Description

Technical Field

[0001] The utility model relates to a disposable towel sheet, in particular to a tearable towel roll that can be pulled in different ways, and the towel sheet can be torn and separated from the towel roll in different ways. Background Art

[0002] A continuous polyester fiber cloth that can be torn into pieces is disclosed in the invention patent with the authorization announcement number CN114714730B. The fiber cloth includes a base layer woven by yarns and fluff layers arranged on both sides of the base layer. A thin strip of molten body is formed by heating, melting and pressing the base layer and the fluff layers, and the thickness of the thin strip of molten body is less than or equal to the thickness of the base layer; by tearing along the thin strip of molten body, independent single pieces of textile cloth can be separated.

[0003] In the prior art, such fiber cloth that can be torn into pieces can have the following two pulling and separating modes:

[0004] Mode 1: Side-pulling type. As disclosed in the utility model patent with the authorization announcement number CN218247029U for a bucket-type towel roll and a packaging bucket, a long and narrow opening is arranged on the arc-shaped side wall of the plastic packaging bucket along the length direction. The outermost periphery of the towel roll can be pulled out from the long and narrow opening, and the towel sheet can be separated from it. There is also a simpler way, which is to be used by threading it on a rod.

[0005] Mode 2: Central-pulling type. As disclosed in the utility model patent with the authorization announcement number CN218304666U for a pull-out dishcloth and a box body, an opening is arranged on one of the side walls of the box body, and a damping member with a damping channel is blocked on the opening of the box body; pulling the first dishcloth unit outwards through the damping channel and the opening of the box body, and the damping channel of the damping member always forms a certain damping force on the passing dishcloth unit; the whole process of pulling out the dishcloth unit only requires one-handed operation, which is more in line with the applicability convenience and operation speed of housewives or housework handlers.

[0006] For the side-pulling type towel roll of Mode 1, a supporting inner core is required in the center so that the towel roll can be supported by a certain fixed central axis, which can not only allow the towel roll to rotate but also provide a reverse force for tearing the towel sheet. For the second central-pulling type towel roll, the supporting inner core needs to be removed so that the towel roll can be pulled out from the central hole.

[0007] However, existing towel rolls are divided into two types, with a supporting inner core and without a supporting inner core, when they leave the factory. Consumers have to purchase according to their needs. Of course, there is a possibility of mis-purchasing. For example, the purchased towel roll does not match the pulling and separating mode supported by the towel roll box at home. Some users choose to remove the supporting inner core from the towel roll to transform it into a center-pulling type. However, due to the large winding force and adsorption force between the loops of the towel sheet wound around the supporting inner core, it is very difficult to take out the supporting inner core.

Detailed implementation manner

[0071] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present invention.

[0072] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. The terms "first" and "second" are only for descriptive convenience and have no other directional meaning, and should not be construed as a limitation of the present invention.

[0073] Embodiment One:

[0074] As Figures 1 to 4 shown is a tearable towel roll 100 that can be pulled out in different ways provided in this embodiment, including a central hole 110, a cylindrical supporting inner core 120 disposed in the central hole 110, and a tearable towel roll 130 wound around the outer periphery of the supporting inner core 120.

[0075] As Figure 1 shown, the tearable towel roll 130 includes a plurality of towel sheets 131 that are connected end to end and can be separated piece by piece. A polyester film tearable line M is formed between adjacent two towel sheets 131. During use, the towel sheets 131 can be torn and separated piece by piece along the polyester film tearable line M.

[0076] It should be understood that the tearable towel roll 100 that can be pulled out in different ways provided in this embodiment, due to the winding manner of the tearable towel roll 130, can at least achieve a side-pull type towel sheet pulling and separating mode, that is, starting from the outermost towel sheet 131, the towel sheets 131 are torn and separated from the tearable towel roll 130.

[0077] As Figures 2 to 4As shown, the support inner core 120 includes a peripheral side wall 123, a first end 121, and a second end 122. A spiral tear mark 10 extending from the edge of the first end 121 to the edge of the second end 122 is provided on the peripheral side wall 123. The support inner core 120 can be torn and disassembled at either end along the tear mark 10, and can be peeled off from most of the towel sheets 131 wound inside the tearable towel roll 130 in an inward rotation manner, and taken out from the central hole 110.

[0078] The structure of the tear mark 10 can be a single dotted line type, a double dotted line type, a fishbone line type, etc., which are more common in the prior art, and the present utility model does not limit this.

[0079] As Figure 2 shown, at least one pulling tongue 11 is provided on the inner peripheral wall of the peripheral side wall 123. The pulling tongue 11 is provided at at least one of the first end 121 and the second end 122 and is close to the end of the tear mark 10. The provision of the pulling tongue 11 can facilitate the user to quickly find the end of the tear mark 10 and easily tear the peripheral side wall 123 of the support inner core 120 by means of the pulling tongue 11.

[0080] As Figure 4 shown, at least a part of the innermost towel sheet 131 of the tearable towel roll 130 is adhered to the outer peripheral wall of the support inner core 120. When the support inner core 120 is taken out from the central hole 110, the innermost towel sheet 131 is brought out, so that when the user disassembles the support inner core 120, the innermost towel sheet 131 can be located, facilitating subsequent operations of tearing, separating, and taking the towel sheet 131.

[0081] Thus, in this embodiment, by providing a spiral tear mark 10 extending from the edge of the first end 121 to the edge of the second end 122 on the peripheral side wall 123 of the support inner core 120 as an easily separable and disassembled structure of the support inner core 120, it is convenient for the support inner core to be easily separated, disassembled, and taken out from the central hole, realizing a central pull-out type towel sheet pull-out and separation mode, that is, starting from the innermost towel sheet 131 at the central hole 110, tearing and separating the towel sheet 131 from the tearable towel roll 130. The user only needs to purchase a tearable towel roll 100 provided in this embodiment that can be pulled out in different ways to simultaneously realize the side pull-out type and the central pull-out type towel sheet pull-out and separation modes, thereby matching various containers or support utensils, meeting various towel sheet taking requirements, and realizing high versatility of the tearable towel roll.

[0082] As Figure 2 and Figure 3As shown, the end of the tearable mark 10 forms a first acute angle r1 with the edge of the first end 121, and the area where the first acute angle r1 is located is the first starting tear end s1. The end of the tearable mark 10 forms a second acute angle r2 with the edge of the second end 122, and the area where the second acute angle r2 is located is the second starting tear end s2.

[0083] The pull tab 11 is disposed at least at one end of the first starting tear end s1 and the second starting tear end s2. For the case where the pull tab 11 is disposed at only one end, the following preferred design can also be made: When the pull tab 11 is disposed at the first starting tear end s1, the connection position of the innermost towel sheet 131 to the outer peripheral wall of the support inner core 120 can preferably be set at a position close to the second starting tear end s2; when the pull tab 11 is disposed at the second starting tear end s2, the connection position of the innermost towel sheet 131 to the outer peripheral wall of the support inner core 120 can preferably be set at a position close to the first starting tear end s1.

[0084] The support inner core 120 is made of crepe paper, or kraft paper, or core board paper, which can not only meet the requirement of being easily torn and disassembled after the tearable mark 10 is set, but also meet the requirements of the support strength, load-bearing capacity and rotation of the tearable towel roll 130. Preferably, the wall thickness of the peripheral side wall 123 of the support inner core 120 is 0.5 mm - 3 mm, the size of the tearable towel roll 130 is 30 cm * 30 cm, 180 GSM, the specification is 75 pieces / roll, and the net weight is 1.215 kg. It should be noted that the wall thickness of the peripheral side wall 123 of the support inner core 120 is not limited to being equal in thickness for each part. For example, the part where the tearable mark 10 is located is relatively thin; again, in some embodiments, the support inner core 120 is formed by spirally winding partially overlapping paper materials, so the overlapping part can be relatively thick.

[0085] Preferably, the height of the support inner core 120 is the same as the height of the tearable towel roll 130 to ensure that the support force received by the tearable towel roll 130 in the axial direction is relatively balanced, and when it is placed vertically, the end is supported by the support inner core 120, and it is not easily squeezed and deformed, fuzzed or damaged.

[0086] Embodiment 2:

[0087] As Figures 5 to 8 shown, the tearable towel roll 200 that can be pulled in different ways provided in this embodiment includes a central hole 210, a cylindrical support inner core 220 disposed in the central hole 210, and a tearable towel roll 230 wound around the outer periphery of the support inner core 220. The tearable towel roll 230 includes a plurality of towel sheets 231 that are connected end to end and can be separated one by one. Similar to Embodiment 1, the tearable towel roll 200 that can be pulled in different ways provided in this embodiment can at least achieve a side-pull type towel sheet pulling and separating mode.

[0088] The supporting inner core 220 includes a peripheral side wall 223, a first end 221, and a second end 222. A tearable band 20 is provided on the peripheral side wall 223, extending from the edge of the first end 221 to the edge of the second end 222. The tearable band 20 can be separated from the peripheral side wall 223, so that the supporting inner core 220 and the towel sheet 231 wound on the inner side of the tearable towel roll 230 can be peeled off and taken out from the central hole 210.

[0089] The tearable connection between the tearable band 20 and the peripheral side wall 223 can be a single dotted line type, a double dotted line type, a herringbone line type, etc., which are more common in the prior art and are not limited in the present invention.

[0090] like Figure 5 and Figure 6 As shown, a pull tab 21 is provided on at least one end of the tearable strip 20. The provision of the pull tab 21 can facilitate the user to quickly find the end of the tearable strip 20, and with the help of the pull tab 21, the tearable strip 20 can be easily torn away from the peripheral side wall 223 and separated from the peripheral side wall 223.

[0091] Therefore, the present embodiment realizes the central pull-out towel sheet separation mode by providing the tearable band 20 extending from the edge of the first end 221 to the edge of the second end 222 on the peripheral side wall 223 of the support inner core 220 as a structure for easy separation and disassembly of the support inner core 220. After the tearable band 20 is separated from the peripheral side wall 223, the peripheral side wall 223 of the support inner core 220 is no longer a complete and continuous cylinder, so that the tearable towel roll 230 can be easily taken out from the central hole 210. Then, the user can tear the towel sheet 231 from the tearable towel roll 230 from the central hole 210, starting from the innermost towel sheet 231.

[0092] The user only needs to purchase a tearable towel roll 200 that can be pulled in different ways provided by the present embodiment, and can simultaneously realize the side-pull type and the center-pull type towel sheet pulling and separation modes, thereby matching a variety of containers or supporting utensils, meeting a variety of towel sheet retrieval needs, and realizing the high versatility of the tearable towel roll.

[0093] like Figure 8 As shown, the innermost towel 231 of the tearable towel roll 230 is adhered to at least a portion of the outer peripheral wall of the supporting inner core 220 and is not connected to the tearable tape 20. When the supporting inner core 220 is taken out from the central hole, the innermost towel piece 231 is taken out, so that the user can locate the innermost towel piece 231 while disassembling the supporting inner core 220, which is convenient for the subsequent tearing, separation, and use operations of the towel piece 231.

[0094] like Figure 5 and Figure 6As shown, in this embodiment, a tearable strip 20 is provided on the peripheral sidewall 223. The tearable strip 20 spirally extends from the edge of the first end 221 to the edge of the second end 222. After the tearable strip 20 is separated, the peripheral sidewall 223 of the remaining support inner core 220 is also spiral and can be easily taken out. Preferably, the width of the tearable strip 20 is 3 mm - 10 mm.

[0095] Embodiment Three:

[0096] As Figures 9 to 10 shown is a tearable towel roll 300 that can be pulled in different ways provided in this embodiment. In terms of other structures, it is the same as Embodiment Two, except that two symmetrically arranged tearable strips 30 are provided on the peripheral sidewall 323 of the support inner core 320. The tearable strips 30 extend along the axial direction of the support inner core 320 and are in a wavy line shape. After the user tears the two tearable strips 30 and separates them from the peripheral sidewall 323, the peripheral sidewall 323 of the support inner core 320 becomes two independent and separated parts, so that it can be easily taken out.

[0097] In other embodiments, the tearable strip 30 can also be in a straight line shape or a broken line shape, and the number can be set to two or more, which can be selected and adjusted according to the diameter and height of the support inner core 320. Of course, only one tearable strip 30 can also be provided. However, compared with the spiral tearable strip 20 in Embodiment Two, the tearable strip 30 in this embodiment extends along the axial direction of the support inner core 320 and does not penetrate the circumferential direction of the support inner core 320. Therefore, setting two or more tearable strips 30 is more conducive to the separation of the peripheral sidewall 323.

[0098] Embodiment Four:

[0099] As Figures 11 to 14 shown is a tearable towel roll 400 that can be pulled in different ways provided in this embodiment, including a central hole 410, a cylindrical support inner core 420 arranged in the central hole 410, and a tearable towel roll 430 wound around the outer periphery of the support inner core 420. The tearable towel roll 430 includes a plurality of towel sheets 431 that are connected end to end and can be separated one by one. Similar to Embodiment One and Two, the tearable towel roll 400 provided in this embodiment can at least achieve a side-pull type towel sheet pulling and separating mode.

[0100] The supporting inner core 420 includes a peripheral side wall 423, a first end 421, and a second end 422. A spiral double-layer separation tape 40 extending from the edge of the first end 421 to the edge of the second end 422 is provided on the peripheral side wall 423. The inner layer of the double-layer separation tape 40 is a spiral tearable tape 41, and the tearable tape 41 can be separated from the peripheral side wall 423 to expose the spiral tearable mark 42 provided on the outer layer. The supporting inner core 420 can be torn and disassembled at any end along the tearable mark 42, and can be peeled off from the towel sheet 431 wound on the inner side of the tearable towel roll 430 by inner rotation, and taken out from the central hole 410.

[0101] It should be understood that the double-layer separation tape 40, as the name implies, has a double-layer structure, with an inner layer and an outer layer, wherein the inner layer is close to the inner peripheral wall of the peripheral side wall 423, and the outer layer is close to the outer peripheral wall of the peripheral side wall 423. The inner layer of the double-layer separation tape 40 is a tearable tape 41, and the connection structure between the tearable tape 41 and the peripheral side wall 423 is shown in Example 2. When the tearable tape 41 is separated from the peripheral side wall 423, the double-layer separation tape 40 loses the inner layer and only the outer layer remains, so a spiral groove 43 extending from the edge of the first end 421 to the edge of the second end 422 is formed on the peripheral side wall 423, and the tearable mark 42 is exposed from the inner peripheral wall of the peripheral side wall 423 through the groove 43.

[0102] Therefore, this embodiment realizes a center-pull-type towel sheet pulling and separation mode by setting a double-layer separation belt 40 extending from the edge of the first end 421 to the edge of the second end 422 on the peripheral side wall 423 of the supporting inner core 420 as a structure that is easy to separate and disassemble the supporting inner core 220.

[0103] Different from the first and second embodiments, the separation and disassembly operation of the support inner core 420 is performed in two steps: the first step is to separate the inner layer of the double-layer separation tape 40, that is, the tearable tape 41, from the peripheral side wall 423. At this time, the double-layer separation tape 40 area becomes thinner. The second step is to tear and disassemble the support inner core 420 along the tearable mark 42 of the outer layer of the double-layer separation tape 40 and take it out. This design of the double-layer separation tape 40 structure is suitable for the case where the support inner core 420 is relatively thick.

[0104] Similarly, the user only needs to purchase a tearable towel roll 400 provided in this embodiment that can be pulled in different ways to simultaneously achieve side-pull and center-pull towel sheet pulling and separation modes, thereby matching a variety of containers or supporting utensils, meeting a variety of towel sheet retrieval needs, and achieving the high versatility of the tearable towel roll.

[0105] like Figure 11 and Figure 12As shown, a pull tab 44 is provided at at least one end of the tearable strip 41. By means of the pull tab 44, the tearable strip 41 can be easily torn relative to the peripheral side wall 423 and separated from the peripheral side wall 423. After the tearable strip 41 is separated, the user can easily find the starting tear end of the tearable mark 42 through the groove 43, and can conveniently tear the tearable mark 42 through the step structure formed between the peripheral side wall 423 and the groove 43.

[0106] As Figure 14 shown, the innermost towel sheet 431 of the tearable towel roll 430 is adhered to at least a part of the outer peripheral wall of the support inner core 420. When the support inner core 420 is taken out from the central hole 410, the innermost towel sheet 431 is taken out, so that when the user disassembles the support inner core 420, the innermost towel sheet 431 can be located, facilitating subsequent operations of tearing, separating, and taking the towel sheet 431.

[0107] Preferably, the width of the tearable strip 41 is 3 mm - 10 mm, and the wall thickness of the tearable strip 41 is 1 / 2 - 3 / 4 of the wall thickness of the peripheral side wall 423 of the support inner core 420, so as to balance the difficulty of tearing and separating the tearable strip 41 and the difficulty of tearing and separating the outer tearable mark 42.

[0108] Embodiment Five:

[0109] As Figures 15 to 20 shown, the tearable towel roll 500 that can be pulled in different ways provided in this embodiment includes a central hole 510, a cylindrical support inner core 520 disposed in the central hole 510, and a tearable towel roll 530 wound around the outer periphery of the support inner core 520. The tearable towel roll 530 includes a plurality of towel sheets 531 that are connected end to end and can be separated one by one. Similar to Embodiments One to Four, the tearable towel roll 500 that can be pulled in different ways provided in this embodiment can at least achieve a side-pull type towel sheet pulling and separating mode.

[0110] As Figures 17 to 19 shown, the support inner core 520 includes a peripheral side wall 523, which is wound by an inner core blank 50 in a spiral manner. The inner core blank 50 is formed by laminating three structural layers, including an inner blank layer 51, a middle blank layer 52, and an outer blank layer 53. Among them, the middle blank layer 52 is made of an easily tearable material. The inner blank layer 51 and the outer blank layer 53 are laminated in a staggered manner to form a first staggered lamination edge c1 and a second staggered lamination edge c2 on both sides of the inner core blank 50. When the inner core blank 50 is wound in a spiral manner, the first staggered lamination edge c1 coincides with the second staggered lamination edge c2.

[0111] The middle blank layer 52 connects the first misaligned stacked edge c1 and the second misaligned stacked edge c2, and can be torn off from any end of the support inner core 520 to separate the first misaligned stacked edge c1 and the second misaligned stacked edge c2. The support inner core 520 is taken out of the central hole 510 in an inward rotation manner.

[0112] Since then, in this embodiment, the support inner core 520 is formed by winding the inner core blank 50 in a spiral manner. The first misaligned stacked edge c1 and the second misaligned stacked edge c2 are connected by the easily tearable middle blank layer 52. As a structure for easy separation and disassembly of the support inner core 520, the support inner core 520 is torn and disassembled in a spiral shape, and then taken out of the central hole 510 in an inward rotation manner, realizing the central pull-out mode of towel sheet pull-out separation. Immediately, the user can start from the innermost towel sheet 531 at the central hole 510 and tear and separate the towel sheet 531 from the tearable towel roll 530.

[0113] In addition, preferably, the misalignment width between the inner blank layer 51 and the outer blank layer 53 is set to 2 mm. After experimentally testing 2000 support inner cores 520 wound with towels, the middle blank layer 52 at one end of the support inner core 520 can be easily torn and the support inner core 520 can be taken out of the central hole 510 in an inward rotation manner. The defective rate is 0.1%. At this time, the misalignment resistance of the inward rotation and tearing to extract the support inner core 520 can be ignored.

[0114] The user only needs to purchase one tearable towel roll 500 provided in this embodiment that can be pulled in different ways to simultaneously realize the side pull-out and central pull-out modes of towel sheet pull-out separation, so as to match a variety of containers or support utensils, meet the needs of taking various towel sheets, and achieve high versatility of the tearable towel roll.

[0115] The difference from Embodiments 1 to 4 is that the tearable towel roll 500 provided in this embodiment that can be pulled in different ways does not need to process structures such as tearable marks and tearable bands on the peripheral side wall 523 of the support inner core 520. On the basis of ensuring that the support inner core 520 is easily taken out of the central hole 510, the structural strength is further ensured to reliably support the tearable towel roll 530. In particular, the tearable towel roll 530 has a certain weight, and when the support inner core 520 is used as a central support or sleeved on a support shaft and the side pull-out separation mode is adopted, the structural strength of the support inner core 520 provided in this embodiment is the most reliable and firm.

[0116] Such as Figures 17 to 19As shown, in this embodiment, after the inner blank layer 51 and the outer blank layer 53 are stacked in a staggered manner, the inner blank layer 51 of the first staggered stacking edge c1 exceeds the outer blank layer 53 to expose the inner surface of the inner blank layer 51, and the outer blank layer 53 of the second staggered stacking edge c2 exceeds the inner blank layer 51 to expose the inner surface of the outer blank layer 53. Thus, when the inner core blank 50 is wound in a spiral manner, the inner surface of the outer blank layer 53 of the second staggered stacking edge c2 is stacked on the inner surface of the inner blank layer 51 of the first staggered stacking edge c1. Therefore, after the first staggered stacking edge c1 and the second staggered stacking edge c2 are stacked, the surfaces of the outer wall and the inner wall of the peripheral side wall 523 of the supporting inner core 520 formed are relatively flat, and the fitting degree with the central hole 510 of the tearable towel roll 530 is better, and it is not easy to slip out without being disassembled.

[0117] As Figure 19 shown, the first staggered stacking edge c1 and the second staggered stacking edge c2 are stacked to form a spiral seam 54 on each of the inside and outside of the peripheral side wall 523 of the supporting inner core 520. At least one of the spiral seams 54 located on the outer wall of the peripheral side wall 523 or the spiral seams 54 located on the inner wall of the peripheral side wall 523 is a closed seam for enhancing the strength of the supporting inner core 520.

[0118] In this embodiment, the spiral seam 54 located on the outer wall of the peripheral side wall 523 of the supporting inner core 520 is an open seam, and the middle blank layer 52 is exposed from the open seam 54. The spiral seam 54 located on the inner wall of the peripheral side wall 523 of the supporting inner core 520 is a closed seam for enhancing the strength of the supporting inner core 520.

[0119] During implementation, the width by which the inner blank layer 51 of the first staggered stacking edge c1 exceeds the outer blank layer 53 is slightly larger than the width by which the outer blank layer 53 of the second staggered stacking edge c2 exceeds the inner blank layer 51. When the two are stacked, the inner surface of a part of the inner blank layer 51 is exposed at the spiral seam 54 on the outer wall of the peripheral side wall 523 to form an open seam. Since the outer wall of the peripheral side wall 523 is the surface where the supporting inner core 520 contacts the tearable towel roll 530, the open seam can increase the friction between the two and prevent the supporting inner core 520 that has not been disassembled from slipping out of the central hole 510. The inner blank layer 51 covers the spiral seam 54 on the inner wall of the peripheral side wall 523, and even a part of the inner blank layer 51 of the first staggered stacking edge c1 is stacked on the inner blank layer 51 of the second staggered stacking edge c2 to form a closed seam, thereby making up for the defect that the structural strength at the overlapping part of the first staggered stacking edge c1 and the second staggered stacking edge c2 is relatively weak, so as to enhance the strength of the supporting inner core 520 and enable it to reliably support the tearable towel roll 530.

[0120] The inner layer 51 and the outer layer 53 are made of hard paper material to provide sufficient support strength for the inner core 520, and the middle layer 52 is made of easy-tear paper material to facilitate tearing. The inner layer 51 and the outer layer 53 are bonded to both sides of the middle layer 52. The hardness of the inner layer 51 and the outer layer 53 can make the part of the middle layer 52 connected between the first offset stacking edge c1 and the second offset stacking edge c2 easier to tear, so as to facilitate the separation of the first offset stacking edge c1 and the second offset stacking edge c2.

[0121] In addition, preferably, the middle layer 52 is different in color from the inner layer 51 and the outer layer 53 for easy identification. The height of the supporting inner core 520 is consistent with the height of the tearable towel roll 530, which can not only ensure the overall appearance of the towel roll, but also make the tearable towel roll 500 that can be pulled in different ways stand stably, and it is not easy to crush the edge of the tearable towel roll 500 when standing and placed.

[0122] like Figure 15 and Figure 16 As shown, the tearable towel roll provided by the utility model can be pulled in different ways, and can be used as follows Figure 15 The side-pull-type pull-out separation mode shown in the figure can also separate and disassemble the support inner core from the center hole and take it out, using Figure 16 The center-pull separation mode shown can match a variety of containers or supporting appliances such as towel roll hanging shafts, center-pull-out towel boxes, side-pull-out towel boxes (not shown in the figure), etc., to meet various towel sheet retrieval needs, achieve high versatility of the tearable towel roll, and give consumers full choice. They only need to purchase a tearable towel roll that can be pulled in different ways provided by the utility model to freely choose the way of use.
