COLD HARDENING CONTAINER Russian patent published in 2024 - IPC B24B31/06 

FIELD: packaging industry.

SUBSTANCE: invention relates to finishing and hardening treatment of parts in containers by surface plastic deformation. Cold-hardening container is made in the form of a metal box consisting of a body with a cover. Bottom of the housing is made in the form of inclined surfaces directed to the filling hole. Container comprises a gate mechanism made in the form of a housing with conical and cylindrical holes forming a cavity with a hollow conical rod located in it. Gate mechanism has a tight conjugation of the outer conical surface of the conical hollow rod with the inner conical surface of the body of the gate mechanism due to spring and nut fixed on end of conical hollow rod. Conical hollow rod has the possibility of rotation and position fixation in open and closed positions. In the open position, the cavity of the conical hollow rod is connected to the filling hole through the cylindrical hole of the housing, and in the closed position, the side surface of the conical rod forms an obstacle.

EFFECT: ruled out oil leakage, higher efficiency.
