vacuumzione da tube

[TECNOMODEL]

Good morning to all,
I have a "particular" question, maybe more than physics or plumbing.
I am looking for a solution that allows a person to aspire a liquid contained in a container, bottle or bottle, equipped with a tube.
the difficulty consists in the length of the pipe, determined by the position of the container with respect to the person.
we can hypothesize a distance of 50/70 cm, a tube with inside of ø6/8.
without having done empirical evidence I feel that it is very difficult as operation, because of the large volume of air to be removed from the tube before the liquid arrives to the mouth. My assumption is given by vague memories of the laws of hydraulics, but now I can't frame what laws apply to the case.
First of all I would like to have some explanation about the phenomenon or indications on where to find material about it.
in second line I would like to set up the problem having some data to compare then with the solutions I will try to study to solve the problem.
Thanks to who will help me.

hi mountain backpacks often have the "camel bag" bags full of water with a tube connected to the shoulder for drinking without having to pull out the bottle... the connecting tube is of that length and sucking water is not difficult... the tube is empty only partially.
If you want to make things easier, it blows inside and the bag goes slightly in pressure and just open the valley at the tip of the tube to have the flow.. .

I had thought of those backpacks, but the jump is less, having it on the shoulder.
the valley you're talking about? I was thinking about putting one of them back so as to avoid emptying the pipe.

as rightly quoted by @rust there are many versions of these bags, hose, with valve, etc. and the tube can also be 1 m long. see this example.
However, the diameter of 8 mm seems excessive. . .
If you want to analyze the problem analytically you might be useful This is.

Thanks a lot, the link to analyze is exactly what I was looking for
