  • Carton look plastic bag with ear handles
    Patent number: 4989993
    Abstract: A bottom filled, top gusset plastic bag (10, 106) includes a pair of flexible ear handles (24, 26 or 130, 132). The handles include circular hand-receiving openings (76 or 134) and have circular outlines and circular transition regions (78, 80 or 136, 138) are provided between the ear handles (24, 26 or 130, 132) and attached base portions of the handles. The circular hand-receiving openings (76 or 134) and the curved transition regions (78, 80 or 136, 138) function to distribute weight forces substantially across the full width of each side of a filled bag (10, 106).

  • Method of manufacturing a top gusset bag with integral handle
    Patent number: 4913693
    Abstract: A false gusset (12, 82) is positioned between bag panels (26, 28 and 98, 100) to form a bag having a handle (24, 80) at its upper end formed by upward continuations of the sides (26, 28 or 98, 100) of the bag (10, 78). This construction removes the false gusset (12, 82) and the seals (66, 68 or 114, 116) which connects the false gusset (12, 82) to the bag panels (26, 28 or 98, 100) from the forces created by the weight of the bag (10, 78).
