【発明の詳細な説明】 本発明はウエスト部モレ防止及びウエスト部のフィッ
ト性を向上させた構造を有するつかいすておむつに関す
る。Description: TECHNICAL FIELD The present invention relates to a diaper having a structure in which the waist is prevented from leaking and the fit of the waist is improved.

設けられたものである。In general, this type of diaper is conventionally provided with gathers at the crotch portion of the diaper as a measure to prevent leakage, and the wearer's crotch portion is closely attached to the diaper. An absorbent body is provided between a transparent back sheet and a main body composed of the main parts of the absorbent body, and a locking member made of an adhesive tape is provided for fixing to an infant body.

レなどが生じてくる。However, in such diapers, the crotch of the wearer fits and fits the leg circumference, but the infant is lying down because the waist is only fixed to the back sheet of the diaper main body by rigid adhesive tape. In some cases, excrement may leak from the waist. In order to solve this drawback, Japanese Patent Application Laid-Open Publication No. HEI 9-86139 discloses a method in which a stretchable member is attached to the upper part of the absorber of the diaper and on the tape side and stretches along the lateral direction of the back sheet. 58-87
However, this type of diaper uses a general rubber-like elastic body. It is easy to get stuffy and fogging occurs.
又、かかるおむつはテープまでも伸縮性部材で構成さ

る。In addition, since such a diaper is formed of an elastic member even up to the tape, the allowable range of the tape adhesive force required when using the diaper is narrowed, and there is a great difficulty in tape production.

いだし本発明に到達した。The present inventors have conducted intensive studies to improve the disadvantages of these conventional diaper diapers, and found that the backsheet is soft and elastic in a lateral direction, and has a relatively wide elasticity with a nonwoven fabric-like elasticity. By attaching the member, the waist of the diaper is soft, and when attaching / detaching the tape with a relatively large pressure contact area, it expands and contracts integrally with the back sheet, making it easy to attach / detach The present inventors have found that it can be effectively prevented and arrived at the present invention.

かいすておむつを提供するものである。That is, the present invention provides a liquid-permeable top sheet, a liquid-impermeable back sheet, an absorber positioned between the two sheets, and a substantially rectangular shape having a fastener for attaching a diaper. In the diaper, a breathable and elastic band member (3) made of a spunbonded nonwoven fabric made of polyurethane fiber is attached to the back sheet in a lateral direction adjacent to at least one short side end. A diaper having a breathable and stretchable band-shaped member (3) having a width of at least 20 mm that does not overlap with the absorber and a lateral elongation of the backsheet of at least 20%. To provide.

は砂時計等の縦長の形状を有するものも包含する。In order for the stretchable member of the present invention to work effectively on the waist, the portion that does not overlap the absorber is preferably 20 mm or more in width. However, a part of the elastic member may overlap the absorber. In addition, the diaper of the present invention is characterized in that the stretchable member is not stuffy because it is a breathable non-woven fabric. At that time, since the stretchable member and the backsheet fixing the stretchable member expand and contract together, the stretch ratio of the backsheet in the lateral direction is preferably 20% or more. still,
In the present invention, the substantially rectangular chair diaper includes a vertically long shape such as an hourglass.
以下、図面により本発明の実施例について詳細に説明

着剤６による点状又は線状接着が適当である。FIG. 1 is a plan view showing an example of a diaper of the present invention, FIG. 2 is a sectional view taken along the line AA, and FIG.
It is a line sectional view. As shown in FIGS. 2 and 3, this diaper is made of a gas-permeable and elastic band-shaped member (nonwoven fabric-like elastic body) 3 provided between a top sheet 1 and a back sheet 4 to hold an upper absorbent member (tape). ) A portion which is located on the 5 side and does not overlap the absorber 2 along the lateral direction of the back sheet 4 is 20 mm
The width is as described above, or the width of the overlapping portion with the absorber 2 is fixed in a range that does not hinder the expansion of the nonwoven fabric elastic body 3 in at least the lateral direction. As a fixing method, point-like or linear bonding with the adhesive 6 is appropriate.

びである。Since the diaper of the present invention is configured as described above, the nonwoven fabric-like elastic body expands and contracts integrally with the back sheet according to the size of the waist of the user, so that the tape can be easily attached and detached when using the diaper. At the same time, the diaper absorbs liquid in the chair and prevents leakage from the waist when the infant is lying down. Moreover, since the elastic member is a wide non-woven fabric having air permeability compared to a conventional diaper, it effectively prevents stuffiness and rash and fits softly into the user's waist. Become. A urethane spunbonded nonwoven fabric is the most excellent elastic member for achieving such an effect. What is important here is the width of the portion where the elastic member does not overlap the absorber, and the lateral extension of the back sheet that integrally forms the diaper.

に密着させることができ効果的である。From the viewpoint of compressing the wearer, it is important that the elastic member is preferably wide and forms an elastic body having a low elasticity. Therefore, the elastic member of the present invention uses a urethane spun-bonded non-woven fabric widely, and at least 20% of the elastic non-woven fabric is used in order to more effectively configure the expansion and contraction of the waist portion using a conventional rigid tape. It is preferable to combine with a back sheet having elongation.
When it is 20% or less, the nonwoven fabric is torn without exhibiting the above effects, the back sheet is further torn, and the diaper component is removed from the diaper tape portion without having the waist elastic function, and the diaper's original function is Even the function of attaching and detaching by tape may be lost. Such a back sheet is preferably made of polyethylene or the like. or,
For such an effective configuration, it is necessary to keep the absorber away from the elastic member to some extent. When the width of the portion that does not overlap the absorber is 20 mm or more, the elastic member expands and contracts without breaking the absorber, and the diaper waist can be brought into close contact with the wearer's skin, which is effective.

実施できる。As described above, by using the diaper according to the present invention, an effect that cannot be expected from the conventional one is obtained, and it is extremely useful, but the present invention is not limited to only the above description, and Any change can be made within the scope of the gist.
