Abstract
Abstract A medical instruments sterilization container (10) includes a housing (12) and a removable lid (14). A removable tray (16) is adapted to hold various medical instruments to be sterilized. The container is formed of a polymer of relatively low thermal conductivity, with a material having a relatively high thermal conductivity being added thereto in order to substantially increase the overall thermal conductivity of the container to absorb radiant heat and rapidly conduct that heat throughout the container to reduce condensate within the container.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
128 words
A medical instrument sterilization container, comprising: a housing for receiving medical instruments for sterilization; a removable lid sealingly fitted to said housing; a tray removably disposed within said housing for supporting the medical instruments; a plurality of apertures defined in a grid pattern in the bottom of said tray to drain condensate therefrom; said tray having a plurality of raised domed portions, each said raised domed portion having a lowered peripheral area with at least two of said apertures, and wherein each of said domed portions slopes toward said lowered peripheral area in order to facilitate drainage of condensate through said apertures and to provide an irregular surface to minimize surface contact of the instruments with said tray and thus prevent condensate from being trapped under the instruments.
Claim 2
Dependent Claim
128 words
A medical instrument sterilization container, comprising: a housing for receiving medical instruments for sterilization; a removable lid sealingly fitted to said housing; a tray removably disposed within said housing for supporting the medical instruments; a plurality of apertures defined in a grid pattern in the bottom of said tray to drain condensate therefrom; said tray having a plurality of raised domed portions, each said raised domed portion having a lowered peripheral area with at least two of said apertures, and wherein each of said domed portions slopes toward said lowered peripheral area in order to facilitate drainage of condensate through said apertures and to provide an irregular surface to minimize surface contact of the instruments with said tray and thus prevent condensate from being trapped under the instruments.
Claim 3
Dependent Claim
27 words
The sterilization container of claim 1 wherein said domed portions are rectangular shaped areas, and wherein said apertures are disposed at the corners of said rectangular areas.
Claim 4
Dependent Claim
29 words
The sterilization container of claim 1 wherein said housing is formed from a polymer of relatively low thermal conductivity having integral therewith a material with a high thermal conductivity.
