摘要：
A product dispensing system includes a housing that has a sidewall with at least one orifice and at least one protrusion in alignment with the at least one orifice. An exterior surface of the at least one protrusion provides a visual contrast in color, texture, or surface finish that differs from that of an exterior surface of the sidewall adjacent the orifice.
