Abstract:
1. An apparatus comprising: an outer shell, comprising a cylindrical hollow interior and an engagement portion; an inner shell, comprising a cylindrical exterior smaller than the cylindrical hollow interior of the outer shell and a hollow threaded interior for threaded engagement with a bottle top; wherein the inner shell is movably attached to the cylindrical hollow interior of the outer shell, such that rotation of the outer shell causes the outer shell to rotate with respect to the inner shell for a limited range before the engagement portion of the outer shell engages the inner shell, whereby the inner shell is caused to rotate in concert with the outer shell; a printed circuit board, provided between the cylindrical hollow interior of the outer shell and the cylindrical exterior of the inner shell providing a circuit; a contact switch, including a compressible contactor portion and a contact pad, both affixed to the same one of either the inner or outer shell; an actuator, fixedly attached to whichever of the inner or outer shell the contactor portion and contact pad are not affixed to, wherein the rotation of the outer shell relative to the inner shell causes the actuator to compress the compressible contactor portion into contact with the contact pad as either the compressible contactor portion and the contact pad are rotated towards the actuator or the actuator is rotated towards the compressible contactor portion and the contact pad, thereby activating the circuit; a resilient, flexible spring, engaged by both the inner and outer shell, wherein the rotation of the outer shell relative to the inner shell causes the spring to deform, storing energy, and wherein the energy is sufficient to cause rotation of the inner shell relative to the outer shell, moving the actuator to a position wherein the compressible contactor portion is uncompressed, thereby deactivating the circuit, once the bottle top has been removed from a bottle and the energy is released; and a speaker, connected to the printed circuit board and operable to play sound when the circuit is activated.
