Description

Technical Field

[0001] This invention relates to the field of packaging box technology, specifically to a cat food packaging box with a food divider structure and its processing and molding method. Background Technology

[0002] Cat food is a pet-specific food formulated according to the physiological characteristics of felines. It is rich in core nutrients such as protein and fat. Protein can help felines grow muscles and repair tissues, while fat can provide efficient energy for their daily activities and life functions. The two types of nutrients work together to comprehensively ensure the growth and development of felines, providing sufficient energy support and balanced nutrition for maintaining their physiological functions and carrying out daily activities.

[0003] Given that core nutrients such as protein and fat are easily affected by external environmental factors such as air, moisture, and light, and that cat food pellets are easily crushed during transportation and storage, leading to product deterioration due to moisture, bacterial growth, and loss of flavor, packaging cat food in boxes can effectively isolate it from external adverse factors, preventing the oxidation and deterioration of nutrients and maintaining the integrity of the cat food pellets and the stability of their flavor.

[0004] To meet the needs of cats for balanced nutrition, improved palatability, and adaptation to diverse feeding scenarios, cat food packaging often adopts a combination of dry and wet food. This design is commonly seen in complete nutritional combination food, transitional food for kittens during weaning, functional customized food for senior cats that is easy to digest, and portable feeding kits. It can satisfy the cat's physiological habit of grinding and cleaning its teeth with dry cat food, and can also supplement the cat's water and increase its appetite with liquid cat food. This allows owners to easily achieve scientific feeding of their cats without additional preparation, and flexibly adapt to various scenarios such as daily family feeding and short-distance travel boarding.

[0005] Currently available pet food packaging commonly uses a direct pouring method when feeding cats. During this process, the contents of the packaging become empty as the food is removed, allowing outside air to easily penetrate the packaging. This is especially true for liquid cat food. As the number of feedings increases, the frequency and amount of air intrusion also rise, significantly accelerating the oxidation and spoilage of the remaining cat food. This not only makes it difficult to ensure the freshness of the remaining cat food for reuse but also significantly increases the probability of cats experiencing gastrointestinal discomfort and other health problems from consuming spoiled cat food. Therefore, this paper proposes a cat food packaging box with a food divider structure and its processing method to address these issues. Summary of the Invention

[0006] The purpose of this invention is to provide a cat food packaging box with a food divider structure and its processing and molding method, so as to solve the problems mentioned in the background art.

[0013] As a further optimization of the present invention, the dry food separator includes a circular plate, the top end of which is fixedly connected to the bottom end of the disc shell, and the top end of which is fixedly connected to the bottom end of the silicone capsule.

[0014] As a further optimization of the present invention, wherein: an arc-shaped plate and an annular shell are fixedly connected to the bottom end of the circular plate in sequence; a second silicone ring is fixedly connected to the outer side of the circular plate; a third silicone ring is fixedly connected to the outer side of the annular shell near the upper end; a spiral groove is formed on the inner side of the annular shell; an extension column including a sealing assembly is fixedly connected to the bottom end of the circular plate; a first partition and a second partition are fixedly connected to the outer side of the extension column; a third silicone pad is fixedly connected to the bottom end of the first partition; a first silicone pad is fixedly connected to the top end of the second partition; and a dry food box assembly is installed on the inner side of the annular shell.

[0015] As a further optimization of the present invention, the dry food box assembly includes a dry food divider box. An internal threaded groove is formed on the inner side of the dry food divider box near its lower end. A second rubber pad is fixedly connected to the outer side of the dry food divider box near its lower end. A first silicone ring is fixedly connected to the outer side of the dry food divider box near its upper end. A spiral strip is fixedly connected to the outer side of the dry food divider box.

A bottom cover is threadedly connected to the inner side of the internal threaded groove. The bottom end of the second rubber pad is fitted to the upper surface of the bottom cover. The inner side of the spiral groove is threadedly connected to the outer side of the spiral strip.

[0016] As a further optimization of the present invention, wherein: the outer side of the circular plate and the annular shell is fitted with a baffle cylinder including the sealing component, the inner side of the baffle cylinder is in contact with the outer side of the second silicone ring and the outer side of the third silicone ring, a desiccant sheet is fixedly connected to the inner side of the insert groove opened on the inner side of the baffle cylinder, the bottom end of the desiccant sheet is in contact with the top end of the second spring, a rubber sleeve is fixedly connected to the bottom end of the second spring, and the top end of the baffle cylinder is in contact with the bottom end of the disc shell.

[0017] A method for processing and molding a cat food packaging box with a food divider structure;

[0018] Step 1: Processing and Basic Assembly. A horizontal toggle injection molding machine is used to integrally mold the box body, feeding box, studs, wet food box, round plate, annular shell, sealing assembly, bottom cover, baffle, and dry food separator. The component disc shell is horizontally cut in half and injection molded separately. The rear end of the shell is embedded inside the cylindrical groove, and the push plate is positioned at the front end of the cylindrical groove. The rear end of the first spring is attached to the inner side of the disc shell near the front end of the cylindrical groove. The third duckbill valve of both components is fixed to the front end of the cylindrical groove with sealant. The flow regulating assembly is installed into the right-end screw hole, aligning the first duckbill valve. The valve port faces the same direction as the third duckbill valve on the right end. Rotate the ring handle to connect the threaded cylinder to the threaded hole. The first duckbill valve fits against the front end of the push plate. The sealing block seals with the push plate through the rubber gasket. The outside of the silicone tube is glued and fixed to the front of the first internal cylinder. The sealing plate is threaded to the inner side of the rear end of the disc shell and squeezes the rear end of the silicone tube. The two halves of the disc shell are aligned and welded and fixed. The upper end of the silicone capsule is fixed to the bottom end of the wet grain box. The mounting base is heat-fused and fixed to the wet grain box. The second silicone gasket is embedded in the threaded nozzle and fits tightly against its inner side and the wet grain box, ensuring that the threaded nozzle fits the second silicone gasket.

[0019] Step 2: Assembly and Dry Cat Food Filling. The arc plate and the ring shell are integrated into one structure and are fixed to the round plate by heat fusion. The extension column is heat fused to the round plate and is integrated with the first partition. The spiral strip is embedded in the spiral groove. The dry food divider box is inserted into the ring shell and extends to the feed inlet. Its top end is attached to the bottom end of the third silicone pad. The second partition and the extension column are heat fused. The outer side of the first silicone ring is attached to the inner side of the ring shell. The dry food divider box is fixed to the spiral strip. The baffle is sleeved on the outer side of the ring shell and the round plate through the dry food divider box. The second spring and the rubber sleeve are sleeved on the outer side of the dry food divider box. The second spring makes the top end of the baffle stick to the bottom end of the disc shell. Dry cat food is put into the dry food divider box. The bottom cover is threaded to the inner thread groove until the second rubber pad is attached to the bottom cover. The wet food divider component is placed into the box body with the wet food box placed on the top of the baffle ring. The stud is threaded to the spiral groove and presses the top of the wet food box.

[0020] Step 3: Liquid cat food feeding quantity control. Separate the stud and spiral groove, remove the device inside the box and reset the stud. Rotate the sealing block to disengage it from the push plate. External air enters the cylindrical groove at the left end through the first rubber pad at the left end. At this time, the valve ports of the first duckbill valve and the third duckbill valve at the right end are in the same direction. The pressure regulating chamber is connected to the screw hole. The gap between the first duckbill valve sealing ring handle and the push plate is closed. Press the push plate backward to move the cylinder shell and squeeze the first spring. The third duckbill valve blocks the airflow. The gas in the cylindrical groove at the right end is discharged from the first duckbill valve through the vent. The cylinder shell and push plate are reset by the elastic force of the first spring, so that the cylindrical groove and the pressure regulating chamber are under-pressured in sequence. The liquid cat food in the liquid storage bag flows into the silicone capsule through the threaded nozzle and the second duckbill valve to expand it. When the silicone capsule fits the pressure regulating chamber, the dosage is controlled to be 60ml-80ml.

[0021] Step 4: When dispensing liquid cat food, the second duckbill valve restricts the flow rate, the sealing plate keeps the silicone tube sealed, separate the two first rubber pads from the push plate, and the sealing block from the left end screw hole, allowing external air to enter the pressure regulating chamber to balance the air pressure. Install the sealing block into the right end screw hole and the threaded cylinder into the left end screw hole, so that the valve openings of the first duckbill valve and the left end third duckbill valve are in the same direction. Adjust the silicone tube to face the feeding trough, remove the sealing plate, and use the elastic return force of the silicone capsule and silicone tube to make the liquid cat food drip into the feeding trough through the silicone tube. Press the push plate to circulate and push the airflow to empty the silicone capsule and silicone tube. Finally, reset the sealing plate to seal the silicone tube, and the sealing block and threaded cylinder return to their positions.

[0022] Step 5: When feeding dry cat food, press and rotate the rubber sleeve to make the dry food divider box rotate and rise to its limit inside the annular shell. Flip the dry food divider box so that the liquid food storage bag is facing down and shake it. The dry cat food enters the baffle. When the dry cat food is about to touch the first partition, reset the dry food divider box. Excess cat food falls back through the feed inlet. The third silicone pad adheres to the dry food divider box. Move the baffle to squeeze the second spring and then release it. The elasticity of the second spring makes the baffle adhere to the disc shell and the outer side of the second silicone ring and the first silicone ring to form a sealed cavity. After drying with the desiccant sheet, the feeding preparation is complete.

[0023] Step Six: Clean and maintain the device. Separate the threaded nozzle from the mounting base, and the bottom cover from the dry food separator box. Remove the rubber sleeve, the second spring, and the baffle, and replace the desiccant sheet. Operate the dry food separator box according to the principle in Step Three to unblock the feed inlet. Rinse the dry food separator box, baffle, sealing assembly, feed inlet, round plate, and annular shell with pure water. Remove the sealing plate. Insert the water spray nozzle into the mounting base to rinse the mounting base, the second duckbill valve, the silicone capsule, and the silicone tube. Then dry the above components with a hot air blower.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In this invention, by setting up the movable cylinder component, sealing block and silicone capsule, the device abandons the traditional tilting feeding method and innovatively adopts a new feeding structure. In the process of multiple feedings, it can effectively avoid the formation of volume gaps inside the packaging after the cat food is removed, thereby preventing the outside air from entering the packaging. This design greatly reduces the risk of cat food oxidation and deterioration, effectively ensures the freshness of the remaining cat food for secondary consumption, and significantly reduces the probability of cats experiencing gastrointestinal discomfort and other health problems due to eating spoiled cat food, providing a reliable guarantee for the cat's dietary health.

[0026] 2. In this invention, the device, through the dry food box assembly, baffle, and desiccant sheet, provides an independent, isolated, and sealed drying chamber for dry cat food. This chamber is specifically designed for the dispensing and storage of dry cat food. During the storage of dry cat food, the chamber can be completely isolated from the air while maintaining a stable dry environment inside. This prevents the dry cat food from being affected by direct contact with air. During the dispensing process, the storage chamber is automatically sealed to prevent air from seeping in during the dispensing process. After dispensing, the device performs a secondary drying process on the isolated and sealed drying chamber to prepare it for the next feeding, effectively extending the shelf life of the dry cat food and further improving its safety for consumption.

[0027] 3. In this invention, the device adopts an easy-to-clean structural design through the setting of sealing plate, bottom cover and baffle. All parts that come into contact with cat food can be easily disassembled and cleaned, which can effectively remove cat food residues during feeding and storage, avoid the growth of microorganisms from residual dirt, prevent cross-contamination, and ensure that the device is in a clean state every time it is reused. This further ensures the safety of cat food from the usage stage and builds a solid defense for the health of cats.

[0028] 4. In this invention, the device adopts a reusable main structure design through the set box body, tray shell and dry food divider box. When the cat food is used up, there is no need to replace the entire packaging structure. This design greatly reduces the consumption of packaging materials, reduces the long-term economic investment of pet owners, and significantly enhances the competitiveness of the product in the pet food packaging market.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0038] Please see Figures 1-15 The present invention provides a technical solution:

[0039] A cat food packaging box with a food divider structure and its processing method are disclosed. The box includes an outer packaging component 1, a wet food divider component 2, and a dry food divider component 5. A feeding operation component 3 is installed at the lower end of the wet food divider component 2, and a pre-storage component 4 is installed inside the feeding operation component 3. A sealing component 6 is installed on the outer side of the dry food divider component 5. The wet food divider component 2 includes a wet food box 21, with a mounting base 22 and a second silicone pad 23 fixedly connected to the inner side of the wet food box 21. A through-hole at the lower end of the wet food box 21 is fixedly connected to... There is a second duckbill valve 24. The bottom of the wet grain box 21 is fixedly connected to a feeding operation component 3, including a disc shell 31. A pressure regulating chamber 32 is opened on the inner side of the disc shell 31. A first internal cylinder 34 and a second internal cylinder 35 are fixedly connected to the inner side of the disc shell 31. Two third duckbill valves 37 are fixedly connected to the inner side of the rear end of the second internal cylinder 35. The rear end of the first internal cylinder 34 is fixedly connected to a pre-storage component 4, including a sealing plate 41. The front end of the sealing plate 41 is tightly attached to a silicone tube 42. The front end of the silicone tube 42 is fixedly connected to a silicone capsule 43.

[0040] As a further implementation of this solution, the outer packaging component 1 includes a box body 11. A retaining ring 12 is fixedly connected to the inner side of the box body 11. A spiral groove 13 is formed near the upper end of the box body 11. A stud 15 is threadedly connected to the inner side of the spiral groove 13. A feeding box 14 is fixedly connected to the top of the stud 15. A feeding slot 16 is formed inside the feeding box 14. An inclined surface 17 is formed at the upper end of the feeding box 14. A wet food box 21 is embedded inside the box body 11. The upper end of the wet food box 21 is placed on the upper end of the retaining ring 12. The bottom end of the stud 15 is connected to the top end of the wet food box 21. The above-mentioned setup provides bottom support for the wet food container 21. Combined with the threaded connection between the stud 15 and the spiral groove 13, it precisely secures the top of the wet food container 21, effectively preventing it from shaking inside the container 11 and ensuring the overall structural stability of the device. This ensures that all components move in unison during feeding. The feeding trough 16 in the feeding box 14 serves as the cat's feeding cavity, and the 25-degree inclined surface 17 of the threaded nozzle conforms to the pet's eating habits, reducing the risk of the cat's esophagus being obstructed by foreign objects.

[0041] As a further implementation of this solution, a threaded nozzle 25 is threadedly connected to the inner side of the mounting base 22. A liquid grain storage bag 26 is fixedly connected to the top of the threaded nozzle 25, and the bottom of the threaded nozzle 25 is attached to the top of the second silicone pad 23. The top of the silicone capsule 43 is fixedly connected to the bottom of the wet grain box 21. The valve port of the second duckbill valve 24 is located at the upper end of the silicone capsule 43. The outer side of the sealing plate 41 is threadedly connected to the rear end of the disc shell 31. The inner side of the silicone capsule 43 and the silicone tube 42 are installed in the middle of the inner side of the pressure regulating chamber 32. Through the above configuration, the threaded connection structure facilitates the disassembly and assembly of the threaded nozzle 25 and the mounting base 22, making it convenient for subsequent cleaning and replacement of components such as the mounting base 22, the second duckbill valve 24, and the silicone capsule 43, while ensuring a sealed connection. To prevent liquid cat food leakage, the fitting design of the second silicone pad 23 and the bottom of the threaded nozzle 25 further enhances the sealing performance, preventing liquid cat food from overflowing from the connection point during storage and feeding, ensuring the cleanliness of the device and reducing food waste. The silicone capsule 43 is firmly connected to the wet food box 21, and its installation position ensures that liquid cat food flows accurately into the interior, achieving quantitative dispensing in conjunction with the silicone tube 42. The sealing plate 41 seals the silicone tube 42 through a threaded connection, preventing leakage when not feeding. The connection structure between the silicone capsule 43 and the silicone tube 42 can use its own elasticity and air pressure to completely squeeze out any residual liquid cat food, reducing food residue and the risk of spoilage, and ensuring the freshness of each feeding.

[0042] As a further implementation of this solution, the valve ports of the two third duckbill valves 37 are oriented in opposite directions. A movable cylinder assembly 38 is installed inside the two cylindrical grooves 36 of the second built-in cylinder 35. The movable cylinder assembly 38 includes a cylinder shell 381. A first rubber sealing ring 384 is fixedly connected to the outside of the cylinder shell 381, and the outside of the first rubber sealing ring 384 fits against the inside of the cylindrical groove 36. A push plate 382 is fixedly connected to the front end of the cylinder shell 381. A vent 383 is opened inside the cylinder shell 381. A screw hole 385 is opened inside the push plate 382. A first spring 386 is fixedly connected to the rear end of the push plate 382. A sealing block 39 is threadedly connected to the inside of the screw hole 385 at the left end, and an annular handle 331, including the flow regulating assembly 33, is threadedly connected to the inside of the screw hole 385 at the right end. The above-described configuration, with the two third duckbill valves 37 having their valve ports arranged in opposite directions, allows for precise control of unidirectional airflow. Combined with the sliding connection between the cylinder shell 381 and the cylindrical groove 36, and the sealing effect of the first rubber sealing ring 384, it enables directional gas delivery and pressure balance, preventing disorderly intrusion of external air into the pressure regulating chamber 32. The tight fit between the first rubber sealing ring 384 and the inner side of the cylindrical groove 36 enhances the sealing performance, preventing gas leakage from affecting the pressure regulation effect. The elastic design of the first spring 386 can drive the cylinder shell 381 and the push plate 382 to automatically reset, ensuring smooth pressure regulation circulation without additional manual operation, thus improving the ease of use of the device. The threaded connection between the annular handle 331 and the screw hole 385 allows for the disassembly, assembly, and maintenance of the flow regulating component 33, while ensuring the stability of the connection.

[0043] As a further implementation of this solution, threaded cylinders 332 are fixedly connected to both ends of the annular handle 331. Straight holes 335 are opened on the inner side of both the annular handle 331 and the threaded cylinder 332. First rubber pads 334 are fixedly connected to both ends of the annular handle 331. The push plate 382 and the annular handle 331 are sealed by the first rubber pads 334. A first duckbill valve 333 is fixedly connected to the inner side of the annular handle 331 through the straight holes 335. Through the above settings, the first rubber pads 334 can effectively enhance the sealing between the push plate 382 and the annular handle 331, prevent airflow from leaking from the connection, and ensure the accuracy of air pressure regulation. The first duckbill valve 333 is firmly fixed through the straight holes 335. Its valve port can cooperate with the third duckbill valve 37 to achieve precise control of airflow direction, ensuring that outside air enters the device in an orderly manner only in designated links, avoiding a large amount of air intrusion that causes cat food to oxidize and deteriorate. The design of the threaded cylinder 332 can improve the structural strength of the annular handle 331.

[0044] As a further implementation of this solution, the dry food separator component 5 includes a circular plate 51. The top end of the circular plate 51 is fixedly connected to the bottom end of the disc shell 31, and the top end of the circular plate 51 is fixedly connected to the bottom end of the silicone capsule 43. Through the above arrangement, the circular plate 51 can achieve a stable connection with the disc shell 31 and the silicone capsule 43, and the circular plate 51 can also effectively block the port of the pressure regulating chamber 32 to form an independent dry and wet food storage space, avoid cross-contamination between dry cat food and liquid cat food, ensure the flavor and quality of the two ingredients, and at the same time provide stable support for the dry cat food storage chamber, ensuring that the dry cat food feeding structure and the liquid cat food feeding structure work together, and improve the overall integration of the device.

[0045] As a further implementation of this solution, an arc-shaped plate 52 and an annular shell 53 are sequentially fixedly connected to the bottom end of the circular plate 51. A second silicone ring 54 is fixedly connected to the outer side of the circular plate 51, and a third silicone ring 55 is fixedly connected to the outer side of the annular shell 53 near its upper end. A spiral groove 56 is formed on the inner side of the annular shell 53. An extension post 581, including the sealing assembly 58, is fixedly connected to the bottom end of the circular plate 51. A first partition 582 and a second partition 583 are fixedly connected to the outer side of the extension post 581. A third silicone pad 585 is fixedly connected to the bottom end of the first partition 582, and a first silicone pad 584 is fixedly connected to the top end of the second partition 583. A ring is installed on the inner side of the annular shell 53. Equipped with dry food box assembly 57, the circular plate 51, arc plate 52, and annular shell 53 are sequentially fixedly connected to form a stable dry cat food storage support structure. The second silicone ring 54 and the third silicone ring 55 provide a precise fitting and positioning surface for the baffle 61, ensuring the sealing performance of the sealed cavity. The combined design of the extension column 581, the first partition 582, and the second partition 583 can realize the orderly discharge and precise sealing of dry cat food. The fit between the third silicone pad 585 and the dry food separator box 571 can reliably seal the feed inlet 576, preventing dry cat food from leaking when not being fed, while also preventing air from entering the storage cavity and extending the shelf life of the dry cat food.

[0046] As a further implementation of this solution, the dry food box assembly 57 includes a dry food divider 571. The dry food divider 571 has an internal threaded groove 572 on its inner side near the lower end. A second rubber pad 573 is fixedly connected to the outer side of the dry food divider 571 near the lower end. A first silicone ring 575 is fixedly connected to the outer side of the dry food divider 571 near the upper end. A spiral strip 574 is fixedly connected to the outer side of the dry food divider 571. A feed inlet 576 is opened at the upper end of the dry food divider 571. An extension post 581 is embedded inside the feed inlet 576. A first partition 582 is located at the upper end of the feed inlet 576, and a second partition 583 is located at the lower end of the feed inlet 576. A bottom cover 59 is threadedly connected to the inner side of the internal threaded groove 572. The second rubber pad 573 is located at the bottom... The end is fitted to the upper surface of the bottom cover 59, and the inner side of the spiral groove 56 is threadedly connected to the outer side of the spiral strip 574. Through the above settings, the threaded connection between the spiral strip 574 and the spiral groove 56, combined with the rotation of the dry food separator 571, can realize the up and down movement of the dry food separator 571 inside the annular shell 53, accurately adjust the opening and closing state of the feed inlet 576, and realize the switching between dry cat food dispensing and sealing. The threaded connection between the bottom cover 59 and the inner thread groove 572 and the sealing of the second rubber gasket 573 can ensure the airtightness of the dry cat food storage cavity, prevent air intrusion and food leakage. The structural design of the extension column 581 embedded in the feed inlet 576 can accurately control the amount of dry cat food dispensed, avoid excessive dispensing and waste, and facilitate subsequent cleaning of residual food.

[0047] As a further implementation of this solution, the outer sides of the circular plate 51 and the annular shell 53 are fitted with a baffle 61, which is part of the sealing assembly 6. The inner sides of the baffle 61 are both in contact with the outer sides of the second silicone ring 54 and the third silicone ring 55. A desiccant sheet 65 is glued to the inner side of the insert groove 64 opened on the inner side of the baffle 61 by a single-component room temperature vulcanizing RTV silicone adhesive. The bottom end of the desiccant sheet 65 is in contact with the top end of the second spring 62. A rubber sleeve 63 is fixedly connected to the bottom end of the second spring 62. The top end of the baffle 61 is in contact with the bottom end of the disc shell 31. Through the above arrangement, the baffle 61 and the second silicone ring 54 are sealed together. The tight fit of the rubber ring 54, the third silicone ring 55, and the disc shell 31 forms an independent dry cat food isolation and drying sealed cavity, isolating air and moisture from the source and ensuring a dry storage environment for the dry cat food. The desiccant sheet 65, as a drying component, can continuously maintain a dry environment inside the cavity, further extending the shelf life of the dry cat food and facilitating regular replacement to ensure the drying effect. The elasticity of the second spring 62 can drive the baffle 61 to automatically reset, ensuring the sealing of the cavity. The rubber sleeve 63 facilitates the manual operation of the baffle 61's movement and rotation, improving the convenience of feeding dry cat food and switching between sealing.

[0048] Workflow: During processing and production, the box body 11, feeding box 14, stud 15, wet food box 21, round plate 51, annular shell 53, sealing assembly 58, bottom cover 59, baffle 61, and dry food separator 571 are all integrally molded using a horizontal toggle injection molding machine. The disc shell 31 is transversely cut into two halves and injection molded separately. All the above components are made of PP hard plastic. The movable cylinder assembly 38 and flow regulating assembly 33 are prefabricated products. The rear end of the cylinder shell 381 is embedded into the cylindrical groove 36. The push plate 382 is located at the front end of the cylindrical groove 36. The rear end of the first spring 386 is attached to the... The inner side of the disc shell 31 near the front end of the cylindrical groove 36 is fitted together. Both third duckbill valves 37 are fixed to the front end of the cylindrical groove 36 with sealant. Then, the flow regulating component 33 is installed inside the screw hole 385 at the right end. The valve port of the first duckbill valve 333, which is aligned front to back, faces the same direction as the valve port of the third duckbill valve 37 at the right end. The second duckbill valve 24 is made of silicone. The flow regulating component 33 and the third duckbill valve 37 are made of rubber. Rotating the annular handle 331 causes the threaded cylinder 332 to be threaded into the inside of the screw hole 385, so that the first duckbill valve 333 fits against the front end of the push plate 382. The sealing block is installed in the same way. 39. The sealing block 39 is sealed to the push plate 382 by a rubber gasket. The silicone tube 42 is embedded inside the first built-in cylinder 34. The outer side of the silicone tube 42 is glued and fixed to the front position of the first built-in cylinder 34. The sealing plate 41 is threaded to the inner rear end of the disc shell 31, so that the sealing plate 41 squeezes the rear end of the silicone tube 42, thereby sealing the opening of the silicone tube 42. The silicone capsule 43 is placed inside the pressure regulating chamber 32. The upper half of the disc shell 31 and the lower half of the disc shell 31 are aligned vertically. The ultrasonic high-frequency vibration of the ultrasonic hot melt machine generates frictional heat on the contact surface of the two disc shells 31 to be bonded, promoting contact. The plastic sheet melts and solidifies rapidly to form a strong weld. The upper end of the silicone capsule 43 is fixed to the bottom end of the wet grain box 21 with a single-component room temperature vulcanizing RTV silicone adhesive. The wet grain box 21 and the disc shell 31 are aligned with their upper and lower axes and fixed with an ultrasonic hot melt machine. The mounting base 22 is fixed to the wet grain box 21 by hot melt. The second silicone pad 23 is embedded in the threaded nozzle 25. The second silicone pad 23 is tightly attached to the inside of the threaded nozzle 25 and its lower end is attached to the wet grain box 21. The wet grain box 21 is inverted and the threaded nozzle 25 is threadedly installed to the mounting base 22 until the threaded nozzle 25 is tightly attached to the second silicone pad 23.

[0049] The arc-shaped plate 52 and the annular shell 53 are integrated. The arc-shaped plate 52 and the circular plate 51 are heat-fused together. The extension column 581 is heat-fused to the circular plate 51 and is integrated with the first partition 582. The spiral strip 574 is embedded in the spiral groove 56, and its height is half the height of the spiral groove 56. The spiral strip 574 is located at the upper end of the spiral groove 56. The dry food separator 571 is inserted into the annular shell 53. The extension column 581 extends into the feed inlet 576. The top of the dry food separator 571 is attached to the bottom of the third silicone pad 585. The second partition 583 and the extension column 581 are heat-fused together. The outer side of the first silicone ring 575 is attached to the inner side of the annular shell 53. Finally, the dry food separator 571 and the spiral strip 574 are fixed together with glue. The baffle 61 is fitted onto the outside of the dry food divider 571, onto the outside of the annular shell 53 and the round plate 51. The second spring 62 and the rubber sleeve 63 are fitted onto the outside of the dry food divider 571. The elastic force of the second spring 62 causes the top of the baffle 61 to fit against the bottom of the disc shell 31. Dry cat food is poured into the dry food divider 571. The bottom cover 59 is then threaded into the inner thread groove 572 until the bottom of the second rubber pad 573 fits against the bottom cover 59. At this point, the wet food divider assembly 2 is placed inside the box body 11 with the wet food box 21 facing upwards. The top of the wet food box 21 is placed on the top of the retaining ring 12. The stud 15 is then threaded into the inner side of the spiral groove 13. The stud 15 presses the top of the wet food box 21 to secure it, allowing the wet food box 21 to shake inside the box body 11, thus completing the production process.

[0050] When feeding liquid cat food, rotate the feeding box 14 to move the stud 15 away from the spiral groove 13 on the box body 11, emptying the device inside the box body 11. Then, install the stud 15 onto the spiral groove 13 on the box body 11. The feeding trough 16 is the cavity for the cat to eat. The inclined surface 17 is set at an angle of 25 degrees, which is more in line with the pet's eating habits. Rotate the sealing block 39 to move it away from the push plate 382. At this time, the outside air will communicate with the inside of the cylindrical groove 36 on the left end through the first rubber pad 334 on the left end. The valve port of the first duckbill valve 333 faces the same direction as the valve port of the third duckbill valve 37 on the right end. The pressure regulating chamber 32 is threadedly connected to the screw hole 385. The first duckbill valve 333 seals between the annular handle 331 and the push plate 382. Pressing the push plate 382 backward causes the two cylindrical shells 381 to move backward. The push plate 382 slides inside the cylindrical groove 36, and at the same time, the push plate 382 compresses the first spring 386. With the sealing effect between the cylindrical shell 381 and the second inner cylinder 35 through the first rubber sealing ring 384, when the cylindrical shell 381 moves backward... The third duckbill valve 37 restricts gas flow to the rear-to-front. At this time, the gas inside the right-end cylindrical groove 36 flows out through the vent 383 from the first duckbill valve 333. Under the elastic thrust of the first spring 386, the cylinder shell 381 and push plate 382 reset. Due to the underpressure inside the right-end cylindrical groove 36, the gas inside the pressure regulating chamber 32 enters the right-end cylindrical groove 36 through the third duckbill valve 37. During this process, the pressure regulating chamber 32 experiences underpressure. To balance the pressure inside the pressure regulating chamber 32, the liquid grain storage bag 26... The liquid in the capsule flows into the silicone capsule 43 through the threaded nozzle 25 and the second duckbill valve 24. The silicone capsule 43 expands, and the rear end of the silicone tube 42 is blocked by the sealing plate 41, so the liquid cat food cannot overflow. An observation hole is provided on the inner side of the shell 31. The edge of the transparent acrylic plastic plate is fixed inside the observation hole with sealant to observe the expansion state of the silicone capsule 43. After the silicone capsule 43 is attached to the pressure regulating chamber 32, the amount of liquid cat food inside the silicone capsule 43 is 60ml to 80ml, which is suitable for a single meal of an adult cat.

[0051] Next, liquid cat food is fed into the silicone capsule 43. The flow rate of the liquid cat food is limited by the second duckbill valve 24, and the sealing plate 41 blocks the silicone tube 42. At this point, the liquid cat food inside the silicone capsule 43 cannot flow out. By operating the annular handle 331, both first rubber pads 334 are moved away from the push plate 382. Then, the sealing block 39 is operated, moving it away from the screw hole 385 at the left end. External air then enters the cylindrical groove 36 at the left end through the vent 383, and then enters the pressure regulating chamber 32 through the third duckbill valve 37 at the left end, thus balancing the air pressure inside the pressure regulating chamber 32. Finally, the sealing block 39 is installed inside the screw hole 385 at the right end. To seal the right-end ventilation duct 383, operate the annular handle 331 to install the other end of the threaded cylinder 332 inside the left-end threaded hole 385. The valve port of the first duckbill valve 333 should face the same direction as the valve port of the left-end third duckbill valve 37. At this point, align the silicone tube 42 towards the feeding trough 16. Operate the sealing plate 41 to detach it from the rear end of the disc shell 31, thus releasing the seal on the silicone tube 42. Through the elastic reset of the silicone capsule 43 and the silicone tube 42, the liquid cat food inside the silicone capsule 43 flows out through the silicone tube 42 and drips into the feeding trough 16. During this process, external air will enter the left-end ventilation duct 383 through the first duckbill valve 333 and... Inside the cylindrical groove 36, air enters the pressure regulating chamber 32 through the third duckbill valve 37 at the left end to continuously relieve the air pressure inside the pressure regulating chamber 32. Simultaneously, the aforementioned operating principle presses the push plate 382. When the push plate 382 moves backward, the first duckbill valve 333 restricts the airflow direction, pushing the gas inside the left cylindrical groove 36 through the third duckbill valve 37 into the pressure regulating chamber 32. When the push plate 382 moves forward, the third duckbill valve 37 further restricts the airflow, reducing the air pressure inside the cylindrical groove 36. To relieve the air pressure inside the left cylindrical groove 36, external air enters the cylindrical groove 36 through the first duckbill valve 333, again pressuring the push plate 382. Press 82 repeatedly, and the gas volume inside the pressure regulating chamber 32 gradually increases. Through the pressure of the gas, the liquid cat food remaining inside the silicone capsule 43 and silicone tube 42 is squeezed out until the silicone capsule 43 and silicone tube 42 are deflated. Then, the sealing plate 41 seals the silicone tube 42, and the sealing block 39 and flow regulating component 33 are reset for easy reuse. This feeding method changes the traditional pouring feeding method. During multiple feedings, there will be no air intrusion into the packaging due to volume gaps, which greatly reduces the risk of cat food oxidation and spoilage, ensures the freshness of the remaining cat food for secondary consumption, and significantly reduces the probability of cats experiencing gastrointestinal discomfort and other health problems caused by eating spoiled cat food.

[0052] When feeding dry cat food, press the rubber sleeve 63 to make the inner side of the rubber sleeve 63 fit tightly against the outer side of the dry food divider 571. At the same time, rotate the rubber sleeve 63. The rubber sleeve 63 drives the dry food divider 571 to rotate through friction. Since the spiral strip 574 is threadedly connected to the spiral groove 56, it will move up and down inside the annular shell 53 during the rotation of the dry food divider 571. When the upper end of the spiral strip 574 fits tightly against the upper end of the spiral groove 56, the dry food divider 571 cannot rotate. At this time, the feed inlet 576 is located between the first partition 582 and the second partition 583. Turn the dry food divider 571 over and let the liquid food storage bag 26 face towards the liquid food storage bag 26. By shaking the dry food divider 571 downwards, the dry cat food stored inside will pass through the feed inlet 576 between the second partition 583 and the dry food divider 571, and then through the gap between the first partition 582 and the dry food divider 571 into the baffle 61. The baffle 61 is made of polyethylene terephthalate and is a highly transparent food contact plastic material. The amount of dry cat food inside the baffle 61 can be observed through the gaps between the desiccant sheets 65. When the amount of dry cat food is about to touch the first partition 582, the dry food divider 571 is rotated to reset. Dry cat food enters the dry food divider 571 through the feeding port 576 until the third silicone pad 585 contacts the dry food divider 571, thus sealing the feeding port 576. The operating stop cylinder 61 moves towards the bottom cover 59, sliding outside the dry food divider 571. The stop cylinder 61 compresses the second spring 62, causing the cat food between the circular plate 51 and the dry food divider 571 to fall into the feeding trough 16 through the two curved plates 52. After feeding, the stop cylinder 61 is released, and the second spring 62 pushes it back to its original position. At this point, the end of the stop cylinder 61 is in contact with the disc shell 31, and the inner side of the stop cylinder 61 is in contact with the outer side of the second silicone ring 54 and the... A silicone ring 575 is attached to the outside, and at this time the space between the round plate 51 and the dry food divider 571 is a sealed cavity. The inside of the sealed cavity is dried by the desiccant sheet 65 to facilitate the feeding of dry food again. The desiccant sheet 65 can be replaced within one week. Based on the above principle, the dry cat food is set up with an isolated dry and sealed cavity when feeding. Before feeding, the dry cat food stored in the dry food will not come into direct contact with the air. At the same time, it can ensure the dry environment inside the dry cat food storage. During the feeding process, the cavity storing the dry cat food is sealed. After feeding, the isolated dry and sealed cavity is dried again to facilitate the feeding of dry cat food again, extend the shelf life of dry cat food, and improve the safety of eating dry cat food.

[0053] During cleaning, operate the liquid grain storage bag 26 to detach the threaded nozzle 25 from the mounting base 22, operate the bottom cover 59 to move it away from the dry grain separator box 571, and push the rubber sleeve 63 and the second spring 62 out of the dry grain separator box 571. At this time, the baffle 61 can be directly removed from the dry grain separator box 571, so that the adhesive desiccant sheet 65 can be torn off and replaced. Operate the dry grain separator box 571 in the same way as above to release the blockage of the feed inlet 576. Rinse the inner wall of the dry grain separator box 571 and the baffle 61 with pure water. The pure water flows through the feed inlet 576 to clean the sealing assembly 5. 8. Clean the inside of the feed inlet 576, thoroughly rinse the round plate 51 and the annular shell 53, remove the sealing plate 41, and then insert the spray nozzle into the mounting base 22. Rinse the mounting base 22, the second duckbill valve 24, the silicone capsule 43, and the silicone tube 42 by aligning the air outlet of the hot air blower with the mounting base 22, and dry the mounting base 22, the second duckbill valve 24, the silicone capsule 43, and the silicone tube 42 for reuse. In this way, after the cat food is used up, only the cat food needs to be replaced and refilled, without the need to replace the packaging structure, reducing economic investment and improving market competitiveness.

The flow regulating assembly (33) is installed in the right end screw hole (385) to align the first duckbill valve (333) front and back. The valve port faces the same direction as the valve port of the third duckbill valve (37) on the right end. Rotate the ring handle (331) to make the threaded cylinder (332) threadedly connected to the threaded hole (385). The first duckbill valve (333) fits against the front end of the push plate (382). The sealing block (39) is sealed with the push plate (382) through the rubber pad. The outer side of the silicone tube (42) is glued and fixed to the front of the first built-in cylinder (34). The sealing plate (41) is threaded to the inner side of the rear end of the disc shell (31) and squeezes the rear end of the silicone tube (42). The two halves of the disc shell (31) are aligned and welded and fixed. The upper end of the silicone capsule (43) is fixed to the bottom end of the wet grain box (21). The mounting seat (22) is heat-fused and fixed to the wet grain box (21). The second silicone pad (23) is embedded in the threaded nozzle (25) and closely fits its inner side and the wet grain box (21) to ensure that the threaded nozzle (25) fits against the second silicone pad (23). Step 2: Assembly and Dry Cat Food Filling. The arc plate (52) and the annular shell (53) are an integral structure, and are fixed to the round plate (51) by heat fusion. The extension column (581) is heat fused to the round plate (51) and is integral with the first partition (582). The spiral strip (574) is embedded in the spiral groove (56). The dry food separator (571) is inserted into the annular shell (53) and extends to the feed inlet (576). Its top end is attached to the bottom end of the third silicone pad (585). The second partition (583) is heat fused to the extension column (581). The outer side of the first silicone ring (575) is attached to the inner side of the annular shell (53). The dry food separator (571) is fixed to the spiral strip (574). The baffle ( 61) The dry food divider box (571) is fitted on the outside of the annular shell (53) and the round plate (51). The second spring (62) and the rubber sleeve (63) are fitted on the outside of the dry food divider box (571). The second spring (62) makes the top of the baffle (61) fit against the bottom of the disc shell (31). Dry cat food is put into the dry food divider box (571). The bottom cover (59) is threaded to the inner thread groove (572) until the second rubber pad (573) fits against the bottom cover (59). The wet food divider assembly (2) is placed in the box body (11) with the wet food box (21) facing upward. The wet food box (21) is placed on the top of the baffle ring (12). The stud (15) is threaded to the spiral groove (13) and presses the top of the wet food box (21) firmly. Step 3: Liquid cat food feeding quantity control, separate the stud (15) and the spiral groove (13), take out the device inside the box (11) and reset the stud (15), rotate the sealing block (39) to make it disengage from the push plate (382), external air enters the cylindrical groove (36) at the left end through the first rubber pad (334) at the left end, at this time the valve ports of the first duckbill valve (333) and the third duckbill valve (37) at the right end are in the same direction, the pressure regulating chamber (32) is threaded to the screw hole (385), the first duckbill valve (333) seals the gap between the ring handle (331) and the push plate (382), press the push plate (382) backward to drive the cylinder shell (3 81) Move and squeeze the first spring (386), the third duckbill valve (37) blocks the airflow, the gas in the right end cylindrical groove (36) is discharged from the first duckbill valve (333) through the ventilation channel (383), and the cylinder shell (381) and push plate (382) are reset by the elastic force of the first spring (386), so that the cylindrical groove (36) and the pressure regulating chamber (32) are under-pressured in sequence. The liquid cat food in the liquid storage bag (26) flows into the silicone capsule (43) through the threaded nozzle (25) and the second duckbill valve (24) to expand it. When the silicone capsule (43) fits the pressure regulating chamber (32), the dosage is controlled to be 60ml-80ml. Step 4: When dispensing liquid cat food, the second duckbill valve (24) restricts the flow rate, the sealing plate (41) keeps the silicone tube (42) sealed, separate the two first rubber pads (334) from the push plate (382), and the sealing block (39) from the left end screw hole (385) to allow external air to enter the pressure regulating chamber (32) to balance the air pressure. Install the sealing block (39) into the right end screw hole (385) and the threaded cylinder (332) into the left end screw hole (385), so that the first duckbill valve (333) and the left end first... With the three duckbill valves (37) facing the same direction, adjust the silicone tube (42) to face the feeding trough (16), remove the sealing plate (41), and use the elastic return force of the silicone capsule (43) and silicone tube (42) to make the liquid cat food drip through the silicone tube (42) into the feeding trough (16). Press the push plate (382) to circulate and push the airflow to empty the silicone capsule (43) and silicone tube (42). Finally, reset the sealing plate (41) to seal the silicone tube (42), and the sealing block (39) and threaded cylinder (332) are returned to their positions. Step 5: When feeding dry cat food, press and rotate the rubber sleeve (63) to drive the dry food divider box (571) to rotate and rise to the limit inside the annular shell (53). Flip the dry food divider box (571) so that the liquid food storage bag (26) faces down and shakes. The dry cat food enters the baffle (61). When the dry cat food is about to contact the first partition (582), reset the dry food divider box (571). Excess cat food falls back through the feed inlet (576). The third silicone pad (585) adheres to the dry food divider box (571). Move the baffle (61) to squeeze the second spring (62) and then release it. The elastic force of the second spring (62) makes the baffle (61) adhere to the outer side of the disc shell (31) and the second silicone ring (54) and the first silicone ring (575) to form a sealed cavity. After drying with the desiccant sheet (65), the feeding preparation is completed. Step Six: Clean and maintain the device. Separate the threaded nozzle (25) from the mounting base (22), the bottom cover (59) from the dry food separator box (571), remove the rubber sleeve (63), the second spring (62), the baffle (61) and replace the desiccant sheet (65). Operate the dry food separator box (571) according to the principle of Step Three to release the blockage of the feed inlet (576). Rinse the dry food separator box (571), baffle (61), sealing assembly (58), feed inlet (576), round plate (51) and annular shell (53) with pure water. Remove the sealing plate (41). Insert the water spray nozzle into the mounting base (22) to rinse the mounting base (22), the second duckbill valve (24), the silicone capsule (43) and the silicone tube (42). Then dry the above components with a hot air blower.
