Removing the seal you show has become a personal challenge for me too.
I experimented with all different techniques; but, I was late to the game. Before I found a workable solution someone else discovered that you could peel off the seal like the lid on a canned ham. Then, the problem became how to best grip the edge of the seal to do this.
Enter the perfect Hack: Seal Removal Pliers…
The needle-nose tips of these pliers have mating jaws that will grip any seal edge firmly, and the locking ratchet-bars on the handgrips maintain the pressure until the user unlocks them. Once locked onto the seal, the pliers are used much like a key is used on a canned ham. You just rotate it across the neck of the container; the seal wraps around the jaw pliers as you do it. When you unlock the pliers, the seal slides off.
`* Up to this point some of you might be thinking that these tools are called hemostats, not pliers. Actually, they could also be called fishing pliers for hook removal, pressure clamps
for fine model work, or even parcel-wrapping pliers since they excel at holding crossed ribbons in place as you tie a bow in them. As for their use in surgery, there are probably as many fly-fishing doctors who have such pliers attached to their fishing vests as use them in the O.R.'
I got a pair— satisfying.
