Device and related compositions and methods for use in surface decontamination

A device for applying an indicator composition and, optionally, a disinfectant composition, to at least one of a plurality of articles dispensed through the device, the device comprising:

• a housing at least partially surrounding an interior volume and having (i) an exterior wall defining a dispensing aperture extending through the exterior wall, the exterior wall forming an upper surface of the device or a side surface of the device, and (ii) a lower end region sized to couple to a canister holding the article, the lower end region of the housing comprising an opening through which the at least one of the plurality of articles is drawn from the canister into a dispensing mechanism positioned within the interior volume of the housing, and one or more connecting features configured to removably couple the lower end region to the canister;
• the dispensing mechanism positioned within the interior volume of the housing comprising a plurality of rollers configured to capture and direct the at least one of the plurality of articles through the interior volume of the housing towards the dispensing aperture;
• an optionally removable cartridge containing a penetrable barrier extending through a portion of a cartridge housing, the cartridge housing defining an interior volume of a reservoir, the removable cartridge being coupled, optionally removably coupled, to the device housing, the interior volume of the reservoir comprising at least one chamber sized to contain the indicator composition and, optionally, a second chamber sized to contain the optional disinfectant composition or a component of the indicator composition;
• and
• an application mechanism positioned within the interior volume of the housing relative to the dispensing aperture, the application mechanism comprising at least one applicator and a transfer element which includes a pump element, wherein at least a portion of the application mechanism is placed in fluid communication with the reservoir of the optionally removable cartridge;
• and
• an optional actuator configured to simultaneously activate the pump element of the application mechanism and the dispensing mechanism to apply an amount of the indicator composition, and optionally an amount of the optional disinfectant composition or the component of the indicator composition, from the reservoir to the at least one of the plurality of articles as it dispenses through the dispensing aperture.
