Paint tote with colapsible liner and tote agitator

A tote tank has a flexible, collapsible liner for water-based or water-borne paint. The liner when full of paint fills the tank and lines the interior walls thereof. A paint outlet from the liner extends through a wall of the tank for withdrawing paint. A paint inlet to the liner is provided for filling the line with paint and is normally closed and sealed by a closure plate. An air inlet to the tank allows the liner to collapse as paint is withdrawn. The tank is mounted on a pivot and cranks are linked to the tank to rock it back and forth to keep the paint in an agitated condition.
