  • Patent number: 5236101
    Abstract: The invention relates to a tamper-indicating radiation-proof film container. The container comprises a canister having an opening defined therein, and a closure member having a peripheral canister-engaging portion. A tamper-indicating seal is located between adjacent contact surfaces of the canister-engaging portion and the canister, and the closure member is translucent for enabling the condition of the tamper-indicating seal to be viewed. Shielding means are provided for shielding the contents of the container from ionising radiation. The shielding means may be in the form of an intermediate lead layer and an inner barium-impregnated plastics layer which lines both the canister and the closure member. The tamper-indicating seal incorporates indicia containing information relating to the contents of the container.
