Roll of tapered bags suitable for dispensing bags singly

Abstract

Tapered bags are dispensed singly from a roll. They may be made of plastic, paper, aluminum foil, or aluminum foil laminated with plastic. The bags are connected on the roll alternately top-to-top and bottom-to-bottom. Each bag is tapered towards its bottom such that its top-to-top connection with the next bag is wider than the bottom-to-bottom connection. The taper may be formed by folding the bags so that a dispensed bag may be unfolded to have a bottom as wide as the top. Each bottom-to-bottom connection separates the bags along a row of perforations adjacent to a sealed seam of each bag that defines the bag and insures its integrity. A row of closely spaced perforations along the connecting portion between any two bags allows a single end bag to be separated by pulling and tearing along the row of perforations.

We claim:  
     
         1 . A roll of bags to be dispensed singly, each said bag having a top, a bottom, and tapered sides, each bag attached to a next bag in such manner that the top of a first bag is attached to the top of a second adjacent bag, the bottom of said second bag is attached to the bottom of a third adjacent bag in a continual fashion thus forming said roll of bags, 
 wherein the width of each said bag's top is greater than the width of each said bag's bottom,    wherein a row of perforations is disposed between each two adjacent said bags,    wherein said bottoms of adjacent said bags each have a seam closing each said bag at its bottom, and    wherein one said bag is separated from said roll by pulling and tearing along said row of perforations.    
     
     
         2 . The roll of bags of  claim 1  in which said bags are made of plastic.  
     
     
         3 . The roll of bags of  claim 1  in which said bags are made of paper.  
     
     
         4 . The roll of bags of  claim 1  in which said bags are made of aluminum foil.  
     
     
         5 . The roll of bags of  claim 1  in which said bags are made of aluminum foil laminated with plastic.  
     
     
         6 . The roll of bags of  claim 1  in which said bags are folded to form said tapered sides.
