Abstract From the Canadian patent

A squeeze bottle is internally provided with a partition wall forming an overflow edge for producing a liquid stream which may be directed arbitrarily in any desired direction, especially for cleaning toilet bowls. A discharge nozzle is connected to the smaller chamber separated from the main chamber of the bottle by the partition wall. An immersion pipe projects to the bottom of the smaller chamber and determines the direction of spray. This direction assumes an angle of about 40° to the longitudinal central axis of the bottle. By tilting the bottle the smaller chamber may be refilled with the liquid present in the main chamber of the bottle.
