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).

[ What is claimed is:] [1.] An access site for allowing a cannula multiple accesses to a fluid passageway, the site comprising;a first generally flexible conduit having a lower portion defining the passageway, a lower end of the lower portion forming a ring shaped land area;a housing including a lower portion having an upward extending inner surface, a radially extending flange attached to a lower end of the lower portion and extending inward from the lower portion, the housing also including an upper portion, the lower portion of the first conduit being sealingly attached to the upper portion; anda septum compressingly disposed within the lower portion of the housing, the septum defining an opening extending upward through at least a portion of the septum, the opening sized for sealed insertion of the cannula through the septum, the septum having an upper surface with an upper outer circumferential edge portion and a lower surface with a lower outer circumferential edge portion, the conduit being connected to the housing so that the ring shaped land area is immediately adjacent the upper outer circumferential edge portion of the septum to support the septum against displacement upward upon insertion of the cannula and the radial flange extending over the lower outer circumfernetial edge portion to define a target access opening to the septum.
