Abstract

The present invention relates to a dropper container, wherein the inner cap includes an inner cap skirt portion extending downward from the upper end of the inner cap side portion to face the outer cap side portion; the outer cap includes a spring support projection extending from the inner surface of the outer cap side portion toward a cylinder portion to be positioned above the inner cap side portion; the spring is installed in an uncompressed state between the spring support projection and the button ceiling surface portion such that when the outer cap rises, its lower end is pressed upward by the spring support projection and its upper end presses upward by the button ceiling surface portion; and the outer cap lifting action portion is formed separately on the outer cap side portion and the inner cap skirt portion and acts to raise or lower the outer cap relative to the inner cap according to the direction of rotation when the outer cap is rotated. By doing so, the lifespan of the spring can be stably maintained, and the upward movement of the button can be prevented from being obstructed by friction between the outer cap and the button.

Description

Dropper Container The present invention relates to a dropper container, and more specifically, to a container having a structure that discharges liquid contents stored in the container to the outside of the container through a pipette installed to enter the interior of the container. Liquid contents, such as cosmetics, are stored in a container and then gradually dispensed out of the container for use. Conventionally, as a type of container that discharges liquid contents stored in a container part little by little to the outside of the container part, a dropper container is used, which is a type that uses a pipette installed to enter the inside of the container part. The dropper container is used through the steps of: operating the liquid contents stored in the container to be sucked into the interior of a pipette installed to enter the interior of the container; and separating the pipette from the container and operating the liquid contents sucked into the pipette to be discharged to the outside. FIG. 10 is an exploded view of a conventional dropper container, and FIG. 11 is a cross-sectional view of a conventional dropper container. A conventional dropper container comprises a container portion (110) having a container side portion (111) and a container neck portion (113), an inner cap (120) having a cylinder portion (121) and detachably coupled to the container neck portion (113), an outer cap (130) having an outer cap side portion (131) and installed on the upper side of the container side portion (111), a piston (161) installed inside the cylinder portion (121), a button (140) having a button side portion (141) and installed on the upper side of the piston (161) so that the button side portion (141) is positioned between the outer cap side portion (131) and the cylinder portion (121), a spring (162) installed between the cylinder portion (121) and the button side portion (141) so as to be extendable along the longitudinal direction of the cylinder portion (121), and a spring (162) installed inside the container portion (110). It has a pipette (163), a button rise control unit (170) that restricts the upward movement of the button (140) before rotating the outer cap (130) and allows the upward movement of the button (140) when rotating the outer cap (130), and a wiper (164) and packing (165) installed on the top of the container neck (113). The container portion (110) has a container side portion (111) and a container neck portion (113), in addition to a container bottom portion (112) extending from the bottom of the container side portion (111). The container neck portion (113) extends upward from the top of the container side portion (111) so as to be positioned along a direction parallel to the container side portion (111). The inner cap (120) has, in addition to the cylinder portion (121), a tubular inner cap side portion (122) and an inner cap skirt portion (123) extending downward from the top of the inner cap side portion (122). The cylinder portion (121) extends upward from the top of the inner cap side portion (122) to form a concave shape. A contact hole (121a) is formed on the bottom surface of the cylinder part (121). The inner cap (120) is detachably coupled to the container neck (113) through the inner cap side portion (122) so that the contact hole (121a) is aligned with the container neck portion (113). The outer cap side portion (131) is formed in a tubular shape. The outer cap (130) is installed on the upper side of the container side portion (111) so that the outer cap side portion (131) surrounds the cylinder portion (121). The piston (161) is installed so that its outer surface contacts the inner surface of the cylinder part (121). The button (140) has, in addition to the button side portion (141), a button ceiling portion (142) extended from the top of the button side portion (141) in a direction perpendicular to the longitudinal direction of the button side portion (141), and a button fastening column (143) extended downward from the bottom of the button ceiling portion (142) in a direction parallel to the button side portion (141). The button side portion (141) is formed in a tubular shape. The button (140) is connected to the piston (161) through the lower end of the button connection column (143). The installation of the button (140) is such that when the outer cap (130) is at its lowest position, the button ceiling surface (142) is positioned at approximately the same position as the top of the outer cap side surface (131). The spring (162) is installed at both ends between the top of the inner cap side portion (122) and the bottom of the button ceiling portion (142), and between the cylinder portion (121) and the button side portion (141). The installation of the spring (162) is performed in a compressed state (a state in which elastic deformation occurs). The pipette (163) is installed so that its upper end communicates with the inside of the cylinder part (121) through the
