Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
199 words
A pliable and flexible oven for heating food and the like comprising a pliable and flexible waterproof, reflective inside wall wherethrough heat can be conducted; a pliable and flexible outside wall secured to said inside wall, said inside and outside walls being secured to each other such as to form a front outer cover, a rear outer cover, and an intermediate cover strip secured to said front outer cover, to said rear outer cover in order to form a pair of ends and a bottom and an opening communicating with the inside wall, said rear outer cover extending beyond said opening to define a cover flap that is adaptable to generally close said opening; a fastening means secured to said cover flap and to said front outer cover for sealing the opening to totally enclose any food that has been disposed through the opening and resting on the waterproof, reflective inside wall; and a pliable and flexible heating element means for heating food resting on the inside wall, said heating element means disposed between the inside and outside wall and extending through the outside wall to communicate with a power source, said waterproof, reflective inside wall comprising polyethylene terephthalate.
Claim 2
Dependent Claim
199 words
A pliable and flexible oven for heating food and the like comprising a pliable and flexible waterproof, reflective inside wall wherethrough heat can be conducted; a pliable and flexible outside wall secured to said inside wall, said inside and outside walls being secured to each other such as to form a front outer cover, a rear outer cover, and an intermediate cover strip secured to said front outer cover, to said rear outer cover in order to form a pair of ends and a bottom and an opening communicating with the inside wall, said rear outer cover extending beyond said opening to define a cover flap that is adaptable to generally close said opening; a fastening means secured to said cover flap and to said front outer cover for sealing the opening to totally enclose any food that has been disposed through the opening and resting on the waterproof, reflective inside wall; and a pliable and flexible heating element means for heating food resting on the inside wall, said heating element means disposed between the inside and outside wall and extending through the outside wall to communicate with a power source, said waterproof, reflective inside wall comprising polyethylene terephthalate.
