[0002] In modern life and work, simple handbags and shoulder bags made of soft plastic are commonly used. These storage bags are very suitable for daily use and also for outdoor use. Storage bags used outdoors generally need to be large in capacity, easy to access items, and able to protect the contents. The drawback of existing technology is that simple storage bags made of soft plastic have a very limited load-bearing capacity. If the load-bearing limit is exceeded, the bottom is very easy to break. Their lifespan and range of use are very limited. In addition, they cannot achieve dry and wet separation in the field of fishing bags. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a storage bag with an inner and outer double-bag structure. The inner and outer double-bag structure utilizes a strap structure to increase the structural strength of the side and bottom of the bag, greatly increasing its load-bearing capacity. The combination of mesh bags and non-mesh bags allows for the separation of dry and wet items.

Detailed Implementation
[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0025] like Figures 1 to 3 As shown, this embodiment discloses a double-bag combined storage bag, including an outer bag 1 and an inner bag 2. The structure and manufacturing method of these two bags are as follows: the outer bag 1 is made of soft plastic, namely PVC, EVA, PU, TPU, and other polar plastic materials. One or more of these materials are fed into a blow molding machine according to requirements, and a waterproof thermoplastic resin plastic preparation process is used to make it into a sheet. Then, the sheet is high-frequency welded to form a... Figure 3 The outer bag 1 structure shown;
[0026] The inner bag is made in an extruder. It is made by feeding polyethylene, polyester and polypropylene filaments into a molten state and then extruding them through a die into a mesh structure sheet. The mesh structure sheet is then used to make a grid-like inner bag 2.
[0027] like Figure 3 As shown, the outer bag 1 has an outer bag connecting hanger 4 near the bag opening 3. The outer bag connecting hanger 4 is perforated and heat-fused onto the structure of the outer bag 1. The outer bag connecting hanger 4 has two sides, as described below: The outer side has a carrying loop 9 on the outer wall of the outer bag 1, and a carrying loop 10 is connected to the carrying loop 9; The inner side has Velcro 11 and magnetic snap 12 inside the outer bag 1.
[0028] The main function of the outer bag connecting bracket 4 is to provide a carrying strap 10 for the outer bag 1 external handle component, and to provide a structure inside the outer bag 1 that connects to the inner pocket 2, including an outer bag inner Velcro 11 and an outer bag inner magnetic snap 12.
[0029] like Figure 1-3As shown in Figure 5, the inner pocket 2 is provided with an inner pocket connecting bracket 6 at the pocket opening 5. An inner handle strap 7 is provided upward on the inner pocket connecting bracket 6. The inner handle strap 7 provides convenient one-handed operation when the inner pocket 2 is a single bag. Furthermore, the inner pocket connecting bracket 6 is used as the center of gravity and connection point. The inner handle strap 7 will be combined with the inner bottom pocket strap 8 provided downward on the inner pocket connecting bracket 6 to form a whole.
[0030] like Figure 2-3 As shown, the inner pocket 2 is inserted into the outer pocket opening 3 of the inner pocket 2, and the inner pocket connecting bracket 6 of the inner pocket 2 is connected to the outer pocket connecting bracket 4, and so on. Figure 4 As shown, the inner bottom pocket strap 8 extends downward from the front of the outer bag 1, around the bottom of the outer bag 1, to the back of the outer bag 1. Then, the inner pocket female buckle at the head of the inner bottom pocket strap 8 will be fastened together with the inner pocket female buckle of the outer bag, thus connecting the outer bag 1 and the inner pocket 2. When disassembling, the two inner pocket female buckles can be separated directly.
[0031] The structure of the inner bottom pocket strap 8 connecting to the bottom of the outer bag 1 greatly enhances the load-bearing capacity of the outer bag, transferring stress from the bottom to the outer bag connecting bracket and then to the inner handle strap 7 and inner pocket 2, and then from the side to the inner pocket connecting bracket 6 of the inner pocket 2, providing load-bearing force in both the longitudinal and lateral directions.
[0032] Besides being very useful in daily life, this bag is also great for carrying items. The inner and outer pockets can be used together to lift heavy objects, and the two pockets can be used separately to help us carry more items. When we need to retrieve something, if the bag is not transparent, we have to search for a long time, but the mesh inner pocket allows the items to be directly seen and easily taken out.
[0033] Another important use case for this bag is fishing. You put water in the outer bag and put the live fish you catch in the inner bag. The live fish can also come into contact with water. If the live fish are active, they will be restrained by the inner bag, which helps the angler transport the fish. When the fish arrives at the transport location, you can simply take out the inner bag, and the water in the inner bag will separate from the water in the outer bag. In this way, we have achieved dry and wet separation.
[0034] Preferably, the outer bag connecting bracket 4 is provided with an outer bag female buckle 13 above or below the lifting rope ring 9, and the inner lower pocket bottom strap is provided with two sets, one set on the front and one set on the back of the inner pocket 2. In extreme cases, a set of guide strap rings 17 that are tied to the bottom of the inner lower pocket can be added to help with load-bearing, and the outer bag female buckle serves as a connecting assembly structure.
[0035] Preferably, the inner pocket connecting bracket 6 includes an inner pocket female buckle 14, an inner pocket inner Velcro 15, and / or an inner pocket inner magnetic snap 16. These are the connecting structures of the inner pocket connecting bracket. The inner pocket female buckle corresponds to the buckle on the bottom strap of the inner lower pocket, while the inner pocket inner Velcro and inner pocket inner magnetic snap correspond to the outer pocket inner Velcro and outer pocket inner magnetic snap, used to fix the position of the inner pocket and the connection between the two pockets.
[0036] Example 2, as Figure 4 As shown, based on Embodiment 1, the bottom of the outer bag 1 is provided with a guide belt loop 17. The guide belt loop mainly helps the inner bottom pocket strap pass through and fixes its position. The bottom of the inner pocket 2 is provided with a bottom zipper 18. This allows items to be taken directly from the bottom of the inner pocket. Lateral limiting straps 19 are provided between the guide belt loops 17. This further helps to fix the position of the inner bottom pocket strap and strengthens the lateral load-bearing capacity of the bottom.
[0037] Preferably, the inner bag 2 can also be made by directly weaving or extruding polyethylene and polypropylene yarns into a bag structure.
[0038] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
