Has anyone seen a…

Does a silicone collapsible bowl/container count?

Maybe take an old cut-down Platypus and add an Anylock-style closure?

Ziplock bags can handle 190f (start to soften at 195f). Maybe not durable enough, but might be.

A sous vide silicone bag should work, it won’t be light.  My 2 cents

Re-use a freeze dried meal bag.

I would experiment with the suggestion from Balagan.

The reason is that I found the zip lock bags to be a bit too thin and leave a plastic taste and those silicone bags seem all to be i lbs or more.

I don’t detect a taste with hot drinks from the Platypus type containers. (obviously that is subjective)

I’m not sure about the boiling water bit but I have used the 24oz version of this for a couple of years now.

can you seal that ?

HDPE will handle boiling water, so you can dumpster dive in the #2 plastic bin at the recycling center.  Some of the better ones I’ve noticed (due the wide mouth) are Gatorade container (once holding the powdered drink mix).  It has a screw top but I wouldn’t say it is water proof – more water resistant.

Somewhat heavier, but also sturdier (and often HDPE) are the jar that protein powder (for bodybuilders) comes in.  If it says #2 HDPE on the bottom, it’s good to well over boiling and well under -40.

Beyond that, if you want truly waterproof lids, look at Nalgene lab ware.  Seems to me you want a wider, shorter container than the usual 1-liter HDPE Nalgene bottle to make it easier to mix the food and then eat it.

Brendan—I’m curious, what is your thinking behind this? Is it to avoid having to clean your pot while still having to clean this elusive kitchen product? As a (fellow?) freezer bag cooker, I’m interested in how you see this working for you. Thanks!

David, is that Gatorade container soft sided ?

Doesn’t seal. ☹️ Need it to seal for a couple reasons.

Good idea. Might need to try this.

Pretty much what I’m looking for. Thanks. Need to order one. Check out weight and how well it seals.

👍👍👍

Hi. I rehydrate all my dinners (hot) and most of my lunches (cold) and breakfasts (cold). While this saves me a lot of weight, the downside to this is that these individual bags take up so much space. I am going to experiment with repackaging my food in much smaller bags, and then using a container for all cold and hot rehydration. For it to work (and save space), it needs all the features I mentioned above. I think this approach will save me space and allow me to push my food carrying capacity up by another day or two—or even three.

Dan, how easy do you suppose it is to clean the food dregs out of that bottle?

Fill 1/2 with water, shake vigorously and then drink the dregs.

Think about it Gary, what do you have to offer that meets these requirements???:

I’m looking for a soft sided container to hot soak a meal in it. So, it must:

1. be soft sided
2. be able to handle boiling water (212 degrees)
3. be sealable (while the food rehydrates)
4. be durable (needs to be up to long term use and cleaning)

Seems you don’t actually need a true seal on the container; you just need to close it, as a lid on a pot does, to prevent convection cooling.

Given that, any sort of bag can be folded over and held w/ a small binder clip or rubber band.

You could try making your own bag w/ a vacu-sealer (aka seal-a-meal).  That plastic is durable and fine for boiling.  Use the film wrong side out so you don’t have grooves getting filled w/ little bits of food.

3 possible problems I see with that bottle

1 it’s 23cm high (9″), maybe 21cm (8.2″)once the cap is remouved but that is the size of a long spoon

2 it would be difficult to clean from food remains.

3 looks to me that you can only partialy remouve the top giving you a 1 inch or so opening

on top of that 500ml /17 oz could be a bit small for some

Franco and Gary hard to please blokes. How about this one:
