JP7512183B2 - Absorbent articles - Google Patents

Description

The present invention relates to absorbent articles such as panty liners, panty liners, and sanitary napkins.

Absorbent articles are constructed by disposing an absorbent body between a top sheet and a back sheet. Some absorbent articles have a deodorizing function (see, for example, Patent Document 1). It has also been proposed to color the components that make up absorbent articles in order to conceal stains caused by excreted body fluids.

JP 2020-69299 A

In absorbent articles with deodorizing functions, it is difficult to visually confirm that function, which can cause the wearer to feel uneasy. In addition, when the components that make up the absorbent article are colored to conceal bodily fluids, the color makes it impossible to visually confirm the presence of the absorbent body, which can cause the wearer to feel uneasy about the absorption performance.

The objective of the present invention is to provide an absorbent article that reminds the wearer of the deodorizing function of the absorbent article and gives a sense of security regarding its absorbency.

An absorbent article according to one aspect of the present invention comprises a top sheet, a back sheet, and an absorbent body.
The top sheet is positioned on the skin side.
The back sheet is positioned on the non-skin side.
The absorbent body is located between the top sheet and the back sheet.
The absorbent body contains a deodorant and has a purple color.
The skin side has a first colored region in which the purple color of the absorbent body is visible through the top sheet when the absorbent article is viewed in plan from the top sheet side.

As described above, the absorbent article of the present invention reminds the wearer of the deodorizing function of the absorbent article and gives them a sense of security regarding its absorbency.

1 is a plan view of an absorbent article according to one embodiment of the present invention, viewed from the top sheet side. 2 is a cross-sectional view taken along line II-II in FIG. 1. (A) is a plan view showing typically the colors visible when the absorbent article of Figure 1 is viewed from the top sheet side, and (B) is a plan view showing typically the colors visible when the absorbent article of Figure 1 is viewed from the back sheet side.

Below, an embodiment of the present invention will be described with reference to the drawings. Here, a panty liner will be taken as an example of an absorbent article. Panty liners are generally attached to the inside of the crotch area of underwear such as shorts during the period from the late menstrual period when the amount of menstrual blood is low until the non-menstrual period, and are used to absorb body fluids such as vaginal discharge, menstrual blood, or urine.

<Overall structure of panty liner>
1, a panty liner 1 as an absorbent article of the present invention has a vertical direction X corresponding to the front-to-back direction of a wearer, and a horizontal direction Y corresponding to the left-to-right direction of the wearer and perpendicular to the vertical direction X. The horizontal direction of the panty liner 1 corresponds to the width direction of the panty liner 1.
In this specification, with respect to the thickness direction Z of the panty liner 1, the side closer to the wearer's skin when worn may be referred to as the upper or skin side, and the side closer to the clothing may be referred to as the lower or non-skin side. In addition, in this specification, the "skin side" refers to the surface of the absorbent article or its constituent members that faces the skin side of the wearer when the absorbent article is worn, i.e., the side relatively closer to the wearer's skin. The "non-skin side" refers to the surface of the absorbent article or its constituent members that faces away from the wearer's skin when the absorbent article is worn. Here, "when worn" refers to a state in which the absorbent article is in a normal and proper wearing position, i.e., the correct wearing position of the absorbent article is maintained. In addition, in this specification, "plan view" refers to a plan view from the thickness direction Z.

As shown in FIG. 1, the panty liner 1 extends along the longitudinal direction X, and when worn, is fixed to the inner surface of the wearer's clothing by an adhesive portion (designated by reference numeral 6 in FIG. 2) arranged on the non-skin side 1b of the panty liner 1. The panty liner 1 has an absorbent body 4, which will be described later, and has the function of absorbing liquids such as menstrual blood, vaginal discharge, and urine (hereinafter also referred to as "body fluids").

As shown in FIG. 2, the panty liner 1 is composed of an absorbent body 4 , a top sheet 2 , a back sheet 3 , a second sheet 5 , and an adhesive portion 6 .
The top sheet 2 constitutes the skin side 1 a of the panty liner 1 .
The backsheet 3 constitutes the non-skin side 1 b of the panty liner 1 .
The adhesive portion 6 is provided on the non-skin side 1b.
The panty liner 1 has a configuration in which a back sheet 3, an absorbent body 4, a second sheet 5, and a top sheet 2 are laminated in a thickness direction Z. These components are appropriately joined together, for example, by bonding with an adhesive or heat sealing, or by embossing with compressed grooves.

<Components>
Each of the components constituting the panty liner 1 will now be described.

[Absorber]
The absorbent body 4 extends in the longitudinal direction X, and is disposed between the second sheet 5 and the backsheet 3. The absorbent body 4 absorbs bodily fluids from the skin side 4a, and diffuses them internally to retain the bodily fluids.
As the absorbent 4, any absorbent normally used in absorbent articles such as panty liners and sanitary napkins can be used without any particular restrictions. For example, a stack containing a fiber material such as pulp fiber and containing superabsorbent polymer particles as necessary, an absorbent paper containing a fiber material such as pulp fiber and containing superabsorbent polymer particles as necessary, an absorbent sheet in which superabsorbent polymer particles are disposed between two sheets of absorbent paper, and the like can be used.

As shown in FIG. 2, the absorbent body 4 has a laminated structure of two or more layers, in which the sheet-like absorbent sheet is arranged in a folded state, but it may also be an absorbent body with a single layer structure without folding. The absorbent body 4 may also be an absorbent core made of stacked fiber material or an absorbent core that is a mixed stack of fibers carrying particles of absorbent polymer, covered with a core wrap sheet.

In the panty liner 1, the top sheet 2, the second sheet 5 and the back sheet 3 have the same shape, and these overlap each other in a plan view to form the outer shape of the panty liner 1.
The absorbent body 4 has a length in the longitudinal direction X shorter than those of the top sheet 2, the second sheet 5 and the back sheet 3, and a length in the transverse direction Y shorter than the narrowest widths of the top sheet 2, the second sheet 5 and the back sheet 3. In a plan view, the top sheet 2, the second sheet 5 and the back sheet 3 extend outward from the entire periphery of the absorbent body 4, and these extended regions are joined to each other by a joining means such as an adhesive.

The absorbent body 4 is colored purple, for example, with a dye. When the panty liner 1 is viewed in plan from the top sheet 2 side, the purple color of the absorbent body 4 is visible through the top sheet 2 to the wearer. The colors of the panty liner 1 and the individual members that make it up will be described later.

The absorbent 4 contains a functional agent that can exert a specific function, such as an antibacterial agent or a deodorant. An absorbent containing an antibacterial agent or a deodorant can be produced, for example, by blending the antibacterial agent or the deodorant during production. By containing an antibacterial agent or a deodorant in the absorbent 4, which is the liquid-retaining layer, it becomes easier to effectively obtain a deodorizing effect against odors emanating from the body fluids retained in the absorbent 4, and the unpleasant odor felt by the wearer when wearing the absorbent can be reduced.

An antibacterial agent is typically an antibacterial substance that can exert a deodorizing effect by acting on the source of odor and suppressing the generation of odor. By having the antibacterial performance of acting on the source of odor, the unpleasant odor caused by excrement can be reduced. For this reason, in this specification, the concept of an antibacterial agent is included in the concept of a deodorant.
As the antibacterial agent, any antibacterial agent used for absorbent articles such as panty liners and sanitary napkins can be used without any particular limitation. Examples of the antibacterial agent include metals such as copper, silver, and gold, antibacterial metal-carrying substances such as metal-carrying porous particles, and organic antibacterial agents, and these can be used alone or in combination of two or more.

The deodorant is a substance that directly acts on odors, i.e., adsorbs, neutralizes, decomposes, etc., and exhibits a deodorant effect, and can be one that is widely used for deodorant purposes in the relevant technical field. For example, porous deodorant granules that have a wide deodorant spectrum for odors can be used.
In this way, by using a deodorant in addition to an antibacterial agent, the generation of bad odors can be further suppressed.

[Top sheet]
The top sheet 2 is made of a liquid-permeable sheet material, and is disposed above the second sheet 5 in the thickness direction Z. The skin side of the top sheet 2 constitutes the skin side 1 a of the panty liner 1 .
The topsheet 2 constitutes the outer shape of the panty liner 1 .
As the top sheet 2, there can be used, without any particular limitation, any material that is commonly used in absorbent articles such as panty liners, sanitary napkins, etc. The top sheet 2 is made of, for example, a polyolefin resin such as polyethylene or polypropylene, or a polyester resin such as polyethylene terephthalate.

As shown in Fig. 1, the topsheet 2 may have a plurality of apertures 14. The apertures 14 are through-holes that penetrate the topsheet 2 in the thickness direction Z. In the example shown in Fig. 1, seven aperture rows 140, each of which has a plurality of apertures 14 arranged along the vertical direction X, are arranged intermittently along the horizontal direction Y. A group of aperture rows each of which is made up of a plurality of aperture rows 140, is arranged in the center of the topsheet 2 in the horizontal direction Y over the entire length of the vertical direction X.
The multiple apertures 14 are arranged, for example, in a staggered pattern. The planar shape of the apertures 14 is not limited to the elliptical shape shown in Fig. 1, and may be, for example, a polygonal shape such as a triangle, a square, or a rectangle, or a star shape. Note that the apertures are not shown in the cross-sectional view of Fig. 2.
By providing a plurality of perforation rows 140, the downward migration of bodily fluids supplied to the topsheet 2 is improved.

[Second seat]
As in the panty liner 1 of this embodiment, a second sheet 5 may be disposed between the top sheet 2 and the absorbent body 4 .
The second sheet 5 is a sheet that serves the purpose of promoting the attraction of body fluids from the top sheet 2, improving the permeability of body fluids to the absorbent body 4, and reducing the return of body fluid absorbed by the absorbent body 4 back to the top sheet 2.
Any material that is commonly used in absorbent articles such as panty liners and sanitary napkins can be used without any particular limitation for the second sheet 5. For example, a hydrophilic nonwoven fabric or a hydrophilic fiber assembly can be used for the second sheet 5. Examples of nonwoven fabrics include air-through nonwoven fabrics, point-bonded nonwoven fabrics, resin-bonded nonwoven fabrics, spunlace nonwoven fabrics, and air-laid nonwoven fabrics.
The second sheet 5 is larger than the absorbent body 4 in a plan view and is positioned so as to cover the absorbent body 4. In the panty liner 1 of this embodiment, the second sheet 5 has the same shape as the top sheet 2 and the back sheet 3, and is disposed over the entire surface of the panty liner 1.

[Back sheet]
The backsheet 3 is disposed below the absorbent body 4 in the thickness direction Z. The non-skin side of the backsheet 3 constitutes the non-skin side 1 b of the panty liner 1 .
The backsheet 3 constitutes the outer shape of the panty liner 1 .
As the back sheet 3, any sheet that is commonly used in absorbent articles such as panty liners and sanitary napkins can be used without any particular limitation.
The back sheet 3 is formed of, for example, a sheet material having functions such as poor liquid permeability, water vapor permeability, water repellency, etc. As the sheet material, for example, a thermoplastic resin film or a laminate of the film and a nonwoven fabric can be used.
An adhesive portion (not shown) is provided on the non-skin side of the backsheet 3 for fixing the panty liner 1 to clothing.

The back sheet 3 is colored, for example, with a dye or the like, and has a green color. When the panty liner 1 is viewed in plan from the top sheet 2 side, the green color of the back sheet 3 is visible through the top sheet 2 to the wearer. Details will be described later.

<Each component of the panty liner and the color of the panty liner's appearance>
In this specification, chromaticity, lightness, and chroma are based on the L ^* a ^* b ^* color system (CIE1976(L ^* a ^* b ^* )) proposed by the International Commission on Illumination (CIE) in 1976.
The L ^* , a ^* , and b ^* values in the CIE1976 (L ^* a ^* b ^* ) color system can be measured by a color difference system. For example, they can be obtained by measuring the reflected light of the sheet using a handy spectral color difference system NF333 (product name) manufactured by Nippon Denshoku Industries Co., Ltd. under the measurement conditions of light source C and a viewing angle of 2°. At this time, it is preferable to measure using a white plate with an L ^* value of 95 or more as the background plate. Hereinafter, the CIE1976 (L ^* a ^* b ^* ) color system will be simply referred to as the L ^* a ^* b ^* color system.

[Appearance of individual component parts]
(Individual colors of the top sheet and second sheet)
The top sheet 2 and the second sheet 5 each have a white color by themselves.
In this specification, "white" includes white or achromatic colors close to white. In this specification, a white or achromatic color close to white member has a lightness L ^* value in the L ^* a ^* b ^* color system of preferably 90 or more, more preferably 95 or more.
In addition, with regard to the chromaticity a ^* value and b ^* value of the top sheet 2 and the second sheet 5, it is preferable that they are smaller than the chromaticity a ^* value of the purple color of the absorbent body 4, or larger than the chromaticity b ^* value of the purple color of the absorbent body 4, or smaller than the chromaticity a ^* value of the purple color of the absorbent body 4 and larger than the chromaticity b ^* value.

(Color of absorber alone)
The absorbent body 4 alone has a purple color.
In this specification, "purple" refers to a color in the fourth quadrant of the plane of chromaticity a ^* and chromaticity b ^* in the L ^* a ^* b ^* color space chromaticity diagram. In other words, "purple" refers to a color in the range where the chromaticity a ^* value is greater than 0 and the chromaticity b ^* value is less than 0.

(Back sheet color only)
The back sheet 3 has a green color by itself.
In this specification, "green" refers to a color in which the hue angle θ rotated counterclockwise around red (+a ^* axis) on the plane showing chromaticity a ^* and chromaticity b ^* of the L ^* a ^* b ^* color space chromaticity diagram is in the range of 90°<θ<270°, and preferably 90°<θ<210°. Note that the case where chromaticity a ^* is 0 is not included.

[Appearance of panty liner color]
(Color seen from the top sheet side)
3(A), when the panty liner 1 is viewed from the top sheet 2 side, the skin side 1a has a first colored region 21 that appears to have a color due to the purple color of the absorbent body 4 alone, and a second colored region 22 that appears to have a color due to the green color of the back sheet 3 alone. In the figure, the first colored region 21 is indicated by dense dots, and the second region 22 is indicated by sparse dots.
The first colored region 21 is a region where the absorbent body 4 is located in a plan view. The second colored region 22 is a region where the absorbent body 4 is not located in a plan view.

Both the top sheet 2 and the second sheet 5 are translucent. As a result, when the panty liner 1 is viewed from the top sheet 2 side, the purple color of the absorbent body 4 can be seen through the top sheet 2 and the second sheet 5 in the first colored region 21.
The purple color of the absorbent 4 is visible from the skin side 1a, allowing the wearer to visually recognize the presence of the absorbent 4, and furthermore, the purple color reminds the wearer of the deodorizing function of the absorbent 4, which contains an antibacterial agent and a deodorant, and allows the wearer to recognize the deodorizing area. In this way, the panty liner 1 can give the wearer a sense of visual security regarding the absorbency and the deodorizing function of deodorizing unpleasant odors when worn. Furthermore, the purple coloring makes bodily fluids less noticeable, reducing visual discomfort. In addition to reducing visual discomfort, the antibacterial agent and deodorant contained in the absorbent 4 reduce unpleasant odors, further reducing discomfort to the wearer when worn.
By making the absorbent 4, which has a deodorizing function and also exhibits a bodily fluid concealing effect, visible, when the panty liner 1 is worn on shorts or the like, the wearer is more conscious of the bodily fluid shielding effect and deodorizing function and is more conscious of wearing the panty liner 1 in the correct position so that the absorbent 4 is positioned in an appropriate position. As a secondary effect, when the panty liner 1 is worn in the correct position, leakage of liquid during wear is more easily suppressed, and the bodily fluid concealing effect and deodorizing function can be effectively exhibited.
Furthermore, purple is said to have the effect of healing sadness and anger in the heart, and is a color that gives a relaxing effect. For example, generally, warm colors such as red make the viewer feel warm, and cool colors such as blue make the viewer feel cold, whereas purple is a neutral color and does not easily evoke extreme images such as coldness or warmth. By providing an area on the skin side 1a where such purple can be seen, the psychological effect of purple can ease the wearer's melancholy mood from the beginning to the end of wearing, and a relaxing effect can be achieved.

In the panty liner 1, both the top sheet 2 and the second sheet 5 are translucent, so that when the panty liner 1 is viewed from the top sheet 2 side, the color resulting from the green color of the back sheet 3 is visible in the second colored region 22 through the top sheet 2 and the second sheet 5. In this embodiment, a case where the second colored region 22 is visually perceived as green is taken as an example.
In the panty liner 1, the difference in color between the first colored region 21 and the second colored region 22 allows the approximate outline of the absorbent body 4 to be visually recognized, thereby making it possible to grasp the shape and dimensions of the absorbent body 4. This allows the wearer to visually grasp the main absorption regions and deodorizing regions from the presence of the absorbent body 4, providing an increased sense of security regarding the absorption performance and deodorizing function.

In order to make it easier to visually recognize the presence of the absorbent body 4 by the difference in color between the first colored region 21 and the second colored region 22, it is preferable that the first colored region 21 has a larger chromaticity a ^* value and a smaller chromaticity b ^* value in the L ^* a ^* b ^* color system than the second colored region. The first colored region 21 has a stronger red color due to its larger chromaticity a ^* value, and a stronger blue color due to its smaller chromaticity b ^* value than the second colored region. Making the absorbent body 4 easier to visually recognize makes it easier to give a sense of security about the absorption performance.

It is preferable that the purple color of the first colored region 21 has a chromaticity a ^* value in the L ^* a ^* b ^* color system that is greater than 0 and equal to or less than 10, and a chromaticity b ^* value that is greater than or equal to -10 and less than 0.
It is preferable that the color of the second colored region 22 has a chromaticity a ^* value of -10 or more and less than 0, and a chromaticity b ^* value of -10 or more and 10 or less.
By setting the chromaticity a ^* value and chromaticity b ^* value of the first colored region 21 and the second colored region 22 in such ranges, when the panty liner 1 is viewed from the top sheet 2 side, the boundary between the absorbent body 4 and the back sheet 3 is made unclear, giving the wearer the impression that the absorbent body 4 does not stand out. Therefore, when the wearer looks at the panty liner 1 before wearing it, the panty liner is unlikely to give the wearer an impression that it is stiff in appearance, which is different from the actual situation, and the panty liner 1 can be given the impression that it is flexible and less uncomfortable to wear.

It is preferable that the difference in chromaticity a ^* value between the color of the first colored region 21 and the color of the second colored region 22 in the L ^* a ^* b ^* color system, when the latter is subtracted from the former, is 4 or more and 10 or less, and that the difference in chromaticity b ^* value between the color of the first colored region 21 and the color of the second colored region 22 in the L ^* a ^* b ^* color system, when the latter is subtracted from the former, is -10 or more and -2 or less.
By setting the chromaticity a ^* value and chromaticity b ^* value of the first colored region 21 and the second colored region 22 in such ranges, the boundary between the absorbent body 4 and the back sheet 3 becomes less clear when the panty liner 1 is viewed from the top sheet 2 side, giving the wearer the impression that the absorbent body 4 does not stand out as much. Therefore, in terms of appearance, the wearer can be given the impression that the panty liner 1 is less uncomfortable to wear.

On the skin side 1a of the panty liner 1, the first colored region 21 has a purple color, and the second colored region 22 has a green color.
By using the neutral colors purple and green on the entire skin side 1a, the psychological effect of the colors can ease the wearer's gloomy mood and provide a relaxing effect from the beginning to the end of wearing, and the coloring can reduce visual discomfort by hiding bodily fluids.

In addition, when the second sheet 5 is disposed between the top sheet 2 and the absorbent body 4 in the panty liner 1, it is more preferable to make the second sheet 5 white as in this embodiment. As a result, when the panty liner 1 is viewed from the top sheet 2 side, even if the purple color of the absorbent body 4 alone is a gaudy color, the absorbent body 4 is visible through the white top sheet 2 and second sheet 5, so the purple color of the absorbent body 4 alone does not look extreme, and the second colored region 22 can be viewed as a subdued color and does not give a gaudy impression.

(Color seen from the back sheet side)
As shown in Fig. 3(B) , when the panty liner 1 is viewed from the backsheet 3 side, the non-skin side 1b has a third region 33 and a fourth region 34. In the figure, the third region 33 is indicated by dense dots, and the fourth region 34 is indicated by sparse dots.
The third region 33 is a region of the non-skin side 1b where the absorbent body 4 is located in a planar view. The third region 33 overlaps with the first colored region 21 in a planar view. The third region 33 is a region where the topsheet 2, the second sheet 5, the absorbent body 4, and the backsheet 3 overlap in a planar view. The backsheet 3 is translucent, and when the panty liner 1 is viewed from the backsheet 3 side, the third region 33 is a region where the purple absorbent body 4 can be seen through the green backsheet 3. The third region 33 is visually perceived as a color close to gray because the green backsheet 3 and the purple absorbent body 4 overlap.
The fourth region 34 is a region of the non-skin side 1b where the absorbent body 4 is not located in a plan view. The fourth region 34 overlaps with the second colored region 22 in a plan view. The fourth region 34 is a region where the topsheet 2, the second sheet 5, and the backsheet 3 overlap in a plan view. When the panty liner 1 is viewed from the backsheet 3 side, the fourth region 34 appears green, which is the color of the backsheet 3 itself.

Here, after use, the panty liner 1 is generally disposed of in a rolled-up state from the vertical end with the skin side 1a facing inward. In this disposed state, the non-skin side 1b faces outward. In the panty liner 1, the non-skin side 1b is green, making it difficult to visually recognize absorbed bodily fluids such as menstrual blood from the non-skin side 1b. This reduces visual discomfort when disposing of the panty liner 1, and gives the wearer a sense of security that bodily fluids such as menstrual blood will be blocked when disposed of. Furthermore, even in the case of an unused panty liner 1 before being worn, the non-skin side 1b is green, giving the wearer a sense of security that bodily fluids such as menstrual blood will be visually blocked when disposed of.

When the panty liner 1 is viewed from the backsheet 3 side, the absorbent body 4 can be seen due to the difference in color between the third region 33 and the fourth region 34.
Typically, the panty liner 1 is packaged in an individual packaging sheet in an unused state from the viewpoint of hygiene and portability. When the panty liner 1 is packaged individually, the individual packaging sheet is arranged on the back sheet side, and the panty liner 1 is folded in two places and held in a triple-folded state when the skin side 1a of the panty liner 1 is the upper surface. When the panty liner 1 is put on shorts, etc., the wearer can see the non-skin side 1b and visually confirm the position of the absorbent 4 when the individually packaged panty liner 1 is unfolded and the individual packaging sheet is peeled off from the panty liner 1. This increases the wearer's awareness of the body fluid shielding effect and deodorizing function when putting the panty liner 1 on shorts, etc., to put the panty liner 1 in the correct position so that the absorbent 4 is located in an appropriate place.

The color of the third region 33 preferably has a chromaticity a ^* value in the L ^* a ^* b ^* color system of −30 or more and −10 or less.
The colors of the fourth region 34 are preferably colors whose hue angle ^θ rotated counterclockwise from red (+a ^* ) is in the range of ⁹⁰ °<θ<270° on the plane showing the chromaticity a ^* and b ^* values of the ^L *a*b* color space chromaticity diagram. Note that this does not include cases where the chromaticity a ^* and b ^* values are both 0.

It is preferable that the difference in chromaticity a ^* value between the color of the third region 33 and the color of the fourth region 34 in the L ^* a ^* b ^* color system, when the latter is subtracted from the former, is 1 or more and 10 or less, and that the difference in chromaticity b ^* value between the color of the third region 33 and the color of the fourth region 34 in the L ^* a ^* b ^* color system, when the latter is subtracted from the former, is -10 or more and -2 or less.
By setting the chromaticity a ^* value and chromaticity b ^* value of the third region 33 and the fourth region 34 in such ranges, the position of the absorbent body 4 can be more easily visually recognized when the panty liner 1 is viewed from the back sheet 3 side, making it easier to wear the panty liner 1 in the correct position.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.
For example, in the above embodiment, a panty liner (discharge sheet) is shown as an example of the absorbent article, but the absorbent article of the present invention is not limited to this. The absorbent article of the present invention may be a urine pad, a sanitary napkin, or the like.
