Should be CupWOW

9/6/2018 by AJ

In working in an environment where I'm required to have a lid on my drink, this is the best thing I've run into so far. My job is busy and I talk most of the time. So I needed something that held a lot of water or juice and can be taken on the go. When you turn the jar slightly to the side there's no leakage which is what I was looking for.
Co-workers are jealous, and my neighbor asked for one to try out. Hats off you guys!

Cuppow | To-Go Lid for Mason Jars

About Cuppow

Raise A Glass

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.
