It's obvious on these photos:

...but we still haven't solved the release if you (like I) wished to use this in a SB session...hmmm! All these images are firing my imagination, but I can't see a solution to the basic problems:

- large/strong/clear/flexible plastic bags (those Asian babes look very petite!)
- timed release that doesn't require the constant running of a vacuum cleaner and the associated problems with overheating and safety

Oh woe is me!

This is a matter I've given a bit of serious thought to lately.

The matter of size. I thought of getting 2 of the larger sizes of bags and using a solvent based glue to join them together. This should create a air tight seal between the 2 bags with a couple of inch overlap it should also be very strong.

Doing this would create a big bag with 2 outlet's for air. I would replace one with a snorkel tube.

For a timed release I have had a couple of ideas, both involve making an air tube in one of the bags bottom corners. Using some of the bags same material you could cut a length, roll it over a toilet roll tube and glue the ends to make the tube easily enough. Now you have an air inlet.

To make a timed release from this you can either double it back over it's self and freeze it in place. Cruise would be sealed until the ice melted and would then let the tube open on its own.

Looping the tube again you could use a rubber band and a block of ice to keep is in place. Tying off the rubber band to an anchor point. When the ice melts some struggling could pull the band off.

Again with the doubled over tube you could use a magnetic door lock to clamp it shut. Using another timer to release it.

This would mean you only need to run your vacuum to empty the bag, they will then self seal.

Uncle: that is an excellent idea - I hadn't thought of using magnetic locks to hold the 'seal' closed, could be a serious contender for a revised design.

Ra: I've tried these before, the quality of plastic wasn't so great and the seal was difficult to set for inside (poor design if you ask me!😁), but I'm not writing them off yet!

thanks to all for comments - there is a plan forming....

Did you try to turn them inside out?

But the quality of plastic is indeed below average.

Tiny, but significant flaw in that idea - the vacuum valve is then on the inside and the wrong way around ... been there, thought of that.. DOH!

Yeah, indeed. I thought it can be reversed as well. Just looked at mine.
