Abstract
A sandwich having a moisture containing bread base and a filler on top of said base enclosed in a nonmetallic film with means to accommodate selective heating in a controlled environment is provided with a conductive metallic layer between the bottom of the base and the nonmetallic film and is adapted for controlling a partial application of heat to the base relative to application of heat to the filler.
Claims15
In a system for heating a frozen sandwich including a nonmetallic film enclosing said sandwich, the combination which comprises:
- a. a conductive metallic layer placed over the inner bottom surface of said film and adapted for partial deflection of microwave energy applied to said film;
- b. a moisture containing bread base placed over said metallic layer;
- and
- c. A sandwich filler placed over said bread base.
A method of heating a frozen sandwich enclosed in a nonmetallic film and having a moisture containing bread base and a sandwich filler, which comprises:
- a. placing said filler on top of said bread base;
- b. hermetically sealing said filler and said bread base within said nonmetallic film;
- c. freezing said filler and said bread base;
- d. applying heat energy to said nonmetallic film;
- and
- e. partially shielding said bread base from said heat energy to provide a palatable food.
A system for heating a frozen sandwich enclosed in a nonmetallic film, said sandwich having a frozen bread base and a frozen filler on top of said base, which comprises:
- a. a conductive metallic layer between the bottom of said base and said nonmetallic film adapted for only partial application of microwave energy to said base relative to the application of said microwave energy to said filler;
- and
- b. a moisture absorbent layer interposed between said base and said metallic layer.
A method of heating a frozen sandwich enclosed in a nonmetallic film and having a moisture containing bread base and a filler on top of said base, which comprises:
- a. applying heating energy in a controlled environment in which said sandwich is placed;
- b. shielding said base for only partial application of heat to said base relative to the application of heat to said filler;
- and
- c. absorbing moisture which may be present in a zone immediately adjacent to said base.
A frozen food container, which comprises:
- a. a first wall of nonmetallic film;
- b. a second wall of nonmetallic film hermetically sealed to said first wall and including:
- i. an outer layer of nonmetallic film, and
- ii. an inner layer of nonmetallic film;
- c. a metallic layer interposed between said outer and said inner layers of said second wall for partially deflecting microwave energy directed therethrough;
- and
- d. a moisture absorbent layer placed over said inner layer of said second wall to absorb moisture which may collect adjacent to said metallic layer.
