[0005] In the absorbent articles described in Patent Documents 1 and 2, a non-removable first absorbent body (absorbent body and first absorbent core) and a removable second absorbent body (absorbent assembly and second absorbent core layer) are stacked on top of each other. Users of such absorbent articles generally remove the second absorbent body, which has absorbed bodily fluids, and dispose of it by rolling it up with the top sheet facing inward, or by folding it (hereinafter simply referred to as "rolling up, etc.") and placing it in a trash can or similar. Patent Documents 1 and 2 do not disclose individual packaging and / or packaging for containing absorbent articles.
[0006] However, simply rolling up the second absorbent body makes it difficult to maintain that state, and even if it is disposed of in a trash can, it may open up, exposing the top sheet. Furthermore, even if that state can be maintained, there is a risk that odors related to bodily fluids may leak from the outer surface or sides. In such cases, if the trash can is in a public restroom or other place used by others, psychological resistance may arise, such as embarrassment at the possibility of others seeing the discarded second absorbent body, or guilt at disposing of the second absorbent body in a dirty or smelly state.
[0007] Therefore, the object of the present invention is to provide an individual package and / or packaging for a pant-type absorbent article that makes it easy to maintain a rolled-up state when disposing of the removed second absorbent body, and makes it difficult for the resulting odor to diffuse. [Means for solving the problem]

MODE FOR CARRYING OUT THE INVENTION
[0012] Specifically, the present disclosure relates to the following aspects. [Aspect 1] An individual package of a panty-type absorbent article, comprising: the absorbent article having a longitudinal direction, a width direction, and a thickness direction orthogonal to each other, and comprising an absorbent main body including an absorber; and an individual packaging bag for accommodating the absorbent article, wherein the absorbent article has, in a deployed state and in the longitudinal direction, a front body surrounding region having a front edge, a rear body surrounding region having a rear edge, and a crotch region disposed between the front body surrounding region and the rear body surrounding region, the absorbent main body includes a first absorbent main body disposed in the crotch region and inseparably joined to the absorbent article, and a second absorbent main body disposed on the skin side of the first absorbent main body and removably joined to the absorbent article, the second absorbent main body includes an airtight film member disposed on the non-skin side, and the individual packaging bag includes a display portion displaying a design in which the first absorbent main body and the second absorbent main body are laminated, and a pair of lateral joining portions for sealing the individual packaging bag.
[0013] In this individual package, a design in which the first absorbent main body and the second absorbent main body are laminated, that is, a design in which the absorbent main body is double-layered, is displayed on the display portion of the individual packaging bag. Therefore, the user can understand that, in the absorbent article in the individual packaging bag, the second absorbent main body on the skin side is removable and can be discarded alone.
[0014] Furthermore, when the second absorbent body on the skin side is removed for disposal and rolled up or folded (hereinafter simply referred to as "rolling up, etc.") with the skin-side sheet material facing inward, the outer surface becomes a non-breathable film material positioned on the non-skin side. Therefore, when the second absorbent body is rolled up, etc., leakage of odors related to bodily fluids from its outer surface can be suppressed.
[0015] In addition, when using the absorbent material, for example, one of the pair of lateral joints can be torn open to open the individual packaging bag and remove the absorbent material. When disposing of the second absorbent body, the second absorbent body, which is rolled up or otherwise in a rolled-up state, can be inserted through the opening of the individual packaging bag and stored in the bag. This makes it easier to maintain the second absorbent body in a rolled-up state.
[0016] Therefore, when disposing of the removed second absorbent body, it is easier to maintain its rolled-up state, making it less likely for odors to spread. Consequently, the risk of the top sheet being exposed and odor leakage is suppressed, reducing the embarrassment and guilt associated with disposing of the second absorbent body in public restrooms, etc. Furthermore, the absorbent material can be used easily for extended periods, and the second absorbent body can be disposed of hygienically when removed.
[0017] [Aspect 2] The individual packaging body according to embodiment 1, wherein the individual packaging bag is formed of a non-breathable film material.
[0018] In this individual packaging, the individual packaging bag is made of a non-breathable film material. Therefore, when disposing of the removed second absorbent body, placing the second absorbent body inside the individual packaging bag can further suppress the leakage of odors to the outside and make them less likely to spread to the outside. Consequently, the embarrassment and guilt associated with disposing of the second absorbent body in a public restroom or similar place can be further reduced.
[0019] [Aspect 3] The individual packaging according to embodiment 1 or 2, wherein the first absorbent body includes a breathable film member positioned on the non-skin side.
[0020] In the absorbent article contained in this individual packaging, the first absorbent body, which is positioned on the non-skin side, includes a breathable film material on the non-skin side. Therefore, when the absorbent article is worn, moisture-laden air inside the absorbent article can be released to the outside. This suppresses stuffiness inside the absorbent article. Furthermore, when disposing of the absorbent article, including the first absorbent body, it can be disposed of hygienically by being wrapped in a large material that includes the rear and front waist areas.
[0021] [Aspect 4] The individual packaging according to any one of embodiments 1 to 3, wherein the second absorbent body is disposed on the non-skin side surface and includes a surface bonding portion that can be bonded to the skin side surface.
[0022] In this individual packaging, when the second absorbent core is rolled up with the skin side facing inward for disposal, the surface joint of the non-skin side that is rolled up can be joined to the skin side, thereby fixing the rolled-up state. This makes it easier to maintain the second absorbent core in a rolled-up state. Furthermore, it becomes possible to make it more difficult for the generated odor to diffuse.
[0023] [Aspect 5] The individual packaging body according to any one of embodiments 1 to 4, wherein the individual packaging bag further includes a vertical joint extending from one of the pair of horizontal joints to the other.
[0024] In this individual packaging, the individual packaging bag has a pair of horizontal and vertical joints. After opening one of the joints and removing the absorbent material, the shape of the individual packaging bag is maintained by the other two joints. As a result, when disposing of the second absorbent body, it can be easily placed back into the individual packaging bag in a rolled-up state.
[0025] When all three joints are opened, the individual packaging bag becomes roughly sheet-like. When the second absorbent body is rolled up together with the individual packaging bag, the vertical joints re-adhere, maintaining that state. This allows the second absorbent body to be disposed of in a more compact form.
[0026] [Aspect 6] The absorbent article, in its deployed state, comprises a plurality of front-waist elastic members in the front waist region that extend in the width direction and are arranged at a predetermined front pitch in the longitudinal direction. The absorbent article comprises, in the width direction, alternating body-to-body joining portions in which the second absorbent body is removably joined to the first absorbent body, and body-to-body non-joint portions in which the second absorbent body is not joined to the first absorbent body, wherein the body-to-body non-joint portions are located at least in the central part in the width direction and on the front side in the longitudinal direction of the second absorbent body, as described in any one or two of embodiments 1 to 5.
[0027] In this individual packaging, the second absorbent body has a joint between the bodies. Therefore, when the second absorbent body is rolled up for disposal, the joint between the bodies re-adheres, making it easier to maintain the rolled-up state. In addition, in this individual packaging, the joints between the bodies and the non-jointed parts between the bodies are provided alternately. As a result, the first absorbent body contracts in the width direction along with the elastic member around the front of the body, making it easier for the second absorbent body to lift up. Consequently, the user can easily pick up the lifted second absorbent body with their fingers. This allows the user to easily fine-tune the position of the second absorbent body when wearing it, improving the fit. Furthermore, the user can easily remove the second absorbent body when disposing of it.
[0028] [Aspect 7] In its deployed state, the absorbent article comprises a plurality of rear-body elastic members in the rear-body region that extend in the width direction and are arranged at a predetermined rear pitch in the longitudinal direction. The absorbent article comprises, in the width direction, alternating body-to-body joining portions in which the second absorbent body is detachably joined to the first absorbent body, and body-to-body non-joint portions in which the second absorbent body is not joined to the first absorbent body, wherein the body-to-body non-joint portions are located at least in the central part in the width direction and on the rear side in the longitudinal direction of the second absorbent body, as described in any one of embodiments 1 to 6.
[0029] In this individual packaging, the second absorbent body has a joint between the bodies. Therefore, when the second absorbent body is rolled up for disposal, the joint between the bodies re-adheres, making it easier to maintain the rolled-up state. In addition, in this individual packaging, the joints between bodies and the non-jointed parts between bodies are provided alternately. As a result, the first absorbent body contracts in the width direction along with the elastic member around the rear body, making it easier for the second absorbent body to lift up. Consequently, the user can easily pick up the lifted second absorbent body with their fingers. This allows the user to easily fine-tune the position of the second absorbent body when wearing it, improving the fit. Furthermore, the user can easily remove the second absorbent body when disposing of it.
[0030] [Aspect 8] The individual packaging according to any one of embodiments 1 to 7, wherein the first absorbent body has a first absorbent body front edge which is the edge of the first absorbent body closer to the front edge, the second absorbent body has a second absorbent body front edge which is the edge of the second absorbent body closer to the front edge, and in the unfolded state, the first absorbent body front edge is positioned closer to the front edge than the second absorbent body front edge, and the absorbent article further comprises a front cover sheet which covers the first absorbent body front edge but does not cover the second absorbent body front edge.
[0031] In this individual packaging, the absorbent article is further provided with a predetermined front cover sheet. Therefore, while wearing the absorbent article, the front cover sheet covering the front edge of the first absorbent body makes it less likely for leakage to occur at the front edge of the first absorbent body. Furthermore, when removing the second absorbent body, the front cover sheet does not cover the front edge of the second absorbent body, making it easier to remove and dispose of by rolling it up or other means.
[0032] [Aspect 9] The individual packaging according to any one of embodiments 1 to 8, wherein the first absorbent body has a first absorbent body rear edge which is the edge of the first absorbent body closer to the rear edge, the second absorbent body has a second absorbent body rear edge which is the edge of the second absorbent body closer to the rear edge, and in the unfolded state, the first absorbent body rear edge is positioned closer to the rear edge than the second absorbent body rear edge, and the absorbent article further comprises a rear cover sheet that covers the rear edge of the first absorbent body but does not cover the rear edge of the second absorbent body.
[0033] In this individual packaging, the absorbent article is further provided with a predetermined rear cover sheet. Therefore, while wearing the absorbent article, the rear cover sheet covering the rear edge of the first absorbent body makes it less likely for leakage to occur at the rear edge of the first absorbent body. Furthermore, when removing the second absorbent body, the rear cover sheet does not cover the rear edge of the second absorbent body, making it easier to remove and dispose of by rolling it up or other means.
[0034] [Aspect 10] A packaging comprising a plurality of individual packages of pant-type absorbent articles, the packaging comprising a package containing the plurality of individual packages, each of the plurality of individual packages having a longitudinal direction, a width direction and a thickness direction perpendicular to each other, the absorbent article comprising an absorbent body including an absorbent material, and an individual packaging bag containing the absorbent article, the absorbent article having, in an unfolded state and in the longitudinal direction, a front waist region having a front edge, a rear waist region having a rear edge, and a crotch region positioned between the front waist region and the rear waist region The absorbent body comprises a first absorbent body positioned in the groin area and irremovably bonded to the absorbent article, and a second absorbent body positioned on the skin side of the first absorbent body and removably bonded to the absorbent article, wherein the second absorbent body comprises a non-breathable film member positioned on the non-skin side, the individual packaging bag comprises a pair of transverse joints sealing the individual packaging bag, and the package comprises a product display section showing a design in which the first absorbent body and the second absorbent body are laminated.
[0035] This packaging displays a design in the product labeling area of the package that shows the first absorbent body and the second absorbent body stacked on top of each other, that is, a design where the absorbent body is made up of two layers. Therefore, users can understand that the second absorbent body, which is on the skin side, is removable and can be disposed of separately from the absorbent item inside the package.
[0036] Then, when the second absorbent body on the skin side is removed for disposal and rolled up with the skin-side sheet material facing inward, the outer surface becomes a non-breathable film material positioned on the non-skin side. Therefore, when the second absorbent body is rolled up, leakage of odors related to bodily fluids from its outer surface can be suppressed.
[0037] In addition, when using the absorbent article, for example, one of the pair of lateral joints can be torn open to open the individual packaging bag and remove the absorbent article. When disposing of the second absorbent body, the second absorbent body, which is rolled up or otherwise in a state, can be inserted through the opening of the individual packaging bag and stored in the individual packaging bag. This makes it easier to maintain the second absorbent body in a rolled-up or similar state and suppresses the leakage of any odors generated to the outside.
[0038] Therefore, when disposing of the removed second absorbent body, it is easier to maintain its rolled-up state, making it less likely for odors to spread. Consequently, the risk of the top sheet being exposed and odor leakage is suppressed, reducing the embarrassment and guilt associated with disposing of the second absorbent body in public restrooms, etc. Furthermore, the absorbent material can be used easily for extended periods, and the second absorbent body can be disposed of hygienically when removed.
[0039] (First Embodiment) The following describes the individual packaging of the pant-type absorbent article according to the embodiment. In this embodiment, a pant-type sanitary napkin is used as an example of the pant-type absorbent article. However, the present invention is not limited to this example and can be applied to other types of pant-type absorbent articles without departing from the spirit of the invention. Examples of other types of pant-type absorbent articles include adult disposable diapers and children's disposable diapers.
[0040] First, an example of the configuration of the panty-type absorbent article contained in the individual packaging according to the embodiment will be described. Figures 1 to 8 are diagrams illustrating an example of the configuration of the panty-type absorbent article according to the embodiment, specifically, a panty-type sanitary napkin 1. Specifically, Figure 1 is a perspective view of the panty-type sanitary napkin 1. Figure 2 is a view of the skin side of the panty-type sanitary napkin 1 in its unfolded state. Figures 3 and 4 are views of the skin side and non-skin side of the absorbent body 3 in its unfolded state, respectively. Figure 5 is a view of the skin side of the first absorbent body 5 in its unfolded state. Figures 6 and 7 are views of the skin side and non-skin side of the second absorbent body 7 in its unfolded state, respectively. Figure 8 is a partial end view of the VIII-VIII end face of Figure 2.
[0041] However, the "unfolded state" of a panty-type absorbent article (shorts-type napkin 1) means the state in which the pair of locking parts that form the boundary between the front and rear waist regions of the panty-type absorbent article are released, and the panty-type absorbent article is spread out on a flat surface until the non-stretchable material (e.g., nonwoven fabric) constituting the panty-type absorbent article is no longer wrinkled without tearing. If the panty-type absorbent article is equipped with an elastic member, the elastic member is stretched until the non-stretchable material is no longer wrinkled. The front waist region, rear waist region, pair of locking parts, elastic member, non-stretchable material (e.g., nonwoven fabric), etc. will be described later.
[0042] The panty-type sanitary napkin 1 comprises a waist opening 101 and a pair of leg openings 103 (one leg opening 103a and the other leg opening 103b). The panty-type sanitary napkin 1 further comprises a pair of locking parts 105 (one locking part 105a and the other locking part 105b) extending from the waist opening 101 toward the pair of leg openings 103. The pair of locking parts 105 lock the front waist area 11 and the rear waist area 15, which will be described later.
[0043] The panty-type sanitary napkin 1 comprises an absorbent body 3 that absorbs menstrual blood and an outer casing 9 that has the shape of panties. When unfolded, the absorbent body 3 has a rectangular shape with a longitudinal direction L and a width direction W. The absorbent body 3 is fixed to the outer casing 9 by a body-to-outer casing joint 107 made of hot melt adhesive.
[0044] The panty-type sanitary napkin 1, in its unfolded state, has a longitudinal direction L and a width direction W that are perpendicular to each other, originating from the absorbent body 3, and a thickness direction T that is perpendicular to the longitudinal direction L and the width direction W. Note that the longitudinal direction L and the width direction W refer to the long and short directions of the absorbent body 3, respectively, and do not refer to the long and short directions of the panty-type sanitary napkin 1 in its unfolded state.
[0045] The shorts-type sanitary napkin 1, in its unfolded state and along its longitudinal direction L, comprises a front waist area 11 having a front edge 17, a rear waist area 15 having a rear edge 19, and a crotch area 13 positioned between the front waist area 11 and the rear waist area 15. The front waist area 11 and the rear waist area 15 are areas equipped with a pair of locking parts 105. The crotch area 13 is the area between the front waist area 11 and the rear waist area 15, forming a leg opening 103. The front edge 17 and the rear edge 19 refer to the edges on the front waist area 11 side and the rear waist area 15 side, respectively, that demarcate the waist opening 101.
[0046] The panty-type sanitary napkin 1, in its unfolded state, has a width-direction centerline WC extending parallel to the width-direction W at the center of the longitudinal direction L. The panty-type sanitary napkin 1, in its unfolded state, also has a longitudinal centerline LC extending parallel to the longitudinal direction at the center of the width-direction W. The crotch area 13 is divided by the width-direction centerline WC into a front crotch area 13a near the front edge 17 and a rear crotch area 13b near the rear edge 19.
[0047] The outer casing 9 comprises a first outer casing sheet 111 that extends from the front waist area 11 to the rear waist area 15 and is positioned on the non-skin side, and a second outer casing sheet 113 that extends from the front waist area 11 to the rear waist area 15 and is positioned on the skin side. Each of the first outer casing sheet 111 and the second outer casing sheet 113 is made of a hydrophobic nonwoven fabric. The first outer casing sheet 111 is folded toward the skin side at its front edge 17 and rear edge 19.
[0048] In the deployed state, the front waist region 11 includes a plurality of front opening elastic members 123 positioned closer to the front edge 17 and a plurality of front waist elastic members 115 positioned closer to the crotch region 13, between the first outer sheet 111 and the second outer sheet 113. The plurality of front opening elastic members 123 extend from one locking portion 105a to the other locking portion 105b and are spaced apart at a predetermined pitch in the longitudinal direction L. The plurality of front waist elastic members 115 extend from one locking portion 105a to the other locking portion 105b and are spaced apart at a predetermined front pitch (for example, 5 mm) in the longitudinal direction L. Each of the multiple front opening elastic members 123 and the multiple front body elastic members 115 is joined to the first exterior sheet 111 and the second exterior sheet 113 by an internal joint 117 made of hot melt adhesive, while stretched relative to the first exterior sheet 111 and the second exterior sheet 113.
[0049] In the deployed state, the rear torso region 15 includes a plurality of rear opening elastic members 125 positioned near the rear edge 19 and a plurality of rear torso elastic members 119 positioned near the crotch region 13, between the first outer sheet 111 and the second outer sheet 113. The plurality of rear opening elastic members 125 extend from one locking portion 105a to the other locking portion 105b and are spaced apart at a predetermined pitch in the longitudinal direction L. The plurality of rear torso elastic members 119 extend from one locking portion 105a to the other locking portion 105b and are spaced apart at a predetermined rear pitch (for example, 5 mm) in the longitudinal direction L. Furthermore, in the deployed state, the rear crotch region 13b is provided with a plurality of rear leg elastic members 121 that extend from one leg opening 103a to the other leg opening 103b and are spaced apart in the longitudinal direction L, between the first outer sheet 111 and the second outer sheet 113.
[0050] Each of the multiple rear opening elastic members 125, multiple rear body elastic members 119, and multiple rear leg elastic members 121 is joined to the first exterior sheet 111 and the second exterior sheet 113 by an internal joint 117 made of hot melt adhesive, while extended relative to the first exterior sheet 111 and the second exterior sheet 113.
[0051] The absorbent body 3 comprises a first absorbent body 5 that is irremovably attached to the panty-type sanitary napkin 1 (specifically, the outer casing 9), and a second absorbent body 7 that is removably attached to the panty-type sanitary napkin 1 (specifically, the first absorbent body 5). The first absorbent body 5 is positioned from the front waist area 11 through the crotch area 13 to the rear waist area 15. The second absorbent body 7 is positioned on the skin side of the first absorbent body 5 and in the front crotch area 13a and the rear crotch area 13b. For example, the first absorbent body 5 is positioned on the skin side of the crotch area 13, and the second absorbent body 7 is positioned on the skin side of the first absorbent body 7.
[0052] However, "non-removable" means that it is not intended to be removed under normal use, and "non-removable connection" means that it is connected in a way that prevents removal under normal use. "Removable" means that it is intended to be removed under normal use, and "removable connection" means that it is connected in a way that allows removal under normal use.
[0053] The above-mentioned removable joint and non-removable joint can be achieved by adjusting the joint strength between the second absorbent body 7 and the panty-type napkin 1 (e.g., the first absorbent body 5) and the joint strength between the first absorbent body 5 and the panty-type napkin 1 (e.g., the outer casing 9). For example, this can be achieved by (i) making the joint area between the second absorbent body 7 and the panty-type napkin 1 (e.g., the first absorbent body 5) smaller than the joint area between the first absorbent body 5 and the panty-type napkin 1 (e.g., the outer casing 9), (ii) making the joint strength per unit area between the second absorbent body 7 and the panty-type napkin 1 (e.g., the first absorbent body 5) smaller than the joint strength per unit area between the first absorbent body 5 and the panty-type napkin 1 (e.g., the outer casing 9), or (iii) a combination thereof.
[0054] The first absorbent body 5 has a first absorbent body front edge 21a, which is the edge closest to the front edge 17 of the first absorbent body 5, and a first absorbent body rear edge 21b, which is the edge closest to the rear edge 19 of the first absorbent body 5. The second absorbent body 7 has a second absorbent body front edge 23a, which is the edge closest to the front edge 17 of the second absorbent body 7, and a second absorbent body rear edge 23b, which is the edge closest to the rear edge 19 of the second absorbent body 7.
[0055] In the above-described unfolded state, the front edge 23a of the second absorbent body is positioned closer to the centerline WC in the width direction than the front edge 21a of the first absorbent body, and the rear edge 23b of the second absorbent body is positioned closer to the centerline WC in the width direction than the rear edge 21b of the first absorbent body.
[0056] The first absorbent body 5 includes a first absorbent body front end 25a, which is the end closer to the front edge 17 of the first absorbent body 5, and a first absorbent body rear end 25b, which is the end closer to the rear edge 19 of the first absorbent body 5. The second absorbent body 7 also includes a second absorbent body front end 27a, which is the end closer to the front edge 17 of the second absorbent body 7, and a second absorbent body rear end 27b, which is the end closer to the rear edge 19 of the second absorbent body 7.
[0057] The first absorbent body front end portion 25a refers to the region extending from the edge near the front edge 17 of the first absorbent body 5 to preferably within 30%, more preferably within 20%, and even more preferably within 10% of the longitudinal length L of the first absorbent body 5. The first absorbent body rear end portion 25b refers to the region extending from the edge near the rear edge 19 of the first absorbent body 5 to preferably within 30%, more preferably within 20%, and even more preferably within 10% of the longitudinal length L of the first absorbent body 5. The second absorbent body front end portion 27a refers to the region extending from the edge near the front edge 17 of the second absorbent body 7 to preferably within 30%, more preferably within 20%, and even more preferably within 10% of the longitudinal length L of the second absorbent body 7. The rear end portion 27b of the second absorbent body refers to a region extending from the edge near the rear end edge 19 of the second absorbent body 7, preferably within 30%, more preferably within 20%, and even more preferably within 10% of the longitudinal length L of the second absorbent body 7.
[0058] In the deployed state described above, the front end portion 25a of the first absorbent body is positioned closer to the front edge 17 than the front end portion 27a of the second absorbent body. Also, in the deployed state, the rear end portion 25b of the first absorbent body is positioned closer to the rear edge 19 than the rear end portion 27b of the second absorbent body.
[0059] The first absorbent body 5 comprises, in the thickness direction T, a liquid-permeable first top sheet 31, a first absorbent 35, a pair of hydrophobic nonwoven fabric sheets 43, a first absorbent body elastic member 41, and a liquid-impermeable first back sheet 39 in that order. The first top sheet 31 has a first skin-contact surface 33a and a first non-skin-contact surface 33b. The first absorbent 35 comprises a first absorbent core 37a and a first core wrap 37b covering the first absorbent core 37a. The first absorbent core 37a contains pulp fibers (not shown) and a superabsorbent polymer (not shown). Each of the pair of hydrophobic nonwoven fabric sheets 43 is folded over on the outside in the width direction W to make it double-layered and extends outward in the width direction W of the first absorbent body 35. The first back sheet 39 is preferably made of a moisture-permeable (breathable) film. A liquid diffusion sheet may be placed between the first top sheet 31 and the first absorbent 35, and a nonwoven fabric sheet, such as a hydrophobic nonwoven fabric sheet, may be placed on the non-skin side of the first back sheet 39. The first absorbent core 37a may have a pair of constrictions that are narrowed in the width direction.
[0060] The first absorbent core 37a and the first core wrap 37b are joined by a joint (not shown) made of hot melt adhesive. The first top sheet 31 and the first absorbent 35, specifically the first core wrap 37b, are joined by a top sheet-core wrap joint 131 made of hot melt adhesive. The first absorbent core 37a is preferably 50 g / m² 2 Above, a comfortable 100g / m 2 The above, and preferably 400 g / m² 2 More preferably 200g / m 2 It has the following basis weight.
[0061] The first top sheet 31 is positioned to cover the first absorber 35 (first absorbent core 37a and first core wrap 37b) and is bonded to each of the pair of hydrophobic nonwoven fabric sheets 43 at a top sheet nonwoven fabric joint 133 made of hot melt adhesive. The hydrophobic nonwoven fabric sheets 43 are made of hydrophobic nonwoven fabric.
[0062] The first absorbent body elastic member 41 is composed of a plurality of (for example, four) filamentous elastic members. The plurality of filamentous elastic members are arranged to extend along the longitudinal direction L from the front crotch region to the rear crotch region 13b. Furthermore, the plurality of filamentous elastic members constituting the first absorbent body elastic member 41 are spaced apart in the width direction W and arranged at a predetermined widthwise pitch. The first absorbent body elastic member 41 is joined to the first absorbent body 5 (first back sheet 39, hydrophobic nonwoven fabric sheet 43, first absorbent 35, etc.) by an elastic member joint 45 made of hot melt adhesive, with the plurality of filamentous elastic members stretched relative to the first absorbent body 5. The first absorbent body elastic member 41 is a member that facilitates the contact of the absorbent body 3, that is, the first absorbent body 5 and the second absorbent body 7, with the wearer's excretory opening.
[0063] Each of the pair of hydrophobic nonwoven fabric sheets 43 is folded inward to cover the absorbent body 3 (first absorbent body 5 and second absorbent body 7), forming a leak-proof wall 47. Thus, the pair of hydrophobic nonwoven fabric sheets 43 form a pair of leak-proof walls 47 on both outer sides in the width direction W of the absorbent body 3 (first absorbent body 5 and second absorbent body 7). Each of the pair of leak-proof walls 47 has a fixed end (not shown) that is fixed to the first absorbent body 35 and the first back sheet 39, and a free end (not shown) on the opposite side. In the unfolded state, each of the pair of leak-proof walls 47 has one or more (e.g., two) leak-proof wall elastic members 49 extending longitudinally L from the front waist region 11 through the crotch region 13 to the rear waist region 15 at the free end. Each of the one or more leak-proof wall elastic members 49 is extended relative to the leak-proof wall 47 (hydrophobic nonwoven fabric sheet 43) and joined to the hydrophobic nonwoven fabric sheet 43 within the folded hydrophobic nonwoven fabric sheet 43 by a joint (not shown) made of hot melt adhesive.
[0064] Each pair of leak-proof walls 47 is provided with a pair of front leak-proof wall joints 75 that connect the pair of leak-proof walls 47 to the first top sheet 31 in the front waist region 11. Furthermore, each pair of leak-proof walls 47 is provided with a pair of rear leak-proof wall joints 77 that connect the pair of leak-proof walls 47 to the first top sheet 31 in the rear crotch region 13b and the rear waist region 15.
[0065] The pair of leak-proof walls 47 are made of hydrophobic nonwoven fabric that forms the hydrophobic nonwoven fabric sheet 43, and are hydrophobic, and stand up from the absorbent body 3 when worn to suppress menstrual blood leakage. The first back sheet 39 is joined to the outer body 9, in particular the second outer sheet 113, by an inter-body joint 107 made of hot melt adhesive. As a result, the first absorbent body 5 is irremovably joined to the outer body 9 (shorts-type sanitary napkin 1).
[0066] The second absorbent body 7 comprises, in the thickness direction T, a liquid-permeable second top sheet 51, a second absorbent 55, and a liquid-impermeable second back sheet 59 in that order. The second top sheet 51 has a second skin-contact surface 53a and a second non-skin-contact surface 53b. The second absorbent 55 comprises a second absorbent core 57a and a second core wrap 57b covering the second absorbent core 57a. The second absorbent core 57a contains pulp fibers (not shown) and a superabsorbent polymer (not shown). The second back sheet 59 is made of a non-permeable (non-air-permeable) film. A liquid diffusion sheet may be placed between the second top sheet 51 and the second absorbent 55, and a nonwoven fabric sheet, such as a hydrophobic nonwoven fabric sheet, may be placed on the non-skin side of the second back sheet 59. The second absorbent core 57a may have a pair of constricted portions that are narrowed in the width direction.
[0067] The second absorbent core 57a and the second core wrap 57b are joined by a joint (not shown) made of hot-melt adhesive. The second top sheet 51 and the second absorbent 55, specifically the second core wrap 57b, are joined by a top sheet-core wrap joint 131 made of hot-melt adhesive. The second absorbent core is preferably 50 g / m². 2Above, a comfortable 100g / m 2 The above, and preferably 400 g / m² 2 More preferably 200g / m 2 It has the following basis weight.
[0068] The second top sheet 51 is positioned to cover the second absorbent 55 (second absorbent core 57a and second core wrap 57b), and is bonded to the second back sheet 59 together with the second absorbent 55 at a top sheet-back sheet joint 135 made of hot melt adhesive.
[0069] The panty-type sanitary napkin 1 is provided with alternating sections in the width direction W of body joints 61, where the second absorbent body 7 is detachably joined to the first absorbent body 5, and body non-joint sections 65, where the second absorbent body 7 is not joined to the first absorbent body 5. Therefore, the second absorbent body 7 is detachably joined to the first absorbent body 5 (panty-type sanitary napkin 1).
[0070] In other words, the second absorbent body 7 is positioned between the pair of leak-proof walls 47 of the first absorbent body 5 and the first top sheet 31, and is joined to the first top sheet 31 of the first absorbent body 5 by an inter-body joint 61 located on the second back sheet 59. However, the inter-body joint 61 is made of hot melt adhesive. The inter-body joint 61 is arranged to extend intermittently in the longitudinal direction L and comprises a plurality (for example, two) of inter-body joint portions 63 that are spaced apart in the width direction W. When there are two inter-body joint portions 61, specifically, there is one inter-body joint portion 63a and the other inter-body joint portion 63b. The one inter-body joint portion 63a and the other inter-body joint portion 63b are spaced apart in the width direction W and are arranged symmetrically with respect to the longitudinal center line LC. Each of the inter-body joint portions 63a and 63b is arranged in multiples (for example, three) at intervals (intermittently) along the longitudinal direction L.
[0071] In the region where the first absorbent body 5 and the second absorbent body 7 overlap in the thickness direction T, the portion other than the inter-body joint portion 61 (inter-body joint portion 63a and inter-body joint portion 63b), that is, the portion where the first absorbent body 5 and the second absorbent body 7 are not joined, is the inter-body non-joint portion 65. The inter-body non-joint portion 65 is located at least in the central and front part of the width direction W of the second absorbent body 7 (for example, the front crotch region 13a). Furthermore, the inter-body non-joint portion 65 is located at least in the central and rear part of the width direction W of the second absorbent body 7 (for example, the rear crotch region 13b).
[0072] The panty-type sanitary napkin 1 includes a front cover sheet 71 that is joined to the second outer sheet 113 and the first absorbent body 5 from the skin side of the panty-type sanitary napkin 1 so as to cover the front edge 21a of the first absorbent body in the front waist area 11, but not to cover the front edge 23a of the second absorbent body. Furthermore, the panty-type sanitary napkin 1 includes a rear cover sheet 73 that is joined to the second outer sheet 113 and the first absorbent body 5 from the skin side of the panty-type sanitary napkin 1 so as to cover the rear edge 21b of the first absorbent body in the rear waist area 15, but not to cover the rear edge 23b of the second absorbent body.
[0073] The second absorbent body 7 may include a surface bonding portion 91 that is positioned on the non-skin side surface and can be bonded to the skin side surface. The surface bonding portion 91 may be positioned, for example, between adjacent main body bonding portions 63a of a plurality of body bonding portions 63a, or between adjacent main body bonding portions 63a of a plurality of body bonding portions 63b. Alternatively, it may be positioned at any location within the non-bonding portion 65 between bodies. Examples of the surface bonding portion 91 include a hook tape with hooks of a hook-and-loop fastener, and an adhesive that can be bonded and peeled off. Note that the body bonding portion 61 may also function as the surface bonding portion 91.
[0074] As explained above, in the panty-type sanitary napkin 1, the second absorbent body 7 is detachably attached to the panty-type sanitary napkin 1 (first absorbent body 5). Therefore, the user of the panty-type sanitary napkin 1 can first allow the second absorbent body 7 to absorb bodily fluids, and then remove and discard the second absorbent body 7 that has absorbed the bodily fluids. This allows the first absorbent body 5 to absorb bodily fluids even after the second absorbent body 7 has been removed, while the panty-type sanitary napkin 1 is still being worn.
[0075] Furthermore, the materials used in each sheet can be known sheets that are available in the field of hygiene products.
[0076] Next, an example of the configuration of an individual packaging containing a panty-type absorbent article according to the embodiment will be described. Figure 9 is a diagram illustrating an individual packaging according to the embodiment, and is specifically a front view showing an example of the configuration of an individual packaging 201 containing a panty-type sanitary napkin 1B. In this example, the individual packaging 201 contains a panty-type sanitary napkin 1B, which is a folded panty-type sanitary napkin 1.
[0077] The individual packaging 201 comprises a panty-type sanitary napkin 1B having the above-described configuration and an individual packaging bag 202 which is a bag for containing the panty-type sanitary napkin 1B. Preferably, the individual packaging bag 202 is made of a non-breathable film material. In that case, it is possible to make it difficult for gaseous components inside the individual packaging bag 202 to escape to the outside.
[0078] The material for the individual packaging bag 202 is not particularly limited, as long as it can be used as an individual packaging bag in the field of hygiene products. Examples of such materials include synthetic resins such as polyethylene, polypropylene, and polyethylene terephthalate.
[0079] The individual packaging bag 202 includes a display section 206 on its outer surface, on which a design is depicted. The design may be a picture, pattern, or text, and the display section 206 displays a design 207a showing the first absorbent body 5 and the second absorbent body 7 stacked together. This allows the user to understand that in the panty-type sanitary napkin 1B inside the individual packaging bag 202, the second absorbent body 7 on the skin side is removable and can be disposed of separately. The display section 206 may display other designs. Other designs may include, for example, the product name 207b, instructions on how to use the product (not shown), and access information to a web page disclosing related information (not shown). Access information may include, for example, a QR code or a URL.
[0080] There are no particular restrictions on the method for forming the design of the display section 206, as long as it is usable as a design formation method in the field of hygiene products. Examples of such formation methods include known printing methods such as gravure printing, flexographic printing, offset printing, and inkjet printing, which involve printing with ink onto the sheet (component) that makes up the individual packaging bag 202.
[0081] The individual packaging bag 202 further includes a pair of transverse joints 203 and 204. The pair of transverse joints 203 and 204 seal the individual packaging bag 202. Specifically, the pair of transverse joints 203 and 204 seal the openings at both ends of the tubular sheet member for the individual packaging bag 202. Preferably, the individual packaging bag 202 further includes a longitudinal joint 205 extending from one of the transverse joints 203 and 204 to the other. In that case, the individual packaging body 201 is a pillow-type individual packaging body, which is easy to manufacture (package).
[0082] Figures 10 and 11 are diagrams illustrating an individual packaging according to an embodiment, and specifically, schematic diagrams showing an example of a method for manufacturing an individual packaging 201 of a panty-type sanitary napkin 1. Figure 10 is a schematic diagram showing an example of the folding process of the panty-type sanitary napkin 1. In this diagram, the longitudinal direction L, width direction W, and thickness direction T of the absorbent body 3 are applied similarly to the panty-type sanitary napkin 1. Figure 11 is a schematic diagram showing an example of the process of individually packaging the folded panty-type sanitary napkin 1B. In this diagram, the vertical direction is defined as the up-and-down direction, and the direction perpendicular to it is defined as the horizontal direction.
[0083] In the folding process, first, as shown in Figure 10(a), the panty-type napkin 1 is folded (tri-folded) along a pair of fold lines FL that pass through both outer sides in the width direction W of the absorbent body 3 and extend along the longitudinal direction L to form panty-type napkin 1A. Next, as shown in Figure 10(b), the panty-type napkin 1A is folded (bi-folded) along a fold line FW that passes through the center of the longitudinal direction L and extends along the width direction W to form panty-type napkin 1B.
[0084] Next, in the individual packaging process, first, the panty-type napkin 1B is placed on the sheet member 202A for the individual packaging bag 202, which extends in the vertical direction. Then, as shown in Figure 11(a), the sheet members 202A located on both outer sides of the panty-type napkin 1B in the horizontal direction are rolled inward to form a tube, enclosing the panty-type napkin 1B, thereby forming a vertical joint 205 that extends in the vertical direction (forming an intermediate body 201A of the individual packaging body 201). After that, as shown in Figure 11(b), in the tube-shaped sheet member enclosing the panty-type napkin 1B, a pair of horizontal joints 203 and 204 that extend in the horizontal direction are formed at the front and rear positions in the vertical direction of the panty-type napkin 1B. The molding method for each joint can be, for example, bonding with adhesive, welding with heat or ultrasonic waves, pressing with embossing or compression, or a combination thereof. Specifically, the pair of lateral joints 203 and 204 are welded, and the vertical joint 205 is adhesive. This allows for the production of pillow-shaped individual packaging 201.
[0085] The individual packaging 201 described above is merely an example, and its configuration (including the folding method and individual packaging method) is not particularly limited, as long as it includes at least a display section 206 and a pair of lateral joint sections 203 and 204.
[0086] Figures 12 and 13 are diagrams illustrating the individual packaging according to the embodiment, and specifically, schematic diagrams showing examples of the second absorbent body 7 after use being rolled up or otherwise placed in the individual packaging bag 202. Figure 12 is a schematic diagram showing an example of the second absorbent body 7 after use being rolled up, and Figure 13 is a schematic diagram showing an example of the second absorbent body 7 after use being folded.
[0087] When rolling up the second absorbent body 7, for example, first remove the second absorbent body 7 from the panty-type napkin 1. Then, as shown in Figures 12(a) and 12(b), roll up the second absorbent body 7, for example, with the rear edge 23b of the second absorbent body as the center, so that the second top sheet 51 is on the inside (the second back sheet 59 is on the outside). This will give you the second absorbent body 7A in a rolled-up state.
[0088] To fold the second absorbent body 7, for example, first remove the second absorbent body 7 from the panty-type napkin 1. Then, as shown in Figure 13, fold the second absorbent body 7 in the longitudinal direction L, for example, in thirds, so that the second top sheet 51 is on the inside (the second back sheet 59 is on the outside). This results in the folded second absorbent body 7B.
[0089] Thus, when the second absorbent body 7 is removed for disposal and rolled up with the second top sheet 51 on the skin side facing inward, the outer surface becomes a non-breathable film member positioned on the non-skin side, i.e., a non-breathable second back sheet 59. Therefore, when the second absorbent body is rolled up, leakage of odors related to bodily fluids from its outer surface can be suppressed.
[0090] Figures 14 and 15 are diagrams illustrating the individual packaging according to the embodiment, and specifically, schematic diagrams showing a method of disposing of the second absorbent body 7 in a rolled-up state using the individual packaging bag 202. Figure 14 is a schematic diagram showing an example of placing the second absorbent body 7 in a rolled-up state into the individual packaging bag 202, and Figure 15 is a schematic diagram showing an example of the second absorbent body 7 after use folded together with the individual packaging bag 202.
[0091] When the panty-type sanitary napkin 1 is used, for example, the lateral joint 203 of the individual packaging 201 is cut off, and the panty-type sanitary napkin 1 inside is removed. At that time, as shown in Figure 14(a), an opening 203A is formed in the individual packaging bag 202 from which the lateral joint 203 has been cut off. When the used second absorbent body 7 of the panty-type sanitary napkin 1 is disposed of, for example, as shown in Figure 14(b), the rolled-up second absorbent body 7A is placed into the individual packaging bag 202 through the opening 203A, and the opening 203A is folded to form a folded flap 203B, thereby closing the individual packaging bag 202.
[0092] In this way, in order to dispose of the second absorbent body 7, the second absorbent bodies 7A and 7B, which are in a rolled-up state, are inserted through the opening 203A of the individual packaging bag 202 and placed inside the individual packaging bag 202, making it easier to maintain the second absorbent bodies 7A and 7B in a rolled-up state. Furthermore, any odors that may be generated from the second absorbent bodies 7A and 7B can be contained within the individual packaging bag 202 and made less likely to spread.
[0093] Alternatively, when disposing of the used second absorbent body 7 in the panty-type sanitary napkin 1, all joints in the individual packaging bag 202, namely the pair of horizontal joints 203, 204 and the vertical joint 205, are opened in advance to make the individual packaging bag 202 into a roughly sheet state. Then, as shown in Figure 15, the roughly sheet-like individual packaging bag 202 and the second absorbent body 7 are placed on top of each other, with the second top sheet 51 of the second absorbent body 7 facing inward, and they are rolled up together, for example, around the rear edge 23b of the second absorbent body. This results in the second absorbent body 7C being rolled up together with the individual packaging bag 202. At this time, by positioning the vertical joint 205 on the outside so that it is rolled up last, the adhesive of the vertical joint 205 can be re-adhered to the rolled individual packaging bag 202.
[0094] In this way, when the second absorbent body 7 is rolled up together with the individual packaging bag 202 for disposal, the vertical joint 205 re-adheres, maintaining that state. This makes it possible to contain any odors that may be generated from the second absorbent body 7 within the individual packaging bag 202, making them less likely to spread. In addition, the second absorbent body 7 can be disposed of in a more compact form.
[0095] As described above, in this embodiment, the absorbent body 3 includes a first absorbent body 5 that is irremovably bonded to the absorbent article, and a second absorbent body 7 that is positioned on the skin side of the first absorbent body and is removably bonded to the absorbent article. The second absorbent body 7 includes a non-breathable film member (second backsheet 59) positioned on the non-skin side. The individual packaging bag 202 includes a display section 206 that displays a design 207a in which the first absorbent body 5 and the second absorbent body 7 are laminated, and a pair of lateral joints 203, 204 that seal the individual packaging bag 202.
[0096] Thus, in this individual packaging 201, the display section 206 of the individual packaging bag 202 shows a design 207a in which the first absorbent body 5 and the second absorbent body 7 are stacked, that is, a design in which the absorbent body 3 is double-layered. Therefore, the user can understand that in the panty-type sanitary napkin 1 inside the individual packaging bag 202, the second absorbent body 7 on the skin side is removable and can be disposed of separately. When the second absorbent body 7 on the skin side is removed for disposal and rolled up with the second top sheet 51 on the skin side facing inward, the outer surface becomes a non-breathable film member (second back sheet 59) positioned on the non-skin side. Therefore, when the second absorbent body 7 is rolled up, leakage of odors related to bodily fluids from its outer surface can be suppressed.
[0097] In addition, when using the panty-type napkin 1, for example, one of the pair of lateral joints 203, 204 can be torn open to open the individual packaging bag 202 and remove the panty-type napkin 1. When disposing of the second absorbent body 7, the second absorbent body 7, which is rolled up or otherwise in a rolled-up state, can be inserted into the opening 203A of the individual packaging bag 202 and stored in the individual packaging bag 202. The opening 203A can then be folded to form a folded flap 203B, thereby closing the individual packaging bag 202. This makes it easier to maintain the second absorbent body in a rolled-up state and suppresses the leakage of odors to the outside.
[0098] Therefore, when disposing of the removed second absorbent body 7, it is easier to maintain the rolled-up state, making it difficult for the generated odor to spread. Consequently, the risk of exposure of the second top sheet 51 and odor leakage is suppressed, reducing the embarrassment and guilt associated with disposing of the second absorbent body 7 in public restrooms, etc. Furthermore, the panty-type sanitary napkin 1 can be used easily for extended periods, and the second absorbent body 7 can be disposed of hygienically when removed.
[0099] In a preferred embodiment of this product, the individual packaging bag 202 is made of a non-permeable film material. Therefore, when disposing of the removed second absorbent body 7, placing the second absorbent body 7 in the individual packaging bag 202 can further suppress the leakage of odors to the outside and make them less likely to spread to the outside. Consequently, the embarrassment and guilt associated with disposing of the second absorbent body 7 in a public restroom or the like can be further reduced.
[0100] In a preferred embodiment of this product, the first absorbent body 5 includes a breathable film member (first backsheet 39) positioned on the non-skin side. Therefore, when the panty-type napkin 1 is worn, the moisture-laden air inside the panty-type napkin 1 can be released to the outside. This suppresses stuffiness inside the panty-type napkin 1. Furthermore, when disposing of the panty-type napkin 1 including the first absorbent body 5, it can be disposed of hygienically by being wrapped in a larger material including the rear waist area 15 and the front waist area 11.
[0101] In another aspect of this embodiment, the second absorbent body 7 includes a surface bonding portion 91 that is positioned on the non-skin side surface (second back sheet 59) and can be bonded to the skin side surface (second top sheet 51). Therefore, when the second absorbent body 7 is rolled up with its skin side (second top sheet 51 side) facing inward for disposal, the surface bonding portion 91 on the rolled-up non-skin side (second back sheet 59 side) can be bonded to the skin side surface. This allows the rolled-up state to be fixed. This makes it easier to maintain the second absorbent body 7 in the rolled-up state. Furthermore, it becomes possible to make it more difficult for the generated odor to diffuse.
[0102] In a preferred embodiment of this design, the individual packaging bag 202 further includes a vertical joint 205 extending from one of the pair of horizontal joints 203 and 204 to the other. Therefore, after opening one of the joints among the horizontal joints 203, 204 and the vertical joint 205 to remove the panty-type sanitary napkin 1, the shape of the individual packaging bag 202 is maintained by the other two joints. This allows the second absorbent body 7 to be easily stored in the individual packaging bag 202 when it is disposed of, such as in a rolled-up state. Furthermore, when all three horizontal joints 203, 204 and the vertical joint 205 are opened, the individual packaging bag 202 becomes substantially sheet-like. Therefore, when the second absorbent body 7 is rolled up together with the individual packaging bag 202, the vertical joint 205 re-adheres, maintaining that state. This allows the second absorbent body 7 to be disposed of in a more compact form.
[0103] In a preferred embodiment of this product, the shorts-type sanitary napkin 1 is provided with a plurality of front waist elastic members 115 in the front waist area 11, and is provided with alternating inter-body joining portions 61 and inter-body non-joint portions 65 in the width direction W, with the inter-body non-joint portions 65 being located in the central part of the width direction W and on the front side in the longitudinal direction L of the second absorbent body 7.
[0104] Thus, in this individual packaging 201, the second absorbent body 7 has a joint portion 61 between the bodies. Therefore, when the second absorbent body 7 is rolled up or otherwise disposed of, the joint portion 61 re-adheres, making it easier to maintain the rolled-up state. In addition, in this individual packaging 201, the joint portion 61 and the non-joint portion 65 between the bodies are provided alternately. As a result, the first absorbent body 5 contracts in the width direction W along with the front waist elastic member 115, making it easier for the second absorbent body 7 to lift up. Consequently, the user can easily pinch the lifted second absorbent body 7 with their fingers. This allows the user to easily fine-tune the position of the second absorbent body 7 when wearing it, improving the fit. Furthermore, the user can easily remove the second absorbent body 7 when disposing of it.
[0105] In a preferred embodiment of this product, the shorts-type sanitary napkin 1 is provided with a plurality of rear waist elastic members 119 in the rear waist region 15, and is provided with alternating inter-body joining portions 61 and inter-body non-joint portions 65 in the width direction W, with the inter-body non-joint portions 65 being located in the central part of the width direction W and on the rear side in the longitudinal direction L of the second absorbent body 7.
[0106] Thus, in this individual packaging 201, the second absorbent body 7 has a joint portion 61 between the bodies. Therefore, when the second absorbent body 7 is rolled up or otherwise disposed of, the joint portion 61 between the bodies re-adheres, making it easier to maintain the rolled-up state. In addition, in this individual packaging 201, the joint portions 61 between the bodies and the non-joint portions 65 between the bodies are provided alternately. As a result, the first absorbent body 5 contracts in the width direction W along with the rear waist elastic member 119, making it easier for the second absorbent body 7 to lift up. Therefore, the user can easily pinch the lifted second absorbent body 7 with their fingers. This allows the user to easily fine-tune the position of the second absorbent body 7 when wearing it, improving the fit. Furthermore, the user can easily remove the second absorbent body 7 when disposing of it.
[0107] In a preferred embodiment of this product, the front edge 21a of the first absorbent body 5 is positioned closer to the front edge 17 than the front edge 23a of the second absorbent body 7. The panty-type napkin 1 further includes a front cover sheet 71 that covers the front edge 21a of the first absorbent body but does not cover the front edge 23a of the second absorbent body.
[0108] Thus, in this individual packaging 201, the panty-type napkin 1 is equipped with a predetermined front cover sheet 71. Therefore, while wearing the panty-type napkin 1, the front cover sheet 71 covers the front edge 21a of the first absorbent body, making it less likely for leakage to occur at the front edge 21a of the first absorbent body. Furthermore, when removing the second absorbent body 7, the front cover sheet 71 does not cover the front edge 23a of the second absorbent body, making it easier to remove the second absorbent body 7 and dispose of it by rolling it up or other means.
[0109] In a preferred embodiment of this product, the rear edge 21b of the first absorbent body 5 is positioned closer to the rear edge 19 than the rear edge 23b of the second absorbent body 7. The panty-type napkin 1 further includes a rear cover sheet 73 that covers the rear edge 21b of the first absorbent body but does not cover the rear edge 23b of the second absorbent body.
[0110] Thus, in this individual packaging 201, the panty-type napkin 1 is equipped with a predetermined rear cover sheet 73. Therefore, while wearing the panty-type napkin 1, the rear cover sheet 73 covers the rear edge 21b of the first absorbent body, making it less likely for leakage to occur at the rear edge 21b of the first absorbent body. Furthermore, when removing the second absorbent body 7, the rear cover sheet 73 does not cover the rear edge 23b of the second absorbent body, making it easy to remove the second absorbent body 7 and dispose of it by rolling it up or the like.
[0111] (Second Embodiment) The packaging for the pant-type absorbent article according to this embodiment will now be described. The pant-type absorbent article in this embodiment is the same as in the first embodiment. These pant-type absorbent articles may or may not be stored in individual packaging bags, as in the first embodiment. The individual packaging bags for storage may be the same as in the first embodiment, or different individual packaging bags may be used.
[0112] Next, an example of the configuration of a packaging body containing the pant-type absorbent article according to the embodiment will be described. Figure 16 is a diagram illustrating the packaging body 301 according to the embodiment, and is a perspective view showing an example of the configuration of a packaging body 301 containing multiple panty-type sanitary napkins or multiple individual packages.
[0113] The packaging 301 has a width direction D1, a depth direction D2, and a vertical direction D3 that are perpendicular to each other. The packaging 301 comprises a plurality of panty-type sanitary napkins 1 (or 1B) or a plurality of individual packaging 201 (hereinafter also simply referred to as "a plurality of panty-type sanitary napkins 1 etc.") (neither of which are shown in the figures), and a package 302 that contains the plurality of panty-type sanitary napkins 1 etc. Note that the panty-type sanitary napkins 1 (or 1B) may be enclosed in individual packaging bags other than the individual packaging bags 202.
[0114] The packaging 301 (package 302) includes a front section 311, a rear section 312, a right section 313, and a left section 314 located on the sides, a top section 315 located on the top, a bottom section 316 located on the bottom, and a handle section 317. The direction from one of the front section 311 and the rear section 312 to the other is the depth direction D2. The direction from one of the right section 313 and the left section 314 to the other is the width direction D1. The direction from one of the top section 315 and the bottom section 316 to the other is the up-down direction D3.
[0115] In this embodiment, the package 302 is composed of a sheet member made of a synthetic resin such as polyethylene, polypropylene, or polyethylene terephthalate. Multiple panty-type sanitary napkins 1 etc. are contained in the package 302 in a vertical or horizontal position. However, the method of containing multiple panty-type sanitary napkins 1 etc. in the package 302 is not particularly limited and is arbitrary. The shape of the package 302 is not limited to the example shown in the figure, as long as it can be used for packaging absorbent articles or their individual packaging bags in the field of hygiene products.
[0116] Package 302 includes a product label section 306 on its outer surface, which has a design. The design may be a picture, pattern, or text, and the product label section 306 displays a design 307a showing the first absorbent body 5 and the second absorbent body 7 stacked together. This allows the user to understand that in the panty-type sanitary napkin 1, etc., inside package 302, the second absorbent body 7 on the skin side is removable and can be disposed of separately. The product label section 306 may display other designs. Other designs may include, for example, the product name 307b, instructions on how to use the product (not shown), and access information to a web page disclosing related information (not shown). Access information may include, for example, a QR code or a URL.
[0117] Thus, in the packaging 301, the product display section 306 of the package 302 shows a design in which the first absorbent body 5 and the second absorbent body 7 are stacked, that is, a design in which the absorbent body 3 is made up of two layers. Therefore, the user can understand that in the shorts-type napkin 1 (absorbent item) inside the package 302, the second absorbent body 7 on the skin side is removable and can be disposed of separately. When the second absorbent body 7 on the skin side is removed for disposal and rolled up with the second top sheet 51 on the skin side facing inward, the outer surface becomes a non-breathable film material (second back sheet 59) positioned on the non-skin side. Therefore, when the second absorbent body 7 is rolled up, leakage of odors related to bodily fluids from its outer surface can be suppressed.
[0118] In addition, when using the panty-type napkin 1 (absorbent item), for example, one of the pair of lateral joints 203, 204 can be torn to open the individual packaging bag 202 and remove the panty-type napkin 1. When disposing of the second absorbent body 7, the second absorbent body 7, which is rolled up or otherwise in a state, can be inserted through the opening of the individual packaging bag 202 and stored in the individual packaging bag 202. This makes it easier to maintain the second absorbent body 7 in a rolled-up or otherwise in a state, and also suppresses the leakage of any odors to the outside.
[0119] Therefore, when disposing of the removed second absorbent body 7, it is easier to maintain the rolled-up state, making it difficult for the generated odor to spread. Consequently, the risk of exposure of the second top sheet 51 and odor leakage is suppressed, reducing the embarrassment and guilt associated with disposing of the second absorbent body 7 in public restrooms, etc. Furthermore, the panty-type sanitary napkin 1 can be used easily for extended periods, and the second absorbent body 7 can be disposed of hygienically when removed.
[0120] In this specification, the direction along the longitudinal direction means that it is within ±45° of the longitudinal direction. The direction along the longitudinal direction is preferably within ±30°, more preferably within ±20°, even more preferably within ±10°, even more preferably within ±5°, and even more preferably parallel to the longitudinal direction.
[0121] In this specification, the region where A and B overlap in the X direction means the region where A and B overlap in a plan view from the X direction. In this specification, "inside" and "outside" in the width direction mean the side closer to the longitudinal centerline and the side further from the longitudinal centerline, respectively.
[0122] The individual packaging and packaging of the present invention are not limited to the embodiments described above, and appropriate combinations and modifications of the technologies described in each embodiment and known technologies are possible without departing from the purpose and spirit of the present invention.
