Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a breast milk pad for a mother in lactation to insert between underwear such as a bra and a breast.

[0002]

2. Description of the Related Art Conventionally, such a breast milk pad is used, for example, as shown in FIG. In the figure, a substantially circular dome-shaped breast milk pad 1, 1 is inserted inside each of the cups 3, 3 of the brassiere 2 one by one.

As shown in FIG. 6 which is a front view and FIG. 7 which is a side view, such breast milk pads 1 and 1 are formed in a circular dome shape, and a plurality of flexible materials are laminated in the thickness direction. It is configured. That is, the breast milk pad 1
Place a surface material on the inner surface that comes in direct contact with the user's skin,
Next, an absorbing material is arranged, and a waterproof material is laminated at least on the outside so that liquid does not seep out of the absorbing material and stain clothes.

[0004] At a predetermined position on the front side of the waterproof material, an adhesive portion 4 to which an adhesive or the like is applied is provided. As shown in FIG. 4 is attached and fixed. Thereby, the underwear and the breast milk pad 1 are used so as not to be displaced.

[0005]

By the way, in such a breast milk pad 1, it is formed in a dome shape as described above so that the breast milk pad 1 can be used in close contact with the front surface (not shown) of the breast of the user. There is a need to. In order to manufacture the breast milk pad 1 in such a shape, conventionally, as shown in FIG.

[0008] In FIG. 8, after the respective materials constituting the main body of the breast milk pad 1 are laminated and formed as described above, they are arranged on the female mold 5 having a bowl-shaped inner surface. Next, the male mold 6 having a dome-shaped convex surface as shown is lowered and pressed while heating with 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.

However, even if the main body of such a breast milk pad 1 is thermally deformed into a dome shape as described above,
Such processing is poor in shape retention, becomes flat during use, and does not conform to the shape of the front surface of the breast of the user, resulting in poor fit and misalignment. As a result, there is a problem in that breast milk leaks without being absorbed and soils clothes.

The present invention has been made in order to solve such a problem, and it is an object of the present invention to provide a breast milk pad which can be formed into a dome shape which is more three-dimensional and has excellent mold holding properties without heat treatment. It is an object.

[0009]

SUMMARY OF THE INVENTION The object of the present invention is to form a main body by laminating an absorbent for absorbing a liquid and a waterproof material disposed outside the absorbent. In the breast milk pad, the elastic members are arranged on both side edges of the main body, and a concave groove provided along a direction in which each elastic member extends, inside the position where each elastic member is arranged. Is achieved by having a breast milk pad.

According to the first aspect of the present invention, the elastic member is provided on both side edges of the main body, and when this portion is pulled along the direction in which the elastic member is provided, the peripheral edge portion provided with the elastic member of the main body is provided. Distance becomes shorter. For this reason, the body
The central portion has a shape protruding in either direction, whereby a dome shape corresponding to the front shape of the breast can be obtained. Here, in particular, since a concave groove provided along the direction in which each elastic member extends is provided inside the position where each elastic member is arranged, this groove is used as a bent portion and The part will bend. For this reason, the main body has a dome shape that is more three-dimensional and has excellent mold holding properties. Therefore, it is possible to obtain a breast milk pad that fits the shape of the breast without thermally deforming the material.

By providing the elastic member at the peripheral edge in this manner, the shape of the dome-shaped main body is typically a "circular" shape, and is not limited to a perfect circle.
Similarly, any shape may be used as long as the ratio of the length and width does not increase. For example, when a plurality of elastic members are arranged relatively large (long) in the peripheral edge, such as a square or trapezoid having an R-shaped corner, the distance between the peripheral edges is shortened by the elastic force of the elastic member, and the dome is formed. It includes the case where it becomes a state. Also, here, the "dome shape" or "dome shape" is a shape such that even if it is cut along any cutting line passing through the center of the main body, its cross-section becomes a substantially semicircular shape with a convex center. is there.

According to a second aspect of the present invention, in the configuration of the first aspect, the concave groove is provided in a curved shape along a direction in which the elastic member extends.

[0013] With this, the bent portion has a curved shape, so that a bent state more suitable for the dome shape can be obtained.

The invention according to claim 3 is characterized in that the concave groove is provided in a curved shape so as to protrude toward the center of the main body along the direction in which the elastic member extends. I do.

According to the configuration of claim 3, it is possible to obtain a substantially ideal conical dome shape in which the cross-sectional area decreases toward the vicinity of the center of the main body.

According to a fourth aspect of the present invention, in the configuration of any one of the first to third aspects, a surface material that is in contact with the skin of the user is provided on the surface of the absorber opposite to the surface on which the waterproof material is provided. And a cushion member is interposed between the absorber and the surface material.

According to the configuration of the fourth aspect, the surface material is pressed against the skin of the user by the action of the cushion material, so that the displacement is less likely to occur.

According to the fifth aspect of the present invention, in the configuration of the fourth aspect, the surface material is provided with concave grooves on both side edges on both sides of a contact position where a user's nipple is contacted. It is characterized by the following. The breast milk pad according to claim 4.

According to the fifth aspect of the present invention, since the surface material and the absorber and the like disposed therebelow are fixed by this groove, the members disposed in the main body are less likely to be displaced. In addition, since the both sides of the contact position of the nipple are recessed by the groove, a space where the nipple enters is formed, and at the same time, the contact portion, which is the central portion, rises and comes into soft contact with the nipple.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are added. However, the scope of the present invention particularly limits the present invention in the following description. The embodiment is not limited to these embodiments unless otherwise stated.

FIG. 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 facing upward, and FIG. It is a line sectional view. First, the structure of the present embodiment will be described with reference to these drawings.

A waterproof material 11 is arranged on the outside (the lower surface side in FIG. 1) of the breast milk pad 10 shown in FIG. 1, and a surface material 13 is arranged on the inner surface side (the upper surface side in FIG. 1). I have. As shown in FIG. 3, an absorber 12 is arranged between the surface material 13 and the waterproof material 11, and a cushion material 14 is arranged between the absorber 12 and the surface material 13. The outer shapes of the waterproof material 11 and the absorbent body 13 that constitute the shape of the main body 18 of the breast milk pad 10 are substantially circular.

The waterproof material 11 is a back sheet,
By applying an adhesive to the portion of the bonding portion 11a, the portion is fixed to the upper member in FIG. Waterproof material 11
Although it does not allow liquid to pass through, it is preferable to select a material that can transmit moisture and prevent stuffiness and has some flexibility. The waterproof material 11 is formed of a material that is more flexible than a conventionally used waterproof material that can be thermally deformed. As such a material, for example, a polyethylene film, a polyethylene laminated nonwoven fabric, a nonwoven fabric produced by a melt blow method, or the like is used.

The surface material 13 is a member that comes into direct contact with the skin of the user, and is made of a material that transmits moisture such as breast milk well and has a good texture. In other words, since the surface material 13 directly touches the skin of the user, a material suitable for the user is selected in consideration of a 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. The peripheral portion 13a of the surface material 13 is wrapped around to the opposite side, so that an absorber 12 and an elastic member 17 described later are provided.
It is arranged to wrap around.

As the absorber 12, a material excellent in liquid absorbency is selected. For example, a fibrous body, a laminated body, a sheet body or the like of pulp is used. Further, in the absorber 12, preferably,
These pulp materials and the like are mixed and used with a polymer which is a material having excellent liquid absorbability and a function of holding the liquid as it is or semi-solidified or solidified. As such a material, for example, a water-absorbing polymer is suitable, such as a polyacrylate copolymer, a starch-acrylonitrile graft copolymer hydrolyzate, a starch-acrylic acid graft copolymer, and polyvinyl. Examples thereof include alcohol-acrylate copolymers and modified carboxymethylcellulose. And the absorber 12 is shown in FIG.
As shown in FIG. This prevents the granular polymer and the like from leaking. The tissue 15 has an end 15 wrapped around the absorber 12.
a is fixed at a position shifted from the center of the main body 18 as shown in FIG.

The cushion member 14 disposed between the absorber 12 and the surface member 13 is formed of, for example, a hydrophilic non-woven fabric having a predetermined thickness, so that the material has a flexible bulge. ing. In this embodiment, the cushion member 14 is smaller than the outer periphery of the main body 18 and is provided only at the center.

As shown in FIGS. 1 and 2, the surface material 13 has an area C where the user's nipple abuts.
On both sides thereof, concave grooves 16, 16 are formed along the direction of arrow A, which is the direction in which the elastic members 17, 17 are arranged. As shown in FIG. 3, the concave grooves 16 are formed on the surface material 13 by using a technique such as embossing.
While pressing the main surface at a predetermined pressure, for example, 120 degrees Celsius.
Heat to about 150 degrees. And, preferably, it is formed so as to dig into the cushion material 14. As a result, the surface member 13 and the cushion member 14 disposed therebelow are fixed by the groove, so that the surface member 16, the absorber 12, and the cushion member 14, which are members constituting the main body 18, are displaced from each other. It is hard to occur. Also,
Each of the concave grooves 16 may have a depth with respect to the main body 18 depending on the groove portion, so that irregularities are provided in the groove. As a result, the shape of the embossment becomes uneven along the direction in which the groove extends, and the degree of compression of the members constituting the main body 18 is partially different. Thereby, the joining force between the members can be improved, and the strength of the entire main body 18 such as shape collapse is improved.

As shown in FIG. 3, each of the concave grooves 16 and 16 has a bent portion, and
In the direction of arrow B.
Accordingly, the whole can be formed into a more three-dimensional dome shape in combination with the operation of the elastic member 17 described later. As a result, the entire region C, which is the central portion of the main body 18, becomes a recess, and the wearer's nipple (described later) is appropriately accommodated in a space corresponding to the region C, and unnecessary compression is applied. Absent. In addition, in the vicinity of the center of the region C, the cushion member 14 functions to slightly swell in the thickness direction, so that the portion can be flexibly fitted to the nipple. still,
In the cross-sectional view of FIG. 3, for convenience of describing the internal structure,
The thickness of the breast pad is shown to be much thicker than it actually is.

Further, in the breast milk pad 10, elastic members 17, 17 are provided on both side edges of the main body 18. In this embodiment, the elastic members 17 are arranged substantially parallel to each other along the vertical direction of the product (FIG. 1 or 2), and have a predetermined length. In this case, as shown in FIG. 3, the elastic members 17, 17 are preferably fixed to the absorber 12 at the position of the adhesive portion 17a via the tissue 15, and furthermore, around the periphery thereof. Is wrapped around the peripheral portion 13a of the surface material 13, and the bonding portion 1
It is fixed at 7b. As a result, the members subjected to the expansion / contraction action of the expansion / contraction member 17 become the flexible surface material 13 and the absorber 12, and the expansion / contraction member 17 is not fixed to the waterproofing material 11 and thus does not reach the waterproofing material 11.

For this reason, by the action of the elastic member 17,
The waterproof material 11 having a relatively hard feel does not form wrinkles at the peripheral edges 18a, 18a of the main body 18 corresponding to the positions where the elastic members 17 are arranged.
Other members. As a result, as described later, in a state where the breast milk pad 10 is worn, a wrinkle portion made of a hard material contacts the sensitive skin near the breast of the wearer, so that an unpleasant feeling is not given. I have.

Here, the elastic member 17 is formed of a material that expands and contracts in the length direction, and has an action of pulling a peripheral portion of the main body 18 where the elastic member is disposed so as to be shorter than the length of the material. Any form can be adopted.

In this embodiment, the elastic members 17, 17
Is formed of, for example, natural rubber, a stretch film, an operon tape, or the like that is long in one direction. This elastic member 17,
By the action of 17, the substantially circular main body 18 has a part of its peripheral edge elastically pulled to shorten the distance of the entire circumference. For this reason, the central portion of the main body 18 is deformed so as to be convex on one side, and thereby has a dome shape or a bowl shape. Here, the elastic members 17, 17
The cushion material 1 is preferably used for the surface material 13.
4 or the absorber 12 (the lower side in FIG. 3). This is because the surface material 1 is located between the cushion material 14 and the elastic member 17.
This is because even when the elastic member 3 is interposed, if the elastic members 17, 17 are arranged close to the skin of the user, the touch is impaired and the feeling of wearing is deteriorated.

Further, if the elastic member 17 is too close to the surface material 13, the elastic shrinkage force may not be able to exert the effect of properly shortening the peripheral portion, and the expected function may not be obtained. Therefore, as described above, preferably, the elastic members 17, 17 are fixed to the absorber 12 so as to be arranged on the periphery of the main body 18. Further, the tissue 15 wrapping the absorber 12 is fixed so that the seam 15a is superimposed and fixed not at the center of the absorber 12 but at a location near the periphery, for example, as shown in the figure. Then, the nipple of the wearer does not hit the nipple, so that the sensitive nipple does not feel unpleasant.

The expansion and contraction action of the expansion and contraction member 17 acts on the peripheral edge of the main body 18 and bends at the above-mentioned concave groove 16 so that the main body 18 has a three-dimensional dome shape. The area C near the center protrudes. In this case, when the concave grooves 16, 16 are preferably formed in a curved shape, the main body 18 can be made to have a more beautiful dome shape. For example, as shown in FIG. 2, the central portion 16a of each concave groove 16 is
By forming the dome shape in a curved shape so as to protrude toward the center of the dome, a substantially ideal conical dome shape in which the cross-sectional area of the region C side decreases toward the vicinity of the center can be obtained. Can be.

The curved shape of each of the concave grooves 16 is
2, the central portions 16a, 16a may be provided in a curved shape such that they protrude toward the peripheral edge of the main body 18. 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 inside the dome shape 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.

FIG. 4 is a partially enlarged cross-sectional view illustrating a state in which the breast milk pad 10 is worn by the user. The front surface of the user's breast 25 has a substantially hemispherical shape like a bowl down, and a nipple 26 protrudes near the vertex thereof. On the other hand, the breast milk pad 10 of the present embodiment has a three-dimensional dome shape by the action of the above-described elastic member 17 and the concave groove 16 as shown by the cross-sectional shape thereof, and the breast of the user The nipple 26 can be received in the recessed region C while having a shape capable of substantially covering the front surface of the nipple 26.

As a result, unlike a breast milk pad formed by a conventional heat treatment, after a lapse of time after mounting, the dome shape cannot be maintained and the dome shape does not collapse and become flat after a lapse of time. There is no displacement of the mounting position between the breast milk pad 10 and the breast 25. By the action of the point-depressed groove 16, a more three-dimensional dome shape can be more effectively held as compared with the case where only the elastic member 17 is provided. Moreover, since the area C is bent at the concave groove 16 of the main body 18 to protrude to the front side as described in FIG. 2 and becomes a concave inside, the nipple 26 is accommodated in this part. Thus, the nipple 26 is not pressed more than necessary. Therefore, the nipple 26, which has become sensitive during the lactation period, is not unnecessarily stimulated and does not cause pain.

Further, the surface material 16 is softly brought into contact with the nipple 26 by the cushion material 14, and the nipple 26 is held in the area C by the action of the concave groove 16, so that the contact position thereof is changed. Since the nipple 26 can be maintained, the situation in which the nipple 26 deviates from the effective absorption surface of the surface material 13 and the breast milk leaks out can be appropriately avoided.

The present invention is not limited to the above embodiment.
For example, a plurality of cushion materials may be accommodated inside the main body 18. Further, the concave groove 16 may be formed only in the absorber 12 or the like that occupies most of the thickness of the main body 18 without being provided in the surface material 16. That is, the concave groove 16 may be partially provided in a part of the member constituting the main body 18 as long as it has a function of forming a bent portion. Further, for the waterproof material 11, the surface material 13, and the absorber 12, various materials other than the materials described in the above-described embodiment can be selected. Also, the main body 1
It is not necessary that all members constituting 8 are substantially circular,
It is sufficient that the whole formed by laminating different shapes is substantially circular. That is, if the member on which the elastic member is arranged is substantially circular, it can be held in a dome shape. Further, each component of each embodiment described above may be arbitrarily selected and combined.
