Abstract
Abstract A portable appliance which includes a compartment for storing a plurality of hair rollers and an electrically energizable vapor generator cooperatively associated with the compartment to supply the compartment with hot vapor for heating and moistening the hair rollers. The floor of the compartment is inclined to cause the rollers to move, under the influence of gravity, through the compartment''s access opening to a platform from which the rollers may be successively removed. A well is located in the floor of the compartment beneath the level of the opening in the floor through which vapor from the vapor generator passes into the compartment. The condensate thus tends to flow to the well rather than enter the inlet opening. In addition, the structure which is provided for opening and closing the access opening includes apparatus for causing condensate to flow to the well, rather than exit the appliance.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
197 words
A portable appliance comprising: a. a compartment for storing a plurality of hair rollers, the compartment including a floor having a vapor inlet opening, the compartment including a cover above the floor and means connecting the cover and floor, the compartment having an access opening through which the rollers may be successively dispensed; b. an electrically energizable vapor generator cooperatively associated with the compartment for supplying hot vapor to the compartment via the inlet opening to heat and moisten the rollers; c. the floor having a portion extending beyond the cover to provide a platform from which a first roller may be removed, the floor having a well beneath the level of the inlet opening for collecting condensate; d. the floor oriented to cause a second roller to move through the access opening and onto the platform under the influence of gravity, in response to the first roller being removed from the platform; and e. closure means including means movably connected to the compartment for normally closing the access opening and holding rollers against movement to the platform, the movable means being movable for opening the access opening to release a roller for movement to the platform.

Claim 3
Dependent Claim
79 words
The appliance according to claim 1, wherein the floor is inclined at an angle with respect to the horizoNtal, the vapor generator has a vapor outlet extending upwardly from beneath the level of the bottom of the well to the inlet opening, and conduit means connecting the well and vapor generator in fluid flow communication with one another, whereby condensate from within the compartment normally flows to the well and thence to the vapor generator via the conduit means.
Claim 4
Dependent Claim
66 words
The appliance according to claim 2, wherein the vapor generator includes a refillable container, a heating element physically connected to the container, a heat fuse electrically connected in series combination with the heating element, and means for electrically connecting the series combination of the heating element and heat fuse to a source of supply of electricity for energizing the heating element and thus the vapor generator.
Claim 5
Dependent Claim
45 words
The appliance according to claim 1, wherein the closure means includes means for pivotally connecting the movable means to the compartment, and the movable means includes an elongated member extending across the access opening and over the platform, and means for manually moving the member.
Claim 6
Dependent Claim
28 words
The appliance according to claim 3, wherein the elongated member is L-shaped in transverse cross-section, and the connecting means connects one leg of the member to the compartment.
Claim 7
Dependent Claim
30 words
The appliance according to claim 5, wherein the member includes a ridge portion normally extending downwardly therefrom to cause condensate which collects on the member to flow to the well.
Claim 8
Dependent Claim
32 words
The appliance according to claim 4, wherein the elongated member is Z-shaped in transverse cross-section, and the connecting means connects one of the two free legs of the member to the compartment.
Claim 9
Dependent Claim
20 words
The appliance according to claim 1, wherein the closure means includes means causing condensate thereon to flow to the well.
Claim 10
Dependent Claim
24 words
The appliance according to claim 8, wherein the means causing condensate to flow to the well includes a ridge portion of the closure means.
Claim 11
Dependent Claim
16 words
The appliance according to claim 9, wherein the ridge portion has an apex normally pointing downwardly.
