In Japan the most of vending machines are produced by the bottling service firm, like Coca Cola, to be suited for every single bottle sizes. Of course they manufacture them in their related firms.

You can google “自動販売機 製造” (means “vending machines manufacture”), and Sanden is a popular firm in the searched, even so, most of them are modest and medium-sized enterprises.
