COVER FOR RESERVOIR Russian patent published in 2006 - IPC B65D43/16 

FIELD: sealing facilities.

SUBSTANCE: proposed cover for reservoir contains main housing 31 and gate with hinged part 62 hinge-connected with pressure part 61. Pressure part is hinge-connected with main housing. Main housing has cavity 34 with support wall 40 serving as border. Hinged part is arranged to engage with support wall and turn relative to pressure part in response to pressing downwards onto pressure part. To control opening of gate in at least two positions, lock mechanism is used. In first position, lock mechanism provides reliable fixing of pressure part in closed position, and in second position, it provides reliable locking of pressure part in open position. According to one of design versions, bottom 44 of cavity is made tilted, thanks to which useful volume of reservoir is increased and deflection of pressure part of gate is limited.

EFFECT: improved convenience of use of reservoir cover.
