Abstract:
A handheld apparatus for sterilizing a desired material retained within a container, the apparatus comprising:a UV generator including: a UV generating bulb, the UV generating bulb being structurally configured for at least partial submersion into the desired material, the UV generating bulb being capable of generating light in the UVC range in the submersed orientation; and a switch capable of selectively activating the UV generating bulb; and means for directly monitoring the desired material, to, in turn, detect an amount of cumulative exposure of light in the UVC range from the UV generator through the desired material wherein the UV generator further includes: a housing associated with the UV generating bulb, the housing having a lip member associated therewith, the lip member extending outwardly and operatively spaced apart from the UV generating bulb; the direct monitoring means further includes: an indicator strip; and a photochromic material disposed thereon, wherein the photochromic material changes in appearance in proportion to at least one of intensity and duration of exposure to light in the UVC range; and wherein the indicator strip is positioned on the lip of the housing so as to be directly exposed to the UV generating bulb.
