Valve body for packaging container cap

Abstract

This product is a disk-shaped valve element that opens and closes in response to the pressure inside a squeeze container and is used by attaching it to the mouth of a squeeze container filled with contents. In the end view along line A-A' and the reference end view along line A-A', the valve element consists of an annular valve portion on the inner periphery, an annular seal portion on the outer periphery, and an annular partition portion formed integrally between the valve portion and the seal portion. The annular valve portion also has a groove (see the bottom view, end view along line A-A', and reference end view along line A-A', etc.). The reference end view showing the state in use is a reference view showing the valve element engaged with the inner cylindrical portion, the annular rib, and the cylindrical wall portion.
