why is there a hole in the bottom of the cup?

I do not think there is a hole, although at first it may look like that. After re-examining my own tumbler, I believe that small bump in the glass you see is actually the point at which the glass was connected to the rod used during the glass blowing process. Don't worry, it does not cause the tumbler to be unstable, as the bump is on the inside.

I believe it's for thermal expansion and contraction. If it didn't have the hole I'm the outer wall the air would expand when putting hot liquids in and possibly challenge the glass integrity. I have double walled Bodum glasses as well and they have a hole in the bottom too, but the Bodums have a rubber type plug over it for use in dishwasher.

It's not a hole. It's just a space between two glass walls. The purpose of the two walls is for insulating purposes.

The hole is to be able to put the blade on. Think about the blender cups, the bottom of this pitcher would be like the top of one of the cups. Make sense?

There aren't holes but there is an air gap between the top and bottom which produces an amusing sort of vacuuming action, like it's being sucked down through the bottom. Hope that helps.

What Ed Clearwater said-the hole is at very bottom of the device. And the entire hole goes about to the 1 cup mark on the 4 cup device.

it looks that you overfilled the the cup with ground coffee,try to have at least 3 mm clearance from the coffee grounds to the edge of the cup

don't know the wire connection to the cup becomes embedded and it no longer heats

The cup fits upside down within the carafe. The bottom of the cup becomes the lid of the carafe.

No it is separate. There is a drainage hole in the bottom of the cup as well.

I didn't find this happen to me. It's double walled so the temperature didn't transfer to the outside of the cup

There are no holes/openings in the bottom. I had to drill holes in it for drainage.

Hello mommymichelle5, Sorry for long delay, I miss this email, too many emails in basket. To answer your question; I do not know why there is a hole in the upper left corner, I see no real purpose. That is a good question. If you ever find out, please let me know. Thanks!

I occasionally get grinds in my cup when using any brand of K-cups. The foil top could seal around the piercing needle and the hot water builds up pressure so it squirts out the bottom hole with much pressure! Or we might need to pierce the top twice and make the hole too large?? Who knows! All you need to do is strain it with a tea strainer! It only happens to me about once a year. I love my Keurig anyway!

It doesn't open in the bottom. It has small holes at the bottom. Hope this help.�

I had the same problem at first then I discoverd you have to make sure the rubber on the top is pushed all the way down in the cup part and the little push top is in too so there is no air is leaking out when you push down

there are two holes provided on either side for the metal handle, there is no hole on the bottom

I've never had this problem. The spout is a small opening and the cup seal is very tight. In fact, I have the mug beside me right now. No issues here.

They have a hole close to the bottom edge to sip or drink from and a very small air hole at the top for air, but not big enough for a straw.
