DETAILED DESCRIPTION

[0029] With reference to the drawings, a detailed description of the exemplary embodiments of the absorbent article disclosed in the present application will be given. Although the drawings are provided to present some embodiments herein, the drawings are not necessarily drawn to scale of the specific embodiments, and some features can be enlarged, removed or partially cut to better show and explain the disclosure of the present application. Some components in the drawings can be adjusted in position according to actual needs without affecting the technical effects. The phrase "in the drawings" or similar language appearing in the specification does not necessarily refer to all the drawings or examples.

[0030] When introducing elements of the present application or preferred embodiments thereof, the terms "first", "the first", "second", "the second" and the like, do not necessarily indicate any order, number or importance in the present disclosure, but are used to distinguish one component from other components.

[0031] As used herein, the term "absorbent article" refers to products which can be placed against or near the body of a wearer (i.e., in abutment with the body) for absorbing and containing various liquid, solid, and semi-solid exudates discharged from the body, which can be collectively referred to as "discharged materials". As described herein, such absorbent articles are intended to be discarded after a limited period of use rather than being laundered or otherwise restored for reuse.

[0032] As used herein, the term "joined" refers to the attachment, bonding, or uniting of two elements to each other. Two elements will be considered joined when they are attached, bonded, or united, directly to each other or indirectly to each other, such as when placed in abutment with each other. Joining can be by means such as adhesives, pressure bonding, heat bonding, ultrasonic welding, stitching, or sewing, among others.

[0033] As used herein, the term "ultrasonic welding" refers to a process performed, for example, by passing a material through a slit between an ultrasonic generator and a backing roll.

[0034] As used herein, the term "elastic material" refers to an elongated substance having elasticity, such as, but not limited to, elastic rubber bands, elastic bands, elastic fiber nonwoven sheeting, and the like. By application of a stretching force, the elastic material can be stretched in at least one direction (e.g., in the longitudinal direction or in the transverse direction), and by removal of the stretching force, it is able to contract / return to approximately its original size.

[0035] As used herein, the term "film" refers to thermoplastic films formed by processes such as cast film or blown film extrusion. The term includes apertured films, slit films, and other perforated films that constitute a transfer film, as well as films that do not transfer liquid, including, but not limited to, barrier films, filled films, breathable films, and oriented films.

[0036] As mentioned previously, it is desirable to provide an absorbent article with better leakage prevention effect, to improve the wearing experience of the wearer. For absorbent articles with a containment gasket, the containment gasket can play a certain sealing role by fitting the wearer's skin. However, when the amount of discharged material is large, for example, exceeds the sealing capacity of the containment gasket, the discharged material that is not timely absorbed by the absorbent core can leak from the containment gasket to the outside of the absorbent article. Such leakage can lead to undesirable contamination of clothing, bedding, human skin, etc., and make the wearer feel frustrated. To solve the above problems, embodiments of the present disclosure provide an absorbent article that is improved at least in terms of leakage prevention.

[0037] Reference Figure 1 For illustrative purposes, one form of an absorbent article 1 of the present disclosure is shown: a pant-type absorbent article, which can be referred to as a waist-worn diaper.

[0038] Figure 1The absorbent article 1 is shown in a flat configuration and in a natural state, not elastically deformed or wrinkled by external forces. The absorbent article 1 has a first direction L and a second direction T, which are perpendicular to each other, wherein the first direction L is a longitudinal direction and the second direction T is a transverse direction. For reference purposes, Figure 1 The longitudinal center axis X and the transverse center axis Y of the absorbent article 1 are also shown in the figure.

[0039] In the first direction L, the absorbent article 1 can be divided into a front region 11, a crotch region (i.e. crotch position) 12, and a back region 13, wherein the crotch region 12 is joined between the front region 11 and the back region 13. In a wear state, the front region 11 covers substantially the part of the wearer's ventral waistline and the back region 13 covers substantially the part of the wearer's dorsal waistline. The front region 11 has front side edges 112 on two laterally opposite sides, and a front end edge 111 extending between the two front side edges 112. The back region 13 has back side edges 132 on two laterally opposite sides, and a back end edge 131 extending between the two back side edges 132. The crotch region 12 has crotch region side edges 121 on two laterally opposite sides, respectively. The front end edge 111 and the back end edge 131 substantially define the two ends of the absorbent article 1 in the first direction L.

[0040] Figure 1 The illustrated single-piece personal care absorbent article 1 needs to be folded in the crotch region 12 and joined the front region 11 and the back region 13 together near the front side edges 112 and the back side edges 132, so as to form a pant configuration. At this time, the front end edge 111 and the back end edge 131 together enclose a waist opening to accommodate the torso of the wearer, and the two crotch region side edges 121 of the crotch region 12 each enclose a leg opening to accommodate the thigh of the wearer.

[0041] For the purpose of facilitating the joining of the front region 11 and the back region 13, side panels 4 can also be provided on the two laterally opposite sides of the back region 13, and each side panel 4 extends beyond the corresponding back side edge 132. A joining structure can be provided between the side panel 4 and the front region 11 to achieve releasably joining. A reliable joining structure is, for example, a hook-and-loop fastener or a magic tape. A portion of the hook-and-loop fastener, for example a large number of micro hooks, can be arranged on the side panel 4, and a portion of the hook-and-loop fastener corresponding to the portion arranged on the side panel 4, for example a large number of micro loops, is arranged on the front region 11. Another releasable joining structure is, for example, a tape coated on at least one of the side panel 4 and the front region 11.

[0042] Figure 1 The releasable joining of the front region 11 and the back region 13 of the absorbent article 1 is only an exemplary embodiment. In some embodiments, as Figure 11As shown, the absorbent article can be a waist-closed absorbent article 1', such as a pant-type product that can also be referred to as a pull-on or a training pant. Such a waist-closed pant-type absorbent article can be readily put on by a wearer by pulling it over the thighs and directly onto the body, providing a convenient operation.

[0043] In the description herein, unless specifically stated otherwise, the following terms are applicable to Figure 1 The element composition of the illustrated waistband-type diaper, such as the configuration, material, function, and the like related to the elasticity, leakage prevention, comfort, and the like for improving the wearer experience, is also applicable to Figure 11 The illustrated waist-closed absorbent article 1' is shown with the chassis 2 and the containment belt 3 (the first containment belt 31 and the second containment belt 32) briefly marked.

[0044] Regardless of whether the absorbent article is waist-open or waist-closed, the waist opening thereof can generally be surrounded by an elastic material, improving the wrapping and comfort of the wearer's waist, and being able to flexibly adapt to different waist circumference populations, achieving a more personalized wearing experience.

[0045] It should be understood that the embodiments of the present disclosure are suitable for providing personal wearing disposable absorbent articles of various styles or specific uses, including but not limited to infant diapers, infant training pants, infant pull-ups, adult incontinence pants, feminine sanitary pants, and the like.

[0046] Referring to Figure 1 and Figure 2 The absorbent article 1 includes a chassis 2, which can be in a one-piece configuration in the L-T plane as the main body of the absorbent article 1. A pair of crotch region side edges 121 are formed by cutting the entire sheet, thereby dividing the front region 11 and the back region 13 on opposite sides of the crotch region 12, and thus configuring the one-piece chassis 2. The side panels 4 can be joined to the chassis 2 at the back region 13. From the vertical direction, i.e., the third direction V, perpendicular to the L-T plane (or from the thickness direction), the chassis 2 can include an inner layer 21 facing the wearer's body when the absorbent article 1 is worn, an outer layer 24 facing away from the wearer's body when the absorbent article 1 is worn, an absorbent core 22 between the outer layer 24 and the inner layer 21, and a liquid-impermeable layer. The liquid-impermeable layer is generally a thin film structure, which can be referred to as a "backsheet", in order to meet the requirements of air permeability and leakage prevention performance of the product.

[0047] The inner layer 21 (or "topsheet") is hydrophilic, which can be a single layer or a multi-layer laminate that can attract water molecules and allow water molecules to pass when in contact with liquid. The outer layer 24 is hydrophobic, which can be a single layer or a multi-layer laminate and does not allow liquid to pass in a direction substantially perpendicular to the single layer or multi-layer laminate. In some embodiments, for example, in Figure 11In the illustrated absorbent article 1', the outer layer 24 can include two layers: an inner bottom layer and an outer bottom layer. Various woven and nonwoven materials can be used to make the inner layer 21 and the outer layer 24. Examples of nonwoven materials can be spunbond, meltblown, coform, carded webs, bonded carded webs, bicomponent spunbond webs, spunlace webs, through-air- bonded webs, and the like, as well as combinations thereof.

[0048] The absorbent core 22 is mainly disposed in the crotch region 12 and can be a composite made of a layered liquid-absorbent raw material. As the liquid-absorbent raw material, for example, a liquid-absorbent fiber such as pulp fiber can be used. In addition, the absorbent core 22 can contain, for example, a superabsorbent polymer as a liquid-absorbent particulate material, or can contain a liquid-absorbent raw material other than the liquid-absorbent fiber and the liquid-absorbent particulate material.

[0049] A pair of containment flaps 3 can be disposed on the body-facing side of the chassis 2, the pair of containment flaps 3 being disposed opposite each other in the transverse direction and extending along the longitudinal direction L to block the leakage of exudates in at least the longitudinal direction and the transverse direction. In some embodiments, the containment flaps 3 can extend along the longitudinal direction L from the front end edge 111 to the back end edge 131. The containment flaps 3 can be joined to the chassis 2 at the ends thereof that are opposite each other in the transverse direction and away from the longitudinal center axis X, while the other ends of the containment flaps 3 that are opposite each other in the transverse direction and closer to the longitudinal center axis X can be movable relative to the chassis 2 to form free ends. The free ends can be specially elasticized, for example, by being provided with elastic material, to impart a body-hugging property to the containment flaps while reducing the irritation to the skin.

[0050] Figure 2 is a cross-sectional view taken generally along the transverse center axis Y of the absorbent article 1, in which the containment flaps 3 are in a laid-flat attitude in an unused state (e.g., a packaged state) of the absorbent article 1.

[0051] Reference Figure 2 The containment flaps 3 include first and second containment flaps 31 and 32, which are spaced apart in the second direction T and extend along the first direction L of the absorbent article 1, respectively, to better wrap the crotch of the wearer and achieve a good fit and seal. Specifically, the first and second containment flaps 31 and 32 can be disposed opposite each other in the second direction T on both sides of the absorbent core 22. More specifically, as shown in Figure 2 the first and second containment flaps 31 and 32 can be symmetrically disposed on both sides of the absorbent core 22 with respect to the longitudinal center axis X. In some embodiments, the first and second containment flaps 31 and 32 can extend along the first direction L from the front end edge 111 to the back end edge 131, respectively.

[0052] The first containment member 31 includes a first containment sheet 311 that includes a first end 3111 and a second end 3112, and a first containment body portion 3113 between the first end 3111 and the second end 3112 of the first containment sheet 311. The first end 3111 of the first containment sheet 311 can be joined to the outer layer 24 at the joint 345 (e.g., adhesive) shown in the figure by any suitable joining means mentioned above to form a fixed end of the first containment member 31. The second end 3112 of the first containment sheet 311 can be free to move relative to other portions of the absorbent article (e.g., the outer layer 24, the inner layer 21, the absorbent core 22) to form a free end of the first containment member 31. The second end 3112 of the first containment sheet 311 can remain in a laid flat position when the absorbent article 1 is not in use by a wearer, and can remain in an upright position to fit the wearer's crotch skin when the absorbent article 1 is in use by a wearer.

[0053] In some embodiments, the first containment member 31 can be joined to the inner layer 21 at the joints 341, 343 (e.g., adhesive) on the side of the first containment member 31 facing the inner layer 21 between the first end 3111 and the second end 3112 of the first containment sheet 311, whereby the first containment sheet 311 is secured to the chassis 2 to prevent the first containment sheet 311 from dislodging from the inner layer 21 or shifting during wearer activities.

[0054] The second containment member 32 includes a second containment sheet 321 that includes a first end 3211 and a second end 3212, and a second containment body portion 3213 between the first end 3211 and the second end 3212 of the second containment sheet 321. The first end 3211 of the second containment sheet 321 can be joined to the outer layer 24 at the joint 355 (e.g., adhesive) shown in the figure by any suitable joining means mentioned above to form a fixed end of the second containment member 32. The second end 3212 of the second containment sheet 321 can be free to move relative to other portions of the absorbent article (e.g., the outer layer 24, the inner layer 21, the absorbent core 22) to form a free end of the second containment member 32. The second end 3212 of the second containment sheet 321 can remain in a laid flat position when the absorbent article 1 is not in use by a wearer, and can remain in an upright position to fit the wearer's crotch skin when the absorbent article 1 is in use by a wearer.

[0055] In some embodiments, similar to the first guard 31, the second guard 32 may be joined to the inner layer 21 at joints 351, 353 (e.g., adhesive) on the side of the second guard sheet 321 facing the inner layer 21 between the first end 3211 and the second end 3212, thereby fixing the second guard sheet 321 to the base plate 2 and preventing the second guard sheet 321 from detaching from the inner layer 21 or from shifting during wearer activity.

[0056] The absorbent article 1 includes an elastic material 33, which comprises a first elastic material disposed in a first enclosure and a second elastic material disposed in a second enclosure. The first elastic material 33 is disposed at the second end 3112 of the first enclosure sheet 311 and is joined to the first enclosure sheet 311 by a joining portion 34 (e.g., an adhesive). The second elastic material 33 is disposed at the second end 3212 of the second enclosure sheet 321 and is joined to the second enclosure sheet 321 by a joining portion 35 (e.g., an adhesive).

[0057] In some embodiments, the elastic material can be sheets, threads, or strands of natural rubber, synthetic rubber, or thermoplastic elastomer polymers. For example, the first elastic material 33 and the second elastic material 33 can be elastic strands, and the number of elastic strands is the same, for example, including 2 to 10 elastic strands, or any other suitable number of elastic strands. The elastic material provides elasticity to the free end of the guardrail 3, thereby enabling it to automatically adjust according to the wearer's body shape and activity level, ensuring that the guardrail 3 fits closely to the wearer's body curves, avoiding gaps, and providing good wrapping and support.

[0058] like Figure 2 As shown, the liquid-impermeable layer 23 of the substrate 2 includes a first liquid-impermeable portion 231, a second liquid-impermeable portion 232, and a third liquid-impermeable portion 233. These portions can be continuous and uninterrupted, allowing the liquid-impermeable layer 23 to present a complete layer or film structure. The first liquid-impermeable portion 231 extends into the first protective body portion 3113, the second liquid-impermeable portion 232 extends into the second protective body portion 3213, and the third liquid-impermeable portion 233 is located between the outer layer 24 and the absorbent core 22. Therefore, the liquid-impermeable layer 23 prevents leakage of the excreted substance encapsulated by the absorbent article 1, at least along the first direction L and the second direction T.

[0059] The extended structure of the impermeable layer 23 effectively forms a continuous leak-proof barrier in the crotch area of ​​the absorbent article, ensuring that even when the mass of the discharged material is large, the discharged material will not permeate outside the absorbent article 1 along the lateral direction T, longitudinal direction L and / or vertical direction V, thereby enhancing the leak-proof performance of the absorbent article 1.

[0060] In some embodiments, a first impermeable portion 231 of the impermeable layer 23 is disposed within the first enclosure body portion 3113 and at least partially joined to the inner side of the first enclosure sheet 311 at a joint 342. The first impermeable portion 231 of the impermeable layer 23 may extend close to a second end 3112 of the first enclosure sheet 311. The first impermeable portion 231 may be spaced apart from the first elastic material 33 so that the first impermeable portion 231 is not affected by the shrinkage of the first elastic material 33. A second impermeable portion 232 of the impermeable layer 23 is disposed within the second enclosure body portion 3213 and at least partially joined to the inner side of the second enclosure sheet 321 at a joint 352. The second impermeable portion 232 of the impermeable layer 23 may extend close to a second end 3212 of the second enclosure sheet 321. The second impermeable portion 232 may be spaced apart from the second elastic material 33 so that the second impermeable portion 232 is not affected by the shrinkage of the second elastic material 33.

[0061] The fixed connection between the impermeable layer 23 and the retaining wall 3 provides a stable bond between the impermeable layer 23 and the retaining wall 3, preventing the impermeable layer 23 from detaching or shifting from the first retaining wall sheet 311 and the second retaining wall sheet 321 during wear due to external forces, such as the wearer's movements and the pressure of the expelled substance. This connection ensures the structural integrity and stability of the absorbent article 1 and improves the wearing comfort of the absorbent article 1.

[0062] like Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the third impermeable portion 233 of the impermeable layer 23 can constitute the main part of the impermeable layer 23, that is, the impermeable portion with the largest area. Along the vertical direction V, the third impermeable portion 233 is located between the absorbent core 22 and the outer layer 24.

Although a plurality of joints 36 provided dispersedly on the surface 2331 of the third impermeable portion 233 facing the outer layer 24 are shown in the figures at intervals, continuous joints may also be formed, for example, along the entire surface 2331 to provide enhanced robust stability between the base film and the outer layer.

[0064] In some embodiments, the first end 3111 of the first containment sheet 311 comprises a first end 3111a and a second end 3111b, wherein the length of the first end 3111a is greater than the length of the second end 3111b, the first end 3111a can be joined to the inner layer 21 at a joint 344 (e.g. adhesive), and the second end 3111b can be joined to the outer layer 24 at a joint 345 (e.g. adhesive), thereby securing the first end 3111 of the first containment sheet 311 to the chassis 2. In some embodiments, the lengths of the first end 3111a and the second end 3111b can be equal, or the length of the first end 3111a can be less than the length of the second end 3111b.

[0065] In some embodiments, the first end 3211 of the second containment sheet 321 comprises a first end 3211a and a second end 3211b, wherein the length of the first end 3211a is greater than the length of the second end 3211b, the first end 3211a can be joined to the inner layer 21 at a joint 354 (e.g. adhesive), and the second end 3211b can be joined to the outer layer 24 at a joint 355 (e.g. adhesive), thereby securing the first end 3211 of the second containment sheet 321 to the chassis 2. In some embodiments, the lengths of the first end 3211a and the second end 3211b can be equal, or the length of the first end 3211a can be less than the length of the second end 3211b.

[0067] Absorbent articles according to embodiments of the present disclosure also relate to an improvement in the skin feel in the crotch region. As previously mentioned, the elastic properties of the elastic material can have a significant impact on the fit and comfort perception of the product. If the elastic properties of the elastic material are weakened, the product can not fit properly and will not form a sufficient seal, which can result in leakage of bodily fluids and a reduced sense of trust and security for the user. If the elastic properties of the elastic material are overemphasized, the elastic material can irritate the user's skin and further leave an imprint on the user's skin, which is particularly disadvantageous for infant users.

[0068] To this end, in some embodiments of the present disclosure, reference is made to Figures 3 to 10A product solution is presented that takes into account both the close fit of the elastic material and the good perception of the user. Overall, the key to this solution lies in the formation of a cavity around the elastic material that fits against the skin, such a cavity can provide a cushioning barrier that relieves the pressure of the elastic material on the skin, thus reducing or even eliminating the traces that the elastic material can create on the skin. This improvement is particularly beneficial for the delicate skin of babies and young children.

[0069] As shown in Figures 3 to 6 , the first containment 31 can comprise a first additional sheet 312 disposed between the first containment sheet 311 and the first elastic material 33, and the second containment 32 can comprise a second additional sheet 322 disposed between the second containment sheet 321 and the second elastic material 33.

[0070] Figure 3 shows the flat laying attitude of the containment 3 in the unused (e.g. packaged) state of the absorbent article 1, Figure 4 shows the standing attitude of the containment 3 in the worn state of the absorbent article 1. Figure 3 and Figure 4 is a cross-sectional view taken substantially along the transversal central axis Y of the absorbent article 1. Figure 5 At Figure 4 , A is enlarged, Figure 6 At Figure 4 , A' is enlarged to show more details of the free end of the containment 3. In the context of this document, "standing" does not mean standing strictly in the vertical direction, but rather, with respect to the flat laying configuration in the packaged state, the containment will stand away from the absorbent core in order to fit the wearer's crotch skin when the absorbent article is worn.

[0071] With reference to Figures 3 to 5 , the first containment 31 comprises a first additional sheet 312, which is folded around the first elastic material 33 and disposed between the first elastic material 33 and the first containment sheet 311, forming a first containment cavity 313 around the first elastic material 33 between the inner side of the first containment sheet 311 and the outer side of the first additional sheet 312.

[0072] The first additional sheet 312 is folded around the first elastic material 33 to form a first end 3121 and a second end 3122, the first end 3121 of the first additional sheet 312 being proximate to the first liquid-impermeable portion 231 of the liquid-impermeable layer 23 and spaced apart from the end of the first liquid-impermeable portion 231, and the second end 3122 of the first additional sheet 312 being proximate to the second end 3112 of the first containment sheet 311. The first end 3121 of the first additional sheet 312 comprises a first end 3121a and a second end 3121b, as shown in Figure 5As shown, the first end 3121a and the second end 3121b have the same length, so that the first end 3121a and the second end 3121b are flush. In some embodiments, the length of the first end 3121a can be slightly greater than the length of the second end 3121b, or the length of the first end 3121a can be slightly less than the length of the second end 3121b. The first additional sheet 312 extends around the first elastic material 33 within the second end 3112 of the first containment sheet 311, and forms a first containment cavity 313 around the first elastic material 33 between the inner side of the first containment sheet 311 and the outer side of the first additional sheet 312. The design of the first containment cavity 313 relieves the pressure of the first elastic material 33 on the skin, reduces the appearance of marks, and improves the softness and comfort of the first containment 31.

[0073] The inner side of the first additional sheet 312 is joined with the first elastic material 33 at the joint 34 (e.g., adhesive), and the first elastic material 33 is fixed. At the first end 3121 of the first additional sheet 312, a first containment joint 314 (e.g., adhesive) is provided on the outer side of the first additional sheet 312, opposite the first end 3121. For example, as shown, the first containment joint 314 can be symmetrically provided on the outer side of the first additional sheet 312. For another example, the first containment joint 314 can also be asymmetrically provided on the outer side of the first additional sheet 312. Figure 5

[0074] The size of the first containment joint 314 can be adjusted according to actual needs, and thereby the size of the cavity 313 is changed. In some embodiments, the size of the first additional sheet 312 can also be adjusted, and thereby the size of the cavity 313 is changed. Whether the size of the joint is adjusted, or the size of the first additional sheet 312 is adjusted, or both sizes are adjusted, as long as it is ensured that the cavity 313 formed by the first containment sheet 311 and the first additional sheet 312 together can cover the elastic material used, especially the elastic material in the area that is joined with the skin of the user in the erected state.

[0075] The arrangement of the first containment joint 314 ensures the firmness of the joint between the first containment sheet 311 and the first additional sheet 312, and helps to form a continuously extending cavity 313 around the first elastic material 33, which makes the free end of the first containment 31 form a structure of a bubble or a bladder. Without affecting the shape fitting performance provided by the first elastic material 33, the cavity 313 can relieve the pressure of the first elastic material 33 on the skin, reduce the appearance of marks, and improve the softness and comfort of the containment. In addition, the structure of the bubble or the bladder also weakens the presence of the elastic structure when viewed, providing a softer psychological suggestion, which helps to improve the trust of the user.

[0076] ​Reference Figure 6 The second containment 32 includes a second additional sheet 322 folded around the second elastic material 33 and disposed between the second elastic material 33 and the second containment sheet 321, forming a second containment cavity 323 around the second elastic material 33 between the inner side of the second containment sheet 321 and the outer side of the second additional sheet 322.

[0077] The configuration and efficacy of the second containment cavity 323 are the same as described above in connection with the first containment 31. Figure 5 The second additional sheet 322 is folded around the second elastic material 33 forming a first end 3221 and a second end 3222, the first end 3221 of the second additional sheet 322 is proximate to the second liquid impermeable portion 232 of the liquid impermeable layer 23 and spaced apart from the distal end of the second liquid impermeable portion 232, and the second end 3222 of the second additional sheet 322 is proximate to the second end 3212 of the second containment sheet 321. The first end 3221 of the second additional sheet 322 includes a first distal end 3221a and a second distal end 3221b, as shown in Figure 6 The first distal end 3221a and the second distal end 3221b are the same length such that the first distal end 3221a and the second distal end 3221b are flush. In some embodiments, the first distal end 3221a can be slightly longer than the second distal end 3221b, or the first distal end 3221a can be slightly shorter than the second distal end 3221b. The second additional sheet 322 extends around the second elastic material 33 within the second end 3212 of the second containment sheet 321, and forms the second containment cavity 323 around the second elastic material 33 between the inner side of the second containment sheet 321 and the outer side of the second additional sheet 322. The design of the second containment cavity 323 reduces the pressure of the second elastic material 33 on the skin, reduces the occurrence of red marks, and improves the softness and comfort of the second containment 32.

[0078] The inner side of the second additional sheet 322 is joined with the second elastic material 33 at the junction 35 (e.g., adhesive), and the second elastic material 33 is secured. At the first end 3221 of the second additional sheet 322, a second containment junction 324 (e.g., adhesive) is provided on the outer side of the second additional sheet 322 opposite the second containment junction 324. For example, as shown in Figure 6 The second containment junction 324 can be symmetrically disposed on the outer side of the second additional sheet 322. For another example, the second containment junction 324 can also be asymmetrically disposed on the outer side of the second additional sheet 322.

[0079] The size of the second protective panel joint 324 can be adjusted according to actual needs, thereby changing the size of the cavity 323. In some embodiments, the size of the second additional sheet 322 can also be adjusted, thereby changing the size of the cavity 323. Whether the size of the joint is adjusted, the size of the second additional sheet 322 is adjusted, or both are adjusted simultaneously, as long as it is ensured that the cavity 323 formed by the second protective panel sheet 321 and the second additional sheet 322 can cover the elastic material used, especially the elastic material in the area that contacts the user's skin in the upright position.

[0080] The arrangement of the second guardrail joint 324 ensures a strong bond between the second guardrail sheet 321 and the second additional sheet 322, and helps form a continuously extending cavity 323 surrounding the second elastic material 33. This continuously extending cavity 323 creates a bubble or air pocket structure at the free end of the second guardrail 32. Without affecting the conformal fit provided by the second elastic material 33, the cavity 323 reduces pressure on the skin, minimizes marks, and enhances the softness and comfort of the guardrail. Furthermore, the bubble or air pocket structure visually minimizes the presence of the elastic structure, providing a softer psychological cues and helping to increase user confidence.

[0081] like Figures 7 to 10 As shown, some other embodiments for forming cavities are provided, different from... Figures 3 to 6 The additional layer shown is located on the inside.

[0082] See Figures 7 to 10 The first protective enclosure 31 may include a first additional sheet 312 disposed outside the first protective enclosure sheet 311, and the second protective enclosure 32 may include a second additional sheet 322 disposed outside the second protective enclosure sheet 321. Figure 7 The diagram shows the flat position of the protective enclosure 3 in the unused (e.g., packaged) state of the absorbent article 1. Figure 8 The protective barrier 3 is shown in its upright position when the absorbent product 1 is worn. Figure 7 and Figure 8 It is a cross-sectional view taken roughly along the transverse central axis Y of the absorbent product 1. Figure 9 right Figure 8 The area at point B has been magnified. Figure 10 right Figure 8 The area at B' has been enlarged to show more details of the free end of the guard 3. In this context, "standing upright" does not mean strictly standing upright in a vertical direction, but rather refers to the guard standing upright away from the absorbent core to fit the wearer's crotch skin when the absorbent product is worn, relative to its flat configuration in the packaged state.

[0083] refer toFigures 7 to 9 The first containment 31 includes a first additional sheet 312 folded around the first elastic material 33 and disposed outside the first containment sheet 311, forming a first containment cavity 313 around the first elastic material 33 between the outside of the first containment sheet 311 and the inside of the first additional sheet 312.

[0084] The first additional sheet 312 is folded around the first elastic material 33 to form a first end 3121 and a second end 3122. The first end 3121 of the first additional sheet 312 extends slightly beyond the first elastic material 33, and the second end 3122 of the first additional sheet 312 is adjacent to the second end 3112 of the first containment sheet 311. The first end 3121 of the first additional sheet 312 includes a first end tip 3121a and a second end tip 3121b. As shown in FIG. 3A, the first end tip 3121a and the second end tip 3121b have the same length, such that the first end tip 3121a and the second end tip 3121b are flush. In some embodiments, the length of the first end tip 3121a can be slightly greater than the length of the second end tip 3121b, or the length of the first end tip 3121a can be slightly less than the length of the second end tip 3121b. The first additional sheet 312 extends around the first elastic material 33 and the first containment sheet 311 at the second end 3112 of the first containment sheet 311, and forms the first containment cavity 313 around the first elastic material 33 between the inside of the first additional sheet 312 and the outside of the first containment sheet 311. The design of the first containment cavity 313 reduces the pressure of the first elastic material 33 on the skin, reduces the occurrence of indentations, and improves the softness and comfort of the first containment 31. Figure 9 A first containment joint 314 (e.g., adhesive) is disposed on the inside of the first end 3121 of the first additional sheet 312 opposite the first end tip 3121a. The first containment joint 314 extends proximate to the first end 3121 of the first additional sheet 312. The first additional sheet 312 is joined to the first containment sheet 311 by the first containment joint 314 at the first end 3121 of the first additional sheet 312. For example, as shown in FIG. 3A, the first containment joint 314 can be symmetrically disposed on the inside of the first additional sheet 312. For another example, the first containment joint 314 can also be asymmetrically disposed on the inside of the first additional sheet 312.

[0085] Figure 9

[0086] ​​The arrangement of the first guardrail joint 314 ensures a strong bond between the first guardrail sheet 311 and the first additional sheet 312, and helps form a continuously extending cavity 313 surrounding the first elastic material. This continuously extending cavity 313 creates a bubble or air pocket structure at the free end of the first guardrail 31. Without affecting the conformal fit provided by the first elastic material 33, the cavity 313 reduces pressure on the skin, minimizes marks, and enhances the softness and comfort of the guardrail. Furthermore, the bubble or air pocket structure visually minimizes the presence of the elastic structure, providing a softer psychological cues and helping to increase user confidence.

[0087] For details, please refer to the following: Figure 10 The second enclosure 32 includes a second additional sheet 322, which is folded around the second elastic material 33 and disposed on the outside of the second enclosure sheet 321. A second enclosure cavity 323 of the second elastic material 33 is formed between the outside of the second enclosure sheet 321 and the inside of the second additional sheet 322.

[0088] and combination Figure 9 The cavity of the first retaining wall 31 is described in the same manner as the cavity described above. A second additional sheet 322 is folded around the second elastic material 33 to form a first end 3221 and a second end 3222. The first end 3221 of the second additional sheet 322 extends slightly beyond the second elastic material 33, and the second end 3222 of the second additional sheet 322 is adjacent to the second end 3212 of the second retaining wall sheet 321. The first end 3221 of the second additional sheet 322 includes a first end 3221a and a second end 3221b, as shown below. Figure 10 As shown, the first end 3221a and the second end 3221b are of the same length, so that the first end 3221a and the second end 3221b are flush. In some embodiments, the length of the first end 3221a may be slightly greater than the length of the second end 3221b, or the length of the first end 3221a may be slightly less than the length of the second end 3221b. The second additional sheet 322 extends around the second elastic material 33 and the second protective sheet 321 at the second end 3212 of the second protective sheet 321, and a second protective cavity 323 is formed between the inner side of the second additional sheet 322 and the outer side of the second protective sheet 321, surrounding the second elastic material 33. The design of the second protective cavity 323 reduces the pressure of the second elastic material 33 on the skin, reduces the occurrence of chafing marks, and improves the softness and comfort of the second protective sheet 32.

[0089] A second containment joint 324 (e.g., adhesive) is disposed on the inner side of the first end 3221 of the second additional sheet 322. The second containment joint 324 extends proximate to the first end 3221 of the second additional sheet 322. The second additional sheet 322 is joined to the second containment sheet 321 by the second containment joint 324 at the first end 3221 of the second additional sheet 322. For example, as shown in Figure 10 the second containment joint 324 can be symmetrically disposed on the inner side of the second additional sheet 322. For another example, the second containment joint 324 can also be asymmetrically disposed on the inner side of the second additional sheet 322.

[0090] The second containment joint 324 is configured to ensure the firmness of the joint between the second containment sheet 321 and the second additional sheet 322, and to help form a continuously extending cavity 323 around the second elastic material 33 between the second containment joints 324, which forms a bubble or bladder structure at the free end of the second containment 32. The cavity 323 can reduce the pressure of the second elastic material 33 on the skin and reduce the occurrence of marks, and improve the softness and comfort of the containment, without affecting the fit performance provided by the second elastic material 33. In addition, the bubble or bladder structure also weakens the presence of the elastic structure when viewed, providing a softer psychological suggestion and helping to improve user trust.

[0091] Similarly, in the embodiment shown in Figures 7 to 10 the size of the first containment joint 314 and the second containment joint 324 can be adjusted according to actual needs, and thereby the size of the cavities 313 and 323 can be changed. In some embodiments, the size of the first additional sheet 312 and the second additional sheet 322 can also be adjusted, and thereby the size of the cavities 313 and 323 can be changed. Whether the size of the joint is adjusted, or the size of the additional sheet is adjusted, or both the size of the joint and the size of the additional sheet are adjusted, as long as it is ensured that the cavity 313 formed by the first containment sheet 311 and the first additional sheet 312 together and the cavity 323 formed by the second containment sheet 321 and the second additional sheet 322 together can cover the elastic material used, especially the elastic material in the area that is engaged with the skin of the user in the upright state.

[0092] With any of the above embodiments, any suitable material can be used to make the first and second containment sheet 311, 321. For example, each of the first and second containment sheet 311, 321 is made of at least one of the following materials: nonwoven material, film material, composite of nonwoven material and film material. Similarly, any suitable material can be used to make the first and second additional sheet 312, 322, for example, each of the first and second additional sheet 312, 322 is made of at least one of the following materials: nonwoven material, film material, composite of nonwoven material and film material, elastic material, nonwoven material compounded with elastic material, film material compounded with elastic material.

[0093] In some embodiments, the fiber fineness of the nonwoven material can range from 0.6D to 3D, which roughly corresponds to a fiber diameter range of 5 microns to 30 microns.

[0094] With any of the above embodiments, each of the first and second containment sheet 311, 321 can have a plain weave, 3D embossing or holes, and can also be printed with a design. Similarly, each of the first and second additional sheet 312, 322 can have a plain weave, 3D embossing or holes, and can also be printed with a design. Such processing changes the visual effect of the absorbent article, meets the individual needs of the wearer for the appearance or feel of the absorbent article 1, and improves the wearer's experience.
