ABSTRACT OF THE DISCLOSURE A closure control for a storage box or the like having a heavy lid selectively movable between a closed position, wherein the lid closes an upwardly opening re- ceptacle for receiving tools and the like, and an open position wherein the lid extends upwardly from a rear wall of the receptacle to provide facilitated access to the in- terior thereof. Movement of the closure lid between the closed and opened positions is assisted by a sealed pneu- matic spring device. The spring device is arranged to pro- vide a controlled rate of extension. The spring device is mounted within the receptacle in such a manner as to be protected against damage from articles placed into the receptacle. In the illustrated embodiment, the spring is located at the rear corners of a parallelepiped receptacle. In the illustrated embodiment, wall structures are provided adjacent the spring to further protect the spring against injury from articles placed in the receptacle. The spring is arranged so as to cause a gentle lowering of the lid such as by inadvertent movement thereof from the open posi- tion to the closed position, thereby preventing injury to the user of the storage box.
