Title: Syringe with actinic radiation protection

Abstract: A syringe-type dispenser for medication and like applications, comprising a housing with a piston and an outlet seal at its opposite ends, containing a liquid medication or other liquid subject to deterioration from exposure to actinic light; the syringe housing is clear and transparent (preferably clear glass) but is covered with a thin resin film which inhibits the transmission of actinic light while passing other light in the visible spectrum. At least part of the protective film is readily removable to afford improved inspection of the syringe contents at the time of dispensation.
