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 ketchup and applesauce (not water / juice / soup etc). Foods will not leak between compartments or outside of the box.
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; 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 neighbouring 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. If you conduct this test with regular yoghurt and the box leaks please contact us to arrange for the box to be tested for any (extremely rare) manufacturing fault.
Yumbox is compact and fits neatly in standard size thermal lunch bags available in most supermarkets and department stores. Please visit us on Pinterest for lunch bag ideas.
Yes. All materials are food-safe, BPA-Free, Phthalates-free and are CPSIA and FDA compliant.
We advise that everyone use their own judgement when deciding to microwave any plastics. Only the Tritan tray is microwave-safe.
No. Yumbox is not made with thermal materials. If adding food like yogurt, which should be kept cold, we recommend packing Yumbox in a thermal lunch bag with an ice pack to keep contents cool.
Yes. Yumbox is dishwasher safe. Yumbox was tested at temperatures of 65C/149F. As dishwasher temps vary, we recommend using the top rack only. While Yumbox is dishwasher safe, hand washing the outer box is recommended to preserve the seal. Yumbox is designed with rounded edges and smooth surfaces to make hand cleaning easy.Yumbox is made with ABS (exterior box), Tritan (tray), and silicone (seal).
Yumbox is not sold with accessories at this time. However, we will be offering accompanying products in the future. Please visit us on Pinterest for accessory ideas.
You are unable to interchange trays between the Classic Yumboxes and between the Panino as the silicone lining on the lid changes between each one and the seal will not fit (meaning the Yumbox will not be leakproof). The Yumbox Tapas is designed specifically to have an interchangeable tray.
Over time the silicone may absorb oils from your food. This can create funny smells and / or a shiny film. You can re,move this by scouring lightly with some bicarb or soda or baking powder.
Yes. Yumbox acts as an excellent storage container. The seal keeps foods fresh for days in the fridge.
Our recommendation is to place the Yumbox trays in the dishwasher / on the draining board with the compartments facing upwards. This does mean that water will collect in them but this is easy to remove with a tea towel. What this enables is for the underside of the tray (which is harder to wipe out) to drip dry.
Mould will form on the silicone if the box is stored closed without being fully dried. This is considered to be a usage fault and we will not replace boxes where this has happened. To prevent this always store Yumboxes open where possible, or closed only when they are fully dry. If your box has developed mould this can be removed by soaking in vinegar / bi carb of soda or milton sterilising tablets.
