Abstract
An easy opening plastic bag includes a plastic front panel, a plastic rear panel, and plastic left and right end panels coupled to the front and rear panels. A plastic gusset is formed at the top of the bag and is joined to the front, rear, left, and right panels. A first frangible portion is disposed near a top of the front panel, and a second frangible portion is disposed near a top of the rear panel. The first and second frangible portions lie in a plane which allows a portion of the bag to rotate away from the remainder of the bag about an axis parallel to the plane. A third frangible portion is provided in the bag and extends substantially perpendicular to the plane of the first and second frangible portions.
Claims22
An easy opening plastic bag comprising:
- a front panel;
- a rear panel;
- left and right end panels coupled to the front and rear panels;
- a gusset formed at a top of the bag and coupled to the front and rear panels;
- and
- a first frangible line disposed near a top of the front panel;
- a second frangible line disposed near a top of the rear panel;
- a connecting frangible line connecting said first and second frangible lines, the first, second, and connecting frangible lines lying substantially in a plane and allowing a portion of the bag to rotate away from the remainder of the bag about an axis parallel to said plane;
- and
- a third frangible line extending substantially perpendicular to said plane and intersecting at least one of said first, second, and connecting frangible lines.
An easy opening plastic bag for compressed articles, comprising,
- a front panel;
- a rear panel;
- left and right end panels coupled to the front and rear panels;
- a gusset formed at a top of the bag and coupled to the front and rear panels;
- and
- first and second substantially vertical frangible lines respectively disposed in said front and rear panels but not traversing said front and rear panels, to minimize premature tearing caused by circumferential forces created in the bag by the compressed articles, a connecting frangible line connecting the first and second frangible lines so that the bag may be easily opened.
An easy opening bag for compressed articles comprising,
- a front panel;
- a rear panel;
- left and right end panels coupled to the front and rear panels;
- a gusset formed at a top of the bag and coupled to the front and rear panels;
- and
- a frangible line disposed in said front panel, said gusset, and said rear panel but not traversing said front or rear panel to minimize premature tearing caused by circumferential forces.

- a first line of perforations extending up the front panel, across the front handle skirt, across the gusset, across the rear handle skirt, and down the rear panel;
- and
- a second line of perforations spaced apart from said first line of perforations and extending up the front panel, across the front handle skirt, across the gusset, across the rear handle skirt, and down the rear panel.
