[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] This embodiment provides a packaging bag, such as Figure 1-5 As shown, the packaging bag includes a bag body 1, and an inlet / outlet pipe 2 is installed on the upper side of the bag body 1 through a connection hole. A sealing cap structure 3 is installed on the inlet / outlet pipe 2.

[0024] The sealing cap structure 3 includes two first connecting hooks 31 that are slidably mounted on the bag body 1. A push rod 32 is mounted on the side wall of the first connecting hook 31. A spring 33 is mounted on the side wall of the push rod 32 and located outside the push rod 32. The sealing cap structure 3 also includes a cover 34 that is slidably mounted on the outer wall of the inlet / outlet pipe 2. A second connecting hook 35 is mounted on the inner wall of the cover 34 and corresponds to the first connecting hook 31.

[0025] In use, the user simultaneously drives the two pressing plates 321 towards the direction closer to the circular groove 22. The pressing plates 321 move the push rod 32, which in turn moves the first connecting hook 31 away from the circular groove 22. The first connecting hook 31 pulls the spring 33 to extend, and the first connecting hook 31 separates from the second connecting hook 35, so that the second connecting hook 35 loses the control of the first connecting hook 31. This drives the cover 34 upward, and the cover 34, along with the second connecting hooks 35 on both sides, moves out of the mounting groove 21, realizing the function of easily removing the cover 34. This avoids the problem that the cover 34 of the existing packaging bag requires a lot of force to open, and the opening process is very laborious, making the use of the packaging bag better.

[0026] In this embodiment, mounting grooves 21 are symmetrically provided on both sides of the inlet / outlet pipe 2. The inlet / outlet pipe 2 is slidably connected to the first connecting hook 31 through the mounting grooves 21. A circular groove 22 is provided on the inlet / outlet pipe 2 and on one side of the mounting groove 21. The inlet / outlet pipe 2 is fixedly connected to the other end of the spring 33 through the circular groove 22. The other end of the push rod 32 passes through the inlet / outlet pipe 2 and is provided with a pressing plate 321. The first connecting hook 31 and the second connecting hook 35 are adapted to each other. The upper side of the first connecting hook 31 and the lower side of the second connecting hook 35 are both provided with inclined surfaces.

[0027] The first connecting hook 31 has an inclined surface on its upper side and the second connecting hook 35 has an inclined surface on its lower side. When the user moves the cover 34 downwards, the cover 34 slides the second connecting hook 35 downwards from the mounting groove 21. The second connecting hook 35 moves downwards, causing the inclined surface of the second connecting hook 35 to press against the inclined surface of the first connecting hook 31. The second connecting hook 35 drives the first connecting hook 31 to move away from the circular groove 22. When the inclined surface of the second connecting hook 35 passes the inclined surface of the first connecting hook 31, the spring 33 pulls the surface of the first connecting hook 31 back to the hook surface of the second connecting hook 35 under the reset action of the spring 33, thus realizing the quick connection between the inlet / outlet pipe 2 and the cover 34.

[0028] In this embodiment, a rubber pad is installed on the inner end face of the connecting column 4;

[0029] A rubber gasket is installed on the inner end face of the connecting column 4. The rubber gasket plays a sealing role between the cover 34 and the inlet / outlet pipe 2, so that the product in the bag 1 will not leak.

[0030] Example 2

[0031] Unlike Embodiment 1, the cap 34 of the packaging bag and the packaging bag are two separate entities. In the existing packaging bag, the cap 34 is easy to lose when it is left aside after being opened. Therefore, a connecting post 4 is installed on the end face of the cap 34, and an upper ring 5 is rotatably installed on the outer wall of the connecting post 4. A nylon strap 6 is installed on the outer wall of the upper ring 5, and a lower ring 7 is installed on the end of the nylon strap 6 away from the upper ring 5.

[0032] When in use, after the cover 34 is opened, the cover 34 is rotatably connected to the upper ring 5 through the connecting post 4, so that the cover 34 is always connected to the upper ring 5. The upper ring 5 is connected to the lower ring 7 through the nylon belt 6. The lower ring 7 is rotatably connected to the inlet and outlet pipe 2, so that the cover 34 is always on one side of the inlet and outlet pipe 2, so that the cover 34 will not be lost. This avoids the problem that the cover 34 of the existing packaging bag is easily lost after being opened and left aside, and facilitates the resealing of the packaging bag.

[0033] In this embodiment, a limiting groove 23 is provided on the outer wall of the inlet / outlet pipe 2, and the inlet / outlet pipe 2 is rotatably connected to the inner wall of the lower ring 7 through the limiting groove 23.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and concept of this utility model, should be included within the scope of protection of this utility model.
