A recently granted patent (Publication Number: US11905073B2) discloses a unique cap design for can containers. The cap includes a cap body with a top plate portion and a skirt portion, along with a disk-shaped sealing member featuring a sliding layer and a protrusion portion that gradually decreases in thickness towards the outer edge. The sliding layer is separate from the cap body and faces the top plate portion, with a sealing layer on the opposite side. The outer diameter of the sealing layer matches or exceeds that of the sliding layer, ensuring a secure fit.

Moreover, the patent also covers a mold for manufacturing the cap, comprising a lower mold with a recess matching the cap body's shape, and upper molds for molding the sliding layer and sealing layer of the sealing member. The manufacturing method involves arranging the molded product in the lower mold, supplying resin materials, and molding them using the upper molds to create the sliding layer and sealing layer. The depth of the recess is crucial, equal to the sum of the top plate portion and sealing member thickness. This innovative design and manufacturing process aim to enhance the sealing capabilities of caps for can containers, ensuring freshness and preventing leaks effectively.
