Comparison of Usage and Function
The plastic and metal coffee capsules typically are used in a non-removable receptacle on the brewing device. The capsules have an outer ring or rim that stays dry during use, allowing for removal and disposal after use without getting the user's hands wet or sticky. Handling of a used moist coffee pod is not necessary if the brewing device has a removable filter tray. This tray is removed after brewing and inverted to eject the used coffee pod.
Coffee pods, bags, and capsules can be sized for individual or multi-serving portions. In food service businesses, pods and capsules used with automatic brewing can help to provide consistency of product strength and flavor for customers.
Paper coffee pods such as those used in Easy Serving Espresso Pod or Senseo machines have the benefit of being a fully biodegradable product that can decompose naturally, while plastic and metal capsules such as those used in Keurig or Nespresso machines either aren't recyclable, or require additional processing to separate the plastic/metal container from the organic waste products.
Due to the high temperature water used for brewing, all types of coffee machines usually don't need to be disassembled and cleaned with soap after every use. Many capsule machines specifically admonish the user to not disassemble the machine or put their fingers inside the capsule receptacle, as the devices commonly use sharp razor-edge tubes or prongs for piercing the coffee capsule during use.

Famous quotes containing the words comparison of, comparison, usage and/or function:
“When we reflect on our past sentiments and affections, our thought is a faithful mirror, and copies its objects truly; but the colours which it employs are faint and dull, in comparison of those in which our original perceptions were clothed.”
—David Hume (1711–1776)
“It is comparison than makes people miserable.”
—Chinese proverb.
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
“Our father has an even more important function than modeling manhood for us. He is also the authority to let us relax the requirements of the masculine model: if our father accepts us, then that declares us masculine enough to join the company of men. We, in effect, have our diploma in masculinity and can go on to develop other skills.”
—Frank Pittman (20th century)
