Description

Technical Field

[0001] This invention relates to the field of food can technology, specifically to a food can with controllable dispensing capacity and odor-proof design. Background Technology

[0002] In the field of food production, processing and storage, food cans, as core packaging containers, play an important role in protecting food quality, extending shelf life and improving ease of use. They are widely used in the packaging and distribution of various foods such as condiments, dried goods, sauces, and tea. However, in the storage of some powdered foods, conventional food cans cannot effectively control the amount of material dispensed, making it necessary to use additional tools for quantitative dispensing, which is complicated.

[0003] Prior art (Chinese Patent No. CN221643194U, Publication Date: 2024-09-03) discloses a multifunctional food can, including a top cover, a can body, and a bottom cover connected in sequence. The bottom cover is provided with an opening assembly for removing contents stored at the bottom of the can body. The opening assembly includes a central hole formed in the middle of the bottom cover, and a pressure cap for sealing the central hole is provided at the central hole. A thin film for sealing the central hole is provided at the top opening of the central hole, and the thin film is located above the bottom cover. Compared with the prior art, the opening assembly provided on the bottom cover, including a central hole in the middle of the bottom cover, and a pressure cap for sealing the central hole, provides a more efficient and convenient method. The cap has a central hole and a thin film covering it. This film prevents powdered substances like milk powder from leaking out. To remove residue from the bottom of the can, simply pry the cap out of the central hole and tear off the separator. This cleans the bottom of the can and avoids waste. Existing technology (Chinese Patent No. CN214453829U, published on 2021-10-22) discloses a powder container for easy dispensing, belonging to the field of can body technology. It includes a can body with an inlet and an outlet, and the can body is equipped with support legs. The inlet is equipped with a valve, and the outlet is equipped with an anti-clogging device to prevent powder blockage. The tank body contains a movable frame and a drive device for moving the frame up and down along the inner wall of the tank. A brush head is fixed to the movable frame, contacting the inner wall of the tank. The outlet is equipped with a sealing head to prevent powder from flying around, and the sealing head is equipped with a valve. This effectively prevents powder from adhering to the inner wall of the tank, preventing waste, facilitating thorough cleaning of the inner wall, ensuring high powder discharge efficiency, avoiding blockage of the outlet, and is suitable for all tanks storing powder. (Prior technology (Announcement No.: CN220181637U, Publication Date: 2023-12-1)) Chinese Patent No. 5 discloses a powder hopper for easy material handling, comprising a hopper body, a dust collector installed on the top of the hopper body, a feeding pipe installed on the hopper body, and a feeding assembly installed at the bottom of the pipe body. The feeding assembly includes a conveying channel, a rotating shaft, a spiral arc plate, and a drive motor. The conveying channel is provided with an inlet and an outlet. The conveying channel is connected to the bottom of the hopper body, and the inlet communicates with the outlet of the hopper body. The rotating shaft is rotatably connected inside the conveying channel, the spiral arc plate is connected to the rotating shaft, and the drive motor is connected to one end of the conveying channel and coaxially connected to the rotating shaft.

[0004] Existing food cans cannot avoid bridging during the feeding process when storing powders, which makes it impossible to accurately control the amount of powder and to fully dispense it. This requires manually shaking the can to assist in dispensing, which is inconvenient and has certain defects in use. Summary of the Invention

[0005] The purpose of this invention is to provide a food can with controllable dispensing and odor-proof design, in order to solve the problem mentioned in the background art that current food cans on the market cannot avoid bridging during the dispensing process when storing powder, thus making it impossible to accurately control the amount of powder and fully dispense it.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a controllable dispensing, odor-resistant food can, comprising a can body, a can lid sealed at the top of the can body, and a sealing ring connecting the can body and the can lid; a support leg fixedly installed at the lower part of the can body, and a receiving tray fixedly installed on the support leg; a dispensing pipe provided at the lower end of the can body, a quantitative dispensing device provided on the inner side of the dispensing pipe; a control sleeve slidably fitted on the outer side of the can body, and a movable connecting rod fixedly connected to the lower end of the control sleeve; and the movable connecting rod and the quantitative dispensing device... A drive mechanism is provided between the devices, and the quantitative feeder is driven by the drive mechanism to quantitatively feed the material during the adjustment of the sliding sleeve lifting. A drain rod is installed on the inner side of the tank, and a rotating seat is rotatably installed on the inner side of the upper part of the tank. A transmission seat is fixedly installed on the inner side of the rotating seat. The drain rod passes through the transmission seat during lifting, and a transmission component is provided between the drain rod and the transmission seat. During the adjustment of the drain rod lifting, the transmission component drives the transmission seat to rotate. An elastic rubber part is sealed and fixedly connected between the rotating seat and the lower part of the tank.

[0007] Preferably, the quantitative feeder includes a central shaft rotatably mounted inside the feed tube, and four partitions are fixedly mounted at equal angles on the outer side of the central shaft. The partitions are sealed against the inner wall of the feed tube, and the central shaft drives the partitions to rotate to achieve quantitative feeding.

[0008] Preferably, the end of the central shaft of the quantitative feeder is connected to a gear via a one-way bearing, the drive mechanism includes a rack fixedly installed on the outer side of the lower end of the movable connecting rod, and the rack and gear are meshed together, and a spring is fixedly connected between the movable connecting rod and the frame on the outer side of the feed tube.

[0009] Preferably, during the downward movement of the rack, the gear and the metering feeder are rotated, and the single rotation angle of the metering feeder is 90°.

[0010] Preferably, the lower part of the control sleeve is made of magnetic material, and a striking plate is uniformly and elastically rotatably installed on the lower outer side of the tank body. The end of the striking plate near the feed pipe is attached to the outer wall of the tank body, and a first magnetic plate is fixedly installed on the outer side of the end of the striking plate away from the feed pipe. The magnetic poles of the opposite surfaces of the first magnetic plate and the magnetic material in the lower part of the control sleeve are opposite. During the rotation and reset process, the striking plate strikes the lower outer side of the tank body.

[0011] Preferably, the unblocking rod and the tank are coaxially arranged, and the lower end of the unblocking rod is located inside the feed pipe. During the rotation of the quantitative feeder, the unblocking rod is pushed up and adjusted by the partition.

[0012] Preferably, a fixing frame is fixedly installed on the upper inner side of the tank, and the fixing frame and the upper part of the unblocking rod are slidably connected.

[0013] Preferably, the upper outer side of the unclogging rod is provided with a spiral guide groove, and a ball bearing is embedded in the inner wall of the transmission seat. During the adjustment of the unclogging rod's lifting and lowering, the ball bearing slides along the guide groove to drive the transmission seat to rotate.

[0014] Preferably, the rotating seat and the elastic rubber part are coaxially arranged, and the elastic rubber part is cylindrical. During the rotation of the rotating seat, the upper and lower ends of the elastic rubber part are driven to rotate relative to each other, and the elastic rubber part is twisted during the relative rotation of the upper and lower ends.

[0015] Preferably, a third magnetic sheet is uniformly fixedly connected to the outer wall of the middle part of the elastic rubber part, and a second magnetic sheet is uniformly fixedly connected to the middle part of the can body. The second and third magnetic sheets are positioned correspondingly and their magnetic poles are opposite. A flexible scraper is symmetrically fixedly installed on the outer side of the unblocking rod, and the scraper is attached to the outer side of the elastic rubber part.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the controllable dispensing anti-odor food can does not require opening the lid to take out the material, can effectively seal and preserve the material, and can conveniently control the dispensing of the material, making the dispensing accurate and convenient. The specific details are as follows; 1. Equipped with a quantitative feeder and gears, the sliding sleeve is pushed down to control the sliding sleeve, which drives the rack to move down synchronously via the movable connecting rod. This allows the rack to drive the gear to rotate through meshing, and the gear will drive the quantitative feeder to rotate synchronously through a one-way bearing. During the 90° rotation of the quantitative feeder, the powder between the adjacent partitions will enter the lower part of the feeding pipe, achieving controlled feeding. With the receiving tray and guidance, it is easy to pick up. 2. Equipped with a striking plate and a clearing rod, as the control sleeve moves downward, the magnetic material at its lower part approaches the first magnetic piece on the striking plate, causing the striking plate to rotate elastically under the action of magnetic force. When the control sleeve moves upward to reset, the striking plate will rotate elastically to reset, thereby striking the lower end of the tank. The vibration promotes the collapse of the powder and avoids bridging. At the same time, as the quantitative feeder rotates, it can push the clearing rod to extend and retract, thereby assisting in clearing and further ensuring the stability of the feeding. 3. It is equipped with a rotating seat and elastic rubber parts. As the unclogging rod is raised and lowered, the ball will slide along the guide groove, thereby driving the rotating seat to rotate. The rotating seat will cause the elastic rubber parts to twist, thereby reducing the adhesion between the powder and the elastic rubber parts and the powder residue. At the same time, during the twisting process of the elastic rubber parts, the distance between the second magnetic sheet and the third magnetic sheet gradually increases, so that the elastic rubber parts will elastically vibrate synchronously during the twisting process, further improving the powder peeling effect.

[0019] Example 1: Existing food cans require opening and manual removal of materials, resulting in prolonged exposure of the powder to air, which reduces sealing and makes it prone to cross-contamination of flavors. To solve this technical problem, this example discloses the following technical content. Please refer to [link / reference]. Figures 1-4 and Figure 6 As shown; A controllable dispensing, odor-resistant food can includes a can body 1, a can lid 2 sealed on the top of the can body 1, and a sealing ring 3 connecting the can body 1 and the can lid 2. A support leg 4 is fixedly installed on the lower part of the can body 1, and a receiving tray 5 is fixedly installed on the support leg 4. A feeding pipe 6 is provided at the lower end of the can body 1, and a quantitative feeder 7 is provided on the inner side of the feeding pipe 6. A control sleeve 9 is slidably sleeved on the outer side of the can body 1, and a movable connecting rod 10 is fixedly connected to the lower end of the control sleeve 9. A driving mechanism is provided between the movable connecting rod 10 and the quantitative feeder 7. During the lifting and adjusting of the control sleeve 9, the quantitative feeder 7 is driven by the driving mechanism to dispense quantitatively.

[0020] The quantitative feeder 7 includes a central shaft rotatably mounted inside the feed tube 6, and four partitions are fixedly mounted at equal angles on the outer side of the central shaft. The partitions are sealed against the inner wall of the feed tube 6. The central shaft drives the partitions to rotate to achieve quantitative feeding. The end of the central shaft of the quantitative feeder 7 is connected to a gear 8 through a one-way bearing. The drive mechanism includes a rack 11 fixedly mounted on the outer side of the lower end of the movable connecting rod 10. The rack 11 and the gear 8 are meshed. A spring is fixedly connected between the movable connecting rod 10 and the frame on the outer side of the feed tube 6. During the downward movement of the rack 11, the gear 8 and the quantitative feeder 7 are driven to rotate. The single rotation angle of the quantitative feeder 7 is 90°.

[0021] By pushing down the control sleeve 9, the control sleeve 9 drives the rack 11 to move down synchronously through the movable connecting rod 10. The rack 11 drives the gear 8 to rotate through meshing. The gear 8 drives the quantitative feeder 7 to rotate synchronously through the one-way bearing. During the rotation of the quantitative feeder 7 by 90°, the powder between the adjacent partitions will enter the lower part of the feeding pipe 6 to achieve controlled feeding. With the receiving tray 5 receiving and guiding, it is easy to pick up without opening the can lid 2 to pick up the powder.

[0022] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Existing food cans are inconvenient for precise control of powder dispensing, causing powder to easily adhere to the can body. To further solve this technical problem, this example discloses the following technical content, such as... Figures 5-10 As shown; A drain rod 15 is installed on the inner side of the tank body 1, and a rotating seat 16 is rotatably installed on the upper inner side of the tank body 1. A transmission seat 17 is fixedly installed on the inner side of the rotating seat 16. The drain rod 15 passes through the transmission seat 17, and a transmission component is provided between the drain rod 15 and the transmission seat 17. During the adjustment of the drain rod 15, the transmission component drives the transmission seat 17 to rotate. An elastic rubber part 20 is sealed and fixedly connected between the rotating seat 16 and the lower part of the tank body 1.

[0023] The lower part of the control sleeve 9 is made of magnetic material. A striking plate 12 is uniformly and elastically mounted on the outer side of the lower part of the tank body 1. The end of the striking plate 12 near the feed pipe 6 is attached to the outer wall of the tank body 1, and a first magnetic plate 13 is fixedly mounted on the outer side of the end of the striking plate 12 away from the feed pipe 6. The magnetic poles of the opposite surfaces of the first magnetic plate 13 and the magnetic material at the lower part of the control sleeve 9 are opposite. During the rotation and reset process, the striking plate 12 strikes the outer side of the lower part of the tank body 1. The unblocking rod 15 is coaxially arranged with the tank body 1, and the lower end of the unblocking rod 15 is located inside the feed pipe 6. During the rotation of the quantitative feeder 7, the unblocking rod 15 is pushed upwards and adjusted by a partition. A fixing frame 14 is fixedly mounted on the inner side of the upper part of the tank body 1, and the fixing frame 14 is slidably connected to the upper part of the unblocking rod 15. A spiral guide is provided on the outer side of the upper part of the unblocking rod 15. The groove 19 and the inner wall of the transmission seat 17 are embedded with ball bearings 18. During the lifting and lowering adjustment of the unclogging rod 15, the ball bearings 18 slide along the guide groove 19 to drive the transmission seat 17 to rotate. The rotating seat 16 and the elastic rubber part 20 are coaxially arranged. The elastic rubber part 20 is cylindrical. During the rotation of the rotating seat 16, the upper and lower ends of the elastic rubber part 20 are driven to rotate relative to each other. At the same time, the elastic rubber part 20 is twisted during the relative rotation of the upper and lower ends. The outer wall of the middle part of the elastic rubber part 20 is uniformly fixedly connected with a third magnetic sheet 22. The middle position of the tank 1 is uniformly fixedly connected with a second magnetic sheet 21. The second magnetic sheet 21 and the third magnetic sheet 22 are positioned correspondingly and their magnetic poles are opposite. The outer side of the unclogging rod 15 is symmetrically fixedly installed with a flexible scraper 23. The scraper 23 is attached to the outer side of the elastic rubber part 20.

[0024] As the control sleeve 9 moves downward, the magnetic material at its lower part approaches the first magnetic piece 13 on the striking piece 12, causing the striking piece 12 to rotate elastically under magnetic force. When the control sleeve 9 moves upward to reset, the striking piece 12 will rotate elastically to reset, thereby striking the lower end of the can 1. The vibration promotes the collapse of the powder and avoids bridging. At the same time, as the metering feeder 7 rotates, it can push the unblocking rod 15 to extend and retract, thereby assisting in unblocking and further ensuring the stability of the feeding. As the unblocking rod 15 is raised and lowered, the ball bearing 18 slides along the guide groove 19, thereby driving the rotating seat 16 to rotate. The rotating seat 16 will cause the elastic rubber part 20 to twist, thereby reducing the adhesion between the powder and the elastic rubber part 20 and the powder residue. At the same time, during the twisting process of the elastic rubber part 20, the distance between the second magnetic piece 21 and the third magnetic piece 22 gradually increases, so that the elastic rubber part 20 will elastically vibrate synchronously during the twisting process, further improving the powder peeling effect.
