Description

  The present invention relates to a disposable diaper of a type that is attached by fastening a fastening tape to a target tape.

  For disposable diapers of the type that are attached by fastening the left and right fastening tapes provided on the back side of the diaper to the target tape provided on the outer surface of the abdomen, that is, so-called tape type diapers If the left and right balance is lost when the tape is fastened, liquid leakage tends to occur easily. Therefore, for the purpose of balancing the fastening positions of the left and right fastening tapes, for example, a technique for applying a scale or the like as a guide to the fastening position on the target tape by means of printing or the like and visually recognizing the fastening position. Various proposals have been made.

  However, simply providing a means for visually recognizing the stop position causes inconveniences when the diaper is changed in a dark place such as at night or when a person with visual impairment changes the diaper. For the purpose of eliminating such inconvenience, in Patent Document 1, in a disposable diaper provided with a fastening tape made of an adhesive tape, the surface of the target tape is identified as a convex or concave shape in an area where the adhesive tape is not bonded. It has been proposed to provide a mark.

Japanese Patent Laid-Open No. 9-38128

  In the diaper described in Patent Document 1, the identification mark is provided only at the center in the width direction of the target tape. Therefore, the center portion of the target tape can be recognized by the identification mark without sight. However, when it is desired to change the fastening position of the fastening tape according to the waist size of the wearer, the identification mark is not provided at a position left and right away from the center, so that such a position is not visually recognized. It is not easy to fasten the fastening tape symmetrically.

  Therefore, the subject of this invention is providing the disposable diaper of the tape stop type which can eliminate the fault which the prior art mentioned above has.

The present invention has a crotch part located in the crotch of the wearer in the wearing state, and an abdominal side part and a back side part extending from the front and back of the crotch part, and is fastened to the left and right side areas of the back side part. In a disposable diaper provided with a fastening tape, and provided with a target tape to which the fastening tape is fastened to the outer surface of the abdomen,
The target tape is provided with a center index at a position that bisects the target tape to the left and right, and is further biased toward the upper end side and / or the lower end side of the target tape at a position that is symmetrical with respect to the center index. With two or more sets of fastening indicators,
Both the center index and the fixation index are formed so as to be perceived by tactile sense, and each set of the fixation indices is formed so as to exhibit different tactile sensations, and the fixation index and the center The index also provides a disposable diaper formed so as to exhibit different tactile sensations.

  According to the disposable diaper of the present invention, by touching the target tape, the position at which the fastening tape is fixed symmetrically can be easily recognized. Therefore, since the fastening tape can be fixed symmetrically regardless of vision, diapers in a dark place and diapers of persons with visual impairment can be easily replaced.

The present invention will be described below based on preferred embodiments with reference to the drawings.
The disposable diaper 1 according to the first embodiment shown in FIG. 1 has a crotch part C positioned in the crotch of the wearer in the mounted state, and abdominal side part A and back side part B extending from the front and back of the crotch part C. ing. A pair of fastening tapes 40, 40 are attached to the left and right side regions 20, 20 of the back side B. A target tape 50 to which the fastening tapes 40, 40 are fixed is attached to the outer surface of the ventral portion A.

  The diaper 1 has a liquid-permeable top sheet (not shown), a liquid-permeable or liquid-impermeable back sheet 10, and a liquid-retaining absorbent (not shown) interposed between the two sheets. doing. The diaper 1 has a long shape in which the direction indicated by the symbol X in FIG. 1 is the longitudinal direction and the direction indicated by the symbol Y is the width direction.

  As the top sheet, the back sheet 10 and the absorber, the same ones conventionally used for this type of diaper can be used. As the surface sheet, for example, a liquid-permeable sheet material such as a nonwoven fabric or a perforated film can be used. As the back sheet 10, a water-repellent sheet material such as a synthetic resin film or the like, or a spunbond-meltblown-spunbond nonwoven fabric (SMS nonwoven fabric) can be used. A synthetic resin film may be composed of a microporous film to impart water vapor permeability. Moreover, you may use the composite sheet which laminated | stacked breathable sheets, such as a nonwoven fabric, on the outer surface of a microporous film as a back surface sheet. As the absorbent body, a laminated body of a liquid-retaining fiber material or a laminated body of a mixture of the fiber material and a superabsorbent polymer can be used. The fiber stack may be entirely wrapped with a liquid-permeable sheet such as tissue paper.

  As shown in FIG. 1, the pair of fastening tapes 40, 40 are provided so as to extend outward in the width direction Y of the diaper 1 from the left and right side regions 20, 20 in the back side B of the diaper 1. It has been. The fastening tape 40 includes a base sheet 41 and a fastening portion 42 provided on a surface of the base sheet 41 that faces the same side as the top sheet. As the fastening part 42, the thing similar to what was conventionally used for this kind of diaper can be used. For example, a hook member of a hook-and-loop fastener or an adhesive can be used.

  As shown in FIG. 1, the target tape 50 to which the fastening portions 42 of the fastening tapes 40, 40 are fastened is provided in the central region in the width direction Y on the outer surface of the ventral side A. The target tape 50 has a substantially rectangular shape that is horizontally long in the width direction Y of the diaper 1. The target tape 50 is selected from an appropriate material according to the material of the fastening portion 42 in the above-described fastening tape 40. When the fastening portion 42 is, for example, a hook member of a hook-and-loop fastener, a fiber sheet that can be engaged with the hook member, such as a knitted fabric or a nonwoven fabric, is used as the target tape 50. When the fastening portion 42 of the fastening tape 40 is made of an adhesive, a smooth film made of a synthetic resin can be used as the target tape 50.

  The disposable diaper of this invention has one of the characteristics in the shape of a target tape. Specifically, a center index and a fixing index are provided on the target tape. The center index is an index indicating a position at which the target tape is divided into two equal parts to the left and right. The fixation index is an index indicating a position where the fastening tape is attached to the target tape. Therefore, the center index is formed at a position where the target tape is divided into two equal parts. On the other hand, the fixation index is provided at a position symmetrical with respect to the center index. Two or more sets of anchoring indicators are provided. Furthermore, the fixation index is provided biased toward the upper end side and / or the lower end side of the target tape.

  Specifically, in the embodiment shown in FIG. 2, one center index 51 is provided on the target tape 50 at a position that bisects the entire length in the width direction Y of the target tape 50. The center index 51 extends in the longitudinal direction X in a plan view of the target tape 50 and is formed in a straight line over the entire area in the longitudinal direction X of the target tape 50. Further, the target tape 50 includes three sets of first set fixing indexes 52 and 52, second set fixing indexes 53 and 53, and third set fixing indexes 54 and 54 in order from the center index 51. Each of the fixed indicators is provided. The fixing index of each set is provided at a position that is symmetrical with respect to the central index 51 on the target tape 50. The fixing indexes 52 to 54 have a substantially rectangular shape surrounded by two sides in the width direction Y and two sides in the longitudinal direction X in the plan view of the target tape 50. That is, the fixation indexes 52 to 54 include the upper end edge of the target tape 50. A pair of anchoring indicators constituting each set has a line-symmetric shape with respect to the center indicator 51.

  Both the center index 51 and the fixation index are formed so as to be perceived by touch. Each set of fixation indicators is formed to have a different tactile sensation. Furthermore, the center index and the fastening index are also formed to have different intervals.

  When the diaper 1 of this embodiment is worn, the target index 50 is touched with the fingers of both hands and the center index 51 is searched in a state where the abdomen A is applied to the wearer's abdomen. Since the tactile sensation is different between the center index 51 and the fastening indices 52 to 54, it is easy to find the center index 51. Next, when the fingers of each hand are in contact with the target tape 50, the fingers are moved to the left and right from the center index 51, so that the sticking indices 52, 52, the sticking indices are in order from the center index 51. 53, 53 and the fixing indicators 54, 54 are found. Since the fastening index of each group is formed so as to exhibit different tactile sensations, it is easy to find the fastening index for each group. In this case, since the fixing indexes 52 to 54 are provided to be biased toward the upper end side of the target tape 50, the fixing indexes 52 to 54 are traced by tracing a finger along the upper end portion of the target tape 50. It is easier to perceive the position of. In this way, it is possible to perceive a position symmetrical with respect to the center index 51. Accordingly, the fastening tapes 40 and 40 can be easily fixed at symmetrical positions from the central index 51 using the position of the fixing index of each group as a guide. Thus, according to the present invention, it is possible to easily exchange diapers in a dark place or diapers of persons with visual impairment.

  In particular, in the diaper 1 of the present embodiment, the formation location of the fastening indicators 52 to 54 is biased toward the upper end side of the target tape 50, so that the fastening region of the fastening tape 40 is sufficiently provided on the lower end side of the target tape 50. Can be secured. Therefore, this embodiment has an advantage that a decrease in the engagement force between the target tape 50 and the fastening portion 42 can be suppressed as compared with the case where the fastening index is provided on the entire target tape 50.

  As shown in FIG. 2B, the center index 51 and the fixing indices 52 to 54 are formed on the outer surface 50a of the target tape 50 by embossing and are formed as recesses that are recessed toward the inner surface 50b side. . The concave portion is formed by consolidation of a sheet constituting the target tape 50 by the embossing. When the target tape 50 is made of a fiber sheet such as a knitted fabric or a nonwoven fabric, the fiber sheet is formed into a film by heat applied by embossing, so that a recess is formed, and the recess is in a smooth state. It is preferable from the viewpoint of facilitating the perception of the center index 51 and the fixation indices 52 to 54. In the example shown in FIG. 2B, the depth from the outer surface 50a of the target tape 50 is substantially constant, but the bottom surfaces of the concave portions constituting the center index 51 and the fastening indices 52 to 54 may be different. .

  As described above, in the present embodiment, the center index 51 and the fixing indices 52 to 54 are formed in the concave portions having a predetermined shape in the plan view of the target tape 50, so that they are perceived by tactile sensation. It is. From the viewpoint of making the center index 51 more perceptible with tactile sensation, the maximum width L51 (see FIG. 2A) of the center index 51 in the width direction Y is preferably 1 to 15 mm, and more preferably 5 -10 mm.

  In this embodiment, the area of the sticking index is made different for each group, so that the sticking indices of each pair are formed so as to exhibit different tactile sensations. In the present embodiment, the area of the fastening index is the bottom area of the recess that constitutes the fastening index. As shown in FIG. 2 (a), each set of anchoring indicators has a constant length in the longitudinal direction X, and the length in the width direction Y is farther from the center index 51 than the anchoring indicators of the pair. It is formed to be smaller. As a result, the area of the set index farther from the center index 51 is smaller. By forming the sticking index in this way, it becomes easier to perceive the sticking index when the fingers of each hand touching the central index 51 are moved toward the left and right of the target tape 50.

  In the present embodiment, the center index 51 is formed over the entire area of the target tape 50 in the longitudinal direction X, whereas each set of fixing indices includes the upper edge of the target tape 50, It is biased to the upper end side of the tape 50. Thus, the tactile sensation is also greatly different between the center index 51 and the fastening index of each set due to the great difference in their shapes. Therefore, it is easy to find the center index 51 with a finger, distinguishing it from the fixation index.

  It is preferable that the fixing indices of each group are provided 5 mm or more apart, particularly 5-30 mm apart. As shown in FIG. 2 (a), an interval between two adjacent sets of fixing indices, for example, an interval Ls1 between the fixing indices 52, 52 and the fixing indices 53, 53, and the fixing indices 53, 53 and the fixing indices. The distance Ls2 between the indicators 54 and 54 is preferably 5 mm or more. Therefore, when the fixation index is confirmed by the finger pad, the region between the fixation indices can be reliably perceived by tactile sense, and each of the two adjacent fixation indices can be reliably recognized independently.

  Further, the distance Lx (see FIG. 2A) between the lower end portions of the fastening indexes 52 to 54 and the lower end edge 50d of the target tape 50 is set to the fastening width L42 (FIG. 1) of the fastening tapes 40 and 40. It is also preferable to be equal to or more than As shown in FIG. 1, the fastening width L <b> 42 is the maximum width in the longitudinal direction X at the fastening portions 42 of the fastening tapes 40, 40. Since the distance Lx is equal to or larger than the fastening width L42, the fastening portion 42 of the fastening tape 40 can be easily fastened to a region where the fastening index of the target tape 50 is not provided. A decrease in the engaging force of the target tape 50 due to the provision of the index can be prevented.

Next, the disposable diaper of 2nd thru | or 11th embodiment is demonstrated with reference to FIG. 3 thru | or FIG. About the disposable diaper of 2nd thru | or 11th embodiment, a difference with 1st Embodiment is mainly demonstrated and description is abbreviate | omitted about the same point. The points that are not particularly described are the same as in the first embodiment. 3 to 12, the same reference numerals are given to the same components as the disposable diaper components of the first embodiment.
Each of the disposable diapers of the second to eighth embodiments is obtained by replacing the target tape 50 in the disposable diaper of the first embodiment with each of the target tapes 50A to 50G shown in FIGS.

  The target tape 50A in the second embodiment shown in FIG. 3 is provided with one or more small convex portions 56 in the concave portions constituting the fixing indexes 52A to 54A. Specifically, as shown in FIG. 3B, the small convex portion 56 protrudes from the bottom surface of each concave portion. The presence of such small convex portions 56 makes it easier to perceive each fastening index with a tactile sensation. The ratio (H / D) of the height H (see FIG. 3 (b)) of the small convex portion 56 to the depth D (see FIG. 3 (b)) of the recess is 0.5 to 1.5. preferable. The small convex portion 56 can be formed simultaneously with the formation of the concave portion by performing embossing using an embossing roll having a concave portion constituting the fastening index and an uneven portion corresponding to the shape of the small convex portion 56.

  As shown in FIG. 3A, the small convex portions 56 are provided along the width direction Y at substantially the same position in the longitudinal direction X of the target tape 50A. The number of small convex portions 56 arranged in each of the concave portions constituting each set of fixing index is different, and thereby the difference in tactile sensation of each fixing index becomes large. In the example shown in FIG. 3, a larger number of small convex portions 56 are arranged in the concave portion that constitutes a larger fastening index.

  In the form shown in FIG. 3B, the inner surface 50b side (the lower side in FIG. 3B) of the formation portion of the small convex portion 56 in the target tape 50A is formed flat. Instead, as shown in FIG. 3C, a small concave portion 57 is formed on the inner surface 50b side of the small convex portion 56, which is recessed toward the protruding direction of the small convex portion 56, that is, toward the outer surface 50a side of the target tape 50A. May be. Such a small concave portion 57 is formed by rotating one roll having a concave portion and another roll having a convex portion while meshing the concave portion and the convex portion while sandwiching the target tape. By forming 56, it forms with the small convex part 56. FIG. Thus, it is preferable to form the small convex portion 56 on the outer surface 50a side together with the small concave portion 57 on the inner surface 50b side because the small convex portion 56 can be easily formed with a clear tactile feeling.

  In the third embodiment shown in FIG. 4, each fixing index 52B to 54B formed on the target tape 50B is biased toward the upper end side of the target tape 50B, but does not extend to the upper end edge 50c. Further, the respective fixing indexes 52B to 54B are formed in a substantially circular shape. The centers of the respective fixing indexes 52B to 54B are located on one straight line. This straight line is parallel to the width direction Y of the target tape 50. In addition, the diameters of the fastening indices 52B to 54B gradually decrease from the central index 51 toward the left and right sides of the target tape 50B.

  In the fourth embodiment shown in FIG. 5, the center index 51C is a notch portion cut from the upper end edge 50c of the target tape 50C. The notch is formed in a substantially isosceles triangular shape with the upper edge 50c as a base. On the other hand, each fastening index 52 to 54 is a recess as in the embodiment shown in FIG. As described above, the central index 51C and the fastening indices 52 to 54 are formed in different shapes such as a recess and a notch, so that the central index 51C and the fastening indices 52 to 54 are more clearly distinguished by tactile sense. can do. Thereby, the position of the fastening index can be identified more easily. As shown in FIG. 5, in the target tape 50C, the center index 51C is provided so as to be biased toward the upper end side of the target tape, and the fastening indices 52 to 54 are arranged on the same side as the side on which the center index 50C is biased.

In particular, when printing such as a pattern for visually perceiving the fastening position of the fastening tape and a fastening index for making it sense by tactile sense are combined, the image visually shown in a bright place will appear in a dark place. When the fixation index is perceived by tactile sensation, it appears in the back of the brain, making it easy to understand the position of the fixation index. That is, a combination of printing of a pattern or the like and a fastening index is preferable because the printing of the pattern or the like plays a role of assisting position confirmation by tactile sensation using the fastening index.

  In the embodiment shown in FIGS. 2 to 12, the example is shown in which the area of the set of sticking indices farther from the central index 51 is smaller, but the order of arrangement of the sticking indices is not limited thereto. I can't. For example, contrary to the embodiment shown in FIG. 2 to FIG. 12, it may be formed such that the area of the fixing index that is farther from the center index is larger. Even if the fixation index is formed in this way, it is easy to perceive the fixation index when the fingers of each hand touching the center index 51 are moved toward the left and right of the target tape 50.

  In addition, the description omitted in one embodiment and the requirements of only one embodiment can be applied to other embodiments as appropriate, and the requirements in each embodiment can be appropriately applied between the embodiments. Can be substituted for each other.
