  • a first hollow part capped at one end thereof and formed with a protrusion on an outer diameter of the first hollow part, wherein said protrusion comprises a ring;

    a second hollow part having a punchable seal closing one end thereof and slidably receiving the first hollow part therein with the punchable seal axially opposite from the capped end to define an enclosed reservoir therebetween;

    the second hollow part comprising;

    a recess to receive the protrusion therein, the two hollow parts defining a first annular space therebetween sealed by engagement of the protrusion against the recess;

    a notched groove positioned on a wall of the recess and arranged in said inner diameter to receive said ring when the first hollow part is pressed into the second hollow part through the punchable seal; and

    an annular part disposed around and securely attached to the outside of the second hollow part to define a second annular space between the annular part and the second hollow part, the annular part formed with threads extending around an inner diameter of the annular part to threadably engage a bottleneck in the second annular space and dispose the punchable seal within the bottle; and

    a removable annular seal holding the two hollow parts in an axially fixed, spaced apart relationship and, upon removal of the removable annular seal, allowing the first hollow part to be pushed into the second hollow part for the first protrusion to be received in the second recess and the uncapped end of the first hollow part to dislodge the punchable seal.
