[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] Example: See Figure 1-5 A portable non-alignment plastic packaging bag is shown, comprising a plastic packaging bag 1, wherein the plastic packaging bag 1 has a storage cavity 2 and a protective cavity 201, a short tube 3 connected to the protective cavity 201 is arranged on the outside of the plastic packaging bag 1, a vent 301 connected to the protective cavity 201 is provided on the short tube 3, and a sealing cover 4 is threadedly fitted on the short tube 3.
[0026] A plastic film 5 is arranged inside the storage cavity 2, and connecting ends 501 are arranged at both ends and the bottom of the plastic film 5. The connecting ends 501 are fixedly connected to the inner wall of the storage cavity 2. The plastic film 5, the connecting ends 501 and the inner wall of the storage cavity 2 together form a placement groove 502.
[0027] In this embodiment, specific reference Figure 1 A handle portion 101 is integrally formed on the top of the plastic packaging bag 1 , and a pair of plastic clips are provided on each of the handle portions 101 , and the pair of plastic clips are mutually engaged.
[0028] Among them, tea is taken as an example here. After taking the tea, when the hand no longer holds the opening of the bag open, the plastic bag of this type in the prior art will automatically close, and it is not sealed at this time. Since the plastic card strips are of equal length, the operation can be completed without alignment during use. That is, the user pinches one side of the plastic packaging bag 1 with his fingers, and then slides to the other side. The self-sealing of the plastic packaging bag 1 is achieved by the mutual engagement of a pair of the plastic card strips.
[0029] In this embodiment, specific reference Figure 1 A rectangular groove 1010 is formed on each of the pair of handle parts 101 .
[0030] Among them, by setting the rectangular groove 1010, it is convenient for users to pick up. Users can pass their fingers through the rectangular groove 1010 to complete the picking up, and it can prevent dropping during carrying.
[0031] In this embodiment, specifically refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 ; the outer surface of the short tube 3 located outside the plastic packaging bag 1 is provided with an external thread, and the inner wall of the sealing cover 4 is provided with an internal thread that matches the external thread.
[0032] Among them, the short tube 3 can be made of plastic or rubber materials. When introducing air into the protection cavity 201, it can be done by blowing with the mouth or in cooperation with a small air pump.
[0033] In this embodiment, specifically refer to Figure 4 and Figure 5 ; several hemispherical protrusions are provided on the outer surface of the sealing cover 4.
[0034] Among them, the hemispherical protrusions can be a plastic structure or a rubber structure integrally formed with the sealing cover 4, mainly playing an anti-slip role, that is, facilitating the user to remove the sealing cover 4 from the short tube 3.
[0035] In this embodiment, a blocking rod 401 is provided at the middle of one end of the sealing cover 4 facing the short tube 3, and the diameter of the blocking rod 401 is adapted to the diameter of the air vent 301.
[0036] Among them, the blocking rod 401 is made of rubber material. When screwing the sealing cover 4 onto the short tube 3, the blocking rod 401 will be inserted into the air vent 301, thereby further improving the sealing performance and preventing air leakage.
[0037] In this embodiment, specifically refer to Figure 2 and Figure 3 ; the shape of the connecting end 501 is in a "U" shape, and the connecting end 501 is made of silica gel material.
[0038] Among them, the connecting end 501 is made of silica gel material. Due to its certain elasticity, when placing the food desiccant packet, by pulling the plastic film 5, the opening of the placing groove 502 can be enlarged, thereby achieving the advantage of facilitating the placement of the food desiccant packet. At the same time, after releasing the hand, the connecting end 501 resets, and the plastic film 5 closely adheres to the food desiccant, playing a limiting role on the food desiccant to prevent it from falling off.
[0039] In this embodiment, specifically refer to Figure 2 and Figure 3 ; a food desiccant packet is placed in the placing groove 502.
[0040] Among them, the food desiccant bag is used to dry and dehumidify the tea to ensure the quality of the tea.
[0041] A portable non-alignment plastic packaging bag is disclosed. When in use, the sealing cover 4 is unscrewed counterclockwise, and the user can aim the short tube 3 with the mouth, or use a small air pump to aim the short tube 3, and deliver air into the vent 301. After the delivered air enters the protective cavity 201, the plastic packaging bag 1 is bulged as a whole. Then the sealing cover 4 is quickly screwed on clockwise, which can significantly enhance the protection of fragile items such as tea leaves placed in the storage cavity 2, and effectively prevent the items from being crushed due to accidental squeezing during transportation or storage, thereby ensuring the quality and use effect of the items.
[0042] By unscrewing the sealing cover 4 counterclockwise from the short tube 3, the air in the protective cavity 201 is discharged, so that the plastic packaging bag 1 returns to a flat state, thereby facilitating folding and storage. This design not only saves storage space, but also makes the plastic bag more convenient to carry.
[0043] By pulling the plastic film 5, the opening of the placement groove 502 can be expanded under the action of the connecting end 501, thereby achieving the benefit of facilitating the placement of the food desiccant package. At the same time, after letting go, the connecting end 501 returns to its original position, and the plastic film 5 clings to the food desiccant, limiting the food desiccant and preventing it from falling off.
[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
