A glass container refers to a vessel made out of glass, which is typically used for storing or preserving food and beverages. It can come in various shapes and sizes such as bottles, jars, flasks, and vials, among others. The material used in making the container provides several advantages including its transparency, allowing one to see through it and determine the contents without opening it; durability, as glass is strong and resistant to breakage; and resistance to chemical reactions, ensuring that no flavors or odors are absorbed by the food or beverage stored in it.
