Description

TECHNICAL FIELD

[0001] The present application relates to a wiping article. BACKGROUND

[0002] Wiping articles are widely used in daily life and industry for cleaning and wiping the skin or the surface of an article. The most common wiping articles at present include paper towels, wet wipes and the like, which are usually stacked in a package bag or a package box in a stacked form and taken by a user through a draw opening.

[0003] In order to facilitate continuous drawing, it is a common practice to stack the wiping articles in an interleaved (e.g. Z-shaped) folded manner. When a user draws out one wiping article, the next one is brought out of the draw opening with the aid of the friction force (sometimes the pulling force formed by folding) between the wiping articles, thereby facilitating subsequent drawing. However, this friction-dependent method has obvious defects: when the number of wiping articles in the package is sufficient, the stacking pressure is large, the friction force is large, and the bringing-out effect is acceptable; but when the number of wiping articles in the package gradually decreases (e.g. less than one-third of the remaining amount), the pressure of the stack on the uppermost wiping article is significantly reduced, and the friction force between the wiping articles is also reduced, which easily leads to the failure to bring out the next wiping article, i.e. the "disconnection" phenomenon, and the user has to reach into the bag to take the paper, which is extremely inconvenient.

[0004] In order to solve the above-mentioned disconnection problem, the prior art has appeared a scheme of connecting adjacent wiping articles by a connecting part. For example, documents such as Chinese patent CN217772175U and US20020074375A1 disclose that a connecting part is arranged in the middle region between adjacent wiping articles, and a weakening line (such as a perforation line or an indentation line) is preformed on the connecting part; when drawing, the previous wiping article pulls the next wiping article towards the draw opening through the connecting part, and when the connecting part passes through the draw opening, the wiping article is separated from the weakening line under the action of the resistance of the opening edge of the package bag or the pulling force applied by the user.

[0005] This scheme has relatively good separation effect when the stack of wiping articles in the package is relatively full and the stack itself is relatively heavy. However, it is found in practice that when the wiping articles in the package are taken out in large quantities, the stack becomes loose and is greatly lowered (in a half-empty state), and this scheme easily leads to a new problem: multiple wiping articles are drawn out at a time, i.e. the so-called "continuous drawing" phenomenon.

[0006] In one improvement, as shown in patent document CN107438385A, a connecting portion is provided at the edge to utilize the force moment during extraction and the gravity of the next wipe to make the adjacent wipes easily separate, thereby reducing the continuous extraction phenomenon, but for this arrangement, there is still the same problem, that is, to ensure that the next wipe can be effectively taken out when the package is full, the connecting portion needs to have sufficient tensile strength; but when the contents of the package are reduced, the stack becomes loose, and if the strength of the connecting portion is still large, it is difficult to separate smoothly, resulting in the "continuous extraction" phenomenon of taking out multiple wipes at a time, and vice versa, if a lower connecting strength is used to avoid "continuous extraction", it is also easy to break prematurely during the taking-out process when the package is full, resulting in "discontinuous extraction".

[0007] That is, under the existing arrangement, the position, spacing and strength of the connecting portion are fixed on all wipes and cannot dynamically adapt to the continuous changes in stack pressure, friction and center of gravity from the full package to the empty package. Therefore, its improvement effect on "discontinuous extraction" and "continuous extraction" is still limited and has not fundamentally solved this technical contradiction.

[0008] Therefore, a new technical solution is needed to solve the above technical problems. SUMMARY

DETAILED DESCRIPTION

[0022] Please refer to Figures 1 to 3 , the embodiment of the present application provides a wiping article, comprising a packaging body 20 having a containing space and a folded body 100 contained in the containing space.

[0023] The package 20 is formed by a package sheet 21, and the package sheet 21 comprises a top sheet 21, and the top sheet 21 is provided with a draw opening 211, and the folding body 100 comprises a plurality of wiping bodies 10, and the wiping body 10 comprises a plurality of wiping sheets connected with each other, and the wiping sheets are continuously and stably drawn out through the draw opening 211, and the continuous and stable drawing means that when the wiping sheets are drawn out, the previous wiping sheet can stably take out the next wiping sheet, and the frequency of continuous drawing is reduced, and the wiping sheets can be thin materials such as non-woven fabric, cotton cloth, cellulose fiber tissue, and the like, and are not limited herein, and the wiping body 10 is accommodated in the accommodation space in a folded form, and the folding can be Z-shaped folding, N-shaped folding or V-shaped folding.

[0024] The wiping body 10 comprises a length direction and a width direction, and in the embodiment, the wiping body 10 extends along the length direction, and the direction perpendicular to the length direction is the width direction, and Figure 2 The extension of the wiping body 10 is shown as the up-down direction on the paper in Figure 2 The length direction of the wiping body 10 is shown as the up-down direction on the paper, and the width direction of the wiping body 10 is shown as Figure 1 the left-right direction on the paper, and the wiping body has a left end portion 101 and a right end portion 102 oppositely arranged in the width direction, and a center line 103 is defined, and the center line 103 is equidistant from the left end portion 101 and the right end portion 102.

[0025] In the embodiment, the wiping body 10 comprises a first wiping piece 11, a second wiping piece 12, a third wiping piece 13 and a fourth wiping piece 14 arranged in sequence along the length direction of the wiping body 10, and further comprises a first connecting part 111 connecting the first wiping piece 11 and the second wiping piece 12, a second connecting part 121 connecting the second wiping piece 12 and the third wiping piece 13, and a third connecting part 131 connecting the third wiping piece 13 and the fourth wiping piece 14. The first wiping piece 11, the second wiping piece 12, the third wiping piece 13 and the fourth wiping piece 14 form an interconnected whole through the first connecting part 111, the second connecting part 121 and the third connecting part 131. The first wiping piece 11 is arranged adjacent to the suction port 211. The first wiping piece 11 is the wiping piece located at the top end adjacent to the suction port 211. More specifically, if the wiping piece adhering to the top sheet 21 is defined as the first wiping piece, the wiping pieces connected to the first wiping piece in sequence are the second wiping piece, the third wiping piece, the fourth wiping piece, and so on. When the first wiping piece 11 is the Nth wiping piece, N≤5, preferably, N=1, i.e. the first wiping piece 11 is the wiping piece located at the top end and adhering to the top sheet 21.

[0026] The first connecting part 111, the second connecting part 121 and the third connecting part 131 are alternately arranged on both sides of the center line 103, the tensile strength of the first connecting part 111 is greater than that of the second connecting part 121, the alternately arranged means that when the first connecting part 111 is located on the left side of the center line 103, the second connecting part 121 is located on the right side of the center line 103, and the third connecting part 131 is located on the left side of the center line 103, the tensile strength can be tested by the test method of breaking strength in GB / T 3923.1-2013 Textiles - Determination of tensile properties of fabrics - Part 1: Breaking force and elongation at break (strip method), the direction of the tensile strength is the direction of separating the adjacent wiping sheet pair, specifically, in this embodiment, the direction of the tensile strength is along the length direction of the wiping body 10, it can be understood that the tensile strength of the first connecting part 111 is greater than that of the second connecting part 121, so that the force required for separating the first wiping sheet 11 and the second wiping sheet 12 on the upper side is greater than the force required for separating the second wiping sheet 12 and the third wiping sheet 13 on the lower side, that is, when the first wiping sheet 11 is pulled out, the second wiping sheet 12 is also pulled out, after the second wiping sheet 12 needs to be used, the upper space is increased, and the third wiping sheet 13 will be subjected to smaller clamping force or friction force when it is pulled out than when the second wiping sheet 12 is pulled out, the tensile strength of the first connecting part 111 is greater than that of the second connecting part 121, so that smaller force is required for separating the second wiping sheet 12 and the third wiping sheet 13, to adapt to the change of the height of the folding body 100.

[0027] Meanwhile, since the first connecting part 111, the second connecting part 121 and the third connecting part 131 are alternately arranged on both sides of the center line 103, a force moment exists between the force application position and the first connecting part 111, the second connecting part 121 and the third connecting part 131 during the extraction process, so that the first wiping sheet 11, the second wiping sheet 12, the third wiping sheet 13 and the fourth wiping sheet 14 are easily separated, thereby avoiding the continuous extraction phenomenon. More specifically, the first wiping sheet 11 comprises a first leading-out area 112 for being gripped by a user and a first pulling area 113 adjacent to the first connecting part 111, and the second wiping sheet 12 comprises a second leading-out area 122 adjacent to the first connecting part 111. When the first wiping sheet 11 is extracted, the first pulling area 113 drives the first connecting part 111 and the second leading-out area 122 to move, and the second wiping sheet 12 is pulled out of the extraction opening 211 through the second leading-out area 122. Since the first pulling area 113 and the first connecting part 111 are misaligned, when force is applied to the first pulling area 113, a force moment exists on the first connecting part 111, so that the first wiping sheet 11 and the second wiping sheet 12 are separated at the first connecting part 111 in the form of tearing. Similarly, the second wiping sheet 12 comprises a second pulling area 123, the third wiping sheet 13 comprises a third leading-out area 132 and a third pulling area 133, and the fourth wiping sheet 14 comprises a fourth leading-out area. When the first connecting part 111, the second connecting part 121 and the third connecting part 131 are alternately arranged, misalignment exists between the first leading-out area 112 and the second leading-out area 122, the second leading-out area 122 and the third leading-out area 132, and the third leading-out area 132 and the fourth leading-out area, thereby forming a force moment, which facilitates tearing at the first connecting part 111, the second connecting part 121 and the third connecting part 131.

[0028] Further, the first connecting part 111, the second connecting part 121 and the third connecting part 131 respectively include a first proximal end 1111, a second proximal end 1211 and a third proximal end 1311 adjacent to the center line 103, the distance between the first proximal end 1111 and the second proximal end 1211 is defined as D1, and the distance between the second proximal end 1211 and the third proximal end 1311 is defined as D2, then D1 < D2, so that the moment of force increases from the upper side to the lower side, so that the wiping sheet located on the lower side is more easily separated from the adjacent wiping sheet on the upper side. It can be understood that the first proximal end 1111 is the end of the first connecting part 111 closest to the center line 103, in this embodiment, the first proximal end 1111 is the right end of the first connecting part 111, the second proximal end 1211 is the end of the second connecting part 121 closest to the center line 103, in this embodiment, the second proximal end 1211 is the left end of the second connecting part 121, and the third proximal end 1311 is the end of the third connecting part 131 closest to the center line 103, in this embodiment, the third proximal end 1311 is the right end of the third connecting part 131.

[0029] Further, the first connecting part 111 further includes a weakening line 1113 for separating the first wiping sheet 11 and the second wiping sheet 12, the weakening line 1113 can be a score line, a perforation line, a micro-hole line, etc., through the weakening line 1113, the first wiping sheet 11 and the second wiping sheet 12 can be easily torn along the weakening line 1113.

[0030] Further, the weakening line 1113 is a perforation line, and the extension direction of the perforation line is parallel to the width direction of the wiping body 10.

[0031] Further, the perforation line includes a connecting segment and a perforation segment, and the virtual cutting ratio of the perforation line is 4:1-20:1, the virtual cutting ratio refers to the ratio of the length of the perforation segment to the length of the connecting segment in the perforation line of the connecting part.

[0032] Further, the width of the first connecting part 111 is greater than the width of the second connecting part 121, specifically, the first connecting part 111 further includes a first distal end 1112 opposite to the center line 103, the width of the first connecting part 111 is the distance between the first proximal end 1111 and the first distal end 1112, when the width of the first connecting part 111 is greater than the width of the second connecting part 121, on the one hand, the tensile strength of the first connecting part 111 can be easily greater than the tensile strength of the second connecting part 121, on the other hand, because the width of the first connecting part 111 is greater than the width of the second connecting part 121, more time is needed when tearing the first connecting part 111, so that the second wiping sheet 12 has enough area to be taken out, thereby facilitating use.

[0033] Further, the tensile strength of the first connecting part 111, the second connecting part 121 and the third connecting part 131 is set in a gradient.

[0034] Further, 2.0≥D2 / D1≥1.2, so that the third wiping sheet 13 and the fourth wiping sheet 14 can be stably pulled out and not be pulled out together, that is, when D2 / D1 is too small, the effect is not obvious, and when D2 / D1 is too large, the bottom wiping sheet is easily separated too early and the wiping sheet is broken.

[0035] Further, the distance between the first proximal end 1111 and the center line 103 is defined as L, and the distance between the left end 101 and the center line 103 is K, and L / K=1 / 8-1 / 2, so that the first proximal end 1111 is closer to the center line 103, so that the first wiping sheet 11 performs a tearing action in a shorter time during the pulling-out process, to improve the use experience, and further reduce the phenomenon of pulling out together.

[0036] Further, the extraction port 211 includes a boundary line 2111, and the boundary line 2111 includes an end point, which is the point on the boundary line 2111 farthest from the center line 103, and the end point is also located in the region defined by the proximal end and the distal end, so that the extraction port 211 has a suitable range, and during the extraction process, the packaging sheet at the extraction port 211 can form resistance to the wiping sheet, thereby helping the next wiping sheet to separate.

[0037] Further, the projection of the first connecting part 111 on the top sheet 21 intersects the boundary line 2111, so that during the extraction process, the connecting part is subjected to a squeezing action when passing through the extraction port 211, thereby helping the next wiping sheet to separate.

[0038] Further, the width of the first connecting part 111 is greater than 6mm.

[0039] The following will be further illustrated by specific embodiments: Embodiments

[0043] The package bodies of Example 1, Comparative Example 1 and Comparative Example 2 are subjected to extraction tests, and the first piece of wiping piece adjacent to the extraction port is extracted from the extraction port to the 80th piece during extraction, which is performed by the same tester. When multiple pieces are extracted, the extraction test is performed after auxiliary separation, and the test is repeated three times.

[0044] The test results are as follows: Item Example 1 Comparative Example 1 Comparative Example 2 Average number of pulls 3.3 9 6.3 Position of first occurrence of a pull (minimum value in 3 packs) 55th sheet 10th sheet 22nd sheet Number of times the next wipe sheet was not brought out 0 0 1 From the test results, it is found that the limiting effect of the packaging sheet on the subsequent wiping pieces is obviously reduced after the first three wiping pieces are extracted. When the stretching strength of the subsequent connecting part is maintained at the original strength to ensure the stable extraction of the preceding wiping pieces in the manner of Comparative Example 1 and Comparative Example 2, the phenomenon of continuous extraction is obviously present, that is, the wiping article of Example 1 is greatly reduced in the phenomenon of continuous extraction compared with Comparative Example 1 and Comparative Example 2, which is reduced by 63.3% compared with Comparative Example 1 and 47.6% compared with Comparative Example 2, and the time point of the phenomenon of continuous extraction is greatly later, and the problem of not taking out the next wiping piece is not easy to occur compared with Comparative Example 2.
