U konserve food jar

Our stainless steel leak-proof insulated thermos with an all-stainless interior keeps food hot or cold for hours! Pack soup or chili in the morning and lunch will be steaming when you are ready to eat. Pack smoothies or yogurt and it stays cool until lunchtime. Take leftovers on-the-go so you can eat healthier and reduce food waste with our double-walled food jars. Similar to a thermos, they keep the temperature you start with, so pre-heat with very hot water for a few minutes before adding piping hot food, and pre-chill in the freezer for a few minutes (lid off) before adding cold food. U-Konserve insulated food jars keep pre-heated food hot up to 5 hours, and pre-chilled food cold at least 8 hours.
 
What started as a resource for school children quickly became a full line of zero-waste food-storage essentials for the whole family to use at home and on the go. After more than a decade of growth and transition, the same goals still guide the company today. As a Certified B Corporation, the company is using business for good by creating a positive impact for employees, communities and the environment. The initial mission to protect the planet has grown into a lifestyle of reusing more, wasting less, and raising awareness about the exciting and growing movement to reduce single-use plastic. U-Konserve merged last year with EcoVessel and gives 1% for the Planet for all its proceeds.
