Query: Leaks everywhere

This would be a great cup if it just didn't leak! I bought this for a trip to Disney World and before we had even completed the first leg of our flight it had leaked all over my daughter's diaper bag. I wish I had tested it out before we left! I have since tried to figure out if there was anything I am "doing wrong" assembling the cup but it continues to leak, leak, leak everywhere!
