Molded plastic bundle tie

Claim 2

A molded plastic bundle tie device comprising: an elongated strip of molded plastic, said strip having a leading end, an intermediate strap portion, and a trailing end, said leading end comprising a generally channel-shaped buckle having a flat web and sidewalls, said sidewalls having inwardly directed free ends which extend over said web, said free ends having flanges on their ends which extend towards said web, said sidewalls having opposed sides which are a first predetermined distance apart, each of said depending flanges having an inner side which is opposed to its associated sidewall and is separated therefrom by a second predetermined distance, said intermediate strap portion having a uniform width throughout its length which is equal to said first predetermined distance, said strap portion having a laterally extending locking flange on each of its side edges, said flange extending in the same direction as said sidewalls and having a thickness which is equal to said second predetermined distance, said leading end being of reduced width, said reduced width being less than the distance between the opposed sides of said depending flanges, and interengaging means on said web and on said intermediate strap portion, said interengaging means permitting movement of said intermediate portion through said buckle in one direction to tighten said tie on a bundle and preventing movement of said tie in the direction opposite to said one direction whereby, said tie can be applied to a bundle by wrapping said tie around said bundle, moving said leading end laterally into said buckle and against said web and pulling said strap portion through said buckle until said tie tightly encircles said bundle.

Claim 3

A bundle tie device as set forth in claim 1, said interengaging means comprising teeth.

Claim 4

A bundle tie device as set forth in claim 2, said web having openings adjacent to each side thereof, said openings being in alignment with said inwardly directed free end portions of said sidewalls.

Claim 5

A plastic bundle tie device which is produced in a straight action mold, said device comprising: an elongated strip of molded plastic having a buckle at one end thereof and having an elongated strap portion extending from said buckle, said buckle being generally channel-shaped and comprising a flat web and sidewalls, said sidewalls having inwardly directed free ends and having flanges on said free ends extending towards said web, each of said flanges having an inner side which is spaced from its respective sidewall, said flanges having outer sides which are spaced apart to form a Gap whereby central surface portions of said web which are in alignment with said gap are exposed on one side of said device, said strap portion having a width equal to the distance between the opposed sides of said sidewalls, said strap portion having a laterally extending locking flange on each of its side edges, said flanges extending in the same direction as said sidewalls and having a thickness equal to the distance between each of said flanges and its associated sidewalls, said web having teeth on said one side, said teeth being on said central surface portions of said web, and said web having a core pin opening on each side of said central surface portions, and locking teeth on said strap portion on the side thereof which is opposite to said one side whereby, said bundle tie device can be applied to a bundle by wrapping said strap portion around said bundle, and pulling said strap portion through said buckle, said tie being capable of being produced in a straight action mold by virtue of the provision of said teeth on said central surface portions of said web and said core pin openings on each side of said central surface portions.

Claim 6

A plastic bundle tie device which is produced in a straight action mold, said device comprising: an elongated strip of molded plastic having a buckle at one end thereof and having an elongated strap portion extending from said buckle, said buckle being generally channel-shaped and comprising a flat web and sidewalls, said sidewalls having inwardly directed free ends and having flanges on said free ends extending towards said web, each of said flanges having an inner side which is spaced from its respective sidewall, said flanges having outer sides which are spaced apart to form a Gap whereby central surface portions of said web which are in alignment with said gap are exposed on one side of said device, said strap portion having a width equal to the distance between the opposed sides of said sidewalls, said strap portion having a laterally extending locking flange on each of its side edges, said flanges extending in the same direction as said sidewalls and having a thickness equal to the distance between each of said flanges and its associated sidewalls, said web having teeth on said one side, said teeth being on said central surface portions of said web, and said web having a core pin opening on each side of said central surface portions, and locking teeth on said strap portion on the side thereof which is opposite to said one side whereby, said bundle tie device can be applied to a bundle by wrapping said strap portion around said bundle, and pulling said strap portion through said buckle, said tie being capable of being produced in a straight action mold by virtue of the provision of said teeth on said central surface portions of said web and said core pin openings on each side of said central surface portions.

Claim 7

A bundle tie device as set forth in claim 4, said device having a leading end extending from said strap portion, said leading end having a width which is less than the width of said gap whereby said leading end can be moved laterally through said gap prior to pulling said strap through said buckle.
