Abstract

Disclosed is a stopper and a container having the same including a stopper body including an upper part having a discharge hole, and a side part, having at least a dual structure, including an inner part and an external part which are spaced apart from each other and a coupling portion coupling the inner part and the external part at a top of the inner part and the external part, wherein the side part may include a first protrusion at the top of the inner part, a first groove at the coupling portion and a second protrusion between the first groove and the external part.

First claim

The invention claimed is:

1. A stopper, comprising:
a stopper body comprising an upper part having a discharge hole and a side part having at least a dual structure including an inner part and an external part and a coupling portion coupling the inner part and the external part at a top of the inner part and the external part, wherein the inner part and the external part are spaced from each other;
wherein the side part comprises a first protrusion at the top of the inner part, a first groove at the coupling portion and a second protrusion between the first groove and the external part;
wherein the first protrusion protrudes in a direction towards the external part from a top of a side surface facing the external part; and
wherein the first protrusion has at least a dual structure including a first step portion and a second step portion.

2. The stopper of claim 1 , wherein the second protrusion protrudes in a direction towards a bottom from a surface of the coupling portion.

3. The stopper of claim 1 , wherein the first and second protrusions are coupled to each other via the first groove.

4. The stopper of claim 1 , wherein the external part comprises a third protrusion protruding in a direction towards the inner part from a bottom of a side surface facing the inner part.

5. A container comprising:
a container body having an inlet at an upper part which is open; and
a stopper configured to be coupled to the inlet,
wherein the stopper includes an upper part having a discharge hole and a side part having at least a dual structure including an inner part and an external part such that the inlet is inserted therebetween,
wherein the side part includes a first protrusion protruding from a top of the inner part so as to be coupled to a top of an inner surface of the inlet, a first groove between the inner part and the external part so as to be coupled to a top surface of the inlet and a second protrusion between the first groove and the external part so as to be coupled to a side surface of a top of the inlet at the first groove.

6. The container of claim 5 , wherein the inlet includes a first stepwise part at the top of the inner surface.

7. The container of claim 6 , wherein the first protrusion has a stepped structure corresponding to the first stepwise part.

8. The container of claim 5 , wherein the inlet includes a second stepwise part at a top of an external surface.

9. The container of claim 8 , wherein the second protrusion is coupled to the inlet at an upper part of the second stepwise part.

10. The container of claim 5 , wherein the external part of the stopper body includes a third protrusion protruding from a bottom of the external part so as to be coupled to a bottom of an external surface of the inlet.

11. The container of claim 10 , wherein the inlet includes a groove portion at the bottom of the external surface to receive the third protrusion.

12. The container of claim 5 , wherein the inlet further includes a third stepwise part protruding from a lower part of a region where the external part of the stopper is located.
