Description

Technical Field

[0001] This utility model relates to the field of waterproof bags, specifically a puncture-resistant waterproof bag. Background Technology

[0002] Waterproof bags, as a common packaging container, are widely used in various fields such as outdoor sports, military reconnaissance, water operations, electronic equipment protection, and emergency disaster relief. They are used to protect items from drying in humid, watery, or underwater environments.

[0003] Currently, the most common waterproof bags on the market can be divided into the following categories:

[0004] Simple bags made of polyvinyl chloride (PVC) or polyurethane (TPU) coated fabrics have a certain degree of waterproof performance, but their outer material has poor abrasion resistance and tear resistance. When used in complex environments such as jungles and reefs, they are easily punctured or torn by sharp objects such as branches and rocks, causing the overall waterproof function to fail.

[0005] Products made with thickened Oxford cloth or canvas and an internal waterproof membrane have improved abrasion resistance, but still have significant drawbacks:

[0006] First, its reinforcing structure and waterproof layer are usually just a simple lamination combination, with more flexibility than rigidity. When filled with heavy objects or subjected to external pressure or impact, the bag is prone to severe deformation, causing the internal waterproof membrane to fatigue and rupture due to excessive bending.

[0007] Secondly, the openings of these products often use a roll-top seal with a drawstring or a simple snap-on flap seal. The former is cumbersome to operate and depends on the user's strength, resulting in inconsistent sealing reliability; the latter is difficult to provide uniform and sufficient pressure throughout the entire opening, leading to unsatisfactory sealing, especially prone to leakage when exposed to water and pressure. Therefore, a puncture-resistant waterproof bag is proposed to address these issues. Utility Model Content

[0008] To overcome the shortcomings of existing technologies and solve the problems of weak puncture resistance, poor overall deformation resistance, and unreliable sealing of existing waterproof bags, this utility model proposes a puncture-resistant waterproof bag.

[0009] The technical solution adopted by this utility model to solve its technical problem is: a puncture-resistant waterproof bag, including a puncture-resistant layer, a waterproof inner layer, reinforcing ribs, a snap fastener assembly, reinforcing patches, and a pressure block.

[0010] The puncture-resistant layer includes an anti-puncture fiber cloth layer and a bottom cloth layer arranged sequentially from the outside to the inside, and the side of the bottom cloth layer facing the inside of the waterproof bag has a first groove.

[0012] The reinforcing ribs are embedded in the accommodating space formed by the first groove and the second groove.

[0013] The snap-on assembly is located at the opening of the waterproof bag to seal the opening.

[0014] The reinforcing patch is disposed on the outer surface of the puncture-resistant fiber cloth layer.

[0015] The pressure block is fixedly disposed on the outer surface of the puncture-resistant fiber cloth layer and adjacent to the opening of the waterproof bag, and the snap fastener assembly is pressed and engaged with the pressure block.

[0016] Preferably, the snap fastener assembly includes a first pressure plate and a second pressure plate rotatably connected by a hinge. The end of the first pressure plate is provided with a first outwardly protruding locking block, and the end of the second pressure plate is provided with a second outwardly protruding locking block. The first locking block and the second locking block are detachably engaged.

[0017] Preferably, when the first pressure plate and the second pressure plate are fastened together, their inner surfaces are tightly pressed against the surface of the pressure block.

[0018] Preferably, a ring is fixedly provided on the outer side wall of the first pressure plate, and the axial direction of the ring is perpendicular to the length direction of the first pressure plate.

[0019] Preferably, the edge of the waterproof film layer is fixedly connected to the inner wall of the puncture-resistant fiber cloth layer.

[0020] Preferably, the opening edge of the waterproof inner layer is provided with an inwardly folded edge, which is fixedly connected to the waterproof film layer.

[0022] Preferably, the reinforcing rib is made of an elastic material, and its cross-sectional shape is adapted to the cross-sectional shape of the accommodating space formed by the first groove and the second groove.

[0023] The advantages of this utility model are:

[0024] 1. This utility model achieves the function of resisting the impact of external sharp objects through the structural design of the anti-puncture layer composed of an anti-puncture fiber cloth layer and a bottom cloth layer, solving the problem that traditional waterproof bags are easily punctured, and improving the durability and reliability of the product.

[0025] 2. This utility model, through the structural design of reinforcing ribs embedded in the first and second grooves, achieves the functions of enhancing the rigidity of the bag and dispersing stress, solving the problem of the bag being easily deformed and causing the waterproof layer to break, and improving the product's resistance to compression and impact.

[0026] 3. This utility model achieves the functions of quick locking and surface sealing of bag opening through the structural design of the snap fastener assembly consisting of a pressure plate, a locking block and a pressure block, solving the problem of unreliability of traditional rolled edge or drawstring sealing, and improving the convenience and effectiveness of product sealing.

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses a puncture-resistant waterproof bag. (See also...) Figures 1 to 6 A puncture-resistant waterproof bag includes a puncture-resistant layer 1, a waterproof inner layer 2, reinforcing ribs 3, a snap fastener assembly 4, a reinforcing patch 5, and a pressure block 6.

[0040] The puncture-resistant layer 1 includes an anti-puncture fiber cloth layer 101 and a bottom cloth layer 102 arranged sequentially from the outside to the inside. The bottom cloth layer 102 has a first groove 103 on the side facing the inside of the waterproof bag.

[0041] Preferably, the puncture-resistant fiber cloth layer 101 can be woven from ultra-high molecular weight polyethylene fiber, aramid fiber or high-strength polyester fiber, and the bottom cloth layer 102 is polyester or nylon Oxford cloth, which is compounded with the puncture-resistant fiber cloth layer 101 by hot melt adhesive or polyurethane adhesive. The first groove 103 and the second groove 203 are formed by molding or hot pressing during the compounding process.

[0042] The waterproof inner layer 2 is disposed inside the puncture-resistant layer 1. The waterproof inner layer 2 includes a waterproof film layer 201. The side of the waterproof film layer 201 facing the puncture-resistant layer 1 is provided with a second groove 203 corresponding to the first groove 103. The edge of the waterproof film layer 201 is fixedly connected to the inner wall of the puncture-resistant fiber cloth layer 101. The opening edge of the waterproof inner layer 2 is provided with an inwardly folded edge 202. The folded edge 202 is fixedly connected to the waterproof film layer 201.

[0043] Preferably, the waterproof film layer 201 is a thermoplastic polyurethane (TPU) film or a polyvinyl chloride (PVC) film. The waterproof film layer 201 is fixed to the inner wall of the puncture-resistant fiber cloth layer 101 by high-frequency heat sealing or adhesive bonding. The rolled edge 202 is formed by folding the opening edge of the waterproof inner layer 2 inward and using a hot pressing process to fuse and fix it with its own film layer.

[0044] The reinforcing rib 3 is embedded in the accommodating space formed by the first groove 103 and the second groove 203. The reinforcing rib 3 is made of elastic material, and its cross-sectional shape is adapted to the cross-sectional shape of the accommodating space formed by the first groove 103 and the second groove 203.

[0045] Preferably, the reinforcing rib 3 is a solid or foamed TPU, silicone or EVA strip with a certain degree of elasticity and softness. The reinforcing rib 3 is fixed in the accommodating space by mechanical embedding or by local dispensing adhesive at the groove.

[0046] The snap fastener assembly 4 includes a first pressure plate 401 and a second pressure plate 403 rotatably connected by a hinge 402. The end of the first pressure plate 401 is provided with an outwardly protruding first locking block 404, and the end of the second pressure plate 403 is provided with an outwardly protruding second locking block 405. The first locking block 404 and the second locking block 405 are detachably engaged. When the first pressure plate 401 and the second pressure plate 403 are fastened, their inner surfaces are tightly pressed against the surface of the pressure block 6. A ring 406 is fixedly provided on the outer side wall of the first pressure plate 401. The axial direction of the ring 406 is perpendicular to the length direction of the first pressure plate 401. The snap fastener assembly 4 is disposed at the opening of the waterproof bag for sealing the opening.

[0047] The reinforcing patch 5 is disposed on the outer surface of the puncture-resistant fiber cloth layer 101. The reinforcing patch 5 is made of wear-resistant material and is attached and fixed to the corners and easily worn parts of the puncture-resistant fiber cloth layer 101 on the outer surface of the puncture-resistant fiber cloth layer 101.

[0048] Preferably, the reinforcing patch 5 is made of wear-resistant rubber or thickened TPU material.

[0049] The pressure block 6 is fixedly disposed on the outer surface of the puncture-resistant fiber cloth layer 101 and adjacent to the opening of the waterproof bag. The snap fastener assembly 4 is pressed and engaged with the pressure block 6. The pressure block 6 is a TPU or plastic part, which is fixed to the outer surface of the bag body by stitching or high-frequency pressing.

[0050] like Figure 6As shown, when the snap fastener assembly is engaged, the first pressure plate 401 and the second pressure plate 403 rotate around the hinge 402 until the first locking block 404 and the second locking block 405 engage and lock. At this time, the inner sides of the two pressure plates press the bag opening material tightly against the pressure block 6, forming a sealing line.

[0051] Working principle:

[0052] I. Item Placement Stage

[0053] When using, first open the opening of the waterproof bag and place the items to be stored into the interior of the waterproof inner layer 2 through the opening. The waterproof membrane layer 201 of the waterproof inner layer 2 can initially isolate the internal items from external moisture, and its edges are fixedly connected to the inner wall of the puncture-resistant fiber cloth layer 101 of the puncture-resistant layer 1 to ensure the stability of the inner layer structure.

[0054] II. Bag Sealing Stage

[0055] When closing the bag opening, the snap fastener assembly 4 is operated to achieve a seal: the first pressure plate 401 and the second pressure plate 403 of the snap fastener assembly 4 rotate through the hinge 402 to clamp the material at the bag opening in the middle, align with the pressure block 6 near the bag opening, and fix it to the outer surface of the puncture-resistant fiber cloth layer 101. Press down the pressure plate so that the first locking block 404 of the first pressure plate 401 and the second locking block 405 of the second pressure plate 403 are engaged and locked. At this time, the inner sides of the two pressure plates are tightly pressed against the surface of the pressure block 6, and in conjunction with the rolled edge 202 of the opening edge of the waterproof inner layer 2, they are folded inward and fixed with the waterproof film layer 201 to form a multiple seal, effectively preventing external moisture from entering.

[0056] III. Protection Phase During Use

[0057] When the bag is subjected to external puncture, compression or friction: the outer puncture-resistant fiber cloth layer 101 directly resists the puncture force, reducing the damage to the bag by external sharp objects. If the impact force is transmitted to the inside of the bag, the reinforcing ribs 3 between the bottom cloth layer 102 and the waterproof membrane layer 201 will absorb energy and disperse stress, preventing stress concentration from puncturing the waterproof membrane layer 201 and protecting the inner layer's sealing. The reinforcing patch 5 (made of wear-resistant material) on the outer surface of the puncture-resistant fiber cloth layer 101 covers the corners and easily worn parts, reducing wear during daily use and extending the bag's service life. In addition, the ring 406 on the first pressure plate 401 can be easily hung or carried, improving ease of use.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
