Description

[Technical Field]

[0001] The present invention relates to a pants-type absorbent article. [Background technology]

[0002] Pants-type absorbent articles are known that can be used as tape-type (unfolded) absorbent articles by cutting off a portion of the waistband member of the pants-type absorbent article. For example, Patent Document 1 discloses a diaper that can be used either as a pants-type diaper in which opposing sides of the diaper are joined together, or as an open-type diaper in which the opposing sides are joined together with fastening pieces. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 05-317356 Summary of the Invention [Problem to be solved by the invention]

[0004] The diaper described in Patent Document 1 is a disposable diaper that has a tear line provided on the front body near the joint where the front and rear body panels are joined at opposing sides, for separating the front body panel from the rear body panel. After the front and rear body panels are separated along the tear line, they can be fastened together via a fastening piece extending from the opposing side of the back body panel. However, the diaper described in Patent Document 1 is not designed for wearers to put on themselves; rather, it is designed to be worn by a wearer. Therefore, if a wearer using such a diaper attempts to separate the waistband member constituting the front body panel along the tear line while sitting or standing (squatting) on ​​the toilet, it may be difficult to apply force to the tear line, or the waistband member may stretch, making it difficult to cut. This may require the wearer to repeatedly grab the diaper and try to tear it. Furthermore, excessive force may be applied during the separation, resulting in damage to parts of the diaper. Thus, there is room for improvement in the ease with which a wearer can self-don pants-type absorbent articles that can also be used as tape-type diapers.

[0005] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a pants-type absorbent article that can also be used as a tape-type article and is easy for the wearer to put on. [Means for solving the problem]

[0009] At least the following matters will become clear from the description of this specification and the accompanying drawings. A pants-type absorbent article for adults having an absorbent main body with intersecting vertical, horizontal, and front-to-back directions, a front waistline section and a rear waistline section arranged overlapping the absorbent main body in the front-to-back direction, a waistline member that stretches in the left-to-right direction, and an engaging member that removably engages with the non-skin side of the front waistline section, with the front waistline section and the rear waistline section joined together, wherein the engaging member is joined to the front waistline section, and the front waistline section has a high elasticity section in at least a part of the overlapping region that overlaps with the engaging member in a planar view, the high elasticity section having a higher elastic modulus than the surrounding area, between both left-to-right side edges of the front waistline section.

[0010] With such pants-type absorbent articles, before wearing, if you hold the engaging member with one hand and spread it outward in the left-right direction, and then hold the part of the front waistband portion corresponding to the overlapping area where the engaging member overlapped before spreading it out with the other hand, and apply a pulling force outward in the left-right direction to separate them, the front waistband portion will be prone to tearing at the high elasticity portion because the high elasticity portion is difficult to stretch.

[0011] In such a pants-type absorbent article, it is desirable that the front waist portion has the high-elasticity portion in an upper region including the upper edge in the vertical direction, or in a lower region including the lower edge, in at least a part of the region that overlaps with the engaging member in the left-right direction.

[0012] In such a pants-type absorbent article, the upper edge or lower edge of the front waistband is the region that becomes the tearing initiation point when the wearer attempts to tear the front waistband. Since the high-elasticity portion is a portion that is difficult to stretch and easily tears, by having such a high-elasticity portion in the upper region including the upper edge or the lower region including the lower edge, the tearing initiation point becomes easily torn, allowing the wearer to smoothly perform the tearing action.

[0013] In such a pants-type absorbent article, it is desirable that in the natural state, the minimum value of the vertical length of the front waistband portion in the area where the front waistband portion and the engaging member overlap in the left-right direction is 80 mm or more and 150 mm or less.

[0014] In such a pants-type absorbent article, by setting the vertical length of the front waistband to 150 mm or less, the wearer can easily tear the front waistband. If the vertical length of the front waistband is too short, the area covering the wearer's body may become too small, which may cause anxiety, but by setting the vertical length to 80 mm or more, such anxiety can be reduced.

[0015] In such a pants-type absorbent article, it is preferable that the high-elasticity portion of the front waistband portion is provided with a perforation line having a length in the up-down direction.

[0016] In such pants-type absorbent articles, the highly elastic portion is a portion that is difficult to stretch and easily torn, so by providing a cut line in such a highly elastic portion, the front waist portion becomes easier to tear.

[0017] In such a pants-type absorbent article, both left and right side portions of the front waistband portion and the rear waistband portion are joined by a pair of joints, and in a natural state, it is desirable that the length of the joints in the up-down direction be longer than the length of the cut line.

[0018] In such pants-type absorbent articles, because the length of the tear line is shorter, when a certain force is applied to tear the article, the force per unit length acting on the tear line is greater than the force per unit length acting on the joint, making it easier to tear the tear line.

[0019] In such a pants-type absorbent article, it is desirable that the engaging member has an engaging portion that engages with the non-skin side of the front waistband portion, and that before the ventral abutment portion of the front waistband portion is separated from the rear waistband portion along the cut line, the engaging portion is located inside the cut line in the left-right direction.

[0020] In such pants-type absorbent articles, if the cut line is located laterally inward of the engagement portion, the area for attaching the engagement member is reduced after tearing, and even if the article is used without tearing, it is prone to tearing at the cut line when pulled up during wear. By locating the engagement portion laterally inward of the cut line, a wider range of waist sizes can be accommodated, and tearing when pulled up during use without tearing can be suppressed.

[0021] In such a pants-type absorbent article, before the ventral contact portion of the front waistband portion is separated from the rear waistband portion along the cut line, it is desirable that the engaging member be positioned so as to cover at least a portion of the cut line, and that the upper end of the cut line be located above the upper end of the engaging member, or the lower end of the cut line be located below the lower end of the engaging member.

[0022] With such pants-type absorbent articles, the tear line can be seen before opening the engaging member, making it easier for the user to determine at what position the front waistband portion should be torn, thereby improving operability.

[0023] In such a pants-type absorbent article, it is desirable that, in a natural state, the high-elasticity portion has a length of 10 mm or more extending inward in the left-right direction from the cut line.

[0024] In such a pants-type absorbent article, after tearing along the tear line, the portion of the high-elasticity section located inside the tear line becomes the portion to be gripped when engaging the engaging member with the front waistband section. If the gripping portion is a highly elastic section that is resistant to deformation, it is less likely to curl, making it easier for the wearer to grip. Furthermore, if the gripping portion is at least as wide as the thumb, it becomes even easier to grip.

[0025] In such a pants-type absorbent article, it is desirable that the length from the inner end of the engaging portion to the inner end of the engaging member in the left-right direction be 5 mm or more and 50 mm or less.

[0026] In such a pants-type absorbent article, by making the length from the inner edge of the engaging portion to the inner edge of the engaging member 5 mm or more, it becomes easier to peel the tab 30 from the front waistline portion by pinching a position inside the inner edge of the engaging portion with your fingertips. On the other hand, by making the length 50 mm or less, the distance from the position where the engaging member is pinched to the tear line does not become too long, and it is possible to prevent a decrease in operability when tearing the front waistline portion along the tear line.

[0027] It is desirable that such a pants-type absorbent article has a pair of the engaging members, each of which is joined to the front waistline portion on both sides in the left-right direction, and that the front waistline portion has the high elasticity portion in at least a portion of each of the overlapping areas on both sides in the left-right direction that overlap with the pair of engaging members when viewed in a plane, and that low elasticity portions having an elastic modulus smaller than that of the high elasticity portions are provided continuously between the high elasticity portions on both sides in the left-right direction of the front waistline portion.

[0028] According to such a pants-type absorbent article, by providing a low elasticity portion that is easy to stretch between the high elasticity portions on the left and right that are difficult to stretch, it is possible to improve the fit of the waist portion of the absorbent article.

[0029] In such a pants-type absorbent article, it is desirable that the engaging member has an engaging portion that engages with the non-skin side of the front waistband portion, and that when the engaging portion is engaged with the front waistband portion and when viewed in a plane, the low-elasticity portion has a portion that overlaps with at least a part of the engaging portion.

[0030] In such pants-type absorbent articles, the engagement portion is more likely to engage with the low elasticity portion, which is more easily deformed (stretchable) than the high elasticity portion, which is less likely to deform. Therefore, when engaging, the low elasticity portion has a portion that overlaps with at least a part of the engagement portion, making it easier for the wearer to engage with the engagement portion.

[0031] In such a pants-type absorbent article, it is desirable that the maximum length of the engaging member in the left-right direction is 20 mm or more and 120 mm or less.

[0032] With such pants-type absorbent article, by having a maximum length within the above-mentioned range, it is easy to hold the engaging member in your hand to open it, tear the front waistband portion, and then engage with the front waistband portion without having to change your hand.

[0033] In such a pants-type absorbent article, it is desirable that the front waist portion has a cut line at one end in the left-right direction that has a length in the up-down direction, and that after the ventral abutment portion of the front waist portion is separated from the rear waist portion along the cut line, when the engaging member is engaged with the non-skin side of the front waist portion, the engaging member has a protrusion that protrudes downward in the up-down direction beyond the lower edge of the front waist portion.

[0034] In such a pants-type absorbent article, the lower edge of the front waistband is hidden by the protruding part of the engaging member at the portion overlapping the engaging member, making it difficult to see the end (lower edge) of the front waistband after tearing, thereby achieving an appearance that is more similar to that of underwear.

[0035] === Implementation form === Hereinafter, a pants-type (shorts-type) napkin 1 (hereinafter simply referred to as "napkin 1") will be described as an example of a pants-type absorbent article according to the present invention. Note that pants-type absorbent articles also include pants-type diapers and the like.

[0036] <Basic structure of napkin 1> Fig. 1 is a schematic perspective view of a napkin 1. Fig. 2 is a plan view of the napkin 1 in an unfolded and stretched state, as viewed from the skin side in the thickness direction. Fig. 3 is a schematic cross-sectional view taken along line AA in Fig. 2.

[0037] As shown in FIG. 1, the napkin 1 has a "vertical direction," a "left-right direction," and a "front-to-back direction" that intersect (are perpendicular to) one another. Also, as shown in FIG. 3, it has a "thickness direction," which is the direction in which each component is layered. In the vertical direction, the side that faces the wearer's waist when the napkin 1 is worn by a wearer is referred to as the "upper side," and the side that faces the wearer's crotch is referred to as the "lower side." In the front-to-back direction, the side that faces the wearer's stomach when worn is referred to as the "front side," and the side that faces the wearer's back is referred to as the "rear side." In the thickness direction, the side that comes into contact with the wearer's skin when the napkin 1 is worn by a wearer is referred to as the "skin side," and the opposite side is referred to as the "non-skin side."

[0038] The napkin 1 of this embodiment comprises a liquid-absorbent main body 10 that absorbs excretory fluids such as menstrual blood, a waistline member 20 that is arranged on the non-skin side of the absorbent main body 10 and has a front waistline portion 20f and a rear waistline portion 20b, and a pair of tabs 30 (corresponding to engaging members) provided on both the left and right sides of the waistline member 20.

[0039] The unfolded state of the napkin 1 shown in Fig. 2 is a state in which the pair of side seams 40 provided on both lateral sides of the napkin 1 are separated, and the napkin 1 is opened and unfolded flat. In other words, the napkin 1 is folded in half at the center position CL in the up-down direction from the unfolded state shown in Fig. 2, and both lateral sides of the front waistline portion 20f and the rear waistline portion 20b are joined at a pair of side seams 40 (seams) to form a pants-type napkin. Examples of joining methods for the side seams 40 include well-known joining methods such as thermal welding and ultrasonic welding. In the pants-type napkin 1 (Fig. 1), the front waistline portion 20f and the rear waistline portion 20b are connected in a ring shape, and one waistline opening 1a and a pair of leg openings 1b are formed.

[0040] The "stretched state" of the napkin 1 refers to a state in which the entire napkin 1 (the entire product) is stretched without wrinkles by stretching each elastic member of the napkin 1 (e.g., the absorbent body elastic member 50 described below and the skin-side sheets 22 and 23, etc.). Specifically, it refers to a state in which each component constituting the napkin 1 (e.g., the non-skin-side sheet 21 and skin-side sheets 22 and 23 described below) is stretched until its dimensions match or are close to those of the component alone (i.e., the dimensions when the elastic properties of the elastic members are not expressed). In this embodiment, when comparing the absorbent main body 10, it is preferable to measure and compare the absorbent main body 10 in a disengaged (separated) state and in a pants-like state (before tearing along the perforation line 25). The tab 30 may be measured either after opening the napkin 1 or in a disengaged state. The above-mentioned measurement method is merely an example, and other measurement methods may also be used.

[0041] (Absorbent body 10) As shown in Fig. 2, the absorbent main body 10 has a generally rectangular shape in plan view, with its longitudinal direction aligned with the vertical direction of the napkin 1. As shown in Fig. 3, the absorbent main body 10 has an absorbent core 11 aligned along the longitudinal direction (vertical direction), a top sheet 12 arranged closer to the skin than the absorbent core 11, and a back sheet 13 arranged closer to the skin than the absorbent core 11. However, the absorbent main body 10 may also include sheet members other than these. For example, a second sheet (not shown) may be provided between the top sheet 12 and the absorbent core 11 in the thickness direction.

[0042] The absorbent core 11 is a member that absorbs and retains liquids such as menstrual blood, and is formed from liquid-absorbent fibers such as pulp fibers mixed with superabsorbent polymer (SAP). The outer periphery of the absorbent core 11 may be covered with a liquid-permeable sheet member (core wrap sheet) such as tissue paper or nonwoven fabric.

[0043] The top sheet 12 is a liquid-permeable sheet member that can come into contact with the wearer's skin when worn, and is made of, for example, a hydrophilic air-through nonwoven fabric or a spunbond nonwoven fabric.

[0044] The backsheet 13 has a two-layer structure including a liquid-impermeable sheet 13a for preventing leakage of liquids such as menstrual blood absorbed in the absorbent core 11 to the outside, and a hydrophobic sheet 13b arranged on the non-skin side of the liquid-impermeable sheet 13a. The liquid-impermeable sheet 13a may be made of, for example, a resin film, and the hydrophobic sheet 13b may be made of, for example, a flexible nonwoven fabric. However, the hydrophobic sheet 13b is not necessarily provided, and the backsheet 13 may be made of only the liquid-impermeable sheet 13a.

[0045] Furthermore, leakage preventing walls (not shown) may be provided on both the left and right sides of the absorbent main body 10. The leakage preventing walls are portions that correspond to so-called three-dimensional gathers, and when the napkin 1 is worn, the leakage preventing walls stand up from both the left and right sides of the absorbent main body 10 toward the wearer's skin, thereby preventing excrement such as menstrual blood from leaking out of the absorbent main body 10.

[0046] The absorbent body 10 is provided with a plurality of absorber elastic members 50 that stretch along its longitudinal direction. The absorber elastic members 50 are made of, for example, rubber thread, and in this embodiment, are arranged between the liquid-impermeable sheet 13a and the hydrophobic sheet 13b in a state stretched in the longitudinal direction (FIG. 3). In the napkin 1 of this embodiment, five absorber elastic members 50 are provided at predetermined intervals in the left-right direction (see FIG. 2). The stretch ratio of the absorber elastic members 50 is preferably approximately 1.4 to 3.3. The stretch ratio is expressed as the value obtained by dividing the length of the elastic member in a stretched state by the length of the elastic member in its natural state. It is recommended to set the stretch ratio of the absorber elastic members 50 to a relatively high ratio. By doing so, the absorber body 10 is lifted toward the wearer's skin, as shown in FIG. 8 described below, and the absorber body 10 is more likely to fit closely to the wearer's crotch area (vaginal opening), thereby suppressing leakage of excrement.

[0047] (Waist member 20) The waistline member 20 is an exterior body composed of multiple sheet members, and includes at least a non-skin side sheet 21 and skin side sheets 22 and 23 (see FIG. 3). In the following description, the portion of the waistline member 20 that is in front of (towards the ventral side of) the central position CL in the longitudinal direction will be referred to as the front waistline portion 20f, and the portion that is behind (towards the back side of) the central position CL will be referred to as the rear waistline portion 20b. The front waistline portion 20f is the portion that touches the ventral side of the wearer's body when the napkin 1 is worn. The rear waistline portion 20b is the portion that touches the back side of the wearer's body when the napkin 1 is worn.

[0048] The non-skin side sheet 21 is a non-stretchable sheet member arranged on the closest non-skin side of the napkin 1, and is made of, for example, a spunbond nonwoven fabric or an SMS nonwoven fabric. As shown in Fig. 2, the non-skin side sheet 21 of this embodiment has a shape that is narrowed inward in the left-right direction at the longitudinal center.

[0049] The skin side sheet 22 is a stretchable sheet member laminated on the skin side of the non-skin side sheet 21 on the front side (ventral side) in the longitudinal direction. The skin side sheet 22 is formed, for example, from a stretchable nonwoven fabric. The "stretchable nonwoven fabric" refers to a nonwoven fabric that contains stretchable fibers with stretchability and extensible fibers with lower shrinkage than the stretchable fibers, and that has been subjected to an appropriate stretching process such as gear stretching. The skin side sheet 22 of this embodiment can use, as the stretchable fibers, fibers of polyurethane-based elastomer, which is a type of elastic thermoplastic elastomer, and can use, as the extensible fibers, fibers of polypropylene (PP), a polyolefin-based resin, which is a type of inelastic thermoplastic resin.

[0050] The skin side sheet 22 is joined to the non-skin side sheet 21 by a plurality of sheet joining portions (not shown) scattered therethrough, thereby imparting stretchability to the front waistband portion 20f at least in the left-right direction. In this embodiment, the sheet joining portions are formed using a known joining method such as ultrasonic welding.

[0051] The skin side sheet 23 is a stretchable sheet member laminated on the skin side of the non-skin side sheet 21 at the rear side (back side) in the longitudinal direction. The skin side sheet 23 has the same configuration as the skin side sheet 22. That is, the skin side sheet 23 is formed from a stretchable nonwoven fabric and is joined to the non-skin side sheet 21 by a plurality of scattered sheet joining portions (not shown). This provides stretchability at least in the left-right direction to the rear waistband portion 20b.

[0052] The waistband member 20 may include sheet members other than the non-skin-side sheet 21 and the skin-side sheets 22, 23. For example, the waistband member 20 may have a three-layer structure in which a non-stretch nonwoven fabric is placed on the skin side of the stretchable skin-side sheets 22, 23, and the stretchable nonwoven fabric is sandwiched between the non-stretch nonwoven fabrics. In the three-layer structure, the skin-side sheets 22, 23 may be stretch films. The non-skin-side sheets 21 may be separated into front and rear. In this case, the non-skin-side surface of the backsheet 13 may be exposed between the front and rear non-skin-side sheets 21, or a separate non-skin-side sheet may be provided in the crotch area to connect the front and rear non-skin-side sheets 21.

[0053] (Tab 30) The napkin 1 has a pair of tabs 30 (engaging members) on both lateral sides of the waistline member 20 that detachably engage with the non-skin side of the front waistline portion 20f. Note that FIG. 2 shows the tabs 30 engaged with the non-skin side of the front waistline portion 20f in a virtual view of the napkin 1 as seen from the skin side. The tabs 30 have a base sheet 31 and engaging portions 32. The base sheet 31 is a sheet member made of nonwoven fabric or the like. The outer lateral ends of the base sheet 31 are joined to the waistline member 20 by side joining portions 40. In other words, the front waistline portion 20f, the rear waistline portion 20b, and the tabs 30 are joined together by the side joining portions 40. However, the tabs 30 may be joined to the waistline member 20 at a location other than the side joining portions 40.

[0054] The engaging portion 32 is provided at the end of the base sheet 31 opposite the side joined by the side joining portion 40 in the left-right direction. The engaging portion 32 is provided on the skin side of the base sheet 31, faces the non-skin side of the front waistline portion 20f, and is a member that releasably engages with the non-skin side of the front waistline portion 20f. An example of the engaging portion 32 is a male member of a hook-and-loop fastener that has a protrusion (hook member) that catches on the fibers that make up the non-skin side sheet 21. Note that a member (for example, a female member of a hook-and-loop fastener) that easily engages with the engaging portion 32 may be provided on the non-skin side of the non-skin side sheet 21.

[0055] <How to put on Sanitary Napkin 1> Figures 4A and 4B are schematic cross-sectional views of the napkin 1 as seen from the waist-opening 1a side. Figure 4A is a diagram of the napkin 1 used in pants form, and Figure 4B is a diagram of the napkin 1 used in tape form. Figure 5 is an expanded plan view of the napkin 1 in a state where the front waistline portion 20f has been separated from the rear waistline portion 20b along the cutting line 25.

[0056] When the napkin 1 is initially taken out of the package, it is in a pants-like shape (FIG. 4A) with the front waistband 20f and the rear waistband 20b connected in a circular shape, allowing the wearer to put on and take off the napkin 1 while it remains in the pants-like shape.

[0057] The front waistline portion 20f of the napkin 1 has tear lines 25 extending in the vertical direction at both left-right end portions. Therefore, the front waistline portion 20f can be torn in the vertical direction along the tear lines 25, and a portion of the front waistline portion 20f can be separated from the rear waistline portion 20b. After separation, the napkin 1 has a tape shape with a pair of tabs 30 extending outward in the horizontal direction from the rear waistline portion 20b, as shown in Fig. 5. Therefore, the wearer can put on and take off the napkin 1 in the tape shape.

[0058] In the following description, the portion of the front waistline portion 20f that is separated from the rear waistline portion 20b on at least one side in the left-right direction is also referred to as the "ventral contact portion 20fA." Additionally, the portion of the front waistline portion 20f that is not separated from the rear waistline portion 20b and remains on the side joining portion 40 side is also referred to as the "non-separated portion 20fB."

[0059] 6A to 6C and 7A to 7D are diagrams illustrating an example of a method for a wearer to put on or take off the napkin 1. The wearer of the napkin 1 generally puts on or takes off the napkin 1 by himself or herself. The wearer puts on or takes off the napkin 1 while sitting on a toilet bowl or the like (not shown) as shown in FIG. 6C etc., or while standing (in a half-squat position).

[0060] Next, an example of a method for wearing the napkin 1 in a tape-type manner will be described. First, as shown in FIG. 6A, the wearer opens the tab 30 on one side of the pants-type napkin 1 in the left-right direction outward (to one side) to expose the perforation line 25. Next, as shown in FIG. 6B, the wearer tears the end of one side of the front waistline portion 20f in the vertical direction along the perforation line 25 to separate the abdominal contact portion 20fA, which is part of the front waistline portion 20f, from the rear waistline portion 20b. Next, as shown in FIG. 6C, the wearer pulls the separated portion of the waistline member 20 to the front of the thigh and wraps the waistline member 20 around one thigh. Then, as shown in FIG. 7A, the wearer engages the tab 30 (engagement portion 32) with the non-skin side of the front waistline portion 20f (abdominal contact portion 20fA) above the thigh.

[0061] In the state shown in Fig. 7A, the side joint portions 40 are positioned on the thighs, and the absorbent main body 10 (absorbent core 11) hangs down between the thighs. Therefore, the wearer rotates the napkin 1 around the thighs (the direction shown on the right thigh in Fig. 7A). Then, as shown in Fig. 7B, the wearer aligns the side joint portions 40 with their sides and pulls the absorbent main body 10 up between their thighs.

[0062] Next, as shown in Fig. 7C, the wearer opens the opposite tab 30 outward in the left-right direction and tears the other left-right end of the front waistline portion 20f vertically along the tear line 25, separating the abdominal-side contact portion 20fA, which is part of the front waistline portion 20f, from the rear waistline portion 20b. At the same time, the wearer aligns the absorbent main body 10 between the thighs (the center in the width direction of the wearer) while correcting the inclination of the absorbent main body 10, which is tilted toward the thighs around which the napkin 1 is wrapped, so that it aligns with the direction of extension of the thighs. Then, as shown in Fig. 7D, the wearer pulls the separated portion of the waistline member 20 to the front of the thighs, wraps the waistline member 20 around the opposite thigh, and engages the tab 30 with the non-skin-side surface of the front waistline portion 20f above the thigh.

[0063] 4B, the abdominal contact portion 20fA of the front waistline portion 20f, which was separated along the cutting line 25, is reconnected to the rear waistline portion 20b in a circular shape by the pair of tabs 30. In addition, the wearer's thighs pass through the pair of leg openings 1b of the napkin 1. Finally, the wearer pulls up the napkin 1, completing the putting on of the napkin 1.

[0064] Thus, by providing the tab 30 that releasably engages with the non-skin side of the front waistline portion 20f, when the wearer uses the napkin 1 in a tape-type configuration, the wearer can engage the tab 30 with the front waistline portion 20f while visually checking the tab 30 on the front side of the wearer. This improves ease of putting on the napkin 1 by the wearer. Furthermore, when removing the napkin 1, the wearer can remove the tab 30 from the front waistline portion 20f while visually checking the tab 30 on the front side of the wearer.

[0065] When the napkin 1 is worn in the pants-like state, it is possible to remove the napkin 1 while it is still in the pants-like state, but it is also possible to remove the napkin 1 by tearing the front waistband portion 20f along the tear line 25. Conversely, when the napkin 1 is worn in the tape-like state, it is also possible to remove the napkin 1 without removing the tab 30.

[0066] In order to make a pants-type (shorts-type) napkin like the napkin 1 of this embodiment so that it can be worn by the wearer as a tape-type napkin, if the wearer tears a part of the waistband member and places it on the body, and then fixes the tab to the waistband, if the waistband member is difficult to tear, there is a risk that the wearer will have to repeatedly grab the napkin and try to tear it, or that they may apply more force than necessary and damage part of the napkin.

[0067] In this regard, the napkin 1 of this embodiment has the following configuration. Figs. 8 and 9 are front views of the pants-type napkin 1. First, as shown in Figs. 2 and 5, the front waistline portion 20f and the rear waistline portion 20b each have skin-side sheets 22, 23 that stretch in the left-right direction and waistline elastic members 24, and are stretchable in the left-right direction. That is, at least the left-right central portions of the front waistline portion 20f and the rear waistline portion 20b stretch in the left-right direction due to stretchable regions (low-elasticity portions 20EA, described later) that stretch in the left-right direction, allowing the napkin 1 to fit the waist of the wearer. Furthermore, as shown in Fig. 8 (and Figs. 2 and 5), the front waistline portion 20f has high-elasticity portions 20NA at both left-right ends, which have a higher elastic modulus than the surrounding areas. 9, the high elasticity portions 20NA in this embodiment are provided on both left-right sides of the front waistline portion 20f from the side edges 20fe to positions overlapping with at least parts of the engaging portions 32, and in the up-down direction from the upper edge 20fup to the lower edge 20fdw of the front waistline portion 20f. Note that the high elasticity portions 20NA are not limited to the above-mentioned ranges, and may be provided in at least parts of the overlapping regions 20fc (see FIG. 8) where the front waistline portion 20f and the tab 30 overlap in a plan view, between both left-right side edges 20fe, 20fe of the front waistline portion 20f.

[0068] The elastic modulus of the front waistband portion 20f may be determined, for example, by preparing samples by cutting out the high elasticity portion 20NA and the portion between the left and right high elasticity portions 20NA from the front waistband portion 20f in its natural state, conducting a tensile test using a tensile testing machine (for example, an autograph tensile testing machine AG-1KN1 manufactured by Shimadzu Corporation), and calculating the tensile modulus.

[0069] In this embodiment, the high elasticity portion 20NA of the front waistline portion 20f is formed by ultrasonically joining the skin side sheet 22 and the non-skin side sheet 21 that constitute the front waistline portion 20f, by making the joining pattern of the scattered sheet joining portions (not shown) different between the high elasticity portion 20NA and the low elasticity portion 20EA (described later). Specifically, for example, the high elasticity portion 20NA may be formed by increasing the number of sheet joining portions in the high elasticity portion 20NA to weaken the stretchability of the skin side sheet 22.

[0070] Note that ultrasonic bonding is not the only method, and other bonding methods such as heat sealing may also be used. The high elasticity portion 20NA may also be formed by other methods. For example, a separate, inelastic sheet member such as a nonwoven fabric may be attached to the portion where the high elasticity portion 20NA is to be formed, thereby making the skin side sheet 22 in the high elasticity portion 20NA portion less stretchable, thereby forming the high elasticity portion 20NA with a high elastic modulus. Alternatively, for example, instead of using an elastic nonwoven fabric as the material for the front waistband portion 20f, the front waistband portion 20f may be formed from two inelastic sheet members such as nonwoven fabric, and an elastic member made of rubber thread that stretches in the left-right direction may be disposed between the two sheet members. The thickness of the rubber thread may be varied between the high elasticity portion 20NA and the low elasticity portion 20EA, thereby forming the high elasticity portion 20NA with a desired elastic modulus.

[0071] When using the napkin 1 as a tape-type napkin, the wearer first holds the tab 30, which is spread outward in the left-right direction, with one hand as shown in FIG. 6B , and holds the front waistline portion 20f at a portion corresponding to the overlapping region 20fc that overlaps with the tab 30 shown in FIG. 8 with the other hand, and applies a pulling force outward in the left-right direction to separate the two. Because the high-elasticity portion 20NA of the front waistline portion 20f is resistant to deformation (stretching), the front waistline portion 20f is easily torn at the high-elasticity portion 20NA. Being able to easily tear the front waistline portion 20f at the first stage of the wearer's donning procedure improves wearability and allows for smooth progression to the next step. Similarly, when tearing the opposite tab 30 (during the action shown in FIG. 7C ), the wearer can easily tear the front waistline portion 20f at the high-elasticity portion 20NA, improving wearability even when sitting.

[0072] In addition, although the high elasticity portion 20NA of the front waistline portion 20f in this embodiment is provided from the upper edge 20fup to the lower edge 20fdw in the vertical direction, the high elasticity portion 20NA may be provided in at least a portion of the region overlapping the tab 30 in the horizontal direction, in an upper region including the upper edge 20fup, or in a lower region including the lower edge 20fdw. The upper edge 20fup or the lower edge 20fdw of the front waistline portion 20f is the region that serves as the starting point for tearing when tearing the front waistline portion 20f as shown in FIGS. 6B and 7C. In particular, when removing the product and tearing one end of the front waistline portion 20f in the vertical direction along the tear line 25, as shown in FIG. 6B, users often tear from the upper edge 20fup side of the front waistline portion 20f. In such cases, if the high-elasticity portion 20NA is provided in the upper region including the upper edge 20fup, the tearing action can be performed more smoothly. On the other hand, as shown in Fig. 7C, when the user is sitting and tearing the opposite end (the other side) in the left-right direction along the tear line 25 in the up-down direction, the user often tears from the lower edge 20fdw side of the front waistline portion 20f. In such cases, if the high-elasticity portion 20NA is provided in the lower region including the lower edge 20fdw, the tearing action can be performed more smoothly.

[0073] The napkin 1 is a pants-type absorbent article for adults, and is configured such that the vertical length L1 (FIG. 8) of the front waistline portion 20f is shorter than that of, for example, pants-type disposable diapers intended for care recipients who are fitted with pants-type absorbent articles by a caregiver. Specifically, as shown in FIG. 8, in the napkin 1 in its natural state where the tabs 30 joined to the side joining portions 40 are engaged with the non-skin side of the front waistline portion 20f while being closed inward in the left-right direction, the minimum value of the vertical length L1 of the front waistline portion 20f in the region 20fc where the front waistline portion 20f and the tabs 30 overlap in the left-right direction is 80 mm or more and 150 mm or less.

[0074] If the initial state of the napkin 1 after removal from the package is the state shown in Fig. 8, measurements are taken with the napkin 1 in its initial and natural state. If the initial state is not the state shown in Fig. 8 (for example, when the tab 30 is folded), measurements are taken with the napkin 1 in its natural state (the waistline member 20 in its natural state) with the tab 30 spread out from the side joint portion 40 inward in the left-right direction and engaged with the front waistline portion 20f.

[0075] The region 20fc of the front waistline portion 20f that overlaps with the tab 30 is a portion that is easily grasped by the wearer when opening the tab 30 and tearing the front waistline portion 20f, as shown in Figures 6B and 7C. Therefore, by setting the vertical length L1 of the region 20fc to 150 mm or less, the wearer can easily tear the front waistline portion 20f. On the other hand, if the length L1 of the front waistline portion 20f is made too short, the area covering the wearer's body may become too small, which may cause the wearer to feel uneasy. However, by setting the vertical length L1 of the region 20fc to 80 mm or more, such uneasiness can be alleviated.

[0076] 9, a perforation line 25 having a length in the vertical direction is provided in the high elasticity portion 20NA of the front waistline portion 20f. The perforation line 25 is a line that guides the wearer when tearing the front waistline portion 20f, and providing such a perforation line 25 in the high elasticity portion 20NA, which is less stretchy and more easily torn, makes it easier to tear the front waistline portion 20f.

[0077] 9, in the napkin 1 in its natural state, where the tabs 30 joined to the side joints 40 are closed inward in the left-right direction and engaged with the non-skin side of the front waistline portion 20f, the length L2 of the side joints 40 in the up-down direction is longer than the length L3 of the perforation line 25. Because the length of the perforation line 25 is shorter, when a certain force is applied to perform the tearing action as shown in FIGS. 6B and 7C, the force per unit length applied to the perforation line 25 is greater than the force per unit length applied to the side joints 40. Therefore, when tearing the front waistline portion 20f, it is easier to tear along the perforation line 25.

[0078] 9, before the ventral-side contact portion 20fA of the front waistline portion 20f is separated from the rear waistline portion 20b along the cut line 25 and the tab 30 is engaged with the non-skin-side surface of the front waistline portion 20f, the engagement portion 32 is located inside the cut line 25 in the left-right direction. If the cut line 25 is located inside the engagement portion 32 in the left-right direction, for example, when the diaper is wrapped around the thigh as shown in FIG. 7D after the tearing action shown in FIG. 7C is performed, the left-right length of the ventral-side contact portion 20fA of the front waistline portion 20f is shortened, and the area for attaching the tab 30 is reduced. In other words, after separation, the tab 30 is pulled inward in the left-right direction so as to straddle the cut line 25 on the ventral-side contact portion 20fA side and fixed, narrowing the range of waistline sizes that can be used. Furthermore, even when the napkin 1 is used without tearing, the front waistline portion 20f stretches left and right in the portion inside the engaging portion 32 in the left-right direction, and if the perforation line 25 is provided in such a position, the product (napkin 1) will be prone to tearing at the perforation line 25 when pulled up during wear. Therefore, by positioning the engaging portion 32 inside the perforation line 25 in the left-right direction as in this embodiment, a wide range of waistline sizes can be accommodated, while also preventing tearing when pulled up when used without tearing.

[0079] Similarly, before the ventral-side contact portion 20fA of the front waistline portion 20f is separated from the rear waistline portion 20b along the cut line 25 and when the tab 30 is engaged with the non-skin-side surface of the front waistline portion 20f, the tab 30 is positioned to cover at least a portion of the cut line 25. The upper end 25up of the cut line 25 is located above the upper end 30up of the tab 30. When the tab 30 is positioned to cover the entire cut line 25 of the front waistline portion 20f, the wearer cannot determine the location of the cut line 25 until the tab 30 is opened outward in the left-right direction. However, by being able to see a portion of the cut line 25 before opening the tab 30, the wearer can more easily determine where to tear the front waistline portion 20f, thereby improving wearability. In this embodiment, the lower end of the cut line 25 is covered by the tab 30 and is difficult to see, but the lower end of the cut line 25 may be located below the lower end of the tab 30. This also makes it easier for the wearer to determine where to tear.

[0080] Furthermore, the high elasticity portion 20NA extends from the side edge 20fe of the front waistline portion 20f inward in the left-right direction relative to the cut line 25. In its natural state, the high elasticity portion 20NA preferably has a length of 10 mm or more (length W20 in FIG. 9 ) extending inward in the left-right direction from the cut line 25. After the front waistline portion 20f is torn along the cut line 25, the portion of the high elasticity portion 20NA located inward relative to the cut line 25 serves as a grip when the wearer engages the tab 30 with the non-skin-facing side of the front waistline portion 20f (the abdominal contact portion 20fA). Because the high elasticity portion 20NA is resistant to deformation, the gripping portion is less likely to curl, making it easier for the wearer to grip. Furthermore, by having the length W20 be 10 mm or more, the length becomes close to or greater than the width of the wearer's thumb, making it easier to grip.

[0081] When a wearer peels (releases) the tab 30 from the front waistline portion 20f, it is expected that the wearer will hold the tip of the tab 30 and peel it off. As shown in FIG. 9 , the length W30 from the inner end 32e of the engagement portion 32 to the inner end 30e of the tab 30 in the left-right direction is preferably 5 mm or more and 50 mm or less. By making the length W30 from the inner end 32e of the engagement portion 32 to the inner end 30e of the tab 30 5 mm or more, the wearer can easily peel the tab 30 from the front waistline portion 20f by pinching a portion of the tab 30 inward from the inner end 32e of the engagement portion 32 with their fingertips. On the other hand, by making the length W30 50 mm or less, the distance from the pinched position of the tab 30 to the tear line 25 does not become too long, which prevents a decrease in operability when tearing the front waistline portion 20f along the tear line 25.

[0082] 2, in the pants-type absorbent article 1 in an unfolded and stretched state, the maximum length W5 of the tab 30 in the left-right direction is preferably 20 mm or more and 120 mm or less. By making the left-right length W5 of the tab 30 20 mm or more, the wearer can easily hold the tab 30 when engaging the tab 30 with the front waistline portion 20f. On the other hand, by making the left-right length W6 of the tab 30 120 mm or less, the tab 30, which opens outward, can be prevented from contacting the toilet bowl when the napkin 1 is wrapped around the thighs. Furthermore, by not making the left-right length W5 of the tab 30 too long, the wearer does not need to re-grasp the tab 30 to a position closer to the engaging portion 32 so that the engaging portion 32 can be easily engaged with the front waistline portion 20f after opening the tab 30 and tearing the front waistline portion 20f.

[0083] Furthermore, the base sheet 31 constituting the tab 30 of this embodiment is a nonwoven fabric or the like, and the tab 30 itself does not substantially have any stretchable elements. Comparing the tab 30 to the front waistline portion 20f, the tab 30 has an even greater elastic modulus than the high elasticity portion 20NA of the front waistline portion 20f. In other words, the tab 30 is less likely to deform (stretch) than the high elasticity portion 20NA. Therefore, when holding the tab 30 and the front waistline portion 20f and tearing along the tear line 25 as shown in FIGS. 6B and 7C , the force pulling the tab 30 is easily transmitted to the high elasticity portion 20NA of the front waistline portion 20f.

[0084] 2, in the unfolded and stretched napkin 1, the length L6 from one end of the napkin 1 to the center CL in the up-down direction (the direction perpendicular to the left-right direction and along the longitudinal direction of the absorbent body 10) is preferably 200 mm or more and 350 mm or less. By making the length L6 200 mm or more, the napkin 1 can be adjusted to fit the size of an adult wearer. On the other hand, by making the length L6 350 mm or less, the napkin 1 is less likely to droop when wrapped around the thighs, and the napkin 1 can be prevented from coming into contact with the toilet bowl.

[0085] In the napkin 1 of this embodiment, as shown in Fig. 8, the front waistline portion 20f has high elasticity portions 20NA, 20NA in at least a portion of each of the overlapping regions 20fc on both left and right sides that overlap the pair of tabs 30 in a plan view. A low elasticity portion 20EA, which has an elastic modulus lower than that of the high elasticity portion 20NA, is provided continuously between the high elasticity portions 20NA, 20NA on both left and right sides of the front waistline portion 20f. As shown in Fig. 5, the low elasticity portion 20EA is a portion that stretches in the left and right direction due to the skin side sheet 22 and waistline elastic members 24. The presence of the low elasticity portions 20EA allows the napkin 1 to fit the waist of the wearer. In particular, when the napkin 1 is used as a tape-type napkin (FIG. 4B), the abdominal contact portion 20fA of the front waistline portion 20f is separated from the rear waistline portion 20b, but the abdominal contact portion 20fA is pulled outward in both the left and right directions between the pair of tabs 30, making it easier to fit around the wearer's waist. Furthermore, after the tabs 30 are attached, the high elasticity portions 20NA, 20NA are provided laterally outward of the engagement portions 32. Furthermore, the high elasticity portions 20NA, 20NA are located closer to the skin than the tabs 30. Because the high elasticity portions 20NA are less likely to deform, the left and right ends of the front waistline portion 20f are less likely to curl. Since the high elasticity portions 20NA are in contact with the skin when worn, this can also reduce discomfort to the wearer.

[0086] Furthermore, when the engagement portion 32 of the tab 30 is engaged with the front waistline portion 20f, the low elasticity portion 20EA preferably has a portion that overlaps with at least a part of the engagement portion 32 in a plan view. The engagement portion 32 is more likely to engage with a portion of the low elasticity portion 20EA that is more easily deformed (easily stretched and contracted) than with the high elasticity portion 20NA that is less likely to deform. In other words, the protrusions of the engagement portion 32 that are provided to hook onto the fibers are more likely to hook onto a portion that has wrinkled due to contraction than onto a portion that is close to being taut. Therefore, when engaging the engagement portion 32, having a portion that overlaps with the low elasticity portion EA makes it easier for the wearer to engage the engagement portion 32.

[0087] Fig. 10 is a front view of the napkin 1 with the tab 30 engaged after separation along the perforation line 25. The napkin 1 shown in Fig. 10 shows a state in which the abdominal-side contact portion 20fA of the front waistline portion 20f has been separated from the rear waistline portion 20b along the perforation line 25, and the separated abdominal-side contact portion 20fA has been naturally spread to engage the tab 30 with the non-skin-side surface of the front waistline portion 20f. As shown in the figure, with the tab 30 engaged, the tab 30 has a protrusion 30T that protrudes downward in the vertical direction beyond the lower edge 20fdw of the front waistline portion 20f. Even when the front waistline portion 20f is torn along the cut line 25 to be used as a tape-type napkin and the tab 30 is re-engaged, the protruding portion 30T of the tab 30 hides both left and right ends of the lower edge 20fdw of the front waistline portion 20f, making it difficult to see the end (lower edge 20fdw) of the torn front waistline portion 20f. This allows the napkin 1 to have an appearance more similar to that of underwear.

[0088] ===Other=== The above-described embodiments are intended to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and it goes without saying that the present invention includes equivalents thereof.

[0089] In the above-described embodiment, elastic sheets such as elastic nonwoven fabrics are used as the skin-side sheets 22, 23 constituting the waistline member 20, thereby imparting lateral elasticity to the waistline member 20. However, other elastic members may be provided in the waistline member 20. For example, as shown in Fig. 2, waistline elastic members 24 such as rubber threads may be provided at the upper ends of the front waistline portion 20f and the rear waistline portion 20b so as to be stretchable in the lateral direction. The provision of such waistline elastic members 24 further improves the fit at the waistline opening 1a, and can prevent the waistline member 20 from shifting position when the napkin 1 is worn.

[0090] In the above-described embodiment, the tabs 30 are provided on both the left and right sides of the waistline member 20, but they may be provided on only one side. For example, when in use, the tab 30 provided on only one side may be pulled to easily tear along the inner left and right edges of the side joint portions 40, which have a large difference in rigidity in the front waistline portion 20f. This results in a pants-type napkin that can be unfolded on only one side when in use. In this case, since the inner left and right edges of the side joint portions 40 function as the tear lines 25 of this embodiment, perforations or the like are not necessarily provided.
