Description

Technical Field

[0001] This utility model belongs to the field of bag valve technology, and more specifically, it relates to a valve for flexible packaging bags. Background Technology

[0002] Currently, for the convenience of storage and transportation, more and more wines are packaged in bags. Most of these bags are fully sealed, requiring scissors to open before drinking. When the wine cannot be finished at once, the remaining wine cannot be sealed, leading to waste and hindering the further promotion and use of bagged wines. The market expects these bagged wines to have a reusable valve to accommodate a more casual drinking lifestyle.

[0003] Based on the above, the inventors have discovered the following problem: current bag valves are equipped with switches, and these switches may be accidentally opened during use, causing the liquid inside the packaging bag to leak out and resulting in waste.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a valve for flexible packaging bags in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a valve for flexible packaging bags, thereby resolving the issue of accidental opening of valves on current packaging bags.

[0006] The purpose and function of this utility model for a valve used in flexible packaging bags are achieved by the following specific technical means:

[0007] A valve for flexible packaging bags includes a mounting plate and a valve. A threaded connector is mounted on the surface of the mounting plate, and a water leakage hole is formed on the surface of the mounting plate. The water leakage hole is located inside the threaded connector. The valve is threadedly connected to the threaded connector. The valve also includes a sealing cap. The surface of the outlet of the valve is provided with threads, and the sealing cap is provided with a threaded groove. The threads and the threaded groove are matched.

[0008] Furthermore, a connecting component is fitted onto the surface of the valve, a connecting band is installed on the surface of the connecting component, a clamp is installed at the end of the connecting band away from the connecting component, and a groove is opened on the surface of the sealing cover, with the clamp located in the groove.

[0009] Furthermore, the connecting component includes a first semicircular part and a second semicircular part, which are connected by a connecting mechanism.

[0010] Furthermore, the connecting mechanism includes a pair of first connectors installed on both sides of the first semicircular part and a pair of second connectors installed on both sides of the second semicircular part. The surface of the first connector is provided with a slot, and the surface of the second connector is provided with a locking block, which is located in the slot.

[0011] Furthermore, a rubber pad is installed on the surface where the valve connects to the threaded connector.

[0012] Furthermore, both the connecting components and the connecting mechanism are made of plastic.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model utilizes a mounting plate, valve, threaded connector, drain hole, sealing cap, thread, and thread groove in combination. In use, the mounting plate is first installed inside the flexible packaging bag, with the threaded connector on the mounting plate extending to the outside of the flexible packaging bag. Then, the valve is screwed into the threaded connector, and the thread groove inside the sealing cap is aligned with the thread on the valve for installation. The sealing cap seals the valve's outlet. This design prevents the valve from opening due to misoperation, thus avoiding the leakage of liquid from the packaging bag and improving practicality.

[0015] By using the connecting parts, connecting straps, clamps, and slots together, the sealing cap can be fixed to the valve, preventing it from being lost when removed. When the sealing cap needs to be replaced, simply remove the valve and the connecting parts and sealing cap can be removed together. Attached Figure Description

[0028] Example:

[0029] As attached Figure 1 To be continued Figure 3 As shown:

[0030] This utility model provides a valve for flexible packaging bags, including a mounting plate 1 and a valve 2. A threaded connector 3 is mounted on the surface of the mounting plate 1, and a water leakage hole 4 is opened on the surface of the mounting plate 1. The water leakage hole 4 is located inside the threaded connector 3. The valve 2 is threadedly connected to the threaded connector 3. It also includes a sealing cap 5. The surface of the liquid outlet of the valve 2 is provided with a thread 6, and the sealing cap 5 is provided with a threaded groove 7. The thread 6 and the threaded groove 7 are matched.

[0031] By using the mounting plate 1, valve 2, threaded connector 3, drain hole 4, sealing cap 5, thread 6, and threaded groove 7 together, the installation plate 1 is first installed inside the flexible packaging bag. The threaded connector 3 on the mounting plate 1 extends to the outside of the flexible packaging bag. Then, the valve 2 is screwed into the threaded connector 3. Finally, the threaded groove 7 in the sealing cap 5 is aligned with the thread 6 on the valve 2 for installation. The sealing cap 5 can seal the outlet of the valve 2. Through the above design, the problem of liquid flowing out of the packaging bag due to accidental operation of the valve 2 can be avoided, thus improving practicality.

[0032] The valve 2 is fitted with a connecting component 8, the connecting component 8 is fitted with a connecting band 9, and a clamp 10 is installed at the end of the connecting band 9 away from the connecting component 8. The sealing cover 5 is provided with a groove 11, and the clamp 10 is located in the groove 11.

[0033] By using the connecting component 8, connecting strap 9, clamp 10 and slot 11 together, the sealing cover 5 can be fixed on the valve 2, avoiding the loss of the sealing cover 5 when it is removed. When the sealing cover 5 needs to be replaced, simply remove the valve 2 and the connecting component 8 and the sealing cover 5 can be removed together.

[0034] The connecting component 8 includes a first semicircular part 801 and a second semicircular part 802, which are connected by a connecting mechanism 12.

[0035] The connecting mechanism 12 includes a pair of first connecting members 1201 installed on both sides of the first semicircular member 801 and a pair of second connecting members 1202 installed on both sides of the second semicircular member 802. The surface of the first connecting member 1201 is provided with a slot 1203, and the surface of the second connecting member 1202 is provided with a locking block 1204, which is located in the slot 1203.

[0036] With the cooperation of the first semicircular part 801, the second semicircular part 802 and the connecting mechanism 12, when the sealing cover 5 needs to be replaced, the locking block 1204 can be pushed to disengage from the edge of the groove 1203, and then the first semicircular part 801 and the second semicircular part 802 can be separated. It should be noted that one side of the locking block 1204 is inclined. When the first semicircular part 801 and the second semicircular part 802 are installed, the inclined surface of the locking block 1204 will automatically deform and store force when it contacts the groove 1203. When the locking block 1204 exceeds the groove 1203, it will rebound without the need for manual assistance. With the above design, the sealing cover 5 can be replaced without removing the valve 2.

[0037] A rubber pad 13 is installed on the surface where the valve 2 connects to the threaded connector 3.

[0038] The use of rubber gasket 13 can improve the sealing of the connection between valve 2 and threaded connector 3.

[0039] Both the connecting component 8 and the connecting mechanism 12 are made of plastic.

[0040] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
