Description

Technical Field

[0001] This application belongs to the field of packaging bag technology, and specifically relates to a multi-chamber packaging bag. Background Technology

[0002] In the market, it is often necessary to store two different substances separately before use to avoid mutual reaction, and to mix them by opening the device when needed.

[0003] However, traditional packaging bags often require force to open by squeezing one side. If too much force is required, they may be difficult to open or impossible to open, leading to complicated operation and unsmooth opening. If too little force is required, they may be accidentally opened, causing the two substances to mix prematurely, affecting quality or taste, and greatly impacting the consumer's experience and efficiency.

[0004] Therefore, there is an urgent need to develop a technology that makes it easier to open packaging bags. Utility Model Content

[0005] To address the shortcomings of the prior art, this application provides a multi-chamber packaging bag. Through the design of the opening section, by grasping the opening section by hand and pulling it outward, the weak sealing area can be torn open, allowing for the mixing of multiple substances. The opening operation is simple and smooth, effectively improving the opening efficiency and enhancing the consumer's user experience.

[0006] The technical effects to be achieved in this application are realized through the following aspects:

[0007] This application provides a multi-chamber packaging bag, including

[0008] A bag body, including a normal heat-sealing area located around the periphery of the bag body, the normal heat-sealing area enclosing a chamber, the bag body having at least one weak-sealing area within the chamber, the weak-sealing area serving to divide the chamber into at least two relatively sealed regions; and

[0009] An opening portion is provided at least on one side of the bag body. The opening portion protrudes from the bag body and is disposed opposite to the weak sealing area, and is used to open the weak sealing area. The opening portion is formed by folding the bag body away from the chamber.

[0010] In some implementations, the opening portion is located opposite each other on both sides of the bag body.

[0011] In some implementations, the weak sealing region is a wavy weak sealing structure.

[0012] In some implementations, the weak sealing area includes a wavy weak sealing structure in the middle and strip-shaped weak sealing structures on both sides, wherein the opening threshold of the wavy weak sealing structure is less than the opening threshold of the strip-shaped weak sealing structure.

[0013] In some implementations, the weak sealing area is located on one side of the opening section, and one side is connected to the opening section.

[0014] In some implementations, the opening section includes a lifting area and a sealing area, which are relatively separated from each other.

[0015] In some implementations, the lifting area is configured to correspond to the wavy weak sealing structure, and the edge sealing area is configured to correspond to the strip weak sealing structure.

[0016] In some implementations, the bag body includes a first sheet and a second sheet, and the cavity is formed by fusing the peripheral sides of the first sheet and the second sheet together;

[0017] The first sheet and the second sheet have a tear on one side. The tear is used to tear one side of the first sheet and the second sheet to form an opening in the bag.

[0018] In some implementations, the surface of the opening portion is provided with an anti-slip layer.

[0019] In some implementations, the opening portion is provided with at least one pull hole.

[0020] In summary, this application has at least the following advantages:

[0021] The multi-chamber packaging bag provided in this application divides the chambers into at least two relatively sealed areas through a weak-seal zone, allowing for the separate loading of at least two substances. When mixing is required, the opening section is held and pulled forcefully away from the chambers, opening the weak-seal zone and reducing the number of chambers to one. Multiple substances can then be mixed by shaking, ensuring mixing quality. After mixing, the bag is opened through the tear opening to reveal the mixture inside. The overall opening operation is simple and convenient, effectively improving opening efficiency and enhancing the consumer experience. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0029] Example 1:

[0030] Please see the appendix Figure 1 The present application discloses a multi-chamber packaging bag, comprising a bag body 1 and an opening section 2.

[0031] The bag body 1 includes a normal heat-sealed area located around its perimeter, which encloses a cavity. Within this cavity, the bag body 1 has at least one weak-sealing area 12, which divides the cavity into at least two relatively sealed regions. The cavity is used to hold a substance. The weak-sealing area 12 is a small area formed by heat sealing; a force of 5-8 Newtons is sufficient to open it, allowing the divided cavities to recombine, facilitating the mixing of the substance and ensuring its quality and taste. Preferably, the weak-sealing area 12 can be positioned in the middle of the bag body 1, effectively dividing the cavity into two equal regions.

[0032] The opening section 2 is located at least on one side of the bag body 1. The opening section 2 protrudes from the bag body 1 and is positioned opposite the weak sealing area 12, used to open the weak sealing area 12. The protruding opening section 2 facilitates the user's picking up and pulling, thereby applying force to the bag body 1 and improving the ease of opening the bag. Specifically, by positioning the opening section 2 opposite the weak sealing area 12, when the user applies force to the opening section 2, the force is directly transmitted to the weak sealing area 12, reducing force loss and improving the ease of opening the weak sealing area 12, making the operation effortless and easy.

[0033] The opening section 2 is formed by folding the bag body 1 away from the cavity. Specifically, the opening section 2 and the bag body 1 are formed from the same sheet material. Folding can be achieved by extruding outwards in the direction away from the cavity, and then bringing the two sides of the extruded sheet together. Preferably, the opening section 2 protrudes outwards from the bag body 1 by 8-20mm. That is, the opening section 2 protrudes from the bag body 1 by a certain width, making it easy for the user to pick up the opening section 2 and operate it, facilitating the application of force by the user, improving the ease of opening the packaging bag, and making operation simple.

[0034] In this embodiment, the packaging bag divides the chamber into at least two relatively sealed areas via a weak-seal area 12. Corresponding substances can then be placed in the corresponding chambers. When mixing is required, the user holds the opening part 2 and pulls it away from the chamber until the weak-seal area 12 is opened, allowing multiple substances to be mixed. At this point, the bag body 1 is not yet opened, and it can be shaken thoroughly to ensure complete mixing. This design makes the overall bag opening operation simple and smooth, with high efficiency. It also reduces the possibility of accidental opening of the weak-seal area 12, preventing premature mixing and ensuring the quality of the mixture, thereby improving the user experience.

[0035] In this structure, the opening part 2 and the bag body 1 are integrated, which improves the transmission of force and the continuity during the pulling process. It is also easier and more convenient to tear open the weak sealing area 12. That is, when opening, you can grab the protruding opening part 2 with your hand and pull it outward with force to open the weak sealing area 12 in the middle.

[0036] Furthermore, compared to designs where the opening section 2 and the bag body 1 are not integrated, the opening section 2, which is integrated with the bag body 1, is more robust and less prone to detachment or tearing, thus ensuring the stability of the opening section 2.

[0037] In addition, when the opening part 2 of the packaging bag is designed to be integrated with the bag body 1, the overall production process can reduce the corresponding production steps and effectively reduce production costs.

[0038] In some embodiments, the opening portion 2 is disposed opposite to each other on both sides of the bag body 1. By providing the opening portion 2 on both sides of the bag body 1, during the opening process, the user can use their hands to apply force to the opening portion 2 on both sides of the bag body 1 and simultaneously move away from the cavity to open the weak sealing area 12. This arrangement can enhance the force applied to the weak sealing area 12, making it easy to open. The operation is easy and quick, and the force is evenly applied, ensuring the quality of opening the bag.

[0039] In some embodiments, the weak sealing area 12 is a wavy weak sealing structure. Specifically, the adhesive area of ​​the wavy weak sealing structure is small, so the adhesive force is not very large, thereby avoiding the phenomenon that the weak sealing area 12 is difficult to tear off, effectively reducing the adhesive strength, and realizing the ease of tearing off the weak sealing area 12.

[0040] In some embodiments, the weak-seal area 12 includes a wavy weak-seal structure in the middle and strip-shaped weak-seal structures on both sides. The tear-open threshold of the wavy weak-seal structure is lower than that of the strip-shaped weak-seal structure. This arrangement allows the wavy weak-seal structure to correspond to the opening section 2, facilitating the user to tear the bag starting from the wavy weak-seal structure. The weak adhesive strength of this structure improves the ease and convenience of tearing. During the tearing process, the tear extends from the wavy weak-seal structure to the strip-shaped weak-seal structure until the bag is completely torn. This structure not only improves the ease and convenience of tearing the bag but also ensures the stability of the weak-seal area 12, preventing accidental opening and premature mixing of the material, thus ensuring the stability of the weak-seal area 12.

[0041] In some embodiments, the weak sealing area 12 is located on one side of the opening portion 2, and one side is connected to the opening portion 2. With this arrangement, during the tearing process, the opening portion 2 preferentially applies force to the weak edge of the weak sealing area 12, making it easier to open the weak sealing area 12 and the operation is simple and easy.

[0042] In some embodiments, please refer to the appendix Figure 2 The opening section 2 includes a lifting area 21 and a sealing area 22, which are separated from each other. Specifically, the lifting area 21 corresponds to the wavy weak sealing structure, and the sealing area 22 corresponds to the strip-shaped weak sealing structure. A slit separates the lifting area 21 and the sealing area, facilitating the application of force to different parts and ensuring that the weak sealing area 12 can be easily torn open.

[0043] In some embodiments, please refer to the appendix Figure 3 The bag body 1 includes a first sheet 13 and a second sheet 14. A chamber is formed by fusing the peripheries of the first sheet 13 and the second sheet 14 together. A tear 15 is provided on one side of each of the first sheet 13 and the second sheet 14. The tear 15 is used to tear one side of the first sheet 13 and the second sheet 14, thus creating an opening in the bag body 1. Specifically, using the first sheet 13 and the second sheet 14 to form the bag body 1 simplifies the folding operation of the sheets in the factory, thereby improving the production efficiency of the bag body 1. By providing the tear 15, an opening is formed on one side of the bag body 1, making it easy for the user to tear open and quickly use the bag. This facilitates the user in removing the contents of the bag body 1 from the opening. The ingenious structural design enhances the user experience.

[0044] Example 2:

[0045] The difference between this embodiment and Embodiment 1 is that the surface of the opening part 2 in this embodiment is provided with an anti-slip layer. When the user's hands contain water or oil, the bag may slip when opened. This feature increases the contact force between the user's hand and the opening part 2 during pulling, which is equivalent to increasing the friction between the two, thereby avoiding the difficulty of opening the bag due to slippage, improving the ease of opening, and making it suitable for various applications of packaging bags, with strong adaptability.

[0046] Preferably, the anti-slip layer is a structure formed by a number of raised dots. This design increases the friction between the raised dots and the user's hand when the user's hand contacts the anti-slip layer, reducing slippage and facilitating operation of the opening section 2, making opening the bag convenient and easy. It also prevents the packaging bag from falling due to slippage, thus ensuring the quality of opening. Preferably, the surface of the raised dots can be arc-shaped, which improves the user's comfort when pulling the opening section 2.

[0047] Example 3:

[0048] The difference between this embodiment and Embodiment 1 is that the opening part 2 in this embodiment has at least one pull hole. When the user's hands are wet or oily, the bag may slip when opening. This design allows the user's hand to pass through the pull hole and pull the opening part 2. The pull hole provides a fulcrum for the user's hand, improving ease of operation and facilitating easy opening of the weakly sealed area 12. Preferably, the opening part 2 has three pull holes, facilitating the user to pull different parts of the opening part 2 and further improving ease of operation.
