In a preferred embodiment, the groove may be an integral annular groove or may be a plurality of grooves uniformly distributed along the annular groove. The protruding portion is matched with the groove. Fig. 5-7 show an annular groove.

In a preferred embodiment, as shown in fig. 8-10, a connection 240 may be provided between the upper portion 201 and the lower portion 202 of the second layer 200. The tear structure 231 may be approximately annular, and together with the connecting portion 240, forms a complete ring shape. The connecting portion 240 may be flexible so that when the tear structure 231 is torn off, the upper portion 201 and the lower portion 202 remain connected by the connecting portion 240 and can be flipped about for opening or closing action.

In a preferred embodiment, a connection 240 may be provided between the upper portion 201 and the lower portion 202 of the second layer 200. The upper portion 201 and the lower portion 202 of the second layer 200 are rotatably connected by the connecting portion 240. The tear structure 231 may be approximately annular, and together with the connecting portion 240, forms a complete ring shape. After the tear structure 231 is torn off, the upper portion 201 and the lower portion 202 are kept connected by the connecting portion 240 and can be turned around for opening or closing.

In a preferred embodiment, as shown in fig. 2 and 3, the tear structure 231 may include a pull portion 232.

In a preferred embodiment, as shown in fig. 1-9, the opening and closing structure 203 may be a raised brim disposed on the upper portion 201 of the second layer 200, or may be in the form of a tab as shown in fig. 10.

In a preferred embodiment, as shown in fig. 1 and 2, the bottle cap may further include a third layer 300, the third layer 300 being disposed on the second layer 200; the second layer 200 has an opening 211 in the center of the upper surface 210, and the third layer 300 seals the opening 211.

In a preferred embodiment, the first layer 100 may be made of a rubber material, the second layer 200 may be made of a metal material, and the third layer 300 may be made of a plastic material.
