主权项

1. A mold for an injection molded applicator head comprising a number, M, of separable mold sections that when assembled, define a mold cavity, wherein
each mold section fills an angle of 360°/M; each mold section comprises an interior face, a flat lateral face, and a sculpted lateral face; the interior faces define a core space that has a longitudinal axis that extends along the length of the core space; the sculpted lateral faces are flat except for number of bristle spaces cut into them, such that the bristle spaces extend radially from the core space, and are regularly arranged in M columns that extend down the core space, parallel to the longitudinal axis; and the flat lateral faces of adjacent mold sections are oriented to each other at an angle γ=360°/M degrees.
