  A partition of $n$ is $l$-regular if none of its parts is divisible by $l$.
Let $b_l(n)$ denote the number of $l$-regular partitions of $n$. In this paper,
using theta function identities due to Ramanujan, we establish some new
infinite families of congruences for $b_l(n)$ modulo $l$, where $l=13,17,23$.
