An applicator for applying fluid, liquid, gel, medicine or lotion to the human body. The applicator has a handle, an applicator head and a pivot lock. The pivot lock positions the applicator head at a number of discrete positions with respect to the handle. The applicator head has a clevis with a first fork and a second fork. The first fork and the second fork have star-shaped openings. The handle has a base with a star-shaped aperture. A star-shaped extrusion on the pivot lock fits through the star-shaped openings and the star-shaped aperture to lock the position of the applicator with respect to the handle. The pivot lock also has a spring rod with a spring a compression spring around it. The spring is compressed between a shoulder and a spring rod cap. The spring rod fits into a spring rod opening in a structural member between the clevis and a dispenser portion of the applicator head. When the spring rod is placed through the spring rod opening, the spring is placed around the pivot and compressed against an annular shoulder of the applicator head. A pivot cap is then placed on the pivot to retain the spring. The spring is a compression spring which pushes on the end of the pivot cap to bias a base of the pivot lock against an outer face of a first fork of the clevis. Pulling the pivot base disengages the star-shaped extrusion from the star-shaped aperture, causing the applicator head to be pivotable about a cylindrical pivot.
