Embodiment 1

[0030] This embodiment provides a packaging bag, such as Figure 1-3 As shown in any one, it includes: a body 1 with a pocket 2 on it, and at least one set of bending parts 3 are arranged on the body 1 below the pocket 2. In this embodiment, the bending parts 3 can be It can be set as one set or multiple sets. When there are multiple sets of bent parts 3, the multiple sets of bent parts 3 can be arranged parallel to each other or non-parallel. The closed rib 4 is arranged on the body 1 at a position corresponding to the bent portion 3 , and the plasticity of the closed rib 4 is stronger than that of the bent portion 3 .

[0031] In the process of bearing the external force, the material will inevitably be deformed. After the external force is removed, the geometric shape of the material can only be partially restored, and a part of the deformation that cannot be recovered remains. This property of the material is called plasticity. Since the plasticity of the closed rib 4 is ...

Embodiment 2

[0039] This embodiment is made on the basis of Embodiment 1. In this embodiment, a flange 5 is provided on the body 1, such as figure 1 As shown, at least a part of the closing rib 4 is arranged on the flange 5 . At the same time, the closing rib 4 is arranged on the flange 5 and has the same length as the flange 5 .

[0040] By arranging the closing rib 4 on the flange 5, the position of the flange 5 can be fully utilized. In addition, the flange 5 and the bending portion 3 will be bent synchronously. By disposing the closing rib 4 on the flange 5, the closing action of the bag opening 2 can be realized.

[0041] Meanwhile, for the bending part 3 , usually multiple sets are arranged on the body 1 , so as to fully play the role of sealing. At this time, by arranging the closing ribs 4 and the flanges 5 at equal lengths, the closing ribs 4 can fully act on multiple groups of bending parts 3 , thereby improving the sealing performance of the bag opening 2 after being closed. ...

Embodiment 3

[0043] This embodiment is made on the basis of Embodiment 1. In the packaging bag provided by this embodiment, the closing rib 4 is arranged vertically to the height direction of the main body 1 .

[0044] In this embodiment, the closing ribs 4 act directly on the position of the bending part 3 in a horizontal state, which is different from the setting method in which the closing ribs 4 extend along the height direction of the body 1 in Embodiment 1. In this embodiment, the closing ribs Since the contact surface between the bar 4 and the body 1 is relatively small, it is easy to warp after the bending action is completed.

Abstract

The invention provides a packaging bag, which includes a main body, and a closed rib, wherein a bag opening is arranged on the main body; a bending part is arranged on the main body and positioned below the bag opening; the closed rib is arranged at the part, corresponding to the bending part, on the main body; the plasticity of the closed rib is stronger than that of the bending part. The plasticity of the closed rib is stronger than that of the bending part, so that when the bending part is bent under exogenic action, the bending part is self kept in a closing state by the closed rib due tolimitation of the closed rib, and opening is avoided.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to a packaging bag capable of sealing the mouth of the bag. Background technique [0002] Packaging bags are very common items in people's daily life, and people often use packaging bags to hold items. In the prior art, packaging bags are usually used to hold items such as tea leaves and dried fruits. For this type of article, since it is easily affected by moisture, people need to seal the mouth of the packaging bag after each tea or dried fruit is taken, so as to avoid the deterioration of the food materials inside the packaging bag. [0003] For the packaging bags in the prior art, people usually use external tools such as clips for sealing. The external clips may not be easy to obtain at any time, and they are easy to be lost after use, causing inconvenience to users. Contents of the invention [0004] Therefore, the technical problem to be solved by the present inven...
