JP7229832B2 - Packaging bag for absorbent articles - Google Patents

Description

TECHNICAL FIELD The present invention relates to a packaging bag for containing absorbent articles such as pants-type disposable diapers and tape-type disposable diapers.

A gusset bag is generally used as a packaging form for a large number of disposable diapers. Furthermore, in recent years, so-called compaction packaging, in which disposable diapers are packed in a compressed state, is widely used in order to increase the number of disposable diapers that can be stored in one bag.

Packaging bags in which such disposable diapers are compressed and packaged are displayed in stores, and consumers acquire (purchase) the displayed packaging bags.

The size of the disposable diaper contained in the packaging bag, such as S size, M size, . These sizes are determined, for example, by the wearer's waist length or waist length. For example, for pants-type disposable diapers, if the wearer's waist length is within the range of 50 cm (lower limit) to 70 cm (upper limit), the consumer acquires (purchases) a packaging bag labeled S size.

Some consumers or wearers do not know the girth length of the wearer, and may hesitate whether to obtain the S size or the M size. In this case, the waist length of the wearer may be measured with a tape measure or the like, but it is troublesome and time-consuming for the wearer to wear thin clothes or to try on the clothes for the measurement. In addition, there is a problem that some wearers are shy about wearing light clothing or trying on the clothing.

Patent document 2 is a technique for easily selecting a desired absorbent article even for a visually impaired person.
JP 2018-102845 A JP 2011-184076 A JP 2009-269622 A

Therefore, the main object of the present invention is to allow the consumer to visually or sensuously select the suitable size of the absorbent article worn by the wearer.

The present invention, which has solved the above problems, is as follows.

<First Aspect>
A packaging bag having a substantially rectangular parallelepiped shape in which absorbent articles are accommodated,
The packaging bag is
It has three perimeter lengths: an outer perimeter length that rotates in the vertical and width directions, an outer perimeter length that rotates in the vertical and depth directions, and an outer perimeter length that rotates in the width and depth directions;
The absorbent article has a longest perimeter length out of the three perimeter lengths that is longer than the remaining two perimeter lengths,
The absorbent article is worn by a wearer whose waist length or waist length is within the range from either one of the remaining two outer circumference lengths to the longest outer circumference length. A packaging bag for absorbent articles characterized by:

In a substantially rectangular parallelepiped packaging bag containing an absorbent article of a predetermined size, the applicable range of the girth length of the absorbent article of the same predetermined size is defined by two outer circumference lengths out of three outer circumference lengths orthogonal to each other. represents. A consumer can grasp the outer circumference visually or sensuously by looking at the packaging bag or picking it up, and obtains an absorbent article of a size suitable for the wearer by comparing with the waist length of the wearer. It has the effect of being able to (purchase). In addition, the wearer can acquire (purchase) an absorbent article of a desired size by looking at the packaging bag or placing it against the body even while wearing clothes, without having to measure his/her own waist circumference. It's good, and you don't have to be embarrassed because you don't have to dress lightly or try it on. In this regard, Patent Document 1 is a technique related to a packaging bag for absorbent articles, but the size suitable for the absorbent article worn by the wearer (for example, S size, M size, L size, LL size, other sizes, etc.) It does not have the purpose of allowing the consumer to visually or sensuously select the size that the wearer wears from among them. Further, Patent Document 3 relates to a technique for easily measuring the size, but does not relate to a technique for visually or sensuously grasping the outer circumference like the present invention.

<Second Aspect>
In addition to the first aspect,
In the packaging bag, the remaining two outer peripheral lengths are different lengths,
The absorbent article is worn by a wearer whose waist length or waist length is within the range from the shortest outer circumference to the longest outer circumference.
Aspects can be mentioned.

If the wearer's waist circumference is equal to or more than the shortest outer circumference of the packaging bag and equal to or less than the longest outer circumference of the packaging bag, the absorbent article accommodated in the packaging bag has a size suitable for the wearer. In addition, it is possible to prevent the wearer from acquiring (purchasing) an absorbent article having a size that deviates from the waist length or waist length of the wearer.

<Third Aspect>
In addition to the first aspect,
the remaining two perimeter lengths are equal to each other;
Aspects can be mentioned.

In this configuration, there are two perimeter lengths instead of three. For example, if the short perimeter length is the lower limit length of the compatible size of the absorbent article, and the long perimeter length is the upper limit length, the purchaser can compare the perimeter length of the packaging bag with the waist length or waist length. become easier. The purchaser acquires (purchases) an absorbent article having a suitable size within a range of not less than the short outer circumference and not more than the long outer circumference.

<Fourth Aspect>
In addition to the first aspect,
The packaging bag is
The outer circumference length in the vertical direction and the width direction is the longest,
Aspects can be mentioned.

With this form, the entire surface of the packaging bag becomes the maximum area. In a situation where packaging bags containing various absorbent articles are displayed in stores, the form in which the front surface of the packaging bag has the largest area stands out and attracts the attention of consumers.

<Fifth Aspect>
In addition to the first aspect,
The outer surface of the packaging bag is provided with an information display section displaying information that the size of the absorbent article worn by the wearer can be confirmed by the outer peripheral length of the packaging bag.
Aspects can be mentioned.

A consumer who visually recognizes the information display part can acquire (purchase) an absorbent article of a desired size by comparing the outer circumference length of the packaging bag and the wearer's waist length or waist length. has the effect of

<Sixth Aspect>
In addition to the first aspect,
The advertisement medium is equipped with an information display unit that displays information that the size of the absorbent article worn by the wearer can be confirmed by the outer circumference length of the packaging bag, and is sold.
Aspects can be mentioned.

As described above, a consumer who visually recognizes the information display part can acquire (purchase) an absorbent article of a desired size by comparing the outer circumference length of the packaging bag and the wearer's waist length or waist length. It has the effect of knowing.

As described above, according to the present invention, there are advantages such as allowing the consumer to visually or sensuously select the suitable size of the absorbent article worn by the wearer.

(Definition of terms, etc.)
In this specification, referring to FIG. 1, the direction connecting the front surface 3 and the rear surface 4 is referred to as the depth direction, which coincides with the x-axis. The direction connecting the left side surface 2a and the right side surface 2b is called the width direction, and is assumed to coincide with the y-axis. The direction connecting the upper surface 5 and the lower surface 6 is referred to as the vertical direction, and is assumed to coincide with the z-axis. "Girth length" refers to the length around the waist of the wearer and/or absorbent article (particularly pants-type disposable diapers). "Waist length" refers to the length around the waist of the wearer and/or absorbent article (particularly tape-type disposable diapers). "Perimeter length" refers to the circumference along the outside of an object. For example, the outer peripheral length of the packaging bag is the outer peripheral length that rotates in the vertical direction and the width direction when the packaging bag is set up with the handle portion, which is the part where the packaging bag is held by hand or slung over the shoulder, is up. , the length of the perimeter around the vertical direction and the depth direction, and the length of the perimeter around the width direction and the depth direction. As a specific example, when viewed from the front (when viewed in the x-axis direction), the outer circumference that rotates in the vertical direction and the width direction is the widthwise right side along the top surface 5 from the center of the top surface 5, bends to the right side surface 2b, and bends to the right side. Proceeds downward in the vertical direction along the surface 2b, bends to the lower surface 6, advances to the left in the width direction along the lower surface 6, bends to the left side 2a, advances upward in the vertical direction along the left side 2a, bends to the upper surface 5, and upper surface 5 It means the shortest length (the length of one round) to reach the center of the upper surface 5 by proceeding to the right side in the width direction along. Similarly, the outer peripheral length in the vertical direction and the depth direction and the outer peripheral length in the width direction and the depth direction also refer to the length of one round. In the illustrated example, the rectangular parallelepiped packaging bag has 8 corners at right angles, 12 sides with straight lines, and 6 planes, but is not limited to this form. For example, the corners may be rounded as shown in FIG. 16, or the sides and faces may be curved. Adjacent faces may not be adjacent to each other on the same side, and adjacent bulging faces may be rounded without forming a side. Regarding the upper surface, the outer circumference length shall be taken into consideration in a state in which the upper surface 5 and the upper end portion 7 are folded into substantially the same plane shape. Consider the outer circumference length in the state of being folded into a planar shape.

Regardless of the above, the outer circumference of the packaging bag is the same when the handle is laid down or upside down. It can be represented by the outer circumference length and the outer circumference length in the width direction and the depth direction.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in further detail below based on embodiments shown in the drawings. 1 to 4, 6 and 7 show a packaging bag 1 according to the present invention. This packaging bag 1 is a so-called side fold type gusset bag. However, the packaging bag 1 is not limited to this, and may be a so-called front and rear folding gusset bag. Both ends of the cylindrical plastic tube in the width direction are folded inward by folds 2c along the longitudinal direction to form gussets, and the upper end portion 7 is cut to a predetermined length (the upper end edge and the lower end edge of the upper end portion 7 in the illustrated example). are sealed by fusing or bonding. At the time of packaging, the absorbent article is inserted from the lower end portion 8, and the upper edge of the lower end portion 8 (boundary line between the lower end portion 8 and the lower surface 6) is sealed to form a rounded, substantially rectangular parallelepiped packaging bag. Left side 2a, right side 2b, front side 3, rear side 4, top side 5 and bottom side 6 are thus formed. Further, the upper end portion 7 formed by sealing the upper and lower edges is formed with a grip portion (also referred to as a hand hole 9) for passing a hand in the depth direction at the center portion in the width direction. Of course, the packaging bag 1 of the present invention is not limited to this form, and as shown in FIG. It is possible to adopt an appropriate form such as a form attached by an appropriate connecting means such as. As for the material of the packaging bag 1, a plastic film is generally used, but a sheet material such as paper or a non-woven fabric, or a composite sheet material thereof may be used.

Inside the packaging bag 1, absorbent articles 110 are accommodated in an appropriate arrangement state. For example, a disposable diaper includes an absorbent main body portion, which is a portion in which an absorbent body is interposed between a liquid-permeable top sheet forming a body-side surface and a liquid-impermeable sheet located on the outer surface side, and the absorbent main body portion. Side flaps 29, which are portions extending from both side edges of the absorbent body portion and which do not have an absorbent body, and portions which are directed from the front and rear side ends of the absorbent main body portion, and which have an absorbent body. It has an end flap 30 which is a part that it does not have. Among absorbent articles, in the case of tape-type disposable diapers and pants-type disposable diapers, the entire outer surface of the absorbent main body and the side flaps is formed by the exterior, and the exterior is placed under the wearer like a so-called diaper cover. It covers the waist length from the abdomen to the buttocks and the entire crotch area. In addition, a crotch portion C2 (C2a) facing the wearer's crotch, a ventral portion Fr (F) extending forward from the crotch portion C2 (C2a), and a rear portion extending from the crotch portion C2 (C2a) It consists of a dorsal part Ba (B). Such an absorbent article 110 is generally folded in two with the front and back facing each other, or folded in three with the front and back facing the center, and packaged, and in some cases, folded in four or more. Sometimes it is done. (Because both sides of the front body and the back body of the underpants-type disposable diaper are joined together, the product is folded in two.) If the side flaps are large, the side flaps 29 (29a) are folded. are folded inward along the vicinity of the sides of the absorbent body. In the packaging of the absorbent article 110, usually, a large number of such absorbent articles 110 are gathered, and the aggregate is packed by stacking and compressing the flat portions thereof. In this case, it is preferable to package the diaper so that the plane direction of the diaper is parallel to the side surface of the packaging bag 1, but the depth direction of the diaper is along either the vertical direction or the depth direction of the packaging bag 1. good too. Moreover, as shown in FIG. 2, this assembly may be stacked in two layers, stacked in one layer, or stacked in three layers for packaging.

As the material of the packaging bag 1, plastic films such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and nylon, which are usually used for packaging, can be used singly or as a composite material. In the field of absorbent articles, polyethylene films are widely used, and among them, flexible LDPE (low density polyethylene: density 0.900 to 0.925 g/cm 3 ) and MDPE (medium density polyethylene: density 0.925 g/cm ³ ) are preferable. 925-0.940 g/cm ³ ) is preferred. The thickness of the film is preferably about 40-80 μm.

In one example, the consumer or wearer selects the fit size by girth length for pants-type disposable diapers and by waist length for tape-type disposable diapers. However, the present invention is not limited to this, and the consumer or wearer may, of course, select a pants-type disposable diaper or a tape-type disposable diaper based on the waist length or the waist length. The embodiment of the absorbent article 110, mainly the pants-type disposable diaper 100, will be described in detail below. The detailed embodiment also applies to the tape-type disposable diaper 100a, and in this case, the "length around the waist" can be read as "the length around the waist".

(Absorbent article size)
The absorbent article 110 is manufactured in multiple sizes to fit the body shape of the wearer. A large number of absorbent articles 110 of the same size are assembled, layered so as to match the plane portions, and compressed to form an aggregate package. Absorbent articles 110 (for example, pants-type disposable diapers and tape-type disposable diapers) are manufactured in a plurality of sizes, for example, sizes such as S size, M size, L size, and LL size. Of course, sizes smaller or larger than these can also be manufactured. The pants-type disposable diaper 100 of S size is designed to be worn by a wearer whose waist length is within the range of 50 cm at the lower limit to 70 cm at the upper limit. Needless to say, when worn, the leakage of excrement is reliably prevented, and the wearer does not feel discomfort. Similarly, the M size pants-type disposable diaper 100 is for wearers whose waist length 30L is about the lower limit of 60 to the upper limit of 85 cm, and the L size absorbent article 110 has the waist length 30L of about the lower limit of 75 to the upper limit of 110 cm. For certain wearers. Also, LL size and larger sizes may be designed for wearers corresponding to those sizes.

Therefore, the wearer selects the absorbent article 110 having a size that matches the waist length (or waist length) of the wearer.

(packaging bag size)
All absorbent articles 110 contained in one packaging bag are of the same size. For example, as for the absorbent articles 110 of S size, an aggregate of the absorbent articles 110 of the same S size is accommodated in one packaging bag 1 . The packaging bag 1 of the present embodiment may or may not display the size of the absorbent article 110 being packaged. Specifically, on the outer surface of the packaging bag 1 containing an aggregate of S-size absorbent articles 110, a letter, a symbol, or the like representing the size such as "S" or "S size" may be displayed. You don't have to. Similarly, on the outer surface of the packaging bag 1 containing absorbent articles 110 of other sizes such as M size and L size, characters, symbols, illustrations, etc. representing the corresponding size may or may not be displayed. good too.

In the packaging bag 1, the longest outer circumference length among the three outer circumference lengths (11xy, 11yz, 11zx) is longer than the remaining two outer circumference lengths. Then, it is worn by a wearer whose waist length (or waist length) is within the range from either one of the remaining two outer peripheral lengths of the packaging bag 1 to the longest outer peripheral length. A form of the packaging bag 1 in which the absorbent article 110 is housed can be exemplified. In addition to this form, the remaining two outer circumference lengths are mutually different lengths, and the wearer is the waist length within the range from the shortest outer circumference length to the longest outer circumference length of the packaging bag 1. The form of the packaging bag 1 in which the absorbent article 110 attached to is accommodated can be illustrated. Here, the lower limit of the waist length (or waist length) of the absorbent article 110 of a specific size is the lower limit waist length (or lower limit waist length), and the upper limit is the upper limit waist length (or upper limit waist length). ). Then, the waist length (or waist length) of the absorbent article 110 is included in the range from the lower limit waist length (or lower limit waist length) to the upper limit waist length (or upper limit waist length). A person can wear this specific size absorbent article 110 . In this form, when the packaging bag 1 is picked up and compared with the wearer's waist length, if the wearer's waist length is mistakenly compared with the outer circumference length of the packaging bag 1, which is the second shortest, the result is this product. , there is no problem. Since the acquired waist length (or waist length) of the wearer who wears this product is within the range of the lower limit and upper limit of the same specific size, the product can be used without problems.

The dimensions of the packaging bag 1 can be appropriately determined for the absorbent articles 110 of S size, M size, L size, LL size, smaller or larger sizes, and the S size will be described below as an example. . The S-size pants-type disposable diaper 100 is intended for wearers whose waist length is about 50 cm (lower limit) to 70 cm (upper limit). In this case, the shortest outer circumference of the packaging bag 1 for the S size is the lower limit of the waist length of the S size pants-type disposable diaper 100, 30L, and the longest outer circumference of the packaging bag 1 is the length of the S size pants-type disposable diaper 100. The dimensions of the packaging bag 1 can be determined so that the upper limit of the waist length is 30L'.

In addition, the packaging bag 1 having the longest outer peripheral length 11xy in the width direction and the depth direction and the shortest outer peripheral length 11xz in the vertical direction and the depth direction is packed with an S size pants-type disposable diaper 100. When packaging the aggregate, it can be done as follows. The shortest outer circumference length 11xz is 50 cm (the same length as the lower limit waist length 30L), and the longest outer circumference length 11xy is 70 cm (the same length as the upper limit waist length 30L'). 1 may be defined. As another form, for example, a packaging bag 1 (see FIG. 8) having the longest outer peripheral length 11yz in the vertical direction and the width direction and the shortest outer peripheral length 11xy in the width direction and the depth direction (see FIG. 8). can present the form of

Furthermore, the configuration of the packaging bag in which the remaining two peripheral lengths are equal to each other is preferable. In this form, there are two types of outer circumference lengths. For example, the outer peripheral length 11xy can be set to the same length as the lower limit waist length 30L of the S size pants-type disposable diaper 100, and the outer peripheral length 11yz can be set to the same length as the upper limit waist length 30L'. Since the packaging bag 1 has two types of outer circumference lengths, a person who intends to obtain the product can easily select whether the size is suitable for the wearer to wear when the product is picked up. In addition, the outer circumference length 11xy can be set to the same length as the upper limit waist length 30L' of the S size pants-type disposable diaper 100, and the outer circumference length 11yz can be set to the same length as the lower limit waist length 30L. Needless to say, the packaging bag 1 of this form can also be applied to pants-type disposable diapers 100 other than S size, for example, pants-type disposable diapers 100 of M size, L size, and other sizes.

In addition, when the ratio of the length from one edge to the other edge in the vertical direction and the length from one edge to the other edge in the width direction is 5:8, the length ratio of each length and width in the front surface 3 is the golden ratio. It approximates and is excellent in the aesthetics of the packaging bag 1, and is suitable.

(character display)
In order for a person who acquires (purchases) the packaging bag 1 to easily acquire the absorbent article 110 having a size that matches the body shape of the wearer, the size of the absorbent article 110 to be worn by the wearer is adjusted to the outer circumference of the packaging bag 1 . An information display portion 42 displaying information that can be confirmed by the length is preferably provided on the outer surface of the packaging bag. For example, characters, symbols, illustrations, or the like may be displayed on the packaging bag 1 . "The absorbent article has the longest perimeter length of the three perimeter lengths that is longer than the remaining two perimeter lengths, and the absorbent article has either one of the remaining two perimeter lengths. It is indicated on the packaging bag 1 that it is worn by a wearer whose waist length is within the range from the length to the longest outer circumference. This product is the optimal size for those who are within the range of the length and the longest outer circumference." However, if the text has the same meaning, the text can be changed as appropriate. By displaying in this way, the wearer whose waist length (or waist length) is from the lower limit waist length (or lower limit waist length) to the upper limit waist length (or upper limit waist length), It is easy to acquire the same packaging bag 1, and it is suitable. For example, when the S size pants-type disposable diaper 100 is designed to accommodate a wearer with a minimum waist length of 30L (lower limit of 50 cm) to an upper limit of waist length of 30L' (upper limit of 70 cm), the lower limit waist length A wearer having a body shape ranging from La (lower limit of 50 cm) to the upper limit of waist length 30L' (upper limit of 70 cm) should acquire the absorbent article 110 of S size. Similarly, if the M size pants-type disposable diaper 100 is designed to accommodate a wearer from another lower limit waist length (lower limit of 60 cm) to another upper limit waist length (upper limit of 85 cm), another lower limit A wearer having a body shape ranging from a waist length (lower limit of 60 cm) to another upper limit of waist length (upper limit of 85 cm) should obtain the pants-type disposable diaper 100 of M size. The same applies to L size, LL size, and sizes smaller or larger than these.

At least one of characters, symbols, illustrations, and the like can be displayed. The position to be displayed can be determined as appropriate, and can be displayed on at least one of the six sides of the packaging bag 1 . The area to be displayed is, for example, 10% to 90%, more preferably 20% to 80%, and even more preferably 30% to 70% of the area of the surface to be displayed. Visible and preferable. Also, the display position can be, for example, the left side, right side, upper side, lower side, or center of the surface to be displayed. Furthermore, the display position may be the upper end portion 7 or the handbag loop 41 .

Moreover, the illustration illustrated in FIG. 13 can be displayed on the packaging bag 1 .

(POP advertisements, etc.)
It is preferable that the advertisement medium 43 is provided with an information display section 42 displaying information that the size of the absorbent article to be worn by the wearer can be confirmed by the outer circumference length of the packaging bag. Advertisement media can use known means as appropriate, and for example, characters, symbols, and illustrations may be displayed in advertisements for sales promotion that are attached to products on product shelves, such as POP advertisements (Point of Purchase). However, it may also be displayed in flyers, Internet homepages, commercials (TV or Internet distribution videos).

(Embodiment of pants-type disposable diaper)
FIG. 10 shows a pants-type disposable diaper 100. FIG. This pants-type disposable diaper (hereinafter also simply referred to as a diaper) has an exterior body 20 forming a front body Fr and a back body Ba, and an interior body 10 fixed and integrated to the inner surface of the exterior body 20. The inner body 10 has an absorbent body 13 interposed between a liquid-permeable front sheet and a liquid-impermeable back sheet. In manufacturing, after the back surface of the inner body 10 is joined to the inner surface (upper surface) of the outer body 20 by a joining means such as a hot-melt adhesive, the inner body 10 and the outer body 20 are joined to the front body Fr and the back body Ba. is folded at the center in the depth direction (longitudinal direction) which is the boundary of the waist opening and a pair of left and right A pants-type disposable diaper having leg openings is obtained.

(Example of internal body structure)
The inner body 10 has a structure in which an absorber is interposed between a liquid-permeable top sheet made of nonwoven fabric or the like and a liquid-impermeable back side sheet made of polyethylene or the like. It absorbs and retains excreted fluid. Although the planar shape of the interior body 10 is not particularly limited, it is generally rectangular as shown in the figure.

As the liquid-permeable surface sheet covering the surface side (skin-contacting surface side) of the absorbent body 13, a perforated or non-perforated nonwoven fabric, a porous plastic sheet, or the like is preferably used. The material fibers that make up the non-woven fabric can be synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, and polyamides, as well as recycled fibers such as rayon and cupra, and natural fibers such as cotton. , spunbond method, thermal bond method, meltblown method, needle punch method, etc. can be used. Among these processing methods, the spunlace method is superior in flexibility and drapeability, and the thermal bond method is superior in that it is bulky and soft. When a large number of through-holes are formed in the liquid-permeable surface sheet, urine and the like are rapidly absorbed, resulting in excellent dry touch. The liquid-permeable topsheet may wrap around the side edges of the absorbent body 13 and extend to the back side of the absorbent body 13 .

The liquid-impermeable back sheet covering the back side (non-skin contact side) of the absorbent body 13 is made of a liquid-impermeable plastic sheet such as polyethylene or polypropylene. is preferably used. This water-impermeable/moisture-permeable sheet is a microporous sheet obtained by, for example, forming a sheet by melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene, and then stretching the sheet in a uniaxial or biaxial direction. be.

The absorber 13 is a known one, for example, a pile of pulp fibers, an aggregate of filaments such as cellulose acetate, or a non-woven fabric, which is optionally mixed or fixed with a superabsorbent polymer. can be used. The absorbent body 13 can be wrapped with a liquid-permeable and liquid-retaining wrapping sheet, such as crepe paper, if necessary, in order to retain the shape and the polymer.
The shape of the absorbent body 13 can be any arbitrary shape such as a substantially hourglass shape, a rectangular shape, etc. having a constricted portion narrower than the front and rear sides in the crotch portion.

Three-dimensional gathers BS are formed on both sides of the inner body 10 to fit around the legs. The three-dimensional gathers BS are composed of a fixed portion fixed to the side portion of the back surface of the inner body, a body portion extending from the fixed portion to the side portion of the surface of the inner body through the side of the inner body, and A fallen portion formed by fixing the front and rear end portions to the side portions of the surface of the inner body in a fallen state and a free portion formed by unfixing the portion between the fallen portions are folded to form a double sheet. It is made of gathered nonwoven fabric.

Also, between the double sheets, an elongated gathering elastic member is arranged at the tip of the free portion or the like. The gather elastic member is for forming a three-dimensional gather BS by erecting a free portion by elastic expansion and contraction force, as indicated by a chain double-dashed line in the product state.

The liquid-impermeable backside sheet may be folded back on both sides in the width direction of the absorbent body 13 together with the liquid-permeable topsheet. As the liquid-impermeable back side sheet, it is desirable to use an opaque one so that the brown color of excrement and urine does not appear. For opacification, a film obtained by internally adding a pigment or filler such as calcium carbonate, titanium oxide, zinc oxide, white carbon, clay, talc, or barium sulfate to a plastic is preferably used.

Materials such as styrene-based rubber, olefin-based rubber, urethane-based rubber, ester-based rubber, polyurethane, polyethylene, polystyrene, styrene-butadiene, silicone, and polyester can be used as the gather elastic member. Also, in order to make it difficult to see from the outside, it is preferable to set the thickness to 925 dtex or less, the tension to 150 to 350%, and the interval to 7.0 mm or less. As the gathered elastic member, a tape-like member having a certain width can be used in addition to the filament-like one shown in the figure.

As with the liquid-permeable surface sheet, the material fibers that make up the above-mentioned gathered nonwoven fabric are synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, and amides, recycled fibers such as rayon and cupra, and cotton. Natural fibers can be used, and nonwoven fabrics obtained by appropriate processing methods such as spunbonding, thermal bonding, meltblowing, and needle punching can be used. It is preferable to use a nonwoven fabric that suppresses the air permeability and is excellent in breathability. Furthermore, for the gathered nonwoven fabric 15, in order to prevent permeation of urine and the like, to prevent rashes, and to improve the feel (dry feeling) on the skin, a silicon-based, paraffin metal-based, alkylchromic cloid-based water repellent agent, etc., is added. It is desirable to use a water-repellent nonwoven fabric coated with

(Structure example of exterior body)
The outer body 20 has an elastic member disposed between the first sheet layer and the second sheet layer, and is imparted with elasticity in the width direction. The planar shape of the exterior body 20 has a pseudo hourglass shape as a whole due to concave leg circumference lines 29 formed to form leg openings on both sides of the middle. The exterior body 20 may be divided into front and rear parts, and the two parts may be arranged so as to be separated from each other in the depth direction at the crotch part.

More specifically, in the illustrated outer body 20, the waist region 2 is defined as the vertical range of the side seal portion 26 where the front body Fr and the back body Ba are joined.
3 is made larger than the elastic stress of the waist region TX. As a result, it is possible to apply a stretching force that appropriately tightens the waist portion.

The waist region is formed by folding back the extending portion of the armor 20 having the elastic member described above to the inner surface side.

The constituent materials of the first sheet layer and the second sheet layer can be used without any particular limitation as long as they are in the form of sheets, but non-woven fabrics are preferably used from the viewpoint of air permeability and flexibility. The nonwoven fabric is not particularly limited as to what the raw material fibers are. For example, synthetic fibers such as olefins such as polyethylene and polypropylene, polyesters, and polyamides, regenerated fibers such as rayon and cupra, natural fibers such as cotton, and mixed fibers and composite fibers using two or more of these. etc. can be exemplified. Furthermore, the nonwoven fabric may be manufactured by any processing. Examples of processing methods include known methods such as spunlace, spunbond, thermal bond, meltblown, needle punch, air through, and point bond methods. When a non-woven fabric is used, it is preferable that its basis weight is about 10 to 25 g/m ² . Also, the first sheet layer and the second sheet layer may be a pair of layers partially or wholly formed by folding one sheet of material and facing each other.

In this embodiment, a laminated elastic structure 20X made of elastic sheets is formed in the waist region T of the front body Fr, the waist region T of the back body Ba, and the intermediate region L therebetween in the outer body 20. be able to.
An elastic member is laminated between the first sheet layer and the second sheet layer, and the first sheet layer and the second sheet layer are stretched in the stretching direction while the elastic member is stretched in the width direction. It is joined by a large number of joining portions 40 arranged at intervals in the (width direction) and the direction (depth direction) orthogonal thereto.

In such a laminated stretchable structure 20X, basically, the higher the area ratio of the joint 40, the smaller the portions of the first sheet layer and the second sheet layer that are shrunk by the elastic film, so the elastic limit elongation tends to decrease. There is

(Front and rear holding sheet)
Front and rear pressing sheets 50 and 60 may be provided to cover the front and rear ends of the interior body 10 attached to the inner surface of the exterior body 20 and to prevent leakage from the front and rear edges of the interior body 10 . More specifically, the front pressing sheet 50 extends across the entire width direction from the inner surface of the folded portion 20C at the waist-side end portion of the inner surface of the front body Fr to a position overlapping the front end portion of the inner body 10. , the rear pressing sheet 60 extends across the entire width direction from the inner surface of the folded portion 20C at the waist-side end portion of the inner surface of the back body Ba to a position overlapping the rear end portion of the inner body 10 . If a slight non-adhesive portion is provided on the crotch side edge of the front and rear pressing sheets 50 and 60 over the entire width direction (only the central portion is also acceptable), not only does the adhesive not protrude, but this portion is slightly removed from the top sheet. It can be made to float and function as a leak-proof wall.

Attaching the front and rear pressing sheets 50 and 60 separately as in the illustrated embodiment has the advantage of increasing the degree of freedom in material selection, but also has the disadvantage of increasing the number of materials and manufacturing processes. Therefore, a folded portion 20C formed by folding the outer body 20 to the inner surface of the diaper may be extended to a portion overlapping the inner body 10 to form a portion equivalent to the pressing sheets 50 and 60 described above.

(girth length)
As shown in the embodiment of FIG. 10, the waist length 30L of the pants-type disposable diaper 100 in the unfolded state is the sum of the abdominal side width direction length W1 and the back side width direction length W2 in the waist length region T. expressed. However, since the lengths W1 and W2 are expanded and contracted by the elastic member provided in the region T, it is possible for a wearer within a predetermined waist length range to wear the pants-type disposable diaper 110 .

When the wearer wears this underpants-type disposable diaper 100, it assumes a three-dimensional structure as shown in FIG.

(Embodiment of tape-type disposable diaper)
FIG. 11 shows the outline of a tape-type disposable diaper 110a. The tape-type disposable diaper 110a extends in the dorsal-abdominal direction LD and the width direction WD. A ventral portion F having a width of W4 and a dorsal portion B having a width of W3 extend from the central portion Z to the edge side in the dorsal-ventral direction LD. Connection tapes 13, 13 are provided outside in the width direction WD from both width direction edges of the back portion B. Further, the tape-type disposable diaper 110a can adopt an appropriate shape such as a square shape, a trapezoid shape, or a so-called hourglass shape in which the central portion Z in the dorsal-abdominal direction LD is narrower than the edge side.

(connecting tape)
Connecting tapes 13 that are detachably connected to the outer surface of the ventral portion F are provided at both edges in the width direction of the dorsal portion B, respectively. When wearing the diaper 100a, the connecting tapes 13 are wrapped around the outer surface of the abdominal portion F from both sides of the waist, and the connecting tapes 13 are connected to the outer surface of the abdominal portion F at appropriate locations.

The structure of the connecting tape 13 is not particularly limited, but includes a tape mounting portion 13C fixed to both edges in the width direction of the back portion B, a sheet base material forming a tape body portion 13B projecting from the tape mounting portion 13C, and this A connecting portion 13A for the ventral side is provided in the widthwise intermediate portion of the tape main body portion 13B of the sheet base material, and the leading end side of the connecting portion 13A serves as a knob portion.

As the connection portion 13A, a hook member (male member) of a mechanical fastener (surface fastener) may be provided, or an adhesive layer may be provided. The hook material has a large number of engaging projections on its connection surface, and the shapes of the engaging projections are (A) square-shaped, (B) J-shaped, (C) mushroom-shaped, and (D).

When the wearer wears this tape-type disposable diaper 100a, it has a three-dimensional structure as shown in FIG.

(others)
A consumer who acquires (purchases) an absorbent article may be the wearer himself or a caregiver. When caring for a wearer (care recipient), for example, when a sitting care recipient stands up, the caregiver wraps both arms around the care recipient's waist and grasps the other arm with one hand. The person being cared for may be made to stand while being held in a circle. Based on this experience, the caregiver can intuitively measure the approximate girth length of the care recipient by forming a loop with both arms. Even if the wearer is not at the store, the caregiver can obtain an absorbent article of suitable size by wrapping both arms around the packaging bag 1 to form a loop.

According to the present invention, the outer peripheral length of the packaging bag 1 differs depending on the size of the waist length or the waist length, for example, S size or M size. For example, in the case of S-size underpants-type disposable diapers, about 5 to 7 diapers are accommodated in the packaging bag 1, and the outer peripheral length of the packaging bag is 50 cm and 70 cm.

INDUSTRIAL APPLICATION This invention is utilized for the packaging bag of absorbent articles, such as an underpants type disposable diaper and a tape type disposable diaper.
