I picked up one of these bottles to store denatured alcohol in (8oz not 3oz). link

I took it out for a quick one nighter with my son, and put about 5oz in it and then put it in a ziplock bag. This thing must have leaked like crazy because the inside of the bag was wet and I had about 2oz left when it came time to cook. The lid was on tight, squirter down, and no cracks in the bottle.

Does anyone use something different to store alcohol in?

Yep. a shampoo bottle or a 250ml or 500ml plastic pop bottle.

Diet Pepsi bottles of various sizes work very well.

Thanks for the ideas. A shampoo bottle sounds perfect (and cheap). Now I feel silly for asking/not thinking of that myself.

I use bottles very similar to that from REI, and they work fine. The 1 oz looks like that one, but the 2 oz, 4 oz and 8 oz are flatter. I think mine are Nalgene brand. I sometimes keep it in my food bag, even though I know that's not a good idea, but I haven't had a problem with leaking.

Perhaps I picked up a bad one. It is the 8oz and round, not the flat flask looking one, specifically because I wanted the squirting lid.

I've used those, and the flat 8 oz kind. But I always carry them upright in the outside pocket of the pack to avoid a lot of pressure on the bottle, and have sometimes put that plumber's tape on the threads before screwing on the lid. smaller pop bottles also work.

I use this 4 fl oz bottle a lot: http://www.rei.com/product/605499 I marked the sides in ½ fl oz steps to help me dispense the correct amount based on temperature outside.

I love the squirting lid you show. I picked up several lids from BPL IRC. I then use those lids on:
1. http://www.rei.com/product/402028 I like the flatness of this bottle. It slides into my outside pockets nice.
2. http://www.bottlewise.net/index.php?p=product&id=40&parent=0 And I like how this bottle takes up less room as the fuel goes down.

In all these setups, I have never had a leak even with pressure. Thus I never have to put it in a backup bag. That’s the nice thing about alcohol, if it does leak, it doesn’t eat/melt items in your pack.

BTW, try not putting your bottle into a Ziploc bag. There’s something about the physics of that scenario that wants to suck the liquid right out of the bottle.

Teflon tape on the threads works for me.

My favorite (and standard)...recycled contact lens solution bottles. Common (approx) sizes; 1/3, 1, 4, and 12oz. Bigger than that I use the same bottle that rubbing alcohol comes in (but not rubbing alky itself). Or Heet with the replaceable caps.

The contact lens bottles have a great dripper nozzle (removable) that will produce a nice, controlled stream of fuel. I've never had one leak...

Wow, awesome. I think that is perfect. Thanks.

I use the 8 oz bottled water bottles with the regular screw-off lid. They're very light, and unquestionably leakproof. They don't come with a dripper type cap, but I can take one of the flip-up caps off of another water bottle to use if I have to, but I've found that if I'm careful I don't need the dripper.

I 2nd the contact lens bottle. They are nearly perfect.

I just use a used plastic Poland Springs water bottle. Been using the same bottle for years.

I've had two of the 4-oz contact lens solution bottles leak. I used them only for contact lens solution, but I carried them backpacking or camping 2-3 weekends a month for at least a year before I had a problem. They will last a while but not indefinitely. The nozzle does work great if you need a very small, concentrated stream of liquid (such as cleaning off your contacts, not surprisingly).
