Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
175 words
A one-piece bag tie of resilient thermoplastic material, said tie comprising a generally circular midportion terminating in a pair of generally radially outwardly extending leg portions which are initially spaced apart so the tie can be thrust onto the closed end of a bag or the like to encircle it by said midportion, said generally circular midportion having a crosssectional shape which defines at least one inner corner, said leg portions being retained on the bag by crossing them on each other, one of said leg portions having a segment which is offset from the plane of the rest of the tie, and the second of said leg portions having a U-shaped segment which is bowed toward said one leg portion whereby in crossing said leg portions the offset segment of said one leg portion is thrust through the U-shaped segment of the other leg portion and releasably locked in the crossed condition, and said inner corner serving to prevent slipping of the locked bag tie especially when used on polyethylene bags or the like.
Claim 2
Dependent Claim
175 words
A one-piece bag tie of resilient thermoplastic material, said tie comprising a generally circular midportion terminating in a pair of generally radially outwardly extending leg portions which are initially spaced apart so the tie can be thrust onto the closed end of a bag or the like to encircle it by said midportion, said generally circular midportion having a crosssectional shape which defines at least one inner corner, said leg portions being retained on the bag by crossing them on each other, one of said leg portions having a segment which is offset from the plane of the rest of the tie, and the second of said leg portions having a U-shaped segment which is bowed toward said one leg portion whereby in crossing said leg portions the offset segment of said one leg portion is thrust through the U-shaped segment of the other leg portion and releasably locked in the crossed condition, and said inner corner serving to prevent slipping of the locked bag tie especially when used on polyethylene bags or the like.
Claim 3
Dependent Claim
39 words
A one-piece thermoplastic bag tie as set forth in claim 1 wherein said midportion has a semicircular cross-sectional shape, and said leg portions having cross-sectional shapes with cooperating flat surfaces which abut one another when the tie is locked.
Claim 4
Dependent Claim
48 words
A one-piece thermoplastic bag tie as set forth in claim 2 wherein said second leg portion has the same semicircular cross-sectional shape as said midportion, and wherein said one leg portion has its offset portion defining a flat for cooperating with the flat on said second leg portion.
Claim 5
Dependent Claim
34 words
A one-piece thermoplastic bag tie as set forth in claim 3 wherein said one leg portion has a semicircular cross-sectional shape which is identical to but inverted with respect to said second leg portion.
Claim 6
Dependent Claim
39 words
A one-piece thermoplastic bag tie as set forth in claim 4 wherein said offset portion of said one leg portion has its flat arranged in the same plane as that of the flat surface defined by said circular midportion.
Claim 7
Dependent Claim
38 words
A one-piece thermoplastic bag tie as set forth in claim 5 wherein said U-shaped segment of said second leg portion defines an opening with a depth somewhat greater than the maximum cross-sectional dimension of said offset leg portion.
