Multilayer pull string bag

Abstract

A web of multilayer material folded and sealed to create a gusseted bag comprising a step cut on the upper end of the bag, the bag further comprising a fold, where the fold enables the upper portion of the bag to be sealed to itself with adhesive, the fold running the width of the bag perpendicular to two side edges of the bag, the bag further comprising a pull string, where the pull string runs laterally from one side edge of the bag to the other, flush against the outer layer of the front panel, below the upper terminating edge of the inner layer of the back panel and above the upper terminating edges of the inner layer of the front panel, the outer layer of the front panel, and the outer layer of the back panel.

I claim: 
     
         1 . A bag comprising a web of multilayer material folded and sealed to create a front panel, a back panel, and two gussets,
 wherein the front panel comprises an inner layer and an outer layer, and the back panel comprises an inner layer and an outer layer, each respective layer possessing an upper terminating edge at an upper end of the bag,   the bag further comprising a step cut on the upper end of the bag,   the bag further comprising a fold, where the fold enables the upper end of the bag to be sealed to itself, the fold running the width of the bag perpendicular to two side edges of the bag, whereby the upper terminating edge of the outer layer of the back panel covers the upper terminating edges of the inner layer of the back panel, the inner layer of the front panel, and the outer layer of the front panel,   the bag further comprising adhesive, the adhesive residing in a generally rectangular area on the outer layer of the front panel in an area bound by the fold, the two opposing side edges of the front panel, and the upper terminating edge of the outer layer of the back panel,   the bag further comprising a pull string, where the pull string runs laterally from one side edge of the bag to the other side edge, extending beyond at least one side edge of the bag, the pull string residing flush against the outer layer of the front panel, below the upper terminating edge of the inner layer of the back panel and above the upper terminating edges of the inner layer of the front panel, the outer layer of the front panel, and the outer layer of the back panel.   
     
     
         2 . The bag of  claim 1 , where multilayer material is a pair of colaminated kraft paper layers. 
     
     
         3 . The bag of  claim 1 , where the outer layers of the front panel and the back panel are the same and selected from a group consisting of clay coated paper and kraft paper, where the inner layers of the front panel and the back panel are haft paper. 
     
     
         4 . The bag of  claim 1  further comprising a linear series of perforations on the outer layer of the back panel, the perforations located on front of the bag and generally in parallel alignment with the pull string, and running parallel to the pull string one side of the bag in a length about equal to the length of the folded gusset from the side of the bag towards the inner cavity of the bag. 
     
     
         5 . The bag of  claim 4  where the linear series of perforations are located on both sides of the bag. 
     
     
         6 . The bag of  claim 1 , wherein the pull string abuts and is substantially parallel to the upper terminating edge of the inner layer of the back panel.
