FAQs about Kids Thermos

  • 1. Are thermos safe for kids?

    Yes, thermoses are safe for kids. As long as you heat the food properly before placing it in the lunchbox, there should be no issues with safety.

  • 2. How do I keep my lunch warm for school?

    A thermos is going to be your best option! To do so, you will need to boil some water and fill the thermos for ten minutes. Then, dump the water out and wipe the thermos clean. Pour your hot foods into the thermos and seal immediately. Viola! Food that stays warm for hours.

  • 3. Will a hot dog stay warm in a thermos?

    Sure! If your child enjoys hot dogs, I recommend sending them in a thermos. However, do not put the bun inside of the thermos with the heated hot dog. This is a recipe for a mushy nightmare. Instead, send the hot dog bun and condiments separately so your child can assemble them while they are at school.

  • 4. Can you put boiling water in a thermos flask?

    Yes, as long as it is made of stainless steel and not glass. (Don’t worry – all of the thermoses on this list are designed using stainless steel materials.) In fact, you are supposed to heat the thermos with boiling water before putting food inside.

  • 5. What can I put in my thermos for lunch?

    The possibilities are truly endless for what you can pack in your thermos for lunch. Some of the favorites in our household include: macaroni and cheese, fettuccine alfredo, soups of any kind, pizza rolls, chicken nuggets and fries, fish sticks, orange chicken and rice, and essentially any leftover.

    Keep in mind that the thermos is not limited to hot food. You can also send cold foods, too. We stick our thermos in the freezer the night before. Then, I will send things such as sushi, salad, yogurt parfaits, cold pasta salad, and other items that are better chilled.

  • 6. Will spaghetti stay hot in a thermos?

    Yes, spaghetti will stay hot in a thermos. Just use the boiling technique. Oh, and don’t forget to pack a salad and garlic bread on the side.

Conclusion

A thermos is a great way to expand your child’s lunch options. It is also great for sending hot or cold beverages to school. It’s important to find the thermos that’s right for you, though. A smaller child will likely need a smaller-sized thermos, as a larger one can be overwhelming at school, and they aren’t likely to finish it.

Are you ready to give your child the gift of hot meals at school?
