Abstract

The present invention relates to a spuit-type cosmetic container. The spuit-type cosmetic container, according to the present invention, comprises: spiral grooves for guiding the ascending and descending operations of a piston rod on both sides of an inner cap; and guide protrusions which move along the spiral grooves on both sides of the piston rod such that the piston rod ascends and descends along the spiral grooves of the inner cap. Thus, the present invention can prevent a sudden discharge of the content by minimizing the pressure caused by a piston.

First claim

What is claimed is:

1. A spuit-type cosmetic container comprising:
a container body, wherein content is contained, and wherein a coupling part equipping a first screw thread which encircles outer circumferential surface on the upper portion is provided;
a spuit pipe suctioning content held in the container body;
an applicator part coupled on the lower portion of the spuit pipe and discharging content;
an inner cap comprising a body, wherein a second screw thread couples with screw combination to the first screw thread of the container body on the inner circumferential surface, and an ascending and descending guide part which extends from the upper end to the upper portion of the body and comprises a pair of spiral grooves on both outer circumferential surfaces;
an ascending and descending member, further comprising a piston rod, wherein a piston is coupled so as to guide content to be suctioned or discharged by changing pressure in the spuit pipe of its end while ascending and descending inside of the inner cap, and a guide protrusion built on both outer circumferential surfaces and moving along spiral grooves in the inner cap;
a button part, coupled to the upper portion of the ascending and descending member and delivering pressure by a user's pressurizing to the ascending and descending member; and
an outer cap coupled to be able to rotate, encircling the inner cap, comprising a hollow cavity, and forming a perpendicular guide groove at an inner circumferential surface thereof which guides a perpendicular movement of the guide protrusion,
wherein a pair of depression parts, sunken to the inner side direction, are formed at both sides of an outer circumferential surface of the body of the inner cap to be able to limit an independent rotation range of the outer cap, and
wherein a pair of rotation protrusions are formed at an inner side of the outer cap, the rotation protrusions rotatable inside the depression parts.

2. The spuit-type cosmetic container of claim 1 , wherein the applicator part further comprises:
a steel ball touching a user's skin and discharging content by its rotation;
a ball support body coupled to the lower portion of the spuit pipe and forming space for the steel ball to rotate; and
a ball cap coupled to the end of the ball support body and preventing the steel ball from being separated.

3. The spuit-type cosmetic container of claim 1 , wherein the button part comprises:
a button coupled to the upper portion of the piston rod; and
a button cap coupled to the hollow cavity of the outer cap, and built as encircling the button, and delivering pressure to the button.

4. The spuit-type cosmetic container of claim 1 , wherein a securing part secured on the upper end of the container body is built on the upper end of the spuit pipe, and a gasket is coupled on the lower end of the securing part.
