    摘要: The present invention is directed to a hub for use in a tape casette for winding a recording tape around the periphery of the cylindrical surface. The hub includes a drive shaft inserting hole at the center portion thereof; a notch for fastening the end of the recording tape in association with a tape securing member on the peripheral cylindrical surface; a first and a second surface opposed to each other, each surface having an inner annular surface and an outer annular surface; and a resin injection gate surrounded by a concave recess located in the outer annular surface of the first surface. In addition, the present invention includes a recess formed on the outer annular surface of the second surface at a position opposite to the resin injection gate, the bottom face of the recess being substantially parallel to the outer annular surface of the second surface.

    摘要: A valve pin (4) for controlling an injection amount of molten resin is inserted into a cavity (13), and then the molten resin is injected by way of a gate (10) along the surface of the valve pin (4) into the cavity (13) to be dropped therein, and tip ends of this dropping molten resin merges at a bottom (13a) of the cavity (13) to form a hollow portion (S) between the valve pin (4) and the dropped molten resin. Then, air is blown into the hollow portion (S) from the tip end of the valve pin (4), inflates the hollow portion (S), brings it into contact with the inner surface of the cavity (13), and cools and solidifies this molten resin, so as to attain a hollow molded product (40).
