A receptacle for a contaminant comprises a container and a rotatable lid which can rotate about an axis. The lid includes a cylinder and a slider which can reciprocate in the cylinder. And the slider is disposed in a compartment of the closed end of a flexible casing. First, a contaminant is put into the cylinder, then the lid can rotate about an axis, the slider moves down in the cylinder under gravity to push the contaminant into the container. The flexible casing is disposed in the cylinder, and an elastic ring is arranged along the opening of the flexible casing. The advantage of the receptacle is in that: used conveniently and completely cleared. |
