Question: Can't you just sip from it or you have to use the cup on top or something? Can't you just sip from it like a regular bottle?
Document: I also don't think the inside part that you can't see (it's between the top and the main part of the bottle) screws in very tightly, but in any case, I have't had any problems with leakage so far, and it's been two weeks. I use it like every other day. It's incredible. My friend was so amazed she's like &#34;I've got to buy one too!&#34; Wish it could hold more but I don't particularly want to buy the huge 32oz one.
I like to sip hot coffee all day long, and I can't stand the bitterness of coffee left on a heater. I had an expensive coffee maker with a thermal carafe, but the coffee cooled within a couple hours.When the expensive coffee maker gave up the ghost, as do all coffee makers after a couple years of daily use, I bought the cheapest $18 coffee maker I could find (with only an on-off switch) and ordered this 34-oz high-vacuum Thermos.
Seriously, this thing is from another planet. Will keep your good piping hot or cold or lukewarm if you like it that way, whatever you put in, you are getting out within a 12-16 hour time frame. I think the 24 hour rating is a bit over the top, I suppose if you don't actually open it for 24 hours it will hold the temperature, but during regular use of pouring 3-4 times per fill 12-14 hours is about right.
Originally bought it for my husband for him to use in his lunch box, but it is just a smidge too long for it to fit so he never used it. I took it over, but I never use the lid. When I use a regular old coffee mug the coffee would get cool/cold within a matter of minutes. With this, I put hot coffee in, and I can sip off of it and it will stay hot/warm for hours.
Now I never use it. It's a classic-looking thermos with a slightly retro look. I loved it. Then after a while the plastic-lined cup on top started to smell very funny and very bad. Something weird about the plastic. Don't know if it's toxic. Made in China, and you can bet I will not be drinking out of it anymore.
This 26 oz. Thermos is the perfect size. I use it to take coffee and tea to work.I sip coffee all morning and it stays very hot. The easy pour lid is great. Just give the stopper half a turn and the beverage pours out without leakage or drips. I use the lid as a cup which holds a perfect amount. The bottle itself is easy to carry or to slip into a tote bag. I highly recommend this product.
I use this thermos with coffee and hot tea.The mouth of this container is small. I can't fit my hand in it to scrub it out. Like any container for coffee, it may get build up over time. I use anOXO Good Grips Bottle Brushto clean it out. Use a little bit of dish washer soap and hot water with plenty of rinse water.I have no complaints about this thermos. It looks and performs great.
I often use the screw top as a cup when not at home. It's not ideal, but it works! As far as cleaning, it's very easy. I just make sure to do a normal wash or at least rinse the thermos out shortly after each use so nothing cakes on the bottom. I often add milk to my coffee in the thermos, and have had no issue with that gunking anything up. If I ever lose this one, I'll definitely be buying another just like it.
PROS: Keeps drinks warm for hours. Cup fits well on the top. Clearly quality construction.CONS: Such a shiny surface dents pretty easily. Also, its not QUITE as lustrous as the picture indicates, although it still has a gorgeous brushed steel look. The stopper now squeaks like crazy when I twist it in to seal the container.FINAL VERDICT: Worth the $35, would recommend again.SUMMARY: I use this thing every day in school.
First bought Thermos Nissan several years ago in larger size after reading review on CooksIllustrated and exceeded my expectations because it kept coffee hot, hot, hot all day long and never leaked in whatever position it lay in the car or carrying. Cap is easy to remove (not like ThermosNissan coffee travel mugs, which can be difficult to loosen and remove), top cap is perfect size cup for drinking out of. My Thermos Nissan thermos never dented, despite hard use.
Answer: I just sip from it. I never use the cup.
