Abstract

A container for disposing of hazardous wastes including an inner receptacle adapted to receive and contain the hazardous wastes or etiological agents and an impact resistent outer container with the inner receptacle disposed within the outer container. The container further includes a fluid barrier located between the inner receptacle and the outer container. The fluid barrier acts as an intermediate containment to minimize fluid from passing from the inner receptacle to the outer container in the event the inner receptacle is ruptured.

Claims

1. A container for disposing of hazardous waste, said container comprising:

an inner receptacle adapted to receive and contain hazardous waste, said inner receptacle including a body having a closed end and an open end disposed opposite said closed end, said open end of said body defining an upper rim, said body further including threads disposed about a portion of its circumference at its open end and a threadably removable cap adapted to sealingly close said open end of said body, a gasket disposed between said rim and said threaded cap to form a seal therebetween and prevent leakage from said inner receptacle;

an impact resistant outer container, said inner receptacle being disposed within said outer container, said outer container including a sleeve with at least one open end and having at least one removable end cap which defines a socket and which is disposed over said open end of said sleeve to completely enclose said inner receptacle; and

a fluid barrier disposed between said inner receptacle and said outer container, said fluid barrier including a polyethylene liner having an open end, said inner receptacle adapted to be disposed within said liner with said liner being sealable at its open end, said fluid barrier further including an absorbent shield disposed about at least a portion of said inner receptacle and between said liner and said inner receptacle for absorbing any liquid present between said inner container and said liner, said fluid barrier preventing any fluid from passing from said inner receptacle to said outer container.

2. A container as set forth in claim 1 further characterized by said inner receptacle and outer container disposed within a cardboard box which may be transported from one point to another through the mail.

3. A container as set forth in claim 1 further characterized by said impact resistent outer container including an open ended cylinder with a pair of end caps removably disposed on either end of said cylinder to completely enclose said inner receptacle and said fluid barrier.

4. A container as set forth in claim 3 further characterized by said open ended cylinder being made of kraft paper, said end caps being made of polyethylene foam bead.

5. A container as set forth in claim 4 further characterized by said body being cylindrical and including a pair of flanges disposed about the cylindrical periphery thereof and spaced relative to one another for strengthening said body of said receptacle.

6. A container as set forth in claim 5 further characterized by said absorbent shield being cylindrical in shape and disposed about the circumference of said body of said inner receptacle between said pair of flanges, said shield being made of cotton type fiber and coated with a durable facing.

7. A container as set forth in claim 6 further characterized by including a conically shaped sealing member disposed within the opening of said body of said inner receptacle and including an aperture which allows medical waste to enter said inner receptacle but otherwise limits access to the interior of said inner receptacle.

8. A container as set forth in claim 7 further characterized by said sealing member being made of low density polyethylene, said aperture in said sealing member including a shaped opening centrally located on said sealing member and a plurality of slots extending radially outward from said keyhole which allows said sealing member to flex and accept waste of varying sizes.
