ABSTRACT:
A device is provided for removing and containing debris present in a fluid as the fluid moves through the device. The device includes a cover member attachable to an inlet pipe for receiving the fluid-carrying debris and an outlet pipe for removing the debris-less fluid. A receptacle is removably secured to the cover member while a replaceable trap bag is housed therein to contain the debris that is deposited by the fluid. The trap bag has a longitudinal seal portion which includes a flat seal portion to overlie a portion of the rim of the receptacle. A gasket member underlies the cover member to engage that portion of the trap bag which overlies the receptacle rim, including the flat seal portion. The flat seal portion substantially eliminates leakage of fluid along the longitudinal seal portion of the trap bag since there is virtually no difference in width between the flat seal portion and other portions of the trap bag overlying the rim. Consequently, there is a tight, uniform seal between the gasket member and the trap bag.
