Abstract:
A sock or bag-type liquid filtering device for use in filtering liquids such as water to remove debris includes a sock or bag of disposable filter material having a rim releasably secured to a two part filter holder. In one embodiment, the holder is designed to engage in an opening of a fish tank filter plate with the filter bag extending through the opening. A first holder part or flanged ring engages inside the rim of the bag and a second holder part or retainer ring engages over the flanged ring and bag rim. In one example the retainer ring is designed for snap engagement over the flanged ring with gripping formations on at least one of the parts, and the bag rim is gripped between the rings.

Claim (Index 12):
A method of assembling a filter device, comprising:\n engaging a central opening in a flanged ring over a mandrel of smaller diameter than the central opening, and sliding the ring along the mandrel until a flange at one end of the ring is seated on an enlarged base at a first end of the mandrel; positioning a central portion of a disposable filter sheet over a second end of the mandrel; engaging a retainer ring having a central opening over the mandrel and filter sheet to trap the filter sheet between the mandrel and retainer ring; moving the retainer ring along the mandrel up to the flange to form the filter sheet into a filter bag around the mandrel; releasably securing the retainer ring to the flanged ring to form a filter holder with a peripheral rim portion of the formed filter bag gripped between opposing surfaces of the rings; and sliding the assembled filter holder and filter bag off the mandrel.
