Description

[Technical Field]

[0001] This utility model relates to a rotary pull-type bottle cap separating device. [Background Technology]

[0002] Separable bottle caps are a common type of bottle cap in daily life. They use a physical structure to store solids or liquids separately from the liquid inside the beverage bottle. When people need to drink the liquid in the bottle, the solids or liquids sealed inside the cap are released into the bottle to mix. This preserves the freshness of the ingredients and enhances the drinking experience. This design is not only hygienic but also extends the shelf life.

[0003] Currently, most detachable bottle caps on the market, as disclosed in Chinese Utility Model Patent No. CN219155230U, include an outer cap threaded to the bottle opening and an inner cap that fits over the outer cap. The outer cap forms a material receiving cavity that extends perpendicularly to the end face of the outer cap into the bottle opening. The inner cap has a discharge connecting cavity for releasing raw materials and sealing the material receiving cavity. When the inner cap and outer cap are fitted together, the discharge connecting cavity connects to the material receiving cavity, sealing its opening. When the outer cap and inner cap separate, the sealed material in the material sealing cavity falls into the bottle, resulting in a mixed beverage. However, during transportation, these detachable bottle caps are prone to accidental rotation due to vibration or impact, causing the outer cap to rotate relative to the bottle opening, leading to the inner cap separating from the outer cap and resulting in material leakage, affecting product safety and user experience.

[0004] Therefore, this utility model was created based on the above-mentioned shortcomings. [Utility Model Content]

When the follower part 4 enters the unlocking hole 32 from the horizontal rotation hole 31, the movable storage body 2 can be pulled up relative to the bottle cap body 1 to move upward so that the connecting port 22 communicates with the connecting cavity 11.

[0009] The rotary bottle cap separating device described above is characterized in that: the follower part 4 is provided on the outer side wall of the movable storage body 2, the horizontal rotating hole 31 extends circumferentially along the side wall of the bottle cap body 1, and the unlocking hole 32 extends vertically along the side wall of the bottle cap body 1.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1.

Detailed Implementation Methods

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1 to 7 As shown, a rotary pull-type bottle cap separating device includes a bottle cap body 1 that can be installed on the bottle mouth. The bottle cap body 1 has a connecting cavity 11 and a discharge port 12 communicating with the connecting cavity 11. The connecting cavity 11 has a movable storage body 2 that can be movably arranged relative to the bottle cap body 1 and has one end extending out of the connecting cavity 11 for manual operation. The movable storage body 2 has a storage cavity 21 for storing raw materials to be mixed and a connecting port 22 communicating with the storage cavity 21. One of the bottle cap body 1 and the movable storage body 2 has a guide hole 3, and the other has a follower part 4 that extends into the guide hole 3 and moves along the guide hole 3 when the movable storage body 2 is manually driven. The guide hole 3 has a positioning structure 5 that can block the follower part 4 during its movement. When the follower part 4 squeezes past the positioning structure 5 and moves to the end of the guide hole 3, the connecting port 22 communicates with the connecting cavity 11, allowing the raw materials to be mixed to be discharged from the discharge port 12. This device effectively buffers vibrations caused by transportation or collisions by using the positioning structure 5 to block the follower part 4, preventing accidental rotation or lifting of the moving storage body, ensuring the sealing and isolation of the connecting port and the connecting cavity in the initial state, and preventing raw material leakage.

[0031] Furthermore, the guide hole 3 includes a horizontal rotation hole 31 for the follower part 4 to slide within when the movable storage body 2 is manually rotated relative to the bottle cap body 1, and an unlocking hole 32 located at the end of the horizontal rotation hole 31 and communicating with it. When the follower part 4 enters the unlocking hole 32 from the horizontal rotation hole 31, the movable storage body 2 can be pulled upward relative to the bottle cap body 1, so that the connecting port 22 communicates with the connecting cavity 11. The user must first rotate the movable storage body 2 so that the follower part 4 overcomes the locking resistance of the positioning structure 5 and moves to the end of the guide hole 3 before the lifting operation can be performed. This double safety mechanism of rotating before lifting effectively avoids accidental rotation opening caused by vibration or collision during transportation and handling, fundamentally solving the leakage problem.

[0032] Specifically, the follower part 4 is located on the outer wall of the movable storage body 2. The horizontal rotation hole 31 extends circumferentially along the side wall of the bottle cap body 1, and the unlocking hole 32 extends vertically along the side wall of the bottle cap body 1. Thus, the guide hole 3 formed by the horizontal rotation hole 31 and the unlocking hole 32 is L-shaped. In a specific implementation, two follower parts 4 are provided, one on each side of the movable storage body 2, and two guide holes 3 are also provided, one on each side of the bottle cap body 1.

[0033] To prevent the bottle cap 1 from rotating relative to the bottle body when the movable storage body 2 is rotated, the inner wall of the bottle cap 1 is provided with a bottle cap thread 13 that matches the external thread of the bottle mouth. The extension direction of the horizontal rotation hole 31 is the same as the helical direction of the bottle cap thread 13. In this way, the rotation direction of the movable storage body is consistent with the bottle cap locking direction, thus preventing the bottle cap 1 from rotating relative to the bottle body and opening when the movable storage body 2 is rotated.

[0034] like Figure 1 As shown, the positioning structure 5 includes a first positioning tooth 51 disposed within the horizontal rotation hole 31 and initially located between the follower part 4 and the unlocking hole 32, and a second positioning tooth 52 disposed within the unlocking hole 32. The first positioning tooth 51 is disposed on the end of the horizontal rotation hole 31 away from the unlocking hole 32, and the second positioning tooth 52 is disposed on the end of the unlocking hole 32 away from the horizontal rotation hole 31.

[0035] Specifically, the first positioning protrusion 51 is an arc protrusion on the wall of the horizontal rotating hole 31. The second positioning protrusion 52 has two protrusions and is arranged opposite to each other on the wall of the unlocking hole 32. The two second positioning protrusions 52 have a pressing slope 521 that is inclined toward the middle of the unlocking hole 32 and the inclination direction is toward the end of the unlocking hole 32, so that when the follower is pulled up, it can smoothly pass through the pressing slope, while preventing it from slipping in the opposite direction.

[0036] To facilitate the assembly of the movable storage body and the bottle cap body, the follower part 4 is a cylindrical protrusion. The upper end of the connecting cavity 11 is open for the lower end of the movable storage body 2 to be inserted. The inner wall of the bottle cap body 1 is provided with a guide groove 14 that guides the cylindrical protrusion from the opening to the horizontal rotating hole 31 when the lower end of the movable storage body 2 is inserted into the connecting cavity 11. When the lower end of the movable storage body is inserted into the connecting cavity, the guide groove can guide the cylindrical protrusion from the opening to the horizontal rotating hole, completing the initial assembly positioning and improving production efficiency.

[0037] To meet the initial sealing requirements, the connecting port 22 is located at the bottom of the movable storage body 2. The inner bottom wall of the bottle cap body 1 is provided with a sealing boss 15 that is inserted into the connecting port 22 to seal the connecting port 22. In the initial state, the sealing boss is inserted into the connecting port to isolate the storage cavity from the connecting cavity. Multiple discharge ports 12 are provided around the bottle cap body 1 and are located on the bottom of the side wall of the bottle cap body 1. The discharge ports 12 that are evenly distributed on the bottom of the side wall of the bottle cap body can ensure that the raw materials can smoothly enter the bottle.

[0038] In addition, the end of the movable storage body 2 extending out of the cap body 1 is provided with a cap opening 23 that communicates with the storage chamber 21. A top cap 6 is threadedly connected to the cap opening 23 to cover it. When in use, the user can directly unscrew the cap, and the mixed beverage can flow from the beverage bottle through the outlet 12, the communicating chamber 11, the storage chamber 21, and then out of the cap opening 23 for direct consumption. There is no need to unscrew the entire device, making it convenient to use, in line with the usage habits of the general public, hygienic and environmentally friendly, and also conducive to recycling.

[0039] In the initial state of this rotary bottle cap separating device, the connecting port 22 of the movable storage body 2 is blocked by the sealing boss 15 of the bottle cap body 1, and the raw material to be mixed in the storage cavity 21 cannot be released; the follower part 4 is located in the horizontal rotation hole 31 and is blocked by the first positioning protrusion 51, so it cannot move on its own; when it is necessary to mix the beverage, the user first rotates the top cover 6, which drives the movable storage body 2 to rotate relative to the bottle cap body 1. The follower part 4 slides within the horizontal rotation hole 31. When it slides to the first positioning protrusion 51, the user will feel obvious resistance and needs to apply a little force to make the follower part 4 squeeze and pass over the first positioning protrusion 51. After passing over the first positioning protrusion 51, the follower part 4 reaches the end of the horizontal rotation hole 31, which is also the entrance of the unlocking hole 32. At this time, the rotation action is completed. Then, the user pulls the top cover 6 and the movable storage body 2 upward, so that the follower part 4 enters from the horizontal rotation hole 31 and moves upward along the unlocking hole 32. When the follower part 4 passes the second positioning protrusion 52, it will feel resistance again and pass over it, and be positioned above the two second positioning protrusions 52. As the movable storage body 2 is lifted, its bottom connecting port 22 gradually separates from the sealing boss 15 of the bottle cap body 1. When the follower part 4 moves to the end of the unlocking hole 32, the connecting port 22 is completely connected to the connecting cavity 11 of the bottle cap body 1. The raw material to be mixed in the storage cavity 21 enters the connecting cavity 11 through the connecting port 22 under the action of gravity, and finally falls from the discharge port 12 into the bottle below to mix with the liquid in the bottle.
