[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-7 This utility model provides a technical solution: a plastic flexible tube packaging bag, including a tube body 1, a discharge cylinder 7 fixed at the top of the tube body 1, a spiral pattern fixed on the outer side of the discharge cylinder 7, a connecting nozzle 6 threadedly connected to the outer side of the spiral pattern, a guide cylinder 11 fixed at the top of the inner side of the connecting nozzle 6, the bottom end of the outer side of the guide cylinder 11 slidably connected to the discharge cylinder 7, a plurality of flow control holes 12 are opened at the top of the inner side of the guide cylinder 11, a discharge nozzle 5 is fixed at the top of the connecting nozzle 6, a sealing disc 8 is rotatably connected between the discharge nozzle 5 and the guide cylinder 11, a plurality of flow control holes 13 are opened inside the sealing disc 8, and the flow control holes 12 and the flow control holes 13 are slidably connected; When the user needs to use the cosmetic liquid inside the tube 1, the flip cover 3 is opened to separate from the nozzle 5. At this time, the tube 1 is squeezed to squeeze out the cosmetic liquid inside, so that the cosmetic liquid is discharged from the inside of the tube 1 along the discharge cylinder 7, the first control hole 12, the second control hole 13 and the discharge hole, thereby effectively squeezing out the cosmetic liquid for use. To prevent leakage and contamination of the cosmetic liquid inside the tube 1, the opening and closing lever 4 is moved to drive the annular wheel 9 and the sealing disc 8 to rotate between the discharge cylinder 7 and the discharge nozzle 5. This causes the sealing disc 8 and the guide cylinder 11 to rotate relative to each other, so that the control hole 2 13 and the control hole 12 slide relative to each other, so as to effectively block and protect the cosmetic liquid inside the tube 1. The top of the guide tube 11 and the inner side of the connecting nozzle 6 are rotatably connected to an annular wheel 9, and the top of the inner side of the annular wheel 9 is fixed to the sealing disc 8. Specifically, by rotating the top of the sealing disc 8 and the top of the guide cylinder 11, the sealing disc 8 causes the control hole 2 13 and the control hole 12 at the top of the guide cylinder 11 to rotate relative to each other. When the control hole 2 13 and the control hole 12 overlap, the cosmetic liquid inside the tube 1 is effectively discharged along the discharge cylinder 7, the guide hole, the guide cylinder 11, the control hole 12, the control hole 2 13 and the discharge hole, so as to facilitate the effective discharge of the cosmetic liquid for use. A groove is provided on the outer side of the connecting nozzle 6, and an opening and closing lever 4 is slidably connected to the inner side of the groove. One end of the opening and closing lever 4 is fixed to the annular wheel 9, and anti-slip particles are fixed on the outer side of the opening and closing lever 4. When it is necessary to protect the cosmetic liquid inside the tube 1, the opening and closing lever 4 is moved to cause the annular wheel 9, the sealing plate 8 and the flow control hole 2 13 to be misaligned with the flow control hole 12, so that the sealing plate 8 can effectively block and protect the cosmetic liquid discharged inside the tube 1. A sealing ring 10 is fixed at the bottom of the inner side of the discharge cylinder 7. The outer side of the sealing ring 10 is slidably connected to the guide cylinder 11. A guide hole is provided at the connection between the discharge cylinder 7 and the pipe body 1. Furthermore, the cosmetic liquid inside the tube 1 is effectively conducted through the sealing ring 10, the guide hole, and the guide tube 11; The top of the inside of the discharge nozzle 5 is provided with a discharge hole. One end of the top of the discharge nozzle 5 is rotatably connected to a flip cover 3. One end of the top of the inside of the discharge nozzle 5 is provided with a ring wheel 9. One end of the bottom of the flip cover 3 is fixed with a locking block 15. The bottom of the locking block 15 is slidably connected to the ring wheel 9. Specifically, the flip cover 3 drives the locking block 15 to engage with the inner side of the annular wheel 9, thereby effectively closing the flip cover 3 and the dispensing nozzle 5, further promoting the protective and sealing effect of the cosmetic liquid. Both ends of the tube body 1 are fixed with connecting frames 2. The ends of the two connecting frames 2 that are close to each other are rotatably connected to the extrusion rollers 14. When it is necessary to squeeze out the cosmetic liquid inside the tube body 1, the tube body 1 is wrapped around the outside of the extrusion rollers 14. By wrapping and squeezing the extrusion rollers 14, the cosmetic liquid inside the tube body 1 is discharged from the discharge nozzle 5 and the discharge hole.

[0023] The usage process of the plastic tube packaging bag provided by this utility model is as follows: When not in use, the packaging bag is in a double-sealed protective state. On the one hand, the flip cover 3 is locked by the sliding buckle 15 at the bottom and the annular wheel 9 at the top of the inner end of the dispensing nozzle 5, thus sealing the dispensing hole at the top of the dispensing nozzle 5; on the other hand, the flow control hole 13 of the sealing disc 8 and the flow control hole 12 of the guide tube 11 are in a cross-staggered state, blocking the flow path of the cosmetic liquid inside the tube 1. At the same time, the sealing ring 10 at the bottom of the inner side of the dispensing tube 7 slides and fits against the guide tube 11, further strengthening the seal and preventing the cosmetic liquid from leaking out. Then, when the cosmetic liquid needs to be used, the first step is to rotate the flip cover 3 to disengage the locking block 15 from the annular wheel 9 and release the initial seal of the dispensing nozzle 5; the second step is to move the opening and closing lever 4 in the outer groove of the connecting nozzle 6 (the anti-slip particles on its outer side can improve the operating feel). The opening and closing lever 4 drives the annular wheel 9 fixed thereto to rotate, and the annular wheel 9 then drives the sealing disc 8 fixed at the top of the inner side to rotate between the dispensing nozzle 5 and the guide tube 11 until the flow control hole 2 13 and the flow control hole 12 completely overlap, opening the flow channel of the cosmetic liquid. The third step involves squeezing out the cosmetic liquid in two ways: one is to directly squeeze the tube body 1, and the cosmetic liquid enters the discharge cylinder 7 through the guide hole at the connection between the tube body 1 and the discharge cylinder 7, then passes through the sealing ring 10 and enters the guide cylinder 11, and then passes through the overlapping control holes 12 and 13 in sequence, and is discharged from the discharge hole of the discharge nozzle 5. Secondly, the tube body 1 is wrapped around the outside of the extrusion roller 14 of the bottom connecting frame 2, and the residual cosmetic liquid is discharged through the above path by wrapping and extrusion. After use, reverse the opening and closing lever 4 to drive the annular wheel 9 and sealing disc 8 to rotate, so that the flow control hole 2 13 and the flow control hole 12 cross and misalign again, blocking the flow of cosmetic liquid. Then rotate the flip cover 3 to make the locking block 15 and the annular wheel 9 lock together again, restoring the double sealing state.

[0024] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
