When the puncturing member 140 abuts against the sealing membrane 131, in order to prevent the puncturing member 140 from puncturing the sealing membrane 131, the protection column 132 is arranged on the inner wall of the storage bin 130, and one end of the protection column 132 is flush with the opening of the storage bin 130, when the inner cover 120 and the outer cover 110 are assembled, the puncturing member 140 is aligned with the protection column 132, the protection column 132 cannot be deformed or the deformation is small, so that when the puncturing member 140 abuts against the sealing membrane 131, the protection column 132 can protect and support the sealing membrane 131 covering the protection column 132, and thus, when the sealing membrane 131 abuts against the puncturing member 140, the sealing membrane 131 cannot be greatly deformed, and when the sealing membrane 131 abuts against the puncturing member 140, the sealing membrane 131 cannot be punctured. When the outer cap 110 rotates relative to the inner cap 120, the puncturing member 140 is separated from the protection post 132 and abuts against the sealing film 131 without being supported by the protection post 132, thereby puncturing the sealing film 131.

In addition, one end of the puncturing part 141 facing the storage bin 130 exceeds the opening edge of the storage bin 130, so that the puncturing part 141 can puncture the sealing film 131 smoothly when the outer cover 110 rotates relative to the inner cover 120.

Referring to fig. 1 and 3, alternatively, a guide protrusion 127 is provided on the inner wall of the outer cover 110, a guide groove 1103 corresponding to the guide protrusion 127 is provided on the outer wall of the inner cover 120, and the piercing part 141 abuts against the guard post 132 by the guide groove 1103 and the guide protrusion 127.

As described above, when the inner lid 120 and the outer lid 110 are attached, the protection post 132 in the storage bin 130 is aligned with the puncture device 140 provided in the inner lid 120, and when the puncture device 140 abuts against the sealing film 131, the protection post 132 protects and supports the sealing film 131 covering the cross section of the protection post 132. Therefore, in order to align the protection post 132 with the puncture tool 140 in the process of mounting the inner cap 120 and the outer cap 110, the inner wall of the outer cap 110 is provided with the guide protrusion 127, and the outer wall of the inner cap 120 is provided with the guide groove 1103 corresponding to the guide protrusion 127, and when mounting the inner cap 120 and the outer cap 110, the guide protrusion 127 is first aligned with the guide groove 1103, and then the inner cap 120 and the outer cap 110 are mounted.

Referring to fig. 3 to 5, when the bottle body is fixedly connected to the bottle cap 100, the puncturing member 140 provided on the inner cap 120 is moved relative to the sealing film 131 by rotating the outer cap 110 relative to the inner cap 120, and then the puncturing member 140 punctures the sealing film 131 during sliding relative to the sealing film 131, and then the bottle cap 100 is rotated in the opposite direction to separate the bottle cap 100 from the bottle body, so that when the outer cap 110 is rotated relative to the inner cap 120, the bottle cap 100 is fixedly connected to the bottle body, and when the outer cap 110 is rotated in the opposite direction, the outer cap 110 and the inner cap 120 are rotated together, so that the inner cap 120 can be rotated relative to the bottle body, that is, the inner cap 120 and the outer cap 110 can be rotated in only one direction, for this purpose. Optionally, a non-return protrusion 126 is disposed on a side of an outer wall of the inner annular surface 121 facing away from the cavity 124, a non-return groove 1102 corresponding to the non-return protrusion 126 is disposed at a bottom of the outer cover 110, and the outer cover 110 can rotate in one direction relative to the inner cover 120 by cooperation of the non-return protrusion 126 and the non-return groove 1102.

Illustratively, when the outer cap body 110 rotates clockwise, the outer cap body 110 rotates relative to the inner cap body 120, the check protrusion 126 moves relatively in the check groove 1102, and when the outer cap body 110 rotates counterclockwise, the check protrusion 126 is caught in the check groove 1102, so that the check protrusion 126 cannot move relatively in the check groove 1102, and therefore, at this time, the outer cap body 110 and the inner cap body 120 rotate counterclockwise simultaneously, so that the bottle cap 100 rotates relative to the bottle body, thereby removing the bottle cap 100 from the bottle body.

In order to further enhance the rotation effect of the outer cover 110 with respect to the inner cover 120 in one direction and the cooperation effect of the check projection 126 and the check groove 1102, optionally, the check projection 126 extends in a direction away from the center of the inner cover 120.

Referring to fig. 2, optionally, a clamping ring 1223 is further disposed on an inner wall of the outer cover 110, and a clamping groove 1101 corresponding to the clamping ring 1223 is disposed on the outer annular surface 122, or the clamping ring 1223 is disposed on the outer annular surface 122, and the clamping groove 1101 corresponding to the clamping ring 1223 is disposed on the inner wall of the outer cover 110, so that the outer cover 110 and the inner cover 120 are fixedly connected through the matching of the clamping ring 1223 and the clamping groove 1101.

It should be noted that the width of the snap ring 1223 is slightly smaller than the width of the snap groove 1101, so that the outer cover 110 can rotate smoothly relative to the inner cover 120. The height of the clamping ring 1223 corresponds to the depth of the clamping groove 1101, and the clamping ring is appropriately sized so that the inner cover body 120 can be smoothly installed into the outer cover body 110.
