FIELD: transportation, process engineering.
SUBSTANCE: method of producing the vessel closing plugs consists in fabricating the plug on the basis of, at least, two-layer combination of solid-bed layers furnished with an auxiliary opening element. Note here, that the layer facing the vessel is tightly attached to its edge so that, with combined layers getting separated, a hole is formed to remove the product contained in the vessel there through. The aforesaid layer consists, preferably, from plastic material with the inner breaking strength in the location of the said hole lower than the adhesion with the other part of the plug. Note that the combination of layers in the said hole location is subjected to a higher-pressure and higher-temperature effects using a thermal welding device to up the adhesion in the aforesaid location between the combined layers as compared to the plug remaining crosswise section.
EFFECT: easier access to the vessel content, protection against bacteria and other harmful effects.
