The bag includes first and second panel portions, and a top flap portion extending from and integral to the second panel portion along a fold line adjacent to an opening between the first and second panel portions. The inner surfaces of the first and second panel portions have surface characteristics rendering them capable of being firmly heat sealed together along the side edges thereof, while the outer surfaces of at least the second panel portion and of the flap portion along the side edges have surface characteristics rendering them capable of only being weakly heat sealed together. The flap portion is initially folded onto the outer surface of the second panel portion and is held thereinplace along the side edges by means of a weakened seam achieved by virtue of heat sealing of the side edges of the first and second panel portions and the flap portion.Type: GrantFiled: January 11, 1985Date of Patent: December 13, 1988Assignee: Poly-Pak Industries, Inc.Inventor: Matthew Barbaro

Patent number: 4760983Abstract: This invention provides a supporting structure for supporting two different types of flexible containers or bags. The structure is capable of supporting open mouth type bags, and in addition, can support handle type bags. Embodiments are disclosed for supporting of both side type handle bags as well as bags provided with handles in the front and rear. The supporting structure for flexible containers comprises retaining means for retaining the open mouth of a flexible container open under tension; means for restraining lateral movement of a container mounted in the device, the means for restraining lateral movement comprising a pair of spaced apart, opposed restraining members extending below the retaining means; opposed engaging means for releasably engaging and retaining a handle of a handle bag; bag bottom supporting means for supporting a bottom of the flexible container; and means for mounting the supporting apparatus.Type: GrantFiled: October 28, 1986Date of Patent: August 2, 1988Assignee: Extrufix Inc.Inventor: Francis B. McNerney

Patent number: 4759639Abstract: The present invention relates to thermoplastic bags which are characterized by two perforated tabs symetrically attached to the front and back walls at the mouth of the bag. Using a sculptured bag or any of several thermoplastic bag structures currently in use (handled or flush-cut; gussetted or flat), the configuration of the two tabs is such that it enables the user to easily open and load the bag while the mouth remains open and the bag in place. Additionally, the placement of the two tabs permits easy loading of a unitary pack on dispensing holders, including armless stands, resulting in more efficient use of time and space by retail users. The placement and scallop design of the tab perforations create stress transfer tips which distribute stress away from creases and slit-seals at the open mouth, preventing tearing or zippering at the mouth of the bag where stress concentration is most likely and permitting greater use of slit-seals and corresponding reduced costs of manufacture.Type: GrantFiled: November 24, 1986Date of Patent: July 26, 1988Inventor: Robert B.

Patent number: 4734148Abstract: A stack of interlocked detachable bags, preferably formed from a thermoplastic foil strip, and each comprising two walls, a front wall and a back wall, preferably at least one handle-shaped incision positioned on one of said walls adjacent an upper filling opening, wherein the individual bags each have an interlock piece and are attached together with the aid of at least one interlock means engaging their interlock pieces, and by means of a row of perforations forming an edge of the interlock piece the individual bags are detachable from the interlocked stack by tearing off. On one of the walls of each bag adjacent an upper filling opening edge of that bag a reinforcing piece, preferably of plastic foil, with the interlock piece is attached so that the interlock piece protrudes above the filling opening edge. Advantageously the inside of the back wall is provided with the protruding interlock and reinforcing pieces.Type: GrantFiled: July 7, 1986Date of Patent: March 29, 1988Assignee: Elmo M.

Patent number: 4691368Abstract: A flexible package that conforms closely to and fully encloses one or more objects with square or rectangular sides is formed of a flexible, light weight, and preferably heat sealable material such as a thermoplastic. In the preferred embodiments, the packaging is manufactured from tubular or parallel sheets of flexible thermoplastic material laid flat to form two layers, which are than folded into a U-shape with the band at the bottom and the side seams heat sealed to form an open topped, double walled package. The package specifications are determined from the dimensions and quantity of the objects to be packaged. Prior to sealing the sides of the package, the bottom portion of the material is tucked up between the sides to a distance equal to one-half the depth of the finished container so that when the objects are placed in the container, the bottom corners spread to form right angles.Type: GrantFiled: June 20, 1985Date of Patent: September 1, 1987Assignee: Ocor Products CorporationInventor: Claude Roessiger
