GUSSET FOR A LIGHT-WEIGHT BAG, A BAG ASSEMBLED THEREFROM, AND METHODS FOR THE MANUFACTURE AND ASSEMBLY THEREOF

摘要

A light-weight side gusset for a bag includes a formed composite frame having a peripheral raised region (46) and a depressed central region (48). An opening through the depressed central region forms a relatively narrow border portion around the inner periphery of the raised region. A central panel (38) corresponding in configuration to the outline of the depressed region is attached to the border portion of the depressed region to cover the opening therethrough. The composite frame is made up of a moldable substrate (40), an outer layer wear-resistant material (42), and an inner adherent layer (44). A complete bag is assembled by securing two such gussets to the body of the bag. Methods of manufacturing the composite frame, a gusset including such frame, and a bag including such gussets are also disclosed.
