BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contaminant storage container used in a controlled area or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a contaminant storage container used in a controlled area or the like has a container body 1, an upper lid 2 of the container which covers an upper opening of the container body 1, and this upper lid. Two
Is connected to a pedal 3 provided at the bottom of the container body 1, and by stepping on the pedal 3 with a foot, an opening 4 formed in the upper lid 2 is opened, and the opening 4 is opened.
The pedal 3 includes an opening lid 5 that is closed by releasing the pedal 3 in a free state, and a storage bag (not shown) made of synthetic resin that is stored in the container body 1 in a spread state. The upper lid 2 is provided with a handle 6 for removing the upper lid 2 from the container body 1. Then, when the contaminant is put into the container body 1, the pedal 3 is stepped on to open the input port lid 5, the contaminant is input into the storage bag inside the container body 1, and the pedal 3 is released to release the input port lid. Close 5 When taking out a full storage bag from the container body 1, the upper lid 2 of the container body 1 is removed by holding the handle 6, and the mouth of the storage bag is sealed with an adhesive tape. It is pulled up from and taken out.

[0003]

However, the conventional container for storing such a contaminant has the following problems. Since the inlet 4 is narrow, it is difficult to put contaminants in the storage bag inside the container body 1. Step on pedal 3 with your foot and insert opening 4
Although the insertion port lid 5 is opened, the storage bag lacks stability and tends to fall down when the inside of the storage bag is almost empty. Since the container body 1 is simply covered with the upper lid 2 and the charging port 4 is simply opened and closed by the charging port lid 5, the airtightness is poor. When taking out the filled storage bag from the container body 1, first, the upper lid 2 is removed from the container body 1 by holding the handle 6, and the mouth of the storage bag is manually sealed with an adhesive tape. At this time, contaminants may spill out of the storage bag, or the storage bag contacted by the contaminants may be touched by human hands, resulting in contamination or spread of contamination. When the mouth of the storage bag is manually sealed by using an adhesive tape, this work is carried out by wearing rubber gloves, which makes the work difficult. Although it is difficult to obtain a storage bag that fits into the container body 1 and a commercially available standard product is used, the storage efficiency is poor and it is inconvenient to attach and detach the storage bag to and from the container body 1.

An object of the present invention is to provide a contaminant storage container which solves the above problems of the conventional contaminant storage container.

[0005]

The present invention has the following structure in order to achieve the above object. That is, a container body having a stringing slit formed in the upper side wall, and a mouth part having a flange at the upper end of the cylinder part, the cylinder part being inserted into the container body, and the flange being placed at the upper end of the container body. A tubular body, which is removably inserted into the container body, and a string surrounding the outer peripheral upper portion is held on the upper outer peripheral portion, and at least the space between the inner wall surface of the container body and the outer surface of the side wall of the mouth tube body. The upper part is inserted from the string position, and the upper end is sandwiched between the upper end of the side wall of the container body and the flange of the mouth cylinder, and both ends of the string are exposed outside the container body through the string passing slit. A bag, and a lid detachably attached to the upper part of the container body from above the mouth cylinder,
It is assumed that it comprises an input port formed in the lid, an input port lid provided on the input port so as to be openable and closable, and an input port lid opening / closing means connected to the input port lid.

[0006]

According to the above construction, in a state where the lid and the mouth cylinder are removed from the container body, a storage bag which is not contaminated is unfolded and inserted into the container body, and the string is passed through the string passing slit. Take both ends out of the container body, hook the upper end of the storage bag on the upper end of the container body, insert the mouth cylinder into the mouth of the storage bag, put the flange on the top of the container body, and then from above the mouth cylinder. Cover the container body. In this state, the opening is closed by the opening / closing means for the opening.
When the contaminant is stored in the storage bag, the input port opening / closing means is operated to open the input port lid. Therefore, contaminants are introduced through the inlet. In this case, the lid can have a large opening, and the mouth of the storage bag is surely wide because the mouth tube is inserted into the mouth of the storage bag. Contaminants can be put in the storage bag very easily.

When closing the loading port lid, it is closed by operating the loading port lid opening / closing means, and when the storage bag is full, both ends of the string taken out of the string passing slit are pulled to close the loading bag. Squeeze the mouth and bind tightly. Then the lid,
The storage bag can be taken out from the container main body by removing the mouth tube body and the upper body of the main body, grasping the upper end of the storage bag with a gripping member (not shown) or the hand of an operator and pulling it up. Therefore, it is possible to take out the storage bag from the container body without binding the hands of the operator by binding the mouth portion of the storage bag with the string while the lid is kept on.
