Made as a plastic ring and cover, this cap resists rust and corrosion so it stays reliable with regular use. The tidy profile makes it easy to store with your feeding supplies.
Use the snap-on cap for newborn feedings and the hinging cover for toddlers who open their own cups. Works with Mason Bottle silicone straws, so it grows with everyday use.
The ring threads onto regular-mouth mason jars and seats outside the liquid, so contents never touch the cap. Snap it on after feeding to keep nipples and straws protected.
A few quick checks make sure this cap works for your bottles, routine, and childcare needs.
- Check Compatibility: This ring fits regular-mouth Mason jars, so confirm your jars are regular-mouth before ordering.
- Think About Age: Choose the hinging cap if toddlers will open it themselves, or use the simple snap for baby feedings.
- Cleaning Routine: Wash with warm, soapy water and air dry. Inspect regularly and replace if you see cracking or wear.
- Pack a Backup: Keep an extra ring and cap in your diaper bag or daycare supply to avoid last-minute stress.
- Travel and Daycare: Snap the cap on after feeding to protect nipples and straws, and label items for daycare to avoid mix-ups.
Will this fit my Mason Bottle cups and straws?
Yes, it fits all Mason Bottle drink tops and snaps secure over Mason Bottle silicone straws.
Does the cap touch the milk or formula inside?
No, the ring and cap sit outside the jar contents, so liquid does not contact them.
What is the ring and cap made from?
This is a plastic ring plus cap, designed to be durable and rust-resistant.
How should I clean the ring and cap?
Clean with warm, soapy water and air dry. If you prefer dishwashing or sterilizing, check Mason Bottle care guidance first.
