This character is a combination of 木 wood, here meaning wooden item, and 不 not, here working phonetically to express "hold." Together this gives "wooden item for holding," or a "wooden vessel." From the beginning 杯 was associated with a "wooden winecup/goblet," and is now also used to refer to a "cup(ful)" in a broader sense.
