Easton's 1897 Bible Dictionary:

Cruse
   a utensil; a flask or cup for holding water (1 Sam. 26:11, 12,
   16; 1 Kings 19:6) or oil (1 Kings 17:12, 14, 16). In 1 Kings
   14:3 the word there so rendered means properly a bottle, as in
   Jer. 19:1, 10, or pitcher. In 2 Kings 2:20, a platter or flat
   metal saucer is intended. The Hebrew word here used is
   translated "dish" in 21:13; "pans," in 2 Chr. 35:13; and
   "bosom," in Prov. 19:24; 26:15 (R.V., "dish").
