Abstract
Description
Technical Field
[0001] This application relates to the field of plastic product technology, and in particular to a detachable environmentally friendly protective sleeve. Background Technology
[0002] Protective cases are an indispensable part of modern industrial products, widely used in electronic devices, tools, and various consumer goods. To meet the needs of different application scenarios, manufacturers typically use composite materials of hard and soft rubber to manufacture these protective cases. Hard rubber is used as the basic structure of protective cases due to its excellent heat resistance, mechanical properties, and electrical insulation properties; soft rubber, on the other hand, provides additional cushioning and comfort due to its softness and durability, making the product both sturdy and flexible.
[0003] However, while this combination brings versatility to the product, it also presents challenges for recycling. Traditional physical recycling methods, such as crushing, washing, and granulation, often fail to effectively separate the hard and soft adhesives when processing these composite materials. This not only limits the reuse rate of the material but may also affect the quality of the recycled material. Furthermore, although chemical recycling can theoretically decompose the two materials through specific chemical reactions, its practical application suffers from numerous disadvantages, including high costs, low efficiency, and potential environmental problems.

[0030] Protective cases are an indispensable part of modern industrial products, widely used in electronic devices, tools, and various consumer goods. To meet the needs of different applications, manufacturers often use composite materials of hard and soft rubber to manufacture these protective cases. However, while this combination brings versatility to the product, it also presents challenges for recycling. Traditional physical recycling methods, such as crushing, washing, and granulation, often fail to effectively separate the hard and soft rubber when processing these composite materials. This not only limits the reuse rate of the material but may also affect the quality of the recycled material. Furthermore, although chemical recycling can theoretically decompose the two materials through specific chemical reactions, its practical application suffers from many disadvantages, including high costs, low efficiency, and potential environmental problems.
[0031] In view of this, this application provides a detachable environmentally friendly protective sleeve, comprising: a hard plastic protective shell and at least one soft plastic sleeve fitted onto the side of the hard plastic protective shell; the soft plastic sleeve has an adhesive strength of 0.5 to 2.5 N. The hard plastic protective shell, serving as the main supporting part of the protective sleeve, possesses high strength and good wear resistance, effectively resisting external physical impacts such as collisions and compression, ensuring that the protected product inside remains intact in the face of various unexpected situations. The soft plastic sleeve, fitted onto the side of the hard plastic protective shell (e.g., on the inner side), provides an additional buffer layer while tightly adhering to the surface of the protected product, reducing scratches or wear that may be caused by direct contact with the hard plastic shell. Furthermore, the soft plastic sleeve is made of a material with low adhesive strength; therefore, the two can be easily separated by certain physical means (such as tension or torque), making the protective sleeve more convenient to disassemble and ensuring that the structural integrity of the protective sleeve is not damaged during the separation process, so that it can be reused after recycling.
[0032] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.
[0033] This application provides a detachable environmentally friendly protective sleeve 100, as shown in the following embodiments. Figure 1 and 2 The detachable environmentally friendly protective cover 100 includes: a hard plastic protective shell 110 and at least one soft plastic sleeve 120 sleeved on the side of the hard plastic protective shell 110; the adhesiveness of the soft plastic sleeve 120 is 0.5 to 2.5 N.
[0034] Optionally, the adhesive strength of the soft rubber sleeve 120 can be 0.5N, 0.6N, 0.7N, 0.8N, 0.9N, 1N, 1.1N, 1.2N, 1.3N, 1.4N, 1.5N, 1.6N, 1.7N, 1.8N, 1.9N, 2N, 2.1N, 2.2N, 2.3N, 2.4N, or 2.5N. When the adhesive strength of the soft rubber sleeve 120 is between 0.5N and 2.5N, the hard rubber protective shell 110 and the soft rubber sleeve 120 can be easily separated by certain physical means (such as tension or torque).
[0035] Optionally, the side can be an inner side and / or an outer side, wherein the inner side can be the side of the hard plastic protective shell 110 close to the protected product, and the outer side can be the side of the hard plastic protective shell 110 away from the protected product.
[0036] Optionally, the soft rubber sleeve 120 can be fitted onto the inside and / or outside of the hard rubber protective shell 110.
[0037] In one feasible embodiment, the separation strength between the hard plastic protective shell 110 and the soft plastic sleeve 120 is 4 to 10 N.
[0038] Optionally, the separation strength between the hard plastic protective shell 110 and the soft plastic sleeve 120 can be 4N, 4.5N, 5N, 5.5N, 6N, 6.5N, 7N, 7.5N, 8N, 8.5N, 9N, 9.5N, or 10N. When the separation strength is in the range of 4 to 10N, it indicates that the bonding force between the hard plastic protective shell 110 and the soft plastic sleeve 120 is moderate. On the one hand, within this strength range, it is sufficient to ensure that the soft plastic sleeve 120 can fit tightly against the hard plastic protective shell 110 during daily use and will not easily fall off due to slight vibration or friction. At the same time, the physical properties of the materials may fluctuate with changes in temperature and humidity. Within this separation strength range, even if there are slight changes in the environment, the bonding force between the soft plastic sleeve 120 and the hard plastic protective shell 110 can remain at a relatively stable level, neither easily falling off nor being too tight. On the other hand, applying a relatively small external force is sufficient to overcome the interfacial bonding force, causing the hard plastic protective shell 110 and the soft plastic sleeve 120 to separate, thereby easily separating the soft plastic sleeve 120 from the hard plastic protective shell 110. After separation, refer to... Figure 2 This ensures that the hard plastic protective shell 110 or the soft plastic sleeve 120 will not suffer unnecessary physical damage during the separation process, thus maintaining the integrity of the product.
[0039] In one feasible embodiment, the material of the hard plastic protective case 110 includes: polycarbonate, acrylonitrile-butadiene-styrene copolymer, polyamide, polyethylene terephthalate, polyvinyl chloride, or polystyrene. The aforementioned hard plastic materials possess excellent strength and hardness, providing a robust protective barrier for the product. These materials effectively resist external impacts, scratches, and pressure, significantly reducing the risk of damage caused by accidental drops or collisions during daily use. The hard plastic case also exhibits extremely high abrasion resistance, resisting scratches or deformation even with prolonged use, maintaining the integrity and aesthetics of the protective case for an extended period. Furthermore, the aforementioned hard plastic materials typically possess good chemical stability, remaining unaffected by environmental factors such as temperature and humidity. This means that the protective case 100 can maintain stable protective performance under various environmental conditions, providing reliable protection for the user.
[0040] Alternatively, polycarbonate (PC) is a very strong and transparent plastic with excellent impact resistance and heat resistance. It is often used to manufacture protective cases for high-end electronic products, such as smartphone and tablet cases.
[0041] Alternatively, acrylonitrile-butadiene-styrene copolymer (ABS) is a tough, easy-to-process thermoplastic with good mechanical properties and chemical resistance. It is widely used in the manufacture of casings for consumer electronics, automotive parts, and toys.
[0042] Alternatively, polyamides (PAs) are known for their high strength, abrasion resistance, and self-lubricating properties. They are suitable for applications requiring high mechanical strength and dimensional stability, such as tool handles or protective housings for sports equipment.
[0043] Alternatively, polyethylene terephthalate (PETG) is a modified PET plastic with better transparency, toughness, and processability. It is suitable for protective case designs that require a certain level of transparency and is easier to mold than standard PET.
[0044] Alternatively, polyvinyl chloride (PVC) is a lightweight, durable, and chemical-resistant plastic with high tensile strength and modulus of elasticity. It is commonly used to manufacture protective shells for food containers and other everyday items because it meets food safety standards.
[0045] In one feasible embodiment, the material of the soft rubber sleeve 120 includes: silicone rubber, styrene-ethylene / butene-styrene block copolymer, polyurethane, acrylic rubber, ethylene-vinyl acetate copolymer, styrene block copolymer, or polypropylene. These materials possess excellent cushioning and shock absorption capabilities, effectively absorbing the impact force generated when the product is accidentally dropped, thereby protecting the protected product from damage. Simultaneously, the soft rubber sleeve 120 material exhibits good flexibility and elasticity, allowing it to closely conform to the edges and corners of the product, providing comprehensive wrapping and protection without affecting the normal use and operation of the product.
[0046] Alternatively, silicone rubber has excellent resistance to high and low temperatures and can maintain its elasticity and softness over a wide temperature range.
[0047] Alternatively, styrene-ethylene / butene-styrene block copolymers (SEBS) can provide good tactile feel and flexibility, while also possessing high mechanical strength.
[0048] Alternatively, polyurethane (PU) has excellent abrasion resistance and can withstand large stretching without easily breaking.
[0049] Alternatively, acrylic rubber (ACM) has strong resistance to natural factors such as sunlight and ozone, making it suitable for applications that require long-term exposure.
[0050] Alternatively, ethylene-vinyl acetate copolymer (EVA) can effectively absorb impact forces and is suitable as a shock-absorbing protective layer.
[0051] Alternatively, styrene block copolymers (SBCs) have good processing properties and are easy to process into various shapes and thicknesses, making them suitable for customized designs.
[0052] Alternatively, polypropylene (PP) has good chemical stability and is lightweight and strong.
[0053] In one possible embodiment, the hard plastic protective shell 110 is provided with a receiving portion 111 for placing the protected product; while the soft plastic sleeve 120 is fitted on the side of the hard plastic protective shell 110 near the protected product.
[0054] Optionally, the protected product can be a mobile phone, tablet, computer, watch, electronic product, auto parts, toy, tool handle, sports equipment, daily necessities, etc., and the protective case 100 can be set according to the shape of the protected product.
[0055] In one feasible embodiment, the side of the hard plastic protective shell 110 is provided with a groove 114 that matches the shape of the soft plastic sleeve 120. The groove 114 is used to fix the soft plastic sleeve 120, thereby preventing the soft plastic sleeve 120 from falling off during use.
[0056] In one possible embodiment, the back panel of the hard plastic protective case 110 is provided with a first opening 112 that matches the camera of the protected product.
[0057] In one possible embodiment, at least one side of the hard plastic protective shell 110 is provided with a protrusion 113 corresponding to at least one button of the protected product.
[0058] Optionally, at least one side of the hard plastic protective case 110 is provided with a protrusion 113 corresponding to the volume button and power button of the protected product.
[0059] In one possible embodiment, at least one side of the hard plastic protective shell 110 is provided with a second opening 115 that matches at least one functional interface of the protected product.
[0060] In one feasible embodiment, the second opening 115 includes at least one of the following: a charging port, a USB interface port, a headphone port, and a voice port.
[0061] In this embodiment, a detachable environmentally friendly protective sleeve 100 is provided, comprising: a hard plastic protective shell 110 and at least one soft plastic sleeve 120 fitted on the side of the hard plastic protective shell 110; the soft plastic sleeve 120 has an adhesive strength of 0.5 to 2.5 N. The hard plastic protective shell 110 serves as the main supporting part of the protective sleeve 100, possessing high strength and good wear resistance, effectively resisting external physical impacts such as collisions and compressions, ensuring that the protected product inside remains intact in the face of various unexpected situations. The soft plastic sleeve 120 is fitted on the side of the hard plastic protective shell 110 (e.g., on the inner side). In this case, the soft plastic sleeve can provide an additional buffer layer while tightly adhering to the surface of the protected product, reducing scratches or wear that may be caused by direct contact with the hard plastic shell. In addition, the soft rubber sleeve 120 is made of a material with low viscosity. Therefore, the two can be easily separated by certain physical means (such as tension, torque, etc.), making the protective sleeve 100 easier to disassemble and ensuring that the structural integrity of the protective sleeve 100 is not damaged during the separation process so that it can be reused after recycling.
