Disclosed are systems, methods, devices and kits for dispensing laundry
additive materials into the drum of an automatic washing machine as that
machine is used to carry out a fabric laundering operation. To bring
about such dispensing of additives, a lidded housing structure is placed
within the drum of an automatic washing machine, an insert, containing
one or more laundry additives in each compartment, is placed within the
lidded housing structure, the lid is closed and the machine is run
through the several stages of its laundering cycle. Selectively
actuatable puncturing element are provided to optionally open at least
one compartment of the insert upon closing of the housing structure lid,
thereby dispensing the contents of that opened compartment into the
washing machine drum as wash additive materials and/or to open one or
more compartments of the insert later in the laundering cycle to dispense
contents of those compartments into the washing machine drum as rinse
additive materials. The selectively actuatable puncturing element being
activated by centrifugal force arising during the spin cycle of the
laundering operation. In a multiple rinse cycle laundering operation,
selectively actuatable puncturing element has a track and cam that allows
for the dispensing of additives into the desired rinse cycle.
