ABSTRACT:
Improved port and closure constructions are disclosed for medical solution containers, particularly collapsible containers intended for storing and administering parenteral solutions. An outlet port includes a tubular neck with an elastomeric sealing disc held against the distal end of the neck by a tear-off cap, the disc having planar surfaces and a circumferential rib spaced from each of those surfaces for sealingly engaging the inside of the cap. Within the outlet port is an annular collar that slopes and tapers distally inwardly for engaging the spike of an administration set. An inlet port is also provided, such inlet port having a neck with an internal annular distally-facing shoulder and a plurality of longitudinal internal ribs located distal to the shoulder. The ribs are useful for guiding a stopper into sealing engagement with the shoulder without interfering with the seal as so formed.
