Abstract
Abstract Bobbins for supporting textile fiber yarn are disclosed whose opposed ends are of a configuration which allows the top portion of the bobbin to nest within the interior of the bottom portion of a bobbin of the same configuration thereby rendering the bobbins disclosed readily stackable for packaging and subsequent shipment.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
228 words
A textile bobbin having a hollow interior comprising a generally cylindrical body, having at the bottom thereof a hub of greater perimeter than the circumference of any cross-section of the cylindrical body taken perpendicular to the axis of said cylindrical body, said cylindrical body having at the apex thereof a flange member of greater cross-sectional diameter than the aperture of the interior of the base of said bobbin, said flange member having a surface at the top thereof disposed perpendicular to the axis of said cylindrical body, said hub and said flange defining the length of the yarn package to be wound on said cylindrical body of said bobbin, said bobbin having an extension at the top of said flange of a configuration wherein the maximum cross-sectional diameter of said extension is 10 to 30 one thousandths of an inch less than the cross-sectional diameter of the interior of the bobbin at a point which, when two of said bobbins are nested with the top of one inside the bottom of the other, the periphery of the extension at the maximum cross-sectional diameter is adjacent to said point, and the bottom of said hub of one bobbin rests on the surface of said flange of the other bobbin, said extension at the top of said flange being of sufficient length to impart vertical stability to the nested bobbins.
Claim 2
Dependent Claim
228 words
A textile bobbin having a hollow interior comprising a generally cylindrical body, having at the bottom thereof a hub of greater perimeter than the circumference of any cross-section of the cylindrical body taken perpendicular to the axis of said cylindrical body, said cylindrical body having at the apex thereof a flange member of greater cross-sectional diameter than the aperture of the interior of the base of said bobbin, said flange member having a surface at the top thereof disposed perpendicular to the axis of said cylindrical body, said hub and said flange defining the length of the yarn package to be wound on said cylindrical body of said bobbin, said bobbin having an extension at the top of said flange of a configuration wherein the maximum cross-sectional diameter of said extension is 10 to 30 one thousandths of an inch less than the cross-sectional diameter of the interior of the bobbin at a point which, when two of said bobbins are nested with the top of one inside the bottom of the other, the periphery of the extension at the maximum cross-sectional diameter is adjacent to said point, and the bottom of said hub of one bobbin rests on the surface of said flange of the other bobbin, said extension at the top of said flange being of sufficient length to impart vertical stability to the nested bobbins.
Claim 3
Dependent Claim
19 words
The bobbin of claim 1 wherein the extension is generally cylindrical with a flange positioned at the apex thereof.
Claim 4
Dependent Claim
8 words
The bobbin of claim 1 constructed of polystyrene.
Claim 5
Dependent Claim
17 words
The bobbin of claim 1 wherein the gennerally cylindrical body has recurring ridges on the surface thereof.
Claim 6
Dependent Claim
309 words
Two bobbins nested vertically, the top of one inside the bottom of the other, the first bobbin having at the bottom thereof a hub of greater perimeter than the circumference of any cross-section of the cylindrical body taken perpendicular to the axis of said cylindrical body, said cylindrical body having at the apex thereof a flange member of greater cross-sectional diameter than the aperture of the interior of the base of said bobbin, said flange member having a surface at the top thereof disposed perpendicular to the axis of said cylindrical body, said hub and said flange defining the length of the yarn package to be wound on said cylindrical body of said bobbin, said bobbin having an extension at the top of said flange of a configuration wherein the maximum cross-sectional diameter of said extension is 10 to 30 one thousandths of an inch less than the cross-sectional diameter of the interior of the bobbin at a point which, when two of said bobbins are nested with the top of one inside the bottom of the other, the periphery of the extension at the maximum cross-sectional diameter is adjacent to said point, and the bottom of said hub of one bobbin rest on the surface of said flange of the other bobbin, said extension at the top of said flange being of sufficient length to impart vertical stability to the nested bobbins; the second bobbin having the same configuration as the first bobbin; the extension of the first bobbin positioned in the interior of the bottom of the second bobbin, with the bottom of the second bobbin resting on the flange at the apex of the body of the first bobbin and the extension of the first bobbin being positioned a sufficient distance inside the bottom of the second bobbin to provide vertical stability to the nested bobbins.
Claim 7
Dependent Claim
309 words
Two bobbins nested vertically, the top of one inside the bottom of the other, the first bobbin having at the bottom thereof a hub of greater perimeter than the circumference of any cross-section of the cylindrical body taken perpendicular to the axis of said cylindrical body, said cylindrical body having at the apex thereof a flange member of greater cross-sectional diameter than the aperture of the interior of the base of said bobbin, said flange member having a surface at the top thereof disposed perpendicular to the axis of said cylindrical body, said hub and said flange defining the length of the yarn package to be wound on said cylindrical body of said bobbin, said bobbin having an extension at the top of said flange of a configuration wherein the maximum cross-sectional diameter of said extension is 10 to 30 one thousandths of an inch less than the cross-sectional diameter of the interior of the bobbin at a point which, when two of said bobbins are nested with the top of one inside the bottom of the other, the periphery of the extension at the maximum cross-sectional diameter is adjacent to said point, and the bottom of said hub of one bobbin rest on the surface of said flange of the other bobbin, said extension at the top of said flange being of sufficient length to impart vertical stability to the nested bobbins; the second bobbin having the same configuration as the first bobbin; the extension of the first bobbin positioned in the interior of the bottom of the second bobbin, with the bottom of the second bobbin resting on the flange at the apex of the body of the first bobbin and the extension of the first bobbin being positioned a sufficient distance inside the bottom of the second bobbin to provide vertical stability to the nested bobbins.
