Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging bags, in particular to a self-standing packaging bag. Background Art
[0002] Packaging bags refer to bags used to package various foods, which make it easier to transport goods during the production and circulation process and to store food.
[0003] At present, in order to prevent the packaging bag from tipping over easily and causing the food inside the packaging bag to fall out, the packaging bag with a larger bottom area is designed so that it can stand on a table or the like to prevent the packaging bag from tipping over easily;
[0004] However, during the use of the self-supporting packaging bag, as the food inside the packaging bag gradually decreases, the packaging bag will shrink and fold due to self-stress without the support of the food, so that the bottom area of the packaging bag is reduced, resulting in reduced stability of the self-supporting packaging bag. In addition, the packaging bag with more food inside will be stretched out by the food and difficult to fold. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a self-standing packaging bag, which solves the problem that as the food inside the packaging bag gradually decreases, the packaging bag will shrink and fold due to self-stress without the support of the food, so that the bottom area of the packaging bag is reduced, resulting in reduced stability of the self-standing packaging bag and the packaging bag with a lot of food inside will be stretched out by the food and difficult to fold.
[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a self-standing packaging bag, comprising a packaging bag body and a bag sealing opening arranged at the top of the packaging bag body, a first convex self-sealing strip and a first concave self-sealing strip are fixedly installed at the front and rear parts of the inner part of the bag sealing opening respectively, a bottom folding portion is arranged at the bottom of the packaging bag body, and folding strips are connected to both sides of the bottom folding portion.
[0007] Preferably, rubber pads are fixedly mounted on the front and rear ends of the bottom folding portion.
[0008] Preferably, side folding portions are provided on both sides of the packaging bag body.
[0009] Preferably, the front portion and the rear portion of one side of the side folding portion are respectively fixedly connected with a second convex self-sealing strip and a second concave self-sealing strip.
[0010] Beneficial Effects
[0011] The utility model provides a self-standing packaging bag. Compared with the existing technology, it has the following beneficial effects:
[0012] (1) The utility model pulls the front and rear sides of the packaging bag body to pull the front and rear ends of the bottom folding portion, thereby pulling the two folding strips open, so that the two folding strips support and open the bottom folding portion, thereby well supporting the bottom surface of the packaging bag body and keeping it in the largest state, effectively preventing the bottom folding portion from shrinking and folding as the amount of food inside the packaging bag body decreases, thereby ensuring the self-supporting stability of the packaging bag body.
[0013] (2) The utility model folds the side folding portion by squeezing the front and rear surfaces of the packaging bag body, and combines the second convex self-sealing strip and the second concave self-sealing strip on the side folding portion, so that the packaging bag body can be well folded and the space occupied by the packaging bag body can be effectively reduced.

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] See also Figure 1-4 The utility model provides a technical solution: a self-standing packaging bag, comprising a packaging bag body 1 and a sealing bag opening 2 arranged at the top of the packaging bag body 1. As a detailed description, the sealing bag opening 2 and the packaging bag body 1 are integrally die-cast, and the front and rear parts of the sealing bag opening 2 are respectively fixedly installed with a first convex self-sealing strip 3 and a first concave self-sealing strip 5. The bottom of the packaging bag body 1 is provided with a bottom folding portion 4, and both sides of the bottom folding portion 4 are connected to folding strips 6. As a detailed description, the folding strip 6 is a steel wire, which can be arbitrarily bent at a certain angle and maintained, and the bottom folding portion 4 is heat-sealed with a wrapping cloth that matches the folding strip 6.
[0021] Furthermore, in order to increase the friction between the packaging bag body 1 and the desktop, rubber pads 7 are fixedly mounted on the front and rear ends of the bottom folding portion 4 .
[0022] It should be noted that the rubber pad 7 improves the self-standing stability of the packaging bag body 1 , and the friction of the rubber pad 7 on the tabletop can better slow down the automatic shrinkage and folding of the packaging bag body 1 .
[0023] Furthermore, in order to fold the packaging bag body 1, side folding parts 8 are provided on both sides of the packaging bag body 1, and the front and rear parts of one side of the side folding part 8 are fixedly connected with a second convex self-sealing strip 9 and a second concave self-sealing strip 10 respectively.
[0024] When in use, the front and rear sides of the packaging bag body 1 are pulled forward and backward respectively to open the folding strips 6, so that the packaging bag body 1 is opened and propped up, and the packaging bag body 1 can be placed on the table through the friction between the rubber pad 7 and the table. When the packaging bag body 1 needs to be folded, the two folding strips 6 are folded by pressing the front and rear sides of the packaging bag body 1, so that the front and rear sides of the side folding part 8 on the packaging bag body 1 are close to each other, and then the second convex self-sealing strip 9 and the second concave self-sealing strip 10 are merged together, and at the same time, the first convex self-sealing strip 3 in the sealing bag opening 2 is merged with the first concave self-sealing strip 5 to cover the packaging bag body 1.
