will consistently open during the spin cycle with prior art dispensers such as those having an aperture that is sealed with a valve that is tethered to a movable weight operation of the device can be adversely influenced by conditions in the washing machine for instance when the dispenser is fully loaded with a solid laundry product the weight may not move far enough so that the aperture becomes only partially opened furthermore when using prior art dispensers in some automatic washing machines liquid products can be displaced by the movement of the weight or dissolved away by water seeping into the dispenser during the spin cycle resulting in a waste of product with other devices fluctuations in temperatures and or pressure inside the dispenser chamber may cause the aperture to open prematurely or too late although dispensers with two apertures are most preferred it is contemplated that the inventive dispenser may have only a single aperture or may have a plurality of apertures dispensers with a single aperture can be designed so that the aperture will consistently face the interior of the washing machine basket during the spin cycle this in turn will insure that the laundry product remains within the dispenser chamber until the spin cycle has terminated referring to the lower portion of the dispenser as shown in fig5 and 6 for instance a single aperture dispenser will be fabricated by simply enclosing this lower portion this single aperture device can further include means for orienting the device while under the influence of centrifugal force within the washing machine basket this may include making the portion of the dispenser that is opposite the aperture heavier since it is known that centrifugal force.
