Abstract:
1. A self-sealing male connector device for connection with a female connector device, the female connector device having an inner engagement surface that is smaller in diameter than the male connector device, the self-sealing male connector device comprising: a male body having a first end, the first end having a first diameter when in its natural disconnected configuration and a second diameter smaller than the first diameter when the first end is connected with the smaller-diameter inner engagement surface of the female connector device and is thereby forced to a contracted configuration; and a closure cap disposed at the first end of the male body that closes the male body against fluid flow, the closure cap having a diameter and being mounted to the male body so that the closure cap diameter varies with diameter variations of the first end of the male body, the closure cap having an aperture formed such that the aperture is closed when the male body is disconnected from the female connector device and is in its natural disconnected configuration and the aperture is open to permit fluid flow through the closure cap when the diameter of the closure cap is caused to contract as the male body is moved to its contracted configuration due to connection with the smaller-diameter female connector device; wherein the male body comprises a tubular wall extending to the first end of the male body, the tubular wall being formed of a first segment and a second segment with the second segment being more flexible than the first segment.
