ABSTRACT:
An administration port (14) for medical fluid containers (10) is provided which creates a proper seal with a broad dimensional range of cannulas. The port includes an inwardly tapered end 28 which can flex outwardly during insertion of a cannula (16). The inwardly tapered end 28 works in conjunction with an inner surface (32) of the sidewall (18) and end (28) to provide a unique sealing construction, to minimize friction between the port (14) and the cannula (16) during insertion of the cannula (16) and to inhibit inadvertent removal of the cannula. Selective removal of the associated cannula requires relatively little force, however.
