[0005] By adopting the above scheme, the first limiting protrusion can be switched between the first grooves and the second grooves, so that the pressing part can be moved between different groove positions, thereby realizing the locking and unlocking functions of the pressing part.

[0006] Preferably, one end of each of the first grooves, the second grooves and the connecting openings is in communication with the top surface of the mounting cover, and the length of the second grooves is smaller than that of the first grooves.

[0007] By adopting the above scheme, the bottom end of the pressing part will be located at the top end of the mounting cover under the action of the first elastic member, so that the first limiting protrusion can be rotated at the position close to the end surface of the first grooves, the second grooves and the connecting openings; when the first limiting protrusion is moved in the first grooves, the pressing part can be extracted from the body with toothpaste; when the first limiting protrusion is moved in the second grooves, the second grooves limit the downward movement distance of the first limiting protrusion, so that the pressing part cannot be pressed to the bottom and the toothpaste cannot be extracted from the bottle body.

[0008] Preferably, the groove depths of the first grooves and the second grooves are both greater than the groove depth of the connecting openings.

[0009] By adopting the above scheme, the design of the groove depth makes the pressing piece more stable when moving, reducing the possibility of misoperation, and the connecting port is respectively on the side of the first groove and the second groove, so that the side limiting part of the first groove and the second groove is reduced, the first limiting protrusion can pass through the first groove or the second groove, and the mutual movement of the first groove and the second groove is not easy to occur in the daily use process.
