ABSTRACT:
A medical waste disposal container has a unitary body structure formed of a substantially flat sheet having a plurality of laminated layers of compact fiberboard, and one or more thin pliable layers of absorbtion resistant plastic material. The laminated sheet material contains a plurality of foldable sheet portions that are scored, wrapped at corners and adhesively joined together to define a bottom, sidewalls and a top of the body structure. The top has an opening, that is closeable by way of a flap formed in the sheet material, for insertion of discarded medical waste. The interior of the container is preferably coated with an absorbtion resistant material to effectively provide a leakproof seal at the intersections of its sidewalls and bottom. Adhesion and additional sealing of the foldable sheet portions is achieved in the course of manufacture by irradiating the laminate sheet material with infrared light, which causes the plastic layer that forms the outer wall surface of the sheet material to become tacky, so that it becomes intimately bonded to an adjacent folded sheet portion to which it is joined, thus securing the wrapped sheet portions together.
