  • Patent number: 6361381
    Abstract: A method for manufacturing a plastic cover for a connector bar that includes providing a mold having a substantially rectangular shaped block, having a first surface and a second surface adjacent the first surface. Both the first and second surfaces each have at least one generally cylindrically shaped projection extending outwardly away from the respective surfaces. To form the plastic cover, the mold is dipped into a polymer solution and is allowed to dwell in the solution for a certain period of time. Next, the plastic cover is cured for a sufficient period of time so that the polymer solution hardens to form the plastic cover. After the cover is formed around the mold, it is removed from within the cover through a slit opening. After the mold is removed from the cover, a connector bar can be inserted through the opening into the cover's cavity.

  • Patent number: 6318627
    Abstract: A one-piece upright hollow vending cabinet is formed by rotomolding a thermoplastics material and includes an upper portion supported by an integrally connected lower portion. The upper portion has internal walls defining a first chamber for receiving a stack of paper publications, and a pivotal front door provides access to the chamber and publications. The lower portion of the cabinet defines a second chamber for receiving a flowable ballast material such as sand or gravel, and includes a flared base portion having a bottom wall with an inverted funnel portion. The funnel portion has a top port for pouring the ballast material into the second chamber when the box is inverted, and a removable plug closes the port.
