Abstract

To provide an absorbent breast pad and a method of producing the breast pad. The breast pad can be relatively easily manufactured, causes less irritation to the skin of a user, and has excellent shape retaining ability. The breast pad has a material formed by layering on each other a back sheet of no liquid permeability, a top sheet of liquid permeability, and an absorbent for absorbing and retaining liquid. The top sheet and the back sheet are joined to each other at their outer peripheral edge parts. A cutout formed by cutting out the absorbent is located at the outer peripheral edge part and is formed such that its widths gradually decrease inward. The top sheet is joined to the back sheet on the inside of the cutout. The breast pad also has a joint that is a portion at which the top sheet inner surfaces superposed on each other at the cutouts are joined together. In the joining of the top sheet inner surfaces, the top sheet is positioned on the inside of the pad with the pad folded along a bend line crossing a vertex of the cutout and the whole body. The direction of extending the folding line at the joint corresponds to a line connecting top and bottom when the breast pad is in use.

Description of the invention: [Technical field to which the invention pertains] Underwear and breasts such as a bra The present invention relates to an improvement of a breast pad and a method of manufacturing the same for a mother-feeding device for breastfeeding. [Prior Art] Two 'milk=materials capable of absorbing breast milk, most of which form, for example, a circle I:: the front of the breast is used in close contact, and the convex surface is formed to form the convex shape, and the outer cymbal of the genus 'For example, a flat circular material located outside, pressed under the heating on the convex surface two: and:? Forming. The conformality of such products is poor, and if the convexity X is deteriorated, the position is biased. (4) The problem that the breast milk is absorbed and leaks and defaces the clothes. On the other hand, in the case of a circular or approximately circular product, a swarf composed of an elastic body such as rubber is provided in the longitudinal direction to form a convex shape having a good shape retention property (see Patent Document 1). In the field, the circular absorber is cut along the radius of the circular absorbent body, and the convex-shaped convex surface is formed by joining the sector-shaped portion of the cut (refer to Patent Document 2). The η kinds of techniques are known to have a substantially common structure (see: two (one), etc.). These productivitys are all inferior, and it is a product which must be joined by itself, and there is a disadvantage that troublesome procedures are required. Therefore, 'others with different constructs are known to overlap the sheets in half, and 312XP/invention manual (supplement)/96-07/96114962. 200841833 follows the way of bending the side toward the opening and gradually becomes larger in width, will be two The structure in which the side edges are cut and joined (refer to Patent Document 6). Further, in another different configuration, each of the radii along the opposing positions of the circular absorber forms a scalloped portion, and in each of the notches, an elastic body is disposed in the transverse direction to cause a narrowing of the fan shape. In the case of contact with the breast, the breast is pressed by the contraction of the elastic body, and the sputum is applied (see Patent Document 7). _ [Patent Document 1] Japanese Patent Laid-Open No. Hei No. Hei No. Hei No. No. 59,944,434 [Patent Document 3] Japanese Patent Publication No. Hei 3-29284 [Patent Document 4] Japan [Patent Document 5] US Patent Registration No. 639 886 [Patent Document 6] Japanese Patent Laid-Open No. 2004-332178 [Patent Document 7] Japanese Patent Special Publication No. 7_496〇3 [Summary of the Invention] _ (Problem to be Solved by the Invention) The breast milk pad of Patent Document 6 uses a enamel sheet because the absorbent body is not used, and thus the amount of breast milk absorbed is insufficient, and the shape is due to the deep conical convex shape. Disadvantages of poor performance, when the configuration of the absorber is configured by such a structure, the complexity of the shape of the Ik will not only cause manufacturing difficulties, but also cause the joint to open in use. In addition, the "complex structure of the patent document 7 is a complicated structure in which the elastic body is fixed in the gap and is fixed". In addition to the difficulty in manufacturing, there is also a problem that the elastic body setting portion touches the user's skin, causing hard and uncomfortable stimulation. . 312XP/Invention Manual (Supplement)/96·〇7/96ιΐ4962 200841833 The present invention has been completed to solve such a problem, and aims to provide a relatively easy to manufacture 'smoothness to the user's skin surface with little discomfort and protection A breast milk pad excellent in shape and a method for producing the same.坊' (Means for Solving the Problem) The above object is achieved by applying the invention of claim 1 of the patent scope. Shensun•Patent Range” The breast milk pad of the invention has a backing sheet (five) sheet, an outer liner sheet, and a material for absorbing a volume layer, and the back sheet prevents liquid penetration; The lining is disposed on one side of the body contacting the liquid and has liquid permeability; the liquid disposed between the backing sheet and the outer lining and absorbing and retaining the liquid penetrating through the outer lining; wherein the outer lining The backing sheet is joined to the outer peripheral edge portion, and the outer peripheral edge portion is gradually narrowed toward the inner side in the width of the notch, and the absorbent body is cut to form a notch portion; and the inside of the notch portion is directly or via the absorbent body a thinner sheet is joined to the outer liner and the backing sheet, and each of the notch portions is provided with a joint portion which is folded along the outer surface of the outer liner by the fold line passing through the apex of the notch portion In the state, the inner faces of the overlapping outer lining sheets are joined; in the state in which the product is worn, the extending direction of the fold lines of the joint portion is in a state corresponding to the upper and lower positions. According to the structure of the first aspect of the invention, the absorbent body is accommodated between the outer liner sheet and the backing sheet to form a product. In this case, the outer liner sheet and the backing sheet are joined to the outer peripheral edge portion of the breast milk pad, and the absorbent body is coated with the absorbent body. Not exposed to the outside. Moreover, the absorber located inside forms a special form. In other words, the absorbent body has a notch portion which is formed in a state in which the notch width is gradually reduced toward the inner side from the outer peripheral edge portion, and the absorbent body is cut. 312XP/Invention Manual (Supplement)/96_07/96114962 8 200841833 Thinner sheet and:::: Sheet: inserted or traversed through the mouth of the above-mentioned absorbent body and joined to the apex of the mouth and cross-cut The body: (4) the joint portion, which is overlapped by the above-mentioned lacking port, and the outer lining of the joint is overlapped: the inner yoke overlaps with the outer slab at the position of the notch at the position of the notch portion and is joined to the thicker absorbent body.

[Embodiment] [Brief] For a preferred embodiment of the present invention, reference is made to the accompanying drawings. The embodiment described below is a preferred technical layer (four) of the present invention, which is preferably limited to the following. However, the scope of the present invention is not limited to the premise τ of the present invention. Figure 1 shows a schematic perspective view of the side of the mother's milk in the form of (4) 1 (4), Figure 2 (3) shows a slightly expanded view of Figure i, and Figure 2 (8) shows the folded side of the breast pad shown in Figure i FIG. 3 is a cross-sectional view taken along line A_A of FIG. 3 and a cross-sectional view taken along line BB of FIG. /, 糸图 Referring to the drawings, the structure of the breast pad will be described. The backing sheet 11 is disposed on the outer side (the side of the figure) of the breast pad 10 shown in FIG. 3 and FIG. 4, and is worn when worn, and the outer side (the lower side of FIG. 1) is provided with an outer lining sheet. 13. As shown in Fig. 3 and Fig. 4, the outer lining 13 and the back slab have an absorbent body 12, as shown in Fig. 2(a), and a substantially circular product is disposed between the breast pads 7 and 7 . The 10 series is integrally formed, for example, 312XP/Invention Manual (Supplement)/96-07/96114962 14 200841833 The absorbent body 12 is preferably covered with a tissue 15. Further, an absorption diffusion layer (sublayer) 16 is provided on the outer side of the suction body 12 which is adjacent to the inner side of the outer liner 13 and covered by the base fabric 15. The 11 series does not pass through the material of the liquid. It is best to use a material that can be steamed and can be protected from hot flashes and has a certain degree of flexibility. This sapphire lining 11 is formed by more material than the heat-deformable back sheet used in the prior art. For such a material, for example, a sheet which is not laminated on the outer side of a resin film such as a polycrystalline rubber laminate or a nonwoven fabric, or a non-woven fabric by a melt-blown method, can be used, and the touch is good and the manufacturing is easy. It is preferable to use a laminate material of a non-woven fabric and a resin film. The outer liner sheet 13 is a member that directly contacts the skin of the user, and is made of a material that allows the mother to swell sufficiently moisture and has a good touch. =13Because it directly touches the user's skin, consider the factors that do not cause unnecessary damage to the skin and the feeling of the skin. Then select the appropriate material. It is best to use dry mesh (formed by polyethylene, etc.) The mesh-like sheet), or a non-woven fabric such as a natural fiber such as enamel or a resin fiber such as polyethylene, is preferably a mixture of natural fibers and heat-fusible fibers, from the viewpoint of good touch and easy production. The absorbent body 12 is made of a material having excellent liquid absorbability, and a fibrous body such as paper water, a laminated body, a sheet body, or the like can be used. Further, the absorbent body 12 is preferably mixed in the pulp material or the like. 14. The polymer 14 is a granular material having a good night limb and good retractability and having a function of directly or semi-curing or curing to maintain a liquid function. Such a material constituting the polymer 14 is suitable for, for example, water-absorbent polymerization. , can be 15 200841833 For example: polyacrylate copolymer, house powder - acryl guess graft:: solution: starch-acrylic graft copolymer, polyvinyl alcohol - acrylate /, polymer, carboxymethyl The cellulose modified material, etc. The absorbent body 12 is covered with the base fabric 15 as shown in Fig. 3 and Fig. 4. Thereby, the granular polymer or the like can be prevented from leaking. ★ Fig. 3 does not mean the base fabric! In the attached absorbent body 2, the thick portion 12a' of the dimorphic shape = 21 increases the structure of the sensation of the sensation when the nipple is abutted. In addition, the outer portion of the absorbent body :2: forms a thinner one. The thin portion 12b' constitutes a structure that is attached to the breast. The second thick portion 12a is formed in a curved shape that gradually increases in height toward the center. The condition is applied to the thinner portion 12b after being covered by the base fabric 15. The brakes are thicker and thicker. IM 2a is more compressive and forms different thicknesses, but it can also be laminated. The thicker portion 12a is formed. The absorbing and diffusing layer 16 is disposed at the position of the absorbing body 12, which corresponds to the nipple, as shown by the broken line in Fig. 2(a), and has a lower density than the absorbing body. , 12 ' can increase the initial absorption speed of the liquid, and is a material with excellent diffusibility 'because of lower density' and thus has cushioning property. It is preferable to use fibers having a lower water absorption than the absorbent body 12, for example, alone or in combination. : · 2 Danny to 7·7 Danny around polyethylene, polyester, polypropylene, etc., t into a non-woven fabric, or a continuous foaming sponge, etc. = best in the breast pad 1 〇 backing The outer side of the sheet is provided with a temporary adhesive portion 19 on the underwear such as a bra worn by the user. The adhesive 19 is temporarily adhered to the release paper 19a by adhering the release paper 19a to the adhesive 19b. (Repair)/96·〇7/96ιΐ4962 16 200841833 2 III 2CbM^j Configurable to cover the north and the north. The adhesive portion can be placed in a plurality of parts, and the outer surface of the release paper J is also used. In addition, it can be ignored. : The inner surface of the package 45 to be described later is formed by a peeling place to form a shape of the outer edge position of the outer edge of the package body 45. For example, if the bowl is inverted, the sheet is formed between the approximately convex phase and the second portion (for example, the sheet other than the absorber 12 is joined) (for example, The base fabric and the lining are provided with a thinner than the absorbent body, and the joint portion 21 is formed. The joint portion 21 of the female nipple 10 shown in Fig. i is released. At the time of joining, the suction is opened: as shown in Fig. 122(a), the side opening corresponding to the place where the joint portion 21 is to be formed is formed on the outer peripheral edge portion of the circular product in the shape of the notch width toward the inner side, the side, and the side. The notch portion 22 is formed by cutting the absorbent body 12. The apex of the core end of the notch portion is transverse to the breast milk (4) of the product: the fold line 23, and the outer liner 13 is folded inside, as shown in Fig. 2(b). In Fig. 2(a), the backing sheet and the outer sheet 13+ located on the inner side of each of the notch portions 22 of the absorbent body are lining when the breast milk pad 1 is bent as shown in Fig. 2(b). The sheets 13 are overlapped and folded in half. In the folded state, the outer linings 13 located at the thin portions 22 and facing each other are not connected by the outer lining joint surface 13a as shown in FIG. In this case, the joint portion 2 is formed. At this time, the portion corresponding to the joint portion 21 is not provided with the thick portion 312 of the absorber 12 / the invention specification (supplement) / 96-07/96114962 17 200841833 = and the absorption diffusion layer 16' Rather, the outer lining 13 and the backing sheet f are formed, so that the attachment of the outer lining engaging surface 13a can be easily maintained, and the formed convex shape can be appropriately maintained. The interface is as shown in Fig. 2 (8) The state is unfolded, as shown in Fig. 1, the breast milk pad 10 integrally forms a substantially convex shape energy by the supporting force of the joint portion 21. Preferably, in Fig. 2(b), the backing sheet u and the outer (four) core In the outer peripheral region, a portion corresponding to the notch portion 22 of the absorber 12 is formed to have a truncated portion 24 that is smaller than the notch portion 22. That is, the corner portion of the joint portion 21 is not formed as shown in the figure. The truncated portion 24.° Fig. 5 to Fig. 7 show the detailed structure of the breast pad 1 ,, that is, the enlarged view of the approximately half-region of the nipple of the figure (4) in the folded state. > When the joint portion shown in Fig. 4 is shown in Fig. 4, the outer liner is heat-sealed inside the notch portion 22, and 13 joints are joined. The seal line 25 of the portion is formed in an inclined line shape as shown in the figure. Here, the seal line 25 is located further outside the boundary line 22a of the notch portion 22. That is, the end line of the seal line 25 on the side of the boundary line 22a is folded and folded. The angle b of =23 is larger than the boundary line 22a and the angle (b>a) of the intersection of the yoke and the yoke. In addition, the outer end 25a of the seal line is set to exceed the absorber 12 The outer edge is adjacent to the outer edge of the breast pad 10. Immediately thereafter, the end edge 25b of the seal line 25 and the extension line ' of the boundary of the absorbent body notch portion 22=22a are disposed so as to intersect at the intersection S1, and The ί line 2 5 is arranged such that the closer to the outer end 2 5 a side, the closer to the shape of the absorber 12 and the narrower the distance from the center side of the notch portion 2 2 toward the outer side. Therefore, in the 312XP/inventive book (supplement)/96-07/96114962 18 200841833 after the joint state, as shown in Fig. 9, the side of the side of the breast pad 13 is opened, γ, report, / The breast milk pad 1G, which has a shape of sucking and sucking, is not easy to hold the mouth portion 22, and does not expose the liquid absorbing mouth portion 22, so that the sputum chest can be smashed into the house. % creates a more comfortable feel. Yes, Figure 6 shows that even if the outer edge of the seal line 25 is slightly off the boundary line, then the n9〇M ^ ^... 离 离 界 H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H H The extension is slightly longer toward the side of the absorbent body and, when joined, is joined to the knife. When the breast milk pad 10 is opened as shown in Fig. 9, the joint overlapping portion near the notch 22 is changed to the boundary line 22a. (6) It is not easy to pass out of the notch portion. Further, at the position of the end portion 22c of the notch portion boundary line 22a, if it is from the outside. ^ The side forms a (four) line, which can be surely joined, and the gap corresponding to the above gap W will be less conspicuous. In addition, in order to produce a state similar to a curved convex shape, the k-boundary line 22a of the notch portion is formed in a curved shape which bulges toward the fold line 23, and is formed in a curved shape of the (four) line 25. Thereby, the curved shape of the breast pad 1〇 under the opening and the curved shape of the boundary line with the joint portion 21 as shown in Fig. i can also constitute a structure having approximately the same curved surface. Further, the outer lining sheet 13 is overlapped with the backing sheet 11, and when joined between the outer lining sheets 13 opposed to σ, as shown in Fig. 7, for the extension line 22a of the boundary line 22a of the absorbent body 12, It is preferable that the outer edge portion P1 of the outermost position of the absorber (upper in Fig. 7) is not joined except for the heat seal portion or the seal line. U 2XP/Invention Manual (Supplement)/96-07/96114 points 62 19 200841833 Hunting, for the part indicated by the component symbol pl on the outer circumference of the breast milk pad 10 in Fig. 1, the outer edge portion can be prevented from standing up and causing the use The skin causes uncomfortable irritation. Further, as shown in Figs. 5 to 7, the absorbent body 12 may be cut at a position close to the end portion 22c of the notch portion boundary line 22a to form a substantially triangular-shaped truncated portion 22b. Thereby, the end portion 22c of the boundary line 22a may be joined in a state of being included in the seal line 25-. By forming such a structure, the joined gaps are joined to each other and grounded, so that the absorber is less likely to have a gap, and the effect of liquid leakage is not easy. Fig. 8 shows another forming method of the joint portion. Here, as shown in Fig. 2(b), the illustration of the fusion is shown in Fig. 2, when the breast pad 1 is folded in half and the joint portion 21 is joined, the heating means is used. A partial enlarged view of the joint of the eight and B heat sealers. By the boundary portion 34 as a boundary, the strong fusion portion 33 between the lower side of the heating means a having a relatively narrow interval a: 37 and the upward facing surface of the heating means B is sandwiched between the outer liner 13 and the back. The linings are overlapped with each other: should be, the joint portion 21 towel. At the same time, the thicker side is provided with a thicker region of the absorption-thickness, which is inserted into the step 38 of the heating means with a wider interval, and the stepped portion of the heating means In section 32, add & pressurize. Β < weakly melting, the joint portion 21 which is pressed by the notch portion 22 in which the outer lining sheet 13 and the backing sheet η are overlapped, is arranged in such a manner as to interpose the absorber 12, and is used by the weak 312 ΧΡ / flip instructions (supplement) /96-07/96114962 20 200841833 The worm's joint part 3 2 is sealed from the wide & user's skin sounder: the area covered 'to prevent not only touching the user's skin Uncomfortable stimulation can also prevent damage to the material of the outer edge due to unnecessary (4) injury. However, although a weak fusion portion is formed which is heat-sealed by providing the absorber 12, as shown in FIG. 5 or FIG. 6, the strong fusion portion 33 can be formed by forming the seal line 2. It can also be seen as a rainbow of the long-term fusion parts 32, 33. Line poison

Further, the outer lining 13 is thermally fused, but the joint portion 21 may be formed using an adhesive such as hot melt adhesive at the position of the joint portion 21, and the heat fused joint may be used at a position such as the body. In the unreceived position, an adhesive or the like is used in combination, and a combination of heat fusion and an adhesive is used. Fig. 9 is a view showing a fiber alignment direction of the nonwoven fabric forming the outer liner 13 in a state in which the breast pad is unfolded and used on the outer liner side. The outer liner sheet 13 of the breast pad 10 is preferably integrated with the fibers constituting the outer liner 13 in a direction K2 which is approximately orthogonal to the direction in which the breast milk pad 1 is folded (i.e., 90 degrees intersect). Therefore, when the product is worn in the direction in which the folding line 23 extends in the vertical direction, the alignment of the fibers is perpendicular to the vertical direction of the body, and the breast milk can be appropriately prevented from being aligned along the fibers (especially the lower side). Further, in the approximate central region of the absorber 12 shown by the broken line, the joint portion 21 is joined and deformed so as not to be exposed inside the notch portion 22 on the body side, and a slightly rounded shape as indicated by a broken line is formed. Thick portion 12a. 312XP/Invention Manual (Supplement)/96-07/961 M962 21 200841833 Figure 10 is a diagram showing a variation of the portion shown in the cross-sectional view taken along line BB in Figure 1. As shown in Figure 10, The absorbing diffusion layer 16 is interposed in the joint portion 21, and the absorbing layer of the absorbing diffusion layer 16 is present in the notch portion 22 of the absorber 12, so that the touch to the user's skin can be made better, and the wear can be improved. In the present embodiment, the above-described respective joint portions 21 of the breast milk pad 0 overlap the outer liner sheet 13 and the backing sheet U, and the absorbent body 12 is notched between the opposing outer liner sheets 13. The joint surface 3a in the portion 22 is joined and thus absorbed In other words, it is possible to manufacture relatively easily without overlapping and joining between the thick absorbent bodies 12, and it is also possible to prevent the joint from falling off. Further, since it is not joined to the absorbent body 12, it is made. Since the shape of the convex surface is absorbed by the absorber 12, even if the absorber 12 is planarized, the outer portion of the joint portion 21 of the convex shape of the branch does not change, so that the shape of the convex surface does not collapse extremely. And the tenth 〇 、 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , The shape is not formed by the use of pleats as is the case with common practices. Therefore, it is not necessary to elasticize the rubber.

It can make manufacturing easier. In particular, when the inner portion P is formed into the joint portion 21, it is configured to have a structure of 13 Λ and a fused material, as shown in item 2 (b), at the time of folding, by 312 ΧΡ / SUMMARY OF THE INVENTION (Supplement) /96-07/96114962 22 200841833 The joint portion 2 can be formed by heating and melting from the side of the backing sheet 11, whereby the joint of the shape of the support convex can be formed only by the heat sealing step. Department 3. Further, since the adhesive is not used for the bonding, the foreign body sensation at the time of wearing is not caused by the application of a predetermined amount of the adhesive or the like. In addition, as shown in FIG. 1, when the joint portion 21 is cut at a truncated angle and the truncated portion 24 is provided, when the breast milk nipple 1 is worn inside the underwear as described later, even if the corner portion abuts against the inner surface of the underwear such as a bra, Reversing toward the side of the body does not constitute a cause of discomfort. Here, although only the corner portion of the truncated portion 24 is slightly cut, the portion 21 may be cut to a larger truncation angle in the range in which the joint portion 21 is ensured to be joined, or the joint portion 21 may be cut. More truncated portions 24. Further, this embodiment is a structure in which the product is folded in a folded state by a fold line 23 as shown in Fig. 2(a). Therefore, as will be described later, when the breast milk pad 10 is stored in a packaging means or the like, the state of the folded plane in which the pair is folded is not only reduced in thickness during storage, but also does not damage the shape of the support convex shape due to the storage form. Since the two ISs are opened from this state, the convex shape can be easily seen, and thus it is simple to use. Further, in the present embodiment, the outer joint portion 21 (the notched portion 22) of the breast milk is placed at one side. The function in which the joint portion 21 or the notch portion 22 is formed is formed by the formation of the outer portion, and the overall shape is formed into a convex shape, and a plurality of layers can be formed by ::. That is, the joint portion 21 or the notch portion is increased by 'and each size is made smaller, whereby a uniform and beautiful convex shape can be obtained by the 312XP/invention specification (supplement)/96-07/96114962 23 200841833. However, the portion where the joint portion 21 is formed forms an uneven surface, and when worn, the user touches the skin of the user or hooks the portion of the underwear, which may result in damage to the wearing feeling. In the present embodiment, in order to prevent the occurrence of such a situation, in particular, only one joint portion 21 (notch portion 22) is formed, and the joint portion 21 is disposed as described later to form a wearable state. Fig. 11 is a schematic perspective view showing a second embodiment. In the second embodiment, the same components as those of the breast pad shown in Fig. 2 are denoted by the same reference numerals, and the description thereof will not be repeated, and only the differences will be mainly described below. The breast pad 1 is at the outer edge portion, and the outer liner 13 and the sheet 11 and/or the absorbent body in the laminated material are removed to form the outer edge cutting portion 41. The outer edge cut σ卩41 is a curved portion in which the upper curved portion is convexly formed outside the circular product to form an inclined straight line or a convex portion that protrudes toward the inner side. σ • Thereby, as shown in FIG. 12, for example, in the case where the breast milk pad 10-1 is housed in the cup portion BC of the bra, the outer edge cutting portion of the breast pad 1〇_丨 is placed on the cup portion BC. Near the edge, completely hidden inside. As a result, the breast milk pad 1 〇 -1 is not easily exposed from the cup portion B C and is perceived to be worn 9 , and can be used integrally with the bra B to reduce discomfort. Further, although the other edge trimming portions 41 and 41 are formed at two locations, they may be provided with left and right directivity at one inner portion corresponding to each of the cups. Mouth Photograph 13. Fig. 13 shows a breast pad 1 〇-; [Figure with the breast of the user, which is an explanatory view of the sternal shape of the breast UB and the lanthanum between the breast pad 31114962 24 200841833. As shown in Fig. 12, when the breast milk is called in the inner side of the bra 6 of the underwear, the joint portion is accommodated. (The direction in which the fold line 23 extends) is located on the lower side of the user's body. The fold line 23 extends in the up and down direction. According to this tooth wear, there are mainly two advantages. First, the fold line 23 is formed in the longitudinal direction to improve the mother rigidity 'at the time of breastfeeding' to prevent the death of the garden meat. / ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( The influence of the operation such as the upper and lower jaws causes the breast milk pad 10-1 to be prone to longitudinal, bending, etc., and the injury occurs. Knife private gas: 3⁄4 loss The second line enhances the conformity. Figure 13 The 'larger breast υβ' has the features of Figure *. Namely, the milk UB forms a sharp bend at the lower end of the three-dimensional shape, and a smooth curve on the upper side. In other words, the figure indicating the shape of the breast υβ is “the size η of the nipple at the upper end of the courtroom, which is larger than the size Τ2 of the nipple from the lower end of the breast. The breast milk of the present embodiment is 1 (the Μ can be appropriately applied to cover such a The three-dimensional shape of the breast UB. ☆ In other words, the joint portion 21 (i.e., the notch portion 22 for forming it) is located under the breast pad 10 1 . The joint portion 2 ^ is smaller than the size of the portion of the breast milk 10 - 1 And the portion is made to be more strongly curved by the formation, so that the shape shown by the lower end of the breast UB can be easily bent. Therefore, the breast pad 10-1 places the joint portion 21 in the longitudinal direction, particularly when the joint portion When the number of 21 is one, the joint portion 21 is disposed at the lower end in the vertical direction as shown in Fig. 12 and Fig. 13 and is more appropriately applied. The positional deviation is less likely to occur. 312XP/Invention Manual (supplement)/96·〇 7/96114962 25 200841833 Here, as shown in FIG. 13, it is preferable that the notch portion for forming the joint portion 21 is set to a size h2 between the outer peripheral edge portion of the breast pad 10-1 and the apex of the notch portion 22, in mutual The size of the connecting line between the opposite outer peripheral portions ( The size h3 of the 1/2 of the total length (hl+h2) of the fold line 23 is equal to or less than this. As shown in the figure, since the position where the joint portion 21 (the notch portion 22) exists is shifted downward from the periphery of the user's nipple, Therefore, when the breast milk pad 10-1 is worn, the joint portion 21 (the notch portion 22) can be effectively prevented from hitting a sensitive region such as a nipple or a areola, and the wearing feeling can be improved. Fig. 14 is a third embodiment. In the embodiment, since the breast pad 1()_2 is not provided with the outer edge cutting portion 4, it has almost the same structure as the jth embodiment described in Fig. 3. The difference is that the pair is formed in the breast milk. The lower end means _2 is the horizontal cutting portion 26 which becomes the horizontal cut portion. Further, the 'horizontal cutting portion 26 forms the flat end face of the lower end of the female nipple 12. Thereby, the user does not form the breast milk 塾 1G_2 Under the outer edge cutting section, the wearing direction can still be easily recognized, and the middle bra B is substantially flat underneath: and: (4) 26 pairs can be used to put the breast milk pad 1〇-2 in the correct orientation (direction). It is said that it is really apt to wear. ~ Can be like another, when, also The breast cutting pad 1Q-2 is simultaneously formed with the horizontal cutting portion 26. The male part (the manufacturing method of the breast pad) 312XP / invention manual (supplement) / 96-07/96114962 26 200841833 Second, the manufacturing method for the breast milk In the manufacturing apparatus which is not shown, a reversing production line such as a carousel is provided, and the manufacturing process proceeds along the moving direction and further in the K1 direction. Forming step) In Fig. 15, first, the base fabric 15 is fed in the form of a strip material at the beginning of the conveyance line, from the supply reel of no =. The base transfer line feeds in the direction of arrow K1. Then, a pulp supply means (not shown) is disposed at the center of the transfer fabric 2, and the pulp is supplied with the pulverized pulp. The notch width is gradually reduced toward the inner side to form a notch 胄 22), and the base fabric 15 is folded back toward the inner side by the folding plate, and is used to cover the base fabric 15 and covered with pulp. The absorber 12 forms an absorber body. In the case of Fig. 16, the adjacent portions of the product units which are adjacent to each other and which are slightly rounded are integrally connected to each other to form a continuous continuous state (hereinafter referred to as "continuous absorber 12-1"). Next, as shown in FIG. 17, in order to form a continuous body of a slightly rounded edge of the continuous absorbent body 12-1' S covered by the base fabric J 5, and slightly outside the outer edge of the outer absorbent body The dotted line C1 cuts the base fabric 15 to correspond to the circular shape and size of each product. After that, in the stage of FIG. 16, the absorbing body C3 is applied from the upper and lower sides to the thicker portion 12a so that the outer peripheral pressure is larger than the central portion of the absorbent body. The outer peripheral portion is compressed into a thinner portion 312XP/invention specification (supplement)/96-07/96114962 27 200841833 12b. Thereby, the base fabric 15 and the absorber 12-1 can be reliably integrated. Next, as shown in Fig. 18, 'the continuous absorbent body is called at the position of the cut portion C2 corresponding to each product, and is cut by a diagonal knife to obtain the absorber 12 in the negative and negative steps. The coated absorbent body is wrapped between the outer liner and the backing sheet. & In addition, the substrate 1 is folded to form a coated absorbent body. The base fabric 15 can be formed by using two base fabrics 15 to be sandwiched from the upper and lower sides. The notch portion 22 of the shingling spring 12-1 is formed by the suction molding drum = 'preliminarily formed into an absorbent body having the shape of the notch portion 22, and is disposed on the base L, but can be formed, for example, by repeated cutting. Alternatively, the two-layered absorber 12 may be formed by a non-shaped roller or the like, and the thicker portion (5) may be formed by the outer sheet of the surface material as shown in FIG. 19, and the second layer: / / (4) A non-woven fabric composed of a mesh sheet formed of polyethylene or the like is supplied, for example, by a belt-shaped cut-off non-woven fabric.攸 VII, should be shipped with the same volume and along the direction of transport Κ 1 smelting and other components 丨 3-1 above 'pre-coated rubber or olefin system 荨 荨 者 ( 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定 固定The positive side corresponds to the next I 16 of the Μ or the moment material collecting and diffusing layer of each product, and the gossip is integrally transported. Further, as shown in Fig. 20, a backing sheet u is formed, and a supply reel 312XP (inventive manual _6-_6114962 28 200841833) which is not illustrated is laminated on a resin film such as polyethylene, and the polyethylene laminate is not stretched = resin The sheet formed on the outer side of the film or the pattern formed by the marshalling method is not: η], for example, a continuous strip-shaped material of a laminate of a non-woven fabric and a resin film, and is fed in the conveyance direction K1. In the strip material, on the peeling surface of the release paper, the "adhesive preventing offset, the release paper" 9a is cut into the area of the product unit along the area indicated by the dotted line on the right side. (Laminating step and sealing step) = ^ The absorbent body 12' shown in Fig. 18 is sandwiched between the appearance sheet shown in Fig. 19: between the member piece 13-1 and the backing sheet strip-shaped structure 1H to which the adhesive is previously applied. 'For the outer peripheral region of the absorbent body 12 and the notch portion μ, = and fix the strip member of the backing sheet strip member and the outer liner sheet, and the outer liner sheet η and the backing sheet 13 are sandwiched with the absorbent body 12 of the 12 fixed.
