The invention from 1858 that became necessary after the 1810 invention of the tin can was the can opener.

The can opener allowed for easy access to the contents of the can, making the use of canned goods more practical and convenient.
== == how do you use a can opener
In a tin opener, the fulcrum is typically located at the pivot point where the lever arm of the can opener meets the body or handle. This pivot allows the lever to rotate, enabling the cutting wheel to puncture and cut through the metal lid of the tin can. By applying force on the handle, the user creates leverage around this fulcrum to open the can efficiently.
The tin can opener was invented in 1858. This was necessary after the invention of the tin can 48 years earlier, in 1810.
Well, I'd call them a tab collecter.
