Travel bottles and spilage

[Primross]

I may try using some thin sterile gauze and then painters tape. Not sure if the gauze will to porous over the nozzle to prevent the pressure change that I am trying to negate.

Then again, I may end up using an Otterbox or some sort of water proof type box but I am trying to stay compact and light.

Like I said I have never had an issue. If I was going to use something I would select cohesive bandage I'm a nurse and I use this for lab vials to protect them for important specimens. It doesn't use adhesive it just sticks to itself I'm sure you could find some cheap in a dollar store or Amazon

Update,

Round 2 testing failed.
I used 3 10ml bottles and 1 2ml togo type bottle, all from PXS.
Two of the 10 ml bottles contained pheromones and the third was witchhazel. All were primed for spray and contained 3+ ml of liquid.
After flying 2 legs and arriving at the hotel, at least half of the liquid from the 10ml bottles had leaked into the ziplock bag.
The 2 ml bottle appeared not to leak.

Two legs home and the most of the liquid was now gone from the 10 ml bottles but the 2 ml bottle still seems not to leak.


More testing required.

Hmm, I never get any leaks with 10ml bottles. Was there any liquid in the tube already?

Yes, the was liquid in the tube as the bottles were primed to spray.

That is a great idea and exactly why I put up this thread.

thanks happy to help

What if you spray any liquid in the tube back into the bottle? I always do that so I get clean shaken well spray and it may solve the leak.

You mean to say it leaks because the sprayer is primed?

It could be the cause.

I never hear that before but it could be the case

I had thought about doing that but inevitably I will forget to spray it back in the bottle.

I spend (on average) 3 nights a week on the road.

Yes.
I am experiencing a siphoning effect due to the pressure differential between the bottle (higher) and the cabin altitude (lower).

[Bloodburn]

Because how could it leak out if the cap is well closed (unless it's that flimsy 2ml). Pressure could have built up inside the bottle then push it out through the tube.

The 2ml is always flimsy

Yea, I hate that bottle. The only 2ml I carry is NNPA.

Its the opposite. The pressure is inside the bottle is atmospheric or about 15 psi and when you get to altitude in an aircraft the pressure drops to around 8 psi. Fluid dynamics comes into play and things move from a higher pressure to a lower pressure.

Funny enough, the 2 ml bottle don't seem to leak.

So it depends on how much liquid it contains also

Thank you for clarifying that.

That would appear to be the case in my not so scientific approach.

Gotcha!

Hmmm, no air, no outsiphoning I thought it was evaporation but atmospheric siphoning makes more sense.
