What to Consider When Buying a Locking Lunch Box

Locking lunchboxes have come a long way since the ubiquitous clangy metal ones of the 1990s that sported popular characters (He-man!) or TV shows (Alf!) and held a thermos, sandwich, apple and bag of chips bouncing around inside. 

Today there are so many options to choose from that sometimes it is difficult to know where to start and what to focus on in your quest. 

Whether you are looking for a leak-proof lunchbox for your own lunch or a durable one for your kids, there are several factors you’ll need to consider.


Compartments allow you to keep your food separate, so the number of items you want to keep separate will determine the number of compartments you are looking for. Having separate compartments will keep the different parts of your salad from becoming soggy before you have a chance to eat it, or keep your strawberries from ending up in your curry. 


Be sure to choose a design that fits your lifestyle and needs. Pay attention to whether a lunchbox has a handle. If it doesn’t you may need to purchase a separate carrying case or be prepared to throw it in a handbag or backpack. 


Focusing on a lunchbox’s leakproof abilities isn’t just for people with an affinity for soups. If you’re going to have, for instance, freshly washed raspberries in your lunchbox, you don’t want the juice that they expel to leak over onto your sandwich in another compartment. Be sure to choose a leakproof lunchbox if you plan to include any type of “wet” food (think: fruits, veggies, hummus) in your lunch. 


Keep in mind that the bulkier lunchboxes may be harder to toss into your bag as you head to work, so while you want a lunchbox that will hold enough food to stop your stomach from growling, it also needs to be easily portable. 


Is it going to last? Or will you be purchasing a new lunchbox again next month? You want to check the reviews to look for comments regarding the durability of a product. Choose a lunchbox that lasts a long time for the majority of purchasers. This will save you money in the long run, even if you pay a little more up front. 


“You get what you pay for” is the old adage that certainly rings true. While you don’t want to break the bank over purchasing a lunchbox, paying a fewer extra dollars will increase the likelihood that you are choosing a durable and long lasting product. 


Be sure to select a lunchbox that will be large enough to hold the type of lunch you want to carry. A thin material, like steel for instance, will allow a lunchbox to hold more food than a lunchbox of the same size made of thick, hard plastic. Check for amount of food that the lunchbox will hold. 


Insulation maintains a safe temperature for your food, particularly if you are unable to keep it in a fridge. You want a lunchbox that will keep your hot food hot or your cold food cold.
