Description

Technical Field

[0001] This utility model relates to the field of PE bag technology, and in particular to a product packaging PE bag component. Background Technology

[0002] PE bags, or polyethylene bags, are bags made of polyethylene plastic. They are characterized by their flexibility, good transparency, strong tear resistance, moisture resistance, and non-toxicity, and are commonly used for packaging various types of products such as food, cosmetics, and daily necessities.

[0003] A Chinese patent publication number (CN214691035U) for an anti-mold PE bag was found, comprising a PE bag body, a printing layer, and an anti-mold layer A. The printing layer is located on the outer surface of the PE bag body, and the anti-mold layer A is located on the surface of the printing layer, with the area of ​​the anti-mold layer A being approximately equal to the area of ​​the outer surface of the PE bag body. The technical solution of this utility model allows the anti-mold layer A to effectively interfere with and disrupt the physiological, biochemical reactions, and metabolic activities related to mold cells on the bag surface, thereby killing the mold and achieving an anti-mold effect. It will not easily mold even in humid weather, ensuring product quality for manufacturers. Furthermore, consumers can reuse the bag after purchasing goods. Additionally, text or patterns can be printed on the printing layer according to customer needs.

[0004] This patented technology has the advantage of being mildew-proof, but it still has shortcomings in use. Due to the inherent limitations of PE bags, they cannot be placed stably upright when storing items, making it inconvenient to store and retrieve items. There is also the problem of the PE bag tipping over and spilling its contents. To address these issues, we propose a product packaging PE bag component. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background art by proposing a product packaging PE bag assembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a product packaging PE bag assembly, including a PE self-sealing bag, a support rod one, and a support rod two. The lower end of the PE self-sealing bag is provided with a base. Support rod one and support rod two are provided on both sides inside the base. One end of support rod one is provided with a mounting block one, and one end of support rod two is provided with symmetrically distributed mounting blocks two. One end of mounting block one is provided with a rotating shaft rotatably installed inside mounting block two. A torsion spring is sleeved on the outside of the rotating shaft, with both ends connected to mounting block one and mounting block two respectively.

[0007] Preferably, the PE self-sealing bag has a bag opening at its upper end. The bag opening is the opening for storing and retrieving materials from the PE self-sealing bag.

[0008] Preferably, a sub-self-sealing strip is provided on the inner wall of one side of the bag opening, and a female self-sealing strip is provided on the inner wall of the same side of the bag opening, with the sub-self-sealing strip and the female self-sealing strip interlocking with each other. The bag opening of the PE self-sealing bag is installed by the interlocking of the sub-self-sealing strip and the female self-sealing strip, achieving a snap-fit ​​and fitting of the bag opening.

[0009] Preferably, the PE self-sealing bag has pull cords at both the front and rear ends, located on the outside of the bag opening. Users can easily lift the PE self-sealing bag by gripping the pull cords.

[0010] Preferably, the PE self-sealing bag has equidistant reinforcing ribs at both ends. These ribs enhance the strength of the PE self-sealing bag when placed upright.

[0011] Preferably, the PE self-sealing bag has side folds at both ends, the base has tapered folds at both ends, and the PE self-sealing bag has a bottom fold on its lower inner wall. The side folds provide for folding the PE self-sealing bag, the tapered folds facilitate folding at the bottom of the base, and the bottom folds facilitate folding at the bottom of the PE self-sealing bag.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a rotating support rod 1 and a support rod 2 at the bottom corner of the PE self-sealing bag. The rotating shaft between the support rod 1 and the support rod 2 is torsional elastically supported by a torsion spring. Under the elastic force of the torsion spring, the support rod 1 and the support rod 2 rotate to a specific angle and remain stable, supporting the bottom sides of the PE self-sealing bag and improving the bottom strength of the PE self-sealing bag. During use, the PE self-sealing bag can be placed vertically, which is convenient for storing and retrieving items and reduces the risk of the PE self-sealing bag tipping over.

[0020] 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.

[0021] like Figures 1-5 As shown, the present invention proposes a product packaging PE bag assembly, including a PE self-sealing bag 1, a support rod 6 and a support rod 7. The PE self-sealing bag 1 is provided with a base 9 at its lower end. The support rod 6 and the support rod 7 are provided on both sides inside the base 9. One end of the support rod 6 is provided with a mounting block 10, and one end of the support rod 7 is provided with symmetrically distributed mounting blocks 12. One end of the mounting block 10 is provided with a rotating shaft 11 that is rotatably installed inside the mounting block 12. A torsion spring 13 is sleeved on the outside of the rotating shaft 11, with both ends connected to the mounting blocks 10 and 12 respectively.

[0022] The PE self-sealing bag 1 has drawstrings 14 located on the outside of the bag opening 8 at both the front and rear ends;

[0023] Based on the implementation steps of Example 1: The PE self-sealing bag 1 needs to be placed vertically. When storing or retrieving items inside the PE self-sealing bag 1, the support rod 6 and support rod 7 inside the base 9 rotate through the pivot 11. During the rotation, a compressive force is applied to the torsion spring 13. When the support rod 6 and support rod 7 are aligned, the torsion spring 13 is twisted, and the support rod 6 and support rod 7 are supported by the bottom of the base 9. Because the bottom of the base 9 is aligned at this time, the rotation of the pivot 11 is avoided due to the limiting of the support rod 6 and support rod 7, allowing the base 9 to unfold and the bottom of the base 9 to be stable. The bag opening 8 is open, facilitating the storage and retrieval of items. At the item storage and retrieval opening, the sub-self-sealing strip 16 and the mother self-sealing strip 15 are engaged together, realizing the self-sealing of the bag opening 8 and preventing leakage of items. During use, the PE self-sealing bag 1 facilitates the storage and retrieval of items and reduces the risk of the PE self-sealing bag 1 tipping over when storing or retrieving items.

[0024] like Figures 1-5 As shown, compared with Embodiment 1, the product packaging PE bag assembly proposed in this utility model further includes: a bag opening 8 provided at the upper end of the PE self-sealing bag 1;

[0025] A sub-self-sealing strip 16 is provided on one side of the inner wall of the bag opening 8, and a female self-sealing strip 15 is provided on one side of the inner wall of the bag opening 8. The sub-self-sealing strip 16 and the female self-sealing strip 15 are interlocked with each other.

[0026] The PE self-sealing bag 1 has equidistantly distributed reinforcing ribs 2 at both the front and rear ends;

[0027] The PE self-sealing bag 1 has side folds 3 at both ends, the base 9 has tapered folds 4 at both ends, and the bottom inner wall of the PE self-sealing bag 1 has bottom folds 5.

[0028] In this embodiment, when the PE self-sealing bag 1 is stored or retrieved, the first support rod 6 and the second support rod 7 can rotate in opposite directions through the pivot 11. When an upward force is applied to the pivot 11, after the pivot 11 rotates, the elasticity of the torsion spring 13 causes the first support rod 6 and the second support rod 7 to fold. The PE self-sealing bag 1 is folded through the side folding angle 3, the tapered folding angle 4 and the bottom folding angle 5. At this time, the first support rod 6 and the second support rod 7 are close together, which facilitates the storage of the first support rod 6 and the second support rod 7. The PE self-sealing bag 1 can be folded, which facilitates the storage of the PE self-sealing bag 1 after use.

[0029] The inner wall of the self-sealing bag opening 8 features a mating strip structure consisting of a female self-sealing strip 16 and a female self-sealing strip 15. These strip structures are typically made of soft plastic material with a certain degree of elasticity. Their surfaces may have minute uneven textures that allow them to interlock when pressed. When the user presses the bag opening 8 together, the surfaces of the two self-sealing strips come into close contact, forming a sealed closure. Due to the elasticity of the material and the design of the uneven texture, this contact effectively prevents the entry of air and moisture, thus keeping the contents of the bag fresh and dry. The design of the self-sealing strips allows the two sides of the bag opening 8 to fit tightly together when pressed, forming a closed space. Even if there is a certain pressure inside the PE self-sealing bag 1, such as gas or liquid, the self-sealing strips can maintain a sealed state and prevent leakage. The structure of the self-sealing strips allows users to open and close the PE self-sealing bag 1 multiple times without affecting its sealing performance. This design makes self-sealing bags ideal for storing and protecting various items, such as food, stationery, and medicine, not only providing convenience for users but also ensuring the safety and freshness of the contents.

[0030] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
