ABSTRACT:
A suction canister particularly suitable for the collection of waste fluids from a medical patient including an open-top receptacle and a lid adapted to close the open-top of the receptacle. The receptacle and lid are each readily and inexpensively moldable from plastic materials employing existing molding techniques and facilities. The outer rim of the open top of the receptacle and the peripheral margin of the lid are adapted to provide engagement of the lid with the rim of the receptacle, such engagement providing a positive and readily identifiable limit of the extent of the engagement that provides a certain sealing of the id with the receptacle rim, and resulting in an interlocking of the lid with the receptacle as prevents removal of the lid from the receptacle other than by destructive force applied to the lid and/or receptacle.
