Detailed Implementation

[0024] 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.

[0025] This utility model provides an embodiment: Please refer to Figures 1-8 A universal aseptic filling and unloading cap device for a filling machine includes an unloading cap and a material handling assembly. The unloading cap is an improvement on the existing universal 1-inch cap. The unloading cap includes an outer cylinder 1, an inner cylinder 2, and a dust cover. The outer cylinder 1 has the same shape as the existing universal 1-inch cap, and its outer diameter is the same as that of the existing 1-inch cap. The outer side wall of the outer cylinder 1 is provided with a connecting thread 6, which allows the unloading cap to be connected to the universal 1-inch cap adapter base.

[0026] like Figures 1 to 3 As shown, the outer cylinder 1 includes a central cylinder, the outer side wall of which is provided with connecting threads 6, and the top of the central cylinder is provided with an annular flange. The cross-section of the annular flange is right-angled, and the vertical part of the annular flange is provided with rounded corners.

[0027] The inner cylinder 2 is located inside the outer cylinder 1. The bottom end of the outer cylinder 1 is connected to the bottom end of the inner cylinder 2, and a deformation gap 13 is formed between the outer cylinder 1 and the inner cylinder 2. The deformation gap 13 provides a certain deformation space for the inner cylinder 2, allowing the dust cover and the inner cylinder 2 to achieve an interference fit during use. Reinforcing ribs 3 are evenly arranged within the deformation gap 13 to improve the strength of the unloading cover. The top of the inner cylinder 2, the top of the horizontal end of the annular flange, and the top of the outer cylinder 1 are at the same height. An internal thread 4 is provided at the bottom end of the inner cavity of the inner cylinder 2.

[0028] The dust cover is compatible with the inner cavity of the unloading cover. The dust cover includes a sealing plate 7 and a retaining ring 10 connected to the bottom of the sealing plate 7. The retaining ring 10 is compatible with the top of the inner cavity of the inner cylinder 2, and the retaining ring 10 and the top of the inner cavity of the inner cylinder 2 can be locked together to prevent the dust cover from falling off during packaging and transportation. The sealing plate 7 is compatible with the horizontal end of the annular flange. When the dust cover is locked with the inner cavity of the inner cylinder 2, the sealing plate 7 can seal the deformation gap 13 and protect the deformation gap 13 from dust. The material of the dust cover can be set according to requirements and is not limited here.

[0029] The sealing plate 7 has a kidney-shaped design to facilitate the removal of the dust cover during end-use applications. In addition, a groove is provided in the middle of the top of the sealing plate 7. One end of the groove is movably connected to a lifting rod 8, and a lifting gap 9 is provided between the other end of the groove and the lifting rod 8. The lifting rod 8 is engaged with the groove. With the lifting rod 8, when removing the dust cover, the user can rotate the lifting rod 8 to make the lifting rod 8 vertical, and then use the lifting rod 8 to lift the dust cover, improving the convenience of removing the dust cover.

[0030] The bottom of the inner cylinder 2 is provided with a sealing film 5. The material of the sealing film 5 can be selected according to the requirements and is not restricted here. Preferably, the material of the sealing film 5 is a high-strength aluminum foil film.

[0031] As described above, during use, the dust cover protects the inner cavity of the inner cylinder 2. When the dust cover is open, the sealing film 5 seals the beverage storage container, preventing the beverage from being exposed to the open environment and ensuring the aseptic state of the beverage after filling.

[0032] The material handling assembly includes a connecting pipe 11 threaded to the inner cylinder 2 and a three-pronged piercing tool 17 that engages with the inner cavity of the connecting pipe 11. The outer wall of the bottom end of the connecting pipe 11 is sequentially provided with a limiting plate 12 adapted to the top of the outer cylinder 1, an inverted conical sealing ring 15 adapted to the inner cavity of the inner cylinder 2, and an external thread 16 adapted to the internal thread 4. Using the external thread 16 and the internal thread 4, the connecting pipe 11 and the inner cylinder 2 can be threadedly connected. When the connecting pipe 11 and the inner cylinder 2 are threadedly connected, the inverted conical sealing ring 15 engages with the inner cavity of the inner cylinder 2, achieving a seal between the material handling assembly and the unloading cover. The top end of the connecting pipe 11 connects to the flexible hose of the in-situ mixing machine. The material of the inverted conical sealing ring 15 can be set according to requirements and is not limited here.

[0033] Limiting plates 12 are provided on both sides of the bottom end of the connecting pipe 11 to improve the effort-saving when screwing the connecting pipe 11. The bottom of the limiting plate 12 is provided with a limiting groove 14 that matches the vertical end of the annular flange. The setting of the limiting groove 14 can determine whether the connecting pipe 11 has moved into place.

[0034] The fork of the three-pronged puncture device 17 adopts a right-angle step transition design between the fork head and the fork body. The fork head of the three-pronged puncture device 17 maintains a planar contact with the end face of the connecting tube 11. With this setting, the right-angle step transition design of the three-pronged puncture device 17 can play a positioning function during installation, making it easy to determine whether the three-pronged puncture device 17 has moved into place. The inner cavity of the connecting tube 11 is provided with a clamp 18, and the fork body of the three-pronged puncture device 17 is engaged with the clamp 18. Through the setting of the clamp 18, the three-pronged puncture device 17 can be quickly disassembled and assembled, which is convenient for the assembly and cleaning of the material picking component.

[0035] In summary: When using the aseptic filling and unloading universal cap device for this instant beverage dispenser, the unloading cap seals the beverage filling container. To connect the beverage filling container to the dispenser, the user removes the dust cap, and the beverage filling container is sealed by the sealing film 5, maintaining the aseptic state of the beverage after filling. The user inserts the connecting tube 11 into the inner cavity of the inner cylinder 2 and screws it to connect it threadedly to the inner cylinder 2. When the top of the limiting groove 14 contacts the top of the annular flange, the connecting tube 11 and the inner cylinder 2 are reliably connected. During the screwing process, the fork of the three-pronged piercing tool 17 can pierce the sealing film 5, allowing the bottom end of the material-taking component to be inserted into the beverage filling container. When the end of the connecting tube 11 away from the unloading cap connects to the dispenser's hose, the beverage flows into the dispenser through the material-taking component, achieving aseptic unloading.
