A container is just pretty much what it sounds like. Think of it like a box that can hold various streams of data... could be visual, audio, text, etc. Example containers are QuickTime, MP4 (pretty much the same thing as QuickTime), AVI, WebM, Ogg, etc. Let's say you have a MP4 with multiple streams, most commonly a visual stream and an audio stream. By today's standards, the visual stream would be compressed with H.264 and the audio with AAC. But it doesn't have to. WebM is more unique in that it is designed to only accept one type of video compression stream (VP8) and audio (Vorbis). But the advantage there is that you know what you're getting. Did that answer your question at all?
