| 1. A dispenser adapted to be coupled to a container to dispense a substance in the container, the dispenser comprising:
a dispensing head comprising a pump, a motor for driving the pump, and a nozzle in fluid communication with a discharge end
of the pump;
an energy source associated with the dispensing head and electrically coupled to the motor, wherein said energy source is
generally adjacent to the container when the dispenser is coupled to a container;
a fluid flow path having a portion in fluid communication with an intake end of the pump and another portion in fluid communication
with the container; and
a valve operably coupled with the fluid flow path at a location downstream of the pump,
wherein the valve comprises a valve stem element moveable in a valve body between (i) a flow position in which fluid can pass
through the fluid flow path and (ii) a stop position in which the valve stem element prevents flow of fluid through the fluid
flow path, the valve stem element being located in the fluid flow path.
