Claim 3

The heat generating receptacle as claimed in claim claim 1, wherein one of the sections of the heat generating receptacle is the metallic main container and the another section is the metallic lid, the microwave oven irradiating microwaves onto the metallic lid at twice the strength of microwaves irradiated onto the metallic basin container, the microwaves are absorbing heat generating film layers being varied in thickness to be twice as thick on the metallic main container as on the metallic lid.

Claim 4

The heat generating receptacle as claimed in claim 2, wherein the microwave absorbing heat generating layers each have a thickness of 100 to 300 microns.

Claim 5

The heat generating receptacle as claimed in claim 2, wherein the microwave absorbing heat generating layers are a microwave absorbing heat generating paint solution including one of silicone, epoxy and polyester group containing 40 to 90% of iron oxide group ferrite powder.

Claim 6

A heat generating receptacle for use in a microwave oven, said microwave oven projecting microwaves onto the receptacle and said receptacle having different sections with at least one section receiving different amounts of microwaves than another section thereof, said heat generating receptacle comprising: a metallic main container; a detachable metallic lid for said metallic main container; microwave absorbing heat generating film layers form on an outer surface of said metallic main container and metallic lid, said microwave absorbing heat generating film layers having different thicknesses fro the different sections of the heat generating receptacle to thereby accommodate different amounts of microwaves received at the different sections of the heat generating receptacle for uniform heat generation of said main container and said lid; and a heat-resistant insulative packing disposed between said main container and said lid for closing said lid onto the main container.

Claim 7

A heat generating receptacle for use in a microwave oven, said microwave oven projecting microwaves onto the receptacle and said receptacle having different sections with at least one section receiving different amounts of microwaves than another section thereof, said heat generating receptacle comprising: a metallic main container; a detachable metallic lid for said metallic main container; microwave absorbing heat generating film layers form on an outer surface of said metallic main container and metallic lid, said microwave absorbing heat generating film layers having different thicknesses fro the different sections of the heat generating receptacle to thereby accommodate different amounts of microwaves received at the different sections of the heat generating receptacle for uniform heat generation of said main container and said lid; and a heat-resistant insulative packing disposed between said main container and said lid for closing said lid onto the main container.

Claim 8

The heat generating container as claimed in claim 5, wherein said heat-resistant insulative packing is made of silicone material.

Claim 9

A heat generating receptacle for use in a microwave oven comprising: a metallic main container; a detachable metallic lid for said metallic main container; microwave absorbing heat generating film layers formed on an outer surface of said metallic main container and metallic lid; rotary levers, each of said levers having a T-shaped cross section and being pivotally provided on an upper side wall of said main container; and engaging covers provided on an upper surface of said lid, said rotary levers being pivoted from a nonengaging position to a position in engagement with the engaging covers for releasably fixing said lid on said metallic main container, said rotary levers further being pivotable from the position in engagement with the engaging covers to the nonengaging position whereby said lid can be removed from the metallic main container, said heat generating container resisting internal forces therein from removing the lid fro the metallic main container when the rotary levers are in the engagement position nd the engaging covers being positioned between the rotary levers in the engagement position and the lid to thereby prevent direct contact o ht rotary levers and the microwave absorbing heat generating film layers on the metallic lid.

Claim 10

A heat generating receptacle for use in a microwave oven comprising: a metallic main container; a detachable metallic lid for said metallic main container; microwave absorbing heat generating film layers formed on an outer surface of said metallic main container and metallic lid; rotary levers, each of said levers having a T-shaped cross section and being pivotally provided on an upper side wall of said main container; and engaging covers provided on an upper surface of said lid, said rotary levers being pivoted from a nonengaging position to a position in engagement with the engaging covers for releasably fixing said lid on said metallic main container, said rotary levers further being pivotable from the position in engagement with the engaging covers to the nonengaging position whereby said lid can be removed from the metallic main container, said heat generating container resisting internal forces therein from removing the lid fro the metallic main container when the rotary levers are in the engagement position nd the engaging covers being positioned between the rotary levers in the engagement position and the lid to thereby prevent direct contact o ht rotary levers and the microwave absorbing heat generating film layers on the metallic lid.

Claim 11

The heat generating receptacle as claimed in claim 7, wherein the metallic main container and the lid have mating flange portions around the periphery thereof, the flange portion of the metallic main container being in engagement with the flange portion of the lid when the lid is on the metallic main cover to prevent microwaves fro entering the metallic main container, said engaging covers being located on the flange portion of the lid.

Claim 12

The heat generating receptacle as claimed in claim 7, wherein the rotary levers each have a stem portion and a top portion forming the T-shaped cross section, the stem portions being pivotally attached to the upper side wall of the main container and the top portions each having an inner and outer section, the inner sections engage the engaging covers when the rotary levers are in the engagement position and the outer sections then extend away from the lid to thereby provide handles for the heat generating receptacle.

Claim 13

The heat generating receptacle as claimed in claim 9, wherein each of the inner sections of the rotary levers has a protrusion thereon and wherein the engaging covers each have a raised detent, said protrusions of the inner sections being slid over the raised detents when the rotary levers are moved to the engagement position to thereby hod the rotary levers in the engagement position.

Claim 14

The heat generating receptacle as claimed in claim 7, wherein the rotary levers each have a protrusion thereon and wherein each of the engaging covers have a raised detent, said protrusions being slid over the raised detents when the rotary levers are moved to the engagement position to thereby hold the rotary levers int eh engagement position.
