Cuppow

To-Go Lids for Mason Jars

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.

    Hi Daily Grommet. A canning jar already makes an ideal drinking and travel cup; it's easy to wash, durable, inexpensive, and can be sealed. It, however, isn't a great solution for drinking on the move and so I took my idea for a drinking lid to my friend Aaron and the Cuppow! was born. I'm here to answer your questions.

    What a well timed Grommet for me! When I use my juicer, I use mason jars - they're the only things that fit well. Just this morning I was lamenting the terrible drinking experience. Can't wait to try these lids!

    @Catherine that's great! Just an FYI - your blender probably uses regular mouth mason jars. Cuppow was designed specifically to fit onto wide mouth mason jars! But have no fear because we are prototyping a version for people just like you that should be out before the summer! Thanks!

    Hi Joshua and Katherine and everyone else! Great video as always, I miss you all! I was waiting to see when these would be featured, they have Grommet written all over them. They certainly have the DanFranChap stamp of approval, I could make a list of 983465928 awesome things about them. Props to Joshua, Aaron and the team at Fringe!

    I'm on a "zero-waste" kick lately, trying to minimize the amount of stuff I throw out. I'm no where near zero, but containers like mason jars are really helpful. They're so versatile, and the Cuppow makes it even more so.

    Much love all around,

    Two questions:

    1) Are these sold in retail stores (where?)

    2) This is a little off topic, but I've heard you can use a wide-mouth Mason Jar on a blender. Is that true? Are there any instructional videos online to show me how to do that. Are there any online recipes? (I could probably Google all that, but figured you folks might have the best info). Thanks, Jim

  • Katie

    4/20/12 6:37 AM

    @Jim- Yes you can use a mason jar on a blender, depends on the type of blender if you use a wide or a regular. I've used wide on my KitchenAid and it works great for smoothies, etc. Google it. Try using some of the magic bullet type of recipes, their cook book is online somewhere, google it too.You'll probably have to adjust the blending times a bit.

  • Chew-Hoong

    4/30/12 1:22 PM

    @ Sue: Sounds like the size of your jars are large & small but have "regular" mouths. The Cuppow only works on "wide" mouth mason jars. We would not suggest cutting the Cuppow to fit your jars; won't seal well. You can find the wide-mouth in mason jars of various sizes.

    Was excited to received my three-pack of Cuppows -I ordered a couple to give away- and sad to discover they wouldn't fit any of the Mason jars I have. Clearly, I had missed mention in the promo that they are for wide-mouth jars only. Went back and checked - one visual when the camera is scanning up the jar near the beginning of the video, past the subtle "wide mouth" near the bottom of the jar; and one in print when you click through to the more detailed description of the product. Feeling foffed since I went ahead and ordered three to get the free shipping.

    @ Jory: We're sorry you didn't realize the Cuppows were just for wide-mouth jars. The Cuppow Team is already "prototyping" for the regular mouth mason jars. YAY!

    Quick question: Does it "seal"? Will I be able to make my drink at home and take it on the go with me without it spilling? I'm thinking like the travel coffee mugs that have the little flip-down part that keeps stuff from sloshing around while you're moving from A to B.

    Thanks,

    Christine

    I ordered the set of three for the free shipping BUT needless to say I needed three. Had to give one to my best friend/travel companion or she wouldn't let me ride in her car after seeing mine. The 3rd one will go perfect for that "OVER the HILL" sippy cup present for a birthday gift! I know I'll be reordering soon. Thanks so much.

    The rings are not always available, especially on items purchased in the store instead of being canned at home. Would it be possible to include rings with the lids or as a separate item?

  • Karen
    Karen
    7/9/12 1:50 PM

    @ William Harrington Since they are made specifically for Mason Jars, you always get the ring when you purchase the jars. But, if you want to use them with other jars, you can find the rings at any store that sells canning supplies! They can be purchased in sets of three, separate from the jars and can be found year around at a local hardware store. Just make sure that the lids fit your "generic" jar.

    with the health risks of plastics, i've been reusing glass jars as water storage containers for a while. using them as replacement for portable beverage containers is also a great idea. but where does one find the metal lid rings that the cuppow fits into?

  • Katherine
    Katherine – Grommet Team
    7/9/12 10:37 PM

    @ anon - the Cuppow fits on either wide mouth or regular mouth canning jars. If you have canning jars, but no metal rings, you should be able to buy them where canning supplies are sold.

    I am trying to figure out if these will fit an 8-oz canning jar. I will have to look and see when I am shopping tomorrow for the jars whether the lids are the same size as the 16-oz jars that say "regular mouth" on the box. (I am going to use 8-oz jars to drink 8-oz of fruit and vegetable juice hourly as per the Gerson Therapy protocol, and I will juice every morning to fill 12 jars). It would be helpful if they would list the sizes of jars that the lids fit, but I guess I will have to wait to order these Cuppows until I see the jars in person at the store tomorrow and figure out if the 8-oz jar has a "regular mouth" or if it is too small. Thank you.

    @ David: What a creative, healthy way to use the canning jars. We think the size of the lids are standard for all mason jars.

    Cuppow Wide: 3 3/8" in diameter

    Cuppow Regular: 2 5/8" in diameter

    If you find it to be different, please share with us.

    The Cuppows are a great idea, but are WAY TOO expensive. Nearly $25 for three *plastic* lids??? At about $10, I'd be a customer in a flash. When someone in China picks up this idea, you guys will be out of business. And that will be too bad. You can't make your fortune over-night.

    It's expensive to manufacture a product in the USA due to regulations....this appears to be a start up company....we can trust that the product is BPA as stated due to truth in advertising laws and USA guidelines. I personally try to support products developed and manufactured in the United States and I am willing to pay a bit more for these as they are adding to our economy and employing our workers...I encourage you to look at the big picture and consider your health and safety in the products your choose...there is no guarantee when you purchase products manufactured in other countries. We need to support our USA based companies.

  • Joshua
    Joshua – Special Guest
    9/28/12 10:51 AM

    @ Billie: The Cuppow is made of a durable stiff plastic that shouldn't discolor or take on any unpleasant odors. Ideally, it should be reusable indefinitely! They are dishwasher safe, but you should make sure to secure them because they are so light that they can easily get blown out of the rack.
