Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a solid-liquid separation bottle cap that integrates a press-type sealing hopper bottom cover and a main cover body, such as... Figures 1-3 As shown, the device includes a main cap body 1, with a piercing body plug 4 installed at the bottom of the main cap body 1. A piercing body 3 is located at the bottom of the piercing body plug 4, and an easy-open sealing hopper bottom cover 12 is located below the piercing body 3. A hopper wall 5 is installed on the top outer side of the easy-open sealing hopper bottom cover 12, and a hopper is located on the inner side of the hopper wall 5. The piercing body plug 4 is specifically designed at the bottom of the main cap body 1, and the piercing body 3 at its bottom can accurately align with and pierce the easy-open sealing hopper bottom cover 12 below. This design not only simplifies the cap structure and reduces production costs, but also makes opening the hopper easier and more efficient through the direct action of the piercing body.

[0023] Meanwhile, the tight fit between the easy-open sealing hopper bottom cover 12 and the hopper wall 5 ensures the hopper's airtightness before opening, effectively preventing leakage of internal products or intrusion of external contaminants. When needed, the user can simply press the piercing body 3 through the bottom cover to quickly open the hopper, facilitating solid-liquid separation or controlling the product outflow.

[0024] In this embodiment, a bottle neck connecting sleeve 51 is connected to the outer side of the hopper wall 5. A bottle cap inner and outer seal 14 is installed on the upper inner wall of the bottle neck connecting sleeve 51, and a bottle cap thread 6 is provided on the lower inner wall of the bottle neck connecting sleeve 51. The bottle cap inner and outer seal 14 provides an additional sealing layer, effectively preventing leakage of liquid or gas and enhancing the sealing performance of the bottle cap. The bottle cap thread 6, through its threaded engagement with the bottle neck, securely fixes the bottle cap, preventing leakage or detachment due to loosening during use.

[0025] Specifically, the bottom of the bottle cap connecting sleeve 51 is connected to the bottle mouth via an anti-theft ring 8. This design not only enhances the connection strength between the bottle cap and the bottle mouth but also serves as an anti-theft measure. The anti-theft ring 8 will break or deform after the bottle cap is opened for the first time, making it impossible to close properly again, thus clearly indicating to consumers whether the bottle cap has been opened, ensuring product safety and protecting consumer rights.

[0026] Furthermore, a main cap body hopper welding molten adhesive groove 7 is provided at the bottom of the hopper wall 5, and a welding top position 10 is installed on the outside of the easy-open sealing hopper bottom cover 12. A bottom cover welding molten adhesive ring 9 is installed on the top of the welding top position 10. The main cap body hopper welding molten adhesive groove 7 and the bottom cover welding molten adhesive ring 9 are connected and fixed by ultrasonic welding. This technology ensures a firm connection between the bottom cover and the main cap body. As an efficient and environmentally friendly connection method, ultrasonic welding not only improves production efficiency but also avoids the leakage risks that may be caused by traditional connection methods, further enhancing the sealing performance and overall strength of the bottle cap.

[0027] Furthermore, the surface of the easy-opening sealing hopper bottom cover 12 is provided with several easy-opening lines 11, and a sealing hopper bottom piercing position 13 is provided in the middle of the easy-opening sealing hopper bottom cover 12. This provides users with a convenient opening method. The easy-opening lines 11 allow the bottom cover to crack along a predetermined trajectory when subjected to external force, while the piercing position 13 ensures that the piercing body 3 can accurately and easily penetrate the bottom cover, realizing the rapid opening of the hopper. This design not only ensures the sealing of the bottom cover before opening but also improves the user's ease of use.

[0028] Furthermore, a resilient pressing cap 2 is installed on the outer side of the main cap body 1, and the outer side of the resilient pressing cap 2 is connected and fixed to the inner wall of the hopper wall 5. This provides users with a comfortable pressing experience. The resilient pressing cap 2 can not only evenly distribute the pressure during pressing, but also quickly return to its original shape after pressing, ensuring the long-term use effect of the bottle cap. At the same time, this design also increases the aesthetics and feel of the bottle cap.

[0029] Furthermore, a locking lever 32 is installed at the top of the piercing body 3, and a conical end 31 is installed at the bottom of the piercing body 3. Together, they constitute the core structure of the piercing body. The locking lever 32 ensures that the piercing body remains stably held within the snap-fit ​​container during pressing, preventing displacement or detachment. The conical end 31, with its sharp shape and gradually decreasing cross-sectional area, allows the piercing body to easily penetrate the bottom cap, achieving rapid and accurate opening of the hopper. This design ensures both the smoothness of the piercing process and improves the reliability of the bottle cap.

[0030] This utility model's press-type sealing hopper bottom cover and main cover body are integrated into a solid-liquid separation bottle cap. When not in use, the main cover body 1 and the easy-open sealing hopper bottom cover 12 are tightly connected using ultrasonic welding technology, ensuring the hopper's airtightness. The bottle mouth connecting sleeve 51 is firmly fixed to the bottle mouth by the bottle cap threads 6, while the inner and outer seals 14 of the bottle cap provide an additional sealing layer, effectively preventing liquid or gas leakage. The anti-theft ring 8 breaks or deforms after the bottle cap is first opened, serving both anti-theft and indication functions of whether the bottle cap has been opened.

[0031] When the user needs to use the product, pressing the elastic pressing cap 2 transmits pressure to the piercing body 3 inside the main cap 1. Guided by the locking lever 32, the piercing body 3 is stably held within the piercing body buckle 4, preventing displacement or detachment. At the same time, the tapered end 31 at the bottom of the piercing body 3, due to its sharp shape and gradually decreasing cross-sectional area, can easily penetrate the sealing piercing position 13 on the easy-open sealing hopper bottom cover 12.

[0032] As the piercing body 3 penetrates, the easy-open sealing hopper bottom cover 12 cracks along the preset easy-opening line 11, and the hopper is opened quickly and accurately. At this time, the user can easily perform solid-liquid separation or control the outflow of products through the opened hopper.

[0033] Throughout use, the elastic press-fit cap 2 not only provides a comfortable pressing experience but also evenly distributes the pressure during pressing and quickly returns to its original shape after pressing, ensuring the long-term effectiveness of the cap. Meanwhile, the ultrasonic welding connection between the main cap's hopper welding melt tank 7 and the bottom cap's welding melt ring 9 ensures a strong bond between the bottom cap and the main cap, further enhancing the cap's sealing performance and overall strength.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
