发明名称 Dental filter with sanitary handling
摘要 A filter canister assembly for receiving waste from a dental cuspidor includes a canister of generally conventional configuration, with an open upper end fitted with a canister closure, the canister containing a closed disposable filter basket. A hand grip on the closed filter allows a dental technician to hold and dispose of the filter basket without contacting waste material contained within the filter.
