Patent number: 5660479Abstract: A package header arrangement includes a header with first and second opposing films, a tear bead and a support member. The support member is attached to the first film below the tear bead. The tear bead is disposed between the first and second films. When heat and pressure are applied to the first and second films in proximity to the tear bead, the tear bead scores the first and second films creating a breakable tear bead line. When heat and pressure are applied, the tear bead pushes aside the inner layer of the first and second films, weakening the film along the breakable tear bead line without harming the hermetic seal provided by the films. The breakable tear bead line tears easily because it does not have the tough, flexible inner layer of the films to aid in tear resistance. The breakable tear bead line also provides an even tear along a straight line. The support member provides support while tearing along the breakable tear bead line.Type: GrantFiled: February 16, 1996Date of Patent: August 26, 1997Assignee: Reynolds Consumer Products Inc.Inventors: Timothy J.

Patent number: 5346301Abstract: The closable bag with offset end seal comprises a layer of plastic folded over itself to create an elongate strip of interconnected pockets which are separable from one another along the strip to create individual bags. Interposed between free overlying ends of the plastic strip is a gasket made of a heat sealable material having a low surface tension and coefficient of friction. A side edge of these three layers is heat sealed and scored to provide a tamper indicating strip which must be removed to open the bag. Slightly lateral to this strip is a section of the bag where the gasket is heat sealed along its length to one of the layers of plastic, with a remaining inwardly extending portion of the gasket being free to move away from the layer to which it sealed, creating an inwardly directed flap. On a surface of the unattached layer of plastic facing the gasket are provided two spaced apart longitudinal strips of adhesive which cause engagement between the layer of plastic and the gasket flap.Type: GrantFiled: April 2, 1993Date of Patent: September 13, 1994Assignee: Paul W.
