the pic above shows the cup Ruka bought in first ep. Which eventually became Takeru's cup. As you can see, the handle is broken.
This one showed the cup again, when Takeru tried to return it to Ruka, who doesn't want it anymore becoz of the crack....
this one was from ep9, final scene where it broke and fell down, but in one whole piece. we can't get a CLEAR picture but obviously, they used a different cup.
oh someone pointed this out in d-addicts forum

Look at the calender , it says 6th June 2008. Which was last Friday, a day AFTER the show was shown in Japan. It's like going to the future xD
