Can anyone enlighten me to the meaning of the word cuyler?

It’s amongst entries of an inventory of the royal treasure and these are pantry items. Here is the entry for context:

R 789 xj cuylers d'argent enorrez, du poys, xxiiijs.

Can these items be bowls/dishes as it’s similar to ecuelles. I’ve Googled and use both Middle English and Anglo-Norman dictionaries but I’m still none the wiser.

Many thanks in advance.
