Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to a split tank structure. Background Art

[0002] Currently, for existing infant milk powder cans, milk powder is scooped out after opening. There are the following problems: 1. The amount of milk powder scooped out is not accurate. Especially when it comes to one-third or two-thirds of a scoop, since the spoon has no scale, it is impossible to judge whether the scooped amount is accurate, which affects the digestion and absorption of milk powder by infants; 2. Since the milk powder can needs to be opened every time milk is made, the milk powder inside is prone to getting damp and caking, affecting the quality of the milk powder; 3. When scooping out milk powder with a milk powder spoon, people's hands have to reach into the milk powder can, which easily contaminates the milk powder and thus affects the health of infants; 4. When scooping out milk powder with a milk powder spoon, when there is not much milk powder left in the can, the milk powder spoon cannot scoop it out, resulting in the waste of the milk powder at the bottom of the can.

[0003] In view of this, the applicant previously applied for a utility model patent solution for a milk powder can structure to solve the above problems. This utility model patent was publicly authorized on July 30, 2024, with the publication number CN221439122U. By using the powder outlet nozzle in this solution, the powder outlet channel can discharge milk powder quantitatively, making the milk powder not easily get damp and caked and not easily get contaminated. However, for the integrated milk powder can in this solution, due to the installation of the collection trough and the powder outlet nozzle, the volume is larger than that of milk powder cans on the market, thus increasing the manufacturing cost of the product and also increasing the packaging and transportation costs. Moreover, due to the integrated structure, when the milk powder in the can is used up, the milk powder can is discarded, and the collection trough and the powder outlet nozzle are also discarded simultaneously, which is not conducive to the recycling of resources. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a split tank structure, which has the advantages of reducing manufacturing, packaging and transportation costs. At the same time, it plays a role in recycling, energy conservation and environmental protection.

[0005] To achieve the above object, the solution of the utility model is:

[0006] A split tank structure includes a tank body, a collection funnel and a quantitative powder outlet nozzle;

[0007] The top of the tank body has an opening communicating with the inside of the tank body, and the opening is sealed with a tank cover or detachably connected to the collection funnel;

[0008] The funnel inlet of the collection funnel is detachably connected to the opening of the tank body, and the funnel outlet of the collection funnel is detachably connected to the quantitative powder outlet nozzle;

[0009] The quantitative powder outlet nozzle is used for quantitatively outputting the contents stored in the tank body.

[0010] Further, one end of the powder metering nozzle is detachably connected to the outlet of the funnel. The other end of the powder metering nozzle is the powder outlet, and there is a powder outlet channel between the powder inlet and the powder outlet. At least two pins are arranged between the powder inlet and the powder outlet of the powder metering nozzle. The pin close to the powder outlet is a closed pin, and the other pins are metering pins. Each pin is arranged in a staggered manner along the powder outlet direction of the powder outlet channel. The metering area between the metering pin and the closed pin is a preset capacity. The pins are used to actively open and close the connection between the powder outlet channel and the collecting funnel or the outside.

[0011] Further, the powder metering nozzle includes a powder outlet main body and two collecting parts arranged at both ends of the powder outlet main body. The powder outlet main body is in the shape of a rectangular hollow tube. There are collecting grooves in the two collecting parts, and the collecting outlets at the outer ends of the collecting grooves far from the powder outlet main body are designed to be tapered. The collecting outlets of the two collecting parts are respectively communicated with the powder inlet and the powder outlet.

[0012] Further, the outer ends of the two collecting parts are respectively connected to a hollow powder inlet part and a powder outlet part. The powder inlet part is used for threaded connection with the outlet of the funnel, and the outer end of the powder inlet part is the powder inlet. The outer end of the powder outlet part is the powder outlet.

[0013] Further, a powder outlet cover is threadedly connected to the outer end of the powder outlet part. The opening of the tank body is threadedly connected to both the funnel inlet of the collecting funnel and the tank cover.

[0014] Further, the pin includes an internally and externally connected pin partition part, a pin operation part, and a sealing flange plate. The pin partition part is limited in the powder outlet channel and moves perpendicular to the powder outlet direction. The pin operation part extends out from the side wall opening of the main body part of the powder metering nozzle. The pin operation part is used for the user to push and pull to drive the pin partition part to move to open and close the powder outlet channel.

[0015] An annular sealing sunk groove is arranged on the outer periphery of the side wall opening. A sealing flange plate protrudes around the connection between the pin operation part and the pin partition part. When the pin partition part completely closes the powder outlet channel, the sealing flange plate is fitted into the sealing sunk groove. The sealing flange plate is used to fit into the sealing sunk groove to ensure the airtightness of the tank body.

[0016] Further, the pin partition part is arranged to slide left and right. Sliding grooves are recessed on the inner walls of the other three sides of the powder outlet channel except the side wall opening. Both the front and rear sides of the pin partition part are partially embedded in the sliding grooves, and anti-detachment blocks protrude towards the inside of the sliding grooves respectively at the end sides of the front and rear sides far from the pin operation part. The two sides of the side wall opening have limiting parts for preventing the anti-detachment blocks from detaching from the sliding grooves in the powder outlet channel. The pin operation parts of adjacent pins are respectively located on the outer sides of different sides of the powder metering nozzle.

[0017] Further, there are multiple powder metering nozzles, and each powder metering nozzle is provided with two pins; the distances between the metering pins and the closing pins on each powder metering nozzle are different, so that there are different preset capacities between the metering pins and the closing pins of each powder metering nozzle.

[0018] Further, the powder metering nozzle and the collecting funnel are made of transparent materials.

[0019] Further, it further includes a bracket; the top of the tank body is the opening; the tank body is removably suspended upside down on the bracket.

[0020] After adopting the above technical solution, on the premise that this solution can conveniently obtain the quantitative content in the tank body and has the advantages of avoiding moisture absorption and pollution of the content, by setting the collecting funnel and the powder metering nozzle as a split structure with the tank body, one collecting funnel and one powder metering nozzle can be adapted to multiple tank bodies. After the collecting funnel and the powder metering nozzle are cleaned and disinfected, they can be reused. It is not necessary for each tank body to be equipped with a collecting funnel and a powder metering nozzle, which can reduce the manufacturing cost and packaging cost of the product, enhance the practicability, thereby realizing recycling, saving social costs, and greatly improving the product competitiveness; at the same time, due to the split type, users can freely choose powder metering nozzles with different quantities, and the preparation can be completed with one operation, greatly reducing the workload of users.

Detailed implementation mode

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0031] As Figures 1 to 4 shown, a split tank body structure of the present utility model includes a tank body 1, a collecting funnel 2 and a quantitative powder outlet nozzle 3.

[0032] The top of the tank body 1 has an opening 11 communicating with the inside of the tank body 1 (the tank body 1 shown in the figure is a schematic illustration with the top opening 11 facing downwards). Taking the storage of milk powder in the tank body 1 as an example for illustration, of course, other powdery contents can also be stored, such as protein powder, etc.

[0033] The opening 11 can be sealed with a tank body cover 12 or detachably connected to the collecting funnel 2.

[0034] The funnel inlet 21 of the collecting funnel 2 is detachably connected to the opening 11 of the tank body 1, and the funnel outlet 22 of the collecting funnel 2 is detachably connected to the quantitative powder outlet nozzle 3; the collecting funnel 2 is provided to facilitate the collection and outflow of the milk powder content in the tank body 1; and the quantitative powder outlet nozzle 3 is used to quantitatively output the milk powder content stored in the tank body 1.

[0035] Thus, by setting the collecting funnel 2 and the metering powder outlet nozzle 3 as a separable structure from the tank body 1, one collecting funnel 2 and one metering powder outlet nozzle 3 can be adapted to multiple tank bodies 1. At the same time, the collecting funnel 2 and the metering powder outlet nozzle 3 can be reused after cleaning and disinfection, without each tank body 1 being equipped with a collecting funnel 2 and a metering powder outlet nozzle 3, which can reduce the manufacturing cost and packaging volume of the product, enhance practicability, achieve recycling, save social costs, and greatly improve the product competitiveness. Moreover, the tank body 1 can adopt the structure of an existing milk powder can, and the funnel opening 11 of the collecting funnel 2 can be separately connected and adapted to the milk powder can to reduce the transformation cost of the tank body 1.

[0036] Refer to again Figures 4 to 6 , one end of the metering powder outlet nozzle 3, the powder inlet 31, is detachably connected to the funnel outlet 22. The other end of the metering powder outlet nozzle 3 is the powder outlet 32, and between the powder inlet 31 and the powder outlet 32 is a powder outlet passage 33; at least two pins 34 are provided between the powder inlet 31 and the powder outlet 32 of the metering powder outlet nozzle 3. In this embodiment, taking two pins 34 as an example, the pin 34 close to the powder outlet 32 is the closed pin 34a, and the pin 34 close to the powder inlet 31 is the metering pin 34b. Of course, multiple metering pins 34b can also be set, and the setting of multiple metering pins 34b can refer to the existing technology.

[0037] As Figure 4 , the two pins 34 can be arranged in a staggered manner along the powder outlet direction of the powder outlet passage 33, and the metering area 35 between the metering pin 34b and the closed pin 34a is a preset capacity; the pins 34 are used to actively open and close the connection between the powder outlet passage 33 and the collecting funnel 2 or the outside.

[0038] Thus, by closing the closed pin 34a close to the powder outlet 32 and opening the metering pin 34b close to the powder inlet 31, the milk powder in the collecting funnel 2 can flow in and fill the metering area 35. Then, close the metering pin 34b close to the powder inlet 31 and open the closed pin 34a close to the powder outlet 32, so that the milk powder in the metering area 35 flows out into a milk powder bottle (not shown in the figure), and in this way, a precise amount of milk powder can be obtained.

[0039] Specifically, refer to again Figure 7 , the pin 34 can include an internally and externally connected pin partition part 341, a pin operation part 342, and a sealing flange plate 343. The pin partition part 341 is limited in the powder outlet passage 33 and moves perpendicularly to the powder outlet direction. The pin operation part 342 extends from the side wall opening 361 of the main body part of the metering powder outlet nozzle 3, and the pin operation part 342 is used for the user to push and pull to drive the pin partition part 341 to move to open and close the powder outlet passage 33;

[0040] An annular sealing groove 362 is provided on the outer periphery of the side wall opening 361. A sealing flange plate 343 protrudes at the connection between the plug operation portion 342 and the plug partition portion 341. When the plug partition portion 341 completely closes the powder outlet passage 33, the sealing flange plate 343 is fitted into the sealing groove 362. The sealing flange plate 343 is used to fit the sealing groove 362 to ensure the airtightness of the tank body 1 and prevent milk powder from getting damp.

[0041] In this embodiment, the plug partition portion 341 is slidably arranged left and right; sliding grooves 331 are recessed in the inner walls of the other three sides of the powder outlet passage 33 except for the side wall opening 361. Both the front and rear sides of the plug partition portion 341 are partially fitted into the sliding grooves 331, and anti-detachment blocks 3411 protrude towards the inside of the sliding grooves 331 at the end sides of the front and rear sides away from the plug operation portion 342; limiting portions 3611 for preventing the anti-detachment blocks 3411 from detaching from the sliding grooves 331 in the powder outlet passage 33 are provided on both sides of the side wall opening 361; by providing the sliding grooves 331, and when the plug 34 closes the powder outlet passage 33, each side of the plug partition portion 341 can be fitted into each sliding groove 331, ensuring that there is no gap between the plug partition portion 341 and the inner wall of the powder outlet passage 33, thereby preventing milk powder from seeping in from above or flowing out from below between the two plug partition portions 341 and ensuring the accuracy of metering.

[0042] In this embodiment, the plug operation portions 342 of the two plugs 34 are respectively located outside different sides of the quantitative powder outlet nozzle 3. This is for convenient operation and to avoid mutual interference.

[0043] At the same time, as Figures 4 to 6 , in order to facilitate the secondary use of the quantitative powder outlet nozzle 3, in this embodiment, the quantitative powder outlet nozzle 3 includes a powder outlet main body 36 and two converging portions 37 provided at both ends of the powder outlet main body 36.

[0044] The powder outlet main body 36 is in the shape of a rectangular hollow tube. The two converging portions 37 have converging grooves 371, and the converging outlets 372 at the outer ends of the converging grooves 371 away from the powder outlet main body 36 are of a tapered design. The converging outlets 372 of the two converging portions 37 are respectively communicated with the powder inlet 31 and the powder outlet 32.

[0045] Because there are converging grooves 371, and one end of the converging groove 371 is large and the other end is small. By connecting the large end of the converging groove 371 to the powder outlet main body 36, the perimeter of the powder outlet main body 36 can be increased to reduce the overall length of the powder outlet main body 36 (the length of the upper and lower ends of the powder outlet main body 36) and ensure that the quantitative area 35 has sufficient capacity, while the small end of the converging groove 371 can be aligned with the bottle mouth to ensure that the milk powder will not leak.

[0046] Moreover, the collecting trough 371 near the powder outlet 32 can ensure that the metered milk powder in the metering area 35 is completely discharged and flows into the feeding bottle, preventing milk powder from remaining in the metering area 35. When the user temporarily needs to disassemble the can body 1, the collecting funnel 2, and the metering powder outlet nozzle 3, the collecting trough 371 near the powder inlet 31 allows the milk powder remaining inside the metering powder outlet nozzle 3 to flow back to the collecting funnel 2 and then back to the can body 1 through the collecting trough 371 and the powder inlet 31, avoiding milk powder remaining inside the disassembled collecting funnel 2 and metering powder outlet nozzle 3.

[0047] In this embodiment, the powder outlet main body 36 is a hollow rectangular body. The collecting inlet 373 of the collecting trough 371 can be rectangular and communicate with the powder outlet main body 36, and the collecting outlet 372 can be circular. Thus, the cross-section of the collecting trough 371 is approximately funnel-shaped to facilitate the outflow of milk powder.

[0048] Furthermore, hollow-shaped powder inlet parts 38 and powder outlet parts 39 can be respectively connected to the outer ends of the two collecting parts 37. The powder inlet part 38 is used for threaded connection with the funnel outlet 22, and the outer end of the powder inlet part 38 is the powder inlet 31. In this embodiment, internal threads are provided inside the powder inlet part 38, and the funnel outlet 22 has a protruding threaded part 221 with external threads, but this is not limiting. The outer end of the powder outlet part 39 is the powder outlet 32, and a powder outlet cover 40 is threadedly connected to the outer end of the powder outlet part 39 for moisture-proof protection. In this embodiment, external threads are provided outside the powder outlet part 39, and internal threads are provided on the powder outlet cover 40, but this is not limiting.

[0049] In this embodiment, the opening 11 of the can body 1 is threadedly connected to either the funnel inlet 21 of the collecting funnel 2 or the can body cover 12. In this embodiment, external threads are provided on the opening 11 of the can body 1, and internal threads are provided inside the funnel inlet 21 and the can body cover 12, but this is not limiting.

[0050] For another example Figure 8 As shown, in this embodiment, multiple metering powder outlet nozzles 3 can be provided. Taking two pins 34 provided on each metering powder outlet nozzle 3 as an example, having only two pins 34 makes it more convenient to use, reduces the workload of preparation, and allows the user to prepare milk powder more easily.

[0051] The distances between the pins 34 on each metering powder outlet nozzle 3 are different, so that there are different preset capacities between the two pins 34 of each metering powder outlet nozzle 3. For example, among the three metering powder outlet nozzles 3 shown in the figure, from left to right, they can be set as a powder outlet nozzle with a capacity of six spoons of milk powder, a powder outlet nozzle with a capacity of three spoons of milk powder, and a powder outlet nozzle with a capacity of one spoon of milk powder. Of course, other capacity designs can also be made according to actual needs. For different models of metering powder outlet nozzles 3, their shapes and sizes are the same, and the positions where the closing pins 34a are located are also the same. By changing the positions of the metering pins 34b, the capacities of different metering areas 35 are obtained, so as to obtain metering powder outlet nozzles 3 with different metering amounts. For multiple different metering powder outlet nozzles 3, when there are only two pins 34, it is more convenient to use. Take the following operation as an example: Suppose the daily food intake of a certain infant at this stage is 180 ml of water with six spoons of milk powder per meal. The user can select a powder outlet nozzle with a capacity of six spoons. With the closing pin 34a in the closed state, pull the metering pin 34b to make the milk powder flow from the collecting funnel 2 into the metering powder outlet nozzle 3 and fill the metering area 35. Then close the metering pin 34b and open the closing pin 34a to let the milk powder in the metering area 35 flow out of the metering powder outlet nozzle 3 and into the feeding bottle. Thus, the preparation of milk powder can be completed in one operation, saving the workload of the preparer and making it easier for the user to prepare milk powder. The metering powder outlet nozzle is small in volume and low in cost. Consumers can purchase multiple metering powder outlet nozzles with different metering amounts at one time and replace them according to the changing food intake of the infant. Since the metering powder outlet nozzle 3 is used, the preparation of liquid milk will be more accurate, thus ensuring the digestion and absorption of the infant. Moreover, there is no need to hold a spoon and reach into the can body 1, which can avoid contamination. At the same time, through the setting of the metering powder outlet nozzle 3 and the cooperation of each pin 34, the large-area exposure of the milk powder in the can body 1 is avoided, making the milk powder not easy to get damp and caked, nor easy to be contaminated.

[0052] In this embodiment, the metering powder outlet nozzle 3 and the collecting funnel 2 are made of transparent materials to facilitate observing the remaining amount of milk powder in the powder outlet channel 33 and the collecting funnel 2, so as to judge the remaining amount of milk powder inside the can body 1.

[0053] Such as Figures 1 to 4 , the can body 1 structure of this embodiment further includes a bracket 4. The can body 1 is removably suspended on the bracket 4; the top of the can body 1 is the opening 11. By suspending the can body 1 upside down through the bracket 4, it can ensure that all the milk powder is taken out fully, avoiding waste and saving resources.

[0054] Of course, the can body 1 can also be suspended in other forms.
