The Verdict
This 16-ounce stainless steel food jar earns an 8.1 performance score by keeping meals contained and holding their temperature well. Its vacuum insulation suits soup, oatmeal, and pasta for school or work, while the dishwasher-safe build simplifies cleanup. The narrow capacity limits it to a modest meal, and you must heat food before filling it because the jar cannot go in a microwave.
Who it's for: Choose it if you want one warm meal in a compact, leakproof jar and can accept the 16-ounce limit.
Who should skip it: Skip it if you need a larger lunch or want to reheat food inside the container, since its 16-ounce capacity is modest and it is not microwave safe.
In-Depth Review
Performance
Performance earns 8.1/10, with the clear strength being Holds temps reliably. The 16 oz THERMOS FUNTAINER uses vacuum insulation and an 18/8 stainless steel body. That pairing suits soup, pasta, oatmeal, and similar meals that need to stay warm until lunch.
The leakproof rating is Yes when the lid is closed. That matters in a school or work bag, where a loose seal can ruin other items. Still, temperature results depend on how hot the food is at filling and how often the lid opens. The 16 oz capacity also limits how much food you can carry. It works best as one compact meal, not a full-day food container.
Build Quality
Build quality also scores 8.1/10, matching Tight seals, sturdy feel. The 18/8 stainless steel construction should handle regular packing better than a thin plastic jar. The 6.7 x 3.7 x 3.5 inch body has a compact shape, yet it leaves enough room for a single serving.
The vacuum construction adds insulation without relying on a bulky outer shell. The leakproof design also suggests a close-fitting lid and seal, though seals still need regular cleaning to prevent food residue from affecting closure. Dishwasher-safe construction helps with that task, but THERMOS recommends hand washing. That advice may help preserve the lid and sealing parts over time.
Usability
Usability receives 8.1/10 for a Simple packing flow. The jar has one 16 oz interior rather than a multi-part lunch layout, so packing stays direct. Fill it with a prepared meal, close the lid, and place it upright in a bag. Its 6.7-inch height also makes the jar easy to identify and handle.
Cleanup is more convenient because the container is dishwasher safe. The stainless steel interior should also resist lingering food odors better than some plastic containers. There is one important limit: the jar is not microwave safe. You must heat food separately, then transfer it before leaving home. That extra step reduces convenience for meals that need reheating at lunch.
Portability
Portability scores 7.7/10, which fits Carries comfortably, stays secure. At 6.7 x 3.7 x 3.5 inches, the jar takes less space than a wide lunch box and fits neatly into many bags. Its upright shape also helps keep the 16 oz meal contained without spreading across the bag.
The narrow footprint is useful for children and adults who carry several items. However, the jar still adds more height than a flat container. The 16 oz capacity keeps the overall format manageable, but the same limit may require a second container for fruit, snacks, or a larger meal. It travels best when used as the main dish in a separate lunch setup.
Value
Value earns 8.2/10 and reaches Features worth the price. The combination of vacuum insulation, a leakproof seal, dishwasher-safe construction, and an 18/8 stainless steel body covers the needs of a daily hot-food jar. The 16 oz capacity also keeps the product focused and easy to carry.
Its value depends on whether that capacity matches your routine. Smaller meals gain a durable, temperature-retaining container in a 6.7 x 3.7 x 3.5 inch form. Larger appetites may find the jar too small and need another food container. The lack of microwave safety adds a second trade-off, since meals must be heated before filling. For one warm meal without plastic, the design stays practical and well balanced.
Frequently Asked Questions
How much food fits in the THERMOS FUNTAINER 16 oz Food Jar?
The jar holds 16 ounces of food, which suits a small meal, soup serving, oatmeal, pasta, or snacks. Its capacity may feel limited for larger appetites or a full meal with several separate foods.
What are the dimensions of the THERMOS FUNTAINER 16 oz Food Jar?
It measures 6.7 by 3.7 by 3.5 inches. The tall, compact shape fits many lunch bags, but check your bag’s height and opening before buying.
Does the THERMOS FUNTAINER 16 oz Food Jar keep food hot or cold?

Can I microwave or put the THERMOS FUNTAINER 16 oz Food Jar in the dishwasher?
Do not microwave this food jar because it is not microwave safe. You can place it in the dishwasher, which makes routine cleanup easier, but follow the care instructions for the lid and sealing parts.
Is the THERMOS FUNTAINER 16 oz Food Jar a good choice for a child’s lunch?
It works well for a child who needs one warm or cold food in a compact container. The stainless steel body and leakproof seal support daily transport, but the 16 ounce capacity may be too small for older children or larger meals. Since it has no separate sections, pack other foods in additional containers.
Final Verdict
This is a recommended buy for children or adults who need a sturdy jar for one warm meal or snack. It holds temperatures reliably, seals tightly, and can go in the dishwasher. The main tradeoff is its small 16 ounce capacity, which may not satisfy bigger appetites. It also cannot go in the microwave, so food must be heated before packing.
Choose it if dependable insulation and spill control matter more than carrying a large meal or reheating food in the container. If that matches your daily routine, this is a sound pick.
