Description

Technical Field

[0001] This utility model relates to the field of stand-up pouch technology, and in particular to a portable stand-up pouch with an automatic valve. Background Technology

[0002] A portable stand-up pouch with an automatic valve is a type of packaging bag that can stand upright on its own, is easy to carry, and has a valve that can be opened and closed. The valve controls the flow of substances in or out of the bag and is often used to hold liquids, semi-fluids, and other similar items.

[0003] When liquid is discharged from the stand-up pouch through the valve, the pressure inside the stand-up pouch gradually decreases, while the external pressure flattens the stand-up pouch. After the liquid has been discharged through the valve for a period of time, the stand-up pouch needs to be inverted and the valve opened to allow outside air to enter the stand-up pouch and balance the internal and external pressures. This operation is cumbersome. Therefore, this application provides a portable stand-up pouch with an automatic valve to meet the requirements. Utility Model Content

[0004] This invention provides a portable self-standing bag with an automatic valve to solve the problem of poor material discharge.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A portable stand-up pouch with an automatic valve includes a pouch body, a valve connected to the surface of the pouch body, the valve being located near the bottom of the pouch body, and further includes: A breathable component, comprising a breathable tube fixedly extending through the surface of the bag, the surface of the breathable tube having a through hole, and a plug being movably inserted into the breathable tube; When the liquid inside the bag is drained through the valve, the plug is pulled out, and air enters the bag through the vent tube and the through hole.

[0006] Preferably, the end of the plug is provided with an arc-shaped chamfer.

[0007] Preferably, a protective film is fixed to the end of the plug away from the bag body, and the edge of the protective film is fixed to the surface of the bag body.

[0008] Preferably, the protective film has a tear opening located between the vent tube and the connection between the protective film and the bag body.

[0009] Preferably, a pull strap is fixed to the surface of the protective film.

[0010] Preferably, the pull strap has a protrusion fixed on the side near the protective film, and the surface of the protrusion is provided with anti-slip stripes.

[0011] Preferably, the ventilation tube has a sloping surface on the side near the inner wall of the bag, and the sloping surface is adapted to the inclination direction of the inner wall of the bag.

[0012] Preferably, a filter screen is fixed to the vent pipe at the through hole.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting up a vent pipe, a through hole, and a plug, when liquid needs to be discharged from the valve, the plug is pulled out from the vent pipe. When the liquid flows out of the valve, outside air can enter the bag through the vent pipe and the through hole, balancing the pressure inside the bag, thereby allowing the liquid to be discharged smoothly from the valve, making the operation more convenient.

[0014] By setting a protective membrane, the bag can be stably fixed inside the vent tube during transportation, preventing the bags from squeezing each other and increasing the internal pressure, which would cause the plug to be squeezed out of the vent tube, making the bag more stable during transportation.

[0015] By incorporating a tear vent, the protective membrane can be easily ruptured when the plug needs to be removed. Once the bottom of the protective membrane is ruptured, it acts as a handle, making it easier to pull the plug out of the vent tube, thus making the operation more convenient.

[0016] By incorporating a pull strap and raised sections, when pulling the protective film, the user can pinch the raised section of the pull strap to increase friction between the hand and fingers, making it easier to tear the protective film and simplifying the operation.

[0017] By setting up a sloping surface, the sloping surface can fit inside the bag body to avoid damage to the bag body. Secondly, the vent tube can open the cavity in the upper half of the inner wall of the bag, making it easier for air to enter the bag body and further improving the smoothness of liquid discharge.

However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0021] The present invention provides a portable self-standing bag with an automatic valve, which will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0022] like Figures 1-3 As shown, an embodiment of this utility model provides a portable stand-up pouch with an automatic valve, including a pouch body 1, a valve 2 connected to the surface of the pouch body 1, the valve 2 being located near the bottom of the pouch body 1, and further including: The breathable component 3 includes a breathable tube 4 that is fixedly inserted through the surface of the bag body 1. The surface of the breathable tube 4 is provided with a through hole 5, and a plug 8 is movably inserted into the breathable tube 4. When the liquid in the bag body 1 is discharged through valve 2, the plug 8 is pulled out, and air enters the bag body 1 through the vent pipe 4 and the through hole 5. The bag body 1 is used to store liquid. The valve 2 is close to the bottom to facilitate the complete discharge of liquid. The vent pipe 4 and the through hole 5 form a venting channel. When the plug 8 is pulled out, outside air can enter the bag body 1 through this channel to balance the negative pressure formed in the bag due to the discharge of liquid, prevent the bag body 1 from collapsing and blocking the valve 2, and ensure that the liquid can flow out smoothly. This solves the problem of slow flow rate or interruption caused by air pressure imbalance when the liquid is discharged from the traditional self-standing bag, and improves the convenience of use. When the liquid is not being discharged, the plug 8 seals the vent pipe 4 to prevent the liquid in the bag from leaking out or the entry of external impurities, and ensures the airtightness of the bag body 1.

[0023] like Figure 2 As shown in this embodiment, the end of the stopper 8 is provided with an arc-shaped chamfer. The arc-shaped chamfer removes the sharp edges of the end of the stopper 8, making it easier to insert or pull out the vent tube 4. This avoids scratching the inner wall of the vent tube 4 or the surface of the bag body 1 due to the sharp end, thus extending the service life of the component. At the same time, the chamfer design makes it easier for the stopper 8 to be inserted into the vent tube 4, making lifting more convenient.

[0024] like Figure 2 and Figure 3As shown in this embodiment, a protective film 9 is fixed to the end of the stopper 8 away from the bag body 1. The edge of the protective film 9 is fixed to the surface of the bag body 1. The protective film 9 connects the stopper 8 to the bag body 1, and can firmly fix the stopper 8 during transportation and storage, preventing the stopper 8 from accidentally falling off due to the squeezing and vibration of the bag body 1, avoiding the leakage of liquid or the entry of impurities caused by the opening of the vent tube 4, enhancing the sealing performance and transportation stability of the bag body 1. In addition, the protective film 9 can also protect the interface between the stopper 8 and the vent tube 4 from contamination.

[0025] like Figure 3 As shown in this embodiment, a tear 10 is provided on the protective film 9. The tear 10 is located between the ventilation tube 4 and the connection between the protective film 9 and the bag body 1. The tear 10 provides a preset tear point for the protective film 9, so that the user can easily tear the protective film 9 without the aid of tools. The operation is labor-saving and convenient. Its position design ensures that the protective film 9 can still partially connect to the plug 8 after tearing. It can be used as a handle to remove the plug 8, avoiding the possible contamination caused by direct contact with the plug 8, and preventing the plug 8 from falling off and being lost.

[0026] like Figure 3 As shown in this embodiment, a pull strap 11 is fixed to the surface of the protective film 9. The pull strap 11 provides a clear point of force for tearing the protective film 9. Users can easily tear the protective film 9 by pulling the pull strap 11. Especially when the protective film 9 is made of a tough material, it can significantly reduce the difficulty of tearing, improve the convenience and efficiency of operation, and avoid affecting the user experience due to difficulty in tearing.

[0027] like Figure 3 As shown in this embodiment, a protrusion 12 is fixed on the side of the pull strap 11 near the protective film 9. The surface of the protrusion 12 is provided with anti-slip stripes. The protrusion 12 increases the contact area between the fingers and the pull strap 11. Combined with the anti-slip stripes, it can significantly increase the friction force, prevent the fingers from slipping when pulling the pull strap 11, and ensure effective force application. Especially when the hands are wet or oily, it can still be operated stably, further improving the convenience and reliability of use.

[0028] like Figure 2 As shown in this embodiment, the vent tube 4 is provided with a slope 6 on the side near the inner wall of the bag body 1. The slope 6 is adapted to the inclination direction of the inner wall of the bag body 1. The slope 6 makes the end of the vent tube 4 fit tightly against the inner wall of the bag body 1, avoiding the tip of the vent tube 4 from piercing the bag body 1 or causing local wear, thus protecting the structural integrity of the bag body 1. At the same time, the fitting design can guide air to enter the upper cavity of the bag body 1 more smoothly, reduce airflow resistance, ensure timely air supply during liquid drainage, and further improve the smoothness of liquid drainage.

[0029] like Figure 2As shown in this embodiment, a filter screen 7 is fixed at the through hole 5 and the vent pipe 4. The filter screen 7 can effectively block external dust and impurities from entering the bag body 1 through the through hole 5 and the vent pipe 4, thus avoiding contamination of the liquid inside the bag. It is especially suitable for storing liquids with high hygiene requirements, such as food and beverages. At the same time, the filter screen 7 does not affect air circulation, thus improving the hygiene and safety of the bag body 1 while ensuring the ventilation function.

[0030] Working principle: When using, pinch the protrusion 12 of the pull strap 11 with your fingers and pull the pull strap 11 outward to tear the protective film 9 from the tear 10. Then continue to hold the protective film 9 or directly grab the stopper 8 and pull the stopper 8 out of the vent tube 4. Next, open the valve 2. The liquid in the bag flows out from the valve 2 under the action of gravity. At the same time, outside air enters the bag body 1 through the vent tube 4 and the through hole 5 to balance the internal pressure and allow the liquid to drain smoothly. After the liquid is drained, reinsert the stopper 8 into the vent tube 4 and close the valve 2.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
