Draw tape bag with side seal attached elastic strip

Abstract

The bag includes a draw tape that may be used to cinch closed the opening of the bag. The bag may include at least one stretched elastomeric strip attached to the bag edges or the ends of the draw tape in an extended condition. In one embodiment, the draw tape is elastic and is attached to the bag edges.

         6 . The draw tape bag of  claim 1 , wherein both sidewalls form a hem and a draw tape in an extended length is housed within each hem 
     
     
         7 . A draw tape bag comprising:
 a first sidewall;   a second sidewall, the second sidewall joined to the first sidewall by a closed bottom end, a first edge, and a second edge, thereby defining an open top end having a top surface with a top length;   at least one of the sidewalls forming a hem having a top length and extending along the open top end disposed opposite the bottom end having a bottom length, the hem including a draw tape notch at each end of the hem at the first and second edges;   a pliable thermoplastic draw tape in an extended state housed within the hem and having first and second ends;   a strip of elastic material having a fully relaxed length and a stretched expanded length, the elastic strip in the stretched expanded length condition within the hem and attached to the draw tape by seals at the first and second ends of the draw tape;   wherein the elastic strip is not attached to the bag or attached to the draw tape at any intermediate points between the first and second edges..   
     
     
         8 . The draw tape bag of  claim 7 , wherein the draw tape forms a closed loop that is freely accommodated in the hems and not attached to the hems or the bag side walls. 
     
     
         9 . The draw tape bag of  claim 8 , wherein the bag comprises a draw tape notch at each end of the hem at the first and second edges. 
     
     
         10 . The draw tape bag of  claim 7 , wherein the bag comprises a draw tape notch at each end of the hem at the first and second edges. 
     
     
         11 . The draw tape bag of  claim 7 , wherein the length of the extended draw tape and the stretched expanded length of the elastic strip is equal to the bottom length of the bag. 
     
     
         12 . A draw tape bag comprising:
 a first sidewall;   a second sidewall, the second sidewall joined to the first sidewall by a closed bottom end, a first edge, and a second edge, thereby defining an open top end having a top surface with a top length;   at least one of the sidewalls forming a hem having a top length and extending along the open top end disposed opposite the bottom end having a bottom length, the hem including one or more draw tape notches;   an elastic draw tape in an extended state housed within the hem and attached to the bag in an stretched expanded length condition by side seals to the first and second edges of the bag;   wherein the draw tape is not attached to the bag at any intermediate points between the first and second edges.   
     
     
         13 . The draw tape bag of  claim 12 , wherein the bag comprises a draw tape notch centered along the hem between the first and second edges. 
     
     
         14 . The draw tape bag of  claim 12 , wherein the length of the extended draw tape is equal to the bottom length of the bag. 
     
     
         15 . The draw tape bag of  claim 12 , wherein both sidewalls form a hem and an elastic draw tape in an extended length is housed within each hem. 
     
     
         16 . A draw tape bag comprising:
 a first sidewall;   a second sidewall, the second sidewall joined to the first sidewall by a closed bottom end, a first edge, and a second edge, thereby defining an open top end having a top surface with a top length;   at least one of the sidewalls forming a hem having a top length and extending along the open top end disposed opposite the bottom end having a bottom length, the hem including one or more draw tape notches;   a draw tape in an extended state housed within the hem;   wherein an elastic strip is attached to the bag below the hem.
