Detailed Implementation

[0027] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In existing hygiene product packaging technologies, some products such as tissues and wet wipes use pre-installed tear lines for opening. This approach has two significant drawbacks: 1) When the tear is too large, the integrity of the packaging structure is compromised, easily leading to the contents scattering disorderly; 2) When the tear is insufficient, the resilience of the packaging material and the stacking of the contents make effective retrieval difficult. This uncontrollable opening directly impacts the user experience and product protection performance.

[0031] To solve the above technical problems, such as Figure 1-2 As shown, this embodiment provides a packaging bag, including a packaging bag body 1, the packaging bag body 1 having a packaging cavity formed inside for accommodating a sanitary sheet product 3; along a direction parallel to the stacking direction of the sanitary sheet product 3, the side wall of the packaging bag body 1 is provided with a plurality of independent opening forming portions 11, at least one edge of the opening forming portion 11 is provided with a dotted connection line 12, and each opening forming portion 11 can be torn open along the corresponding dotted connection line 12;

[0032] Each of the opening forming portions 11 is separated from each other to prevent the tearing of each opening forming portion 11 from occurring together.

[0033] Specifically, the sanitary sheet product 3 packaged in the packaging bag provided in this embodiment can be, but is not limited to, wet wipes, dry wipes, towels, sanitary napkins, and other hygiene products. It is especially suitable for high-capacity, stacked packaging. When in use, the highest opening forming part 11 is torn open first to facilitate the user to take out the top part of the sanitary sheet product 3. When the top opening is higher than the amount of sanitary sheet product 3 in the packaging bag, the second opening forming part 11 can be torn down to form a lower opening for easy access to the sanitary sheet product 3. This process is repeated to ensure convenient access while making full use of the packaging space and adapting to different inventory levels.

[0034] In the structure of the packaging bag provided in this embodiment, multiple independent opening forming parts 11 are arranged parallel to each other on the side wall of the main body 1 of the packaging bag along the stacking direction of the sanitary sheet products 3 (generally stacked from bottom to top). Each opening forming part 11 has at least one edge with a dotted connecting line 12. This design allows the opening forming part 11 to be torn along the dotted connecting line 12 to form an opening. The dotted connecting line 12 maintains the integrity of the packaging and clearly defines the tearing position, preventing the tearing width from being too large or too small. The multiple opening forming parts 11 are arranged in the stacking direction and can be torn layer by layer. When using it for the first time, the highest opening forming part 11 is torn open. As the contents decrease, other opening forming parts 11 can be torn downwards to ensure that the opening position is always convenient for accessing the top sanitary sheet product 3, improving the flexibility and adaptability of use.

[0035] Each opening forming part 11 is separated from the others, so that when any one opening forming part 11 is torn open, the other opening forming parts 11 will not be torn open as well, thus maintaining the stability of the opening forming parts 11. The corresponding opening forming part 11 can only be torn open when the user actively intends to do so, thus avoiding the problem of accidental tearing.

[0036] In summary, the packaging bag provided in this embodiment has at least the following beneficial effects:

[0037] 1) Improve user experience: The size and position of the opening are controllable, allowing users to accurately take out sanitary sheet products 3, avoiding scattering and difficulty in taking out, improving the convenience and comfort of use, especially in large-capacity packaging, which can effectively reduce waste and improve usage efficiency.

[0038] 2) Enhanced product protection performance: The opening forming part 11 can be opened as needed, and the opening size is moderate, reducing the impact of external factors on the contents, keeping the sanitary sheet product 3 clean, extending the shelf life, and better protecting the product.

[0039] 3) Improve packaging applicability and economy: Applicable to a variety of sanitary sheet products 3, especially suitable for large-capacity high-stack packaging. The reasonable design of the number and position of the opening forming part 11 can reduce the use of packaging materials, reduce costs, and improve economy.

[0040] In one embodiment, at least one partition film 14 is provided inside the main body of the packaging bag along a direction parallel to the stacking direction of the sanitary sheet product 3, the partition film 14 dividing the packaging cavity into multiple independent compartments; wherein, each compartment has an opening forming part 11 on its sidewall.

[0041] At least one separator film 14 is arranged parallel to and spaced along the stacking direction of the sanitary sheet products 3 inside the main body of the packaging bag 1, dividing the packaging cavity into multiple independent compartments. Each compartment has an opening forming part 11 on its sidewall. The separator film 14 makes the internal structure of the packaging bag layered, clearly defining the boundaries of each compartment and ensuring independence and integrity. The opening forming part 11 of each compartment is set independently and can be torn open individually without affecting the integrity of other compartments. This ensures that when some opening forming parts 11 are opened, they will not interfere with the sanitary sheet products 3 packaged in the remaining compartments, maintaining the airtightness and hygiene of the remaining products, that is, keeping the sanitary sheet products 3 clean and dry, and extending their shelf life.

[0042] In one embodiment, reference is made to Figure 3 Alternatively, in case any two adjacent opening forming portions 11 are provided with a tear-resistant area 15, and the point-break connecting line 12 does not pass through the tear-resistant area 15, thereby separating the adjacent opening forming portions 11 from each other through the tear-resistant area 15.

[0043] Specifically, when one of the opening forming portions 11 is torn open, the tear-stopping area 15 will not be torn open along with it after it is torn open. Therefore, the setting of the tear-stopping area 15 achieves the purpose of separating the two adjacent opening forming portions 11 and avoids the problem of accidental tearing.

[0044] In one embodiment, the tear-resistant area 15 is connected to one of the adjacent opening forming portions 11, and a dividing solid line 151 is provided between it and the other adjacent opening forming portion 11.

[0045] Specifically, at the location where the dividing solid line 151 is set, the tear-resistant area 15 is easily separated from the adjacent opening forming part 11. Therefore, the user can easily untie the tear-resistant area 15 at this location and then use the tear-resistant area 15 to tear open the connected opening forming part 11 together. Thus, this structure has the advantage of making it convenient for the user to tear open the opening forming part 11 when using it.

[0046] Preferably, the tear-resistant area 15 is configured as a protruding shape of the relatively connected opening forming portion 11 to facilitate user gripping.

[0047] In a specific implementation, in one embodiment, the dotted connection line 12 extends to connect with the dividing solid line 151. In this way, when one of the opening forming portions 11 is torn open, the film of the entire opening forming portion 11 can be separated from the main body of the packaging bag 1, and the separation will not be carried to the next adjacent tear-resistant area 15 due to the isolation of the dividing solid line 151.

[0048] In another embodiment, the dotted connecting line 12 does not extend to connect with the dividing solid line 151. Thus, when one of the opening forming portions 11 is torn open, the film of the torn opening forming portion 11 still has one side connected to the packaging bag body 1, forming only one opening on the packaging bag body 1.

[0049] In one embodiment, such as Figure 3 As shown, the point-break connecting line 12 includes a first point-break line 121 that is a broken line, and the inner corner region of the first point-break line 121 forms a first tearable area 111 that is triangular in shape.

[0050] The point-break connecting line 12 of the opening forming part 11 of the packaging bag is in the shape of a zigzag line, forming the first point-break line 121, and forming a triangular first tearable area 111 in the inner corner area of ​​the zigzag line. This design gives the opening forming part 11 a clear tearable area and direction. The formation of the triangular area is conducive to concentrating the tearing force, ensuring a smooth and accurate tearing process.

[0051] When a user needs to open the packaging, they begin tearing from the middle of the first tear line 121. Due to the zigzag design and the presence of the triangular tearable area, the tearing force gradually spreads along the first tear line 121, causing the opening to gradually widen. This design utilizes the tearing properties of the material, guiding the tearing direction by setting zigzags and triangular areas at specific locations, ensuring that the opening forms as expected, and avoiding packaging damage and product spillage caused by random tearing.

[0052] In another embodiment, refer to Figure 4 The point-break connecting line 12 includes an arc-shaped first point-break line 121, and the inner circular region of the first point-break line 121 forms a semi-circular first tearable area 111.

[0053] Similarly, an arc-shaped first point break connecting line 12 will be set. When the user needs to open the packaging bag, the tearing will start from the middle of the first point break line 121. Due to the arc design and the existence of the semi-circular tearable area, the tearing force will gradually spread along the first point break line 121, making the opening gradually expand. This ensures that the formation of the opening meets expectations and avoids packaging damage and product scattering caused by random tearing.

[0054] In one embodiment, the point-break connecting line 12 further includes two parallel second point-break lines 122, with each end of the first point-break line 121 connected to a second point-break line 122; a square-shaped second tearable area 112 is formed between the two second point-break lines 122 and connected to the first tearable area 111.

[0055] The point-break connecting line 12 of the opening forming part 11 of the packaging bag includes an arc-shaped first point-break line 121 and two parallel second point-break lines 122. Each end of the first point-break line 121 is connected to a second point-break line 122, forming a square-shaped second tearable area 112 between the two second point-break lines 122. This second tearable area 112 is connected to the fan-shaped first tearable area 111 formed by the first point-break line 121. This design combines zigzag / arc lines with straight point-break lines, forming a tearing structure that has both triangular / arc guidance and straight-line expansion, giving the opening forming part 11 a clearer tearing path and a larger controllable opening area. The square opening formed after tearing the second tearable area 112 matches the width of the sanitary sheet product 3, making it easier for users to remove the product and improving ease of use.

[0056] In one embodiment, a tearing gripper 13 is provided on the first tearable area 111 at the middle position near the first point break line 121.

[0057] On the first tearable area 111, a tear-grabbing tab 13 is provided at the middle position near the first break line 121. This tab is a small piece that is easy for the user to insert and grasp with their fingers. It is usually made of the same material as the main body of the packaging bag, but has a certain strength and toughness to withstand the pulling force when tearing. When using it, the user first inserts their finger into the gap between the tear-grabbing tab 13 and the main body 1 of the packaging bag, gently pulls up the tab, and then applies pulling force along the direction of the first break line 121. Due to the connection between the tab and the first tearable area 111, the pulling force will be concentrated in the middle of the break line, causing the break line to gradually tear from the middle to form an opening.

[0058] The design of the tear-off gripper 13 allows users to easily and accurately find the starting point for tearing, providing great convenience. Users can easily pull up the gripper and tear the packaging along the tear line, avoiding the difficulties caused by not being able to find the tearing position or applying enough pulling force, thus improving the convenience and comfort of use.

[0059] In one embodiment, the tear-off gripper 13 includes a first connecting area and a second connecting area, the first connecting area being connected to the first tearable area 111, and the second connecting area being connected to the side wall of the packaging bag body 1.

[0060] When the user pulls and tears the gripping piece 13, the second connecting area will first separate from the side wall of the main body 1 of the packaging bag. At this time, the connection between the second connecting area of ​​the gripping piece and the side wall is broken, while the first connecting area remains connected to the first tearable area 111. As the pulling force continues to be applied, the first break line 121 will gradually split, thereby causing the first tearable area 111 to gradually tear along the break line.

[0061] The dual-connection zone design ensures the orderly tearing process, allowing the untorn tear gripper 13 to remain attached to the surface of the main body 1 of the packaging bag, reducing the risk of it being accidentally torn due to warping.

[0062] In one embodiment, the first connecting area is bonded to the first tearable area 111, or the first connecting area and the first tearable area 111 are integrally connected structures.

[0063] The second connecting area is bonded to the side wall of the main body 1 of the packaging bag, or a point break structure is provided at the connection between the second connecting area and the main body 1 of the packaging bag.

[0064] The first connecting area and the first tearable area 111 can be connected by adhesive bonding or an integral connecting structure. Adhesive bonding can use glue or other adhesives, while the integral connecting structure designs the first connecting area and the first tearable area 111 as a whole, without the need for additional adhesive materials.

[0065] The second connection area can be connected to the side wall of the main body 1 of the packaging bag by adhesive bonding or by setting a dotted break line structure at the connection point. Adhesive bonding can also use glue or other adhesives, while the dotted break line structure is to pre-set some tiny breaks at the connection point so that the second connection area can be more easily separated from the side wall when subjected to force.

[0066] In all the connection methods of this embodiment, the tearing process can be guaranteed to be orderly and controllable, reducing the accidental damage to other parts of the packaging bag caused by weak connection or excessive force, and better protecting the integrity of the internal product.

[0067] In one embodiment, all the opening forming portions 11 are disposed on the same side wall of the packaging bag body 1.

[0068] By placing all the openings 11 on the same side wall, users can operate on the same side when taking out sanitary sheet products 3, without having to go around to other sides of the packaging bag to find the opening, which improves the convenience and efficiency of taking out the product.

[0069] In one embodiment, the package also includes a handle 2 connected to the top of the main body 1 of the packaging bag, the handle 2 having a hanging hole 21.

[0070] The top of the main body 1 of the packaging bag is connected to a handle 2, which is provided with a hanging hole 21. The handle 2 is usually made of thicker plastic to support the weight of the packaging bag. The hanging hole 21 is a small opening or hole, usually located in the center of the handle 2, for hanging the packaging bag.

[0071] The design of the handle 2 and the hanging hole 21 greatly improves the portability and practicality of the packaging bag, allowing users to easily carry it. The hanging hole 21 also allows the packaging bag to be conveniently hung on a wall hook for easy use.
