ABSTRACT:
A discarded medical material container comprises a body of sheet material having laminated layers of compact fibrous material and material that is effectively impervious to the passage of fluid. The sheet material is formed into foldable panels that are joined together to define a bottom, sidewalls and a top of the body. The top has a closeable opening for the insertion of discarded material into the container and a closure tab. The top is formed of a first, interior panel of the sheet material having a region that is sectioned to define a plurality of flaps extending inwardly from the contour of the region, so as to define an opening in the first panel of sheet material, and a second, outer panel of sheet material, disposed atop the first panel. The second panel has a cut to define an aperture in the shape of a generally flexible tab overlying the region in the first panel and sized to close the aperture. A slit-score causes each flap to assume a generally downwardly bent condition. The slit-score is adjacent to and set back beneath an edge of the cut through the second panel, so that a portion of the second panel extends over the slit-score, thereby effectively preventing each flap from being bent outwardly through the aperture in the second panel.
