k-cup rim opens up during brewing

I have trouble with my k-cup spitting grounds inside the machine where the k-cup sits during brewing.

I don't believe the problem is the puncture needles or the top gasket. I have cleaned and checked both of these, many times, and the needles seems to be puncturing normally. I think the problem is the k-cup ITSELF.

I have observed that, in about 2-3 out of every 5 cups, the top rim of the k-cup actually separates... so, the leakage is not coming from the needle hole area. The leakage is coming from the edge of the k-cup. It is as if there is too much pressure INSIDE the k-cup during brewing, which forces the top covering of the k-cup, causing it to separate from the plastic cup.

@ljpne to much air inside the k-cups can cause this but that would be a manufacturer defect which we cannot fix. Change your brand and where you buy the K-cups. See if it continues. If your K-Cups have a domed, rounded top use a small needle and puncture the top before using it in your Keurig

If it does, you do want to clean the puncture needles. your Keurig has two, one on top and one on the bottom, If anyone of these two is clogged you will get a K-cup explosion due to excessive pressure inside the cups. I would start by cleaning the puncture needles since that would be the easiest fix. How to open and clean Keurig Coffee Maker
