Abstract
Abstract An apparatus for steaming food is disclosed. Food suspended within a compartment of the apparatus is cooked by steam rising from a reservoir of boiling water below. After passing through the food compartment, steam collects in a dome shaped lid where it condenses to water then which flows by means of a gutter device below the lid into channels along the food compartment walls to return to the reservoir without contacting the food.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
185 words
An apparatus for cooking food with steam, comprising: a base compartment having a bottom and substantially vertical sides to contain water; a food compartment supported by said base compartment having a bottom which is perforated, a lower section inside said base compartment, substantially vertical sidewalls, a top, and an upper section outside of said base compartment and above said base compartment; a lid on the top of said food compartment to trap and condense water vapor above said food compartment; at least one enclosed channel in said side wall of said food compartment having a first open end at the top of the upper section of said food compartment and second open end at the bottom of said lower section; a gutter near the top of said food compartment to collect condensed water vapor from said lid and divert it into said first open end of said channel, said channel and said gutter acting together to transfer condensed water vapor from said lid to said base compartment, thereby avoiding contact of said condensed water vapor with food, wherein said gutter is affixed to said lid.
Claim 2
Independent Claim
185 words
An apparatus for cooking food with steam, comprising: a base compartment having a bottom and substantially vertical sides to contain water; a food compartment supported by said base compartment having a bottom which is perforated, a lower section inside said base compartment, substantially vertical sidewalls, a top, and an upper section outside of said base compartment and above said base compartment; a lid on the top of said food compartment to trap and condense water vapor above said food compartment; at least one enclosed channel in said side wall of said food compartment having a first open end at the top of the upper section of said food compartment and second open end at the bottom of said lower section; a gutter near the top of said food compartment to collect condensed water vapor from said lid and divert it into said first open end of said channel, said channel and said gutter acting together to transfer condensed water vapor from said lid to said base compartment, thereby avoiding contact of said condensed water vapor with food, wherein said gutter is affixed to said lid.
Claim 3
Independent Claim
216 words
An apparatus for cooking food with steam, comprising: a base compartment having a bottom and substantially vertical sides to contain water; a food compartment supported by said base compartment having a bottom which is perforated, a lower section inside said base compartment, substantially vertical sidewalls, a top, and an upper section outside of said base compartment and above said base compartment; a lid on the top of said food compartment to trap and condense water vapor above said food compartment; at least one enclosed channel in said side wall of said food compartment having a first open end at the top of the upper section of said food compartment and a second open end at the bottom of said lower section; a gutter near the top of said food compartment to collect condensed water vapor from said lid and divert it into said first open end of said channel, said channel and said gutter acting together to transfer condensed water vapor from said lid to said base compartment, thereby avoiding contact of said condensed water vapor with food, wherein said gutter is a substantially horizontal strip lying beneath said lid having at least one aperture therethrough, having an outer edge in contact with the periphery of the lid, and an inner edge bearing a vertical lip.
Claim 4
Independent Claim
216 words
An apparatus for cooking food with steam, comprising: a base compartment having a bottom and substantially vertical sides to contain water; a food compartment supported by said base compartment having a bottom which is perforated, a lower section inside said base compartment, substantially vertical sidewalls, a top, and an upper section outside of said base compartment and above said base compartment; a lid on the top of said food compartment to trap and condense water vapor above said food compartment; at least one enclosed channel in said side wall of said food compartment having a first open end at the top of the upper section of said food compartment and a second open end at the bottom of said lower section; a gutter near the top of said food compartment to collect condensed water vapor from said lid and divert it into said first open end of said channel, said channel and said gutter acting together to transfer condensed water vapor from said lid to said base compartment, thereby avoiding contact of said condensed water vapor with food, wherein said gutter is a substantially horizontal strip lying beneath said lid having at least one aperture therethrough, having an outer edge in contact with the periphery of the lid, and an inner edge bearing a vertical lip.
Claim 5
Dependent Claim
26 words
An apparatus according to claim 2, further comprising a tray having a perforated bottom, said tray being seated within said upper section of said food compartment.
Claim 6
Independent Claim
21 words
An apparatus according to claims 2 or 3, wherein said base compartment and said food compartment are substantially cylindrical in shape.
Claim 7
Independent Claim
25 words
An apparatus according to claims 2 or 3, wherein the bottom of said base compartment comprises two layers of material spaced apart from each other.
Claim 8
Dependent Claim
27 words
An apparatus according to claim 3, wherein the perforations in said bottom of said tray are smaller than the perforations in said bottom of said food compartment.
Claim 9
Dependent Claim
16 words
An apparatus according to claim 2 or 3, wherein said gutter is affixed to said lid.
Claim 10
Dependent Claim
13 words
An apparatus according to claim 2 or 3, wherein said lid is dome-shaped.
Claim 11
Dependent Claim
25 words
An apparatus according to claim 2 or 3, further comprising a mechanical index to facilitate alignment of said aperture in said gutter with said channel.
