Description

Technical Field

[0001] This utility model relates to the field of self-standing zipper bag technology, specifically a self-standing zipper bag and its reinforcing structure. Background Technology

[0002] Stand-up zipper bags are a common form of packaging widely used in the market for various commodities. They are popular with consumers because they are easy to carry and can be resealed. They are suitable for stand-up zipper packaging of food, daily necessities and other products, especially in scenarios where convenient opening and closing and standing display are required.

[0003] For example, Chinese patent CN221139290U discloses a leak-proof stand-up zipper bag, including a bag body for loading goods and a zipper for sealing the bag. The front of the bag body is rectangular and is made of non-woven fabric. The zipper bag itself is formed by sequentially stacking a first film layer, a moisture-proof layer, a non-woven fabric layer, and a second film layer. The first and second film layers provide waterproofing for both the inside and outside of the bag. The bag body has a moisture-proof layer to prevent the bag body from being damaged by moisture in humid environments. The non-woven fabric layer of the bag body uses numerous orderly arranged protrusions on the B-side layer to be embedded in numerous orderly grooves on the A-side layer, achieving a firm bond between the B-side layer and the A-side layer. The sturdy structure of the zipper bag makes it less prone to deformation even when carrying more goods. Furthermore, the moisture-proof layer and the first and second film layers make the zipper bag sturdy, moisture-proof, and waterproof, preventing product leakage.

[0004] Existing technologies for improving the performance of stand-up zipper bags involve increasing material thickness or changing material types to enhance their load-bearing capacity. However, this leads to increased costs, material waste, and more complex production processes, ultimately reducing their practicality. Utility Model Content

[0011] Furthermore, both of the aforementioned wavy ridges are provided on the front of the bag body, and both of the aforementioned wavy ridges are located on the upper and lower sides of the zipper body. At least two of the aforementioned grooves are provided at the crests and troughs on the front of the upper and lower wavy ridges.

[0012] By adopting this technical solution, the groove matches the teeth of the zipper body.

[0013] Furthermore, the front and back of the handle are both fixed with a second reinforcing rib by adhesive.

[0014] By adopting this technical solution, the sturdiness of the handle can be improved by the second reinforcing ribs on the front and rear sides. Both the handle and the second reinforcing ribs are made of the same material as the bag body, which is a flexible material.

[0015] Furthermore, at least two of the support strips are evenly distributed on the lower surface of the bag.

[0016] By adopting this technical solution, the upright stability of the bag is significantly enhanced through at least two support strips, allowing the stand-up zipper bag to stand upright without tipping over, making it convenient for users to access their items.

[0017] Furthermore, the support strip is a plastic strip, and the first reinforcing rib is a plastic rib.

[0018] By adopting this technical solution, a self-standing zipper bag can be supported and placed using no fewer than two support strips.

[0019] Furthermore, the dotted blocks are plastic blocks, and at least two of the dotted blocks are evenly distributed on the left and right sides of the bag.

[0020] By adopting this technical solution, a firm connection between the first reinforcing rib and the bag body is ensured by using no fewer than two dot-shaped blocks.

[0021] Furthermore, the wavy ridge is a rubber ridge, and the wavy ridge is located on the longitudinal central axis of the bag body.

[0022] By adopting this technical solution, the wavy convex strips on the top and bottom sides make the zipper body smoother and more durable when opening and closing.

[0023] This utility model also proposes a self-standing zipper bag, including a garbage bag body and the aforementioned reinforcing structure of the self-standing zipper bag, wherein the reinforcing structure of the self-standing zipper bag is disposed on the garbage bag body.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] This self-standing zipper bag and its reinforcing structure are made of flexible material and have a front wall, a back wall, two side walls, and a bottom. By incorporating at least two reinforcing ribs on the front and back sides of the bag, the load-bearing capacity of the self-standing zipper bag is significantly improved, enhancing its structural stability and effectively preventing deformation or damage under stress. Furthermore, by incorporating at least two support strips on the lower surface of the bag, the upright stability of the bag is significantly enhanced, allowing it to stand upright without tipping over, facilitating the user's access to items. Multiple support strips are also provided on the lower surface of the support strips. The raised sections increase friction with the contact surface when the bag stands upright, further improving its stability. At least two dotted blocks on the left and right sides of the bag ensure a secure connection between the first reinforcing rib and the bag body. Wavy raised strips on the upper and lower sides of the zipper body make the zipper smoother and more durable during opening and closing, greatly improving the user experience.
