Product Details

U-Konserve’s stainless steel leak-proof insulated food jar 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.

Similar to a thermos, this jar keeps 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. Keeps pre-heated food hot up to 5 hours, and pre-chilled food cold at least 8 hours.

  • Plastic-free, stainless steel interior
  • Double-walled and vacuum insulated
  • Leak-proof and airtight
  • Exterior stays room temperature and condensation-free 
  • Free of BPA, phthalates and lead

About U-Konserve
Kids Konserve waste-free lunch kits and U-Konserve reusable lunch-packing products were a natural outgrowth of what two women saw as a critical need that required immediate attention. With the premise that any business they undertook had to help the environment in some way, it didn’t take much imagination to see how they, as parents of young children, were contributing to garbage landfills, pollutants and sending the wrong message to their own children. How could they set an example of conservation for their children and empower them to be examples of change for the future? Calculating the amount of lunch trash being produced each day at their own schools shocked them enough to begin more research into reusable products that would dramatically cut down on our Earth’s ever-growing garbage pile. Focusing on how school lunch programs operate opened their eyes and propelled them to create Kids Konserve & U-Konserve.
