Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Refer to the instruction manual Figure 1-5The utility model provides a food packaging bag, including a bag body 1 for packaging food, wherein the outer walls of the front and rear sides of the bag body 1 are fixedly provided with bracket assemblies 2, and the two bracket assemblies 2 each include three support rods 201, and the plurality of support rods 201 are respectively fixed on the front and rear outer walls of the bag body 1, and the three support rods 201 on the front and rear outer walls of the bag body 1 correspond to each other one by one, and two connecting rods 202 that are movably connected front and back are arranged between two adjacent support rods 201, and specifically, the two connecting rods 202 distributed front and back are connected by a pin shaft 8, so as to facilitate the adjustment of the positions of the two support rods 201, and sliders 203 are movably arranged at both ends of each connecting rod 202, and a slide groove 204 that is adapted to the slide groove 203 is opened on the outer wall of each support rod 201, and the number of the slide grooves 204 on the two support rods 201 located in the middle of the bag body 1 is two;

[0025] Multiple sliders 203 are respectively arranged in multiple slide grooves 204, and are used to connect the connecting rod 202 and the support rod 201 together, wherein a long board 3 is connected between two front-to-back symmetrical support rods 201, and snap male heads 6 are fixedly provided on the outer walls of the two long boards 3, and snap female heads 7 adapted to the snap male heads 6 are fixedly embedded on the two front-to-back symmetrical support rods 201, and each snap male head 6 is respectively buckled in each snap female head 7, and the two front-to-back corresponding support rods 201 are connected together by the long board 3, so as to improve the stability of the two bracket assemblies 2.

[0026] When placing the bag body 1, the user can pull the support rod 201 to separate the three support rods 201 from each other. During the movement of the support rod 201, the two movably connected connecting rods 202 are driven to open. The connecting rod 202 and the support rod 201 are combined to form a scissor-type bracket assembly 2, which plays a supporting and reinforcing role on the front and back sides of the bag body 1. At the same time, two long plates 3 are used to connect the two groups of support rods 201 symmetrically front and back together, so as to further improve the stability of the scissor-type bracket assembly 2. The scissor-type bracket assembly 2 can be used to place the bag body 1 vertically and to reinforce the outside of the bag body 1, so as to improve the use strength and service life of the bag body 1. After pushing the three support rods 201 together, the occupied area of ​​the bag body 1 can be reduced, so as to facilitate carrying the bag body 1.

[0027] Refer to the instruction manual Figure 1-5 The bag body 1 is made of polypropylene material to improve the use strength of the bag body 1. A discharge pipe 4 is fixedly penetrated at the top edge of the bag body 1. A threaded cover 5 is threadedly connected to the outer wall of the discharge pipe 4. A guide pipe 9 is fixedly arranged inside the discharge pipe 4. An opening 10 is opened between the guide pipe 9 and the discharge pipe 4. The opening 10, the guide pipe 9 and the discharge pipe 4 are all connected to the inside of the bag body 1. The liquid food is guided to flow out by the guide pipe 9, so as to reduce the waste of liquid food.

[0028] In addition, a spring latch 11 is fixedly passed through the threaded cover 5, and a slot 12 adapted to the spring latch 11 is formed on the outer wall of the discharge pipe 4. The spring latch 11 is inserted in the slot 12 to improve the firmness between the threaded cover 5 and the discharge pipe 4 and prevent the threaded cover 5 from loosening and affecting the sealing of the bag body 1. The threaded cover 5 is arranged between two front-to-back symmetrical support rods 201 to prevent the support rods 201 from hindering the use of the threaded cover 5.

[0029] When it is necessary to pour out the liquid food in the bag body 1, the user first pulls out the spring latch 11 from the slot 12, then unscrews the threaded cover 5, holds the multiple support rods 201 to invert the bag body 1, so that the liquid food in the bag body 1 flows out from the guide tube 9 in the discharge tube 4. After pouring out the liquid food, the user can put the bag body 1 upright, so that the liquid food adhered to the guide tube 9 automatically flows into the discharge tube 4, and then flows into the bag body 1 from the opening 10. After pouring out the liquid food each time, the user does not need to manually wipe off the liquid food, thereby reducing the waste of liquid food.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
