Specific implementation manners
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: a PVC bag with heat preservation, waterproof and portability, including a PVC bag body 1; in order to prevent the stored food from deteriorating due to temperature influence, an airtight zipper 12 of the main PVC bag is installed on the PVC bag body 1, side storage bags 2 are installed on both sides of the PVC bag body 1, and a secondary storage bag 8 is installed on one side of the PVC bag body 1. It is sealed and waterproof through the airtight zipper 12 of the main PVC bag, and the side storage bag 2 and the secondary storage bag 8 are used for auxiliary storage;
[0024] In order to achieve the functions of heat preservation and waterproofing, a main zipper groove 22 is opened on the upper surface of the PVC bag main body 1. The main PVC bag airtight zipper 12 is installed in the main zipper groove 22, and a main PCV zipper lock 13 is installed on the main PVC bag airtight zipper 12. On one side surface of the secondary storage bag 8, a secondary zipper groove 23 is opened. The secondary storage bag airtight zipper 10 is installed in the secondary zipper groove 23, and a secondary storage bag zipper lock 11 is installed on the secondary storage bag airtight zipper 10. The secondary storage bag zipper lock 11 meshes with the secondary storage bag airtight zipper 10, and the main PCV zipper lock 13 meshes with the main PVC bag airtight zipper 12. A side storage cavity 3 is opened inside the side storage bag 2. A side storage bag tightening rope 4 is installed above the side storage bag 2, and a buckle connection rope 7 is installed above the side storage bag 2. A tightening rope buckle 5 is installed on the buckle connection rope 7, and a buckle groove 6 is opened on the tightening rope buckle 5. The side storage bag tightening rope 4 passes through the buckle groove 6 and is installed on the tightening rope buckle 5. A buffer groove 14 is opened below the PVC bag main body 1, and buffer cotton 15 is installed in the buffer groove 14. A secondary storage cavity 9 is opened inside the secondary storage bag 8, and a main storage cavity 18 is opened inside the PVC bag main body 1. An elastic stretchable band 19 and a magic tape 20 are both installed in the main storage cavity 18. Heat preservation materials are installed on the inner walls of the secondary storage cavity 9 and the main storage cavity 18. The heat preservation material is made of aluminum foil or tin foil. When placing items, pull the main PCV zipper lock 13 on the PVC bag main body 1 to make the main PCV zipper lock 13 move to the other side, and then the main PVC bag airtight zippers 12 on both sides can be separated by using the main PCV zipper lock 13. At this time, the main storage cavity 18 can be opened, and the items to be stored can be placed in the main storage cavity 18. After the storage is completed, reset the secondary storage bag zipper lock 11, and the secondary storage bag airtight zippers 10 on both sides can be meshed again. When storing items such as lunch boxes, the elastic stretchable band 19 can be passed over the lunch box, and one end of the elastic stretchable band 19 can be pasted on the magic tape 20 to limit the items below the elastic stretchable band 19 and prevent the lunch box from flipping when carried out. The elastic stretchable band 19 has elasticity and can be stretched according to the height of the items stored below. The secondary storage bag 8 on the side of the PVC bag main body 1 can also be used for storage. Heat preservation materials are installed on the inner walls of the PVC bag main body 1 and the secondary storage bag 8, which can slow down the internal temperature loss and, to a certain extent, isolate the external temperature, avoiding the influence of excessive internal and external temperature differences on the internal items. Buffer cotton 15 is arranged below the PVC bag main body 1. When the PVC bag main body 1 accidentally falls or is placed too forcefully, the buffer cotton 15 can play a certain buffering role for the internal items. The side storage bag 2 on the side of the PVC bag main body 1 can store items such as water cups or umbrellas, and the tightening rope buckle 5 and the side storage bag tightening rope 4 can be used to fix it to prevent it from shaking in the side storage cavity 3.
[0025] The working principle is as follows: When placing an item, pull the main PVC zipper lock 13 on the PVC bag body 1, so that the main PVC zipper lock 13 moves to the other side, and the main PVC bag airtight zippers 12 on both sides can be separated by using the main PVC zipper lock 13. At this time, the main storage cavity 18 can be opened, and the items to be stored can be placed in the main storage cavity 18. After the storage is completed, reset the secondary storage bag zipper lock 11, and the secondary storage bag airtight zippers 10 on both sides can be engaged again. When storing items such as lunch boxes, the elastic stretch belt 19 can be passed over the lunch box, and one end of the elastic stretch belt 19 can be pasted on the magic tape 20 to limit the items below the elastic stretch belt 19 and prevent the lunch box from flipping when carried out. The elastic stretch belt 19 is elastic and can be stretched according to the height of the items stored below. The secondary storage bag 8 on the side of the PVC bag body 1 can also be used for storage. Heat preservation materials are installed on the inner walls of the PVC bag body 1 and the secondary storage bag 8, which can slow down the internal temperature loss and can also isolate the external temperature to a certain extent, avoiding the influence of excessive internal and external temperature differences on the internal items. A buffer cotton 15 is arranged below the PVC bag body 1. When the PVC bag body 1 accidentally falls or is placed too forcefully, the buffer cotton 15 can play a certain buffering role for the internal items. The side storage bag 2 on the side of the PVC bag body 1 can store items such as water cups or umbrellas, and the tightening rope buckle 5 and the side storage bag tightening rope 4 can be used to fix it to prevent it from shaking in the side storage cavity 3. The bag handle 21 provided above the PVC bag body 1 can facilitate people to hold the PVC bag body 1 when going out. When multiple people around use the same product, personal information or business cards can be stuffed into the business card holder bag 16, which is convenient for quickly identifying one's own bag among multiple products with the same appearance.
[0026] Embodiment 2: As Figures 1-5 , for the convenience of holding and quickly identifying one's own bag, a bag handle 21 is installed on the PVC bag body 1, a business card holder bag 16 is installed on one side of the PVC bag body 1, and a business card holder buckle 17 is installed on the business card holder bag 16. The bag handle 21 provided above the PVC bag body 1 can facilitate people to hold the PVC bag body 1 when going out. When multiple people around use the same product, personal information or business cards can be stuffed into the business card holder bag 16, which is convenient for quickly identifying one's own bag among multiple products with the same appearance. The other features are the same as those in Embodiment 1.
[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
