FIELD: machine building.
SUBSTANCE: valve (100, 200, 300) includes material with surface (114, 214) of the first side and surface (116, 216) of the second side, which limit thickness of material, determined between them. Material comprises at least two self-sealing slits (126, 130, 226, 230) extending over the entire thickness and comprising at least one destructible portion (150, 250), extending in lateral direction between at least two slits (126, 130, 226, 230) over at least a portion of said thickness of material. Material comprises opposite openable parts along at least two slots (126, 130, 226, 230) to form a normally closed hole to minimize communication through valve (100, 200, 300). Opening parts are retained by at least one breakable part (150, 250) from displacement from each other into an open position.
EFFECT: group of inventions relates to valves for use in a fluid container.
