摘要： The present invention relates to a container stopper having a multi-lock structure in which a multi-lock structure is applied to the inner circumferential surface of an opening of a lower stopper, and to the outer circumferential surface of a sealing protrusion of an upper stopper coupled thereto, thereby preventing the coupled stoppers from being easily opened due to shock or other external force generated during the distribution process or storage of a product. To this end, the present invention provides a container stopper comprising: a lower stopper (110) which is coupled to an inlet (10) of a container (10); and an upper stopper (120) which allows an opening (111) provided within the lower stopper (110) to be selectively opened and closed, wherein at least two locking parts (130) are formed so as to be spaced apart from each other in the insertion direction on the inner circumferential surface of the opening (111) of the lower stopper (110) and on the outer circumferential surface of a sealing protrusion (121) of the upper stopper (120) coupled to the inner circumferential surface. The present invention as described above has the advantages of allowing the main locking position of the upper stopper coupled to the opening of the lower stopper to be formed so as to be inclined toward the end side of the sealing protrusion, thereby preventing the upper stopper from being easily opened by external shock, and also of improving the assembly strength of the upper stopper by applying the position of the locking parts to at least two points on the outer circumferential surface of the sealing protrusion.
