CONTAINER Russian patent published in 2013 - IPC B65D90/10 

FIELD: packaging industry.

SUBSTANCE: alleged invention relates to mechanical engineering and can be used to protect the interior of the container from entry of foreign objects, as well as sealing. Object of the alleged invention is to improve the reliability and safety of operation. The container comprises a housing with a flange, a cover and uniformly located locking devices. The cover is provided with a spring-loaded pressure element. Each locking device is made in the form of the cup housing, mounted on a side surface, with an axis parallel to the housing axis oriented with its end face to its flange. The cup is equipped with an insert mounted with the ability of axial movement inside the said cup. In the side surface of the cup there is a circular opening and a groove arranged in succession one after another from its end. The longitudinal axis of the groove is parallel to the cup axis and is located in a plane passing through the said cup axis and the housing axis. The insert is provided with a pin mounted in its first end and passing through the bottom of the cup asymmetrically to its axis, is arranged with the ability to interact with its first end with the cup bottom, is in contact with the second end with the compression spring mounted in the cup from the side of its end, is provided with two blind openings which are perpendicular to its axis and provided with compression springs, the sphere and the plunger for interaction with the circular opening and the groove of the cup, respectively. The insert is made with a cavity forming with its opening provided with a sphere for the edge for interaction on the side of the said opening with the said sphere at a point located on a circle with the diameter less than the diameter of the sphere. The sphere is made with a diameter greater than the width of the groove and the diameter of the circular opening of the cup and protrudes over its side surface. The plunger is made stepped, and the diameter of the larger step is equal to the diameter of the opening of the insert, and the step of a smaller one is provided with a spherical ending and is made with a diameter equal to the width of the groove of the cup. The cover is provided with longitudinal guides each of which is provided with a collar protruding over the end ledge made with the ability to interact with the inner edge with a sphere having a width less than the radius of the spherical end of the step of the plunger of smaller diameter, and having an opening for interaction with the step of the plunger of smaller diameter. The pressure element is provided with planks, at that each plank is made with the ability to interact with the end edge with the spherical end of the step of the plunger of smaller diameter, made protruding over the outer surface of the guide collar by amount not exceeding its radius at the closed position of the cover.

EFFECT: increased reliability and safety of operation.
