ABSTRACT:
The present invention relates to a dispensing closure which includes an automatic sealing valve which opens to dispense a fluid product from a squeeze-type container when the container is subjected to an external force, such as squeezing pressure, and which automatically closes when the external force is terminated, and a closure body which securely mounts the automatic sealing valve to the container, wherein the automatic sealing valve and the closure body are designed in a special form not to need a means for retaining the automatic sealing valve to the closure body, so that the possibilities of defect thereof in manufacture and disorder during use can be remarkably reduced, and the manufacturing cost can be reduced by shortening an assembling process.
