Fluid container capable of smoothly filling fluid and application thereof

Abstract

A fluid container that can be smoothly filled with fluid and its application, the fluid container includes a fluid buffer formed by plastic sealing at least two layers of fluid storage films and is equipped with at least two layers of shorter valves stacked inside the two layers of fluid storage films Membrane-formed shut-off valve in which the fluid cushioning comprises a main channel unit having a main channel and a fluid storage unit, on the bottom side of the main channel unit further comprising a main channel sealing seam comprising a sealing seam body and integrally protrudingly extending Based on the multiple drainage slits of the main body of the sealing slit, the proximal end of the stop valve extends into the main channel, and the far end of the stop valve forms fluid-filled channels with inlets respectively between the two layers of valve membranes, wherein the main channel is filled When fluid is flowing, the setting of the drainage slit makes the fluid reach the inlet of the fluid filling channel smoothly, thereby filling the fluid storage unit with fluid through the fluid filling channel, and the stop valve automatically closes the fluid filling channel after the fluid filling operation is completed.

Description

technical field [0001] The present invention relates to fluid storage devices, and more particularly to fluid containers that facilitate drainage and filling of fluids. Background technique [0002] Fluid containers, such as fluid cushions or fluid packaging bags, are widely used in the modern logistics industry. For example, the common air-packing device has strong cushioning performance because it is filled with air, and it does not need to be inflated during transportation, so it takes up a small space. When it is used, it can be inflated on site before packaging the items to be packaged, thereby reducing the cost. So this air-packing device has been widely welcomed in the market. [0003] Figure 1 to Figure 2 The structure of the existing air-packing device is illustrated, which includes two layers of outer films 1A and 1B heat-sealed together, and two layers of inner films 2A and 2B, wherein a heat-resistant layer is arranged between the two layers of inner films 2A a...

[0005] However, although in the above-mentioned technical scheme, the inflation performance is improved by setting the heat-sealing point 1E, yet the heat-sealing point 1E and the heat-sealing line 1F are spaced apart from each other, resulting in a gap between the heat-sealing point 1E and the heat-sealing line 1F. A space 1G is formed between the adventitia and the intima such as 1A and 2A. When inflated, the air enters the main airway 1D and still enters between the adjacent adventitia 1A and the intima 2A, and flows in at the position of the space 1G. Outflow, so that the air around the heat-sealing point 1E will cause the outer film 1A and the inner film 2A connected by the heat-sealing point 1E to move in the lateral direction, thereby causing the outer film 1A and the inner film 2A to be at the position of the heat-sealing point 1E produce wrinkles, such as image 3 As shown, resulting in the inflatable channel 2C can not be opened normally

[0006] That is, if figure 1 As shown in , the airflow flowing in the space 1G causes the position of the heat-sealing point 1E to move along the left-right direction, which causes the film part connected to the heat-sealing point 1E to bend and make the film in the main airway 1D form waves Shaped structure, so that some inflation channels 2C between the two inner membranes 2A and 2B will be blocked due to the bending and wrinkling of the membrane, so that they cannot be opened smoothly

[0007] In addition, in this solution, the area from the main airway 1D to the heat-sealing line 1F is a multi-layered film structure. However, when the two layers of films are attached together, they will cause local adhesion due to electrostatic adsorption. When inflated, it cannot be fully expanded due to uniform force

In addition, in the area between adjacent heat-sealing points 1E, there will be a gap between the two layers of inner film 2A and 2B, and a gap will also be formed between the outer film 1A or 1B and the inner film 2A or 2B, because there is no suitable The drainage structure causes the airflow to move in these gaps, and the local intima is unevenly stressed, so that the entrance of some inflation channels 2C is blocked, and it cannot be inflated smoothly
