Plurality of bags and method of making the same

Abstract

A plurality of bags, sleeves, or pouches are detachably joined and provided on a roll. The bags, sleeves, or pouches may be made by joining or by folding the material and forming spaced seal and tear lines in the material. The seal and tear lines are formed in the material by a seal bar having a saw tooth surface which forms alternating sealed and cut portions and uncut portions in the material

What is claimed is:  
     
         1  A plurality of bags, comprising 
 material folded over with a first part of said material overlying a second part of said material,  
 a plurality of sealed and tear lines in said first and second parts of said material, said seal and tear lines spaced a predetermined distance from each other to define individual bags between adjacent seal and tear lines, each said seal and tear line defined by alternating sections of cut and sealed portions and uncut portions of said material.  
 
     
     
         2 . The plurality of bags claimed in  claim 1  wherein said first part of said material extends beyond said second part of said material to define a flap.  
     
     
         3 . The plurality of bags claimed in  claim 3  comprising adhesive on said flap.  
     
     
         4 . The plurality of bags claimed in  claim 1  wherein a cavity for holding an object to be protected by said bags is defined between said first part of said material and said second part of said material  
     
     
         5  The plurality of bags claimed in  claim 1  wherein said bags are rolled onto a roll  
     
     
         6  A method of making a plurality of bags detachably connected together, comprising 
 providing bag material,  
 folding a part of said material onto itself, and  
 forming in said folded material a seal and tear line having sealed and cut portions of said material alternating with uncut portions of said material.  
 
     
     
         7  The method of making a plurality of bags claimed in  claim 6 , said step of forming a seal and tear line in said material is repeated to define individual bags between adjacent seal and tear lines.  
     
     
         8  The method of making a plurality of bags claimed in  claim 6  wherein said step of folding a part of said material further comprises folding said part of said material to define a flap of material  
     
     
         9 . The method of making a plurality of bags claimed in  claim 8  further comprising applying securement means to said flap for securing said flap to said bag in a bag closed configuration.  
     
     
         10 . The method of making a plurality of bags claimed in  claim 6  further comprising providing a saw tooth configured seal bar for forming said seal and tear line in said material.  
     
     
         11 . A seal bar for forming a seal and tear line in material to define bags, sleeves, or pouches and the like, comprising 
 an elongated body, said elongated body having a top surface and a bottom surface, said bottom surface having alternating raised portions and recesses in a saw tooth configuration    
     
     
         12 . The seal bar claimed in  claim 11 , said elongated body having a tapered configuration narrowing from said top surface to said bottom surface  
     
     
         13  A plurality of bags, sleeves, or pouches and the like, comprising 
 a web of material, said material defining first and second side walls,  
 a plurality of spaced tear lines in said web of material defining bags, sleeves, or pouches and the like between adjacent tear lines, said tear lines defined by alternating sections of sealed and cut portions and uncut portions of said web of material  
 
     
     
         14  The plurality of bags, sleeves, or pouches and the like claimed in  claim 13  further comprising a flap on said second side wall extending beyond said first side wall.  
     
     
         15 . The plurality of bags, sleeves, or pouches and the like claimed in  claim 14  further comprising closure means for releasably securing said flap to said first side wall.  
     
     
         16  A method of making a plurality of bags, sleeves, or pouches and the like, comprising 
 providing material,  
 forming a first wall of said material and a second wall of said material, and  
 forming a tear line having sealed and cut portions and uncut portions in said first wall of material and said second wall of material to at least partially seal said first wall of material to said second wall of material  
 
     
     
         17  The method claimed in  claim 16  further comprising forming a flap on said second wall of said material  
     
     
         18 . The method claimed in  claim 17  further comprising providing securement means on said flap for securing said flap to said first wall of said material  
     
     
         19  The method claimed in  claim 16  further comprising forming said tear line using a saw tooth configured seal bar
