Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
74 words
A liquid collecting and retaining member for use in the treatment of liquid spills comprising a tubular casing member of thermoplastic, non-woven, absorbent material that is porous to liquids but substantially non-porous to granular solid matter, said casing member having a triangular cross-section, a filling material contained within said casing, said filling material being capable of collecting and retaining liquid that passes through said casing, and means closing the ends of said casing member.
Claim 2
Dependent Claim
74 words
A liquid collecting and retaining member for use in the treatment of liquid spills comprising a tubular casing member of thermoplastic, non-woven, absorbent material that is porous to liquids but substantially non-porous to granular solid matter, said casing member having a triangular cross-section, a filling material contained within said casing, said filling material being capable of collecting and retaining liquid that passes through said casing, and means closing the ends of said casing member.
