Coffee Pots That Won't Pour Properly

08/26/2021 7:13 AM

I have noticed on all brands of glass coffee pots that they cannot be poured without

dripping over the edge of the pot.

I have tried many different brands and they all

have the same problem.

If you fill the pot up 1/2 full,it will pour properly if you pour VERY slowly.

I complained about this to one company,and they said it must be a defective pot,and

they sent me another one..exactly the same.A good honest gesture,but it did not

address the real issue.

I got the same response from another company.

A pour spout is an ancient craft,but the skill apparently has been lost in modern design.

I realize the constraints of max-for-the -minimum in modern manufacturing,but how

much could it cost to raise and extend the spout lip a few millimeters more?

Just take a look at the pour spouts on glass coffee pots,they seem to be designed to

drip back toward the pot.

Obviously the designers have always bought their coffee and never made a cup for

themselves using a glass pot.

I prefer a percolator,but they are too slow and frequently fail with a thermal fuse

going open.

Perhaps more public complaints about this issue will motivate them to modify their

design.

Several friends have expressed the same issue.

Has anyone else had this problem?

Try lifting the lid before pouring.

RIXTER has the right idea. That's what I do. The reason that we are having this issue is that the spout channel design is too wide and not deep enough.

I never have a problem, just lift the lid like Rixter says....

I just tried that "lift the lid" method with my toilet and the water turned yellow.

You should buy a 5 FL OZ bottle of Kikkoman soy sauce to see how the Japanese have perfected the non drip spout and adapt the principle of it for your coffee pot.

Their bigger size soy sauce bottles also have non drip spouts of a different design.

KIKKOMAN non drip pouring spout

Also a problem with the spouts on many glass measuring cups of the type shown below.

What I have noticed is that if the pouring spout area is "blunt", it is guaranteed to dribble down the outside face of the measuring cup. If the spout has a nice sharp cut-off with enough horizontal travel and necking of the path to increase the velocity of the fluid, there is a better chance that it will pour cleanly. The manufacturing issue with this is that it takes more care and time to shape a better spout.

I wonder if that would change if the CEO of the company had to pour red wine from their product over their finest table linens?

I've noticed the older glass measuring cups in my collection tend to pour better than the newer ones. (They don't make them like they used to!!)

You are right about the sharp edge.

The reason the drip,even with the lid up on some models is the Coandă effect,which

means that a liquid will follow a curved surface,and the spout lips are slightly

rolled,insuring that the liquid will drip off of the edge.

I can pour a cup without getting it on the table by putting the bottom rear edge of

the pot on the inside edge of the cup when pouring,but I should not have to do this.

I have tried to lift the lid when pouring,but it requires two hands to avoid dropping

the lid in the middle of the pour(Arthritis) I can remove the lid and get a good

pour,but why should I have to do this because of P-- Poor design?

It isn't just coffee pots, measuring cups have the same issue. But none are as bad as the gasoline containers

Pour faster. You need enough velocity to overcome the "sticktion". The cup will have to be tilted enough to catch the resulting wave and keep the coffee from splashing out on the far side.

Happy caffeinating!

You could avoid the whole issue by using a pump thermos....I have one of these when I want to keep the coffee hot all day....can't do that on a burner, ruins the coffee....

Good Idea.

Now all I have to do is get it into the thermos without dripping.

Heck,I may just go back to making field coffee,and forget the pot.

A few grounds between the teeth is good for you.

Yes the white teeth thing has been done to death, maybe you can start a new trend...?

Sure would save a lot of money on those expensive whitening strips.

Oops, it seems somebody beat us to the punch...

It seems teeth have now become a fashion accessory....

Who will be the first to suggest a new color? I think a white metal flake might be interesting...

I claim prior art rights on this, anybody wishing to purchase, contact....

I totally agree with the others comments!! I have noticed the same issue, and I have tried to raise the lid, with mixed results. Just the correct speed of pour and you can have a no spill situation, but try that at 3am and, well, you get the picture. I have taken to putting a paper towel under the pouring area on the counter just so the Mrs. isn't having a fit. I do hope that somewhere a coffee pot engineer sees this and heeds the advice.

It would insult their ability as an engineer by admitting a mistake or lack of common

sense that was plentiful even in the stone ages.

1000+ year old pottery had good pour spouts.

It will not be done if it required new tooling and cost $.0000000000000001 per pot.

Money is king.

That picture proves faulty design.

That pot is only half full..try it with a full pot.If you tilt the pot back a little, it will drip.

YES !!!!! Exactly.

That is the problem I have with the measuring cups as well.

I don't have that problem! Because I don't drink coffee. Perhaps if they made the "spout" a bit more pointy? But then they would have more breakage! Is the customer really always right?

Some people say coffee makes them hyper,and nervous.I don't have that problem.I learned how to cope with the shakes when I worked in a sewing machine factory..My job was to thread the machines as they came down the line..while they were running.

I had to drink a lot of coffee to make production numbers.My problem was when I didn't drink coffee..I began to un-shake...like an old car that shakes at 35 mph,then smooths out at 60mph,then when you slow down to 35 again,it shakes worse.

I missed my usual gallon-per-day intake and I had to give up brain surgery.

My patient went into politics.

As I said,pour spouts have been around for thousands of years,a very mature technology

There is really no excuse for the present state of the art to have deteriorated to it's current condition.

Get a Keurig. That will solve the pouring problem.

I actually have a real Keurig brand coffee maker, however it is the one that does both single pods and a full pot. The coffee pot actually works the opposite as many have stated. If the lid is kept shut, it doesn't leak. If you flip open the lid, it leaks all over the place!! Truly a strange dilemma, though now that I am used to it I have adjusted and just don't open the lid.

Can any of you remember the Engineer who designed the tea pot that poured well and retained its lid from falling into the cup. I know this was of porcelain, but could still be produced in Pyrex type glass? If not I'll see if I still have the references anywhere.
