AN EASY OPEN CROWN CAP AND ITS PRODUCTION METHOD
The present invention discloses an easy open crown cap and its production method. It is composed of a top and a side, and a connecting strip with a handle is extended from the hemline on its side. The first longitudinal incision and the second longitudinal incision are symmetrically established on both sides of the said connecting strip on its side. The said first incision and second incision are located between its top and the hemline on its side. An easy open crown cap and its production method in the present invention use such a manner that the crown cap can be easily opened, which can avoid bruising the bottle mouth when it is opened, and improve the recycling rate of glass bottles. Due to the existence of incisions on the side of the cap, when the pressure sealed within a glass bottle is overhigh because of external factors, the incisions on the side of the cap will be swelling up, which results in air leak, reduces the risks of glass bottle explosion after sealing, can avoid the phenomenon of twisted insertion between crown caps caused by existing incisions during production in a production line, guarantee the product quality and enhance the productivity effect.
