Description

Technical Field

[0001] The present application relates to the technical field of packaging bags, and in particular to a packaging bag. Background Art

[0002] Ziplock bags are self-sealing bags that do not require any tools to seal. They can be used to store various small parts (such as nuts, nails, etc.) and play an anti-corrosion role. Ziplock bags made of food-grade raw materials can be used to store tea, dried fruits, rice, and frozen foods to avoid moisture absorption and odor contamination. Books and clothes can also be stored in them, and they have the advantages of moisture-proof and insect-proof. In addition, ziplock bags are widely used in laboratory sampling, sample storage, and transportation processes, making up for the shortcomings of hard containers that are heavy, take up a lot of space, are fragile, and are not easy to carry.

[0003] However, in the prior art, ziplock bags focus on the improvement of their loading and sealing functions, but often ignore whether the ziplock bags are convenient to operate during use (such as carrying, transporting, pouring out liquids, etc.) after loading objects. There is also a type of ziplock bag with a handle, whose opening position conflicts with the handle position, making it inconvenient to use, and the handle position is relatively thin, which is easy to strangle or break. Therefore, there is room for improvement. Summary of the invention

[0004] In view of the above problems, the present application proposes a packaging bag, which is provided with a stronger reinforced handle portion on the packaging bag, and the handle position is staggered with the opening position of the packaging bag, so as to achieve the actual effect that the packaging bag with a heavier weight is still stable, convenient to carry without affecting storage and retrieval, and not easy to be pinched and broken; the packaging bag is specifically realized by the following technical solutions:

[0005] A packaging bag comprises a hollow bag body, on which at least two layers of extension sheets are stacked and arranged, the at least two layers of extension sheets are connected together to form a reinforced hand-held portion, the reinforced hand-held portion is provided with a hand-held opening, and the at least two layers of extension sheets are fixedly connected.

[0006] It is further configured that the bag body includes a first bag sheet and a second bag sheet, the first bag sheet and the second bag sheet overlap each other and are fixedly connected on all sides by heat sealing, and then the second bag sheet is cut to form the extension sheet and the opening of the bag body. Through this configuration, the first bag sheet and the second bag sheet together constitute the bag body, which is more stable.

[0007] It is further arranged that the inner wall of the opening formed by cutting the bag body is provided with a sealing device, and through this arrangement, the opening is sealed to improve the sealing performance of the packaging bag.

[0008] Further configuration includes a bottom plate, the outer edges of the bottom plate are respectively heat-sealed to the first bag sheet and the second bag sheet to form a first arcuate heat-sealed edge and a second arcuate heat-sealed edge, a connection point is provided between the first arcuate heat-sealed edge and the second arcuate heat-sealed edge by heat sealing, the bottom plate, the first arcuate heat-sealed edge and the second arcuate heat-sealed edge together form a base that can be placed stably, through this configuration, the packaging bag can be placed stably on a plane for easy transportation.

[0009] A further configuration is provided, comprising a protective ring, the protective ring comprising a male ring and a female ring, the male ring being provided with a tenon, the female ring being provided with a corresponding mortise, an inner edge of the portable opening being provided with an opening corresponding to the tenon, the protective ring being assembled by passing the tenon through the opening and then inserting it into the mortise, and the protective ring clamping the extension piece. Through this configuration, the portable opening can be prevented from scratching the hands, making it safer to use.

[0010] It is further arranged that the mortise and the female ring are an integral structure, and the tenon and the male ring are an integral structure. Through this arrangement, the strength is increased and the whole is more stable.

[0011] It is further configured that the bag body is provided with a pouring device, the pouring device comprises a threaded base and a screw cap, the inner end of the threaded base is arranged on the bag body by heat sealing, and the screw cap threaded cover is arranged on the outer end of the threaded base. Through this configuration, it is convenient to pour out the liquid in the bag body, and it can also be resealed, which is more convenient to use.

[0012] It is further configured that a tear ring is sleeved on the threaded base, and when the screw cap is connected to the threaded base, the screw cap and the tear ring are integrally connected. Through this configuration, a one-time opening device is provided to prevent food safety problems caused by secondary opening.

[0013] It is further configured that the contact positions of the tear ring and the screw cap are respectively provided with toothed portions, and the toothed portions include convex portions and concave portions. When the screw cap is screwed onto the threaded base, the convex portions and concave portions in the toothed portions on the tear ring and the screw cap are staggered and tightly engaged with each other. Through this configuration, the screwing position of the screw cap is further limited, so that the sealing effect is more stable.

[0014] In summary, the packaging bag is provided with a reinforced handle on the bag body by adding multiple layers of material, so that the handle part of the entire packaging bag is stronger and tougher. When the packaging bag is full of objects, it is more stable to hold it through the handle, and the handle does not affect the use of the opening when holding. BRIEF DESCRIPTION OF THE DRAWINGS
