Abstract

A container includes: a first container part for storing a given content therein; a second container part having couplers disposed on a top thereof in such a way as to surroundingly fix the outer peripheral surface of the first container part thereto; and a locking part rotatably coupled to the couplers in such a way as to surround the outer peripheral surfaces of the couplers, wherein each coupler has a pressurizer bent inward therefrom, if the locking part rotates in a first direction with respect to the couplers, to allow the outer peripheral surface of the first container part to be pressurizedly fixed thereto.

First claim

The invention claimed is:

1 . A container comprising:
a first container part for storing a given content therein; a second container part having couplers disposed on a top thereof in such a way as to surroundingly fix an outer peripheral surface of the first container part thereto; and a locking part rotatably coupled to the couplers in such a way as to surround outer peripheral surfaces of the couplers, wherein when the locking part rotates in a first direction with respect to the couplers, each coupler has a pressurizer bent inward therefrom to allow the outer peripheral surface of the first container part to be pressurizedly fixed thereto.

2 . The container according to claim 1 , wherein when the locking part rotates in a second direction opposite to the first direction with respect to the couplers, each pressurizer returns to their original position thereof to allow the pressurization against the first container part to be released, so that the first container part is separated from the couplers.

3 . The container according to claim 2 , wherein the locking part has guide portions protruding from an inner peripheral surface thereof and having slant surfaces formed in a horizontal direction on given regions thereof, and when the locking part rotates in the first direction, each pressurizer comes into close contact with the slant surfaces and move relative to the locking part, so that each pressurizer is bent inward from the couplers.

4 . The container according to claim 3 , wherein each pressurizer extends by a given length in the second direction from tops of the couplers.

5 . The container according to claim 4 , wherein the couplers comprise a first coupler and a second coupler spaced apart from each other to surround different regions of the outer peripheral surface of the first container part, and each pressurizer extends in the second direction from top of one side of the first coupler and from top of one side of the second coupler.

6 . The container according to claim 5 , wherein when the guide portions of the locking part are inserted into spaces between the first coupler and the second coupler, the slant surfaces are aligned with positions corresponding to each pressurizer.

7 . The container according to claim 4 , wherein the locking part has at least one or more guide protrusions protruding from the inner peripheral surface thereof, the couplers have at least one or more guide grooves concavely formed on the outer peripheral surfaces thereof in such a way as to correspond to the at least one or more guide protrusions, and when the locking part rotates, the at least one or more guide protrusions move along the at least one or more guide grooves to allow the locking part to rotate at a constant height.

8 . The container according to claim 7 , wherein each guide groove extends from one point of the outer peripheral surface of a corresponding coupler to one point of a corresponding pressurizer in a circumferential direction.

9 . The container according to claim 4 , wherein each coupler has a first locking projection formed on a bottom thereof, each guide portion has a second locking projection protruding from a bottom of the slant surface thereof, and when the locking part rotates in the first direction, each second locking projection of the locking part moves under each pressurizer and come into contact with end portions of the each locking projection to allow the locking part to be prevented from additionally rotating in the first direction.

10 . The container according to claim 9 , wherein the locking part has locking protrusions formed on the inner peripheral surface thereof in such a way as to be spaced apart from the guide portions by a given distance, and the couplers have locking grooves formed on outer peripheral surfaces of each first locking projection in such a way as to correspond to the locking protrusions, so that the locking protrusions are inserted into the locking grooves to allow the locking part to be prevented from arbitrarily rotating.

11 . The container according to claim 1 , further comprising a covering part detachably coupled to one side of the second container part in such a way as to rotate with respect to the second container part to open and close the second container part.

12 . The container according to claim 11 , wherein the second container part has a first hinge recessed inward from one side thereof, the covering part has a second hinge protruding from one side thereof in such a way as to be inserted into the first hinge, and when the second hinge is inserted into the first hinge, the covering part is detachably coupled to the second container part.

13 . The container according to claim 12 , wherein the first hinge comprises:
an incised portion recessed inward from the second container part; and at least one or more hinge protrusions protruding inward from the incised portion, and the second hinge comprises: a protruding portion protruding downward from the covering part; and at least one or more hinge grooves recessed inward from the protruding portion in such a way as to correspond to the at least one or more hinge protrusions, whereby when the second hinge is inserted into the first hinge, the at least one or more hinge protrusions, are fittedly coupled to the at least one or more hinge grooves to allow the covering part to be rotatable with respect to the second container part around the at least one or more hinge protrusions.

14 . The container according to claim 11 , wherein the covering part has at least a portion made of a transparent or semi-transparent material so that the given content stored in the first container part is seen from outside the container.
