Description

  The present invention relates to a pump.

  As a pump that attaches to the container body and pumps out the liquid in the container body, it is attached and fixed to the container body with a mounting cap, and is mounted so that it can be moved up and down in an upward biased state with respect to the cylinder. Various types have been proposed which include an actuating member and pump up and discharge the liquid in the container body by the vertical movement of the actuating member. (For example, see Patent Document 1)

  The pump includes a first check valve that unilaterally flows from the container into the cylinder at the bottom of the cylinder. In addition, the operating member is configured by mounting an annular piston that can be moved up and down relative to a stem that is fitted to the upper end of the discharge head and mounted in the cylinder in an upwardly biased state. The annular piston constitutes a second check valve that unilaterally flows from the cylinder into the stem.
