[0017] refer to Figures 1 to 5 The nozzle shown can be used as a flow guide cup on a plastic packaging bag, including a square bottom base 1 fixed on the packaging bag by heat sealing technology, a base flow guide port 5 is provided on the square bottom base 1, and the content flows out through the base flow guide port 5, and the upper end of the base flow guide port 5 is arranged in an arc shape, and a top cover 2 is detachably provided on the square bottom base 1, and the top cover 2 is fixed to the square bottom base 1 by threads, and the top cover 2 is used to contain the content.

[0018] The square bottom base 1 is installed on the packaging bag. The square bottom base 1 is installed on the square bottom base 1 by heat sealing technology. The square setting of the square bottom base 1 improves the positioning effect of the square bottom base 1 during installation. The four edges of the square bottom base 1 form right angles, which makes it easier to position during installation. The edges can be aligned with the edges or marking lines of the packaging bag to ensure the accurate installation position of the square bottom base 1. At the same time, the square bottom base 1 has a larger contact area relative to the edge or marking line of the packaging bag, providing a more stable support to prevent the square bottom base 1 from being displaced during use. The square bottom base 1 is provided with a base heat sealing ring 4, which makes better contact and adhesion with the material of the packaging bag during the heat sealing process, thereby improving the sealing performance between the square bottom base 1 and the packaging bag, effectively preventing liquid or gas from leaking through the seam between the square bottom base 1 and the packaging bag, and improving the sealing and freshness preservation of the packaging. At the same time, the base heat sealing ring 4 improves the stability of the entire structure, and the base heat sealing ring 4 reduces the displacement or loosening of the square bottom base 1 during use, ensuring the stable installation of the nozzle or other components. The square bottom base 1 A base guide port 5 is also provided inside, and the objects in the packaging bag flow out through the base guide port 5. The upper end of the base guide port 5 is set to be arc-shaped, and the contents flow out through the highest end of the arc on the base guide port 5. The design of the base guide port 5 can reduce the possibility of liquid dripping and splashing. At the same time, the arc shape of the base guide port 5 prompts the liquid to flow out in a smoother manner, reduces the instability of the liquid during the outflow process, and reduces the risk of dripping and splashing. The arc design of the base guide port 5 can quickly change the outflow direction of the liquid, and it is guided to a certain extent at the arc edge of the base guide port 5, making the outflow direction more accurate. The invention is accurate and controllable. According to the different contents and the needs when the contents flow out, base guide ports 5 of different specifications are installed inside the square bottom base 1 to control the speed and flow rate of the contents flowing out. The larger cylindrical arc size can provide a larger flow area, so that the liquid flows out at a faster speed; while the smaller cylindrical arc size can slow down the flow rate and realize a more delicate contents flow out. The arc design of the base guide port 5 reduces the reflux speed when the contents flow back, reduces the impact force of the contents flowing back, and makes the contents reflux more gentle and controllable. A gap is set between the base guide port 5 and the square bottom base 1.

[0019] A top cover 2 is provided on the square bottom base 1, and the top cover 2 is connected to the square bottom base 1 through threads. After the top cover 2 is tightened on the square bottom base 1, the square bottom base 1 and the packaging bag are sealed to prevent liquid from flowing out. A pressing cover 7 is provided inside the top cover 2. When the top cover 2 is tightened on the square bottom base 1, the pressing cover 7 is inserted into the gap between the square bottom base 1 and the base flow guide port 5, and the pressing cover 7 blocks the gap to enhance the sealing performance. When the top cover 2 is tightened, a sealing isolation layer is formed between the pressing cover 7 and the gap, which prevents the entry of external substances or the leakage of internal substances, maintains the sealing of the system, prevents the leakage or contamination of liquid, gas or other substances, and prevents the annular gap between the square bottom base 1 and the base flow guide port 5 from being occupied by irrelevant substances, such as dust, foreign matter, etc., to ensure Maintain the cleanliness and reliability of the system and reduce the impact of external factors on the sealing performance. When the contents reflux, the design of the pressing cover 7 and the annular gap can control the speed of liquid reflux. The pressing cover 7 will form an obstacle to hinder the flow of liquid, slow down the reflux speed, and prevent the liquid from refluxing too fast and causing overflow or uncontrolled situations. The top cover 2 is provided with multiple groups of anti-slip threads 3 on the outside. The anti-slip threads 3 provide a better feel and grip, so that the operator is more stable and safe when tightening or loosening the top cover. The texture design of the anti-slip threads 3 can increase friction, reduce the possibility of hand slippage, reduce the risk of accidental slippage or misoperation, provide better friction, and the anti-slip threads 3 ensure the tightness of the top cover, reduce the risk of liquid leakage or external substances entering due to loosening of the top cover, and improve the sealing and protection performance.

[0020] A plurality of groups of scale lines 6 are arranged inside the push cover 7, and the scale lines 6 are used to measure or estimate the capacity of the contents. By reading the scale, the user can understand the volume or weight of the liquid or substance in the top cover 2, which is very useful in applications that require accurate control or recording of the quantity or volume of the contents, such as laboratory operations, food preparation or liquid formulation, etc. At the same time, the scale helps the user to accurately dilute or adjust the concentration of the liquid in the container. By reading the scale, the user can understand the exact amount of solvent or solute that needs to be added to achieve the desired concentration, which is very useful in chemical experiments, preparation of medical supplies or industrial production.

[0021] Working principle: during operation, the square bottom base 1 and the base heat-sealing ring 4 are fixed to the packaging bag by heat sealing, and the top cover 2 is tightened on the square bottom base 1 by threads. At this time, the pressing cover 7 blocks the gap between the square bottom base 1 and the base guide port 5 to prevent leakage of the contents. When the liquid in the bag needs to be poured out, unscrew the top cover 2, align the highest point of the arc position of the upper end of the base guide port 5 with the top cover 2, and then tilt the packaging bag. At this time, the contents enter the top cover 2 through the base guide port 5. By observing the scale line 6 on the pressing cover 7, the volume of the liquid in the top cover 2 is judged to avoid pouring too much or too little content, improve the use effect, and straighten the packaging bag. At this time, the liquid in the packaging bag refluxes through the base guide port 5. The set base guide port 5 prevents the refluxed liquid from leaking, and then the top cover 2 is tightened on the square bottom base 1 to complete the extraction of the contents.

[0022] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative labor all fall within the protection scope of the present invention.
