The Philips AVENT Reusable Bottles, featuring the patented teat, do not come with sealing discs.
Philips AVENT bottles have been designed to be as natural as possible and also as practical as possible. The dome cap effectively seals the teat for leak-proof mixing, storage, and travel, a sealing disc is not needed. Sealing discs convert the Philips AVENT Natural Feeding bottles to milk and baby food storage jars.
