Mason jars make great drinking glasses. They’re inexpensive, durable, heat-resistant, and recyclable, plus they’ve got a casual, nostalgic vibe that adds to the appeal. But the spill factor makes it tough to use a Mason jar on the go. After a few too many spills in the car, Joshua Resnikoff starting thinking there must be a way to make a Mason jar more travel friendly. He teamed with his friend Aaron Panone, a mechanical engineer, and together they created Cuppow, a BPA-free plastic lid that turns an ordinary Mason jar into a travel mug. Cuppow is designed for both large and regular mouth Mason or canning jars. The dishwasher-safe lid fits underneath the screw-on ring that comes with a canning jar. Cuppow does all its design, development, packaging, and manufacturing in Massachusetts, where Joshua and Aaron tapped a team of fellow entrepreneurs at Fringe, a business incubator and coworking space in Somerville. It’s a community effort, with universal drinking appeal.
