UNIT FOR CLOSURE OF BOTTLES WITH LIQUID AND CLOSING DEVICE Russian patent published in 2015 - IPC B65D41/34 

FIELD: food industry.

SUBSTANCE: unit for closure of a bottle with liquid contains a closing device 1 and a bottle 2 neck equipped with a crown 3 with ring ribs on its lateral part with arresting ribs 4 designed with the preset pitch on the crown butt end. The closing device 1 contains a metal body 5 equipped with a ring section 22 with a slot between the upper and the lower interfacing edges 23 and 24, respectively, and with a ring flanging 25 with the help whereof a dispensing device 6 with an inner hollow is fixed inside the metal body 5. Additionally, the closing device 1 contains a plug 7 with an upper and a lower cylindrical seating surfaces 8 and 9, respectively, and with an upper and a lower supporting ring surfaces 10 and 11, respectively. The upper cylindrical seating surface 8 of the plug 7 is conjugated with the dispensing device 6 hollow surface; the plug lower cylindrical seating surface 11 contains a sealing 12 contacting with the bottle 2 neck; the lower supporting ring surface 11 of the plug 7 is equipped with fixing lugs 13 for prevention of the plug 7 spinning relative to the bottle 2 neck. The dispensing device 6 is equipped with a cylindrical skirt 14 containing fixing elements 15 for attachment to the crown 3 of the bottle neck 2; the upper supporting ring surface 10 of the plug 7 contains arresting elements 16 designed in the form of fixing teeth for prevention of the dispensing device 6 spinning relative to the plug 7 and is adjacent to the corresponding ring surface 17 designed in the dispensing device 6 hollow equipped with congruently positioned arresting elements 18 made in the dispensing device 6 hollow 6. Additionally, the closing device 1 contains a lid 26 with the thread on the inner surface interacting with the thread in the outer surface of the dispensing device 6 and screwed onto its upper part.

EFFECT: high reliability of bottle closure, revealing its unsanctioned opening, prevention of the closing device spinning relative to the bottle neck with simultaneous reduction of the device material intensity.
