The Pull-Tab Openner's inventor: Who is Ermal Cleon Frazer?

In 1959, one day he went to a picnic, he opened his beer with the help of a car buffer, and he thought of the idea of the opening ring here.

Canned foods were released in 1812, but drinks were not sold in a tin box until the 1930s. The first beverage boxes were made of steel and opened with a device that made a hole on the box; However, a second hole was required on the other side of the box to ensure the air output in order to flow comfortably. At the end of the 1950s, steel boxes were replaced by aluminum boxes; Although they still needed to be opened separately, it was easier to open the aluminum box.

In 1959, Ermal Fraze went to a picnic one day he realized that he did not take the “church key; He managed to open his beer with a car buffer. Before doing this, it is explained that the famous inventor said: “There must be a better way.”

Ermal Cleon "Ernie" Fraze (September 16, 1913 – October 26, 1989) was an American engineer who invented the pull-tab opener used in beverage cans. Fraze died in 1989 in Kettering, Ohio from a brain tumor, leaving an estate worth $41 million. Soon after his death, the family sold the Dayton Reliable Tool Company to business managers, but the business remained in Dayton. 

After a while, while trying to sleep a night when he missed the coffee too much, Fraze began to think about making a leverage lever attached to the tin box to eliminate the need to open a separate need. The idea that came to your mind was simple - a round-shaped rolling strip to the top of the box and making a leverage lever that will help to pull it out.

But the engineering was not that simple. Fraze, the founder of Dayton Relief Tool & Manufacturing, had a patent for the çalıştırma decorative cover design that can be opened by tearing up in 1963, as it has the necessary metal processing experience.

The decorative design of Fraze consisted of a metal piece with a metal piece with a metal piece, even though it was useful as a leverage, although it was useful as leverage). In 1965, the real revolution took place when Omar Brown and Don Peters made Fraze's metal piece - into a ring where the finger could enter - and simplified the tear lane on the box; They took the patent of both ideas on behalf of Fraze.

The opening ring was making his task flawless, but a lot of sharp-edged garbage was coming out. Then, when he was pressed and pulled back in 1973 and pioneered the lids in the box, Brown took this idea one step further. (The patent application of this invention was made on behalf of Fraze and the application was accepted in 1975.

In 1990, Robert Demars and Spencer Mackay (both USA), tin boxes "pressing and pulling back" opening, "the elderly or rheumatoid arthritis and for those with similar problems", they said it eliminated the patent of the inventions they said. The innovation here was to make a light protrusion called a moving puff. Thus, when the opening ring was turned to the right or left, these protrusions would be on top of the ring, the ring would rise as much as it could enter the finger, and the rising ring would also start the “pushing” part of the operation by breaking the seal.

DID YOU KNOW?

The reason why the top of the tin boxes is narrow is made of steel, which is the thickest and the most expensive part of the production process. The gradual contraction of the box reduces the size of the upper side by 20 percent.

1975 Brown, on behalf of Ermal Frazer, the "patent of the" patent of the binding ring of the box "was first produced in 1977.
