Abstract
A disposable, cord dispensing cartridge comprised of a rigid, shatterproof plastic housing including first and second housing sections having inner and outer surfaces which are ultrasonically secured to each other. The housing includes an internal cord-holding cavity of cylindrical shape dimensioned to receive a spool having two circular flange portions connected by a stem portion. The spool is dimensioned to retain a predetermined length of high strength, small diameter cord which is machine-wound in dense-packed fashion thereon.
Claims6
A cord dispensing cartridge comprising:
- a rigid, shatter-proof, generally U-shaped plastic housing, said housing including:
- first and second housing sections having inner and outer surfaces, which housing sections are ultrasonically welded to each other and define a cord holding cavity of cylindrical shape and a plurality of separate, smaller, air-tight flotation cavities within said plastic housing;
- a spool having two flat, circular flange portions connected by a small-diameter stem portion totally enclosed within said housing, said spool dimensioned to occupy substantially the entire space defined by said cylindrical cavity;
- a predetermined length of high-strength nylon cord machine wound in dense-packed fashion about said stem portion of said spool;
- and,
- blade means operable to sever said nylon cord, said blade means being stationary and fixedly mounted to said housing by being wedged between said first housing section and said second housing section with a cutting edge oriented inwardly toward said housing and disposed within said outer surface of said housing.

A cord dispensing cartridge comprising:
- a rigid, shatter-proof plastic housing including first and second housing sections having inner and outer surfaces, which are ultrasonically welded to each other and which define a cord-holding cavity of cylindrical shape, one of said housing sections including support means integrally formed therewith extending axially through said cylindrical cavity between said first and second housing sections;
- a spool having two flat, circular flange portions connected by a small-diameter stem portion totally enclosed within said cylindrical cavity of said housing, said spool including a longitudinally extending aperture therethrough dimensioned to receiving said support means therein;
- a predetermined length of high-strength nylon cord packed about said stem portion of said spool;
- and,
- blade means having a cutting edge operable to sever said nylon cord, said blade means being stationary and fixedly mounted to said housing by being wedged between said first housing section and said second housing section and disposed within a recess in said outer surface of said housing with said cutting edge oriented inwardly toward said housing.
