Abstract

A pneumatic hairbrush for people and pets releases a powder mixture containing perfume, fragrance and/or other active compositions directly onto the hair or fur during brushing. Delivery of the powder mixture is activated during brushing or through manually depressing the brushes cover. The powder mixture contains perfumes, fragrances and/or other active compositions including insect repellant, shampoo, hair conditioning composition, dye composition, moisturizing ingredients, or antibacterial compounds. The brush includes a flexible deformable membrane that carries brush bristles and has a plurality of apertures for delivery of the active composition and is fitted within a first opening of an internal cavity in a brush base. The powder mixture containing the active ingredient is poured into the internal cavity and disseminates over the flexible deformable membrane. A cover is inserted through a second opening. Brushing action deforms the flexible deformable membrane and compresses the internal cavity causing the powder mixture to be pneumatically forced within the plurality of apertures of the brush bristles into direct contact with the skin of an animal, or around the outside surfaces of the bristles, and released. Manually depressing the cover also pneumatically forces the powder mixture to be released, even though the bristles may not be in direct contact with the hair at that time.

Claims

1. A hairbrush for humans and pets, comprising:

a. a brush base with a handle and an internal cavity having a cavity area with a bottom surface having a first opening and top surface having a second opening, respectively;
