Abstract
A tape reel is described which is a one-piece, integrally, molded member. A planar continuous flange is connected to a central hub. A plurality of petals or ears is molded in an upright condition to be movably connected to the upper end of the hub. The ears are pushed down to be parallel with the plane of the lower flange to receive tape. The ears are held in place by cooperating members formed on both the ears and hub. Finally, a friction button can be formed separately and assembled on the hub, or may be integrally molded of the hub.
