<P>PROBLEM TO BE SOLVED: To provide a dispensing head for a foam dispense container from which liquid contained in a container body 80 having the ejection head mounted thereon is dispensed as foam by mixing the liquid with external air to foam the liquid, and which has a nozzle solidification prevention mechanism for preventing the liquid remaining in the nozzle from being solidified. <P>SOLUTION: The dispensing head includes an umbrella-shaped valve body B formed of an elastic material and provided at an end of a nozzle 14. The umbrella-shaped valve body B includes: a fitting tubular portion 21 fitted and secured at an outer periphery of a support rod 34 supported at the center of a flow path p such that bubble can flow therethrough; and a valve plate 20 having a tapered shape extending from an outer surface of the fitting tubular portion 21 and widening toward the front, and for closing the flow path p by pressing an end thereof against an inner surface of a tubular inner wall of the flow path p, and thus allowing bubble to be dispensed by elastic deformation toward the center side by the inner pressure produced when a bubble dispensing operation is performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
