  For a multiplier Hopf algebra pairing $\langle A, B\rangle$, we construct a
class of group-cograded multiplier Hopf algebras $D(A, B)$, generalizing the
classical construction of finite dimensional Hopf algebras introduced by
Panaite and Staic Mihai. Furthermore, if the multiplier Hopf algebra pairing
admits a canonical multiplier in $M(B\otimes A)$ we show the existence of
quasitriangular structure on $D(A, B)$. As an application, some special cases
and examples are provided.
