Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and in particular to a packaging bag with a quick sealing function. Background Technology

[0002] Packaging bags are bags used to package various goods, facilitating transportation and storage during production and distribution. They are widely used in daily life and industrial production. Packaging bags can be classified according to their material into plastic packaging bags, paper packaging bags, and composite packaging bags. Common plastic packaging bags include PE bags and PP bags. PE bags have good moisture resistance and low transparency, making them suitable for fresh produce. PP bags have high transparency but are easily broken, making them suitable for snacks. However, existing plastic packaging bags have significant shortcomings in sealing and structural performance, which can cause some inconvenience when using them. In practical use, existing plastic packaging bags mostly rely on snap-on sealing strips for sealing. However, this structure is easily constrained by the bag's filling state: when the bag is filled with a lot of material and the bag is bulging due to fullness, the bag opening will remain open due to internal tension. This not only makes it difficult to quickly align the snap-on structure, causing the sealing strip to fail to snap into place smoothly for a quick seal, but even if it is managed to snap in place, the continuous internal tension will cause uneven stress on the snap-on sealing strip, making it prone to loosening and misalignment. Ultimately, this leads to a significant decrease in the stability of the seal strength, making it difficult to guarantee a long-term reliable sealing effect. Therefore, we propose a packaging bag with a quick-sealing function. Utility Model Content

[0003] In view of the technical problem that the snap-on sealing strip of existing plastic packaging bags is easily restricted by the filling state of the bag, when the bag is filled with a lot of material and the bag is bulging due to fullness, the bag opening will remain open due to internal tension. This not only makes it difficult to quickly align the concave and convex structure of the snap-on, but also makes it difficult for the sealing strip to bite smoothly and complete the quick sealing. This utility model provides a packaging bag with a quick sealing function.

[0004] The technical solution adopted by this utility model is: a packaging bag with a quick-sealing function, including a packaging bag body, a sealing component and a thickened bottom pad. The sealing component includes a reinforced outer edge, an extension section, a snap-on sealing strip, a first inner cover, a second inner cover, a lifting strap, a heat-pressing block and an elastic adhesive strip. The extension section is disposed on the upper outer surface of the reinforced outer edge. The snap-on sealing strip, the first inner cover and the second inner cover are all disposed inside the extension section. The first inner cover and the second inner cover are both located below the snap-on sealing strip. The first inner cover is located on one side of the second inner cover. The lifting strap is disposed above the extension section. The heat-pressing block is disposed between the lifting strap and the reinforced outer edge. The elastic adhesive strip is disposed inside the lifting strap.

[0005] Furthermore, the thickened base pad has a reinforcing strip and an air bladder inside, with the reinforcing strip located above the air bladder.

[0006] Furthermore, the reinforced outer edge and the extension section are integrally formed, the length of the first inner cover is 3.5 cm, and the length of the second inner cover is 5 cm.

[0007] Furthermore, the lifting band and the elastic strip are integrally formed, and the lifting band is fixedly connected to the reinforced outer edge through the hot pressing block.

[0008] Furthermore, the reinforcing strip has a cross-shaped structure, and the airbag has a width of 2.5 cm.

[0009] Furthermore, the upper outer surface of the thickened base pad is fixedly connected to the lower outer surface of the packaging bag body, and the inner wall of the reinforced outer edge is fixedly connected to the outer wall of the packaging bag body.

[0010] The beneficial effects of this utility model are as follows: In this utility model, the sealing component is fixed to the bag opening of the packaging bag body by reinforcing the outer edge. After the contents are filled, the second inner cover is first covered, and then the first inner cover is stacked to form a preliminary dust and moisture barrier. Then, the extension section port is sealed by snap-on sealing strip. Because the extension section is connected to the bag body by reinforcing the outer edge, even if the bag is filled with a lot, the snap-on sealing can still be guaranteed to be fast and the sealing effect can be improved.

[0015] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0016] To address the problems existing in the background art, this application proposes the following technical solution: a packaging bag with a rapid sealing function.

[0017] The specific technical solution includes a packaging bag body 1, a sealing component 2, and a thickened bottom pad 3. The sealing component 2 includes a reinforced outer edge 201, an extension section 202, a snap-on sealing strip 203, a first inner cover 204, a second inner cover 205, a lifting strap 206, a heat-pressing block 207, and an elastic strip 208. The extension section 202 is located on the upper outer surface of the reinforced outer edge 201. The snap-on sealing strip 203, the first inner cover 204, and the second inner cover 205 are all located inside the extension section 202. The first inner cover 204 and the second inner cover 205 are both located below the snap-on sealing strip 203, with the first inner cover 204 located to one side of the second inner cover 205. The lifting strap 206 is located above the extension section 202. The heat-pressing block 207 is located between the lifting strap 206 and the reinforced outer edge 201. Between the outer edges 201, the elastic strip 208 is set inside the lifting strap 206. When in use, the sealing component 2 can be fixed to the bag opening of the packaging bag body 1 by reinforcing the outer edges 201. After the packaging bag body 1 is filled with items, the second inner cover 205 can be covered first, and then the first inner cover 204 can be covered on the second inner cover 205, so that the first inner cover 204 and the second inner cover 205 form an initial barrier against dust and moisture. Then, the extension section 202 port is locked and sealed by the snap-on sealing strip 203. Since the extension section 202 is connected to the packaging bag body 1 by reinforcing the outer edges 201, when the packaging bag body 1 is loaded with more items, the extension section 202 can still ensure that the snap-on sealing strip 203 can quickly lock and seal, which can improve the sealing effect.

[0018] Furthermore, the reinforced outer edge 201 and the extension section 202 are integrally formed structures. The length of the first inner cover 204 is 3.5CM, and the length of the second inner cover 205 is 5CM. The first inner cover 204 and the second inner cover 205 can initially block dust and moisture from entering, thereby improving the sealing effect of the packaging bag body 1.

[0019] Furthermore, the lifting strap 206 and the elastic strip 208 are integrally molded. The lifting strap 206 is fixedly connected to the reinforced outer edge 201 through the hot pressing block 207. The lifting strap 206 can easily lift the packaging bag body 1 for easy carrying.

[0020] Furthermore, the upper outer surface of the thickened base pad 3 is fixedly connected to the lower outer surface of the packaging bag body 1, and the inner wall of the reinforced outer edge 201 is fixedly connected to the outer wall of the packaging bag body 1. The thickened base pad 3 mainly protects the bottom of the thickened base pad 3 and can improve wear resistance.

[0021] Reference Figure 4 As shown, the thickened base pad 3 has a reinforcing strip 4 and an air bladder 5 inside. The reinforcing strip 4 is located above the air bladder 5. When in use, the thickened base pad 3 can improve the load-bearing capacity of the packaging bag body 1 through the internal reinforcing strip 4, and the internal air bladder 5 can play a role in resisting pressure. When loading items, the thickened base pad 3 can provide stable support and prevent the bottom of the bag from being deformed or broken due to the pressure of heavy objects. At the same time, it is convenient to place the packaging bag upright and improve the convenience of loading.

[0022] Furthermore, the reinforcing strip 4 has a cross-shaped structure, and the airbag 5 is 2.5 cm wide. The reinforcing strip 4 mainly serves to resist pressure and tension.

[0023] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: When in use, the reinforcing outer edge 201 is fixed to the opening of the packaging bag body 1. After the packaging bag body 1 is filled with items, the second inner cover 205 can be covered first, and then the first inner cover 204 can be placed on top of the second inner cover 205. This allows the first inner cover 204 and the second inner cover 205 to initially block dust and moisture from entering. Then, the extension section 202 is sealed by the snap-on sealing strip 203. Since the extension section 202 is connected to the packaging bag body 1 through the reinforcing outer edge 201, the extension section 202 can still ensure that the snap-on sealing strip 203 can quickly lock and seal even when the packaging bag body 1 is loaded with a large number of items. This design improves the sealing effect, and the packaging bag body 1 can be lifted by the lifting strap 206 during use for easy carrying. The lifting strap 206 is fixed to the reinforced outer edge 201 by the heat-pressing block 207, which can improve the strength of use. The elastic rubber strip 208 inside the lifting strap 206 can improve its tensile strength. The thickened bottom pad 3 can improve the load-bearing capacity of the packaging bag body 1 through the internal reinforcing rubber strip 4 during use, and the internal air bladder 5 can play a role in resisting pressure. When loading items, the thickened bottom pad 3 can provide stable support and prevent the bottom of the bag from being deformed or broken due to the pressure of heavy objects. At the same time, it can facilitate the upright placement of the packaging bag and improve loading convenience.
