I'm reading your question from an automatic translation, so sorry if I got your meaning wrong. A glass is made of glass, and does not have a handle. A cup has a handle usually, but can be handleless, as long as it is not made of glass. A larger cup, with relatively straight sides is usually called a mug.

You would usually translate 'copo' as 'GLASS' - especially if it is for a cold drink : beer, wine, spirits, juice, cocktails etc. A glass of wine, for example. Glasses are usually made of glass and have no handle.

Cups are usually for hot drinks, and are often - but not always - ceramic and with handles. You drink coffee out of a cup. If you get a coffee 'to go' it might come in a paper or plastic cup. Babies drink out of plastic cups with lids and handles.
