a room.

A mechanical storage container for storing a paper diaper by twisting it in a long plastic bag requires a mechanical device, which increases the size and cost of the container. Moreover, there is a risk of breakdown.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a waste storage container which can store a used disposable diaper by a simple operation, has excellent sealing property, and can be provided at a low cost. To do.

[0009]

In order to achieve the above object, the waste storage container according to claim 1 has a storage container body having an input port communicating with the inside thereof, a peripheral wall of the input port and / or the vicinity thereof. And a packing member having a mounting seal part to be mounted by crimping and a ring-shaped opening seal part formed integrally with the mounting seal part, and closes the opening seal part by closely contacting the opening seal part. And a lid member.

Such a waste storage container has a structure in which one packing member performs the close contact of the plastic bag and the sealing by the lid member. That is, in this waste storage container, a plastic bag is put in the main body of the storage container, and the packing member is attached to the peripheral wall of the input port in a state where the opening of the poly bag is pulled out from the input port of the storage container body and folded back. Attach and use. By interposing a plastic bag between the peripheral wall of the charging port and the packing member, and crimping the mounting seal part of the packing member to the peripheral wall of the charging port, the poly bag adheres to the mounting seal part of the packing member, The opening serves as an opening seal portion of the packing member. By closing the opening sealing portion of the packing member with the lid member, the opening portion of the plastic bag can be airtightly closed. Normally, the opening of the plastic bag is hermetically closed by covering the opening sealing portion of the packing member with the lid member. When throwing in a used disposable diaper, separate the lid member from the packing member, put it in the poly bag inside the storage container through the opening seal part of the packing member, and after closing, close the lid bag to seal the poly bag. The state is obtained. Since the configuration is such that a packing member is added to an ordinary storage container with a lid, it can be provided at low cost. Therefore, such a waste storage container can store a used disposable diaper by a simple operation, has an excellent sealing property, and can be provided at a low cost.

A waste storage container according to a second aspect is the waste storage container according to the first aspect, in which the mounting seal portion of the packing member is disposed slightly inside the peripheral wall of the charging port. -Shaped body, an outwardly projecting flange portion integrally formed on the upper end edge of the short-axis tubular body, and an outer surface of the short-axis tubular body projecting outward over the entire circumferential direction thereof. And a ring-shaped fin portion that is integrally formed and is bent by the peripheral wall of the charging port to press the peripheral wall.

In this packing member, when the short-axis tubular body is inserted while the plastic bag is passed through the peripheral wall of the charging port of the storage container main body, the fin portion is pushed by the peripheral wall of the charging port to be bent to bend the charging port peripheral wall. Can be pressed for pressure bonding. At that time,
The flange portion of the packing member functions as an insertion stop member, and the packing member can be reliably attached to the charging port.

A waste storage container according to a third aspect of the present invention is the waste storage container according to the first aspect, wherein the storage container body is constructed by assembling parts including a bottom plate, side plates and a top plate.

Such a waste storage container is an assembly type,
Since it can be disassembled for transportation, transportation costs can be reduced, and storage after use is compact and convenient.

A waste container according to a fourth aspect of the present invention is the waste container according to the third aspect of the invention, in which the side plates are fixed to each other by a shaft that is stretched between the facing side plates.

Such a waste storage container is strong in strength because the side plates constituting the container body are fixed by the shaft.

A method of using such a waste storage container 1 will be described. The capacity of the storage container body 20 is, for example, 2
It is enough to store a 0 liter commercially available plastic bag inside. As shown in FIG. 6, the plastic bag 50 indicated by the broken line is stored in the storage container main body 20, and the opening end edge of the plastic bag 50 is placed in the insertion port 261 and folded back to the outside. In this state, the packing member 28 is fitted into the cylindrical body 262 of the charging port 261. As shown in FIG. 5, the outer diameter of the short-axis tubular body 284 of the packing member 28 is slightly smaller than the inner diameter of the tubular inner wall 265 of the tubular body 262 of the charging port 261, and the first fin portion 286 can be bent thinly. Therefore, the short-axis tubular body 284 of the packing member 28 is inserted along the tubular inner wall 265 of the loading port 261 until the lower end of the flange portion 285 abuts the upper end edge of the tubular body 262 of the loading port 261. As a result, the first fin portion 286 is inserted into the insertion port 261.
The cylindrical inner wall 265 is bent upward, and the first fin portion 286 crimps the cylindrical inner wall 265 of the charging port 261 by being bent. Therefore, the first fin portion 286 presses the plastic bag 50, which is interposed between the cylindrical inner wall 265 of the input port 261 and the first fin portion 286, against the cylindrical inner wall 265 of the input port 261 and the first fin portion. The tip portion of 286 and the inner surface of the plastic bag 50 are airtightly adhered. As a result, the opening of the plastic bag 50 stored in the storage container body 20 becomes the packing member 28.

Further, the first fin portion 286 is provided with an input port 261.
Since it is bent upward by the cylindrical inner wall 265 and functions as a kind of ratchet with respect to the plastic bag 50, there is a strong resistance against the plastic bag 50 falling into the storage container body 20. Therefore, it is prevented that the opening side of the plastic bag 50 protruding from the input port 261 is pulled downward by the weight of the plastic bag in the storage container body 20 and the opening of the plastic bag 50 is drawn into the storage container body. can do. As a result, the plastic bag 50 having a capacity much smaller than that of the storage container body 20 is used, and
Since the packing member 28 firmly holds the plastic bag 50 in the input port 261 even when it is hung down to 1 and is prevented from being drawn into the storage container body 20, the plastic bag 50 having a small capacity is also used. Can be used.

To store the disposable diaper, the opening / closing lid 40, which is normally closed, is opened by operating the lock mechanism 271, and the used disposable diaper is loaded into the storage container body 20 through the loading port 261 and then the opening / closing lid 40 is closed. Do by operation.
When the opening / closing lid 40 is closed, the disc portion 421 of the lid member 42 pushes down the second fin portion 287 of the packing member 28 by about several mm to bend the second fin portion 287, and the second fin portion 287 makes the disc member 42 of the lid member 42. The part 421 is crimped, and the disk part 4
21 airtightly adheres. As a result, the opening of the plastic bag 50 is hermetically closed, and the odor inside the plastic bag 50 is sealed.

When the plastic bag containing the used paper diaper is taken out from the container body 20, the finger hook 281 (see FIG. 3) of the packing member 28 is put on the finger and the packing member 28 is removed from the charging port 261. . Next, the top plate 26 is removed from the upper frame member 27 by releasing the engaging member 263, and the plastic bag in the storage container main body 20 is taken out to discard the plastic bag in which the used paper diaper is stored. You can

As described above, the waste storage box 1 of this embodiment
Is a structure in which one packing member 28 performs close contact with the plastic bag 50 and close contact with the lid member 42. Therefore, the number of parts is small and it can be provided at low cost. Further, since opening and sealing of the set plastic bag 50 can be performed by a simple operation of opening and closing the opening / closing lid 40, it is easy to store a used disposable diaper. In addition, the dust bag is sealed by pressing the first fin portion 286 and pressing the second fin portion 28.
7 is pushed down by the disc portion 421 of the lid member 42, so that the operation is surely performed, so that the odor sealing property is good.

Further, since it is of an assembly type and the transportation cost can be reduced, it can be provided at a low cost. Further, when an infant grows up and does not need to use a diaper, it can be disassembled and stored, so that the volume during storage can be reduced.

Furthermore, since MDF is used for the side plates 22 to 25, the side plates 22 to 25 have a high-class feeling and do not feel uncomfortable even if they are always placed indoors.

The waste container of the present invention is not limited to the above-mentioned embodiment. For example, the storage container main body may be formed by integral molding of resin, although it is an assembly type in the above-described embodiment. Further, although the opening seal portion of the packing member is a trumpet-shaped fin, the shape is not limited and may be, for example, a bellows shape. Further, since the waste storage container of the present invention is also hygienic, it can be used not only for storing used paper diapers but also for storing waste in hospitals, for example, and there is no limitation on the use.

Although MDF is used as the side plate,
The side plate may be made of a plastic plate. In this case, since the weight of the storage container main body is reduced, it is possible to fix the side plate and the bottom plate, and the side plate and the upper frame member without using the metal shaft.

Although the charging port is formed on the top plate, it may be formed on the side plate, for example.

Further, although the packing member presses the peripheral wall of the charging port by the mounting seal portion, the packing member may be pressed not only on the peripheral wall but also in the vicinity of the charging port.
For example, the mounting seal portion may be formed in a U-shaped cross section so as to wrap around the edge of the charging port.
