Abstract

PROBLEM TO BE SOLVED: To prevent a liquid from scattering when a cap is closed and allow the liquid to well drain off at the time of finishing the pouring of the liquid. SOLUTION: When a cap 4 is closed to a pouring part 3, an edge portion 4b on a lower face of the cap is arranged so as not to be brought into contact with an edge portion 3e on an upper face of the pouring part, thus preventing a liquid from scattering. A closed state of the cap 4 can be kept by the engagement action of an engaging protrusion 1a formed in a pouring hole 1 with a protrusion 2a formed on a stopper 2 which is a part of the cap 4. Further, by making the inner diameter of the hole 1 on the outflow side larger than that on the inflow side, the liquid remaining in the vicinity of an outlet of the hole 1 is made easier to be returned to the interior of a container when the pouring of the liquid is finished, thus allowing the liquid to well drain off.
