A ketchup bottle is a container designed to hold and dispense ketchup, a popular condiment made from tomatoes, vinegar, sugar, and spices. Typically made of plastic or glass, these bottles come in various shapes and sizes, with the most common being the squeeze bottle, which allows for easy pouring and control of the ketchup flow. Ketchup bottles often feature a flip-top or screw cap for sealing, ensuring the condiment stays fresh. Many bottles are labeled with nutritional information and ingredients, making it easy for consumers to understand what they are using. The design of the bottle has evolved over time, influenced by consumer preferences and advancements in packaging technology.
