Heinz introduced its octagonal glass bottle for the first time in 1889; the bottle was patented in 1890. While other glass bottle designs have existed, the octagonal glass bottle is still in use and is considered an "iconic" example of package design. In the United States, the glass bottle commonly used by restaurants holds 14 ounces (400 g) of ketchup. A small bottle containing about 2.25 ounces (64 g) of ketchup also exists for hotel room service and other situations where it is desirable to serve individual meals with a more personal or luxurious presentation than might be perceived with the foil or plastic packets associated with fast food dining. As ketchup has high viscosity and behaves as a pseudoplastic or thixotropic liquid, dispensing from glass bottles can be difficult. Tapping the glass bottle causes the ketchup to become thinner and easier to pour. Heinz suggests, on its website, that the best place to tap the bottle is on the "57" mark. The New York Times has also claimed that the tapping the "57" mark is the best way to cause Heinz ketchup to pour smoothly. Shaking the bottle or tapping in another place is also effective, however.
