Abstract

Abstract An hair treating implement comprises a pair of pivotally connected arms each comprising an operative section and a handle section. One arm section, which includes electric resistance heating means, provides an annular space containing an absorbent wick for receiving treatment liquid from a reservoir mounted in the handle section of the other arm, the flow of liquid being regulated by a manually operable push button valve. Said one arm section is perforated to allow the discharge of vaporized liquid.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 188 words
An implement for treating, regenerating and setting hair comprising a pair of hair engaging arms pivotally connected together, each arm having an operative section and a handle section, the operative section of one arm being of hollow cylindrical shape and the operative section of the other arm being shaped to match the shape of the operative section of said one arm, a hollow elongated container located inside the operative section of said one arm, electric resistance heating means located within said container, means for supplying electric current to said electric resistance heating means, an absorbent wick located between said container and the inside surface of the operative section of said one arm, a casing defining a reservoir for hair treating liquid mounted on the handle section of said other arm, means defining a passage for the flow of liquid from the reservoir to the absorbent wick and manually operable valve means mounted on the casing for controlling the flow of liquid from the reservoir to the wick, the operative section of said one arm being provided with perforations to allow the discharge of vaporized liquid from the wick.
Claim 2
Dependent Claim 188 words
An implement for treating, regenerating and setting hair comprising a pair of hair engaging arms pivotally connected together, each arm having an operative section and a handle section, the operative section of one arm being of hollow cylindrical shape and the operative section of the other arm being shaped to match the shape of the operative section of said one arm, a hollow elongated container located inside the operative section of said one arm, electric resistance heating means located within said container, means for supplying electric current to said electric resistance heating means, an absorbent wick located between said container and the inside surface of the operative section of said one arm, a casing defining a reservoir for hair treating liquid mounted on the handle section of said other arm, means defining a passage for the flow of liquid from the reservoir to the absorbent wick and manually operable valve means mounted on the casing for controlling the flow of liquid from the reservoir to the wick, the operative section of said one arm being provided with perforations to allow the discharge of vaporized liquid from the wick.
Claim 3
Dependent Claim 98 words
An implement according to claim 1, wherein the container is an elongated cylindrical tube closed at one end and open at the other end, the container being positioned relative to the operative section of said one arm so as to define an elongated space of crescent shaped cross section, the absorbent wick being located in said space, the container being sealed to the operative section of said one arm adjacent its open end thereby closing one end of the crescent-sectioned space and isolating the space from the interior of the container and the electric resistance heating means therein.
Claim 4
Dependent Claim 35 words
An implement according to claim 2, wherein the handle section of said other arm comprises a moulded casing attached to said other arm, the moulded casing defining a chamber wherein the reservoir casing is located.
Claim 5
Dependent Claim 53 words
An implement according to claim 3, wherein the operative section of said one arm is formed with an opening defining an inlet to said crescent-sectioned space, said passage for the flow of liquid being defined by a tubular nozzle depending from the reservoir casing and located by a flexible sealing surrounding said opening.
Claim 6
Dependent Claim 41 words
An implement according to claim 4, wherein the manually operable valve means comprises a spring-loaded push button projecting from the moulded casing operative to admit air to the reservoir casing to cause treatment liquid to flow through said passage under gravity.
Claim 7
Dependent Claim 31 words
An implement according to claim 3, wherein the operative section of said one arm is a cylindrical tube having a removable closure cap at the end remote from the handle section.
Claim 8
Dependent Claim 189 words
An implement for treating, regenerating and setting hair comprising a pair of hair engaging arms pivotally connected together, each arm having an operative section and a handle section, the operative section of one arm being of hollow cylindrical shape and the operative section of the other arm being shaped to match the shape of the operative section of said one arm, a hollow elongated container located inside the operative section of said one arm, electric resistance heating means located within said container, means for supplying electric current to said electric resistance heating means, an absorbent wick located between said container and the inside surface of the operative section of said one arm, a casing defining a reservoir for hair treating liquid carried by the handLe section of one of said arms, means defining a passage for the flow of liquid from the reservoir to the absorbent wick and manually operable valve means mounted on the casing for controlling the flow of liquid from the reservoir to the wick, the operative section of said one arm being provided with perforations to allow the discharge of vaporized liquid from the wick.
Claim 9
Dependent Claim 189 words
An implement for treating, regenerating and setting hair comprising a pair of hair engaging arms pivotally connected together, each arm having an operative section and a handle section, the operative section of one arm being of hollow cylindrical shape and the operative section of the other arm being shaped to match the shape of the operative section of said one arm, a hollow elongated container located inside the operative section of said one arm, electric resistance heating means located within said container, means for supplying electric current to said electric resistance heating means, an absorbent wick located between said container and the inside surface of the operative section of said one arm, a casing defining a reservoir for hair treating liquid carried by the handLe section of one of said arms, means defining a passage for the flow of liquid from the reservoir to the absorbent wick and manually operable valve means mounted on the casing for controlling the flow of liquid from the reservoir to the wick, the operative section of said one arm being provided with perforations to allow the discharge of vaporized liquid from the wick.
