Thermos FUNtainer 12 oz Straw Bottle
A durable insulated straw bottle for young kids that needs regular straw cleaning.
We bought Tommee Tippee Insulated Straw Toddler Tumbler Cup ~ 12+ months, 2 Count. It's no longer documented anywhere, so this page reviews the closest well-covered match. It is a widely reviewed insulated straw cup for toddlers and young kids with a readable maker page, doing the same job as the Tommee Tippee tumbler.
The short version
- Toddlers and preschoolers moving to an independent straw bottle
- Daycare, school lunch and car trips where cold drinks matter
- Families who want one bottle that takes rough handling
- You want a cup for warm milk or other warm drinks
- You will not clean a straw and valve by hand most days
- You need a cup that stays sealed while a child walks around with it open
What owners like
- Drinks stay cold through a full school or daycare day
- The outside stays dry, so no condensation in lunch bags
- Survives repeated drops with only cosmetic marks
- Easy for young kids to open and drink from on their own
Common complaints
- The silicone straw and valve need frequent hand scrubbing with small brushes to avoid buildup
- Water runs out of the air vent if the bottle tips over while the lid is open
- Printed graphics can chip or wear with dishwasher use
- Not for warm or hot drinks

What it does
A 12 ounce vacuum insulated stainless steel kids bottle with a push button lid and pop up silicone straw. This page covers it in place of the Tommee Tippee insulated straw tumbler, which had too little readable coverage.
- Keeps drinks cold for hours without ice
- Straw stays covered when the lid is closed
- Push button a small child can work alone
- Steel body that handles drops and dings
- Replacement straws are sold separately
A good pick for toddlers and young kids who need cold drinks at daycare, school or in the car, since reviewers report long cold retention and a body that survives drops. The trade-off is upkeep: the straw and lid need regular hand cleaning, and the vent lets water out if an open bottle tips over.
