Was playing an ARAM yesterday and noticed Shaco's boxes didnt proc 
or 
i went into a custom game with a friend to double check to make sure i didnt miss see it, and indeed neither item proc'd with the jack in the box skill, just confused if its supposed to work that way of if the skill isnt working properly.
I believe its not supposed to proc those. Same with heimer turrets I think. I think zyras plants proc them though, being that they arent an ability to be spammed with a single button.
Generally, summoned units that attack independently don't proc "on spell hit" passives. Zyra's an exception because her plants only live for a few seconds and are basically extensions of her other spells.
