## Abstract

A method for dispensing a product from an interior volume of a container to which a power assembly is secured, which includes rotating an actuator sleeve of the power assembly in one direction relative to the container to draw an amount of the product from the interior volume into a pump chamber and to pressurize the pump chamber, and temporarily depressing an actuator of the power assembly to dispense a portion of the product from the pump chamber through a nozzle for a duration of time during which the actuator is temporarily depressed. During the duration when the product is dispensed from the container, the power assembly does not rotate relative to the container, and the power assembly is never rotated in an opposite direction.

## Claims

### Claim 1

A method for dispensing a product from an interior volume of a container to which a power assembly is secured, the method comprising:
(1) rotating an actuator sleeve of the power assembly in one direction 360° or less relative to the container to draw an amount of the product from the interior volume into a pump chamber and to pressurize the pump chamber;
(2) temporarily depressing an actuator of the power assembly to open a valve that is in fluid communication with the pump chamber and that is normally biased to be in a closed position to dispense a portion of the product from the pump chamber through a nozzle for a duration of time during which the actuator is temporarily depressed;
(3) releasing pressure on the actuator to permit the valve to return to the closed position before all of the product drawn in the pump chamber in step (1) is dispensed through the nozzle;
(4) re-depressing and re-releasing pressure on the actuator sequentially one or more times until all of the product drawn in the pump chamber in step (1) is dispensed through the nozzle; and
(5) repeating steps (1) through (4) to draw addition amounts of the product from the interior volume of the container and to dispense the additional amounts of the product through the nozzle;
wherein, during the duration when the product is dispensed from the container, the power assembly does not rotate relative to the container, and
wherein the power assembly is never rotated relative to the container in a direction opposite the one direction of rotation in step (1).

### Claim 2 (depends on 1)

The method according to claim 1, steps (1) through (5) are repeated sequentially until all amounts of the product in the interior volume container that are capable of being drawn into the pump chamber in step (1) have been dispensed.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the container is a hand-held container, wherein the actuator sleeve is rotated by hand, and wherein the actuator is temporarily depressed by application of pressure by hand.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the product is dispensed from the nozzle in the form of a spray.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the power assembly is permanently secured to the container.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the actuator is not rotated at all relative to the container between steps (3) and (4).

### Claim 7 (depends on 1)

The method according to claim 1, wherein in step (1), the actuator sleeve is rotated in the one direction relative to the container for only a partial portion of a full turn.

### Claim 8 (depends on 1)

The method according to claim 1, wherein pressurization of the pump chamber in step (1) is effectuated using an energy storage device.

### Claim 9 (depends on 8)

The method according to claim 8, wherein the energy storage device utilizes one or more springs, elastics or gases to exert pressure on a piston that pressurizes the pump chamber.

### Claim 10 (depends on 9)

The method according to claim 9, wherein the energy storage device pre-stressed or pre-compressed to exert sufficient pressure on the piston that the product drawn in the pump chamber in step (1) is dispensable when the piston is near an at-rest position relative to a bottom of the pump chamber.
