THERMOS FUNtainer Kids Food Jar 10oz Spider-Man — Vacuum-Insulated, Fold-Away Spoon

The THERMOS FUNtainer 10oz Spider-Man food jar is a small vacuum-insulated stainless steel lunch container with a fold-away spoon that keeps meals hot or cold for school or on-the-go.

Designed specifically for children, this compact Thermos pairs kid-friendly styling with reliable temperature retention. The 10-ounce stainless steel interior and vacuum insulation preserve warm soups or chilled snacks for hours, while the push-button lid and integrated utensil make lunchtime fuss-free. Lightweight and durable, it slips into most lunchboxes and resists everyday knocks and tumbles.

How long will the THERMOS FUNtainer keep food at a good temperature?

This jar uses double-wall vacuum insulation to maintain temperatures throughout the school day. Expect hot foods to stay warm for up to 5 hours and cold foods to remain cool for up to 7 hours under normal conditions. For best results, pre-warm or pre-chill the jar before filling.

• Hot retention: up to 5 hours with vacuum insulation technology
• Cold retention: up to 7 hours for chilled snacks and yogurt
• Tip: preheat or pre-chill with tap water for 5–10 minutes before use

What makes this jar easy for kids to use at school?

The FUNtainer was built with simple controls and a compact shape that children can manage independently. A push-button lid opens easily, and the integrated foldable spoon stores inside the lid so utensils aren’t forgotten at school. The wide mouth also makes scooping, filling and cleaning straightforward.

• Push-button lid for one-handed opening
• Foldable spoon stored inside the lid for convenience
• Wide-mouth opening for easy eating and cleaning

Is the jar durable and safe for everyday kid use?

Yes — the jar is constructed from 18/8 stainless steel to withstand bumps and drops common in school life. Its exterior resists sweating, so it stays comfortable to carry, and the product is BPA-free. While it is dishwasher-safe on the top rack, hand washing is recommended to protect graphics and seals.

• 18/8 stainless steel body for everyday durability
• Leak-proof when closed and sweat-proof exterior
• BPA-free materials; top-rack dishwasher-safe but hand wash advised
