Description

Technical Field

[0001] This application relates to the technical field of packaging bags, and in particular to a quick-connect valve. Background Technology

[0002] This connector valve is used on liquid packaging. It is installed on the packaging bag. When in use, the relevant liquid extraction device is inserted, passes through the slit, and enters the packaging bag to extract the liquid. During the transportation of the packaging bag, the anti-bulge contacts the slit, so that the liquid inside the packaging bag will not flow out from the slit when under pressure.

[0003] The entire body of the connector valve is injection molded by a single-color injection molding machine, and then a blocking membrane is installed. After that, the blocking membrane is pressed tightly onto the body by a fixing ring to form a complete product. However, this setup requires the processing of multiple parts and then assembly, resulting in many production steps and material waste, which needs to be improved. Utility Model Content

[0004] The purpose of this application is to provide a quick-connect valve to reduce material waste.

[0005] This application provides a quick-connect valve with the following technical solution: it includes an upper cover and a lower cover connected to the upper cover. The upper cover has a first channel, and the lower cover has a second channel. The upper cover has a flip cover for covering the first channel. A blocking membrane is connected to the upper cover and covers the first channel. The blocking membrane has a slit. The flip cover has a blocking post for contacting the slit. The blocking membrane is integrally formed with the upper cover. The blocking membrane has an extended positioning part, and the upper cover has a positioning groove for cooperating with the extended positioning part.

[0006] By adopting the above technical solution, the barrier membrane and the upper cover are integrally formed, avoiding the assembly of multiple parts, reducing production steps, and reducing material waste. The extended positioning part cooperates with the positioning groove to accurately position the barrier membrane, ensuring its stable coverage of the first channel. The extended positioning part increases the area of ​​the barrier membrane and the upper cover integrally formed, improving the stability of the integral formation of the barrier membrane and the upper cover.

[0007] Optionally, the barrier membrane is provided with a fixing part, and the upper cover is provided with a fixing groove, which is used to cooperate with the fixing part.

[0008] By adopting the above technical solution, the fixing part of the barrier membrane cooperates with the fixing groove of the upper cover, increasing the contact area between the barrier membrane and the upper cover, and further enhancing the connection stability between the barrier membrane and the upper cover.

[0009] Optionally, the upper cover is provided with a snap-fit ​​block, and the flip cover is provided with a snap-fit ​​groove, which is used to snap-fit ​​with the snap-fit ​​block.

[0010] By adopting the above technical solution, and by setting up a snap-fit ​​block and a snap-fit ​​groove to engage with it, a secure connection can be achieved between the flip cover and the upper cover, preventing the flip cover from opening arbitrarily and ensuring the stability of the seal of the liquid packaging bag. At the same time, this structure is simple, easy to operate, and improves ease of use.

[0011] Optionally, two of the snap-fit ​​blocks are disposed on the upper cover, and the number of snap-fit ​​slots is the same as the number of snap-fit ​​blocks, with each snap-fit ​​block corresponding to one of the snap-fit ​​slots.

[0012] By adopting the above technical solution, the two snap-fit ​​blocks and the corresponding number of snap-fit ​​slots are snap-fitted together one by one, which can make the flip cover more securely connected to the upper cover and enhance the stability of the connection between the flip cover and the upper cover.

[0013] Optionally, the flip cover is provided with a protrusion, and the upper cover is provided with a groove, the groove being used to engage with the protrusion.

[0014] By adopting the above technical solution, when the snap-fit ​​block and the snap-fit ​​groove are engaged, the protrusion is located in the groove. The groove restricts the horizontal movement of the protrusion, which in turn restricts the movement of the flip cover, thus enhancing the stability of the connection between the flip cover and the upper cover.

[0015] Optionally, the upper cover is provided with two limiting blocks at intervals, and a receiving groove is formed between the two limiting blocks. The receiving groove is used to cooperate with the flip cover and is connected to the first channel.

[0016] By adopting the above technical solution, when the snap-fit ​​block and the snap-fit ​​groove are engaged, the flip cover is located in the receiving groove, and the two limiting blocks restrict the horizontal movement of the flip cover, thereby enhancing the stability of the connection between the flip cover and the upper cover.

[0017] Optionally, the flip cover is provided with a positioning protrusion ring, which surrounds the blocking post and is used to abut against the inner wall of the first channel.

[0018] By adopting the above technical solution, when the snap-fit ​​block and the snap-fit ​​groove are engaged, the outer peripheral surface of the positioning protrusion ring abuts against the inner wall of the first channel. The inner wall of the first channel restricts the horizontal movement of the positioning protrusion ring, that is, it restricts the movement of the flip cover, thereby enhancing the stability of the connection between the flip cover and the upper cover.

[0019] Optionally, the upper cover is provided with a limiting protrusion ring, which surrounds the opening of the first channel, and the flip cover is provided with a limiting ring groove, which is used to cooperate with the limiting ring groove.

[0020] By adopting the above technical solution, when the snap-fit ​​block and the snap-fit ​​groove are engaged, the limiting protrusion is located in the limiting ring groove. The limiting protrusion restricts the horizontal movement of the flip cover, thereby enhancing the stability of the connection between the flip cover and the upper cover.

[0021] Optionally, the lower cover is provided with a snap-fit ​​hook, the upper cover is provided with a mounting groove, the inner wall of the mounting groove is provided with a snap-fit ​​protrusion, and the snap-fit ​​hook engages with the snap-fit ​​protrusion.

[0022] By adopting the above technical solution, the snap hook of the upper cover engages with the snap protrusion on the inner wall of the mounting groove to achieve the snap-fit ​​function and ensure the stability of the connection between the upper cover and the lower cover.

[0023] Optionally, the lower cover is provided with a support portion, which is used to abut against the upper cover.

[0024] By adopting the above technical solution, the support part plays a supporting role for the upper cover, thereby improving the stability of the upper cover when installed on the lower cover.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The barrier membrane and the upper cover are integrally molded, avoiding the assembly of multiple parts, reducing production steps, and minimizing material waste. The extended positioning part cooperates with the positioning groove to accurately position the barrier membrane, ensuring its stable coverage of the first channel. The extended positioning part increases the area of ​​the barrier membrane and the upper cover integrally molded, improving the stability of the integral molding of the barrier membrane and the upper cover.

[0027] 2. The fixing part of the barrier membrane cooperates with the fixing groove of the upper cover, which increases the contact area between the barrier membrane and the upper cover, and can further enhance the connection stability between the barrier membrane and the upper cover.
