Abstract
A dispensing pouch containing premeasured laundry compositions comprises a flexible, porous pouch having a plurality of valves or supplementary openings along its edges. The dispensing pouch permits rapid dispersion of a highly soluble laundry detergent through the pouch valves, which open as the pouch is compressed during laundry agitation in a machine washer. Washer-resistant fabric softener/antistatic chips larger than the pouch valve openings remain inside the pouch through wet cycles, to be dispensed as they melt and wick through the porous pouch fabric in a machine dryer.
