"Fáiscre", an early word that can mean "cheese", was derived from the
verb "fáiscid" = presses, squeezes. That verb has a Welsh cognate
"gwasgu" with the same meaning. I don't know exactly what the
reconstructed Insular Celtic form would be.

A wooden milk pail was a "derb" in OI.

A very common verb that covers those concepts is "gaibid".
NB: The citation form of OI verbs is the 3rd sg. present tense.
