Field of the Invention [0002] The present invention relates to a pull-top ring which is bent into an L-shape which can easily cause the pull-top ring. 2. Description of the Related Art Conventionally, pull-top rings have been mainly used as drinking spouts for canned beverages, in which a finger is inserted between the ring and a narrow gap between the ring and the ring to cause the ring and simultaneously open the tab. [0003] This has the following disadvantages. The gap between the pull-top ring and the can was tight, and the fingertips required a lot of force to open the tabs, and the fingertips hurt, even though only a few fingertips could enter the narrow area. The present invention has been made to eliminate these disadvantages. [0004] The ring (1) of the pull-top is provided with a bending line (3) crossing the ring (1), and when the bending is performed from the bending line (3), the ring (1) becomes L A convex portion (4) for stopping in a letter shape is provided. The present invention is an L-shaped pull-top ring having the above configuration. [0005] Embodiments of the present invention will be described below. (B) There is a ring (1) for opening the tab (7) of the pull top. (B) The ring (1) is provided with a bending line (3) and a projection (4). (C) The bending line (3) is provided with a concave line or a perforation near the center of the surface of the ring (1) so that it can be easily bent and bends when the ring tip (2) is caused. However, it is not brittle enough to be easily cut. (D) The convex portion (4) is for the ring (1) to stop in an L-shape when the ring (1) is bent from the bending line (3), and is provided on the surface of the ring (1). The pair is provided so as to form a pair around the line (3). However, as long as the ring (1) stops in an L-shape, the number of protrusions (4) may be any number and may not be paired. (E) It is normal for the ring (1) to have a fold (5) toward the back side for safety and reinforcement,
In order to make it easier to bend than the fold line (3), the fold (5) on the extension of the fold line (3) is perforated or not. (F) L-shaped ring (1), but ring (1)
May be bent at a right angle like an L-shape, or may be formed at a shallower angle. The present invention has a structure as described above. When using this structure, when the ring tip (2) of the ring (1) is raised with a fingertip, the ring (1) is easily bent from the bending line (3), and is convex. The ring (1) is formed in an L-shape at the part (4). After the ring (1) has formed an L-shape, the ring (1) is easy to push with a finger, and when the ring (1) is pushed with a finger in the direction of the tab (7), the ring end (6) is turned into a tab ( 7)
To release. As described above, the tab (7) of the pull-top can be easily opened, and when used for a canned beverage, a can is easily formed in the can and a large force is applied to the fingertip. It does not require a finger and does not hurt your fingertips.
