Abstract
A visible valve system for a breastmilk expression system is set forth. The visible valve system includes an outer member, graspable by a human hand. The outer member provides a visual indication that the system is properly assembled. The visible valve system can reduce spillage from a breastmilk container by providing at least a portion of a spill reducing tortuous path in the system, or the spill-reducing tortuous path may be provided in another component of a breastmilk expression system of which the visible valve system is a part.
