Abstract

An approach for sterilizing product containers and deactivating microorganisms in such containers employs the container, which, in one embodiment, includes a polyolefin, and which transmits light in a spectrum of from between 180 nm and 300 nm. The container may be coupled to a port through which a product within the container can be withdrawn, or, alternatively, may include a blister that together with a backing material forms a cavity in which a contact lens is contained. A flashlamp system generates high-intensity, short-duration pulses of polychromatic light in a broad spectrum. The pulses of light generated by the flashlamp illuminate the container and thereby deactivate microorganisms within the container. In some embodiments, the container contains a transmissive product that transmits more than about one percent of light at a wavelength of 260 nm. In further embodiments, the high-intensity, short-duration pulses of polychromatic light in a broad spectrum deactivate microorganisms both within the container and within the port. In additional embodiments, the flashlamp advantageously deactivates sufficient microorganisms to achieve a sterility assurance level of at least 10.sup.-6.
