I have had many reinforced Corpus containers that contained like affinity boost or credit boost for 30 min, but no Mantis part bp. Luckily I had Avionics drop from the first orokin container I ever found. But that container still remains the only one I have ever found. In my experience it seems that the Corpus container is the most common and the Grineer is next, leaving the orokin container the most rare.

There might be higher chance for the orokin containers to spawn on sabotage missions. At least I found one in the sabotage boss room where you need to get the key. I have smashed hundreds of containers in the void, but only there I found reinforced one. It was hidden out of sight, but you can easily scout the area with loot radar, which you would run anyway on sabotage missions.
