A vessel having a cover connected thereto by a unique hinge contains a basket supported filter bag for filtering liquid under pressure that enters the mouth of the bag through an inlet in the cover and is discharged through an outlet in the bottom of the vessel. The hinge is provided with a liquid inlet passage which communicates with a liquid supply plumbing connection which is permanent and need not be disturbed when the cover is arriving open, or closed. The cover contains a manifold that serves not only as a liquid inlet, but also as a handle. Annular seals caused by the rim of the basket are located on the annular wall of the body of the vessel so that when the cover is simply closed and clamped, leakage of the pressurized liquid is prevented above the bag, as well as from the vessel itself.
