Abstract

A dispensing apparatus for use with a replaceable unit dose package has at least one cavity sealed by a membrane, wherein the cavity contains additive materials to be dispensed. The dispensing apparatus is configured for use, for example, in a washing machine, wherein the washing machine has a plurality of cycles. The dispensing apparatus comprises a dispensing director having a dispensing signal generator and a monitor for distinguishing among a plurality of washing machine operating cycles. The dispensing apparatus further includes an actuator in communication with said dispensing director and configured to selectively electromechanically open the membrane in response to a dispensing signal, thereby releasing additive materials from said at least one cavity. Also disclosed is a disposable unit dose package for use in a washing machine and with a dispensing apparatus having a dispensing director and an electromechanical actuator in communication with said dispensing director. Still further disclosed is a kit, system, and method of dispensing laundry additive materials into a rotating washing machine having a drum.

Claims (18)

1. A dispensing apparatus for use with a replaceable unit dose package having at least one cavity sealed by a membrane, the at least one cavity containing additive materials to be dispensed and said dispensing apparatus for use in a machine, the machine having a plurality of cycles, said dispensing apparatus comprising:

a dispensing director comprising a dispensing signal generator and a monitor for distinguishing among a plurality of machine operating cycles;

at least one sensor associated with the dispensing director and comprising a switch for detecting inertia, wherein the switch comprises a coiled spring having a free end at least partially surrounding a post displaced within the spring along the spring's longitudinal axis; and

an actuator in communication with said dispensing director and configured to electromechanically open the membrane in response to a dispensing signal, thereby releasing additive materials from said at least one cavity.

2. The dispensing apparatus of claim 1 wherein the at least one sensor comprises two switches oriented effectively perpendicularly to one another.

3. A dispensing apparatus for use with a replaceable unit dose package having at least one cavity sealed by a membrane, the at least one cavity containing additive materials to be dispensed and said dispensing apparatus for use in a machine, the machine having a plurality of cycles, said dispensing apparatus comprising:

a dispensing director comprising a dispensing signal generator and a monitor for distinguishing among a plurality of machine operating cycles;

at least one sensor associated wit the dispensing director, wherein the at least one sensor comprises two switches oriented effectively perpendicularly to one another; and

an actuator in communication with said dispensing director and configured to electromechanically open the membrane in response to a dispensing signal, thereby releasing additive materials from said at least one cavity.

4. A dispensing apparatus for use with a replaceable unit dose package having at least one cavity sealed by a membrane, the at least one cavity containing additive materials to be dispensed and said dispensing apparatus for use in a machine, the machine having a plurality of cycles, said dispensing apparatus comprising:

a dispensing director comprising a dispensing signal generator and a monitor for distinguishing among a plurality of machine operating cycles;

at least one sensor associated wit the dispensing director, wherein the at least one sensor comprises a switch for detecting inertia; and

an actuator in communication with said dispensing director and configured to electromechanically open the membrane in response to a dispensing signal from the dispensing director, thereby releasing additive materials from said at least one cavity.

5. A dispensing apparatus for use with a replaceable unit dose package having at least one cavity sealed by a membrane, the at least one cavity containing additive materials to be dispensed and said dispensing apparatus for use in a machine, the machine having a plurality of cycles, said dispensing apparatus comprising:

a dispensing director comprising a processor, a dispensing signal generator, and a monitor for distinguishing among a plurality of machine operating cycles;

at least one sensor associated with the dispensing director, wherein the at least one sensor comprises a switch; and

an actuator in communication with said dispensing director and configured to electromechanically open the membrane in response to a dispensing signal from the dispensing director, thereby releasing additive materials from said at least one cavity;

wherein the processor is configured by programming to identify spin cycles based upon signals received from the at least one sensor.
