Abstract:
The present invention relates to a cap assembly configured to be attached to a container, the cap assembly comprising: a top cap which includes a rest position and a pressable position; a piston rod connected to the top cap, the piston rod being connected to a piston at the bottom to actuate the piston to move vertically, the piston rod further comprising an inclined upper guiding surface; a deformable element bearing at the top end against the upper guiding surface of the piston rod so that the deformable element is movable along the upper guiding surface; a support which is vertically movable to move the top cap from the rest position to the pressable position, the support including an inclined lower guiding surface against which the bottom end of the deformable element is supported so that the deformable element is movable along the lower guiding surface; when the top cap is pressed, the piston rod moves downwards and actuates the piston to move downwards to dispense material from a dispensing chamber while forcing the deformable element to deform from an initial state and to move along the upper guiding surface and the lower guiding surface; and when the top cap is released, the deformable element returns to the initial state.
