Abstract
Abstract A resealable reusable flexible plastic bag with a loop handle is disclosed for packaging heavy loads, for example large quantities of granular goods such as dog foods, in a sealed manner. The bag comprises flexible outer panels connected by a flexible gusset, inner flexible panels also connected by a flexible gusset, and a closure having flexible mating portions connected to the outer gusset. The outer gusset includes a frangible portion such as a line of perforations to facilitate access to the inner gusset. The inner gusset also includes a frangible portion to facilitate access to the goods therein. The flexible mating portions of the closure are separably connectable to each other to prevent access to the goods when connected and to facilitate access to the goods when separated.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
282 words
A resealable reusable flexible plastic bag comprising an outer unitary piece of flexible plastic material including generally rectangular front and rear plastic panels and a gusset connecting said panels at a first end portion of the bag, an inner unitary piece of flexible plastic material including generally rectangular front and rear panels and a gusset connecting said last-mentioned panels at said first end portion of the bag, the ends of said inner and outer unitary pieces of flexible plastic material opposite said first end of the bag being open to facilitate introducing goods into the bag, the side edges of said gussets and said panels being connected together in a manner so that the bag when filled can approximate the shape of a hexahedron with said gusset of said outer piece of flexible plastic material being flattened and closing said first end portion of the bag, a handle defined by a loop of flexible plastic material having ends and being secured at each of its ends to a separate one of said panels of said outer piece of flexible plastic material adjacent said gusset of said outer piece of flexible plastic material, at least a portion of each of said gussets being frangible so as to facilitate access to the goods in the bag and thereafter permit reuse of the bag, and closure means having first and second mating portions separably connectable to each other and connected to said gusset of said outer piece of flexible plastic material so as to prevent access to the goods in the bag when said mating portions are connected together and for facilitating access to the goods in the bag when said mating portions are separated.
Claim 2
Dependent Claim
