Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
268 words
In a pad of flat bottom bags formed from flexible plastic material of film thickness dimensions, in which the bags thereof are in flattened congruent relation, with each bag including side end seals at either end of same and extending longitudinally of the ends of the respective bags, a bottom fold extending between the bag side ends and gusseted for flat bottom shaping when the bag is open, a front panel extending between the bag side ends and lengthwise of the bottom fold thereof and including a free top edging forming the mouth of the bag, a back panel that extends between the bag side ends and lengthwise of the bottom fold thereof and including a back panel flange projecting a predetermined distance outwardly of the bag mouth to define an edging paralleling the bag bottom fold, with said bags being heat sealed together in said flattened congruent relation along the back panel flange edging, the improvement wherein: the upper corners of each bag at either side of same are defined by diagonal edges of the bag front and back panels that extend from adjacent said back panel flange edging of the respective bags to adjacent the respective side end seals of each bag, with said back panel flanges of the respective bags including a score line paralleling the bag bottom fold and spaced between the bag mouth and the bag back panel flange edging, said diagonal edges of the bags extending below the mid level of the respective bags, and said diagonal edges of the bags and said score lines being in congruent relation in the pad.
Claim 2
Dependent Claim
268 words
In a pad of flat bottom bags formed from flexible plastic material of film thickness dimensions, in which the bags thereof are in flattened congruent relation, with each bag including side end seals at either end of same and extending longitudinally of the ends of the respective bags, a bottom fold extending between the bag side ends and gusseted for flat bottom shaping when the bag is open, a front panel extending between the bag side ends and lengthwise of the bottom fold thereof and including a free top edging forming the mouth of the bag, a back panel that extends between the bag side ends and lengthwise of the bottom fold thereof and including a back panel flange projecting a predetermined distance outwardly of the bag mouth to define an edging paralleling the bag bottom fold, with said bags being heat sealed together in said flattened congruent relation along the back panel flange edging, the improvement wherein: the upper corners of each bag at either side of same are defined by diagonal edges of the bag front and back panels that extend from adjacent said back panel flange edging of the respective bags to adjacent the respective side end seals of each bag, with said back panel flanges of the respective bags including a score line paralleling the bag bottom fold and spaced between the bag mouth and the bag back panel flange edging, said diagonal edges of the bags extending below the mid level of the respective bags, and said diagonal edges of the bags and said score lines being in congruent relation in the pad.
Claim 3
Dependent Claim
34 words
The improvement set forth in claim 1 wherein: at least one aperture extends through said pad between said congruently oriented score lines and the bag pad bonding at the bag back panel flange edgings.
Claim 4
Dependent Claim
60 words
The improvement set forth in claim 2 wherein: said aperture is centered along the bag pad back panel flanges, and including a pair of supplemental apertures extending through said pad back panel flanges at substantially equal distances to either side of the first mentioned aperture, said pair of apertures being equally spaced from the bag pad back panel flange edgings.
Claim 5
Dependent Claim
41 words
The improvement set forth in claim 1 wherein: said bag diagonal edges are rectilinear for their full lengths and intersect the respective bag side end seals at approximately one third of the height of the respective bags in their flattened relation.
Claim 6
Dependent Claim
45 words
The improvement set forth in claim 1 wherein: said bag diagonal edges are rectilinear and are in tangent relation with curvilinear edgings that intersect the respective bag side end seals at approximately one third of the height of the respective bags in their flattened relation.
Claim 7
Dependent Claim
65 words
The improvement set forth in claim 1 wherein: said bag back panel flanges at said edgings of same project depthwise of the respective bags a predetermined similar dimension for forming a common heat bonding area of the pad bags, and wherein the front and back panels of the respective bags are adhered together by a spot seal along the longitudinal centerline of the respective bags.
Claim 8
Dependent Claim
22 words
The improvement set forth in claim 6 wherein: said spot seals are located adjacent but spaced from the respective bag bottom folds.
