Streszczenie
Let $\overline {b}(n)$ denote the number of overcubic partition pairs of $n$. Applying the theory of modular forms, Kim obtained two congruences for $\overline {b}(n)$ modulo $3$ and $64$. More congruences modulo $3$ and $5$ have been found by the first author of the present paper. In this paper, we proceed with the study of the congruence properties of $\overline {b}(n)$ and establish two infinite families of congruences modulo $9$.
