The invention claimed is: 1. A method of activating an electric heat sealer, said method comprising the steps of: a) providing a hand-held electric heat sealer comprising a housing having a switch mounted thereto and a press bar pivotally connected thereto, the press bar having a press plate, b) pivoting a free end of said press bar, c) biasing said press plate from an at rest position to an activation position, wherein said press plate causes a circuit to be completed, wherein in the at rest position, the press plate biases the press bar above the housing, and d) heating an electric heating wire. 2. The method of claim 1 wherein a portion of said switch protrudes an through opening in said housing, said portion of said switch that protrudes through said opening in said housing coming into contact with said press plate--when said press bar is in said at rest position. 3. The method of claim 2 wherein said portion of said switch that protrudes through said opening in said housing is biased upwardly by a spring. 4. The method of claim 2 wherein said opening includes a pair of opposed notches. 5. The method of claim 1 wherein said hand-held electric heat sealer further comprises a heating unit mounted in said housing, said heating unit including a heat insulative base having a protrusive portion, said electric heating wire being mounted on said protrusive portion. 6. The method of claim 5 wherein said hand-held electric heat sealer further comprises a frame having defined therein an opening having an edge, said opening aligned with at least a portion of said heat insulative base. 7. The method of claim 6 wherein said opening includes a pair of opposed notches. 8. The method of claim 5 wherein said press bar includes a heat insulative press block mounted on said free end, said heat insulative press block being forced against said protrusive middle portion of said heat insulative base when said press bar is biased. 9. The method of claim 1 wherein said press plate is comprised of metal. 10. The method of claim 1 wherein said press plate is connected to said press bar at a point remote from said free end. 11. The method of claim 1 wherein said hand-held electric heat sealer further comprises a heat resistant cover sheet covering at least a portion of said electric heating wire. 12. The method of claim 11 wherein the heat resistant cover sheet is a meshed member made from a heat resistant material. 13. The method of claim 1 wherein said hand-held electric heat sealer is adapted to be supplied with electrical current from a DC current source and an AC current source. 14. The method of claim 1 wherein said housing has a bottom side wall fixedly mounted with a magnetic plate. 15. The method of claim 1 wherein said housing defines a battery chamber, said battery chamber comprising: (a) a front upright support, (b) a rear upright support, (c) first and second front terminal plates respectively mounted on said front upright support, and (d) a pair of rear terminal plates respectively mounted on said rear upright support. 16. The method of claim 1 wherein said hand-held electric heat sealer further comprises a safety device that selectively prevents electrical current from flowing through said electric heating wire, wherein said safety device comprises a protective frame pivotally connected to an outside portion of said housing. 17. The method of claim 16 wherein said protective frame is pivotable between a first position, in which said protective frame is disposed above said heating unit, and a second position, in which said protective frame is not disposed above said heating unit. 18. A method of sealing a plastic bag, said method comprising the steps of: a) providing a hand-held electric heat sealer comprising a housing having a switch mounted thereto and a press bar pivotally connected thereto, said press bar having a press plate that biases the press bar above the housing when the press bar is in an at rest position, b) placing said plastic bag between said housing and said press bar, c) pivoting a free end of said press bar, d) biasing said press plate, wherein said press plate causes a circuit to be completed, e) heating an electric heating wire, and f) sealing said plastic bag. 19. The method of claim 18 wherein a portion of said switch protrudes through an opening in said housing, said portion of said switch that protrudes through said opening in said housing coming into contact with said press plate when said press bar is in said at rest position.
Chou Shu-Hui (No. 104 ; Sec. 2 ; Hsi-Wan Rd. Hsi-Chi Chen ; Taipei Hsien TWX), Electric heat sealer energizable by internal battery set or external AC adapter.
