My K-Cup is a reusable cup and filter that you can fill with your own ground coffee, made by Keurig. Ekobrew also makes Keurig-compatible ones, which come in standard (mostly plastic) or stainless steel.
My-Cap sells caps that allow you to reuse single-use pods (from Keurig or Nespresso) many times.
Tassimo is more limited, but you can reuse T-Discs if you wash them carefully and preserve the barcode.
This applies to Coffee pods.
