A disposable applicator (10) for dispensing a desired quantity of a substantially non-runny medicant, including a housing (14), a plunger (16), and a replaceable cap (12). The housing (14) is generally tubular having opposing proximal and distal ends and a tapered inner surface (52) extending therebetween. The distal end terminates in a dispensing nozzle (69) that defines a dispensing passageway (84) in substantial coaxial alignment with t he housing (14), while the inner surface has an alignment device (80). The plunger (16) has a peripheral edge (96) and is configured for axial movement within the housing (14), where the peripheral edge (96) is aligned by the alignment device (80) and slidingly guided by the inner surface (52), supporting the plunger (16) therein. The plunger (16) is configured for slidable advancement toward the dispensing opening (90) by exertion of force by a user, so as to urge the medicament through the passageway (84).
