Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of packaging bags, specifically to a multifunctional food packaging bag. Background Technology
[0002] Existing food packaging bags are mainly sealed to preserve food freshness, such as packaging bags for sunflower seeds and snacks with shells. Since sunflower seeds, peanuts (with shells), etc. are easily affected by moisture, the packaging bags are designed to be sealed. Although they can be sealed, users may forget to close the opening of the packaging bag. Some packaging bags do not have the function of resealing the opening, so once opened, they are difficult to seal.
[0003] The main problem with resealable packaging bags is that users often forget to close the opening or whether the opening is closed correctly. This is especially true for some elderly people or those with presbyopia, who may have difficulty distinguishing whether the packaging bag opening is completely sealed, often resulting in a "false" seal, which allows the food inside to become damp.
[0004] Secondly, when consumers use snacks, especially sunflower seeds and peanuts, they generate shells. At this time, consumers hold the food packaging bag while the shells need to be thrown into the trash can. This usage method brings inconvenience to users, as they have to repeatedly throw away the trash from a distance every time shells are generated, which is not a good user experience.
[0005] Some users even put fruit peels together with garbage bags, but this results in uneaten fruit being mixed with the peels, which is unhygienic. Utility Model Content
[0006] To address the technical problems and shortcomings of existing technologies, this invention provides a multi-functional food packaging bag with multiple storage spaces, facilitating the storage of fruit peels and other waste. Its resealable design provides reliable food preservation and prevents food from becoming damp.
[0007] To achieve the above and other related objectives, the present invention adopts the following technical solution:
[0008] A multifunctional food packaging bag includes at least two nested main bag bodies. A moisture-proof sheet is fixed inside each main bag body. The main bag bodies have an opening and a folded bottom. The two nested main bag bodies are separated by a tear line with pre-set slits. The main bag bodies have multiple sealing structures.
[0009] The multiple sealing structure includes a magnetic sealing strip and a snap-on sealing strip. The snap-on sealing strip is located below the magnetic sealing strip. The snap-on sealing strip includes a female snap-on strip and a male snap-on strip. The female snap-on strip includes an upper snap-on edge and a lower snap-on edge. An easy-open gap is left on the upper snap-on edge.
[0010] Preferably, the hardness of the lower buckle edge is greater than that of the upper buckle edge, or the thickness of the lower buckle edge is greater than that of the upper buckle edge.
[0011] Preferably, the male and female fasteners are respectively provided with mutually cooperating positioning structures, the positioning structures including positioning protrusions and positioning grooves, and the positioning structures are located below the magnetic sealing strip.
[0012] Preferably, a secondary bag identical to the main bag body is provided on one side of the main bag body, the upper ends of the main bag body and the upper ends of the secondary bag body are fixed together by heat fusion, and the bottom of the main bag body and the bottom of the secondary bag body are fixed together by heat fusion.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model adopts a two-layer stacked design for the main bag body, which allows users to expand one bag body into multiple bags according to their needs. This makes it convenient for users to put sunflower seeds, peanuts, or fruit shells, etc., and is easy to use. At the same time, the multi-layer sealing structure improves the reliability of the sealing operation, making it easier to seal and less likely to cause false seals compared to traditional sealing operations.
[0015] 2. To ensure reliable sealing, this design utilizes different hardness or thickness of the upper and lower clips to alter the force applied to the clips, making it more difficult to open the sealing strip from the inside and easier from the outside.
[0016] 3. To reduce the occurrence of false seals, a magnetic sealing strip is used to assist in alignment, and positioning is further achieved through positioning protrusions and positioning grooves, thereby ensuring accurate positioning when the male and female fasteners are assembled.
[0017] 4. To further enhance users' spatial classification needs for the bags, the system has been expanded to include four bag compartments for storing items.
[0018] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0030] Example 1:
[0031] This invention discloses a multifunctional food packaging bag, as per embodiments. Figure 1 , Figure 2 and Figure 3 As shown, the main bag body 1 comprises at least two nested layers. This design preferably uses two nested layers, referred to as the inner bag body and the outer bag body for ease of description. The inner and outer bag bodies can be made of the same material or other composite materials. In a specific example, kraft paper is used to make both the inner and outer bag bodies.
[0032] exist Figure 1 As can be seen, a moisture-proof sheet 2 is fixed inside the main bag body 1. The moisture-proof sheet 2 is made of water-absorbing or moisture-absorbing material, which can extend the moisture-proof time of food. The food moisture-proof sheet 2 is mainly used in food packaging to prevent food from getting damp and moldy by absorbing moisture, thus ensuring quality. For example, in this specific example, fiber desiccants or mineral desiccants are used. The moisture-proof sheet 2 can be fixed by adhesive.
[0033] exist Figure 3 As can be seen, the main bag 1 has an opening 11 and a folded bottom 12. To further improve the user's spatial classification needs, it can be expanded to provide storage space for four bags. A secondary bag 6 identical to the main bag 1 is provided on one side. The upper ends of the main bag 1 and the secondary bag 6 are fixed together by heat fusion. The bottom 12 of the main bag 1 and the bottom 12 of the secondary bag 6 are also fixed together by heat fusion.
[0034] exist Figure 2As understood, two nested main bag bodies 1 are separated by a tear line 3. A pre-cut slit 4 is provided at the location of the tear line 3. Multiple sealing structures 5 are provided inside the main bag body 1. The tear line 3 is stronger than the bag body, and the pre-cut slit 4 makes it easier to tear off the tear line 3, thereby opening the closed (bag body) opening 11.
[0035] It should be noted that the bag opening can be left open when the food is not packed. After the food is packed, the bag opening is generally sealed by heat sealing, for example... Figure 2 The outer edge of the bag shown is sealed by heat pressing. This seal can be removed by tearing the tear line 3 or by tearing through the pre-set cut 4, thus opening the bag. After opening the bag, the inner and outer bag layers can be separated.
[0036] Combination Figure 4 As shown, the multi-seal structure 5 includes a magnetic sealing strip 51 and a snap-on sealing strip 52, with the snap-on sealing strip 52 located below the magnetic sealing strip 51. The snap-on sealing strip 52 includes a sub-strip 521 and a female strip 522, with the female strip 522 including an upper snap edge 524 and a lower snap edge 525, and the upper snap edge 524 having an easy-open gap 523.
[0037] This solution adopts a two-layer stacked design for the main bag body 1. This allows users to expand one bag body into multiple bags according to their needs, making it convenient for users to place sunflower seeds, peanuts, or fruit shells, etc. At the same time, the multi-layer sealing structure 5 improves the reliability of the sealing operation, making it easier to seal and less likely to have a "false" seal compared to traditional sealing operations.
[0038] The lower snap-on edge 525 has a higher hardness than the upper snap-on edge 524, or the lower snap-on edge 525 has a greater thickness than the upper snap-on edge 524. Increasing the thickness to improve hardness is one method, and it can also be achieved by changing the material, such as by adjusting the temperature during the molding process to create plastic materials of varying hardness. To ensure reliable sealing, compared to traditional symmetrical snap-on designs, this solution utilizes different hardnesses or thicknesses in the upper and lower snaps to alter the force applied to the snaps. This results in the inner snap-on sealing strip 52 requiring more effort to open, while the outer snap-on strip is easier to open. It should be noted that... Figure 4 The top is the outer side, making it easy to open the bag by hand through the top opening 11. The bottom of the buckle sealing strip 52 is the inner side. If air is present inside the bag, the bottom of the bag will be compressed, making it difficult to open under pressure, thus enhancing security.
[0039] Example 2:
[0040] Based on the above embodiment one, refer to Figure 5As shown, the difference lies in that the sub-snap strip 521 and the female snap strip 522 are respectively provided with mutually cooperating positioning structures 53. The positioning structure 53 includes a positioning protrusion 531 and a positioning groove 532, and the positioning structure 53 is located below the magnetic sealing strip 51.
[0041] To reduce the occurrence of "false" sealing operations, a magnetic sealing strip 51 is used to assist in alignment, and positioning is further achieved through positioning protrusions 531 and positioning grooves 532, thereby ensuring accurate positioning when the male and female locking strips 521 and 522 are assembled.
[0042] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
