International Classification:

B65D 3000

US Classification:

383 8

Abstract:

A bag formed of a flaccid material for receiving and containing merchandise, the bag being formed by a sheet of such material folded along a fold line to provide two juxtaposed or overlapping generally rectangular wall panels having the side edges thereof joined together, such fold line being tucked inwardly between such overlapping wall panels to form a gusset, and a separate strip of material folded along a fold line extending along the length thereof and disposed within the gusset to extend across the entire width thereof with the fold line of the separate strip of material lying adjacent to the inwardly tucked fold of the sheet of material, the ends of the strip of material being joined to the overlapping portions of the wall panels by a heat seal extending diagonally at a forty-five degree angle across the corners thereof. The separate strip of material may be cut and formed by accessory equipment, and then inserted in the gusset by the same apparatus used to form the gusset in conventional bag forming equipment.

Abstract:

A bag formed of a flaccid material for receiving and containing merchandise, the bag being formed by a sheet of such material folded along a fold line to provide two juxtaposed or overlapping wall panels having adjacent side edges which are joined to one another. The fold line is tucked inwardly between the wall panels forming top edges along the wall panels and forming a gusset with the overlapping portions of the wall panels. A separate strip of material is folded lengthwise along a fold line and is disposed about the surfaces of the wall panels externally of the gusset with the fold line of the strip extending generally parallel and adjacent to the top edges of the wall panels. The side portions of the strip are joined at each end thereof to the respective adjacent external surface of the wall panel by seals formed in V-shaped patterns defined by lines extending diagonally at substantially a forty-five degree angle between the side edges and the top edges of the wall panels. The strip is formed with a slit at each end which extends a predetermined length along the fold line. The predetermined length of the slit is sufficiently long to permit the side portions of the strip to separate at the ends of the strip and to permit the wall panels to assume an open disposition when the bag is filled, and so that the strip will extend across the end panel in proximity thereto to provide a handle for the bag.
