  • Patent number: 7896185
    Abstract: A molded plastic container, such as a five gallon pail, that includes a lid and main body that are selectively attachable to each other without a resilient gasket. The main body of the plastic container includes a flexible sealing finger formed along the top rim of the main body. The flexible sealing finger is received within a sealing chamber formed as part of the rim. The sealing chamber is defined by a gland seal such that when the lid is attached to the main body, both the flexible finger and the gland seal can deflect to create multiple sealing points between the flexible sealing finger and the sealing chamber. A latch ring is formed on the outer surface of the main body and engages a locking tab formed on the lid to hold the flexible finger in the sealing chamber.

  • Patent number: 6964348
    Abstract: A molded resilient plastic container, such as a paint can, that includes a rim assembly to facilitate the receipt and removal of a plastic lid. The rim assembly is adhesively attached to the main body of the container and includes an annular channel that receives a portion of the lid. The annular channel is defined at its inner edge by a flexible finger having a locking tab that engages a corresponding locking notch formed on the lid to lock the lid onto the rim assembly. The container includes a specifically designed bottom having a projecting annular flange that can be received in an annular space formed along the top edge of the container between the lid and rim assembly when the lid is attached to the rim assembly. The container bottom also includes a projecting support leg that further supports the container when the containers are stacked on top of each other.
