摘要： 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.
摘要翻译：一种奶油状流体容器，其具有能够通过以负压抽空其内部而能够减小内部体积的主体，安装在主体顶部并具有按钮和填充口的头部，内部安装在主体内的泵单元头部并由头部的按钮操作，用于将本体的内容物排放到头部的填充口，泵单元具有包括吸入阀和排出阀的阀机构，使得阀体位于形成在头部中的圆柱形阀座，在阀机构上方位置处形成在阀机构的空间中的压力室，以及通过按压按压盖可弹性变形的弹性帽。因此，在从容器排放液体时可以消除奶油状液体的浪费的损失。
