Abstract

Abstract A microwave cooking vessel is formed of two bowl sections, either of which may be the top, and both of which have peripheral lips. The sections interfit through congruent upstanding rims, the outer one of which rests upon the lip of the other bowl, thus creating spacing between the lips. Pairs of lip extensions at the ends, spaced as above, serve as handles. Raised, interfitting circular ridges on the top and bottom of the bowls permit stacking of vessels and permit one bowl to act as a trivet for the other.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 259 words
A reversible, two-section microwave cooking vessel capable of being used with either section on the base and the other section as the top, with the two sections interfitting, said vessel including a first bowl and a second bowl made of material which is transparent to microwaves, said first bowl having a larger volumetric capacity than said second bowl, said bowls being of generally similar shape, each of said bowls having a vertical upstanding rim along the inner edge of the periphery thereof, said rims being complementary and interfitting, with said rim of said first bowl fitting outside the said rim of said second bowl, horizontal peripheral lips on each said bowl, said lips being proximate to, but spaced from, said rims on their respective said bowls, and the outer of said rims of one said bowl resting on the lip of the other said bowl when said bowls are assembled and thereby spacing said lips from one another, said lips defining pairs of handle extensions at opposite ends of said bowls and being so spaced from one another when said bowls are interfitted as to permit grasping said pairs between thumb and forefinger of one's hands and far enough apart to permit a finger to come between them to separate said bowls, and a probe hole in said rims, said probe hole being aligned in said rims of said bowls and being midway between said pairs of handle extensions at said opposite ends of said bowls, whereby said lips together define spaced handle extensions when said bowls are assembled.
Claim 2
Dependent Claim 259 words
A reversible, two-section microwave cooking vessel capable of being used with either section on the base and the other section as the top, with the two sections interfitting, said vessel including a first bowl and a second bowl made of material which is transparent to microwaves, said first bowl having a larger volumetric capacity than said second bowl, said bowls being of generally similar shape, each of said bowls having a vertical upstanding rim along the inner edge of the periphery thereof, said rims being complementary and interfitting, with said rim of said first bowl fitting outside the said rim of said second bowl, horizontal peripheral lips on each said bowl, said lips being proximate to, but spaced from, said rims on their respective said bowls, and the outer of said rims of one said bowl resting on the lip of the other said bowl when said bowls are assembled and thereby spacing said lips from one another, said lips defining pairs of handle extensions at opposite ends of said bowls and being so spaced from one another when said bowls are interfitted as to permit grasping said pairs between thumb and forefinger of one's hands and far enough apart to permit a finger to come between them to separate said bowls, and a probe hole in said rims, said probe hole being aligned in said rims of said bowls and being midway between said pairs of handle extensions at said opposite ends of said bowls, whereby said lips together define spaced handle extensions when said bowls are assembled.
Claim 3
Dependent Claim 265 words
A reversible microwave cooking vessel capable of being used with either section as the base and the other section as the top, with the two sections interfitting, said vessel including a first bowl and a second bowl made of material which is transparent to microwaves, said bowls being of generally semi-cylindrical shape, each of said bowls having a vertical upstanding rim along the inner edge of the periphery thereof, said rims being complementary and interfitting with said rim of said first bowl fitting outside the said rim of said second bowl, and the inner surface of said rims forming a smooth surface with the inner surface of its respective said bowl, each of said rims having a probe hole therein, said probe holes being aligned to form a single hole, and a pair of handle extensions on each said bowl, the extensions of each said pair extending from opposite sides of their respective said bowls and being about ninety degrees removed from said probe hole on each said bowl, and said rib of said first bowl fitting against said handle extension of said second bowl, said handle extensions being so spaced from the periphery of said bowls as to be close enough together when said bowls are interfitted as to permit grasping said pairs between thumb and forefinger of one's two hands and far enough apart to permit a finger to come between them to separate said bowls, whereby said bowls may be used reversibly with one on the bottom to hold food during cooking and/or serving and the other to act as a cover.
Claim 4
Dependent Claim 265 words
A reversible microwave cooking vessel capable of being used with either section as the base and the other section as the top, with the two sections interfitting, said vessel including a first bowl and a second bowl made of material which is transparent to microwaves, said bowls being of generally semi-cylindrical shape, each of said bowls having a vertical upstanding rim along the inner edge of the periphery thereof, said rims being complementary and interfitting with said rim of said first bowl fitting outside the said rim of said second bowl, and the inner surface of said rims forming a smooth surface with the inner surface of its respective said bowl, each of said rims having a probe hole therein, said probe holes being aligned to form a single hole, and a pair of handle extensions on each said bowl, the extensions of each said pair extending from opposite sides of their respective said bowls and being about ninety degrees removed from said probe hole on each said bowl, and said rib of said first bowl fitting against said handle extension of said second bowl, said handle extensions being so spaced from the periphery of said bowls as to be close enough together when said bowls are interfitted as to permit grasping said pairs between thumb and forefinger of one's two hands and far enough apart to permit a finger to come between them to separate said bowls, whereby said bowls may be used reversibly with one on the bottom to hold food during cooking and/or serving and the other to act as a cover.
