The invention is based on the object of a passage and to create a non-return valve for beverage containers that is completely hygienic and through the spear its mode of action cannot be impaired and, moreover, it is particularly easy and cheap to hemastelle is, but at the same time a light identification of the container enables. This task is carried out with a bunghole screwing exercise for beverage kegs solved in that the screw connection consists of plastic and is preferably provided with a magnetic valve. * As plastic, a hygienic Flawless, snacks-neutral plastic that can be heated up to approx. 120 ° is used.

You will find an example below explained in more detail, with all features being essential to the invention individually, alone and also in any combination with one another are. »The drawing shows a vertical sectional view a bunghole screw according to the invention

The dust plug 7 is removed before tapping the barrel. It protects the solenoid valve when the barrel is being transported, and while the barrel is loitering, it protects against dust.
