Description

Technical Field

[0001] This utility model relates to the field of glove technology, and in particular to a leak-proof film glove. Background Technology

[0002] Thin-film gloves are frequently used in fields such as medicine, scientific research, and food.

[0003] If PE gloves leak during examinations and nursing procedures, the patient's blood and bodily fluids may come into contact with the medical staff's skin through the gloves. At the same time, germs carried on the medical staff's hands may also be transferred to the patient, greatly increasing the chance of cross-infection and endangering the health of both medical staff and patients.

[0004] During food processing, handling, and packaging, leakage from PE gloves can allow sweat, dust, and other impurities from the hands to enter the food, causing contamination and failing to meet food safety and hygiene standards. This could potentially lead to discomfort or other health problems for consumers after consumption.

[0005] In chemical and biological laboratories, if PE gloves leak, external impurities and moisture may mix into the experimental samples, altering the composition and purity of the samples, affecting the accuracy of experimental data, causing deviations in experimental results, and interfering with subsequent research and analysis.

[0006] In current efforts to improve PE gloves, improving one parameter often leads to the deterioration of another. For example, increasing the molding temperature in the blow molding process in an attempt to make the glove film denser and improve its leak-proof performance may cause the material to soften excessively and the molecular chains to be damaged due to excessive temperature. This can reduce the overall strength and durability of the glove, making it more prone to breakage and leakage, thus affecting the overall performance of the product.

[0007] Therefore, despite continuous efforts to improve processes and optimize materials, current PE gloves, due to the inherent molecular structure of PE materials and cost limitations, still struggle to achieve the ideal leak-proof performance required by high-demand applications such as nitrile gloves in medical, food, and chemical industries. Leakage is still likely to occur when exposed to various complex liquids and for extended periods of protection. This application addresses these shortcomings. Utility Model Content

[0008] The purpose of this invention is to provide a leak-proof film glove that solves the problem that the leak-proof performance of gloves used in the medical, food, and chemical industries is difficult to further improve.

[0009] To solve the above problems, this utility model provides a leak-proof film glove, including an outer film layer, an absorbent material layer, and an inner film layer. The outer and inner film layers are made of waterproof polymer materials, and the absorbent material layer can absorb the leaked liquid when leakage occurs in the outer or inner film layer.

[0010] According to one embodiment of the present invention, the outer and inner layers of the film can be made of TPU (thermoplastic polyurethane), HDPE (high-density polyethylene), LDPE (low-density polyethylene), etc., and preferably PE film processed from LDPE material.

[0011] According to one embodiment of the present invention, the absorbent material layer is a PP absorbent cotton layer that has undergone hydrophilic pretreatment, which can improve the hydrophilicity of the glove. This allows the absorbent cotton to absorb any slight leakage that may occur in the outer or inner layer of the glove due to frequent hand movements, preventing liquid leakage from causing contamination or cross-infection, and improving the safety and leak-proof properties of the glove.

[0012] According to one embodiment of the present invention, an adhesive layer is provided between the absorbent material layer and the outer and inner layers of the PE film. Preferably, an acrylic adhesive suitable for both absorbent cotton and PE film materials is used. This type of adhesive has good adhesion to both materials and is environmentally friendly with a moderate drying speed.

[0013] According to one embodiment of the present invention, the amount of adhesive applied to the adhesive layer is 10~30g / m².

[0014] Preferably, the amount of adhesive applied is 15-20 g / m².

[0015] According to one embodiment of the present invention, a portion or all of the area of ​​the leak-proof film glove is composed of the outer film layer, the absorbent material layer, and the inner film layer.

[0016] According to one embodiment of the present invention, the leak-proof film glove has a wrist tightening portion.

[0017] According to one embodiment of the present invention, the wrist tightening part adopts an arc-shaped inward contraction structure.

[0018] The beneficial effects of this invention are that by combining multiple layers of materials with different properties, the inner and outer layers are made of soft and skin-friendly polyethylene material, and the middle layer contains absorbent material. The softness of the inner layer ensures the comfort of wearing the glove, while the barrier material in the middle layer acts as a barrier, effectively preventing the penetration of liquids, microorganisms, etc., greatly reducing the risk of leakage caused by external physical damage. This is the core structural basis for achieving leak-proof performance and makes a significant contribution to the overall leak-proof effect. This structural design fundamentally improves the leak-proof performance of the glove through the synergistic effect of each layer of materials. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Figure 1 Schematic diagram of the layered structure of a leak-proof film glove;

[0021] Figure 2 A schematic diagram of the overall structure of a leak-proof film glove. Detailed Implementation

[0022] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0023] A type of leak-proof film glove, such as Figure 1 It includes an outer film layer 1, a water-absorbing material layer 2, and an inner film layer 3.

[0024] The outer layer 1 and inner layer 3 of the film are made of LDPE material, which has good flexibility, transparency and processing performance, making it suitable for blow molding into films. The raw materials must be dry and free of impurities to avoid affecting subsequent processing and film quality. The outer layer 1 and inner layer 3 of the film enhance the overall strength, water resistance and barrier properties of the gloves.

[0025] The absorbent material layer 2 can absorb the leaked liquid when leakage occurs in the outer layer 1 or the inner layer 3 of the film. The absorbent material layer 2 is a PP absorbent cotton layer that has undergone hydrophilic pretreatment, which can improve the hydrophilicity of the glove. It is convenient to absorb the slight leakage that occurs in the outer or inner layer of the glove due to frequent hand movements. The absorbent cotton can absorb the leakage in time, prevent the liquid leakage from causing pollution or cross-infection, and improve the safety and leak-proof performance of the glove.

[0026] This solution employs a multi-layered protection principle. The outer membrane layer 1 serves as the first line of defense, primarily responsible for resisting external liquids and contaminants. It possesses high strength, abrasion resistance, and water resistance, enabling it to prevent large amounts of liquids, bacteria, viruses, etc., from directly harming or contaminating the hands in various harsh environments or complex operating scenarios. For example, in medical examinations, the outer membrane effectively blocks the patient's blood and bodily fluids, reducing the risk of potential cross-infection; in the industrial chemical field, it prevents the erosion and penetration of various corrosive chemical reagents and oil stains.

[0027] The absorbent material layer 2 plays a crucial role in cushioning and absorption. When the outer film suffers minor damage due to accident or when a small amount of liquid seeps in after prolonged use, the absorbent cotton in the absorbent material layer 2 can quickly absorb this seepage, preventing the liquid from spreading further to the inner film and leaking out. The loose and porous structure of the PP absorbent cotton facilitates the rapid absorption and storage of liquid, while also mitigating the impact of external pressure on the internal structure to a certain extent, enhancing the overall durability and protective stability of the glove. For example, during prolonged medical examinations, if the outer or inner layer of the glove experiences slight leakage due to frequent hand movements, the absorbent cotton can promptly absorb the leakage, preventing contamination or cross-infection.

[0028] The inner layer 3 of the membrane is primarily responsible for direct contact with the hands, prioritizing skin-friendliness, comfort, and basic water resistance. It ensures user comfort, reduces skin irritation, and prevents the seepage of small amounts of sweat and secretions under normal conditions, maintaining a relatively dry environment for the hands. It also serves as the final barrier against external liquids penetrating the hands. In scenarios where comfort is paramount, such as the assembly of delicate electronic components, the excellent tactile feel and basic protective performance of the inner membrane ensure precision and safety during operation. Even if a very small amount of liquid breaches the outer barrier, the inner membrane, in conjunction with absorbent pads, can effectively control the situation and prevent liquid contact with the hands.

[0029] At the edges and joints of the gloves, a heat-sealing process is used to seal the three-layer structure. Under appropriate temperature, pressure and time control, the inner and outer film layers and absorbent cotton are firmly fused together at the edges to form a complete sealing system, effectively preventing liquid leakage from the joints.

[0030] Preferably, an adhesive layer is provided between the absorbent material layer 2 and the outer PE film layer 1 and the inner PE film layer 3. The preferred amount of adhesive is 15-20 g / m². Too much adhesive will result in a long curing time after bonding, while too little will affect the bonding strength between the layers. By optimizing the setting to a suitable range, it is ensured that the materials of each layer are tightly bonded without delamination, forming a complete and highly sealed overall structure.

[0031] The preferred adhesive layer is an acrylic adhesive suitable for both absorbent cotton and PE film. This type of adhesive exhibits good adhesion to both materials and is also environmentally friendly with a moderate drying speed.

[0032] Optionally, the leak-proof membrane glove may consist of a PE film outer layer 1, an absorbent material layer 2, and a PE film inner layer 3, with some or all of the area being composed of a PE film outer layer 1, an absorbent material layer 2, and a PE film inner layer 3.

[0033] Preferably, the leak-proof film glove has a wrist tightening part 4, which prevents the glove from falling off.

[0034] In this embodiment, as Figure 2 The wrist tightening section 4 adopts an arc-shaped inward structure, increasing the contact area between the cuff and the wrist, making the pressure distribution more even, and improving the fit and stability. Furthermore, the cuff can be slightly narrower on the side closer to the palm to conform to the natural shape of the wrist, reducing gaps caused by wrist movements, and thus preventing the gloves from slipping off.

[0035] In other embodiments, a tightening structure, such as an elastic band or elastic elastic band, can be added and installed at the wrist tightening part 4 to cooperate with the arc-shaped inward structure to further prevent it from falling off. Optionally, a groove for installing the tightening structure can be provided at the wrist tightening part 4.

[0036] This glove is constructed using a multi-layered adhesive system of materials with varying properties. The inner and outer layers are made of soft, skin-friendly polyethylene (PE), while an absorbent cotton layer is incorporated in the middle. This structural design, through the synergistic effect of each layer, fundamentally enhances the glove's leak-proof performance. The softness of the inner layer ensures comfortable wear, while the barrier material in the middle layer acts as a barrier, effectively preventing the penetration of liquids and microorganisms. This significantly reduces the risk of leakage due to external physical damage and forms the core structural foundation for leak-proof performance, making a significant contribution to the overall leak-proof effect.

[0037] In this solution, the selection of materials for each layer considers not only their individual properties but also their compatibility and overall performance balance. This ensures excellent barrier properties without compromising the glove's flexibility and processing performance. Through material selection, the gloves not only provide leak-proof functionality but also meet diverse needs in different usage scenarios, such as the tactile feel and flexibility requirements in the medical field. This approach lays a solid foundation for improving the glove's overall performance, greatly expanding its application range, and indirectly enhancing the product's market competitiveness and practicality.

[0038] Excellent leak-proof performance: Through the comprehensive application of the above-mentioned key technologies, this leak-proof membrane glove exhibits excellent leak-proof capabilities under various harsh conditions. Experimental data shows that in protective performance tests, such as simulated chemical reagent penetration experiments, when a specific concentration of chemical reagent is applied to the glove surface, ordinary gloves show signs of penetration within 10 minutes, while the glove of this invention remains unpenetrated after 30 minutes. This indicates that the inner and outer membrane structure enhances the protective performance. Multiple sets of similar experimental data fully demonstrate the technical effectiveness of the glove of this invention in different application scenarios.

[0039] The gloves in this solution effectively prevent penetration of common liquids such as water and saline solution, as well as various organic reagents that may be encountered in medical and other fields. They provide a reliable protective barrier for users, significantly reducing the risk of cross-infection due to liquid leakage. For users, this provides reliable and predictable protection, enhancing their trust and loyalty to the product.

[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
