Method of packaging a coiled trimmer line
DCFirst Claim
1. A method of packaging coiled plastic trimmer line including the steps of:
- placing a pre-formed plastic container having an opening, with an outwardly-extending flange about the opening thereof, on a backing sheet of plastic material having an aperture formed therein, with the flange of said pre-formed plastic container engaging the sheet;
heat-bonding the flange of the pre-formed plastic container to the backing sheet to form a melt seal of the flange with the backing sheet; and
winding plastic trimmer line having a range of diameter from 0.050" to 0.155" through said aperture into said opening of the pre-formed plastic container into a coil, having approximately one twist per coil, after the flange thereof is bonded to the backing sheet.

Abstract
A method and apparatus for packaging coiled nylon copolymer trimmer line comprises making the package of plastic material which is capable of melt bonding, either by the application of heat and pressure, radio frequency (RF) or by ultrasonic welding. The container comprises a backing sheet and a pre-formed bubble having an opening in it, with a flange extending outwardly around the opening. The flange is placed on the backing sheet; and the two sheets are heat-melt bonded together by a suitable technique, to produce a strong, integral package which significantly resists separation of the flange from the backing sheet. After the package has been formed, nylon or nylon copolymer, or other plastic, trimmer line is wound into the package, and the bond between the flange and the backing sheet is greater than the compression spring force exerted by the wound trimmer line against the package, preventing separation of the package parts from one another.
