Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a breast milk pad for a breastfeeding mother to interpose between an underwear such as a brassiere and a breast.
[0002]
[Prior art]
Conventionally, such a breast milk pad is used as shown in FIG. 8, for example.
In the figure, breast milk pads 1 and 1 each having a substantially circular dome shape are interposed one by one inside each cup 3 and 3 of the brassiere 2.
[0003]
As shown in FIG. 9 which is a front view and FIG. 10 which is a side view, such breast milk pads 1 and 1 are formed in a circular dome shape, and are configured by laminating a plurality of flexible materials in the thickness direction. Has been. That is, the breast milk pad 1 arrange | positions a surface material on the inner surface which contacts a user's skin directly, arrange | positions an absorber next, and a liquid oozes out from an absorber at least on the outer side, and it may stain clothes. The waterproof material is laminated so that there is no.
[0004]
An adhesive part 4 to which an adhesive or the like is applied is provided at a predetermined position on the surface side of the waterproof material, and the adhesive part 4 is affixed to the inside of the cup 3 of the brassiere 2 as shown in FIG. Use with fixing. Thereby, it is used so that underwear and breast milk pad 1 may not shift.
[0005]
[Problems to be solved by the invention]
By the way, such a breast milk pad 1 needs to be formed in a dome shape as described above so that it can be used in close contact with the front surface (not shown) of the user's breast.
In order to manufacture the breast milk pad 1 in such a shape, conventionally, it was as shown in FIG.
[0006]
In FIG. 11, after each material used as the main body of the breast milk pad 1 is laminated | stacked as mentioned above, it arrange | positions on the female type | mold 5 which has a bowl-shaped inner surface. Next, the male mold 6 having a dome-shaped convex surface as shown in the figure is lowered and pressed while being heated by the male mold 6 and / or the female mold 5.
Thereby, the main body of the heated breast milk pad 1 is formed in a dome shape.
[0007]
Therefore, in the manufacturing process, it is necessary to apply heat to deform into a dome shape. For example, the waterproof material of the above-described breast milk pad 1 uses a heat-deformable material such as polyethylene laminated paper.
For this reason, the breast milk pad 1 which is a product has a relatively hard texture after heat deformation as a whole, and as a product that is in direct contact with the user's skin, the touch felt on the skin is not necessarily good. .
[0008]
In this regard, the breast milk pad 1 softens the surface material (material directly in contact with the user's skin), and performs a special process in the vicinity of the periphery that is the seal portion between the surface material and the waterproof material, In some products, various considerations have been made to prevent the edges of the circular pad from causing unpleasant irritation. However, even if such a partial improvement is made, if the entire waterproof material is thermally deformed in the above-described process, it is inevitable that it will have a hard feel as a whole, and a product with a good feeling of use can be obtained. It was difficult.
[0009]
Further, even if the body of the breast pad 1 is thermally deformed as described above to form a dome shape, such processing has poor shape retention and becomes flat during use, and the front surface of the user's breast The shape becomes inconsistent with each other and the fitting property is deteriorated, resulting in misalignment. As a result, there is a problem that the breast milk leaks without being absorbed and stains the clothes.
[0010]
The present invention has been made to solve such a problem, and since it becomes a dome shape as a whole without heat treatment, it has a hard feel due to thermal deformation and a hard feel due to a material corresponding to the heat treatment. An object of the present invention is to provide a breast milk pad having a configuration that can avoid such a situation.
[0011]
[Means for Solving the Problems]
In the invention of claim 1, the object is to absorb the liquid, the waterproof material disposed outside the absorber, and the surface of the absorber opposite to the surface on which the waterproof material is provided. A breast milk pad formed by laminating and adhering to the surface material arranged on the body, and the elastic members are arranged on both side edges of the main body and arranged on the side in contact with the user's skin. The side edge of the surface material is folded back to the side opposite to the user's skin so as to wrap the side edge of the absorber inside, and the elastic member is absorbed at the side edge of the main body. The body and the folded surface material, or the folded surface material and the waterproof material, are fixed to each other, and both ends in the length direction of the elastic member are Not fixed to the body The configuration and the breast-milk pad having a land portion is achieved.
[0012]
According to the configuration of the first aspect, when the stretchable members are provided on both side edges of the main body, and when this portion is pulled along the direction in which the stretchable member is provided, the distance between the peripheral portions of the main body provided with the stretchable member is Shorter. For this reason, the main body has a shape in which the central portion protrudes in either direction, and can thereby be formed into a dome shape corresponding to the front shape of the breast.
Therefore, a breast milk pad having a shape that fits the shape of the breast can be obtained without subjecting the material to thermal deformation. Accordingly, since there is no material cured by heat, the hard material does not touch the user's skin and give an unpleasant feel.
[0013]
By providing the expansion / contraction member at the peripheral portion in this way, the shape of the dome-shaped main body is typically a “circular” shape, and is not only a perfect circle, but also a vertically and horizontally long shape. Any shape that does not have a large ratio is acceptable. For example, by arranging a plurality of expansion / contraction members relatively large (long) at the peripheral portion, such as a square or trapezoid with a rounded corner, the distance of the peripheral portion is shortened by the elastic force of the expansion / contraction member, and the dome This includes the case where it becomes a shape.
In addition, here, the “dome shape” or “dome shape” means that the cross section becomes a substantially semicircular shape with a convex center even if cut along any cutting line passing through the center of the main body. is there.
[0014]
Here, the breast pad main body can be formed into a dome shape without thermal deformation by the action of the elastic member, but this elastic member has a material to which the elastic member is fixed when contracted at the peripheral edge of the main body. And form a cocoon. For this reason, the heel part is a hard material, and when this touches a user's skin, an unpleasant touch may be given.
Therefore, in the configuration of claim 1, the side edge portion of the surface material arranged on the side in contact with the user's skin is placed on the side opposite to the user's skin so as to wrap the side edge portion of the absorber inside. Wrapping. Thereby, since the breast milk pad side edge is covered with a relatively soft surface material, even if such a portion comes into contact with the user's skin, an unpleasant feeling is not given.
In this case, the surface material may wrap only the side edge portion of the absorber, or may wrap the elastic member together with the side edge portion of the absorber.
Moreover, since the edge part of the expansion-contraction member which is long in one direction has a room part which is not fixed to the main body of a breast milk pad, especially a peripheral part, this peripheral part is no longer pulled inside. Thereby, since the peripheral part of a main body does not face inward, such a part directly hits a user's skin and does not give an unpleasant irritation.
[0015]
According to a second aspect of the present invention, in the configuration of the first aspect, in the side edge portion of the main body , the side edge portion of the surface material is folded back so as to wrap the elastic member together with the absorber. To do.
[0016]
According to the structure of Claim 2, in the area | region where the expansion-contraction member of the main body side edge part is arrange | positioned, this expansion-contraction member also encloses a surface material with an absorber, and makes the effect | action of Claim 1 still more complete. be able to.
[0019]
According to a third aspect of the present invention, in the configuration according to the first or second aspect, in the region where the both end portions of the elastic member are provided, the main body is more than the outer shape of the waterproof material and the surface material constituting the main body. Since the outer shape of the absorbent body is formed small, both ends of the elastic member form portions that are not fixed with respect to the waterproof material and the surface material, thereby configuring the room portion.
[0020]
According to the structure of Claim 3, in addition to the effect | action of Claim 2, since an absorber becomes smaller than a waterproof material, material cost can be saved.
[0021]
A fourth aspect of the present invention, in the construction of claims 1 to 3, substantially in the vicinity of the center, the waterproof material is the absorbent with respect to said elastic member is a direction in which elastic members extending in the side edges disposed in the main body It has a region that is not fixed to the body and / or the surface material.
[0022]
According to the structure of Claim 4, in the location where the expansion / contraction member of the side edge part of a breast milk pad main body is arrange | positioned, it can prevent that a waterproof material turns inside by being pulled by the expansion / contraction member.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiments described below are preferable specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. As long as there is no description of the effect, it is not restricted to these aspects.
[0024]
1 is a schematic perspective view of a breast milk pad according to an embodiment of the present invention as viewed from the inside, FIG. 2 is a plan view with the inside of the breast milk pad up, and FIG. 3 is a cross-sectional view taken along the line DD in FIG. 4 is a cross-sectional view taken along line EE of FIG.
With reference to these drawings, the structure of this embodiment will be described first.
[0025]
A waterproof material 11 is disposed on the outer side (lower surface side in FIG. 1) of the breast milk pad 10 shown in FIG. 1, and on the inner surface side (upper surface side in FIG. 1) in contact with the user's skin, A material 13 is arranged.
As shown in FIGS. 3 and 4, an absorbent body 12 is disposed between the surface material 13 and the waterproof material 11, and a cushion material 14 is disposed between the absorbent body 12 and the surface material 13. ing.
The outer shape of the waterproof material 11 and the absorbent body 13 constituting the shape of the main body 18 of the breast milk pad 10 is substantially circular, and the side surface portion is linear.
[0026]
The waterproof material 11 is a back sheet, and is fixed to the upper member in FIG. 3 by applying an adhesive to the location of the adhesive portion 11a. Although the waterproof material 11 does not allow liquid to pass through, it is preferable to select a material that is preferably flexible to a certain extent by allowing water vapor to pass therethrough and preventing water vapor. Further, the waterproof material 11 is formed of a flexible material as compared with a conventionally used heat-deformable waterproof material. As such a material, for example, a polyethylene film, a polyethylene laminate nonwoven fabric, a melt blown nonwoven fabric, or the like is used.
[0027]
The surface material 13 is a member that is in direct contact with the skin of the user, and a material that is well permeable to moisture such as breast milk and has a good texture is selected. That is, since the surface material 13 directly touches the skin of the user, a material suitable for this is selected in consideration of the good touch without damaging the skin more than necessary. Preferably, a dry mesh sheet (a mesh sheet formed of polyethylene or the like) or a nonwoven fabric is used. Particularly, the side edge portion 13a, preferably the entire peripheral edge portion of the surface material 13 is extended so as to wrap around to the opposite side (front side) so as to wrap around the absorber 12 and the elastic member 17 described later.
[0028]
As a result, the elastic member 17 expands and contracts in the length direction to cause wrinkles as shown in FIG. 1, or the side edges of the elastic member 17 face inward, and this portion comes into contact with the user's skin. However, since the contact portion is covered with a soft material such as a non-woven fabric, it does not give an unpleasant touch or irritation.
[0029]
In this connection, as can be understood by comparing FIG. 3 and FIG. 4, the waterproof material 11 is folded back at both side edges of the central portion of the main body 18 (near the line DD in FIG. 2). Further, portions 31 and 31 that are not bonded to the side edge portions 13a and 13a of the surface material 13 are provided. Thereby, when the elastic members 17 and 17 which will be described later act, when the side edges 13a and 13a of the folded surface material 13 are pulled in the direction toward the user's skin, the side edges of the waterproof material 11 Follows this, so that it does not touch the user's skin. For this reason, it can prevent that the waterproof material 11 which consists of a hard material compared with the surface material 13 contacts skin, and gives an unpleasant touch.
[0030]
For the absorbent body 12, a material excellent in liquid absorbency is selected. For example, a pulp fiber body, a laminated body, a sheet body, or the like is used. Further, the absorbent body 12 is preferably mixed with a polymer which is a granular material having a function of holding liquid as it is, semi-solidified or solidified, with excellent liquid absorbability in these pulp materials and the like. .
As such a material, for example, a water-absorbing polymer is suitable. For example, a polyacrylate copolymer, a hydrolyzate of starch-acrylonitrile graft copolymer, a starch-acrylic acid graft copolymer, polyvinyl Alcohol-acrylate copolymer, modified carboxymethyl cellulose and the like can be mentioned.
And the absorber 12 is wrapped in the tissue 15, as shown in FIG.3 and FIG.4. This prevents the granular polymer and the like from leaking.
As shown in FIG. 3, the tissue 15 is fixed at a position where the end portion 15 a surrounding the absorber 12 is shifted from the center of the main body 18.
[0031]
The cushion material 14 disposed between the absorbent body 12 and the surface material 13 is formed of, for example, a hydrophilic non-woven fabric having a predetermined thickness, whereby the material has a flexible bulge.
In this embodiment, the cushion material 14 is smaller than the outer periphery of the main body 18 and is provided only from the center.
[0032]
Moreover, as shown in FIG.1 and FIG.2, the surface material 13 is the direction which has the direction where the expansion-contraction members 17 and 17 are arrange | positioned on both sides across the area | region C where a user's nipple is contact | abutted. Concave grooves 16 and 16 are formed along the A direction.
As shown in FIGS. 3 and 4, the concave grooves 16, 16 press the main surface of the surface material 13 with a predetermined pressure using a technique such as an embossing treatment, and preferably are cushions. The material 14 is formed so as to be inserted. As a result, the surface material 13 and the cushion material 14 disposed below the surface material 13 are fixed by this groove, so that the surface material 16, the absorber 12, and the cushion material 14 that are members constituting the main body 18 are displaced from each other. Hard to occur.
[0033]
Further, as shown in FIGS. 3 and 4, each concave groove 16, 16 acts as a bent portion, and acts to bend the peripheral portion of the main body 18 in the direction of arrow B. Thereby, the whole can be formed in a more three-dimensional dome shape together with the action of the elastic member 17 described later.
Thereby, the whole area | region C which is the center part of the main body 18 becomes a recess, and a wearer's nipple (after-mentioned) is appropriately accommodated in the space corresponding to the area | region C, and unnecessary compression is given. Absent. Moreover, in the vicinity of the center of the region C, the cushion material 14 slightly swells in the thickness direction due to the action of the cushion material 14, so that the portion fits flexibly to the nipple.
In the cross-sectional views of FIGS. 3 and 4, the thickness of the breast milk pad is shown to be much thicker than the actual thickness for convenience of explaining the internal structure.
[0034]
Furthermore, in the breast milk pad 10, stretchable members 17, 17 are provided on both side edges of the main body 18. In this embodiment, the elastic members 17 and 17 are arranged substantially parallel to each other along the vertical direction (FIG. 1 or 2) of the product, and have a predetermined length. In this case, as shown in FIG. 3, the elastic members 17 and 17 are fixed to the absorbent body 12 at the position of the adhesive portion 17a through the tissue 15 or, preferably, the periphery thereof. Is wrapped around at least the side edge portion 13a of the surface material 13, preferably the entire periphery, and fixed at the location of the adhesive portion 17b.
Thereby, the member which receives the expansion / contraction action of the expansion / contraction member 17 becomes the flexible surface material 13 and the absorbent body 12, and the expansion / contraction member 17 is not fixed to the waterproof material 11, and therefore does not reach the waterproof material 11.
[0035]
For this reason, due to the action of the elastic member 17, the waterproof material 11 having a harder feeling than the surface material 13 does not form wrinkles at the peripheral edge portions 18 a and 18 a of the main body 18 corresponding to the location of the elastic member 17. The ridges become members other than the waterproof material 11, particularly the surface material 13 made of nonwoven fabric or the like.
As a result, as will be described later, the wrinkled portion made of a hard material does not come into contact with the sensitive skin near the breast of the wearer while wearing the breast milk pad 10, so as not to give an unpleasant feel. Yes.
In order to obtain substantially the same operation as this, the side edge 13a of the surface material may wrap only the absorber 12 instead of both the absorber 12 and the elastic member 17. In this case, if the expansion / contraction member 17 is disposed slightly inside the periphery, the surface material 13 and the absorbent body 12 are interposed between the user's skin and the heel of the waterproof material 11 to make it difficult to make direct contact. it can.
[0036]
Here, the expandable member 17 is formed of a material that expands and contracts in the length direction, and has a function of pulling the peripheral portion of the main body 18 where the expandable member is disposed so as to be shorter than the length of the material. Any form can be adopted.
[0037]
In this embodiment, the elastic members 17, 17 are formed of, for example, natural rubber that is long in one direction, an elastic film, an operon tape, or the like.
Due to the action of the elastic members 17, the substantially circular main body 18 is shortened in the entire circumference distance by elastically pulling a part of the peripheral edge thereof. For this reason, the center part of the main body 18 is deformed so as to be convex toward one side, thereby forming a dome shape or a bowl shape.
Here, the expansion members 17 and 17 are preferably arranged so as to be located on the back side (lower side in FIG. 3) with respect to the surface material 13 with respect to the cushion material 14. This is because even if the surface material 13 is interposed between the cushion material 14 and the elastic member 17, if the elastic members 17, 17 are arranged close to the user's skin, the touch is impaired and the wearing feeling is lost. Because it gets worse.
[0038]
Moreover, when the expansion-contraction member 17 is too close to the surface material 13, there is a case where the effect of appropriately shortening the peripheral portion due to the elastic contraction force may not be exhibited, and the expected function may not be obtained. Therefore, preferably, as described above, the elastic members 17 and 17 are fixed to the absorbent body 12 so as to be arranged on the periphery of the main body 18.
Further, the tissue 15 that wraps the absorbent body 12 is fixed so that the joint 15a is overlapped and fixed not at the center of the absorbent body 12 but at a position near the periphery, for example, as shown in the figure. Then, it becomes a part which does not hit a wearer's nipple, and an unpleasant touch is not given to a sensitive nipple.
[0039]
The expansion / contraction action of the expansion / contraction member 17 acts on the peripheral edge of the main body 18 and bends at the position of the concave groove 16 described above, so that the main body 18 becomes a three-dimensional dome shape, The area C portion protrudes.
In this case, if the concave grooves 16 and 16 are formed in a curved shape, the main body 18 can be formed into a cleaner dome shape.
For example, as shown in FIG. 2, the dome shape formed by providing the central portions 16 a, 16 a of each concave groove 16 in a curved shape so as to protrude toward the central portion of the main body 18 is a region. A substantially ideal conical dome shape in which the cross-sectional area decreases toward the center of the C side can be obtained.
[0040]
Further, the curved shapes of the concave grooves 16 and 16 can be provided in a curved shape such that the central portions 16 a and 16 a are convex toward the peripheral side of the main body 18, contrary to FIG. 2. In this case, in the dome shape formed by the bent portion that is the concave groove 16, a dome shape in which the area (volume) of the region C that is inside thereof is relatively large can be obtained.
Note that an adhesive portion as described with reference to FIG. 5 may be provided on the surface of the waterproof material 11 of the breast milk pad 10.
[0041]
Further, the breast milk pad 10 of the present embodiment has a vertically symmetrical shape in FIG. 2, and the stretchable member 17 is not disposed near the upper end and the lower end of the main body 18.
That is, the elastic member 17 is disposed along both side edges of the main body 18, and the upper and lower ends thereof are regions where the absorber 12 is provided, as can be understood by comparing FIG. 3 and FIG. 4. Somewhat exposed.
Here, in the breast milk pad 10 of this embodiment, since the structure of the four corners is common, the periphery of the location shown with the code | symbol F of FIG. 2 is expanded and shown in FIG. Will be explained.
[0042]
The breast milk pad 10 has a substantially circular main body 18 as a whole, and the side edges are linear because the elastic members 17 are provided on both sides. Therefore, as shown in FIG. 5, in the vicinity of the upper end, a corner portion 32 is formed at a location where the circular outer shape portion and the linear side edge portion intersect.
[0043]
In the region shown in FIG. 5, the absorbent body 12 including the tissue 15 is formed smaller than the outer shape of the surface material 13 and the waterproof material 11. That is, the surface material 13 and the waterproof material 11 have the same size and outer shape, and are attached to the front and back.
The upper end 15 b of the absorbent body 12 including the tissue 15 has a curve with substantially the same curvature as the upper ends of the surface material 13 and the waterproof material 11. The upper end 15b is continuous with a portion 15c having a smaller curvature that is curved in the opposite direction in the vicinity of the side edge, and continues to a substantially horizontal side edge upper end portion 15d.
[0044]
An upper end 17a that is one of end portions of the elastic member 17 protrudes from the side edge upper end portion 15d. That is, the upper end 17a of the elastic member 17 is exposed from the side edge upper end 15d of the absorbent body 12 including the tissue 15, but is disposed between the surface material 13 and the waterproof material 11 and is not exposed to the outer surface. . And the upper end 17a of this expansion-contraction member 17 becomes a free part which is not being fixed by adhesion | attachment etc. with any structural member of the main body 18 of the breast milk pad including the surface material 13 and the waterproof material 11 except the base part. ing. This portion is a room portion 17 a of the elastic member 17.
By configuring in this way, it is possible to configure a room for exhibiting the following actions without increasing the size of the main body 18 more than necessary.
[0045]
Thereby, the following effects are exhibited.
That is, as understood with reference to FIG. 6 shown for comparison, the upper end portion 17a of the elastic member 17 is bonded to the surface material 13 and the waterproof material 11 which are part of the main body 18. When fixed by the means, as shown in FIG. 6, the elastic member 17 contracts in the direction indicated by the arrow G based on its function. Thereby, the upper end portion 17a of the expansion / contraction member 17 exerts the action of making the entire main body 18 into a dome shape, and at the same time pulls the upper end of the side edge of the surface material 13 and the waterproof material 11 which are bonded together in the arrow G direction. .
For this reason, as shown in FIG. 6, the corner portions 32 of the surface material 13 and the waterproof material 11 face inward, and the corner portions 32 of the waterproof material 11 made of a harder material than the surface material 13. It is suitable for the user's skin. For this reason, this corner | angular part 32 hits a user's skin and gives an unpleasant irritation | stimulation.
[0046]
However, as shown in FIG. 5, if the upper end 17a of the expansion / contraction member 17 has a portion where the surface material 13 and the waterproofing material 11 are bonded to each other and an unfixed portion, the waterproofing material 11 has the above-described state. Therefore, it is possible to effectively avoid a situation in which the corner portion 32 does not face inwardly and gives an unpleasant stimulus to the user. Thereby, the elastic member 17 does not give an unpleasant stimulus to the user while appropriately making the body 18 of the breast milk pad into a dome shape.
Needless to say, in order for the elastic member 17 to exhibit such a function, the same configuration needs to be adopted at the upper and lower ends of each elastic member 17.
In addition, in the manufacturing process, such a room portion 17a is disposed only in a portion of the absorbent body 12 including the tissue 15 by arranging a stretchable member that extends long with respect to a body material that is long in one direction for constituting the body 18. This is caused by fixing the elastic member 17. Therefore, the end 17a of the elastic member 17 is redundant, and this portion may be cut out as a portion that does not contribute to its original function. In this case, a place where the end portion 17a does not exist, that is, a place where the elastic member 17 does not exist at the four corners of the main body 18 becomes a room portion.
[0047]
Here, if the size of the main body 18 can be made larger than in the case of FIG. 2, the area composed of the surface material 13 and the waterproof material 11 is made larger than in the case of FIG. In particular, without making the absorbent body 12 including the tissue 15 in a curved shape as described above, even if the shape is similar to the outer shape of the main body 18, it is possible to provide a room where the action of the elastic member 17 does not reach.
[0048]
FIG. 7 is a partially enlarged cross-sectional view illustrating a state where the user wears the breast milk pad 10. The front surface of the user's breast 25 has a substantially hemispherical shape like a bearded face, and a nipple 26 protrudes in the vicinity of the apex thereof.
On the other hand, the breast milk pad 10 of the present embodiment has a three-dimensional dome shape due to the action of the above-described expansion and contraction member 17 and the concave groove 16 as shown in the cross-sectional shape thereof, and the breast of the user The front surface of 15 can be covered substantially, and the teat 26 can be received in the recessed area C.
[0049]
As a result, like the breast milk pad formed by conventional heat treatment, when the time after mounting elapses, the mold holding cannot be maintained and the dome shape does not collapse and become flat. And the breast 25 are not misaligned. Due to the action of this point-concave groove 16, it is possible to hold the three-dimensional dome shape more effectively than when only the expansion member 17 is provided.
Moreover, by bending at the location of the concave groove 16 of the main body 18, the location of the region C protrudes to the front side as described in FIG. Thus, the nipple 26 is not compressed more than necessary. For this reason, the nipple 26 that is sensitive during the lactation period is not stimulated unnecessarily and does not give pain.
[0050]
Further, the cushion material 14 allows the surface material 16 to be softly brought into contact with the nipple 26, and the nipple 26 is held in the region C by the action of the concave groove 16, so that the contact position can be maintained. The situation in which the nipple 26 is detached from the effective absorbing surface of the surface material 13 and the breast milk leaks outside can be appropriately avoided.
[0051]
The present embodiment is configured as described above. As described above, the side edge 13a of the surface material 13 is folded back to the opposite side of the user's skin so as to wrap the side edge of the absorbent body 12 inside. Yes. Thereby, since the breast milk pad side edge is covered with a relatively soft surface material, even if such a portion comes into contact with the user's skin, an unpleasant feeling is not given.
That is, even if the expansion / contraction member 17 contracts, the waterproof material 11 that is harder than the surface material 13 can thereby form wrinkles at the peripheral edge portions 18a and 18a of the main body 18 corresponding to the location where the expansion / contraction member 17 is disposed. However, it becomes the surface material 13 which consists of members other than the waterproof material 11, especially a nonwoven fabric, etc. which become a wrinkle. For this reason, as shown in FIG. 7, the heel portion made of a hard material does not come into contact with the sensitive skin near the breast of the wearer in a state where the breast milk pad 10 is worn, and an unpleasant feel is not given.
[0052]
Further, in addition to this, the side edges 13a and 13a of the folded surface material 13 and the portions 31 and 31 where the waterproof material 11 is not bonded are provided at both side edges at the center of the main body 18. Thereby, when the elastic members 17 and 17 contract and the side edges 13a and 13a of the folded surface material 13 are pulled in the direction toward the user's skin, the side edges of the waterproof material 11 become Do not touch the skin of the user and touch the skin. Therefore, it is possible to prevent the waterproof material 11 made of a material harder than the surface material 13 from coming into contact with the skin and giving an unpleasant feel.
Further, the upper end 17 a of the elastic member 17 is not fixed to the surface material 13 and the waterproof material 11. For this reason, the corner | angular part 32 cannot face inward, and the situation which gives a user unpleasant irritation | stimulation can be avoided effectively.
