Although it is expressed in a defined strip shape, it is actually a strip-shaped material in a predetermined direction, and is stored in, for example, a roll form at the material supply location of the process, which is used for the progress of the process. In addition, the material is fed out in a predetermined direction and conveyed in a predetermined direction. In this example and the description after the second embodiment, the constituent members used in the manufacturing process are continuously in a predetermined direction as in the case of the nonwoven fabric 2 and the liquid-impermeable sheet 3 unless otherwise specified. It is assumed that the material is a long belt-like material.

 As shown in FIG. 2, a plurality of absorbent bodies 4 having a width smaller than that of the liquid-impermeable sheet 3 are placed on the central portion in the width direction of the liquid-impermeable sheet 3 at appropriate intervals in a predetermined direction. Arrange. The type of the absorber 4 is not particularly limited, but if a component other than the liquid absorbent material itself, for example, a top sheet or an AQL (Aquisiti on Layer) to be put on the liquid absorbent material is necessary, these are preliminarily provided. Depending on the function and structure of the absorbent body 4 required by the specifications of this absorbent product 1a, such as supplying the combined product or superimposing these components on the absorbent body 4 in the process (not shown) It shall correspond.

As shown in Fig. 3, one boundary part in the width direction of the laminated nonwoven fabric 2 and liquid impervious sheet 3, that is, continuous in a predetermined direction in which the nonwoven fabric 2 and liquid impervious sheet 3 are adjacent in the width direction. A plurality of elastic members 5 are respectively arranged in two regions in a state where they are extended in a predetermined direction. A polyurethane filament or the like can be used as the elastic member 5. Since the leg hole 6 is formed at the boundary between the nonwoven fabric 2 and the liquid impervious sheet 3 in a later step, there is room for forming the leg hole 6 without cutting the elastic member 5 and the leg hole. A portion having _a relatively wide space _a is provided in the space between the elastic members 5 so that the elastic members 5 are arranged on both sides of the 6. Here, the interval a is between the elastic member 5 provided on the nonwoven fabric 2 and the elastic member 5 provided on the liquid-impermeable sheet 3. It is.

 As shown in FIG. 4, both side edges in the width direction of the non-woven fabric 2 are folded inward, and are bonded with the elastic member 5 interposed therebetween.

 As shown in FIG. 5, in one boundary region on the rain side of the absorber 4, a leg hole 6 is formed in a slit-shaped opening along a predetermined direction at a position where the distance between the elastic members 5 is a wide. As a through-hole. As a result, the elastic member 5 is arranged above and below the leg hole 6 (left and right in the figure), and when worn, the entire circumference of the leg hole 6 is elastically adhered to the circumference of the wearer's leg, so that the absorbent product 1 a The sealed state can be maintained.

 As shown in Fig. 6, the absorbent body 4 is folded in two along the center line parallel to the predetermined direction, passing through the center of the absorbent body 4 in the width direction, and the both edges in the width direction of the nonwoven fabric 1 overlap. Wrap the whole thing.

 As shown by the chain line in Fig. 7 (a), the absorbent product 1 shown in Fig. 7 (b) is sealed by sealing between the absorber 4 and the absorber 4 along the direction orthogonal to the predetermined direction. separated into a. The shape of the absorbent product 1a shown in Fig. 7 (b) represents the individual product of the moment when the seal is cut while being stretched by applying tension in a predetermined direction as shown in Fig. 7 (a). In fact, at the moment when the seal is cut and separated into individual products, the elastic member 5 is retracted, so that the upper part of the leg hole 6 (the body part 7 described later) as shown in FIG. ) Is shrunk, and the part below the leg hole 6 (a bag part 8 to be described later) is relatively extended in the front-rear direction.

Thus, according to the manufacturing method of the absorbent product 1a of the present example, the belt-shaped nonwoven fabric 2 and the liquid-impermeable sheet 3 are stacked and conveyed in the horizontal direction, and the absorbent body 4 is placed thereon at a predetermined interval. Arrangement The elastic member 5 stretched in the same conveying direction is placed, and the whole is folded in half along the center line parallel to the conveying direction, and the individual absorbers are absorbed by sealing seals between the absorbent bodies 4 and 4 one after another. Since it can be separated into the body product 1a, the absorbent product 1a can be easily and reliably mass-produced.

 In the manufacturing method of this example, the left and right leg holes 6, 6 were separately formed as shown in FIG. 5 (a). However, after the whole was folded in the process shown in FIG. Then, the left and right leg holes 6, 6 may be collectively formed by cutting.

 (2) Structure (Fig. 8 to Fig. 11)

 Next, the structure of the absorbent product 1a obtained by the above steps will be described with reference to FIGS. 8 to 9 show the form of the absorbent product 1a of this example when it is spread out as if it was worn on a human body. First, the body part 7 is a circumferential part composed of the nonwoven fabric 2 with the elastic member 5 interposed therebetween, and has a waste hole 9 penetrating vertically, and is elastically adhered to the waist of the wearer. Installed.

 The bag portion 8 integrally formed on the lower side of the body portion 7 includes a bag body 1 1 communicating with the lower opening of the waste hole 9 of the body portion 7 through the upper opening 10, and an inside of the bag body 1 1. Consists of 4 stored absorbers. The bag body 1 1 is composed of a leak-proof body composed of an outer nonwoven fabric 1 and an inner liquid impermeable sheet 3, and the absorbent body 4 is arranged at the bottom of the bag body 1 1 along the inner surface of the bag body 1 1. It has been done. A leg hole portion in which a leg hole 6 is opened is formed at each boundary portion of the rain side surface of the body portion 7 and the bag portion 8.

Therefore, the torso part 7 and the bag part 8 are arranged at the front center corresponding to the wearer's abdomen and the rear part corresponding to the wearer's back, except for the bottom part of the bag part 8 that is folded back along the center line along the wearer's longitudinal direction. Center Are joined to each other.

 When wearing the absorbent product 1 a having such a structure, the wearer puts both legs into the body part 7 from the waist hole 9 and then protrudes from the inside of the leg hole 6 to the outside, lifting the body part 7 and lifting the waist part. Attach around.

 In such a wearing state, the bag part 8 in which the absorbent body 4 is housed is suspended from the body part 7 between the wearer's legs, and is passed from the front lower abdomen of the wearer through the mouth opening part. The part involved in excretion of urine and stool reaching the lower back is in a state facing the upper opening 10 of the bag body 11. In other words, the ejector and the position where the absorber is present are separated. Most of the urine and feces excreted from the wearer can enter the bag portion 8 through the upper opening 10 without contacting the body surface of the wearer.

 According to the conventional absorber product, the absorber is placed in close contact with the body surface, and the urine that flows between the body surface and the absorber is absorbed and absorbed by the absorber. The total amount is difficult to use efficiently, the skin may be irritated by urine, and the feeling of wearing was not good, but according to the absorbent product 1a of this example, the urine and feces excreted by the wearer are worn by the wearer The urine etc. easily move inside the bag body 1 1 and is efficiently absorbed by the internal absorbent body 4. In addition, since the absorbent body 4 is placed in the bag body 11 and is always away from the body surface of the wearer, urine does not stay between the absorbent body 4 and the skin, and the skin is covered with urine. There is little fear. In addition, the feeling of wearing is also good. In addition, since the elastic member 5 is provided below the body portion 7 and the leg hole 6, high adhesion is obtained at the portion that comes into contact with the human body, and liquid leakage and odor leakage are prevented.

In addition, as shown in FIG. 7 (b), the leg hole 6 in this example is connected to the back joint and the abdomen. Since it is formed slightly from the abdomen rather than the center of the joint, the volume for storing feces is large. Also, if the leg hole 6 is formed in the center of the back joint and the abdominal joint to make the front and back the same shape, there is no distinction between the front and back, and it can be worn without checking the front and back. In addition, if the leg hole 6 is formed so as to be inclined from the back to the abdomen with respect to the upper edge of the body part 7, the abdomen side of the bag part 8 is lowered when worn, and urine is stored in the bag part 8. Easily guided to the front, conversely, if the leg hole 6 is tilted so as to descend from the back toward the abdomen, the back side of the bag 8 is lowered when worn, and urine is guided to the back of the bag 8 Since it becomes easy, it is possible to set urine easily in an appropriate part of the bag body 11 according to the expected position of the wearer.

 In addition, as shown in FIG. 7 (b), the leg hole 6 in this example is formed as a slit-like opening (a linear opening), but the opening shape is a horizontally long rectangle or an ellipse or other horizontally long shape. Thus, it may be formed as a notch-shaped opening having an opening area larger than that of the slit. In this way, a notch-shaped opening with a large opening area makes it easier to put on the wearer's leg when wearing it, but the wearing operation becomes easier, but on the other hand, the airtightness is lowered.

 Fig. 10 is a perspective view showing the above-described absorbent product of the present example in an expanded state. Fig. 11 (a) is a diagram showing a state in which an infant is wearing the absorbent product of this example. FIG. 2B is a front view showing the part in a transparent manner, and FIG.

 (3) Modifications (Fig. 12 to Fig. 17)

A modification of the structure of the absorbent body 4 and the like in the absorbent body product 1a of this example will be described. Fig. 1 2 and Fig. 1 3 show a plurality of types of modifications using a sheet-like absorbent body 4 mainly composed of SAP as the absorbent body. A vertical plane perpendicular to the wearer's front-rear direction is cut. FIG. In this modification, two sheet-like absorbent bodies 4 are formed into a bag body. In the vicinity of the upper opening 10 of the 1 1, each upper edge is connected to each inner surface of the both sides of the bag body 1 1 so as to protrude downward and inward. A space having a height L is formed between the lower end of the sheet-like absorbent body 4 and the bottom of the bag body 11, and a gap 12 connecting the space above the sheet-like absorbent body 4 and the space is absorbed in the sheet form. Formed at the lower end of the body 4. Such a space plays a very important role for absorbers based on SAP. In other words, it takes a certain time to start swelling absorption of SAP, so a function to temporarily store urine is required. The present inventors refer to this as a trap function, but this space is for exhibiting such a function. The height L of the space between the lower end of the sheet-like absorbent body 4 and the bottom of the bag body 11 achieves the trap function in the same space as well as the purpose of moving urine and storing stool more effectively. For this purpose, for example, it is preferable that the thickness is 5 mm or more. More preferably, it is 10 mm to 30 mm.

 According to the modification of FIG. 12 (a), two sheet-like absorbers 4 having different lateral dimensions are extended obliquely downward, and both lower end portions are overlapped with a gap 12 therebetween. . According to the modification of FIG. 1 2 (b), two sheet-like absorbers 4 having the same lateral dimensions are extended obliquely downward, and both lower end portions face each other with a gap 12 between them. Are arranged as follows. According to the modification shown in FIG. 13 (a), two sheet-like absorbent bodies 4 that are folded to have a substantially triangular cross section are extended obliquely downward, with both lower end portions having a gap 12 between them. It is installed so as to face each other. According to the modification of FIG. 13 (b), one sheet-like absorbent body 4 having a curved shape (substantially U-shaped in cross section) along the inner surface of the bag body 1 1 is formed on the inner surface of the bag body 11. As shown in FIG. 13 (c), a notch-like gap 12 like a substantially elliptical shape is provided at its lower end.

According to each modification shown in FIGS. 12 and 13, urine is lowered along the sheet-like absorber 4 To the lower space from the gap 1 2 and then freely move back and forth in the lower space in the bag 1 1 to efficiently transfer the entire amount of the sheet-like absorbent 4 in the bag 1 1 Used to absorb. Further, dropping the stool from the gap between the sheet-like absorbent bodies 4 into the lower space also has an effect of holding the stool away from the wearer's body surface. The sheet-like absorber 4 may be either a type that absorbs from the front side or a type that absorbs from the back side.

 14 and 15 show a plurality of types of modifications in which a liquid guide sheet 13 or the like is provided between the absorbent body 4 and the bag body 11. Fig. 14 (a), Fig. 14 (c), Fig. 15 (a) are longitudinal sectional views of the bag portion 8 with the vertical plane orthogonal to the wearer's front-rear direction as the cut surface. (b) is a partially enlarged view of Fig. 14 (a), and 园 15 (b) is a diagram showing the unfolded state of Fig. 15 (a).

FIG. 14 According to the modification shown in FIGS. 4 (a) and (b), a liquid guide sheet is formed between the absorbent body 4 shaped along the inner surface of the bottom of the bag body 11 and the bottom of the bag body 11. 1 3 is arranged. As shown in Fig. 14 (b), the absorbent body 4 of this modification is an absorbent body 4 in which a top sheet 15 is affixed to a pulp and SAP mixture pine 14, and a liquid guide sheet 13 is It consists of a hydrophilic nonwoven fabric such as TCF. In the modification shown in FIG. 14 (c), the absorbent body is a sheet-like absorbent body 4, and a liquid guide sheet 13 is provided between the sheet-like absorbent body 4 and the bag body 11. In addition, both side edges of the sheet-like absorbent body 4 are flanges 16 that are folded inward of the bag body 11, so that the body fluid stored in the bag section 8 is difficult to leak to the outside. According to these modified examples, the wearer's urine discharged into the bag portion 8 is guided between the bag body 11 and the absorbent body 4 by the liquid guide sheet 13 and diffuses and moves. Can be absorbed effectively. According to the modification shown in FIGS. 15 (a) and (b), two sheet-like absorbent bodies 4, 4 are provided on the inner surfaces of both sides of the bag body 11, and are formed on the bottom of the bag body 11. A gap that continues in the longitudinal direction along It is arranged with a gap. A liquid guide sheet 1 3 is provided between the sheet-like absorbent body 4 and the bag body 1 1, and a spacer member such as an opening film is provided between the liquid guide sheet 13 and the sheet-like absorbent body 1 7. Is provided. According to this modification, the space between the bag body 11 and the absorbent body 4 is expanded by the spacer member 17 and the movement of the liquid becomes easier, so that the urine is diffused by the liquid guide sheet 13. The moving action is further promoted, and urine can be absorbed more efficiently by using the entire amount of the absorbent body 4 in the bag body 11.

 FIGS. 16 and 17 show a modification of the arrangement of the absorbent body 4 at the front and rear of the bag body 11, and each partial view (a) is orthogonal to the wearer's front-rear direction. It is a longitudinal cross-sectional view of the bag part 8 with a vertical plane as a cut surface. Each partial view (b) is a plan view of the absorber 4 at the front, and each partial view (c) is a plan view of the absorber 4 at the rear. is there.

 According to the modification shown in Fig. 16, the absorbent body 4 is arranged in a V-shape along the inner surface of the bag body 11, and there is no hole slit in the front part, but in the rear part. A slit-like gap 11 is formed for dropping the stool downward. According to the modification shown in Fig. 1 (b), two planar absorbent bodies 4 and 4 are arranged along the inner surfaces of both side portions of the bag body 11 at intervals, and both absorbent bodies are disposed at the front portion. 4 are connected by a liquid-permeable nonwoven fabric 18, and in the rear part, a gap 12 is left between the absorbent bodies 4, 4 in order to drop feces downward.

 According to the modifications shown in FIGS. 16 and 17, the stool is dropped downward from the gap 12 provided at the bottom of the rear part of the absorbent body 4 to enter the space between the absorbent body 4 and the bag body 11. Can be stored and held.

 (4) Removal method of absorbent product 1a

To remove the absorbent product 1a in this example from the wearer's body, reverse the wearing operation. However, the body part 7 above the leg hole 6 and the bag part 8 below the leg hole 6 are separated from each other in the wearing state, and the body part is removed after the bag part 8 is removed. 7 can be removed from the wearer's waist. Alternatively, the joint portions at the front center and the rear center of the body part 7 and the bag part 8 can be cut left and right and removed from the lower body of the wearer.

Tissue 19 is an example of a liquid-permeable sheet, and is not limited to only a tissue, but is a sheet made of a material having liquid permeability such as rayon nonwoven fabric, TCF, and hydrophilic spunbond. Can be used without any particular restrictions. The type of the absorbent body 4 is not particularly limited, but if a component other than the liquid absorbent material itself, for example, a top sheet AQL to be put on the liquid absorbent material is necessary, these are combined in advance. This absorber product 1 b, such as by supplying these components to the absorber 4 in the process, although not shown, Corresponding to the function and structure of the absorber 4 required by the specifications. As shown in Fig. 20 (a) and (b), both side edges in the width direction of the absorbent body 4 are folded inward, and are shown by chain lines so as to have an appropriate length in a predetermined direction as shown in Fig. 21. By cutting in the width direction along the cutting line, a plurality of absorbent bodies 4 each having a flange portion 16 for preventing liquid backflow are manufactured.

 As shown in FIG. 12, the absorbent body 4 having a width smaller than that of the liquid-impermeable sheet 3 is placed on the central portion in the width direction of the strip-shaped liquid-impermeable sheet cage 3 that is continuous in a predetermined direction. Arrange them at appropriate intervals in a given direction.

 As shown in FIG. 23, while the belt-like nonwoven fabric 2 continuous in a predetermined direction is continuously supplied and conveyed in a predetermined direction, the absorbent 4 is disposed in the center of the nonwoven fabric 2 in the width direction at a predetermined position. Supply impermeable sheet 3 and superimpose and continuously bond.

 As shown in FIG. 24, one or more elastic members 5 (for example, polyurethane filaments) are respectively arranged on both side edges in the width direction of the nonwoven fabric 1 while being stretched in a predetermined direction.

 As shown in FIG. 25, the rain side ridges in the width direction of the nonwoven fabric 2 are folded back inward, overlapped with the elastic member 5, and the nonwoven fabrics 2 are bonded to each other. This portion is provided in the upper opening 10 of the bag body 11 and is formed so as to protrude into the upper opening 10, and an elastic band 20 that prevents body fluid from leaking out of the bag body 11. Become.

As shown in FIG. 26, two boundary portions in the width direction of the laminated nonwoven fabric 2 and the liquid impermeable sheet 3 are overlapped, that is, in a predetermined direction in which the nonwoven fabric 2 and the liquid impermeable sheet 3 are adjacent to each other in the width direction. A plurality of elastic members 5 are respectively arranged in two continuous regions in a state where they are stretched in a predetermined direction. The boundary between the non-woven fabric 2 and the liquid-impermeable sheet 3 is recorded at a later stage. Since the leg hole 6 is formed, there is room for the leg hole 6 to be formed without cutting the elastic member 5, and the elastic member 5 is disposed on both sides of the leg hole 6 as in the first embodiment. A portion having a relatively wide space a is provided in the space between the members 5. As shown in FIG. 27, both side edges in the width direction of the non-woven fabric 2 are folded inward, and the elastic member 5 of the elastic member 5 is sandwiched and bonded.

 As shown in Fig. 18, in the two boundary regions on both sides of the absorber 4, the leg hole 6 is slit-shaped along the predetermined direction at the position where the distance between the elastic members 5 is a wide. As a through-hole. As a result, the elastic members 5 are arranged above and below the leg hole 6, and when worn, the entire circumference of the leg hole 6 adheres elastically to the circumference of the wearer's leg, so that it is sealed as an absorbent product 1b. Can keep the state. Also, as shown in FIG. 28 (a), a short stop cut in a direction perpendicular to the slit is formed at both ends of the leg hole 6 in order to prevent further progress of slit-like rifts forming the leg hole 6.卜 2 1 shall be provided.

 As shown in Fig. 29, the absorbent body 4 is folded in two along the center line parallel to the predetermined direction through the center of the absorbent body 4 in the width direction, and both side edges of the nonwoven fabric 1 are overlapped. Wrap the whole thing.

As indicated by the chain line in FIG. 30 (a), an absorber as shown in FIG. 30 (b) is obtained by sealing between the absorber 4 and the absorber 4 along the direction orthogonal to the predetermined direction. Separated into product 1b. The shape of the absorbent product 1 b shown in FIG. 30 (b) is the individual shape at the moment when the sealing force is applied in the stretched state with tension applied in a predetermined direction as shown in FIG. 30 (a). It represents the product of, and in fact, the seal cutlet At the moment of separation, the body part 7 above the leg hole 6 contracts as shown in FIG. 3 1 (a) due to the contraction of the elastic member 5, and the bag part 8 below the leg hole 6 relatively moves. The outer shape is projected back and forth.

 (2) Structure (FIGS. 31 to 33)-Next, the structure of the absorbent product 1b obtained by the above steps will be described with reference to FIGS. 31 to 33. Fig. 31 and Fig. 32 show the form when the absorbent product 1b of this example is spread as if it was worn on the human body. Fig. 33 is a schematic front sectional view of the bag 11 of the absorbent product 1b of this example.

 The absorbent product 1b of this example has the same structure as the absorbent product 1a of the first embodiment described with reference to FIGS. 8 and 9, and as shown in FIGS. 3 2 and 33. It has an elastic band that protrudes inward from both sides. This stretchable band includes a stretchable band 20 composed of a leg portion made of nonwoven fabric 2 projecting from each inner surface of the bag body 11 and an elastic member 5 provided at the tip of the leg portion. The elastic band 20 extends inward and upward on the inner surface of the upper opening 10 of the bag body 1 1 and contacts the body surface of the wearer, so it is discharged into the bag body 11. Thus, it is possible to prevent the body fluid collected in the absorber 4 from flowing out to the wearer's body surface again due to gravity and leaking outside. In addition, the absorbent product lb of this example is a bag 1 1 in which the upper collar portion of the sheet-like absorber 4 in the vicinity of the upper opening 10 of the bag body 1 1 is folded inward of the bag body 1 1. Therefore, the body fluid to be leaked to the outside can be prevented from being leaked to the outside by being absorbed by the buttocks 16 near the upper opening 10.

 (3) Other structural examples (Fig. 34 to Fig. 36)

The absorbent product 1b of this example is obtained by providing the absorbent product 1a of the first embodiment with the stretchable band 20 and the flange 16 of the absorbent body 4. The buttocks 1 6 are explained below As such, each may be provided alone.

 That is, as shown in FIG. 3 4 (a), an absorbent body 4 (not necessarily a sheet-shaped absorbent body) is provided at the bottom inside the bag body 1 1, and the upper opening 1 of the bag body 1 1. If a pair of stretchable bands 10 made of a nonwoven fabric 2 and an elastic member 5 are provided on the inner surface close to 0, facing the inner side downward, the inner surface of the bag body 11 is located below the elastic band 20 A pocket-shaped receiving space is formed between them. Therefore, even if the wearer changes his / her position and the urine in the bag body 11 flows backward from the upper opening 10, the urine does not enter the receiving space and directly flow out.

 Note that FIG. 34 (b) is an example of a structure in which the stretchable band 20 is provided inward and upward, and has the same configuration as that of FIG. 32 and FIG.

 Fig. 35 (a) shows an example in which the upper collar part of the sheet-like absorbent body 4 near the upper opening 10 of the bag body 11 is folded inward to form the collar part 16; ) Is an enlarged view of the sheet-shaped absorbent body 4, and FIG. 36 is an enlarged cross-sectional view of the sheet-shaped absorbent body 4. As shown in FIG. 36, a sheet-like absorbent body 4 in which a PET tube 22 is provided on one side of a non-woven fabric 2 and SAP 23 is arranged thereon is shown in FIGS. 35 (a) to (b). As shown in Fig. 1, if the inner side of the bag is placed in the bag 11 so that the SAP is on the inside and the inner surface is the absorbing surface, the upper edge of the bag is folded inward to form the heel part 16; A pocket-like space is formed under the bag 6 between the bag body 11 and the bottom. Therefore, the urine discharged into the bag body 11 is absorbed near the bottom or the side of the bag body 11, and the urine in the bag body 11 is changed from the upper opening 10 by changing the body position. Even when trying to flow backward, urine flows into the pocket-like space and is absorbed by the lower surface of the buttocks 16, so it does not leak out.

 3. Third embodiment (Figs. 37 to 46): Curve seal & cut system

(1) Manufacturing method As shown in FIG. 37, while continuously feeding and conveying the nonwoven fabric 2 in a predetermined direction, a liquid impermeable sheet 3 having a width smaller than that of the nonwoven fabric 2 is supplied to the center of the nonwoven fabric 1 in a predetermined position. Then, they are stacked and joined continuously to form a band-shaped leak preventer that continues in a predetermined direction.

 As shown in FIG. 38, a plurality of absorbent bodies 4 having a width smaller than that of the liquid impermeable sheet 3 are arranged at appropriate intervals in a predetermined direction on the central portion in the width direction of the liquid impermeable sheet 3. Place them after a while.

 As shown in Figure 39, the two non-woven fabrics 2 and the liquid impervious sheet 3 are overlapped in the width direction, that is, in the predetermined direction in which the nonwoven fabric 2 and the liquid impervious sheet 3 are adjacent in the width direction. A plurality of elastic members 5 are respectively arranged in two continuous regions in a state where they are stretched in a predetermined direction. Leg holes 6 are formed at the boundary between the nonwoven fabric 2 and the liquid-impermeable sheet 3 in a subsequent process, so that there is room for forming the leg holes 6 without cutting the elastic members 5 and elastic on both sides of the leg holes 6. As in the first embodiment, a portion having a relatively wide interval a is provided in the interval of the elastic member 5 so that the member 5 is arranged. As shown in FIG. 40, both side edges in the width direction of the non-woven fabric 2 are folded inward, and the elastic member 5 of the elastic member 5 is sandwiched and bonded.

As shown in Fig. 4, the inner part of the nonwoven fabric 1 that is inside or folded back from the two boundary parts, and the part that is inside the both side edges of the nonwoven fabric 1 alternately pass between the absorbent bodies 4 arranged in a predetermined direction from the left and right. Cut with an S-shaped cutting line (indicated by a broken line in the figure). By this process, the member or material constituting the absorbent product 1b is divided into a right part on the right side and a left part on the left side in a predetermined direction. As shown in Fig. 42, turn one side of the cut right part and left part upside down and place it on the other side so that the cut-off line matches. In the example shown in the figure, the left part is superimposed on the right part so that the phases match. Then, it continuously seals along a continuous S-shaped cutline.

 As shown in FIG. 43, a leg hole 6 is formed through the predetermined direction at a position between the absorber 4 and the boundary region and without the elastic member 5. At the rain end of Leghole 6, there will be a skip cutter 21.

 As shown by the chain line in Fig. 44 (a), by sealing between the absorber 4 and the absorber 4 along the direction orthogonal to the predetermined direction, the absorber as shown in Fig. 44 (b) Separated into product 1c. The shape of the absorbent product 1c shown in Fig. 44 (b) is the individual shape at the moment when the sealing force is applied in the state where it is stretched with tension applied in a predetermined direction as shown in Fig. 44 (a). As shown in Fig. 45 (a), the upper body part 7 is contracted due to the contraction of the elastic member 5 at the moment when it is actually cut into seals and separated into individual products.

 4. Fourth embodiment (Figs. 47 to 65): Combined body and bag system

 (1) Manufacturing method

 As shown in FIG. 47, a plurality of elastic members 5 stretched in a predetermined direction are arranged in two portions on a strip-shaped nonwoven fabric 2 continuous in a predetermined direction.

 As shown in FIG. 48, both side edges in the width direction of the non-woven fabric 2 are folded back and bonded on the elastic member 5 of each portion.

As shown in Fig. 4-9, the non-woven fabric 2 is cut along the predetermined direction between the two parts and divided into two parts to form two band-like members that continue in two predetermined directions (the parts that will become the body part 7 when completed) As shown in Fig. 50, the side edges of the absorbent body 4 in the width direction are folded inward to form the flange 16. To do.

 As shown in FIG. 51, the absorbent body 4 is formed by cutting in a direction perpendicular to the predetermined direction along a cutting line indicated by a chain line, and appropriately setting the dimension in the predetermined direction.

 As shown in Fig. 52, a liquid-impervious sheet 3 that is continuous in a predetermined direction and has a width smaller than that of the non-woven fabric 2 is stacked at the center in the width direction of the belt-shaped nonwoven fabric 2 that is continuous in a predetermined direction. A plurality of absorbent bodies 4 having a width smaller than that of the liquid impermeable sheet 3 are arranged at appropriate intervals in a predetermined direction at the center in the width direction of the temporary sheet 3 and these are bonded and integrated. As shown in FIG. 53, a plurality of elastic members 5 extended in a predetermined direction are arranged on both side edges in the width direction of the liquid-impermeable sheet 3.

 As shown in FIG. 54, both side edges in the width direction of the non-woven fabric 2 are folded back inward and bonded with the elastic member 5 interposed therebetween, so that when completed, the bag portion 8 has an elastic band 20 for preventing liquid backflow. The part which becomes becomes.

 As described above, the portion to be the body portion 7 manufactured in the separate process and the portion to be the bag portion 8 manufactured in the separate step as described above are combined. First, as shown in FIG. 55, the portions to be the two body portions 7 are arranged along the predetermined direction at intervals in the width direction, and the portions to be the two body portions 7 (7), (7) In between, the part (8) which becomes the bag part 8 with the elastic band 20 along the predetermined direction is placed in a stretched state.

 Fig. 5 5 is a plan view of the overlapped state from above, Fig. 5 6 (a) is a plan view showing the hidden portion in Fig. 5 5 in order to clearly show the seal portion, and Fig. 5 6 (b) Shows the end view of Figure 55.

As shown in Fig. 5 7, the overlapping part of the part (7) that becomes the body part 7 and the part (8) that becomes the bag part 8 with the elastic band 20, and the part close to the absorber 4 are unjoined. Leghole 6 is constructed As a result, a crank-shaped seal portion 25 is formed at intervals in a predetermined direction. The shape of the seal portion 25 will be described in detail. The first seal portion along a predetermined direction from both side edges of one end portion of the absorber 4 in a predetermined direction to a region between the adjacent absorbers 4. 2 5 a and a second seal portion 25 b extending from the first seal portion 25 a to the portion (2 0) that becomes the stretchable band 20 along the width direction orthogonal to the first seal portion 25 a, The third seal portion along a predetermined direction that continues to the second seal portion 2 5 b and continues to the position corresponding to the middle portion of the absorbent body 4 adjacent along the portion (2 0) that becomes the stretchable band 20. Each of the seal portions 25 a, 25 b, and 25 c has a shape like a combination of two L-shapes that are substantially the same shape as a rotation target. .

 Then, along the center line passing through the center of the absorbent body 4 in the width direction and parallel to the predetermined direction, the absorbent body 4 is folded in half so that both side edges of the body portion 7 in the width direction overlap. .

 As indicated by the chain line in FIG. 58 (a), by passing through the second seal portion 25b between the absorber 4 and the absorber 4 along the direction orthogonal to the predetermined direction, the sealing force is increased. It is separated into absorbent product 1d as shown in Fig. 58 (b). The shape of the absorbent product 1d shown in Fig. 58 (b) is the individual shape at the moment when the seal is cut while being stretched with tension applied in a predetermined direction as shown in Fig. 58 (a). As shown in Fig. 5 9 (a), the upper body part 7 contracts due to the contraction of the elastic member 5 at the moment when the seals are cut and separated into individual products. The upper part of the lower bag part 8 is contracted and the lower part protrudes relatively back and forth.

According to the manufacturing method of the absorbent product 1d of this example, the elastic member 5 is sandwiched between non-woven fabrics, a portion that becomes a body portion 7 that is long in a predetermined direction, the non-woven fabric 2, the liquid-impermeable sheet 3, and the absorbent body 4 Become The portions that become the bag portions 8 that are long in the predetermined direction and have the elastic band 20 for preventing the liquid back flow are prepared in advance. Then, the bag portion 8 is placed on the two body portions 7 which are spaced apart from each other, and the bag portion 8 is placed on top of each other. The overlapping portion is sealed in a substantially crank shape to form the leg hole 6. Then, the whole is folded in half along a center line parallel to a predetermined direction, and a seal is cut through a seal portion between the absorber 4 and the absorber 4 along a direction perpendicular to the predetermined direction. Absorber product 1d separated. According to this example, the continuous and easy manufacturing method makes it easy to produce the absorbent product 1d in a form in which the bag portion 8 with the stretchable band is opened wider at the rear than the front of the wearer. In addition, there is an effect that mass production can be surely performed.

 (2) Structure (Fig. 59 to Fig. 65)

 Next, the structure of the absorbent product 1 d obtained by the above steps will be described with reference to FIGS. 59 (a) and (b) and FIGS. 60 to 65. These figures show the form of the absorbent product 1d of this example when it is spread out as if worn on the human body.

The absorbent product 1d of this example has the same basic structure as the absorbent product 1a of the first embodiment described with reference to FIGS. 7 (c) to (e). As shown in Fig. 60, Fig. 61, Fig. 63, and Fig. 64, the elastic band 20 provided so as to protrude inwardly on the upper edge of the bag portion is formed from both sides in front of the bag portion 8. It protrudes and has a narrow width. Moreover, since it is not bonded to the body part 7, it is not affected by the expansion and contraction of the body part. The upper opening 10 of the bag portion 8 containing the absorbent body 4 becomes narrower toward the front side of the wearer and becomes a closed state to form a urine socket. On the other hand, as shown in Fig. 59 (a) and Fig. 62 and Fig. 65, the stretchable band 20 behind the bag portion 8 is bonded to the body portion 7 on the outer side, so that it can be worn. The upper opening of the bag 8 is wide open on the back side of the wearer. Over space is secured.

 Therefore, according to the absorbent product 1d of this example, the urine discharged to the front (abdominal side) of the wearer is the front part of the bag part 8 in which the upper opening 10 is narrow and the elastic band 20 is provided. It is difficult to leak from the stool, and stool discharged to the back (back side) of the wearer is stored in the back part of the bag part 8 having a wide upper opening 10.

 In addition, the upper edge of the leg hole 6 has an elastic member 5 of the body part 7, and the lower edge has an elastic member 5 of an elastic band 20 of the bag part 8, and the circumferential surface of the wearer's leg and the leg hole 6 High adhesion is obtained between the periphery and liquid leakage and odor leakage are prevented.

 As described above, in any of the embodiments of the present invention, the bag portion 8 having the absorbent body 4 is disposed between both legs with the upper opening 10 facing the lower half of the wearer's legs. Since the urine discharged by the wearer is discharged into the bag 8, the possibility of urine adhering to the skin is low, and the skin is not likely to be irritated and the wearing feeling is also good. Moreover, since the urine moves inside the bag body 11, the internal absorbent body 4 can be used efficiently. In contrast, conventional absorbent products are placed with the absorbent body in close contact with the skin, and the body fluid (urine) that spreads between the skin and the absorbent body is absorbed only by the absorbent body that is in close contact therewith. However, the absorbent product 1d in this example is a revolutionary absorbent product 1d that adopts a completely different structure and absorption mechanism.

In any of the embodiments of the present invention, the continuous band-shaped material is transported in a predetermined direction while being overlapped or folded, and finally the seal is cut and separated into individual absorbent products to be completed. By the continuous and simple manufacturing method, it is possible to easily and surely mass-produce the absorbent product of this example having the above-described innovative absorption mechanism.
