Thank you for providing us with feedback on the design of our food jars. We greatly appreciate it. The lid of the jar features dimples to provide a better grip when opening. While we did not test it with gloves, we will forward your request to our research and development team for future consideration. To secure the lid in place, you need to place and twist it slightly. Once in place, the lid should stay in position.

We hope this helps! Let us know if you have any questions or concerns, we would love to help: https://www.zojirushi.com/app/customer_service/entry
