Something that cannot be filled again after it is empty.
The nonrefillable bottle must be thrown away once it's empty.
Nonrefillable → It is formed from "non-" (meaning not) and "refillable" which is derived from "re-" (meaning again) and "fill" (from Old English "fyllan", meaning to make full). The word "nonrefillable" means not able to be filled again.
Think of something that cannot be filled again — 'non-' means not, 're-' means again, and 'fill' means to make full.
