1. An overcap for a dispenser, comprising:
- a housing mountable on a container, wherein the container includes a tilt-activated valve stem with a discharge end, and wherein the discharge end of the valve stem is configured to be in fluid communication with a discharge orifice of the housing; and
a drive unit disposed within and supported by the housing, wherein the drive unit includes a solenoid having an armature, wherein the armature is configured to move along a path substantially parallel to a longitudinal axis of the housing, and wherein movement of the armature imparts transverse motion to the valve stem to open a valve of the container for a predetermined spraying period that is determined by the selection of an automatic operation mode associated with the overcap and is followed by a predetermined period where the solenoid is de-energized, and wherein the armature, or any movable structure associated therewith, for imparting motion to the valve stem is unrestricted by the housing.

Abstract
An overcap for a dispenser includes a housing mountable on a container. The container includes a tilt-activated valve stem with a discharge end. The discharge end of the valve stem is adapted to be in fluid communication with a discharge orifice of the housing. A drive unit is disposed within the housing, wherein the drive unit includes a solenoid, a bi-metallic actuator, a piezo-linear motor, or an electro-responsive wire, which is adapted to impart transverse motion to the valve stem to open a valve of the container.

9. An actuator for a dispenser, comprising;
-
a container having a tilt-activated valve stem with a discharge orifice; a dispensing member disposed on a portion of the valve stem, wherein a conduit of the dispensing member is in fluid communication with the discharge orifice of the valve stem and with a discharge orifice of a housing; and a drive unit supported by the housing and having means for engaging the dispensing member to place the tilt-activated valve stem in an operable position for a predetermined spraying period, wherein the dispenser includes more than one automatic operating mode, and wherein a longitudinal axis of the drive unit is disposed parallel to a longitudinal axis of the container, and wherein the drive unit means for engaging the dispensing member is unrestricted by the housing. - View Dependent Claims (10, 11, 12)

13. An overcap for a dispenser, comprising:
-
a housing configured to be mounted on a container having a tilt-activated valve stem, wherein the housing includes a discharge orifice; a dispensing member configured to be disposed on a portion of the valve stem, wherein a conduit of the dispensing member is in fluid communication with a discharge end of the valve stem and the discharge orifice of the housing; and a drive unit disposed within and supported by the housing, wherein the drive unit includes a solenoid having an armature configured to impart transverse motion to the dispensing member for a predetermined time period followed by a predetermined sleep period where the solenoid is de-energized, and wherein the armature is configured to move along a path substantially parallel to a longitudinal axis of the housing, and wherein the armature, or any movable structure associated therewith, for imparting motion to the dispensing member is unrestricted by the housing. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for dispensing, comprising:
-
providing a housing mounted on a container having a tilt-activated valve stem with a dispensing member thereon and a drive unit disposed within and supported by the housing, wherein the drive unit includes a solenoid with an armature; generating an electrical signal in response to one of a timer, sensor, or manual actuation; moving the armature along a path substantially parallel to the longitudinal axis of the container to displace the dispensing member for a predetermined time, and wherein the armature, or any movable structure associated therewith, for displacing the dispensing member is unrestricted by the housing; discharging fluid through a discharge orifice into the atmosphere external to the housing; and entering a sleep period where the solenoid is de-energized.
