Abstract
A multi-ply plastic bag from a continuous strip of bags on a roll is supplied to a user with the top of the bag partially opened. A tear line between the bottom of a leading bag and a top of a subsequent bag separates the individual bags. A broad slit centrally located in the tear line passes through all but one ply of the strip of bags. The bag dispenser has an upwardly projecting tongue which engages the slit in the tear line when a user draws a bag from the dispenser. The tongue impedes the subsequent bag from moving forward. The adjacent bags separate along the tear line. The ply which does not have a slit rides over the tongue and pulls apart the plies at the opening of the subsequent bag before the leading bag completely separates from the subsequent bag.
Claims7
A continuous roll of separable plastic bags for use in a dispenser which includes a separating tongue in a predetermined position, each of said bags comprising:
- a multiplicity of plies of flexible plastic film;
- a tear line in each of said plies, each of said tear lines overlying each other and including a perforated portion;
- at least a first of said plies including an elongated slit which is adapted to be engaged by said tongue;
- and
- at least a second of said plies having no perforations in said second ply tear line in the region overlying said elongated slit, whereby said non-perforated portion of said second ply tear line has a greater resistance to tearing than said perforated portion of said second ply tear line such that when a bag is separated from said continuous roll, said bag tends to open.
A continuous roll of separable plastic bags for use in a dispenser which includes a separating tongue in a predetermined position, each of said bags comprising:
- eight plies of flexible plastic film in a star sealed configuration;
- a tear line in each of said plies, each of said tear lines overlying each other and including a perforated portion;
- each of seven of said plies including an elongated slit, wherein each of said elongated slits overlies each other and is adapted to be engaged by said tongue;
- and
- one of said plies having no perforations in said tear line in the region overlying said elongated slits, whereby said non-perforated portion of said one ply tear line has a greater resistance to tearing than said perforated portion of said one ply tear line such that when a bag is separated from said continuous roll, said bag tends to open.
