But what do you do when you have sunscreen on your burger and mayo on your back? I think this might backfire.

You could invent some sunscreen mayonaise.

That would make it more compatible to the American metabolism.

Or make it so we sweat sunscreen when we eat the mayonnaise (on fries?).

Mayonnaise on fries is British. It's probably related but we'd have to market it differently.

(I've noted that the covers on the Harry Potter books in Britain seem to be drawn for intelligent people, whereas the books in the US are far more cartoony.)

There's an offshoot idea actually. Could you make a pill or food that turns you sweat and or skin oil into natural sunscreen?

Well, you could have a weird color packet. Last I check all mayo packets were white.

Well now you only have a year under 102(b)... This counts as public disclosure.

Although, more seriously, I doubt it would be accepted. In order to be patented, the idea must be novel, useful, and not obvious. It meets the requirements for useful, but not-obvious and novel may be harder to establish. (Depending on any patents for single-serving condiment packaging, they may be phrased in general enough terms to be considered prior art)

I'm 100% certain that I'd find a way to make one of these explode when I sat down, covering my wallet, money and ID in a sticky mess.

Which would make it pretty tough to get into bars.

That idea's been done, but if you could develop a packet of goo that could be used as both ketchup and sunscreen, then you'd have something. You could put half on your burger, and the other half on your face. Huge time saver.

Awesome idea. Even more awesome that it already exists. Ordering some right now...

I don't think you can patent this...my school gives these out at any outdoor event. My friends and I usually collect a bunch and I keep them around -- in my purse, in my car, etc.

Individually wrapped sunscreen wipes are already in most pharmacies.

I actually carry sunscreen with me at all times. I use it maybe once a year, and I can't predict when.
