FIELD: packaging industry.SUBSTANCE: container is made of corrosion-resistant metal and comprises a housing (1) with a flange (2) rigidly connected to the upper edge of the container, of round or square cross-section, a cover (3) which is pivotally connected to the flange (2), and easily deformable gasket (4) between the cover (3) and the housing (1). The cover (3) is attached to the housing (1) hingedly on the loop which with one of its leaf (6) is rigidly fixed to the lower part of the cover (3) at the level of the gasket (4). The thickness of the leaf (6) is less than the thickness of the gasket (4). Another leaf (7) of the loop is rigidly connected from outside of the flange (2) cut of the housing obliquely to the horizon. The axis (8) of the loop faces outwards. On the cover (3) the cut of the upper edge is made at the same angle as on the flange (2) but in the opposite direction. On the cover (3) the L-shaped handle (9) is rigidly mounted diametrically opposed to the loop with horizontal shelf downwards, with the ability to set fingers between the flange (2) of the housing and the shelf of the handle. The cover (3) is provided in the area of the handle close to the center with the captive controlling bolt (10). From below on the housing (1) on the same vertical with the loop (5) the spring-loaded lock (11) is rigidly mounted. The rod (12) of the lock is provided with the L-shaped handle (13). On the cover (3) from the inner side at a distance from the edge an annular groove is made. The gasket (4) has a cutout for a loop, a hole for the captive controlling bolt and three windows with rounded ends made symmetrical and equally spaced and matching when installing with the annular groove of the cover (3). From below of the flange (2) of the housing (1) a valve (18) is mounted which enables to pump out or pump in the air into the area of the annular groove.EFFECT: maintaining the quality of fodder.4 dwgИзобретение относится к сельскому хозяйству и может быть исполь
