An exemplary table top sanitizer dispenser bottle base includes a movable upper housing, the upper moveable housing has a floor with an aperture located therein and a peripheral wall. The top sanitizer dispenser bottle includes a lower stationary housing. The upper movable housing is connected to the lower stationary housing and is configured to move linearly upward and downward with respect to lower stationary. One or more biasing members bias the upper movable housing upward. A switch is included and the upper movable housing has an engagement member or surface for actuating the switch upon downward movement of the upper movable housing.

Abstract: The sprue/riser sleeve 40 has a tubular, preferably cylindrical wall 42 extending between an inlet end 48 and an outlet end 50. The sleeve 40 has a woven mesh filter extending across a central passageway 51 with a periphery 54 of the filter 52 embedded into the wall 42. The periphery 54 has three or more, evenly spaced tabs 56 formed thereon that project further into or through the wall to secure the filter to the wall without materially weakening the wall. Preferably, the filter has a square-shaped periphery 54 with corners 64 that define the tabs 56. The main portion of the periphery extends into the wall less that one-half the thickness of the wall, whereas the tabs extend into the wall a distance greater than one-half the thickness.
