DETAILED DESCRIPTION

[0020] In the description of the utility model, it is necessary to understand that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is the orientation or positional relationship shown based on the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element indicated 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" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features limited by "first", "second" and the like can explicitly or implicitly include one or more of the features.

[0021] In the description of the utility model, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0022] In the description of the utility model, it should be noted that, unless otherwise expressly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0023] A bottle cap with independent storage bin, comprising upper cover 1, lower cover 2 and storage bin 3, the upper cover 1 comprises side wall 4 and inner cylinder 5, the side wall 4 is provided with internal thread 6, the bottom of the side wall 4 is provided with a tear ring 7, which can prevent accidental misuse, the inner cylinder 5 is provided with a plurality of vertical distribution of the partition 8, the lower cover 2 comprises upper side wall 9, lower side wall 10 and outer side wall 11, the upper side wall 9 is provided with external thread 12, the external thread 12 of the upper side wall 9 is engaged with the internal thread 6 of the upper cover 1 side wall 4, the outer side wall 11 is provided with internal thread 6, the outer side wall 11 is provided with anti-theft ring 19, the lower side wall 10 is provided with internal thread 6, the lower side wall 10 is provided with a sharp part 13, the storage bin 3 is a bottom opening cylinder, the bottom of the storage bin 3 is provided with a sealing film 20, the top of the storage bin 3 is vertically provided with a plurality of vertical strip 14, the storage bin 3 is provided with external thread 12, the external thread 12 of the storage bin 3 is engaged with the internal thread 6 of the lower side wall 10, the external thread 12 of the storage bin 3 is opposite to the external thread 12 of the upper side wall 9, the sharp part 13 is separated from the lower side wall 10, the lower side wall 10 is provided with a clamping groove 17 or a clamping table, the sharp part 13 is provided with a clamping block 18, the clamping block 18 can be matched with the clamping groove 17 or the clamping table, the sharp part 13 comprises a connecting strip 15 and a circular ring 16, the connecting strip 15 and the circular ring 16 are located in the clamping block 18, the circular ring 16 is provided with a plurality of sharp protrusions 21, the sharp protrusions 21 are vertically upward, the sharp protrusions 21 can be triangular or the inclined surface cut formed by lengthening one side of the circular ring 16.
