Description

  The present invention relates to a deployable diaper.

  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 on which the absorbent core does not extend at the edge of the portion divided at the crotch, and a male material of the fastening tape is provided on one side (back side) of this flap portion. Yes. 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). Then, the male material and female material of the fastening tape are brought into contact with each other, and the crotch division portion is connected via a separation portion where the absorbent 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 it can be pulled out and then joined to the inseam 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 diaper, an object of the present invention is to provide a unfoldable diaper that has a high ability to absorb liquids and the like, facilitates replacement of the diaper, and is excellent in economy.

  The present invention is a deployable diaper having 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, The diaper can be divided into an abdominal absorbent main body and a dorsal absorbent main body at the intermediate portion, and the both absorbent main bodies are respectively a top sheet, a back sheet, and an absorbent interposed between the two sheets. A core, and at least one of the absorbent main body has a connecting member that can be attached and detached at an arbitrary position of the other absorbent main body at the crotch side edge, and the abdominal absorbent main body and the back side absorbent The main body achieves the above-described object by a deployable diaper that is joined at the intermediate portion so that the absorbent cores of the two absorbent main bodies overlap in plan view by the joining member.

  The unfolded diaper of the present invention can be handled lightly by dividing the unfolded diaper, and can be used by assembling it into a desired form at the connecting part or replacing only the dirty main body part if necessary. It exhibits high absorption retention of liquids, etc., and facilitates changing diapers and is economical.

Hereinafter, the developed diaper of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view seen from the inside of a diaper schematically showing an unfolded disposable diaper for adults, which is a preferred embodiment of the unfolded diaper of the present invention, in a shape in which both sides of the diaper are unfolded and opened slightly from the wearing state. is there. FIG. 2 is an exploded perspective view showing the disposable diaper shown in FIG.

  The deployable diaper 10 of the present embodiment has a rear part R of the diaper arranged on the back side of the wearer so that the middle part C corresponding to the crotch of the diaper is along the crotch, and the front part F is below the wearer. Can be worn against the abdomen. The diaper 10 can be divided at the middle part C. In other words, the abdominal absorbent main body 10F that forms the front body of the diaper and the back absorbent main body 10R that forms the back body are combined, and the two are separated from each other. It has the structure connected with the part C. 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.

  When the diaper of the present embodiment is worn, the rear side flap Sr further disposed on the back side of the back side absorbent main body 10R (in the present invention, the “flap” refers to the outer side of the absorbent core in the diaper main body. In this embodiment, the flap is composed of a top sheet 1 (1f, 1r) and a back sheet 2 (2f, 2r). I, 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 this embodiment, the fastening tape 4 (4r, 4f) includes a planar fastener 41 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 42 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 42 may be pinched | interposed with a surface sheet and a back surface sheet. The base sheet 42 may be joined only to the back sheet instead of the embodiment.

  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 3f (on the wearer's skin) and an exterior sheet on the outer 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. This 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 Sf of the ventral absorbent main body is covered with the side flap Sr of the back absorbent main body 10R. When wearing in a covering manner, the fastening tape 4r on the back side can be engaged at any location on the outer surface of the back sheet 2f of the abdominal absorbent main body 10F. 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 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 3 (3f, 3r) interposed between the two sheets are configured. At this time, the top sheet 1 (1f, 1r) and the back sheet 2 (2f, 2r) are joined at the outer periphery of both sheets so as to enclose the absorbent core 3 (3f, 3r) disposed therein. Has been. 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 this embodiment is a body edge portion that is on the side of the top sheet 1 (1f, 1r) and on the crotch 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) has a joining member 7 (7f, 7r) (see FIG. 2). As described above, the joining member 7 can be detachably attached to an exterior sheet (not shown) made of a non-woven fabric that constitutes the outer surface of the back sheet 2. For example, it can be engaged at any location of the surface sheet 1 made of nonwoven fabric. Therefore, in this embodiment, although the joining member 7 may not be able to be joined to the whole diaper, it can be detachably joined to any position of the absorbent main bodies 10F and 10R.

  In the present embodiment, the abdominal absorbent main body 10F and the dorsal absorbent main body 10R are joined and connected to each other by the joint members 7 of the both, and the absorptive core 3f and the dorsal side of the abdominal both absorbent main bodies 10F. The absorbent core 3r of the absorbent main body is overlapped. And the both sides of the waistline side of both absorptive main bodies 10F and 10R are as above-mentioned so that the area | region divided by the front part F and the rear part R may comprise the waist part D (refer FIG. 4) of a diaper when it mounts | wears. The unfolded diaper has a waist opening and a pair of leg openings.

  3 is an enlarged cross-sectional view taken along line III-III shown in FIG. In the deployable diaper 10 of the present embodiment, the crotch folded end region Q including the flap 6f on the crotch intermediate part C side of the abdominal absorbent main body 10F is folded twice into the back sheet side and is folded in three. There are three layers. 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. As a result, the folded shape of the folded end region Q is fixed, and this portion can be prevented from being inadvertently shifted and deformed when worn, or the folded state being released.

  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. In addition, without folding, as shown in FIG. 2, the abdominal absorbent main body 10F having the elongated shape shown by the two-dot chain line may be overlapped and connected to the back absorbent main body 10R. For example, when using as a diaper for women, it is good also as an embodiment piled up by this extended shape in relation to an excretion point.

  In the diaper 10 of the present embodiment, the crotch side folded end region Q of the abdominal absorbent main body 10F is folded back to the back side as described above, and the top sheet portion 1f directed to the back side has the back side absorbent main body 10R. Both absorptive main bodies 10F and 10R are connected by abutting and joining the joining member 7r. This connection position can be appropriately determined in consideration of the physique of the care recipient and the convenience of changing diapers. The diaper may be joined and connected on the folding edge side than the one shown in the figure, or the diaper may be a long diaper. Alternatively, the diaper may be joined and connected to the back sheet 2f of the abdominal absorbent main body 10F across the folding region Q. May be. Such adjustment may be adjusted according to the amount of folding of the folded end portion Q described above.

  According to the diaper 10 of the present embodiment, adjustment of the size and shape of the diaper adapted to the wearer's body as described above, which was difficult if the conventional inseam shape is fixed, and further this embodiment Thus, it is possible to perform alignment with respect to the absorption point P (see FIG. 1) of a man who is slightly shifted to the ventral side. As a result, it is possible not only to respond appropriately to the wearer and individual body, but also because of the dimensional freedom, the burden of storing and preparing diapers of various sizes in nursing care facilities is reduced. preferable.

  In the present embodiment, as described above, the crotch lower end region Q of the abdominal absorbent main body 10F is folded twice, and a three-layer structure is formed at that portion, and further, a total of four layers are formed by lamination with the back absorbent main body 10R. (See FIG. 3). Therefore, the absorbent core 3f overlaps the four layers, and the absorbable amount of the portion is greatly increased as compared with other portions (in the present invention, the overlap of the absorbent core means that the absorbent core overlaps when viewed from the plan view of the article, that is, from the direction d) That means there is an overlap.) Thus, even if urine or the like is intensively excreted in this portion, it can be suitably absorbed and retained. For example, when it is used as a diaper for men, the excretion point P of a portion where urination is particularly a little on the front side of the ventral side can be applied to this four-layer portion, and the excretion can be suitably handled. 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 portion in which the absorbent core is not disposed in that portion, which leads to exudation of the excretion fluid, leakage, and poor absorption. According to the diaper 10 of the present embodiment, the absorbent core overlaps at the crotch and does not have a separation portion, and the above can be suitably prevented.

  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.

Further, the diaper 10 according to the present embodiment can be handled by dividing the both side portions and then developing the diaper 10 at the crotch portion, and separating the abdominal absorbent main body 10F and the back absorbent main body 10R. 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. Then, as a separate operation, the abdominal absorbent main body 10F can be placed at a predetermined position, and the groin can be put on by connecting the crotch in a calm state. At this time, the fastening tape 4 around the waist may be stopped and fixed before the crotch part is joined and connected.
In this way, according to the present embodiment, the work of raising and lifting the waist of a person requiring assistance and spreading and spreading a large one-piece diaper is greatly reduced, which is suitable for the care of a bedridden elderly person, for example. It can correspond to.

  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, the diaper 10 of the present embodiment is configured such that the crotch lower end region Q of the abdominal absorbent main body 10F is folded and the outer side is covered with the crotch side edge of the back absorbent main body 10R. Are detachably joined. Then, the rear side flap Sr is overlapped 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, they are brought into contact with the back sheet 2f. 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.

  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, various materials that are used in ordinary absorbent articles and the like can be used as the top sheet, the back sheet, and the absorbent core. 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 7 (7f, 7r) disposed in the crotch part of the main body is not only a planar fastening tape that enables mechanical detachment as in the above-described embodiment, but also a coated film of adhesive, an adhesive It may be a tape or the like. As described above, it is preferable that the joining member has the same shape provided on the same surface so that the absorptive absorbent main body 10F and the dorsal absorbent main body 10R can be replaced with each other. However, it is more preferable to dispose the joining member on the top sheet side. By doing in this way, careless joining to a wearer's clothing etc. is prevented and it becomes easy to change a diaper. Moreover, when using in combination with an inner pad, the joining member which does not participate in the connection of absorptive main bodies can also be connected and fixed with this inner pad.

  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.
