Claim 1
Independent Claim
162 words
A closure system comprising a connector including means for defining a luer fitment having an interior bore and wall means for defining a skirt peripherally surrounding said luer fitment, a cap for joining to said connector, said cap having an exterior wall surface and an interior wall surface defining an interior chamber into which said luer fitment is advanced as said cap and connector are joined and in which a liquid antiseptic is retained, and means associated with said cap and said connector forming a continuous first seal area between said exterior cap wall surface and said connector skirt and a continuous second seal area between said interior cap wall surface and said luer fitment for trapping the retained liquid antiseptic within said cap chamber as said cap and said connector are joined and for directing the liquid antiseptic from said cap chamber into said interior bore of said luer fitment as said luer fitment is advanced into said interior cap chamber.
Claim 2
Dependent Claim
