FUNtainer Water Bottle vs Food Jar: Which Does Your Kid Need?

Category: Comparisons
A 12oz FUNtainer water bottle keeps drinks cold for up to 12 hours, while a 10oz food jar holds hot food for up to 5 hours. Here's how to decide which one your child actually needs for school.
Quick answer
Buy the 12oz FUNtainer water bottle if your child mainly needs cold drinks through the school day. Buy the 10oz FUNtainer food jar if they bring soup, pasta, or yogurt and need it to stay at the right temperature until lunch. If you can only get one, match it to whichever problem you actually have: hydration or hot food.
What each container is actually built to do
The 12oz FUNtainer water bottle is a vacuum-insulated stainless steel bottle that keeps drinks cold for up to 12 hours, with no ice needed. Its push-button lid covers a silicone straw when not in use, and an integrated soft-touch carry handle makes it easy for kids to tote. The 10oz FUNtainer food jar is a different tool: a stainless steel insulated jar that keeps hot food hot for up to 5 hours and cold food cold for up to 7 hours, with a wide-mouth opening that fits a kids' spoon. One is for drinking; the other is for eating. That single difference drives every other choice you'll make.
Capacity and what fits inside
The 12oz bottle holds a standard kid-sized drink portion and fits alongside lunch items in a Thermos kids lunch box. The 10oz food jar holds a single serving of soup, pasta, yogurt, or snacks — enough for one lunch, not a shareable portion. If your child eats a large lunch or you're packing for two, one 10oz jar may run short. If your child mostly drinks water and eats a school-provided meal, the bottle alone covers the need.
Cleaning, durability, and daily handling
Both the 12oz water bottle and the 10oz food jar are dishwasher safe on the top rack only, and both use BPA-free materials. The bottle's double-wall stainless steel construction handles drops, dings, and roughhousing. The food jar is also stainless steel and built for daily transport. One practical difference: the Paw Patrol 10oz food jar includes a spoon, while the Batman 10oz food jar does not. If your child needs a spoon at school, that inclusion matters more than the character on the outside.
How to choose when you're buying both
If you're building a full lunch kit, the Pokémon Bundle pairs a novelty lunch box with a 12oz FUNtainer water bottle and a 10oz FUNtainer food jar, so you get both containers plus a bag sized to fit them. That bundle is the simplest path if you want a matched set and don't want to compare capacities separately. If you already own a lunch box, buying the bottle and jar individually lets you pick the exact character and size your child will actually use.
Trade-offs at a glance
- Bottle-only simplicity: The 12oz water bottle handles cold drinks for up to 12 hours and nothing else. It won't keep soup warm or hold yogurt at a safe temperature. Choose this if your child buys or brings a separate lunch and just needs a reliable drink.
- Food jar versatility: The 10oz food jar keeps hot food hot for up to 5 hours and cold food cold for up to 7 hours, but it doesn't replace a water bottle for all-day sipping. Choose this if hot or temperature-sensitive food is the main problem you're solving.
- Bundle vs. individual: The Pokémon Bundle gives you both containers plus a lunch box sized to fit them. Buying individually lets you choose a specific character and skip the lunch box if you already have one. Start with the bundle if you're outfitting a lunch kit from scratch; go individual if you're replacing one piece.

Which one fits your kid
Best for
- Kids who need cold water available all day and eat a school-provided or separate lunch
- Families replacing a single lost or worn-out container rather than starting a full lunch kit
- Parents who want a food jar with a spoon already included (Paw Patrol 10oz)
Not for
- Kids who need hot soup or pasta at lunch — that requires the food jar, not the bottle
- Families who want one container to do both jobs; no single FUNtainer replaces the other
- Kids who need a spoon at school and choose the Batman 10oz jar, which does not include one
