Abstract

Controlled sanitizing by dispensing a germicide, such as a disinfectant, antibacterial solution or cleansing agent at intervals. A method of replacing an aerosol canister from a sanitizer mounted proximate to a door handle on a door is disclosed. The method includes pivoting a cover of the sanitizer in a first direction to expose the aerosol canister while a remainder of the sanitizer housing remains stationary relative to the door; moving a guide wheel to a loading position; removing the aerosol canister and a valve coupled thereto from a seat within the sanitizer housing; positioning a replacement aerosol canister in the seat so that a valve thereof is oriented toward the door handle; moving the guide wheel to an operative position in which it seats in rotatable proximity to the valve; and closing the cover by pivoting the cover in a second direction. The method ensures that a suitable aerosol can has been properly loaded in the dispenser.

Claims

1. A method of replacing an aerosol canister from a sanitizer mounted proximate to a door handle on a door, comprising the steps of:

pivoting a cover of the sanitizer in a first direction to expose the aerosol canister while a remainder of a sanitizer housing remains stationary relative to the door;

moving a guide wheel to a loading position;

removing the aerosol canister and a valve coupled thereto from a seat within the sanitizer housing;

positioning a replacement aerosol canister in the seat so that a valve thereof is oriented toward the door handle;

moving the guide wheel to an operative position in which it seats in rotatable proximity to the valve; and

closing the cover by pivoting the cover in a second direction.

2. The method of claim 1, wherein the seat comprises a retaining clamp, the method further including the steps of:

positioning the retaining clamp from a first position proximate the aerosol can to a remote position, thereby freeing the aerosol canister and the valve coupled thereto from the seat within the sanitizer housing, the clamp positioning step being prior to the step of removing the aerosol canister; and

returning the retaining clamp to the first position after positioning the replacement aerosol canister.

3. The method of claim 1, wherein the seat comprises a mounting bracket and wherein the removal and replacement positioning of the aerosol can is from the mounting bracket.

4. The method of claim 3, including the step of engaging an exterior of the aerosol can using the mounting bracket.

5. The method of claim 4, wherein the engaging step includes the step of flexing arms associated with the mounting bracket in response to removal and replacement positioning of the aerosol can.

6. The method of claim 1, including the step, prior to closing the cover, of setting a timing cycle using a switch disposed within the housing, the switch being concealed when the cover is pivoted to a closed position.

7. The method of claim 1 further comprising the step of unlocking the cover prior to the opening step.

8. The method of claim 1, including the step of maintaining a pivotal connection between the cover and the remainder of the sanitizer housing throughout the pivoting, removing, positioning, and closing steps.

9. A device for spraying an aerosol onto a door handle of a door comprising:

a housing mounted to the door;

a seat for receiving an aerosol canister having a valve;

an attachment coupled to the valve and oriented toward the door handle, the attachment having a bearing surface;

a guide supported by the housing having a first position in abutting contact with the attachment;

an arm coupled to the bearing surface to thereby open the valve, and

a timing circuit operative to dispense the aerosol in an automated manner onto the door handle, by moving the arm.

10. The device of claim 9 wherein the guide is a rotatable wheel.

11. The device of claim 10 wherein the guide wheel comprises at least one groove for seating the attachment.

12. The device of claim 10 further comprising a slot which defines a movement of the guide wheel within a boundary of the slot.
