Abstract
The present invention comprises a refillable tape dispenser comprising a housing including a side wall, and a tubular hub having a longitudinal axis defining an axial direction, and a first end fixed to the side wall. The hub comprises a continuous base portion joined to the side wall, first and second opposed arcuate guide portions, and first and second opposed arcuate flexible portions which have distal ends remote from the continuous base portion. The first and second flexible portions have axially extending side surfaces defining a non-diametrical chord for the cylindrical hub and have a retaining lug at their distal ends. The retaining lugs have a remote end spaced axially from the distal ends of the flexible portions, a first retaining surface projecting radially outward of the flexible portion, and a second retaining surface projecting radially inward of the flexible portion. The retaining lugs have cam surfaces diverging from the remote end of the retaining lug toward the first and second retaining surfaces. The present invention also includes associated backcards for the dispenser.
