A closure assembly is provided which is mounted on the end of a collapsible tube or pouch dispenser through which liquid or soft solid substances such as toothpaste, shaving cream, catsup, mustard, shampoo, glue, and the like, may be dispensed. The closure assembly allows the particular substance to flow through it only when the tube is squeezed, and it automatically closes to prevent further flow of the substance when the squeezing pressure is removed. The closure member includes a tubular tip mounted on the mouth of the collapsible tube. The distal end of the tip is flattened, and an opening is provided on one or both sides of the flattened end of the tip, with the opening extending into the interior of the tip. A flexible open-ended sleeve is drawn over the flattened end of the tip and over the opening, and the sleeve normally exhibits a closed slit at its distal end to seal the opening and to maintain the particular substance in the tube. However, when a squeezing pressure is applied to the collapsible tube, the substance in the tube is forced through the openings in the tip, and between the flattened end of the tip and the sleeve, to be dispensed through the slot at the end of the sleeve so long as the squeezing pressure is applied.
