Abstract
A container for holding and dispensing fluid has a flexible bag to which a spout is connected. A specially designed adapter within the spout has an opening sealed by a plug. A tubular probe is inserted into the adapter opening and snapped onto the plug. The connected probe and plug are pushed into the bag to permit fluid to flow through apertures in the probe. The probe channel is filled with fluid before insertion into the bag, thus introducing substantially no air into the system. Withdrawing the probe snaps the plug back into the adapter to re-seal the bag without substantial introduction of air, and without any leakage.
