The above mentioned typical pumping-type cosmetic container has features in that when a user pressurizes the button member, the pumping member positioned below becomes activated for thereby discharging contents stored in the container body through a discharge hole; however the pumping member has complicated constructions, and the manufacture costs a lot, and it is time-consuming.
Since the pumping member activates a pumping operation with the aid of a metallic spring, the metallic spring may corrode, which spoils the contents.
In order to improve the above mentioned problems, there is developed “a pumping device for a cosmetic container” whose Korean registered patent number is 10-0545007.
In the above mentioned Korean registered patent, the pumping device for discharging part of the fluid stored in the interior of the container comprises a pumping head 10 which is provided at the top of a head housing 20 while sealing it and ascends and descends along the inner surface of a head accommodation rib 22 for thereby depressurizing and pressurizing the fluid in the interior, the bottom of the pumping head 10 being open, and is equipped with a nozzle 11 through which to discharge the fluid of the interior to the outside and a discharge tube 12 which stands downward in the inner center for the purpose of supplying the fluid to the nozzle; a head housing 20 which covers the top of the container while sealing the same and air-tightly seal the open bottom of the pumping head 10 and is equipped with a bottom valve hole 21 at the center of which a bottom valve 60 is disposed, a head accommodation rib 22 being upright so as to air-tightly guide the bottom of the pumping head 10 which ascends and descends along an upper outer surface, a wrinkled tube accommodation rib 23 air-tightly sealing the bottom of the wrinkled tube 30 at the center of the upper surface being upwardly protruding from the outer side of the bottom valve hole 21, an engaging member 24 at an outer lower side being air-tightly engaged to the top of the container 70; an elastic wrinkled tube 30 which is contracted when the pumping head 10 descends and ascends the pumping head 10 by means of an elastic force when a descending pressure is removed, the top of which being air-tightly engaged to the bottom of the discharge tube 12 of the pumping head 10, the bottom of which being engaged air-tightly sealing the head housing including the bottom valve hole 21 of the head housing 30; a top valve housing 40 which air-tightly seal the end of the lower side of the discharge tube 12 of the pumping head 10, a top valve hole 41 passing through its center and to which the top valve 50 is engaged; a top valve 50 which is configured to open and close the top valve hole 41 of the top valve housing 40 and opens when the pressure of the interior of the wrinkled tube is higher than the pressure of the interior of the discharge tube 12 of the pumping head 10 and closes when the pressure of the interior of the discharge tube 12 is higher than the pressure of the interior of the wrinkled tube 30; and a bottom valve 60 which is configured to open and close the bottom valve hole 21 of the bottom valve housing 20 and opens when the pressure of the interior of the container 70 is higher than the pressure of the interior of the wrinkled tube 30 and closes when the pressure of the interior of the wrinkled tube 30 is higher than the pressure of the interior of the container 70.
