PROBLEM TO BE SOLVED: To limit excessive discharge of a liquid by constituting a closure in a neck in front of a container body of a thick portion and a thin portion formed radially from the center and by forming a discharge port with the thin portion torn by sticking a needle pin through the closure. SOLUTION: A closure 3 at a tip of a neck 2 fixed in front of a container body 1 comprises a thick portion 4 and a thin portion 5. The thin portion 5 is formed to be radially outward from the center. The number of the thin portions 5 is preferably two or more, and in the case of two or more, the portions 5 may be lines passing through the center. The number is further preferably three or more. By sticking a needle pin through the closure 3, the thin portions 5 may be torn. When the needle pin is removed, a slit-like discharge port can be formed. Thus the formed discharge port may be slit-like, wherein passage of liquid can be limited in this portion, so that an amount of discharged liquid can be regulated. Therefore, excessive discharge of the liquid can be prevented as much as possible. |
