Abstract: A hair treatment material applicator comprises a lid, a base, a hinge connecting the lid and base to allow pivotal movement of the lid and base with respect to each other from an open position to a closed position; and a bail pivotally mounted to the lid for pivotal movement from a use position above the lid to a latch position below the base holding the lid and base in the closed position. A compressible material, such as dense foam, is positioned in one of the lid and base; and a hair treatment material (such as highlighter, dye, bleach, protein treatment, etc.) is positioned in the other of the lid and base. The foam and material are positioned to allow strands of human hair to pass between them for uniform application of material to the strands. The hinge is an over-molded rubber hinge biasing the lid and base open.

Abstract: A magnetic closure includes a stationary first permanent magnet in a first housing member, a second movable permanent in a second housing member, and a stationary either ferromagnetic material or third permanent magnet in the first housing member. The second magnet is moved by an actuator (e. g. slides in a linear first dimension) to move between a first position in which it is attracted to the ferromagnetic material or third magnet to hold the housing members together, and a second position in which it repels the first magnet to separate the housing members. The housing members may define a cosmetics case.
