Microwave heating digestion vessel

Claim 2

A microwave heating digestion vessel for use in microwave oven during a microwave heating digestion of a material comprising: a. a molded threaded vessel with threads at an upper end of said vessel for holding at least one material for a microwave heating digestion; b. a mating molded threaded cap for covering said vessel, said vessel and said cap being transparent to microwave energy, said cap including a plunger seat in a cylindrical member affixed to a top of said cap, a downwardly extending hole through said cylindrical member and said cap about said plunger seat and a side hole extending through said cylindrical member slightly above said plunger seat, and threads surrounding an upper portion of said cylindrical member; c. an adjustable nut including inner threads on a lower portion thereof for engaging said threads of said cylindrical member, a configured diaphragm seat extending across a mid-portion of said nut and a plunger extending downwardly therefrom for engaging in said plunger seat in a nonpressure state; and, d. a diaphragm being transparent to microwave energy engaged in said adjustable nut in said diaphragm seat whereby pressure during a microwave heating digestion in said vessel causes said plunger to move upwardly against said diaphragm in said diaphragm seat and pass gases and liquids through said downwardly extending hole, about said plunger seat and through said side hole.

Claim 3

Vessel of claim 1 wherein said vessel, said cap and said plunger are of polymer material.

Claim 4

Vessel of claim 1 wherein said adjustable nut includes a plunger insert of a material transparent to microwave energy.

Claim 5

Vessel of claim 1 wherein said plunger includes a shaft and at least one O ring about said shaft.

Claim 6

Vessel of claim 1 wherein said plunger includes at least one sealing ring about a circumference of said plunger.

Claim 7

Vessel of claim 1 wherein said adjustable nut includes a flexible area adjacent to said plunger.

Claim 8

Vessel of claim 1 wherein said diaphragm includes a varying thickness to enhance spring action.

Claim 9

Vessel of claim 1 wherein said diaphragm is of polymer material.

Claim 10

Vessel of claim 1 wherein said vessel includes a plurality of vertical ribs to enhance the strength of said vessel.

Claim 11

Vessel of claim 1 wherein said adjustable nut includes means for pressure release in said vessel.

Claim 12

Vessel of claim 1 wherein said diaphragm includes means for retaining said diaphragm in said nut and at least one horizontal retaining barb about said retaining means.

Claim 13

A microwave heating digestion vessel for use in microwave oven during a microwave heating digestion of a material comprising: a. a molded threaded vessel with threads at an upper end of said vessel for holding at least one material for a microwave heating digestion; b. a mating molded threaded cap for covering said vessel, said vessel and said cap being transparent to microwave energy, said cap including a plunger seat in a cylindrical member affixed to a top of said cap, a downwardly extending hole through said cylindrical member and said cap about said plunger seat and a side hole extending through said cylindrical member slightly above said plunger seat, and threads surrounding an upper portion of said cylindrical member; c. an adjustable nut including inner threads on a lower portion thereof for engaging said threads of said cylindrical member, a configured diaphragm seat extending across a mid-portion of said nut and a plunger means extending downwardly therefrom for engaging in said plunger seat in a nonpressure state; d. a diaphragm being transparent to microwave energy engaged in said adjustable nut in said diaphragm seat whereby pressure during a microwave heating digestion in said vessel causes said plunger to move upwardly against said diaphragm in said diaphragm seat and pass gases and liquids through said downwardly extending hole, about said plunger seat and through said side hole; and, e. means retaining said diaphragm in said adjustable nut.

Claim 14

A microwave heating digestion vessel for use in microwave oven during a microwave heating digestion of a material comprising: a. a molded threaded vessel with threads at an upper end of said vessel for holding at least one material for a microwave heating digestion; b. a mating molded threaded cap for covering said vessel, said vessel and said cap being transparent to microwave energy, said cap including a plunger seat in a cylindrical member affixed to a top of said cap, a downwardly extending hole through said cylindrical member and said cap about said plunger seat and a side hole extending through said cylindrical member slightly above said plunger seat, and threads surrounding an upper portion of said cylindrical member; c. an adjustable nut including inner threads on a lower portion thereof for engaging said threads of said cylindrical member, a configured diaphragm seat extending across a mid-portion of said nut and a plunger means extending downwardly therefrom for engaging in said plunger seat in a nonpressure state; d. a diaphragm being transparent to microwave energy engaged in said adjustable nut in said diaphragm seat whereby pressure during a microwave heating digestion in said vessel causes said plunger to move upwardly against said diaphragm in said diaphragm seat and pass gases and liquids through said downwardly extending hole, about said plunger seat and through said side hole; and, e. means retaining said diaphragm in said adjustable nut.

Claim 15

A microwave heating digestion vessel for use in microwave oven during microwave heating digestion of a material comprising: a. a molded threaded vessel with threads at an upper end of said vessel for holding at least one material for a microwave heating digestion; b. a mating molded cap for covering said vessel, said vessel and said cap being transparent to microwave energy, said cap including a plunger seat in a cylindrical member affixed to a top of said cap, a downwardly extending hole through said cylindrical member and said cap about said plunger seat and a side hole extending through said cylindrical member slightly above said plunger seat, and threads surrounding an upper portion of said cylindrical member; c. an adjustable nut including inner threads on a lower portion thereof for engaging said threads of said cylindrical member, a configured diaphragm seat extending across a mid-portion of said nut and a plunger extending downwardly therefrom for engaging in said plunger seat in a nonpressure state; d. a diaphragm being transparent to microwave energy engaged in said adjustable nut in said diaphragm seat whereby pressure during a microwave heating digestion in said vessel causes said plunger to move upwardly against said diaphragm in said diaphragm seat and pass gases and liquids through said downwardly extending hole, about said plunger seat and through said side hole; and, e. a jacket means surrounding said vessel and said cap.

Claim 16

A microwave heating digestion vessel for use in microwave oven during microwave heating digestion of a material comprising: a. a molded threaded vessel with threads at an upper end of said vessel for holding at least one material for a microwave heating digestion; b. a mating molded cap for covering said vessel, said vessel and said cap being transparent to microwave energy, said cap including a plunger seat in a cylindrical member affixed to a top of said cap, a downwardly extending hole through said cylindrical member and said cap about said plunger seat and a side hole extending through said cylindrical member slightly above said plunger seat, and threads surrounding an upper portion of said cylindrical member; c. an adjustable nut including inner threads on a lower portion thereof for engaging said threads of said cylindrical member, a configured diaphragm seat extending across a mid-portion of said nut and a plunger extending downwardly therefrom for engaging in said plunger seat in a nonpressure state; d. a diaphragm being transparent to microwave energy engaged in said adjustable nut in said diaphragm seat whereby pressure during a microwave heating digestion in said vessel causes said plunger to move upwardly against said diaphragm in said diaphragm seat and pass gases and liquids through said downwardly extending hole, about said plunger seat and through said side hole; and, e. a jacket means surrounding said vessel and said cap.
