Abstract

A resealable access site (10) is provided for allowing a cannula (18) multiple accesses to an internal cavity (35) defined by a container (12). The access site (10) includes a first conduit (28) defining a passageway (29) forming a fluid path to the cavity within the container. Sealingly attached to the conduit (28) is a housing (26) with a lower portion (26a) and a lower flange (68) attached to a lower end of the lower portion and extending radially inward from the lower portion. A septum (24) is disposed and compressed within the lower portion, with the septum defining an opening (46) extending upward through at least a portion of the septum. The opening (46) is sized for insertion of the cannula (18) through the septum (24) with the septum sealing about the exterior of the cannula. The septum (24) is maintained in the housing by the support provided by the opposing flange (68) and conduit (28).
