surface 12.
[0048] An opening 31 where the outer cap 10 is combined is usually
formed in a circular shape and the side 11 is also preferably
formed in a circular shape to be combined with the opening 31.
[0049] The outer cap 10 may further has a discharge guide 18 that
extends upward from the upper surface 12, around the discharge hole
13, in order to allow the liquid substance discharged through the
discharge hole 13 to stably flow to the outside.
[0050] FIG. 3A is a top view of an inner cap according to a
preferred embodiment of the present invention and FIG. 2B is a
cross-sectional view taken along the line B-B in FIG. 3A and an
enlarged view showing the main parts.
[0051] Referring to FIGS. 3A and 3B, the inner cap 20 is disposed
inside the outer cap 10 and has a body 21 and a protrusion 23.

container through the inlet/outlet holes 210 at the upper portion,
such that slosh of the substance does not occur, and accordingly,
the substance can be smoothly discharged and a desired amount of
substance can be discharged.
[0057] Further, since the protrusion 23 is formed not in a flat
surface, but a conical shape with the top cut (cone), the
inlet/outlet holes 201 can be more widely formed along the inclined
surface and the external air can more smoothly flow inside.
[0058] FIG. 4 is a cross-sectional view showing when the outer cap
