Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
89 words
A bag made of flexible sheet plastic material having opposed walls and hems at the mouth ends of said walls with a length of drawcord extending through each hem, edges of the hems where the lengths of drawcord extend out of the hems being of undercut form thereby having laterally projecting upper portions adapted to curve up with portions of said lengths of drawcord which extend upwardly from the hems as used for carrying the bag, thereby minimizing the tendency of the lengths of drawcord to split the hems.
Claim 2
Dependent Claim
89 words
A bag made of flexible sheet plastic material having opposed walls and hems at the mouth ends of said walls with a length of drawcord extending through each hem, edges of the hems where the lengths of drawcord extend out of the hems being of undercut form thereby having laterally projecting upper portions adapted to curve up with portions of said lengths of drawcord which extend upwardly from the hems as used for carrying the bag, thereby minimizing the tendency of the lengths of drawcord to split the hems.
Claim 3
Dependent Claim
130 words
A bag as set forth in claim 1 in which each of said hems has a generally central cutout providing a finger hole for grasping the central portions of said lengths of drawcord for use thereof as a handle, said lengths of drawcord being adapted to be pulled out into loops from opposite sides of said cutouts, when so used as a handle, the side edges of each cutout being of undercut form thereby having upper portions extending laterally inwardly toward one another at opposite sides of the cutout, said upper portions being adapted to curve up with said lengths of drawcord when the latter are pulled out into loops from the opposite sides of the cutouts, thereby minimizing the tendency of the lengths of drawcord to split the hems.
Claim 4
Dependent Claim
31 words
A bag as set forth in claim 2 wherein the side edges of the undercuts are inclined in opposite directions downwardly and laterally outwardly from the mouth end of the bag.
