Benefits of the Thermos FUNtainer Water Bottle

Easy to carry

The stainless-steel material is light-weight making it easy for a kid to carry. Similarly, FUNtainers are specifically designed to fit in small hands. Their slim design makes them best for kids aged 10 and below.

Stylish design

The bottles come in different stylish designs giving you a variety to choose from. They are uniquely designed to be fun for kids by mimicking cartoon characters, superheros, or outdoor scenery.

The variety of stickers including inspirational quotes and seasonal decorations gives a chance for kids to turn their bottles into their own ‘work of art’, which is encourages creativity. Your kid will learn, have fun and stay hydrated.

The bottle is fitted with a button-release cap that stops dirt from getting in and around the mouthpiece and keeps the straw clean.

Easy to use

The lid is well-designed to make it easy for kids to open and close on their own. They are ideal for kids as young as 14 months. Additionally, the exterior is sweat-free making it easy to grab and hold on to.

Leak Proof

The in-built straw in the 12 oz bottles and a click-shut lid design (for both 12 oz and 16 oz bottles) is significant for preventing leaks.

Also, the click-shut lid is easy to open (and close), unlike many other water bottles with a supposed “leakproof design.”

However, the bottle may, of course, leak if your kid forgets to click-shut the lid.

Main Features of the FUNtainer Water Bottle

Double-walled stainless steel

The bottle is made of a BPA-free non-toxic stainless steel that is insulated to keep the water cold for up to 12 hours. Therefore, your kid can enjoy a cold refreshing beverage throughout the day.

During after-hours school activities, the FUNtainer bottle provides your kid with the satisfaction of a cold fresh drink to “quench the thirst.” Refreshing indeed!

Straw design

The straw is curved in the 12 oz water bottles, but water is still allowed to flow freely. The curved straw design makes it easier to drink while keeping the bottle vertical – PERFECT for car or stroller trips!

The straw also separates into two-part, which can both be removed making it ideal for easy cleaning. This detachable straw system is more hygenic than many other kids bottle designs.

Lid design

The lid prevents spills and stops your kid’s grubby fingers from playing with the straw when not being used. There is also a small flip up handle attached to the lid that makes it easy to carry around. The handle is easily attached to a backpack or lunch box.

What’s the difference between Thermos Foogo and FUNtainer?

Although both the Thermos Foogo and FUNtainer are durable water bottles for kids, they have notable differences.

First, Foogo is specifically designed for very young kids.

For example, it has a rubber lid and base that is easier to use by younger children than the FUNtainer.

The other distinction is that FUNtainer offers over 30 different designs while Foogo is limited to just two designs.

Lastly, Foogo is cheaper compared to FUNtainer.

Pro’s and Cons of the Thermos FUNtainer Water Bottle


Affordability – FUNtainer water bottles offer competitive prices compared to other brands. For just $11.99, your kids can enjoy cool designs that appeal to them and go in line with their favorite cartoon, superheroes, or role models.

Environmentally-friendly – environmental protection is a critical concern today. Using products that help achieve this goal is essential.

Thermos FUNtainer ensures this by using durable stainless material to prevent plastic pollution.

Hygenic – FUNtainer uses non-toxic materials. Also, their design prevents dirt from reaching the straw when the bottle is dropped.

The mouthpiece is germ-free, thanks to the pop-up straw design.

Easy maintenance – a removable lid and a two-part straw that is easy to disassemble makes cleaning and maintenance a breeze.

Better yet, the straw is replaceable; when you notice that it’s wearing out, don’t worry about purchasing a new water bottle. All you need is a replacement straw, and you are good to go.


Leaks when not click-shut – if your kid forgets to close the lid properly, the bottle will leak.

Reviews – some customers raise concerns about the durability of some versions of the FUNtainer bottles. They complain about some bottles not even lasting a month due to poor quality.


How do you Clean Thermos FUNtainer Bottles?

Clean the water bottle before first use and soon after each use. Here is how it’s done:

  • Remove the lid and disassemble the two parts of the straw.
  • Prepare warm soapy water. Use some of it to fill the bottle and clean the other parts thoroughly in the water.
  • Use a soft cleaning brush to thoroughly clean the bottle.
  • Properly rinse all the parts in clean warm soapy water.
  • Leave them to completely dry before assembly.


  • You should not leave any liquid contents in the bottle for more than 24 hours.
  • Avoid using abrasive cleaners /scrubbers as they may damage the bottle’s finish.
  • Also avoid use of bleach or chlorine based cleaners

Can I wash my Kid’s FUNtainer Bottle in the Dishwasher?

Yes, you can since FUNtainer is top-rank dishwasher friendly. However, hand wash is recommended to ensure that all parts are thoroughly cleaned.

Also, using the dishwasher may affect the bottle’s appearance due to detergents and food residue in the dishwasher.

Can I put warm water in the FUNtainer Water Bottle?

Unfortunately, the FUNtainer kids’ water bottles are designed for cold drinks only. They have been insulated to ensure that cold water retains that temperature for up to 12 hours.

However, it’s essential to note that you pre-chill the bottle before use. To do this, fill it with cold tap water, cover it, leave it for about 5-10 minutes, then empty the content. Refill the bottle again with cold water and attach the lid to improve thermal efficiency.

Can I place the FUNtainer Water Bottle in the Freezer?

It would be best if you didn’t place a stainless steel water bottle in the freezer. This is because freezing liquid in the bottle expands, forcing pressure on the bottle, which can cause it to break.

Bottom Line

Thermos FUNtainer kids’ water bottles are not just easy to use but also fun and appealing. The slick design of the FUNtainer water bottle and how they incorporate kids’ characters is a great way to encourage children to drink more water in a fun and appealing way.

Always remind your kids to correctly close the lid and avoid chewing the straw to avoid leakage.

Hopefully, this review gives you a comprehensive insight into one of the best water bottles for your child.
