Spixal Insulated Food Jar vs Montii Food Jar vs Thermos Food Container: What's The Difference?
If you're shopping for an insulated food jar, chances are you've come across three popular options:
- Spixal Large Insulated Food Jar
- Montii Food Jar
- Thermos Food Container
At first glance they might seem similar. They all keep food warm, they're all designed for lunches, and they're all made to be portable.
But once you start comparing capacity, practicality and who they're designed for, some important differences become clear.
As a mum who packs school lunches and work lunches nearly every day, I've learned that the biggest factor isn't usually insulation.
It's whether the food jar actually holds enough food.
If you're looking for a food jar designed for full lunches rather than smaller portions, explore the Large Insulated Food Jar Collection. With a generous 800ml capacity, Spixal food jars are designed for growing kids, teenagers and adults who need a genuine meal-sized solution.
The jars also fit upright inside the Work Lunch Bags collection and coordinate with matching Kids Backpacks.

The Biggest Difference: Capacity
When comparing insulated food jars, capacity is often the most important difference.
Many food jars on the market sit within the 200ml–500ml range.
Those sizes work well for:
- Snacks
- Smaller meals
- Younger children
- Side dishes
But many families eventually discover they're not large enough for older children, teenagers or adults.
The Spixal Large Insulated Food Jar was designed specifically to solve this problem.
With a generous 800ml capacity, it offers substantially more room for full lunches and larger portions.
What Does 800ml Actually Mean?
The numbers don't always mean much until you start packing food.
An 800ml food jar comfortably fits meals such as:
- Large serves of pasta
- Butter chicken and rice
- Chicken fried rice
- Noodle dishes
- Lasagne
- Soup
- Curries
- Leftovers
- Up to 12 chicken nuggets
For teenagers and adults, that extra capacity can make a significant difference.
Which Food Jar Is Best For Teenagers?
This is where capacity becomes especially important.
Teenagers often outgrow smaller food jars very quickly.
As appetites increase, many parents find themselves needing a container capable of holding a genuine meal rather than a snack-sized portion.
The Spixal Large Food Jar was designed specifically with larger lunches in mind.
That makes it particularly suited to:
- Teenagers
- High school students
- University students
- Working adults
- Tradies
- Commuters
Material Quality Matters Too
Capacity isn't the only thing worth considering.
Food safety and durability are equally important.
The Spixal Large Food Jar uses:
- 304 stainless steel
- BPA-free materials
- FDA-tested materials
304 stainless steel is widely regarded as one of the best materials for food containers because it is:
- Food safe
- Durable
- Odour resistant
- Easy to clean
- Corrosion resistant
Which Food Jar Is Best For School Lunches?
The answer depends largely on your child's age and appetite.
For younger children, smaller capacities may be perfectly suitable.
For growing children and teenagers, larger capacities provide greater flexibility and often allow parents to pack more substantial meals.
The ability to pack a full serve of pasta, fried rice or leftovers without running out of space can make lunch preparation much easier.
Which Food Jar Is Best For Adults?
Many insulated food jars are designed primarily with children in mind.
The challenge is that adult lunches are often larger.
The 800ml capacity of the Spixal Large Food Jar makes it equally suitable for:
- Office workers
- Commuters
- Teachers
- Nurses
- Tradies
- University students
It also fits neatly upright inside the Work Lunch Bags collection.
Dishwasher Safe Convenience
When you're using a food jar every day, cleaning matters.
Busy families often prefer products that can go straight into the dishwasher.
The Spixal Large Food Jar is dishwasher safe, helping reduce cleanup time and simplify everyday lunch routines.
Designed To Coordinate With Your Lunch System
One feature that makes Spixal different is its broader lunch and carry ecosystem.
The Large Food Jar has been designed to coordinate with:
- Kids Backpacks
- Lunch Bags
- Bento Boxes
- Lunch Accessories
The dual-tone colours feature complementary clips and branding details that create a coordinated look across the wider range.
For families who value organisation and matching lunch gear, this can be a meaningful advantage.
Who Should Choose The Spixal Large Food Jar?
The Spixal Large Food Jar is particularly suited to:
- Parents of teenagers
- Families wanting larger portions
- People who pack leftovers regularly
- Adults taking lunches to work
- Anyone frustrated by smaller food jars
If you've ever finished packing lunch and thought, "I wish this container was bigger," you're probably the ideal customer.
