Yumbox - what is it?


Yumbox is available in 2 designs (the Classic and the Panino).  It is designed to be nutritionally balanced, to help with portion control and to be leak-proof.  

Yumbox is the perfect tool to eat healthily whilst on the go; Yumbox fans are as little as weaning babies (who can have their purees packed next to their rice cakes), as active as busy school children (who can be encouraged to eat a nutritionally balanced diet by its educational, illustrated, tray) or as stylish as Ladies who Lunch (who love the easy, compact and stylish design for portion control and healthy eating).

These sorts of boxes (also known as Bento boxes) are very popular is the US and are becoming increasingly popular in the UK too.  Our Yumbox is a firm favourite in our household! Below you will can read about feature and faq of the Yumbox.




Leakproof Single Lid

Pack yoghurt next to crackers with no worries!  Yumbox's unique single lid seals all food wells individually.  Food won't touch or leak outside of the box. No need for plastic bags, cling-film or multiple lids (to lose!).  

The leak-proof lid is standard on both the Yumbox Classic design as well as the Yumbox Panino

Balance & Portion Control

Yumbox’s pre-portioned illustrated (and removable) tray guides you to pack a healthy and hassle-free lunch.  

The Classic Yumbox tray is divided into five ½ cup portions of the key food groups: Fruit, Vegetable, Grains, Protein, Dairy.  Plus a small well for a dip or a treat.  

The Panino Yumbox tray is divided into a large (2 cups) portion (perfect for a sandwich or salad), 2 (1/2 cup) portions and a dip well.

Think Green

Reuse, Reduce and Save! Yumbox saves you money by eliminating the need for plastic bags, multiple containers, clingfilm and snack packs. Pack a waste free lunch. All materials used in production are food safe, BPA-free and phthalates-free

Stylish yet Practical 

Pack your super stylish Yumbox for all meals on-the-go; school lunch, picnics, laptop lunches, travel and snacks   When you get home simply place the tray in the dishwasher, rinse out the outer box and you are ready for another adventure.  

Yumbox can also be packed the night before and the silisone lid will keep food fresh if kept in the fridge.

Child Friendly

Yumbox is sturdy and compact with an easy-open latch. It fits neatly into standard size thermal lunch bags.  

The Yumbox Classic (fully filled) offers a nutritionally balanced meal for a child between the ages of 3 and 10.  It is great for older children and adults for healthy snacks or for portion control.

For bigger appetites the Yumbox Panino offers all of the same great features but with a larger tray capacity and different layout.

Educational & Fun

The Classic Yumbox is a great way to teach your child about portion sizes and different food groups.   Offering a healthy variety of foods will instill good eating habits the fun way.

The Yumbox Panino is a fabulous tool to help control portion sizes (for kids and adults alike) whilst presenting food at its most appetising.  The portioned tray encourages you to pack variety and facilitates a healthier approach to food on the go.



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, follow these 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.

Is Yumbox dishwasher safe?

Yes, Yumbox is dishwasher safe. Top rack only. We highly recommend hand washing the outer shell and/or removing it before the heat dry cycle. Yumbox has been tested at temperature 65C/149F, 110 min. cycle. Yumbox is made with ABS (exterior box), Tritan (tray), and silicone (seal). Yumbox is designed with rounded edges and smooth surfaces to make hand washing easy.

Is Yumbox food safe?

Yes. All materials are food-safe, BPA-Free, Phthalates-free and are CPSIA and FDA compliant.

Is Yumbox microwavable?

We advise that everyone use their own judgement when deciding to microwave any plastics. If you own Yumbox with an acrylic tray (purchased before May 1, 2013), it is not microwaveable. If you purchased Yumbox after May 1, 2013, the Tritan tray only is microwave-safe.

Is Yumbox thermal?

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 tote with an ice pack to keep contents cool.

How big is Yumbox?

Yumbox is perfect for little kids! Its dimensions in a closed position are approximately 8.5 x 6.5 x 1.8 inches and weighs 1 lbs 1.5 oz.

Is Yumbox’s tray removable?

Yes. Yumbox’s tray fits snuggly in the bottom half of the exterior box. It can be removed easily for cleaning, packing or for at home use. In fact, kids love eating their meals out of Yumbox’s tray at home too! The first time you open Yumbox, you may find that the tray is slightly difficult to remove. After initial removal, it will return to its comfortably snug fit.

Is Yumbox’s lid removable?

This question applies to Yumboxes with a two-hinge design. We recommend NOT separating the lid from the base in order to avoid damaging the hinges. Yumbox is compact (even open) and fits in a dishwasher as is.

Can I pack a Yumbox lunch the night before and store it in the fridge?

Yes. Yumbox acts as an excellent storage container. The seal keeps foods fresh for days in the fridge.

What portions does Yumbox accommodate?

Yumbox now has two designs to make packing lunch for everyone easy! 
Yumbox's original 6-compartment food tray, is perfect for toddlers through age 8 who like variety. It accommodates five 1/2 cup portions of the five main food groups plus one dip/treat well. The illustrated trays reinforce healthy balanced meal packing. 
New Yumbox Panino 4-compartment food tray is sandwich-friendly. This is a great option for kids and adults of all ages that prefer sandwich and salad style lunches. It has one large sandwich size section with two smaller 1/2 cup sides plus a 1 oz dip/treat well.
