Abstract: A capsule for containing a chemical coloring agent as it treats a lock of hair has a male side with a projection and a female side with a cavity, connected by a hinge that allows the projection and the cavity to be swung into sealing relationship with the hair trapped therebetween. A reinforcing pattern of interconnected elements form a region of one of the surfaces, the pattern forming an array of spaced-apart islands. The interconnected elements provide enhanced rigidity for the capsule and provide the capsule a better grip on the hair to maintain the capsule in place. The male side and/or female side may be provided with a trough positioned opposite the hinge to reduce overflow of the coloring agent, and can be provided with a well positioned near the hinge to allow the hair to more readily distribute itself when folded over.

Abstract: The present invention is directed to a hair highlighting capsule which confines the hair and the coloring solution for a time sufficient to effect the desired coloration of the hair. The hair highlighting capsule is preferably transparent so that the stylist can observe the process. The capsule of the present invention is reusable and easily sealable. The hair highlighting capsule has a female side which is provided with a central cavity and a male side which is provided with a projection. The projection is contoured to be accepted by the central cavity. The depth of the cavity and mating projection are preferably about 0.125 inches. A hinge connects the female side and the male side and is positioned so that the projection and central cavity will register when the capsule is closed. The capsule is sealed by locking the projection into the central cavity. The seal limits flow of the chemical coloring solution from the capsule and excludes the flow of water and other fluids into the capsule.
