Description

  The present invention relates to an absorbent article including an absorbent body, a top sheet made of a liquid permeable material, and a back sheet made of a liquid impermeable material. Specifically, the present invention relates to an absorbent article further provided with a penis fixing sheet for fixing a wearer's penis.

  In recent years, a disposable diaper and a urine pad (also referred to as “inner pad”, “auxiliary pad”, etc.) have been used in combination in order to reduce labor when changing the diaper. By using the urine pad together, even if the wearer excretes, it is sufficient to replace only the urine pad, and the disposable diaper can be used as it is. Since such a method is easier to replace than a method of replacing the entire disposable diaper every time it is excreted, the caregiver's labor is reduced. Moreover, since a urine pad is cheaper than a disposable diaper, it is advantageous in terms of cost compared with a method of exchanging the entire disposable diaper every time it is excreted.

  Usually, the urine pad is used in such a manner that the urine pad is laid flat on the surface of the disposable diaper on the top sheet side, and the disposable diaper in a state where the urine pad is laminated is applied to the wearer's skin. On the other hand, as a urine pad specialized for men, a urine pad that encapsulates the penis or inserts the penis into a bag is also known. For example, a urine pad (for example, see Patent Documents 1 to 3) of a type in which an adhesive part is formed and the penis can be fixed in a corn-like (sac-like) state with a urine pad, or a bag in advance There is known a urine pad (see, for example, Patent Document 4) that is formed in a shape and is configured such that a penis can be inserted into the bag.

  However, the urine pad as described above is troublesome to wear due to its structure, and the urine pad is easily detached from the penis even after being worn once, and leakage cannot occur because the urine pad cannot be maintained. There was a problem that it was easy. In particular, when used on a person with penile atrophy such as an elderly person, it is difficult to sufficiently fix the urine pad to the penis, and there is a high risk that the urine pad may come off from the penis. Met.

  In order to cope with the above-mentioned problem, a method of laying a urine pad in a disposable diaper is used for a male elderly person like a female. However, in such a method of use, urine may leak from the front end portion (abdominal end portion) or the left and right side edge portions of the urine pad depending on the orientation of the penis when the disposable diaper and the urine pad are worn. When urine leaks from the front edge of the urine pad or from the left and right side edges, the urine pad is hardly soiled, and the leak occurs despite the remaining capacity of the absorber. Occurs. Further, when the urine pad is used in a flat state, not only the penis but also the scrotum is exposed to the urine, so that there is a problem that the scrotum is easily rashed.

  And the problem that urine leaks from the front end of the diaper and the left and right side edges depending on the orientation of the penis when wearing, and the problem that the scrotum is likely to rash are not limited to urine pads, but also in disposable diapers Can occur.

  The present invention has been made in view of such problems of the prior art, and is an absorbent article that is less likely to leak, can effectively use the absorbent capacity of the absorbent body, and is less likely to cause scalp irritation. Is to provide.

  As a result of intensive studies to solve the problems of the prior art, the present inventor has provided a plurality of penis fixing sheets made of a water-repellent material and extending in the width direction of the absorbent article, and those sheets It is conceived that the above-mentioned problems can be solved by arranging the pendulum from anywhere between the sheets and arranging the pendant in parallel in the front-rear direction of the absorbent article.

  Hereinafter, the form for implementing the absorbent article of this invention is demonstrated concretely by the example of a urine pad and a pants-type disposable diaper. However, the present invention broadly encompasses absorbent articles having the invention specific items, and is not limited to the following embodiments.

[1] Definitions etc .:
The “urine pad” refers to the absorbent body 22, the top sheet 18 disposed so as to cover the surface of the absorbent body 22, and the back surface of the absorbent body 22, as in the absorbent article 1 </ b> A illustrated in FIGS. 1A to 1C. This means an absorbent article that does not have a portion that encloses the circumference of the wearer's waist, unlike a disposable diaper. The “urine pad” is also referred to as an inner pad or an auxiliary pad, and is generally used in a state of being placed on the inner surface of an undergarment or the top sheet of a disposable diaper.

  The “pants-type disposable diaper” is formed by joining the corresponding side edges 2a, 2b (6a, 6b) of the front body 2 and the back body 2 like the absorbent article 1C shown in FIGS. 3A and 3C. A disposable diaper having a waist opening 10 and a pair of leg openings 12 (12a, 12b) formed in advance in a pants shape.

  Then, like the absorbent article 1C shown in FIGS. 3A to 3D, an absorbent body 14 is included between the top sheet 18 and the back sheet 20, and is formed into a pad shape, and one waist. A "two-piece type" having an outer sheet 16 having a pant-like shape in which a peripheral opening 10 and a pair of leg peripheral openings 12 are formed, and an absorbent main body 14 disposed and fixed inside the outer sheet 16 Is often used.

  In this specification, as shown in FIG. 1A, the part addressed to the wearer's stomach side of the absorbent article 1A is referred to as “front body (reference numeral 2 in the figure)” and addressed to the wearer's inseam. The part is referred to as “crotch part (reference numeral 4 in the figure)”, and the part addressed to the wearer's back side (butt side) is referred to as “rear body part (reference numeral 6 in the figure)”.

  Further, in the present specification, when referring to the “length” with respect to the penis fixing sheet, as described with reference to FIG. 1A, the absorbent article 1A in a state where the penis fixing sheet 50A is joined to the absorbent article 1A regardless of the sheet shape. Means the length from the end on the front end E1 side to the end on the rear end E2 side of the absorbent article 1A (length in the front-rear direction). Similarly, regarding the penis fixing sheet, when it is referred to as “width”, it is absorbed from one side edge E3 of the absorbent article 1A in a state where the penis fixing sheet 50A is joined to the absorbent article 1A regardless of the sheet shape. The length (length in the left-right direction) to the other side edge E4 of the property article 1A is meant.

[2] Configuration of the absorbent article of the present invention:
The absorbent article of the present invention, like the absorbent article 1A shown in FIG. 1A to FIG. 1D, is arranged so that at least the surface is made of a water-repellent material and extends in the width direction of the absorbent article 1A, and both sides in the width direction. A plurality of penis fixing sheets 50A having edges joined to the top sheet 18 are provided, and the plurality of penis fixing sheets 50A are arranged in parallel in the front-rear direction of the absorbent article 1A. is there.

  As shown in FIG. 1D, when the penis fixing sheet 50A is provided, when the absorbent article 1A is mounted, the direction of the penis P is directed toward the rear end E2 side (inseam, back side) of the absorbent article 1A. Can be fixed. Therefore, it is difficult for the penis P to face the front end E1 side and the side edges E3 and E4 of the absorbent article 1A, and urine leakage from the front end E1 and the side edges E3 and E4 can be effectively prevented. And since the urine U flows toward the rear end E2 side (inseam side, back side) of the absorbent article 1A according to the direction of the penis P, the absorption disposed in the crotch part 4 and the back body 6 of the absorbent article 1A. The absorption capacity of the body 22 can also be fully exhibited.

  Moreover, as shown in FIG. 1D, when a plurality of penis fixing sheets 50A are provided and the plurality of penis fixing sheets 50A are arranged in parallel in the front-rear direction of the absorbent article 1A, each penis The penis P can be inserted from anywhere between the fixed sheets 50A. With this structure, it is possible to select a penis insertion position suitable for the wearer's physique and body shape. Therefore, it becomes difficult for the penis P to come off from the penis fixing sheet 50A, and urine leakage from the front end E1 and the side edges E3 and E4 of the absorbent article 1A can be effectively prevented. This structure is applied to tape type disposable diapers and pants type disposable diapers where the wearing position is determined in advance by the waist opening and leg opening, and it is difficult to shift the wearing position back and forth, such as a urine pad. It is valid.

  Further, when the penis P is inserted into the penis insertion portion 54A formed by the penis fixing sheet 50A, the scrotum S comes into contact with the surface of the penis fixing sheet 50A and is separated from the top sheet 18. Further, when at least the surface of the penis fixing sheet 50A (the entire penis fixing sheet 50A in the illustrated example) is made of a water-repellent sheet, the urine U adhering to the top sheet 18 oozes out from the penis fixing sheet 50A. Can be suppressed. Therefore, it is difficult for the urine U to directly contact the scrotum S, and the scrotum S can be effectively prevented from being rashed.

  In addition, when the absorbent article of the present invention is applied to a flat urine pad such as the absorbent article 1A, compared to a urine pad that encloses the penis or a urine pad that inserts the penis into a bag. The urine pad can be easily attached and the urine pad is unlikely to come off. Therefore, it is easy to maintain the state where the urine pad is addressed, and leakage can be effectively prevented.

[2-1] Penis fixation sheet:
The absorbent article of the present invention includes a penis fixing sheet 50A as in the absorbent article 1A shown in FIGS. 1A to 1D. By this penis fixing sheet 50A, the penis P is fixed so as to face the crotch side (or back side) of the absorbent article 1A.

  The penis fixing sheet 50A is arranged on the front end E1 side of the absorbent article 1A so as to extend in the width direction of the absorbent article 1A. “The front end side of the absorbent article” means that when the absorbent article 1A is divided into two at the longitudinal centerline, the penis fixing sheet 50A is arranged in the area on the front end E1 side. The penis fixing sheet 50A is disposed on the front end E1 side of the absorbent article 1A because the penis P is inserted from the front end E1 side of the absorbent article 1A into the penis insertion portion 54A formed by the penis fixing sheet 50A. This is because.

  The “width direction of the absorbent article” means a direction orthogonal to the front-rear direction of the absorbent article 1A. Usually, since an absorbent article is comprised in the shape long in the front-back direction, the longitudinal direction turns into the front-back direction, and a transversal direction turns into the width direction (left-right direction). By disposing the penis fixing sheet 50A so as to extend in the width direction of the absorbent article 1A, the penis P can be fixed so as to face the rear end E2 side (inseam, back side) of the absorbent article 1A. In addition, 50 A of penis fixing sheets are normally arrange | positioned in the width direction center part of 1 A of absorbent articles. And it is preferable to arrange | position to the upper part of the absorber 22 arrangement | positioning site | part of 1 A of absorbent articles from a viewpoint of making the urine U excreted from the fixed penis P fully absorb.

  The absorbent article of the present invention includes a plurality of penis fixing sheets 50A as in the absorbent article 1A shown in FIGS. 1A, 1C, and 1D, and the plurality of penis fixing sheets 50A are the absorbent articles 1A. It arrange | positions so that it may parallel in the front-back direction. The number of penis fixing sheets 50A varies depending on the shape and size, but is preferably 3 to 10 sheets. If the number is less than 3, the effect that the penis can be inserted from a plurality of locations may be insufficient. If it exceeds 10, it is preferable in that the penis can be inserted from a more appropriate position, but the structure becomes complicated and the manufacturing process may become complicated.

  In the absorptive article of the present invention, as long as the above conditions are satisfied, there is no particular limitation on the arrangement form of the plurality of penis fixing sheets. For example, a plurality of penis fixing sheets may be arranged at intervals (gap) so that the penis fixing sheets do not overlap each other. However, when there is a gap between the respective penis fixing sheets, there is an advantage that the penis can be easily inserted, but there is a possibility that urine leaks from the gap and wets the surface of the penis fixing sheet. In the unlikely event that urine adheres to the scrotum, it will not be possible to effectively prevent scalp irritation, which is not preferable.

  Therefore, in the absorbent article of the present invention, as in the absorbent article 1A shown in FIGS. 1A, 1C, and 1D, the front end portion of the penis fixing sheet 50A is adjacent to the rear end portion of one adjacent penis fixing sheet 50A. A structure in which the rear end portion of the penis fixing sheet 50A is arranged so as to partially overlap and the front end portion of the other adjacent penis fixing sheet 50A is partially overlapped is repeated. It is preferable that the penis fixing sheet 50A is disposed.

  As described above, since a plurality of penis fixing sheets 50A are arranged so as to partially overlap with the penis fixing sheets 50A arranged in the front and rear, gaps between the respective penis fixing sheets 50A are eliminated, so that leakage of urine occurs. Can be effectively prevented. As a result, the surface of the penis fixation sheet becomes difficult to get wet with urine, and the scrotum can be effectively prevented from being rash.

  The length (length in the front-rear direction) of the overlapping portion with the adjacent penis fixing sheet 50A is preferably 5 to 50 mm. If it is less than 5 mm, it is difficult to obtain the effect of overlapping the penis fixing sheets 50A. On the other hand, when it exceeds 50 mm, the overlapping part of 50 A of penis fixing sheets will become long too much, and 50 A of penis fixing sheets will cover the surface of the absorber 22 largely. Therefore, urine absorption from the surface of the absorber is hindered, and there is a possibility that the absorption performance of the absorbent article cannot be fully utilized.

  As described above, when the plurality of penis fixing sheets are arranged while partially overlapping the penis fixing sheets arranged in the front and rear, there is no particular limitation on the form in which the penis fixing sheets are superimposed. For example, like the absorbent article 1D shown in FIG. 4, the front end portion of the penis fixing sheet 50D is disposed below the rear end portion of one adjacent penis fixing sheet 50D, and the penis fixing portion is fixed. The structure in which the rear end portion of the sheet 50D is disposed so as to be positioned above the front end portion of another adjacent penis fixing sheet 50D is repeated, and a plurality of penis fixing sheets 50D are arranged. Can do.

  However, in the case of the form shown in FIG. 4, the interlayer gap between the two overlapped penis fixing sheets 50D opens toward the flow direction of the urine U. It is also possible that the urine U leaks out. Therefore, in the absorbent article of the present invention, as shown in FIGS. 1A, 1C, and 1D, the front end portion of the penis fixing sheet 50A is positioned above the rear end portion of one adjacent penis fixing sheet 50A. And a structure in which the rear end portion of the penis fixing sheet 50A is positioned below the front end portion of another adjacent penis fixing sheet 50A is repeated, and a plurality of penis fixing sheets 50A are repeated. Is preferably arranged.

  Unlike the form shown in FIG. 4, in the structure shown in FIG. 1D, the interlayer gap between two superimposed penis fixing sheets 50 </ b> A opens toward the side opposite to the flow direction of urine U. In this structure, as shown in FIG. 1D, even if the urine U is excreted in a large amount and vigorously, the urine U flows down on the surface of the top sheet 18 along the back surface of each penis fixing sheet 50A, and the two superimposed sheets It is possible to effectively prevent urine U from leaking from the interlayer gap of the penis fixing sheet 50A. Moreover, since the penis insertion part 54A is formed so as to open downward, there is an advantage that the penis P can be easily inserted into the penis insertion part 54A.

  The shape of the penis fixation sheet is not particularly limited, and may be any of those having a width larger than the length in the front-rear direction and those having a smaller width than the length in the front-rear direction. For example, the penis fixed sheet 50A shown in FIG. 1A is an example using a rectangular (strip-shaped) sheet having a width larger than the length in the front-rear direction.

  The width of the penis fixing sheet is preferably 60 mm or more and not more than the width of the absorbent article. If it is less than 60 mm, the width of the penis insertion part must be narrowed, and it becomes difficult to insert the penis. Further, when the width of the penis insertion portion is narrowed, the penis may not be inserted well even if the mounting position of the absorbent article is slightly shifted left and right. That is, there is a possibility that the allowable width with respect to the lateral displacement of the absorbent article is narrowed and the usability is deteriorated. On the other hand, the length of the penis fixing sheet is preferably 10 to 100 mm. When it is less than 10 mm, it is difficult to obtain an arrangement in which the penis fixation sheets 50A are sufficiently overlapped with each other, and it is difficult to obtain the effect of overlapping the penis fixation sheets. If it exceeds 100 mm, the effect that the penis insertion position suitable for the wearer's physique and body shape can be selected may be diminished.

  In addition, when a plurality of penis fixation sheets are arranged and the length between the foremost end to the rear end is configured to be 100 mm or more, the area where the penis fixation sheet covers the skin of the scrotum and other wearers is increased. To do. Accordingly, there is an advantage that the scrotum or the like is less likely to contact the surface of the top sheet, and skin troubles such as rash can be more effectively prevented. However, even if it is arranged too long as a plurality of penis fixing sheets as a whole, the increase in the effect cannot be expected, and the penis fixing sheet may worsen the feeling of wearing the crotch part. It is preferable to arrange so as not to exist in a portion exceeding the longitudinal center.

  However, the shape of the penis fixing sheet is not limited to the rectangular shape as described above. For example, like the penis fixing sheet 50B shown in FIG. 2A, the widthwise central portion at the rear end of the penis fixing sheet 50B has a shape cut out in an arc shape toward the front end side of the penis fixing sheet 50B. It is also preferable that the length of both side edges in the width direction is longer than the length of the center portion in the width direction.

  Like the penis fixing sheet 50B, the penis insertion part 54B is formed by forming the center part in the width direction so as to be recessed from both side edges in the width direction as compared with the case where the penis fixing sheet is formed in a simple rectangular shape. This makes it easier to insert the penis and makes it easier to fit. Moreover, even when the front end portion of the penis is directed to the left and right sides of the absorbent article 1B by configuring the side edges in the width direction to be long like the penis fixing sheet 50B, the lateral sides from the left and right side edges E3 and E4 Leakage can be effectively prevented. Furthermore, it is possible to sufficiently overlap other penis fixing sheets on both side edges of the penis fixing sheet. Therefore, even when the absorbent article has a curved shape as when worn, it is unlikely that the superimposed penis fixing sheets are separated from each other and the overlapping portion is largely opened.

  Under the present circumstances, it is preferable that the center part of the width direction of a penis fixed sheet is recessed 20-50 mm rather than the both-side edge part of the width direction. If it is less than 20 mm, the dent is too small and it is difficult to obtain effects such as easy insertion of the penis into the penis insertion portion. On the other hand, if it exceeds 50 mm, the penis fixed sheet tends to have a shape in which both side edges are extremely longer than the center. When a plurality of penis fixing sheets having such a shape are superimposed, the number of penis fixing sheets superimposed on both side edges often increases more than necessary. Therefore, the tactile sensation at both side edges of the penis fixing sheet becomes hard, and there is a possibility that the wearing feeling is lowered.

  Although the material which comprises a penis fixation sheet | seat is not specifically limited, At least the surface is comprised with a water-repellent material. For example, it is preferable to use a water-repellent nonwoven sheet. By the said structure, it is less likely that the urine adhering to a top sheet permeate | transmits a penis fixed sheet | seat, and reaches a scrotum, and can prevent the scrotum from rashing more effectively.

  As the water-repellent nonwoven sheet, the same material as the three-dimensional gather described later can be used. In addition, since the absorbent article of the present invention is sufficient if at least the surface of the penis fixing sheet is made of a water-repellent material, the surface of the penis fixing sheet (the surface on which the wearer's scrotum hits) is made of a water-repellent sheet. In addition, it is also preferable that the water repellent sheet has an absorptivity on the back surface (the surface on the side facing the top sheet). For example, 1) a form in which an absorber is lined on the back surface of a water-repellent sheet constituting the penis fixing sheet, 2) an absorber is lined on the back surface of the water-repellent sheet constituting the penis fixing sheet, and The back surface can be exemplified by a liquid-permeable (that is, hydrophilic) non-woven sheet similar to the top sheet lined. The absorber used in these forms may be made of pulp (such as fluff pulp) and SAP, or may be a simple absorber made only of tissue or absorbent paper.

  In addition, in order to improve the fixing force of a penis, you may attach an expansion-contraction material to a penis fixing sheet. In such a structure, the fixing force of a penis can be improved by attaching the expansion-contraction material extended toward the width direction of a penis fixing sheet. This form can be configured according to a solid gather described later.

  When attaching an elastic material to the penis fixing sheet, the arrangement position of the elastic material is not particularly limited. For example, the form arrange | positioned along the rear end of a penis fixed sheet | seat or between the front end and rear end of a penis fixed sheet | seat can be mentioned. Further, an elastic material may be arranged at each of these positions, and a plurality of elastic materials may be arranged as a whole.

  However, in the absorbent article of the present invention, as in the absorbent article 1E shown in FIG. 5, the penis fixed sheet elastic member 66 fixed in the stretched state is disposed along the front end of the penis fixed sheet 50E. It is preferable. Such a form is easily deformed so as to follow the shape of the penis inserted by the penis fixing sheet. Moreover, even when two penis fixing sheets are arranged in a superimposed manner, an interlayer gap is hardly formed, and leakage from the interlayer gap can be effectively prevented.

  Note that “along the front end of the penis fixing sheet” means that the penis fixing sheet elastic member 66 is arranged so as to be substantially parallel to the front end of the penis fixing sheet 50E, and the penis fixing sheet is divided into two along the longitudinal center line. In this case, it means that the penis fixing sheet stretchable material is disposed at least in the region on the front end side of the penis fixing sheet. More specifically, it is preferable to arrange within a range of 0 to 10 mm from the front end of the penis fixing sheet.

  A mode is also conceivable in which the penis fixed sheet stretchable material is disposed along the front end of the penis fixed sheet, and the penis fixed sheet stretchable material is disposed along the rear end of the penis fixed sheet. Such a form has an advantage that the penis fixing sheet can be easily fitted to the penis. However, depending on the stretch rate of the stretchable material, etc., 1) the resistance when inserting the penis into the penis insertion part is increased, 2) the penis may be compressed more than necessary while the absorbent article is mounted, 3) Since the urine flows downward, the penis fixation sheet elastic material is attached only along the front edge of the penis fixation sheet for the reason that the leakage prevention effect is small even if the elastic material is arranged on the rear end side of the penis fixation sheet. It is preferable to arrange.

  About the arrangement | positioning method and fixing method of a penis fixation sheet elastic material, the method of arrange | positioning and fixing a three-dimensional gather elastic material, a leg periphery elastic material, etc. is employable. The absorbent article 1E shown in FIG. 5 is an example in which the front end side of the penis fixing sheet 50E is partially folded, and the penis fixing sheet stretchable material 66 is sandwiched between the folded portions and fixed with an adhesive.

[2-2] Joint part:
In the absorbent article of the present invention, both side edges in the width direction of the penis fixing sheet 50A are joined to the top sheet 18 as in the absorbent article 1A shown in FIGS. 1A and 1B. More specifically, a first joint 52A that joins one side edge of the penis fixing sheet 50A and a second joint 52B that joins the other side edge of the penis fixing sheet 50A are formed. .

  By joining both side edges (ie, two locations) of the penis fixation sheet 50A to the top sheet 18, a penis insertion part 54A defined by the penis fixation sheet 50A and the top sheet 18 is formed. The “joining portion” can be formed by adhesion using an adhesive such as a hot melt adhesive, heat bonding by heating (heat sealing or the like), ultrasonic fusion, or the like.

  The “both edge portions of the penis fixing sheet” means a portion from each edge portion to 40% length with the longest portion of the penis fixing sheet as a reference (full width). In the present invention, as long as the penis fixing sheet 50A is not easily peeled off, it is not necessary that the entire area of both side edges of the penis fixing sheet 50A is joined to the surface of the top sheet 18, and both side edges of the penis fixing sheet 50A are used. It suffices that at least a part of the region is bonded to the surface of the top sheet 18. However, in order to ensure reliable joining, like the absorbent article 1A shown in FIG. 1A, the first joining portion 52A and the second joining portion 52B are continuously formed from the front end to the rear end of the penis fixing sheet 50A. Is preferably formed.

  In order to reliably join the penis fixing sheet and the top sheet, a form in which the first joint portion and the second joint portion are formed in a continuous surface shape is preferable. However, the absorbent article of the present invention is arranged such that the first joint portion 52C and the second joint portion 52D extend in the front-rear direction of the penis fixing sheet 50B as in the absorbent article 1B shown in FIGS. 2A to 2C. The plurality of linear joint portions 56a, 58a, 60a, 62a, 56b, 58b, 60b, and 62b may be formed. As described above, the configuration in which the joint portion is configured as a set of a plurality of linear joint portions is high-speed production when the absorbent article is continuously produced, as compared with the configuration in which the entire joint portion is configured in a planar shape. It is easy to use, and the amount of adhesive used for bonding can be reduced, which is preferable in terms of cost.

  2A to 2C, a plurality of linear joint portions 56a, 58a, 60a, 62a, 56b, 58b, 60b, and 62b are arranged on the center side in the width direction of the penis fixing sheet 50B ( The length of the ones (linear joints 60a, 62a, 60b, 62b) arranged on the side edge side of the penis fixing sheet 50B is longer than the length of the linear joints 56a, 58a, 56b, 58b). It is preferable that they are arranged as described above.

  In the above-mentioned form, the width of the penis insertion part is changed from the front end side (abdominal side) to the rear end side (inseam) of the penis fixing sheet as compared with the case where the lengths of the linear joint parts are all formed equal. Narrower toward the side and back). Therefore, the excreted urine is easily converged toward the center in the width direction of the absorbent article. Moreover, since the linear junction part of the both-sides edge side of a penis fixed sheet | seat is long, it is preferable at the point which can prevent side leakage from the right-and-left both-sides edge of a urine pad effectively. In addition, in the absorbent article 1B shown in FIG. 2A, the lengths of the linear joint portions 60a, 62a, 60b, and 62b are formed to be equal, but it is not limited to such a form. For example, the length of the linear joint portions 60a and 60b is set to an intermediate length between the linear joint portions 58a and 58b and the linear joint portions 62a and 62b, and as the penis fixed sheet 50B moves from the center in the width direction toward the side edge. The length of the linear joint may be gradually increased.

  The width of the linear joint is preferably 1 to 20 mm. If it is less than 1 mm, the bonding strength is low, and the penis fixing sheet may be detached from the top sheet. If it exceeds 20 mm, the number of linear joint portions that can be arranged decreases, and it becomes difficult to gradually change the length of each linear joint portion as compared with the case where the number of linear joint portions is large. In other words, it is necessary to adopt a form in which a plurality of linear joints are rapidly shortened from the side edge side in the width direction of the penis fixing sheet toward the center side, and smooth urine in the width direction center part of the absorbent article It becomes difficult to converge to.

  When the linear joint portion is formed with a width of 1 to 20 mm, the interval at which the plurality of linear joint portions are arranged is preferably 1 to 20 mm. If it is less than 1 mm, the distance between the linear joints is too narrow and there is no great difference from the one applied to a continuous surface, so that it becomes difficult to perform high-speed production when continuously producing absorbent articles and is used for joining. The amount of adhesive cannot be effectively reduced, and it is difficult to obtain a merit in terms of production cost. When it exceeds 20 mm, since the space | interval of linear junction parts is too wide, the urine excreted to the width direction center part of an absorbent article may be unable to be converged well.

  The absorbent article of the present invention is, as in the absorbent article 1B shown in FIGS. 2A to 2C, the widths W1 and W2 of the penis insertion part 54B formed between the first joint part 52C and the second joint part 52D. However, it is preferable that the absorbent article 1A is configured to become narrower from the front end E1 side to the rear end E2 side (that is, from the abdomen side to the crotch side and the back side) (W1> W2). In such a configuration, even when urine is excreted inside the penis insertion portion 54B, the urine is converged toward the center in the width direction of the absorbent article 1B. Therefore, urine leakage from the side edges E3 and E4 of the absorbent article 1B can be effectively prevented. In addition, for a wearer who cannot sufficiently fix the penis by the penis fixing sheet 50B and easily moves the penis inside the penis insertion portion 54B, such as a person with atrophy of the penis (such as an elderly man). It can be used suitably.

  In the present invention, as shown in FIG. 2A, the width W2 of the penis insertion portion 54B (that is, the exit width of the penis insertion portion 54B) at the end of the plurality of penis fixation sheets 50B is the maximum width of the plurality of penis fixation sheets 50B. What is necessary is just to be narrower than the width W1 of the penis insertion part 54B at the front end (that is, the entrance width of the penis insertion part 54B). The degree of narrowness is not particularly limited, and the width W2 of the penis insertion portion 54B at the rearmost end of the plurality of penis fixation sheets 50B is 30 with respect to the width W1 of the penis insertion portion 54B at the foremost end of the plurality of penis fixation sheets 50B. A width of ˜80% is preferred.

  If it is less than 30%, the width W2 is too narrow, and urine may not be sufficiently discharged from the rear end side of the penis fixing sheet 50B (exit side of the penis insertion portion 54B) depending on the urine force during urination. . Therefore, urine may overflow from the front end side of the penis fixing sheet 50B (the entrance side of the penis insertion portion 54B). If it exceeds 80%, the width W2 is too wide, and urine may not be sufficiently converged on the rear end side of the penis fixing sheet 50B (exit side of the penis insertion portion 54B). In addition, when adopting a configuration that forms a high absorption portion having high absorption performance at the center in the width direction of the absorber as described later, the high absorption portion cannot be efficiently arranged narrowly, There is a possibility that the effect cannot be exhibited sufficiently.

  As long as the width of the penis insertion part at the rearmost end of the plurality of penis fixation sheets is narrower than the width of the penis insertion part at the foremost end of the plurality of penis fixation sheets, especially for the aspect of the change of the width of the penis insertion part There is no limit. For example, the width of the penis insertion part is kept constant from the front end to the middle of the plurality of penis fixing sheets, and the width is continuously narrowed from the middle to the minimum width at the end of the plurality of penis fixing sheets. You may comprise so that it may reach. However, the width of the penis insertion portion 54B in the absorbent article 1B shown in FIG. 2A gradually decreases from the width W1 at the foremost end of the plurality of penis fixing sheets 50B, and the end of the plurality of penis fixing sheets 50B from the middle. It is configured to maintain a constant width W2 until it reaches the end.

[2-3] Absorber:
Hereinafter, the structure peculiar to the absorbent article of this invention is demonstrated among the structures of an absorber. The general configuration of the absorber will be described in another section.

  The absorbent article of the present invention absorbs the absorbent body from the portion located in the lower part of the penis fixing sheet at the center in the width direction, toward the rear end of the absorbent body, as compared with the other parts of the absorbent body. It is preferable that a high absorption part with high performance is formed. According to such a configuration, even when a large amount of urine is converged at the center in the width direction of the absorbent article, the urine can be sufficiently absorbed by the absorber. Therefore, it is possible to effectively prevent a situation where leakage of urine is not in time and leakage occurs. Although it is conceivable that the absorption performance of the entire absorber is high, it is possible to efficiently use SAP or the like if the high absorption section is formed only in the urine converging section that requires high absorption performance. This is advantageous in terms of production cost.

  Referring to FIG. 2A, the high absorption part is formed from the part located in the lower part of the penis fixing sheet 50 </ b> B toward the rear end of the absorber 22 in the center part in the width direction of the absorber 22. In particular, the width of the high absorption portion is in the range of 50 to 150% of the width W2 on the outlet side of the penis insertion portion 54B, and is directly below the front end of the penis fixing sheet 50B of the absorber 22 (inlet of the penis insertion portion 54B). It is preferable that a portion that is 50% of the entire length of the absorbent body 22 is formed starting from the portion that is positioned.

  If the width of the high absorption portion is less than 50% of the width W2 on the outlet side of the penis insertion portion, the concentrated large amount of urine cannot be sufficiently absorbed by the high absorption portion, and the advantage of forming the high absorption portion is enjoyed. It may not be possible. On the other hand, when the width of the high absorption part exceeds 150% of the width W2 on the outlet side of the penis insertion part, the width of the high absorption part is too wide with respect to urine converged at the center in the width direction of the absorbent article, The extra high absorption part increases and is inefficient.

  Even if the high absorption part is formed from the front end of the penis fixed sheet (entrance of the penis insertion part) to the front end side of the absorber or the part exceeding 50% of the total length of the absorber, urine is in contact with that part It is less efficient and inefficient.

  The high absorption part can be formed, for example, by locally increasing the amount of SAP contained in the absorber. As a method of locally increasing the amount of SAP, for example, a method of increasing the amount of SAP in a region by dispersing SAP only in a narrow region centered on the center line in the width direction of the absorber. In addition, a method such as disposing a highly absorbent sheet such as an SAP sheet on which SAP is preliminarily supported at a high density in a region where the SAP amount is desired to be increased can be exemplified.

  The absorbent article of the present invention accommodates the penis in a portion located in the center in the width direction of the absorbent body 22 and below the penis fixing sheet 50B, like the absorbent article 1B shown in FIGS. 2A to 2C. What formed the recessed part 64 for use is preferable. In such a configuration, the penis is likely to be accommodated in the penis accommodating recess 64 and the penis is fixed downward (inseam, rear end side of the absorbent article) as compared with the case where no recess is formed. Therefore, it is preferable in that the side leakage from the side edges E3 and E4 of the absorbent article 1B can be effectively prevented.

  In this case, the penis accommodating recess may be formed so as to protrude from the portion corresponding to the foremost end of the penis fixing sheet to the front end side of the absorber. Compared with the form in which the concave part for penis accommodation is formed only in the lower part of the penis fixing sheet, such a form is downward when the penis is inserted from the foremost end of the penis fixing sheet (the crotch side of the absorbent article 1B, The penis fixed to the rear end side) is hardly pressed by the penis fixing sheet 50B. Therefore, it is preferable in that it is easy to maintain a state in which the penis is fixed downward.

  The depth of the penis accommodating recess 64 is not particularly limited, but is preferably 20 to 75% deep with respect to the total thickness of the absorber 22. If it is less than 20%, since the concave portion is too shallow, the penis is likely to be pressed by the penis fixing sheet, and it may be difficult to keep the penis fixed downward. If it exceeds 75%, the absorbent body immediately below the penis accommodating recess 64 becomes too thin, so that the absorption performance at that portion is lowered, and skin trouble such as rash on the penis may occur due to unabsorbed urine. More specifically, since the general thickness of the absorber 22 is about 4 to 20 mm, it is preferable that the depth of the penis accommodating recess 64 is 1 to 15 mm.

  The width of the penis-accommodating recess 64 may be a constant width from the front end to the rear end, but the width of the front end of the penis-accommodating recess 64 as in the absorbent article 1B shown in FIGS. 2A to 2C. It is preferable that the width W4 of the rear end of the penis accommodating recess 64 is narrower than W3. According to this structure, compared with the form which made the width | variety of the recessed part 64 for penis accommodation constant, the excreted urine tends to converge on the center part of the width direction of the absorbent article 1B, and the absorbent article 1B Even when the mounting position of is slightly shifted from side to side, it is preferable in that the penis is easy to fit in the penis accommodating recess 64.

  The degree of narrowing of the width W4 of the rear end of the penis accommodating recess 64 with respect to the width W3 of the front end of the penis receiving recess 64 is not particularly limited. However, it is preferable that the width W4 is 70% or less of the width W3. If it exceeds 70%, the reduction rate from the width W3 to the width W4 becomes small, and the effect of converging the excreted urine to the central portion in the width direction of the absorbent article 1B may be insufficient.

  The absorbent article of the present invention is not particularly limited with respect to the shape of the absorbent body. For example, what was formed in the substantially rectangular shape like the absorber 22 shown to FIG. 1A can be illustrated. Moreover, like the absorber 22 shown to FIG. 1A, the rectangular corner | angular part may be R-cut and it may be comprised by the curve shape.

  However, in the absorbent article of the present invention, as in the absorbent article 1B shown in FIG. 2A, the absorbent body 22 has the penis fixing sheet 50B disposed more than the width of the front end of the absorbent body 22 and the rear end of the absorbent body 22. It is preferable that the width of the portion is widened.

  The shape as described above is less likely to cause side leakage, and moreover, the wearing position of the absorbent article 1B is difficult to shift, so that the wearing feeling is excellent. Specifically, by configuring the front end side of the absorbent body 22 to be narrow, the absorbent article 1B can also be configured to have a narrow front end E1. In such a form, the wearer's abdomen is not excessively covered by the front body 2 of the absorbent article 1B, and the feeling of wear is improved. When the absorbent article is a urine pad, if the front end side of the urine pad is unnecessarily large, corners on the pad front end side often break when worn. In such a case, there is a possibility that urine leakage may occur from a portion where the urine pad is broken, or that portion may hit the wearer's skin and the feeling of wear may be reduced. If the front end of the absorbent body 22, and thus the front end E <b> 1 of the absorbent article 1 </ b> B, is configured to be narrow, such a problem is unlikely to occur.

  Furthermore, when the absorbent article 1B is a urine pad, the absorbent article 1B can be configured to be narrow on the rear end E2 side by configuring the rear end side of the absorbent body 22 to be narrow. In such a form, the width | variety of the crotch part 4 and the back body 6 of the absorbent article 1B inserted in a wearer's crotch can be comprised narrowly. Therefore, both side edges of the crotch part 4 and the back body 6 of the absorbent article 1B are less likely to hit the wearer's inner thigh, and the wearing feeling is improved. Furthermore, by configuring the width of the portion where the penis fixing sheet 50B of the absorbent body 22 is widened, the absorbent article on the abdomen side having a planar shape compared to the back side where the narrow crotch and groin are present. Since 1B can be made to contact widely, even if a wearer moves, there exists an effect that the mounting position of the absorbent article 1B is hard to shift | deviate.

  Considering the above effects, the width of the absorber 22 front end and the width of the rear end are both 40 to 80% of the width of the portion of the absorber 22 where the penis fixing sheet 50B is disposed. Is preferred.

  In addition, when the absorber 22 is configured so that the width of the portion where the penis fixing sheet 50B is arranged is wider than the width of the front end of the absorber 22 and the rear end of the absorber 22, the width of the front end of the absorber 22 and the absorber It is preferable that the width of the rear end of 22 be the same width in that the production speed when continuously producing the absorbent article 1B can be increased.

  In addition, like the absorbent article 1B shown in FIG. 2A, not only the part where the penis fixing sheet 50B of the absorbent body 22 is disposed, but also the part on the rear end E2 side of the absorbent article 1B from the part is continuously wider. It is preferable to configure. In such a configuration, only the portion of the absorbent body 22 where the penis fixing sheet 50B is disposed is configured to be wide, and the region on the rear end side of the absorbent body 22 is configured to be narrower than that of the first joint. It is preferable in that the urine converged on the central portion in the width direction of the absorbent article 1B by the portion 52C and the second joint portion 52D can be sufficiently absorbed by the wide absorbent body 22 and can hardly cause leakage.

[3] Other components of the absorbent article:
The absorbent article of the present invention is arranged such that the absorbent body 22 and at least a part thereof are made of a liquid-permeable material and cover the surface of the absorbent body 22 as in the absorbent article 1A shown in FIGS. 1A to 1C. The top sheet 18 is made of a liquid-impermeable material, and the back sheet 20 is disposed so as to cover the back surface of the absorber 22.

[3-1] Absorber:
The “absorber” is a member for absorbing and holding the wearer's urine and the like, and is made of an absorbent material. Usually, the absorber is sandwiched between a top sheet and a back sheet, and used in a state of being integrated with both sheets.

  Examples of the “absorbent material” include fluff pulp, super absorbent polymer (hereinafter referred to as “SAP”), a hydrophilic sheet, and the like. “Fluff pulp” is made by pulverizing wood pulp or non-wood pulp into cotton, “SAP” is sodium polyacrylate, “Hydrophilic sheet” is tissue, absorbent paper, hydrophilized It is preferable to use a non-woven fabric that has been treated.

  As the absorber, it is preferable to use one or two or more absorbent materials formed into a single-layer or multi-layer mat. Especially, what combined 10-500 mass parts SAP with respect to 100 mass parts of fluff pulp is preferable. At this time, the SAP may be mixed in the fluff pulp mat or used in a layered manner between the fluff pulp mats.

[3-2] Top sheet:
Since the top sheet needs to allow the wearer's urine or the like to pass therethrough, at least a part (all or a part) of the top sheet is made of a liquid-permeable material.

  Examples of the “liquid permeable material” include woven fabric, non-woven fabric, and porous film. Among these, it is preferable to use a nonwoven fabric made of a thermoplastic resin such as polypropylene, polyethylene, polyester, aliphatic polyamide, etc., which has been subjected to a hydrophilic treatment.

  As the “nonwoven fabric”, a nonwoven fabric produced by a production method such as air through (card hot air) or card embossing can be suitably used. The “hydrophilic treatment” can be performed by applying, spraying, impregnating, etc. a surfactant.

  The top sheet is preferably “at least partly”, more specifically, when the top sheet is viewed in plan, at least the vicinity of the surface of the absorber is made of a liquid-permeable material.

[3-3] Backsheet:
The back sheet is a sheet disposed so as to cover the back surface of the absorbent body (the surface located on the side far from the wearer's skin when the urine pad is attached). The back sheet is made of a liquid-impermeable material because it is necessary to prevent the wearer's urine from leaking outside the urine pad.

  There is no restriction | limiting in particular about the arrangement position of a back seat | sheet. From the viewpoint of preventing leakage of urine absorbed by the absorber, it is preferable that a back sheet is disposed at least in a portion where the absorber exists.

  Examples of the liquid-impermeable material constituting the backsheet include a liquid-impermeable film made of a resin such as polyethylene. Among these, a microporous polyethylene film is preferably used. This microporous polyethylene film has a large number of fine pores of 0.1 to several μm, and is liquid impervious but has moisture permeability, so that the inside of the diaper can be prevented from being steamed There is.

  A cover sheet may be bonded to the outer surface side of the back sheet. This cover sheet is used to reinforce the back sheet and improve the feel (tactile feeling) of the back sheet.

  Examples of the material constituting the cover sheet include woven fabric and non-woven fabric. Especially, it is preferable to use the dry nonwoven fabric and wet nonwoven fabric which consist of thermoplastic resins, such as polyethylene, a polypropylene, and polyester.

[3-4] Solid gathering:
The absorbent article of the present invention includes at least a pair of three-dimensional gathers 26 (26a, 26b) which are made of a water-repellent sheet 32 and disposed on both sides of the absorbent body 22 as in the absorbent article 1C shown in FIGS. 3A and 3B. It is preferable to provide.

  The structure used for the conventional disposable diaper and a urine pad can be employ | adopted for the structure of a three-dimensional gather. For example, a material in which a stretchable material (solid gather stretchable material 36) is sandwiched and fixed between layers of the water-repellent sheet 32, and a gather (claw) is formed by the contraction force of the solid gather stretchable material 36 can be suitably used. . The water-repellent sheet may be a nonwoven fabric produced by a production method such as card embossing or spunbonding, but a nonwoven fabric sheet such as SMS or SMMS having a high waterproof property is more preferable.

  The three-dimensional gather may be separately provided with a water-repellent sheet for three-dimensional gather, or may be formed by a part of a sheet material (for example, a back sheet) constituting the urine pad.

[3-5] Various elastic materials:
In the absorbent article of the present invention, various elastic materials may be arranged in order to improve the fit to the wearer's skin.

  For example, when the absorbent article is a urine pad as in the absorbent article 1A shown in FIGS. 1A to 1C, the side edge stretchable material 48 may be disposed on both side edges or the like. By disposing this stretchable material, it is possible to form a gather that is rich in stretchability at both side edges of the urine pad. Therefore, it becomes difficult to form a gap at both side edges of the urine pad, and so-called side leakage can be effectively prevented.

  Moreover, when the absorbent article of this invention is a disposable diaper, it is preferable to arrange | position an elastic material around a leg and arrange an elastic material around a waist.

  By arranging the leg circumference stretchable material along the leg circumference opening, it is possible to form a gather (leg gather) rich in elasticity in the leg circumference opening. Further, by arranging a waist elastic material along the waist opening, a gather (waist gather) rich in elasticity can be formed in the waist opening. Furthermore, in a pants-type disposable diaper, a belly stretchable material is disposed in a portion between the waist opening and the leg opening (that is, a portion corresponding to the wearer's abdomen), whereby the belly of the wearer is disposed. Tammy gathers that are rich in elasticity can be formed around them.

  For example, the absorbent article 1C shown in FIGS. 3A to 3D is a pants-type disposable diaper, and is composed of two water-repellent nonwoven sheets (an inner sheet 16a and an outer sheet 16b) to form an exterior sheet 16. This is an example in which various elastic materials are sandwiched and fixed between layers of the inner sheet 16a and the outer sheet 16b. In this example, the leg-surrounding elastic member 40 is arranged in a curve along the curve of the leg-periphery opening 12, and a plurality of waist-surrounding elastic members 42 are provided along the opening end of the diaper waist-periphery opening 10. A plurality of elastic materials around the abdomen so as to surround the circumference of the wearer's abdomen in the portion between the waist circumference opening 10 and the leg circumference opening 12 (that is, the portion corresponding to the circumference of the wearer's abdomen) 44 is arranged.

  Regarding the stretchable material, the constituent material, the elongation rate of the material, the stretched state at the time of fixing, and the like may be determined in consideration of the degree of gather contraction and the like.

  As an elastic material, the elastic material used with the conventional disposable diaper and the urine pad can be used suitably. Specific examples include elastic rubber, elastic film, elastic foam (urethane foam, etc.), etc. in addition to natural rubber flat rubber and synthetic rubber (urethane rubber, etc.) elastic thread. it can.

  The stretchable material is preferably fixed in the stretched state in order to exert a sufficient stretch force. For example, when the elastic material is a flat rubber made of natural rubber or a thread rubber made of an elastic thread of synthetic rubber, it is preferably fixed in an extended state of 120 to 400%, and fixed in an extended state of 200 to 300%. More preferably. By fixing in the extended state in such a range, it is possible to apply a sufficient expansion / contraction force without applying an excessive tightening force to the wearer.

  The stretchable material as described above is fixed to other constituent members of the absorbent article by an adhesive or other means. The fixing method may be, for example, adhesion using a hot melt adhesive or other highly fluid adhesive, or may be welding by heat such as heat sealing or ultrasonic waves.

[4] Application target:
The absorbent article of the present invention includes a urine pad such as the absorbent article 1A shown in FIGS. 1A to 1D, a pants-type disposable diaper such as the absorbent article 1C shown in FIGS. 3A to 3D, and a tape type. It can also be applied to disposable diapers. That is, in the tape-type disposable diaper, the effect of the present invention can be enjoyed by attaching a plurality of penis fixing sheets to the top sheet.

  A “tape-type disposable diaper” includes an absorbent body, a top sheet, and a back sheet, and is arranged to extend from the left and right side edges of the back body, and fixes the front and back bodies. The disposable diaper further provided with the fastening tape for. As a fastening member of the fastening tape, a mechanical fastener (planar fastener) or the like is used in addition to the adhesive fastener.

  The absorbent article of the present invention will be described more specifically with reference to the drawings. However, the absorbent article of the present invention encompasses all absorbent articles having the invention-specific matters, and is not limited to the following examples.

[Example 1]
As the urine pad of Example 1, an absorbent article 1A shown in FIGS. 1A to 1D was produced. This absorbent article 1A is an adult urine pad, and has a substantially rectangular shape with a length of 490 mm and a width of 210 mm. An absorber having a thickness of 4 mm was used.

  50 A of penis fixed sheets were attached to the absorbent article 1A. The penis fixing sheet 50A was constituted by a water-repellent nonwoven sheet. The size was a rectangular shape with a width of 130 mm and a length of 50 mm. Moreover, 50 A of penis fixed sheets were arrange | positioned so that the forefront end of 50 A of penis fixed sheets may be located in the position 60 mm away from the front end E1 of 1 A of absorbent articles. In addition, 50 A of penis fixing sheets were arrange | positioned at the upper part of the absorber 22 arrangement | positioning site | part of 1 A of absorbent articles.

  The penis fixed sheet 50A was joined to the surface of the top sheet 18 by hot melt adhesive at both side edges. At this time, each penis fixing sheet 50A was repeatedly arranged in such a manner that the front end portion and the rear end portion overlapped with the adjacent penis fixing sheet 50A by a length of 10 mm, thereby arranging four penis fixing sheets 50A. .

  Further, as shown in FIGS. 1C and 1D, the four penis fixing sheets 50A include other penis fixing sheets whose rear ends are adjacent to the upper side of the rear end of one penis fixing sheet 50A that is adjacent to the front ends. The structure to be arranged so as to be located below the front end portion of the sheet 50A was repeatedly arranged.

  In addition, 52 A of 1st junction parts and the 2nd junction part 52B each formed in the strip | belt shape of width 10mm. At this time, the penis insertion part 54A formed between the first joint part 52A and the second joint part 52B was formed to have a width of 100 mm.

[Example 2]
As the urine pad of Example 2, an absorbent article 1B shown in FIGS. 2A to 2D was produced. This absorbent article 1B is a urine pad for adults, and is 490 mm in length, 290 mm in width where the penis fixing sheet 50B is disposed, 210 mm in width at the front end E1, and 210 mm in width at the rear end E2. did. An absorber having a thickness of 4 mm was used.

  A penis fixing sheet 50B was attached to the absorbent article 1B. The penis fixing sheet 50B was composed of a water-repellent nonwoven sheet. The size is based on a rectangular shape having a width of 200 mm and a length of 70 mm, and the center in the width direction at the rear end of the penis fixing sheet 50B is cut out in an arc shape toward the front end of the penis fixing sheet 50B. It was. The length of the central part in the width direction of the penis fixing sheet 50B was 30 mm.

  Moreover, the penis fixed sheet 50B was disposed on the center line in the width direction of the absorbent article 1B so that the distance between the front end of the absorbent body 22 and the front end of the penis fixed sheet 50B was 3 cm apart.

  The penis fixed sheet 50B was joined to the surface of the top sheet 18 by hot melt adhesive at both side edges. At this time, the structure in which the front end portion and the rear end portion of the penis fixing sheet 50B are arranged so as to overlap with the adjacent penis fixing sheet 50B by a length of 30 mm was repeated to arrange four penis fixing sheets 50B.

  As shown in FIGS. 2A and 2D, the four penis fixing sheets 50 </ b> B have other penis fixings whose rear end is adjacent to the upper side of the rear end of one penis fixing sheet 50 </ b> B whose front end is adjacent. The structure to be arranged so as to be located below the front end portion of the sheet 50B was repeatedly arranged.
