1. A container stopper coupled to a container inlet of a container in which content is held, the container stopper comprising:
a stopper body that is coupled to the container inlet and has, on an upper side thereof, an auxiliary space in which auxiliary content having a granular structure is held; and
an upper cover that is coupled to the stopper body, forms the auxiliary space together with the stopper body, and covers the auxiliary space;
wherein the stopper body comprises:
a container coupling portion coupled to the container inlet; and
a cover coupling portion extending upward from the container coupling portion and coupled to the upper cover,
wherein the container coupling portion and the cover coupling portion are divided vertically by a partition wall portion coupled to an inner circumferential surface thereof,
wherein the upper cover and the cover coupling portion are provided with a sealing means for sealing the auxiliary space when coupled to each other,
wherein the sealing means comprises a cover inner ring that is in close contact with the inner circumferential surface of the cover coupling portion in a state in which the upper cover is coupled to the cover coupling portion,
wherein the sealing means comprises:
one or more first concave-convex portions formed at an upper end of the cover coupling portion; and
a second concave-convex portion which is formed at a lower end of the upper cover to be shape-fitted to and in close contact with the first concave-convex portions in a state in which the upper cover is coupled to the cover coupling portion, and
wherein the first concave-convex portions comprise a pair of protrusions that form a groove so that a protrusion of the second concave-convex portion is inserted.
