Trying to find a resealable bottle cap A long long time ago (.. I can still remember ♫) there were these old bottle caps. My parents still have 2 or 3 at home from soviet times. They look kinda like this:



What are those called? Ar there some keywords to find them? It took me at least 3- minutes to even find this image (and it was in  middle of completely unrelated images down on something like the third image-search page). Or, the best option, where can I buy a box of these?

P.S. I know that the image is from "flip-top" wikipedia page, but what I am looking for is a cap, that is independent from the bottle itself.
Found what I was looking for: WESTMARK 3 Flaschenverschlüsse, Flaschenstöpsel mit Hebel und Gummidichtung, 40 x 60 x 15 mm, farblich sortiert. 

 

Now I only need to order a box of these.
