[Problems to be solved by the device]

 However, such a conventional contaminant storage container 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. Although the pedal 3 is opened by stepping on the pedal 3 with a foot, when the storage bag is almost empty, it lacks stability and tends to collapse. 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 a full storage bag from the container body 1, first remove the upper lid 2 from the container body 1 with the handle 6 and manually seal the mouth of the storage bag with adhesive tape. At this time, contaminants may spill out of the storage bag, or the storage bag that comes into contact with the contaminants may be touched by humans, resulting in contamination or spread of contamination. When the mouth of the storage bag is manually sealed with adhesive tape, this work is done 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 the market standard product is used, the storage efficiency is poor and it is inconvenient to attach and detach the storage bag to the container body 1.

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