A combination as set forth in claim 2 in which said securing means comprises: a collar embracing the two overlapping ends transversely thereof; and A clamping member extending into the collar and being adjustable to exert pressure outwardly against a first portion of the inner surface of the collar and pressure inwardly against the two overlapping strap ends to clamp the two strap ends against a second portion of the inner surface of the collar that is opposite from the first portion.
Claim 7
Dependent Claim 307 words
In a device for positioning inside the open end of a paper bag to expand the open end and enable the bag to stand upright to serve as a self-supporting receptacle, the combination of: a flexible strap forming a closed loop with its opposite ends overlapping; and securing means releasably clamping the overlapping ends of the strap together to permit infinite adjustment in the dimension of the loop to fit into bags of various girth dimensions, said securing means further including a clamping member extending into the collar and adjustable to exert pressure outwardly against a first portion of the inner surface of the collar and pressure inwardly against the two overlapping strap ends to clamp the two strap ends against a second portion of the inner surface of the collar that is opposite from the first portion, said clamping member having a clamping portion extending into the collar from one end thereof and a handle portion extending outwardly from the collar laterally thereof, said clamping portion having a first cross-sectional dimension and a second cross-sectional dimension substantially greater than the first cross-sectional dimension at an angle relative to the first cross-sectional dimension, said handle portion being swingable about the clamping portion as a pivot between a release position extending laterally from the overlapping strap ends at which the first cross-sectional dimension of the clamping portion is interposed between a portion of the inner surface of the collar and the two overlapping strap ends, first cross-sectional dimension of the clamping portion being interposed between the two straps and said first portion of the inner surface of the collar at the release position of the handle portion, said second cross-sectional dimension being of a magnitude to place the collar under substantial stress for clamping action against the overlapping strap ends at the clamping position of the handle portion.
Claim 8
Dependent Claim 307 words
In a device for positioning inside the open end of a paper bag to expand the open end and enable the bag to stand upright to serve as a self-supporting receptacle, the combination of: a flexible strap forming a closed loop with its opposite ends overlapping; and securing means releasably clamping the overlapping ends of the strap together to permit infinite adjustment in the dimension of the loop to fit into bags of various girth dimensions, said securing means further including a clamping member extending into the collar and adjustable to exert pressure outwardly against a first portion of the inner surface of the collar and pressure inwardly against the two overlapping strap ends to clamp the two strap ends against a second portion of the inner surface of the collar that is opposite from the first portion, said clamping member having a clamping portion extending into the collar from one end thereof and a handle portion extending outwardly from the collar laterally thereof, said clamping portion having a first cross-sectional dimension and a second cross-sectional dimension substantially greater than the first cross-sectional dimension at an angle relative to the first cross-sectional dimension, said handle portion being swingable about the clamping portion as a pivot between a release position extending laterally from the overlapping strap ends at which the first cross-sectional dimension of the clamping portion is interposed between a portion of the inner surface of the collar and the two overlapping strap ends, first cross-sectional dimension of the clamping portion being interposed between the two straps and said first portion of the inner surface of the collar at the release position of the handle portion, said second cross-sectional dimension being of a magnitude to place the collar under substantial stress for clamping action against the overlapping strap ends at the clamping position of the handle portion.
Claim 9
Dependent Claim 44 words

Claim 15
Independent Claim 214 words
A method of enabling a paper bag to stand upright in a self-supporting manner to serve as an open receptacle, characterized by the steps of: providing an elongated resiliently flexible member of a length exceeding the girth dimension of the bag; overlapping the opposite ends of the member to form the member into a closed loop; positioning the loop inside the open end of the bag and adjusting the overlap of the ends of the member to expand the loop snugly against the inner surface of the bag; securing the overlapping ends together to maintain the expanded dimension of the loop; removing the expanded loop from inside the bag while the overlapping ends are secured to each other; releasing the overlapping ends from each other temporarily and reducing the overlap to expand the loop further; again securing the overlapping ends together while the loop is thus further expanded; bowing at least one portion of the expanded loop inwardly to distort the loop to configuration of reduced cross dimension; inserting the distorted loop into the open end of the bag; and restoring the configuration of the loop against the inner surface of the bag to place the loop under circumferential compression stress to cause corresponding circumferential tensile stress in the open end of the bag.
Claim 16
Independent Claim 214 words
A method of enabling a paper bag to stand upright in a self-supporting manner to serve as an open receptacle, characterized by the steps of: providing an elongated resiliently flexible member of a length exceeding the girth dimension of the bag; overlapping the opposite ends of the member to form the member into a closed loop; positioning the loop inside the open end of the bag and adjusting the overlap of the ends of the member to expand the loop snugly against the inner surface of the bag; securing the overlapping ends together to maintain the expanded dimension of the loop; removing the expanded loop from inside the bag while the overlapping ends are secured to each other; releasing the overlapping ends from each other temporarily and reducing the overlap to expand the loop further; again securing the overlapping ends together while the loop is thus further expanded; bowing at least one portion of the expanded loop inwardly to distort the loop to configuration of reduced cross dimension; inserting the distorted loop into the open end of the bag; and restoring the configuration of the loop against the inner surface of the bag to place the loop under circumferential compression stress to cause corresponding circumferential tensile stress in the open end of the bag.
