Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a piercing component for pressing and piercing the sealed bottom of an integrally formed solid-liquid separation bottle cap. Background Art

[0002] In the existing field of solid-liquid separation bottle caps, a common application is for packaging solid beverages or concentrated liquid beverages. These caps are designed to be combined with bottled water. When used, pressing the cap causes the top of the cap to penetrate the cone and break the sealing bottom of the lower cap, allowing the solid beverage or concentrated liquid in the cap to mix and dissolve with the water in the bottle for consumption. This design not only facilitates user use but also improves the convenience and practicality of the product.

[0003] However, traditional press-on solid-liquid separation bottle caps have some significant manufacturing drawbacks. In particular, due to the limitations of integrated injection molding technology, the diameter of the piercing cone cannot be made very large, resulting in a relatively small opening area after the bottom seal of the bottle cap is broken. This small opening design often leads to material jamming in actual use, meaning that solid beverages or concentrated liquids cannot smoothly fall into the bottle, but partially remain in the bottle cap, affecting the product's dissolution and the user's drinking experience.

[0004] In order to overcome this technical difficulty, the industry has been continuously exploring and improving. It is in this context that the present invention was proposed. It breaks through the limitations of traditional one-piece injection molding technology and adopts an innovative design concept. Specifically, the present invention disassembles the piercing member in the one-piece upper sealing cover for separate injection molding, and then fixes it to the upper sealing cover in combination with a latch barrel. This design allows the expansion cone of the piercing member to be enlarged to its maximum volume, thereby forming a larger opening area when breaking through the sealed bottom of the bottle cap. In this way, the material in the bottle cap can fall into the water bottle more easily, avoiding the problem of material jamming, improving the dissolution effect of the product and the user's drinking experience. Utility Model Content

[0005] The present invention aims to provide a piercing element for pressing and piercing the sealed bottom of an integrally molded solid-liquid separation bottle cap, thereby resolving some of the significant drawbacks in the manufacturing process of conventional press-type solid-liquid separation bottle caps mentioned in the background art. In particular, due to the limitations of integral injection molding technology, the diameter of the piercing cone cannot be made very large, resulting in a relatively small opening area after the sealed bottom of the bottle cap is pierced.

[0006] To achieve the above-mentioned purpose, the utility model provides a puncturing member for pressing and puncturing the sealed bottom of an integrally formed solid-liquid separation bottle cap, comprising a puncturing member assembly pin, a fixing ring being installed at the bottom of the puncturing member assembly pin, a support cone being installed at the bottom of the fixing ring, a puncturing member piercing cone head being provided at the bottom end of the support cone, an upper sealing cover being provided on the upper part of the puncturing member assembly pin, the upper sealing cover being covered on the top of the bottle cap shell, a sealing member being installed on the inner side of the bottle cap shell, and the puncturing member piercing cone head being located above the sealing member.

[0007] Preferably, the expansion cone is composed of a plurality of flat triangular plates, forming a conical frame structure at the bottom of the fixing ring, and the fixing ring and the expansion cone are an integrally-molded structure by injection molding.

[0008] Preferably, a circle of puncture component assembly pin buckles are installed on the outer wall of the puncture component assembly pin, an upper sealing cover pin barrel is installed on the bottom of the upper sealing cover, the puncture component assembly pin is plugged into the upper sealing cover pin barrel, and a circle of protrusions are provided on the inner wall of the upper sealing cover pin barrel, and the protrusions are snap-fitted into the puncture component assembly pin buckles.

[0009] Preferably, the bottom end of the piercing member that penetrates the cone head is a conical structure.

[0010] Preferably, the piercing cone head of the piercing member is made of titanium alloy material.

[0011] Preferably, the upper sealing cover is made of PVC material.

[0012] Preferably, a sealing ring is provided on the outer side of the bottom of the upper sealing cover, and a sealing groove is provided on the outer side of the top of the bottle cap shell, and the sealing ring is snap-fitted with the sealing groove.

[0013] Preferably, a cavity is provided on the upper portion of the sealing member and the bottom of the upper sealing cover for placing materials.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The piercing element of this integrated, press-to-pierce solid-liquid separation bottle cap has been designed to expand its expansion cone to its maximum volume, creating a larger opening area when the bottle cap seal is breached. Compared to traditional designs, this significantly reduces the amount of solid beverage or concentrated liquid left inside the bottle cap, avoiding material jams and ensuring smooth material delivery into the bottle, improving product dissolution and the user's drinking experience.

[0016] By separating the piercing element from the integrally molded upper sealing cover and performing separate injection molding, and then securing it to the upper sealing cover via a latch-barrel design, the present invention enhances manufacturing flexibility. This design frees the manufacturing of the piercing element from the limitations of integral injection molding technology, allowing for greater flexibility in adjusting the size and shape of the expansion cone to meet the needs of different products.

[0017] The piercing element assembly pin and the upper sealing cap latch barrel in this utility model form a stable structural connection through plugging and snapping. Furthermore, the expansion cone is composed of several flat triangular plates, forming a tapered frame structure, further enhancing the structural stability of the piercing element. This design ensures that the piercing element can stably penetrate the bottom seal of the bottle cap during the pressing process, improving the reliability and durability of the product.

[0023] 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.

[0024] The utility model provides a piercing member for pressing and piercing the sealed bottom of an integrally formed solid-liquid separation bottle cap, such as Figure 1-Figure 3As shown, it includes a puncture member assembly pin 1, a fixing ring 3 is installed at the bottom of the puncture member assembly pin 1, a support cone 4 is installed at the bottom of the fixing ring 3, and a puncture member top-penetrating cone head 5 is provided at the bottom end of the support cone 4. The upper part of the puncture member assembly pin 1 is provided with an upper sealing cover 6, which covers the top of the bottle cap shell 8. A sealing member 81 is installed on the inner side of the bottle cap shell 8, and the puncture member top-penetrating cone head 5 is located above the sealing member 81. The combined design of the puncture member assembly pin 1, the fixing ring 3, the support cone 4 and the puncture member top-penetrating cone head 5 forms an integrated puncture structure. This design not only simplifies the assembly process, but also improves the convenience of use, allowing users to easily achieve solid-liquid separation when pressing the bottle cap.

[0025] The piercing cone 5 is located above the sealing member 81, and its conical design ensures that the sealing member 81 is accurately pierced during the pressing process, thereby achieving solid-liquid separation. At the same time, this design also ensures that a good seal is formed between the bottle cap shell 8 and the upper sealing cover 6 before being pressed, preventing leakage of the internal material.

[0026] The provision of the expansion cone 4 not only enhances the structural strength of the piercing element, but also effectively expands the punctured portion through its conical structure when piercing the sealing element 81, thereby expanding the opening area. This helps the material flow out more smoothly and avoids the problems of material jamming or clogging that may occur in traditional designs.

[0027] The overall structural design takes into account the user's usage habits and needs, making the pressing process easier and smoother. At the same time, the integrated design and precise puncture function also improve the reliability and stability of the product, thus providing users with a better user experience.

[0028] In this embodiment, the expansion cone 4 is composed of several flat triangular plates, forming a tapered frame structure at the bottom of the retaining ring 3. The retaining ring 3 and the expansion cone 4 are integrally injection-molded. This design not only enhances the structural strength of the expansion cone 4 but also more evenly distributes pressure when puncturing the seal, ensuring smooth and complete puncture. Furthermore, the integral injection-molded structure of the retaining ring 3 and the expansion cone 4 improves overall manufacturing precision and stability, reduces errors during assembly, and enhances product reliability and durability.

[0029] Specifically, the outer wall of the piercing element assembly pin 1 is equipped with a circle of piercing element assembly pin buckles 2, and the bottom of the upper sealing cover 6 is equipped with an upper sealing cover latch barrel 7. The piercing element assembly pin 1 is plugged into the upper sealing cover latch barrel 7. The inner wall of the upper sealing cover latch barrel 7 is provided with a circle of protrusions 71, which snap into the piercing element assembly pin buckles 2. This achieves a stable connection between the piercing element and the upper sealing cover. This connection method is not only simple and easy to use, but also ensures the stability and accuracy of the piercing element during the pressing process, avoiding puncture failure or material leakage caused by loose connections.

[0030] Furthermore, the bottom end of the piercing member, where it penetrates the cone head 5, is tapered. This design allows for easier penetration of the material when piercing the seal, reducing resistance during the piercing process and improving piercing efficiency. Furthermore, the tapered structure better guides material outflow, avoiding material blockage caused by irregularly shaped piercing openings.

[0031] Furthermore, the piercing cone head 5 of the piercing element is made of titanium alloy. This material has the advantages of high strength, corrosion resistance, and light weight. It not only easily handles piercing tasks in various complex environments, but also extends the service life of the piercing element and reduces product maintenance costs.

[0032] Furthermore, the upper sealing cap 6 is made of PVC material. This material has good sealing properties, flexibility, and corrosion resistance. It not only ensures that the bottle cap maintains a good sealing state before being pressed, but also adapts to the use requirements in different environments, thereby improving the adaptability and reliability of the product.

[0033] Furthermore, a sealing ring is provided on the bottom outer side of the upper sealing cap 6, and a sealing groove is provided on the top outer side of the bottle cap shell 8. The sealing ring engages with the sealing groove. This design further enhances the sealing performance of the bottle cap. The sealing ring fits tightly within the sealing groove, forming an effective sealing barrier, preventing leakage of internal materials and ingress of external impurities.

[0034] Furthermore, a cavity is provided between the upper portion of the sealing member 81 and the bottom of the upper sealing cap 6 for storing materials. This design not only fully utilizes the space inside the bottle cap, but also allows materials to be more evenly distributed within the cavity, improving the efficiency and convenience of the product. Furthermore, the cavity design also makes it easier for users to monitor the remaining materials and replenish or replace them in a timely manner.

[0035] When using the piercing element of the integrated, press-to-pierce solid-liquid separation bottle cap, the piercing element assembly pin, retaining ring, opening cone, and piercing cone head are assembled to form an integrated piercing structure, which is securely connected together. The upper sealing cap is placed on top of the bottle cap shell and tightly cooperates with the sealing element inside the bottle cap shell to form a good seal and prevent leakage of internal materials.

[0036] To achieve solid-liquid separation, the user begins pressing the piercing element assembly pin. As the pressure continues, the piercing element's piercing cone gradually approaches and contacts the seal. Because of its conical design, the piercing element's piercing cone easily penetrates the seal, achieving solid-liquid separation.

[0037] As the piercing element pushes through the cone head and punctures the seal, the expansion cone begins to work. The conical structure of the expansion cone effectively expands the punctured area, expanding the opening area and ensuring smooth outflow of materials.

[0038] Once the seal is punctured, the liquid portion of the solid-liquid mixture begins to flow out through the enlarged opening, while the solid portion remains inside the bottle cap shell, achieving effective separation of solid and liquid.

[0039] The piercing cone tip of the piercing device is made of titanium alloy, offering high strength, corrosion resistance, and lightweight properties. This ensures a smooth piercing process and extends the life of the piercing device. The upper sealing cap is made of PVC, offering excellent sealing, flexibility, and corrosion resistance, adapting to diverse operating environments. The sealing ring and sealing groove further enhance the cap's sealing performance, preventing leakage of internal materials and the ingress of external impurities.

[0040] The user can replenish or replace the material in time by observing the remaining material in the cavity.

[0041] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
