Description

Technical Field

[0001] This application relates to the field of container opening and closing structures, and in particular to a portable box with a one-hand push-pull opening and closing mechanism. Background Technology

[0002] In the portable case industry, with the accelerating pace of life and the ever-increasing demand for convenience, portable packaging for various products is receiving increasing attention. Especially for portable cases with special purposes, such as boxes for storing specific items, in addition to fulfilling basic storage functions, factors such as ease of use, environmental friendliness, lightweight design, visibility, and compatibility with the items being stored must be considered. A well-designed portable case not only improves user experience but also promotes the adoption and use of related products. For example, in scenarios where portability is paramount, an easy-to-use portable case allows users to access items more easily, thereby enhancing the product's practicality and market competitiveness. Furthermore, the use of environmentally friendly materials aligns with current societal pursuit of sustainable development, helping to reduce environmental impact.

[0003] Traditionally, packaging for items like nicotine pouches typically uses round boxes. These round boxes are designed with capacity in mind, holding a relatively large number of items to meet the user's needs for a certain period. They work by opening and closing the box through rotation, using threads or snap-fit ​​mechanisms to achieve a seal. In practice, round boxes are quite common and widely used for packaging various similar items. For example, some chewing gum and candy products also use similar round packaging boxes. The manufacturing process is relatively mature, with low production costs, allowing for mass production. Moreover, the round design is aesthetically pleasing and conforms to popular tastes. Additionally, the good sealing of round boxes can protect the contents from external environmental influences to a certain extent.

[0004] However, existing round box packaging has significant drawbacks. Its opening mechanism requires two hands; the user must first hold the box with one hand and then use the other to rotate and open the lid. In situations where using both hands is inconvenient, such as when the user is holding other items or in motion, this method is extremely cumbersome and fails to meet the user's need for quick and convenient access to items. Utility Model Content

[0005] The purpose of this application is to provide a portable case that can be opened and closed with one hand by pushing and pulling.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a portable case with a single-hand push-pull opening and closing mechanism, comprising a case body and a lid, wherein a sliding guide structure is provided between the case body and the lid to realize single-hand push-pull opening and closing; both the case body and the lid are made of polypropylene material.

[0007] By adopting the above technical solution, users can quickly and conveniently open and close the portable case without using both hands, greatly improving the convenience and efficiency of use, especially suitable for scenarios where users are busy with one hand. Both the case body and the lid are made of food-grade polypropylene (PP) material. This material not only has good chemical stability, impact resistance, and wear resistance, effectively protecting the items inside the portable case and extending the product's lifespan, but its lightweight nature also helps reduce the overall weight of the portable case, enhancing portability and saving transportation costs. More importantly, both the case body and the lid are made of food-grade polypropylene (PP) material, which meets safety standards. Even if a user accidentally licks the case body or lid while retrieving items such as the nicotine pouch stored inside, it will not cause harm to human health, fundamentally ensuring the safety of use. In addition, food-grade polypropylene (PP) material is easy to process and mold, meeting diverse structural design needs, providing a material basis for the precise manufacturing of components such as guide structures, further ensuring the stable implementation of the one-handed push-pull opening and closing function.

[0008] Optionally, the guide structure includes a groove extending along the length of the box and a slider disposed on the cover, the slider forming a sliding engagement with the groove, and the sliding stroke of the slider being limited within the length range of the groove.

[0009] By adopting the above technical solutions, the relative movement trajectory of the lid and the box can be precisely regulated, effectively avoiding shaking, deviation, or jamming during opening and closing, and ensuring the smoothness and stability of single-handed push-pull operation. This structural design makes the opening and closing stroke of the lid controllable, preventing the lid from being pulled too open and detaching from the box, and also enabling multi-level opening and closing adjustment to meet users' needs for different opening sizes. At the same time, the tight cooperation between the slide and the slider enhances the sealing performance when the portable box is closed, effectively preventing items such as nicotine pouches stored inside from getting damp, oxidized, dusty, or scattered, further improving the practicality and reliability of the product.

[0010] Optionally, the closed end of the slide is provided with a first anti-reverse member. When the slider slides to the closed end of the slide, the first anti-reverse member engages with the slider to provide a locking force in the closed state.

[0011] By adopting the above technical solution, the lid of the portable case can be effectively prevented from opening accidentally during daily carrying, placement, or when subjected to external impact or friction, thus preventing items such as nicotine pouches stored inside from falling out or being lost. The locking force provides users with clear feedback on closure, enhancing the sense of confirmation during use. At the same time, the snap-fit ​​design allows users to unlock the case with only moderate external force, ensuring both ease of opening and closing and achieving a balance between preventing accidental opening and easy opening in one-handed operation scenarios, significantly improving product safety and user experience.

[0012] Optionally, the inner wall of the slide is provided with a first limiting protrusion, and the corresponding position of the slider is provided with a second limiting protrusion; when the slider slides to the closed position, the first limiting protrusion and the second limiting protrusion engage with each other to provide additional closing force.

[0013] By adopting the above technical solution, the stability of the portable case's closed state can be further enhanced on the basis of the first locking mechanism, effectively resisting greater external impacts and preventing the lid from opening due to violent shaking or squeezing, thus providing more reliable protection for items such as nicotine pouches stored inside. The presence of additional closing force not only improves the sealing performance of the portable case and reduces the risk of internal items getting damp, dusty, or oxidized, but also provides users with more obvious closing feedback, enhancing the sense of confirmation and user experience when operating with one hand. At the same time, while ensuring a high-strength closing effect, this design can still be opened with moderate external force, balancing safety and convenience, and meeting the dual needs of the portable case for sealing and ease of opening and closing in different usage scenarios.

[0014] Optionally, a second stop is provided at the end of the slide away from the first stop, and a clearance groove is provided on the slider. The second stop abuts against the end of the clearance groove to prevent the cover from detaching from the box.

[0015] By adopting the above technical solution, the maximum stroke of the lid when it is opened can be precisely limited, effectively preventing the lid from separating from the box due to excessive sliding of the slider, and avoiding the scattering or loss of items such as nicotine pouches stored inside due to the lid falling off. This structural design ensures that the lid can be fully opened for easy access to items, while providing reliable anti-detachment protection for the portable box through the anti-reverse limiting function, enhancing the safety and stability of the product during use. In addition, the cooperation between the clearance groove and the second anti-reverse component allows the lid to flexibly adjust the opening size within the opening stroke to meet the needs of users in different retrieval scenarios, and the limiting feedback when it comes into contact can help users accurately control the degree of opening and closing, further improving the convenience and experience of one-handed operation.

[0016] Optionally, the cover is made of translucent polypropylene material, allowing the product inventory inside the carrying case to be observed through the cover.

[0017] By adopting the above technical solutions, the inconvenience caused by not being able to keep track of the remaining quantity in a timely manner is effectively avoided, helping users plan the replenishment or replacement time in advance and improving the continuity of use. This visual design eliminates the need for frequent opening and closing of the box, reducing the contact between the internal items and the external environment, reducing the risk of moisture, dust, and contamination, and extending the product's shelf life. At the same time, the light-transmitting design can also provide users with clear visual feedback, enhancing the interactive experience during product use. Especially when operating with one hand, the ability to check the quantity without opening the box further improves the practicality and convenience of the portable box.

[0018] Optionally, the cover is provided with an operating groove.

[0019] By adopting the above technical solutions, a precise and comfortable force application point can be provided for users to push and pull the lid with one hand. It conforms to the ergonomic design, effectively avoids hand slippage or force deviation, and improves the stability and convenience of operation. The presence of the groove increases the contact area between the fingers and the lid, disperses the pressure when pushing and pulling, and reduces hand fatigue caused by prolonged use. It is especially suitable for scenarios where items such as nicotine pouches in the portable case are frequently accessed. At the same time, the unique shape of the operating groove can also be used as part of the product's appearance design, enhancing the portable case's recognizability and aesthetics, and achieving an organic combination of function and appearance.

[0020] Optionally, the operating groove is provided with multiple friction contacts.

[0021] By adopting the above technical solutions, the friction between the fingers and the lid can be significantly increased, effectively preventing slippage during one-handed pushing and pulling of the lid. Even when hands are wet or dirty, the stability and reliability of operation can still be ensured. These friction points provide clear tactile feedback, helping users to accurately perceive the magnitude and direction of force applied, and achieve more precise opening and closing control. At the same time, the design of the friction points further optimizes the human-computer interaction experience, enhancing the practicality of the portable case while improving the user's comfort and convenience during use, and meeting the needs of one-handed operation in different usage scenarios.

[0022] Optionally, a baffle extends from the rear of the box body. The baffle is used to prevent the contents from falling out of the gap at the rear of the box body when the lid slides open relative to the box body. The baffle is arranged perpendicular to the length direction of the box body.

[0023] By adopting the above technical solution, and by setting a baffle perpendicular to the length of the box at the rear of the box, when the lid slides open relative to the box to create a gap, the baffle can effectively prevent the contents such as nicotine pouches from falling out of the gap at the rear of the box, avoiding accidental leakage or loss of the contents or affecting the tidiness of the usage scenario, improving the portable box's ability to store and protect the internal items, ensuring the stability and reliability of the product during use, optimizing the user experience, and solving practical usage problems caused by structural gaps.

[0024] In summary, this application has at least the following beneficial effect:

[0025] 1. By adopting the above technical solution, users can quickly and conveniently open and close the portable case without using both hands, greatly improving the convenience and efficiency of use, especially suitable for scenarios where users are busy with one hand. Both the case body and the lid are made of food-grade polypropylene (PP) material. This material not only has good chemical stability, impact resistance, and wear resistance, effectively protecting the items inside the portable case and extending the product's lifespan, but its lightweight nature also helps reduce the overall weight of the portable case, enhancing portability. More importantly, the food-grade PP material meets safety standards, so even if users accidentally lick the case body or lid while retrieving items such as the nicotine pouch stored inside, it will not cause harm to human health, fundamentally ensuring safety during use.

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] In this embodiment, refer to Figures 1-7 A portable case with a one-handed push-pull opening and closing mechanism includes a case body 1 and a lid 2. A sliding guide structure 3 is provided between the case body 1 and the lid 2, allowing for one-handed push-pull opening and closing. This opening and closing method is more convenient than traditional two-handed operation, especially suitable for scenarios where using both hands is inconvenient, greatly improving usability. Both the case body 1 and the lid 2 are made of food-grade polypropylene (PP) material. Food-grade means it meets relevant national or international standards (such as China's GB4806.7, the US FDA 21 CFR 177.1520, and the EU EC 10 / 2011). This material has undergone professional testing and certification, meeting oral safety standards, and is non-toxic and harmless, suitable for direct contact with food or oral slow-release products such as tobacco cartridges, nicotine cartridges, nicotine pouches, nicotine candies, and herbal biological products, ensuring full safety in use. Meanwhile, food-grade polypropylene (PP) material is biodegradable and recyclable, effectively reducing environmental pollution and aligning with current green environmental protection concepts. It meets product functionality requirements while also considering sustainable development goals. Preferably, a single-handed push-pull opening portable case has a depth of 21±0.5mm, a length of 85±1mm, and a width of 50±1mm. This size range is designed based on ergonomic principles and actual manufacturing processes: a depth tolerance of ±0.5mm ensures stable storage of contents (such as tobacco cartridges and nicotine pouches) while meeting the precision requirements of injection molding; a length and width tolerance of ±1mm balances hand grip comfort and mold production efficiency, ensuring that different batches of products can adapt to the grip curvature of most users' hands while still allowing for a natural finger contact with the sides of the case and easy, stable one-handed operation. Furthermore, this dimensional tolerance range effectively avoids increased costs due to excessive pursuit of high precision, maximizing product cost-effectiveness while ensuring performance.

[0038] Specifically, the guide structure 3 includes a groove 31 extending along the length of the box body 1 and a slider 32 mounted on the lid 2. The groove 31 is arranged along the length of the box body 1. Its structural feature can be a groove with a certain depth and width machined into the side of the box body 1, made of food-grade polypropylene (PP). This material provides good wear resistance and strength. In practical applications, the groove 31 can also be made of aluminum alloy, which is more robust and durable, able to withstand greater friction and impact. The slider 32 is mounted on the lid 2. It can be a protruding structure integrally molded onto the lid 2 using injection molding, also made of food-grade polypropylene (PP), and can be rectangular or trapezoidal in shape. The slider 32 can also be made of nylon, which provides good self-lubrication, making sliding smoother. The slider 32 and the groove 31 form a sliding fit, and the sliding stroke of the slider 32 is limited within the length of the groove 31, ensuring that the lid 2 does not detach from the box body 1 during sliding. For example, when the slider 32 slides to one end of the groove 31, the slider 32 cannot continue to slide because the end of the groove 31 blocks it, thus limiting the sliding stroke.

[0039] The specific description details the combination logic and effect of the slide groove 31 and slider 32 that make up the guide structure 3. The slider 32 slides within the slide groove 31, allowing the cover 2 to move along the length of the box 1, thus realizing the opening and closing function of the portable box. This effect occurs because the slide groove 31 provides a track for the slider 32, restricting its direction of movement. The slider 32 is connected to the cover 2, causing it to move together.

[0040] Specifically, the closed end of the slide 31 is provided with a first stop 4. The first stop 4 can be a semi-cylindrical protrusion, which is fixed to the closed end of the slide 31 by injection molding and is made of food-grade polypropylene (PP) material. The first stop 4 has a certain degree of elasticity. When the slider 32 slides to the closed end of the slide 31, the first stop 4 will lock the slider 32, providing a locking force in the closed state and preventing the cover 2 from opening accidentally. The first stop 4 can also be a rubber protrusion, which has good flexibility and friction, and can also play a locking role.

[0041] The cooperation between the first anti-reverse component 4 and the slider 32 effectively prevents the cover 2 from opening automatically when closed, ensuring the sealing and stability of the portable case. When the slider 32 approaches the first anti-reverse component 4, the elasticity or friction of the first anti-reverse component 4 will lock the slider 32 in place. Only by applying a certain external force can the slider 32 be disengaged from the first anti-reverse component 4, thereby opening the cover 2.

[0042] Specifically, a first limiting protrusion 5 is provided on the inner wall of the slide groove 31, and a second limiting protrusion 6 is provided at the corresponding position of the slider 32. The first limiting protrusion 5 and the second limiting protrusion 6 can be small protrusions formed by injection molding at the corresponding positions of the slide groove 31 and the slider 32, and the material is food-grade polypropylene (PP). When the slider 32 slides to the closed position, the first limiting protrusion 5 and the second limiting protrusion 6 engage with each other to provide additional closing force. This design further enhances the stability of the carrying case in the closed state and prevents the lid 2 from loosening. In practical applications, the first limiting protrusion 5 and the second limiting protrusion 6 can also be made of silicone. Silicone limiting protrusions have better elasticity and cushioning performance, which can reduce wear during engagement.

[0043] The interlocking effect of the first limiting protrusion 5 and the second limiting protrusion 6 increases the resistance in the closed state, making it more difficult for the cover 2 to be opened accidentally. This is because when the two are interlocked, the friction and elasticity between them must be overcome to open the cover 2.

[0044] Specifically, a second stop 7 is provided at the end of the slide groove 31 away from the first stop 4, and a corresponding clearance groove 8 is provided on the slider 32. The second stop 7 can be a metal block, fixed to the end of the slide groove 31 by a hot-melt process, and is made of stainless steel. The stainless steel block has high hardness and corrosion resistance, and can be used for a long time. The clearance groove 8 is a groove opened on the slider 32 to avoid the second stop 7. When the slider 32 slides to a position close to the second stop 7, the second stop 7 will abut against the end of the clearance groove 8 to prevent the cover 2 from detaching from the box 1.

[0045] The combination of the second anti-reverse component 7 and the relief groove 8 effectively prevents the cover 2 from detaching from the box body 1 during opening, ensuring the normal use of the portable box. When the slider 32 slides to its limit position, the second anti-reverse component 7 contacts the end of the relief groove 8, preventing the slider 32 from continuing to slide, thereby preventing the cover 2 from separating from the box body 1.

[0046] Specifically, both the lid 2 and the box 1 can be made of transparent, semi-transparent, or opaque food-grade polypropylene material, depending on the requirements. Preferably, the lid 2 is made of light-transmitting food-grade polypropylene material. This material has semi-transparent properties, allowing users to directly observe the product level inside the portable box and replenish it promptly. Meanwhile, the box 1 also features a semi-transparent design, effectively protecting the privacy of the products inside while still meeting the user's need to quickly check the status of the items, avoiding the inconvenience caused by complete opacity. Furthermore, if users have higher requirements for privacy or light blocking, both the lid 2 and box 1 can be made of opaque material; if the ultimate visibility is desired, both can be made of transparent material to suit different usage scenarios and personalized needs.

[0047] The advantage of using translucent polypropylene material for the cover 2 is that it ensures both the strength and environmental performance of the cover 2, while allowing users to clearly see the product inside. Compared to the traditional opaque cover 2, the translucent cover 2 is more user-friendly and improves the user experience.

[0048] Specifically, the cover 2 has an operating groove 9. The operating groove 9 can be a recessed area formed on the top of the cover 2 through an injection molding process, and the material is food-grade polypropylene (PP). Its function is to facilitate the user to push the cover 2 with their fingers, increasing the friction between the fingers and the cover 2. The shape of the operating groove 9 can be elliptical or rectangular, etc.

[0049] The design of the operating groove 9 makes it easier for users to apply force when operating with one hand, making it easier to push the cover 2. For example, when the user's finger is placed in the operating groove 9, the shape of the groove and the friction allow the finger to better control the movement of the cover 2.

[0050] Specifically, the operating groove 9 is provided with multiple friction contacts 10. The friction contacts 10 can be small protrusions formed within the operating groove 9 through laser engraving or injection molding, and are made of food-grade polypropylene (PP) material. These friction contacts 10 further increase the friction between the finger and the operating groove 9, making operation more stable. The friction contacts 10 can also be made of silicone, which offers better softness and friction.

[0051] The combination of friction contact 10 and operating groove 9 significantly improves the friction and stability when the user operates the cover 2, preventing the finger from slipping when pushing the cover 2. When the finger contacts friction contact 10, the presence of friction contact 10 increases the contact area and friction between the finger and operating groove 9, thereby achieving more precise and stable operation.

[0052] A baffle 11 extends from the rear of the box body 1. The baffle 11 prevents the contents from falling through the gap at the rear of the box body 1 when the lid 2 slides open relative to the box body 1. The baffle 11 is positioned perpendicular to the length of the box body 1. By providing a baffle 11 perpendicular to the length of the box body 1 at the rear, when the lid 2 slides open relative to the box body 1, the baffle 11 effectively prevents contents such as nicotine pouches from falling through the gap at the rear of the box body 1. This avoids accidental leakage or loss of contents or affecting the tidiness of the usage environment, improves the portable box's ability to store and protect internal items, ensures the stability and reliability of the product during use, optimizes the user experience, and solves practical usage problems caused by structural gaps.

[0053] The implementation principle of this embodiment is as follows: The single-handed push-pull opening and closing portable case of this embodiment achieves single-handed push-pull opening and closing through the guide structure 3, greatly improving the convenience of use. The case body 1 and the lid 2 are made of food-grade polypropylene (PP) material, which is both environmentally friendly and suitable for storing oral slow-release products. The design of the first anti-reverse component 4, the first limiting protrusion 5, the second limiting protrusion 6, and the second anti-reverse component 7 ensures the sealing, stability, and safety of the portable case. The light-transmitting lid 2 allows users to easily observe the internal product level, while the operating groove 9 and the friction contact point 10 further optimize the user's operating experience. Compared with the existing round boxes, the portable case of this embodiment has significantly improved and enhanced in terms of ease of use and environmental friendliness, and has strong practicality and market competitiveness.

[0054] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
