Table-top electric heat sealer

Abstract

An electric heat sealer including a casing having a first pair of extensions extending outwardly therefrom, a press bar pivotally connected to said casing, the press bar having a second pair of extensions extending outwardly therefrom, at least one sealing mechanism mounted in the press bar or the casing and a source of current for energizing the heating wire. The press bar is normally biased above the casing and the at least one sealing mechanism includes a heating wire.

1 - 38 . (canceled)  
     
     
         39 . An electric heat sealer comprising: 
 (a) a casing,    (b) a press bar pivotally connected to said casing,    (c) at least one sealing mechanism mounted within one of said casing and said press bar, said sealing mechanism having an operating surface and a heating wire disposed on said operating surface,    (d) a source of current, and    (e) a power cord jack mounted to said casing.    
     
     
         40 . The electric heat sealer of  claim 39 , wherein a portion of said heating wire that is disposed on said operating surface includes at least two sections that are non-parallel to one another.  
     
     
         41 . The electric heat sealer of  claim 39  wherein said casing defines a longitudinal axis, and at least one of said at least two sections of said heating wire is oriented non-perpendicularly to said longitudinal axis.  
     
     
         42 . The electric heat sealer of  claim 39  wherein said casing defines a longitudinal axis, and at least one of said at least two sections of said heating wire is oriented substantially parallel to said longitudinal axis.  
     
     
         43 . The electric heat sealer of  claim 39  wherein said at least two sections of said heating wire are substantially perpendicular to one another.  
     
     
         44 . An electric heat sealer comprising: 
 (a) a casing, wherein said casing includes a first pair of extensions extending outwardly therefrom, wherein said first pair of extensions extend in opposite directions,    (b) a press bar pivotally connected to said casing, wherein said press bar includes a second pair of extensions extending outwardly therefrom, wherein said second extensions extend in opposite directions, and wherein said press bar is normally biased above said casing,    (c) a sealing mechanism mounted in said press bar, wherein said sealing mechanism includes 
 (i) a heat insulative base,  
 (ii) a heating wire secured on said heat insulative base, and  
 (iii) a heat resistant cover sheet secured over said heating wire,  
   (d) a source of current for energizing said heating wire, wherein said sealing mechanism extends into said extensions, and    (e) a power cord jack mounted to the casing.    
     
     
         45 . The electric heat sealer of  claim 44 , further comprising an actuation button extending downwardly from said press bar, wherein said heating wire is energized when said press bar is pressed downwardly and said actuation button is urged to electrically connect said source of current to said heating wire.  
     
     
         46 . An electric heat sealer comprising 
 (a) a casing,    (b) a press bar pivotally connected to said casing,    (c) at least one sealing mechanism mounted within one of said casing and said press bar, said sealing mechanism including a heating wire,    (d) a source of current, and    (e) a power cord jack mounted to the casing.    
     
     
         47 . The sealer of  claim 46  wherein said sealing mechanism has an operating surface, wherein a portion of said heating wire disposed on said operating surface includes at least two sections that are non-parallel to one another.  
     
     
         48 . An electric heat sealer comprising 
 (a) a casing,    (b) a press bar pivotally connected to said casing,    (c) at least one sealing mechanism mounted within one of said casing and said press bar, and    (d) a source of current, and    (e) a power cord jack mounted to the casing.    
     
     
         49 . The sealer of  claim 48 , wherein said heating wire has a planar top surface.  
     
     
         50 . The sealer of  claim 48 , wherein said heating wire has a rectangular cross-section.
