Abstract
A cream-state fluid container having a body capable of being reduced in interior volume by evacuating the interior thereof in negative pressure, a head mounted at the top of the body and having a pushbutton and a filling port, a pump unit internally mounted in the head and operated by the pushbutton of the head for discharging the content of the body to the filling port of the head, the pump unit having a valve mechanism including a suction valve and a discharge valve in such a manner that a valve body is seated on a cylindrical valve seat formed in the head, a pressure chamber formed in a space from the valve mechanism at the position above the valve mechanism, and an elastic cap capable of being elastically deformed by depressing the cap by the pushbutton. Thus, the wasteful loss of cream-state liquid can be eliminated in discharging the liquid from the container.
