FIELD: packaging; storage.
SUBSTANCE: invention relates to a glass bottle. Glass bottle comprises a neck with a rim intended for fixation of the pouring sleeve of the closure device, wherein the rim is limited by an inner side surface, which also limits the pouring hole of the neck, and an outer side surface, on the side of which two, upper and lower, annular collars are formed on the rim, designed to prevent longitudinal movement of the pouring sleeve relative to the rim, wherein top ring-like bead comprises side surface and bottom surface while bottom ring-like bead has side surface and top surface and radial ledges to prevent pouring sleeve from spinning relative to rim. Outer side surface of the rim has a round section above the radial projections, the diameter of which is equal to the diameter of the rim section on which the radial projections are formed. Each radial protrusion has a side surface and an upper surface smoothly changing into the above round section of the side surface of the rim, smoothly changing into the lower surface of the upper ring-shaped bead, forming a ring-shaped recess designed to accommodate a projection-stop on the inner side surface of the pouring sleeve.
EFFECT: higher reliability of the functioning of the closure device at all stages of its operation, including at the stage of the first opening of the glass bottle.
