Description

Technical Field

[0001] This utility model relates to a wiping material. Background Technology

[0002] Wiping products are widely used in daily life and industry for cleaning and wiping skin or object surfaces. The most common wiping products include paper towels and wet wipes. These products are usually packaged in stacks in bags or boxes and dispensed by users through a pull-out spout.

[0003] To facilitate continuous dispensing, a common practice is to stack the wipes in an alternating (e.g., Z-shape) folded manner. When a user pulls out a wipe, the friction between the wipes (and sometimes the pulling force created by the folding) pulls the next wipe out of the dispenser, thus facilitating subsequent dispensing. However, this friction-based method has significant drawbacks: when there are enough wipes in the package, the stacking pressure is high, resulting in greater friction and a decent dispensing effect; but as the number of wipes in the package gradually decreases (e.g., less than one-third remaining), the pressure of the stack on the top wipe decreases significantly, and the friction between the wipes decreases accordingly. This can easily lead to the inability to dispense the next wipe, resulting in a "disconnection," forcing the user to reach into the bag to retrieve the wipe, which is extremely inconvenient.

[0004] To address the aforementioned disconnection problem, existing technologies have employed a connecting portion to link adjacent wipes. For example, Chinese Patent CN217772175U and US Patent US20020074375A1 disclose that a connecting portion is provided in the middle area between adjacent wipes, and a weakening line (such as a perforation line or an indentation line) is pre-made on the connecting portion. During extraction, the previous wipe pulls the next wipe towards the extraction port through the connecting portion. When the connecting portion passes through the extraction port, the wipe separates from the weakening line due to the obstruction at the edge of the packaging bag opening or the pulling force applied by the user.

[0005] This method works relatively well when the wipes inside the packaging are piled up quite full and the stack itself is heavy. However, in practice, it has been found that when a large number of wipes are removed from the packaging and the stack becomes loose and its height decreases (becoming semi-empty), this method is prone to causing new problems: multiple wipes are pulled out at once, a phenomenon commonly known as "continuous pulling".

[0006] In one improved solution, as shown in patent document CN107438385A, the connecting part is set at the edge to utilize the applied torque during the extraction process and the gravity of the next wiping item to make adjacent wiping items easier to separate, thereby reducing the phenomenon of consecutive extraction. However, this arrangement still has similar problems. In order to ensure that the next wiping item can be effectively pulled out when the package is full, the connecting part needs to have sufficient tensile strength. However, when the package is less full, the stack becomes loose. If the strength of the connecting part is still too high, it is difficult to separate smoothly, resulting in the phenomenon of "consecutive extraction" of multiple wiping items being pulled out at once. Conversely, if a lower connecting strength is used to avoid "consecutive extraction", it is very easy to break prematurely during the extraction process when the package is full, resulting in "broken connection".

[0007] In the existing configuration, the position, spacing, and strength of the connecting parts are fixed across all the wiping pads, making it impossible to dynamically adapt to the continuous changes in stacking pressure, friction, and center of gravity position during the process from a full package to an empty package. Therefore, its effect on improving the phenomena of "disconnection" and "continuous extraction" remains limited, failing to fundamentally resolve this technical contradiction.

[0008] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0022] Please see Figures 1 to 3 This utility model provides a wiping object, including a packaging body 30 with a accommodating space and a folded body 100 accommodated within the accommodating space.

[0023] The packaging body 30 is formed by packaging sheet material, which includes a top sheet 31 with a pull-out port 311. The folded body 100 includes several wiping bodies 10, each wiping body 10 including several interconnected wiping strips, for continuously and stably pulling out the wiping strips through the pull-out port 311. Continuous and stable pulling out means that when pulling out a wiping strip, the previous wiping strip can stably bring out the next wiping strip, reducing the frequency of continuous pulling. The wiping strips can be thin materials such as non-woven fabric, cotton cloth, or cellulose fiber paper, and there are no restrictions. The wiping body 10 is folded and housed in the accommodating space. The folding can be Z-shaped, N-shaped, or V-shaped.

[0024] The wiping body 10 includes a length direction and a width direction. In this embodiment, the wiping body 10 extends along its length direction, and the direction perpendicular to the length direction is the width direction. Figure 2 The image shows the wiping body 10 extending vertically on the paper surface, i.e. Figure 2 The length direction of the wiping body 10 shown is the vertical direction of the paper surface, while the width direction of the wiping body 10 is... Figure 1 In the left-right direction of the paper, the wiping material has a left end 101 and a right end 102 that are arranged opposite each other in the width direction. At the same time, a center line 103 is defined, which is equidistant from the left end 101 and the right end 102.

[0025] In this embodiment, the wiping body 10 includes a plurality of wiping pads arranged sequentially along its length. A connecting portion is provided between adjacent wiping pads. The connecting portion includes a proximal end near the center line. The distance between the proximal ends of adjacent connecting portions and the center line is different, thereby causing the center of gravity of adjacent wiping pads to change during the extraction process, making it easier to extract the next wiping pad. Specifically, in this embodiment, the wiping body 10 includes a first wiping pad 11, a second wiping pad 12, and a third wiping pad 13 arranged sequentially along its length. A first connecting portion 21 connecting the first wiping pad 11 and the second wiping pad 12 is provided between them, and a second connecting portion 22 connecting the second wiping pad 12 and the third wiping pad 13 is provided between them. 21 and the second connecting part 22 enable the first wiping pad 11, the second wiping pad 12 and the third wiping pad 13 to form an interconnected whole. The first wiping pad 11 is configured to be adjacent to the extraction port 311. The meaning of "adjacent to the extraction port 311" is that the folded body 100 includes a top end adjacent to the extraction port 311, and the first wiping pad 11 is the wiping pad located at the top end and adjacent to the extraction port 311. More specifically, "adjacent" means that if the wiping pad that is attached to the top piece 31 is defined as the first wiping pad, and the wiping pads connected to the first wiping pad are the second wiping pad, the third wiping pad, ... the Nth wiping pad, then when the first wiping pad 11 is the Nth wiping pad, N≤5. Preferably, N=1, that is, the first wiping pad 11 is the wiping pad located at the top end and attached to the top piece 31.

[0026] The first connecting portion 21 and the second connecting portion 22 respectively include a first proximal end 211 and a second proximal end 221 adjacent to the center line 103. The distance between the first proximal end 211 and the center line 103 is defined as D1, and the distance between the second proximal end 221 and the center line 103 is defined as D2. Then D2 > D1. On the one hand, this increases the torque from the top to the bottom, making it easier for the wiping pad located on the bottom to separate from the adjacent wiping pad on the top. On the other hand, when the first wiping pad 11 is pulled out, the position of the second wiping pad 12 extending out of the extraction port 311 is different from the position of the third wiping pad 13 extending out of the extraction port 311. Furthermore, the center of gravity of the second wiping pad 12 during the extraction process is different from that of the third wiping pad 13 during the extraction process. This further makes it easier for the wiping pad located on the bottom to separate from the adjacent wiping pad on the top. At the same time, it makes it easier for the next wiping pad to separate from the previous wiping pad during the extraction process.

[0027] In addition, the first proximal end 211 is the end of the first connecting portion 21 that is closest to the center line 103. In this embodiment, the first proximal end 211 is the right end of the first connecting portion 21. The second proximal end 221 is the end of the second connecting portion 22 that is closest to the center line 103. In this embodiment, the second proximal end 221 is the right end of the second connecting portion 22.

[0028] Furthermore, the wiping body 10 also includes a fourth wiping pad 14, and a third connecting portion 23 is included between the third wiping pad 13 and the fourth wiping pad 14. The third connecting portion 23 includes a third proximal end 231. The distance between the third proximal end 231 and the center line 103 is defined as D3. Then, D3 > D2 > D1, that is, the distance between the connecting portion and the center line 103 increases sequentially.

[0029] Furthermore, D3, D2, and D1 are arithmetic sequences.

[0030] Furthermore, the first connecting part 21, the second connecting part 22, and the third connecting part 23 are all located on the same side of the center line.

[0031] Furthermore, the first connecting part 21 also includes a weakening line 210 for separating the first wiping pad 11 and the second wiping pad 12. The weakening line 210 can be an indentation line, a perforation line, a micro-perforation line, etc. The weakening line 210 makes it easy for the first wiping pad 11 and the second wiping pad 12 to be torn along the weakening line 210.

[0032] Furthermore, the weakening line 210 is a perforated line, and the extension direction of the perforated line is parallel to the width direction of the wiping body 10.

[0033] Furthermore, the perforated line includes a connecting section and a perforated section. Meanwhile, the virtual shear ratio of the perforated line is 4:1 to 20:1. The virtual shear ratio refers to the ratio of the length of the perforated section to the length of the connecting section in the perforated line of the connecting part.

[0034] Furthermore, the width of the first connecting portion 21 is greater than the width of the second connecting portion 22. Specifically, the first connecting portion 21 also includes a first distal end 212 facing away from the center line 103. The width of the first connecting portion 21 is the distance between the first proximal end 211 and the first distal end 212. When the width of the first connecting portion 21 is greater than the width of the second connecting portion 22, on the one hand, it is easier to make the tensile strength of the first connecting portion 21 greater than the tensile strength of the second connecting portion 22. On the other hand, since the width of the first connecting portion 21 is greater than the width of the second connecting portion 22, more time is required when tearing the first connecting portion 21, so that the second wiping pad 12 has a sufficient area to be pulled out, thus facilitating its use.

[0035] Furthermore, the distance between the first proximal end 211 and the center line 103 is defined as L, and the distance between the left end 101 and the center line 103 is defined as K. Then L / K = 1 / 8 to 1 / 2, which makes the first proximal end 211 closer to the center line 103, thereby making the first wiping pad 11 tear in a shorter time during the extraction process, so as to improve the user experience and further reduce the phenomenon of continuous extraction.

[0036] Furthermore, the width of the first connecting part 21 is greater than or equal to 6 mm.

[0037] Furthermore, D2-D1≥2mm, and D3-D2≥2mm.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
