Abstract
A molded cosmetic applicator head having a core that supports an array of semi-conical bristles arranged in rows and columns, such that the surfaces of the bristles assume certain orientations, and wherein at least some of the bristles have at one or more prominent depressions and/or prominent protrusions located on a curved surface. A mold for an injection molded applicator head is also described.
Claims16
A molded cosmetic applicator head comprising:
- a core having a longitudinal axis, and
- an array of bristles projecting from the core, arranged in rows and columns, wherein:
- each bristle comprises a flat surface that extends the height of the bristle, and a rounded surface;
- within each column of bristles, all of the flat surfaces lie in the same plane and are parallel to the longitudinal axis of the core;
- within each row of bristles, the flat surfaces of adjacent bristles are oriented to each other at an angle γ=360°/M degrees, where M is the number of columns;
- and
- one or more prominent depressions and/or prominent protrusions are located on the rounded surfaces of at least some of the bristles, but not on the flat surfaces of any of the bristles.
4 more elements
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 are regularly arranged in M columns that extends down the core space, parallel to the longitudinal axis;
