Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
A heat storage dish comprising a central heat storage plate, means defining an insulation member surrounding said heat storage plate, means effective during stacking of a plurality of said heat storage dishes for establishing heat transfer relationship between the heat storage plates of adjacently stacked heat storage dishes, said effective means essentially provides heat conducting contact between the heat storage plates of adjacently stacked heat storage dishes, said insulation member including downwardly sloping inner wall means extending towards the heat storage plate surrounded by said insulation member, said heat storage plate possessing an upper surface at least part of which protrudes upwardly away from the lowermost location of said downwardly sloping inner wall means, said heat storage plate further including a lower surface extending downwardly past said lowermost location of said downwardly sloping inner wall means.
Claim 2
Dependent Claim
136 words
A heat storage dish comprising a central heat storage plate, means defining an insulation member surrounding said heat storage plate, means effective during stacking of a plurality of said heat storage dishes for establishing heat transfer relationship between the heat storage plates of adjacently stacked heat storage dishes, said effective means essentially provides heat conducting contact between the heat storage plates of adjacently stacked heat storage dishes, said insulation member including downwardly sloping inner wall means extending towards the heat storage plate surrounded by said insulation member, said heat storage plate possessing an upper surface at least part of which protrudes upwardly away from the lowermost location of said downwardly sloping inner wall means, said heat storage plate further including a lower surface extending downwardly past said lowermost location of said downwardly sloping inner wall means.
Claim 3
Dependent Claim
94 words
The heat storage dish as defined in claim 1, wherein each heat storage plate comprises an upper surface and a lower surface, said effective means comprises depression means for receiving at least part of said insulation member of an overlying adjacent stacked heat storage dish, so that at least a portion of the lower surface of the heat storage plate of said overlying adjacent stacked heat storage dish comes into heat conducting contact with at least a portion of the upper surface of the heat storage plate of the lower situated heat storage dish.
Claim 4
Dependent Claim
39 words
The heat storage dish as defined in claim 2, wherein said depression means comprises a continuous groove of sufficient depth to permit reception of at least part of the under surface of said overlying adjacent stacked heat storage dish.
Claim 5
Dependent Claim
34 words
The heat storage dish as defined in claim 3, wherein said continuous groove is located at an outer circumferential surface of the heat storage plate and an adjacent neighboring portion of said insulation member.
Claim 6
Dependent Claim
74 words
The heat storage dish as defined in claim 1, wherein said insulation member further includes a downwardly sloping outer wall means including a supporting portion, said heat storage plate including a downwardly protruding portion defining at least a portion of the lower surface of said heat storage plate, said downwardly protruding portion extending in close proximity to a plane intersecting said supporting portion of the downwardly sloping outer wall means of the insulation member.
Claim 7
Dependent Claim
28 words
The heat storage dish as defined in claim 5, wherein the downwardly protruding portion is spaced from said plane in the order of about 2 to 4 millimeters.
Claim 8
Dependent Claim
44 words
The heat storage dish as defined in claim 1, wherein said insulation member includes a portion engaging beneath a part of the under surface of the heat storage plate to protect the user against contact with the marginal region of said heat storage plate.
Claim 9
Dependent Claim
32 words
The heat storage dish as defined in claim 1, wherein said heat storage plate is provided with an opening capable of receiving a heating element for heating the heat storage plate thereof.
Claim 10
Dependent Claim
18 words
The heat storage dish as defined in claim 8, wherein said heat storage plate can be inductively heated.
Claim 11
Dependent Claim
19 words
The heat storage dish as defined in claim 1, wherein said heat storage plate is a solid body member.
Claim 12
Dependent Claim
18 words
The heat storage dish as defined in claim 10, wherein said solid body member can be inductively heated.
