BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a wind decanter and more particularly, to a bottle-top wine decanter attachable to a bottleneck of a bottle of wine for decanting the wine of a bottle when the user is pouring the wine out of the bottle into a glass for service. 
         [0003]    2. Description of the Related Art 
         [0004]    When pouring a glass of wine, the wine may be splashed out from the glass if the bottle is excessively tilted, causing unnecessary waste and trouble. To solve this problem, wine pourers are created. However, a wine pourer can simply make serving wine a dripless event. When serving wine, an extra wine decanter may be necessary. Therefore, there is a strong demand for an apparatus that can serve as a wine pourer as well as a wine decanter. 
       SUMMARY OF THE INVENTION 
       [0005]    The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a bottle-top wine decanter, which uses alkaline filter components to filtrate the wine, enhancing the quality of the wine tasting. 
         [0006]    It is another object of the present invention to provide a bottle-top wine decanter, which works as a wine pourer, preventing splashing of the wine. 
         [0007]    It is still another object of the present invention to provide a bottle-top wine decanter, which keeps a cap press-fitted onto a stopper, enhancing component parts positioning stability. 
         [0008]    It is still another object of the present invention to provide a bottle-top wine decanter, which uses a magnetizer to activate the wine, making the wine easy to drink. 
         [0009]    To achieve these and other objects of the present invention, a bottle-top wine decanter comprises a wine-pouring tube carrying therein alkaline filter components for filtering wine, a breathing tube, a cap holding the wine-pouring tube and the breathing tube in parallel, a stopper mounted in the cap for press-fitting into a bottleneck of a wine bottle, and a magnetizer for activating wine to make the wine easy to drink.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0014]    Referring to  FIGS. 1-4 , a bottle-top wine decanter in accordance with the present invention is shown for decanting and aerating the wine of a bottle when the user is pouring out the wine onto a glass for service. The bottle-top wine decanter comprises a wine-pouring tube  1 , a breathing tube  2 , a cap  3 , and a stopper  4 . 
         [0015]    The wine-pouring tube  1  comprises a top wire mesh filter  11  and a bottom wire mesh filter  12  respectively and fixedly mounted in opposing top and bottom ends thereof, and a plurality of alkaline filter components  5  set therein between the top wire mesh filter  11  and the bottom wire mesh filter  12 . The top wire mesh filter  11  and the bottom wire mesh filter  12  each define therein a plurality of open spaces  111  or  121  (see  FIG. 2 ). Further, the alkaline filter components  5  can be selected from the group of alkaline ore, tourmaline and trace minerals. 
         [0016]    The breathing tube  2  is peripherally bonded to the periphery of a lower part of the wine-pouring tube  1  and inserted with the wine-pouring tube  1  through the cap  3  and then fixedly secured with the wine-pouring tube  1  to the cap  3 , keeping the bottom end  22  thereof suspending below the bottom edge of the wine-pouring tube  1  at a distance. 
         [0017]    The cap  3  comprises a circular top wall  30 , an insertion hole  31  cut through the top wall  30  for the mounting of the wine-pouring tube  1  and the breathing tube  2  in such a manner that the top end  21  of the breathing tube  2  can be exposed outside the top wall  30  of the cap  3  for breathing (see  FIG. 2 ), and a circular peripheral wall  32  downwardly extended from the circular border of the circular top wall  30 . 
         [0018]    The stopper  4  is made of an elastic material, such as rubber, silicone rubber or flexible plastics, comprising a top flange  40  press-fitted into the cap  3  and abutted against the bottom surface of the circular top wall  30  of the cap  3  and the inner surface of the circular peripheral wall  32  of the cap  3 , a first mounting through hole  41  and a second mounting through hole  42  respectively cut through opposing top and bottom ends of the stopper  4  and kept in communication with each other for the insertion of the wine-pouring tube  1  and the cap  3 , and a plurality of ribs  431  extending around the periphery  43  for press-fitting into a bottleneck of a wine bottle. After installation of the wine-pouring tube  1  and the cap  3  in the stopper  4 , the bottom end  22  of the breathing tube  2  suspends below the bottom end  421  of the second mounting through hole  42  at a distance. 
         [0019]    When the bottle-top wine decanter is assembled, the user can insert the stopper  4  into a bottleneck of a wine bottle, forcing the ribs  431  in friction engagement with the inside wall of the bottleneck of the wine bottle. When the user pours the wine out of the wine bottle, the wine will flow out of the wine bottle and the wine-pouring tube  1 . When the wine is flowing through the wine-pouring tube  1 , it will be decanted by the alkaline filter components  5 , enhancing the quality of the wine tasting. 
         [0020]    Referring to  FIGS. 1 and 4  again, the bottle-top wine decanter further comprises a magnetizer  6 . The magnetizer  6  comprises two magnets  61  and  62  arranged around the wine-pouring tube  1  at two opposite sides in a reversed manner, and a shell  60  covering the two magnets  61  and  62  and securing them firmly to the wine-pouring tube  1 . When pouring the wine, the magnetic field induced between the two magnets  61  and  62  activates the wine, making the wine easy to drink. 
         [0021]    In conclusion, the invention provides a bottle-top wine decanter, which has the advantages as follows: 
         [0000]    1. When pouring a glass of wine, the wine will be decanted by the alkaline filter components  5 , enhancing the quality of the wine tasting.
 
2. When pouring a glass of wine, the magnetizer  6  can activate the wine, making the wine easy to drink.
 
3. When pouring a glass of wine, the bottle-top wine decanter also works as a wine pourer, preventing splashing of the wine.
 
4. The circular peripheral wall  32  of the cap  3  is abutted against the periphery of the top flange  40  of the stopper  4 , enhancing positioning stability.
 
         [0022]    While only one embodiment of the present invention has been shown and described, it will be understood that various modifications and changes could be made thereunto without departing from the spirit and scope of the invention disclosed.
A bottle-top wine decanter includes a wine-pouring tube carrying therein alkaline filter components for filtering wine, a breathing tube, a cap holding the wine-pouring tube and the breathing tube in parallel, a stopper mounted in the cap for press-fitting into a bottleneck of a wine bottle, and a magnetizer for activating wine to make the wine easy to drink.
