[0037] Example

[0038] Reference Figure 1 to Figure 7 , is an embodiment of the utility model, and proposes

[0039] A detachable bottle cap comprises: a main body 1, the outer wall of the main body 1 having a spiral groove 2, a first cavity 3, and an open bottom; a barrel 4, the inner wall of the barrel 4 having a first protrusion 5, the first protrusion 5 being slidably arranged in the spiral groove 2, the barrel 4 having a plurality of through grooves 6, the plurality of through grooves 6 being used to communicate with the outside, the barrel 4 having a sealing end 7, the sealing end 7 being used to abut against the bottom of the main body 1, and after the first protrusion 5 rotates along the spiral groove 2, the first cavity 3 and the through groove 6 are connected or not connected.

[0040] The present embodiment provides a detachable bottle cap, which aims to solve the problem in the prior art that beverages are easily spoiled or their nutritional components are changed due to the short storage time after being prepared and packaged in a beverage bottle. The bottle cap is uniquely designed, with both the function of preventing accidental opening and the function of releasing ingredients on demand, ensuring that the beverage remains fresh before opening and extending the nutritional value within the validity period. The main body 1 is the main structure of the bottle cap, and its outer wall is provided with a spiral groove 2. A first cavity 3 is provided inside the main body 1 to accommodate the ingredients to be mixed. The bottom of the cavity is an open design to ensure that the ingredients can smoothly enter the bottle and mix with water under certain conditions. The barrel 4 is located inside the main body 1, and its inner wall is provided with a first protrusion 5, which is slidably matched with the spiral groove 2 on the outer wall of the main body 1. A plurality of through grooves 6 are provided on the barrel 4, and these through grooves 6 can be connected or isolated with the first cavity 3 when the relative position of the barrel 4 and the main body 1 changes. The bottom of the cylinder 4 is provided with a sealing end 7. When the cylinder 4 is completely docked with the main body 1, the sealing end 7 is in close contact with the bottom of the main body 1 to form a closed state to prevent the ingredients from leaking in advance. In the initial state, the position of the first protrusion 5 of the cylinder 4 along the spiral groove 2 of the main body 1 makes the first cavity 3 and the through groove 6 in a disconnected state, and the internal ingredients are effectively isolated to avoid contact with the water in the bottle in advance, so as to maintain their activity and stability. At this time, the bottle cap as a whole is in an anti-misopening state. Due to the specific locking structure between the cylinder 4 and the main body 1, the bottle cap cannot be easily opened by abnormal operation, ensuring that it will not be accidentally opened during transportation and storage. When the consumer is ready to drink, the first protrusion 5 of the cylinder 4 is rotated to a specific position along the spiral groove 2 through specific operating steps. At this time, the first cavity 3 is connected with the through groove 6, and the internal ingredients can be evenly released into the bottle through the through groove 6 and mixed with water to form a preset drink. This on-demand release method ensures that the ingredients are in contact with water at the moment of opening, which maximizes the survival period of its effective ingredients and reduces the dependence on additives such as preservatives. In summary, the detachable bottle cap provided in this embodiment realizes the delayed release of ingredients through the ingenious structural design of the main body 1 and the barrel 4, effectively solving the problem of short storage time and easy deterioration of beverages after packaging in the prior art. At the same time, the bottle cap has the function of preventing accidental opening, which increases the safety of product use, and is particularly suitable for the packaging of healthy drinks containing easily inactivated ingredients, thereby improving consumers' satisfaction and trust in the product.

[0041] Furthermore, the main body 1 has a first slot 8, which is connected to the spiral slot 2, and the first slot 8 is perpendicular to the axial direction of the main body 1. The outer wall of the main body 1 has a plurality of first slide grooves 9, which are connected to the first slot 8. The first protrusion 5 has a first guide slope 10, and also includes: a slider 11, which has a plurality of sliders 11, which are respectively and one by one slidably arranged in the first slide groove 9, and the slider 11 has a second guide slope 12. After the first guide slope 10 and the second guide slope 12 abut, they are used to push the slider 11 to slide along the first slide groove 9; an elastic member 13, which has a plurality of elastic members 13, each of which has one end arranged on the main body 1 and the other end arranged on the slider 11, and is used to provide a force for the slider 11 to approach the first slot 8.

[0042] This embodiment further describes in detail the locking and unlocking mechanism between the main body 1 and the barrel 4 in the detachable bottle cap, specifically involving the first card slot 8, the first slide slot 9, the first guide slope 10 on the main body 1, and the structure and matching relationship of the slider 11, the second guide slope 12, and the elastic member 13, so as to realize the precise control and anti-misopening function of the barrel 4. The outer wall of the main body 1 is provided with a spiral groove 2, which matches the internal thread 21 of the beverage bottle mouth to realize the threaded connection. The inside of the main body 1 is provided with a first cavity 3 for accommodating the ingredients to be mixed. The bottom of the main body 1 is provided with a first card slot 8, which is connected to the spiral slot 2 and is perpendicular to the axial direction of the main body 1. The outer wall of the main body 1 is also provided with a plurality of first slide slots 9, which are connected to the first card slot 8 to form a channel from the external operating area to the first card slot 8. The first guide slope 10 is provided on the first protrusion 5 inside the barrel 4. When the barrel 4 rotates with the bottle cap, the first guide slope 10 will move with the first protrusion 5 and participate in the locking and unlocking process between the barrel 4 and the main body 1. There are multiple sliders 11, and each slider 11 is slidably arranged in a first slide groove 9 of the main body 1. The slider 11 is provided with a second guide slope 12, which cooperates with the first guide slope 10 and is used to push the slider 11 to slide along the first slide groove 9 under specific conditions. There are also multiple sliders 11, and one end of each elastic member 13 is fixed to the main body 1, and the other end is connected to the corresponding slider 11. The elastic member 13 provides the slider 11 with a restoring force close to the first slot 8, ensuring that the slider 11 can be kept in a preset position in the non-unlocked state to prevent the cylinder 4 from rotating accidentally. Locked state: In the normal state, under the action of the elastic member 13, the back of the second guide slope 12 of the slider 11 is kept in contact with the back of the first guide slope 10 of the cylinder 4, preventing the cylinder 4 from rotating arbitrarily along the spiral groove 2. At this time, the first cavity 3 and the through groove 6 are still in a disconnected state, and the internal ingredients are effectively isolated. Unlocking operation: When the user performs a specific unlocking operation, the slider 11 is forced to overcome the resistance of the elastic member 13 and slides along the first slide groove 9 in a direction away from the first card slot 8, so that the first protrusion 5 and the slider 11 are not in contact. At this time, the first protrusion 5 of the barrel 4 can rotate freely along the spiral groove 2. The user continues to rotate the bottle cap, at which time the first cavity 3 is connected to the through groove 6, and the internal ingredients are released into the bottle. Reset: After drinking, the user rotates the bottle cap in the opposite direction, and the slider 11 is locked again under the action of the elastic member 13, and the barrel 4 returns to the initial locked state to prevent accidental opening and premature mixing of ingredients. In summary, this embodiment describes in detail the locking and unlocking mechanism composed of the first card slot 8, the first slide groove 9, the first guide slope 10, the slider 11, the second guide slope 12 and the elastic member 13 between the main body 1 and the barrel 4 in the detachable bottle cap. This mechanism ensures that in the non-unlocked state, the barrel 4 cannot rotate at will, effectively preventing the ingredients from mixing in advance and extending its active retention period. After the user performs a specific unlocking operation, the cylinder 4 can be accurately rotated to a predetermined position to achieve the on-demand release of the ingredients.The whole process is easy to operate and has good anti-misopening performance, which is suitable for the packaging of healthy drinks containing easily inactivated ingredients.

[0043] Furthermore, the cylinder 4 has a second slide groove 14 , and the slider 11 has a second protrusion 15 . The second protrusion 15 is used to be slidably arranged in the second slide groove 14 . After the second protrusion 15 slides, it drives the slider 11 to approach or move away from the first slot 8 .

[0044] This embodiment further describes in detail how to unlock the main body 1 and the barrel 4 in the detachable bottle cap. By manually pushing the second protrusion 15, the second protrusion 15 slides along the second slide groove 14 and squeezes the elastic member 13, so that the slider 11 moves away from the protrusion to complete the cancellation of the clamping.

[0045] Furthermore, the main body 1 has an opening 16, which is connected to the first cavity 3. The main body 1 has a plurality of second slots 17, and also includes: a cover body 18, which is hingedly arranged on the main body 1, and the cover body 18 has a plurality of third protrusions 19. The third protrusions 19 are used to slide into or out of the second slots 17. After the cover body 18 is rotated, it is used to open or close the opening 16.

[0046] The present embodiment further introduces the structure and matching relationship between the main body 1 and the cover body 18 in the detachable bottle cap, specifically involving the opening 16 on the main body 1, the second slot 17, and the third protrusion 19 on the cover body 18, indicating that the opening and closing of the opening 16 can be controlled by opening and closing the cover body 18, so as to achieve protection and convenient delivery of ingredients inside the first cavity 3.

[0047] Further, the barrel 4 includes: an outer barrel 20, a first protrusion 5 is located on the inner wall of the outer barrel 20, the main body 1 is rotatably arranged in the outer barrel 20, the outer barrel 20 has an internal thread 21, and the internal thread 21 is used to cooperate with the bottle body; an inner barrel 22, which is arranged on the outer barrel 20, the through groove 6 is located on the inner barrel 22, the outer barrel 20 and the inner barrel 22 form an installation gap 23, and the internal thread 21 is located at the installation gap 23.

[0048] This embodiment introduces in detail the split structural design of the barrel 4 in the detachable bottle cap, specifically involving the layout and matching relationship of the outer barrel 20, the inner barrel 22, the first protrusion 5, the internal thread 21 and the installation gap 23, and explains how the barrel 4 realizes the threaded connection with the bottle body and the ingredient release function through the combination of the inner and outer barrels 20. The outer barrel 20 is a part of the main body 1 of the barrel 4, and its inner wall is provided with a first protrusion 5, which cooperates with the spiral groove 2 of the main body 1 to control the rotation and locking of the barrel 4. The inner wall of the outer barrel 20 is a hollow structure for accommodating the inner barrel 22 and other components that cooperate with it. The outer wall of the outer barrel 20 is provided with an internal thread 21, which matches the external thread of the beverage bottle mouth to realize the threaded connection between the bottle cap and the bottle body. The inner barrel 22 is arranged inside the outer barrel 20, and is provided with through grooves 6, which are connected with the first cavity 3 when the barrel 4 is unlocked, allowing the ingredients to be released into the bottle through the through grooves 6. An installation gap 23 is formed between the inner tube 22 and the outer tube 20, and the internal thread 21 is located exactly in this gap, which neither hinders the threaded connection between the outer tube 20 and the bottle body nor protects the internal thread 21 from external wear or pollution.

[0049] Furthermore, the inner cylinder 22 has an annular groove 24 , which is located on the sealing end 7 , and the bottom of the main body 1 is used to slide into the annular groove 24 .

[0050] This embodiment further describes the matching relationship between the inner cylinder 22 and the bottom of the main body 1 in the detachable bottle cap, specifically the annular groove 24 on the inner cylinder 22 and how the bottom of the main body 1 can achieve accurate positioning and sealing matching with the inner cylinder 22 by sliding into the annular groove 24. The main body 1 of the detachable bottle cap is combined with the cylinder 4 to ensure that the first protrusion 5 is aligned with the spiral groove 2 of the main body 1. Subsequently, the assembled bottle cap is screwed onto the mouth of the beverage bottle, and the bottom of the main body 1 slides along the annular groove 24 of the inner cylinder 22 until it fits tightly with the sealing end 7 of the inner cylinder 22. At this time, the internal thread 21 of the outer cylinder 20 is meshed with the external thread of the bottle body to form a sealed connection, and the matching of the bottom of the main body 1 with the sealing end 7 of the inner cylinder 22 further enhances the overall sealing performance of the bottle cap.
