[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary product, and more particularly to a sanitary product having excellent fit when worn.

[0002]

2. Description of the Prior Art In conventional sanitary articles such as sanitary napkins, vaginal discharge sheets, incontinence pads or disposable diapers, which have a pair of wings perpendicular to the lengthwise direction of the main body on their side edges, It was attached to the crotch part of the to prevent twisting. However,
Even if the sanitary napkin is worn, the body may be moved in order to carry out daily life, so that simply providing a wing has a problem in the followability and fit of the body movement.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to provide a sanitary article having excellent followability to body movements found in daily life and a good fit when worn.

[0004]

In order to solve the above-mentioned problems, the means adopted by the present invention is an absorber having a rectangular shape in a plan view.
Has a main body part in which the wing part and the wing part are overlapped,
The part extends outward from both edges of the center part of the absorber part.
At least a pair of wings is provided, and the pair of wings is a main body.
Elasticity that expands and contracts in the direction orthogonal to the length direction of the part
A member is provided on the wing part, and the pair of wings is provided on the main body part.
It is characterized in that it is made to expand and contract in the width direction .

Further, according to the present invention, the wing portion and the absorber portion are
It is characterized by being adhesively fixed mainly in the range where the elastic member does not exist .

The elastic member is stretched so as to be sandwiched and held between the upper and lower members of the wing portion, or the upper and lower members of the wing portion which sandwich the elastic member can be stretched in a direction orthogonal to the length direction of the main body portion. In addition, the elastic member can be sandwiched and held between the upper and lower members in an unextended state, and three-dimensional gather portions are provided on both side edges of the main body portion, or along the length direction of the main body portion. It is desirable to form the hot-pressed groove within the mounting range of the elastic member in the main body portion.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described in detail below with reference to the drawings. In the figure
(1) shows a catamenial according to the present invention, a pair of out extending outward perpendicular to the length direction of each body portion on the side edge of the body portion (2) forming a rectangular plane (2) wing ( 3) is provided.

As shown in FIG . 3, the main body portion (2) includes an absorbent body portion (7) in which an absorbent body (6) is sandwiched between a surface sheet (4) and a PE sheet (5), and a nonwoven fabric (7). 8) and PE film (9)
Wing portion sandwiched elastic member (10) and (11) the polymerization between
It has a rectangular shape in plan view. Hui
The outside of the ring (11) is located at both sides of the center of the body.
A pair of wings (3) extending in one direction are integrally formed
It In the embodiment, the non-woven fabric (8) and PE film
The elastic member (10) is sandwiched between (9) to form the wing portion (11). The elastic member is sandwiched between two films such as PE.
The wing portion (11) may be formed by sandwiching (10).

The elastic member (10) is made of a flexible elastic material such as film, foam, thread rubber or raw rubber, and the wing portion (11) is arranged in the longitudinal direction of the main body portion (2). The pair of wings (3) are reciprocally urged by contracting and urging them in the orthogonal direction.
Approach. And the absorber part (7) and the wing part (11)
As shown in FIG. 4, the absorber part (7) and the wing part (11)
Central portion partially adheres by a hot-melt (12) of, or by bonding them integrally in the longitudinal direction both end portions and a central portion, as shown by hatching in FIG. 5, the elastic member (10) Wing by elasticity of (3) Secure elasticity.
In addition, as shown in FIG. 6, the absorber part is formed only at both ends in the length direction.
You may adhere (7) and the wing part (11). FIG. 7 corresponds to FIG.
FIG. 5 is a cross-sectional view taken along the line BB, and the reference numeral (5) is a PE sheet.
And is connected to the non-woven fabric indicated by reference numeral (8) at the joint portion (16).
Are combined. In Fig. 7, the shaded area is the joint,
The central part is in a non-bonded state.

Further, the elastic member (10) may be a plurality of rubber threads juxtaposed as shown in FIG. 8, or two elastic films as shown in FIG. It may be parallel, or as shown in FIG. 10, one elastic film may be attached to the main body portion so as to give a desired stretching effect.

Further, the pair of films forming the wing portion (11) have the same plane shape as the main body portion (2) as shown in FIG. 11, or the absorber portion as shown in FIG.
The elastic member (10) is made by shortening the film (8) located on the (7) side.
It may be configured to perform only the fixing action of.

Furthermore, when fixing the elastic member (10),
With the elastic member (10) in the stretched state,
The upper and lower members of the wing portion (11) for sandwiching and holding the upper and lower members (8) and (9) of 1) or for sandwiching the elastic member (10).
(8) When the (9) is constituted by extendable in a direction perpendicular to the longitudinal direction material of the body portion (2), the upper and lower members of the elastic member (10) in a non-stretched state (8) (9) between The wings (3) may be expanded and contracted by sandwiching the ends and adhering and fixing both ends thereof.

On the other hand, as shown in FIG. 13, the absorber part (7)
When the PE film (5) is folded inward and the elastic body (13) is sandwiched between the folded edges to form the solid gather portions (14) on both side edges of the main body portion (2), the prevention effect against leakage is further improved. Can be higher.

Further, as shown in FIGS. 14 and 15, the thermal compression groove (15) along the length direction of the main body portion (2) is provided in the absorber portion.
When it is provided in (7), the elasticity of the wings (3) can be enhanced, and the twisting prevention effect and the leakage prevention effect of the main body portion (2) can be further enhanced. still,
When the hot-pressed groove (15) is provided in this way, it is not necessary to bond the central part of the absorber part (7) and the wing part (11) to each other because the effect of preventing twisting is enhanced, but FIG. When the inner side of the groove (15) is fixed by hot melt or heat sealing as shown in (4), the anti-twist effect can be further enhanced.

[0015]

According to the sanitary article of the present invention, even when the wing is fastened to the crotch portion of the undergarment to prevent twisting, the wing expands and contracts in the width direction of the main body portion in accordance with the movement of the body. To do. Therefore, the followability to the movements of the body accompanying daily life with the sanitary article attached is enhanced, and the fitability when attached is improved.
