DETAILED DESCRIPTION

[0020] The embodiments of the present application will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0021] In the description of the utility model, it is necessary to explain that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0022] As Figure 1 , Figure 2 The utility model provides a kind of bottle mouth and bottle cap structure of beverage bottle, drinking water bottle, comprising, bottle mouth, upper cover body 1 and lower cover body 2.Upper cover body 1 and lower cover body 2 are flip cover type, and one side of upper cover body 1 and lower cover body 2 is connected by soft connection, such as flexible connecting band 3.In the center of lower cover body 2, cavity is provided, and the upper section 8 of bottle mouth is outwardly extruded after passing through lower cover body 2, and the lower section 9 of bottle mouth is left in lower cover body 2.

[0023] Further, annular bearing platform 4 is provided on the top of lower cover body 2, and the lower edge of upper cover body 1 is abutted on annular bearing platform 4 after the buckling of upper cover body 1 and lower cover body 2, so that the top surface edge of annular bearing platform 4 can be processed as stepped surface, so that the lower edge of upper cover body 1 is just abutted on stepped surface, which can prevent the deformation of the side wall of upper cover body 1 under stress, and can make the buckling of upper cover body and lower cover body more accurate.

[0024] Further, the utility model discloses that the inside of upper cover body 1 is a containing cavity, and annular sealing edge 6 is protruded downward from the top surface of the inner cavity of upper cover body 1, and the inner wall of sealing edge 6 is provided with protruding flange 13 for extruding and cooperating with the outer wall of the upper section of bottle mouth.When upper cover body 1 is buckled downward, flange 13 extrudes the outer wall of bottle mouth, so as to realize sealing.Further, sealing ring or sealing gasket 14 is arranged in the space surrounded by sealing edge 6 and the inner top surface of upper cover body 1, so as to further seal the outlet of bottle mouth after being tightly covered.

[0025] Further, the bottom end inner wall of the lower cover body is provided with a buckle 5, the outer wall of the lower section 9 of the bottle mouth is provided with a step surface 7 abutting against the annular abutment, and the buckle 5 is matched with a buckle ring 10 arranged below the step surface 7.
