## Abstract

A dispenser for a roll of bags joined in series end-to end along transverse severable lines comprising a receptacle in which a roll of bags may be held and rotated to pass the bags through the outlet of the receptacle and a web guide secured to the outlet. The web guide may be provided with a floor and inwardly overhanging side edges with the floor terminating in an upwardly projecting serrated edge which effects separation of each bag from its next ensuing bag.

## Claims

### Claim 1

In combination,
a roll of plastic bags joined in series end-to-end along transverse perforated lines between adjacent bags, each bag having a leading edge, and a trailing edge attached to the leading edge of the next ensuing bag of the roll; and
a dispenser for said roll, said dispenser comprising:
a receptacle configured to receive and hold the bag roll, said receptacle having an outlet, said receptacle permitting the bag roll to be unwound with each bag in the roll as the bag is unwound from the roll passing through the receptacle outlet;
a web guide, said guide extending from the outlet of the receptacle and defining a path extending from the outlet in a first predetermined direction, said web guide comprising a floor, said floor commencing at the receptacle outlet and extending in said first predetermined direction to a terminal edge projecting transversely across the path defined by the web guide, said floor having rising side edges, said terminal edge of said floor being serrated with a plurality of smooth peaks to form a smooth serrated terminal edge to engage each perforated line between adjacent bags, and the terminal edge of the floor being curved convexedly in said first predetermined direction thereby to initiate severance of the bag being pulled from the ensuing bag along the transverse perforated line between said bag being pulled and the next ensuing bag, at the outer ends of said line, and continuing to the center of the line;
whereby, as each bag of the bag roll is unwound from the roll and pulled through the receptacle outlet, it is drawn through the web guide and confined to the floor by the side edges of the guide floor until its trailing edge of the bag reaches the smooth serrated terminal edge of the floor, whereupon, when the bag being pulled is separated from the next ensuing bag along the perforated line between the trailing edge of the bag being pulled and the leading edge of the next ensuing bag by the engagement of the said perforated line with the smooth serrated terminal edge of the floor, the thus detached bag being pulled may be withdrawn for filling or other use, and the next ensuing bag is laid on the web guide floor readied for dispensing.

### Claim 2 (depends on 1)

The combination as described in claim 1 wherein the receptacle outlet and web guide are unitary.
