Baby bottle anatomy

A BABY BOTTLE is generally made up of four different pieces:

Bottle – Holds your milk or formula.

Nipple – A teat that your baby sucks liquid through.

Collar – Essentially a lid in the shape of a ring. The nipple sticks through the collar. The collar then screws onto the bottle and secures the nipple in place; preventing your baby from swallowing or choking on the nipple.

Travel Cover – Found on the majority (but not all) of baby bottles. The travel cover prevents dirt and grime coming into contact with the nipple when not in use.

Many different parts that make up a baby bottle :travel cap, collar, nipple and bottle.
