Abstract

The present invention relates to a tube-type cosmetic container for discharging liquid contents in a droplet form, the container having a sealing member, which is coupled to the inside of an overcap and has a sealing protrusion for closing a discharge hole of a contents discharge tube, and pulling a sealing cap downward by the tensioning of an elastic supporting body so as to maintain a state in which the sealing protrusion further comes in close contact with the inner wall of the content discharge tube, when the overcap rotates such that the sealing member is coupled to a discharge part, thereby enabling the leakage of contents to be efficiently prevented regardless of an injection deviation and an assembly deviation between components.

First claim

The invention claimed is:

1. A liquid contents discharge container, comprising: a container body storing contents;
a container neck disposed at an upper portion of the container body and provided with a discharge part for discharging the contents stored therein;
a contents discharge tube which is coupled to an upper portion of the discharge part and having a discharge hole formed at an upper end thereof for discharging contents to the outside;
a sealing member encasing the contents discharge tube and detachably coupled to the discharge part, and comprising a sealing cap provided with a sealing protrusion for sealing the discharge hole of the contents discharge tube when the sealing member is coupled to the discharge part; and
an overcap coupled, encasing the sealing member to rotate the sealing member by a user's manipulation;
wherein the sealing member further comprises:
a coupling part coupled to the overcap so as to rotate the sealing member together with rotation of the overcap;
a coupling tube extending upward from a central portion of the coupling part and screw-coupled to the discharge part; and
a plurality of elastic support bodies which are extended in a spaced apart at regular intervals from an upper portion of the coupling tube, and elastically support the sealing cap.

2. The liquid contents discharge container of claim 1 ,
wherein, when the sealing member is coupled to the discharge part by rotating the overcap, an angle of the sealing cap is changed by the tensioning of the elastic support bodies, and the sealing protrusion is configured to be flexibly inserted into the discharge hole of the contents discharge tube.

3. The liquid contents discharge container of claim 1 ,
wherein the sealing protrusion is configured to be closely contacted to an inner wall of the contents discharge tube by a force of pulling the sealing cap downward according to the tensioning of the elastic support bodies in a state inserted into the discharge hole of the contents discharge tube so as to provide a sealing function.

4. The liquid contents discharge container of claim 1 ,
wherein at an outer circumferential surface of the coupling part is provided with a guide protrusion to guide coupling to the overcap, and at an inner circumferential surface of the overcap is provided with a coupling groove coupled to the guide protrusion.

5. The liquid contents discharge container of claim 1 ,
wherein at an outer circumferential surface of the coupling part is provided with a detachment prevention protrusion so as to prevent the overcap from detaching due to movement thereof in an upward direction in the state in which the overcap is coupled, and at an inner circumferential surface of the overcap is provided with a support protrusion supported by a lower end of the detachment prevention protrusion.

6. The liquid contents discharge container of claim 1 ,
further comprising, a discharge amount adjustment part provided with a discharge amount adjustment tube that becomes wider from a lower portion to an upper portion thereof so that discharge amount is adjusted when contents discharged through the discharge part move to the upper portion thereof.
