Abstract
A connector member for a fluid flow path is provided which comprises a transparent housing enclosing an opaque barrier membrane or wall portion blocking flow through the flow path. The barrier membrane is adapted to be openable by exposure to radiant energy from the exterior through the transparent housing. In accordance with this invention, the barrier membrane is made of a predominantly crystalline plastic material, and, accordingly, exhibits a relatively sharp melting point for improved opening characteristics upon exposure to the radiant energy.
