Doesn't it look just like a paint scraper!

That's basicaly what it is. But with a few of differences the blade needs
to be quite stiff, most paint/paper scrapers are too flexible. It needs to
be fairly broad, say around 3" so the force to ping the seal is applied of
a reasonable area and won't cause the scraper to dig into the soft
plastic. The edge needs to be fine but not sharp to get into the tiny gap
without cutting the plastic if slightly misaligned.

You forgot the main difference, the price needs to be £23, instead of 99p
