发明名称 Blackboard eraser apparatus
摘要 An apparatus including a lid removably mounted relative to an underlying container, wherein the lid includes a first and second trough spaced juxtaposed to a central trough, wherein the central trough includes an apertured floor, and the first and second troughs are each arranged for selective securement of fluid therewithin. A sponge assembly includes a plate member to overlie the first and second troughs mounting a sponge to the bottom surface of the plate member. The sponge is defined by a sponge height less than a first trough height of the first and second troughs, wherein a second trough height of the central trough is less than the sponge height to permit compression of the sponge within the central trough and removal of excess fluid therefrom. A serpentine handle is mounted to a top surface of the support plate for enhanced manual grasping of the eraser member.
