Abstract

Abstract A bottom filled, top gusset plastic bag (10, 106) includes a pair of flexible ear handles (24, 26 or 130, 132). The handles include circular hand-receiving openings (76 or 134) and have circular outlines and circular transition regions (78, 80 or 136, 138) are provided between the ear handles (24, 26 or 130, 132) and attached base portions of the handles. The circular hand-receiving openings (76 or 134) and the curved transition regions (78, 80 or 136, 138) function to distribute weight forces substantially across the full width of each side of a filled bag (10, 106).

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 276 words
A plastic bag, comprising: a bag web of thermoplastic material folded laterally on itself to form front and rear panels, a top gusset between the panels at one end of the bag, and a fill opening at a second end of the bag, said panels having parallel side edges, and said top gusset having end edges colinear with and positioned between upper portions of the side edges of the panels when the bag is flat and unfilled; side seals connecting the side edges of the panels together, and further connecting the end edges of the top gusset together and to the upper portions of the side edges of the panels, in a manner resulting in the bag, when filled, assuming a substantially hexahedral shape and the gusset being substantially flat and forming a closed top for the bag; handle web panels of thermoplastic material, one on each side of the bag, said panels having inner edge attachment portions contiguous the front and rear panels of the bag web adjacent the top gusset, and central ear handles extending from the attachment portions, said central ear handles being substantially identical in size and shape and including substantially circular hand-receiving openings; said attachment portions extending the full width of the front and rear panels and including end edges contiguous the side seals; connecting seals connecting the attachment portions to outer regions of the front and rear panels of the bag web adjacent the top gusset, said connecting seals also extending the full width of the front and rear panels; and wherein in use the bag is filled through the fill opening and then the second end is sealed shut.
Claim 2
Dependent Claim 276 words
A plastic bag, comprising: a bag web of thermoplastic material folded laterally on itself to form front and rear panels, a top gusset between the panels at one end of the bag, and a fill opening at a second end of the bag, said panels having parallel side edges, and said top gusset having end edges colinear with and positioned between upper portions of the side edges of the panels when the bag is flat and unfilled; side seals connecting the side edges of the panels together, and further connecting the end edges of the top gusset together and to the upper portions of the side edges of the panels, in a manner resulting in the bag, when filled, assuming a substantially hexahedral shape and the gusset being substantially flat and forming a closed top for the bag; handle web panels of thermoplastic material, one on each side of the bag, said panels having inner edge attachment portions contiguous the front and rear panels of the bag web adjacent the top gusset, and central ear handles extending from the attachment portions, said central ear handles being substantially identical in size and shape and including substantially circular hand-receiving openings; said attachment portions extending the full width of the front and rear panels and including end edges contiguous the side seals; connecting seals connecting the attachment portions to outer regions of the front and rear panels of the bag web adjacent the top gusset, said connecting seals also extending the full width of the front and rear panels; and wherein in use the bag is filled through the fill opening and then the second end is sealed shut.
Claim 3
Dependent Claim 18 words
A plastic bag according to claim 1, wherein the central ear handles each have a generally circular outline.
Claim 4
Dependent Claim 26 words
A plastic bag according to claim 2, wherein the generally circular outline of the central ear handles is substantially concentric with the substantially circular hand-receiving openings.
Claim 5
Dependent Claim 18 words
A plastic bag according to claim 1, comprising a breakable connection initially connecting the central ear handles together.
Claim 6
Dependent Claim 50 words
A plastic bag according to claim 4, wherein the handle web panels are opposite side portions of a handle web that has been folded laterally on itself, and the breakable connection is a narrow connection between the two handle web portions of the outer boundaries of the central ear portions.
Claim 7
Dependent Claim 25 words
A plastic bag according to claim 4, wherein the breakable connection is at least one heat seal connecting together edge portions of the ear handles.
Claim 8
Dependent Claim 18 words
A plastic bag according to claim 2, comprising a breakable connection initially connecting the central ear handles together.
Claim 9
Dependent Claim 50 words
A plastic bag according to claim 7, wherein the handle web panels are opposite side portions of a handle web that has been folded laterally on itself, and the breakable connection is a narrow connection between the two handle web portions of the outer boundaries of the central ear portions.
Claim 10
Dependent Claim 25 words
A plastic bag according to claim 7, wherein the breakable connection is at least one heat seal connecting together edge portions of the ear handles.
Claim 11
Dependent Claim 18 words
A plastic bag according to claim 7, comprising a breakable connection initially connecting the central ear handles together.
Claim 12
Dependent Claim 50 words
A plastic bag according to claim 10, wherein the handle web panels are opposite side portions of a handle web that has been folded laterally on itself, and the breakable connection is a narrow connection between the two handle web portions of the outer boundaries of the central ear portions.
Claim 13
Dependent Claim 25 words
