- One who purchased a bottle or tin-can filled with food or beverage, may use them as is and is not required to empty them upon purchase, even if the bottle or can were purchased from a non-Jew and were not immersed in a mikvah.(Tzitz Eliezer, VIII:26 and other poskim)
2. Some say that one may even re-use such utensils without immersion after they were emptied of their original food content. (ibid.)
