A valve and dispensing assembly for dispensing powdered material from a container includes a flexible tube intended to be collapsed to actuate a valve which permits the tube to selectively open for dispensing the material through the tube. The assembly includes a flexible tube apparatus including a body attachable to the container and a valve releasably received within the tube and normally closing it off. Collapse of the tube causes it to move relatively of the valve to unseat it and open the tube for material discharge. The assembly also includes a declumper secured to the tube for movement therewith during collapse of the tube. The valve closes off the tube when in its uncollapsed condition while the tube and declumper move relatively of the valve during collapse to open the tube. A portion of the declumper is bifurcated and has serrated opposed edges which can engage the head of the valve during the tube collapse to assist in breaking up clumps which may have formed in the material.
