  • Patent number: 6976332
    Abstract: A combination picture retaining and item storing device that has an integrally formed plastic structure. The structure includes at least two sidewalls that extend from a base. At least one of the sidewalls has a hole formed through the sidewall. A storage area is disposed adjacent and integrally formed with the at least two sidewalls. A separate picture retaining member having a translucent planar body including first and second parallel portions are joined at a radius. The first and second parallel portions allow for retention of a picture in a gap formed by the opposing portions. Retaining features formed on an inner surface and around a periphery of the hole positions the picture retaining member within the periphery of the hole and allows for easy removal of the picture retaining member.

  • Publication number: 20040084808
    Abstract: A mold flow pin that is a cylindrical element and includes first and second ends. The first end is attached to an ejector plate of an injection mold. The second end of the cylindrical element is disposed near a gate opening of a mold cavity. The second end includes flow modifying geometry formed on the cylindrical element. The flow geometry is designed to increase a mass of plastic material near the gate opening. The geometry also reduces the injection pressure of the plastic material and increases a flow rate of plastic material into the mold cavity when compared with conventional injection molding gate orifices.
