std::vector of std::tuples leads to unknown size

I want to store three arbitrary ints inside a std::vector without defining a struct/class. So I went for std::tuple<>:

std::vector<std::tuple<unsigned int, unsigned int, unsigned int> 

Using MS VS 2013, it leads to the following error:

>c:\program files (x86)\microsoft visual studio 12.0\vc\include\vector(1628): error C2036: 'std::tuple<unsigned int,unsigned int,unsigned int> *' : unknown size

Is this due to limitations in the MSVS2013 compiler? Or am I doing something wrong?
