Abstract: A receptacle for receiving hazardous or infectious waste material which is nonreleasably sealable to prevent spillage or contamination. The receptacle includes a lower, imperforate base container for receiving and holding the waste material. A cover is provided which engages the base container in a nonreleasable fashion. The cover includes a recess having an aperture for receiving the waste material. A hinged lid is attached to the cover and includes a latch for nonreleasably securing the lid over the aperture to retain the waste material in the container. Preferably, the aperture includes a trough having converging, tapered walls to prevent spillage when the aperture is uncovered. The receptacle is made of polypropylene so that the waste material containing receptacle can be easily incinerated.
