Method of sealing food can

Abstract

Abstract PURPOSE: To prevent leakage or the like with a perfect sealing through mechanical integration of the food can body with contact surface of the cover means of an adhesive sealing material formed thereon. CONSTITUTION: A sealing material mixed with an adhesive substance such as silicon rubber or the like is spplied on the inner surface of a periphral rim of a cover 3 and then solidified dry. Otherwise, after the surface is coated with a sealing material 5, an adhesive agent is applied thereon and then, dried. The cover 3 is placed on the opening surface of the food can body 1 and then, with the rotation of a seaming roller 6, they are sealed together. At this point, the sealing material 5 is attached to the body 1 and grasped by a delay between the contact surface 4 of the cover 3 and a curled section of the opening surface 2 under the pressure. In this manner, the gap can be sealed evenly. COPYRIGHT: (C)1980,JPO&Japio
