Description

  The present invention relates to a diaper that absorbs body fluid of a wearer.

  DESCRIPTION OF RELATED ART Conventionally, what has a fastening tape is known as a disposable diaper for adults or infants. A disposable diaper having a fastening tape is fixed to the wearer by fastening a pair of fastening tapes provided on both sides of the back portion to a frontal tape provided on the front abdomen.

  In particular, in recent years, disposable diapers have been proposed that assume that two tabs provided on a fastening tape are stacked on a frontal tape. In such a disposable diaper, the tabs are overlapped on one tab so as to cross each other, and both tabs are fixed to the frontal tape. Thereby, a disposable diaper is fixed to a wearer, tightening a wearer's waist circumference and leg circumference.

  Conventional disposable diapers are disclosed in Patent Documents 1 and 2, for example.

  When the two tabs are overlapped in the vicinity of both sides of the frontal tape, it is preferable to intersect the two tabs at a large angle in order to obtain a high tightening force. In other words, it is preferable that the upper tab is pulled largely downward, and the lower tab is pulled largely upward to prevent the overlap.

  On the other hand, when two tabs are to be overlapped in the vicinity of the center of the frontal tape, if the two tabs are crossed at a large angle, the tightening force may be excessive. For this reason, in order to reduce a wearer's feeling of pressure, it is preferable to make two tabs cross at a small angle (an angle close to parallel).

  However, conventionally, when wearing a disposable diaper, the angle of the above-mentioned stacking stop has been set based on the wearer's own experience or the caregiver's experience. For this reason, depending on the wearer or the caregiver, it is possible that the stacking is stopped at an inappropriate angle, and the tightening force is excessively large or small.

  This invention is made | formed in view of such a situation, and it aims at providing the diaper which can carry out the two tabs of the fastening tape on the frontal tape at an appropriate angle according to the fastening position. To do.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

<1. Diaper according to one embodiment>
FIG. 1 is a perspective view of a disposable diaper 1 according to an embodiment of the present invention. FIG. 2 is a plan view of the disposable diaper 1 as viewed from the top sheet 10 side. FIG. 3 is a plan view of the disposable diaper 1 as viewed from the back sheet 20 side. FIG. 4 is a cross-sectional view of the disposable diaper 1 viewed from the position IV-IV in FIG. 2 and 3 show a state where a side seat elastic member 41, a waist elastic member 51, and a leg elastic member 52, which will be described later, are all extended.

  As shown in FIGS. 1 to 4, the disposable diaper 1 includes a liquid-permeable top sheet 10, a liquid-impermeable back sheet 20, and an absorber 30 interposed between both sheets 10 and 20. A diaper main body 2 is provided. When the wearer of the disposable diaper 1 excretes body fluid such as urine, the body fluid passes through the top sheet 10 but does not pass through the back sheet 20 and is absorbed between the top sheet 10 and the back sheet 20. Absorbed and held by the body 30.

  The diaper main-body part 2 has the front part 2a addressed to a wearer's abdominal surface, the back part 2b addressed to a wearer's back surface, and the crotch part 2c which connects the front part 2a and the back part 2b. . Hereinafter, a direction in which the front abdominal part 2a, the crotch part 2c, and the back part 2b are connected is referred to as a “longitudinal direction”, and a direction perpendicular to the longitudinal direction and along the surface of the diaper main body 2 is referred to as a “width direction”. The diaper main body 2 extends in the longitudinal direction from the front abdominal part 2a to the back part 2b, and has a shape constricted in the width direction at the crotch part 2c located in the middle.

  The top sheet 10 is a liquid-permeable sheet disposed inside the absorbent body 30 (side closer to the wearer's skin). The top sheet 10 extends in a band shape from the front abdominal part 2a to the back part 2b, and the dimension in the width direction is smaller than the dimension in the width direction of the outer edge of the diaper body part 2. The top sheet 10 of the present embodiment is made of a nonwoven fabric that is made liquid permeable by treating the surface of hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) with a surfactant. The top sheet 10 may be composed of a nonwoven fabric using hydrophilic fibers (cellulose, rayon, cotton, etc.).

  The back sheet 20 is a liquid-impermeable sheet disposed on the outside of the absorber 30 (the side far from the wearer's skin). The backsheet 20 has substantially the same shape as the diaper main body 2 in plan view. That is, the back sheet 20 covers the entire outer surface of the diaper main body 2. The back sheet 20 of the present embodiment is made of a plastic film. In addition, the back sheet 20 may be comprised by the plastic film and the highly flexible nonwoven fabric affixed on the outer surface. The back sheet 20 may be made of a water-repellent nonwoven fabric using hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.).

  The absorber 30 is a member having liquid absorbency and liquid retention. As shown in FIG. 4, the absorber 30 is fixed between the top sheet 10 and the back sheet 20 with an adhesive 91. The absorber 30 is, for example, a paper sheet such as tissue paper or a liquid-permeable material obtained by mixing a hydrophilic fiber such as pulverized pulp fiber or cellulose fiber and a granular superabsorbent polymer (SAP). It is coated with a non-woven sheet. The absorber 30 may be formed by molding only a superabsorbent polymer into a sheet shape.

  Inside the top sheet 10, a pair of side sheets 40 are provided for preventing leakage of body fluid to the side. The pair of side sheets 40 extends in the longitudinal direction so as to cover the left and right sides of the diaper main body 2. Each side sheet 40 is made of a water-repellent nonwoven fabric using hydrophobic fibers (polypropylene, polyethylene, etc.). As shown in FIG. 4, the pair of side sheets 40 is bonded to the inner side surface of another sheet via an adhesive 91 on the outer side in the width direction. The portion on the inner side in the width direction of the side sheet 40 is not attached to the inner side surface of the top sheet 10 and can rise with respect to the top sheet 10.

  A plurality of side sheet elastic members 41 extending in the longitudinal direction are provided on the side edge of the side sheet 40 on the inner side in the width direction. At the time of manufacturing the disposable diaper 1, the elastic member 41 for the side sheet is attached to the side sheet 40 in a state where the elastic member 41 is extended from the natural length. For this reason, the elastic member 41 for side sheets generates the elastic force which shrinks the side sheet 40 to a longitudinal direction. When the disposable diaper 1 is opened, the side edge of the side seat 40 on the inner side in the width direction rises due to the elastic force of the side seat elastic member 41. As a result, a pair of upstanding weirs is formed on the inner surface of the diaper main body 2.

  A plurality of waist elastic members 51 extending in the width direction are provided on the front abdomen 2a and the back part 2b. The waist elastic member 51 is fixed between the top sheet 10 and the back sheet 20 with an adhesive (not shown). At the time of manufacturing the disposable diaper 1, the waist elastic member 51 is attached to the front abdomen 2a and the back part 2b in a state of being extended more than the natural length. For this reason, the waist elastic member 51 generates an elastic force that contracts the front part 2a and the back part 2b in the width direction. When the wearer wears the disposable diaper 1, the front abdomen 2 a and the back part 2 b fit around the waist of the wearer due to the contraction force of the waist elastic member 51.

  Further, a plurality of leg-around elastic members 52 extending in the longitudinal direction are provided on both side edges in the width direction of the crotch portion 2c. The leg-around elastic member 52 is fixed between the side sheet 40 and the back sheet 20 with an adhesive (not shown). When the disposable diaper 1 is manufactured, the leg-hole elastic member 52 is attached to both side edges of the crotch portion 2c in a state where the elastic member 52 is extended beyond the natural length. For this reason, the leg-hole elastic member 52 generates an elastic force that contracts both side edges of the crotch 2c in the longitudinal direction. When the wearer wears the disposable diaper 1, both side edges of the crotch 2 c fit around the leg of the wearer due to the contraction force of the leg elastic member 52.

  In the present embodiment, a thread-like elastic member made of polyurethane is used for the side seat elastic member 41, the waist elastic member 51, and the leg elastic member 52. However, instead of the thread-like elastic member, a flat elastic member made of polyurethane, natural rubber or the like may be used.

  The disposable diaper 1 includes a pair of fastening tapes 60. The fastening tape 60 has a fastening main body 61 and two tabs (hereinafter referred to as an upper tab 62 and a lower tab 63). The fastening body 61, the upper tab 62, and the lower tab 63 are integrally formed of a nonwoven fabric such as polypropylene, for example. The base end portion of the fastening main body 61 is fixed to the left and right side edges of the back portion 2b. Specifically, the base end portion of the fastening main body portion 61 is fixed between the side sheet 40 and the backsheet 20 with an adhesive (not shown).

  The upper tab 62 and the lower tab 63 extend outward in the width direction from the end of the fastening main body 61 on the free end side. Two fastening members 64 are respectively fixed to the inner surfaces of the upper tab 62 and the lower tab 63 with an adhesive (not shown). As shown in FIGS. 1 to 3, the two fastening members 64 are arranged at intervals in the width direction. In the present embodiment, hook members (male members) of hook-and-loop fasteners are used for the fastening members 64.

  On the other hand, as shown in FIGS. 1 and 3, a frontal tape 70 is provided on the outer surface of the front part 2 a of the main body 2. The frontal tape 70 is fixed to the outer surface of the front abdomen 2a with an adhesive (not shown). In this embodiment, a loop material (female member) of a hook-and-loop fastener is used for the frontal tape 70. The fastening members 64 of the upper tab 62 and the lower tab 63 can be detachably attached to arbitrary positions on the surface of the frontal tape 70.

  When the disposable diaper 1 is worn, first, the rear back part 2b, the crotch part 2c, and the front abdomen 2a of the diaper main body part 2 are respectively applied to the back, crotch, and abdomen of the wearer. Subsequently, the upper tabs 62 of the left and right fastening tapes 60 are pulled out toward the wearer's abdomen, and the fastening member 64 of the upper tab 62 is fastened to the surface of the frontal tape 70. Thereby, the disposable diaper 1 is fixed around a wearer's waist.

  Thereafter, the lower tabs 63 of the left and right fastening tapes 60 are pulled out toward the wearer's abdomen, and the fastening member 64 of the lower tab 63 is fastened to the surface of the frontal tape 70. At this time, the lower tab 63 is crossed over the upper tab 62 that has been fastened first, and the stacking is stopped. Thereby, the circumference | surroundings of a wearer's leg are fastened and it suppresses that a clearance gap generate | occur | produces around a wearer's leg.

<2. About Frontal Tape Patterns>
Next, the pattern attached to the frontal tape 70 will be described. FIG. 5 is a plan view of the frontal tape 70. As shown in FIG. 5, the frontal tape 70 includes a pair of pattern areas 71 having a corrugated pattern 80 and a center area 72 disposed between the pair of pattern areas 71.

  The waveform pattern 80 attached to the pattern area 71 is composed of a plurality of convex figures 81 to 89. In this example, the figures 84 to 86 are arranged outside the figures 81 to 83 in the width direction. Further, graphics 87 to 89 are arranged on the outer side in the width direction of the graphics 84 to 86.

  Each of the figures 81 to 89 has a convex shape that protrudes toward the center of the frontal tape 70. Accordingly, each of the figures 81 to 89 includes a first guide line 80a that extends obliquely so as to approach the crotch 2c side toward the center in the width direction of the frontal tape 70, and a crotch 2c as it approaches the center in the width direction of the frontal tape. And a second guide line 80b extending obliquely so as to be separated from the center.

  The angle θ1 formed between the first guide line 80a and the second guide line 80b in the graphics 81 to 83 is smaller than the angle θ2 formed between the first guide line 80a and the second guide line 80b in the graphics 84 to 86. Further, the angle θ2 formed between the first guide line 80a and the second guide line 80b in the graphics 84 to 86 is smaller than the angle θ3 formed between the first guide line 80a and the second guide line 80b in the graphics 87 to 89. That is, as the figure is closer to the center of the frontal tape 70, the angle formed by the first guide line 80a and the second guide line 80b is smaller.

  The frontal tape 70 of the present embodiment has a structure in which a loop layer in which nylon fibers are knitted in a lattice shape is bonded to the upper surface of a film layer formed of a polypropylene film (OPP film). The corrugated pattern 80 may be printed in advance on a film layer before bonding, for example.

  FIG. 6 is a view showing a state in which the upper tab 62 and the lower tab 63 are fixed in the vicinity of both side portions of the frontal tape 70. In the example of FIG. 6, the upper tab 62 is disposed along the first guide line 80 a of the graphic 89, and the lower tab 63 is disposed along the second guide line 80 b of the graphic 87. Therefore, the upper tab 62 and the lower tab 63 are overlapped with each other at an angle larger than that in FIG. As a result, the wearer's waist and legs are securely tightened.

  FIG. 7 is a view showing a state where the upper tab 62 and the lower tab 63 are fastened near the center of the frontal tape 70. In the example of FIG. 7, the upper tab 62 is disposed along the first guide line 80 a of the graphic 83, and the lower tab 63 is disposed along the second guide line 80 b of the graphic 81. For this reason, the upper tab 62 and the lower tab 63 are overlapped with each other at an angle smaller than that in FIG. As a result, excessive tightening around the waist and legs is suppressed.

  As described above, the frontal tape 70 of this embodiment is printed with the corrugated pattern 80 that serves as a guide for the fastening angle of the upper tab 62 and the lower tab 63. If the upper tab 62 is disposed along the first guide line 80a in the corrugated pattern 80 and the lower tab 63 is disposed along the second guide line 80b in the corrugated pattern 80, the upper tab 62 and the lower tab 63 are Can be stacked at an appropriate angle according to the fastening position.

  In particular, in the present embodiment, the first guide line 80a and the second guide line 80b are part of the convex figures 81-89. That is, both the first guide line 80a and the second guide line 80b are included in the series of convex figures 81-89. Therefore, the entire waveform pattern 80 can be simplified while including the first guide line 80a and the second guide line 80b.

  Further, the upper tab 62 and the lower tab 63 of the present embodiment have arcuate corners 62a and 63a. On the other hand, each of the convex figures 81 to 89 of the present embodiment has a wave shape constituted by a curve. The tip portion 80c of each of the figures 81 to 89 is formed in an arc shape. For this reason, when the stacking is stopped, the corners 62a and 63a of the upper tab 62 and the lower tab 63 are easily arranged in the vicinity of the tip 80c of each of the figures 81 to 89.

  In the present embodiment, the plurality of figures 81 to 89 are arranged not only in the width direction but also in the longitudinal direction. For this reason, the fixing position of the longitudinal direction of the upper tab 62 and the lower tab 63 in the frontal tape 70 can be selected according to a wearer's body shape. 6 and 7, the upper tab 62 and the lower tab 63 are arranged along separate figures, but the upper tab 62 and the lower tab 63 are included in the same figure. You may arrange | position along the 1st guide line 80a and the 2nd guide line 80b.

  It is preferable that the 1st guide line 80a and the 2nd guide line 80b contained in the figures 81-89, and the upper tab 62 and the lower tab 63 of the fastening tape 60 are the same color or an approximate color. By doing so, the correspondence relationship between the first guide line 80a and the second guide line 80b and the upper tab 62 and the lower tab 63 becomes visually clearer. Therefore, the user can be prompted to arrange the upper tab 62 and the lower tab 63 along the first guide line 80a and the second guide line 80b.

  The graphics 81 to 89 may all be drawn in the same color, but the colors of the graphics 81 to 89 may be different. If the colors of the graphics 81 to 89 are made different according to the position in the width direction, it becomes easier to specify the fastening position suitable for the body shape of each wearer. Moreover, it becomes easy to visually recognize the fastening position in the width direction and the fastening angle suitable for the fastening position.

  A belt-like central region 72 is provided at the center in the width direction of the frontal tape 70. Although the size of the disposable diaper 1 is written in the central region 72, the corrugated pattern 80 is not arranged. For this reason, when it is going to arrange | position the upper tab 62 and the lower tab 63 along the waveform pattern 80, the attachment of the upper tab 62 and the lower tab 63 to the center area | region 72 is suppressed naturally. For this reason, excessive tightening by the upper tab 62 and the lower tab 63 is further suppressed.

<3. Modification>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

  FIG. 8 is a plan view of a frontal tape 170 according to a modification. In the example of FIG. 8, the frontal tape 170 is provided with a lattice pattern 180 composed of a plurality of substantially rhombus figures. The lattice pattern 180 includes a plurality of convex figures 181 to 197 having a first guide line 180a and a second guide line 180b. And, as the figure is closer to the center of the frontal tape 170, the angle θ between the first guide line 180a and the second guide line 180b is smaller.

  Therefore, even in such a lattice pattern 180, if the upper tab is arranged along the first guide line 180a and the lower tab is arranged along the second guide line 180b, the upper tab and the lower tab are stopped. Can be stacked at an appropriate angle according to the wearing position.

  The first guide line and the second guide line may be continuous lines as in the example of FIG. 5, or may be dotted lines as in the example of FIG. Moreover, you may be comprised so that a 1st guide line and a 2nd guide line may be recognized as a whole by arranging a some figure and picture regularly. In addition, the boundary between the two color regions may constitute a first guide line and a second guide line.

  5 and 8, the plurality of convex figures are arranged in the width direction and the longitudinal direction. However, as shown in FIG. 9, the convex figures 281 to 285 are arranged only in the width direction. It may be arranged.

  Also in the example of FIG. 9, the first guide line 280 a and the second guide line 280 b are included in each of the convex figures 281 to 285. And the angle θ formed by the first guide line 280a and the second guide line 280b is smaller as the figure is closer to the center of the frontal tape 270. Therefore, if the upper tab is disposed along the first guide line 280a and the lower tab is disposed along the second guide line 280b, the upper tab and the lower tab are overlapped at an appropriate angle according to the fastening position. I can stop it.

  Moreover, although the frontal tape of the said embodiment was comprised with the loop material, the frontal tape may be comprised with another raw material. For example, the frontal tape may be composed of a raised nonwoven fabric, and a pattern including a first guide line and a second guide line may be printed on the nonwoven fabric. One or both of the fastening member and the frontal tape may be made of an adhesive material.

  Further, the frontal tape may be made of a material having high light transmittance, and a pattern including the first guide line and the second guide line may be printed on the surface of the back sheet. Even in such a form, the upper tab and the lower tab can be arranged along the pattern transcribed on the frontal tape.

  Further, in the above embodiment, the fastening tape has the fastening main body, but the fastening tape of the present invention does not necessarily have to have the fastening main body. For example, the base end portions of the upper tab and the lower tab may be directly joined to both sides of the back portion.

  Moreover, the diaper of this invention may absorb not only a wearer's urine but other body fluids, such as a loose stool. Moreover, the diaper of the present invention may be intended for an adult or may be intended for an infant.

  Moreover, you may combine suitably each element which appears in said embodiment and modification in the range which does not produce inconsistency.
