Description

The present invention relates to an absorbent article such as a pad type or a taped type, which includes an outer sheet, an inner sheet, and an absorbent body sandwiched therebetween, and is used in combination with an outer such as a pants-type diaper.

There are various forms of absorbent articles such as disposable diapers according to the age, sex, and application of the user. For example, a pad-type absorbent article (paper diaper) is used with an outer such as a pants-type paper diaper, a diaper cover, and cloth underwear. That is, the pad-type absorbent article is used by being inserted inside the outerwear worn by the user, and after the use, only the absorbent article is discarded, and as a simple absorbent article, an absorbent article especially for adults. Widely used as.
This pad-type absorbent article includes an exterior sheet (back sheet), an inner sheet (top sheet), and an absorbent body sandwiched therebetween, and is worn from the ventral side to the dorsal side so as to cover the crotch of the user. The outer shapes of the absorbent article and the absorbent body are vertically long.
In addition, a tape stopper having the same structure as the pad-type absorbent article, with tape members (fastening tapes) provided on both sides of the back side and fastening members (front sheet) provided on both sides of the abdominal side Type absorbent articles are widely used, as are pad type absorbent articles.
Unlike the pad-type absorbent article, this tape-fixed type absorbent article is used alone or in combination with the pad. At the time of use, the abdomen, crotch and back of the absorbent article are used. The parts are applied to the user's abdominal side, crotch side and dorsal side, and the back side tape member (fastening tape) is engaged with the abdominal side fastening member (front seat) to be mounted on the user.
Then, when the absorbent article such as the pad type or the taped type is attached, it is necessary to apply it to the user so that the left and right parts of the absorbent article are even, and therefore, the central position of the absorbent article and the user. For alignment, the exterior sheet has a center line such as a straight line, a dot arranged in a straight line, or the like along a center line extending in the longitudinal direction of the exterior sheet (a center line that bisects the lateral direction of the exterior sheet). In many cases, a display similar to that (hereinafter referred to as "center line display") is provided.

For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2004-298571), in a back sheet (exterior sheet), as a front and back discriminating means, a linear thick line is formed near a center line extending in the longitudinal direction (center position in the width direction). Although an absorbent article on which a design pattern or the like is printed is disclosed, the thick linear design pattern or the like also functions for center alignment between the absorbent article and the user.
When the centerline is displayed on the exterior sheet, it is desirable to provide the centerline at the center of the exterior sheet in the longitudinal direction. However, when manufacturing the absorbent article, the meandering or printing of the material such as the base sheet is performed. The center line may be displayed at a position slightly deviated from the center of the exterior sheet due to the positional deviation of the.
FIG. 26 is a front view of a state in which the above-mentioned pad-type absorbent article is expanded and made planar, in which 100 is an absorbent article, 101 is an exterior sheet (backsheet), and 102 is an absorber. , 103 is a center line display, and C100 is a center line extending in the longitudinal direction.
As shown in FIG. 26, in the absorbent article 100, both of the exterior sheet 101 (including the inner sheet attached to the exterior sheet) and the absorbent body 102 are bulged in the upper and lower parts in the longitudinal direction and left and right in the central part in the same direction. The dent and the lower part in the same direction have a shape that swells to the left and right, and the lateral width (width in the left-right direction) becomes wider in the order of the central part, the upper part, and the lower part, and shifts slightly to the right from the centerline C100 of the exterior sheet 100. A center line display 103 is provided at the open position.
In this case, the upper part is the ventral or dorsal part, the central part is the crotch part, and the lower part is the dorsal part or the ventral part, but the upper part whose lateral width (area) is narrower than the lower part is the ventral part. Whether it is the back side or the back side depends on the user. For example, a female user often has the upper part as the ventral side, and a male user often has the upper part as the back side.

The absorbent article 100 is usually transported and stored in a folded state for the sake of space saving, convenience of handling, and the like.
27: is explanatory drawing explaining the state which folds the absorbent article 100 shown in FIG. 26, (a) of this figure is a front view of the absorbent article 100 before folding, (b) of FIG. The front view of the absorbent article 100, the figure (c) is a front view of the absorbent article 100 after folding, and in the figure, f10 to f12 are folding lines.
First, in the absorbent article 100 in the unfolded state as shown in FIG. 27A, the left side portion and the right side portion are folded inward along the longitudinal folding lines f10 and f11. As shown in (b), it is folded in three.
Next, the absorbent article 100 folded in three is folded inward along the folding line f12 in the direction perpendicular to the longitudinal direction, and is folded in six as shown in FIG.
In this case, as shown in FIG. 24( a ), the centerline display 103 is provided at a position slightly shifted to the right from the centerline C100 of the exterior sheet 101, and the absorbent article 100 and the user's center position are slightly displaced and absorbed. Even if the absorbent article 100 is attached, there is no problem in using the absorbent article 100.
However, when the user (including the wearer who wears the absorbent article on the user) notices that the centerline display 103 is provided at a position deviated from the centerline C100 of the exterior sheet 101, the user may May have a bad impression as if the absorbent article 100 is defective or poor.
Since the manufacturer/seller of the absorbent article refrains from shipping products that may give a bad impression to the user, the absorbent article 100 in which the centerline display 103 is slightly deviated from the centerline C100 is manufactured. The problem arises that it must be discarded.
In particular, in the absorbent article 100 that is folded and made smaller as shown in FIGS. 27B and 27C, the deviation between the center line C100 of the exterior sheet 101 and the center line display 103 is conspicuous, and the above-mentioned problem becomes remarkable. Become.
The above points also apply to the tape-fixed type absorbent article.

Fig. 28 is a side view of the folded absorbent article 100 shown in Fig. 27(c), the same figure (a) is a side view of one folded absorbent article 100, and the same figure (b) is. The side view of the state which piled up a plurality of folded absorbent articles 100 is shown, and in the figure, 104 (104a, 104b) is a side surface.
As shown in FIG. 28( b ), the absorbent article 100 is stored in a state in which a plurality of the absorbent articles 100 are stacked with the side surface 104 facing the front of the user. This point is the same in the tape-fixed type absorbent article.
By the way, since there are different types of absorbent articles 100 having the same outer shape, such as different absorption amounts of the absorbent body 102, the absorbent article 100 can be used to identify what kind of absorbent article 100 it is. Display is required. This point is the same in the tape-fixed type absorbent article.
For example, in Patent Document 2 (Japanese Patent Laid-Open No. 2008-264232), in order to make it possible to identify the absorbing ability of the absorbent article even after the absorbent article is taken out of the package, the back sheet absorbs the absorbent body. Disclosed is an absorbent article in which an information display section as an identification section capable of identifying an ability is printed and displayed at six places in accordance with each corner and center.
However, in the absorbent article of Patent Document 2, the information display portion is printed and displayed on the back sheet in the unfolded state as shown in FIG. 24, and a plurality of sheets are folded as shown in FIG. 28(b). There is a problem that the information display unit of Patent Document 2 does not function as an identification display for the absorbent articles stored in a stacked state.
In addition, the absorbent article of Patent Document 2 does not have a center line display, and when the information display unit of Patent Document 2 is provided in an absorbent article that requires a center line display, the information display provided at the center of the back sheet The part overlaps with the center line display, and the center line display becomes difficult to see, resulting in a problem that the function is impaired.
Further, FIG. 4 of Patent Document 2 shows a tape-fastened type absorbent article in which a central portion of a back sheet is provided with four information display portions along the longitudinal direction thereof. The information display portion provided in does not form a straight line along the center line in the longitudinal direction and does not function as a center line display.
In this regard, Patent Document 3 (Japanese Patent Laid-Open No. 2005-177160) discloses an absorbent article in a folded state by forming a plurality of rows of marks in a direction oblique to the longitudinal direction on the entire surface of the backsheet. Disclosed is an absorbent article in which the mark appears on the front surface or the side surface and the type of the absorbent article can be identified by whether the mark is a continuous line or a discontinuous line.
However, in a pad-type or tape-fixing type absorbent article in which a center line is displayed along the center line in the longitudinal direction, the mark of Patent Document 3 is the center line display 103 shown in FIGS. 26 and 27. There is a problem that the center line display 103 becomes difficult to see due to the overlapping, the function thereof is impaired, and it becomes difficult to align the absorbent article 100 and the user.

[Basic structure of pad-type absorbent article]
An embodiment in which the present invention is applied to a pad type absorbent article will be described. First, the basic configuration of the pad type absorbent article will be described.
FIG. 1 is a front view of a pad type absorbent article to which the present invention is applied in a state of being expanded and planarized, FIG. 2 is a rear view of the absorbent article of FIG. 1, and FIG. 3 is YY of FIG. FIG. 4 is a sectional view, and FIG. 4 is a sectional view taken along line XX in FIG.
In the figure, 1 is a pad type absorbent article, 2 is an absorber, 3 is an exterior sheet, 3a is a polyethylene film, 3b is a non-woven fabric, 4 is an inner sheet, 5 and 6 are three-dimensional gather sheets, and 5a and 6a are standing portions. 5b and 6b are leading edges, 5c and 6c are folded portions, CL is a center line extending in the longitudinal direction, SF is a side flap, D1 and D2 are elastic members, and the absorbent article 1 has a longitudinal direction (lateral direction). Direction) and the longitudinal direction (longitudinal direction) as the Y direction.
As shown in the figure, the absorbent article 1 includes an absorber 2, an exterior sheet 3 that covers the absorber 2 from the front side, an inner sheet 4 that covers the absorber 2 from the back side, and a three-dimensional gather sheet 5 that is overlaid on the inner sheet 4. , 6 are included.
The absorbent body 2 is mainly composed of cotton-like pulp containing superabsorbent polymer particles and is combined with absorbent paper or the like (not shown), and absorbs and retains body fluids discharged by the user.
The exterior sheet 3, which is also called a back sheet, is a laminate of a liquid-impervious polyethylene film 3a and a nonwoven fabric 3b as shown in FIGS. 3 and 4. The non-woven fabric 3b is laminated in order to improve the appearance and the feel of the skin, and the exterior sheet 3 may be composed of only the polyethylene film 3b.
Although not shown in the figure showing the absorbent article 1, a locking means such as an adhesive material or a hook material is usually used as a means for fixing the absorbent article to the outer body or body such as used in a paper diaper. The outer sheet 3 may be provided with the sheet 3 or a belt-shaped or tab-shaped fixing means.
The inner sheet 4 is also called a top sheet and is made of a non-woven fabric.
The exterior sheet 3 and the inner surface sheet 4 overlap each other outside the peripheral edge of the absorber 2 and are bonded to each other by an adhesive (not shown) or heat fusion at the overlapping portion, whereby the absorber 2 is enclosed. ..

The three-dimensional gather sheets 5 and 6 are made of a non-woven fabric, and are bonded to the exterior sheet 3 with an adhesive (not shown) except for the standing portions 5a and 6a as shown in FIG. The standing portions 5a and 6a are folded back at their tips to form folded portions 5b and 6b, and elastic members D1 and D2 such as rubber threads are sandwiched between the folded portions 5b and 6b so that the folded portions 5b and 6b overlap each other. The surfaces are bonded by an adhesive (not shown) or heat fusion.
FIG. 5 is a cross-sectional view taken along the line XX in a state where the upright portions 5a and 6a are upright to form a three-dimensional gather.
As shown in FIG. 2, since the elastic members D1 and D2 are arranged along the longitudinal direction of the absorbent article 1 and are adhesively fixed to the folded-back portions 5b and 6b in an expanded state, the elastic members D1 and D2 contract. As a result, the entire absorbent article 1 is curved so that the exterior sheet 3 side is convex in the longitudinal direction, and as a result, as shown in FIG. 5, the leading edges 5b and 6b are separated from the inner surface sheet and the upright portions 5a and 6a are formed. It stands up in a V shape and forms an arch-shaped three-dimensional gather. By forming the three-dimensional gathers in this way, lateral leakage of body fluids and the like is prevented.
The side flap SF is a flap-shaped portion in which the exterior sheet 3 and the inner sheet 4 are bonded together, and is formed outside the peripheral edge of the absorber 2.
Although the elastic members D1 and D2 are arranged one by one, a plurality of elastic members may be arranged, and the three-dimensional gather sheets 5 and 6 may have a configuration different from the above. The three-dimensional gather sheets 5 and 6 may not be provided.

[Outline of absorbent article 1 and absorbent body 2]
The outer shape of the absorbent article 1 and the outer shape of the absorbent body 2 are similar to each other as shown in FIG. 1, and both have a vertically long shape in the Y direction (longitudinal direction), and the width (horizontal width) in the X direction (horizontal direction) is Is changing.
The outer shape of the absorbent body 2 of the absorbent article 1 bulges in the X direction at the upper and lower portions in the Y direction (hereinafter simply referred to as “upper portion” and “lower portion”), and the central portion in the Y direction (hereinafter simply referred to as “central portion”). The outer shapes of the absorbent article 1 and the absorbent body 2 are dented in the X direction, the lateral width of the lower portion is wider than the lateral width of the upper portion, and the area of the lower portion is also wider than the area of the upper portion.
That is, both the absorbent article 1 and the absorbent body 2 have a wider width and a larger area in the order of the central portion, the upper portion, and the lower portion.
In this way, the lateral widths and areas of the outer shapes of the absorbent article 1 and the absorbent body 2 are changed because the absorbent article having a width and a length larger than the crotch portion is formed along the body. This is because the three-dimensional gathers are closely attached to the user's ventral side, crotch side and dorsal side (buttocks) to prevent leakage of body fluids discharged by the user and to reduce discomfort due to the rigidity of the absorber.
In this case, the central part is the crotch side part that is applied to the crotch part of the user.
In addition, it is not always constant whether the lower part, which is the larger bulge, is the ventral side applied to the user's ventral side or the dorsal side applied to the dorsal side (gluteus). It depends on the application.
For example, when the user is a woman, the lower part is often the dorsal part which is applied to the dorsal side (buttock), and when the user is a male, the lower part is often the ventral part which is applied to the ventral side. .. Further, when the user lays down on the bed, the lower part is laid under the back side (buttock), so that the lower part becomes the back side regardless of the sex of the user.
The shape (outer shape) of the pad-type absorbent article or the like to which the present invention is applied is not limited to the outer shape in which the upper portion and the lower portion are bulged in the X direction like the absorbent article 1 shown in FIG. 1. Alternatively, only one of the upper portion and the lower portion may bulge in the X direction, and the other may have the same lateral width as the central portion, or the lateral width may be constant. Similarly, with respect to the absorber, only one of the upper portion and the lower portion may bulge in the X direction, and the other may have the same lateral width as the central portion, or may have a constant lateral width.

[Function 2 of discrimination display]
Next, in the fourth figures 90a and 90b forming the discrimination displays 91A to 91D, the vertices of the two triangles forming the fourth figure 90a are located on the outer edge side on the left side of the absorbent article 1, and the fourth figure is formed. The vertices of the two triangles forming 90b are located on the right outer edge side of the absorbent article 1.
Therefore, the fourth graphic 90a functions as a leftward arrow, and the discrimination displays 91A and 91C formed by the fourth graphic 90a face the portions (regions R1 and R3) provided with the discrimination display to the left. Suggest that.
Further, the fourth graphic 90b functions as an arrow pointing to the right, and in the discrimination displays 91B and 91D formed by the fourth graphic 90b, the portions (regions R2, R4) provided with this discrimination display are directed to the right. Suggest.
That is, the discrimination display 91A suggests expanding the left side portion (region R1) of the upper portion where the discrimination display is provided to the left, and the discrimination display 91B indicates the right side portion (region of the upper portion where the discrimination display is provided. R2) is suggested to be widened to the right, and the discrimination display 91C suggests that the lower left portion (region R3) provided with this discrimination display is to be spread to the left, and the discrimination display 91D is shown to be this discrimination display. It is suggested that the lower right side portion (region R4) provided with is widened to the right.
Thereby, the discrimination displays 91A to 91D are functions (function 2) that make the wearer aware that when the absorbent article 1 is applied to the user, the left side part and the right side part are spread in the left-right direction to apply to the user. Fulfill.

The function 2 of the discrimination displays 91A to 91D is further strengthened by adding characters to the discrimination displays 91A to 91D.
FIG. 25 is an explanatory diagram showing an example of the discrimination displays 91A to 91D to which characters are added, and w1 and w2 are characters in the figure.
As shown in FIG. 25, in the discrimination display 91A, the character w1 described as “open” is added to the fourth figure 90a in the middle row from top to bottom (FIG. 25A), and in the discrimination display 91B, the middle row. To the fourth figure 90b of the above, the character w2 described as "Open" is added from the bottom to the top ((b) of the same figure). Is added ((c) in the figure), and the character w2 is added to the fourth graphic 90b in the upper, middle, and lower rows in the discrimination display 9D ((d) in the figure).
As described above, by adding the characters w1 and w2 that mean "to open" to the discrimination displays 91A to 91D, the left side part and the right side part are spread in the left-right direction and the absorbent article 1 is applied to the user. It can make people strongly aware.
Note that the characters added to the discrimination displays 51A to 51D are not limited to the characters w1 and w2 described as "open", but may be "expand", "expand", "pull", or the like in the X direction (left-right direction). ) Is a character that means to spread.

[Function 3 of discrimination display]
The discrimination displays 91A, 91B provided on the upper part of the absorbent article 1 are composed of three fourth figures 90a, 90b, and the discrimination displays 91C, 91D provided on the lower part of the absorbent article 1 are five. It is composed of the fourth figures 90a and 90b.
Since the distances between the fourth figures 90a and 90b constituting the discrimination displays 91A to 91D are the same, the distance between the uppermost fourth figure 90a and the lowermost fourth figure 90a in the discrimination display 91C is the discrimination display 91A. Is longer than the distance between the uppermost fourth figure 90a and the lowermost fourth figure 90a, and the distance between the uppermost fourth figure 90b and the lowermost fourth figure 90b in the discrimination display 91D is the uppermost in the discrimination display 91B. This is longer than the distance between the fourth figure 90b and the fourth figure 90b at the bottom.
Therefore, for the wearer, the lower part where the five fourth figures 90a and 90b are arranged is longer in the Y direction (longitudinal direction) than the upper part where the three fourth figures 90a and 90b are arranged, and the lower part It is obvious that the area of is larger than the area of the upper part, and when the absorbent article 1 is worn by the user, the part where the upper part and the lower part are applied is not mistaken.
Further, for the wearer, the folded absorbent article 1 can be completely unfolded to check whether the upper part or the lower part is wider, or a mark provided in the center of the exterior sheet 3 (for example, the lower part is wider than the upper part). It is possible to discriminate which of the upper portion and the lower portion is wider by simply opening one of the folds and looking at the discrimination displays 91A to 91D without looking at the mark, etc. Can quickly determine the direction of application.
Thus, the discrimination displays 91A to 91D have a function (function 3) that makes it easy to distinguish which of the upper area and the lower area of the absorbent article 1 is larger.
In this case, the number of the fourth figures 90a and 90b arranged on the upper and lower parts is not limited to three and five shown in FIG. 22, but the fourth figures 90a arranged on the smaller area may be It suffices that the number of 90b is smaller than the number of the fourth figures 90a and 90b arranged in the larger area, but it is preferable that the number is different corresponding to the difference in area. For example, if the area of the lower part is twice the area of the upper part, the number of the fourth figures 90a and the like arranged on the lower side is preferably twice the number of the fourth figures 90a and the like arranged on the upper side. ..
