AI Technical Summary
Existing liquid stand-up pouches are not easy to hold when pouring soup, and they are prone to deformation and spillage when the soup volume decreases, making them inconvenient to use.
A liquid packaging stand-up pouch has been designed, comprising an outer bag and an inner bag. The top and one side of the outer bag are connected to an extension edge, and it is equipped with a handle and a liquid outlet. It is also equipped with a spout, an extension strap, and a pull ring. It is combined with a column to maintain its shape stability. The spout can be tilted by adjusting its direction and angle with your fingers.
It enables control of the pouring direction of the soup without direct contact with the bag, preventing spills and maintaining the bag's shape, providing a convenient pouring experience.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of stand-up pouch technology, and in particular to a liquid packaging stand-up pouch. Background Technology
[0002] A stand-up pouch is a flexible packaging bag with a horizontal support structure at the bottom, which can stand upright without relying on any support and regardless of whether the bag is opened or not.
[0003] With the improvement of living standards, in the food delivery industry, to ensure that the soup in dishes such as noodles purchased by buyers does not spill during transportation and to maintain the freshness of the food, liquid packaging bags are used to store the soup separately for easy delivery. However, when buyers need to pour the soup back into the bowl containing the food, the heat of the soup is transferred to the stand-up pouch, causing it to become too hot to hold. Existing stand-up pouches do not have any gripping components, and as the liquid gradually decreases during the pouring process, the shape of the stand-up pouch may suddenly deform, changing the angle and direction of the pour, causing the soup to spill. Buyers cannot immediately eat the food they purchased, and they need to handle the pouring process with great care, which is quite inconvenient.
[0004] Therefore, it is necessary to invent a liquid packaging stand-up pouch to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a liquid packaging stand-up pouch to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquid packaging stand-up pouch, comprising a main bag, the main bag being composed of an outer bag and an inner bag, the inner bag being composed of a leak-proof layer and an insulation layer, the top of the outer bag being connected to a first extending edge, one side of the outer bag being connected to a second extending edge, both the first and second extending edges being provided with handles, one side of the outer bag being provided with a liquid outlet, the liquid outlet being connected to a suction nozzle, one side of the suction nozzle being connected to an extension strap, one side of the extension strap being connected to a pull ring, and one side of the main bag being connected to a column.
[0007] Preferably, the leak-proof layer is made of polyethylene.
[0008] Preferably, the insulation layer is made of polypropylene.
[0009] Preferably, the specific material of the column is hard rubber.
[0010] The technical effects and advantages of this utility model are as follows: By using a first extended edge, a second extended edge, an extended strap, a pull ring, and a column in combination, when pouring soup, both hands hold the handles of the first and second extended edges respectively, and one finger hooks the pull ring to adjust the direction and angle of the spout. The column can maintain the shape of the stand-up pouch when pouring, which allows the soup to be poured out of the stand-up pouch without direct contact with it. By controlling the direction and angle of the spout, the soup will not spill, and the stand-up pouch will not deform as the soup gradually decreases, providing convenience for the buyer. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the overall structure of this utility model;
[0012] Figure 2 This is a schematic diagram of the inner bag structure of this utility model.
[0013] In the diagram: 1. Main bag; 2. Outer bag; 3. Inner bag; 4. Leak-proof layer; 5. Insulation layer; 6. First extension edge; 7. Second extension edge; 8. Handle; 9. Nozzle; 10. Extension strap; 11. Pull ring; 12. Column. Detailed Implementation
[0014] 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.
[0015] This utility model provides, for example Figure 1-2 The liquid packaging stand-up pouch shown includes a main bag 1, which is composed of an outer bag 2 and an inner bag 3. The inner bag 3 is composed of a leak-proof layer 4 and an insulation layer 5. The top of the outer bag 2 is connected to a first extension edge 6, and one side of the outer bag 2 is connected to a second extension edge 7. Both the first extension edge 6 and the second extension edge 7 are provided with handles 8. One side of the outer bag 2 is provided with a liquid outlet, and a suction nozzle 9 is connected to the liquid outlet. One side of the suction nozzle 9 is connected to an extension strap 10, and one side of the extension strap 10 is connected to a pull ring 11. One side of the main bag 1 is connected to a column 12.
[0016] The leak-proof layer 4 is made of polyethylene to ensure that the soup will not leak.
[0017] The insulation layer 5 is made of polypropylene to ensure that the temperature of the soup does not drop too much during transportation.
[0018] The column 12 is made of hard rubber to ensure the stability of the self-standing bag's shape during the pouring process.
[0019] The working principle of this utility model is as follows: When pouring soup, both hands hold the handles 8 of the first extension edge 6 and the second extension edge 7 respectively, and one finger hooks the pull ring 11 to adjust the direction and angle of the suction nozzle 9. The column 12 can maintain the shape of the self-standing bag when pouring. The polyethylene as the leak-proof layer 4 can ensure that the soup will not leak out, and the polypropylene as the heat insulation layer 5 can ensure that the heat of the soup will not be lost too much during transportation, which provides convenience for buyers to pour soup.
[0020] 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.
