PURPOSE: To manufacture a hermetically sealed container without looseness provided with a closure insert fixed in a throat region integrated with a neck of the sealed container and preliminarily molded thereon and a removable overcap integrated with the throat region and having an easily breakable web on the perimeter as a contour. CONSTITUTION: A hermetically sealed container 10 includes a main body 12 terminating on a neck defining a throat region 14 and a removable overcap 16 having a web 18 integrated with the throat region 14 and easily breakable as a contour. A closure insert 20 formed of a cap 22 and a hollow main body 24 is stored in the throat region 14. The cap 22 is provided with a rib formed on the surface of its outer portion, and a part of the overcap 16 is formed in the cap 22. The cap 22 is brought into contact with the overcap 16 by the arrangement and can be removed with the overcap 16 in the case the breakable web 18 is cut off.
