Description

Technical Field

[0001] This invention relates to the field of daily-use environmentally friendly containers and beverage brewing technology, specifically a biodegradable and environmentally friendly mother-and-child portable cup. Background Technology

[0002] With increasing environmental awareness and the prevalence of fast-paced lifestyles, a significant contradiction has arisen between the pollution problem caused by disposable beverage cups and the demand for convenient portable beverage preparation. Traditional disposable beverage cups are mostly made of plastic or paper-plastic composite materials, which are difficult to degrade, placing enormous pressure on the environment. Meanwhile, existing portable beverage preparation products on the market, such as tea bags and espresso concentrates, while convenient to use, often suffer from the following drawbacks: 1. Traditional tea bags and similar products lose their tea concentration very quickly when brewed multiple times. The first brew is too strong and subsequent brews are too weak, which fails to achieve a balanced release of flavor compounds and affects the drinking experience.

[0003] 2. Most portable cups are only containers and do not have built-in, controllable release of beverage ingredients. Users need to carry and add them themselves, which is not convenient.

[0004] 3. Even if biodegradable materials are used, the overall structural design often does not fully consider the environmentally friendly treatment of all components after use, or the internal functional components are still made of non-biodegradable materials.

[0005] 4. A simple single-layer cup body cannot prevent scalding, while adding non-degradable plastic or foam material interlayers goes against the original intention of environmental protection; at the same time, the long-term preservation and sealing of pre-packaged food is also a major challenge. Summary of the Invention

[0006] The technical problem to be solved by this invention is to overcome the above-mentioned technical defects and provide a biodegradable and environmentally friendly mother-and-child portable cup.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A biodegradable and environmentally friendly mother-and-child portable cup, characterized in that it comprises: The cup body assembly has a double-layer structure and is designed to prevent burns. At least one built-in biodegradable cup is placed inside the cup body assembly, the built-in biodegradable cup being made of environmentally friendly biodegradable material; A sealing cap for removably sealing the opening of the cup assembly; A filter screen is disposed inside the cup body assembly; A tea cartridge is disposed at the bottom of the cup body assembly. The tea cartridge is a compressed tea with red dates as the base carrier and has at least one water injection slow release hole. The tea cartridge can release tea-effect substances in a timely, quantitative, and multiple manner according to the temperature changes of the injected water, and achieve balanced release during multiple water injections.

[0008] Specifically, the double-layer cup structure includes: Outer cup shell; The inner cup liner forms a heat-insulating cavity with the outer cup shell; A composite aluminum foil film layer is applied to the inner wall of the inner cup liner. The heat insulation cavity can be filled with air or evacuated to enhance the heat insulation effect, while the composite aluminum foil film layer is mainly used to improve the barrier properties and structural strength of the cup liner.

[0009] Specifically, the built-in biodegradable cups are two in number, allowing for use by two people, and are made of rice husk fiber. The rice husk fiber molded cups have good strength and heat resistance, and are completely biodegradable after disposal.

[0010] Specifically, the sealing cap is made of aluminum foil and is sealed to the opening edge of the cup assembly using a one-time hot-pressing process, forming a preservation seal that isolates the product from outside air. This seal is broken before first use, ensuring the hygiene of the product and the freshness of the beverage ingredients after it leaves the factory.

[0011] Specifically, the filter screen is positioned above the tea cartridge to isolate tea residue released from it. The filter screen itself is also made of biodegradable materials, such as PLA (polylactic acid).

[0012] Specifically, the tea pellet is a solid block made through a compression molding process. Its base carrier is dried and pulverized jujube pulp, which is compounded with tea extract or tea powder. The jujube pulp serves as both a flavoring agent and a binder and a slow-release matrix.

[0013] Specifically, the water-injection slow-release pores are one or more micropores penetrating the tea cartridge body. Their pore size, density, and three-dimensional distribution structure are configured to achieve a release kinetic curve of "initial rapid immersion - subsequent continuous slow release" at different water temperatures by controlling the water penetration rate and the dissolution and diffusion rate of tea active substances. This is the core of achieving balanced brewing.

[0014] Specifically, the release kinetics of the tea cartridge enable it to release a portion of the tea-effect substances when hot water is first poured in, and to continue to release the remaining tea-effect substances in proportion when hot water is poured in multiple times, thereby ensuring a relatively balanced tea concentration after multiple infusions.

[0015] Another aspect of the present invention provides a process for preparing the biodegradable and environmentally friendly mother-and-child portable cup as described above, characterized by comprising the following steps: S1: Prepare a double-layered cup body and laminate an aluminum foil film layer into the inner liner; S2: Made of rice husk fiber raw material, molded with an internal biodegradable cup; S3: Mix the jujube carrier with tea ingredients, compress and mold them to prepare jujube concentrated tea cartridges, and form water injection slow release holes in the tea cartridges; S4: Place a tea scoop at the bottom of the cup and install a filter screen above the tea scoop; S5: Place the built-in biodegradable cup into the cup body; S6: The sealing cap is made of aluminum foil material and sealed to the cup opening through a hot-pressing process; S7: Conduct overall inspection and packaging.

[0016] Specifically, the preparation process of the tea bullet includes washing, drying, and crushing red dates, uniformly mixing them with tea extract, pressing them into shape under specific temperature and humidity, and forming water injection slow-release holes with specific slow-release functions by laser or mechanical drilling; after the entire portable cup system is used, its main components can be naturally degraded or easily recycled, without causing pollution to the environment.

[0017] The advantages of this invention compared to existing technologies are: 1. This invention scientifically regulates the dissolution kinetics of tea active substances by designing tea cartridges with specific pore size, density, and three-dimensional structure for slow-release water infusion. Upon initial infusion, hot water rapidly wets the surface of the tea cartridge through the slow-release pores, releasing approximately 30%-40% of the flavor compounds, resulting in a palatable first brew. Subsequent infusions of hot water allow water to continue penetrating inwards through complex microporous channels, dissolving the inner layers and achieving a slow, continuous release of the remaining substances. This "rapid initial infusion followed by continuous slow release" model breaks the limitations of traditional tea bags, which tend to be "strong in the first brew and weak in subsequent brews," ensuring that the tea concentration remains relatively balanced after at least 2-3 infusions, significantly improving the drinking experience and cost-effectiveness.

[0018] 2. The main body of the cup is made of fully biodegradable materials such as rice husk fiber; the tea cartridge uses natural ingredients such as red dates as a carrier; the filter screen uses biodegradable materials such as PLA; and the sealing aluminum foil is easy to recycle. The entire product system, from raw materials to waste disposal, implements the concept of environmental protection throughout the entire chain, truly realizing "from nature, back to nature," effectively alleviating the white pollution problem caused by disposable products.

[0019] 3. Featuring a "mother-daughter cup" structure, the main cup contains two independent biodegradable drinking cups. Upon opening the packaging, the built-in cups can be directly removed and shared with others, eliminating the need to search for additional cups. This makes it ideal for sharing in outdoor, travel, and office settings, greatly enhancing convenience. Attached Figure Description

[0022] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0023] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0024] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figures 1 to 3 As shown, the technical solution of the present invention is as follows: a biodegradable and environmentally friendly portable cup, mainly comprising a double-layered cup body 2 as the main container, two independent built-in biodegradable cups 3 placed inside it, a sealing cap 1 for sealing the cup mouth, a filter screen 4 set in the lower middle part of the cup body, and a functional component at the bottom of the cup body as the core of the beverage—a red date concentrated tea cartridge 5. The tea cartridge 5 is processed with several water injection slow-release holes 6.

[0026] In one embodiment of the present invention, the double-layered cup body 2 constitutes the main outer shell and direct container of the portable cup. Its structure, from the outside to the inside, is as follows: The outer cup shell 201 is usually made of environmentally friendly and biodegradable materials such as rice husk fiber and bamboo fiber through a molding process. It has a certain mechanical strength and rough texture, making it easy to hold.

[0027] A narrow, sealed interlayer space exists between the outer cup shell 201 and the inner cup liner 202. This cavity can be filled with air, or in a more preferred embodiment, it can be evacuated to form a vacuum insulation layer, which can greatly slow down the outward conduction of heat from inside the cup, thereby achieving a good heat preservation effect and ensuring that the temperature of the outer wall of the cup does not become too high, thus achieving the function of preventing burns.

[0028] The inner cup liner 202 comes into direct contact with the beverage and is typically made of food-grade biodegradable polymer material. Its inner wall is laminated with a composite aluminum foil film layer 203. This film layer is usually composed of aluminum foil and a biodegradable plastic film, enhancing the barrier properties of the inner cup liner, preventing oxygen and moisture from permeating through the cup wall and affecting the contents, and increasing the structural strength and rigidity of the inner cup liner.

[0029] In one embodiment of the present invention, there are two built-in biodegradable cups 3, which are placed side by side or stacked inside the double-layered cup body 2. The built-in biodegradable cups 3 are also molded from rapidly biodegradable materials such as rice husk fiber, with moderate wall thickness and sufficient rigidity to hold hot water. When the user opens the sealed lid 1 of the portable cup, they can directly remove these two independent cups and share the brewed beverage with a companion, achieving a convenient sharing experience of "ready to use, no need for additional cups." After use, the built-in cups 3 can be discarded along with the main cup body into biodegradable waste or composting environments.

[0030] In one embodiment of the invention, the sealing cap 1 is a circular aluminum foil with a diameter slightly larger than the opening diameter at the top of the cup body assembly. During factory packaging, a hot-press sealing machine is used to fuse the periphery of the aluminum foil sealing cap 1 with the polymer material at the edge of the opening at the top of the double-layer cup body 2 under specific temperature and pressure, forming a continuous, strong, and highly airtight seal. This one-time sealing structure can completely isolate external air, moisture, and microorganisms, ensuring that the tea cartridge 5 and the cup body inside remain dry and hygienic during storage, transportation, and sales, without flavor deterioration or moisture absorption. Users need to tear or peel off this aluminum foil cap before use.

[0031] In one embodiment of the invention, the filter mesh 4 is a circular or polygonal mesh component, the edges of which are fixed to the inner wall of the double-walled cup body 2 by snaps, heat fusion, or biodegradable adhesive, and is located approximately in the lower middle part of the cup body. The mesh size of the filter mesh 4 is carefully designed to be large enough to allow water flow and dissolved tea components to pass freely, yet small enough to block tiny jujube pulp or tea dust that may be generated during the steeping process of the tea ball 5. The filter mesh 4 itself is also made of biodegradable materials, such as PLA woven mesh or cellulose-based materials.

[0032] In one embodiment of the present invention, the tea cartridge 5 is the core component for realizing the intelligent slow-release function of the present invention. It is a solid cylinder or flat sphere, formed by compressing processed jujube raw materials and tea components under high pressure.

[0033] In practical use, the user receives a perfectly sealed product. The cup body is made of double-layered biodegradable material, with two pre-installed rice husk fiber inner cups, a filter, and a concentrated red date tea cartridge. The cup opening is sealed with aluminum foil. After tearing off the aluminum foil seal 1, the user can directly pour hot water (85°C-100°C) into the double-layered cup body 2. The hot water passes through the filter 4 and reaches the tea cartridge 5 at the bottom. The hot water quickly soaks the tea cartridge through the slow-release holes 6, dissolving the flavor substances for the first infusion. After steeping for about 2-3 minutes, the first infusion is ready. The user can remove the two built-in biodegradable cups 3 and pour the tea from the main cup into these two smaller cups to share with a companion. The filter 4 effectively filters out tea residue. After drinking the first infusion, the user can pour hot water into the main cup again for a second infusion. This time, the hot water continues to penetrate deeper into the tea cartridge through the slow-release holes, dissolving more substances at a slower rate, resulting in a tea infusion with a concentration similar to the first infusion. This process can be repeated 2-3 times depending on the tea cartridge design. After consumption, all components—the double-walled cup body 2, the inner cup 3, the used filter 4, the remaining consumed tea cartridges 5, and the torn aluminum foil lid 1—can be disposed of as a whole in industrial composting or in the natural environment. The main materials, such as rice husk fiber and PLA, will be decomposed by microorganisms within a few months, and the aluminum foil can also enter the metal recycling process, achieving near-zero pollution and environmentally friendly treatment.

[0034] The specific preparation process includes the following steps: S1: Preparation of the double-layered cup body: The outer cup shell 201 and the inner cup liner 202 are molded separately. A pre-made aluminum foil composite film is laminated onto the outer surface of the inner cup liner 202 to form a composite aluminum foil film layer 203. Then, the inner cup liner 202 is placed inside the outer cup shell 201, and the two are sealed and connected at the cup mouth and bottom edge by means of heating and fusing or ultrasonic welding, forming a double-layered cup body 2 with a heat-insulating cavity in the middle.

[0035] S2: Preparation of built-in biodegradable cups: Mix rice husk fiber raw material with an appropriate amount of food-grade adhesive, and mold two independent built-in biodegradable cups 3 through hot pressing molding process.

[0036] S3: Preparation of concentrated jujube tea cartridges: Raw material processing: Red dates are washed, pitted, dried at low temperature, and then coarsely ground. Tea leaves are extracted to make concentrated powder, or directly ground into fine powder of a specific mesh size.

[0037] Mixing: Mix the jujube powder and tea ingredients thoroughly and evenly in a mixer according to a predetermined ratio.

[0038] Compression molding: The mixture is filled into a special mold, and under certain temperature and humidity conditions, high pressure is applied and the pressure is maintained for a certain time to form a dense solid tea cake blank.

[0039] Processing the slow-release holes: Using precision laser drilling equipment or a micro drill bit, a specific number and distribution of water injection slow-release holes 6 are machined on the tea cartridge blank according to a pre-programmed path to form the final tea cartridge 5. This step is crucial for controlling the release performance.

[0040] S4: Internal assembly of the main cup body: Place the pre-formed tea ball 5 at the bottom of the inner wall of the double-walled cup body 2. Install and fix the filter mesh 4 about 1-2 cm above the tea ball 5.

[0041] S5: Place the built-in cups: Place the two prepared built-in biodegradable cups 3 inside the double-layered cup body 2, above the filter isolation mesh 4.

[0042] S6: Sealed Packaging: Use aluminum foil as a sealing cap 1 to cover the cup mouth. Use a heat sealing machine to heat-press the periphery of the aluminum foil cap 1 to the composite material at the cup mouth of the double-layer cup body 2 under appropriate temperature and pressure to form an airtight seal.

[0043] S7: Inspection and Packaging: Leakage testing and visual inspection are performed on sealed finished products. Qualified products are placed in outer packaging boxes and put into storage.
