Hot or Cold? Have your Meals Exactly How you Like!

As much as we enjoy take-aways and eating at food joints when working, nothing beats the freshness and goodness of some nice homemade meals. And it’s quite easy to bring your meals to work, outdoor escapades, or pack them for the children when going to school.

What you need by your side is a lunch box or a food flask. With food flasks, you can embrace a healthy culture of eating homemade meals wherever you are. It will also save you money and waiting for all those people at food joints.

Why give Food Flasks a Chance?

Do you remember how hectic it is to queue for the office microwave during lunch breaks? Or when you leave your food in the fridge to keep it cool and someone in the office gets away with it? You can bid these misadventures goodbye if you have a food flask.

Food flasks are good at retaining insulation, meaning your food will stay hot or cold as you served it. You do not need a microwave to warm it or a fridge to keep it cool. Secondly, food flasks have a wide mouth as well as wide and deep lids that double as serving bowls. You can enjoy your meals directly from your flask.

What Should You Look for When Buying a Food Flask?

With the many food flask choices in the market, we know how difficult it can get when shopping for one. The ultimate goal is to buy a food flask that preserves the freshness and the taste of your homemade meals. But that does not mean choosing the perfect food flask will be any easier. What should you look for from your perfect food flask?

First, what type of food do you wish to carry? Solid or liquid form? The design of the flask needs to be leak-proof, otherwise, you will end up with a leaking flask that destroys your bag and other contents. A leak-proof flask allows you to carry liquid foods like soup and meals with stew and never have to worry about any leaks.

You should also look for a food flask whose lid doubles as a serving bowl. It makes it easy for you to eat your meals from anywhere and saves you the hassle of carrying a separate bowl or looking for a plate whenever you are. Flasks with such lids will have a wide and deep design to fit enough food.

Also, consider other accessories. Who does not like products that come with extra accessories, which make your usage of the product better? Some of the accessories to consider when buying a food flask include a spoon, cleaning sponge and a carrying bag. Once you know what to look for, as well as the best features to consider, buying a food flask will get less overwhelming.

Always Think About...

  • The material of the food flask, which determines its durability and insulation capabilities. Some food flasks are made from plastic while others have a metallic material. The most common metallic material used in food flasks is stainless steel, which is the best for retaining insulation. With a plastic food flask, your meals will lose their heat or coolness.
  • Heat retention, depending on how long after packing your meals you will need to consume them. The longer the heat retention time the better, whether you are packing cold or hot food. It’s advisable to preheat the flasks with hot water to enhance its insulation. Also, most flasks will retain the heat as described by the manufacturer, but you’ll need to fill the flask fully.
  • Capacity, depending on who is using the flask and what foods you need to carry. Food flask capacities range from 300mls to 700mls. Some can go past these sizes, but if you know what you need the flask for, it will be easy to choose the right size and capacity. 
  • Cost, depending on what your budget is. You do not have to spend a lot of money to buy a food flask. Some have high price tags but you can get affordable ones with similar features. What you can do is go through our reviews to see whether the product is reliable and meets your budget requirements.

The perfect food flask is somewhere out there and is waiting for you to get it. Forget about tasteless meals from cafeterias and vending machines that won't give you what you want.
