1: wearing article 4: elastic member

6: top sheet 7: back sheet

The present invention relates to a disposable wear article of the present invention, and more particularly, to a disposable wear article such as a diaper, an incontinence pants, and training pants.

This type of worn article conventionally has an elastic member attached to its leg circumference. Generally, the elastic member fixes the stretched elastic member to at least one of the top and the backsheet with an adhesive.

Depending on the article, for example, in disposable diapers, regardless of whether the wearer is a male or a female, the excrement is generally from the lower part of the diaper of the diaper, ie, from both sides of the site, in relation to the position and orientation of the urinary system. This is easy to leak.

Therefore, it is preferable that the diaper be configured so that the pressing area by the elastic member in the lower portion of the leg circumference can be made wider than other portions of the leg circumference.

However, in the diaper conventionally proposed and practically used, there is no consideration in changing the arrangement gap in the longitudinal direction of the elastic member composed of a plurality of lines.

The present invention provides an article in which the arrangement intervals of the respective elastic members composed of a plurality of lines in each of the leg circumference portions are changed in their length direction in order to keep the wearing state of the article satisfactorily and prevent leakage of the excretion liquid. The task is to provide.

The present invention for solving the above problems is a one-time use each attached elastic member consisting of a plurality of lines along the leg circumference formed in an arc shape on both sides of the lower crotch region located between the front and back regions of the top sheet and the back sheet It is intended for wearing articles.

In the present invention relating to the above object, the arrangement interval of the plurality of elastic members in each of the leg circumferences is widest in the longitudinal center portion of the elastic member, and gradually narrowed from the central portion to the both ends thereof. It is characterized by the configuration.

In the article according to the present invention having the above constitution, the arrangement intervals of the plurality of elastic members in each of the circumferential portions of the legs are defined in the longitudinal center portion of the elastic member, that is, in the center of both sides of the crotch region of the article. Compresses the wearer's skin with the widest range in the area.

This ensures that pressure is widely distributed at both centers of the crotch region so as not to cause pain in the wearer's area and to prevent excretion from leaking from both edges of the crotch region of the article.

EXAMPLE

An embodiment of a wearable article of the present invention will be described below with reference to the drawings.

1 is a perspective view of the wearing article 1. The article 1 has a leg circumference 2 and a waist circumference 3, and attaches elastic members 4, 5 to it, respectively.

2 shows an exploded perspective view of the article 1. The grief (1) comprises a longitudinal stretch, a permeable top sheet (6) and a longitudinal stretch, an impervious backsheet (7), an absorbent core (8) on a mat or sheet, and an elastic member (4, for leg and waist). 5) consists of. At approximately the side edge of the sub-crotch region 12 located between the front and back regions 10, 11 of the top and back sheets 6, 7, an arcuate concave incision edge 13, the leg circumference 2, is provided. It is being formed. The elastic member 4 for leg circumference is composed of a plurality of string-like elastic materials, and the backsheet is formed in accordance with the shape of the concave edge 13 of the backsheet 7 in a state where it is elongated at a desired magnification. It is fixed to the hot-melt adhesive region 14 coated on the inner surface. The elastic member 5 for the waist circumference is composed of a tape-shaped elastic material, and the inner surface of the backsheet is formed in accordance with each end of the front and rear zones 10 and 11 of the back seat 7, which is the waist circumference 3. The hot melt adhesive (not shown) applied to the hot melt adhesive region (not shown) applied to the elastic member 5 itself is fixed along each stage.

3 is a plan view showing an example in which each elastic member 4 is attached to the continuous backsheet 7. While moving the continuous backsheet 7 at a given speed in the longitudinal direction thereof, the continuous backsheet (with a predetermined interval in the longitudinal direction on the opposite side along the longitudinal direction of the upper surface (inner surface) of the continuous backsheet 7) The adhesive region 14 on the upper surface of 7) is formed.

Meanwhile, the shovel support portion for the elastic member formed in the vicinity of the distal end of the first and second traverses (not shown) while moving and extending the plurality of continuous elastic members 4 in the same direction as the continuous backsheet 7. Inserts are supported by a plurality of guide holes in parallel.

Arrangement intervals of a plurality of guide holes in the shovel support portions of the first and second traverses (three in the embodiment) are the central portions in the longitudinal direction of the elastic member 4 shown in FIG. The arrangement interval is the same as that of the arrangement interval shown in FIG. Further, the first and second traverses are each the width W from the starting position P1 on the continuous backsheet 7 to the turning position P2 and from the turning position P2 to the starting position P1, respectively. The reciprocating motion is performed at right angles with respect to the opposite side region.

The arrangement intervals of the plurality of continuous elastic members 4 inserted into the guide holes of the shovel support portions of the first and second travises are different from the arrangement intervals of the guide holes when the shovel support portions are positioned at the starting position P2. A part of each continuous elastic member 4 (refer to the region indicated by reference numeral 4a in FIG. 3) is bonded to the adhesive region 14 while being kept the same, and each shovel support portion is bent from the starting position P1. It gradually narrows down as it moves to the position P2, and in this state, a part following the part of each bonded continuous elastic member 4 is bonded to the adhesive region 14.

Further, each continuous elastic member 4 has a slightly higher elongation as the shovel support moves from the starting position P1 to the bending position P2. As a result, the elongation of each continuous elastic member 4 is shown in FIG. Also in the site | part 4a shown in the figure, it is the lowest and gradually increases from this site | part 4a to the site | part 4b. This causes the traverse to forcibly turn to the side of the backsheet 7 for each continuous elastic member 4 which extends at a given elongation rate and runs in a straight line along the longitudinal direction of the continuous backsheet 7. This is because the continuous elastic members 4 are elongated as they move from the starting position P1 to the bending position P2, respectively, by the resistance of.

However, this depends on the traveling speed in the longitudinal direction of each continuous elastic member 4 and the moving speed in the transverse direction of the traverse. When the starting position and the retracted position of the respective insertion supports are reversed, that is, when the retracted position P2 is set to the starting position and the starting position P1 is set to the retracted position, each elastic member 4 is positioned from the position P2. As it moves to P1, the elongation increases slightly, and as a result, the elongation of each continuous elastic member 4 is the highest in the site 4a, and from the site 4b to the site 4b. Gradually decreases toward).

The non-bonded portion 4c of each continuous elastic member 4 instantaneously draws the trajectory of the curved state as shown in FIG. 3 according to the position of the traverse, and contracts immediately after passing the traverse to extend the length of the continuous backsheet 7. Parallel to the side edge along the direction.

The traverse may be controlled by a cam mechanism so that the continuous elastic member 4 supported by the traverse follows the curved shape of the adhesive region 14 on the continuous backsheet 7.

As shown in FIG. 3, each elastic member 5 is constituted by one line, and the upper surface of the continuous backsheet 7 is adhered to the upper surface of the continuous backsheet 7 after or before bonding the continuous elastic member 4 to the upper surface of the continuous backsheet 7. Hot melt adhesive applied to the hot melt adhesive region (not shown) applied to the upper surface of the continuous backsheet 7 and extended to be positioned across it at a given position in the longitudinal direction of the adhesive member 5 itself (not shown). Is omitted).

Originally, each elastic member 5 may be composed of a plurality of blades, such as each elastic member (4).

Although not shown, the core 8 is an upper surface of the continuous backsheet 7 between each continuous elastic member 4 facing the transverse direction of the continuous backsheet 7, and the length of the continuous backsheet 7. A hot melt adhesive is disposed between the elastic members 5 facing each other with or without the hot melt adhesive.

The top sheet 6 is hot melted on the bottom surface (inner surface) of the continuous back sheet 7 in which the core 8 is intermittently arranged, in which the top sheet 6 is used in the manufacturing process of the article shown in FIG. The continuous adhesive is coated by coating the continuous adhesive with the mold adhesive intermittently to form a continuous filler.

The continuous stacked body constitutes a unit stacked body forming an individual article by cutting the elastic member 5 along the widthwise virtual line 16 which divides the elastic member 5 in the longitudinal direction of the continuous laminate in FIG. By this cutting, the unbonded part 4c of each continuous elastic member 4 is contracted.

The single-laminated laminate is composed of the article 1 shown in FIG. 1 by folding two pieces in the longitudinal direction at the center thereof and joining both edges thereof by heat seal or sonic seal means. However, the present invention is not limited to forming an article in a pant or brief shape, and as described above, the unit stacking agent is folded in two in the longitudinal direction at the center thereof, and the two side edges are not bonded by a heat-sealing means. Like an open diaper, a fastening piece such as a pressure-sensitive tape fastener is attached to both sides of the rear region 11 (see FIG. 2) of the unit stacking material, and the fastening part fastens the waist circumference of the unit stack (article). You may do so. In addition, depending on the article, the core 8 may not be provided. The topsheet 6 has a longitudinally stretchable nonwoven fabric, the backsheet 7 has an impermeable elastomeric sheet or a laminate of it and a longitudinally stretchable nonwoven fabric, and the core 8 has a mixture of flap pulp, superabsorbent polymer particles, and synthetic fibers. For the elastic members 4 and 5, natural rubber and synthetic rubber can be used, respectively.
