Abstract
Abstract An applicator for applying hair treatment preparations to a person's hair and for rinsing the preparation from the hair. The applicator is a compact device which includes a remotely located heater/blower unit coupled to a hand-held applicator assembly. The applicator assembly includes a chamber for receipt of a viscous hair treatment preparation and a plurality of apertured projections which communicate with the chamber. A stream of heated air is provided into the chamber, to melt the preparation. The melted preparation flows from the chamber, through the apertures and onto the person's hair. The projections function as comb teeth to spread the preparation through the hair. The applicator assembly can be connected to a water tap, for water to flow through the apertures of the applicator assembly so the preparation may simultaneously be rinsed and combed from a person's hair. The preferred embodiment of the invention includes a removable scoop and capsule member. The scoop is readily filled with the preparation and is inserted into the capsule. The scoop and capsule assembly is then inserted into the chamber of the applicator assembly, thus facilitating the process of filling the chamber with the preparation.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
258 words
A compact device for applying a hair treatment preparation liquid to hair comprising an applicator assembly and remotely located means for producing a stream of heated air and for supplying said air stream through flexible conduit means to said applicator assembly, said applicator assembly being readily manipulatable and comprising a hand grasping portion and a body portion, said body portion including a dispensing chamber, said dispensing chamber including an access port, replaceable capsule means and filter means, said access port enabling the insertion and removal, respectively of said capsule means from said chamber, said capsule means being hollow for receipt of a mass of viscous hair treatment liquid preparation and having at least one dispensing aperture and an inlet opening communicating with the interior of said capsule means, said filter means being coupled between said inlet opening and said conduit means for allowing said heated air to pass therethrough while precluding said preparation liquid from passing therethrough, said body portion also comprising a plurality of teeth in the form of hollow tubular projections extending outward from said body portion, the interior of each of said teeth being in communication with the interior of said capsule means and each of said teeth including at least one dispensing aperture, said dispensing chamber receiving said heated air stream from said conduit means whereupon said heated air passes through said filter means, into said capsule means to cause said viscous liquid to melt within said capsule means and to flow thereout through the dispensing apertures in said teeth for application to hair.
