Abstract
Abstract A cover or lid for a vessel designed for cooking or heating liquids and mixtures of liquids and solids which has means adapted both to vent vapor and noncondensible gases from the cooking or heating vessel and to permit additional liquid to be passed into the cooking or heating vessel without the necessity of removing the cover from the vessel. The cover or lid also is constructed to coact with the venting and transport means to condense vapors and return the liquid condensed to the liquid or mixture being cooked, heated or fried in the vessel. The cover or lid may consist of an annular rim section and a middle section. The middle section can be transparent and can be integral with, separable from or detachably connected to the annular rim section of the cover or lid. Additionally, the cover or lid with the transparent middle section may coact with a wiping means for cleaning the inner face of this section.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
207 words
A utensil lid for a heating, cooking or frying vessel comprising: a. a platelike member including a centrally disposed domed portion, means forming an annular reservoir connected to the inner side adjacent to the peripheral part of the domed portion and an annular portion connected to the outer side of the annular reservoir means remote from the domed portion; b. said annular reservoir means extending below said annular portion and the peripheral portion of the domed portion of the platelike member and having at least one curved wall and at least one wall normal to a horizontal plane through the platelike member; c. said curved wall shaped with a radius of curvature continuous with the domed portion of the platelike member and connected to the lower end of said normal wall whereby the domed portion and the curved wall provide a condensing surface for vapors and means to return condensed vapor to the associated vessel; d. said normal wall at the upper end connected to the annular portion a spaced distance inward from the peripheral edge thereof; e. and said annular reservoir means having fluid transport and venting means to permit liquid to be passed therethrough and to pass vapors and noncondensible gases from the associated vessel.
Claim 2
Dependent Claim
207 words
A utensil lid for a heating, cooking or frying vessel comprising: a. a platelike member including a centrally disposed domed portion, means forming an annular reservoir connected to the inner side adjacent to the peripheral part of the domed portion and an annular portion connected to the outer side of the annular reservoir means remote from the domed portion; b. said annular reservoir means extending below said annular portion and the peripheral portion of the domed portion of the platelike member and having at least one curved wall and at least one wall normal to a horizontal plane through the platelike member; c. said curved wall shaped with a radius of curvature continuous with the domed portion of the platelike member and connected to the lower end of said normal wall whereby the domed portion and the curved wall provide a condensing surface for vapors and means to return condensed vapor to the associated vessel; d. said normal wall at the upper end connected to the annular portion a spaced distance inward from the peripheral edge thereof; e. and said annular reservoir means having fluid transport and venting means to permit liquid to be passed therethrough and to pass vapors and noncondensible gases from the associated vessel.
Claim 3
Dependent Claim
43 words
In a utensil lid as claimed in claim 1 wherein the spaced distance the normal wall is connected inward of the periphery of the annular portion of the platelike member is in an optimum range for the given diameter of the utensil lid.
Claim 4
Dependent Claim
37 words
In a utensil lid as claimed in claim 2 wherein said normal wall is spaced in assembled position for operative relation with the sidewall of the associated vessel to prevent escape of spattering liquids from the vessel.
Claim 5
Dependent Claim
34 words
In a utensil lid as claimed in claim 1 including a shield means connected to said utensil lid adjacent the fluid transport and venting means to present spattered liquid from escaping from said vessel.
Claim 6
Dependent Claim
16 words
In a utensil lid as claimed in claim 1 wherein an optically transparent section is provided.
Claim 7
Dependent Claim
18 words
In a utensil lid as claimed in claim 1 wherein the centrally disposed domed portion is optically transparent.
Claim 8
Dependent Claim
59 words
In a utensil lid as claimed in claim 6, including: a. wiping means detachably connected to said utensil lid, b. a wiping element on said wiping means in engagement with the undersurface of the optically transparent centrally disposed domed portion, c. and means for operating said wiping means when said utensil lid is in operating position on said vessel.
Claim 9
Dependent Claim
21 words
In a utensil lid as claimed in claim 6, wherein said annular portion is detachably connected to said centrally domed portion.
Claim 10
Dependent Claim
46 words
In a utensil lid as claimed in claim 6, wherein said annular portion has said normal wall formed therein and said centrally domed portion has said curved wall formed thereon, and means on said normal wall to detachably connect said domed portion to said annular portion.
Claim 11
Dependent Claim
49 words
In a utensil lid as claimed in claim 9 wherein the detachable connecting means includes a plurality of spaced catch members, and said catch members are disposed to hold the domed portion in predetermined position on said normal wall for suitable coaction with said fluid transport and venting means.
Claim 12
Dependent Claim
55 words
In a utensil lid as claimed in claim 6 wherein said means forming the annular reservoir is connected to said domed portion and: a. means forming a peripheral edge in said domed portion about said annular reservoir, b. connecting means on said annular portion to engage and hold said peripheral edge of said domed portion.
Claim 13
Dependent Claim
130 words
In a utensil lid for a heating, cooking and frying vessel comprising: a. a platelike member including an annular rim section, and a transparent central section. b. means forming an annular reservoir connected to the inner side of the transparent central section, c. means connecting the annular rim section to the annular reservoir means on the side remote from the inner side of the annular reservoir, d. said annular reservoir means extending below said annular portion and the adjacent portion of the transparent central section and having fluid transport and venting means to permit liquid to be passed therethrough and to pass vapors and noncondensible gases when in operating position on said vessel, e. and said connecting means is disposed on the annular rim section adjacent said annular reservoir means.
Claim 14
Dependent Claim
130 words
In a utensil lid for a heating, cooking and frying vessel comprising: a. a platelike member including an annular rim section, and a transparent central section. b. means forming an annular reservoir connected to the inner side of the transparent central section, c. means connecting the annular rim section to the annular reservoir means on the side remote from the inner side of the annular reservoir, d. said annular reservoir means extending below said annular portion and the adjacent portion of the transparent central section and having fluid transport and venting means to permit liquid to be passed therethrough and to pass vapors and noncondensible gases when in operating position on said vessel, e. and said connecting means is disposed on the annular rim section adjacent said annular reservoir means.
Claim 15
Dependent Claim
