Abstract
A hermetically sealed container is provided with an overcap and a metamorphic spike carried therein for piercing a membrane on the container. The metamorphic spike is hollow and provides a liner that defines a controlled dispensing passageway. The spike pierces the membrane and is retained within the membrane after the overcap is removed so as to provide a controlled dispensing orifice for the container. The overcap can be reapplied to the container to seal the dispensing orifice.
