The fluid container with the fluid blocking body backflow heat sealing line is provided with the fluid blocking body backflow heat sealing line, so that fluid leakage of the fluid container can be better prevented, and the buffering effect of packaged articles can be better achieved.
Specifically, in the above preferred embodiment, the fluid container having the fluid blocking body backflow heat sealing line includes at least one fluid buffer body 10, that is, one fluid container is formed by one fluid buffer body 10 or a plurality of fluid buffer bodies 10 are connected by plastic sealing, such as bonding or heat sealing, to form the three-dimensional fluid container. In an example of a preferred embodiment of the invention, it is formed by one said fluid cushion body 10. More specifically, the fluid buffer body 10 comprises at least two layers of container films 11 and 12 and at least two layers of valve films 21 and 22, which are plastically molded by a series of plastic molding lines 30 to form the fluid container comprising one or more connected fluid storage units 13, wherein a fluid storage chamber 14 capable of storing fluid is formed in each fluid storage unit 13.
In the above preferred embodiment, as shown in fig. 1A, the structure of the stop valve 20 of the present invention is schematically illustrated.

When fluid is injected into the fluid storage chamber 14 through the fluid inlet channel 23 and the pressure in the fluid storage chamber 14 reaches a predetermined requirement, the pressure in the fluid storage chamber 14 acts on the valve films 21 and 22 to make the valve films 21 and 22 adhere to one of the container films 21 or 22, thereby closing the fluid injection channel 23 so that the shut-off valve 20 functions as a one-way valve. In one embodiment, a positioning mark block 24 is disposed between the valve films 21 and 22 of the stop valve 20 and attached to the valve films 21 or 22, the positioning mark block 24 is a heat-resistant layer made of a heat-resistant material such as heat-resistant ink, and when fluid is injected into the fluid buffer 10, the valve films 21 and 22 are more easily opened, so that the fluid can be injected into the fluid storage chamber 14 through the fluid inlet channel 23 more smoothly.

More specifically, the container film 11 or 12 and the valve film 21 or 22 are molded to form the stop valve 20 having two valve film molding lines 33, and the valve film molding lines 33 are used to form fluid injection ports for fluid to enter the fluid storage unit 13. The fluid buffering body 10 further includes a main channel unit 15 connected to each of the fluid storage units 13, and preferably, integrally extended from each of the fluid storage units 13. More specifically, in one embodiment, the main passage unit 15 is perpendicular to the extending direction of the fluid storage unit 13. Wherein the main channel unit 15 has a main channel 151, and when a fluid is injected from the main channel 151 of the main channel unit 15, the fluid flows through the fluid inlet channel 23 to inject the fluid into the fluid storage chamber 14. When a predetermined pressure is reached in each of the fluid storage chambers 14, the valve films 21 and 22 of the shut-off valve 20 are attached to one of the container films 11 or 12, thereby achieving self-sealing to prevent the re-permeation of the gas into the main channel 151.
It is to be understood that the main passage unit 15 may be formed of two layers of the container films 11 and 12, two layers of the valve films 21 and 22, or one of the container films 11 or 12 and one of the valve films 21 or 22.
As shown in fig. 2 and 3, the plastic sealing line 30 further includes an extending plastic sealing line 34, that is, the longitudinal plastic sealing line 32 extends and intersects with the valve film plastic sealing line 33, and the longitudinal plastic sealing line 32 further extends to the main channel unit 15 but does not intersect with the transverse plastic sealing line 32, that is, the portion of the longitudinal plastic sealing line 32 extending out of the valve film plastic sealing line 33 is the extending plastic sealing line 34. Wherein when the main channel 151 of the main channel unit 15 is filled with fluid, the extended plastic wire 34 can guide the fluid to smoothly flow through the fluid inlet channel 23 to fill the fluid storage chamber 14 with fluid. When fluid is injected from the main channel 151 of the main channel unit 15, the valve films 21 and 22 are made to be more easily opened, so that fluid is more smoothly injected into the fluid storage unit 13, and the injection efficiency of fluid is improved.
As shown in fig. 1B and 3, fluid is injected through the main channel 151 of the main channel unit 15, and fluid is injected into the fluid storage chamber 14 through the fluid inlet channel 23, so that the fluid buffer body 10 is filled with fluid to achieve a buffering effect, and after the fluid buffer body 10 is filled with fluid, the fluid is transversely plastic-molded within the length range of the extension plastic-molding line 34 to form the sealing line 35. The sealing line 35 and the extended plastic sealing line 34 form one or more attached fluid storage units 16, the fluid storage unit 13 and the attached fluid storage unit 16 form a closed body which can prevent the fluid of the fluid storage unit 13 from flowing back, so that the fluid is retained in the closed body, and a perfect buffering effect is achieved.

Wherein when the main channel 151 of the main channel unit 15 is filled with fluid, the extended plastic wire 36 can guide the fluid to smoothly flow through the fluid inlet channel 23 to fill the fluid storage chamber 14 with fluid. More specifically, the extended molding line 36 is closer to the positioning mark block 24 of the shut-off valve 20 due to the upper and lower lengths and the left and right widths of the extended molding line 36. When fluid is injected from the main channel 151 of the main channel unit 15, the valve films 21 and 22 are made to be more easily opened, so that fluid is more smoothly injected into the fluid storage unit 13, and the injection efficiency of fluid is improved.
In one embodiment, the plastic sealing line 30 further comprises a flow-blocking plastic sealing line 37, and the flow-blocking plastic sealing line 37 intersects with the longitudinal plastic sealing line 32 and the extension plastic sealing line 36. When the fluid is injected into the fluid storage chamber 14 formed by the fluid storage unit 13, the internal pressure of the fluid storage chamber 14 acts on the valve films 21 and 22, and the flow-blocking plastic line 37 can block the backflow of the fluid in the fluid storage chamber 14, so that the valve films 21 and 22 are more attached to one of the container films 21 or 22, thereby closing the fluid injection channel 23 and achieving a better sealing effect. It should be noted that, in an embodiment, the extending plastic package line 36 and the current blocking plastic package line 37 may be integrally formed by plastic molding.
