Abstract: The present invention relates to a foundation container comprising a discharge pump having a short working stroke and, more particularly, to a foundation container comprising a discharge pump having a short working stroke, the discharge pump having a short working stroke being configured such that a pump upper body, which has a content discharge port formed therein, is fitted to the upper portion of a pump main body, which has a content intake port formed therein, a pump inner body, which has an intake valve plate formed thereon, is fitted to insides of the pump main body and the pump upper body, a discharge valve wing of a discharge valve is coupled to a sealing protruding ring on the upper portion of the pump upper body, thereby vertically moving the pump upper body with respect to the pump main body, such that the volume of a temporary content storage unit of the pump inner body is changed, thereby discharging the content, the foundation container comprising a content diffusion plate formed integrally with an upper body upper plate of the pump upper body such that the content is discharged by a predetermined amount, diffused by the diffusion plate, evenly spread on a puff, and then used. The present invention provides a foundation container comprising a discharge pump having a short working stroke, the foundation container comprising an outer container main body (10); an outer container cap (20) coupled to the outer container main body (10) and opened/closed; a container main body (30) coupled inside the outer container main body (10); and a container cap (40) coupled to the upper portion of the container main body (30) and opened/closed, wherein the foundation container comprises a container interruption plate (34) coupled inside the upper portion of the container main body (30), a discharge pump (50) coupled to the center of the container interruption plate (34), and a content diffusion plate (60) coupled to the discharge pump (50); the discharge pump (50) comprises a pump main body (52), a pump upper body (54), a pump inner body (56), a discharge valve (57), and an elastic member (58); and the diffusion plate (60) is configured to extend to the pump upper body (54). The pump main body (52) has a content intake port (522) formed at the center of a main body lower plate (521), and the pump upper body (54) is coupled to the upper side of the pump main body (52) such that, by means of a vertical movement with respect to the pump main body (521), a pumping action is performed. The pump upper body (54) has a discharge valve coupling space (542) formed to be recessed at the center portion of an upper body upper plate (541), and a sealing protruding ring (544), which has a content discharge port (543) formed therein, is formed at the center of the discharge valve coupling space (542). The pump inner body (56) has a cylindrical shape, an inner body barrel wall (561) constituting the side surface thereof, an intake valve plate (563) is formed on the lower portion of the inside thereof and connected to an elastic piece (562), a vertical coupling piece (565) is formed on the upper portion of the inner body barrel wall (561) and connected to a horizontal connection piece (564), an upper side surface extension piece (566) is formed on the outside of the pump inner body (56) and connected to the upper end of the vertical coupling piece (565), and a lower side surface extension piece (567) is formed on the outside of the lower end of the inner body barrel wall (561). The discharge valve (57) is coupled to the discharge valve coupling space of the pump upper body (54), and a discharge valve wing (571) is formed inside the discharge valve (57) and is tightly coupled to the sealing protruding ring (544) of the pump upper body (54). The elastic member (58) is fitted outside the pump inner body (56) such that the lower end thereof is seated on the lower side surface extension piece (567) of the pump inner body (56), and the upper end thereof elastically supports the lower portion of the upper side surface extension piece (566), thereby both tensioning the pump inner body (56) vertically and elastically supporting the pump main body (52), to which the lower side surface extension piece (567) is coupled, and the pump upper body (54), to which the upper side surface extension piece (566) is coupled.
