Pump container

A pump container comprising:

• a container body (10) for storing a liquid therein;
• a pump body (200) seatedly fitted to an inner peripheral surface of a top opening (11) of the container body (10) and having a cylindrical spring (260);
• a shoulder member (40) formed of a cylindrical member, having an open top and an open bottom, and having a screw portion formed along a lower inner peripheral surface thereof in such a manner as to be coupled to the top opening (11) of the container body (10) and an upper periphery (42) reduced smaller in diameter than a lower periphery (41) in such a manner as to fit a top end periphery of the pump body (200) thereto;
• and
• a discharge nozzle (50) insertedly fitted to the top end periphery of the pump body (200) in such a manner as to allow the pump body (200) to be operated by pushing the discharge nozzle (50) to discharge the liquid stored in the container body (10) to outside,
• wherein the cylindrical spring (260) is made of a plastic material and comprises:
• a top ring plate (261) having a hole formed at the center thereof;
• a first spring member (262) erectly extended downward from one side undersurface of the top ring plate (261), while rotating in a clockwise direction;
• a second spring member (263) erectly extended downward from other side undersurface of the top ring plate which is a position symmetrical to the one side undersurface thereof, while rotating in a same direction as the first spring member (262);
• and
• a pair of connection spring members (264 and 265) erectly extended downward from two center surfaces between one side undersurface and the other side undersurface of the top ring plate (261), while rotating in an opposite direction in a counterclockwise direction to the first spring member (262) and the second spring member (263), in such a manner as to be connected alternately to upper surfaces and bottom surfaces of the first spring member (262) and the second spring member (263).
