This not only improves ease of use but also avoids powder waste.

Description

Technical Field

[0001] This application relates to the field of food packaging, and more particularly to a combination can. Background Technology

[0002] Most cold-brew tea and other powdered beverages currently on the market use containers where the powder is stored in the cap and released via a puncture-film release mechanism. This method works by placing a membrane structure in the cap; when the user opens the cap, the membrane is punctured, releasing the powder into the main liquid compartment. However, this puncture-film release method has several drawbacks: a significant disadvantage is that moisture in the main compartment can easily permeate through the membrane into the powder storage area. This means that when external air humidity is high, moisture can easily penetrate, causing the powder to become damp and clump. This dampness and clumping severely affect the powder's solubility and shorten its shelf life, thus impacting the taste and user experience of the beverage.

[0003] In traditional designs, powder release is achieved through membrane rupture. However, this method does not provide sufficient control to precisely regulate the amount of powder released. Users cannot ensure that the required amount of powder is released each time, easily leading to powder waste or inaccurate dispensing. Because powder has frequent contact with water or air, it is susceptible to moisture or contamination, resulting in a decline in powder quality. Furthermore, existing containers often lack effective moisture-proof designs, allowing the powder to absorb moisture during storage, thus affecting its quality. Current powder storage containers have relatively simple operating mechanisms. Users need to operate the cap to release the powder, but this method often fails to meet the requirements for precise control, causing inconvenience during powder release. Utility Model Content

[0004] The purpose of this application is to overcome the problems mentioned above, such as the powder being easily exposed to moisture, poor powder storage safety, inaccurate powder release, and insufficient operational flexibility.

[0005] According to one aspect of this application, a combination tank is provided, comprising:

[0006] The tank body has a main receiving chamber inside, and the main receiving chamber has an openable injection port;

[0007] A bottom cover is attached to the end of the tank body opposite to the injection port;

[0008] The tank body is provided with a secondary receiving chamber at the end opposite to the injection port, which is sealed with the bottom cover to form a receiving cavity;

[0009] The receiving cavity is provided with a movable receiving unit, which is housed in the secondary receiving chamber and is adapted to the shape of the secondary receiving chamber for receiving powder.

[0010] Preferably, the movable receiving unit includes a body and an opening part, wherein the opening part is a sealing film, a screw-on cap, or a tear-off film structure, which can be actively opened by the user to release the powder therein during use.

[0011] Preferably, a limiting structure is provided between the outer wall of the receiving unit and the inner wall of the secondary receiving compartment to limit the shaking or rotation of the receiving unit after it is inserted.

[0012] Preferably, the limiting structure includes: a circumferential flange and a corresponding groove, or several vertical guide ribs and corresponding limiting grooves.

[0013] Preferably, the bottom of the housing unit is provided with a vent or pressure balance hole, and is equipped with a moisture-proof layer or filter membrane to prevent external moisture from entering the housing cavity.

[0014] Preferably, the bottom cover is provided with a locking mechanism for automatically limiting and fixing the receiving unit after it is inserted, including an elastic buckle, a rotating limiting ring, or a protruding locking device.

[0015] Preferably, an anti-opening identification structure is provided between the bottom cover and the tank body, including: a fracture ring disposed on the outer edge of the bottom cover, the fracture ring breaking during the initial opening process and being irreparable, serving as an opening warning indicator; or,

[0016] A color-changing recognition layer, which undergoes an irreversible color change upon exposure to air or after being torn, is used to indicate the open state; or...

[0017] Microporous sealing tape leaves a visible marking layer after removal.

[0018] Preferably, the can body is provided with a detachable portable hanging ring or buckle structure.

[0019] Preferably, the injection port is provided with a sealing cap, which is connected to the tank body by a threaded connection, a snap-fit ​​connection, or a flip-top structure.

[0020] Preferably, the tank body has a columnar, elliptical columnar, or polygonal columnar structure.

[0021] This application offers the following advantages: Physical isolation is achieved between the secondary and primary storage compartments, ensuring that moisture in the primary compartment does not penetrate into the powder storage area. Unless the user actively releases the powder, moisture and air cannot affect the powder storage environment. This significantly reduces the impact of moisture and contamination on powder quality, solves the problem of powder clumping due to moisture in existing technologies, and ensures the powder's shelf life. The movable storage unit of this invention is designed with a flexible release mechanism, allowing users to precisely control the amount of powder released by manually opening the seal, rotating the cap, or tearing the film. This not only improves ease of use but also avoids powder waste. Users can release the appropriate amount of powder according to different needs, thus avoiding the problem of inaccurate powder release in traditional technologies. Attached Figure Description

[0029] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0031] Please refer to Figure 1 - Figure 5 One embodiment of this application provides a combined can 100, including: a can body 20, a main receiving chamber 23 inside the can body 20, the main receiving chamber 23 having an openable injection port 22; a bottom cover 30 connected to one end of the can body 20 away from the injection port 22; a secondary receiving chamber 21 provided at one end of the can body 20 away from the injection port 22, which, together with the bottom cover 30, forms a receiving cavity; a movable receiving unit 40 is provided inside the receiving cavity, which is housed within the secondary receiving chamber 21 and is adapted to the shape of the secondary receiving chamber 21 for containing powder.

[0032] In this embodiment, the receiving unit is located within the secondary receiving compartment 21 and is adapted to the shape of the secondary receiving compartment 21 to ensure its stable placement and prevent shaking or displacement. The receiving unit can release the powder through user operation (such as unscrewing or tearing the film), ensuring precise release of the powder into the main receiving compartment 23. The secondary receiving compartment 21 and the main receiving compartment 23 are completely isolated; moisture in the main receiving compartment 23 cannot enter the secondary receiving compartment 21 before the bottom cover 30 is opened or the receiving unit is removed, preventing the powder from becoming damp and clumping, effectively extending the shelf life. The receiving unit design offers good mobility; users can adjust or remove the receiving unit as needed, precisely control the amount of powder released, avoid waste, and provide greater flexibility and convenience.

[0033] The beneficial effects of this application are that, through physical isolation design, it ensures that moisture from the main compartment will not penetrate into the powder storage area, greatly reducing the impact of moisture on powder quality and solving the problem of powder clumping due to moisture. Furthermore, the movable housing unit provides a flexible release mechanism, allowing users to precisely control the amount of powder released, thereby improving ease of use and avoiding powder waste.

[0034] In one specific embodiment, the movable containing unit 40 includes a body 41 and an opening portion. The opening portion is a sealing film, a screw-on cap, or a tear-off film structure, which can be actively opened by the user to release the powder. The containing unit includes a body 41 and an opening portion, which can be a sealing film, a screw-on cap, or a tear-off film structure. The user can choose the appropriate method to actively open it to release the powder. The sealing film design ensures that the powder is completely sealed during storage, preventing the entry of outside air or moisture. The screw-on cap structure provides a more convenient opening method, while the tear-off film structure is suitable for one-time opening, adapting to different users' usage habits and needs. This design allows the containing unit to have both good sealing performance and convenient user control over the release of powder when needed.

[0035] Optionally, a limiting structure is provided between the outer wall of the receiving unit and the inner wall of the secondary receiving chamber 21 to restrict the shaking or rotation of the receiving unit after insertion. The limiting structure includes: a circumferential flange and a corresponding groove, or several vertical guide ribs and corresponding limiting grooves. By implementing this technical solution, the limiting structure between the outer wall of the receiving unit and the inner wall of the secondary receiving chamber 21 effectively prevents the receiving unit from shaking or rotating after insertion. This limiting structure, including a circumferential flange and a corresponding groove, or several vertical guide ribs and corresponding limiting grooves, ensures the receiving unit is stably placed in the secondary receiving chamber 21, avoiding uneven powder release or inaccurate control due to shaking or rotation. This limiting structure further improves the stability of the receiving unit, ensures the airtightness of the powder storage environment, avoids the influence of external factors on powder quality, and improves the convenience and accuracy of use.

[0036] Optionally, the bottom of the receiving unit is equipped with vents or pressure equalization holes, along with a moisture-proof layer or filter membrane, to prevent external moisture from entering the receiving cavity. The vents or pressure equalization holes help balance the pressure difference inside and outside the receiving cavity, preventing deformation of the receiving unit or moisture absorption of the powder due to pressure differences. The moisture-proof layer or filter membrane isolates moisture, ensuring the powder remains dry during storage and preventing the humid environment from affecting its quality. This design further enhances the storage safety and shelf life of the powder, ensuring its quality stability during use.

[0037] The movable containing unit of this embodiment consists of a main body 41 and an opening part. The opening part can be a sealing film, a screw-on cap, or a tear-off film structure, which ensures the airtightness of the powder during storage and allows for precise release of the required amount by screwing or tearing. A limiting structure (such as a circumferential flange and groove locking or a guide rib and limiting groove) is provided between its outer wall and the inner wall of the secondary containing chamber 21 to prevent shaking or rotation and ensure uniform release. A vent hole or pressure balance hole is provided at the bottom and is used in conjunction with a moisture-proof layer / filter membrane to balance the pressure inside and outside the chamber while preventing moisture from entering, which significantly improves the stability and shelf life of the powder during dry storage. The user operation is simple and the release is flexible and controllable.

[0038] In one specific embodiment, the bottom cover 30 is equipped with a locking mechanism for automatically limiting and fixing the receiving unit after it is inserted. This mechanism includes an elastic buckle, a rotating limiting ring, or a protruding engagement device. In this embodiment, the bottom cover 30 integrates a locking mechanism that automatically engages with and limits the receiving unit after it is in place. The locking mechanism can be an elastic buckle, which elastically deforms and engages with the flange of the receiving unit when it is inserted; or a rotating limiting ring, which the user can easily flip by turning the bottom cover 30 to press against the side wall of the receiving unit, achieving mechanical locking; or a protruding engagement device, where the protrusion engages with a pre-set recess in the receiving unit to form a point-lock. This structure ensures that the receiving unit remains stable during transportation and use, preventing uncontrolled powder release due to vibration or tipping. Furthermore, when it needs to be removed, it can be easily disassembled with a simple unlocking action.

[0039] In one optional embodiment, an anti-opening identification structure is provided between the bottom cover 30 and the tank body 20, including: a fragile ring disposed on the outer edge of the bottom cover 30, which breaks during the initial opening process and cannot be restored, serving as an opening indication mark; or, a color-changing identification layer, which undergoes an irreversible color change after being exposed to air or torn by force, used to indicate the opening status; or, a microporous sealing sticker, which leaves a visible identification layer after being removed.

[0040] In this embodiment, it should be noted that the anti-opening identification structure is designed to provide an intuitive and irreversible means of indicating the opening status, effectively improving the product's anti-counterfeiting performance and the user's sense of security. The fragile breakage ring, through its structural design, physically breaks when the user first rotates or pulls open the bottom cover by 30 degrees, creating a permanent and irreversible mark that clearly indicates the packaging has been opened.

[0041] The color-changing recognition layer is based on a response mechanism to air, humidity, or mechanical tearing. It can change color after being opened, and this change is irreversible. It can serve as a long-term visual identifier of the open state, making it easy to identify whether the product is intact in the retail or transportation process.

[0042] The microporous sealing sticker design is more suitable for occasions that require partial sealing. After being removed, it leaves a prominent marking layer on the surface of the bottom cover 30 or the can body 20. It can also be combined with QR codes, brand logos, etc. to further enhance traceability and anti-counterfeiting capabilities.

[0043] The above structure can effectively record the user's initial opening operation, preventing the contents from being opened or replaced in advance. It is widely applicable to scenarios with high requirements for the safety of contents, such as cold brew tea, medicine, and functional beverages.

[0044] In one optional embodiment, the can body 20 is a cylindrical, elliptical cylindrical, or polygonal prism structure. It should be noted that the cylindrical, elliptical cylindrical, or polygonal prism structure design can be flexibly adjusted according to actual usage needs and aesthetics, meeting various requirements such as product display, hand grip, and packaging stacking in different scenarios.

[0045] Among them, the columnar structure is easy to mold and automatically fill, with lower manufacturing costs, and is suitable for standardized production; the elliptical columnar structure has better grip and fit, and is suitable for portable beverages or sports scenarios; the polygonal columnar structure is more visually distinctive and personalized, while also providing a certain degree of anti-rolling capability, making it more stable when placed on desktops or shelves.

[0046] This flexibility in form further expands the applicability of the Combination Can 100 in the food, beverage, and pharmaceutical industries, while also providing a wider range of appearance options for brand packaging design.

[0047] In one specific embodiment, the injection port 22 is provided with a sealing cap 10, which is connected to the can body 20 via a threaded connection, a snap-fit ​​connection, or a flip-top structure. In this embodiment, it should be noted that the diverse material choices for the can body 20 allow the combined can 100 to be suitable for different usage scenarios and packaging needs. Plastic materials are convenient for single use and have lower costs, while metal materials offer higher strength and barrier properties, and composite materials combine lightweight and structural strength, making them suitable for food or health product packaging with high requirements for shelf life and strength. The various connection methods between the sealing cap 10 and the can body 20 (such as threads, snaps, and flip-tops) provide greater adaptability to the product, facilitating filling or reuse, effectively preventing leakage of contents, and meeting the opening habits and sealing needs of different users.

[0048] In one specific implementation, the canister 20 is equipped with a detachable portable hanging loop or buckle structure on its exterior. In this embodiment, it should be noted that the detachable portable hanging loop or buckle structure on the exterior of the canister 20 is designed to provide a convenient way to carry and hang the canister, meeting the user's needs in outdoor, travel, or sports scenarios. This design allows users to easily hang the combination canister 100 on backpacks, in vehicles, or other easily accessible locations, improving the product's portability and practicality.

[0049] The detachable hanging ring or snap-on structure features an easy-to-operate design, allowing users to quickly disassemble or install it as needed, providing flexibility for different usage scenarios. Furthermore, the material of the hanging ring or snap-on structure can be selected from plastic, metal, or other suitable materials based on the overall design of the tank 20 to ensure sufficient strength and durability while ensuring no additional weight is added.

[0050] This design not only enhances the product's functionality, but also increases its recognizability and market appeal by combining the shape of the hanging ring or buckle with the brand logo and other identifiers.

[0051] In an optional embodiment, the movable containing unit of the combined can 100 adopts a multi-layer stacked structure. Specifically, the containing unit is designed as multiple independent layers, each layer being fixed together by snaps or magnetic adsorption. Users can choose to use one or more layers as needed, thereby flexibly adjusting the amount of powder stored. This design not only increases the powder storage capacity but also maintains the compactness of the can 20. Each containing unit has vents and a moisture-proof layer at the bottom to ensure the powder remains dry during storage and effectively prevents moisture absorption and clumping.

[0052] In one alternative embodiment, the movable containing unit of the combination tank 100 adopts a modular design. The containing unit is designed as multiple independent small modules, each of which can be used individually or in combination. The modules are connected by standardized connectors (such as threads and slots), allowing users to easily adjust the powder storage volume according to their needs. This modular design not only improves the product's flexibility but also facilitates personalized configuration by users for different usage scenarios.

[0053] In an optional embodiment, the movable receiving unit of the combined container 100 is installed using a slide rail system. A slide rail is provided within the secondary receiving compartment 21, allowing the movable receiving unit to be inserted and removed. The slide rail design ensures smooth and stable insertion and removal of the receiving unit, preventing shaking or jamming. Furthermore, the bottom of the receiving unit is equipped with vent holes and pressure equalization holes, along with a moisture-proof layer, to prevent external moisture from entering, further enhancing the storage safety of the powder.

[0054] In an optional embodiment, the movable housing unit of the combined tank 100 employs a magnetic fixing structure. Magnetic material is applied to the contact surface between the housing unit and the secondary housing compartment 21, allowing the housing unit to be magnetically attracted and fixed, ensuring its stability during transportation and use. This design not only improves the stability of the housing unit but also facilitates quick installation and disassembly by the user.

[0055] In an alternative embodiment, the tank 20 may be provided with compartments for storing additional accessories. For example:

[0056] Straws: Features a dedicated slot or folding design, allowing straws to be rolled up and stored outside the container 20 or inside the bottom lid 30. Straws can be designed with adjustable length or built-in filtering to suit different user needs.

[0057] Spoon: A detachable small spoon is provided. The length of the spoon matches the 20mm depth of the can. The spoon head is designed with non-stick material for easy and accurate dispensing of powder or liquid.

[0058] Filter screen: A removable microporous filter screen is designed and located at the bottom of the can 20 or near the inlet 22 to prevent the formation of particles or impurities after the powder or liquid dissolves. It can be cleaned and replaced during use.

[0059] The canister 20 features multiple independent compartments for storing accessories (such as straws, spoons, and filters). These compartments can be divided using dividers, inner wall grooves, or removable partitions to ensure that accessories do not interfere with each other and are easily accessible. The compartment design can be adjusted according to the size of the accessories to ensure that each accessory has a suitable storage space. These accessories can be secured within the compartments using slots, grooves, hooks, or zippered pouches to prevent them from loosening or being lost during transportation or storage. Accessories are typically stored on the sides, bottom, or top of the canister 20 for easy access by the user.

[0060] The inner walls of the compartments can be made of soft materials, such as silicone, plastic, or fabric, to prevent damage to the accessories during storage. To ensure that the accessories are not contaminated by moisture or dust, sealing strips or lids can be designed at the openings of the compartments to provide good sealing and protection.

[0061] The compartment design must not only ensure the safe storage of accessories but also consider user convenience. Users can easily retrieve stored accessories by pulling open the sliding cover, opening the rotating cover, or removing the bottom cover 30. The accessory retrieval method can be designed for easy one-handed operation, avoiding inconvenience during use.

[0062] The embodiments described above are merely examples of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application.
