Abstract: A trigger-actuated cleaning device dispenses an aerosol cleaning agent from a pressurized canister. The canister has a female valve assembly. In one form an over cap fits onto the canister over the valve and has a male stem on a pivotable part of the over cap that opens the valve when moved by a rod linked to a remote trigger. The stem is either formed integrally with the over cap or is removably attached to a stem socket formed in the over cap. In another form the actuator is a button having a stem that fits in the female valve.

Abstract: An overcap for use with a spray canister includes a peripheral wall adapted to attach to the spray canister, a cantilevered lever arm hingedly attached to the peripheral wall, and a nozzle within the cantilevered lever arm. The nozzle includes a stem socket adapted to receive a valve stem of the spray canister and adapted to provide a fan-shaped spray.

Abstract: A device for spraying pesticides and/or agricultural treatment chemicals has a housing configured to retain a spray canister, an actuator rod on the housing configured to contact an overcap attached to the canister, a shaft connected to the housing, and a linkage to reverse a triggering force so that the actuator pushes against the overcap. Attachments can be provided in front of the sprayer nozzle, such as a shroud to limit back spray, a rake to disturb soil prior to treatment, a tapered director to focus spray in corners, or a fan shaped outlet to provide a wide spray.

Abstract: A cleaning device includes a cleaning head, a housing connected to the cleaning head and configured to retain a spray canister, an actuator rod configured to contact an overcap attached to the canister, and a pivot link pivotally attached to the housing about a pivot point. The pivot point is positioned to allow contact between the actuator rod and the pivot link. In addition, a shaft assembly including a core is slidably disposed within the shaft assembly, with the slidable core being adapted to rotate the pivot link about the pivot point, and a handle is attached to the shaft assembly including a trigger mechanism. The trigger mechanism is adapted to move the slidable core toward the housing, which then pivots the pivot link, ultimately bringing the actuator rod into contact with the cap and causing a dispensing of contents of the canister.
