ABSTRACT:
An additive dispensing device including a container, adapted for use with an appliance such as a washing machine. The container has an interior additive receiving space formed in part by side wall means with at least a portion thereof formed with a curved surface. A water inlet spout is adapted to discharge water into the interior space generally tangentially to the side wall curved surface. The spout is located in axial alignment with the space outlet which is in turn in direct fluid communication with a siphon inlet. The space outlet includes a water flow guide portion. Upon water being discharged from the spout the guide portion operates to divert a quantity of the water flow creating a stall-like condition adjacent the space outlet. As a consequence a first portion of the flow is directed into the space outlet and a second portion of the flow enters the space and impinging on the wall curved surface to induce a swirl-like diluting flow therein. The siphon operates, as a result of the first flow portion, through the full range of spout flow rates to induce a full flowing siphon substantially immediately upon the water flow exiting the spout.
