I actually know this!!! I actually know too much about this!!! I can’t actually believe there is something so random on here that I was directly involved with at the very beginning. I was one of the first press mechanics involved with setting up the manufacturing line (and purchasing the press that started this.) This has likely evolved in the 25-30 years since i was involved, but here are some nuggets of information.

Several of the answers to what these are, have already been answered within multiple responses. The dots are multi-purchase. Their first purpose is to deflect anything that might catch the tab, snag it, and accidently break the seal (which the pressure needed to do so is tested often). The second is to help align the lid as it goes through the press stages for the tab placement (the lid center is flat with the rolled outer ring housing sealant) before it hits this press. There are multiple highspeed steps of the press, forming the tab, adding the rings, dimples, the tab itself to the lid, and finally ejecting it out to the track towards the testers. Third, when you pull back on the top the dimples also give it a location to “crease” the top allowing better leverage to finish pulling the top free.

The rings themselves are structural in a way, but more importantly are for expansion if the can is deformed due to being dropped or temperature differential, minimizing the risk to the breakable seal, as well as also enabling enough space for a person to get their finger tip under the tab to open it.

In my mid 20’s (mid / late 1990’s) I worked as press mechanic for a can manufacturer in Menomonee Falls, Wisconsin (USA) that manufactured tin cans for a majority of the major canning companies. One of them was Campbells Soup. I was hired to set up a new line specifically for a new Campbells soup with a “revolutionary” pop top. There were four of us (one to set up and run it each shift, my shift was late-week evenings) that went out to Dayton Ohio for a bit to test and purchase the multimillion dollar press and tooling to actually do it. From there, it was a matter of setting up the highspeed line (which involved pressing of the coated metal (also done inhouse) sealing of the ring, punching and pressing the lid & tabs, adjusting the tracks (which was an absolute jamming nightmare for a long time), pressure testing the lids, and finally packaging). Then testing, running, working out the bugs, etc. until it finally worked efficiently. Which took a very long time. I quit a few years in by the time it was all worked out, but was directly involved with much of the early set up, trouble shooting, and grunt work. Working the issues out of it was so frustrating after a while, that it motivated me to go back to school and start a new career. lol.

So yeah. Now you know too much about pop-top tin cans :)

The law assures that only law enforcement agencies will investigate reports of misconduct by law enforcement officers.

Well boys they got us. Guess there’s nothing we can do as long as they call it illegal.

I actually still have mine somewhere. I didn’t use it much, though.

I’m still waiting on my Soundband headphones.

Clearing charges of people convicted of this is nice and all, but why aren’t we prosecuting these cops for racketeering or production and distribution of narcotics?

TLDR:

"I worry that we are building a society of hypochondria and over-monitoring of our bodies,” she says.

Dr Salisbury says there can be a large number of reasons why we might temporarily get abnormal data such as an increased heart rate, whether it’s a blip in our bodies or a device malfunction - and many of them do not require further investigation.

“I’m concerned that we will be encouraging people to monitor everything all the time, and see their doctor every time the machine thinks they’re ill, rather than when they think they’re ill.”

Looks like a perfume shop, which is made to make ypur skin smelly.

I think Nvidia is noticing Microsoft killing it’s OS for gamers and enthusiasts, and is worried AMD will overtake them when people switch to Linux.
