Yumbox

Yumbox is a kid-friendly, bento-style lunch container designed to help parents pack healthy lunches. Yumbox is made with high quality, super durable, BPA-free, food-safe materials. Read on to learn more or contact us with questions.


Is Yumbox leakproof?

Yes. Yumbox is a leakproof container. Yumbox’s silicone lid engages with the tray to create a tight seal keeping food contents in place, including wet foods like yogurt and applesauce (not water). Foods will not leak between compartments or outside of the box.

How do I pack wet foods?

Yumbox is designed to hold wet foods but not liquids. To ensure that food stays in place and does not leak to other compartments, be sure to follow 4 Easy Steps: 1) Do not overfill compartments (an overfilled compartment could cause another to leak as well); 2) Remove any excess liquid from canned fruit, applesauce and yogurts; 3) Keep contents cool by adding an ice pack to your lunch tote; 4) When closing Yumbox, press down on the lid with the palm of your hand and snap latch to closed position to create the best seal. Do not pack yogurt drinks, soups or runny/watery dressings. Do pack foods with the consistency of ranch dressing, ketchup, chunky salsas, hummus, yogurt, and veggie dips. These are all great options. Some oily vinaigrettes may leak out of the dip well. One trick that can help keep vinaigrettes in place is to dress the salad and top it with a few croutons. The croutons will absorb excess oil/liquid and keep the vinaigrette from seeping into a neighboring compartment. If you are not sure if your food choice is too liquidy to pack, we suggest that you conduct a quick test before sending your child to school with that food. Simply add the test food to a compartment, close Yumbox properly and give it a good shake (or leave it on its side for 10 min.). Set Yumbox back to normal position and open to see the results.

The five main food wells can accommodate ½ cup servings. Yumbox was designed to assist parents in presenting a healthy meal with a variety of foods to create a balanced meal. You may use less food for a toddler or fill each well for an older child.

In our testing, we found that meals served in Yumbox will satisfy kids up to 10 years of age or be a great snack for older kids. Some children may be hungrier depending on their daily activities.

Yumbox cannot control the amount of sugar, salt, calories or fat that you add to the foods you serve. Make healthy choices by selecting fresh foods, using good oils like olive oil, reducing sodium and sugar as much as possible. Yumbox is not intended to be used as a replacement for professional advice. Each child is unique with different dietary challenges. Please consult a doctor if you have concerns about your child’s diet.
