Description

The present invention relates to a deployable absorbent article such as a pad type, a flat type, and a tape type, and a package thereof.

In addition to absorbent articles such as pad type and flat type (also called urine absorbing pad), tape type disposable diapers with both sides of the dorsal part detachable from the outer surface of the ventral part are in the product state. It is called a deployable type because it does not have a leg opening through which the legs pass through and is placed between the wearer's crotch from a flat or near-flat state. That is, the deployable absorbent article is different from the pants-type absorbent article having a leg opening in the product state.

In general, deployable absorbent articles are intended for people with paralysis or joint contracture (a condition in which the joints are stiff and difficult to bend and stretch), or for people who cannot lie on their backs and can only take a lateral decubitus position. There is a known problem that it is difficult to put on. Therefore, at the nursing care site, the caregiver folds the deployable absorbent article in half along the center line passing through the center in the width direction, and then inserts it between the wearer's crotch from one side to wear it. .. In this case, the caregiver needs to fold the deployable absorbent article in half, which complicates the mounting work.

As a solution to this problem, the one described in Patent Document 1 is one of the effective means. That is, in the case described in Patent Document 1, the deployable absorbent article is folded in half at the center line passing through the center in the width direction in the product state, and the facing surfaces are adhered to each other. The mold-absorbent article can be inserted directly between the wearer's crotch without folding it in half.

JP-A-2010-104658

However, when the deployable absorbent article described in Patent Document 1 is folded in half so that its surfaces face each other, the crotch portion of the article can be inserted between the wearer's crotch as it is. It does not fit properly to the crotch. More specifically, in proper wearing conditions, the crotch portion of the deployable absorbent article must be substantially arched (the shape from one inner thigh through the crotch to the other inner thigh). In the case of an absorbent article folded in half so that the surfaces face each other, if the absorbent article is simply inserted between the wearer's crotch, the crotch portion of the absorbent article will be in the opposite direction (upside-down arch shape). Therefore, in this case, the caregiver needs to repair the crotch portion.

Further, in the deployable absorbent article described in Patent Document 1, when the back surfaces thereof are folded in half so as to face each other, it is not necessary to rework the crotch portion, but the surface of the product is exposed to the outside, which is hygienic. Is not preferable. Further, in a deployable absorbent article having a buttock covering portion, if the back surfaces thereof are folded in half so as to face each other, the buttock covering portion warps in the opposite direction so as to be separated from the buttock portion, so this portion is reworked. There is also a need.

Therefore, a main object of the present invention is to provide a deployable absorbent article which is easier to wear and more preferable in terms of hygiene, and a package thereof.

The deployable absorbent articles that have solved the above problems are as follows.
<First aspect>
It has a crotch portion, a portion on the front side of the crotch portion, and a portion on the rear side of the crotch portion.
It has a front surface facing the wearer's skin and a back surface located on the opposite side.
It can be absorbed at least from the surface
At the first folding position along the width direction in the crotch portion, the ventral region located on the front side of the first folding position and the dorsal region located on the rear side of the first folding position are mutually aligned. Folded in half so that the surfaces of the
The ventral region is folded in half at a second folding position passing through the central portion in the width direction, and the back surface of the first portion located on one side of the second folding position in the ventral region and the ventral region. The back surface of the second portion located on the other side of the second folding position in the side region faces the back surface.
The dorsal region is folded in half at a third folding position passing through the central portion in the width direction, and the surface of the third portion located on one side of the third folding position in the dorsal region and the dorsal region. The ventral region is sandwiched between the surface of the fourth portion located on the other side of the third folding position in the side region.
A deployable absorbent article, characterized in that.

(Action effect)
When wearing the deployable absorbent article, first, the first part and the second part in the ventral region are picked with one hand, and the third part and the fourth part in the dorsal region are picked up with the other hand. While keeping the two folds at the second and third fold positions by picking, open the two folds at the first fold position to some extent (for example, about 90 degrees) by pulling the ventral region and the dorsal region apart. .. At this time, the ventral region has an arch shape in which the central portion in the width direction of the surface bulges toward the skin side, and the dorsal region has an inverted arch shape in which the central portion in the width direction dents. Next, while maintaining the bi-fold at the second folding position at least in the ventral region, the ventral region is inserted between the dorsal side and the crotch of the wearer and pulled out to the ventral side to align the wearing position. At this time, by pulling the dorsal region to the ventral region, the portion of the dorsal region near the ventral region is also deformed into an arch shape, and the entire crotch portion or substantially the entire crotch portion is arched, so that the wearer Get closer to a better fit for your crotch. Further, the portion of the dorsal region that is not affected by the shape of the ventral region is maintained in an inverted arch shape, that is, a shape along the surface of the buttocks. Therefore, the present deployable absorbent article requires little or no modification of the shape of the article when it is attached.
Further, the dorsal region is folded in half at a third folding position passing through the central portion in the width direction, and the surface of the third portion located on one side of the third folding position in the dorsal region and the dorsal region. Since the ventral region is sandwiched between the surface of the fourth portion located on the other side of the third folding position in the above, neither the surface of the ventral region nor the surface of the dorsal region is exposed at all. Or, the exposed area is small, which is hygienic.

<Second aspect>
The deployable absorbent article of the first aspect, which has a fixed portion to which the back surface of the first portion and the back surface of the second portion are joined to a central portion in the width direction at the rear end portion of the ventral region.

(Action effect)
If such a fixing portion is provided, the rear end portion of the ventral region is fixed in an arch shape not only during the wearing work by the caregiver but also during use. Is more likely to be arched, that is, to maintain a better fit to the wearer's crotch.

<Third aspect>
Built-in absorber over the fixed part and its surroundings
The absorber has a rigidity changing portion having a lower or higher rigidity than a portion located at the fixing portion at a portion adjacent to the rear of the fixing portion.
The deployable absorbent article of the second aspect.

(Action effect)
When the deployable absorbent article of the second aspect is attached, the central portion in the width direction of the surface of the fixed portion has an arch shape that bulges toward the skin, whereas the central portion in the width direction behind the fixed portion has an arch shape. Since the portion is recessed and has an inverted arch shape, the absorber tends to be twisted at the portion where the shape is switched from the former to the latter. When such a twist occurs, the wearer may feel a sense of discomfort in the crotch portion, and the absorption performance may be deteriorated. On the other hand, it is preferable to provide the rigidity changing portion at a position where the absorber is likely to be twisted as in the present embodiment because the absorber is less likely to be twisted.

<Fourth aspect>
It has a temporary fixing portion in which the first portion and the second portion are detachably joined.
A deployable absorbent article according to any one of the first to third aspects.

(Action effect)
Having such a temporary fixing portion makes it easy to insert the ventral region between the crotch of the wearer because the first portion and the second portion do not shift. Then, by peeling off the temporary fixing portion, the first portion and the second portion can be opened and the lower abdomen of the wearer can be covered with the ventral region. In addition, after inserting the ventral region between the wearer's crotch, the crease at the first folding position serves as a guide for the median line by not peeling off the temporary fixing part until the mounting position is aligned. Positioning becomes easy.
Further, since this adhesive portion can be peeled off, urine leakage from the ventral side can be prevented by adhering each of the peeled adhesive portions to the skin contact surface of the diaper located on the outside of the pad after the pad is attached.

<Fifth aspect>
The dorsal region has a notch in which both corners of the rear end are cut out, and both corners of the front end of the ventral region are exposed from the notch.
A deployable absorbent article according to any one of the first to fourth aspects.

(Action effect)
With such a notch, both corners of the exposed front end of the ventral region can be picked by hand, and by picking the front end of the ventral region, the third and fourth parts of the dorsal region can be picked up. The ventral and dorsal regions of the deployable absorbent article with the ventral region sandwiched between them can be easily pulled apart and opened while maintaining the bi-fold at the first, second and third fold positions. , Easy to make the state when attached.
The notch may be a straight line, a curved line such as an arc, or a combination thereof.

<Sixth aspect>
A packaging bag having a hexahedral storage portion and a large number of deployable absorbent articles of any one of the first to fifth, which are arranged and stored in the storage portion in the thickness direction, are included.
At least one surface of the packaging bag is an outlet surface on which an outlet for taking out the deployable absorbent article is formed.
The deployable absorbent article is aligned with the take-out surface so that both corners of the front end of the ventral region and both corners of the rear end of the dorsal region face each other.
A packaging for deployable absorbent articles.

(Action effect)
Each of the first to fifth aspects has a hygienic and compact shape in which the ventral region is sandwiched between the third portion and the fourth portion of the dorsal region. Can accommodate absorbent articles. When the deployable absorbent article is taken out from the packaging bag, since both corners of the ventral region and the dorsal region are aligned on the taking-out surface of the packaging bag, it is easy to pick up both corners with one hand and take them out.

According to the present invention, it is easier to wear and more preferable in terms of hygiene.

Hereinafter, an example of the deployable absorbent article will be described in detail with reference to the attached drawings.

1 to 9 show a deployable absorbent article. Although these figures show pad-type and flat-type deployable absorbent articles, the same aspect can be taken for tape-type disposable diapers. The present invention is not limited to the following embodiments.

(Structural example of deployable absorbent article)
As shown in FIG. 1 (c), the deployable absorbent article has a structure in which an absorber 6 is interposed between the top sheet 4 and the back sheet 5, and the excrement liquid that has permeated through the top sheet 4. Is absorbed and held by the absorber 6. The planar shape of the deployable absorbent article is not particularly limited, but it is generally substantially rectangular as shown in FIGS. 1 to 9.

As the top sheet 4 that covers the front side (skin contact surface side) of the absorber 6, a perforated or non-perforated non-woven fabric, a porous plastic sheet, or the like is preferably used. The material fibers constituting the non-woven fabric can be olefin-based fibers such as polyethylene or polypropylene, synthetic fibers such as polyester-based and polyamide-based, recycled fibers such as rayon and cupra, and natural fibers such as cotton. , A non-woven fabric obtained by an appropriate processing method such as a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in that it is rich in flexibility and drapeability, and the thermal bond method is excellent in that it is bulky and soft. When a large number of through holes are formed in the top sheet 4, urine or the like is rapidly absorbed.

The back sheet 5 that covers the back side (non-skin contact surface side) of the absorber 6 may be liquid permeable or liquid impermeable like the top sheet 4. In the case of liquid impermeability, a liquid impermeable plastic sheet such as polyethylene or polypropylene is used, but in recent years, one having moisture permeability is preferably used from the viewpoint of preventing stuffiness. The water-impervious / moisture-permeable sheet can be obtained by melting and kneading inorganic fine particles such as calcium carbonate in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching the sheet in a uniaxial or biaxial direction. A microporous sheet can be preferably used.

The absorber 6 may have a single-layer structure as shown in FIG. 1 (c), or may have a structure composed of a plurality of layers.
The absorber 6 is based on a known material, for example, a stack of pulp fibers, an aggregate of filaments such as cellulose acetate, or a non-woven fabric, and if necessary, a highly absorbent polymer is mixed and fixed. Can be used.
The absorber 6 can be packaged with a liquid-permeable and liquid-retaining packaging sheet such as crepe paper, if necessary, in order to retain the shape and polymer.
The absorber 6 is formed in a rectangular shape in FIGS. 1, 4, 5, 6, 7 and 9, but has an appropriate shape such as an hourglass shape having a constricted portion narrower than both front and rear sides in the crotch portion C. can do.

As shown in FIGS. 1 to 9, three-dimensional gather BSs that mainly fit around the legs may be formed on both sides of the top sheet 4. As shown in FIG. 1 (c), the three-dimensional gather BS has side edges fixed to both sides of the top sheet 4 of the deployable absorbent article, and the widthwise WD of the top sheet 4 from the side edges. It extends inward and is formed from a non-fixed, free-moving free part. An elongated gather elastic member 7 is arranged between the side edge portion and the back sheet 5. An elongated gather elastic member 7 is also arranged at the tip of the free portion. In the three-dimensional gather BS, the free portion protruding from the side edge portion of the top sheet 4 rises in the product state due to the contraction of the gather elastic member 7. As the three-dimensional gather BS, a non-woven fabric having water repellency is preferably used.

As the gather elastic member 7, commonly used materials such as styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicone, and polyester can be used. Further, in order to make it difficult to see from the outside, it is preferable to arrange the thickness at 925 dtex or less, the tension at 150 to 350%, and the interval at 7.0 mm or less. As the gather elastic member 7, a tape-shaped member having a certain width may be used in addition to the thread-shaped member as shown in the illustrated figure.

Similar to the top sheet 4, the material fibers constituting the above-mentioned three-dimensional gather BS are olefin-based fibers such as polyethylene and polypropylene, synthetic fibers such as polyester-based and polyamide-based, recycled fibers such as rayon and cupra, and natural fibers such as cotton. It can be a fiber, and a non-woven fabric obtained by an appropriate processing method such as a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. It is better to use a non-woven fabric that suppresses and has excellent breathability. Furthermore, for gathered sheets, silicone-based, paraffin metal-based, alkylchromic chloride-based water repellents, etc. are used to prevent the permeation of urine, etc., prevent fogging, and enhance the feel (dryness) to the skin. It is desirable to use a coated water repellent treated non-woven fabric.

(Example of deployable absorbent article)
As shown in FIG. 1A, when the deployable absorbent article is viewed from the top sheet 4 side, the QQ line of the width direction WD in the crotch portion C of the deployable absorbent article and the center of the width direction WD. Divided into four by the RR line of the front-back direction LD, the part corresponding to the left abdomen when worn is the first part M, the part corresponding to the right abdomen is the second part N, the part corresponding to the left back is the third part O, and the part corresponding to the right back is Let it be the fourth part P. Let the first part M and the second part N be the ventral region F, and the third part O and the fourth part P be the dorsal region B. The first part M, the second part N, the third part O, and the fourth part P refer to similarly corresponding parts in the first to sixth aspects of the present invention, and FIGS. In the plan view of the deployable absorbent article of Nos. 7 and 9, the positions similar to those shown in FIGS. 1 (a) and 1 (b) are shown.
When the total length of the product of the deployable absorbent article is Y, the crotch portion C is 0.2 to 0.3 Y from the center to the LD in the front-rear direction. 0.35 to 0.4Y from the crotch part C to the front end of the ventral region F of the deployable absorbent article is the lower abdomen L, and 0.35 to 0.4Y from the crotch part C to the rear end of the dorsal region B is the buttocks. Let it be H. This value varies depending on individual differences such as height, physique, and gender.
The first aspect 100 shown in FIGS. 1 to 3 is a deployable absorbent article 100 that maintains two folds at the first fold position 1, the second fold position 2, and the third fold position 3. The form without the three-dimensional gather BS in the figure is also included in the first aspect 100. In addition, all other aspects in the present specification also include a form having no three-dimensional gather BS.
As shown in FIGS. 2 and 3, the deployable absorbent article is pre-folded in two at the first, second and third folding positions 1, 2 and 3, so that the caregiver folds it in advance. No hassle, and you can prepare for installation in a short time. Further, the deployable absorbent article before mounting has a form as shown in FIG. 2, and the top sheet 4 is not exposed, so that it is hygienic.
As shown in FIGS. 1A and 1B, a first fold is formed between the first portion M and the second portion N in the ventral region F and the third portion O and the fourth portion P in the dorsal region B. The presence of position 1 makes it easier to align the first folding position 1 with the position of the wearer's crotch, and the presence of second and third folding positions 2 and 3 makes it easier to align the first folding position 1 with the position of the wearer's crotch. It is easy to align the center of 100. Therefore, the wearing time is shortened. As described in the action and effect of the first aspect 100, the first folding position 1 is by pulling the second folding position 2 to the ventral side at the time of mounting, and the second folding position 2 is pre-folded. As a result, the crotch portion C of the deployable absorbent article has a substantially arch shape, so that it is along the crotch of the wearer, and the third folding position 3 has an inverted arch shape, so that the buttock H is along the buttock of the wearer. .. For this reason, the wearer can reduce the discomfort when wearing the deployable absorbent article. In addition, since the wearer is in a state of being worn along the body of the wearer, leakage is less likely to occur.

In the second aspect 200 shown in FIG. 4, when folded, the backsheet 5 of the ventral region F is fixed by the first portion M and the second portion N. The fixing method is not particularly limited, and examples thereof include a method using a mechanical fastener, an adhesive, a heat seal, a hot melt adhesive, and the like. In the case of fixing with a mechanical fastener, as shown in FIG. 4B, a hook material 9 may be used for the first portion M and a tape material 8 may be used for the second portion N, or vice versa. When the back sheet 5 is a liquid-permeable non-woven fabric, as shown in FIG. 4D, the hook material 9 is adhered to at least one of the first portion M and the second portion N, and is directly adhered to the non-woven fabric. May be good.
By providing the fixing portion 10, the arch shape in the skin direction on the front side of the crotch portion C is strongly maintained as compared with the first aspect 100, so that the deployable absorbent article can be more easily adhered to the crotch of the wearer and is attached. Even when a person moves, the arch shape is maintained and leakage can be prevented.
Since the fixing portion 10 has the purpose of maintaining an arch shape along the crotch of the wearer, the apex portion of the arch shape in the anteroposterior LD in the widthwise WD center portion of the crotch portion C in the ventral region F of the deployable absorbent article. It should be in a place where you can maintain. The fixing portion 10 is located at least in the crotch portion C of the ventral region F of the deployable absorbent article, and assuming that the total length of the WD in the width direction is Z, the first portion from the center of the crotch portion C in the ventral region F in the width direction WD. It is preferably located inside the WD in the width direction from 0.25Z to M and 0.25Z to the second portion N, and more preferably located in the center of the WD in the crotch portion C width direction of the ventral region F. The shape of the fixing portion 10 is not fixed, and it is sufficient that the first portion M and the second portion N can be fixed.

In the second aspect 200, by providing the fixing portion 10 in the crotch portion C, the deployable absorbent article can be brought into close contact with the crotch of the wearer, but this causes an unnatural twist at the rear end of the fixing portion 10. May cause discomfort to the wearer and may cause leakage of urine discharged from the twisted part.
Therefore, in the third aspect 300, as shown in FIGS. 5 (b) and 6 (b), in the dorsal region B in contact with the rear end of the fixed portion 10, the absorber 6 on the extension line of the fixed portion 10 The rigidity changing portion 13 is provided to eliminate the twist generated at the rear end portion of the fixing portion 10, smooth the folding at the first folding position 1, and eliminate the discomfort in the crotch portion C of the wearer.
The rigidity changing portion 13 can be provided by providing the slit 11 of FIG. 5 and the embossing 12 of FIG. 6 in the absorber 6, or by partially increasing or decreasing the basis weight. Since such a rigidity changing portion 13 has a property of diffusing urine along its shape, if it is made vertically striped or vertically elongated, the diffusion of urine to the rear is promoted. Since the slit 11 in FIG. 5 is a low-rigidity portion, the depth of the groove portion is maintained even after urination, and urine is similarly diffused to the absorber even if there are a plurality of urinations. A plurality of embossed 12s in FIG. 6 extend from the rear end of the fixed portion 10 in the dorsal direction on the extension line of the fixed portion 10, and because of the high rigidity portion, even if the absorber 6 is twisted due to the movement of the wearer, The embossed shape is easy to maintain. When the amount of urine is large, the absorber in the embossed portion expands and the diffusion effect becomes low. Therefore, it is preferable to use a slit for a person with a large amount of urine and a deployable absorbent article having an embossed rigidity changing portion for a person with a small amount of urine.
The arrangement and dimensions of the rigidity changing portion 13 can be appropriately determined. When the width of the rigidity changing portion 13 is larger than half the width of the fixed portion 10, it is more preferable because it is easy to bend at the first folding position 1 and it is easy to eliminate the twist. Since the length of the anteroposterior LD of the rigidity changing portion 13 is within the length up to the crotch portion C in the dorsal region B of the deployable absorbent article, urine is not transmitted to the buttocks of the wearer. preferable. In addition, it is preferable that there is a length up to the crotch portion C so that even if a deviation occurs in the front-rear direction during mounting, it can be dealt with.

In the first to third aspects 100, 200, and 300, the deployable absorbent article is in close contact with the wearer's body, but the absorbent article located outside the deployable absorbent article, such as a tape-type diaper, is used. In relation to, it is not particularly followed.
In the fourth aspect 400 shown in FIGS. 7 and 8, in addition to the third aspect 300, the detachable temporary fixing portion 14 is attached to the back sheet 5 of at least one of the first portion M and the second portion N. By providing, the caregiver can easily pass the deployable absorbent article between the wearer's crotch and pull it out by hand picking it from the ventral side in order to maintain the double fold of the ventral region F at the second folding position 2. Cheap. Further, when the temporary fixing portion 14 is formed by the adhesive or the hook material 9 of the mechanical fastener provided on at least one of the back surface of the first portion M and the back surface of the second portion N, the temporary fixing portion 14 is peeled off and then attached to the outer. It can be used as a slip stopper. As shown in FIGS. 7B, 7D and 8A, the temporary fixing portion 14 may be made of a combination of the tape material 8 and the hook material 9 of the mechanical fastener. Assuming that one of the temporary fixing portions 14 is the tape material 8 and the other is the hook material 9, only the hook material 9 is attached to the outer when the temporary fixing portion 14 is attached to the outer, and the first portion M or the second portion N of the ventral region F is attached. One is fixed and the other may float, but as shown in FIGS. 7 (b), (d) and 8, both the first portion M and the second portion N have the tape material 8 and the hook material 9. Therefore, the first part M and the second part N can be temporarily fixed before mounting, and after mounting, both the first part M and the second part N can be temporarily fixed to the outer, and can be stably mounted. .. There is no limit to how the tape material 8 and the hook material 9 can be combined or used.
The temporary fixing portion 14 may be located at the first portion M and the second portion N, respectively, as long as the first portion M and the second portion N of the deployable absorbent article are adhered to the outer. Before the deployable absorbent article is attached, the first portion M and the second portion N are detachably bonded to each other, so that the first portion M and the second portion N are preferably provided at positions that are line-symmetrical with respect to the second folding position 2. However, if the temporary fixing portion 14 is located near the fixing portion 10, the arch shape may be forcibly opened and the effect of the fixing portion 10 may be reduced. Therefore, the temporary fixing portion 14 is preferably located at a position away from the fixing portion 10 in the ventral region F. Specifically, it is preferably located in the lower abdomen L of the first portion M and the second portion N of the deployable absorbent article, and as shown in FIGS. 7 (b) and 7 (d), the ventral region F When it is located at both corners of the above, it is the farthest from the fixed portion 10, and when the temporary fixing portion 14 is peeled off and adhered to the outer, the range in which the top sheet 4 on the absorber 6 is directly touched by hand is narrow, so that it is hygienic. Is also more preferable.
7 (a) and 7 (b) have a slit 11 in the dorsal region B. Specifically, it is an inverted triangular slit that extends from the rear end of the fixed portion 10 in the dorsal direction on the extension line of the fixed portion 10, and by making it triangular, the momentum of urine in the longitudinal direction is maintained rather than the strip shape. And diffusion is promoted. Further, when the rigidity changing portion 13 is formed in a horizontal stripe shape or a horizontally long shape, diffusion in the lateral direction is promoted, and when the rigidity changing portion 13 is formed in a shape in which the width expands toward the rear, it also has a diffusion promoting effect in the rear and lateral directions. preferable. 7 (c) and 7 (d) are preferable because they have embossing 12 and are rigidity changing portions 13 extending not only in the anteroposterior direction LD but also in the width direction WD, and urine is diffused in the posterior and lateral directions. The shape. Specifically, the embossed 12 in FIGS. 7 (c) and 7 (d) is in an arc state, so that the flow direction of urine is changed from one direction in the longitudinal direction to a lateral flow, and then the back. It can be diffused in the longitudinal direction along the embossed portion extending in the lateral direction. Since a plurality of embosses are formed in the longitudinal direction, it is possible to cope with a front-rear deviation. When the dorsal region B of the deployable absorbent article is long, the vertical striped or vertically elongated rigidity changing portion 13 which allows urine to flow backward, and when the length of the deployable absorbent article is short, the urine is flowed backward and laterally. The shape of the rigidity changing portion as shown in FIGS. 7 (b) and 7 (d) is preferable.

In the fifth aspect 500 shown in FIGS. 9A and 9B, in addition to the fourth aspect 400, both corners on the dorsal side are cut out. This is because when the deployable absorbent article is folded in two at the third folding position 3 and folded as shown in FIG. 9C, both corners of the ventral region F sandwiched between the dorsal regions B are exposed. Therefore, it is easy to pick up both exposed corners. When these two corners are pinched, the dorsal region B is smoothly separated from the folded form, and the ventral region F and the dorsal region B are opened by about 90 °, and when worn as shown in FIGS. 3 and 8 in a short time. Since it is in a state, it can be instantly prepared from the time when the deployable absorbent article is picked up to the time when it is attached, and the attachment time is further shortened.
If the absorber 6 is cut, the urine absorption capacity is affected. Therefore, the size of the notch 15 may be any size as long as it is up to the position where the absorber 6 is not present. In the case of a deployable absorbent article having a three-dimensional gathered BS, cutting the gathered elastic member 7 reduces the effect of the three-dimensional gathered BS, so it is preferable to cut the gathered elastic member 7 to a position where the gathered elastic member 7 is not present. From this, the length is between 0.1Y and 0.2Y from the rear end of the dorsal region B with respect to the total length Y of the deployable absorbent article, and the width is composed of the top sheet 4 and the back sheet 5. At the position, it is preferably notched.

(Folding form)
The folding form of the deployable absorbent article of the present invention is two at the first, second and third folding positions 1, 2 and 3, respectively, as shown in FIGS. 2 (b) and 9 (c). Maintains folding and takes a compact form.
Specifically, as shown in FIGS. 2A and 2B, in the crotch portion C in the anteroposterior direction LD, the first portion M and the second portion N of the ventral region F and the third portion O of the dorsal region B The first folding position 1 is opposed to the fourth portion P so that the top sheet 4 is opposed to each other, and the back sheet 5 of the first portion M of the ventral region F and the second portion N are opposed to each other. The front-back direction of the width direction WD center portion so that the second folding position 2 faces the front-rear direction LD of the width direction WD center portion and the top sheet 4 of the third portion O and the fourth portion P of the dorsal region B face each other. When a third folding position 3 is formed in the LD and the entire deployable absorbent article is viewed, the dorsal region B wraps the ventral region F. In the cross-sectional view in this folded form, as shown in FIGS. 2 (c), 5 (c) and 6 (c), the first portion M and the second portion N are the third portion O and the fourth portion P. It is sandwiched between.
As a manufacturing method, as shown in FIG. 2A, the first portion is a portion where the deployable absorbent article is folded in two at the crotch portion C so that the top sheet 4 faces the front-rear direction LD along the width direction WD. The folding position is 1, and the ventral region F and the dorsal region B are folded together, and the ventral region so that the back seats 5 of the first portion M and the second portion N face each other at the center of the width direction WD along the front-rear direction LD. The portion where F is folded in two is the second folding position 2, and the portion where the dorsal region B is folded in two is the third folding position 3. That is, as shown in FIG. 1A, the first folding position 1 is a valley fold along the QQ line when viewed from the top sheet 4 side, and the second folding position 2 is the ventral region F of the RR line. The third fold position 3 is a valley fold in the dorsal region B of the RR line.

The first folding position 1 can be appropriately determined, but usually, the position of 0.15Y on the front side (Y is the total length of the product) to the position of 0.15Y on the rear side with reference to the center of the LD in the front-rear direction of the product. Can be in the range up to. More preferably, the first folding position 1 is in a range from the position of 0.1Y on the front side to the position of 0.1Y on the rear side with respect to the center of the LD in the front-rear direction of the product. In order to make a compact product, it is preferable that the first folding position 1 is located at the center of the front-rear LD of the product, but the first folding position 1 is located behind the center of the front-rear LD of the product. Also, in the product state, the front end of the ventral region F protrudes from the rear end of the dorsal region B, which makes it easier to pinch the ventral region F, which is preferable.
Further, the crotch portion C is also set to the same range as the first folding position 1.
The second fold position 2 and the third fold position 3 extend in the front-rear direction LD at the center of the WD in the width direction and coincide with the center line of the wearer's body.

As shown in FIGS. 2 (a) and 9 (c), this aspect of the expandable absorbent article is compact because all of the first to fifth aspects are folded from the expanded state. Further, since the top sheet 4 is not exposed in the folded state, the portion that comes into contact with the skin is not directly touched by the hand before wearing, which is hygienic. And since the caregiver maintains the two folds at the first, second and third folding positions 1, 2 and 3 at the time of wearing, the caregiver does not need to fold the deployable absorbent article before wearing the wearer. be.

(Form when attached)
The mounted form of the deployable absorbent article of the present invention maintains two folds at the first, second and third fold positions 1, 2, and 3, respectively, as shown in FIGS. 3 and 8. ..
As described in the action and effect of the first aspect 100, the ventral region F and the dorsal region B are each picked with one hand, and while maintaining the double fold at the first fold position 1, the wearer's crotch is brought closer to the figure. As shown in 10 (a), while maintaining the double fold at the second fold position 2, the deployable absorbent article inserted into the crotch from the dorsal side is pulled out from the crotch, and at the third fold position 3. Place the created inverted arch along the wearer's buttocks. The presence of the first fold position 1 makes it easier for the deployable absorbent article to follow the crotch, and the presence of the second and third fold positions 2 and 3 makes the deployable absorbent article the centerline of the body. It can be easily matched. At the second folding position 2, the ventral region F is curved in an arch shape and runs along the crotch, so that a gap is less likely to occur between the deployable absorbent article and the wearer's body, and discomfort or leakage due to misalignment is less likely to occur. When the first portion M and the second portion N have the fixing portion 10, the arch-shaped bulge is strongly maintained, which is more effective. When the deployable absorbent article has a three-dimensional gather BS, the first folding position 1 is arched with respect to the wearer's crotch and the second folding position 2 is arched with respect to the wearer's lower abdomen. Since the three-dimensional gather BS rises and functions, it becomes easy to prevent leakage in the lateral direction.
When the deployable absorbent article is a pad type or a flat type and there is an absorbent article such as a tape type diaper on the outside, as shown in FIG. 10 (b), the first part M and the second part M of the ventral region F By peeling off the peelable temporary fixing portion 14 of the portion N and adhering the product to the outer absorbent article, it is easy to prevent leakage on the front side.

The packaging bag is a hexahedron, has an outlet 17 on at least one surface, and is aligned in the thickness direction so that both corners of the ventral region F and the dorsal region B of the expandable absorbent article folded into the outlet 17 are located. By packing the product, both corners of the deployable absorbent article can be picked and easily taken out. Since the dorsal region B and the ventral region F open smoothly, the unfoldable absorbent article taken out can be immediately prepared for wearing. As a packing method, the deployable absorbent article may be packed in only one stage as shown in FIG. 11A, or may be packed in a plurality of stages of two or more stages as shown in FIG. 11B. Further, in FIG. 11, the deployable absorbent article according to the fifth aspect 500 is packed, but the product to be packed is not limited, and the deployable absorbent article according to the first to fourth aspects may be packed. good.
