Claim:
An apparatus comprising: a compressor including an air pump and a tank configured to store air compressed by the air pump, the compressor being configured to be used while in an operating position in which the tank is in an upright position and has a rounded top surface and a vertical cylindrical side surface extending downward from the periphery of the rounded top surface; and a storage case configured to be removably mounted on top of the tank in a mounted position in which the case rests on the tank's top surface and engages the tank's side surface at locations selected so as to prevent the case from sliding off the tank's rounded top surface when a horizontal force in any horizontal direction is applied to the case urging the case to slide off the tank; wherein the apparatus lacks a latch or fastener for securing the case to the tank, for the prevention of the case slipping off the tank's rounded top surface to be due solely to the case's engagement of the tank's side surface, for the case to be brought into its mounted position by being simply lowered onto the tank and to be removed from its mounted position by being simply lifted upward from the tank without unlatching or unfastening.
