A sterilization container for sterilizing, storing and transporting instruments is formed of a liquid crystal polymer, such as a wholly aromatic polyester. The container is strong yet has thin walls so that condensation is minimized. Suitable polymers include wholly aromatic polyesters such as: polybenzoate-naphthalate; polybenzoate-terephthalate-bisphenol-isophthalate; polybenzoate-terephthalate-ethylene glycol; and polynaphthalate-amino terephthalate.

1. In a sterilization container for sterilizing instruments, comprising: a wall enclosing the container; means for holding a medical instrument against movement within the container; and at least one opening into the container, through an upper surface thereof, for admitting sterilizing gases; and at least one drainage aperture through a lower surface of the container for draining liquid from the container; the improvement comprising the wall being formed of a thermoplastic liquid crystal polymer whereby the wall resists chemical attack from hydrogen peroxide, and ethylene oxide, the wall does not unduly interfere with any electromagnetic fields, and the wall resists attack from elevated temperatures. 2. A sterilization container according to claim 1 wherein the thermoplastic liquid crystal polymer comprises a wholly aromatic polyester. 3. A sterilization container according to claim 1 wherein the liquid crystal polymer is reinforced with a filler. 4. A sterilization container according to claim 3 wherein the filler comprises glass or mineral fibers. 5. A method of sterilizing an instrument comprising the steps of: placing the instrument into a sterilization container which comprises a wall formed of a thermoplastic liquid crystal polymer enclosing the container, a first opening through an upper part of the wall for admitting sterilizing gases, a second opening through a lower portion thereof for draining liquid from the container, and a holding means for holding the instrument within the container; holding the instrument in a fixed location within the container with the holding means; and admitting a hydrogen peroxide gas into the container through the first opening and into contact with the instrument. 6. A method according to claim 5 and further comprising the step of applying an electromagnetic field to drive the hydrogen peroxide into the plasma phase. 7. A method according to claim 5 and further comprising the steps of removing the instrument from the container after contacting it with the hydrogen peroxide and then repeating the steps of placing the instrument into the container, holding the instrument in a fixed location and admitting hydrogen peroxide gas into the container. 8. A method according to claim 5 and further comprising the step of filtering gaseous material entering the container through a filter impermeable to microorganisms. 9. A method according to claim 5 wherein the filter comprises a wrappable material and the step of filtering includes the step of wrapping the container with the filter. 10. A method according to claim 5 wherein the thermoplastic liquid crystal polymer is a wholly aromatic polyester.
