Description

The present invention relates to breast pads.

A breast milk pad is used for the purpose of preventing a breastfeeding mother from getting her underwear wet due to leakage of breast milk, and is worn by wrapping her breast inside underwear such as a brassiere.

As a breast milk pad, there is only one breast cover area that wraps around the breast, and in addition to the independent type (see, for example, Patent Document 1) that can be attached individually for each breast (cup part of underwear), the breast cover area can be left and right. A left and right integrated type that has a pair and is attached across both breasts (both cup portions) has also been proposed (see Patent Document 2, for example).

The breast-covering area of the breast-milk pad preferably has a three-dimensional cup shape in order to enhance the fit to the underwear and the breast. For this reason, in the technique disclosed in Patent Document 1, elastic members along the longitudinal direction are attached to the edges of the breast covering area on one side and the other side in the horizontal direction, and the shrinkage force of the elastic members causes the edge on the one side in the horizontal direction to move. It has been proposed to longitudinally shrink the portion and the other edge to form a cup.

In addition, in Patent Document 2, an elastic member along the horizontal direction is attached to the edges of the breast covering area on one side and the other side in the vertical direction, and the shrinkage force of the elastic member causes the edge on the one side in the vertical direction to move. and laterally contracting the other edge to form a cup-shaped breast covering area.

However, in the conventional breast milk pads having these elastic members, the anti-slip adhesive for fixing the wearing position is provided only in a narrow area between the elastic members in the breast cover area, so the cup portion of the underwear is not attached. If you repeatedly turn over the baby, feed it, and put it back, the non-fixed part near the edge (near the outer circumference), which does not have the anti-slip adhesive, may turn up or crumpled up. It was necessary to turn up the cup portion of the underwear again and fix the state of the non-fixed portion, which was a complicated operation.

SUMMARY OF THE INVENTION Accordingly, the main object of the present invention is to suppress curling and folding of the portion near the edge while molding the breast covering area into a cup shape with an elastic member.

The breast milk pad that solves the above problems is as follows.
<First Aspect>
a breast covering area that envelops the breast;
a pair of elastic members respectively attached to both sides of the breast covering region in a first direction perpendicular to the thickness direction;
The mounting portion of the elastic member is extensibly contracted in a second direction orthogonal to the thickness direction and orthogonal to the first direction by the contractile force of the elastic member, thereby forming the breast covering area into a cup shape. is molded,
An anti-slip adhesive for adhering to the underwear or the skin of the wearer is provided on both outer sides in the first direction of the main molding region defined as the portion having the pair of elastic members and the range therebetween, respectively. cage,
The anti-slip adhesive is not provided on both outer sides of the main molding region in the second direction,
The portion located between the anti-slip adhesives in the first direction has an elongation rate in the first direction of 5% or less,
A breast milk pad characterized by:

(Effect)
According to this breast milk pad, the portion closer to the edge than the pair of elastic members can be fixed to the underwear or the wearer's skin with the anti-slip adhesive, thereby fixing the portion closer to the edge in the first direction of the breast milk pad. Curling and folding can be effectively suppressed. In particular, even if the portion having the anti-slip adhesive or its vicinity is pinched and fixed while being pulled in the first direction, the elastic member expands and contracts substantially only in the second direction. The contracted part does not stretch, and the breast pad can be spread out and worn while maintaining the original cup shape.

On the other hand, when the anti-slipping adhesive is provided on both sides of the main molding area in the second direction (stretching direction), if the portion having the anti-slipping adhesive or its vicinity is pinched and fixed while being pulled in the second direction, The contracted portion is stretched by the elastic member, and cannot be fixed in the original cup shape. In addition, when the hand is released, the contractile force of the elastic member causes the elastic member to return to its original cup shape, which acts on the underwear to be fixed and the wearer's skin, deforming the cup portion of the underwear and causing the skin to become deformed. There is a risk of getting stuck. Further, even if the anti-slipping adhesive is provided on both sides of the main molding region in the second direction (stretching direction), the portion located between the anti-slipping adhesives in the first direction elastically expands and contracts in the first direction. and the same problem occurs. Therefore, in this breast milk pad, the anti-slip adhesive is not provided on both outer sides of the main molding area in the second direction, and the portion located between the anti-slip adhesives in the first direction is has an elongation rate of 5% or less (substantially does not elastically stretch).

<Second Aspect>
having only one breast covering area;
the first direction is lateral or oblique;
A breastfeeding pad according to the first aspect.

(Effect)
In the case of a stand-alone breastfeeding pad with only one breast covering area, if the anti-slip adhesive is provided on both lateral or diagonal sides of the main molding area, it will have the anti-slip adhesive when worn. The direction in which the part is pinched and pulled is horizontal or oblique, which facilitates the movement of the hand and facilitates the mounting work. Especially in the case of the type in which the non-slipping adhesive is fixed to the brassiere, depending on the size and shape of the brassiere, the breast milk pad protrudes above the cup part of the brassiere. , There is a risk that one anti-slip adhesive will not be fixed sufficiently. On the other hand, if the anti-slip adhesive is provided on both lateral or oblique sides, such a problem is less likely to occur.

<Third Aspect>
having a pair of integrated left and right breast covering areas,
the first direction is lateral;
A breastfeeding pad according to the first aspect.

(Effect)
In the case of an integrated breast milk pad in which a pair of left and right breast cover areas are integrated, if anti-slip adhesive is provided on both sides of the main molding area in the lateral direction, it will have an anti-slip adhesive when worn. If the direction in which the part is pinched and pulled is the lateral direction, the hand can be easily moved, and the mounting work is facilitated. Especially in the case of the type in which the anti-slip adhesive is fixed to the brassiere, depending on the size and shape of the brassiere, the breast milk pad protrudes above the cup part of the brassiere, so the anti-slip adhesive is placed on both sides of the main molding area in the vertical direction. If it is provided, there is a risk that one anti-slip adhesive will be insufficiently fixed. On the other hand, if the anti-slip adhesive is provided on both sides in the lateral direction, such a problem is less likely to occur.

<Fourth Aspect>
having a central region connecting the pair of left and right breast covering regions and side wings protruding laterally from each of the breast covering regions;
The anti-slip adhesive is provided on the inner surface of the central region and the inner surface of the side wings, respectively.
The breast pad of the third aspect.

(Effect)
Many women who need breast pads to sleep while breastfeeding use breast pads attached to their brassieres. However, wearing a brassiere while sleeping is not preferable because it causes discomfort due to tightness and stuffiness. On the other hand, if the breast milk pad is shaped like a brassiere as in the present embodiment, and the central region and the inner surface (skin side) of the side wings are provided with an anti-slip adhesive, the breast milk pad alone will adhere to the wearer's skin. Adhesive can be fixed. Therefore, according to this breast milk pad, it is possible to eliminate the need for a brassiere and reduce discomfort due to tightness and stuffiness.

<Fifth Aspect>
The side wing has an anti-slip adhesive at a position laterally spaced from the breast covering area, and has a laterally elastic stretchable portion provided between the anti-slip adhesive and the breast covering area.
The breastfeeding pad of the fourth aspect.

(Effect)
By providing the stretchable portion in the side wing in this manner, the breast milk pad can be deformed to follow the movement of the breast due to breathing or the like, and the feeling of wearing is improved.

<Sixth Aspect>
The central region incorporates an absorber that absorbs liquid in contact with the inner surface,
In the central region, the absorbent body protrudes on both sides in the longitudinal direction from the anti-slip adhesive.
A breast pad according to the fourth or fifth aspect.

(Effect)
As in this embodiment, it is more preferable to incorporate an absorber in the central region of the integral breast pad so that it can absorb sweat from the cleavage.

<Seventh Aspect>
The maximum lateral width of the anti-slip adhesive provided in the central region is the distance between the portion with the largest longitudinal dimension in one breast-covering region and the portion with the largest longitudinal dimension in the other breast-covering region. 0.15 to 0.20 times the lateral spacing;
A breastfeeding pad according to any one of aspects 4-6.

(Effect)
If the anti-slip adhesive is provided in the central area of the integrated breast pad, too wide an adhesive may cause a poor fit to the breast, and too narrow an adhesive may not be fixed. Since there is a possibility that it will be sufficient, it is preferable to keep it within the scope of this aspect.

<Eighth Aspect>
The width of the anti-slip adhesive provided in the central region expands toward both sides in the longitudinal direction,
A breastfeeding pad according to any one of aspects 4-7.

(Effect)
When the anti-slipping adhesive is provided in the central region of the integrated breast milk pad, the width of the anti-slipping adhesive may be constant in the longitudinal direction, but if it expands toward both sides in the longitudinal direction as in this aspect, , is preferable because it provides a good fit to the breast.

<Ninth Aspect>
The breast covering area incorporates an absorber,
The elastic member is arranged so that at least part of the second direction overlaps the absorber,
A breastfeeding pad according to any one of aspects 1-8.

(Effect)
As in this aspect, the contractile force of the elastic member is applied directly to the absorber, and the absorber and the absorber are formed into a cup-like shape, thereby further improving the fit to the breast.

<Tenth Aspect>
The pair of elastic members are elongated elastic members arranged in a curved line so that the distance between them becomes narrower toward both sides in the second direction.
A breastfeeding pad according to any one of aspects 1-9.

(Effect)
Arranging the elongated elastic members in a curvilinear shape as in this aspect is preferable because the breast covering area is molded into a more rounded cup shape.

ADVANTAGE OF THE INVENTION According to this invention, the advantages, such as being able to suppress curling and folding of the part near an edge, are provided, while shape|molding a breast-covering area|region by an elastic member in a cup shape.

Fig. 2 is a plan view showing the outer surface of the stand-alone breastfeeding pad; FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1; Fig. 10 is a perspective view showing a state in which a stand-alone breast milk pad is attached; Fig. 2 is a plan view showing the inner surface of the one-piece breast pad; FIG. 5 is a cross-sectional view taken along line BB of FIG. 4; Fig. 10 is a perspective view showing the state in which the integrated breast milk pad is attached; Fig. 10 is a plan view showing the outer surface of another stand-alone breastfeeding pad; Fig. 10 is a plan view showing the inner surface of another integral breast pad; Fig. 10 is a plan view showing the outer surface of another stand-alone breastfeeding pad; Fig. 10 is a plan view showing the inner surface of another integral breast pad; 11 is a cross-sectional view taken along line CC of FIG. 10; FIG. Fig. 10 is a plan view showing the inner surface of another integral breast pad; FIG. 13 is a cross-sectional view taken along line DD of FIG. 12;

Examples of breast pads will now be described in detail with reference to the accompanying drawings. The dotted pattern portion in the cross-sectional view shows the adhesive as a joining means for joining each component located on the front side and the back side, and the hot melt adhesive solid, bead, curtain, summit or spiral coating, or pattern coating (transfer of hot-melt adhesive by letterpress method), etc. Alternatively, or together with this, the fixed portion of the elastic member is formed by coating the outer peripheral surface of the elastic member with a comb gun or Surewrap coating. be. Hot-melt adhesives include, for example, EVA-based, adhesive rubber-based (elastomer-based), olefin-based, and polyester-polyamide-based adhesives, and can be used without particular limitation. As a joining means for joining each constituent member, a means by material welding such as heat sealing or ultrasonic sealing can be used.

In addition, as the nonwoven fabric in the following description, a known nonwoven fabric can be appropriately used depending on the site and purpose. Constituent fibers of non-woven fabrics include, for example, synthetic fibers such as olefin-based, polyester-based, and polyamide-based fibers such as polyethylene or polypropylene (including composite fibers such as core-sheath fibers in addition to single-component fibers), as well as recycled rayon and cupra. Fibers, natural fibers such as cotton, etc., can be selected without particular limitation, and these can also be mixed and used. In order to increase the softness of the nonwoven fabric, it is preferable to use crimped fibers as the constituent fibers. In addition, even if the constituent fibers of the nonwoven fabric are hydrophilic fibers (including fibers made hydrophilic by a hydrophilic agent), they are hydrophobic fibers or water-repellent fibers (including fibers made water-repellent by a water-repellent agent). ). In addition, nonwoven fabrics are generally classified into short fiber nonwoven fabrics, long fiber nonwoven fabrics, spunbond nonwoven fabrics, meltblown nonwoven fabrics, spunlace nonwoven fabrics, thermal bonded (air-through) nonwoven fabrics, and needle punched nonwoven fabrics, depending on the fiber length, sheet forming method, fiber bonding method, and laminate structure. Nonwoven fabrics are classified into nonwoven fabrics, point-bonded nonwoven fabrics, laminated nonwoven fabrics (such as SMS nonwoven fabrics and SMMS nonwoven fabrics in which a meltblown layer is sandwiched between spunbond layers), and any of these nonwoven fabrics can be used.

1 and 2 show an example breast pad 10. FIG. This mother's milk pad 10 is of a stand-alone type whose entirety serves as a breast covering area 20, and as shown in FIG. On the other hand, the breast milk pad 10 shown in FIGS. 4 and 5 has a pair of left and right breast covering regions 20, and is attached across both breasts (both cup portions) as shown in FIG.

The shape of the breast milk pad 10 is not particularly limited, and can be determined as appropriate. For example, a stand-alone breast pad 10 with an entire breast covering area 20 may have a rounded shape suitable for enveloping the breast, more specifically circular (illustrated), oval, oval, or rounded. Appropriate shapes such as triangles can be used. On the other hand, in the integrated breast pad 10, since both breast covering regions 20 are integrated, it can be, for example, a gourd type (see Patent Document 2), a spectacle type (example shown in FIG. 4), or the like. Also, part or all of the peripheral edge of the breast milk pad 10 may be frilled as shown in FIG. The one-piece breast pad 10 has a central region 21 connecting both breast covering regions 20 . Further, in an example described later, side wings 22 protrude to the sides of each breast covering region 20 . The boundary between the central region 21 and the side wing 22 breast covering region 20 is an imaginary straight line in the vertical direction LD that passes through the inflection point of the outer peripheral edge.

The dimensions of each part of the breast milk pad 10 can be determined as appropriate. For example, the longitudinal dimension 10y of the breast milk pad 10 can be about 120 to 140 mm. The lateral dimension 10x of the breast pad 10 can be 0.9 to 1.1 times the longitudinal dimension 10y for stand-alone breast pads 10 and It can be about 120 to 140 mm. The longitudinal dimension 20y of the breast covering area 20 can be similar to the longitudinal dimension 10y of the stand-alone breast pad 10, whether stand-alone or integral. In the integrated breast milk pad 10, the lateral dimension 21x of the central region 21 can be about 55 to 75 mm, and the minimum longitudinal dimension 21y of the central region 21 is equal to the longitudinal dimension 20y of the breast covering region 20. It can be about 0.5 to 0.8 times. Further, the longitudinal dimension 22y of the side wings 22 in the example described later can be about 1 to 1.5 times the longitudinal dimension 20y of the breast covering region 20, and the lateral dimension 22x is about 60 to 90 mm. can be done.

Each of these breast milk pads 10 comprises a liquid-permeable top sheet 11 forming a surface in contact with the wearer's skin, a liquid-impermeable sheet 12 forming a back surface, and an absorbent body 13 interposed therebetween. I have it. The breast milk pad 10 can be appropriately modified, for example, by omitting the top sheet 11 or the liquid impermeable sheet 12, or by forming only one sheet that can absorb and retain liquid.

As the absorber 13, a pile of pulp fibers, an aggregate of filaments such as cellulose acetate, or a non-woven fabric may be used as a basis, and a superabsorbent polymer may be mixed or fixed as necessary. . The fiber basis weight and the superabsorbent polymer basis weight in the absorbent body 13 can be determined ^as appropriate. / ^m2 . If necessary, the absorbent body 13 can be wrapped with a wrapping sheet 15 made of crepe paper, liquid-permeable nonwoven fabric, or the like.

The shape of the absorber 13 is generally a shape that follows the outer shape of the breast milk pad 10, and in the independent breast milk pad 10, for example, a circle (illustrated example), an oval shape, an oval shape, a rounded triangle shape, etc. , and the integral breast pad 10 can be, for example, a gourd shape (illustrated example) across both breast covering areas 20, a spectacle shape, a rectangular shape, etc., but is not limited to this, and any appropriate shape. For example, as shown in FIGS. 10 and 11, in a one-piece breast pad 10, both breast covering areas 20 may have separate absorbent bodies 13. FIG. The absorber 13 preferably occupies most of the breast covering area 20 (65% or more in terms of area), but may be provided only in a narrower area including the portion corresponding to the nipple.

The dimensions of the absorbent body 13 can be determined as appropriate. For example, the longitudinal dimension 13y of the absorbent body 13 can be about 0.65 to 0.95 times the longitudinal dimension 10y of the breast milk pad 10. FIG. In addition, the lateral dimension 13x of the absorber 13 is the lateral dimension 10x of the breast milk pad 10 in the case of the independent breast milk pad 10, and in the case of the integrated breast milk pad 10 having the left and right independent absorbers 13. can be about 0.5 to 0.7 times. In the case of a one-piece breastfeeding pad 10 and an absorbent body 13 spanning the left and right breast covering areas 20, the lateral dimension 13x of the absorbent body 13 extends from the side edge of one breast covering area 20 to the other breast covering area 20. It can be about 0.90 to 0.95 times the lateral dimension (20x+21x+20x) to the side edge.

As the liquid-impermeable sheet 12, in addition to a polyethylene film or the like, a moisture-permeable sheet can be used without impairing water impermeability in order to prevent stuffiness. For example, as the liquid-impermeable sheet 12, a microporous sheet obtained by forming a sheet by melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene and then stretching in a uniaxial or biaxial direction is used. can be used. Non-woven fabrics using microdenier fibers, non-woven fabrics in which air gaps between fibers are reduced by applying heat or pressure to enhance leakproofness, and water-repellent non-woven fabrics coated with a water-repellent agent are also used as the liquid-impermeable sheet 12. can be used as The liquid-impermeable sheet 12 preferably covers the entire absorber 13, but may cover only a part of it. When a resin film is used as the liquid-impermeable sheet 12, the rear surface thereof can be covered with a nonwoven fabric.

As the top sheet 11, a perforated or non-perforated nonwoven fabric, perforated plastic sheet, or the like is used. The top sheet 11 preferably covers the entire absorbent body 13, but may cover only a part of it.

As shown in the illustrated example, the peripheral portion of the breast milk pad 10 may have a flap 16 without the absorber 13, in which at least one of the top sheet 11 and the liquid impermeable sheet 12 protrudes. In particular, it is preferable that the entire flap 16 is a laminate of the top sheet 11 protruding from the outer periphery of the absorbent body 13 and the liquid-impermeable sheet 12 .

(elastic member)
A pair of elastic members 30 are attached to both sides of the breast covering area 20 in the lateral direction WD (first direction), and the attaching portions of the elastic members 30 are elongated in the longitudinal direction LD (second direction) by the contractile force of the elastic members 30. The ability to shrink, thereby forming the breast covering area 20 into a cup-like shape, is preferred for a better fit of the breast covering area 20 .

The elastic member 30 is preferably provided between the top sheet 11 and the liquid-impermeable sheet 12, and more preferably provided between the top sheet 11 and the absorbent body 13, so as not to come into direct contact with the skin. It is more preferable to provide the second sheet 14 on the back side of the top sheet 11 as shown in the figure, and to provide the second sheet 14 therebetween. As the elastic member 30, an elongated elastic member 30 such as a string-like, string-like, or band-like elastic member 30 is preferable. When spandex thread rubber is used as the elastic member 30, the thickness is preferably 470 to 1240 dtex. Moreover, the elongation rate of the attachment portion of the elastic member 30 is preferably 150 to 250%. When an elongated elastic member 30 is used as the elastic member 30, a plurality of elastic members 30 can be provided at intervals in a direction perpendicular to the stretching direction. The second sheet 14 can be selected from materials similar to those of the top sheet 11. The same material as that of the top sheet 11 may be used. A material different from that of the top sheet 11 may be used, such as a material with high durability.

In the breast milk pad 10 having the flaps 16 as shown, the elastic member 30 may be attached only to the peripheral flaps 16 of the breast milk pad 10, but at least part of the longitudinal direction LD ( When the middle part) is arranged so as to overlap with the absorber 13, the contractile force of the elastic member 30 acts directly on the absorber 13, and the entire body is molded into a gentle cup shape to fit the breast. It is preferable because the property becomes even better.

As in the example shown in FIG. 1 and the example shown in FIG. 4, the contraction direction of the elastic member 30 may be linear in the second direction. It may be curved (not including a straight line) along the circumference. That is, when employing the elongated elastic members 30 as in the illustrated example, the pair of elastic members 30 of the breast covering region 20 are arranged in a curved shape so that the distance between them becomes narrower toward both sides in the longitudinal direction LD. A rounded elongated elastic member 30 is preferable because the breast covering region 20 is molded into a more rounded cup shape. Further, as in the example shown in FIG. 9 and the example shown in FIG. 10, the elongated elastic member 30 may be intermittently attached in the stretching direction.

(anti-slip adhesive)
When the breast milk pad 10 is to be adhered to underwear, as shown in FIGS. When affixed to the skin, as shown in FIGS. 4 and 5, an anti-slip adhesive 40 can be provided on the surface of the breast milk pad 10 at an appropriate location. Although not shown, the anti-slip adhesive 40 may be provided on both the front and back surfaces of the breast milk pad 10 . In the product state, it is preferable to cover the anti-slip adhesive 40 with a release sheet 41 and peel off the release sheet 41 before use.

The anti-slipping adhesive 40 may be provided in the portion overlapping the absorbent body 13 as a whole, or may be provided in the flap 16 (the portion not having the absorbent body 13), or as in the example shown in FIG. It may be provided over the portion overlapping the absorber 13 and the flap 16 .

The type of anti-slip adhesive 40 is not particularly limited, but when applied to the wearer's skin, a known silicone gel that has sufficient adhesive strength , has little effect on the human body and skin , and is easy to remove. etc. can be used (see Patent Document 3, for example).

(Relationship between anti-slip adhesive and elastic member, etc.)
As shown in FIGS. 1 and 4, in both the independent type and integrated type, the anti-slip adhesive 40 is applied to the main molding region 17 defined as the portion having the pair of elastic members 30 and the range therebetween. (See the hatched portion in FIG. 4). Moreover, the anti-slipping adhesive 40 is not provided on both outer sides of the main molding region 17 in the longitudinal direction LD, and the portion located between the anti-slipping adhesives 40 in the lateral direction WD is elastically stretchable in the lateral direction WD. No (elongation rate in lateral direction WD is 0%). According to the breast milk pad 10, the portion closer to the edge than the pair of elastic members 30 can be fixed to the underwear or the skin of the wearer by the anti-slip adhesive 40, thereby the edge of the breast milk pad 10 in the lateral direction WD can be fixed. It is possible to effectively suppress curling and folding of the near portion. In particular, even if the portion having the anti-slip adhesive 40 or the vicinity thereof is pinched and fixed while being pulled in the lateral direction WD when the elastic member 30 is attached, the stretch direction of the elastic member 30 is substantially only the longitudinal direction LD. The contracted portion is not stretched by the member 30, and the breast milk pad 10 can be firmly spread and worn while maintaining the original cup shape.

On the other hand, when the anti-slipping adhesive 40 is provided on both sides of the main molding region 17 in the longitudinal direction LD (stretching direction), the part having the anti-slipping adhesive 40 or its vicinity is pinched and pulled in the longitudinal direction LD. When fixed, the portion contracted by the elastic member 30 is stretched and cannot be fixed in the original cup shape. In addition, when the hand is released, the contractile force of the elastic member 30 causes the elastic member 30 to return to its original cup shape, which acts on the undergarment to be fixed and the wearer's skin, deforming the cup portion of the undergarment and causing damage to the wearer's skin. There is a risk that it may become tangled. Further, even if the anti-slipping adhesive 40 is provided on both sides of the main molding region 17 in the longitudinal direction LD (stretching direction), the portion located between the anti-slipping adhesives 40 in the lateral direction WD is elastically stretchable in the lateral direction WD. If you do, the same problem will occur. Therefore, in the breast milk pad 10, the anti-slip adhesive 40 is not provided on both outer sides of the main molding area 17 in the longitudinal direction LD, and the portion located between the anti-slip adhesives 40 in the lateral direction WD is , the elongation rate in the lateral direction WD is 5% or less (there is practically no elastic expansion and contraction).

The longitudinal range of the portion having an elongation rate in the lateral direction WD of 5% or less should be wider than the longitudinal range of the anti-slip adhesive 40, but preferably wider than the longitudinal range of the main molding region 17. More preferably, it covers the entire lengthwise direction LD of the breast milk pad 10 . In addition, the stretch rate in the lateral direction WD of the portions located between the anti-slip adhesives 40 is preferably 5% or less, more preferably 0% (no elastic expansion/contraction). For example, in the example shown in FIG. 1 and the example shown in FIG. 4, only the elongated elastic member 30 is provided linearly along the longitudinal direction LD, and there is no other elastic member 30, so the breast milk pad The elongation in the transverse direction WD is 0% over the ten longitudinal directions LD. In addition, in the example shown in FIG. 7 and the example shown in FIG. 8, since the elongated elastic member 30 is provided in a curved shape, although the elastic member 30 is slightly elastically stretched in the horizontal direction WD, at least between the anti-slip adhesive 40 It is sufficiently possible to set the elongation rate in the lateral direction WD of the portion located at 5% or less. Furthermore, in the example shown in FIG. 9 and the example shown in FIG. 10, elastic members 31 are provided along the horizontal direction WD, but these are vertically outside the portions positioned between the anti-slip adhesives 40. , and is positioned on the outer side in the longitudinal direction of the main molding region 17, it is sufficient that the elongation rate in the lateral direction WD of at least the portion positioned between the anti-slip adhesive 40 is 5% or less. It is possible.

The dimensions of the anti-slip adhesive 40 can be determined as appropriate. For example, in a typical case, longitudinal dimension 40y can be about 0.25 to 0.55% of longitudinal dimension 20y of breast covering region 20 . Further, the lateral dimension 40x of the anti-slip adhesive 40 can be about 20 to 30 mm.

The main molding area 17 does not have to be provided with the anti-slip adhesive 40, but can be provided.

(Example of integrated breast pad)
Many women who need breast pads to sleep while breastfeeding use breast pads attached to their brassieres. However, wearing a brassiere while sleeping is not preferable because it causes discomfort due to tightness and stuffiness. In order to solve this problem, as shown in FIGS. 4 and 5, a central region 21 connecting a pair of left and right breast covering regions 20 and side wings 22 protruding laterally from each breast covering region 20 are provided. , an anti-slip adhesive 40 is provided on the inner surface of the central region 21 and on the inner surface of the side wings 22, respectively. In this way, when the breast milk pad 10 is shaped like a brassiere and the inner surface (skin side) of the central region 21 and side wings 22 is provided with the anti-slip adhesive 40, as shown in FIG. It can be adhesively fixed to the wearer's skin. Therefore, according to the present breast milk pad 10, it is possible to eliminate the need for a brassiere and reduce discomfort due to tightness and stuffiness. In the illustrated example, the members forming the side wings 22 are connected to the sides of the breast covering region 20, but the side wings 22 may be formed using a member continuing from the breast covering region 20 to the side wings 22. can also

The side wings 22 have an anti-slip adhesive 40 at a position laterally spaced from the breast covering area 20 and elastically stretchable in the lateral direction WD provided between the anti-slip adhesive 40 and the breast covering area 20. Having the stretchable portion 23 is preferable because the breast milk pad 10 can be deformed to follow the movement of the breast due to respiration or the like, and the feeling of wearing is improved. As in the example shown in FIGS. 4 and 5, when connecting the dedicated member that constitutes the side wing 22 to the breast covering region 20, if an elastic stretchable non-woven fabric is used as the dedicated member, the side wing 22 can be substantially stretched. It is also possible to use the entirety as the expansion/contraction portion 23 . Of course, as in the example shown in FIGS. 12 and 13, the stretchable portion 23 may be formed by attaching the elastic member 32 to the side wing 22 and contracting it so as to be stretchable in the lateral direction WD. The expansion ratio of the elastic portion 23 can be about 1.2 to 1.5%, and the dimension of the elastic portion 23 in the lateral direction WD can be about 60 to 80 mm. Further, the lateral dimension 40x of the anti-slip adhesive 40 in the side wings 22 can be about 20 to 30 mm.

When the central region 21 incorporates the absorbent 13 that absorbs liquid in contact with the inner surface (in the illustrated example, the absorbent 13 extends from one breast-covering region 20 through the central region 21 to the other breast-covering region 20). ), and in the central region 21, if the absorber 13 protrudes from the anti-slip adhesive 40 on both sides in the longitudinal direction LD, it is preferable because it facilitates the absorption of sweat in the cleavage.

When the anti-slip adhesive 40 is provided in the central region 21 of the integrated breast milk pad 10, if the width of the anti-slip adhesive 40 is too wide, the fit to the breast may deteriorate. Too much may result in insufficient fixation. Therefore, the maximum width (horizontal dimension 40x) of the anti-slip adhesive 40 provided in the central region 21 is equal to the maximum vertical dimension 20y of one breast-covering region 20 and the maximum vertical dimension 20y of the other breast-covering region 20 . Preferably, the directional dimension 20y is 0.15 to 0.20 times the lateral distance CC to the largest portion.

Further, when the anti-slip adhesive 40 is provided in the central region 21 of the integrated breast milk pad 10, the width of the anti-slip adhesive 40 may be constant in the longitudinal direction LD as shown in FIG. As shown, it is preferable to expand toward both sides in the longitudinal direction LD because the fit to the breast is improved.

The vertical dimension LD of the anti-slip adhesive 40 can be determined as appropriate, but the vertical dimension 40 y of the anti-slip adhesive 40 provided in the central region 21 is 40 y of the minimum dimension 21 y of the longitudinal direction LD of the central region 21 . The vertical dimension 40y of the anti-slip adhesive 40 provided on the side wings 22 is preferably about 50 to 85% of the vertical dimension 22y of the side wings 22.

(others)
In the illustrated example, elastic members 30 are provided on both sides of the breast cover region 20 in the lateral direction WD, and the direction of expansion and contraction by the elastic members 30 is the longitudinal direction LD. 40 is provided, but is not limited to this. That is, the elastic members 30 are provided on both sides of the breast covering region 20 in a direction (first direction) perpendicular to the stretching direction (second direction), and the anti-slip adhesive 40 is provided on both sides of the direction perpendicular to the stretching direction. , the expansion/contraction direction may be a direction other than the vertical direction LD (for example, the horizontal direction WD or oblique direction).

However, in the case of a stand-alone breastfeeding pad 10 having only one breast covering area 20, if the anti-slip adhesive 40 is provided on both sides of the main molding area 17 in the lateral direction WD or diagonally, it will not The direction of pinching and pulling the portion having the anti-slip adhesive 40 is the horizontal direction WD or the oblique direction, which facilitates hand movement and facilitates mounting work. Especially in the case of a type in which the anti-slip adhesive 40 is fixed to the brassiere, depending on the size and shape of the brassiere, the breast milk pad 10 protrudes above the cup part of the brassiere, so the anti-slip adhesive 40 is applied in the longitudinal direction of the main molding region 17. If it is provided on both outer sides of the LD, there is a risk that one anti-slip adhesive 40 will be insufficiently fixed. On the other hand, if the anti-slip adhesive 40 is provided on both sides in the lateral direction WD or in the oblique direction, such a problem is less likely to occur.

For the same reason, in the case of the integrated breast milk pad 10 in which the pair of left and right breast cover regions 20 are integrated, the anti-slip adhesive 40 is provided on both sides of the main molding region 17 in the lateral direction WD or diagonal direction. preferably.

<Description of terms in the specification>
The following terms in the specification have the following meanings unless otherwise specified in the specification.

- Undergarments are not limited to brassieres, but include tank tops and shirts with or without cups.

・Longitudinal direction LD means the vertical direction when worn. The lateral direction WD means the left-right direction when worn.

- "Elongation rate" means a value when the natural length is taken as 100%. For example, an elongation rate of 200% is synonymous with an elongation ratio of 2 times.

- "Matsuke" is measured as follows. After pre-drying the sample or test piece, it is left in a test room or apparatus under standard conditions (test location: temperature 23±1° C., relative humidity 50±2%) to a constant weight. Pre-drying refers to making a sample or test piece constant weight in an environment at a temperature of 100°C. Fibers with an official moisture content of 0.0% do not need to be pre-dried. Using a sampling template (100 mm x 100 mm), a sample with dimensions of 100 mm x 100 mm is cut from the constant weight specimen. The weight of the sample is measured, multiplied by 100 to calculate the weight per square meter, and used as basis weight.

・The “thickness” is automatically measured using an automatic thickness gauge (KES-G5 handy compression measurement program) under the conditions of a load of 0.098 N/cm ² and a pressurized area of 2 cm ² .

- "Unfolded state" means a flat unfolded state without contraction or slack.

・Unless otherwise specified, the dimensions of each part mean the dimensions in the unfolded state, not in the natural length state.

・If there is no description about environmental conditions for testing and measurement, the test and measurement shall be performed in a laboratory or equipment under standard conditions (test location: temperature 23±1°C, relative humidity 50±2%). do.
