Abstract
A containment system for packaging a plurality of products that are to be accessed in a predetermined sequence. The containment system includes a plurality of product compartments that each holds at least one of the plurality of products. Indicators having a gas reactive material that changes appearance after a predetermined period of time of exposure to ambient air are deployed when gas cover seals are removed or broken to access a product in the product compartment.
Claims15
A containment system for a plurality of products that are to be accessed in a predetermined timed sequence, the containment system comprising:
- a substrate with a plurality of product compartments, each of said product compartments having a volume sufficient to receive at least one of a plurality of products, said substrate further including a plurality of atmospheric gas conduits each leading from one of the product compartments to a gas sensitive indicator window chamber;
- a plurality of gas sensitive indicators having a gas reactive material that changes appearance at a predetermined time after exposure to ambient air, said gas sensitive indicators being located within a gas sensitive indicator window chamber;
- and
- a plurality of gas seals each sealing one of the plurality of the product compartments against atmospheric gases so that disrupting the gas seal to access a product in the product compartment allows atmospheric gas to enter the product compartment and from there to flow through one of the plurality of atmospheric gas conduits to expose at least one of the gas sensitive indicators, the one gas sensitive indicator exposed to ambient air being arranged to change appearance in a manner that indicates at least one next product in the predetermined sequence to be accessed after the predetermined time after exposure has elapsed.
A containment system for a plurality of products that are to be accessed in a timed sequence, the containment system comprising:
- a plurality of product compartments, each of said product compartments being adapted to hold at least one of said plurality of products;
- a plurality of gas sensitive indicators adapted to change appearance after exposure to ambient air, at least one of said gas sensitive indicators being located within a gas sensitive indicator window volume;
- and
- a plurality of atmospheric gas conduits each leading from one of the product compartments to one of said gas sensitive indicator window chambers, such that an exposure of one of said product compartments to gain access to a product in said one product compartment allows atmospheric gas to enter the product compartment and from there to flow through at least one of the plurality of atmospheric gas conduits that leads from said exposed product compartment to expose at least one of the gas sensitive indicators, the one gas sensitive indicator exposed to ambient air being arranged to change appearance in a manner that indicates that a next product in the timed sequence is to be accessed.
