A handwashing valve structure includes a mounting structure, a dispensing structure, and a control structure. The mounting structure is configured to attach to a liquid vessel. The dispensing structure is configured to dispense a liquid from the liquid vessel and is movable between a closed position and an open position. The control structure is configured to move the dispensing structure between the closed position and the open position. The control structure is configured to be moved by pressure from a portion of a user's body to move the dispensing structure from the closed position to the open position. The dispensing structure is configured to automatically move from the open position to the closed position in the absence of any pressure from the portion of the user's body onto the control structure.
