Description

DETAILED DESCRIPTION OF THE INVENTION

FIELD OF THE INVENTION The present invention relates to sanitary napkins, panty liners, and absorbent articles such as adult incontinence pads. More particularly, the present invention relates to an individual wrapper for an absorber of the type described above, which is folded or wrapped around the underwear side of the wearer. An absorber having an element.

BACKGROUND OF THE INVENTION Absorbents such as sanitary napkins, panty liners, and incontinence pads are devices that are typically worn on the crotch of underwear. These devices are designed to absorb and retain liquids and other excretions from the human body and to prevent soiling of the body and clothing. Sanitary napkins are a type of absorber that women wear on panties, usually located between the wearer's legs and adjacent the perineum of the body.

[0003] There are numerous variations of the specific structural members of the absorber, which are often provided to consumers in the same way. Essentially, the absorbent is packaged in a box or bag, regardless of the particular structural components used, from which the consumer removes the ready-to-use product as needed. Generally, the absorber includes a fastener, for example, a pressure-sensitive adhesive fastener, for fastening the absorber to the wearer's underwear on the side of the absorber facing the clothing. The adhesive fastener must be provided with a releasable covering strip to prevent the adhesive from sticking to surfaces other than the wearer's underwear before use.

[0004] Furthermore, if a consumer needs only one product for subsequent use,
Consumers are advised from the time they are taken out of the box or bag until the product is used.
Care must be taken to prevent this product from becoming dirty or contaminated. This is a special problem with menstrual pads. For example, if a woman wants to carry a menstrual pad for use away from home, care must be taken to ensure that the pad is not damaged or soiled when carried in a bag or pocket. Will not be.

[0005] The protection of individual absorbers has been addressed in the prior art. For example, bandages are typically packaged individually and sold to consumers in certain containers containing a convenient number of individually packaged products. Menstrual pads are similarly individually packaged and sold to consumers in containers containing a convenient number of individually packaged products. U.S. Pat. No. 2,750,033 issued to JB Pickens on June 12, 1956 and entitled "Napkin Packaging"; and August 1976. On March 10th, SS Srinivasan and others (SS Sri

Although these wrappers protect the enclosed sanitary napkin, they require a sufficient amount of wrapper material to cover the entire surface area of both sides of the sanitary napkin.

[0006] Other attempts at protecting individual absorbers have reduced the amount of wrapper material required to protect each absorber. In particular, issued December 3, 1985 to Swanson et al., "Individually Packed Disposable Disposable Absorbers".

[0008] The packaging described above is not ideal for use with absorbent articles such as composite sanitary napkins. Because, when such a product is folded into three, the folding of the bulky first absorbent component triples the thickness of the absorber along the longitudinal centerline, while The thickness of the folded longitudinal side edges of the product is only slightly increased. These publications also do not disclose arrangements for packaging absorbent articles having flaps or other side wrapping elements.

Accordingly, it is an object of the present invention to provide a peelable cover arrangement for an absorbent article, such as a composite sanitary napkin, having a portion with a large bulk.

[0010] Another object of the present invention is to provide an individual package for such an absorber.

Yet another object of the present invention is to provide a compact package that maintains the bulk of such an absorbent body when unpacked without unduly compressing.

Yet another object of the present invention is to avoid the formation of wrinkles or fold lines in the absorbent during packaging.

[0013] These and other objects of the present invention will become more readily apparent when considered with reference to the following description and when taken in conjunction with the accompanying drawings.

SUMMARY OF THE INVENTION The present invention is directed to individual packages for absorbent articles, such as sanitary napkins, panty liners, and adult incontinence pads.

[0015] The individually packaged absorber comprises an absorber and a wrapper. The absorber has a body facing side, a garment facing side, and an adhesive fastener on the garment facing side. The absorber preferably comprises a first absorbent component forming at least a portion of the absorber on the body-facing side. The first absorbent component has a longitudinal axis, a width, and a pair of longitudinal side edges. The first absorbent component is joined to the base pad. In one preferred embodiment, the base pad is wider than the first absorbent component so that the base pad laterally extends beyond each of the longitudinal side edges of the first absorbent component. Having a portion extending outwardly. These parts form extensions of the base pad.

A wrapper for packaging the absorbent body has a flexible sheet. An extension of the base pad is wrapped around the first absorbent component relative to a longitudinal axis of the first absorbent component. The extension of the base pad may be wrapped in the same direction about the longitudinal axis of the first absorbent component. Alternatively, they can be wound in opposite directions around the first absorbent component. When the extension of the base pad is wrapped around the first absorbent component, the wrapper forms a package for the absorbent, preferably a tubular package.

DETAILED DESCRIPTION OF THE INVENTION General Features The present invention is directed to individual packages for absorbent articles such as sanitary napkins, panty liners, interlabial devices, and adult incontinence pads. This individual package is preferably used to package an absorbent body having at least one relatively large caliper portion and another relatively small bulk portion. In one preferred embodiment, the wrapper forming the individual wrap for the absorber comprises a flexible sheet used to form a tubular wrap for the absorber.

FIGS. 1-3 show one preferred embodiment of a sanitary napkin 20 that can be packaged in the individual package of the present invention. As shown in Figures 1-3, this sanitary napkin is in the form of a composite sanitary napkin. As shown in FIG. 1, the sanitary napkin 20 basically comprises a body portion 22 and two side extensions or side wrapping elements 24. The main body portion 22 of the sanitary napkin 20 includes:
The first absorbent member (or “first absorbent component” or “core tube”) 40 and the second absorbent member (or “second absorbent component”) joined to each other by the combining means 70.

The first absorptive member 40 arrange | positioned at is provided. The sanitary napkin 20 shown in FIG. 1 may be of any suitable size. Preferably, the embodiment of the sanitary napkin 20 shown in the figures is relatively large in size so that it can cover the largest area of the wearer's panties, especially for night use. The panties can be reduced or eliminated from being soiled by fluid from the wearer's body. It should be understood that the sanitary napkin shown is only one preferred embodiment and that the present invention is not limited to use with an absorbent of this type or having the particular shape shown in the drawings. It is.

2. FIG. 2 shows the individual components of the body portion 22 of the sanitary napkin 20.
The body portion 22 of the composite sanitary napkin shown in the drawing basically includes the first absorbent member 40 and the second absorbent member 60 as described above.

A. First absorbent member 1. General Features The first absorbent member (or "first absorbent component") 40 is a composite sanitary napkin 20 for absorbing fluid from a bulk body excreted by a user.
Part. The first absorbent member 40 has a side edge 44 and an edge 46, which together form a periphery 48 of the first absorbent member 40. The first absorbent member 40 includes:
It has an absorbent structure, for example, an absorbent core 50 and an outer covering 52 stacked on the absorbent core 50. (As used herein, the term "stacked (su
"Perimposed" means adjacent or juxtaposed, but does not necessarily mean contacting or joining. 2) As shown in FIG. 2, the first absorbent member 40 has a longitudinal axis, a vertical center line V,
It has a base B and a peak A which is on the opposite side perpendicular to the base B. As used herein, the term "foundation" refers to a portion of the first absorbent member 40 that is juxtaposed with the body-facing surface 60A of the second absorbent member 60.

[0024] The first absorbent member 40 may be provided in a variety of suitable shapes. The shape of the first absorbent member 40 is often determined by the shape of the absorbent core 50 (described below). Suitable shapes for the first absorbent member 40 are cylindrical,
They are rectangular, oval, and trapezoidal. In the preferred embodiment shown in the figures, the first absorbent member 40 is generally cylindrical and has an oval cross section.

The first absorbent member 40 is preferably approximately centered along the longitudinal centerline L and the transverse centerline T of the sanitary napkin 20. Basic B of the first absorbent member 40
At least a portion is preferably joined or in face-to-face contact with body-facing surface 60A of second absorbent member 60. (As used herein, the term "joined" refers to a form in which one element is directly fixed to another element by attaching the element to another element; itself is another element. A configuration in which the element is indirectly fixed to another element by attaching the element to one or more intermediate members attached to the other element; and one element is integral with the other element, ie, 1 Includes configurations where one element is essentially a part of another.) The first absorbent member 40 may be of any suitable size. In the preferred embodiment shown, the first absorbent member 40 and the second absorbent member 60
Are the same length. However, it is entirely possible that the first absorbent member 40 still functions effectively even though it is shorter than the second absorbent member 60. Accordingly, the length of the first absorbent member 40 may vary up to the lengths described herein for the second absorbent member 60. In embodiments of normal size, for example, those intended for daytime use, the first absorbent member 4
0 is preferably about 2 to 35 cm in length, more preferably about 10 to 35 cm in length, and most preferably about 20 to 35 cm in length. A particularly preferred first absorbent member 40 for use in such daytime embodiments has a length of about 17 to 20 cm. The first absorbent member 40 is preferably about 0.5 to 5 cm wide in its base B, more preferably about 0.5 to 4 cm wide, and most preferably about 0.5 to 3 cm wide. Up to the width.

[0026] 2. Outer Cover Outer cover 52 comprises one component that is at least partially liquid permeable so that liquid can easily penetrate through its thickness. When the sanitary napkin 20 is being used, the outer cover 52 is very close to the user's skin. The outer cover 52 is preferably as soft and soft as possible and non-irritating to the user's skin. The outer cover 52 should also exhibit good bleed-through and low tendency to re-wet so that bodily exudates can penetrate quickly and the core 50
, But it is better to prevent such excrement from flowing back to the wearer's skin through the outer cover 52.

Suitable outer covers 52 include a wide range of materials, such as woven and non-woven materials; polymeric materials, such as apertured thermoplastic films, apertured plastic films, and hydraulically molded thermoplastic films; porous foams; Reticulated foams; reticulated thermoplastic films; and thermoplastic scrims. Suitable woven and nonwoven materials include natural fibers (eg, wood fibers or cotton fibers), synthetic fibers (eg,
For example, it may be composed of polymer fibers such as polyester, polypropylene or polyethylene fibers); or it may be composed of a combination of natural and synthetic fibers. Outer cover 52 may be a unitary member or may be comprised of two or more elements joined together to form outer cover 52. Furthermore, any portion of the material with the outer cover 52 may be coated, laminated, treated, or also have any desired characteristics of the outer cover, such as strength,
It may be manipulated to provide or enhance flexibility or liquid permeability.

A preferred outer cover 52 includes an apertured film. Open-molded films are preferred for the outer cover 52 because they are permeable to bodily exudates and, if properly opened, the liquid flows back through the film and is mounted. This is because the tendency of the individual to re-wet the skin will be reduced. Thus, the surface of the molded film in contact with the body remains dry, which reduces the soiling of the body and creates a more comfortable feel for the wearer. Furthermore, if desired, molded films can be readily manufactured with non-opening portions or portions that provide a liquid impermeable area that prevents any liquid from passing through. Suitable molded films are disclosed in U.S. Pat. No. 3,929,135 issued to Thompson on December 30, 1975; and Mullane et al. On April 13, 1982. U.S. Pat. No. 4,324 issued
Radel et al., Aug. 3, 1982; Radel, et al.
U.S. Patent No. 4,342,314 issued to Ahr, et al. On July 31, 1984.
And U.S. Patent No. 5,006,394 issued to Baird on April 9, 1991. One particularly preferred outer cover 52 for the first absorbent member 40 is described in one or more of the aforementioned patents, and The Procter & Gamble, Inc. of Cincinnati, Ohio. Gamble Com
pany) as a “DRI-WEAVE” topsheet on a sanitary napkin.

In a preferred embodiment, the body-facing surface of at least a portion of the outer cover 52 makes excrement easier to remove than if the body-facing surface is not hydrophilic.
It is made hydrophilic to help move through it. This reduces the likelihood of body exudates flowing into the absorbent core 50 and falling off the outer cover 52 without being absorbed therein. The body side surface of the outer cover 52 may be made hydrophilic by treating it with a surfactant. In a preferred embodiment,
The surfactant is incorporated into the polymeric material of the formed film as described in U.S. Pat. No. 4,950,264 issued Aug. 21, 1990 to Osborn.

The first absorbent member 40 may include a wrap for the absorbent core 50, such as the receiving layer 58 shown in FIG. The receiving layer 58 includes the outer cover 52.
And another component located between the absorbent core 50 and this may be an integral part of the composite outer cover. The receiving layer 58 can serve several functions, including improved wicking of excreta on and into the absorbent core 50 and / or an absorbent material on the absorbent core 50. Is to be included. Due to the improved excretion wicking, the receiving layer 58 provides a more uniform distribution of excrement throughout the absorbent core 50. The receiving layer 58 may be composed of various materials. These materials include synthetic fibers, including polyester, polypropylene, or polyethylene; natural fibers, including cotton or cellulose; blends of these fibers; or nonwoven or woven webs of any equivalent material or combination of materials, and tissue ( tissue). An example of a sanitary napkin having a receiving layer is described in U.S. Pat. No. 4,9,967 issued to Osborn.

In a preferred embodiment, receiving layer 58 may be joined to outer cover 52. These components may be joined by any of the usual means for joining webs together, including by an adhesive, a spray adhesive (spra).
a plurality of discrete individual fusions by wrapping the outer cover 52 around the receiving layer 58 by applying a line or spot of adhesive between the outer cover 52 and the receiving layer 58 by y-gluing. Bonding Outer Cover 52 to Receiving Layer 58 by Fusing Cover 52 to Receiving Layer 58 or by Bonding Outer Layer 52 to Receiving Layer 58 by Any Other Means Known in the Art , But is not limited to these.

Referring now to FIG. 2, it can be seen that the outer cover 52 completely encloses the absorbent core 50 of the first absorbent member 40. In other embodiments, outer cover 52 need not completely surround absorbent core 50. In such an embodiment, outer cover 52 may substantially surround absorbent core 50. (As used herein, the term “substantially encircling”
"circle)" means that the outer cover covers more than half of the absorbent core, more preferably the majority of the absorbent core. ) Outer cover 5
In embodiments where the 2 does not completely surround the absorbent core 50, a passage or liquid passage may be formed between the first absorbent member 40 and the second member 60.
This passage may provide a passage to the second member 60 such that any liquid not retained by the first absorbent member 40 is absorbed and contained therein.

[0032] 3. Absorbent Nucleus The absorbent nucleus (or absorbent component) 50 used in the sanitary napkin 20 shown in the figures receives, absorbs, and contains body excrement. The absorbent core 50 also preferably maintains the shape of the first absorbent member 40, so that the first absorbent member 40 conforms to the shape of the wearer's body. Thus, the absorbent core 50 is preferably capable of absorbing and containing bodily exudates, is compressible, conforms easily, is elastic, and does not irritate the wearer's skin.

The total absorption capacity of the absorbent core 50 should be compatible with the intended excrement load on the first absorbent member 40. The first absorbent member 40 is preferably
A capacity equal to at least the lower end of the capacity range of the sanitary napkin described in U.S. Pat. Nos. 4,950,264 and 5,009,653 issued to Osborn. Preferably, it has a greater capacity. For example, the first absorptive member 40 is a male bone (Osbor).
n) about 20-60 sterile salt solutions measured according to the procedure disclosed in US Pat. No. 5,009,653 issued to
Has a total capacity between grams. Furthermore, the absorption capacity of the absorbent core 50 may vary for wearers within the expected volume of excrement liquid volume.
For example, for sanitary napkins for day use compared to those for night use, or sanitary napkins for use by teen women compared to use by more mature women , Various absorption capacities can be used.

The material selected for use as the absorbent core 50 is preferably flexible, soft, comfortable and compressible to improve the body fit and comfort of the first absorbent member 40. And elastic. Preferably, the absorbent core 50 is compressible so that the first absorbent member 40 deforms under the relatively small force exerted by the external genitalia during normal use. In addition to being compressible, the absorbent core 50
The material with is preferably conformable, so that the first absorbent member 40 can provide an improved fit in and around the wearer's labia and perineum. Similarly, it is also important that the first absorbent member 40 be sufficiently elastic so that it does not permanently collapse when subjected to normal mounting forces. The absorbent core 50 provides the first absorbent member 40 with the desired elastic characteristics, such that the first absorbent member 40 is contoured to the body so as to create intimate contact with the exposed genitals of a female user. Fit. Due to intimate contact with the exposed female genitalia, such liquids do not bypass and / or run down the first absorbent member 40, and the liquid waste from the user to the first absorbent member 40 is better. Movement occurs. The resilient features of the absorbent core 50 allow for improved fit, but these must be balanced against the need for this product to be both soft and comfortable for the wearer. No.

The absorbent core 50 may comprise any material capable of absorbing or retaining liquids (eg, menstrual secretions and / or urine). The absorbent core 50 may also be made from a wide variety of liquid absorbent materials commonly used in sanitary napkins and other absorbents, for example, finely divided wood pulp, commonly referred to as airfelt.

The shape and configuration of the absorbent core may also vary (i.e., the absorbent core may have different bulk areas (e.g., profiled such that the center is thicker),
May have a hydrophilic gradient, a superabsorbent gradient, or a receiving compartment of relatively low average density and relatively low average basis weight; or may comprise one or more layers or structures) . However, it is to be understood that for the purposes of the individual packaging described herein, the material making up the absorbent core is not critical.

In the embodiment shown in the figures, the absorbent core 50 comprises an absorbent core material. The absorbent foam material used for the absorbent core 50 was found on October 13, 1995 by John C. Dyer and others (John CD).

B. Second Absorbent Member The second major component of the embodiment of the composite sanitary napkin shown in FIGS. 1-3 is a second absorbent member 60. The second absorbent member 60 is primarily intended to prevent the user's clothing from being soiled by absorbed liquid that may be expelled from the first absorbent member 40 or accidentally bypass the first absorbent member 40. Fulfill. Accordingly, the second absorbent member 60 generally performs a function different from that of the first absorbent member 40, and is preferably somewhat thinner and less bulky than the first absorbent member 40.

The second absorbent member 60 may be of any suitable plan view shape and size. For example, top view shapes of the second absorbent member 60 include generally rectangular, oval, hourglass, dog bone, asymmetric, and other shapes known in the art, including: It is not limited. In the embodiment shown in FIGS. 1-3, the second absorbent member 60 is preferably generally hourglass shaped. The width of the second absorbent member 60 is at least 1.5 times the width of the first absorbent member 40. More preferably, the width of the second absorbent member 60 is at least twice the width of the first absorbent member 40. Most preferably, the width of the second absorbent member 60 ranges from about 3 to about 8 times the width of the first absorbent member 40. Since the base pad 60 is wider than the first absorbent element 40, the base pad 60
It has a portion extending laterally outward from each of the zero longitudinal side edges 44 to form an extension 38 of the base pad 60. The side wrapping element 24 preferably extends laterally outward from the longitudinal side edge of the extension of the base pad 60.

The second absorbent member 60 may be of various thicknesses. In the embodiment shown, the second absorbent member 60 is preferably very thin and flexible or "ultra-thin". The second absorbent member 60 is preferably about 3.0 mm
Less than about 2.6 mm, even more preferably less than about 2.2 mm, and most preferably less than about 2.0 mm. An example of a sanitary napkin that can be used as the second absorbent member 60 is Osborn.
U.S. Patent Nos. 4,950,254 and 5,009,653 issued to
It is described in the issue.

However, the second absorbent member 60 in another embodiment may have a sufficiently smaller absorption capacity than the first absorbent member 40. For example, the second absorbent member 60 may have a total absorbent capacity of between about 5 and 15 grams of body waste. Preferably, the ratio of the total capacity of the first absorbent member 40 / the total capacity of the second absorbent member 60 is between about 1: 1 and about 10: 1, and more preferably about 5: 1.

The second absorbent member 60 preferably has at least two components.
These include an absorbent element 62 and a liquid impermeable backsheet 66 joined to the absorbent element 62. The absorbent element 62 may form a surface 60A that contacts the body of the second absorbent member 60. In another preferred embodiment, the second absorbent member 60 may comprise a liquid-impermeable backsheet 66, a liquid-permeable topsheet 64 joined to the backsheet 66, wherein the absorbent element 62 comprises , Between the top sheet 64 and the back sheet 66. In still another embodiment, the second absorbent member 60 includes, in addition to the top sheet 64,
Alternatively, a receiving layer 68 may be provided. These components of the second absorbent member 60 will now be examined in more detail.

The topsheet 64 may be any liquid permeable material commonly used for sanitary napkins, disposable diapers, and the like. The topsheet 64 may be any of the materials described above for use with the outer cover 52 of the first absorbent member 40, including but not limited to nonwovens and apertured films. Do not mean.

The receiving layer 68 of the second absorbent member 60 may comprise any of the materials described above for the receiving layer 58 of the first absorbent member 40. In a preferred embodiment, the second absorbent member 60 includes a receiving layer 68 disposed between the topsheet 64 and the absorbent element 62. However, embodiments are also contemplated in which the receiving layer 68 replaces the topsheet 64, the absorbent element 62, or both. In such embodiments, the receiving layer 68 provides the second absorbent member 60 with the desired absorption properties.

The absorbent element 62 can be manufactured from a variety of liquid absorbent materials commonly used in disposable sanitary napkins and other disposable absorbent articles.

Paper tissue made by the process described in U.S. Pat. No. 3,994,771, issued to Morgan, et al. On November 30, 1976, is also an absorbent element 62. Can be used advantageously.
Wet strength resins and latex binders can be used to provide additional strength to the paper tissue used for the absorbent element 62.

The backsheet 66 of the second absorbent member 60 is preferably impermeable to liquids (eg, menstrual discharge and / or urine) and is preferably made from a thin plastic film. However, other flexible liquid impermeable materials can also be used. As used herein, the term "flexible" refers to a material that is flexible and that readily conforms to the general shape and contours of the human body. The backsheet 66 is inserted between the absorbent element 62 and the user's underwear during use. The function of the backsheet 66 is to allow excrement that may be expelled from or bypass the absorbent core 50 and that is absorbed and contained by the absorbent element 62 in contact with the user's undergarment. To prevent them from getting dirty.

The backsheet 66 may comprise a woven or nonwoven material, a polymer film, such as a thermoplastic film of polyethylene or polypropylene, or a composite material, such as a film-coated nonwoven material. Preferably, the backsheet has about 0.012

No. 842,666 with several lines of spirally wound adhesive filament illustrated by the apparatus and method shown in U.S. Pat. The core-integral adhesive may cover the entire garment-facing side of the second absorbent member, the entire width of the product (including the extension of the backsheet lying beyond the edge of the absorbent element 62), or any portion thereof. May be applied above. Preferably the core adhesive is
It applies to the entire interface between the garment side of the topsheet 64 and the backsheet 68.

In order to form the composite sanitary napkin shown in the figures, the first absorbent member 40 and the second absorbent member 60 are integrated as shown generally at 70 in FIGS. Join by means. The exact type of the integrating means is such that the first and second absorbent members 40 and 60 have sufficient toughness so that the selected integrating means does not fall apart during use. It is not critical as long as it serves to join the second absorbent member 60 to the composite sanitary napkin 20 shown in the figure. Integrated means such as gluing with known hot melt and pressure sensitive adhesives are quite satisfactory. If this is possible, depending on the type of elements selected to constitute the components of the composite sanitary napkin 20, use heat welding, ultrasonic welding, dynamic mechanical bonding, or a combination of any of the foregoing means. You may.

The sanitary napkin 20 shown in FIGS. 1-3 is preferably also a pair of side extensions () for folding around the side edges of the wearer's panties (or other underwear).
Or “side wrapping element”) 24. As shown in FIG. 1, the body portion 22 has a smaller width measured in the central region 36 than in its end regions 32 and 34. Side wrapping element 24 extends from at least central region 36 of body portion 22.

The side wrapping elements 24 each have a proximal edge 74 and a distal edge 76. Side wrapping elements 24 are joined to body portion 22 at their proximal edges 74. In the embodiment shown in the figures, the side wrapping element 24
The proximal edge 74 is preferably concave (relative to the distal edge 76). The distal edge 76 of the side wrapping element 24 is preferably substantially parallel to the longitudinal centerline L.

The side wrapping element 24 of the embodiment shown in FIGS. 1-3 is preferably integral with the body portion 22 of the sanitary napkin. In such a case, the topsheet 64 of the second absorbent member 60 may form part of the side wrapping element 24, and the backsheet 66 may form part of these. For example, the topsheet 64 may form the body-facing surface of both the side wrapping element 24 and the body portion 22, and the backsheet 66 may form the garment-facing surface thereof. In an alternative embodiment, side wrapping element 24 may be comprised of a separate piece of material or element attached to body portion 22. When the side wrapping elements 24 comprise separate elements, they may be joined to the body portion 22 by any technique known to those skilled in the art. Such techniques include, but are not limited to, adhesives, heat and / or pressure, ultrasound, and the like.

The side wrapping elements 24, whether integral with the body portion or separate components attached to them, each along the joint
Combined with 2. The joint is typically a longitudinally oriented (or “longitudinal”) joint, for example, a joint line 78. As used herein, the term "joint" (or "joint line") refers to a portion where the side wrapping element 24 extends from or is joined to the body portion 22. The joint 78 may be any of a variety of curves or straight lines, but these are not limited to lines. Thus, the joint may include regions, flanges, strips, interrupted lines, and the like. In the sanitary napkin 20 shown in FIG. 1, the joining line 78 is a generally longitudinally oriented region of a concave shape relative to the distal edge 76 of the side wrapping element. When the side wrapping element 24 is integral with the body portion 22, the joint line 78 may represent a boundary between the body portion 22 and the side wrapping element 24. However, there is no need for an accurate boundary line to exist.

As shown in FIG. 1, each side wrapping element 24 is divided into a front half 80 and a rear half 82 by a side wrapping element transverse centerline T 1. The side wrapping element transverse centerline T1 may coincide with the main transverse centerline T of the sanitary napkin, but this is not absolutely necessary. In other embodiments where the body portion 22 is not symmetrical along its length, the side wrapping elements 24 may be more located at one end of the body portion and thus the side wrapping element transverse centerline. T1 may be offset to either the front or back of the main transverse centerline T.

The side wrapping elements 24 include adjacent portions 86 of these side wrapping elements.
A weakened region 84 having higher flexibility is provided. These weakened areas 84
In each side wrapping element 24, at least one weakened region or at least a portion thereof is on either side of the side wrapping element transverse centerline T1,
It is located at least partially longitudinally away from the flap transverse centerline T1 in both directions. In the most preferred case, the weakened area 84 is located along a portion of the fold line, where the side wrapping element 24 is folded around the wearer's panty crotch. In this preferred case, the weakened region 84 may be located on or near the transverse centerline T1. The fold line is generally at a location along or adjacent the longitudinal joint 78 of each side wrapping element 24. As used herein, the terms "portion", "zone", and "region" refer to a general area, and thus the weakened region 84 is limited to points that are exactly on the joint line 78. Not necessarily. Generally, these include both points that lie on the juncture line 78 as well as the area around the sanitary napkin 20 that includes the fold line. Thus, the longitudinal joint is simply a weakened area 84.
May be used as an approximate part for the position of.

The weakened area 84 is preferably also extendable. Thus, the weakened region 84 may be considered to have different stretchable areas (or “stretchable areas”). As used herein, the term "different stretchable area" refers to a portion of the side wrapping element 24 that can extend a different amount (preferably a greater amount) than the adjacent portion 86 of the side wrapping element 24. To tell. The extensibility of the weakened area 84 mitigates the stresses that occur at the side wrapping element 24 when folded around the side of the wearer's panties crotch.

The weakened region 84 in the embodiment shown in FIG. 1 can extend in a direction between the longitudinal direction and the transverse direction. In other embodiments, the extensibility of the weakened region 84 may be fully transversely oriented, more transversely than longitudinally, and more longitudinally than transversely. It may be oriented or completely longitudinal. The side wrapping element 24 may include other optional weakened areas, such as those shown along the transverse centerline T in FIG.

The weakened area 84 may include any structure that is more flexible and potentially extendable than the adjacent area 86 of the side wrapping element 24. Suitable structures for the weakened region 84 are mechanically strained, corrugated, "ring rolled" (the term "ring rolled (rin
“g rolled” refers to the strain and / or activation resulting from feeding the material into intermeshing corrugated rolls), folded, Chapel, et al., May 21, 1996. Issued to "Web Materials Exhibiting El

No., 897, ring-rolled. Ring rolling (also known as “preliminary waveform formation”) forms a waveform in the weakened region 84. These corrugations have ridges and valleys defined by fold lines 88. Fold line 88 may form any desired angle with respect to main longitudinal centerline L. In the preferred embodiment shown in FIGS. 1-3, the fold line 88 forms an angle between the main longitudinal centerline L and about 40-80 °. This will produce the desired direction of extensibility.

The sanitary napkin 20 preferably also has a fastener suitable for securing the sanitary napkin 20 to the crotch of the undergarment. FIGS. 2 and 3 show one preferred type of fastener in the form of an adhesive attachment means, such as a center pad adhesive 94 and a side wrapping element adhesive 96. However, the fasteners used in the sanitary napkins shown in the figures are not limited to adhesive bonding means. All types of fasteners used in this technique can be used for such purposes. For example, the sanitary napkin 20 could be secured to the wearer's underwear by frictional fasteners, mechanical fasteners, or a combination of any of the foregoing types of fasteners. However, for simplicity, these fasteners will be described as adhesive attachment means, and they are preferably pressure sensitive adhesive fasteners. Suitable pressure sensitive adhesive fasteners are described in more detail in U.S. Pat. No. 4,917,697.

The adhesive fasteners 94 and 96 may be arranged in any suitable shape.
FIG. 3 shows one possible panty fastener pattern. The panty fastener pattern shown in FIG. 3 includes a pair of longitudinally oriented central pad fasteners 94 on opposite sides of the main longitudinal centerline L. The longitudinally oriented central pad fastener 94 shown in FIG. 3 preferably extends substantially the entire length of the absorbent element 62 of the second absorbent member 60. The longitudinally oriented central pad fasteners 94 preferably each have an inner edge 94A, which is generally straight. The inner edges 94A of the longitudinally oriented fasteners 94 are preferably spaced from one another and from the main longitudinal centerline L of the sanitary napkin 20. This moves the longitudinally oriented central region of the sanitary napkin 20 (without fasteners thereon) away from the wearer's panties so that it comes into close contact with the wearer's body. Can be moved. The longitudinally oriented central pad fastener 94 preferably has an outer edge 94B and an end 94C that are similar in shape to the outer edge of the absorbent element 62 of the second absorbent member 60.
This provides a central pad fastener 94, generally in the form of an hourglass, with a longitudinally oriented gap at the center. In addition to the longitudinally oriented central pad fastener 94, the sanitary napkin 20 preferably has two side wrapping element fasteners 96 on each side wrapping element 24, one of which is , Side wrapping elements on either side of the transverse centerline T. It should be understood that this is only one possible fastener shape and many other shapes are possible.

The adhesive attachment means, eg, the center pad adhesive 94 and the side wrapping element adhesive fastener 96, are each provided by a separate removable release liner to prevent the adhesive from sticking to the outer surface prior to use. May be covered. A suitable release liner that can be used for the side wrapping element fastener 96 is Osbor
