Question: Do Snapple bottles, pickle jars, and other glass utensils that are purchased with food inside require t’vilah?
Short Answer: Most poskim do not require the purchaser to tovel the utensil unless he plans on putting other food content into the utensil. Poskim are split on whether one may pour back the emptied contents of the utensils without first toveling the utensil. Rav Moshe Feinstein zt”l, however, even permits a purchaser to put other food content into the utensil without toveling it first.
