A closure shell has an end wall and a sidewall. The sidewall has an inside thread for engagement to a thread formation of a container neck. The closure shell has a sealing flap extending radially from the sidewall and an annular vertical member extending from the end wall. The vertical member has an inside diameter greater than the diameter of a seal finish of the container neck. The sealing flap is sized and arranged to be pressed axially by the seal finish to the end wall, and radially pressed by the seal finish to the vertical member. A resilient element is formed between the vertical member and the sidewall to radially press the vertical member against the sealing flap to effect a tight radial seal. |
