Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Example 1

Referring to fig. 3 to 4, the anti-slip tab structure includes a tab 100, wherein a recessed area 110 is provided on the tab 100, and the recessed area 110 is used for being fixedly connected with a pop-top lid; the recessed area 110 is formed by inwards recessed from the front side of the pull ring 100, a through hole is formed in the middle of the recessed area 110, the front side of the recessed area 110 is fixedly connected with the rivet 200, the back side of the recessed area 110 is used for abutting against the easy-open cover, grooves 111 distributed around the through hole are formed in the back side of the recessed area 110, and frictional resistance is generated after the grooves 111 abut against the easy-open cover.

The reverse side of said recessed area 110 comprises an annular plane for abutment with the lid, said grooves 111 being arranged centrally symmetrically on said annular plane. The arrangement of the groove 111 on the plane of the ring shape toward the center of the ring shape may enable the groove 111 to generate frictional resistance in all directions, thus effectively preventing the tab 100 from shaking.
