Beer easy bottle cap (00244080.6)
The beer easy-open bottle cap is changed from a single body of a traditional bottle cap into a composite of a cap portion and a ring portion, and two hidden steals are added on the back of the cap portion. The drop molding is changed from normal molding to super-thickness concave-convex surface molding to manufacture. The process has brought a lot of difficulties. This patent monitors the riveting point and the depth of the cuts, and solves a series of technical problems such as the positioning of the riveting points, the plastic drop, the pull ring cut, the pull ring and the lid connection.
