A spring mechanism comprising an elongate cantilevered spring member 100 extending along a longitudinal coupled at a first end to a first member and with a distal, second end of the spring member 102 engaging a second member such that the spring member biases the first and second members relative to each other. The spring member has an unbiased condition and being resiliently deflectable generally normal to its longitudinal to assume deflected conditions from which the spring member inherently attempts to return to its unbiased condition. The spring member preferably consists of plastic material and may be formed as an integral element injection molded from plastic as a unitary element together with the first member to which it is coupled. Also disclosed is a dispenser unit adapted for single use and preferably secured to a wall with a reusable wall plate. The dispensing unit is preferably an assembled unit which, as a unit, is mountable to and removable from the mounting plate. For dispensing a flowable material such as soap. |
