Description

Technical Field

[0001] This utility model relates to an interconnected wiping material and packaging body. 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 performs relatively well when the wipes inside the packaging are fully stacked 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 easily leads to a new problem—the "continuous extraction" phenomenon (i.e., multiple wipes are extracted at once). This may be because the reduced weight of the stack decreases the pressure on the wipes at the bottom, altering the radial constraint or friction force experienced by the connecting part when passing through the extraction port, making the separation force required for the weakened line unstable. Simultaneously, the design of the connecting part in the middle may result in a longer lever arm for the pulling force, making it more prone to incomplete separation due to torque changes when the packaging is semi-empty. This contradicts the problem of "breakage" in staggered folding stacks when the bag is empty.

[0006] In addition, when the connection is set at the edge, the long torque during the extraction process makes separation too easy. In order to ensure that the next wiping pad can be extracted smoothly when the stack is full, a large connection strength is usually required. However, the large connection strength leads to the phenomenon of "continuous extraction" after the stack becomes loose and the height decreases (into a semi-empty state).

[0007] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0008] To address this issue, the present invention provides an interconnected wiping material and packaging body to solve the aforementioned technical problems.

Detailed Implementation

[0021] Please see Figures 1 to 3 The first embodiment of this utility model provides an interconnected wiping object 100, including multiple wiping pads interconnected by connecting parts, which can be continuously and stably extracted through the extraction port 21 after forming a stacked body 10 or a wound body. The meaning of continuous and stable extraction is that when the wiping pad is extracted, the previous wiping pad can stably bring out the next wiping pad, which significantly reduces the frequency of continuous extraction. The wiping pads can be thin materials such as non-woven fabric, cotton cloth, and cellulose fiber paper, and are not limited here.

[0022] The wiping material 100 includes a length direction and a width direction. In this embodiment, the extending direction of the wiping material 100 is the length direction, and the direction perpendicular to the length direction is the width direction. Simultaneously, the extending direction of the wiping material 100 is the extension direction of a plurality of interconnected wiping pads. Figure 1 The image shows three interconnected wiping pads, extending in the vertical direction on the paper. Figure 1 The length direction of the wiping object 100 shown is the vertical direction of the paper surface, while the width direction of the wiping object 100 is... Figure 1 The left and right directions of the middle paper.

[0023] For ease of understanding, Figure 1 The three interconnected wiping pads shown are referred to from top to bottom as the first wiping pad 11, the second wiping pad 12, and the third wiping pad 13. A first connecting portion 110 is included between the first wiping pad 11 and the second wiping pad 12, and a second connecting portion 120 is included between the second wiping pad 12 and the third wiping pad 13. At the same time, the first wiping pad 11, the second wiping pad 12, and the third wiping pad 13 are all rectangular and have the same size. It can be understood that in other embodiments, adjacent wiping pads may have different sizes, such as different lengths.

[0024] The wiping pad 100 has a left end 101 and a right end 102 disposed opposite each other in the width direction. A first virtual center line 1001 is defined, which is equidistant from the left end 101 and the right end 102. A second virtual center line 1002 is defined, which is located between the first virtual center line 1001 and the left end 101, and is equidistant from both. A third virtual center line 1003 is defined, which is located between the first virtual center line 1001 and the second virtual center line 1002, and is equidistant from both. The connecting portion includes a weakening line 1100 for separating adjacent wiping pads, and the main part or all of the connecting portion is located within the area defined by the second virtual center line 1002 and the third virtual center line 1003. The main part means 75% or more of the width of the connecting portion.

[0025] Research has found that when the main part or all of the connecting portion is placed within the area defined by the second virtual centerline 1002 and the third virtual centerline 1003, the following technical effects are achieved: The first virtual center line 1001 is actually equivalent to the center line of the wiping object 100. With the above-mentioned arrangement, the connecting part is actually offset to one side of the first virtual center line 1001. When the user applies force to the upper end of the first wiping pad 11, the point of force application is misaligned with the connecting part, so that a greater force is applied to the end of the connecting part near the first virtual center line 1001 during the extraction process, making it easier for the first wiping pad 11 and the second wiping pad 12 to separate. In particular, compared with the setting method of CN217772175U, it is easier to separate and reduce the phenomenon of continuous extraction.

[0026] Meanwhile, if the connecting part is set near the left end 101 or the right end 102, on the one hand, a larger torque is formed on the end of the connecting part near the first virtual center line 1001 when it is pulled out, so that when the second wiping strip 12 is pulled out, it separates too quickly under the gravity of the second wiping strip 12, resulting in the inability to pull out the next wiping strip. Alternatively, when the wiping strip at the extraction port 21 can be stably pulled out and separated, it will be impossible to stably separate and form continuous extraction when a part of the empty space is formed in the packaging body 20. However, when the main part or all of the connecting part is set in the area defined by the second virtual center line 1002 and the third virtual center line 1003, the connecting part is not too close to the left end 101 or the right end 102, thereby forming a stable extraction and reducing continuous extraction.

[0027] With the above arrangement, compared with the form where the connecting part is placed in the middle, the overall continuous draw rate is reduced by 55.6%. Compared with the form where the connecting part is placed at the left end 101 or the right end 102, the probability of continuous draw is reduced by 33% after the 10th piece, thus achieving a balance between reducing the probability of continuous draw and ensuring stable draw.

[0028] Furthermore, all of the connecting portions are located within the area defined by the second virtual centerline 1002 and the third virtual centerline 1003.

[0029] Furthermore, the weakening line 1100 is a perforated line, and the extension direction of the perforated line is parallel to the width direction of the wiping object 100.

[0030] 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.

[0031] Furthermore, if the distance between the second virtual centerline 1002 and the third virtual centerline 1003 is defined as R, and the width of the connecting part is L, then L / R = 0.2-0.8.

[0032] Furthermore, L is greater than or equal to 4 mm.

[0033] Furthermore, the connecting portion includes a first end 111 adjacent to the second virtual center line 1002 and a second end 112 adjacent to the third virtual center line 1003. The distance between the first end 111 and the second virtual center line 1002 is greater than 2 mm, and the distance between the second end 112 and the third virtual center line 1003 is greater than 2 mm.

[0034] Furthermore, both the first connecting portion 110 and the second connecting portion 120 are located within the area defined by the second virtual centerline 1002 and the third virtual centerline 1003.

[0035] Please refer to this as well. Figure 5 A fourth virtual centerline 3004 is defined, which is located between the first virtual centerline 3001 and the right end 302, and is equidistant from both. A fifth virtual centerline 3005 is defined, which is located between the first virtual centerline 3001 and the fourth virtual centerline 3004, and is equidistant from both. The wiping object 300 includes a first wiping pad 31, a second wiping pad 32, and a third wiping pad 33. A first connecting portion 310 connecting the first wiping pad 31 and the second wiping pad 32 is included between the first wiping pad 31 and the second wiping pad 32. A second connecting portion 320 connecting the second wiping pad 32 and the third wiping pad 33 is included between the second wiping pad 32 and the third wiping pad 33. The first connecting portion 310 is located within the area defined by the second virtual centerline 3002 and the third virtual centerline 3003, and the second connecting portion 320 is located within the area defined by the fourth virtual centerline 3004 and the fifth virtual centerline 3005.

[0036] Please refer to this as well. Figure 1 and Figure 4 This embodiment also provides a packaging body 20, which includes a packaging sheet surrounding a accommodating space and a stacked body 10 disposed within the accommodating space. The stacked body 10 is formed by folding the interconnected wiping materials 100. The folding can be a Z-shaped fold, an N-shaped fold, or a V-shaped fold. In other embodiments, the interconnected wiping materials 100 are wound to form a wound body, which is wound within the accommodating space.

[0037] The packaging body 20 includes a dispensing port 21 for dispensing a wiping pad. The dispensing port 21 includes an edge line 211 and an endpoint 2110. The endpoint 2110 is the point on the edge line 211 that is furthest from the first virtual center line 1001. The endpoint 2110 is also located within the area defined by the second virtual center line 1002 and the third virtual center line 1003, so that the dispensing port 21 has a suitable range. At the same time, during the dispensing process, the packaging sheet at the dispensing port 21 can form resistance to the wiping pad, thereby helping the next wiping pad to be separated.

[0038] Furthermore, the packaging sheet includes a top sheet, the extraction port 21 is disposed on the top sheet, and the projection of the connecting part on the top sheet intersects with the edge line 211, so that the connecting part is squeezed during the extraction process as it passes through the extraction port 21, thereby helping the next wiping sheet to separate.

[0039] The following specific examples further illustrate this point: Example

[0040] Packaging: The contents are 80 interconnected wiping pads. Wiping pad: 55gsm spunlace nonwoven fabric + wet wipe liquid, size: 200mm*160mm, width of the connecting part: 15mm, the position of the connecting part is: the first end is 42mm away from the left end (the first virtual center line is 80mm away from the left end, the second virtual center line is 40mm away from the left end, the third virtual center line is 60mm away from the left end, so the connecting part is located in the area between the second virtual center line and the third virtual center line), and each connecting part is located on the side of the first virtual center line facing the left end.

[0041] Comparative Example 1: The packaging sheet and packaging form of the packaging body are the same as those in Example 1, and are arranged in the manner shown in CN217772175U. The contents are the same as those in Example 1, and the connecting part is located in the middle of the adjacent wiping sheet (its first end is 61.5 mm from the left end).

[0042] Comparative Example 2: The packaging sheet and packaging form of the packaging body are the same as those in Example 1, and its contents are the same as those in Example 1. The connection part is located on the far left of the adjacent wiping sheet (its first end is 0mm away from the left end).

[0043] Extraction tests were conducted on the packaging of Example 1, Comparative Example 1, and Comparative Example 2. During extraction, the first swab from the extraction port to the 80th swab was extracted. The same tester performed the extraction. If multiple swabs were extracted consecutively, they were separated before the extraction test was repeated. This was repeated 3 times.

[0044] The test results are as follows: Average number of consecutive draws 4 9 6 The first time a consecutive draw occurs (the minimum value among 3 packs). Film No. 42 10th film 25th film Number of times the next swab was not carried out 0 0 1 The test results show that the interconnected wiping material of Example 1 has significantly reduced the phenomenon of continuous wiping compared with Comparative Example 1 and Comparative Example 2. At the same time, the time point when the phenomenon of continuous wiping occurs is also later, and it is less likely to have the problem of not carrying out the next wiping pad compared with Comparative Example 2.

[0045] 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.
