[Summary of the Invention]

On the other hand, there are low birth weight infants with a low body weight of less than 3,000 grams. In addition, there is a case where the low-weight child is born in the mother body and spends most of the time in a bending posture such as a child. This child's bending posture is also called a positioning posture. This posture is a state in which the C-shaped back is rounded as shown in Fig. 1A, and the leg portion is in an M-shaped opening as shown in Fig. 1B, and the knees are brought closer to the abdomen. In addition, it is placed in a prone posture by sleeping on a round seat (not shown), and the prone posture is performed, and most of the time is spent in a prone posture.

Moreover, from the viewpoint of not causing excessive stress on the low-weight child 101, there is a case where a method of minimizing treatment that does not touch the body is used. Further, for the low-weight child 101 as described above, a disposable disposable disposable diaper 1dp' can be used.

Here, in the prone posture, the target region 1at' of the first weir portion 1a' of the hook material 11m' as the locking portion of the fastening tape 11' is normally positioned on the ventral side of the low-weight child 101. That is, under the body of low birth weight infant 101. Therefore, when the paper urine portion is replaced, the body position of the low-weight child 101 is changed to the supine position, whereby the first arm portion 1a' is exposed upward, and the hook material 11m stuck in the target region 1at' is removed. 'The paper diaper 1dp' was unfolded, and the disposable diaper 1dp' was removed from the low birth weight infant 101.

However, the above-described positional change for removing the disposable diaper 1dp' is preferably performed as much as possible from the viewpoint of minimizing the treatment, and therefore, the unfolded type diaper which can be removed from the low-weight child 101 in a prone posture can be used. It is expected for medical institutions.

Figure 2A shows a disposable diaper that can be used in response to this expectation. 1dp illustration. As described above, in the prone posture, the second crotch portion 1b provided to protrude from the fastening tape 11 is positioned above the child 101, and the first cuff portion 1a having the target region 1at is positioned below the child 101. Here, in this reference example, the cut off line 1c for cutting the hook material 11m from the second weir portion 1b is provided. Therefore, by cutting the cut line 1c, as shown in FIG. 2B, the hook member 11m can be released from the target region 1at of the first arm portion 1a, and the first arm portion 1a and the second portion can be released. The connection of the crotch portion 1b can unfold the disposable diaper 1dp in a state of prone posture. Further, by this, the disposable diaper 1dp can be quickly removed from the low-weight child 101 in the prone posture.

However, the indoor illumination of the neonatal specific concentrated treatment room (NICU) in which the child 101 is normally accommodated is set to a low illuminance from the viewpoint of simulating the uterus environment of the mother. Therefore, the operator who is forced to change the disposable diaper performs the cutting operation in a dim environment, that is, the above-described cutting off line 1c is difficult to identify. Therefore, the operator may cut the position different from the cut off line 1c due to an error, and at this time, the paper diaper 1dp must be torn with a large force. As a result, the larger force acting on the child 101 imposes a great deal of pressure on the child, and as a result, the counter effect of the treatment is minimized.

Further, the child 101 is mostly raised in the incubator, but in this case, the above-mentioned paper and urine replacement is also performed in the same manner as the incubator. That is, two holes are provided in the side wall of the incubator, and the operator of the disposable diaper inserts the hand into the holes from the incubator to perform the replacement of the disposable diaper of the child 101. However, in this way, the operator must pass the incubator The transparent box is used to identify the cut line 1c, and as a result, the cut off line 1c is more difficult to identify.

The present invention has been made in view of the above-described problems, and an object thereof is to provide a disposable disposable diaper which is provided with a locking portion which is cut away from the fastening tape by the second weir portion. Offline, it can be removed from the target person in the prone position, and the position of the cut off line can be easily recognized.

The main invention for achieving the above object is an unfolded disposable diaper having a longitudinal direction, a transverse direction, and a thickness direction, and a diaper main body portion having a first rim portion and a lower portion arranged in the longitudinal direction. In the second weir portion, the locking portion of the fastening tape that is provided to protrude from the second weir portion toward the outer side in the lateral direction is locked to the first weir portion, thereby connecting the first weir portion A disposable disposable diaper having an opening type and a pair of foot opening portions is formed in the second weir portion, and at least the locking portion of the fastening tape is provided The second weir portion is cut off and cut off, and is provided with a mark corresponding to at least a portion of the cut off line and displaying the position of the portion.

Further features of the present invention will become apparent from the description of the specification and the appended claims.

According to the present invention, it is possible to provide a disposable disposable diaper which is provided with an unfolded disposable diaper which is provided for cutting off the locking portion of the fastening tape from the second weir portion, whereby the target person can be taken from the prone position In addition, the location of the cut off line can be easily identified.

Fig. 6 is an enlarged view of a main portion for explaining the cutting line 1c. This Fig. 6 shows that the cut line 1c is a portion 1bk in which the tape substrate 11a which can be cut and fixed with the fastening tape 11 is formed by stitching in the second weir portion 1b (in Fig. 6, indicated by oblique lines) The portion 1bk, hereinafter, is also referred to as a fastening tape fixing portion 1bk). Specifically, the cutting line 1c is formed on each of the second side flaps 1bsf corresponding to each of the fastening belts 11. In addition, each of the cut-off lines 1c is located in the second rim portion 1b, and is moved from the portion 1bHB which is the dam opening portion 1HB to the inner side of the fastening tape fixing portion 1bk. The weir portion 1b is formed as a path extending on the portion 1bHL side of the foot opening portion 1HL.

Thereby, the low-weight child 101 in the prone posture shown in Fig. 2A can be quickly removed from the disposable diaper 1dp as shown in Fig. 2B. That is, as shown in Fig. 2A, the second rim portion 1b side of the fastening tape 11 is usually fixed, and the diaper 1dp is attached to the low-weight child in such a manner as to be positioned on the back side of the low-weight child 101. 101. Therefore, in the prone posture, the second weir portion 1b is located above the vertical direction, but the fastening tape of the second weir portion 1b can be cut off by the above-described cut-off line 1c according to the disposable diaper 1dp. Fixed part 1bk (Fig. 2B). In addition, the hook material 11m of the fastening tape 11 can be separated from the second weir portion 1b, and as a result, the hook material 11m of the fastening tape 11 is maintained in the state of being locked to the first weir portion 1a. The connection between the first weir portion 1a and the second weir portion 1b can be released. The paper diaper 1dp unfolded. Thereby, the second rim 1b is finally pulled out toward the rear (foot side), and the disposable diaper 1dp can be removed from the low-weight child 101 in the prone position.

Further, the stitch trace of the cut line 1c is an aggregate of a plurality of linear slits. In other words, the linear slits (not shown) penetrating the second side flaps 1bsf in the thickness direction are arranged in plural in the direction in which the cutting line 1c is to extend. Further, the length of the slit or the pitch of the slit may be appropriately set in consideration of the cutting property or the like. However, in the case of a specific example, the length of the slit may be, for example, 1 mm to 3 mm, and the interval between the slit and the slit. (That is, the length of the gap-free portion between the slits), for example, 0.5 mm to 2 mm can be exemplified. Incidentally, the pitch of the above slits may also be referred to as the sum of the length of the slit and the above interval.

Further, in this example, as shown in Fig. 6, the cut line 1c formed in one of the second side flaps 1bsf and the cut line 1c formed in the other second side flap 1bsf are formed in the center line C1 of the disposable diaper 1dp in the lateral direction. Symmetrical to the line. Further, each of the cut lines 1c is formed in a substantially J shape having a curved portion 1cL along the longitudinal direction and a curved portion 1cB having a curved shape.

The linear portion 1cL is a portion 1bHB which becomes the opening portion 1HB among the second rim portions 1b, that is, the substantially outer edge 1be1 of the longitudinal direction of the second rim portion 1b, starting from the longitudinal direction The straight line advances toward the inner side in the longitudinal direction and reaches the same position as the position of the fastening tape 11 in the longitudinal direction or a position inside the inner side of the position. Further, the curved portion 1cB is joined at this position, whereby the curved portion 1cB further extends toward the inner side in the longitudinal direction. More specifically, the curved portion 1cB is As it advances toward the inner side in the longitudinal direction, it is displaced toward the lateral outer side by a predetermined radius of curvature, and finally reaches the portion 1bHL which becomes the foot opening portion 1HL among the second weir portion 1b, that is, the lateral direction of the second weir portion 1b. The outer edge 1be2.

Further, according to the path of the cut line 1c, the line 1c completely surrounds the fastening tape fixing portion 1bk from the inner side in the lateral direction. Therefore, when the cutting line 1c is cut, the hook material 11m of the fastening tape 11 can be cut away from the second weir portion 1b by including the entire fastening tape 11 of the fastening tape fixing portion 1bk.

Further, as long as the curved portion 1cB as described above is provided, the cutting line 1c can be reached by a path shorter than the outer edge 1be2 of the lateral direction of the second weir portion 1b. That is, it is not necessary to form a large extension of the path of the cut line 1c toward the inner side in the longitudinal direction. Further, the path of the cutting line 1c causes a problem in that a large extension is formed on the inner side in the longitudinal direction. For example, when the path reaches the first side flap 1asf (Fig. 3), the low weight of the positioning posture can be effectively prevented. It is difficult to cut the abdomen of the child 101 and the M-shaped foot to hold a part of the ablation line 1c.

Incidentally, in the example of Fig. 6, the cut line 1c is completely incorporated into the second side flap 1bsf, but is not limited thereto. That is, depending on the condition, a portion of the resection line 1c may also be exposed on the 1 msf side of the lower flank. However, when the amount of exposure is too large, it is easy to be caught between the abdomen of the low-weight child 101 and the M-shaped foot, or the cutting length is long, and the like, it is difficult to cut the above-described cutting line 1c.

Further, in this example, a plurality of sheets 4, 5, and 6 are present at the position where the linear portion 1cL is formed. Specifically, from the thickness direction The three sides of the three-dimensional pleats 6, the leakage preventing sheets 4, and the outer wrapping sheets 5 are present on the skin side, and the number of laminated sheets of the sheets is three. Therefore, the linear portion 1cL is formed with stitches through the three sheets 4, 5, and 6 which are laminated.

On the other hand, as already explained, the curved portion 1cB is formed to be displaced toward the lateral outer side as it enters the longitudinal inner side. Therefore, the number of laminated sheets of the sheet varies with the process from one end of the curved portion 1cB to the other end. That is, as shown in the left half of Fig. 6, in the portion 1cB1 of the predetermined range which is continuous with the linear portion 1cL among the curved portion 1cB, the number of laminated sheets of the sheet is the same as the above-mentioned linear portion 1cL Similarly, in the curved portion 1cB, the portion 1cB2 which is more adjacent to the inner side in the longitudinal direction than the portion 1cB1 of the predetermined range described above, since the leak preventing sheet 4 is not present, it becomes the three-dimensional pleat sheet 6 and the outer portion. Two pieces of the packaging sheet 5 are formed. Therefore, the former portion 1cB1 is formed with stitches through the three sheets 4, 5, and 6, but the latter portion 1cB2 is formed by the two sheets 5, 6 forming stitch stitches.

Further, even if a portion 1cB2 of the curved portion 1cB is reduced as described above, it is relatively easy to cut the portion 1cB2 when the number of laminated sheets of the sheet is small. Therefore, it is easy to cut the curve which is more difficult than the general straight line, and as a result, the curved portion 1cB can be correctly cut along the curved target shape.

Further, in this example, the improvement in the stitching is made such that the cutting ease of the cutting line 1c differs depending on the position in the longitudinal direction. For example, as shown in Fig. 7, when the cut line 1c is divided into three vertical portions 1c1, 1c2, and 1c3, the corresponding portions 1c1, 1c2 are corresponding. 1c3 sets the ease of cutting. More specifically, the first portion 1c1 which is the one portion 1c1 among the three portions 1c1, 1c2, and 1c3 is located in the second surrounding portion 1b and includes the portion 1bHB which becomes the opening portion 1HB. Position, but the first part 1c1 is a stitch that is easy to cut. Further, the second portion 1c2 which is the other portion 1c2 includes the same position as the fastening tape fixing portion 1bk in the longitudinal position, but the second portion 1c2 is formed to be difficult to cut than the first portion 1c1. Stitch stitches. Further, although the third portion 1c3 of the remaining portion 1c3 is the above-described curved portion 1cB, the third portion 1c3 is a slit which is easy to cut in the same specifications as the first portion 1c1.

Further, according to the above, when the respective diaper tapes 11 and 11 of the low-weight child 101 are attached to the outer side of the horizontal direction, the stitches are difficult to be cut according to the second portion 1c2. It can effectively prevent the cutting line 1c from being accidentally cut. In addition, when the diaper 1dp is removed from the low-weight babies 101, the stitches can be easily cut according to the first portion 1c1, and the cutting can be easily started from the portion 1bHB which becomes the dam opening 1HB. The curved portion 1cB of the portion 3c3 can also be correctly cut along the curved shape of the target portion 1cB according to the stitching which is easily cut.

Incidentally, the above-described easy-to-cut stitching and the setting of the stitches which are difficult to cut are realized by the change of the slit length which the stitching has, and the example is as described above. That is, this example is to maintain a certain gap between the gaps, and to make the length of the slit different, so that the ratio of the length of the slit per unit length in the direction in which the cut line 1c extends is in the above portion. 1c2 and the above-mentioned portions 1c1 and 1c3 are different from each other. Generally, when the ratio is large, it is easy to cut, and when the ratio is small, it is difficult to cut. Therefore, in this example, the ratio of the second portion 1c2 is set to be smaller than the ratio of the first portion 1c1 and the third portion 1c3.

Moreover, in the example of the third figure, the cutting lines 1ca are formed by the stitches in the first side flaps 1asf and 1asf of the first armrest portion 1a. In other words, the first side flap 1asf extends from the longitudinal outer edge 1asfe toward the inner side in the longitudinal direction to form the cutting line 1ca. Further, the lateral formation position of the cutting line 1ca coincides with the formation position of the cutting line 1c of the outer end edge 1bsfe of the longitudinal direction of the second side flap 1bsf.

Therefore, a relatively wide interval can be formed between the cutting lines 1ca and 1ca in the first weir portion 1a. Then, after the cutting stitches of the respective cutting lines 1ca and 1ca are cut, the portion 1am between the cutting lines 1ca and 1ca is folded back in the first narrowing portion 1a, so that the low-weight child 101 can be made. The abdomen is exposed, which is effective when it is necessary to perform appropriate treatment such as light treatment on the abdomen. Further, after the cutting lines 1ca and 1ca are cut, the respective cutting lines 1ca and 1ca can be easily opened in the lateral direction, so that the first weir portion 1a is soft and deformable in the lateral direction. Therefore, even a low-weight, high-born child 101 with a large abdomen can be smoothly loaded.

<<<Resection line with mark Q>>>

As shown in Fig. 6, in this example, as the cutting line mark Q, the notch portion k1 is formed corresponding to one end portion 1ce1 of the same line 1c which is the cutting position of the cutting line 1c. That is, outside the longitudinal direction of the second weir 1b The portion of the end edge 1be1 where the cut line 1c is positioned forms a substantially V-shaped portion of the notch portion k1 recessed toward the inner side in the longitudinal direction. Therefore, the operator who replaces the disposable diaper recognizes the start cutting position of the cut line 1c not only by visually touching the notch portion k1 by hand. Therefore, even in a dim work environment, the position of the cut line 1c can be more surely recognized.

Further, according to the notch effect of the notch portion k1, the cutting of the cutting line 1c can be relatively easily performed when the cutting of the cutting line 1c is started. Therefore, the cutting of the cutting line 1c can be smoothly and stably performed, and as a result, the cutting operation can be easily performed. .

Further, from the viewpoint of surely enjoying the effect of the notch, it is preferable to include the end portion 1ce1 of the cut line 1c in the notch portion k1 as shown in Fig. 6 . However, this is not a limitation. For example, as shown in Fig. 8, the end portion 1ce1 of the cut line 1c may be positioned at a position separated from the notch portion k1 by only 1 mm to 3 mm in the lateral direction. That is, the end portion 1ce1 of the cutting line 1c may be positioned outside the notch portion k1. Further, at this time, it is possible to effectively prevent the cut-off line 1c from being accidentally broken when the second side flap 1bsf is pulled outward in the lateral direction after the notch effect is weakened.

The dimension in the longitudinal direction of the recessed portion k1 in the recessed direction is, for example, set to a maximum value of 2 mm to 20 mm, and the dimension in the lateral direction orthogonal to the recessed direction is, for example, set to a maximum value of 2 mm to 15 mm. range. The shape of the notch portion k1 is not limited to the above-described substantially V-shape, and may be, for example, a U-shape or a shape other than the above.

And, depending on the situation, as shown in Figure 9, it can also correspond to the cut. The other end portion 1ce2 of the wire 1c is formed with a notch portion k2 instead of or in addition to the above-described notch portion k1. In other words, the portion where the line 1c is positioned may be cut out in the lateral outer edge 1be2 of the second weir portion 1b to form a notch portion k2 recessed toward the inner side in the lateral direction. Further, at this time, the same effect as described above can be achieved also for the other end portion 1ce2 of the cut line 1c.

Further, depending on the situation, as shown in FIG. 10, the scooping portions T1 and T2 may be formed instead of the notch portions k1 and k2 as the cutting line mark Q. That is, the portion of the longitudinal outer edge 1be1 of the second weir portion 1b that is positioned with respect to the resection line 1c is a projection T1 that protrudes outwardly in a substantially V-shaped longitudinal direction, and may also be as shown in FIG. The portion of the lateral outer edge 1be2 of the second weir portion 1b that is positioned with respect to the resection line 1c is a projection T2 that protrudes outward in a substantially V-shape toward the lateral direction. Further, by the above-described capturing portions T1 and T2, the operator who replaces the disposable diaper recognizes the starting cutting position of the cutting line 1c not only by visual inspection but also by the touch of the hand.

The dimension of the protruding direction of the relevant capturing portions T1 and T2 is, for example, a range in which the maximum value is set to 2 mm to 20 mm, and the dimension in the direction orthogonal to the protruding direction is, for example, a range in which the maximum value is set to 2 mm to 15 mm. Further, the shapes of the capturing portions T1 and T2 are not limited to the above-described substantially V-shape, and may be U-shaped or other shapes.

Further, as described above, the scooping portions T1 and T2 have a function as a scooping portion for scooping the cutting line 1c. However, in this case, the scooping portions T1 and T2 and the resection line are preferable. The positional relationship of 1c is formed as follows. In other words, when the capturing portion T1 is formed in the longitudinal outer edge 1be1 of the second weir portion 1b, one end of the cutting line 1c is cut. The portion 1ce1 may be positioned at the start protruding position PT1 at which the capturing portion T1 starts to protrude in the longitudinal direction. In addition, when the operator moves the same capturing portion T1 toward the inner side in the longitudinal direction with the capturing portion T1 as the scooping portion, the cutting line 1c can be quickly cut. Similarly, in the latter case, when the scooping portion T2 is formed in the lateral outer edge 1be2 of the second rim portion 1b, the other end portion 1ce2 of the resection line 1c is positioned at the scooping portion T2 to start to protrude laterally. Start to highlight position PT2. In addition, when the operator moves the scooping portion T2 toward the inner side in the lateral direction with the scooping portion T2 as the scooping portion, the cutting line 1c can be quickly cut.

However, the positional relationship between the start protruding position PT1 (PT2) of the capturing portion T1 (T2) and the end portion 1ce1 (1ce2) of the cutting line 1c is not limited to the above. That is, the start protruding position PT1 (PT2) of the capturing portion T1 (T2) may be separated by a predetermined separation distance from the end portion 1ce1 (1ce2) of the cutting line 1c. Further, as long as it is separated as described above, the effect similar to the notch effect achieved by the start of the protruding position PT1 (PT2) and the concave curved portion at the vicinity thereof can be made weak, and as a result, the cut line 1c can be effectively prevented from being accidentally caused. Cutting. Incidentally, the above-described separation distance is selected, for example, from a range of 1 mm to 20 mm.

11 to 15 are explanatory views of a modification of the cutting line mark Q. In addition, any of the figures is a schematic top view in which the disposable diaper main body 1 is displayed from the skin side in the thickness direction.

In the above-described embodiment, the cut line markings Q are, for example, the notch portions k1 and k2 or the scooping portions T1 and T2. However, in the modification of the eleventh to fifteenth drawings, the pattern is drawn in the disposable diaper main body portion 1. The standard Remember Q. That is, in any of the modifications, the pattern Z is drawn along at least a portion of the cutting line 1c in the second weir portion 1b. Further, as described above, the operator can easily visually recognize the position of the cut line 1c.

Incidentally, in the modification of Fig. 11, the plural arrows along the pattern Z of the cut line 1c are drawn in line. Further, in this example, although the arrow is superimposed on the cut line 1c, it may be drawn in a range of ±2 mm in the vertical direction and the horizontal direction depending on the situation. Further, a triangle (not shown) of a plurality of associative arrows may be drawn instead of the arrow, or as indicated by a dot pattern in Fig. 12, a strip pattern Z laterally crossing the cut line 1c may be drawn along the cut line 1c. Further, as in the modification of Fig. 13, a region laterally outward of the cut line 1c may be colored (see a dot pattern) as the pattern Z along the cut line 1c.

Further, as in the modification of Fig. 14, the straight line ZL along the linear portion 1cL of the cut line 1c may be drawn as a pattern Z by a dotted line or a solid line across the entire longitudinal direction of the diaper main body portion 1, or as in the fifteenth In the modification of the figure, a region laterally outward of the straight line ZL can be colored (see a dot pattern) as the pattern Z along the cut line 1c.

Further, the target surface on which the pattern Z is drawn is generally the non-skin side of the outer sheet 5, which is the case. However, it is not limited as long as it can be recognized from the non-skin side in the thickness direction. For example, in this example, the outer cover sheet 5 is a non-woven fabric. Therefore, even when the pattern Z is drawn on the skin side surface of the sheet 5, the sheet 5 can be made to recognize the pattern Z by light transmission. Also, in the case where the pattern Z is drawn on the non-skin side of the leakage preventing sheet 4, the outer sheet 5 can also be discriminated in a light-transmissive manner to prevent leakage. The pattern Z of the sheet 4. Therefore, the target surface on which the pattern Z is drawn may be the skin surface side of the exterior sheet 5 or the non-skin surface side of the leakage preventing sheet 4.

Further, a conventional printing method can be exemplified for the method of drawing the pattern Z. That is, inkjet printing, flexographic printing, screen printing, and the like can be exemplified.

However, in the above-described embodiment, the example of the cut off line is an example in which the substantially J-shaped cut line 1c is displayed on the plane, but the present invention is not limited thereto. For example, it may be a modification of Fig. 16 or Fig. 17.

That is, first, the cut line 1c' of the modification shown in Fig. 16 does not have the curved portion 1cB, and has only the straight portion 1cL. In detail, in this modification, the cut line 1c' is located outside the transverse line 1c, whereby the fastening tape fixing portion 1bk can be cut only by a straight portion 1cL along the longitudinal direction. Further, according to the above-described cutting line 1c', since only the linear portion 1cL is provided, the cutting is easy, and as a result, it is not necessary to form a large offset from the cutting line 1c', and the cutting can be accurately performed.

In this example, as the cutting line mark Q, the notch portions k1 and k1 are formed in the end portions 1ce1' and 1ce2' of the respective cut lines 1c. However, the above-described capturing portion T1 may be formed or drawn. The above-described pattern Z replaces the notch portion k1.

On the other hand, the cutting line 1c" of the modification of Fig. 17 is formed in a substantially U-shape that surrounds the fastening tape fixing portion 1bk from three sides. That is, with respect to the cutting line 1c", the starting end Ps is in the first 2, the lateral outermost edge 1bsfee of the second side flap 1bsf of the surrounding portion 1b, the fastening tape fixing portion 1bk thus extending into the inner peripheral side of the substantially U-shaped path, most Thereafter, the outermost edge 1bsfee of the lateral direction of the second side flap 1bsf is reached in the same manner as the above-described starting end Ps, and the position Pe reaching the outermost edge 1bsfee is used as the terminal Pe of the cut-off line 1c".

In this example, as the cutting line mark Q, the capturing portions T2 and T2 are formed in the end portions 1ce1" and 1ce2" of the respective cutting lines 1c", but the above-described notch portion k2 or the like may be formed. The pattern Z described above is substituted for the capturing portion T2.

However, at the outset, the disposable diaper 1dp of the present embodiment is particularly suitable for a low-weight child 101 of 3000 gram or less. However, the disposable diaper 1dp can effectively solve the above-mentioned problems associated with the positioning posture and the minimized treatment. Further, it is required to make the positioning posture easier, and the disposable diaper 1dp is more effective. Moreover, this occasion is a case where the weight is lighter.

Therefore, the disposable diaper 1dp of the present embodiment is preferably a low birth weight infant of 1500 gram or more and less than 2500 gram, and is preferably used for a very low birth weight infant of 1000 gram or more and less than 1500 gram. It is best for children born under 1000 grams of ultra-low weight.

Further, the disposable diaper 1dp of the present embodiment is specialized for the low-weight child 101, and is formed to be smaller than the existing disposable diaper 1dp. For example, the product length L1 of the disposable diaper 1dp for newborns is 365 mm, and the circumference L1HB of the opening portion 1HB of the attached state is 304 mm. In the disposable diaper 1dp of the present embodiment, the length L1 of the product is set. 3)) is 210~330mm, and the opening part of the state is installed. The circumference of 1HB is L1HB of 160 to 295 mm.

Further, the product length L1 is measured, for example, in a state in which the disposable diaper 1dp is unfolded. In other words, as shown in Fig. 3, in the unfolded state, the locking of the fastening tapes 11 and 11 of the target region 1at is first released, and the first weir portion 1a and the crotch portion 1m and the second weir portion 1b are formed. The diaper 1dp becomes a state in which the contraction of the three-dimensional pleats 6 by the three-dimensional hem elastic member 6r and the contraction of the lower side flaps 1msf and 1msf of the foot elastic members 21 and 21 are eliminated. A state of stretching toward the longitudinal direction. Further, the longitudinal maximum dimension L1 of the stretched state is measured so that the measured value becomes the above-described article length L1.

On the other hand, with respect to the circumferential length L1HB of the above-described surrounding opening portion 1HB, the pair of fastening tapes 11 and 11 are measured in a locked state in which the fastening tapes are overlapped. Figure 18 is an explanatory diagram thereof. Further, in the following, for convenience of explanation, the fastening tape 11 of the second side flap 1bsf positioned on the left side in Fig. 18 is the "left side belt 11-1", and is also referred to as the fastening belt 11 of the second side flap 1bsf on the right side. It is "11-2 on the right side".

First, as preparation for measurement, the two fastening tapes 11-1 and 11-2 are formed in a locked state in which the fastening tapes are overlapped. That is, as shown in Fig. 18, after the hook material 11m of the left side belt 11-1 is locked to the target area 1at of the first weir portion 1a, the hook material 11m of the right side belt 11-2 is locked to the left side belt. 11-1's non-skin side 11-1s. However, at this time, the longitudinal center positions C11-1 and C11-2 of the belts 11-1 and 11-2 are aligned with each other, and the front end 11-2e and the left side belt of the right side belt 11-2 are aligned. The end 11me of the root side of the hook material 11m of 11-1 is identical. And by this Fasten the locked state of the overlapping form.

In this manner, the opening portion 1HB formed in the locked state is extended until the expansion and contraction of the elastic member 21 is completely eliminated. Then, in the relevant extended state, the circumferential length L1HB of the opening 1HB is measured, thereby obtaining the circumferential length L1HB.

Incidentally, an example of the product length L1 of the birth weight low birth weight and the circumference L1HB of the opening portion 1HB may be, for example, 310 mm and 273.5 mm, respectively, and the product length L1 and the opening of the circumference of the extremely low birth weight infant. An example of the circumference L1HB of 1HB may be, for example, 270 mm and 220 mm, and an example of the product length L1 of the birth of the ultra-low-weight child and the circumference L1HB of the circumference opening 1HB may be, for example, 230 mm and 219 mm, respectively.

The embodiments of the present invention have been described above, and the above-described embodiments are for facilitating the understanding of the present invention and are not intended to limit the use of the present invention. Further, the present invention can be modified and improved without departing from the spirit and scope of the invention, and the equivalents thereof are of course included in the present invention. For example, the deformations shown below can be made.

In the above-described embodiment, the hook material 11m is exemplified as the locking portion 11m of the fastening tape 11, but the present invention is not limited thereto as long as it can be locked to the target region 1at of the first collar portion 1a. For example, an adhesive tape can also be used as the locking portion 11m.

In the above embodiment, the shape shown in Fig. 6 is exemplified. The cut line 1c formed in the second weir portion 1b is taken as an example of cut off line. In other words, in the second weir portion 1b, the cut-off line 1c is used for cutting the fastening tape fixing portion 1bk as the portion 1bk to which the fastening tape 11 is fixed, but is not limited thereto. In other words, the disposable diaper 1dp can be removed from the low-weight child 101 in the prone posture as long as it is cut off from the hook portion 11m of the fastening tape 11 from the second weir portion 1b. The representation of the cut off line 11ac is also included in the scope of the present invention. That is, it is also within the scope of the present invention that the portion between the fastening tape fixing portion 1bk and the hook member 11m in the tape substrate 11a of the fastening tape 11 is formed with the cut off line 11ac in the longitudinal direction.

Incidentally, in the example of Fig. 19, the end portions 11ace1 and 11ace2 corresponding to the cut-off line 11ac are respectively formed with the notch portions k1 and k1 of the mark Q as the cut-off line 11ac in the tape base material 11a of the fastening tape 11 But not limited by this. In other words, the above-described capturing portion T1 or the above-described pattern Z may be formed instead of the notch portion k1.

In the above-described embodiment, the stitches are exemplified as the cut lines 1c, 1c', and 1c" and the cut off line 11ac. The stitches are an aggregate of a plurality of linear slits, but are not limited thereto. For example, it may be a circular arc or a wave-shaped slit along the extending direction of the cutting lines 1c, 1c', 1c" or the like, or a through hole having a circular or elliptical planar shape instead of the slit. .

In the above-described embodiment, the stitches are exemplified as the cut lines 1c, 1c', and 1c" and the cut off line 11ac. However, the stitch line 1c is not limited thereto, that is, the cut line 1c is easily cut as compared with the surrounding portion. 1c', 1c", etc. may be outside the stitching. For example, the cutting cut line 1c may be formed by pressing or pressing a plurality of concave portions formed by melting or continuous groove-like recesses in the thickness direction. 1c', 1c", etc.

The above-described embodiment is mainly directed to the disposable disposable diaper 1dp which is removed from the target person 101 in the prone posture. However, the present invention is not limited thereto, and of course, it may be removed from the target person 101 in the supine posture. .
