A dispenser includes a dispenser body having an interior cavity, and an aperture that communicates with the interior cavity. The dispenser also includes a loading door and a lid. The lid engages a dispenser surface when in the closed position to thereby create a substantially gas impermeable seal. The dispenser further includes a mounting surface disposed within the interior cavity and proximal the aperture. The mounting surface includes a mounting interface that permits substantially gas impermeable mounting of a cartridge while permitting access to the cartridge from the exterior of the dispensing body through the aperture.
