By setting a self-sealing strip, it can be sealed after putting objects in, effectively avoiding the entry of hot air or the dissipation of internal hot air, improving the sealing effect of the handbag, and further enhancing the heat preservation performance, with high practicability.

[0015] 2. Through the design of the connecting strip and the stopper in the present utility model, when the handle lifts the bag body, the connecting strip pulls the stopper upward, and the stopper squeezes the elastic piece, thereby using the deformation of the elastic piece to provide a buffering effect, effectively reducing the shaking of the items inside the bag body, preventing the items from being overturned or leaking out due to excessive shaking inside the bag body, and adding a buffering mechanism between the handle and the bag body, enhancing the overall stability of the handbag. Even during large-amplitude shaking during lifting and carrying, the relative stability of the internal items can still be maintained, reducing the risk of item dumping. And the addition of the buffering structure effectively reduces the impact force caused by item shaking, avoids damage caused by the mutual collision of items inside the bag, and improves the safety during the use of the handbag. In summary, the present utility model improves the practicability and convenience of the handbag during use, enabling users not to worry too much about the shaking and leakage of internal items during carrying and handling, and providing a better user experience.

[0027] Please refer to Figures 1-7 , the present utility model provides a technical solution: a highly reflective composite heat-insulating and heat-preserving handbag, including a bag body 1, an opening 2 is provided on the top surface of the bag body 1, and a self-sealing strip 3 is fixedly installed inside the opening 2. The self-sealing strip 3 can be fixed inside the opening 2 by means of hot melt adhesive bonding or ultrasonic welding to ensure the sealing effect. A reinforcing cardboard sheet 4 is fixedly installed on the surface of the bag body 1, and a connecting strip 5 penetrates through the top surface of the reinforcing cardboard sheet 4. The connecting strip 5 can be installed on the top surface of the reinforcing cardboard sheet 4 by means of riveting or bolt fixing to enhance the connection strength. A handle 6 is fixedly installed at the top end of the connecting strip 5. The handle 6 is made of PP plastic. The PP plastic material is firm and durable and can bear the pulling force when pulled. The handle is a tubular structure, and the two ends of the handle are provided with rounded corners for convenient taking. In addition, PVC and nylon materials can also be used. The PVC material has good flexibility, while the nylon material has high strength and wear resistance.

[0028] Please refer to Figures 1-7, the bag body 1 includes a PE layer 101, and an aluminized film 102 and an EPE foam 103 are fixedly installed on the surface of the PE layer 101. The aluminized film 102 can be fixed on the surface of the PE layer 101 by coating or lamination processes, while the EPE foam 103 is fixed on the other side of the PE layer 101 by hot pressing or glue bonding. A buffer mechanism is provided inside the reinforcing cardboard sheet 4. The buffer mechanism includes an inner cavity 7, which is opened inside the reinforcing cardboard sheet 4. The connecting strip 5 is slidably connected to the reinforcing cardboard sheet 4, and a stopper 8 is fixedly installed at the bottom end of the connecting strip 5. The stopper 8 can be fixed to the bottom end of the connecting strip 5 by threaded connection or snap-fastening. A spring plate 9 is fixedly installed on the top surface of the stopper 8, and the spring plates 9 are symmetrically distributed on the top surface of the stopper 8. The spring plates 9 can be made of spring steel or shape memory alloy materials, with good elasticity and not easily deformed.

[0029] Embodiment Two

[0030] Please refer to Figures 2-3 , support columns 10 are fixedly installed on the bottom surface of the bag body 1. The support columns 10 are evenly distributed on the bottom surface of the bag body 1, and the material of the support columns 10 is natural rubber. When the bag body 1 is placed on the ground, the provided support columns 10 can support the bag body 1 off the ground, which can prevent the bottom surface of the bag body 1 from being worn, thereby increasing the service life of the bag body 1; bending marks are provided on both sides of the bag body, which is convenient for folding and storage. The support columns 10 can be fixed to the bottom surface of the bag body 1 by bolts or riveting. Such a connection method is not only firm but also convenient for replacement, further extending the service life of the bag body 1.

[0031] Working principle: The bag body 1 has three layers, namely a PE layer 101, an aluminized film 102, and an EPE 103. The aluminized film 102 faces inward and the EPE 103 faces outward. In this way, the heat reflection characteristics of the aluminized film 102 can effectively improve the heat preservation effect. At the same time, the set PE layer 101 can be fully degraded, which is beneficial to environmental protection. And through the set self-sealing strip 3, after putting an object through the opening 2, it can be sealed through the self-sealing strip 3, which can improve the sealing effect, avoid hot air from entering, and through the set handle 6, it can also be conveniently carried. The utility model adopts a three-layer structure of an aluminized film 102, an EPE 103, and a PE layer 101. Among them, the aluminized film 102 faces inward. By using its heat reflection characteristics, the heat preservation performance of the handbag is effectively improved, heat loss is reduced, and the temperature inside the bag is kept stable. And by using the PE layer 101 material, it has sufficient degradability, reduces the impact on the environment, and improves the environmental friendliness of the product. By setting the self-sealing strip 3, it can be sealed after putting an object, effectively avoiding the entry of hot air or the loss of internal hot air, improving the sealing effect of the handbag, and further enhancing the heat preservation performance. When lifting the bag body 1 by the handle 6, if there is a large swing, the connecting strip 5 can pull up the stopper 8. At this time, the stopper 8 can squeeze the elastic piece 9. At this time, the deformation of the elastic piece 9 can play a buffering effect, which can avoid excessive shaking of the items in the bag body 1 and prevent them from being overturned or leaking out, improving the practicability. Through the design of the connecting strip 5 and the stopper 8 of the utility model, when the handle 6 lifts the bag body 1, the connecting strip 5 pulls up the stopper 8, and the stopper 8 squeezes the elastic piece 9, thereby using the deformation of the elastic piece 9 to provide a buffering effect, effectively reducing the shaking of the items inside the bag body 1, preventing the items from being overturned or leaking out due to excessive shaking in the bag body 1, and adding a buffering mechanism between the handle 6 and the bag body 1, enhancing the overall stability of the handbag. Even when there is a large swing during the lifting and carrying process, it can still keep the relative stability of the internal items, reducing the risk of item dumping. And the addition of the buffering structure effectively reduces the impact force caused by item shaking, avoiding damage caused by the mutual collision of items in the bag, and improving the safety during the use of the handbag. In summary, the utility model improves the practicability and convenience of the handbag in use, enabling users not to worry too much about the shaking and leakage of internal items during the carrying and handling process, and providing a better user experience.

[0032] Of course, the present utility model may have many other implementation manners. Based on this implementation manner, other implementation manners obtained by ordinary technical personnel in the field without any creative labor belong to the scope protected by the present utility model.
