Tamper-resistant devices and systems for wall-mounted dispensers

An accessory device system for a wall-mounted dispenser, comprising:

• an accessory device for a dispenser, wherein the dispenser is configured to mount to a wall and has a perimeter edge juxtaposed with the wall when the dispenser is in a closed position and mounted to the wall, the perimeter edge including a top edge, a left side edge, a right side edge, and an underside edge, the accessory device comprising:
• a plate having a thickness and having a front surface and a rear surface wherein the thickness is the distance between the front and rear surfaces, the plate further having an underside surface generally normal to the front surface and rear surface, the plate further having an outer surface generally normal to the front surface and the rear surface and excluding the underside surface, wherein the underside surface is shaped to generally match the top edge, a portion of the left side edge proximate to the top edge, and a portion of the right side edge proximate to the top edge, wherein when the dispenser is mounted to the wall and in a closed position and the rear surface of the plate is generally parallel to and coupled to the wall, a first gap exists between the underside surface and the top edge, a second gap exists between the underside surface and the left side edge, a third gap exists between the underside surface and the right side edge, wherein each gap is configured such that the dispenser is able to be opened and closed when the dispenser and the accessory device are mounted to the wall;
• and
• a backing plate, wherein the backing plate is interposed between the dispenser and wall when the dispenser is mounted to the wall, and wherein the backing plate is interposed between the accessory device and the wall when the dispenser is mounted to the wall, and the accessory device is coupled to the backing plate.

A method for preventing tampering of a wall-mounted dispenser, wherein the dispenser is configured to mount to a wall and has a perimeter edge juxtaposed with the wall when the dispenser is mounted to the wall and in a closed position, the perimeter edge including a top edge, a left side edge, a right side edge, and an underside edge, including the steps of:

• coupling an accessory device to a wall, the accessory device comprising a plate having a thickness and having a front surface and a rear surface wherein the thickness is the distance between the front and rear surfaces, the plate further having an underside surface generally normal to the front surface and rear surface, the plate further having an outer surface generally normal to the front surface and the rear surface and excluding the underside surface, wherein the underside surface is shaped to generally match the top edge, a portion of the left side edge proximate to the top edge, and a portion of the right side edge proximate to the top edge, and
• coupling the wall-mounted dispenser to the wall proximate to the accessory device such that when the dispenser is in a closed position and the rear surface of the plate is generally parallel to and coupled to the wall, a first gap exists between the underside surface and the top edge, a second gap exists between the underside surface and the left side edge, a third gap exists between the underside surface and the right side edge, wherein each gap is configured such that the dispenser is able to be opened and closed after mounting to the wall.
