Description

Technical Field

[0001] This utility model relates to the field of hygiene products, and in particular to a wearable hygiene product core and a wearable hygiene product. Background Technology

[0002] Wearable hygiene products are widely used by infants and young children and patients who cannot take care of themselves. The surface of existing wearable hygiene products is smooth, which makes it easy for urine to accumulate on the surface (i.e., the surface layer). The fluffy fabric inside the wearable hygiene product, which can absorb a large amount of urine, cannot be fully utilized, resulting in urine not being easily absorbed and being absorbed slowly. This causes urine to accumulate on the surface layer that is in direct contact with the user's skin, resulting in a poor user experience.

[0003] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a wearable hygiene product core and wearable hygiene products that can increase the amount and speed of urine absorption, thereby improving the hygiene and user experience of wearable hygiene products.

[0005] According to a first aspect of the present invention, a wearable hygiene product core is provided, comprising: a covering fabric including a lower surface, a side surface, and an upper surface of the covering fabric integrally connected to form a receiving cavity inside the covering fabric; at least one absorbent layer disposed within the receiving cavity and located above the lower surface of the covering fabric, the absorbent layer defining a centerline along its length direction, the absorbent layer having at least two absorbent layer openings, at least one of the at least two absorbent layer openings being located to the left of the centerline, and at least one of the at least two absorbent layer openings being located on the left side of the centerline. To the right of the center line; and a nonwoven fabric disposed within the receiving cavity and above the at least one absorbent layer; wherein, when the absorbent layer is one layer, the nonwoven fabric is recessed downwards at the position corresponding to the opening of the absorbent layer until it connects to the lower surface of the covering fabric, thereby forming a nonwoven fabric recess in the nonwoven fabric; when the absorbent layer is at least two layers, the nonwoven fabric is recessed downwards at the position corresponding to the opening of the absorbent layer until it connects to the lower surface of the covering fabric or one of the at least two absorbent layers that contacts the lower surface of the covering fabric, thereby forming a nonwoven fabric recess in the nonwoven fabric.

[0006] Preferably, the at least one absorbent layer comprises a first voluminous fabric and / or absorbent cotton.

[0007] Preferably, the openings of the at least two absorbent layers are symmetrical about the centerline.

[0008] Preferably, the absorbent layer opening includes a first portion and a second portion, the included angle between the first portion and the second portion is a predetermined angle, and they intersect at a connecting portion; the portion of the first portion of the absorbent layer opening closer to the connecting portion is closer to the center line than the portion of the first portion of the absorbent layer opening farther from the connecting portion; the portion of the second portion of the absorbent layer opening closer to the connecting portion is closer to the center line than the portion of the second portion of the absorbent layer opening farther from the connecting portion.

[0009] Preferably, the opening of the absorbent layer extends along the length of the absorbent layer.

[0010] Preferably, the opening of the absorbent layer is rectangular.

[0011] Preferably, when the absorbent layer is a single layer, the upper surface of the covering fabric is recessed downwards at the position corresponding to the opening of the absorbent layer until it connects to the lower surface of the covering fabric, thereby forming a nonwoven fabric recess in the nonwoven fabric; when the absorbent layer is at least two layers, the upper surface of the covering fabric is recessed downwards at the position corresponding to the opening of the absorbent layer until it connects to the lower surface of the covering fabric or one of the at least two absorbent layers that contacts the lower surface of the covering fabric, thereby forming a nonwoven fabric recess in the nonwoven fabric.

[0012] According to a second aspect of the present invention, a wearable hygiene product is provided, which is equipped with a wearable hygiene product core as described in the first aspect, wherein the surface layer is disposed on the side of the wearable hygiene product core closer to the skin.

[0013] Preferably, the surface layer is recessed downward at the position corresponding to the opening of the first loose fabric to form a recessed portion of the surface layer.

[0014] Preferably, the wearable hygiene product further includes: a second voile fabric disposed between the surface layer and the core of the wearable hygiene product, and having a second voile fabric opening corresponding to the opening of the first voile fabric, wherein the recessed portion of the surface layer passes through the second voile fabric opening.

[0015] When urine enters the core of a wearable sanitary product, in addition to permeating and spreading from the top surface of the covering fabric into the absorbent layer, the non-woven fabric's recesses guide the urine to the openings in the absorbent layer. The urine then spreads outwards from these openings, allowing the absorbent layer to absorb the urine more effectively. This increases the absorption capacity and speed of the wearable sanitary product's core, thereby improving its hygiene and user experience. Furthermore, each absorbent layer has at least two openings, which increases the flow and absorption speed, fully utilizing the absorbency of the absorbent layer to further enhance the hygiene and user experience of the wearable sanitary product.

[0045] It should be understood that the accompanying drawings are not necessarily drawn to scale, but rather present simplified representations of various features to illustrate the basic principles of this invention. The specific design features disclosed in this invention (including, for example, specific dimensions, orientations, positions, and shapes) will be determined in part by the specific application and environment in which they will be used.

[0046] Throughout these figures, the same reference numerals denote the same or equivalent parts of the present invention. Detailed Implementation

[0047] The present invention will now be described in detail with reference to various embodiments, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. Rather, the present invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit of the present invention and the scope defined by the appended claims.

[0048] When a component is referred to as being "above" or "on top of" another component, the component may be in contact with the other component, or the component may be spaced apart from the other component, or there may be an intermediate component between the component and the other component.

[0049] The top of this utility model is Figure 1 , Figures 2F to 11 At the top, when the wearable hygiene product core is made into a wearable hygiene product and worn on a person, the top is the side closest to the skin.

[0050] The wearable hygiene products mentioned in the embodiments of this utility model include, but are not limited to, baby diapers / pull-up pants, women's sleeping pants, and adult diapers / pull-up pants.

[0051] In this embodiment of the invention, "before" and "after" refer to the front and back of the wearable hygiene product after it has been unfolded.

[0052] The following is combined with Figures 1 to 11 The wearable hygiene product core according to the embodiment of this utility model will be described.

[0053] like Figure 1 and Figure 2A As shown, the wearable hygiene product core of this utility model embodiment includes: a covering fabric 100, at least one absorbent layer, and a non-woven fabric 300.

[0054] The covering fabric 100 includes a lower surface 101, a side surface 102, and an upper surface 103 of the covering fabric that are integrally connected to form a receiving cavity 104 inside the covering fabric 100.

[0055] At least one absorbent layer is disposed within the receiving cavity 104 and above the lower surface 101 of the covering fabric. The absorbent layer defines a center line X along its length direction. The absorbent layer is provided with at least two absorbent layer openings. At least one of the at least two absorbent layer openings is located to the left of the center line X, and at least one of the at least two absorbent layer openings is located to the right of the center line X.

[0056] The nonwoven fabric 300 is disposed within the receiving cavity 104 and is located above at least one absorbent layer.

[0057] When the absorbent layer is a single layer, the nonwoven fabric 300 is recessed downwards at the position of the absorbent layer opening corresponding to the absorbent layer until it connects to the lower surface 101 of the covering fabric, thereby forming a nonwoven fabric recess 301 in the nonwoven fabric 300.

[0058] When there are at least two absorbent layers, the nonwoven fabric 300 is recessed downwards at the position of the absorbent layer opening corresponding to the absorbent layer until it connects to the lower surface 101 of the covering fabric or one of the at least two absorbent layers that contacts the lower surface 101 of the covering fabric, thereby forming a nonwoven fabric recess 301 in the nonwoven fabric 300.

[0059] When urine enters the core of the wearable sanitary product, in addition to penetrating and diffusing from the upper surface 103 of the covering fabric into the absorbent layer (i.e., penetrating and diffusing in the direction of arrow L1), the non-woven fabric recesses 301 of the non-woven fabric 300 can also guide the urine to the opening of the absorbent layer. Then, the urine diffuses outwards from the opening of the absorbent layer (i.e., diffuses in the direction of arrow L2), allowing the absorbent layer to absorb the urine more fully. This increases the amount and speed of urine absorption by the core of the wearable sanitary product, thereby improving the hygiene and user experience of the wearable sanitary product. Furthermore, each absorbent layer has at least two absorbent layer openings, which can increase the flow rate and absorption speed, fully utilizing the absorbency of the absorbent layer, thereby further improving the hygiene and user experience of the wearable sanitary product.

[0060] The nonwoven fabric 300 can be made of spunlace fabric, spunbond fabric, or spunmelt fabric. The type of nonwoven fabric 300 is not limited to these; it can be any form in the prior art, as long as it can achieve the above-mentioned functions.

[0061] It should be noted that all the accompanying drawings in this utility model are only schematic diagrams of the approximate shape of each layer and the approximate positional relationship between the layers. To better distinguish the boundaries between the layers, in Figure 1 , Figures 2F to 8 The diagram illustrates the gaps between the layers, but in the actual product, there are no gaps between the layers.

[0062] In the following embodiments, the absorbent layer is selected from the first loose fabric 201, the first loose fabric 202, or the absorbent cotton 400, and the corresponding absorbent layer openings are the first loose fabric opening 203, the first loose fabric opening 207, and the absorbent cotton opening 401, respectively.

[0063] Example 1

[0064] like Figure 1 As shown, the wearable hygiene product core of this embodiment includes: a covering fabric 100, a first loose fabric 201, and a non-woven fabric 300. In this embodiment, the absorbent layer includes the first loose fabric 201.

[0065] The covering fabric 100 includes a lower surface 101, a side surface 102, and an upper surface 103 of the covering fabric that are integrally connected to form a receiving cavity 104 inside the covering fabric 100.

[0066] like Figure 1 As shown, the first loose fabric 201 is disposed within the receiving cavity 104 and located above the lower surface 101 of the covering fabric, as... Figure 2A As shown, the first tufted fabric 201 defines a center line X along its length direction. The first tufted fabric 201 is provided with two first tufted fabric openings 203. One of the two first tufted fabric openings 203 is located to the left of the center line X, and the other of the two first tufted fabric openings 203 is located to the right of the center line X. Polymer particles are attached to the first tufted fabric 201.

[0067] The nonwoven fabric 300 is disposed within the receiving cavity 104 and is located above the first loose fabric 201.

[0068] The upper surface 103 of the covering fabric and the nonwoven fabric 300 are recessed downwards at the position corresponding to the opening 203 of the first loose fabric until they are connected to the lower surface 101 of the covering fabric, thereby forming a covering fabric recess 105 on the upper surface 103 of the covering fabric and a nonwoven fabric recess 301 on the nonwoven fabric 300.

[0069] When urine enters the core of the wearable sanitary product, in addition to penetrating and diffusing from the upper surface 103 of the covering fabric to the first loose fabric 201 (i.e., penetrating and diffusing in the direction of arrow L1), the recessed portion 105 of the covering fabric 103 and the recessed portion 301 of the nonwoven fabric 300 can also guide the urine to the opening 203 of the first loose fabric. Then, the urine diffuses in all directions from the opening 203 of the first loose fabric (i.e., diffuses in the direction of arrow L2), allowing the polymer particles attached to the first loose fabric 201 to more fully absorb the urine, thereby increasing the amount and speed of urine absorption by the core of the wearable sanitary product. In addition, the first loose fabric opening 203 of the first loose fabric 201 is set to two, which can increase the flow rate and absorption rate, make full use of the water absorption of the polymer particles, and further improve the hygiene and user experience of the wearable sanitary product.

[0070] In an exemplary implementation, such as Figures 2A to 2C As shown, the first loose fabric opening 203 has an even number of openings.

[0071] Of course, in other implementation schemes, such as Figure 2D As shown, the first opening 203 of the voluminous fabric can be set to an odd number, for example, 3.

[0072] In an exemplary implementation, such as Figures 2A to 2DAs shown, at least two first voluminous fabric openings 203 are symmetrical about the center line X.

[0073] In other implementations, the first voile openings 203 on both sides of the center line X can also be asymmetrically arranged.

[0074] Example 2

[0075] like Figure 2A As shown, the first voile fabric opening 203 includes a first voile fabric opening first portion 204 and a first voile fabric opening second portion 205. The included angle between the first voile fabric opening first portion 204 and the first voile fabric opening second portion 205 is a predetermined angle, and they intersect at the connecting portion 206. Figure 1 for Figure 2A Cross-sectional view at point AA. Figure 2F for Figure 2A Cross-sectional view at point BB. Figure 1 and Figure 2A The difference lies in the distance between the recessed parts.

[0076] The portion of the first opening 204 of the first loose fabric near the connecting portion 206 is closer to the center line X than the portion of the first opening 204 of the first loose fabric away from the connecting portion 206.

[0077] The portion of the second part 205 of the first loose fabric opening closer to the connecting part 206 is closer to the center line X than the portion of the second part 205 of the first loose fabric opening further away from the connecting part 206.

[0078] In an exemplary embodiment, the included angle between the first portion 204 of the first voile opening and the second portion 205 of the first voile opening ranges from 10° to 170°.

[0079] In an exemplary embodiment, the distance between the two connecting portions 206 ranges from 3 mm to 120 mm.

[0080] In addition to Embodiment 2, the first loose fabric opening 203 can also extend along the length of the first loose fabric 201 as a whole, for example, Embodiment 3 and Embodiment 4.

[0081] Example 3

[0082] In this embodiment, as Figure 2C and Figure 2D As shown, the first opening 203 of the voluminous fabric is rectangular.

[0083] Example 4

[0084] In this embodiment, as Figure 2E As shown, the first opening 203 of the loose fabric is elliptical.

[0085] Example 5

[0086] like Figure 3A As shown, the wearable hygiene product core of this embodiment includes: a covering fabric 100, a first loose fabric 201, a non-woven fabric 300, and absorbent cotton 400. In this embodiment, the absorbent layer includes the first loose fabric 201 and the absorbent cotton 400.

[0087] The covering fabric 100 includes a lower surface 101, a side surface 102, and an upper surface 103 of the covering fabric that are integrally connected to form a receiving cavity 104 inside the covering fabric 100.

[0088] The first volumized fabric 201 is disposed in the receiving cavity 104 and located above the lower surface 101 of the covering fabric. The first volumized fabric 201 defines a center line X along its length direction. The first volumized fabric 201 is provided with two first volumized fabric openings 203. One of the two first volumized fabric openings 203 is located to the left of the center line X, and the other of the two first volumized fabric openings 203 is located to the right of the center line X. Polymer particles are attached to the first volumized fabric.

[0089] Absorbent cotton 400 is disposed between nonwoven fabric 300 and first voile fabric 201, and has absorbent cotton opening 401. Absorbent cotton 400 is also capable of absorbing urine. Absorbent cotton 400 may be a mixture of fluff pulp and superabsorbent polymer.

[0090] The nonwoven fabric 300 is disposed within the receiving cavity 104 and is located above the first loose fabric 201.

[0091] The upper surface 103 of the covering fabric and the nonwoven fabric 300 are recessed downwards at the position corresponding to the opening 203 of the first loose fabric until they are connected to the lower surface 101 of the covering fabric, thereby forming a covering fabric recess 105 on the upper surface 103 of the covering fabric and a nonwoven fabric recess 301 on the nonwoven fabric 300.

[0092] When urine enters the core of the wearable sanitary product, in addition to penetrating and diffusing from the upper surface 103 of the covering fabric to the first loose fabric 201 (i.e., penetrating and diffusing in the direction of arrow L1), the covering fabric recess 105 of the upper surface 103 of the covering fabric and the non-woven fabric recess 301 of the non-woven fabric 300 can also guide the urine to the absorbent cotton opening 401 and the first loose fabric opening 203. Then, the urine diffuses in all directions at the absorbent cotton opening 401 (i.e., diffuses in the direction of arrow L3), allowing the absorbent cotton 400 to absorb the urine more fully, and diffuses in all directions at the first loose fabric opening 203 (i.e., diffuses in the direction of arrow L2), allowing the polymer particles attached to the first loose fabric 201 to absorb the urine more fully, thereby increasing the amount and speed of urine absorption by the core of the wearable sanitary product.

[0093] Compared to Example 1, Example 5 adds a layer of absorbent cotton 400, which can further increase the absorption capacity and improve the absorption speed.

[0094] Example 6

[0095] like Figure 3B As shown, the wearable hygiene product core of this embodiment includes: a covering fabric 100, a first loose fabric 201, a non-woven fabric 300, and absorbent cotton 400. In this embodiment, the absorbent layer includes the first loose fabric 201 and the absorbent cotton 400.

[0096] The difference between Example 6 and Example 5 is that the absorbent cotton 400 is disposed between the first loose cloth 201 and the lower surface 101 of the covering cloth.

[0097] Example 7

[0098] like Figure 4 As shown, the wearable hygiene product core of this embodiment includes: a covering fabric 100, a first loose fabric 201, a first loose fabric 202, and a non-woven fabric 300. In this embodiment, the absorbent layer includes the first loose fabric 201 and the first loose fabric 202.

[0099] The covering fabric 100 includes a lower surface 101, a side surface 102, and an upper surface 103 of the covering fabric that are integrally connected to form a receiving cavity 104 inside the covering fabric 100.

[0100] The first volumized fabric 201 is disposed in the receiving cavity 104 and located above the lower surface 101 of the covering fabric. The first volumized fabric 201 defines a center line X along its length direction. The first volumized fabric 201 is provided with two first volumized fabric openings 203. One of the two first volumized fabric openings 203 is located to the left of the center line X, and the other of the two first volumized fabric openings 203 is located to the right of the center line X. Polymer particles are attached to the first volumized fabric 201.

[0101] The first tufted cloth 202 is disposed in the receiving cavity 104 and is located above the first tufted cloth 201. The first tufted cloth 202 has a first tufted cloth opening 207 that is the same as the first tufted cloth opening 203, and polymer particles are attached to the first tufted cloth 202.

[0102] The nonwoven fabric 300 is disposed within the receiving cavity 104 and is located above the first loose fabric 202.

[0103] The upper surface 103 of the covering fabric and the nonwoven fabric 300 are recessed downwards at the position corresponding to the opening 203 of the first loose fabric until they are connected to the lower surface 101 of the covering fabric, thereby forming a covering fabric recess 105 on the upper surface 103 of the covering fabric and a nonwoven fabric recess 301 on the nonwoven fabric 300.

[0104] When urine enters the core of the wearable sanitary product, in addition to penetrating and diffusing from the upper surface 103 of the covering fabric to the first loose fabric 201 (i.e., penetrating and diffusing in the direction of arrow L1), the covering fabric recess 105 of the upper surface 103 of the covering fabric and the non-woven fabric recess 301 of the non-woven fabric 300 can also guide the urine to the openings 203 and 207 of the first loose fabric. Then, the urine diffuses in all directions from the openings 203 and 207 of the first loose fabric (i.e., diffuses in the direction of arrow L2), so that the polymer particles attached to the first loose fabric 201 and the first loose fabric 202 can more fully absorb the urine, thereby increasing the amount and speed of urine absorption by the core of the wearable sanitary product.

[0105] In an exemplary embodiment, the width of the first opening 207 of the first tufted fabric 202 is the same as the width of the first opening 203 of the first tufted fabric 201, and the length of the first opening 207 of the first tufted fabric 202 is shorter than the length of the first opening 203 of the first tufted fabric 201, so as to prevent urine from leaking out too quickly and disorderly from front to back at the first opening 203, thereby preventing front and back leakage.

[0106] The relationship between the length of the first loose fabric opening 207 and the length of the first loose fabric opening 203 is not shown in the figure.

[0107] In an exemplary embodiment, the first voile fabric 202 and the first voile fabric 201 have the same size and thickness.

[0108] In an exemplary embodiment, the width of the first voile opening 203 and the first voile opening 207 ranges from 5mm to 70mm, the length of the first voile opening 203 ranges from 40mm to 480mm, and the length of the first voile opening 207 ranges from 50mm to 470mm.

[0109] Example 8

[0110] like Figure 5A As shown, the wearable hygiene product core of this embodiment includes: a covering fabric 100, a first loose fabric 201, a first loose fabric 202, absorbent cotton 400, and a non-woven fabric 300. In this embodiment, the absorbent layer includes the first loose fabric 201, the first loose fabric 202, and the absorbent cotton 400.

[0111] The covering fabric 100 includes a lower surface 101, a side surface 102, and an upper surface 103 of the covering fabric that are integrally connected to form a receiving cavity 104 inside the covering fabric 100.

[0112] The first volumized fabric 201 is disposed in the receiving cavity 104 and located above the lower surface 101 of the covering fabric. The first volumized fabric 201 defines a center line X along its length direction. The first volumized fabric 201 is provided with two first volumized fabric openings 203. One of the two first volumized fabric openings 203 is located to the left of the center line X, and the other of the two first volumized fabric openings 203 is located to the right of the center line X. Polymer particles are attached to the first volumized fabric 201.

[0113] The first tufted cloth 202 is disposed in the receiving cavity 104 and is located above the first tufted cloth 201. The first tufted cloth 202 has a first tufted cloth opening 207 that is the same as the first tufted cloth opening 203, and polymer particles are attached to the first tufted cloth 202.

[0114] Absorbent cotton 400 is disposed between nonwoven fabric 300 and first voile fabric 202, and has absorbent cotton opening 401. Absorbent cotton 400 is also capable of absorbing urine. Absorbent cotton 400 may be a mixture of fluff pulp and superabsorbent polymer.

[0115] The nonwoven fabric 300 is disposed within the receiving cavity 104 and is located above the absorbent cotton 400.

[0116] The upper surface 103 of the covering fabric and the nonwoven fabric 300 are recessed downwards at the position corresponding to the opening 203 of the first loose fabric until they are connected to the lower surface 101 of the covering fabric, thereby forming a covering fabric recess 105 on the upper surface 103 of the covering fabric and a nonwoven fabric recess 301 on the nonwoven fabric 300.

[0117] When urine enters the core of the wearable sanitary product, in addition to penetrating and diffusing from the upper surface 103 of the covering fabric to the first loose fabric 201 (i.e., penetrating and diffusing in the direction of arrow L1), the covering fabric recess 105 of the upper surface 103 of the covering fabric and the non-woven fabric recess 301 of the non-woven fabric 300 can also guide the urine to the absorbent cotton opening 401, the first loose fabric opening 203 and the first loose fabric opening 207. Then the urine diffuses in all directions at the absorbent cotton opening 401 (i.e., diffuses in the direction of arrow L3), so that the absorbent cotton 400 can absorb the urine more fully, and diffuses in all directions at the first loose fabric opening 203 and the first loose fabric opening 207 (i.e., diffuses in the direction of arrow L2), so that the polymer particles attached to the first loose fabric 201 and the first loose fabric 202 can absorb the urine more fully, thereby increasing the amount and speed of urine absorption by the core of the wearable sanitary product.

[0118] Example 9

[0119] like Figure 5BAs shown, the wearable hygiene product core of this embodiment includes: a covering fabric 100, a first loose fabric 201, a first loose fabric 202, absorbent cotton 400, and a non-woven fabric 300. In this embodiment, the absorbent layer includes the first loose fabric 201, the first loose fabric 202, and the absorbent cotton 400.

[0120] The difference between Example 9 and Example 8 is that the absorbent cotton 400 is disposed between the first loose fabric 201 and the first loose fabric 202.

[0121] Example 10

[0122] like Figure 5C As shown, the wearable hygiene product core of this embodiment includes: a covering fabric 100, a first loose fabric 201, a first loose fabric 202, absorbent cotton 400, and a non-woven fabric 300. In this embodiment, the absorbent layer includes the first loose fabric 201, the first loose fabric 202, and the absorbent cotton 400.

[0123] The difference between Example 10 and Example 8 is that the absorbent cotton 400 is disposed between the first loose cloth 201 and the lower surface 101 of the covering cloth.

[0124] The number of layers of voluminous fabric in the core of wearable hygiene products can be adjusted.

[0125] Example 11

[0126] like Figure 6A As shown, the wearable hygiene product core of this embodiment includes: covering fabric 100, first loose fabric 201, first loose fabric 202, absorbent cotton 400 and non-woven fabric 300.

[0127] The difference between Example 11 and Example 8 is that the upper surface 103 of the covering fabric does not completely cover the entire upper surface of the nonwoven fabric 300, but only covers a portion (about half) of the upper surface of the nonwoven fabric 300, and no nonwoven fabric recess is formed.

[0128] This enveloping relationship also applies to... Figure 1 , Figure 2F , Figure 3A , Figure 3B , Figure 4 , Figure 5A , Figure 5B , Figure 5C Examples of implementations.

[0129] Example 12

[0130] like Figure 6B As shown, the wearable hygiene product core of this embodiment includes: covering fabric 100, first loose fabric 201, first loose fabric 202, absorbent cotton 400 and non-woven fabric 300.

[0131] The difference between Example 12 and Example 8 is that the upper surface 103 of the covering fabric does not completely cover the entire upper surface of the nonwoven fabric 300, but only covers the edge part of the upper surface of the nonwoven fabric 300, and does not form a nonwoven fabric recess.

[0132] This enveloping relationship also applies to... Figure 1 , Figure 2F , Figure 3A , Figure 3B , Figure 4 , Figure 5A , Figure 5B , Figure 5C Examples of implementations.

[0133] Example 13

[0134] like Figure 10 As shown, the wearable hygiene product core of this embodiment includes: a covering fabric 100, a first loose fabric 201, a first loose fabric 202, and a non-woven fabric 300. In this embodiment, the absorbent layer includes the first loose fabric 201 and the first loose fabric 202.

[0135] The covering fabric 100 includes a lower surface 101, a side surface 102, and an upper surface 103 of the covering fabric that are integrally connected to form a receiving cavity 104 inside the covering fabric 100.

[0136] The first volumized fabric 202 is disposed within the receiving cavity 104 and located above the lower surface 101 of the covering fabric. The first volumized fabric 202 defines a center line X along its length direction. The first volumized fabric 202 is provided with two first volumized fabric openings 207. One of the two first volumized fabric openings 207 is located to the left of the center line X, and the other of the two first volumized fabric openings 207 is located to the right of the center line X. Polymer particles are attached to the first volumized fabric 202.

[0137] The first loose fabric 201 is disposed in the receiving cavity 104 and is located above the first loose fabric 202 and the lower surface 101 of the covering fabric, and polymer particles are attached to the first loose fabric 201.

[0138] The nonwoven fabric 300 is disposed within the receiving cavity 104 and is located above the first loose fabric 202.

[0139] The upper surface 103 of the covering fabric and the nonwoven fabric 300 are recessed downwards at the position corresponding to the opening 207 of the first loose fabric until they are connected to the first loose fabric 201, thereby forming a covering fabric recess 105 on the upper surface 103 of the covering fabric and a nonwoven fabric recess 301 on the nonwoven fabric 300.

[0140] When urine enters the core of the wearable sanitary product, in addition to penetrating and diffusing from the upper surface 103 of the covering fabric to the first loose fabric 202 (i.e., penetrating and diffusing in the direction of arrow L1), the covering fabric recess 105 of the upper surface 103 of the covering fabric and the non-woven fabric recess 301 of the non-woven fabric 300 can also guide the urine to the opening 207 of the first loose fabric. Then, the urine diffuses in all directions from the opening 207 of the first loose fabric (i.e., diffuses in the direction of arrow L2), so that the polymer particles attached to the first loose fabric 202 can absorb the urine more fully, thereby increasing the amount and speed of urine absorption by the core of the wearable sanitary product.

[0141] Example 14

[0142] like Figure 11 As shown, the wearable hygiene product core of this embodiment includes: a covering fabric 100, a first loose fabric 201, a first loose fabric 202, absorbent cotton 400, and a non-woven fabric 300. In this embodiment, the absorbent layer includes the first loose fabric 201, the first loose fabric 202, and the absorbent cotton 400.

[0143] The difference between Embodiment 14 and Embodiment 8 is that the first loose fabric 201 does not have a first loose fabric opening 203, while the upper surface 103 of the covering fabric and the nonwoven fabric 300 are recessed downwards at the position corresponding to the first loose fabric opening 207 until they are connected to the first loose fabric 201, thereby forming a covering fabric recess 105 on the upper surface 103 of the covering fabric and a nonwoven fabric recess 301 on the nonwoven fabric 300.

[0144] In both Examples 13 and 14, no opening is made in the layer that contacts the lower surface 101 of the covering fabric (i.e., the bottommost layer) of at least two absorbent layers, and the corresponding covering fabric recess 105 and nonwoven fabric recess 301 are connected to this absorbent layer. This applies to variations of any of Examples 5 to 12.

[0145] like Figure 7 As shown, the present invention also provides a wearable hygiene product, which is equipped with a surface layer 500 and the aforementioned wearable hygiene product core, wherein the surface layer 500 is disposed on the side of the wearable hygiene product core that is close to the skin.

[0146] Figure 7 The wearable hygiene product described herein is only an example of the wearable hygiene product core in Example 8; it can also be replaced with the wearable hygiene product cores of Examples 1, 5 to 14. Furthermore, Figure 7 Only the structure of the surface layer and the core of the wearable hygiene product is shown; the entire structure of the wearable hygiene product is not shown.

[0147] In an exemplary implementation, such as Figure 7 and Figure 8 As shown, the surface layer 500 is recessed downwards at the position corresponding to the first open fabric 203 to form a surface layer recess 501. The surface layer 500 is a structure that directly contacts the user's skin.

[0148] In an exemplary implementation, such as Figure 8 As shown, the wearable sanitary product further includes a second voile fabric 600, which is disposed between the surface layer 500 and the core of the wearable sanitary product, and has a second voile fabric opening 601 corresponding to the first voile fabric opening 203. The surface layer recess 501 passes through the second voile fabric opening 601. The second voile fabric 600 can increase the softness of the wearable sanitary product, and the second voile fabric opening 601 allows the surface layer recess 501 to pass through, increasing its absorbency.

[0149] like Figure 9 As shown, polymer particles 700 penetrate downwards from above the first tufted cloth 201 to adhere to the first tufted cloth 201. Some of the polymer particles 700 remain inside the first tufted cloth 201, some remain on the upper surface of the first tufted cloth 201, and some penetrate the first tufted cloth 201 and adhere to the lower surface of the first tufted cloth 201.

[0150] The operation of the wearable hygiene product core of this utility model embodiment will be described below with reference to the accompanying drawings.

[0151] The working process of the wearable hygiene product according to the present invention will be described below with reference to the accompanying drawings.

[0152] The surface layer 500 comes into direct contact with the user's skin.

[0153] The surface layer 500 absorbs urine, among which, in combination with Figure 7 As shown, the surface layer recess 501 of the surface layer 500, the covering fabric recess 105 of the upper surface of the covering fabric 103, and the non-woven fabric recess 301 of the non-woven fabric 300 can also guide urine to the absorbent cotton opening 401, the first loose fabric opening 203, and the first loose fabric opening 203. Then, the urine spreads to the surrounding areas at the absorbent cotton opening 401, the first loose fabric opening 203, and the first loose fabric opening 203, so that the polymer particles attached to the first loose fabric 201 and the first loose fabric 202 can absorb the urine more fully, and the absorbent cotton 400 can absorb the urine more fully, thereby improving the hygiene and user experience of the wearable hygiene products.
