FIELD: packing.
SUBSTANCE: proposed group of inventions relates to sealing devices for packing containers. Sealing device has mounting flange with flat upper and lower surfaces forming some thickness and plane of flange. Neck passes from upper surface of flange and it has inner wall forming discharge hole. Diaphragm has central section and round edge area, and it is formed in neck to pass to inner wall of neck, thus forming neck sealing. Diaphragm can be separated from neck in edge area. Edge area is made selectively thinned and is provided with pair of areas of first thickness and pair of areas of second thickness located between areas of first thickness. Thickness of second thickness areas exceeds thickness of first thickness areas.
EFFECT: provision of required hygienic standards owing to possibility of pasteurization and sterilization of product.
