The capless bottle design makes it easier to pour without removing a cap.
Capless → It is formed from "cap" (from Latin "caput", meaning head) and "-less" (meaning without). The word "capless" means without a cap or head covering.
Think of 'cap' as a head covering and '-less' meaning without — so capless means without a cap.
