Fiona wants to know....

...what this symbol means:

She found it on the lid to a jar of applesauce. She said I could look it up on the internet (the source of all answers, obviously!) but I haven't had any luck so far. Maybe you know?

Doesn't three dots in a triangle usually mean heat? Or something like that ...

I saw an icon on a tube of toothpaste that I didn't recognize and e-mailed the company through their website. They got back to me within a couple of days. Maybe you could do that?

Three dots in a triangle means a lot of different things, depending on context. It can mean "therefore" or "ruins" (but, usually the triangle for these meanings is upside-down from the one in the picture). This isn't one of the several symbols I know for "heat", but that doesn't necessarily preclude it from meaning that.

I think the other part of the symbol is probably the place to start, though. It's more distinctive.

Isn't there a reverse image search out there, where you can try to draw an image and search for others that look similar? I was thinking somebody experimenting with computer image recognition had put up something like that a while back and it got written up on slashdot.

[hmmm....]

Ah, yes, TinEye, that was it. Might be worth cropping your image down to just the symbol, and maybe reducing the color depth, and seeing if anything turns up.

Upon closer inspection, I don't think TinEye is the one I was thinking of after all. This may have been it, but that only covers aviation photos, so it's probably not helpful, although the acronym CBIR does lead to an interesting Wikipedia article.

It may be a machine-readable symbol, to help the machine that puts the tops on the jars orient the tops so they will fit down on the threads molded into the glass. The jar probably also has indentations on the bottom that help the machine grip the jar and hold it in a standard orientation.
