PURPOSE:To provide a hermetic container of synthetic resin which is easy to fill with liquid and whose mouth can be sealed perfectly. CONSTITUTION:At the mouth 2 of a container an inlet part 12 having a larger diameter than the inside diameter of the mouth is formed; an elastic stopping material 6 is inserted in the inlet part and the mouth of the container is closed by this stopping material. On the other hand, for the bottom 3 of the container a hollow bottom wall 13 which caves into the container is formed so as to leave a space at the bottom of the container. On the hollow bottom wall a filling hole 4 which is fused after filling the container with a liquid is formed; the fusion makes the filling hole a sealing part 14. |
