Description

Technical Field

[0001] This application relates to the field of teaching aids technology, and in particular to a modular two-color highlighter. Background Technology

[0002] In the current stationery market, highlighters are widely used as an important marking tool in learning, office work, and other settings. Traditional highlighters typically only offer a single color, making it difficult to meet users' needs for marking with multiple colors. To overcome this limitation, dual-color highlighters have gradually emerged on the market. By integrating two different colored refills, they allow users to make dual-color marks without changing the pen.

[0003] However, existing dual-color highlighters still have some obvious design flaws. First, the arrangement of the dual-color refills is often not reasonable. Some dual-color highlighters place the two refills side by side, resulting in an overly thick pen body that is inconvenient to carry and use; others place the two refills at the same end, requiring rotation or switching mechanisms to select the color, but this is complicated to operate and can easily cause color confusion during use.

[0004] Secondly, the existing dual-color highlighters also have shortcomings in the cap design. The connection between the cap and the pen body is not secure enough and is prone to falling off during use, resulting in damage to the pen tip or the ink drying out.

[0005] Furthermore, existing dual-color highlighters have shortcomings in their casing design. The lack of effective locking mechanisms at both ends of the casing prevents the cap from being securely attached, further exacerbating the problem of the cap falling off. Utility Model Content

[0006] The purpose of this application is to provide a modular dual-color highlighter to overcome or alleviate the aforementioned technical problems in the prior art.

[0007] In order to achieve the above objectives, this application provides the following technical solutions:

[0008] A modular dual-color highlighter includes: a dual-color refill assembly, a shell, and a cap assembly, wherein:

[0009] The two-color pen refill assembly has a first pen tip and a second pen tip, which are located at opposite ends of the two-color pen refill assembly.

[0010] The inner cavity of the housing houses the two-color pen refill assembly, such that the first pen tip and the pen tip are exposed at both ends of the housing;

[0011] Each of the two ends of the housing is provided with an engaging outer edge;

[0012] The pen cap assembly includes a first pen cap and a second pen cap. The first pen cap and the second pen cap have the same structure and each includes a top cap structure and a cap seat structure. The top cap structure and the cap seat structure are nested together. The cap seat structure is provided with an engaging inner edge, which engages with the engaging outer edge to fix the first pen cap and the second pen cap at both ends of the housing, respectively.

[0013] Optionally, the top cap structure is provided with a female buckle, and the top seat structure is provided with a male buckle. The male buckle engages with the female buckle so that the top cap structure and the top seat structure are nested and connected.

[0014] Optionally, the female buckle is disposed at the axis of the top cap structure, and the male buckle is disposed on the end face of the top seat structure facing the axis, so that the male buckle engages with the female buckle.

[0015] Optionally, the female snap fastener is a snap shaft, and the male snap fastener is an open claw formed on the end face of the cap structure facing the axis. The snap shaft is nested in the open claw so that the top cap structure and the cap structure are nested and connected.

[0016] Optionally, the outer surface of the housing comprises several rectangular planes joined together at a set angle to form a multifaceted gripping contact surface.

[0017] Optionally, the outer surfaces of the top cap structure and the top seat structure are formed by joining several triangular planes at a set angle to create a halo refraction surface.

[0018] Optionally, the top cap structure is a spherical structure, and the top seat structure is a columnar structure. The spherical structure has an inner recess for a female buckle to be provided in the inner recess, and the columnar structure has a flange for a male buckle to be provided on the flange. The male buckle engages with the female buckle so that the top cap structure and the top seat structure are nested together.

[0019] This invention provides a modular dual-color highlighter. By optimizing the arrangement of the dual-color refills, the first and second tips are positioned at opposite ends of the refill assembly, resulting in a slimmer and more portable pen. Simultaneously, the cap assembly employs the same structural design, allowing users to freely combine cap and refill colors as needed, enhancing flexibility and convenience. Furthermore, the inner cavity of the casing tightly accommodates the dual-color refills, and both ends have engaging outer edges that securely engage with the inner edges of the caps, effectively preventing cap detachment and refill movement.

[0029] See above Figures 1-6As shown in the embodiment of this application, a modular dual-color highlighter is provided. This modular dual-color highlighter includes: a dual-color refill assembly 1, a housing 2, and a cap assembly 3, wherein:

[0030] The two-color pen refill assembly 1 has a first pen tip 11 and a second pen tip 12, with the first pen tip 11 and the second pen tip 12 located at both ends of the two-color pen refill assembly 1;

[0031] The inner cavity of the housing 2 houses the two-color pen refill assembly 1, so that the first pen tip 11 and the pen tip are exposed at both ends of the housing 2;

[0032] Each of the two ends of the housing 2 is provided with a snap-fit ​​outer edge 21;

[0033] The pen cap assembly 3 includes a first pen cap 31 and a second pen cap 32. The first pen cap 31 and the second pen cap 32 have the same structure and each includes a top cap structure 301 and a cap seat structure 302. The top cap structure 301 and the cap seat structure 302 are nested together. The cap seat structure 302 is provided with an engaging inner edge 303, which engages with the engaging outer edge 21 to fix the first pen cap 31 and the second pen cap 32 at both ends of the housing 2, respectively.

[0034] Therefore, this utility model provides an innovatively designed modular dual-color highlighter, which has the following technical advantages:

[0035] Firstly, addressing the problem of traditional two-color highlighters being bulky and inconvenient to carry due to their illogical refill arrangement, this invention cleverly designs the two-color refill assembly 1 with a two-end layout, where the first pen tip 11 and the second pen tip 12 are located at opposite ends of the assembly. This design not only makes the pen body more slender and ergonomic, making it easier for users to hold and carry, but also allows users to quickly switch pen tip colors as needed without complex rotation or switching operations, thus improving marking efficiency.

[0036] Secondly, the design of the pen cap assembly 3 is also a major highlight of this utility model. The first pen cap 31 and the second pen cap 32 adopt the same structural design, including a top cap structure 301 and a cap base structure 302, which are nested together. This ensures the stability of the pen cap and allows users to freely match the colors of the pen cap and the refill according to their personal preferences or actual needs. This modular design not only reduces production costs but also greatly improves the flexibility and convenience of use, meeting the diverse needs of users.

[0037] Furthermore, the design of the casing 2 also fully considers the combination of practicality and aesthetics. The inner cavity of the casing 2 tightly accommodates the dual-color pen refill assembly 1, ensuring the stability of the pen refill within the casing and preventing shaking or displacement. Simultaneously, the engaging outer edges 21 at both ends of the casing tightly engage with the engaging inner edges 303 of the pen cap, forming a robust connection mechanism. This design not only effectively prevents the pen cap from falling off during use but also further enhances the overall stability of the pen body, extending the lifespan of the highlighter.

[0038] Optionally, the top cap structure 301 is provided with a female buckle 311, and the top seat structure 302 is provided with a male buckle 312. The male buckle 312 engages with the female buckle 311 so that the top cap structure 301 and the top seat structure 302 are nested and connected.

[0039] Optionally, the female buckle 311 is disposed at the axis of the top cap structure 301, and the male buckle 312 is disposed on the end face of the top cap structure 302 facing the axis, so that the male buckle 312 engages with the female buckle 311.

[0040] Therefore, in the design of the modular dual-color highlighter, the female buckle 311 is located at the axis of the top cap structure 301, while the male buckle 312 is located on the end face of the header structure 302 facing the axis. This design has the following technical advantages:

[0041] 1. Enhance structural stability

[0042] Axial symmetry design: The female and male latches are located at the axis of the top cap structure and the top seat structure, respectively. This symmetrical design ensures that the pen cap is subjected to uniform force when locked, reducing stress concentration caused by eccentric or asymmetrical locking, thereby enhancing the stability of the connection between the pen cap and the shell.

[0043] A robust locking mechanism: The interlocking male and female clips ensure a secure hold on the pen cap to the casing. This design not only effectively prevents the cap from falling off due to accidental impacts or bumps during use, but also improves the overall durability of the highlighter.

[0044] 2. Improve user experience

[0045] Easy and quick assembly / disassembly: The female and male clips engage in a simple and intuitive manner, allowing users to quickly assemble or disassemble the pen cap with just a gentle press or rotation. This design not only improves user efficiency but also enhances the user experience.

[0046] Reduce misoperation: The snap-fit ​​design at the axis provides clear guidance during the assembly and disassembly of the pen cap, reducing the risk of damage to the snap-fit ​​or incorrect installation of the pen cap due to misoperation.

[0047] 3. Improve production efficiency and reduce costs

[0048] Standardized production: Since the female and male buckles have the same design and fixed position, the pen cap assembly can be produced in a standardized manner, reducing production costs and manufacturing difficulty.

[0049] Easy to assemble: The standardized snap-fit ​​design makes the assembly process of the pen cap and the shell simpler and faster, improving production efficiency.

[0050] Optionally, the female buckle 311 is a snap pin, and the male buckle 312 is an open claw formed on the end face of the cap structure 302 facing the axis. The snap pin is nested in the open claw so that the top cap structure 301 and the cap structure 302 are nested and connected.

[0051] Therefore, in the design of the modular dual-color highlighter, the female buckle 311 is designed as a retaining shaft, while the male buckle 312 is designed as an open claw on the end face of the cap structure 302 facing the axis. The retaining shaft is nested in the open claw to achieve the nested connection between the top cap structure 301 and the cap structure 302. This design has the following technical advantages:

[0052] 1. Enhanced structural stability

[0053] Sturdy locking mechanism: The locking mechanism between the pin and the opening claw is similar to a pin connection in a mechanical joint, providing stable axial constraint and radial support. This design ensures the pen cap is firmly attached to the housing and is not easily dislodged even in the event of accidental impact or bumps.

[0054] Reduced wobbling: The tight fit between the locking pin and the opening claw reduces the gap between the pen cap and the housing, thus avoiding wobbling of the pen cap during use and improving writing stability and comfort.

[0055] 2. Improved ease of use

[0056] Quick assembly and disassembly: The engagement mechanism of the locking pin and the open claw is simple and intuitive, allowing users to easily assemble and disassemble the pen cap without the need for additional tools. This design improves user efficiency and makes pen cap replacement and cleaning more convenient.

[0057] Anti-misoperation design: The engagement of the locking pin and the opening claw has clear guidance, and users can feel obvious engagement feedback when removing or installing the pen cap, thus avoiding problems such as damage to the locking pin or incorrect installation of the pen cap due to misoperation.

[0058] 3. Improved durability

[0059] Reduced wear: The engagement mechanism of the clasp and the open claw reduces the frictional area and force between the pen cap and the housing, thereby lowering the wear rate. This design extends the lifespan of both the pen cap and the housing, reducing the frequency of replacements due to wear.

[0060] Highly adaptable: The design of the retaining pin and opening claws offers flexibility and adaptability, accommodating minor differences between pen caps and shells of varying sizes and shapes. This design enhances the compatibility and versatility of the highlighter.

[0061] Optionally, the outer surface of the housing 2 includes several rectangular planes joined together at a set angle to form a multifaceted gripping contact surface.

[0062] Therefore, in the design of the modular dual-color highlighter, the outer surface of the shell 2 is designed as several rectangular planes joined together at a set angle to form a multi-faceted grip contact surface, which has the following technical advantages:

[0063] 1. Improve grip comfort

[0064] Ergonomically designed: The multi-faceted grip surface is more ergonomic, providing a more comfortable and hand-fitting grip experience. This design helps distribute grip pressure and reduce hand fatigue during prolonged use of highlighters.

[0065] Increased friction: The angles between the rectangular planes and the edge design increase the roughness of the outer surface of the casing, thereby improving the friction when the user holds it. This helps prevent the highlighter from slipping during use, improving writing stability and safety.

[0066] 2. Improve durability

[0067] Stress Dispersion: The multi-faceted grip design helps disperse the stress experienced by the highlighter during use. When the highlighter is subjected to external impact or pressure, the stress is distributed across multiple rectangular planes, thereby reducing the risk of damage to any single plane.

[0068] Deformation resistance: This design also enhances the shell's resistance to deformation. The angles between the rectangular planes and the edges provide additional support, allowing the shell to better maintain its original shape when subjected to external forces.

[0069] 4. Easy to clean and maintain: The rectangular flat design makes the highlighter casing easier to clean and maintain. Users can easily wipe away stains and dust from the casing surface with a damp cloth or paper towel without worrying about damaging the casing during the cleaning process.

[0070] Optionally, the outer surfaces of the top cap structure 301 and the top seat structure 302 are formed by connecting several triangular planes at a set angle to create a halo refraction surface.

[0071] Therefore, in the design of the modular dual-color highlighter, the outer surfaces of the top cap structure 301 and the base structure 302 are designed as several triangular planes joined together at a set angle to form a halo refraction surface, which has the following technical advantages:

[0072] 1. Enhance visual appeal

[0073] Unique Appearance: The combination of triangular planes creates a unique halo-like refraction surface, making the highlighter more distinctive and eye-catching. This design not only enhances the product's aesthetics but also increases its appeal as a personalized stationery item.

[0074] Halo effect: When light shines on the halo's refracting surface, it refracts and reflects, creating a captivating halo effect. This visual effect not only enhances the user's aesthetic experience but also increases the attractiveness of the highlighter when writing or displaying.

[0075] 2. Increase the fun factor in using it.

[0076] Interactive Experience: The halo-reflective surface design allows the highlighter to produce dynamic visual effects when writing or displaying, increasing the interactive experience between the user and the product. This design not only enhances the user's enjoyment but also helps to stimulate their creativity and imagination.

[0077] 4. Improved durability and stain resistance

[0078] Structural stability: The triangular planes are joined together at a predetermined angle, forming a stable structural shape. This design not only enhances the stability of the top cap and the base structure, but also improves their resistance to deformation and impact.

[0079] Easy to clean: The halo-reflective surface design makes the highlighter's casing smoother and easier to clean. Users can easily wipe away stains and dust from the casing without worrying about damaging it during the cleaning process.

[0080] Optionally, the top cap structure 301 is a spherical structure, and the top seat structure 302 is a columnar structure. The spherical structure has an inner recess for a female buckle 311 to be provided in the inner recess, and the columnar structure has a flange for a male buckle 312 to be provided on the flange. The male buckle 312 engages with the female buckle 311 so that the top cap structure 301 and the top seat structure 302 are nested and connected.

[0081] Therefore, in the design of the modular dual-color highlighter, the top cap structure 301 is a spherical structure, and the header structure 302 is a columnar structure. An inner recess is provided within the spherical structure to accommodate the female snap-fit ​​311, and a male snap-fit ​​312 is provided on the flange of the columnar structure. The nested connection between the top cap structure and the header structure is achieved through the engagement of the male and female snap-fits. This design scheme has several technical advantages:

[0082] 1. Structural stability and robustness

[0083] The combination of spherical and columnar structures: The spherical cap and columnar base combine to form a stable support system. The spherical structure evenly distributes pressure from all directions, while the columnar structure provides a solid supporting foundation; the combination enhances the overall structural stability.

[0084] The snap-fit ​​mechanism features a tight fit: the female snap-fit ​​in the recessed area and the male snap-fit ​​on the flange engage securely, forming a robust connection. This design ensures that the cap and the seat will not easily separate due to external force, enhancing the stability of the device.

[0085] 2. Ease of operation

[0086] Easy to assemble and disassemble: The combination of spherical and columnar structures, along with the snap-fit ​​design, makes assembling and disassembling the cap and base simple and quick. Users can easily assemble and disassemble the cap without the need for additional tools, facilitating refill replacement or cleaning.

[0087] Clear guidance: The concave recess of the spherical structure and the protrusion of the columnar structure have clear guidance, allowing users to easily align the buckle position during disassembly and assembly, avoiding problems such as buckle damage or inability to install correctly due to misoperation.

[0088] 4. Durability and stain resistance

[0089] Reduced wear: The concave recess of the spherical structure and the protruding flange of the columnar structure reduce the direct contact area, thereby reducing the wear rate. This design extends the service life of the cap and the seat, reducing the frequency of replacement due to wear.

[0090] Easy to clean: The combination of spherical and columnar structures makes the highlighter's casing easier to clean. Users can easily wipe away stains and dust with a damp cloth or paper towel without worrying about damaging the casing during the cleaning process.

[0091] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
