The present invention relates to a pump of a cosmetics case that enables smooth pumping by improving the structure of a check valve. Existing pumps of cosmetics cases have a problem that the pumps do not rise or fall vertically in a long-term usage and pumping is not performed smoothly. To solve the problem, the present invention provides a pump of a cosmetics case having a stem inserted therein, wherein the stem has a check valve combined inside a housing and has a piston combined on the outer circumference. The check valve comprises: a hanging part fixed inside the housing; and an axis part connected to the middle of the hanging part by a plurality of connection parts to be extended downward. Therefore, the present invention closely seals the lower entrance of the housing by the load of the downward extending axis part of the check valve, enables smooth pumping by rising and falling along a guiding part, and thus operating accurately vertically without floating from side to side, and thus does not cause worry about malfunction even in a long-term usage. |
