The invariants of each semigroup $T$ of this family are given in terms of the corresponding invariants of $S$ and the Ap\\'ery set and the minimal generators of $T$ are also described. We also study three properties that are close to the Gorenstein property of the associated semigroup ring: almost Gorenstein, 2-AGL, and nearly Gorenstein properties.
