Describing something that does not have a container or is not enclosed in a container.
The containerless design of the packaging makes it more environmentally friendly.
Containerless → It is formed from "container" (from the Latin "continere", meaning to hold together) and "-less" (meaning without). The word "containerless" means without a container or not having a container.
Think of something that is 'without' ('-less') a 'holder' ('container') — that's why containerless means lacking a container.
