I know what bottle episode is:

A "bottle episode" is designed to take up as little money as possible. The easiest way to go about this is to use only the regular cast (or even just  part of the regular cast) and set it in a single location, especially if you have a main standing set. This keeps production costs down, because no one needs to scout locations, build new sets, or create fancy CGI graphics of the outside of the spaceship. Bottle episodes are often a chance for a slow, characterization-filled episode before/after a big special-effects-laden action episode. Of course, all this doesn't mean the episode  will be cheap, just that it's  meant to be; like any regular episode,  unforeseen complications can cause the show to run over the scheduled budget.
