<p>A resealable vial featuring a fluid access device having a membrane for selectively opening or sealing a fluid passageway between the bottle and the fluid access device. The vial includes a body disposed on said bottle. The fluidaccess device can be configured as a spike assembly, a needle assembly, or a luer lock assembly, and features a hollowed rod in sliding, fluid-tight relation to an orifice defined by the body. A membrane, preferably formed from an elastomeric material, is secured across both the orifice and the open top of thebottle, and may be retained between the top surface of the bottle and the body. The membrane preferably includes a central area sealing the orifice from the open top of the bottle, with one or more fluid passages defined on a portion of the membrane outside of the central area. A force exerted upon the hollowed rod deflects the membrane towards the interior of the vial, urging the membrane and fluid openings away from the body to open the fluid path between the bottle and the orifice. A sealing rib may be provided around the portion of the periphery of the recess for sealing contact between the central area of the membrane and the orifice.</p> |
