Abstract
The present invention is directed to a device for dispensing a unit dose water-soluble pouch containing a laundry additive during the spin cycle of a washing machine process having a spinning wash drum. The device is attached to the vertical center post of a washing machine and holds a water-soluble pouch above the high water level. During the spin cycle, the spinning center post will create sufficient centrifugal force so that the water-soluble pouch is released from the device. The water-soluble pouch will then fall into the laundry where the water-soluble pouch will dissolve when rinse water fills the machine thereby releasing the laundry additive to treat the washed articles.
