around the perimeter that extend beyond the inside wall of the first member cylinder 12 the interior of first member 12 includes an extended lip 18 that prevents the second member 20 from being pushed beyond the upper lip 22 when the second member 20 is inserted at the factory into first member 12 the annular lip which extends inwardly 18 on the inside wall of cylinder first member 12 is a stop when the device is activated by depressing the second member 20 downwardly to puncture the bottom wall 12 b of first member 12 to dispense the ingredients lip 22 on member 20 prevents the entire element 20 from being pushed into a liquid in the bottle because of lip 18 however the inside wall of first member 12 also includes a groove 12 c that engages lip 22 to seal the unit at the factory referring now to fig2 the first member is shown inverted in order to show the perimeter area near the bottom 12 b that has the weakened area 12 a which allows the pointed prongs 24 and 26 on the second member to sever areas of the bottom 12 b from the first member cylindrical body 12 which allows the ingredients to be dispensed into a bottle additional prongs could be added on either side of prong 24 and prong 26 the annular lip 14 extends.
