Your BP should be left alone not handling no rooming around until he eats successfully for you, I know it is hard but it is important.
When you talk about plastic box is that where you house him or feed him?
If this is where you house him keep it this way, it is very important to provide maximum security especially with young BP.
Now if you use this to feed him I would suggest that you feed him in his enclosure to avoid the stress caused by handling him prior to eat.
And again make sure you husbandry is optimal proper temps, humidity tight enclosure tight hides etc
