In a closure for a squeeze container, a first valve component is provided which includes an integrally formed membrane and central stem, and a second valve component is provided which includes a tubular dispensing spout. The first and second components are snap-assemblable so that the stem and membrane are fixed concentrically within the tubular dispensing spout so that a periphery of the inverted membrane annularly contacts a wall of the spout. This causes a radially-directed sealing bias is formed between the inverted membrane and the spout. |
