food rehydration container?

Ziploc makes a version that has a twist on lid. Try those out! They are of the right size and microwave safe….

I've tried those twist on lids for the Ziploc 2 cup container and they do allow a bit of liquid out when shaken…too bad cause they are fairly light.

Watching this with interest as I too am interested in what others are using.

Not the lightest, but Nalgene makes a wide mouth 16 oz. bottle that has a screw in lid that allows no leakage.

I have a 600ml mug that has a leak proof lead and a steam valve. With 500ml of boiling water in it , the lid pops up a bit but still remains tightly on. It is a Decor container , about $5. (I think made with polypropylene )
Not light at 85g/3oz, but maybe a lot easier to clean and more robust than the Ziplocks.
You would need to do some shake tests…You could cut the handle off, or get one of the bowls.
For the Twist And Loc containers, maybe a piece of bicycle tyre tube could make the lid "watertight" ?

On the threads of the container use teflon tape (plumbers tape).

The Caldera Caddy is wonderful.

The Nalgene Canteen has a wide mouth screw on lid, is watertight, and can handle boiling water.

Thanks Sarah! I got a Ziploc screw-top container, verified that it does leak when shaken but added some teflon tape to the screws and it works perfectly. And nests in my pot with my cup inside quite nicely.

Great! :-) Good to hear!

Just a follow-up on my use of the Ziploc screw-top container with a teflon tape seal. Indeed it does work in practice. However, I find that I have to replace the teflon tape after each trip. The tape can only be applied to the screws on the container and not the lid because it doesn't actually stick (it acts like food wrap in that tension is important). Putting on and taking off the lid abrades the tape enough to wear it away in some places after about 10 times then it will start to leak. I usually get some water pretty hot, pour it and the dehydraded food in the container and put the lid on right away. The air in the container will cool and create a seal which prevents leaking. But try not to handle the container (ie put it in your pack) until it has a chance to cool a bit because the plastic is pretty maliable when it is warm and you can easy cause a leak if you jam it the wrong way. Buy the narrow teflon tape if you want to use this system – you only need to seal the screws and anything wider is a pain when you are washing it out.
