Stackable tippet spool
A tippet spool is self-orientating when displayed on pegs at retail. The tippet spool also has structures adapted to interlock adjacent tippet spools in a stack with one spool rotatable with respect to its neighbors. The tippet spool is self orientating because of an asymmetrical central opening with the center of mass of the tippet spool opposite the portion of the central opening furthest from the center of the spool.
1. A fishing tippet spool comprising:
a circular trough adapted to contain a length of tippet, said trough being generally symmetrical about a first spool axis, said trough surrounding a central volume adjacent said first spool axis;
an opening within said central volume, said opening surrounded by an opening wall, said opening wall being asymmetrical about said first axis, said opening wall including at least one first portion at a first distance from said first spool axis and at least one second portion at a second distance from said first spool axis, said first distance being greater than said second distance, said first portion being a top outwardly extending portion extending from said first spool axis in a direction defined as a spool top;
a label having a top and information presented on said label, said information more easily read when said label top is orientated in an upward direction;
said tippet spool having a surface supporting said label with said label top orientated with said spool top;
said tippet spool having a center of mass; and,
said center of mass being more distant from said spool top than said first spool axis.
2. The fishing tippet spool of claim 1 wherein said opening wall second portion is a portion of a circle centered on said first spool axis, said portion of a circle leaving two ends.
3. The fishing tippet spool of claim 2 wherein said opening wall first portion extends outwardly between said two ends of said portion of a circle.
4. The fishing tippet spool of claim 3 wherein said opening wall first portion is an arc bowing outwardly between said two ends of said portion of a circle.
5. The fishing tippet spool of claim 4 wherein said arc is a semicircle.
6. The fishing tippet spool of claim 5 wherein said semicircle has a diameter slightly greater than the diameter of the display peg upon which it is to be displayed.
7. The fishing tippet spool of claim 3 wherein said spool has more mass on the side of said first spool axis opposite said spool top than on the side of said first spool axis adjacent said spool top.
8. The fishing tippet spool of claim 7 wherein said spool has a plurality of ribs adjacent said trough, said ribs being on the side of said first spool axis opposite said spool top.
9. The fishing tippet spool of claim 1 wherein said surface supporting said label is a flat disk.
10. The fishing tippet spool of claim 9 wherein said flat disk has a front face supporting said label and a periphery, at least a portion of said disk being adjacent said trough;
a circumferential ridge extending from the front face of said disk at the disk periphery, said circumferential ridge having an edge remote from said disk;
a plurality of shallow tabs extending axially inwardly from the edge of said circumferential ridge remote from said disk;
said trough having a trough bottom and a flange adjacent said trough on the side of said trough opposite said disk, said flange having an outer edge, said flange outer edge adapted to be received within a circumferential ridge of a similar tippet spool and retained by said tabs, whereby similar tippet spools may be releasably held together.
11. The fishing tippet spool of claim 10 wherein said flange edge is circular.
12. A fishing tippet spool comprising
a spool axis;
an annular trough adapted to contain a length of tippet, said trough being generally symmetrical about said spool axis;
a spool front side disk having a central aperture, a periphery, a front face and a rear face, at least a portion of said front side disk being adjacent said trough with said rear face facing said trough;
a circumferential ridge extending from the front face of said disk at the disk periphery, said circumferential ridge having an edge remote from said front side disk;
a plurality of shallow tabs extending radially inwardly from the edge of said circumferential ridge remote from said front side disk,
a trough bottom,
a flange adjacent said trough on the side of said trough opposite said front side disk, said flange having an outer edge, said flange outer edge adapted to be received within a circumferential ridge of a similar tippet spool and retained by said tabs, whereby similar tippet spools are adapted to be releasably and rotatably held together.
13. The fishing tippet spool of claim 12 wherein said plurality of shallow tabs comprise at least three tabs.
14. The fishing tippet spool of claim 13 wherein said tabs are regularly spaced around the circumferential ridge.
15. A fishing tippet spool comprising
a spool axis;
an annular trough adapter to contain a length of tipper, said trough being generally symmetrical about said spool axis;
a spool front side disk having a central aperture, a periphery, a front face and a rear face, at least a portion of said front side disk being adjacent said trough with said rear face facing said trough;
a circumferential ridge extending from the front face of said disk at the disk periphery, said circumferential ridge having an edge remote from said front side disk;
a plurality of shallow tabs extending radially inwardly from the edge of said circumferential ridge remote from said front side disk,
a trough bottom,
a flange adjacent said trough on the side of said trough opposite said front side disk, said flange having an outer edge, said flange outer edge adapted to be received within a circumferential ridge of a similar tippet spool and retained by said tabs, whereby similar tippet spools are adapted to be releasably and rotatably held together,
said front side disk further comprising a center, a top and information presented on the front face of said disk, said information most easily read when said spool is orientated with said disk top uppermost; said tippet spool having a center of mass on the side of said disk center opposite said disk top.
16. The fishing tippet spool of claim 15 wherein said disk central aperture has an edge, said edge being generally equidistant from said disk center except in the direction of sad disk top where said aperture edge is more distant from said disk center than for the remaining portions of said aperture edge.
17. The fishing tippet spool of claim 16 wherein said aperture edge is generally circular and centered at said disk center except for a portion in the direction of said disk top where said aperture edge is further from said disk center.
