Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a shrinkable non-woven fabric packaging bag. Background Art

[0002] Non-woven fabric packaging bags are made of non-woven fabric (non-woven cloth) through processes such as cutting, sewing, ironing, and inspection. Non-woven fabric is a fiber product directly formed without a textile process, with the characteristics of softness, breathability, and a planar structure, and has the following characteristics: non-woven fabric packaging bags are tough, durable, beautiful in shape, good in breathability, reusable, washable, and environmentally friendly and degradable. Their materials are mostly polypropylene spunbond non-woven fabric and polyester spunbond non-woven fabric, and these materials have characteristics such as moisture-proof, breathable, flexible, light in weight, non-flammable, easy to decompose, non-toxic, and non-irritating.

[0003] A patent with a publication date of June 28, 2024, and a publication number of CN221234355U discloses a moisture-proof non-woven fabric packaging bag, including a packaging bag body. Sealing layers are provided on both inner walls of the packaging bag body, and a same first zipper is provided on the two sealing layers. Four cushion blocks are fixedly connected to the bottom of the packaging bag body. In the utility model, by setting the two sealing layers to be closed through the first zipper, the packaging bag body can be sealed after placing items therein. At the same time, through the setting of the four cushion blocks, the bottom of the packaging bag body is prevented from contacting with water droplets, reducing the corrosion rate of the bottom of the packaging bag body and extending the service life of the bag body. By placing desiccants in the bag, it further plays a role in protecting the items in the packaging bag body, preventing the items from deteriorating or being damaged due to excessive humidity. Through the composite moisture-proof mold layer composed of the first moisture-proof layer, the second moisture-proof layer, and the third moisture-proof layer, it plays a role in multi-layer moisture-proofing, and the moisture-proof effect is good.

[0004] In modern society, the requirements for space utilization in logistics transportation and warehousing management are getting higher and higher. Traditional fixed-size packaging bags often occupy unnecessary space during storage and transportation. Especially when the volume of goods is smaller than the original size of the packaging bag, it will cause space waste. While shrinkable non-woven fabric packaging bags can be in a nearly flat state when not in use, greatly reducing the space required for storage. When it is necessary to load items, it can be simply stretched to return to the normal state, which is both convenient and efficient, effectively improving the space utilization rate of storage and transportation. The above scheme considers increasing the moisture-proof performance of non-woven fabric packaging bags, but does not consider the space optimization and storage convenience of non-woven fabric packaging bags.

[0005] Therefore, it is necessary to provide a shrinkable non-woven fabric packaging bag. Summary of the Utility Model

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "comprising" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0027] To address the problem that traditional non-woven fabric packaging bags with fixed sizes in related technologies often occupy unnecessary space during storage and transportation, especially when the volume of the product is smaller than the original size of the packaging bag, resulting in wasted space, the embodiments of the present application provide the following solutions.

[0028] Please refer to Figures 1-4 , including: a packaging bag body 1, a handle 2, a snap button 3, a snap base 4 and a winding roller 5. The winding roller 5 is divided into four parts, including a first sub-roller 51, a second sub-roller 52, a third sub-roller 53, and a fourth sub-roller 54. The first sub-roller 51, the second sub-roller 52, the third sub-roller 53, and the fourth sub-roller 54 are respectively bonded to the inner and outer sides of the longer sides of the bottom surface of the packaging bag body 1. The handle 2 is fixedly connected to both sides of the packaging bag body 1. The snap button 3 is fixedly connected to the handle 2. The snap base 4 is fixedly connected to both sides of one end of the packaging bag body 1 away from the winding roller 5. The first sub-roller 51 and the second sub-roller 52 are bonded to the inner side of the bottom surface of the packaging bag body 1. The third sub-roller 53 and the fourth sub-roller 54 are bonded to the outer side of the bottom surface of the packaging bag body 1. Magnetic strips 6 are bonded to the first sub-roller 51 and the third sub-roller 53. Grooves are provided in the second sub-roller 52 and the fourth sub-roller 54. The height of the magnetic strip 6 is the same as the depth of the groove, and the inside of the groove is made of magnetic material.

[0029] With such arrangement, after the packaging bag is used up, it needs to be shrunk to reduce the occupied space. The user touches the two sides of the packaging bag with the largest area with both hands and presses inward, and at the same time allows the magnetic strip 6 on the first roller 51 to enter the groove of the second roller 52. The magnetic strip 6 and the magnetic material generate and attract each other, so that the first roller 51 and the second roller 52 are merged. Similarly, the third roller 53 and the fourth roller 54 are merged. In this way, the first roller 51, the second roller 52, the third roller 53 and the fourth roller 54 are combined into a complete winding roller 5, and the winding roller 5 is rotated along the direction of flattening the packaging bag body 1. The packaging bag body 1 is wound into multiple layers on the winding roller 5, and then the handle 2 is tightened and used as a strap to circle the packaging bag body 1 wound into multiple layers, and then the snap button 3 on the handle 2 is aligned with the snap seat 4 and pressed to fix the packaging bag body 1 wound into multiple layers so that it will not loosen.

[0030] Optionally, in some embodiments, please refer to Figure 5 A waterproof layer 7 is abutted against the interior of the packaging bag body 1 .

[0031] With such arrangement, the waterproof layer 7 can effectively isolate moisture and reduce the degradation and oxidation reaction of the contents due to moisture. This is especially important for some items that need to be stored for a long time, such as electronic products, precision instruments, etc. During transportation, loading and unloading, storage, etc., the packaging bag may face various complex environmental conditions, such as humidity and rain. The waterproof layer 7 prevents these moisture from invading the interior of the packaging bag, thereby protecting the contents.

[0032] Optionally, in some embodiments, please refer to Figure 2 as well as Figure 3 , the winding roller 5 is made of carbon fiber material.

[0033] With this setting, the strength of carbon fiber is much higher than that of traditional metal materials, and the density of carbon fiber is very low, which reduces weight while maintaining high strength. Its surface is smooth and not easy to absorb moisture and pollutants. It has good corrosion resistance, which increases service life and reduces manpower.

[0034] Optionally, in some embodiments, please refer to Figure 1 The two sides of the short side of the packaging bag body 1 are fixedly connected with a net bag 8, and the net bag 8 is elastic.

[0035] With such arrangement, when there is a need to place some items that cannot be squeezed, such as eggs, or when there is a need to place some items that need to be taken out and used at hand, such as a bottle of water, these items can be placed in the net bag 8. The elastic net bag 8 expands the volume range that can be placed for items. At the same time, the elasticity of the net bag 8 gives it a certain fixing ability.

[0036] Optionally, in some embodiments, please also refer to Figure 1 A zipper 9 is fixedly connected to the open end of the packaging bag body 1. A cover cloth 11 is sewn on one side of the open end of the packaging bag body 1 away from the zipper. The cover cloth 11 closes the open end of the packaging bag body 1 through the zipper 9.

[0037] With such a setting, the design of the zipper 9 makes the opening and closing of the packaging bag very convenient. The user only needs to gently pull it to cooperate with the cover cloth 11 to open or close the bag mouth, without the need to fold, tie a knot or find other fixing methods like traditional packaging bags. For the situation of taking out items multiple times, the zipper 9 packaging bag can keep the bag mouth tight, prevent items from scattering, and at the same time facilitate the user to close the bag mouth again for repeated use. During transportation and storage, the zipper 9 packaging bag can prevent pollutants such as dust and impurities from entering the bag and keep the cleanliness of the items inside. The design of the zipper 9 can ensure that the packaging bag will not accidentally open during carrying or transportation, thus preventing the loss or theft of the items inside. This is particularly important for users who need to carry valuable items or important documents.

[0038] Optionally, in some embodiments, please also refer to Figure 2 A support rod 10 is arranged inside the packaging bag body 1. One end of the support rod 10 abuts against the first sub-roller 51, and the other end abuts against the second sub-roller 52. Chutes are provided on the third sub-roller 53 and the fourth sub-roller 54, and the support rod 10 can be taken out and slidably connected in the chutes.

[0039] With such a setting, during use, when the packaging bag body 1 is opened, the support rod 10 is taken out from the chutes provided on the third sub-roller 53 and the fourth sub-roller 54, and then the support rod 10 is placed between the first sub-roller 51 and the second sub-roller 52 to prevent the magnetic stripe 6 on the first and third sub-rollers 53 from being accidentally sucked into the grooves of the second and fourth sub-rollers 54. When the packaging bag body 1 needs to be wound up, the support rod 10 is taken out from the packaging bag body 1 and placed back into the chutes provided on the third sub-roller 53 and the fourth sub-roller 54.

[0040] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
