Abstract
A reel design is provided which can be easily manufactured as blanks, efficiently stored, quickly assembled and disassembled, and compatible for use in a clean room. The reel is preferably formed from corrugated plastic and comprises two planar flanges, each formed with a plurality of grooves, and a hub secured therebetween, with a corresponding number of tabs integrally formed with the hub and capable of cooperative engagement with the grooves. The hub may be formed to define any diameter and either a cylindric or polygonal profile. Also, the flanges may be formed with grooves circumferentially disposed about the flanges at different locations to accommodate hubs of varying hub diameters.
Claims15
A reel for storing carrier tape and items disposed thereon, said reel comprising:
- two substantially planar flanges, each formed with opposing inner and outer surfaces with a plurality of grooves extending therebetween, said plurality including at least one first short groove, at least one first long groove, at least one second short groove, and at least one second long groove, each said flange being formed about a center, said first short groove being located a first distance from said center, said first long groove being located a second distance from said center, said second short groove being located a third distance from said center, and said second long groove being located a fourth distance from said center, each said distance being different, wherein each said groove having an inner surface defining a length;
- and
- a hub having opposing ends with portions of each said end being in contact with the inner surface of a single said flange, said hub formed to define at least one flap extending from each said end with a semi-circular tab depending from each said flap, wherein the length of said first long grooves is greater than the width of said flaps and the length of said first short grooves is less than the diameter of said semi-circular tabs, and wherein said flaps extend through said first long grooves and said tabs are in engaging contact with the inner surfaces of said flanges adjacent said first short grooves, whereby said hub can alternatively cooperate with said second short and lone grooves.
A set of blanks for forming a reel, said set comprising:
- two substantially planar flange blanks each formed with a plurality of through grooves, said plurality including at least one first short through groove, at least one first long through groove, at least one second short through groove, and at least one second long through groove, each said flange blank being formed about a center, said first short through groove being located a first distance from said center, said first long through groove being located a second distance from said center, said second short through groove being located a third distance from said center, and said second long through groove being located a fourth distance from said center, each said distance being different, wherein said through grooves having inner surfaces each defining a length;
- and
- a hub blank having an elongated central portion formed with two ends and opposing longitudinal edges with at least one flap extending from each said longitudinal edge, each said flap being formed with a depending tab, wherein said central portion, said flaps and said tabs are hingedly connected through fold lines, said tabs formed to define a dimension greater than the length of at least a portion of said short through grooves, said flaps formed to define a width less than the length of at least a portion of said long through grooves, wherein said hub further having a locking tongue extending from one said end of said central portion with a semi-circular ear depending therefrom, a locking through groove being formed adjacent other said end of said central portion, with said semi-circular ear formed to define a diameter and said locking through groove having an inner surface defining a length less than said diameter.
