Description

Technical Field

[0001] This disclosure relates to an absorption product. Background Technology

[0002] Absorbent products are well-known in the field of personal hygiene as products that absorb and retain bodily fluids excreted from the wearer's body. Among absorbent products, women's absorbent products can be divided into regular absorbent products for use during the day when the wearer is highly active, and nighttime absorbent products for use at night when the wearer is less active than during the day. Typically, nighttime absorbent products include absorbent components covering a wider area than regular absorbent products to achieve superior absorbency. Nighttime absorbent products are primarily used when the wearer is lying down (e.g., in a sleeping position).

[0003] However, because conventional nighttime absorbent products have a flat surface on the wearer's side, bodily fluids may leak through the gluteal fold towards the outside of the absorbent product near the waist when the wearer lies down. Furthermore, changes in posture during sleep, such as tossing and turning, can cause deformation of the absorbent components. In this case, bodily fluids may also leak towards the outside of the absorbent product. Summary of the Invention

[0004] The embodiments disclosed herein improve upon or resolve at least some of the problems of conventional nighttime absorbent products. To this end, several embodiments provide an absorbent product comprising a second absorbent core having a three-dimensional shape.

[0005] An embodiment of one aspect of this disclosure relates to an absorbent product. The absorbent product according to an exemplary embodiment includes a top sheet facing the body, a bottom sheet facing clothing, an absorbent member disposed between the top sheet and the bottom sheet, and at least one channel portion formed by compressing the top sheet, the bottom sheet, and the absorbent member. The absorbent member includes: an absorbent body extending longitudinally from the front to the rear of the body and having a predetermined thickness; a first absorbent core disposed at a location where bodily fluids are drained from the body and formed to be thicker than the absorbent body; and a second absorbent core disposed rearwardly separate from the first absorbent core and having a three-dimensional shape formed to be thicker than the absorbent body, and configured such that its width increases from the front to the rear in a transverse direction perpendicular to the longitudinal direction. The at least one channel portion includes a pair of first channels adjacent to and extending along both sides of the second absorbent core.

[0006] In one embodiment, the second absorbent core may have a generally triangular shape as seen in the plan view.

[0007] In one embodiment, at least one channel portion may further include a pair of second channels extending between the first absorbent core and the second absorbent core and adjacent to both sides of the pair of first channels.

[0008] In one implementation, each of the pair of second channels may be separated from each of the pair of first channels in the lateral direction.

[0009] In one implementation, the distance between the first channel and the second channel can be greater than 5 mm and less than 20 mm.

[0010] In one embodiment, at least one channel portion may further include a third channel adjacent to the rear end of the second absorber core and extending in a lateral direction.

[0011] In one embodiment, at least one channel portion may further include a fourth channel that is separated from the third channel in the longitudinal direction and extends in the transverse direction.

[0012] In one embodiment, the absorbent component can be integrally manufactured using a molding apparatus having the shape of an absorbent body, a first absorbent core, and a second absorbent core.

[0013] In one embodiment, the separation distance from the center of the absorbent product to the front end of the second absorbent core in the longitudinal direction can be greater than or equal to 10 mm and less than or equal to 100 m.

[0014] In one embodiment, the separation distance from the center of the absorbent product to the front end of the second absorbent core in the longitudinal direction can be greater than or equal to 60 mm and less than or equal to 90 mm.

[0015] In one embodiment, the width at the front end of the second absorbent core in the transverse direction can be greater than or equal to 5 mm and less than or equal to 30 mm, and the width at the rear end of the second absorbent core in the transverse direction can be greater than or equal to 30 mm and less than or equal to 100 mm.

[0016] In one embodiment, the width at the front end of the second absorbent core in the transverse direction can be greater than or equal to 10 mm and less than or equal to 20 mm, and the width at the rear end of the second absorbent core in the transverse direction can be greater than or equal to 40 mm and less than or equal to 60 mm.

[0017] In one embodiment, the length of the second absorbent core in the longitudinal direction can be greater than or equal to 30 mm and less than or equal to 100 mm.

[0018] In one embodiment, the length of the second absorbent core in the longitudinal direction can be greater than or equal to 60 mm and less than or equal to 90 mm.

[0019] The thickness of the second absorbent core can be greater than or equal to 1.3 times and less than or equal to 2.0 times the thickness of the absorbent body.

[0020] In one embodiment, the thickness of the second absorbent core can be greater than or equal to 1.5 times and less than or equal to 1.8 times the thickness of the absorbent body.

[0021] In one embodiment, the distance between the second absorber core and the first channel may be greater than or equal to 0 mm and less than or equal to 10 mm.

[0022] In one embodiment, the distance between the second absorber core and the first channel may be greater than or equal to 0 mm and less than or equal to 2 mm.

[0023] According to one embodiment, the absorbent product is configured such that, because the second absorbent core has a three-dimensional shape that is thicker than the absorbent body and is configured such that its width increases from front to back, the second absorbent core of the absorbent member is in close contact with the wearer's buttock crease. Therefore, the distance between the absorbent product and the buttock crease can be minimized. Thus, even when the wearer is lying down, bodily fluids discharged from the wearer's body can be effectively prevented from flowing through the buttock crease. Attached Figure Description

[0037] Embodiments of this disclosure are described. In the accompanying drawings, identical or corresponding parts are assigned the same reference numerals. Furthermore, redundant descriptions of identical or corresponding parts may be omitted in the following description of the embodiments. However, the omission of descriptions of parts is not intended to imply that such parts are not included in the embodiments.

[0038] Figure 1 This is an exploded perspective view illustrating an absorption product according to one embodiment of the present disclosure. Figure 2 yes Figure 1 A plan view of the illustrated absorbent product.

[0039] like Figure 1 and Figure 2 As shown, an absorbent product (100) according to one embodiment of the present disclosure includes a top sheet (110), a bottom sheet (120), an absorbent member (130), and at least one channel portion (140) (hereinafter referred to as the channel portion).

[0040] The top sheet (110) faces the wearer's body and defines the body-facing surface of the absorbent product (100). The top sheet (110) is made of a liquid-permeable material, allowing bodily fluids excreted from the body (hereinafter referred to as bodily excretions) to pass through. The top sheet (110) guides the bodily excretions away from the wearer's body toward the absorbent member (130).

[0041] In various embodiments, the top sheet (110) may consist of a single layer of material or multiple layers of laminated materials. The top sheet (110) may be made of any material, such as one or more woven sheets, one or more fibrous nonwoven sheets, one or more perforated films (such as blown or extruded films, which may be single-layered or multi-layered), one or more foam sheets (such as open-cell or closed-cell foam in the form of a mesh), coated nonwoven sheets, or any combination of these materials. Such combinations may be adhesively, thermally, or ultrasonically laminated into a uniform planar sheet structure to form the top sheet (110).

[0042] In various embodiments, the top sheet (110) may be composed of various nonwoven fiber webs, such as meltblown fiber webs, spunbond fiber webs, hydroentangled fiber webs, or hot-air bonded carded fiber webs. Examples of preferred materials for the top sheet (110) may include natural fiber webs (such as cotton), rayon, hydroentangled fiber webs, bonded carded fiber webs of polyester, polypropylene, polyethylene, nylon, or other heat-bonded fibers (such as bicomponent fibers), copolymers of polyolefins, polypropylene, and polyethylene, linear low-density polyethylene, and aliphatic esters such as polylactic acid. However, the top sheet (110) is not limited to such materials.

[0043] In various embodiments, the top sheet (110) may include multiple perforations formed to allow bodily effluent to more easily pass through into the absorbent member (130). The multiple perforations may be arranged randomly or uniformly throughout the top sheet (110). The size, shape, diameter, and number of perforations may vary to suit the specific needs of the absorbent product (100).

[0044] In various embodiments, the top sheet (110) may be at least partially hydrophilic. In various embodiments, a portion of the top sheet (110) may be hydrophilic, and the remaining portion of the top sheet (110) may be hydrophobic. In various embodiments, the hydrophobic portion of the top sheet (110) may be an inherently hydrophobic material or a material treated with a hydrophobic coating.

[0045] The backing sheet (120) faces the clothing and defines the clothing-facing surface of the absorbent product (100). The backing sheet (120) is made of a liquid-impermeable material to prevent bodily fluids absorbed into the absorbent member (130) from passing through. The backing sheet (120) may be configured to allow air or vapor to pass through the absorbent product (100) while blocking liquid passage. The backing sheet (120) prevents bodily fluids from leaking out of the absorbent product (100) and prevents wetting of items such as sheets and clothing.

[0046] In various embodiments, the film (120) may consist of a single layer or multiple layers. The film (120) may be made of a hydrophobic nonwoven material with moisture-barrier properties, such as a polyolefin film, a polyethylene film, a polypropylene film, or a nonwoven laminate. An example of a hydrophobic nonwoven material may be a four-layer laminate consisting of spunbond-meltblown-meltblown-spunbond.

[0047] An absorbent member (130) is disposed between a top sheet (110) and a bottom sheet (120). The top sheet (110) and the bottom sheet (120) are bonded and sealed to the outer edge of the absorbent member (130). The absorbent member (130) absorbs and retains bodily fluids that permeate through the top sheet (110). The absorbent member (130) is required to be compressible, conformal, and non-irritating to the wearer's skin. For example, the absorbent member (130) may be manufactured using fluff pulp or fluff pulp mixed with superabsorbent particles. Furthermore, the absorbent member (130) may consist of a single layer or multiple layers laminated together.

[0048] Figure 3 yes Figure 1 A perspective view of the illustrated absorber component.

[0049] like Figure 3 As shown, the absorbent component (130) includes an absorbent body (131), a first absorbent core (132), and a second absorbent core (133). The absorbent body (131) extends from the front to the rear in the longitudinal direction (MD) and has a predetermined thickness. Here, the longitudinal direction (MD) can be understood as the machine direction in which the absorbent product (100) is produced, and the transverse direction (CD) can be understood as the direction that crosses the machine direction and is perpendicular to the machine direction. The planar area of ​​the absorbent body (131) is smaller than the planar areas of the top sheet (110) and the bottom sheet (120).

[0050] A first absorbent core (132) is positioned at the location where bodily fluids are discharged from the body and is formed to be thicker than the absorbent body (131). Here, the location where bodily fluids (i.e., bodily excretions) are discharged from the body can be the female reproductive organs that discharge menstrual blood. The first absorbent core (132) extends in the longitudinal direction (MD). An opening (132a) for retaining bodily excretions can be formed at the center of the first absorbent core (132).

[0051] The second absorbent core (133) is positioned separately from the first absorbent core (132) in a rearward direction. The second absorbent core (133) has a three-dimensional shape that is thicker than the absorbent body (131) and is configured such that its width increases from front to back in a transverse direction (CD) perpendicular to the longitudinal direction (MD). The first absorbent core (132) and the second absorbent core (133) may be configured to have the same thickness. When the wearer wears the absorbent product (100), the second absorbent core (133) with its three-dimensional shape is positioned to make close contact with the gap between the buttocks (hereinafter referred to as the buttock crease), so that the distance between the absorbent product (100) and the buttock crease can be minimized. Therefore, even when the wearer is lying down, bodily fluids can be prevented from leaking near the waist through the buttock crease.

[0052] The channel portion (140) is formed by compressing the top sheet (110), the bottom sheet (120), and the absorbent member (130). In the following description, the channel portion (140) refers to the recessed portion in which each member is compressed, but when the channel portion (140) is formed discontinuously, the channel portion may refer to the embossing as an uncompressed protruding portion. The channel portion (140) includes a pair of first channels (141) that extend outward in the transverse direction (CD) near both sides of the second absorbent core (133). The pair of first channels (141) are disposed on both sides of the second absorbent core (133) to prevent some material of the second absorbent core (133) from moving to the sides, thereby maintaining the three-dimensional shape of the second absorbent core (133). Since the pair of first channels (141) are mirror-symmetrical with respect to the longitudinal axis (LA), which extends in the transverse direction (CD) at the center in the longitudinal direction (MD), only one first channel is described in the following description. The first channel (141) can be discontinuously arranged on both sides of the second absorbent core (133) in the longitudinal direction (MD) to form an embossed pattern. Therefore, when the first channel (141) is formed discontinuously in the longitudinal direction (MD), it is possible to prevent the absorbent member (130) from hardening around the first channel (141). Therefore, it is possible to make the absorbent product (100) conform to the wearer's body with a curved shape (e.g., the buttocks).

[0053] In one embodiment, the channel portion (140) may include one or more channels (140a) formed by compressing the top sheet (110), the bottom sheet (120) and the absorbent member (130) around the first absorbent core (132).

[0054] In one embodiment, the second absorbent core (133) may have a generally triangular shape as seen in the plan view. For example, the second absorbent core (133) may have a generally triangular shape with a narrow width (W1) at the front end and a wide width (W2) at the rear end, and is configured such that the width increases from the front end to the rear end. Examples of the generally triangular shape may include triangles with angled or rounded shapes near the apex. Since the three-dimensional shape of the second absorbent core (133) corresponds to the three-dimensional shape of the region extending from the gluteal cleft to the waist, the gluteal cleft is filled with at least a portion of the second absorbent core (133). Therefore, the absorbent product (100) is able to come into close contact with the wearer's body. Thus, it is possible to effectively prevent bodily fluids from leaking along the gluteal cleft when the wearer is lying down.

[0055] In one embodiment, the channel portion (140) may further include a pair of second channels (142) extending between the first absorbent core (132) and the second absorbent core (133) and adjacent to both sides of the pair of first channels (141). Since the pair of second channels (142) are mirror-symmetrical with respect to the longitudinal axis (LA), only one second channel (142) is described in the following description. A portion of the second channel (142) in the longitudinal direction (MD) extends between the first absorbent core (132) and the second absorbent core (133) in the longitudinal direction (MD), and the remaining portion of the second channel (142) in the longitudinal direction (MD) extends adjacent to the first channel (141) in the longitudinal direction (MD). That is, in the longitudinal direction (MD), the second channel (142) at least partially overlaps with the first channel (141). The second channel (142) serves to prevent wrinkling of the absorbent body (131) and / or the top sheet (110) due to the three-dimensional shape of both sides of the second absorbent core (133). The second channel (142) can be arranged discontinuously along the longitudinal direction (MD) to form an embossed pattern. Therefore, when the second channel (142) is formed discontinuously along the longitudinal direction (MD), it is possible to prevent the absorbent member (130) from hardening around the second channel (142) while maintaining the function of the second channel (142), i.e., preventing wrinkling of the absorbent body (131) and / or the top sheet (110). Thus, the absorbent product (100) can come into close contact with the wearer's body (e.g., the perineum) which has a curved shape.

[0056] In one embodiment, each of the pair of second channels (142) is separable from each of the pair of first channels (141) in the lateral direction (CD). In the region where the first channel (141) and the second channel (142) overlap, the second channel (142) is positioned laterally (CD) on the outside of the first channel (141). The front end of the second channel (142) is separable from the first absorbent core (132) in the longitudinal direction (MD).

[0057] Figure 4 yes Figure 2 The illustrated plan view of the absorbent product shows the dimensions.

[0058] like Figure 4 As shown, in one embodiment, the distance (G1) between the first channel (141) and the second channel (142) can be greater than 5 mm and less than 20 mm. When the distance (G1) between the first channel (141) and the second channel (142) is less than or equal to 5 mm, the first channel (141) and the second channel (142) are positioned too close to each other, and the absorbent member (130) may harden in the overlapping area of ​​the first channel (141) and the second channel (142). Therefore, the absorbent product (100) may not be in close contact with the wearer's body. When the distance between the first channel (141) and the second channel (142) is greater than or equal to 20 mm, the first channel (141) and the second channel (142) are positioned too far apart from each other, and the effect of preventing wrinkling of the absorbent body (131) and / or the top sheet (110) may be reduced.

[0059] In one embodiment, the channel portion (140) may further include a third channel (143) adjacent to the rear end of the second absorbent core (133) and extending in the transverse direction (CD). The third channel (143) may extend in a curved shape in the transverse direction (CD) to correspond to the shape of the rear end of the second absorbent core (133). The third channel (143) is disposed at the rear end of the second absorbent core (133) to prevent some material of the second absorbent core (133) from moving backward, thereby maintaining the three-dimensional shape of the second absorbent core (133). The third channel (143) may be formed continuously or discontinuously in the transverse direction (CD).

[0060] In one embodiment, the channel portion (140) may further include a fourth channel (144) that is separated from the third channel in the longitudinal direction (MD) and extends in the transverse direction (CD). The fourth channel (144) may extend in a curved shape in the transverse direction (CD) to correspond to the shape of the rear end of the second absorbent core (133). The fourth channel (144) serves to prevent wrinkling of the absorbent body (131) and / or the top sheet (110) due to the three-dimensional shape of the rear end of the second absorbent core (133). The fourth channel (144) may be formed continuously or discontinuously in the transverse direction (CD).

[0061] In one embodiment, the absorbent member (130) can be integrally manufactured by a molding apparatus having the shape of an absorbent body (131), a first absorbent core (132), and a second absorbent core (133). For example, the molding apparatus can be configured to have a molding cylinder configured to have the shape of the absorbent body (131), the first absorbent core (132), and the second absorbent core (133) and to rotate. The absorbent body (131), the first absorbent core (132), and the second absorbent core (133) constituting the absorbent member (130) can be formed of the same material. By injecting the material of the absorbent member (130) (e.g., fluff pulp and / or superabsorbent material) into the molding cylinder and conveying it by a conveying device, an absorbent member (130) having a three-dimensional shape in which the first absorbent core (132) and the second absorbent core (133) protrude from the absorbent body (131) can be manufactured. Although the absorbent component (130) has a three-dimensional shape in which the first absorbent core (132) and the second absorbent core (133) protrude from the absorbent body (131), the overall productivity of the absorbent product (100) can be improved because the absorbent component (130) can be manufactured integrally in a single process.

[0062] In one embodiment, the separation distance (L1) in the longitudinal direction (MD) from the center (C) of the absorbent product (100) to the front end of the second absorbent core (133) can be greater than or equal to 10 mm and less than or equal to 100 mm. When the separation distance (L1) between the center of the absorbent product (100) and the second absorbent core (133) is less than 10 mm, the second absorbent core (133) is positioned excessively forward and may not be accurately positioned in the gluteal cleft. When the separation distance (L1) between the center (C) of the absorbent product (100) and the second absorbent core (133) is greater than 100 mm, the second absorbent core (133) is positioned excessively backward and may not be accurately positioned in the gluteal cleft. In a preferred embodiment, the separation distance (L1) in the longitudinal direction (MD) from the center (C) of the absorbent product (100) to the front end of the second absorbent core (133) can be greater than or equal to 60 mm and less than or equal to 90 mm. By setting the separation distance (L1) between the center (C) of the absorbent product (100) and the second absorbent core (133) to be greater than or equal to 60 mm and less than or equal to 90 mm, the second absorbent core (133) can be positioned more accurately in the gluteal cleft.

[0063] In one embodiment, the width (W1) at the front end of the second absorbent core (133) along the transverse direction (CD) can be greater than or equal to 5 mm and less than or equal to 30 mm, and the width (W2) at the rear end of the second absorbent core (133) along the transverse direction (CD) can be greater than or equal to 30 mm and less than or equal to 100 mm. When the width (W1) at the front end of the second absorbent core (133) is less than 5 mm, the width (W1) of the second absorbent core (133) becomes too narrow, and it may be difficult to maintain the three-dimensional shape of the second absorbent core (133). When the width (W1) at the front end of the second absorbent core (133) is greater than 30 mm, the width (W1) of the second absorbent core (133) becomes too wide, and the buttock crease may not be filled by the front end of the second absorbent core (133). When the width (W2) at the rear end of the second absorbent core (133) is less than 30 mm, the width (W2) of the second absorbent core (133) becomes too narrow, and the rear end of the second absorbent core (133) may not cover the area extending from the buttocks to the waist. When the width (W2) at the rear end of the second absorbent core (133) is greater than 100 mm, the width of the second absorbent core (133) becomes too wide, and the area extending from the buttocks to the waist may not be filled by the rear end of the second absorbent core (133). In a preferred embodiment, the width (W1) at the front end of the second absorbent core (133) in the transverse direction (CD) may be greater than or equal to 10 mm and less than or equal to 20 mm, and the width (W2) at the rear end of the second absorbent core (133) in the transverse direction (CD) may be greater than or equal to 40 mm and less than or equal to 60 mm. By setting the width (W1) at the front end of the second absorbent core (133) to be greater than or equal to 10 mm and less than or equal to 20 mm, and setting the width (W2) at the rear end of the second absorbent core (133) to be greater than or equal to 40 mm and less than or equal to 60 mm, the gluteal cleft and the area extending from the gluteal cleft to the waist can be filled by the second absorbent core (133), thereby making the second absorbent core (133) more closely contact.

[0064] In one embodiment, the length (L2) of the second absorbent core (133) along the longitudinal direction (MD) can be greater than or equal to 30 mm and less than or equal to 100 mm. When the length (L2) of the second absorbent core (133) is less than 30 mm, the length (L2) of the second absorbent core (133) becomes too short, and the second absorbent core (133) may not fully cover the gluteal fold and the area extending from the gluteal fold to the waist. When the length (L2) of the second absorbent core (133) is greater than 100 mm, the length (L2) of the second absorbent core (133) becomes too long, and the second absorbent core (133) may be positioned further away from the front of the gluteal fold and the back of the waist. Therefore, the wearing comfort of the absorbent product (100) may be compromised. In a preferred embodiment, the length (L2) of the second absorbent core (133) along the longitudinal direction (MD) can be greater than or equal to 60 mm and less than or equal to 90 mm. By setting the length (L2) of the second absorbent core (133) to be greater than or equal to 60 mm and less than or equal to 90 mm, the second absorbent core (133) can be properly positioned in the gluteal cleft and the area extending from the gluteal cleft to the waist.

[0065] Figure 5 It is along Figure 1 The partial cross-sectional view shown is taken by the VV line. Figure 6 It is along Figure 1 The partial sectional view shown is taken along line VI-VI.

[0066] like Figure 5 and Figure 6As shown, in one embodiment, the thickness (T2) of the second absorbent core (133) can be greater than or equal to 1.3 times and less than or equal to 2.0 times the thickness (T1) of the absorbent body (131). When the thickness (T2) of the second absorbent core (133) is less than 1.3 times the thickness (T1) of the absorbent body (131), the thickness (T2) of the second absorbent core (133) is too thin, and the buttock crease may not be adequately filled by the second absorbent core (133). Therefore, the second absorbent core (133) may not be in close contact with the buttock crease. When the thickness (T2) of the second absorbent core (133) is greater than 2.0 times the thickness (T1) of the absorbent body (131), the thickness (T2) of the second absorbent core (133) is too thick, and the buttock crease may be overfilled by the second absorbent core (133), causing the absorbent product (100) to separate from the buttocks. Therefore, the absorbent product (100) may not be in close contact with the buttocks. Furthermore, the top sheet (110) may wrinkle due to the difference between the thickness (T2) of the second absorbent core (133) and the thickness (T1) of the absorbent body (131). In a preferred embodiment, the thickness (T2) of the second absorbent core (133) can be greater than or equal to 1.5 times and less than or equal to 1.8 times the thickness (T1) of the absorbent body (131). By setting the thickness (T2) of the second absorbent core (133) to be greater than or equal to 1.5 times and less than or equal to 1.8 times the thickness (T1) of the absorbent body (131), the second absorbent core (133) and the absorbent product (100) including the second absorbent core (133) can make close contact with the body in an appropriate manner.

[0067] In one embodiment, the distance (G2) between the second absorbent core (133) and the first channel (141) can be greater than or equal to and less than or equal to 10 mm. When the distance (G2) between the second absorbent core (133) and the first channel (141) is greater than 10 mm, the first channel (141) is positioned away from the second absorbent core (133), and this may reduce the effectiveness of the first channel (141) in maintaining the three-dimensional shape of the second absorbent core (133). In a preferred embodiment, the distance (G2) between the second absorbent core (133) and the first channel (141) can be less than or equal to 2 mm. By setting the distance (G2) between the second absorbent core (133) and the first channel (141) to less than or equal to 2 mm, the first channel (141) can more effectively maintain the three-dimensional shape of the second absorbent core (133). In this embodiment, the lower limit of the distance (G2) between the second absorbent core (133) and the first channel (141) can include zero. That is, the first channel (141) can be attached to the second absorber core (133).
