Description of the invention () Technical field (please read the precautions on the back before filling this page) This invention relates to the top cover structure of the material tank, which has an open-and-open (otte_touch) or a stay-type pull ring (stay- On tab) can opening device is used to open the can, especially a kind of can cover structure. The outer end of the pull ring can be lifted off the surface of the can by the finger pressing action. It is mainly used to form a gap between the split ring and the top cover before the opening piece is pulled up, so that the top lid opening piece can open the hopper. The opening piece is provided with a finger pushing part, an elastic protrusion controlled by a thumb and / or a groove provided at a predetermined position, so that the user can easily pull up the opening piece to leave the top cover upward to open the hopper. Hygienic conditions, ease of operation and reliability of operation. As shown in Figure 1, the back cover technology is provided with a pull ring 30 on the lid of the various types of conventional tanks for opening the opening 22 of the tank 10 along the seam. For example, the traditional pull ring is set to be pulled upward. An opening piece is raised to open the seal formed by the opening piece, and until the opening piece completely leaves the top cover, an opening can be formed in the top cover. The other type of pull-up ring is set up to open the top of the hopper by the opening piece, and the opening piece is completely opened by 1½ years. Another type of push-in pull ring can make the pull ring push the opening piece into the inside of the tank when it is pulled up, and the seal of the opening piece can be opened along the crimping seam for the top cover to form an opening. In addition, the Intellectual Property Bureau of the Ministry of Economic Affairs and the Consumer Consumption Cooperative of Indonesia. In addition, the combined split pull ring is set up to open the seal along the seam and press the split piece into the tank. It is also widely used in the existing technology. . This type of material tank opening pull ring 30 is generally made of steel or aluminum. In order to open the top cover before use, the pull ring 30 positioned on the top surface 20 of the top cover with rivets 24 can be pulled up along the pressure seam 21 to The opening of the opening sheet is opened for forming a desired opening on the top cover of the tank body. The user thus emptyes the inside of the spout tank through the opening. Page 1 of 10 This paper applies the national standard of the country (&^; 5), 4 specifications (210 fathers, 297 males), A7 B7 46 92 5 V. Description of the invention () In short, this traditional tin can is The tank is tightly pressed or vacuum-sealed, so the tank body is susceptible to water hammering action. The high-pressure internal liquid in the tank will be pressurized to the top of the spout tank when it is subjected to an unexpected external impact pressure on the beverage tank. In this water hammering action, the shear stress will act on the opening piece 22 which is confined to the top cover of the tank with the concave pressure seam 21, and may be opened along the pressure seam 21 under unexpected conditions and closed. Office. Therefore, the seam 21 must have sufficient strength to resist the shear stress caused by the water hammer action. In order to open the opening piece 22 along the pressure seam 21 for forming an opening in the can lid, the user must apply a sufficient force to the opening piece 22 by the pull ring 30 to open the opening piece 22 along the pressure seam 21. Since the pull ring 30 and the opening piece 22 are engaged with each other, the end portion 31 of the pull ring 30 is the initial opening force when the user pulls it up. However, when the end portion 31 of the pull ring 30 is pulled up from the upper surface 20 of the can lid, it is quite difficult. This necessary opening force often forces some children or elderly users to ask someone to help them open the can. In addition, because the pull ring is set close to the lid, so that there is no proper distance between the pull ring and the lid, the user must insert a sheet of material such as fingernails before reaching the end 31 of the pull ring and Between the can lids, the end portion 31 is lifted off the upper surface 20 of the can lid for levy, and the pull ring 30 is pulled up along the pressure seam 21 to open the seal of the opening piece 22. Such beverage cans are therefore inconvenient for users to open. That is, it is very difficult for the user to open the lid by pulling the pull ring with a finger, and sometimes the user ’s fingernails or fingers are injured. Another disadvantage of the traditional can lid is that the lid opening piece 22 may contaminate impurities. Such as dust, which makes the lid of the jar very unsatisfactory. SUMMARY OF THE INVENTION The object of the present invention is to improve the disadvantages of conventional technology, and provide a can lid structure which has a can opening device with enhanced can opening function and can improve sanitary conditions. Bounce the outer end of the pull ring, which is mainly to form a proper distance between the pull ring and the tank lid before the pull ring pulls the opening sheet open. The pull ring also has a finger pushing part, and a thumb finger controls the elastic protrusion. And / or the grooved part located at the predetermined position, use page 2 of 10 pages.
