- a cap body defining a chamber having only a single opening, a back wall opposite the opening and a sidewall, the chamber having means for engaging threads of an externally threaded female luer hub having an open lumen, the means being disposed near the opening,an absorbent material for holding an antiseptic agent disposed in the chamber;
a sealing component disposed within the chamber configured to sealingly engage with the lumen when the female luer hub is received into the chamber to prevent flow of the antiseptic agent into the lumen of the female luer hub while permitting the flow of the antiseptic agent past the sealing member to outwardly facing surfaces of the female luer hub, the sealing component traveling within the chamber when engaged with the female luer hub in a motion concordant with the motion of the female luer hub; and
a biasing component disposed between the back wall of the chamber and the sealing member, the biasing component biasing the sealing component towards the opening of the chamber.
