The word 'brimmer' originates from Middle English 'brimmer', which is derived from the verb 'brim' (meaning to fill to the edge or brim). It refers to a vessel filled to the brim, particularly with liquid.
Think of a cup filled 'to the edge' — that's what 'brimmer' means, a vessel filled to the brim.
