Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
61 words
A glazed article, which is generally flat and is produced by firing in a kiln, having inner and outer foot-rings that protrude from its underside and have their bottom surfaces at upper and lower horizontal levels when the article is disposed horizontally, and wherein only the foot-ring having its bottom surface at the upper level is glazed on its bottom surface.
Claim 2
Dependent Claim
61 words
A glazed article, which is generally flat and is produced by firing in a kiln, having inner and outer foot-rings that protrude from its underside and have their bottom surfaces at upper and lower horizontal levels when the article is disposed horizontally, and wherein only the foot-ring having its bottom surface at the upper level is glazed on its bottom surface.
Claim 3
Dependent Claim
11 words
An article according to claim 1, wherein the foot-rings are concentric.
Claim 4
Dependent Claim
21 words
An article according to claim 1, wherein the outer and inner foot-rings have essentially the same general outline as the article.
Claim 5
Dependent Claim
18 words
An article according to claim 3, wherein the article is substantially circular and the foot-rings are substantially circular.
Claim 6
Dependent Claim
23 words
An article according to claim 4, wherein the inner foot-ring has a diameter of 45% to 70% of the diameter of the article.
Claim 7
Dependent Claim
23 words
An article according to claim 4, wherein the outer foot-ring has a diameter of 65% to 85% of the diameter of the article.
Claim 8
Dependent Claim
24 words
An article according to claim 4, wherein the distance between the inner and outer foot-rings is 7% to 15% the diameter of the article.
Claim 9
Dependent Claim
44 words
An article according to claim 1, wherein the inner foot-ring has its bottom surface at a lower level than the bottom surface of the outer foot-ring, so that when the article is standing on a flat surface, only the inner foot-ring touches the surface.
Claim 10
Dependent Claim
33 words
An article according to claim 8, wherein the upper surface of the article is so formed that when the article stands on another similar article, only the outer foot-ring touches the article beneath.
Claim 11
Dependent Claim
65 words
An article according to claim 8, wherein the article has a step on its upper surface, said step having essentially the same general outline as the outer foot-ring and being slightly larger than the outer foot-ring, so that when two similar articles are placed one on top of the other, the outer foot-ring of the upper article engages in the step of the article beneath.
Claim 12
Dependent Claim
31 words
An article according to claim 10, wherein said step is one side of a groove that receives the outer foot-ring of the article above, when one article is standing on another.
Claim 13
Dependent Claim
52 words
An article according to claim 8, wherein the article is so shaped that, when it is drawn across another similar article beneath it, substantially all contact between the upper article and the article beneath takes place between the outer foot-ring of the upper article and the upper surface of the article beneath.
Claim 14
Dependent Claim
51 words
A glazed ceramic dinner plate having inner and outer foot-rings that protrude from its underside and have their bottom surfaces at upper and lower horizontal levels when the plate is disposed horizontally, and wherein only the foot-ring having its bottom surface at the upper level is glazed on its bottom surface.
Claim 15
Dependent Claim
51 words
A glazed ceramic dinner plate having inner and outer foot-rings that protrude from its underside and have their bottom surfaces at upper and lower horizontal levels when the plate is disposed horizontally, and wherein only the foot-ring having its bottom surface at the upper level is glazed on its bottom surface.
Claim 16
Dependent Claim
22 words
A plate according to claim 13, being substantially circular, and wherein the foot-rings are substantially circular and substantially concentric with the plate.
Claim 17
Dependent Claim
58 words
A plate according to claim 14, wherein the inner foot-ring has a diameter of 45% to 70% of the diameter of the plate, the outer foot-ring has a diameter of 65% to 85% of the diameter of the plate, and the radial distance between the inner and outer foot-rings is 7% to 15% the diameter of the plate.
Claim 18
Dependent Claim
44 words
A plate according to claim 13, wherein the inner foot-ring has its bottom surface at a lower level than the bottom surface of the outer foot-ring, so that when the plate is standing on a flat surface, only the inner foot-ring touches the surface.
Claim 19
Dependent Claim
27 words
A plate according to claim 16, being so formed that when the plate stands concentrically on another similar plate, only the outer foot-ring touches the plate beneath.
Claim 20
Dependent Claim
65 words
A plate according to claim 16, being formed with a step on its upper surface, said step having essentially the same general outline as the outer foot-ring and being slightly larger than the outer foot-ring, so that when two similar plates are placed concentrically one on top of the other, the outer foot-ring of the upper plate engages in the step of the plate beneath.
Claim 21
Dependent Claim
32 words
A plate according to claim 18, wherein said step is one side of a groove that receives the outer foot-ring of the plate above, when one plate is placed concentrically on another.
Claim 22
Dependent Claim

Claim 23
Independent Claim
104 words
A method of manufacturing a glazed ceramic flatware plate comprising: forming a plate of ceramic material in the unfired state, the plate having inner and outer foot-rings that protrude from its underside and have their bottom surfaces at upper and lower horizontal levels when the plate is horizontal, applying glaze to the plate in a manner such that the foot-ring bottom surface at the upper horizontal level is glazed but the foot-ring bottom surface at the lower horizontal level is not glazed, and firing the plate while supporting it on a surface in contact with the foot-ring bottom surface at the lower horizontal level.
