Description

  The present invention relates to a disposable breast pad used by lactating women to absorb breast milk (surplus milk) leaking from the breast (nipple).

  Breast milk is produced in large quantities by stimuli sucked by infants, but may leak even at other times. In addition, since the left and right breasts are interlocked, breastfeeding from one breast may occur if one breast is breastfeeding. For this reason, in order to prevent the clothes from getting wet with breast milk, breastfeeding mothers wrap their breasts inside underwear such as brassiere and intervene with a breast milk pad to absorb the breast milk. I am letting. Such a breast milk pad is generally formed by laminating a surface material directly in contact with the breast, an absorbent material for absorbing the breast milk, and a waterproof material for preventing the absorbed breast milk from leaking into the clothes. As shown in FIG. 11, the shape of the breast milk is such that the central portion bulges in advance so that the breast can be encased in order to increase the ease of attachment and the degree of adhesion to the breast at the time of attachment. A pad has been proposed.

Here, the breast milk pad is pressed by applying heat to the entire pad after stacking the planar sheets that are constituent members, but even if it is molded into a three-dimensional shape like a dome shape at the completion stage If retention is poor, the breast milk pad may become wet due to breast milk, or pressure may be applied to the breast milk pad itself due to the movement of the wearer, and the above shape will collapse, and the breast will not adhere to the user's breast. There was a problem. In addition, there is a problem in that the component milk is hardened by the heating for making the breast milk pad into a dome shape and the breast milk pad becomes hard. Therefore, the breast milk pad of the above conventional example is provided with a support member having a melting point lower than that of the waterproof material between the waterproof material and the absorbent body. As a result, in the step of forming into a dome shape, the breast milk pad can be formed into a dome shape by deformation of the support member by applying heat at a temperature lower than that of the waterproof material thermally deforming and higher than the melting point of the support member. (Patent Document 1).

  However, originally, when the whole breast pad is pressed, the absorbent material and waterproofing material are three-dimensionally shaped, but the surface material is not three-dimensionally shaped, while the surface material is also three-dimensionally shaped. When trying to do so, the texture becomes hard, and there is a problem that it causes friction due to direct contact with the skin and causes trouble. In this respect, in the above-described conventional example, since it is a support member disposed between the waterproof material and the absorbent body that is thermally deformed, the absorbent body and the waterproof material are easily three-dimensionally molded. However, the above-mentioned problems are not solved by the surface material that is not in direct contact with the material.

  On the other hand, in order not to make the surface material hard, a method of three-dimensional molding without applying heat may be employed in the central portion of the surface material that comes into contact with the nipple, but this does not three-dimensionally mold the central portion of the surface material Therefore, a gap is easily generated between the three-dimensionally shaped absorbent material and the surface material. Due to the existence of this gap, there is a problem that breast milk flows in the skin-appearing surface of the surface material or in the surface material and is not transmitted to the absorber, or the surface material comes into contact with the wearer's skin. . In this regard, even if the surface material and the absorbent body are joined with an adhesive, the absorbent body absorbs breast milk at the time of use, so that the adhesive force is reduced at the interface between the absorbent body and the adhesive. Clearance was likely to occur, and the absorption efficiency of breast milk was reduced, causing leakage.

  Therefore, in order to solve the problems as described above, in the present invention, by integrating the top sheet as the surface material and the back sheet as the waterproof material, while maintaining good dome shape retainability, A breast milk pad that can prevent the separation between the top sheet and the back sheet even in a wet state, more specifically, a line that integrally bonds the top sheet and the back sheet on a central line that passes through the center of the breast milk pad. Thus, a breast milk pad that can maintain the wearing state while maintaining a space between the nipple and the breast milk pad in a portion where the nipple is located is characterized.

More specifically, the present invention provides the following.
A liquid-permeable top sheet having a skin contact surface, a liquid-impermeable back sheet having a clothing contact surface, and an absorbent core interposed between the top sheet and the back sheet. A dome-shaped breast milk pad, further comprising a spacing portion formed by separating the absorbent core, wherein the spacing portion is formed to extend in a direction orthogonal to a direction in which the spacing portion is spaced. The breast milk pad is provided on a folding shaft that divides the breast milk pad into two parts, and a fixing part in which the top sheet and the back sheet are integrated is formed in the separation part.

  (1) A liquid-permeable top sheet having a skin contact surface, a liquid-impermeable back sheet having a clothing contact surface, and an absorbent core interposed between the top sheet and the back sheet And a substantially conical breastfeeding pad in which a fixing portion in which the top sheet and the back sheet are integrated directly or indirectly is formed in a portion positioned on the teat when worn.

  According to the present invention, the top sheet and the back sheet have a region that is partly fixed to a portion that comes into contact with the nipple when worn, and a gap is generated between the nipple and the breast milk pad in the worn state. . In addition, since the top sheet is integrated with the back sheet, it is prevented that only the top sheet is separated and floats even when the breast milk pad becomes wet with breast milk. For this reason, the frequency at which the wearer's nipple directly touches the top sheet can be significantly reduced, and the occurrence of friction between the nipple and the top sheet is prevented as much as possible to prevent unnecessary pressure on the nipple during wearing. It is possible to relieve discomfort and pain caused by stimulation.

  The breast milk pad according to the present invention has a substantially conical shape in use, but it is not necessary that all the constituent members are substantially circular, and the whole formed by stacking different shapes is almost the same. Any conical shape (including a heart shape) may be used. Also, depending on the angle of the cone head (the depth of the cup), the cone shape may be sharp or dome-shaped, but any shape that fits the breast is included. In addition, as a method of forming a conical shape with a series of top sheets and back sheets, a method including a gather portion formed by pinching part of opposite ends may be mentioned.

  The fixing of the top sheet and the back sheet may be performed indirectly in a region where an absorbent core disposed between both sheets is interposed, or directly in a region where no absorbent core is interposed as described later. You may go.

  (2) The adhering portion is formed in a line shape extending from one end portion to the other opposite end portion through the central portion of the breast milk pad, and forms a ridgeline in the mounted state (1) The described breast pads.

  According to the present invention, the adhering portion is formed along the center line of the substantially conical breastfeeding pad and becomes a shoreline in the mounted state. For this reason, the apex of the substantially conical breastfeeding pad is present on the fixed part, and the breastfeeding pad can be fitted to the breast by attaching the nipple to the fixed part.

  (3) The breast milk pad according to (1) or (2), wherein the breast milk pad has a non-arranged region of the absorbent core in at least a portion located on the teat.

  According to this invention, the area | region where the absorptive core is arrange | positioned, and the area | region which is not arrange | positioned coexist. For this reason, if it sees from the body side, the adhering part will have a dent toward the outside from the inside, and by positioning the nipple in this part, the separation state between the breast milk pad and the nipple can be further ensured. . Moreover, the magnitude | size of the space | gap part formed between a nipple and a top sheet at the time of mounting | wearing can also be adjusted with the difference in the thickness of an absorptive core. In particular, since the nipple is stretched more than usual during lactation, it is effective in avoiding contact between the top sheet and the nipple.

  (4) The breast milk pad according to any one of (1) to (3), wherein the absorbent core is composed of a pair of absorbent bodies, and the fixing portion is disposed between the pair of absorbent bodies.

  According to the present invention, since the absorbent core is formed by the pair of absorbers, the size of the gap can be adjusted not only by the thickness of the absorber but also by the spacing between the absorbers. For this reason, it is possible to cope with individual differences in the size of the nipple.

  (5) The breast milk pad according to any one of (2) to (4), wherein the shore line is a folding shaft that can be folded in a palm-like shape with the top sheet inside.

  According to the present invention, the breast milk pad is not three-dimensionalized at the stage of commercialization, but is three-dimensionalized by opening the folded breast milk pad at the stage of use. For this reason, it can be carried compactly in a folded state without worrying about the cup being crushed when it is carried, but a cup having a depth can be formed at the time of wearing. Moreover, since the center line is firmly molded, the cup shape maintenance function formed at the time of mounting is high. For this reason, shape loss at the time of use can be prevented more effectively.

  (6) The breast milk pad is formed by connecting and bonding the top sheet piece and the back sheet piece so that a pair of pad pieces formed so as to sandwich the absorber are adjacent to each other. The breast milk pad according to (5), wherein the folding shaft is formed in the joint portion.

  According to the present invention, one breast pad to be attached to one breast is configured by connecting a part of the peripheral edges of the two pad pieces to each other so as to have a substantially conical shape when attached. In this regard, when three-dimensional molding is performed at the time of molding like the breast milk pad of the conventional example, there is a problem that wrinkles are generated when trying to form a cup having a depth and the wearing feeling is impaired. Therefore, the cup is generally formed shallower in consideration of preventing wrinkles from occurring. However, breast-feeding busts are often considerably larger than normal, and such a milk pad with a shallow cup has a problem with its fit. In this respect, according to the present invention, it is possible to form a deep cup without causing wrinkles by appropriately changing the size of the pad piece. In addition, it is not molded by the entire press work, but it is molded by an adhesion process in which a closing margin having a certain width is provided and bonded at this part, so that the shape maintenance of the cup can be improved. It is possible. In addition, it is preferable that the joining range for joining a pair of pad pieces mutually is 30% or more and 50% or less with respect to the perimeter.

  The pair of pad pieces are preferably shaped so as to be mirror-symmetric with respect to the connecting and adhering portion so as to be exactly overlapped when folded, but can be adapted to a wider variety of breast shapes. Therefore, it can also be made asymmetric. For example, one of the pair of pad pieces can be enlarged or one can be provided with a notch. By doing in this way, it can prevent that a breast milk pad protrudes from underwear, such as a brassiere.

  (7) The breast milk pad according to (5) or (6), wherein the folding axis is a curved line having a continuous curvature or two straight lines having a continuous position.

  According to the present invention, since the folding shaft that is the folding portion forms a tangential line, the folding shaft is convex toward the clothes when worn. For this reason, it is easy to fit the breast pad to the breast at the time of wearing. In addition, it is preferable that this folding axis is comprised along the curve in which a curvature is gradually reduced toward the upper side of a breast at the time of wear along a breast shape.

  (8) The breast milk pad according to any one of (5) to (7), wherein the breast milk pad is displaced downward when the apex portion bisects the folding axis in the length direction.

  According to this invention, it arrange | positions so that the highest part of the cup of a breast milk pad may be a little lower than the center of a breast at the time of wear. This is because women's nipples are generally located slightly below the center of the bust, and especially because breastfeeding is often performed by infants from the bottom of the bust. Since this is remarkable, it is adapted to the position of such a nipple. Such a shape makes it possible to further improve the fit to the breast.

  As described above, according to the present invention, since the top sheet and the back sheet are directly or indirectly fixed, the top sheet is removed from the absorbent core even when the breast milk pad becomes wet during use. Since it can prevent separating, it is hard to leak, and the liquid residue to skin can be prevented, it can be set as the breast milk pad which can keep a nipple clean. Moreover, by doing in this way, even if the breast milk pad is three-dimensionalized into a suitable dome shape, wrinkles that harden the top sheet in contact with the skin or deteriorate the texture are not generated. Furthermore, since the shape maintaining property is excellent even in the mounted state, it is possible to provide a breast milk pad that can alleviate the occurrence of stimulation caused by friction due to the contact between the nipple and the breast milk pad.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below are various technically preferable limitations because they are preferable specific examples of the present invention, but 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.

<Basic structure of breastfeeding pad>
FIG. 1 is an external perspective view of a breast milk pad according to the present embodiment as viewed from the surface that comes into contact with clothes, FIG. 2 is a sectional view taken along line XX of FIG. 1, and FIG. FIG. 4 is a diagram for explaining a top portion of the breast milk pad at the time of wearing, and FIGS. 5 and 6 are schematic cross-sectional views showing the internal structure of the breast milk pad when worn. 7 and 8 are external perspective views of the breast milk pad as seen from the body side.

  As shown in FIG. 1, the breast milk pad 1 of the present embodiment has a three-dimensional conical shape at the time of wearing, and is easy to fit in a bust. The breast milk pad 1 is configured by forming a film by bonding the pad piece 2 and the pad piece 3 to each other by heating and pressurizing them and bonding them at the connecting portion 4. Specifically, as shown in FIG. 2, a liquid-permeable top sheet piece 21 in contact with the skin, an absorbent body 22 for absorbing breast milk, and a liquid-impermeable back sheet piece 23 in contact with underwear are laminated. And a pad piece 3 in which a top sheet piece 31, an absorbent body 32, and a back sheet piece 33 are laminated. The pad piece 2 is bonded so that the top sheet piece 21 and the back sheet piece 23 wrap the absorber 22, and the pad piece 3 is similarly bonded to the top sheet piece 31 and the back sheet piece 33. And a part of the adhesion part which comprises the periphery of the pad piece 2 and the pad piece 3 adheres mutually, and both are connected, The coupling | bond part 4 of the breast milk pad 1 is formed. And the other adhesion | attachment part forms the periphery of the breast milk pad 1 without adhering mutually. The connecting portion 4 forms a ridge line that becomes the central line of the breast milk pad 1 when worn.

  Even if the topsheet piece 21 and the topsheet piece 31 become wet due to the breast milk leaked from the nipple when worn due to the presence of the coupling portion 4, they are separated from the absorbent body 22 and the absorbent body 32 and are put on the nipple of the wearer. The nipple can be protected without touching it.

  Since the pad piece 2 and the pad piece 3 are mirror-symmetrical shapes, as shown in FIG. 3, before use, the coupling portion 4 so that the top sheet piece 21 and the top sheet piece 31 are in contact with the skin contact surface. It can be folded so that both are stacked on the axis. As a result, the portable device can be made compact while being carried, and the cup can no longer be carried in a molded state. Therefore, it is possible to avoid a situation in which the substantially conical shape suitable for use collapses and does not fit into the breast.

  The pad piece 2 is not a beautiful semicircle, but is shaped like an egg shape. This is because the longest part in the width direction, that is, the top part which is the top part of the cup of the breast milk pad 1 at the time of wearing, opened the pad piece 2 and the pad piece 3 to the left and right as shown in FIG. This is due to the fact that it is located slightly below the center in the length direction of the central line, which sometimes becomes a tomb line. This shape is adapted to the condition of the breast that the nipple of a lactating woman is located below the center, and for this reason, with the top part T as a boundary, A is larger than B. In order to obtain such a shape, the radius of curvature decreases from R1 to R2 with the top portion T as a boundary as shown in FIG. The part T will be arranged. In consideration of the breast size of a breastfeeding woman, the length of the pad piece 2 is preferably 100 mm to 200 mm, the width M is 50 mm to 100 mm, the length L is 125 mm, and the width M Is most preferably 75 mm.

  As shown in FIG. 5 which is a view of the wearing state seen from the side of the wearer's body and FIG. 6 which is a view seen from the upper side, the breast milk pad 1 has a top portion T which is the top of the cup when worn. On the inside, there is a gap between the breast and it is in a state of being separated without contacting the wearer's nipple. For this reason, it is not necessary to soften the central part of the breast milk pad 1 in consideration of contact with the nipple, and the shape retention of the cup can be improved. Further, even when the breast milk pad becomes wet, the nipple does not get wet, and the sensitive nipple can be kept clean.

  As shown in FIG. 7, when the pad 22 and the pad 3 are opened to the left and right when the absorbent body 22 and the absorbent body 32 that are separated in the folded state are opened, the breast milk pad 1 comes into contact with the coupling section 4. It is like that. For this reason, it is possible to quickly absorb the breast milk leaked from the nipple. However, since there are individual differences in the length and size of the nipple, as shown in FIG. 8, the pad piece 2 and the pad piece 3 are placed so that the absorbent body 22 and the absorbent body 32 are separated even when worn. Can be combined. Thereby, the space | gap part between the nipple at the time of mounting | wearing and the breast milk pad 1 can be made wider.

<Other embodiments>
FIG. 9 is a developed view of a breast milk pad made up of a series of top sheets and back sheets as seen from the skin contact surface, and FIG. FIG.

  According to this embodiment, the breast milk pad 10 is configured such that a mirror-symmetrical absorbent body 13 and absorbent body 14 are sandwiched between a series of topsheet 11 and backsheet 12 as shown in FIG. And by gathering the part of the area | region 15 and the area | region 16 enclosed by the dotted line, it is three-dimensionally molded as shown in FIG.

<Constituent material>
A hydrophilic fiber nonwoven fabric can be used for the top sheet, but a hydrophobic fiber nonwoven fabric having a large number of pores can also be used.

  The back sheet includes a breathable liquid-impervious stretched plastic film containing inorganic fine particles such as silica and alumina, a laminate of a liquid-impervious film and a fiber nonwoven fabric, and a breathable liquid-impervious film and a fiber nonwoven fabric. Laminate etc. can be used. Moreover, the composite nonwoven fabric which laminated | stacked the spun bond nonwoven fabric and the meltblown nonwoven fabric may be sufficient.

  The absorber is a mixture of particulate or fibrous superabsorbent polymer and fluff pulp, or a mixture of particulate or fibrous superabsorbent polymer, fluff pulp and thermoplastic synthetic resin fiber, and a predetermined What is compressed to the thickness of can be used. Due to this compression, the rigidity of the absorber is higher than that of the above-described synthesis of the top sheet and the back sheet. In addition, it is preferable that the absorbent body is entirely encased in a tissue paper in order to prevent the deformation of the absorber and the dropping of the polymer.

  The absorbent body is bonded to the inner surface of the top sheet or the back sheet with a hot melt adhesive or the like via a tissue paper. Spunbond is a composite nonwoven fabric in which a fiber nonwoven fabric by melt-blown method with high fiber density is used instead of tissue, and a fiber nonwoven fabric by spunbond method having high strength and good flexibility is laminated on at least one side of this fiber nonwoven fabric. It is also possible to use SM nonwoven fabric or SMS nonwoven fabric obtained by laminating a melt blown in multiple layers. In the case of this composite nonwoven fabric, since the fibers themselves are hydrophobic, it is preferable to perform a hydrophilic treatment in order to improve the liquid permeability to the absorbent body.

  The adhesive is preferably applied to the sheet or nonwoven fabric in any of spiral, wave, zigzag, dot, and stripe shapes. If an adhesive agent is apply | coated to a sheet | seat or a nonwoven fabric in those aspects, those sheets will adhere intermittently and an absorber will be joined to a sheet | seat intermittently. As the adhesive, a hot-melt type adhesive or the like is used, and either an olefin-based adhesive or a styrene rubber-based adhesive can be used.

  Examples of means for bringing the breast milk pad into close contact with clothing include applying a styrene rubber adhesive to the back sheet or attaching a male mechanical fastener having a plurality of hooks.

  As the fiber nonwoven fabric, a nonwoven fabric produced by a spunlace, needle punch, melt blown, thermal bond, spun pond, or chemical bond manufacturing method can be used. The hydrophilic fiber nonwoven fabric can be made from any one of synthetic fibers, semi-synthetic fibers and regenerated fibers that have been subjected to hydrophilic treatment, or composite fibers obtained by mixing these fibers. The hydrophobic fiber nonwoven fabric can be made from synthetic fibers. The hydrophobic fiber nonwoven fabric may contain semi-synthetic fibers or regenerated fibers that have been subjected to water repellent treatment. Although there is no limitation in particular in a synthetic fiber, a polyester type, a polyacrylonitrile type, a polyvinyl chloride type, a polyethylene type, a polypropylene type, and a polystyrene type can be used. As the synthetic fiber, a core-sheath type composite fiber, a parallel type composite fiber, an atypical hollow fiber, a microporous fiber, a bonded type composite fiber, or the like can be used.
