Abstract

A medical solution container includes a bag portion for storing solution and a header portion which incorporates an improved outlet port in communication with the bag portion for receiving and holding a spike from an administration set. The outlet port has, at a distal end from the bag portion, a generally inwardly inclined tapered annular collar which, at its widest diameter portion, joins a substantially cylindrical coaxial bore section. The cylindrical bore section has a first section with a reduced diameter which adjoins a second section having an enlarged diameter. The second section is located at an end of the outlet port proximate the bag. A pierceable diaphragm for sealing the outlet port is supported at the junction of the reduced and enlarged diameter bore sections and lies substantially in a plane which is at an angle to a normal to the insertion direction of the spike or the axial direction of the cylindrical bore. By providing the diaphragm at an angle, which is preferably between about 5.degree. and about 20.degree., the force required to pierce the diaphragm with the spike is reduced while a reliable holding force is maintained after the spike has been inserted, to frictionally hold the spike in the outlet port.
