I just recently started watching Gintama and am beginning to love it! I just
want to know if the joke is referring to another anime. Also, if there is any
reason at all on why it must be a vending machine.

I believe this is the first time he did it.

The reason this particular joke catches my interest is because it kept on
reoccurring. The second reason is because time travelling anime like
Steins;Gate is awesome. Even though it might not be the same.  
I just had to ask this question after the third time they used this joke on
the 10th episode, though it was not Gintoki and the alien character wants to
enter a car's boot/trunk.

question
gintama
What is this time machine gag referencing?


This running gag in the Gintama anime is actually from Doraemon. They are
referencing to how the entrance to a time machine is available at a hole
similar to a drawer, which is exactly where the time machine is in the
Doraemon anime. Here is list of the other parodies present in Gintama.
