Abstract
Abstract The invention relates to a closure for collapsible tubes, particularly for those containing tooth paste, the closure being designed to dispense toothpaste directly onto a tooth brush. The new closure comprises an elongated body having a longitudinal bore which is provided with an internal screw thread fitting onto the screw threaded neck of a tube, the said bore being curved and ending in a branch the axis of which is substantially normal to the axis of the main bore, a hinged lid being provided to close onto the opening in the said branch of the bore. In a preferred embodiment of the invention the said branch of the bore ends in the center of a wart like protrusion, while the said lid had a depression into which the said wart like protrusion can enter. The lid is urged into closing position by means of a spring.
