The unitary cover comprises a central circular wall of a size corresponding to the container open end.

Description
- This invention relates to a drum cover and, more particularly, to a cover of reduced wall thickness.
- In one form of conventional shipping and storage container, a drum comprises a tubular container having an open end with a cylindrical connecting bead at the open end. The connecting bead may be provided by a metal connecting ring rolled onto the side wall or a plastic connecting ring molded directly to or otherwise adhered to the side wall. Alternatively, the side wall may be of molded plastic construction with an integral connecting bead.
- The conventional drum includes a removable cover for closing the open end of the tubular side wall. A typical cover includes a central circular wall with a peripheral connecting flange receivable on the connecting bead so that the circular wall closes the open end of the container. A locking band secures the cover on the drum. While such a container may be used for storage purposes, often the containers must be lifted by lifting equipment. Advantageously, the drum should be designed to accommodate parrot beak drum lifting devices. If the cover is not of sufficient thickness, the drum may not pass a typical parrot beak test. Typically, such a cover includes circular channels or rings formed in the circular wall providing a corrugated or wave-like appearance.
- A typical cover is formed of molded synthetic resin, such as high density polyethylene. In designing such a cover, consideration may be given to minimizing weight and cost of the cover while also satisfying test requirements. As such, a conventional cover is manufactured having a wall thickness sufficient to pass a parrot beak test. A typical cover for a 21½″ drum has a wall thickness on the order of 0.09″ nominal. Lesser thickness covers have been considered, but have not always successfully passed this test.
- The present invention is directed to solving one or more of the problems discussed above in a novel and simple manner.
- In accordance with the invention, there is provided a cover for use with a tubular container including areas of different wall thickness.
- Broadly, in accordance with one aspect of the invention, there is disclosed a unitary cover used with a tubular container having an open end with a cylindrical connecting bead at the open end. The unitary cover comprises a central circular wall of a size corresponding to the container open end. A concentric ring region surrounds the central circular wall and defines a peripheral flange having a downwardly opening channel receivable on the cylindrical connecting bead to close the open end of the container. The peripheral flange has a substantially greater wall thickness than the central circular wall.
- It is a feature of the invention that the cover comprises a wall thickness nominally about 0.09 inches for the peripheral flange and a wall thickness nominally 0.06 inches for the central circular wall.
- It is another feature of the invention that the concentric ring region comprises first and second concentric rings disposed between the peripheral flange and the central circular wall to define a generally corrugated structure.
- It is still another feature of the invention that wall thickness of the concentric ring region gradually decreases transitioning from the peripheral flange to the central circular wall.
- It is still another feature of the invention that the peripheral flange has a wall thickness about 50% greater then wall thickness of the central circular wall.
- There is disclosed in accordance with another aspect of the invention a unitary cover for use with a tubular container having an open end with a cylindrical connecting bead at the open end. The unitary cover comprises a central circular wall of a size corresponding to the container open end, a plurality of concentric rings surrounding the central circular wall and including a peripheral flange having a downwardly opening channel receivable on the cylindrical connecting bead to close the open end of the container, the peripheral flange having a substantially greater wall thickness than the central circular wall.
- It is a feature of the invention that the plurality of concentric rings comprises first and second concentric rings disposed between the peripheral flange and the central circular wall to define a generally corrugated structure.
- It is a further feature of the invention that the first concentric ring has a greater wall thickness than the central circular wall and the second concentric ring has a greater wall thickness than the second concentric ring and the peripheral flange has a greater wall thickness than the second concentric ring rib.
- It is still another feature of the invention that the peripheral flange has a diameter to be received on a tubular container having an, 18 inch, a 21½ inch or a 23 inch connecting bead.
- It is still a further feature of the invention that the cover comprises a unitary wall element of synthetic resin.
