What do you call portable, nondisposable, sippy cups for adults?

Eco friendly water transport system?

I call them reusable water bottles

I hereby call it a “lippy cup” since you put it up to your mouth!! :)

I’ve seen them called “traveler’s mugs”. I don’t really have a set name I use for it.

Thermos?

Back in the day, they were called “thermoses.” I believe “travel mugs” is the most common terminology I’ve heard recently. I wonder if there will be a brand that leads the market so that the brand name is the common name for the device (like “Xerox” or “Kleenex”). PortaBotty maybe. Snap! Ucme.

Reusable coffee cup with a lid?

I don’t think of a thermos as having a place to sip from.

Insulated beverage bottle?

I don’t think of a thermos as something you drink out of as much as something you pour out of.

I guess “Traveler’s mug” is pretty descriptive. Although it’s pretty clear it’s not instantly recognizable.

Most people I know just call them coffee cups.

@laineybug Doesn’t help me. I need to distinguish it from the open top kind. I don’t want my story to be slowed down by,“he handed me a coffee cup with a screw lid.” It sounds like ad copy. And even with that it’s not clear whther you can drink when the lid is on.

Reusable mug, lidded mug, spill-proof mug, insulated cup/mug, travel mug, lidded tumbler, sealed mug, sip mug,

We usually just call ours “The mug for the car” or “Car cup”, since we use them for water and other drinks besides just coffee.

Since your character is handing someone a coffee, I’d go with something along the lines of spill-proof or travel.

In Holland we call those bottles bidon (which translates, according to a translation site, to canteen).

Travel cup is what we call them.

@SpatzieLover I think there are several there I could use. Thanks!

You’re welcome. ;)

@rebbel In America we use canteen usually to mean something we would bring along on a hike or for the military. Just for water usually, not insulated. It can also mean a very casual restaurant, but it is used that way in only specific situations, the average person would not use it that way.

Insulated mugs.

“He handed me a coffee to go cup.”

Commuter cup

Travel mug

Water bottle.

Coffee cup.

I just call it a mug. The coffee shop at work sells them and you get a bit of a discount at the coffee shop if you use one of those rather than their crockery or a takeaway paper cup.

Travel mug is the term I’m familiar with. Which is weird, really, because mugs should have a handle, and a lot of the travel mugs don’t.

Peet’s Coffee calls them tumblers. And some they call travel tumblers.

Some call them ball warmers.

Interesting @woodcutter. Handy in the winter in some places no doubt.

Travel mug.

@woodcutter just hope you don’t have a spill.

Travel tumbler or travel cup

When I got my coffee this morning I remembered I often call it a “go-mug” or “go-cup”.

@zenvelo I like “go-mug.” Would other people recognize this?

@6rant6 I think it’s a pretty well understood term.
