Description

  The present invention relates to a deployable diaper or diaper cover.

  Disposable diapers are broadly classified into pants and unfolded types. The former pants-type diaper is a type of diaper that has a continuous girth like a brief and is worn from the waist to the leg opening through the wearer's toe through the foot.

  In this pants-type diaper, a crotch part is divided and the divided abdomen and back are detachably connected (Patent Document 1). Specifically, there is a sheet-like flap having no absorbent core at the edge of the portion divided at the crotch portion, and a male material of the fastening tape is provided on one side (back side) of this flap portion. On the other hand, in the flap of the crotch lower end edge at the back side rear portion, the female material is provided on the other surface side (surface side). The male material and the female material of the fastening tape are brought into contact with each other, and the crotch division part is connected through a separation part where the absorption core inside the diaper does not overlap. According to Patent Document 1, in this way, when an infant is to wear a pants-type diaper, the crotch part of the diaper is divided and opened, and the mother grabs the two toes from there with one hand. It is said that the crotch can be joined after being pulled out and worn. In other words, the normal pants-type diaper cannot be divided into the crotch, so it is necessary to pull out one leg at a time. May pass through the next leg and may not be able to insert both legs indefinitely. The pants-type diaper with the inseam divided is intended to eliminate such inconvenience when the baby is put on a diaper.

  On the other hand, since the unfolded diaper can be divided into the unfolded state around the hip bone, there is no inconvenience when being worn through the foot as described above. However, in a deployable diaper, it may be difficult to place it under the wearer and place it in the proper position. Especially for adults, since the wearer's body is heavy, for example, in the case of a caregiver who needs to be a bedridden person, the diaper that the assistant has lifted and unfolded from his / her waist must be buried under the diaper. If a large adult diaper is difficult to handle, it will be forced to work hard. Moreover, the diaper for adults has a particularly high unit price, and if the diaper is replaced every time it is polluted by urination or the like, it becomes an economic burden for the person requiring assistance or the person who needs assistance. In consideration of this, it is used in combination with an inner pad (urine collecting pad), and if there is some urination, only this inner pad is exchanged, and so on.

  In view of the problems peculiar to the above-mentioned unfoldable diapers, etc., the present invention exhibits extremely high liquid retention when used in combination with an absorbent pad, and facilitates the replacement of the absorbent pad and the diaper. The purpose is to provide excellent diapers or diaper covers.

  The present invention has a front part along the wearer's belly side, a rear part along the back side, and an intermediate part located between the two parts and along the crotch, and is worn in combination with an absorbent pad. The diaper can be divided into an abdominal body and a dorsal body at the intermediate portion, and the abdominal body and the dorsal body are disposed closer to the skin than the both bodies. The above-mentioned object is achieved by a deployable diaper that is detachably joined via a joining member on the back side of the absorbent pad and that is detachably joined and connected to both sides of the waistline of the two main bodies. .

  Further, the present invention has a front part along the wearer's stomach side, a rear part along the back side, and an intermediate part located between the two parts and along the crotch, combined with the absorbent pad The diaper cover can be divided into an abdominal body and a dorsal body at the intermediate portion, and the abdominal body and the dorsal body are on the skin side of the two main bodies. A diaper cover is provided that can be attached and detached through the joining means on the back side of the absorbent pad disposed on the backside, and further joined and connected to both sides of the waist of the two main bodies. It is.

  The unfolded diaper or diaper cover of the present invention is used in combination with an absorbent pad to exhibit extremely high liquid retention, etc., and can be handled lightly by further dividing the unfolded diaper during replacement. It is possible to replace only the main body part and the absorbent pad and to assemble and use it in a desired form at the connecting part, facilitating replacement of the absorbent pad and diaper, etc., and excellent in economic efficiency.

Hereinafter, the developed diaper of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an inside view of a diaper schematically showing a developed disposable diaper for adults, which is a preferred embodiment of the developed diaper of the present invention, in combination with an absorbent pad in a shape opened on both sides of the diaper and opened from a worn state. It is the perspective view seen from. FIG. 2 is an exploded perspective view showing the crotch part of the disposable diaper shown in FIG. FIG. 3 is a plan view schematically showing an absorption pad as one embodiment used in combination with the diaper of the present embodiment as seen from the back surface.

  The deployable diaper 10 of the present embodiment is arranged such that the rear part R of the diaper is arranged on the back side of the wearer, the diaper crotch middle part C is placed along the crotch, and the front part F is applied to the lower abdomen of the wearer. Can be worn. Then, the absorbent pad 20 is arranged in combination with the inner skin side of the diaper 10 to form an integrated unfolded diaper structure, and the long absorbent pad 20 extends from the abdominal side to the back side. Wear alongside. The diaper 10 can be divided at the intermediate portion C. In other words, the abdominal absorbent main body 10F that is the abdominal body that forms the front body of the diaper and the abdominal absorbent main body that is the back body that forms the back body. 10R is combined, and has a structure in which both are connected at the crotch center part C via an internal absorption pad 20. This connected state will be described in detail later. The shape of the diaper 10 connected in this way when expanded and expanded on both sides is the same as a normal unfolded diaper (see FIG. 2). That is, in the extended state, it is long as a whole from the abdominal side to the back side in plan view, and has an hourglass shape with a large and gentle constriction on both sides in the middle width direction. On the other hand, the absorption pad 20 is a belt-like rectangle, and has a shape that is somewhat constricted around the wearer's thigh (see FIGS. 1 to 3).

  When the diaper of the present embodiment is worn, the rear side flap Sr (in the present invention, “flap” means the outer side of the absorbent core material in the diaper body). The portion without the core material extending is referred to. In this embodiment, the flap is composed of a top sheet 1 (1f, 1r) and a back sheet 2 (2f, 2r). On the side, this rear side flap Sr covers the front side flap Sf of the front part F. Fastening tape (male material) 4r attached to the rear side flap Sr is pressed against and attached to the outer surface of the back sheet 2f. The wearing state of the diaper 10 will be described later with reference to FIG. In the present embodiment, the fastening tape 4 (4r, 4f) includes a surface fastener 42 that can be mechanically engaged with a joint surface provided with hook-shaped or T-shaped hooks facing the surface sheet, It consists of the base material sheet 41 which consists of a nonwoven fabric distribute | arranged to the back surface sheet side. And the fastening tape is attached so that the base side of this base material sheet 41 may be pinched | interposed with a surface sheet and a back surface sheet.

  In the present embodiment, the back sheet 2f has a two-layer structure, and is composed of a porous sheet on the side of the absorbent core material 3f (on the wearer's skin) and an exterior sheet on the opposite side of the diaper. This exterior sheet | seat consists of a nonwoven fabric, and functions as a female material which the male material of a fastening tape fastens. The exterior sheet is provided on the outer surface so as to cover the entire surface of the back sheet 2f. Therefore, as described above, the side flap Sr of the back side absorbent main body 10R and the side flap Sf of the ventral side absorbent main body 10F are disposed. The back fastening tape 4r can be engaged at any position on the outer surface of the back sheet 2f of the abdominal absorbent main body. On the other hand, the fastening tape 4f attached to the abdominal absorbent main body 10F in this embodiment is folded inward from the state w extended outward as shown in FIG. It is preferable that the flap Sf is engaged with the inner surface. By doing in this way, the fastening tape 4f which becomes a wearer's skin side is settled well, and it can prevent joining to other members etc. carelessly at the time of attachment or detachment. As will be described later, in the present embodiment, the abdominal absorbent main body 10F and the dorsal absorbent main body 10R have the same structure, and can be used interchangeably. In this case, the functions described above can be used. What is necessary is just to use as a function of an absorptive main body opposite to each other.

After using the unfolded diaper 10 of the present embodiment, the fastening tape 4r on the dorsal side wrapped around the abdomen is peeled off from the outer surface of the back sheet 2f of the abdominal absorbent main body 10F by the reverse procedure. Then, the rear side flap Sr can be opened to unfold the diaper and remove it from the wearer's body.
In the unfolded diaper 10 of the present embodiment, the leg opening Lo is further formed in the vicinity of the waist opening edge 5 (5f, 5r) constituting the waist opening Wo (see FIGS. 2 and 4). A long elastic member such as a rubber string or a urethane sheet band may be disposed in the vicinity of the leg opening edge 11 (11f, 11r). Moreover, you may make it form the standing gather which stands on a wearer's skin surface side and makes a leak-proof wall in the vicinity of the both-sides edge in the width direction of the absorptive core material 3 (3f, 3r). At this time, a liquid-impermeable side sheet may be disposed as a member constituting the flaps on both sides of the diaper body including the standing gathers.

  As described above, the deployable diaper 10 of the present embodiment has the abdominal absorbent main body 10F that forms the front body and the dorsal absorbent main body 10R that forms the back body. The sheet 1 (1f, 1r), the back sheet 2 (2f, 2r), and the absorbent core material 3 (3f, 3r) interposed between the two sheets. At this time, the front sheet 1 (1f, 1r) and the back sheet 2 (2f, 2r) are arranged on the outer periphery of both sheets so as to enclose the absorbent core material 3 (3f, 3r) disposed therein. It is joined. Although this joining method is not particularly limited, it is preferable to join firmly by heat sealing, hot melt bonding, or the like. Furthermore, the diaper of the present embodiment is a body edge that is on the top sheet 1 (1f, 1r) side and on the crotch intermediate part C side when worn on each of the abdominal absorbent main body 10F and the back absorbent main body 10R. The flap 6 (6f, 6r) of the part has a joining member 7 (7f, 7r) (see FIG. 2). The joining member 7 can be detachably attached to an exterior sheet (not shown) made of a non-woven fabric constituting the outer surface of the back sheet 2, but is similarly attached to any other sheet made of a normal non-woven fabric. For example, it can be attached at any location on the topsheet 1 made of non-woven fabric. Therefore, in this embodiment, the joining member 7 can be detachably joined to any position of the absorbent main bodies 10F and 10R. Moreover, as an embodiment different from the above, the joining member 7 may be adhered to only a part of the diaper. Furthermore, as another embodiment, it is good also as an unfolding type diaper cover as the abdominal side main body and back side main body without the said absorptive core material 3. FIG.

The diaper 10 of this embodiment is combined with the absorbent pad 20 as described above, and both the main bodies 10F and 10R are joined and connected via the absorbent pad 20 (see FIGS. 1 and 2). The absorption pad 20 and the connection state through the absorption pad 20 will be described in detail.
In the present embodiment, the absorbent pad 20 is a long absorbent article that is mounted so as to extend from the front part F on the ventral side to the rear part R on the back side through the middle part C of the crotch. Then, absorbent pad joining members 27 (27f, 27r) are disposed at both ends (Tf, Tr) in the longitudinal direction, and one of the joining members 27f is joined to the topsheet 1f of the ventral absorbent main body 10F. The other joining member 27r is joined to the topsheet 1r of the back side absorbent main body 10R. Specifically, the joining member 27 is formed of a planar mechanical fastener, and can be detachably joined to an arbitrary position of the diaper 10 in the same manner as the fastening tape 4 and the joining member 7 of the diaper main body. Therefore, the absorbent pad can be used by being attached to or detached from the absorbent main bodies 10F and 10R, and when only the absorbent pad 20 is soiled, only this pad can be replaced. Further, when the absorbent pad 20 and the diaper 10 are worn in combination, the pad can be worn while being aligned by attaching or removing only the pad portion.

  The absorbent pad in the present embodiment includes a top sheet 21, a back sheet 22, and an absorbent core member 23 interposed between the two sheets, and a pair of side sheets 29 on both sides in the width direction on the top sheet side. Is arranged. This side sheet is bonded and fixed at the upright bases on both side edges in the width direction of the absorbent pad, and the width direction inner end of the side sheet is a free end that is not bonded. Then, an elastic member 28 is disposed in the vicinity of the free end (see FIG. 1), and the standing gather B having a good height is formed by appropriately contracting from the extended state. By doing in this way, it is possible to receive excretion fluid at the excretion point P at the approximate center of the absorption pad and collect it without escaping in the side direction, thereby exhibiting high lateral leakage prevention properties.

  In the present embodiment, as described above, the joining members 27 (27f, 27r) having a long mechanical fastener function in the width direction are provided at both ends in the longitudinal direction of the long absorbent pad, so that the entire surface is provided with this. It is easier to handle than a wide range. Specifically, it has the following advantages. The absorbent pad 20 is usually handled independently of the diaper main body (10F, 10R), and is inserted into the back from the wearer's buttocks, and attached while aligning by wearing or peeling as described above. . For this reason, in order to prevent displacement of the absorbent pad 20 when worn, stable bonding between the absorbent pad 20 and the diaper 10 is required, and ease of wearing when the person is required to wear along an appropriate position. In view of the above, it is preferable not to adhere too strongly or inadvertently. From this point of view, the absorbent pad 20 of the present embodiment is provided with the joining member 27 (27f, 27r) as a pair of elongated belt-like fasteners at both ends in the longitudinal direction. Moreover, it is easy to put a diaper on the absorbent pad by placing it in an appropriate position.

  Further, in the present embodiment, the abdominal absorbent main body 10F and the absorbent pad 20 are connected to the abdominal main body through the joint member 7f, and the back absorbent main body 10R and the ventral absorbent main body 10F are connected to the back main body. It is joined and connected via a joining member. By doing in this way, even if it joins and joins more stably than joining only with the joining member 27 of an absorption pad, even if a wearer turns over or walks, the assembly shape of a diaper and an absorption pad at the time of wear is carried out. Maintained well. In this embodiment, the absorbent core material 3f of the abdominal side absorbent main body, the absorbent core material 3r of the back side absorbent main body, and the absorbent core material 23 of the absorbent pad are mainly arranged for urination and the like. It is made to overlap in the excretion area | region P of the inseam to receive (refer FIG. 1). In other words, in the crotch side region Q of the absorbent main body, the above three layers are laminated (see FIG. 2). By doing so, for example, when there is a large amount of urination when worn for a long time at night, for example, the absorbent main body 10F and 10R surely suppress leakage even when the absorbent pad 20 alone cannot be processed. Can do.

  In the deployable diaper 10 of the present embodiment, as described above, the crotch region Q including the flap 6f on the crotch intermediate portion C side of the abdominal absorbent main body 10F is the crotch side region Q of the dorsal absorbent main body R. It is superimposed. For example, the crotch region Q of the abdominal absorbent main body 10F is folded twice to the back sheet side and is folded in three, and the main body 10F alone is 3 in this portion. A layer may be formed (see the folded region Q ′ indicated by a one-dot chain line in FIG. 2). At this time, the engaging surface of the joining member 7f of the abdominal absorbent main body is folded twice as described above so as to face the exterior sheet of the back sheet 2f. Here, the joining member 7f and the back sheet The outer surface of 2f is joined. Thereby, the shape of the folding region Q ′ is fixed, and it is possible to prevent the portion from being inadvertently shifted and deformed when worn, or the folded state from being released.

And in the part with folding area | region Q 'as mentioned above, the surface sheet 21 of the abdominal side absorptive main body 10F is exposed on the back side, and the joining member 7 of a back side absorptive main body is joined here and connected. can do. The diaper and the absorbent pad assembled in this way have a laminated structure of a total of five absorbent cores in the excretion region P, and can achieve extremely high absorption retention and leakage prevention. This folding method can be arbitrarily determined according to the needs of the wearer in addition to the above-described form, and the number of folding times may be changed or the amount of folding may be adjusted. For example, the folding form may be adjusted depending on the relationship with the excretion point when used for men and when used for women. Moreover, you may adjust this fold amount and change the crotch of a diaper according to a wearer.
By the way, it goes without saying that the crotch part is located in or near a region where urination or the like is concentrated. It is not preferable that there is a separation part in which the absorbent core material is not disposed in that part, which leads to exudation of the excretion liquid, leakage, and poor absorption. According to the present embodiment, since there is the absorbent pad 20, there is no worry that it can be separated from the crotch part, but as described above, the absorbent core material of the absorbent main bodies 10F and 10R also overlaps at the crotch and has a spaced apart part. In addition, leakage and oozing can be more suitably prevented.

  The diaper 10 of this embodiment is divided into the abdominal absorbent main body 10F and the dorsal absorbent main body 10R after the side flaps of both sides are opened and spread as described above and further divided at the crotch part as described above. Can be handled. Therefore, even if a person needs assistance and has a considerable weight, the waist can be lifted and the dorsal absorbent main body 10R can be addressed promptly. In particular, since the diaper of the present embodiment is used in combination with the absorbent pad 20, it has an advantage that the internal absorbent pad can be handled from the crotch side which is divided and opened. At this time, the fastening tape 4 on both sides may be put on and the side flaps may be closed, and the internal absorbent pad that is frequently required to be replaced can be handled by extending the helper's hand from the crotch side, which is highly convenient. . In particular, changing the absorbent pad of a heavy adult caregiver is hard work for a caregiver such as a woman. It is forced to lift the waist of the caregiver and lift it up and lay down with a large and long absorbent pad, but this is greatly reduced, and it can be suitable for nursing care such as bedridden elderly people etc. it can.

  In the deployable diaper 10 of the present embodiment, the abdominal absorbent main body 10F and the dorsal absorbent main body 10R have the same shape and structure. Therefore, both can be divided and handled, and these can be exchanged as appropriate. Therefore, when only one of the two is dirty, it can be dealt with by replacing only one of them, and the consumption of the diaper can be reduced. At this time, depending on the gender and body characteristics of the wearer, the folded end region Q is folded back, and the area that is particularly susceptible to contamination is treated intensively with one absorbent body, and only the dirty absorbent body is replaced. By doing so, the economic efficiency can be further improved. In addition, when stocking a replacement diaper, there is no complication of taking different shapes for the abdominal side and the back side, and the inventory efficiency is good. This is also common and preferable in terms of production efficiency when manufacturing diapers.

  FIG. 4 is a perspective view schematically showing a state where the adult unfoldable diaper 10 of the present embodiment is worn. As shown in the figure, in the diaper 10 of this embodiment, the abdominal absorbent main body 10F and the back absorbent main body 10R are overlapped in the crotch side region Q, and both are detachably joined. Then, the rear side flap Sr is superposed on the front side flap Sf so as to be connected on both sides of the diaper waistline D, and the fastening surface of the rear fastening tape 4r is set to the lower abdomen of the ventral absorbent main body 10F. Near the center, it is brought into contact with the back sheet 2f and joined. At this time, since the outer surface of the back sheet 2f is composed of a non-woven exterior sheet, it can be fastened with a fastening tape. In this part, a landing sheet that particularly improves the detachability of the fastening tape is provided. Also good. Further, an absorbent pad 20 is incorporated in the skin side of the assembled diaper 10.

  The diaper 10 connected in a predetermined position and thus in the mounted state is formed with a waist opening Wo and a pair of leg openings Lo. The diaper 10 of this embodiment is divided and connected so that the circumference around the waist can be adjusted. Therefore, the diaper 10 not only has a degree of freedom in the size around the waist, but also changes the size of the crotch as described above. As it can be divided and connected, there is a degree of freedom in the size of the crotch.

  In the present embodiment, as the top sheet, back sheet, side sheet, and absorbent core material, various materials used in ordinary absorbent articles and the like can be used. At this time, the exterior sheet of the top sheet and the back sheet is preferably a non-woven fabric or the like which is a good female material by itself in consideration of the properties as a female material of the mechanical fastener. As a material for forming the planar fastener or the base sheet used for the fastening tape, a material usually used for this type of article can be used.

  The unfolded diaper of the present invention is not limited to the above-described embodiment, and can be appropriately changed. For example, the bonding member disposed on the crotch part of the main body and the bonding member disposed on the absorbent pad may be made of an adhesive other than the surface fastening tape that enables mechanical desorption as in the above embodiment. It may be a coated film, an adhesive tape, or the like.

  In addition to the two absorptive main bodies as in the above embodiment, other members may be combined and assembled. For example, the ventral and dorsal side flaps Sr and Sf are separably attached to the ventral and spine. It may be used by applying only to those who need it. In addition, members other than those shown in the above embodiment may be used as appropriate. For example, a functional sheet or the like may be interposed between the sheets or members. Further, the unfolded diaper of the present invention is not limited to the disposable diaper for adults as in the above embodiment, but may be a diaper for infants and the like.
