Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable diaper, and more particularly to a disposable diaper that facilitates a wearing operation.

[0002]

2. Description of the Related Art There are various types of disposable diapers for babies, elderly people, etc. As shown in FIG. 7, both sides of a central portion in a longitudinal direction are concavely curved to face each other, and an absorber (1) is provided on the inner surface side. A crotch pad (2), an abdominal part (4) at one end in the longitudinal direction connected to the crotch pad, to which a frontal tape (3) linear in the width direction is fixed, and the other end in the longitudinal direction The unfoldable disposable diaper, which comprises fastening tapes (5) and (5) at the opposite ends in the width direction, respectively, and a back part (6),
It is widely used today because of its low cost.

In order to use such a diaper, the wearer is usually laid on his back, the back side (6) of the diaper is placed against the wearer's back, and the crotch support (2) is placed at the crotch position. Then, the abdominal part (4) is applied to the abdominal side, and then the tip adhesive surface of the fastening tape (5) projecting from the diaper sheet member is removably adhered to the frontal tape (3).
It is worn in the form of pants.

[0004]

However, such a disposable diaper is usually worn with the abdominal part (4) protruding forward as shown in FIG. Therefore, the positional relationship between the fastening tape (5) and the frontal tape (3) is such that they cross and overlap as shown in FIG. 9, and the front end adhesive surface of the fastening tape (5) is attached to the frontal tape (3).
When attaching the frontal tape (3), the margin S of the space in the width direction of the frontal tape (3) becomes small. For this reason, if the wearing operation is not carefully performed, the adhesive surface of the fastening tape (5) will protrude from the frontal tape (3), and the adhesive strength will be weak, so that the diaper cannot be worn for a long time. On the other hand, it is conceivable that the width of the frontal tape is sufficiently widened, but this is problematic due to the high cost.

[0005]

SUMMARY OF THE INVENTION The present invention has been developed to solve the above-mentioned problems, and as a result, has developed a disposable diaper in which a fastening tape can be easily attached.

That is, in the disposable diaper of the present invention, both sides of the central part in the longitudinal direction are concavely curved to face each other, a frontal tape is fixed in the width direction of the front part, and a fastening tape is fixed to both ends in the width direction of the rear part. In a disposable diaper, at least both ends of the frontal tape are bent to the rear side, and the frontal tape includes a straight portion and a sloped end linearly inclined to the rear side of both ends. Things are valid.

[0007] Another disposable diaper according to the present invention is a diaper for infants or toddlers, wherein the disposable diaper has a width.
A frontal tape comprising a straight portion of 30 to 60 mm, a total length of 160 to 290 mm and a length of 4/11 to 7/11 of the total length, and an inclined end portion inclined at the rear side at an angle of 1 to 15 ° at both ends of the straight portion. It is a disposable diaper excellent in wearing workability characterized by using diapers. Further, a frontal tape in which at least both end portions are curved in a rear row is also effective.

As described above, according to the present invention, a conventional frontal tape is formed by bending both ends of the frontal tape toward the rear side where the diaper fastening tapes (5) and (5) are provided as shown in FIG. is there. By doing so, as shown in FIGS. 2 and 3, when the diaper is applied to the body and the fastening tape (5) is attached to the curved both ends of the frontal tape (10), the fastening tape ( 5) overlaps substantially parallel to both ends b of the frontal tape, so that the entirety of the fastening tape (5) is easily and reliably stuck, and the wearing operation is facilitated.

A disposable diaper as shown in FIG. 1 for an infant or baby having a shape in which both ends of the frontal tape (10) are linearly inclined has a width of 30 to 60 mm and a total length of 160 to 290 mm as the frontal tape. 4/11 of the total length
It is preferable to use a frontal tape having a straight portion a of about 7/11 and an inclined end b that is inclined rearward at an angle of 1 to 15 ° at both ends thereof.

[0010] Thus, the frontal tape width is 30 to 60 mm
If it is smaller than 30 mm, it will not be possible to obtain sufficient adhesive strength, and at the same time, it will be difficult to perform tape fastening work, 60 mm
If it is wider, the cost is increased and the members are wasted. The preferred width dimension is between 40 and 50 mm.

The total length of the frontal tape is 160 to 290 m.
m, but it is large enough to be attached with fastening tape, considering the body shape of infants and infants. It is more preferably 170 to 260 mm.

[0012] Then said the straight part a frontal tape length L ₁ was 4 / 11-7 / 11 of the total length, 4/11 If shorter is too long the length of the inclined end portion This is because both ends move too far to the rear side of the diaper, which makes it difficult to attach the fastening tape. Further, if it is larger than 7/11, the inclined end becomes too short, and the effect of the present invention cannot be obtained.

The inclination α of the inclined end from the straight line portion is 1 to
The reason why the angle is set to 15 ° is that if the angle is smaller than 1 °, the effect of the present invention is not sufficiently exerted. If the angle is larger than 15 °, both ends move excessively to the rear side of the diaper, so that it becomes difficult to attach a fastening tape. Because.

Furthermore a fixed location L ₂ in the longitudinal direction from the diaper front edge of frontal tape is internally provided waist elastic member for close contact with the waist portion of the diaper to the wearer's waist at the front end portion of the front of the diaper About 30 if
If the waist elastic member is not provided, it is suitably about 5 mm or more. The fastening position of the fastening tape (5) from the rear edge of the diaper is moved back and forth in accordance with the longitudinally fixed position of the frontal tape. The size of the target disposable diaper for infants and babies is P = 350-600 mm and Q = 260-400 mm.

[0015]

An embodiment of the present invention will be described below.

As shown in FIG. 4, the total length is 400 mm and the total width is 290 mm
The both sides of the crotch abutment (2) at the center in the longitudinal direction are concavely curved to face each other, and both ends in the width direction of the front part (the abdominal part (4)) are at the rear part (the dorsal part (6)). It is bent at an angle of 5 ° to form inclined end portions b, b, and a frontal tape (10) having a straight portion a having a length of 109 mm is fixed at a distance of 8 mm from the front end edge, and further fixed on the back side portion (6). 25mm wide and 30 projecting length at each end in the width direction
A disposable diaper for babies to which mm fastening tapes (5) and (5) were fixed was produced. When the diaper was put on the baby's crotch and worn, the protruding portions of the fastening tapes (5) and (5) could be overlapped with sufficient margin in the inclined end b of the frontal tape (10). Was.

As another shape of the frontal tape (10), as shown in FIG. 5, a straight portion a at the center and curved ends c, c which are curved to the back side at both ends thereof are extended. Things are also available. Alternatively, a frontal tape (10) whose entire surface is curved as shown in FIG. 6 may be used.

[0018]

As described above, according to the present invention, when the diaper is used, the fastening tape overlaps with the frontal tape in parallel, so that the entire surface of the fastening tape is securely and easily placed in the frontal tape surface and adhered. This has the effect of making it easier to wear.
