Description

The present invention relates to a deployable wearing article.

Conventionally, various proposals have been made regarding attachment means for wearing articles such as expandable diapers. For example, in a deployable diaper, the diaper can be worn by engaging a fastening tape extending from the side edge on the back side with a loop tape on the ventral side of the non-skin side.
Apart from this, in addition to the fastening tape, the diaper described in Patent Document 1 includes a temporary fastening band attached in the shape of a belt along the width direction of the diaper. The temporary fastening band is used by being pulled in the same direction as the fastening tape and wrapped around the wearer's waist.

Japanese Patent Application Publication No. 11-70143

When putting on a diaper provided with fastening tapes, the baby is laid down on the back part of the diaper and the ventral part of the diaper is pulled up to engage the fastening tapes with the loop tapes. At that time, if the baby moves (for example, flops his legs or rolls over and sleeps), it may not be easy to put the baby on, and it may take some time to put it on. Depending on the degree of movement, it may not fit properly and may lead to urine leakage. In this regard, in the diaper described in Patent Document 1, since the temporary fastening band is used in the same operation method as the fastening tape, the diaper still suffers from the above-mentioned problems when worn.
In view of the above points, the present invention relates to a deployable wearing article that has good operability and can be worn comfortably even when the wearer moves.

The present invention includes a ventral part, a crotch part, and a dorsal part arranged on the ventral side, crotch part, and dorsal side of the wearer, and corresponds to a direction in which the ventral part, the crotch part, and the dorsal part are connected. A deployable wearing article having a longitudinal direction extending along the longitudinal direction and a width direction perpendicular to the longitudinal direction, comprising a pair of fastening tapes extending from both side edges of the dorsal side part in the width direction, and a non-woven article on the ventral side part. A temporary fastening tape and a temporary loop tape are provided on the skin side of the dorsal side part and the ventral side part at positions facing each other when the deployable wearable article is worn. Provided is a deployable wearable article having:

The deployable wearing article of the present invention has good operability and can be worn comfortably even when the wearer moves.

FIG. 2 is a plan view schematically showing the non-skin side of the expandable diaper shown in FIG. 1. FIG. FIG. 3 is a plan view showing the positional relationship between the longitudinal center of the fastening tape and the longitudinal region of the temporary fixing loop tape in the back side of the expandable diaper.

EMBODIMENT OF THE INVENTION Hereinafter, the expandable wearing article according to the present invention will be described in detail with reference to the drawings based on an example of an expandable diaper that is a preferred embodiment thereof.

In the present invention, the side that contacts the wearer's skin is referred to as the skin side or skin side, and the side opposite to this is referred to as the non-skin side or non-skin side. These terms are used to indicate the relative positional relationship in the structure of the absorbent article, even for members that do not have a surface that comes into contact with the wearer's skin. Further, when worn, the direction located on the ventral side of the wearer is referred to as the front, and the direction located on the back side of the wearer is referred to as the rear. The normal direction of the front or back surface of an absorbent article is referred to as the thickness direction.

FIG. 1 shows a state in which a deployable diaper 10 (hereinafter also simply referred to as diaper 10) of the present embodiment is deployed and viewed from the skin side 10A. Here, the unfolded state refers to a state in which the diaper 10 is spread out into a flat shape by stretching each part. In this state, the diaper 10 is divided into a ventral part F, a crotch part C, and a dorsal part R, which are arranged on the wearer's skin side, crotch area, and back side, respectively. Moreover, the diaper 10 has a longitudinal direction Y corresponding to the direction in which the abdominal part F, the crotch part C, and the back part R are connected, and a width direction X that is orthogonal to the longitudinal direction Y. The abdominal part F, the crotch part C, and the back part R correspond to each part of the diaper 10 divided into three equal parts in the longitudinal direction Y. In addition, the side opposite to the skin side 10A of the diaper 10 shown in FIG. 1 is referred to as the non-skin side 10B (see FIG. 2).

The diaper 10 includes an absorbent body 3 that absorbs and retains excretory fluid as a component. A liquid-permeable top sheet 1 is arranged on the skin side of the absorbent body 3, and a leak-proof back sheet is arranged on the non-skin side of the absorbent body 3. The top sheet 1 and the back sheet 2 are longer than the absorbent core 3 in the longitudinal direction Y and the width direction X. Furthermore, side sheets 4 are laminated to extend outward in the width direction while covering both sides of the top sheet 1 in the longitudinal direction Y. Furthermore, elastic members 91 forming waist gathers are arranged at the ends of the back side R in the longitudinal direction Y, and elastic members 92 forming leg gathers are arranged at the left and right ends of the crotch part C in the width direction X. There is. On the inner side of the side sheet 4 in the width direction X, an elastic member 93 that forms a three-dimensional gather that comes into contact with the vicinity of the wearer's groin region is disposed. These components can be formed from a variety of materials commonly used in absorbent articles.

The diaper 10 has a shape in which the crotch portion C is narrowed in the width direction, and the abdominal portion F and the crotch portion R are relatively protruded from the crotch portion C in the width direction when viewed from above. This protruding part is called the flap part. The flap portion is a portion located outward in the width direction X of the absorbent body 3 in the ventral side portion F and the dorsal side portion R, and is a portion that does not include the absorbent body 3. The flap parts of the ventral part F are called ventral flap parts 11, 11, and the flap parts of the dorsal part R are called dorsal flap parts 12, 12.

The diaper 10 has a pair of fastening tapes 13, 13 extending outward in the width direction X from both side edges of the back side portion R, that is, the ends of the back side flap portions 12, 12 in the width direction X. The diaper 10 also has a loop tape 14 on the non-skin side 10B of the abdominal part F, as shown in FIG. The loop tape 14 has a loop that engages the pin that the fastening tape 12 has. The pair of fastening tapes 13, 13 can be pulled outward in the width direction X of the dorsal part R, wound around the ventral part F, and removably engaged with the loop tape 14.

In addition, the diaper 10 has a temporary fastening tape 15 and a temporary loop tape 16 on the skin side 10A of the back side part R and the ventral side part F. The temporary fastening tape 15 and the temporary loop tape 16 are arranged at positions facing each other when the diaper 10 is worn, that is, when it is folded in half for wearing. The temporary fixing loop tape 16 has a loop that engages a pin that the temporary fastening tape 15 has. As a result, the temporary fastening tape 15 and the temporary loop tape 16 can be removably engaged with each other.

In the present embodiment shown in FIG. 1, the temporary fastening tape 15 is placed on the ventral side F, and the temporary loop tape 16 is placed on the back side R, but the present invention is not limited thereto. The temporary fastening tape 15 may be placed on the back side R, and the temporary loop tape 16 may be placed on the ventral side F. However, in a normal tape diaper, the fastening tape 13 is folded into the flap portion when the diaper is packed into a packaging bag. At that time, in order to stabilize the fastening tape 13 in the packaging bag by engaging it with the temporary fixing loop tape 16, the arrangement shown in FIG. 1 is preferable.

The diaper 10 has the temporary fastening tape 15 and the temporary loop tape 16, so that even if the wearer (for example, an infant) moves, the diaper 10 has good operability and can be easily worn by the wearer. .
Specifically, first, with the back part R of the diaper 10 fixed along the back of the wearer who is lying down, the ventral part F in front is slightly pulled to cover the wearer's ventral side. This operation is accompanied by an action of pressing the wearer's leg with the ventral part F. This makes it possible to suppress movement of the wearer's legs to some extent.
Subsequently, the diaper 10 can be temporarily fastened by engaging the temporary fastening tape 15 and the temporary fastening loop tape 16 while covering the wearer's abdominal side with the ventral side portion F of the diaper 10. At this time, the abdominal part F of the diaper 10 suppresses not only the movement of the wearer's legs, but also the movement of the wearer's torso (for example, movements such as turning over in bed), and the diaper 10 is held against the wearer. can be fitted.
Next, with the wearing position determined by temporary fixing, the pair of fastening tapes 13, 13 are wound around the abdominal part F and engaged with the loop tape 14, thereby completing the wearing of the diaper 10.
Through this series of operations of the diaper 10, the person wearing the diaper (for example, a guardian) can securely position and fix the diaper 10 around the wearer's legs and torso while restraining the wearer's movements. . In particular, operations up to temporary fixing can be performed smoothly without changing the hand holding the diaper 10. As a result, the diaper 10 has good operability and can be easily worn by the wearer even when the wearer (for example, an infant) moves.

The temporary fastening tape 15 and the temporary loop tape 16 are preferably present in a region outside the absorbent core 3 in the width direction X of the diaper 10. That is, one pair of temporary fastening tape 15 and one temporary loop tape 16 are provided on the left and right flap portions (ventral side flap portions 11, 11, dorsal side flap portions 12, 12) on the outside of the absorbent body 3 in the width direction X. It is preferable that the For example, as shown in FIG. 1, a pair of temporary loop tapes 16, 16 are arranged on the left and right dorsal flap parts 12, 12 (skin side 10A) outward from the absorbent body 3 in the width direction An example is a configuration in which a pair of temporary fastening tapes 15, 15 are arranged on the ventral side flap parts 11, 11 (skin surface side 10A). Further, the temporary fixing loop tape 16 and the temporary fixing fastening tape 15 may be arranged interchangeably as described above.
Thereby, it is possible to prevent the temporary fastening tape 15 and the temporary fastening loop tape 16 from coming into contact with the skin when the diaper 10 is temporarily fastened. Also, pinch the pair of temporary fastening tapes 15 (or temporary fastening loop tapes 16) on the ventral side part F of the diaper 10, and then press the pair of temporary fastening loop tapes 16 (or temporary fastening tapes 15) on the back side R. By pulling it to the position (for example, in the pulling directions P and P shown in FIG. 1), temporary fixing can be performed more smoothly. As a result, the diaper 10 can further improve the above-mentioned operability and can be worn more reliably.

Furthermore, it is preferable that a region 17 whose rigidity changes in the width direction X exists in the region between the temporary fastening loop tape 16 (or the temporary fastening tape 15) and the absorbent core 3 in the back side portion R. Further, it is preferable that the region 17 where the stiffness changes has a stiffness change point 18 where the stiffness is partially increased by joining the constituent members. This point of change in rigidity 18 can be formed by an embossed part that joins the constituent members (for example, the top sheet 1, the back sheet 2, and the side sheet 4), or an adhesive part coated with a hot-melt adhesive or the like. can. Further, the stiffness change point 18 may be a portion that is partially made thicker than the surrounding area depending on the number of layers of the constituent members or the like.
As a result, the back flap portions 12, 12 of the diaper 10 are easily bent appropriately, and the temporarily fastened loop tape 16, temporarily fastened fastening tape 15, and fastening tape 13 are prevented from coming into contact with the wearer's skin. be able to.

The region 17 where the stiffness changes in the width direction X and the stiffness change point 18 may further extend in the longitudinal direction Y of the diaper 10 as long as they are arranged on the back side R and can achieve the above effect. . Moreover, in the back side part R, it may be arranged not in the whole but in a part.
For example, as shown in FIG. 1, the region 17 where the stiffness changes in the width direction X and the point of change in stiffness 18 may extend from the back side portion R to the crotch portion C and the ventral side portion F. Further, the region 17 where the stiffness changes in the width direction X and the stiffness change point 18 may not be arranged in the crotch part C, but may be arranged in part or all of the dorsal part R and the ventral part F ( (not shown).

Furthermore, in the diaper 10, it is preferable that the temporary fixing loop tape 16 has a larger area than the temporary fixing fastening tape 15. Thereby, temporary fixing can be performed more reliably during a series of operations for putting the diaper 10 on the wearer. Note that the area of the temporary fixing loop tape 16 and the area of the temporary fixing fastening tape 15 are compared between tapes that face each other when the diaper 10 is worn.
From the viewpoint of performing reliable temporary fixing, the area of the temporary fixing loop tape 16 is preferably more than 1 times the area of the temporary fastening tape 15, more preferably 1.5 times or more, and even more preferably 2 times or more.
Further, the area of the temporary loop tape 16 is preferably 60 times or less than the area of the temporary fastening tape 15, more preferably 50 times or less, and still more preferably 40 times or less, from the viewpoint of increasing the stability of engagement of the flap portion. preferable.

In addition, in the present embodiment shown in FIG. It is preferable that it overlaps with the region 16R (see FIG. 3). That is, it is preferable that the center 13M of the fastening tape 13 in the longitudinal direction Y is in the range from the edge 16T on the dorsal side of the region 16R to the edge 16B on the ventral side. Note that the center 13M of the fastening tape 13 in the longitudinal direction Y refers to the center of the longest part of the fastening tape 13 in the longitudinal direction Y.
Thereby, in the diaper 10 before use, the fastening tape 13 can be engaged with the temporary fixing loop tape 16 and stored. In addition, when wearing the diaper 10, when pulling the fastening tapes 13, 13 after temporarily fastening and winding them around the abdominal part F, the temporarily fastened portions of the diaper 10 (the temporarily fastening tape 15 and the temporary fastening loop tape 16) (the part where it is engaged) can be fitted appropriately along the wearer's torso. Thereby, generation of a gap between the diaper 10 and the wearer's waist can be effectively suppressed.

As shown in FIG. 1, the fastening tape 13 is not limited to the case where one each is arranged on the left and right back side flap parts 12, 12, but two or more fastening tapes 13 may be arranged on each of the left and right back side flap parts 12, 12. When two or more fastening tapes are arranged, it is preferable that the center 13M of each fastening tape 13 overlaps with the region 16R in the longitudinal direction Y of the temporary fastening loop tape 16 arranged on the back side portion R.

Furthermore, it is preferable that the direction of the pins of the temporary fastening tape 15 is the longitudinal direction Y. As a result, the pins of the temporary fastening tape 15 can be naturally engaged with the temporary loop tape 16 during the above-described temporary fastening operation, and displacement after temporary fastening is less likely to occur.
From the same viewpoint, it is preferable that the loops of the temporary fixing loop tape 16 be oriented in the width direction X.
A pin is a protrusion of a cap portion of a micro-sized hook present on a fastening tape, and the protrusion direction of this cap portion is the "pin direction." In addition, if protrusions of the cap portion are seen in multiple locations, large and small, the above-mentioned "pin direction" is determined at the point where the protrusions are the largest. "Loop orientation" refers to the fiber orientation of the fibrous material that makes up the loop tape. The engagement between the temporary fastening tape 15 and the temporary loop tape 16 is achieved by fitting the male fastening material formed by the protrusion of the cap portion and the female fastening material made of a fiber material. Since the projecting portion is on the longitudinal side and the orientation rate of the loop in the width direction is higher, the engagement can be more firmly achieved during temporary fixing.

On the other hand, it is preferable that the direction of the pins of the fastening tape 13 is the width direction. Further, it is preferable that the loops of the loop tape 14 are oriented in the longitudinal direction Y.

As described above, the deployable diaper 10 of this embodiment has good operability and can be worn comfortably even when the wearer moves.
