Questions & Answers about nodoame o kaban ni irete oku to, nodo ga itai toki ni tasukarimasu.
~ておく means to do something in advance or to do something and leave it that way for later convenience.
So かばんに入れておく means more than just put it in the bag. It means:
- put it in the bag ahead of time
- keep it in the bag so it will be there when needed
In this sentence, that nuance is important because the speaker means it is useful to keep throat lozenges in your bag in case your throat starts to hurt.
Because 入れる only means to put in.
- かばんに入れる = put it in the bag
- かばんに入れておく = put it in the bag beforehand / keep it in the bag for future use
The sentence is about preparation, not just the action of putting something somewhere. Using ~ておく shows that you are doing it with a future situation in mind.
