Description

Technical Field

[0001] The utility model belongs to the technical field of transportation packaging bags, and particularly relates to a special FIBC liquid bag. Background Art

[0002] The FIBC liquid bag is a medium-sized flexible container bag, also known as a ton bag or space bag, usually made of polyethylene (PE film) and polypropylene (PP cloth). It is a soft and bendable sealed packaging container. Due to its advantages of high tightness, firmness, safety, and convenient handling and transportation, it is widely used in the turnover and transportation operations of materials such as fish pond farming, food, and chemical raw materials. In order to improve the firmness of the liquid bag, a PP cloth protective layer is usually sleeved outside the PE film bag body. The liquid bag is connected to a feed pipe at the top. Due to the double-layer structure of the feed pipe, during the feeding process, once the inner layer and the outer layer of the feed pipe are separated, the liquid material is very likely to be discharged into the gap between the inner bag and the outer bag, resulting in a large amount of waste of the liquid material, and at the same time seriously affecting the feeding speed and the service life of the transportation bag.

[0003] In addition, the two ends of the sling in the existing liquid bag are usually fixed on the same side wall of the bag body. For example, the utility model patent with the publication number CN204979873U previously applied by the applicant discloses a high-strength and large-capacity container bag, in which the handle is directly fixed on the longitudinal strap on the side wall of the bag body. During the process of lifting the liquid bag, the two adjacent side walls of the liquid bag are subjected to the pulling forces of different slings, and it is very easy to tear the liquid bag along the edge line, resulting in liquid leakage. Therefore, there is an urgent need for a more stable, firm, and long-life special liquid container bag. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a stable, firm, and long-life special FIBC liquid bag that can avoid material leakage.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a special FIBC liquid bag, including a bag body. The bag body is surrounded by a rectangular top wall, a rectangular bottom wall, and four side walls sealed and connected between the top wall and the bottom wall. A feed pipe communicating with the inner cavity of the bag body is connected to the top wall. Both the bag body and the feed pipe are composed of an inner layer and an outer layer. The inner layer is a PE film layer, and the outer layer is a PP cloth layer. The feature is that the length of the inner layer of the feed pipe is greater than the length of the outer layer of the feed pipe. The end of the inner layer of the feed pipe is turned outward to form a folded section, and the folded section is connected to the outer wall of the outer layer of the feed pipe. Suspenders are provided at the four corners of the top of the bag body, and the two ends of the suspenders are respectively fixed on two adjacent side walls. The part of the suspender protruding from the bag body forms a lifting ring.

[0006] Further, the two ends of the suspender are respectively sewn and fixed on the outer wall of the outer layer of the bag body.

[0007] Furthermore, the top of the folded section overlaps with the top of the outer layer of the material pipe.

[0008] Furthermore, the folded section is fixedly stitched to the outer layer of the material pipe.

[0009] Furthermore, the inner layer is arranged in close fit with the outer layer.

[0010] Furthermore, a strap is fixedly connected to the outer wall of the outer layer of the material pipe.

[0011] Furthermore, the material pipe is connected to the center of the top wall of the bag body.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Since the folded section formed by the outward folding of the end of the inner layer of the material pipe is connected to the outer wall of the outer layer of the material pipe, the inner layer and the outer layer of the material pipe cannot be separated from each other, thus ensuring the stability of the material pipe during the feeding process, preventing the material from being wrongly discharged between the inner layer and the outer layer of the bag body, ensuring the normal use of the liquid bag, and prolonging the service life of the liquid bag; at the same time, since the two ends of the sling are respectively fixed on two adjacent side walls of the bag body, the tension between the adjacent side walls is quite equal during the process of lifting the bag body, thus preventing the connection part of the side walls from being torn and causing liquid leakage, and improving the overall stability of the liquid bag.

[0014] 2. Since the two ends of the sling are respectively fixedly stitched to the outer wall of the outer layer of the bag body, it can not only ensure the firm connection between the sling and the bag body, but also be convenient for processing and improve the production efficiency.

[0015] 3. Since the top of the folded section overlaps with the top of the outer layer of the material pipe, the feeding port of the material pipe is a three-layer structure, greatly improving the strength of the feeding port, preventing the feeding port from being damaged and causing liquid leakage, and improving the reliability of the feeding process.

[0016] 4. Since the folded section is fixedly stitched to the outer layer of the material pipe, the inner layer and the outer layer of the material pipe are firmly fixedly connected together, and the processing is convenient and the strength is reliable.

[0017] 5. Since a strap is fixedly connected to the outer wall of the outer layer of the material pipe, the material pipe can be tied and closed after the feeding is completed, preventing the liquid from overflowing during the transportation of the liquid bag.

[0018] 6. Through the improvement of the material pipe and sling structures, the present utility model greatly improves the stability and firmness of the liquid bag, effectively prolongs the service life of the liquid bag, and is worthy of being popularized and used in the industry.

[0023] When the present utility model is in the working state, the end close to the ground is defined as the bottom end, and correspondingly the other end far from the ground is defined as the top end; the side facing the inner cavity of the bag body is defined as the inner side, and correspondingly the side far from the inner cavity of the bag body is defined as the outer side.

[0024] The following further describes the present utility model in conjunction with the embodiments in the drawings:

[0025] As Figure 1 shown, the present utility model provides a special bag for FIBC liquid. The bag body 1 is surrounded by a rectangular top wall 11, a rectangular bottom wall 12, and four side walls 13 hermetically connected between the top wall 11 and the bottom wall 12. A material pipe 2 communicating with the inner cavity of the bag body 1 is connected in the center of the top wall 11. Both the bag body 1 and the material pipe 2 are composed of an inner layer and an outer layer, and the inner layer and the outer layer are arranged in a fitting manner. The inner layer adopts a PE film layer with high sealing performance, and the outer layer adopts a PP cloth layer with wear resistance and tensile strength. As Figure 2 shown, the length of the inner layer of the material pipe 2 is greater than the length of the outer layer of the material pipe 2. The end of the inner layer of the material pipe 2 is turned outward to form a folding section 20, and the folding section 20 is fixedly sutured to the outer wall of the outer layer of the material pipe 2 through a suture. During the feeding process, the liquid material can only flow into the inner cavity of the bag body 1 along the inner wall of the material pipe 2, thereby avoiding liquid flowing between the inner layer and the outer layer of the bag body 1 and causing damage to the liquid bag. In order to improve the strength of the material opening, the top of the folding section 20 overlaps with the top of the outer layer of the material pipe 2, so that the material opening has a three-layer structure. During the feeding process, the material opening with the three-layer structure is more stable and reliable. In order to facilitate closing the material opening, a binding band (not shown in the figure) is fixedly connected to the outer wall of the outer layer of the material pipe 2. After the feeding is completed, the material pipe 2 can be tied and closed through the binding band to avoid leakage of the liquid material during transportation.

[0026] Suspenders 3 are provided at the four corners of the top of the bag body 1. The two ends of the suspenders 3 are respectively sutured and fixed to two adjacent side walls 13 of the outer layer of the bag body 1. The part of the suspenders 3 protruding from the bag body 1 forms suspension rings 30, so that the pulling force between two adjacent side walls 13 of the bag body 1 is equivalent during the lifting process, thereby avoiding the connection part of the side walls 13 from being torn. The suspension rings 30 can cooperate with a crane or a forklift to carry the liquid bag. The shape of the suspension rings 30 is an isosceles triangle, which can ensure that the liquid bag is more stable during the lifting process and avoid damage caused by the shaking of the liquid bag.

[0027] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in any other form. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model.
