Abstract
Abstract A block of, for example, styrofoam for penetration by, and for frictionally holding, disposable hypodermic needles, scalpels and other sharps, is held in a container including a bottom and a sidewall. Pawl-shaped projections are provided adjacent the upper lip of the sidewall. A lid includes complementary pawl-shaped projections adjacent its lower lip for engagement with respective projections on a contaminant neutralizing substance such as BETADINE, or another layer of, for example, wadding, located above or below the styrofoam can be saturated with the contaminant neutralizing substance.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
94 words
A block of material for penetration by, and for frictionally holding, contaminated sharps for disposal, a container for housing the block, the container having a bottom and a sidewall extending from the bottom, a lid for the container, the container including first engagement means and the lid including second engagement means for engaging the first engagement means to reduce the likelihood of disengagement of the lid from the container once the two are engaged, the container sidewall having a first depth and the lid sidewall having a second depth greater than the first depth.
Claim 2
Dependent Claim
94 words
A block of material for penetration by, and for frictionally holding, contaminated sharps for disposal, a container for housing the block, the container having a bottom and a sidewall extending from the bottom, a lid for the container, the container including first engagement means and the lid including second engagement means for engaging the first engagement means to reduce the likelihood of disengagement of the lid from the container once the two are engaged, the container sidewall having a first depth and the lid sidewall having a second depth greater than the first depth.
