Description

Technical Field

[0001] This utility model relates to the field of beverage container technology, specifically a cup with a double-layer filter structure for traditional Chinese medicine tea beverages. Background Technology

[0002] Herbal tea beverages (such as wolfberry and chrysanthemum tea, honeysuckle tea, and herbal decoction teas) have become an important choice for modern people's daily drinks due to their health benefits and convenience. However, traditional cups are difficult to use when brewing herbal tea beverages. For example, the filtration precision is insufficient, and the residue of herbs affects the drinking experience. Traditional cups mostly use single-layer filters (pore size ≥ 2mm), which can only filter large pieces of herbs (such as wolfberries and chrysanthemums with a diameter > 5mm), but cannot block fine herbs (such as herbal powder, petal fragments, and decoction pieces). This results in a large amount of residue mixed in with the tea soup, which can easily cause choking when drinking and affects the taste (the residue has a strong bitter taste). Especially for finely ground herbal powders, the filtration effect is almost ineffective, and the residue has a high pass-through rate.

[0003] Therefore, we need to propose a cup with a double-layer filtration structure for traditional Chinese medicine tea beverages. Utility Model Content

[0004] The purpose of this utility model is to provide a cup with a double-layer filtration structure for Chinese herbal tea beverages. By setting a first filtration structure and a second filtration structure, a double-layer filtration is formed, making the tea soup clearer and avoiding the problems of choking and coughing when drinking and the strong bitter taste of residue affecting the taste, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cup with a double-layer filter structure for a traditional Chinese medicine tea beverage includes: The main structure includes a cup body and a cup lid. The cup lid and the cup body are assembled by threaded connection at the top opening. A drinking spout is provided on one side of the top of the cup lid and communicates with the inner cavity of the cup body. A first filtration structure is provided at the bottom of the cup lid. The first filtration structure includes a protruding post and a filter cylinder. The protruding post is located at the center of the bottom of the cup lid. The filter cylinder is threadedly installed at the lower end of the protruding post. The filter cylinder is used to hold the herbal tea beverage, and the outer wall of the filter cylinder is distributed with filter holes for filtering the herbal tea beverage once. The second filtration structure is located at the bottom of the cup lid. The second filtration structure includes a lower plug and a filter screen. The lower plug is shaped like an opening, and the filter screen is located inside the opening of the lower plug. The lower plug is connected to the lower port of the drinking spout by plugging and unplugging, thereby performing secondary filtration before drinking.

[0006] Preferably, the upper end of the filter cartridge is integrally formed with a threaded connection port, and a sealing ring is provided at the lower part of the threaded connection port. The lower end of the protrusion is provided with a threaded connection groove. The threaded connection port and the threaded connection groove are adapted to each other, and when the filter cartridge is installed at the lower end of the protrusion, the sealing ring abuts against the opening of the threaded connection groove to form a seal.

[0007] Preferably, it also includes a pressing structure for preventing the herbal beverage from floating, which is disposed at the lower end of the protruding post. The pressing structure includes a pressing block and a connecting rod, with the connecting rod located at the top center of the pressing block. When the filter cartridge is installed at the lower end of the protruding post, the pressing block protrudes into the inner cavity of the filter cartridge and there is a gap between it and the inner wall of the filter cartridge.

[0008] Preferably, the protruding post has a built-in cavity, the connecting rod is slidably inserted into the top of the threaded connection groove, and the upper end of the connecting rod extends into the cavity and is connected to a slider. A compression spring is provided between the top of the cavity and the slider. The compression spring causes the pressure block to press down the Chinese herbal tea beverage to prevent the Chinese herbal medicine from floating and causing insufficient soaking.

[0009] Preferably, a silicone plug is inserted into the upper end of the drinking spout, and one side of the plug is connected to the outer wall of the drinking spout via a strap.

[0010] Preferably, a handle is provided on one side of the outer wall of the cup body, and a silicone sleeve is provided on the handle for heat prevention.

[0011] Preferably, a silicone coaster is adhered to the bottom of the cup body, and the bottom of the coaster has a diamond-shaped anti-slip pattern.

[0012] Preferably, the bottom ring of the lower plug is integrally formed with a rim. When the lower plug is inserted into the lower port of the drinking spout, the rim abuts against the bottom of the cup lid. A pry bar is provided at the bottom of the rim for pulling out the lower plug to facilitate cleaning of the lower plug and filter.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model forms a double-layer filtration system by setting up a first filtration structure and a second filtration structure. The filter cartridge of the first filtration structure can perform a primary filtration of the herbal tea beverage, initially intercepting larger particles of medicinal residue; the filter screen of the second filtration structure performs a secondary filtration before drinking, further blocking fine medicinal residue, such as herbal powder, petal fragments, and medicinal slices, greatly improving the filtration accuracy, making the tea soup clearer, avoiding the problems of choking and coughing when drinking and the strong bitter taste of residue affecting the taste. In particular, it can effectively filter finely ground herbal powder, significantly reducing the residue throughput.

[0014] 2. The pressure structure located at the lower end of the protruding column uses a compression spring to press the herbal tea beverage downwards, preventing the herbs from floating and causing insufficient steeping. During the brewing process, the herbs may float due to buoyancy, affecting the dissolution of their active ingredients. The pressure structure ensures that the herbs remain steeped, allowing the active ingredients to fully dissolve into the tea, thus improving the quality and health benefits of the herbal tea beverage.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides a technical solution: A cup with a double-layer filter structure for a traditional Chinese medicine tea beverage includes: The main structure includes a cup body 1 and a cup lid 3. The cup lid 3 and the cup body 1 are assembled by threaded connection at the top opening. A drinking spout 4 with a protrusion on one side of the top of the cup lid 3 is connected to the inner cavity of the cup body 1. The cup body 1 can be made of food-grade 304 stainless steel, and the cup lid 3 can be made of food-grade PP material.

[0019] The first filter structure is located at the bottom of the cup lid 3. The first filter structure includes a protruding post 6 and a filter cylinder 7. The protruding post 6 is located at the center of the bottom of the cup lid 3. The filter cylinder 7 is threadedly installed at the lower end of the protruding post 6. The filter cylinder 7 is used to hold the herbal tea beverage, and the outer wall of the filter cylinder 7 is distributed with filter holes for primary filtration of the herbal tea beverage. The upper end of the filter cylinder 7 is integrally formed with a threaded connection port 8. A sealing ring 9 is provided at the lower part of the threaded connection port 8. The lower end of the protruding post 6 is provided with a threaded connection groove 10. The threaded connection port 8 and the threaded connection groove 10 are compatible. When the filter cylinder 7 is installed at the lower end of the protruding post 6, the sealing ring 9 abuts against the opening of the threaded connection groove 10 to form a seal.

[0020] The filter cartridge 7 is fitted with the threaded groove 10 at the lower end of the protrusion 6 via the threaded connection port 8, and can be fixed to the bottom of the cup lid 3 by rotation. After the Chinese herbal raw materials (such as wolfberry, chrysanthemum, and fine Chinese herbal powder) are placed into the filter cartridge 7, the protrusion 6 is connected. After adding boiling water into the cup body 1, the cup lid 3 and the cup body 1 are combined (threaded connection). The added hot water permeates the filter holes on the outer wall of the filter cartridge 7, comes into contact with the raw materials, dissolves the effective components to form tea soup, and the filter holes intercept large pieces of raw materials with a diameter >1mm (such as whole wolfberries and medicinal slices), achieving "preliminary separation of raw materials and tea soup", completing one filtration. The sealing ring 9 at the lower part of the threaded connection port 8 of the filter cartridge 7 abuts against the ring opening of the threaded groove 10 when the filter cartridge 7 is installed, filling the gap between the two (sealing gap ≤0.1mm), preventing unfiltered tea soup or raw material debris from leaking out from the threaded connection, and ensuring that all tea soup is preliminarily filtered through the filter holes.

[0021] In summary, the filter holes prevent large pieces of raw material from entering the tea soup at the bottom of the cup body 1, avoiding the choking and coughing caused by the mixing of raw material and tea soup in traditional cups, and initially reducing the residue content in the tea soup. The filter cylinder 7 serves as an independent raw material holding space, and can be directly disassembled and poured out after brewing, preventing raw material residue from scattering on the inner wall of the cup body 1 and reducing subsequent cleaning workload. The sealing ring 9 ensures that there is no "bypass leakage" during the first filtration, and all tea soup is filtered through the filter holes, preventing unfiltered tea soup from mixing in and affecting the taste.

[0022] The filter cartridge 7 is made of 304 stainless steel (thickness 0.3-0.5mm). The filter pores on the outer wall of the filter cartridge 7 have a diameter of 1-2mm and are evenly distributed around the perimeter (pore spacing 2-5mm). It can filter Chinese herbal medicine slices with a diameter >1mm (such as wolfberry, chrysanthemum, hawthorn slices, etc.). Please see Figure 1-5 : The second filtration structure is located at the bottom of the cup lid 3. The second filtration structure includes a lower plug 16 and a filter screen 18. The lower plug 16 is shaped like an opening, and the filter screen 18 is located inside the opening of the lower plug 16. The lower plug 16 is connected to the lower port of the drinking spout 4 by plugging and unplugging, so as to perform secondary filtration before drinking.

[0023] The lower plug 16 is shaped like an opening, and the filter 18 is fixed inside its opening. It is connected to the lower port of the drinking spout 4 by plugging and unplugging. It is made of silicone material (hardness 30-40 Shore A) and is fitted with an interference fit (fitting amount 0.2-0.3mm). Before drinking, the tea soup at the bottom of the cup body 1 needs to flow through the drinking spout 4. At this time, the filter 18 in the lower plug 16 performs secondary filtration of the tea soup. The filter 18 has a pore size ≤0.1mm, which can block the fine medicinal residue (such as Chinese medicine powder, petal fragments, and medicinal slice fragments) remaining after the first filtration, allowing only clear tea soup to flow out through the drinking spout 4.

[0024] In summary, the secondary fine filtration effectively intercepts the fine medicinal residue remaining after the first filtration, ensuring a clearer tea soup, improving the drinking experience, and completely resolving the issues of cloudy tea soup and bitter taste. It is especially suitable for brewing Chinese herbal powder. The plug-in connection allows the lower plug 16 to be quickly removed, facilitating the cleaning of fine residue in the pores of the filter screen 18 (e.g., rinsing with water for 30 seconds is sufficient), preventing residue from clogging the filter screen 18 and affecting the next filtration, while also preventing the accumulation of residue and the growth of bacteria.

[0025] The filter screen 18 is made of food-grade nylon (temperature resistance ≥120℃, acid and alkali corrosion resistance), and is made into a high-precision filter screen 18 (pore size 0.1-0.2mm) through a weaving process. It can block fine medicinal residues with a diameter >0.1mm (such as Chinese medicine powder, medicinal slices, and flower petal fragments). The non-porous edge of the filter screen 18 is reserved for fixing with the lower plug 16 ring. When the filter screen 18 is combined with the lower plug 16: the lower plug 16 is "mouth-shaped" (ring-shaped), and a stepped groove is processed on the inner side of its ring. 3-4 small protrusions (0.1mm high, 0.5mm in diameter) are evenly arranged on the inner side of the groove to lock the edge of the filter screen 18 and prevent the filter screen 18 from rotating or shifting in the groove; or the filter screen 18 and the lower plug 16 are directly ultrasonically welded to achieve a permanent combination of the nylon filter screen 18 and the lower plug 16 ring.

[0026] For a preferred embodiment, please refer to Figure 4-5 : The bottom ring of the lower plug 16 is integrally formed with a rim 17. When the lower plug 16 is inserted into the lower port of the drinking spout 4, the rim 17 abuts against the bottom of the cup lid 3. A pry bar 19 is provided at the bottom of the rim 17 for pulling out the lower plug 16 to facilitate cleaning of the lower plug 16 and the filter screen 18.

[0027] The rim 17 at the bottom of the lower plug 16 abuts against the bottom of the cup lid 3 when it is inserted into the lower port of the drinking spout 4, forming a "limiting structure" to prevent the lower plug 16 from being over-inserted, causing the filter 18 to stick to the inner wall of the drinking spout 4 and affecting the flow of tea soup. The lever 19 (10-15mm in length and 1mm in thickness) at the bottom of the rim 17 provides a point of force for the operator. The lower plug 16 can be easily removed by pinching the lever 19 with your fingers and pulling it down, without the need for tools.

[0028] The paddle 19 reduces the difficulty of removing the lower plug 16. Especially when the filter screen 18 adsorbs small residues, causing the lower plug 16 to fit tightly with the drinking spout 4, the paddle 19 can provide enough space to apply force, improving disassembly and cleaning efficiency.

[0029] For a preferred embodiment, please refer to Figure 3-5 : It also includes a pressing structure to prevent the herbal beverage from floating, located at the lower end of the protruding post 6. The pressing structure includes a pressing block 11 and a connecting rod 12. The connecting rod 12 is located at the top center of the pressing block 11. When the filter cylinder 7 is installed at the lower end of the protruding post 6, the pressing block 11 extends into the inner cavity of the filter cylinder 7 and there is a gap between it and the inner wall of the filter cylinder 7. The protruding post 6 has a cavity 14 inside. The connecting rod 12 is slidably inserted into the top of the threaded connection groove 10, and the upper end of the connecting rod 12 extends into the cavity 14 and is connected to a slider 13. A compression spring 15 is provided between the top of the cavity 14 and the slider 13. The compression spring 15 causes the pressing block 11 to press down the herbal tea beverage to prevent the herbal medicine from floating and causing insufficient soaking.

[0030] The protruding post 6 has a built-in cavity 14. The slider 13 at the upper end of the connecting rod 12 is slidably disposed in the cavity 14. The compression spring 15 connects the top of the cavity 14 and the slider 13. After the filter cartridge 7 is installed, the pressure block 11 is inserted into the inner cavity of the filter cartridge 7 (with a gap of 2-3mm between it and the inner wall of the filter cartridge 7). The compression spring 15 is in a slightly compressed state. The spring force pushes the slider 13 and the connecting rod 12 downward, so that the pressure block 11 applies continuous downward pressure (pressure 0.5-1N) to the Chinese herbal raw materials in the filter cartridge 7. For light Chinese herbal tea raw materials (such as chrysanthemum and honeysuckle petals), the pressure block 11 can press them down into hot water to prevent them from floating to the surface.

[0031] In summary, this design prevents the problem of "partially unsoaked" ingredients from floating to the surface, ensuring full contact between the ingredients and hot water, increasing the dissolution rate of active ingredients, ensuring uniform tea concentration, and reducing ingredient waste. The gap between the pressing block 11 and the inner wall of the filter cylinder 7 ensures smooth circulation and penetration of hot water into the ingredients, preventing "blockage of the filter holes by the pressing block 11" that could hinder tea flow, thus balancing the pressing effect with filtration efficiency.

[0032] For a preferred embodiment, please refer to Figure 1-5 : A silicone plug 5 is inserted into the upper end of the drinking spout 4, and one side of the plug 5 is connected to the outer wall of the drinking spout 4 by a strap.

[0033] The upper plug 5 is made of silicone (hardness 30-40 Shore A) and is inserted into the upper port of the drinking spout 4 through an interference fit (fitting amount 0.2-0.3mm) to form a seal; one end of the strap is connected to the upper plug 5, and the other end is fixed to the outer wall of the drinking spout 4 so that the upper plug 5 will not be lost after disassembly; when brewing, the upper plug 5 seals the drinking spout 4 to prevent hot air from escaping or dust from entering; when drinking, simply remove the upper plug 5, which is easy to operate.

[0034] In summary, the top stopper 5 seals the drinking spout 4, preventing hot steam from escaping during brewing and avoiding scalding when the lid is opened. It also prevents dust from entering the drinking spout 4, ensuring the hygiene of the tea. The strap connects the top stopper 5 to the drinking spout 4, avoiding the problem of traditional independent lids 3 being easily lost. This makes it especially suitable for outdoor and commuting use, enhancing the device's practicality.

[0035] For a preferred implementation, please refer to Figure 1-2 : A handle 2 is also provided on one side of the outer wall of the cup body 1, and a silicone sleeve is provided on the handle 2 to prevent scalding.

[0036] The handle 2 is fixed to the outer wall of one side of the cup body 1 to provide support for gripping; a silicone sleeve covers the handle 2 (thickness 2-3mm). The silicone material has a low thermal conductivity (≤0.2W / (m·K)) and can isolate the heat transferred from the cup body 1. Even if the cup is filled with 95℃ hot water, the surface temperature of the silicone sleeve is ≤50℃. At the same time, the surface of the silicone sleeve is provided with anti-slip texture (friction coefficient ≥0.8) to enhance the friction when gripping.

[0037] Overall, it can prevent burns caused by direct hand contact with the hot cup body, and is especially suitable for the scenario of "warm drinking" of Chinese herbal tea beverages, thus improving the safety of use.

[0038] For a preferred implementation, please refer to Figure 1-2 : A silicone coaster 21 is attached to the bottom of the cup body 1, and the bottom of the coaster 21 has a diamond-shaped anti-slip texture.

[0039] The silicone coaster 21 is adhered to the bottom of the cup body 1. The diamond-shaped anti-slip texture on the bottom (texture depth 0.5mm, spacing 2mm) increases the contact area and friction with the table. Even on smooth tabletops (such as glass or marble tabletops), the coaster 21 can form an "interlock" through the anti-slip texture to limit the cup from sliding.

[0040] It can prevent tea from spilling due to table vibration or accidental bumps, making it especially suitable for families with children or pets or outdoor bumpy scenarios (such as camping), improving stability and safety. The soft silicone material prevents the bottom of the cup 1 (such as glass or ceramic) from directly rubbing against the table and causing scratches, while also isolating the heat of the cup 1 from being transferred to the table, protecting the table material (such as wooden tabletops from being scalded).

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
