Description

Technical Field

[0001] The utility model relates to the technical field of liquid packaging and transportation, and particularly relates to a liquid packaging bag using gas inflation to assist in unloading. Background Art

[0002] A liquid packaging bag is a container capable of storing and transporting various non-hazardous liquid goods. In non-hazardous liquid transportation, it can replace expensive traditional packaging such as tank containers and iron drums. Each flexible liquid packaging bag made of plastic is exactly placed in a turnover folding box, and the large specification can store and transport 500L - 1400L of liquid.

[0003] When unloading the goods in the liquid bag, it is necessary to open the top cover and insurance of the liquid packaging bag, connect the joint of the delivery hose with the valve on the liquid packaging bag, then send the delivery hose to the outside of the container through the opening at the bottom of the container, and then open the valve to unload the goods.

[0004] However, unloading liquid materials in this way completely relies on the self-gravity of the liquid materials. Especially when the viscosity of the liquid materials is relatively high, the unloading speed will be relatively slow, and in the later stage of unloading, the liquid packaging bag will spread on the bottom of the container, resulting in a large amount of liquid being unable to be discharged. This requires manual dragging of the liquid packaging bag to pour out the remaining liquid, which is time-consuming and laborious. Content of the Utility Model

[0005] In order to effectively solve the technical problems in the background art, the main purpose of the utility model is to provide a liquid packaging bag using gas inflation to assist in unloading, so that liquid goods can be discharged quickly without manual assistance.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A liquid packaging bag using gas inflation to assist in unloading includes a packaging bag body and an inflation structure; the packaging bag body is used for containing liquid materials, and a filling valve for loading and a discharge valve for discharging are respectively arranged on both sides of the packaging bag body;

[0008] Before inflation, the inflation structure is placed between the packaging bag body and the container, so that a part of the inflation structure is attached to the packaging bag body, and the rest extends upward to the outside of the packaging bag body; an inflation valve is located at the top of the inflation structure;

[0009] After inflation, the top of the inflated inflation structure is a certain distance higher than the top of the packaging bag body.

[0010] Further, the inflation structure is an inflation bag.

[0011] Further, the unfolded area of the inflation structure is not larger than the unfolded area of the packaging bag body.

[0012] Further, the deployment area of the inflatable structure is more than 50% of the deployment area of the packaging bag body.

[0013] Further, the filling valve is located at the center of the packaging bag body.

[0014] Further, the bottom of the inflatable structure is located between the bottom of the packaging bag body and the filling valve.

[0015] Further, the discharge valve is located at a certain distance above the bottom of the packaging bag body.

[0016] Further, the inflatable structure is fixedly connected to the side of the packaging bag body where the discharge valve is provided.

[0017] Further, more than 50% of the deployment area of the inflatable structure is pasted to the packaging bag body, and a part of the inflatable structure is pasted on the packaging bag body, and the rest extends to the outside of the top of the packaging bag body.

[0018] Furthermore, the inflatable structure is fixed on the packaging bag body in a horizontally centered form, and the width of the inflatable structure is smaller than the width of the packaging bag body.

[0019] Compared with the prior art, the present utility model has the following beneficial effects:

[0020] In the liquid packaging bag of the present utility model, by providing an inflatable structure on one side of the packaging bag body, the inflatable bag gradually inflates and expands during unloading and squeezes the packaging bag body, so that the liquid material can be discharged more quickly and completely. It is especially suitable for unloading highly viscous liquids.

[0021] If a part of the inflatable bag is pasted on the packaging bag body and the rest extends to the outside of the top of the packaging bag body, before unloading, the part of the inflatable bag exceeding the packaging bag body can be placed on the edge of the container, which is convenient for the operator to perform the inflation operation. In addition, since the top of the inflatable bag is higher than the top of the packaging bag body by a certain distance, as the inflation progresses, the inflatable bag can gradually expand and exceed the top of the container, which can play a role in supporting and suspending the packaging bag body.

[0025] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0026] Embodiment 1

[0027] As Figure 1-2 shown, a liquid packaging bag using inflatable auxiliary unloading includes a packaging bag body 1 and an inflatable structure 2; the packaging bag body is used for containing liquid materials, and a filling valve 11 for loading and a discharging valve 12 for discharging are respectively arranged on both sides of the packaging bag body; preferably, the filling valve 11 is located at the center of the packaging bag body, and the discharging valve 12 is located at a certain distance above the bottom of the packaging bag body.

[0028] One side of the inflatable structure is provided with an inflation valve 21 for connecting an air pump; before filling, the inflatable structure is placed between the packaging bag body and the container, and the gradually expanding inflatable structure is used to accelerate the discharge of the liquid in the packaging bag body.

[0029] The inflation valve 21 is located on the side of the inflatable structure facing away from the packaging bag body;

[0030] Preferably, the inflatable structure 2 is an inflatable bag; the unfolded area of the inflatable bag is not larger than the unfolded area of the packaging bag body 1, so as to save the inflation time; in order to enable the expanded inflatable bag to squeeze out the liquid in the packaging bag body as much as possible, preferably, the unfolded area of the inflatable bag is more than 50% of the area of the packaging bag body.

[0031] The top of the inflatable bag is higher than the top of the packaging bag body by a certain distance, and the inflation valve 21 is located at the top of the inflatable bag. Thus, before unloading, the part of the inflatable bag exceeding the packaging bag body 1 can be placed on the edge of the container, which is convenient for the operator to perform the inflation operation.

[0032] Embodiment 2

[0033] In Embodiment 1, the packaging bag body and the inflatable structure are independent of each other and have no connection relationship; in this embodiment, the inflatable bag is fixed to the side of the packaging bag body where the discharging valve 12 is provided by means of pasting, etc.; in this way, as the inflatable bag expands, the packaging bag body adhered to the inflatable bag will not be completely spread on the ground to affect the discharging, so that the residue and waste of the materials can be minimized to the greatest extent without manual assistance.

[0034] Preferably, the inflatable bag is not entirely adhered to the packaging bag body 1. Instead, more than 50% of the unfolded area of the inflatable bag is adhered to the packaging bag body, and the remaining part extends to the outside of the top of the packaging bag body. Specifically, the inflatable bag is fixed to the packaging bag body 1 in a centered position left and right, and the width of the inflatable bag is smaller than the width of the packaging bag body 1;

[0035] In addition, since the top of the inflatable bag is a certain distance higher than the top of the packaging bag body 1, as inflation progresses, the inflatable bag can gradually expand and exceed the top of the container, which can support and suspend the packaging bag body.

[0036] More preferably, the bottom of the inflatable structure is located between the bottom of the packaging bag body 1 and the filling valve 11.

[0037] Working principle:

[0038] Close the discharge valve on the packaging bag body, and fill the liquid material into the packaging bag body through the filling valve; before unloading, connect the connector of the conveying hose to the valve on the liquid packaging bag, and then send the conveying hose through the opening at the bottom of the container to the unloading box outside the container; when unloading, open the discharge valve on the packaging bag body and at the same time open the inflation valve on the inflatable bag, so that the inflatable bag gradually expands and squeezes the packaging bag body, causing the liquid material to be continuously discharged.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
