Description

Technical Field

[0001] This utility model relates to the field of leak-proof bag technology, specifically a leak-proof valve bag. Background Technology

[0002] Currently, valve bags are widely used in the packaging and transportation field for the containment and handling of various powdery and granular materials. However, traditional valve bags have several drawbacks: First, their bottom structure is usually flat, resulting in poor stability when placed, especially when filled with heavy objects, making them prone to tipping over. They are also inconvenient to fold and store, occupying a significant amount of storage and transportation space. Second, their sealing performance is limited; when the transportation environment is humid, the materials inside the bag are prone to moisture absorption and deterioration, affecting product quality. Third, their functionality is limited, lacking insulation and environmental protection features, failing to meet the packaging needs of materials with special storage requirements, such as food and chemical raw materials. While improvements in existing technologies can solve some problems, there is still considerable room for optimization in terms of structural integration, practicality, and environmental friendliness. There is an urgent need to develop a multifunctional, easy-to-store leak-proof valve bag.

[0003] Publication number: CN213769663U. By improving the structure of the equipment, the valve bag can be reinforced with the female and male grooves at the valve port during use, which strengthens its connection and prevents it from falling off due to external pressure, thus affecting the sealing performance of the valve bag.

[0004] To address the aforementioned issues, existing valve bags are unstable when placed, making them difficult to store and fold, and their internal structures cannot meet various needs. Therefore, we propose a leak-proof valve bag. Utility Model Content

[0028] Structural Description: Leak-proof Bag Body 1: The main body of the entire leak-proof valve bag, with an external rectangular shape and a hollow interior, used to hold various powdery and granular materials. It is the foundation for supporting other structures and the core carrier for the entire bag to achieve its various functions.

[0029] 3D base 2: Installed at the bottom of the leak-proof bag body 1, it is also hollow inside. Its main function is to increase the contact area between the bag and the placement surface, thereby improving the stability of the bag when placed and reducing the possibility of tipping over due to the heavy contents. At the same time, when not in use, the 3D base can be folded upwards to achieve the folding and storage function of the bag in conjunction with other structures.

[0030] Hollow groove 3: Set on the outer surface of the handle 4, the hollow groove increases the contact area and friction between the handle and the hand, making it more comfortable and stable for the user to carry the bag, distributing the pressure on the hand and reducing the burden on the hand.

[0031] Handle 4: Fixedly connected to both ends of the top of the leak-proof bag body 1, making it convenient for users to lift the bag and move materials. Its design allows users to easily lift the bag and is suitable for various scenarios where the bag needs to be moved.

[0032] Sealing port 5: Located at the top of the leak-proof bag body 1, it is trapezoidal in shape and has a groove at the top. The sealing port is mainly used to seal the bag opening after the material is filled, to prevent material leakage and external dust, moisture and other substances from entering the bag, so as to ensure the quality and safety of the material inside the bag.

[0033] Outer Velcro layer 6: It is fixedly connected to one end of the sealing opening 5. Its outer surface is provided with small hooks. The outer Velcro layer cooperates with the sealing opening to seal the bag opening by sticking. It is easy to operate and has a good sealing effect, which can effectively prevent material leakage and the intrusion of external impurities.

[0034] Splicing base plate 7: It is fixedly connected to the bottom of the leak-proof bag body 1. It is rectangular in shape. The splicing base plate is an important part of the fixing component. It works with the sealing sticker 8. When the bag is not in use, the three-dimensional base 2 can be folded up and connected to the splicing base plate through the sealing sticker to realize the folding and storage of the bag and reduce space occupation.

[0035] Sealing tape 8: It is fixed to the center of the outside of the splicing base plate 7. An adhesive layer is provided at one end near the splicing base plate. The sealing tape is used to connect the two ends of the splicing base plate and plays a fixing role when the bag is folded, ensuring that the folded bag remains compact and is easy to store and transport.

[0036] Waterproof layer 9: It is fixedly connected to the inside of the leak-proof bag body 1. The main function of the waterproof layer is to prevent water from penetrating into the bag, reduce material aging caused by water erosion, thereby extending the service life of the bag, and at the same time protect the material inside the bag from moisture. It is suitable for various humid environments or scenarios where water may come into contact with the bag.

[0037] Insulation layer 10: Fixedly connected inside the waterproof layer 9, the insulation layer can effectively slow down the rate at which heat dissipates from inside the bag to the outside or heat enters from outside the bag, maintain the relative stability of the temperature inside the bag, and meet the transportation and storage needs of materials with special temperature requirements, such as hot food and certain chemical raw materials.

[0038] Environmental protection layer 11: It is fixedly connected to the inside of the insulation layer 10. The outer surface is coated with an environmentally friendly material and is itself a biodegradable material. The environmental protection layer plays a protective role during use and extends the normal service life of the bag. After disposal, the biodegradable material can gradually decompose into harmless substances in the natural environment, reducing pollution to the environment and achieving the purpose of environmental protection.

[0039] Instructions for use

[0040] The sealing opening 5 at the top of the leak-proof bag body 1 is trapezoidal. In use, align the bag openings and secure them with the outer Velcro layer 6. The small hooks on the outer Velcro layer 6 firmly grip the corresponding adhesive areas, preventing leakage of the material inside the bag and preventing external dust and moisture from entering, thus providing a good seal. The waterproof layer 9 inside the leak-proof bag body 1 effectively blocks water penetration due to its waterproof properties. When the bag comes into contact with water or is in a humid environment, the waterproof layer 9 prevents water from contacting the insulation layer 10, the environmental protection layer 11, and the material inside the bag, reducing material aging caused by water erosion, extending the bag's lifespan, and protecting the material from moisture. The insulation layer 10 uses a material with low thermal conductivity, slowing down heat transfer to reduce heat loss from inside the bag and heat transfer from outside. The environmental protection layer 11 uses a biodegradable material and is coated with an environmentally friendly material. During use, environmentally friendly materials provide protection. The splicing base plate 7 and sealing sticker 8 in the fixing components work together to achieve the folding and storage function. When the bag is not in use, the three-dimensional base 2 can be folded upwards, and the adhesive layer of the sealing sticker 8 is used to connect and fix the two ends of the splicing base plate 7, so that the bag forms a compact folded state. Since the interior of the three-dimensional base 2 is hollow, it further reduces the space occupied after folding, making it easier to store and transport. The three-dimensional base 2 increases the contact area between the bag and the ground, and can provide more stable support, reducing the risk of the bag tipping over due to unstable center of gravity or external interference, ensuring the safe storage and transportation of materials. The handles 4 at both ends of the top of the leak-proof bag body 1 make it convenient for users to carry. The hollow grooves 3 on the surface of the handles 4 can increase the contact area and friction with the hands, allowing the hands to better grip the handles 4 when carrying, distributing pressure, thus making the carrying process more comfortable and stable, and reducing the burden on the hands.
