Abstract:
A method of simultaneously forming detectable non-deposited markings on a discrete consumable article and on packaging material therefor, said discrete consumable article being intended for consumption by a living being for therapeutic purposes, comprising the steps of:providing a marking window in said packaging material; including an amount of radiation sensitive material in both said marking window and said discrete consumable article, said amount of radiation sensitive material being sufficient to permit an ultraviolet laser energy to simultaneously form said detectable non-deposited markings on both said marking window and said discrete consumable article, said marking window being sufficiently transparent to said ultraviolet laser energy to permit said ultraviolet laser energy to pass therethrough and form said detectable non-deposited markings on said discrete consumable article; providing a source of said ultraviolet laser energy; interposing said marking window between said source and said discrete consumable article; simultaneously exposing said discrete consumable article and said marking window to said ultraviolet laser energy in a predefined pattern to form said detectable non-deposited marking in said predefined pattern on both said marking window and said discrete consumable article, said step of simultaneously exposing to said ultraviolet laser energy being insufficient to cause visible physical degradation to said marking window and said discrete consumable article when viewed at no more than about 5 power magnification.
