1. A disinfection cap having a housing comprising:
a top wall and a cylindrical sidewall having an inner surface defining a cavity, and an outer surface,
an open bottom formed by the cylindrical sidewall with an opening to the cavity within said housing for receiving a hub of a luer connector;
an open cell foam structure disposed within the cavity, the open cell foam structure abutting a top wall of the cavity, the open cell foam structure being impregnated with disinfectant fluid in a pre-activated state; and
a closed cell foam structure disposed against the open cell foam structure, the closed cell foam structure being configured as a blockage feature for fluidly blocking the hub of the luer connector, wherein when the hub of said luer connector is received within said inner surface of said cavity wherein the open cell foam structure is bonded to the closed cell foam structure, the closed cell foam structure and the open cell foam structure both have the same non-circular cross-sectional shape said non-circular cross-sectional shape is configured to create an interference fit with the inner surface of the cavity while still permitting fluid to flow from the open cell foam structure disposed between the top wall and the closed cell foam structure upon compression of the open cell foam structure.
