Ketchup is a very important condiment in America. Every fast food restaurant has a very large amount of ketchup, and the ketchup industry is also very developed in the United States. For ketchup America is very important. The inverted ketchup is to allow consumers to enjoy the freshest ketchup, but also to facilitate the consumer access to ketchup, Heinz ketchup even put a bottle inside the ketchup flow out of the speed of the factory as they sell the standard.

I tapped frantically dozens of times to pour out the ketchup that had accumulated at the bottom of the bottle, and finally gave up at the expense of my wrist. Pouring ketchup is the most extreme thing in the world; either not a drop comes out or it gushes into the ocean. Opening a bagged ketchup is the same as biting into a real tomato; you can never anticipate which angle the juice will be bared.

In fact, the practice is most rooted in food safety. That's because U.S. restaurants, for cost reasons, typically purchase ketchup in barrels or large cans and dispense it into small bottles with a capacity of a few hundred milliliters on the table. Pouring it upside down allows diners to eat the fresher part of the bottle. It's easy to see how ketchup is an important part of the American diet. The barrel ketchup mentioned above can also be found in supermarkets.

Even in Collinsville, Illinois, where ketchup is produced in abundance, a 50-meter-tall sculpture of a ketchup bottle has been erected. The sculpture has its own popular social media accounts and a steady fan base. Quite a few annual festivals of the locals are centered around this giant bottle. It's enough to see how popular ketchup is in the United States.
