For example, the ready-to-drink bottle with Chinese application number: "202321450871.4", which includes a bottle cap body and a bottle body, the bottle cap body has a built-in ingredient bin, there is a gap between the outer wall of the ingredient bin and the inner wall of the bottle cap, and the surface of the ingredient bin facing the bottle body is a breakable sealing layer; the bottle body includes a bottleneck, and the bottle cap body is connected to the bottle body via the bottleneck; a cone thorn assembly is movably provided on the inner wall of the bottleneck through a limiting member, the cone thorn assembly is located below the ingredient bin and is threadedly connected to the bottle cap body; the bottle cap body is closed on the bottle body, and under the limiting action of the limiting member, the cone thorn assembly can move toward the ingredient bin and pierce the sealing layer as the bottle cap body is rotated and opened, and the limiting member prevents the cone thorn assembly from moving down again as the bottle cap is buckled; the cone thorn member is one of a cone thorn needle or a cone thorn catheter.

[0003] However, the above structure has the following problems: after the sealing layer is punctured, the objects in the ingredient bin fall down and mix with the liquid in the bottle body, but cannot be mixed evenly. Usually, shaking is required to mix evenly. However, in the above structure, the bottle cap body is already in the process of being opened at this time, and the bottle body cannot be shaken, otherwise it is easy to cause liquid leakage. The bottle cap body must be screwed back and shaken again, and then the bottle cap body must be opened before drinking, which is a cumbersome step. Summary of the invention

[0004] The utility model aims to solve the above problems existing in the prior art and provide an instant dispensing bottle cap with simple steps and more reasonable operation.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a ready-to-use bottle cap, comprising an upper cover and a lower cover, the lower part of the lower cover comprising an inner shell and an outer shell, the inner wall of the outer shell being threadedly mounted on the bottle mouth so that the bottle mouth is located between the outer shell and the inner shell, a movable shell is movably arranged in the inner shell through a limiting mechanism, the upper cover is always sleeved on the upper part of the lower cover and can rotate relative to the lower cover, a storage shell is arranged in the upper cover, a sealing layer is arranged at the bottom of the storage shell, a storage bin is formed in the storage shell by the sealing layer, a cone thorn block is arranged on the movable shell, the top of the movable shell is threadedly connected with the bottom of the outer wall of the storage shell, the cone thorn block is located below the sealing layer, the upper cover is rotated, and under the limiting action of the limiting mechanism, the movable shell can move toward the sealing layer as the upper cover rotates, and the cone thorn block cuts the sealing layer; after the sealing layer is cut, the bottle mouth is still in a closed state, and at this time, the lower cover is rotated to open the bottle mouth.

DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 and Figure 2 As shown, the instant bottle cap comprises an upper cover 1 and a lower cover 2. The lower part of the lower cover 2 comprises an inner shell 21 and an outer shell 22, and the inner wall of the outer shell 22 is threadedly mounted on the bottle mouth 4 so that the bottle mouth 4 is located between the outer shell 22 and the inner shell 21. A movable shell 3 is movably arranged in the inner shell 21 through a limiting mechanism 5. The upper cover 1 is always sleeved on the upper part of the lower cover 2 and can rotate relative to the lower cover 2. A storage shell 11 is arranged in the upper cover 1, and a sealing layer 12 is arranged at the bottom of the storage shell 11. The sealing layer 12 forms a storage bin in the storage shell 11. A cone block 31 is arranged on the movable shell 3, and the top of the movable shell 3 is threadedly connected to the bottom of the outer wall of the storage shell 11, and the cone block 31 is located below the sealing layer 12. The upper cover 1 is rotated, and under the limiting action of the limiting mechanism 5, the movable shell 3 can move toward the sealing layer 12 as the upper cover 1 rotates, and the cone piercing block 31 cuts through the sealing layer 12; after the sealing layer 12 is cut, the bottle mouth 4 is still in a closed state, and the lower cover 2 is rotated at this time to open the bottle mouth 4.

[0018] In the above technical solution: the upper part of the lower cover 2 is provided with a first positioning ring 23, and the bottom of the first positioning ring 23 is a positioning step 24. The first positioning ring 23 is also provided with a first guiding slope 25. The inner wall of the upper cover 1 is provided with a second positioning ring 13, and the upper and lower surfaces of the second positioning ring 13 are respectively provided with a second guiding slope 14 and a third guiding slope 15. When the upper cover 1 is sleeved on the upper part of the lower cover 2, the second positioning ring 13 is located below the positioning step 24, and the positioning step 24 positions the upward movement of the second positioning ring 13 to prevent the upper cover 1 from accidentally detaching from the lower cover 2. The third guiding slope 15 and the first guiding slope 25 cooperate to guide the installation process of the upper cover 1, and the second guiding slope 14 guides the disassembly process of the upper cover 1 from the lower cover 2.

[0019] In the above technical solution: a limiting ring 16 is further provided in the upper cover 1 , and the limiting ring 16 is located outside the storage shell 11 . The upper part of the lower cover 2 is located between the inner wall of the upper cover 1 and the limiting ring 16 .

[0020] In the above technical solution: the limiting mechanism 5 includes a plurality of first limiting protrusions 51, a third limiting protrusion 53 located on the movable housing 3 and a plurality of second limiting protrusions 52 located on the inner wall of the inner housing 21. A limiting groove is formed between two adjacent second limiting protrusions 52, the first limiting protrusion 51 is located in the limiting groove, and the end faces of the third limiting protrusion 53 and the second limiting protrusion 52 are in contact. The first limiting protrusion 51 and the second limiting protrusion 52 limit the movement of the movable housing 3 in the longitudinal direction to prevent the movable housing 3 from rotating relative to the lower cover 2. The third limiting protrusion 53 positions the installation between the movable housing 3 and the inner housing 21. The end of the second limiting protrusion 52 is formed with a first contact inclined surface 54, and the third limiting protrusion 53 is formed with a second contact inclined surface 55, and the first contact inclined surface 54 and the second contact inclined surface are in contact. The bottom of the first limiting protrusion 51 is provided with a guide angle 56.

[0021] In the above technical solution: a cone thorn ring 32 is provided in the movable shell 3, and the bottom of the cone thorn ring 32 is connected to the movable shell 3 through a connecting block 33. The cone thorn block 31 is located at the top of the cone thorn ring 32, and the cone thorn block 31 is approximately triangular. The cone thorn block 31 corresponds to the edge of the sealing layer 12, and at the same time, during the slicing process, the sealing layer 12 rotates relative to the cone thorn block 31, that is, the cone thorn block 31 will eventually break an arc-shaped discharge port on the sealing layer 12, which greatly increases the area of ​​the discharge port, making the discharge speed of the storage bin faster and more thorough; and after the upper cover 1 has completed its rotation relative to the movable shell 3, the cone thorn block 31 completes the break, and at this time, a small part of the sealing layer 12 is still connected to the storage shell 11, preventing the sealing layer 12 from falling into the liquid in the bottle body, contaminating the liquid, and affecting drinking.

[0022] In the above technical solution: the bottom of the upper cover 1 and the lower cover 2 are both provided with an anti-theft ring 6. The anti-theft ring 6 and the upper cover 1 and the lower cover 2 are connected by a plurality of connecting bridges 61, so as to prevent the upper cover 1 and the lower cover 2 from loosening and causing leakage during transportation; in addition, whether the sealing layer 12 is broken and whether the storage bin has been unloaded can be judged by whether the anti-theft ring 6 and the connecting bridge 61 at the bottom of the upper cover 1 are broken; whether the anti-theft ring 6 and the connecting bridge 61 at the bottom of the lower cover 2 are broken can also be judged whether the bottle body has been opened, so as to ensure the hygiene and safety of the items in the bottle.

[0023] The upper cover 1 and the lower cover 2 in the instant bottle cap are no longer threadedly connected. When the upper cover 1 is rotated, the upper cover 1 only rotates without moving up and down. The cooperation of the positioning step 24 and the second positioning ring 13 prevents the upper cover 1 from accidentally separating from the lower cover 2. This arrangement ensures that the upper cover 1 will not open relative to the lower cover 2 during the process of cutting the sealing layer 12. At the same time, after the sealing layer 12 is cut, the bottle can be directly shaken without worrying about liquid leakage. When drinking, the lower cover 2 can be rotated to open the bottle mouth 4. The steps are simple and the operation is more reasonable. The cone thorn block 31 corresponds to the edge part of the sealing layer 12. At the same time, the sealing layer 12 rotates relative to the cone thorn block 31 during the cutting process, that is, the cone thorn block 31 will eventually break an arc on the sealing layer 12 The shaped feeding opening greatly increases the area of ​​the feeding opening, making the feeding speed of the storage bin faster and more thorough; and after the upper cover 1 is completely rotated relative to the movable shell 3, the cone thorn block 31 completes the break, and at this time, a small part of the sealing layer 12 is still connected to the storage shell 11, preventing the sealing layer 12 from falling into the liquid in the bottle body, contaminating the liquid and affecting drinking; the bottom of the upper cover 1 and the lower cover 2 are both provided with anti-theft rings 6, and whether the anti-theft ring 6 and the connecting bridge 61 at the bottom of the upper cover 1 are broken or not, it can be judged whether the sealing layer 12 is broken and whether the storage bin has been discharged; it can also be judged whether the bottle body has been opened by whether the anti-theft ring 6 and the connecting bridge 61 at the bottom of the lower cover 2 are broken or not, thereby ensuring the hygiene and safety of the items in the bottle.
