Technical Field

[0001] This utility model relates to the field of shopping bag technology, and in particular to a shopping bag with an automatic sealing function. Background Technology

[0002] Shopping bags, as the name suggests, are bags used for shopping. The main types of shopping bags available on the market are plastic shopping bags, non-woven shopping bags, paper shopping bags, and cotton and linen shopping bags. In today's society, which pursues a low-carbon and low-pollution lifestyle, the demand for shopping bags is increasing due to the growing population. However, given that they can cause a lot of pollution, environmentally friendly shopping bags are now in use.

[0003] Most existing shopping bags require manual knotting, which is not only cumbersome but also prone to loosening and causing items to fall out. Some shopping bags with zippers require precise alignment to close, making automatic sealing impossible. Furthermore, the handles of most existing shopping bags are of fixed length, meaning they can only be carried by hand or over the shoulder, without the flexibility to adapt to the weight of the items or the carrying scenario, thus reducing carrying comfort and flexibility.

[0004] Therefore, those skilled in the art have provided a shopping bag with an automatic sealing function to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a shopping bag with an automatic sealing function. The automatic shrink sealing eliminates the manual closing step, improving efficiency. The adjustable length of the connecting strap adapts to different carrying habits, enhancing ease of operation. The bag body is composed of various materials, giving the shopping bag multiple functions such as wear resistance, load-bearing capacity, and waterproofing, enabling it to meet diverse usage scenarios.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A shopping bag with an automatic sealing function includes a bag body and two curved straps. A first seal is fixedly provided at the upper part of the bag body near the front end, and a second seal is fixedly provided at the upper part of the bag body near the rear end. Two magnets are fixedly provided at opposite ends inside the first seal and the second seal. Two connecting straps are fixedly provided at the lower ends of the two curved straps. Two first male buckles are fixedly provided at the upper ends of the four connecting straps at opposite ends. Two first female buckles are fixedly provided at the lower ends of the four connecting straps at opposite ends. Two second male buckles are fixedly provided at the upper ends of the four connecting straps at opposite ends. Two second female buckles are fixedly provided at the lower ends of the four connecting straps at opposite ends. The bag body includes a first wear-resistant layer, a reinforcing layer is fixedly disposed inside the first wear-resistant layer, a waterproof layer is fixedly disposed inside the reinforcing layer, and a second wear-resistant layer is fixedly disposed inside the waterproof layer.

[0007] Furthermore, the rear end of the first seal is located at the front end of the second seal, and sealing strips are fixedly provided at the upper end of the first seal and the lower end of the second seal, with the two sealing strips adhering to each other at one end.

[0008] Furthermore, the plurality of first sub-buckles are respectively engaged with the plurality of first female buckles, and the plurality of second sub-buckles are respectively engaged with the plurality of second female buckles.

[0009] Furthermore, the lower ends of the four connecting straps are all fixedly installed at the upper end of the bag body, and two partitions are fixedly installed inside the bag body.

[0012] Furthermore, the thickness of the first wear-resistant layer and the second wear-resistant layer is 0.3 mm, and the thickness of the reinforcing layer is 0.25 mm.

[0013] This utility model has the following beneficial effects: 1. This utility model proposes a shopping bag with an automatic sealing function. When the bag opening is loosened, the first seal and the second seal gradually approach each other. At this time, the magnets attract each other under the action of magnetic force, realizing the automatic closure of the bag opening. When it is necessary to extend the connecting strap, the connection between the first male buckle and the first female buckle, and the connection between the second male buckle and the second female buckle can be released in sequence, so that the connecting strap is in a fully extended state, thereby extending the handle length. When it is necessary to shorten the connecting strap, the connecting strap can be bent so that the first male buckle and the first female buckle are engaged, and then the second male buckle and the second female buckle are engaged, thereby realizing the effective shortening and fixing of the connecting strap. It is not only convenient to carry by hand, but also to carry on the shoulder, improving the flexibility of use.

[0014] 2. The present invention proposes a shopping bag with an automatic sealing function. The first and second abrasion-resistant layers reduce wear on the inside and outside of the bag, and the reinforcing layer enhances the structural strength of the bag. The combined effect of these two layers extends the service life of the shopping bag. The presence of the reinforcing layer allows the shopping bag to carry heavier items, expanding its scope of use and meeting the needs of carrying more or heavier items. The waterproof layer effectively blocks moisture, allowing the shopping bag to be used not only for carrying dry items but also for carrying wet items, thus improving the practicality of the shopping bag.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-5 One embodiment provided by this utility model: A shopping bag with an automatic sealing function includes a bag body 1 and two curved straps 5. A first seal 2 is fixedly provided at the upper end of the bag body 1 near the front end, and a second seal 3 is fixedly provided at the upper end of the bag body 1 near the rear end. Two magnets 10 are fixedly provided at opposite ends of the first seal 2 and the second seal 3. Two connecting straps 4 are fixedly provided at the lower ends of the two curved straps 5. Two first male buckles 6 are fixedly provided at the upper ends of the four connecting straps 4 in pairs, and two first female buckles 7 are fixedly provided at the lower ends of the four connecting straps 4 in pairs, and two second male buckles 8 and two second female buckles 9 are fixedly provided at the lower ends of the four connecting straps 4 in pairs. The rear end of the first seal 2 is set at the front end of the second seal 3. A sealing strip 11 is fixedly set at the upper end of the first seal 2 and the lower end of the second seal 3. The two sealing strips 11 are attached to each other at one end. Multiple first male buckles 6 are respectively engaged with multiple first female buckles 7. Multiple second male buckles 8 are respectively engaged with multiple second female buckles 9. The lower ends of the four connecting straps 4 are fixedly set at the upper end of the bag body 1. Two partitions 12 are fixedly set inside the bag body 1. Specifically, when storing items, simply open the bag opening to place items inside. The two partitions 12 inside the bag body 1 divide the space in an orderly manner, making it easy to classify and store different types of items such as food and daily necessities, avoiding damage caused by mutual squeezing. After the bag opening is loosened, the upper edge of the bag body 1 has an internal elastic fiber strip, such as spandex, which tends to shrink in its natural state. When the bag opening is opened to place items, the elastic fiber strip is stretched and stores force. After being released, the elasticity drives the bag opening to shrink, which in turn causes the first seal 2 and the second seal 3 to gradually approach each other. Finally, they are automatically attracted by the magnets 10 inside the two seals, thus completing the closure. At the same time, the sealing strip 11 is tightly attached under the action of magnetic attraction, forming double protection, which can block air circulation and prevent moisture penetration. The sealing strip 11 is made of food-grade silicone material, which has good elasticity and sealing performance. It can deform under the attraction of the magnets 10 to ensure that there are no gaps at the joint. The automatic shrink sealing design eliminates the manual closing step, making it easy for the elderly and children to use. The two dividers 12 are made of the same polyester fiber material as the reinforcing layer 102 and are fixed inside the bag body 1 by double stitching to ensure that they will not shift due to the squeezing of items when they are sorted and stored. The curved strap 5 is made of TPU elastic material wrapped around a nylon core. Its curvature fits the natural grip angle of the palm and can distribute pressure and reduce the feeling of being squeezed when carrying it. When extending the connecting strap 4, by disengaging the first male buckle 6 from the first female buckle 7 and the second male buckle 8 from the second female buckle 9, the connecting strap 4 can naturally extend to accommodate shoulder carrying needs, especially suitable for distributing shoulder pressure when carrying heavy objects. When shortening the connecting strap 4, by bending the connecting strap 4 to engage the first male buckle 6 with the first female buckle 7, and then bending it a second time to lock the second male buckle 8 with the second female buckle 9, the length can be shortened, making it convenient to carry by hand and suitable for short-distance carrying or quick access to items. This allows the shopping bag to be used as a tote bag or a shoulder bag, adapting to different scenarios and improving its flexibility. The adjustment function of the connecting strap 4 does not require tools and adapts to different carrying habits. The connecting strap 4 is made of nylon braided material, which has bending resistance and fatigue resistance, ensuring long-term stability. The first male buckle 6, the first female buckle 7, and the second male buckle 8 and the second female buckle 9 are all made of ABS plastic, ensuring that the connecting strap 4 will not loosen under load after adjustment.

[0019] Reference Figures 1-6The bag body 1 includes a first wear-resistant layer 101, a reinforcing layer 102 is fixedly disposed inside the first wear-resistant layer 101, a waterproof layer 103 is fixedly disposed inside the reinforcing layer 102, and a second wear-resistant layer 104 is fixedly disposed inside the waterproof layer 103. The first wear-resistant layer 101 and the second wear-resistant layer 104 are both made of nylon, the reinforcing layer 102 is made of polyester fiber, the waterproof layer 103 is made of polyethylene film, the thickness of the waterproof layer 103 is 0.15mm, the thickness of the first wear-resistant layer 101 and the second wear-resistant layer 104 is 0.3mm, and the thickness of the reinforcing layer 102 is 0.25mm. Specifically, the bag body 1 is composed of various materials. The outermost first wear-resistant layer 101 and the innermost second wear-resistant layer 104 are both made of nylon, both with a thickness of 0.3mm. Nylon has high strength and can withstand repeated friction with hard objects such as counters, walls, and packaging, thereby extending the service life of the shopping bag and reducing the cost of repeated purchases. The reinforcing layer 102 is made of polyester fiber with a thickness of 0.25mm. It has high tensile strength and can improve the load-bearing stability of the bag body 1, so that the shopping bag can maintain its structural integrity and is not easily damaged when carrying heavy items. The waterproof layer 103 is made of polyethylene film with a thickness of 0.15mm. It can prevent external rainwater and moisture from entering and prevent internal wet items from leaking out, avoiding pollution to other items or the environment, and improving the practicality and hygiene performance of the bag body 1. The first wear-resistant layer 101 and the reinforcing layer 102 are bonded together with environmentally friendly hot melt adhesive. The reinforcing layer 102 and the waterproof layer 103 are connected by a hot-pressing composite process. The second wear-resistant layer 104 and the waterproof layer 103 are bonded together with environmentally friendly hot melt adhesive. This ensures that the shopping bag does not delaminate when it is under load or bent. The above connection process is a mature and publicly available technology. Therefore, its specific structure and working principle will not be described in detail in this article.

[0020] Working principle: When in use, open the bag opening on the bag body 1, and then place the item inside the bag body 1. After placement, when the bag opening is released, the bag opening has a certain elasticity and will gradually shrink, causing the first seal 2 and the second seal 3 to gradually approach each other, thereby causing the magnet 10 inside the two to automatically attract each other and achieve automatic closure. The sealing strip 11 is tightly attached under the action of magnetic attraction. When it is necessary to extend the connecting strap 4, the connection between the first male buckle 6 and the first female buckle 7 is released, and then the connection between the second female buckle 9 and the second male buckle 8 is released, so that the connecting strap 4 can be extended. When it is necessary to shorten the connecting strap 4, the first male buckle 6 and the first female buckle 7 are engaged by bending the connecting strap 4, and then the second female buckle 9 and the second male buckle 8 are engaged by bending the connecting strap 4, so that the connecting strap 4 can be shortened, thus improving the flexibility of use. The first wear-resistant layer 101 and the second wear-resistant layer 104 are both made of nylon, with a thickness of 0.3mm. Nylon has high wear resistance and can effectively resist friction between the shopping bag and external objects and internal items during use, thereby extending the service life of the shopping bag. The reinforcing layer 102 is made of polyester fiber, with a thickness of 0.25mm. Polyester fiber has strong tensile strength and structural stability, which can enhance the overall load-bearing capacity of the bag body 1, making the shopping bag less prone to damage when carrying heavy items. The waterproof layer 103 is made of polyethylene film, with a thickness of 0.15mm. Polyethylene film has good waterproof performance, which can effectively prevent water penetration and prevent the items inside the bag from getting wet. It can also prevent moisture from the damp items inside the bag from seeping out and contaminating other items or the environment.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
