This could refer to the door-mounted kitchen bins, where the lid swings open when you open the door. "Svingbar avfallsbeholder. Når døren åpnes, løftes lokket." See picture. "svingbar søppelbøtte" or "søppelbøtte med svingbart lokk" are other suggestions. Usually the type Bjørnar refers to ("vippbart lokk") is called "swing-top lid", but this is by no means the rule. Hopefully you have more details to help you decide which alternative is relevant to your context.
