Description

Technical Field

[0001] This utility model relates to the field of valve bag technology, specifically to a liquid leak-proof valve bag. Background Technology

[0002] Currently, valve bags refer to bags with valves at the top or bottom for filling the bag with material. Most valve bags on the market use a heat-sealing method for their valves to ensure sealing performance. Although this improves the sealing performance, the valve must have a heat-sealable plastic coating (such as PE film), which increases manufacturing and usage costs. In addition, heat-sealed valves are disposable products, and the sealing effect is completely lost once the valve is opened. If the material in the bag is not completely used up, the remaining material in the bag is prone to contamination or leakage.

[0003] Therefore, the applicant hereby proposes a liquid leak-proof valve pocket to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a liquid leak-proof valve bag.

[0005] The technical solution of this utility model is as follows: This utility model provides a liquid leak-proof valve bag, including a bag body, a valve port consisting of an outer valve port and an inner valve port, and a folded inner liner; the outer valve port is provided on the outer side of the top of the bag body, and the inner valve port is connected to the inner end of the outer valve port; the folded inner liner is provided on the side of the top of the bag body below the valve port, and the outer valve port can be folded and inserted into the folded inner liner.

[0006] Furthermore, the outer valve port is 5-15 cm long, and the inner valve port is 10-40 cm long.

[0007] Furthermore, the bag has a double-layer structure, including an inner bag and a waterproof membrane covering the outside of the inner bag.

[0008] The beneficial effects achieved by this utility model are as follows: The liquid leak-proof valve bag provided by this utility model can quickly achieve a sealing effect through the cooperation of the bag body, valve port and folded inner liner. When the material in the bag is not completely used up, the outer valve port can be folded and inserted into the folded inner liner to achieve the function of repeated sealing of the valve port, so as to avoid contamination or leakage of the remaining material in the bag. Its manufacturing and use costs are low. Attached Figure Description

[0012] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are clearly described below with reference to the accompanying drawings. Obviously, the specific embodiments described are merely preferred embodiments of this utility model, and not all embodiments.

[0013] like Figure 1-3 As shown, this utility model provides a liquid leak-proof valve bag for filling paste-like waterproof coatings; it includes a bag body 1, a valve port 2 consisting of an outer valve port 21 and an inner valve port 22, and a folded inner liner 3; the outer valve port 21 is provided on the outer side of the top of the bag body 1, and the inner valve port 22 is connected to the inner end of the outer valve port 21. The outer valve port is 5-15 cm long, and the inner valve port is 10-40 cm long. The folded inner liner 3 is provided on the side of the top of the bag body 1 below the valve port 2. The outer valve port 21 can be folded and inserted into the folded inner liner 3; the material is filled through the valve port 2 composed of the outer valve port 21 and the inner valve port 22 at the top of the bag body 1. When the bag body 1 is filled with paste-like waterproof coatings, its internal air pressure will rise, and the outer valve port 21 can be directly folded and inserted into the folded inner liner 3. At this time, the outer valve port 21, the inner valve port 22, and the folded inner liner 3 will all be squeezed upward by the internal air pressure of the bag body 1 and automatically and tightly closed with the inner wall of the bag body 1, thereby effectively preventing material leakage.

[0014] The bag body 1 has a double-layer structure, including an inner bag 11 and a waterproof membrane 12 covering the outside of the inner bag 11; the structure of inner bag + outer waterproof membrane achieves water impermeability and avoids leakage of the paste-like waterproof coating (liquid) filled inside.

[0015] The inner bag 11 includes, but is not limited to, plastic bags, woven bags, etc., and in this embodiment, it is preferably a plastic bag. This invention not only achieves a quick sealing effect through the combination of the bag body, valve, and folded inner lining, but also allows for repeated sealing of the valve by folding the outer valve and inserting it into the folded inner lining when the material inside the bag is not completely used up. This prevents the remaining material inside the bag from being contaminated or leaking, and its manufacturing and usage costs are low.

[0016] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
