the tip 106 is urged downward into the first passageway 46 and until the flange 96 clears the first passageway 46 and the uppermost portion of the primary valve sealing surface 50 the flange 96 maintains a fluid tight secondary seal with the first passageway 46 the flange 96 deforms slightly more as the valve element 80 moves downward and the first passageway 46 tapers as shown in fig7 when the valve element 80 is initially urged downward the shoulder 92 moves downward away from the primary valve sealing surface 50 thereby breaking the primary valve seal the flange 96 moves downward within the first passageway 46 while the connector tip 106 moves downward and the flange 96 provides a continuous confirming seal until the connector 100 is locked into place over the first end 42 during this downward movement the elastic bands 98 elongate in response to the downward force placed on the valve element 80 by the tip 106 fluid can pass between the primary seal elements the shoulder 92 and the secondary valve sealing surface 50 but is prevented by the secondary valve seal the flange 96 and the secondary valve sealing surface 48 from communicating with the tip 106 fig8 shows the valve element 80 in the down or open position wherein the top surface 82 and the flange 96 have cleared the first passageway 46 and the uppermost portion of the primary valve sealing surface 50 breaking the secondary valve seal and permitting passage of fluid from the tip 106 through the first passageway 46 and the second passageway 66 fluid urged into the tip 106 through the male luer connector 100 can pass through the valve assembly 10 and out the second end opening 65 or in the.
