A substantially toroidal container for coiled vegetation trimmer line has a front shell and a rear shell capable of bonding at the center with heat and pressure, radio frequency, ultrasonic welding, adhesive, or attachment mechanisms. The bonding of the shells leaves a separation between the outer edges of the shells. The separation is nonlinear around the circumference of the container, so that a user can access the trimmer line, but the trimmer line cannot uncoil and spill out of the container. The separation is preferably defined by a series of offset uniform teeth on the outer edges of the shells. One or more teeth may be removed, providing a line aperture through which the end of the trimmer line extends out of the container. Male and female indices on each shell are used to align the teeth during packaging.
