Patent ID: 6902304

Claim:
A stopper comprising: a hyaline head having a bottom formed with a cave; an electrically conductive tubular coupling fitted in said cave and having a top formed with a receiving port, said coupling having a lower portion formed with external threads; an insulated ring fitted in said tubular coupling; a buffer ring fitted over said lower portion; a plurality of batteries fitted in said insulated ring; light emitting means including a circuit board, a plurality of illuminants deposited on said circuit board, a dividing sheet deposited on a bottom of said circuit board, a first lead in contact with an inner side of said electrically conductive tubular coupling, and a second lead extending through said dividing sheet; an embedding member having a recess with an open top, said recess being threaded to engage with external threads of said lower portion of said electrically conductive tubular coupling; and a conical insertion having a cavity configured to receive said embedding member and having a plurality of check rings; whereby when said conical insertion is inserted into a bottle and said hyaline head is turned to compress said buffer ring, said batteries will be in contact with said second lead thereby forming a closed circuit and therefore causing said illuminants to give light, and when said hyaline head is turned to release said buffer ring, said batteries will not be in contact with said second lead thereby turning off said illuminants.
