SEALED CONTAINER FOR BULK MATERIALS Russian patent published in 2009 - IPC B65D53/00 

FIELD: packaging industry.

SUBSTANCE: sealed container for bulk material consists of a cylindrical body with bottom and neck, sealing and cover. The cylindrical body of sealed container is provided with guiding rims and ring-shaped platform on the upper end. The width of the above mentioned platform is defined from the conditions created for sealing when sealed container is pressed to the seating surface of receiving window in discharge unit. The neck of container is implemented with two tapered cones, which are rigidly connected along their small diametre by the ring of effective height. The removable sealing is placed in a groove in the point of cones connection. Besides the low cone is rigidly connected to the internal surfaces of vertical body wall and circular platform by its tapered surface but at an angle, which is equal or exceeding the angle of natural slope adherent to the stored material. The inner surface of upper cone has a threaded section. The cover is implemented in the form of hollow tapered cone with upper and perforated lower bases. There is a threaded cover section, which is available on the outer surfaces. The hollow tapered cone is rigidly and axially connected on the upper cover base of the cylindrical tail piece with the removable absorbing filter and safety valve. The cylindrical tail piece is implemented as a place for cover gripping by articulated arm. The lower base of cover is provided with bridge-breaking blade represented with a rod fixed to the edge of lower cover base, length and shape thereof is selected under condition of its effective operation.

EFFECT: invention allows for producing brand-new design of sealed container with improved conditions for bulk material transportation, storage and unloading.
