A hermetically sealed container is provided with a neck portion having an end wall defining a container contents-dispensing aperture therein. The aperture is closed with a removable cap structure connected with a frangible web unitary with the end wall and cap so as to seal the container contents-dispensing aperture. An overcap is rotatably mounted on the container and has a cage for matingly engaging the cap and is adapted to break the frangible web when the overcap is rotated.
