Summary of the Invention
Problems to be Solved by the Invention
[0004] Although the urine absorption pad (belly wrap type diaper) as described above gives a sense of security to users such as pet owners, some owners who value appearance (looks) may have a resistance to using such a diaper. Therefore, in recent years, a usage form in which such a diaper is worn inside a cloth wearing article (outer) has been proposed by the inventors. According to such a usage form, it is possible to achieve both the sense of security provided by the diaper and the enjoyment of fashion by the appearance of the wearing article.
[0005] On the other hand, in this type of use, it is conceivable to provide an engaging member, such as an adhesive, on the non-skin side of the absorbent item to secure it to the inside of the garment. However, with a belly band-type garment, due to the pet's body structure and active movements, the garment and the absorbent item inside it may shrink in the front-to-back direction, and there is a risk that part of the garment may get trapped between the absorbent item and the pet's body. For this reason, if an engaging member is provided on the non-skin side of the absorbent item, particularly in the longitudinal center, when the garment shrinks as described above, the exposed, different parts of the engaging member may unintentionally adhere to each other, resulting in what is known as "self-adhesion." Once self-adhesion occurs, even if the garment is stretched in the torso direction, the inner absorbent item will remain in a wrinkled state due to the self-adhesion. If this state persists, part of the garment may get trapped between the absorbent item and the pet's body, and there is a risk that the garment may become contaminated with urine or other excrement.
[0006] This disclosure aims to provide an absorbent article for pets that can suppress contamination of wearable items. [Means for solving the problem]
[0007] One form of absorbent article is an absorbent article used attached to a pet wearable item worn around the body of a pet, and comprises a main body having a circumferential direction that follows the body of the pet when the wearable item is worn by the pet, and a front-to-back direction perpendicular to the circumferential direction, the main body having a surface sheet placed on the side facing the pet's skin, a back sheet placed on the non-skin side opposite to the skin side, an absorbent material placed between the surface sheet and the back sheet, and a fixing member provided on the non-skin side of the back sheet for fixing the main body to the wearable item, one part of the fixing member being configured to be fixed to the other part of the fixing member when it comes into contact with the other part of the fixing member, the fixing member being provided in at least one pair of outer body regions when the main body is divided into three equal parts in the circumferential direction into a central body region and a pair of outer body regions outside the central body region, and the fixing member not being provided in the central region where the front-to-back central region and the central body region overlap when the main body is divided into three equal parts in the front-to-back direction. [Effects of the Invention]
[0008] According to this disclosure, it is possible to provide absorbent articles for pets that can suppress contamination of wearable items. [Brief explanation of the drawing]
[0009] [Figure 1] This is a plan view of an absorbent article according to one embodiment, as seen from the skin-facing side. [Figure 2] Figure 1 is a plan view of the absorbent material as seen from the non-skin side. [Figure 3] This is a schematic diagram showing the cross-sectional structure of the absorbent article along line III-III in Figure 1. [Figure 4] This is a schematic diagram showing the cross-sectional structure of the absorbent material common to the IVa-IVa and IVb-IVb lines in Figure 1. [Figure 5] Figure 1 is a plan view of a wearable item with an absorbent material attached, as seen from the skin side. [Figure 6] Figure 1 is a schematic diagram showing how the wearable item with the absorbent material attached is fitted around the body of a pet. [Figure 7] This is a plan view of the absorbent article according to the first modified example, as seen from the non-skin side. [Figure 8] This is a plan view of the absorbent article according to the second modified example, as seen from the non-skin side. [Modes for carrying out the invention]
[0010] This specification and the accompanying drawings will make at least the following aspects clear.
[0011] [1] An absorbent article used attached to a pet wearable item that is worn around the body of a pet, comprising a main body having a body direction that follows the body of the pet when the wearable item is worn on the pet, and a front-to-back direction perpendicular to the body direction, The main body is, A surface sheet placed on the skin side of the pet, A back sheet is positioned on the non-skin side, opposite to the skin side, An absorbent disposed between the surface sheet and the back sheet, The back sheet has a fixing member provided on the non-skin side for fixing the main body to the wearable item, One portion of the fixing member is configured to be fixed to the other portion of the fixing member when it comes into contact with the other portion of the fixing member. The fixing member is provided in at least each of the pair of outer regions of the torso when the main body is divided into three equal parts in the direction of the torso: the central region of the torso and a pair of outer regions of the torso outside the central region of the torso. The aforementioned fixing member is not provided in the central region where the front-to-rear central region and the torso central region overlap when the main body is divided into three equal parts in the front-to-rear direction, and the absorbent article is not provided in that central region.
[0012] According to the above configuration, the fixing members having the property of adhering to each other are not provided in the central region of the main body portion, but are provided in a pair of circumferential outer regions in the circumferential direction. Thereby, while ensuring a stable fixing force to the wearing article, in the central region where the wearing article and the absorbent article inside thereof are most likely to be affected by shrinking in the front-rear direction due to the movement of the pet, the occurrence of "self-adhesion" where the fixing members adhere to each other can be effectively prevented. Therefore, it is possible to suppress a part of the wearing article from entering between the absorbent article and the pet's body due to the state where the absorbent article remains shrunk in the front-rear direction. As a result, it is possible to suppress the wearing article from being contaminated with excrement such as urine.
[0013] [2] The absorbent article according to [1], wherein the fixing member is not provided in the circumferential central region.
[0014] According to the above configuration, since the non-fixing region where the fixing member is not provided extends over the entire strip-shaped region (circumferential central region) extending in the front-rear direction, the occurrence of the above-described self-adhesion can be suppressed more effectively.
[0015] [3] The absorbent article according to [2], wherein the fixing member is not provided in the two central regions when the main body portion is divided into four equal parts in the circumferential direction.
[0016] According to the above configuration, the non-fixing region where the fixing member is not provided can be further widened and secured from 1 / 3 to 1 / 2 of the length in the circumferential direction. Thereby, even when large wrinkles or deformations occur in the absorbent article, the occurrence of self-adhesion of the fixing member can be more reliably suppressed.
[0017] [4] The absorbent article according to any one of [1] to [3], wherein the fixing member is an adhesive member having an adhesive force.
[0018] According to the above configuration, by using a fixing member that is easily self-adhered due to its adhesive properties, and by adopting a configuration in which the fixing member is not provided in the central region as described above, it is possible to easily fix absorbent articles to wearable articles while effectively suppressing the occurrence of self-adhesion.
[0019] [5] The surface of the back sheet on the non-skin side is made of a film, as described in [4].
[0020] According to the above configuration, when a fixing member, which is an adhesive member, is provided with a release sheet on the surface (adhesive side) of the adhesive member before use, the adhesive member can be left cleanly on the film surface when the release sheet is peeled off. If the non-skin side surface of the back sheet is made of a fuzzy nonwoven fabric or the like, there is a risk that a part of the adhesive member will peel off together with the release sheet when the release sheet is peeled off. According to the above configuration, this problem can be avoided, and as a result, stable adhesive performance to wearable items can be ensured.
[0021] [6] The fixing member has a portion that overlaps with the absorbent in the thickness direction perpendicular to the front-rear direction and the circumference direction, according to any one of [1] to [5].
[0022] According to the above configuration, the rigidity of the region where the fixing member is provided is increased by the presence of the absorber. This suppresses twisting and bending in that region, and more effectively suppresses self-adhesion of the fixing member placed in the region where the fixing member and the absorber overlap. Furthermore, since the absorber and the fixing member are fixed together to the wearable item in that region, displacement of the absorber can be more effectively suppressed.
[0023] [7] The fixing member is composed of a plurality of parts that are spaced apart in the front-rear direction, as described in any of [1] to [6].
[0024] With the above configuration, compared to the case where a fixed member extending in the front-to-back direction is provided, the flexibility of the absorbent article in the front-to-back direction can be increased by the region between multiple parts in the front-to-back direction (i.e., the non-fixed region where no fixed member exists). As a result, the absorbent article can flexibly follow the movements of the pet as it curls up or stretches its body. Therefore, the feeling of stiffness and tension when wearing it is reduced, and the comfortable wearing experience for the pet can be further improved.
[0025] [8] The width of the fixing member in the direction of the waist is 50 mm or less, as described in any of [1] to [7].
[0026] According to the above configuration, it is possible to suppress the area of the fixing member from becoming excessive, and further reduce the risk of self-adhesion when the absorbent material becomes distorted.
[0027] [9] At least a portion of the fixing member is positioned within 15 mm from the edge of the absorbent in the circumferential direction, as described in any of [1] to [8].
[0028] According to the above configuration, the vicinity of the end of the absorbent material, which has relatively high rigidity, in the direction of the torso can be firmly fixed to the garment being worn. This makes it possible to maintain a stable attachment state of the absorbent material to the garment being worn.
[0029] [Embodiment] Embodiments of this disclosure will be described in detail below with reference to the drawings. In the following description, the same reference numerals will be used for identical or equivalent elements, and redundant explanations will be omitted. The drawings may be simplified or exaggerated in part for ease of understanding, and the dimensional ratios are not limited to those shown in the drawings.
[0030] The following describes an absorbent article 1 according to one embodiment. Figure 1 is a plan view of the absorbent article 1 according to one embodiment, viewed from the skin side Z1. Figure 2 is a plan view of the absorbent article 1, viewed from the non-skin side Z2. Figure 3 is a schematic diagram showing the cross-sectional structure of the absorbent article 1 along line III-III in Figure 1. In Figure 3, the front leak-proof wall portion 20 and the rear leak-proof wall portion 30 are shown in an upright position. Figure 4 is a schematic diagram showing the cross-sectional structure of the absorbent article 1 common to lines IVa-IVa and IVb-IVb in Figure 1. In Figure 4, the fixing members 11 and 12 provided on the surface 4a of the back sheet 4 are not shown. Figure 5 is a plan view of the wearable article 100 to which the absorbent article 1 is attached, viewed from the skin side Z1. Figure 6 is a schematic diagram showing how the wearable article 100 to which the absorbent article 1 is attached is attached to the body of a pet.
[0031] In this specification, “pet” refers to the animal to which the absorbent article 1 is intended to be used (i.e., the animal to which the wearable article 100 to which the absorbent article 1 is attached is worn). Pets broadly include vertebrates and invertebrates, and typically include companion animals such as dogs, cats, rabbits, and hamsters. In this embodiment, the animal to which the wearable article 100 is worn is a male dog.
[0032] Figures 1 and 2 show the absorbent article 1 in an unfolded state, stretched to a wrinkle-free state. As shown in Figures 1 and 2, the absorbent article 1 has, for example, a rectangular shape. As shown in Figures 5 and 6, the absorbent article 1 is used by being attached to the inside of a wearable article 100 that is wrapped around the body of a pet.
[0033] The absorbent article 1 comprises a main body 2. The main body 2 has a direction D1 circumferential torso and a front-to-back direction D2 perpendicular to the circumferential torso direction D1. That is, the main body 2 extends in the circumferential torso direction D1 and the front-to-back direction D2. The circumferential torso direction D1 is the direction along the waist of the pet when the wearable article 100 to which the absorbent article 1 is attached is worn on the pet, as shown in Figure 6.
[0034] In this specification, for convenience, in the unfolded state shown in Figures 1 and 2, the direction parallel to the front-to-back direction D2 is referred to as the X-axis direction, the direction parallel to the waist circumference direction D1 is referred to as the Y-axis direction, and the direction parallel to the thickness direction D3, which is perpendicular to the waist circumference direction D1 and the front-to-back direction D2, is referred to as the Z-axis direction. In this specification, "skin-facing side Z1" is the side of the absorbent article 1 that faces the pet's skin when it is worn on the pet together with the wearable article 100. "Non-skin-facing side Z2" is the side that faces away from the pet's skin when it is worn.
[0035] As shown in Figures 1 to 4, the main body 2 has a front sheet 3, a back sheet 4, an absorbent 5, a front sheet 6, and a rear sheet 8. The front sheet 6 is a sheet provided on the side that is in front of the pet when worn, and the rear sheet 8 is a sheet provided on the side that is in rear of the pet when worn. In other words, the absorbent article 1 of this embodiment is intended to be attached to the wearable item 100 so that the side with the front sheet 6 is in front and the side with the rear sheet 8 is in the rear, and then worn around the body of the pet.
[0036] The surface sheet 3 constitutes the surface of the main body 2 that comes into contact with the pet and is positioned on the skin side Z1. The surface sheet 3 is permeable to liquids, for example, allowing the pet's urine to pass through to the absorbent material 5. The surface sheet 3 can be formed from, for example, a nonwoven or woven fabric with liquid permeability, a synthetic resin film with liquid permeability holes, or a composite sheet thereof. In this embodiment, the surface sheet 3 is positioned over the entire skin side Z1 of the main body 2 and has a folded portion 31 that is folded back at the front end E1 of the main body 2. The folded portion 31 constitutes a part of the front leak-proof wall portion 20, which will be described later.
[0037] The back sheet 4 is located on the main body 2, facing the skin-facing side Z1 of the wearable article 100, and positioned on the non-skin-facing side Z2. The back sheet 4 can be made of, for example, a liquid-impermeable nonwoven fabric, a synthetic resin film, or a composite sheet thereof. In this embodiment, the back sheet 4 is a leak-proof sheet made of a liquid-impermeable synthetic resin film. The back sheet 4 is folded back at its front end E1 towards the skin-facing side Z1 and includes a folded portion 41 that constitutes at least a part of the front leak-proof wall portion 20, which will be described later.
[0038] The absorbent body 5 is positioned between the surface sheet 3 and the back sheet 4. The absorbent body 5 absorbs pet urine. For example, the absorbent body 5 is formed in a rectangular shape, with a length D1 in the circumference direction longer than the length D2 in the front-to-back direction. For example, the absorbent body 5 may include an absorbent core and a core wrap that covers the surface of the absorbent core. The absorbent core may include, for example, water-absorbent pulp or a superabsorbent polymer (SAP), or a mixture thereof. The core wrap is, for example, tissue or a nonwoven fabric sheet. In this embodiment, the external shape of the absorbent core as viewed from the thickness direction D3 is substantially the same as the external shape of the absorbent body 5. As shown in Figures 1 and 3, for example, the front end 5a of the absorbent body 5 is positioned along the front end E1 of the main body 2. On the other hand, the rear end 5b of the absorbent body 5 is positioned forward and separated from the rear end E2 of the main body 2.
[0039] The main body 2 includes a front leak-proof wall section 20 and a rear leak-proof wall section 30.
[0040] The front leak-proof wall portion 20 is composed of the folded portion 31 of the surface sheet 3, the folded portion 41 of the back sheet 4, and the front sheet 6. As shown in Figure 3, the front sheet 6 is joined to the skin side Z1 of the folded portion 31 of the surface sheet 3. The front sheet 6 is folded in half, and the folded portion (the portion where the elastic member 7 is provided, as will be described later) constitutes the top portion 20a of the front leak-proof wall portion 20. The front sheet 6 is provided over the entire area of the main body portion 2 in the circumference direction D1. The front sheet 6 is, for example, a nonwoven fabric sheet. The folded portion 41 of the back sheet 4 is joined to cover the surface of the non-skin side Z2 of the folded portion 31 of the surface sheet 3 and a part of the surface of the non-skin side Z2 of the front sheet 6.
[0041] The front leak-proof wall portion 20 is configured such that the portion between the pair of fixing portions R1 provided on both sides in the circumferential direction D1 at the front end E1 of the main body portion 2 rises up with the front end E1 as the pivot point. As shown in Figure 4, each fixing portion R1 is the portion where the skin-side Z1 surface of the front leak-proof wall portion 20 (in this embodiment, the surface of the front sheet 6) and the skin-side Z1 surface 3a of the surface sheet 3 are joined (fixed). As shown in Figure 1, in this embodiment, the pair of fixing portions R1 are provided at both ends in the circumferential direction D1 along the front end E1, and are each provided in a rectangular shape.
[0042] With the above-described configuration, the portion of the front leak-proof wall 20 between the pair of fixing portions R1 is configured to rise up with the front end portion E1 as the pivot point. Furthermore, in this embodiment, in order to facilitate the rising of the front leak-proof wall 20, as shown in Figures 1 and 3, the front leak-proof wall 20 is provided with an elastic member 7 that expands and contracts in the direction of the body circumference D1, in a predetermined range including at least the central part of the main body portion 2 in the direction of the body circumference D1. The elastic member 7 is, for example, elastic thread. As an example, the elastic member 7 is sandwiched in the front sheet 6 at the folded portion of the front sheet 6.
[0043] The rear leak-proof wall portion 30 is composed of a rear sheet 8. As shown in Figure 3, the rear sheet 8 is provided along the rear end E2 of the main body portion 2 and covers the entire area of the main body portion 2 in the circumferential direction D1. The rear edge of the rear sheet 8 coincides with the rear end E2 of the main body portion 2. As an example, the leading edge of the rear sheet 8 is folded back to the skin side Z1. An elastic member 9 that expands and contracts in the circumferential direction D1 is provided between the folded rear sheet 8. In this embodiment, the elastic member 9 is located near the top 30a of the rear leak-proof wall portion 30. The elastic member 9 is, for example, a thread elastic similar to the elastic member 7.
[0044] The rear leak-proof wall portion 30 is joined (fixed) to the surface 3a of the surface sheet 3 by a pair of fixing portions R2 and R3. The pair of fixing portions R2 are provided at both ends in the circumferential direction D1 along the rear end E2, and are each provided in a rectangular shape. The fixing portion R3 is provided between the pair of fixing portions R2, extending in the circumferential direction D1 along the rear end E2, in a rectangular shape. The front-to-back width of fixing portion R3 is smaller than the front-to-back width of each fixing portion R2.
[0045] With the above-described configuration, the portion of the rear leak-proof wall 30 between the pair of fixing parts R2 and inside (front of) the fixing part R3 is configured to rise up with the front end edge of the fixing part R3 as the upright support point 30b.
[0046] As shown in Figure 2, fixing members 11 and 12 are provided on the surface 4a (the non-skin side Z2) of the back sheet 4. The fixing members 11 and 12 are provided along both side edges of the main body 2 in the waist direction D1 and extend in the front-rear direction D2. The fixing members 11 and 12 are provided in a rectangular shape with the front-rear direction D2 as the longitudinal direction.
[0047] The fixing members 11 and 12 are made of a self-adhering material. Self-adhesion means that "when one part of the fixing member 11 or 12 comes into contact with another part of the fixing member 11 or 12, it is configured to be fixed to that other part." For example, the fixing members 11 and 12 are adhesive members made of an adhesive such as hot melt adhesive (HMA). In this case, self-adhesion of the fixing members 11 and 12 means that when the adhesive surface of the one part and the adhesive surface of the other part come into contact with each other, these parts are fixed together by adhesive. Note that the above "self-adhesion" includes not only cases where different parts within the same fixing member are fixed together, but also cases where parts of different fixing members (for example, a part of fixing member 11 and a part of fixing member 12) are fixed together.
[0048] As shown in Figure 5, the absorbent article 1 is attached to the wearable article 100 via fixing members 11 and 12. The wearable article 100 has an inner surface 100a to which the absorbent article 1 is attached, and an outer surface 100b. Furthermore, the wearable article 100 is formed such that, as an example, the front-to-back width increases towards the inside in the waist direction D1, and has the greatest front-to-back width at the center in the waist direction D1. The wearable article 100 has a central region P1 with a relatively large front-to-back width including the center in the waist direction D1, and a pair of end regions P2 and P3 located on both sides of the central region P1 in the waist direction D1. The absorbent article 1 is attached to the central region P1. In this embodiment, the absorbent article 1 is attached to the inner surface 100a of the wearable article 100 in the central region P1 via the respective fixing members 11 and 12. The respective end regions P2 and P3 are regions that are fixed to each other so as to maintain the wearable article 100 in a state attached to the waist of the pet.
[0049] A fixing member 101 is provided on the inner surface 100a of one end region P2. The fixing member 101 is provided in a rectangular shape that extends in the front-rear direction D2 along the edge of the end region P2 opposite to the central region P1 side. As an example, the fixing member 101 is provided with multiple loop portions.
[0050] A fixing member 102 is provided on the outer surface 100b of the other end region P3. The fixing member 102 is provided in a rectangular shape extending in the front-rear direction D2 along the edge of the end region P3 opposite to the central region P1 side. For example, the circumference width of the fixing member 102 (length along the circumference direction D1) is larger than the circumference width of the fixing member 101. For example, the fixing member 102 is provided with multiple hook portions that engage with multiple loop portions of the fixing member 101. In this way, the fixing member 101 and the fixing member 102 are configured to be able to be joined and detached by bringing their surfaces together. Note that the fixing member 101 may be provided with multiple hook portions, and the fixing member 102 may be provided with multiple loop portions.
[0051] As shown in Figure 6, the wearable item 100 to which the absorbent item 1 is attached is wrapped around the pet's body such that the front end E1 of the absorbent item 1 is positioned forward and the absorbent item 1 is positioned below the pet. The wearable item 100 is then attached to the pet's body by fixing the fixing member 101 to the fixing member 102.
[0052] Referring to Figure 2, the arrangement of the fixing members 11 and 12 of the absorbent article 1 will be described in detail. In Figure 2, X1, X2, and X3 represent the first, second, and third regions from the front when the main body 2 is divided into three equal parts in the front-rear direction D2. Hereinafter, these regions will be referred to as the front region X1, the front-rear central region X2, and the rear region X3. In Figure 2, Y11, Y12, and Y13 represent the first, second, and third regions from one end (edge E3) when the main body 2 is divided into three equal parts in the waist direction D1. Hereinafter, these regions will be referred to as the waist central region Y12 and the pair of waist outer regions Y11 and Y13 outside the waist central region Y12.
[0053] As shown in Figure 2, the fixing members 11 and 12 are provided in a pair of outer girth regions Y11 and Y13. In this embodiment, fixing member 11 is provided in outer girth region Y11, and fixing member 12 is provided in outer girth region Y13. Fixing members similar to fixing members 11 and 12 are not provided in the central region A1 when the main body 2 is divided into three equal parts in the girth direction D1 and the front-rear direction D2. The central region A1 is the region where the front-rear central region X2 and the girth central region Y12 overlap.
[0054] [Effects and Effects] In the absorbent article 1 having the above-described configuration, the fixing members 11 and 12, which have the property of adhering to each other, are not provided in the central region A1 of the main body 2, but are provided in a pair of outer regions Y11 and Y13 around the body in the direction D1. This ensures a stable fixing force to the wearable article 100, while effectively preventing the occurrence of "self-adhesion," where the fixing members 11 and 12 stick to each other, in the central region A1, which is most susceptible to the effects of the wearable article 100 and the absorbent article 1 inside it contracting in the front-to-back direction D2 due to the pet's movement. Therefore, it is possible to suppress the occurrence of a part of the wearable article 100 getting between the absorbent article 1 and the pet's body due to the absorbent article 1 remaining contracted in the front-to-back direction D2. As a result, it is possible to suppress contamination of the wearable article 100 with urine and other excrement.
[0055] As shown in Figure 2, in this embodiment, fixing members similar to fixing members 11 and 12 are not provided in the central region Y12 of the girth. That is, fixing members are not provided not only in the central region A1, but also in the regions in front of and behind the central region A1 in the front-rear direction D2 (i.e., regions belonging to the front region X1 or the rear region X3). With the above configuration, the non-fixed region where fixing members 11 and 12 are not provided extends across the entire band-shaped region (i.e., the central region Y12 of the girth) extending in the front-rear direction D2, so that the occurrence of self-adhesion described above can be suppressed even more effectively.
[0056] In Figure 2, Y21, Y22, Y23, and Y24 represent the first, second, third, third, and fourth regions from one end (edge E3) when the main body 2 is divided into four equal parts in the circumference direction D1. As shown in Figure 2, in this embodiment, fixing members similar to fixing members 11 and 12 are not provided in the two central regions Y22 and Y23 when the main body 2 is divided into four equal parts in the circumference direction D1. That is, fixing members 11 and 12 are provided only in the outer regions Y21 and Y24 when the main body 2 is divided into four equal parts in the circumference direction D1. With the above configuration, the non-fixed region where no fixing members are provided can be further extended from 1 / 3 of the length in the circumference direction D1 (i.e., the central region Y12) to 1 / 2 (i.e., the combined region of regions Y22 and Y23). This makes it possible to more reliably suppress the occurrence of self-adhesion of the fixing members 11 and 12 even if the absorbent article 1 experiences significant warping or deformation.
[0057] In this embodiment, the fixing members 11 and 12 are adhesive members having adhesive properties (for example, hot melt adhesive). With the above configuration, by using fixing members 11 and 12 that are easily self-adhered due to their adhesive properties, and by adopting a configuration in which the fixing members 11 and 12 are not provided in the central region A1 as described above, it is possible to easily fix the absorbent article 1 to the wearable article 100 while effectively suppressing the occurrence of self-adhesion.
[0058] In this embodiment, the surface 4a of the non-skin side Z2 of the back sheet 4 is made of a film. In this embodiment, the back sheet 4 is made of a film member, and there is no outer sheet such as a nonwoven fabric covering the non-skin side Z2 of the film member. As a result, the surface 4a of the back sheet 4 is a film surface. With the above configuration, when there are fixing members 11 and 12 which are adhesive members, and a release sheet is provided on the surface (adhesive surface) of the fixing members 11 and 12 in the state before use, the fixing members 11 and 12 can be left cleanly on the film surface when the release sheet is peeled off. If the surface 4a of the non-skin side Z2 of the back sheet 4 is made of a fuzzy nonwoven fabric or the like, there is a risk that when the release sheet is peeled off, a part of the fixing members 11 and 12 which are adhesive members may peel off together with the release sheet. With the above configuration, such problems can be avoided, and as a result, stable adhesive performance to the wearable item 100 can be ensured.
[0059] As shown in Figure 2, in this embodiment, the fixing members 11 and 12 have portions that overlap with the absorber 5 in the thickness direction D3. In this embodiment, a portion of the inner side of each fixing member 11 and 12 in the waist circumference direction D1 overlaps with the absorber 5. With the above configuration, the rigidity of the region where the fixing members 11 and 12 are provided is increased by the presence of the absorber 5. As a result, twisting and bending in the region A2 where the fixing members 11 and 12 and the absorber 5 overlap is suppressed, and the self-adhesion of the fixing members 11 and 12 placed in the region A2 can be more effectively suppressed. Furthermore, since the absorber 5 and the fixing members 11 and 12 are fixed together to the wearable item 100 in the region A2, displacement of the absorber 5 can be more effectively suppressed.
[0060] In this embodiment, the width W of each fixing member 11, 12 in the waist direction D1 is 50 mm or less. With the above configuration, it is possible to suppress the area of each fixing member 11, 12 from becoming excessively large and further reduce the risk of self-adhesion when the absorbent article 1 is twisted. In this embodiment, the fixing members 11, 12 have the same shape and width W, but they may have different shapes, widths, etc. Also, if the width of the fixing member in the waist direction D1 changes along the front-to-back direction D2, in order to obtain the above effect, the width of the part of the fixing member with the maximum width (maximum width) should be 50 mm or less. In addition, the width W of each fixing member 11, 12 in the waist direction D1 is preferably 10 mm or more from the viewpoint of ensuring sufficient fixing force to the wearable article 100.
[0061] In this embodiment, at least a portion of the fixing members 11 and 12 (the outer portion in the circumference direction D1) is positioned within 15 mm of the edges 5c and 5d of the absorber 5 in the circumference direction D1. At least a portion of the fixing member 11 is positioned within 15 mm of the edge 5c on the edge E3 side of the absorber 5. In this embodiment, a portion of the inner part of the fixing member 11 in the circumference direction D1 overlaps with a portion of the absorber 5 including the edge 5c. That is, since the fixing member 11 has a portion that overlaps with the edge 5c of the absorber 5, it is positioned within 15 mm of the edge 5c. However, in order to satisfy the above positioning requirement, the fixing member 11 is positioned on the edge E3 side of the main body 2 than the edge 5c of the absorber 5, and the end of the fixing member 11 on the absorber 5 side is positioned within 15 mm of the edge 5c. Similarly, at least a portion of the fixing member 12 is positioned within 15 mm of the edge 5d on the edge E4 side of the absorber 5. In this embodiment, a portion of the inner side of the fixing member 12 in the waist direction D1 overlaps with a portion including the edge 5d of the absorbent 5. That is, since the fixing member 12 has a portion that overlaps with the edge 5d of the absorbent 5, it is positioned within 15 mm of the edge 5d. However, in order to satisfy the above positioning requirement, the fixing member 12 is positioned on the edge E4 side of the main body 2 rather than the edge 5d of the absorbent 5, and the end of the fixing member 12 on the absorbent 5 side is positioned within 15 mm of the edge 5d. With the above configuration, the vicinity of the edge (near the edges 5c and 5d) of the absorbent 5, which is relatively rigid within the absorbent article 1, can be firmly fixed to the wearable article 100. This makes it possible to maintain a stable attachment state of the absorbent article 1 to the wearable article 100. Furthermore, in order to enhance the above effects, it is preferable that at least a portion of the fixing members 11 and 12 overlaps with a portion of the absorber 5 when viewed from the thickness direction D3, and that the portion is included in a region within 15 mm from the edge 5c or 5d of the absorber 5 toward the inside of the absorber 5. This allows for obtaining the effects of the case where the fixing members 11 and 12 and the absorber 5 overlap as described above.
[0062] [Differentiation] Although embodiments of the present disclosure have been described above, the present disclosure is not limited to the embodiments described above. The materials and shapes of each component are not limited to those described above, and various materials and shapes can be used. In addition, some components of the absorbent article 1 described above may be modified or omitted.
[0063] In the above embodiment, the front leak-proof wall portion 20 had a different configuration from the rear leak-proof wall portion 30, but the front leak-proof wall portion 20 may be configured in the same way as the rear leak-proof wall portion 30 described above. Alternatively, the rear leak-proof wall portion 30 may be configured in the same way as the front leak-proof wall portion 20 described above. In other words, the configurations of the leak-proof wall portions 20 and 30 shown in this embodiment are just examples, and the absorbent article 1 may have leak-proof wall portions with configurations different from the front leak-proof wall portion 20 and rear leak-proof wall portion 30 described above.
[0064] In the above embodiment, adhesive members (hot melt adhesives) that are particularly prone to self-adhesion were described as examples of fixing members 11 and 12. However, the effects of this embodiment described above can also be obtained when fixing members other than adhesive members that have self-adhering properties are used. Examples of fixing members other than adhesive members include hook members of mechanical fasteners (hook fasteners) or gel-like members with adhesive properties. However, as described above, the effects of this embodiment are more preferably exhibited when adhesive members that are prone to self-adhesion are used as fixing members 11 and 12.
[0065] Figure 7 is a plan view of the absorbent article 1A according to the first modified example, as seen from the non-skin side Z2. As shown in Figure 7, the absorbent article 1A differs from the absorbent article 1 in that it has a fixing member 11A instead of fixing member 11, and a fixing member 12A instead of fixing member 12.
[0066] The fixing member 11A differs from the fixing member 11 in that it has multiple (three in this example) parts 11a, 11b, and 11c that are spaced apart in the front-rear direction D2. For example, each part 11a, 11b, and 11c is formed in a rectangular shape of the same size. Part 11a is located in the front region X1. Part 11b is located in the front-rear central region X2. Part 11c is located in the rear region X3.
[0067] The fixing member 12A differs from the fixing member 12 in that it has multiple (three in this example) parts 12a, 12b, and 12c that are spaced apart in the front-rear direction D2. For example, each part 12a, 12b, and 12c is formed in a rectangular shape of the same size. Part 12a is located in the front region X1. Part 12b is located in the front-rear central region X2. Part 12c is located in the rear region X3.
[0068] Like the absorbent article 1A, each fixing member 11A, 12A may be composed of multiple parts spaced apart in the front-rear direction D2. With this configuration, compared to the case where fixing members 11, 12 extending in a long length in the front-rear direction D2, as in the absorbent article 1, the flexibility of the absorbent article 1A in the front-rear direction D2 can be increased by the regions between the multiple parts in the front-rear direction D2 (i.e., non-fixed regions where no fixing members exist). In this example, the non-fixed regions are the regions between part 11a and part 11b, between part 11b and part 11c, between part 12a and part 12b, and between part 12b and part 12c. As a result, the absorbent article 1A can flexibly follow the movements of the pet as it curls up and stretches its body. Therefore, the feeling of stiffness and tension when wearing it can be reduced, and the comfortable wearing experience for the pet can be further improved.
[0069] Furthermore, in the absorbent article 1A described above, in order to further enhance the conformability of the absorbent article 1A to the pet's body in the front-to-back direction D2 by securing a larger non-fixed area, for example, parts 11b and 12b provided in the front-to-back central region X2 may be omitted. That is, the fixing member 11A may have only parts 11a and 11c provided in the front region X1 and the rear region X3. Similarly, the fixing member 12A may have only parts 12a and 12c. In this case, by fixing the four corners of the main body 2 to the wearable item 100 with parts 11a, 11c, 12a and 12c, stable fixing of the absorbent article 1A to the wearable item 100 can be ensured, while further enhancing the conformability of the absorbent article 1A by securing a larger non-fixed area (i.e., the area between parts 11a and 11c, and the area between parts 12a and 12c).
[0070] Figure 8 is a plan view of the absorbent article 1B according to the second modified example, viewed from the non-skin side Z2. As shown in Figure 8, the absorbent article 1B differs from the absorbent article 1 in that it has a fixing member 11B instead of fixing member 11, and a fixing member 12B instead of fixing member 12. In addition, the absorbent body 5 of the absorbent article 1B has a larger dimension in the waist direction D1 than the absorbent body 5 of the absorbent article 1. The fixing member 11B differs from the fixing member 11 in that its entirety overlaps with the absorbent body 5. The fixing member 12B differs from the fixing member 12 in that its entirety overlaps with the absorbent body 5. In the example in Figure 8, the fixing member 11B overlaps with the end of the absorbent body 5 on the edge E3 side, and the fixing member 12B overlaps with the end of the absorbent body 5 on the edge E4 side. Thus, the fixing members 11B and 12B may be arranged so that they overlap the absorbent body 5 overall. In this case, the rigidity of the entire region where the fixing members 11B and 12B are provided is increased by the presence of the absorber 5. As a result, twisting and bending are suppressed throughout the entire region where the fixing members 11B and 12B are placed, and the self-adhesion of the fixing members 11B and 12B can be suppressed even more effectively. In addition, since the absorber 5 and the fixing members 11B and 12B are fixed together to the wearable item 100, displacement of the absorber 5 can be suppressed even more effectively.
