The pop-top can simply changed its name to the hard-top can!
No matter how powerful a person is, he has to be careful when he pulls the can. If you want to open a can, you not only have to master just the right amount of strength, but also have some luck bonuses: if the strength is too small, the fingers can’t even pull the tabs open; but if the strength is too large, the tabs break, it will be lifelong. All skills will be sealed in this thin sheet of iron.
A broken jar that is the enemy of the whole world.丨imgflip
Canned food can not open the hardest hit area. Every time I open a can I have to worry not only that the nails will fall off, but also that the tabs will be pulled off, and I may really go crazy (Skr).
At this point, the furthest distance in the world: you and the meat in the can.丨Weibo
If Archimedes, the master of levers, came to modern times and found that people had spent thousands of years not using the principle of levers to open a tin can, he might have withdrawn his statement of “lifting the earth with a fulcrum” on the spot.
Not being able to open the jar is frustrating, but at best it only hurts your heart. For some people, the damage caused by this small pull ring is more than that .
This little piece of iron is really dangerous.丨References[4]
Who hasn’t been a soda can victim?
In the era when the cans were just invented, all the pull tabs were flip-out, that is, the pull tab was pulled down with the lid. At that time, using this kind of pull ring as a ring has become a classic part of romantic love stories. But in real life, it is not only not romantic at all, but also “hurt” a lot of people: we accidentally cut our fingers by the iron sheet that is pulled down, and the pull ring that is thrown away often hurts people for no reason. Griphook can be directly selected for the hidden weapon rankings!

Not to mention, of course, those pull tabs that go inside the body .
In the 1970s, pediatricians reported more than a dozen cases of accidental ingestion of pull tabs. The consequences of swallowing them are unimaginable: the sharp edges of the tabs can easily cut into internal tissue, and an 11-month-old baby even lost his life because of the affected aortic arch.
Generally speaking, aluminum has a low radiodensity and is easier to transmit through X-rays than other metals. It looks similar to soft tissue on X-rays, so it is difficult for doctors to find it through filming . There is a recent case report of a patient who did not discover a piece of aluminum in her body until the fourth year of abdominal pain. But the location of the tab is very obvious—probably because it has been in the patient for four years and has changed in nature. Doctors finally removed the ring through surgery.

No matter what kind of pull ring, breaking the pull ring is a world-class problem that can’t be solved. There are also some businesses who like to be “smart”, even pulling open the pull ring is challenging the limit of our fingers, not to mention the difficult action of pulling open next. Anyone who has been hurt by Griphook wishes this anti-human design to disappear from the world!
Does this kind of small pull ring really consider the feeling of fingers? ? ?
Wait, the world without the Grip could be tougher.
How do people open cans when there are no cans?
The tradition of packing food into metal cans has a long history, and people began to use tinplate cans for seafood and fruit in the early 19th century. At the time, there were instructions on the can: If you wanted to open it, you had to “cut a circle in the top of the can with a chisel and hammer “.
Trouble is trouble, but people at the time believed that canned food was the safest thing to do! If you want to open a can, people can only come up with powerful tools. After another 30 years, all kinds of can openers came into being, but for ordinary consumers, these tools are difficult to use and want to smash with a hammer. It wasn’t until 1892 that something useful was finally made!
This is the ” can key “.
Can Keys that can drill holes in cans.丨cantechonline.com
The can key is similar to a special version of the chisel. Using it to open the can is actually to force two holes in the can. In 1925, people finally invented the greatest invention in the canning world – the two-wheel can opener.
But these can openers are still “outsides” of the can. Not having a can opener on hand when you want to eat a can can really drive you nuts. Engineer Ermal Fraze was one of the victims. In 1959, he was on a family picnic and wanted a beer, but he didn’t have a can opener and had to pry it open with a car bumper.
But he is adamant that there must be an easier way to open the can.
After a sleepless night, he made cans. The ability to instantly open cans without additional tools was a huge improvement at the time. And the pull ring has gradually evolved into a better and better pull. For example, the pull ring is getting bigger and bigger, which is more suitable for fingers to pull; the riveting for fixing the pull ring is also stronger.

Until the late 1970s, the built-in pull ring came out , and since then it has gradually replaced the pull-open pull ring and has become the mainstream and dominates so far. The pull ring left on the tank body not only solves the problem of recycling part of the pull ring, but also avoids some human injuries.
But the flimsy connection points did not prevent the pull ring itself from falling off, and these pull rings scattered around the world even spawned a ” grip archaeology “. Interested in Grips, Jobbe Wijnen collected more than 8,000 Grips, found and classified them.

Chobe’s collection of pull rings is still going on, but in addition to archaeology, can someone develop the “successful learning of opening cans” as soon as possible!
It really doesn’t work…
Pull the tab with the pull tab
How can people who are good at inventing tools stop there? Faced with the problem that the pull ring is difficult to open, a smart human has an idea: I can get a big pull ring to pull the small pull ring !

Online “can openers” vary in style, but they all do the same thing: give the tab an extra “handle”. Unexpectedly, the development of soda cans now requires tools to be opened.
For cans or cans with a broken tab, although it can be poked with some hard tools (metal spoons, straight lines), there is still a certain danger. Especially for soda cans, the Internet will also teach you to rub the outer surface to let carbon dioxide “burst” the opening. This method of “blasting” cans is also risky.
You might as well collect these hard-to-open cans with broken pull tabs. After a few more breaks, you will definitely want to buy a special can opener…
