Detailed Description
Hereinafter, an absorbent article according to an embodiment of the present invention will be described with reference to the drawings. The configurations of the following embodiments are merely examples, and the present invention is not limited to the configurations of these embodiments.
< embodiment >
In the present embodiment, a tape-type disposable diaper (which is an example of an "absorbent article" referred to in the present application and will be hereinafter simply referred to as "diaper") is configured such that a direction connecting a front body disposed to face an abdomen of a user and a rear body disposed to face a back of the user is defined as a longitudinal direction. The crotch portion disposed in the crotch (disposed opposite to the crotch) of the user is located between the front body (one side in the longitudinal direction) and the rear body (the other side in the longitudinal direction) (the center in the longitudinal direction). In a state where the diaper is worn by a user (hereinafter, simply referred to as a "worn state"), a side facing the skin of the user (an inner side in the worn state) is referred to as a skin surface side, and an opposite side to the skin surface side (an outer side in the worn state) is referred to as a non-skin surface side. The direction connecting the skin surface side and the non-skin surface side is defined as the thickness direction, and the direction perpendicular to both the longitudinal direction and the thickness direction is defined as the width direction. In addition, the thickness direction is regarded as a planar view.
Fig. 1 is a perspective view of a diaper of the present embodiment. The diaper 1 has a crotch region 1B corresponding to a crotch region covering the pudendal region of the user in a worn state, a front body region 1F corresponding to a front body of the user and located on the front side of the crotch region 1B, and a rear body region 1R corresponding to a rear body of the user and located on the rear side of the crotch region 1B.
When the tapes 2L and 2R are attached to the front patch 2F in a state where the front body region 1F is disposed on the abdominal side of the user and the rear body region 1R is disposed on the back side of the user, the diaper 1 is fixed to the body of the user in a state of surrounding the abdominal circumference and the thighs of the user. Since the diaper 1 is fixed to the body of the user in this manner, the user can walk while standing while wearing the diaper 1.
In the diaper 1, a liquid-absorbable absorbent body capable of absorbing and retaining liquid is disposed mainly centered around the crotch region 1B. In addition, in the diaper 1, in order to suppress the formation of a gap which becomes an outflow path of liquid between the diaper 1 and the skin of the user, the three-dimensional gathers 3BL, 3BR are provided at a portion surrounding the thighs of the user, and the waist gather 3R is provided at a portion surrounding the abdominal circumference of the user. The three-dimensional gathers 3BL, 3BR and the waist gather 3R are brought into close contact with the skin of the user by the elastic force of the linear rubber. Thus, the liquid discharged from the pudendal region of the user hardly leaks from the diaper 1 and is absorbed by the absorbent body of the diaper 1.
The top sheet is disposed on the skin surface side of the absorbent body. The top sheet is made of a nonwoven fabric having good water permeability and good skin touch. The top sheet prevents the absorbent body from being displaced, and also prevents the liquid discharged from the pudendum of the user from rapidly permeating from the skin surface side to the absorbent body to keep the skin surface of the user in a dry state, and prevents the liquid from flowing back from the absorbent body to the skin surface. A back sheet is disposed between the absorbent body and the cover sheet 4. The back sheet is, for example, a water-impermeable film sheet to prevent liquid that has flowed into the absorbent body from leaking out of the cover sheet 4. The backsheet may also have waterproof moisture vapor permeability. If the back sheet has moisture permeability, part of the moisture contained in the liquid that has flowed into the absorbent body can be released to the back sheet side, and therefore the user's comfort can be maintained for a long time.
It is conceivable to use a short fiber material for the material of the cover sheet 4. In such a case, if the front patch 2F is transparent or translucent or the front patch 2F is of the same color as the cover sheet 4, the tapes 2L and 2R may be attached so as to protrude (protrude) from the front patch 2F. In this case, the short fibers are entangled with the hook materials of the belts 2L and 2R. This makes it difficult to repeatedly attach the tapes 2L and 2R to the diaper 1.
In the present embodiment, a technique is provided for suppressing the tapes 2L and 2R from sticking to the cover sheet 4 so as to protrude from the front patch 2F when the cover sheet 4 contains a short fiber material.
Fig. 2 is an example of a partially enlarged view of the vicinity of the front patch 2F when viewed from the non-skin side. As shown in fig. 2, the front patch 2F is disposed so as to lie down in the width direction of the patch 4. The front patch 2F is rectangular in shape, and its color is white. The front patch 2F is a nonwoven fabric made of fibers having a fiber length of 50mm or more. Further, for example, red (an example of "predetermined color" in the present disclosure) is given to the entire circumference of the edge 5 of the front patch 2F. The width of the red-colored edge 5 is, for example, 5mm or more. In fig. 2, the application pattern is changed according to the color in order to express the color difference.
The cover sheet 4 provided with such a front patch sheet 2F forms the exterior surface of the diaper 1. The cover sheet 4 is made of a nonwoven fabric made of short fibers (for example, fibers having a length of less than 50 mm) in order to improve the texture of the diaper 1. The cover sheet 4 may be made of a nonwoven fabric made of a liquid-impermeable thermoplastic resin, for example, in order to prevent leakage of excrement. Examples of the liquid impermeable thermoplastic resin include Polyethylene (PE), polypropylene (PP), and the like. The cover sheet 4 is not limited to a single-layer structure, and may have a multilayer structure including an inner cover sheet and an outer cover sheet. The cover sheet 4 is white in the same manner as the front patch 2F.
As shown in fig. 2, a mark 21 (an example of the "medium" in the present disclosure) that can be targeted when the tapes 2L and 2R are attached is provided on the front patch 2F. The mark 21 is of a different colour, for example blue, to the edge 5. Alignment marks (english: register marks) 22 (an example of "mark" in the present disclosure) are provided on both ends of the cover sheet 4 in the width direction. The alignment marks 22 are used for positioning when various sheets are attached to the diaper 1 during the manufacture of the diaper 1. The color of the alignment mark 22 is red as in the color of the edge 5.
Fig. 3 is an example of a partially enlarged view of the vicinity of the belt 2L. As shown in fig. 3, the belt 2L has a portion extending in a rectangular shape in the width direction from one end portion in the width direction of the rear body of the diaper 1. Further, the rectangular portion has a tip portion 25 extending in the width direction. Further, a hook portion 23 having a width of, for example, 24mm is provided on the skin surface side of the distal end portion 25. The length of the hook 23 on the right side in fig. 3 is, for example, 27mm, and the length on the left side is, for example, 31mm. Note that, although the belt 2L is illustrated in fig. 3, the belt 2R has the same structure as the belt 2L.
Fig. 4A and 4B show an outline of the case where the tapes 2L and 2R are attached to the front patch 2F. Fig. 4A is an example of a cross-sectional view of the front patch 2F. Fig. 4B is a schematic view of the front patch 2F viewed from the non-skin side.
As shown in fig. 4A, in the hook portion 23, a hook 72 is provided so as to protrude toward the skin surface side. The hook 72 includes a columnar projection 72a and an extension 72b extending from an end of the projection 72a in the projection direction in a direction orthogonal to the projection direction. The cross-sectional shape of the extending portion 72b in the direction orthogonal to the projecting direction is a substantially elliptical shape. The size of the cross-sectional area of the extension portion 72b increases as it advances in the protruding direction of the projection portion 72 a. That is, the length of extension 72b extending in the direction orthogonal to the projecting direction of projection 72a increases as one goes toward the projecting direction.
Such a hook 72 is 2.7 × 10 6 Per m 2 The left and right densities are provided on the surface of the hook portion 23. The radius of the convex portion 72a is about 105 μm. The length of extension 72b at the end of projection 72a in the projection direction is about 95 μm with respect to projection 72 a. The diameter of the fibers 24 of the nonwoven fabric forming the front patch 2F to which the hooks 72 are attached is, for example, about 12 μm, and the basis weight of the nonwoven fabric is, for example, about 15 g/m.
When the hook portion 23 is pressed against the front patch 2F, the extending portion 72b is pressed in the direction of the hook portion 23 by the fibers 24 of the nonwoven fabric forming the front patch 2F. Thereby, the extending portion 72b is elastically deformed with the integrally formed convex portion 72a as a fixed end. And, the fibers 24 enter the gaps between the projections 72 a. After that, the elastically deformed extension portion 72b is restored to the original shape, and thereby the fiber 24 is held between the extension portion 72b and the hook portion 23 as shown in fig. 4A. After that, even if the user stops pressing of the belt 2L, the fiber 24 is held between the extension 72b and the hook 23. By this mechanism, the bands 2L and 2R are fixed to the front patch 2F (see fig. 4B). That is, the front patch 2F functions as a surface fastener that can attach the tapes 2L and 2R.
In addition, in a state where the fibers 24 are held between the extended portions 72b and the hook portions 23, when a force is applied in a direction to peel the tapes 2L, 2R from the front patch 2F, the extended portions 72b elastically deform, and the fibers 24 are loosened from between the extended portions 72b and the hook portions 23. The fiber 24 is a long fiber having a fiber length of 50mm or more. This can prevent the fibers 24 from being entangled with the hooks 72 of the hook portion 23. This enables the peeled tapes 2L and 2R to be attached to the front patch 2F again.
According to the front patch 2F as described above, the entire circumference of the edge 5 is given red color. Thereby, the tapes 2L, 2R can be guided to be attached to the portion surrounded by the edge 5. However, it is also conceivable to attach the front patch 2F in a state where a part of the hook portion 23 of the tapes 2L, 2R is projected outside the edge 5. As a result, the short fibers of the cover sheet 4 are entangled with the hook portions 23 of the projecting portions, and the projecting portions do not function as surface fastener, and as a result, the fixing strength is expected to decrease when the tapes 2L, 2R are repeatedly attached to the front patch 2F. Then, the force with which the tapes 2L and 2R attached to the outside of the edge 5 with the hook portions 23 extending therefrom were peeled from the front patch 2F was measured as follows. Further, it was confirmed that there is no problem in fixing the diaper 1 to the user as long as the hook portions 23 of the tapes 2L, 2R and the front patch 2F overlap to some extent.
[ peeling test ]
Fig. 5A, 5B, and 5C illustrate a state in which the tape 2R (hereinafter referred to as member a) separated from the diaper 1 is attached to the front patch 2F. Fig. 5A illustrates a case where the entire area of the hook 23 is attached to the front patch 2F. On the other hand, fig. 5B and 5C illustrate a mode of being attached to the front patch 2F in a state where a part of the hook portion 23 is extended from the front patch 2F. Fig. 5B illustrates a case where the overlapping area of the hook portion 23 and the front patch 2F is about 67% with respect to the area of the hook portion 23. Fig. 5C illustrates a case where the overlapping area of the hook portion 23 and the front patch 2F is about 33% with respect to the area of the hook portion 23. Furthermore, the overlap area of FIG. 5A is about 7.0cm 2 The overlap area of FIG. 5B is about 4.6cm 2 The overlap area of FIG. 5C is about 2.3cm 2 。
In the peel test, first, as shown in fig. 5A to 5C, the member a is extended from the front patch 2F in a stepwise manner. Then, in each state of fig. 5A to 5C, the rear end portion of the member a is gripped by a predetermined grip portion from a direction perpendicular to the front patch 2F, and pulled at a predetermined speed (for example, 300 mm/min). Then, the tensile force acting on the predetermined grip portion is measured until the member a is peeled off from the front patch 2F. Such a test was repeated 4 times for each of the states of fig. 5A to 5C.
Fig. 6 shows an example of the test result of the maximum value of the tensile force measured in the peeling test. As shown in fig. 6, it can be seen that: in the state of fig. 5A to 5C, a force of about 0.6N or more is required to peel off the member a. Incidentally, the force of 0.6N corresponds to a force at which the member a is not peeled off from the front patch 2F even when the diaper 1 is worn by a crawling child 12 hours in the day or 12 hours in the night. Thus, it was confirmed that: if the overlapping area of the hook portion 23 and the front patch 2F is about 33% or more with respect to the area of the hook portion 23 (for example, if there is an overlapping area of the state of fig. 5C or more), there is no problem in the wearability of the diaper 1 to the user.
[ Effect, effect ]
In the case where the red color is not given to the edge 5 of the front patch 2F, since the colors of the front patch 2F and the cover sheet 4 are the same white color, the user may stick the hook portions 23 of the tapes 2L, 2R so as to protrude from the front patch 2F. However, according to the diaper 1 described above, the user can visually confirm the boundary between the front patch 2F and the cover sheet 4 by the difference in color between the front patch 2F and the edge 5. This can prevent the user from sticking the hook portions 23 of the tapes 2L, 2R to the outside of the edge 5 of the front patch 2F. This can prevent the short fibers of the cover sheet 4 from being entangled with the hook portions 23 of the tapes 2L and 2R. This enables the tapes 2L and 2R to be repeatedly attached to the front patch 2F. Further, the cover sheet 4 is prevented from being fluffed due to the hook portions 23 of the tapes 2L and 2R being stuck to the cover sheet 4. Further, the opening of the cover sheet 4 due to the hook portion 23 being peeled off from the cover sheet 4 can be suppressed. This enables the user to wear the same diaper 1 for a long time. Thereby being economical for the consumer.
In addition, according to the diaper 1 described above, even when the user attaches the tapes 2L and 2R to the outside of the edge 5 of the front patch 2F, if the overlapping area of the hook portion 23 and the front patch 2F is about 33% or more of the area of the hook portion 23, the user can wear the diaper about 1 day and live (see fig. 5A, 5B, 5C, and 6).
Further, according to the results of the peel test shown in fig. 5A, 5B, 5C, and 6, when the width of the edge 5 is set to be 33% or more of the length of the hook portion 23 of the tapes 2L, 2R in the longitudinal direction (vertical direction in fig. 5A, 5B, and 5C), if the end portion in the longitudinal direction of the hook portion 23 is attached along the inner edge of the edge 5 as shown in fig. 5C as the attaching method of the hook portion 23, the overlapping area between the hook portion 23 and the front patch 2F is automatically secured to be 33% or more. Thus, the user can live with the diaper worn for about 1 day. When the short fibers of the cover sheet 4 are entangled with the hooks 72 of the hook portions 23 protruding from the front patch 2F, if the tapes 2L and 2R are peeled off from the front patch 2F and the entire area of the hook portions 23 is attached to the front patch 2F again, the overlapping area between the hook portions 23 and the front patch 2F becomes about 33%. Even in such a case, the user can live about 1 day wearing the diaper. Such a diaper 1 can be said to be a highly serviceable diaper. The width of the edge 5 may be 33% or more of the width-directional dimension of the hook 23.
In addition, according to the diaper 1 as described above, the color of the edge 5 of the front patch 2F is different from the color of the mark 21 marked on the front patch 2F. This also enables the edge 5 to function as an alignment mark. This makes the positioning when the various sheets are attached to the diaper 1 more reliable in the manufacture of the diaper 1.
In addition, according to the diaper 1 as described above, the color of the margin 5 is different from the color of the mark 21 but the same as the color of the alignment mark 22. Thus, the user viewing the diaper 1 recognizes that the edge 5 is different from the display such as the mark 21 displayed on the diaper 1. This makes the edge 5 impressive to the user, and therefore, the user can be inhibited from attaching the hook portions 23 of the tapes 2L, 2R to the outside of the edge 5.
In addition, according to the diaper 1 described above, the width of the edge 5 is 5mm or more. This makes the front patch 2F conspicuous by the edge 5. This also prevents the user from sticking the hook portions 23 of the tapes 2L and 2R to the outside of the edge 5. As described above, in the present embodiment, when the cover sheet 4 contains a short fiber material, the tapes 2L and 2R can be prevented from sticking to the cover sheet 4 so as to protrude from the front patch 2F.
[ 1 st modification ]
Fig. 7 is an example of a partially enlarged view of the vicinity of the front patch 2F of the diaper 1A according to the first modification 1. As shown in fig. 7, in the diaper 1A of modification 1, four corners of the edge 5 of the front patch 2F are colored red. Note that red may be given to a part of the edge 5 of the front patch 2F, instead of the four corners of the edge 5. The absorbent body 6 disposed on the skin surface side of the cover sheet 4 of the diaper 1A is disposed so that its longitudinal end overlaps a part of the inner edge of the edge 5. The arrangement of the absorber 6 is not limited to the state shown in fig. 7, and may be overlapped with at least a part of the edge 5.
[ Effect, effect ]
According to the diaper 1A as described above, a difference in thickness is produced at the edge 5. Thus, the user can recognize the difference in thickness by pressing the edge 5 with a finger, in addition to the fact that the user can visually recognize the boundary between the front patch 2F and the cover sheet 4 by the difference in color between the edge 5 and the cover sheet 4. This allows the user to recognize the boundary between the front patch 2F and the cover sheet 4. Thus, even when the entire edge 5 is not colored, but a part thereof is colored as shown in fig. 7, the user can easily recognize the boundary between the front patch 2F and the cover sheet 4. This can prevent the user from sticking the hook portions 23 of the tapes 2L and 2R to the outside of the edge 5 of the front patch 2F.
[ modification 2 ]
Next, a2 nd modification will be described. An infant, which is an example of a user of the diaper 1, has a body that is very small compared to an adult. Therefore, the abdominal circumference of the user is likely to change due to lactation or the like. When the user wears the diaper 1 firmly against the abdominal circumference of the user in the fasting state and performs nursing, the abdominal circumference of the user is greatly expanded, fastening of the diaper 1 becomes extremely strong, and there is a problem that the user may spit milk or the like without holding the fastening of the diaper 1. The purpose of modification 2 is to provide a diaper that can flexibly cope with changes in the abdominal circumference of a user.
Fig. 8 is an example of a partially enlarged view of the vicinity of the front patch 2F of the diaper 1A2 of the 2 nd modification. As shown in fig. 8, in the diaper 1A2 of the 2 nd modification, the longitudinal end portions of the absorbent body 6 extend inside the portion surrounded by the edge 5 of the front patch 2F.
Fig. 9 is a sectional view of a front body region of a diaper 1A2 provided with a front patch 2F of modification 2. Fig. 9 is a cross-sectional view of the diaper 1A2 cut along the longitudinal direction. In modification 2, a top sheet 7 as a skin-side sheet is disposed on the skin surface side of the diaper 1A2, and the absorber 6 extends over a fixed range on the non-skin surface side of the top sheet 7. A water-impermeable back sheet 8 is disposed between the absorbent body 6 and the cover sheet 4, and the cover sheet 4 is further disposed on the non-skin surface side thereof. A front patch 2F as an attachment portion is provided in a certain range on the non-skin surface side of the cover sheet 4. The absorbent body 6 and each sheet shown in fig. 9 are joined to the adjacent absorbent body 6 or other sheet by an adhesive such as a hot melt.
In the modification 2, the top sheet 7, the back sheet 8, and the cover sheet 4 extend longer than the absorbent body 6 in the longitudinal direction connecting the front body and the back body. In fig. 9, the topsheet 7, the backsheet 8, and the cover sheet 4 extend to the longitudinal ends of the diaper 1 A2. The top sheet 7, the back sheet 8, and the cover sheet 4 are joined to each other at the longitudinal end sides of the longitudinal ends of the absorbent body 6 without interposing the absorbent body 6 therebetween.
In addition, the top sheet 7 in the modification 2 has a flat skin contact surface, and the back sheet 8 and the cover sheet 4 of the diaper 1 bulge toward the non-skin surface side in the extension region of the absorbent body 6 under the influence of the thickness of the absorbent body 6. On the other hand, in the region where the absorbent body 6 does not extend, the back sheet 8 and the cover sheet 4 of the diaper 1 are disposed close to the skin surface side because they are joined to the top sheet 7. Therefore, the back sheet 8 and the cover sheet 4 are bent toward the skin surface side at the longitudinal end portion side of the longitudinal end portion of the absorbent body 6, and a step 9 is formed at this portion.
A front patch 2F as an attachment portion is joined and arranged on the non-skin surface side of the cover sheet 4. The front patch 2F is disposed so that its disposition region overlaps the step 9, and the step 9 is formed at least on the longitudinal inner side of the longitudinal end of the front patch 2F. It is more preferable that the longitudinal end of the absorbent body 6 is provided in an area inside the edge 5 of the front patch 2F, that is, in an area surrounded by the edge 5. In this way, the step 9 is provided inside the edge 5 to which a red color is given as an example, at the longitudinal end portion side of the front patch 2F.
[ Effect, effect ]
According to the diaper 1A2 described above, in the crotch region 1A2 side of the front patch 2F, that is, in the extension region of the absorbent body 6, the diaper 1A2 bulges toward the non-skin surface side due to the thickness of the absorbent body 6, and the front patch 2F also bulges toward the non-skin surface side. When the guardian or the like engages the inner side of the edge 5 of the front patch 2F with the tapes 2L and 2R in order to put the diaper 1A2 on the user, the portions of the tapes 2L and 2R protruding toward the non-skin surface side of the front patch 2F can be easily and firmly engaged. On the other hand, a step 9 generated by the absence of the thickness of the absorbent body 6 is present in the front patch 2F at a portion corresponding to the longitudinal end of the absorbent body 6, and the step 9 is in a state of being one step lower toward the non-skin surface side on the longitudinal end side. That is, a step 9 is formed at a specific portion of the extension region of the front patch 2F of the diaper 1A2 by the longitudinal end of the absorbent body 6. When a guardian or the like engages the front patch 2F with the tapes 2L, 2R so as to straddle the step 9, the tapes 2L, 2R can be firmly engaged with each other on the side of the longitudinal crotch region 1B of the step 9, i.e., on the side where the thickness of the absorber 6 is present, but the longitudinal end of the step 9 is recessed toward the skin surface, making it difficult to firmly engage with each other.
Therefore, when the abdominal circumference of the user is greatly expanded by nursing or the like, the engagement of the longitudinal direction end portions of the bands 2L and 2R attached to the front patch 2F is easily released. When the engagement of the longitudinal end portions of the belts 2L and 2R is released, the fastening force of the diaper 1A2 to the abdominal circumference of the user decreases. Therefore, the user is less likely to cause spitting. Even when the abdominal circumference is expanded and the engagement between a part of the bands 2L and 2R and the front patch 2F is once released, the entire bands 2L and 2R are re-engaged with the front patch 2F after a while. In particular, when the diaper is used in a state where the garment covering pressure of the garment is applied, the tapes 2L and 2R are very easily re-engaged by the garment covering pressure. In this way, in the diaper 1A2 of modification 2, the step 9 caused by the end of the absorbent body 6 is provided inside the edge 5 of the front patch 2F, so that the diaper can easily follow the temporary expansion of the abdominal circumference of the user, and can prevent the discharge or the like caused by the temporary excess tightening.
Further, the step 9 is preferably formed inside the edge 5 of the front patch 2F. By forming the step 9 inside the edge 5, even if the guardian or the like engages the belts 2L and 2R with the front patch 2F so as to straddle the step 9, the hook portions 23 of the belts 2L and 2R are not easily engaged with the cover piece 4, and thus the engagement force of the belts 2L and 2R can be prevented from being reduced.
[ modification 3 ]
Next, a modification 3 will be described. Fig. 10A and 10B are diagrams illustrating a mode in which the tapes 2L and 2R of the 3 rd modification are attached to the front patch 2F. In the diaper 1, since the color is given to the edge 5 of the front patch 2F, when the guardian or the like wears the diaper 1 on the user, the tapes 2L and 2R are easily attached to the inside of the edge 5 accurately. Fig. 10A is a view showing a state where the hook portion 23 of the tape 2R is appropriately fitted to the inside of the edge 5 of the front patch 2F. However, the user, the guardian, or the like cannot be completely prevented from coming into contact with the front patch 2F and engaging with the cover sheet 4 so that a part of the straps 2L and 2R passes over the edge 5 and is detached from the front patch 2F. The cover sheet 4 has a weak engaging force because the surface fibers are more likely to peel off than when the tapes 2L and 2R are bonded to the front patch 2F. In addition, in a state where the surface fibers peeled from the cover sheet 4 are entangled in the hook portions 23, it is difficult to obtain a sufficient engagement force when the surface fibers are attached to the front patch 2F again.
It is conceivable that the tapes 2L and 2R are made translucent, and the color given to the edge 5 is made to transmit through the tapes 2L and 2R, so that the color of the edge 5 appearing on the surface of the tapes 2L and 2R can be visually confirmed, and accurate adhesion can be promoted. Here, when the edge 5 cannot be clearly visually confirmed from the surface of the tapes 2L and 2R, even if the tapes 2L and 2R are attached to the front patch 2F so as to be deviated from the extending region thereof and partially straddle the edge 5, the user, the guardian, and the like may not notice that the tapes 2L and 2R are not properly attached to the front patch 2F. In view of the above, the object of the 3 rd modification is to provide a diaper which can be easily recognized by a user or a guardian when the tapes 2L and 2R are not properly attached to the inner side of the edge 5 of the front patch 2F.
The diaper 1A3 of modification 3 is configured such that the tapes 2L, 2R are translucent and the color of the edge 5 of the front patch 2F is imparted to the complementary color of the colors of the tapes 2L, 2R or a color in a relationship close to the complementary color. Complementary colors are chromatic color combinations that can be mixed to produce achromatic colors, and are color combinations having a relationship of being located at opposite positions in the hue circle. Examples of the combination of colors which are complementary colors include light blue and orange, red and green, and yellow and violet. Since the color of the edge 5 in the above embodiment is red, if green is used as the color of the bands 2L and 2R, the color of the edge 5 and the colors of the bands 2L and 2R can be in a complementary relationship. The color of the edge 5 and the colors of the bands 2L and 2R are not necessarily limited to complementary colors, and may be colors having a relationship close to complementary colors, for example, such that the colors of the bands 2L and 2R are light blue and the color of the edge 5 is yellow. Fig. 10B is a diagram showing a state in which the tape 2R is attached so as to straddle the edge 5 of the front patch 2F. In this figure, the color imparted to the edge 5 of the front patch 2F is transmitted through the translucent band 2R, and clearly appears on the surface of the band 2R in a form that is easily visually recognized by a guardian or the like. Therefore, the user, the guardian, or the like can easily visually confirm that the attachment position of the forward patch 2F of the tapes 2L, 2R is incorrect.
[ Effect, effect ]
If colors in a complementary color relationship are used, the colors of each other are mutually offset, and a psychological effect called complementary color contrast is produced that makes the colors look stronger. Since the color of the edge 5 in the main embodiment is red, when green is used as the color of the bands 2L and 2R, the color of the edge 5 which is seen through from the translucent bands 2L and 2R clearly appears by the complementary color effect when the bands 2L and 2R are stuck so as to protrude from the edge 5. Therefore, the user or the guardian can more easily judge that the tapes 2L, 2R are attached to the edge 5 by being hung. Further, since the complementary color contrast brings about a very strong psychological effect, the colors of the bands 2L, 2R and the edge 5 may be a combination of colors close to the complementary colors such as yellow and light blue but slightly deviated from the complementary color relationship, so that a combination of a close complementary color contrast effect and a reduction in psychological irritation to the user and the guardian can be obtained.
[ 4 th modification ]
Fig. 11 is an example of a partially enlarged view of the front patch 2FB included in the diaper 1A4 of the 4 th modification. As shown in fig. 11, two front patches 2FB are arranged in line in the width direction. In fig. 11, the tape 2R is attached to the left front patch 2FB, and the tape 2L is attached to the right front patch 2 FB. In addition, the entire circumference of each edge 5 of the front patch 2FB is marked with red. The diaper 1A4 of the 4 th modification can also provide the same effects as those of the embodiment. That is, two application portions may be provided in the width direction, and a predetermined color different from the color of the sheet-like member may be given to at least a part of each edge of the application portions.
[ other modifications ]
The front region 1F of the diaper 1 may be provided with the tapes 2L and 2R, and the rear region 1R may be provided with the front patch 2F on the outer surface thereof. The diaper 1 of the above embodiment is a so-called belt-type diaper, but may be an underpants-type diaper. The diaper 1 may be provided with the belts 2L and 2R and the front patch 2F so as to fasten the waist portion of the pants-type diaper. The colors of the front patch 2F, the cover sheet 4, and the edge 5 of the front patch 2F are not limited to the above colors. The color of the front patch sheet may be transparent, translucent or the same color as that of the cover sheet 4. The color given to the edge may be different from that of the cover sheet 4. The mark 21 and the alignment mark 22 may not be provided. The color of the edge 5 may be different from that of the mark 21. The color of the edge 5 may be the same as that of the alignment mark 22. In addition, the width of the edge 5 may also be less than 5mm.
The embodiment and the modification in the present disclosure can appropriately attach the band-shaped member.
The embodiments and the modifications disclosed above can be combined separately.
