A
system for introducing
laundry additive materials to an automatic washing
machine comprises a unit
dose package including a first compartment containing a first
laundry additive material, a second compartment containing a second
laundry additive material, and optionally at least a third compartment containing a third laundry additive material, and a dispenser. The dispenser is adapted for interchangeable use with unit
dose packages containing two, three or more compartments, and includes a housing structure comprising a first chamber adapted to receive the unit
dose package. The housing structure is arrangeable in a first position to receive the unit dose
package and a second position to secure the unit dose package in the first chamber. The dispenser further includes first compartment piercing elements adapted to open the first compartment and, if included, the third compartment; a second compartment piercing element adapted to open the second compartment; and a second chamber in fluid communication with the first chamber. The first compartment piercing elements are adapted to open the first compartment and the third compartment, if included, by arranging the housing structure from the first position to the second position, and at least the first compartment and the third compartment, if included, are adapted to then release the first laundry additive material and the third laundry additive material, if included, for gravitational flow for use in a wash cycle. The second compartment of the unit dose package is adapted to release the second laundry additive material to the second chamber during a spin cycle.
