I would not really do it, but if you really feel that you need to provide that syntax, you can write an inserter adapter...

template 
class inserter_type {
public:
   typedef C container_type;
   typedef typename container_type::value_type value_type;

   explicit inserter_type( container_type & container ) : container(container) {}
   inserter_type& operator<<( value_type const & value ) {
      container.push( value );
      return *this;
   }
private:
   container_type & container;
};
template 
inserter_type inserter( C & container ) {
   return inserter_type(container);
}
int main() {
   std::queue q;
   inserter(q) << "Hi" << "there";
}
