Watertight friction fit battery cap with cam removal

In a tool having a housing, said housing including a battery receiving area having an entrance, a motor located in the housing, a battery removably located in the receiving area in the housing, and an operating attachment extending from the housing and connected to the motor to be moved by the motor, wherein the improvement comprises:

• a battery cap frictionally mounted on the housing at the entrance to the receiving area, the housing having a trailing edge and the battery cap having a leading edge, said trailing and leading edges forming cooperating cam surfaces wherein, upon axial rotation of the battery cap relative to the housing, the battery cap is cammed away from the housing to assist in removing the battery cap from the housing.

In a cleaning apparatus having a housing, said housing including a battery receiving area having an entrance, a motor, a removable battery, and a removable cleaning attachment, wherein the improvement comprises:

• a battery cap frictionally connected to the housing at the entrance to the battery receiving area, the housing having a trailing edge and the battery cap having a leading edge, said trailing and leading edges forming mating edges, the trailing edge of the housing having circumferentially spaced cam surfaces and the leading edge of the battery cap having circumferentially spaced cam surfaces, said cam surfaces cooperating such that axial rotation of the battery cap in either clockwise or counter clockwise directions relative to the housing causes the battery cap to be cammed away from the housing by the cam surfaces.
