Plastic container having a gasketless seal

摘要

A molded plastic container (10), such as a five gallon pail, that includes a lid (14) and main body (12) that are selectively attachable to each other without a resilient gasket. The main body of the plastic container includes a flexible sealing finger (48) formed along the top rim of the main body. The flexible sealing finger is received within a sealing chamber (92) formed as part of the rim. The sealing chamber is defined by a gland seal (90) 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 (58) is formed on the outer surface of the main body and engages a locking tab (84) formed on the lid to hold the flexible finger in the sealing chamber.
