[0001] The utility model relates to the technical field of bottle caps, in particular to a solid-liquid separation bottle cap with a bottom sealing and an inner opening. Background Art

[0002] In the packaging industry, traditional bottle cap designs often struggle to meet the demands of both easy opening and a secure seal, particularly for products requiring solid-liquid separation, such as certain condiments, sauces, or medicines. Traditional solid-liquid separation caps typically require twisting, pulling, or other complex operations to open, which not only increases user complexity but can also cause liquid splashing or solid material scattering due to improper operation, impacting the user experience. Furthermore, traditional bottle caps have limitations in terms of sealing, making them prone to leakage after prolonged storage, leading to product deterioration or failure.

[0003] To address these issues, various improved solid-liquid separation bottle cap designs have gradually emerged on the market, but some shortcomings still exist. For example, while some bottle caps achieve solid-liquid separation, they are complex to open and inconvenient for users to use quickly. Other bottle caps, while easy to open, lack sealing properties and cannot effectively prevent product leakage. Therefore, there is an urgent need for a solid-liquid separation bottle cap that is both easy to open and has good sealing properties to meet market demand. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides a bottom-sealed, inner-opening solid-liquid separation bottle cap. Figure 1-Figure 3 As shown, it includes a lower flap cover 1, a lower piercing cover 10 is provided below the lower flap cover 1, a hopper 101 is provided in the middle of the inner side of the lower flap cover 1, the outer bottom of the lower flap cover 1 is connected to the lower piercing cover 10 by a tear-off breakpoint anti-theft ring 2, a hopper barrel wall 3 is installed inside the hopper 101, a water-sealing buckle 4 is installed on the outer wall of the hopper barrel wall 3, a lower inner opening sealing bottom 7 is installed at the bottom of the hopper barrel wall 3, and a lower piercing cover piercing cone 13 is installed in the middle of the lower piercing cover 10. When the lower flap cover 1 is pressed down, the lower inner opening sealing bottom 7 is driven to move downward, thereby causing the lower piercing cover piercing cone 13 to pierce the lower inner opening sealing bottom 7. The lower flap sealed bottom inner opening solid-liquid separation bottle cap provided by the utility model realizes an efficient and convenient solid-liquid separation function through its unique design structure. When the user presses down on the flap cap 1, this action cleverly drives the lower inner opening sealed bottom 7 to move downward, allowing the lower piercing cap piercing cone 13 to accurately pierce the lower inner opening sealed bottom 7. This innovative opening mechanism not only simplifies the user's operation process, making the bottle cap easy and fast to open, but also effectively avoids the problems of liquid splashing or solid material scattering caused by the complicated opening method of traditional solid-liquid separation bottle caps, greatly improving the user experience.

[0022] The design of this bottle cap also fully considers the importance of sealing. The tight fit between the silo wall 3 and the lower inner opening sealing bottom 7, as well as the provision of the water-sealing buckle 4, together form a reliable sealing system that effectively prevents leakage of liquid or solid materials inside the product during storage or transportation, thereby ensuring product quality and safety.

[0023] In this embodiment, an ultrasonic welding molten material trough 5 is provided at the bottom of the silo barrel wall 3, and a lower inner opening sealed bottom welding ring 6 is provided at the top side of the lower inner opening sealed bottom 7. The ultrasonic welding trough 5 and the lower inner opening sealed bottom welding ring 6 are sealed by ultrasonic welding. Ultrasonic welding technology achieves a tight and secure sealing connection. This welding method not only improves the sealing performance of the bottle cap, effectively preventing leakage of liquid or solid materials inside the product, but also enhances the overall structural strength of the bottle cap, making it more durable.

[0024] Specifically, a sealed bottom opening line 8 is provided in the middle of the lower inner opening sealed bottom 7, and a central top piercing opening position 9 is provided at the top of the sealed bottom opening line 8. This facilitates opening the bottle cap. The sealed bottom opening line 8 allows the lower inner opening sealed bottom 7 to more easily break along the predetermined line when pierced by the lower piercing cap piercing cone 13. The central top piercing opening position 9 ensures the accuracy and smoothness of the piercing process, further enhancing the user experience.

[0025] Furthermore, the outer side of the piercing cone 13 of the lower piercing cover is connected to the lower piercing cover water-sealing wall 12, which is then connected to the inner wall of the lower piercing cover 10. When the lower flap cover 1 is pressed downward, the silo barrel wall 3 and the lower piercing cover water-sealing wall 12 are sealed together, forming an additional sealing barrier. When the lower flap cover 1 is pressed downward, the silo barrel wall 3 and the lower piercing cover water-sealing wall 12 are sealed together, effectively preventing the splashing or scattering of liquid or solid materials during the opening process, ensuring the cleanliness and integrity of the product.

[0026] Furthermore, the inner wall of the lower piercing cap 10 is equipped with inner and outer seals 14 and bottle cap screw threads 15. This not only enhances the sealing performance of the bottle cap, but also allows the bottle cap to be securely screwed onto the bottle mouth, preventing leakage caused by loosening. The inner and outer seals 14 provide an additional sealing layer, while the bottle cap screw threads 15 ensure a tight fit between the bottle cap and the bottle mouth, improving the overall safety and reliability of the product.

[0027] Furthermore, the bottom of the lower piercing cap 10 is connected to the bottle opening via an anti-theft ring 16. This design not only strengthens the connection between the bottle cap and the bottle opening but also serves as a theft deterrent. Once the anti-theft ring 16 is damaged or removed, it cannot be restored to its original state, effectively preventing unauthorized opening and misappropriation of the product.

[0028] Furthermore, an anti-theft ring retaining latch 11 is provided on the top outer side of the lower piercing cap 10. This retaining latch 11 engages with the tear-off-type anti-theft ring 2. This design allows the user to easily identify and tear off the anti-theft ring 2 when opening the bottle cap for the first time, while also ensuring that the anti-theft ring remains securely attached to the bottle cap until it is damaged. This design not only improves product safety but also provides users with intuitive opening instructions, enhancing user convenience.

[0029] When using the present invention's bottom-slapped, sealed-bottom, inner-opening solid-liquid separation bottle cap, the bottle cap is initially unopened. The bottom-slapped cap 1 and the lower piercing cap 10 are connected by a tear-off, anti-theft ring 2, ensuring that the cap cannot be easily opened without authorization. Ultrasonic welding of the melt channel 5 and the bottom-opening, sealed-bottom welding ring 6 creates a tight seal between the silo wall 3 and the lower inner-opening sealed bottom 7. The water-sealing buckle 4 also enhances the sealing effect, ensuring that liquid or solid materials within the product are not leaked. The inner and outer seals 14 and the cap screw threads 15 further enhance the cap's sealing performance and securely screw it onto the bottle opening.

[0030] The user tears off the tear-off anti-theft ring 2 and then presses down on the lower flap 1 to open the bottle cap. This action moves the lower inner opening sealing bottom 7 downward, while the piercing cone 13 of the lower piercing cap aligns with the center of the lower inner opening sealing bottom 7 and pierces the opening position 9. As the lower flap 1 continues to be pressed downward, the piercing cone 13 of the lower piercing cap punctures the lower inner opening sealing bottom 7, breaking along the sealing bottom easy-opening line 8, achieving solid-liquid separation. During this process, the lower piercing cap water-sealing wall 12 tightly mates with the silo barrel wall 3, forming an additional sealing barrier to prevent liquid or solid materials from splashing or scattering during the opening process.

[0031] After the bottle cap is opened, the user can easily pour out or remove the liquid or solid material inside the product. The tear-off anti-theft ring 2 is broken when the bottle cap is first opened and cannot be restored to its original state, thus playing a theft-proof role. The anti-theft ring fixing position 11 ensures that the anti-theft ring 2 is firmly fixed to the bottle cap before it is broken, providing the user with an intuitive opening instruction.
