ABSTRACT:
A plastic tape reel comprising a hub consisting of an outer cylindrical part adapted to permit a tape to be wound into a roll thereon and an inner cylindrical part defining a hollow pocket for engagement with the reel engaging shaft and two flanges attached one each to the opposite ends of the hub. The annular portion connecting the inner cylindrical part and the outer cylindrical part of the hub is bent in the axial direction throughout the entire circumferential extent so that the inner boundary thereof joins one axial end of the inner cylindrical part and the outer boundary thereof joins the outer cylindrical part at a location halfway along the entire axial length thereof. In the annular depression on the reverse side of the bent portion, a plurality of ribs are disposed in the radial directions and spaced by suitable circumferential intervals. The ribs serve as auxiliary paths for molten resin at the time the tape reel is injection molded.
