ABSTRACT:
A gravity discharge device for liquids, especially concentrated liquid detergents, comprises a valve guide system whose surface area optimizes liquid flow. The discharge is especially useful with concentrated (“2×”) liquid detergents, whose viscosities tend to unacceptably slow their flow rate from home-use containers, especially when the containers progressively empty after multiple uses.
