ABSTRACT:
A refrigerated container for receiving, storing, and transporting materials without necessity of personnel contacting the materials after deposit in the container. The container is particularly adapted for use with medical wastes which may contain infectious materials. The container comprises a lower portion and a lid portion. The container lower portion includes an open-topped inner box for holding waste materials, and an open-topped insulated outer box surrounding and spaced apart from the inner box forming an annular space therebetween. The lid is releasably attached to the outer box and has doors for access into the inner box of the container. A refrigeration unit and air circulation fan are attached to the lid, and are in communication with the annular space for cooling the inner box by circularing refrigerated air through the annular space. The lower portion of the container is attached to a lifting member by a hinge and a releasable latch, such that when the latch is engaged, the container may be lifted in a horizontal position. When the latch is disengaged, the container, when lifted, will rotate about the hinge into an inverted position with the open top of the inner box facing downward.
