A thin film dispenser has a body, a moving assembly, a resilient positioning element, a dispensing unit and a push button. The body has an opening, a sliding channel and two sets of positioning recesses. The moving assembly is connected to the dispensing unit. The resilient positioning element is connected to the moving assembly and has a positioning segment selectively engaging one of the two sets of positioning recesses. The dispensing unit has a dispensing head corresponding to the opening of the body. The push button is mounted slidably in the sliding channel of the body, is connected to the moving assembly and selectively pushes against the positioning segment of the resilient positioning element to disengage from a corresponding set of positioning recesses to enable the moving assembly to move relative to the body.
