Abstract

PURPOSE:To effectively utilize both an indication tape and a waist periphery elastic member by attaching each indication tape to the opposed side in a front side area of a diaper, separating a half area of the inside in the lower direction from the lower side edge of the waist periphery elastic member of the diaper body, and also, positioning at least a part of a half area of the outside on the upper face of an outside surface sheet on the upper face of the elastic member. CONSTITUTION:In an indication tape 17, its center area 17a is separated in the lower direction from the lower side edge of a waist periphery elastic member 4 in a front side area 2 of a diaper body 1, and the upper side part of both outside areas is positioned on the upper face of an outside surface sheet 9 on the upper face of a non-flexible part 4a of the elastic member. An inside half area 7a of the indication tape 7 is detached from a flexible axis of the waist periphery elastic member 4, therefore, it hardly receives directly strong contraction force of the waist periphery elastic member 4, and wrinkled are hardly derived. An outside half area 7b of the indication tape is positioned in the flexible axis of the elastic member, but in both outside areas of the waist periphery elastic member, its contraction force is weaker than that in its center area, therefore, wrinkles are hardly derived.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disposable diaper, and more particularly, a tape fastener attached to the outer surface of the front region of the diaper for attaching and detaching the free end region of the tape fastener attached to the opposite side of the rear region of the diaper. Regarding the instruction tape.

(Prior art) Conventionally, an indicator tape that also serves as reinforcement for the outer sheet indicates a target area such as a scale for adhering the free end area of a tape fastener according to the size of the waist circumference of a 1.7# user. (
Target tape (also called target tape) or disposable diapers that are attached to the front area of the diaper are in practical use. Furthermore, in a diaper to which an elastic member is attached along the waist circumference of the diaper to tighten the waist circumference, when viewed from the front side of the diaper, the indicator tape is , is located in contact with or close to the lower edge of the elastic member.

(9f, problem to be clearly solved) In order to fully utilize the tensile stress of the external member around the waist of the diaper to tighten the waist v11 to the relevant part of the n car name, the free end area of the tape fastener Preferably, the elastic member is bonded to the area where the p+1 member lies, so that a normal tensile force is applied to the elastic member. However, since the free end area of the tape fastener is shifted downward from the area where the indicator tape or external member to be attached lies,
The free end region of the tape fastener will be glued in this position, or the said stress of the elastic member cannot then be fully utilized.

In particular, in the case of R grooves that are usually large in size around the waist, even though they adhere to the protruding end of the tape fastener or the outer and upper part of the front area of the diaper, the indicator tape or the lower part that deviates from that part Since it is located on the side, it is impossible to use the instruction tape.

In addition, the indicator tape in conventional diapers has not been given special consideration to its relationship with the elastic member around the waist, and as a result, the function of the indicator tape may be damaged due to the strong contractile force of the elastic member. There are many things that are derived from ken.

[1] An object of the present invention is to provide an indicator tape so that even wearers with waist circumference sizes ranging from the lower limit size to the upper limit size can effectively utilize the indicator tape and all of the waist circumference members. Our goal is to provide disposable diapers that are equipped with the following methods.

(Means for Solving the Problem) In one configuration aspect of the diaper of the present invention to achieve the above object, each indicator tape is attached to the opposite side of the front area of the diaper, and the front area is viewed from the front. When viewed, the inner half region in the longitudinal direction of the diaper main body or the outer half region in the longitudinal direction of each indicator tape is spaced apart from the fa edge of the elastic member surrounding the waist in the front region of the diaper main body in the direction C. At least a portion of the area is located on the upper surface of the outer sheet on the upper surface of the elastic member.

In another constructional aspect of the undeveloped diaper for achieving the above-mentioned objective II, an instruction tape is attached in series on opposite sides of the front area of the diaper, and when the front area is viewed from the front, , at least one of the central region in the longitudinal direction of the indicator tape or the front region of the diaper body is spaced downwardly from the lower edge of the surrounding elastic member, and at least the front region of the indicator tape in the longitudinal direction. The - section is located on the upper surface of the outer sheet on the upper surface of the elastic member.

In a perverse embodiment, a non-stretchable region is provided at the outer end of the elastic member in the longitudinal direction, and at least a portion of the outer region of the indicator tape is provided on the upper surface of the non-stretchable region. or located.

(Example) Referring to Eko, an example of diapers for undiagnosed 1y1 is explained in theory 1!
1, the result is as follows.

1l-2f is a perspective view of the diaper in an assembled state. The diaper body l consists of a front region 2 and a rear region 3, and an external member 4.5, which will be described later, is attached along each of the waist circumference and chest circumference, and an opposing member in the rear region 3. Tape fastener 6 attached to the side
and an indicator tape 7 attached to the opposite side of the front region 2.

FIGS. 2 and 3 are front and rear views of the diaper, respectively. The diaper body 1 includes a liquid-permeable inner sheet 8, a liquid-impermeable outer sheet 9, and a liquid-absorbent core 10 interposed between the inner sheet 8 and the outer sheet 9.

The waist circumference and chest circumference elastic members 4.5 are made to expand and contract in respective directions and are bonded between the inner sheet 8 and the outer sheet 9 with an adhesive.

However, non-stretchable portions 4 are provided at both lengthwise ends of the waist-surrounding elastic member 4.
It has a. In order to provide the non-stretchable portion 4a, it is sufficient that the portion is not stretched as described above.

Both indicator tapes 7 have an appropriate distance IJL between these opposing inner ends.
It is adhered to the outer surface of the outer sheet 9 in the front region 2 with an adhesive so that the outer sheet 9 is formed in the front region 2. The instruction tape 7 is the front area 2
The indicator tape is elongated in the transverse direction, and its upper and lower side edges are curved in a gentle curve, and the indicator tape is inclined upward from the inner end to the outer end in the length direction of the indicator tape. Further, the indicating tape 7 is spaced downward from the lower edge of the waist circumference elastic member 4 in the approximately inner half region 7a or front side region 2 in the length direction of the indicating tape, and the length of the indicating tape is The upper side of the substantially outer half region 7b in the direction of non-stretching +'ffl of the elastic member
4a is located on the upper surface of the outer sheet 9 at the top 1nj.

FIG. 4 is a front side view of a diaper according to another embodiment of the present invention. In this embodiment, the indicator tape 17 is straight at the inner end of both indicator tapes 7 and has a width of iJ! The central region 17 in the length direction of the indicator tape corresponds to
Its inner and outer regions 17b are each inclined upward from a. Further, the instruction tape 17 is rolled from the lower edge of the waist circumference elastic member 4 in the central region 17a or the front region 2 of the diaper main body I toward the lower blade, and the upper part of the inner and outer regions is Outer sheet 9 on the upper surface of the non-stretchable portion 4a of the elastic member
It is located on the top of the .

The elastic member 4.5 is made of polyurethane, rubber, etc., the tape fastener 6 is made of high quality paper, nonwoven fabric, etc., and the inner sheet 8 is made of nonwoven fabric, etc.
The outer sheet 9 is made of a porous plastic film, water-repellent nonwoven fabric, etc., and the indicator tapes 7 and 17 are made of a plastic film, high-quality paper, nonwoven fabric, etc. Although not shown, on the surface of the indicator tape 7.17, a scale or the like is displayed to indicate the target area to which the free end region of the tape fastener 6 is to be bonded.

(Operations of the Embodiment) In the diaper of the present invention having the above-mentioned configuration, as shown in FIG. When assembling and removing, the free end area of the tape fastener 6 is separated from the indicator tape 7.

Furthermore, when wearing a diaper, the waist area bullet +h
S material 4, tape fastener 6 and instruction tape 7 (17
) will be explained with reference to Figures 2 to 4.
If the waist circumference of the wearer is small, the free end area of the tape fastener 6 is glued to an appropriate part of the inner half area 7a of the indicator tape 7 (center area 17a of the indicator tape 17), while the wearer's waist circumference is small. If the waist circumference is large, the free end area of the tape fastener 6 should be aligned with the outer half area 7b of the tape 7.
(Inner and outer regions 17b of indicator tape 17) will be adhered to appropriate locations.

In the waist circumference elastic member 4, the tensile stress, in other words, the contractile force, is concentrated more strongly than in the central region or the inner and outer regions thereof. By the way, the inner half region 7a of the indicator tape 7 (the central region 17a of the indicator tape 17) is spaced downward from the lower edge of the central region where the contractile force of the waist member 4 is strong, that is, Since the waist νn is off the elastic axis of the suburban member 4, the free end area of the tape fastener 6 is connected to the inner half area 7a of the indicator tape 7 (the center area l7a of the indicator tape 17).
), the strong contractile force of the waist-surrounding elastic member 4 is less likely to be directly applied to the adhesive tape 7 (17).
It is less likely to be derived from modesty that inhibits the function of the person. On the other hand, the outer area 7b of the indicator tape 7 (both outer areas 17b of the FF1 indicator tape 17) is the 1lff four elastic member 4.
The elastic member 4 overlaps the upper surface of both outer regions, that is, is located on the elastic axis of the elastic member, or both outer regions of the waist-surrounding elastic member 4 have a weaker contractile force than the central region. Or less likely to be derived. In particular, the waist circumference elastic member 4
If the non-stretchable region 4a is provided at the hQ end of the indicator tape 7, the outer half region 7b of the indicator tape 7 (both outer regions 17
The derivation of ken in b) is considerably less.

(Effects of the Invention) According to the diaper of the present invention, since the indicating tapes are arranged as described above, the indicating tapes can be placed on the waist circumference, the wearer from the lower limit size to the upper limit size, or the free end area of the tape fastener. Can be glued. Moreover, even if the free end region of the tape fastener is attached to any part of the indicator tape, it will be strongly affected by the contractile force of the waist-surrounding elastic member and the function of the indicator tape will be affected. Not much.

In this way, although the structure is in the cylinder, it can be used for rightward movement without interfering with the functions of the waist-surrounding elastic member and the indicator tape, which is extremely beneficial in practical use. be.
