The inventive applicator has a pliable plastic tube for holding a hermetically sealed crushable glass ampoule containing fluid to be dispensed from the applicator and applied by the applicator to a surface, and a pliable dispensing member mounted onto the plastic tube. The dispensing member has a dauber from which the fluid is dispensed and a protective device which surrounds a portion of the tube and is squeezed inwardly between the user's forefinger and thumb to cause the portion of the tube positioned thereunder to deform inwardly and crush the crushable glass ampoule positioned within the tube to release the fluid contained within the ampoule. The protective device guards against and minimizes the chances of users being cut by glass shards of the crushed glass ampoule when the protective device is subsequently squeezed inwardly to cause the fluid to move through the applicator to the dauber.
