Description

ARTICLE OF STRIPS RESISTANT TO THE STAIN AND METHOD BACKGROUND OF THE INVENTION Field of the Invention This invention relates to a protective article against stains and to a method for protecting a user's garments from body fluids including menstrual fluids and / or other exudates from the body. More specifically, this invention relates to a protective article against stains and to a method for protecting the user of an undergarment from the lateral runoff of menstrual fluids around an absorbent pad for the care of women.

Background of the Invention Currently, many varieties of products are available for the absorption of fluids from the human body in the form of pads for women, sanitary napkins, shields for panties, linings for panties and incontinence devices. The absorbent products to provide protection for female care are designed to absorb body fluids, including menstrual fluids, and come in different functional designs. Sanitary towels and the women's care pads worn externally around the pudenda area are absorbent pads primarily designed for menstrual flow. Pant lining or panty shields are thin sanitary napkin products used around the pudenda area for light menstrual flow. Absorbent products to provide incontinence protection are designed to absorb body fluids, including urine.

These absorbent products typically have an absorbent placed between the liquid-permeable body-side cover and a liquid impervious separator. These absorbent products include an upper layer of the liquid-permeable body-side cover, a middle layer of the absorbent, and a lower layer of the liquid impervious facing separator. A pressure sensitive adhesive is typically secured to the separator. The pressure sensitive adhesive is used to bond the absorbent product to an inner crotch portion of a wearer's undergarment.

INTRODUCTION TO THE INVENTION Even though absorbent feminine care products are commercially available and are widely used today, a problem persists. runoff. Menstrual fluids drain around the sides of absorbent products for female care. Such lateral runoff stains the wearer's undergarments and outer garments.

Women today are attracted to wearing garments, including undergarments and outer garments, which are made of quality construction and fabrics. Staining by menstrual fluids usually ruins these garments made of quality fabrics having a quality construction.

Therefore, said draining of the menstrual fluids around the sides and an absorbent product for the care of the woman is a serious concern of the user of the absorbent product for the care of the woman.

The lateral fins, the appendages, the wings, and other lateral constructions added on the absorbent product for the care of the woman have had some success in absorbing the lateral discharge of the menstrual fluids, but they do not always absorb or contain all the menstrual fluids, especially during periods of heavy flow. Lateral runoff, even with the lateral fins in place, is sometimes unavoidable and almost always results in spots on the wearer's undergarments. Nevertheless, Even when the side flaps are effective to protect the wearer's undergarments, an outer garment can often be stained.

Therefore, there is a need for an article of protection against of the spots and of a method that provides protection against lateral runoff around the sides of an absorbent product for the care of women. An article of protection against stains and a method are also necessary which avoid staining of undergarments and outer garments. A stain protection article and a method are also necessary which provide the wearer with a sense of comfort during use when complete absorbency and complete protection against runoff are necessary.

SYNTHESIS OF THE INVENTION Briefly, the present invention provides a stain-resistant strip article and a method for protecting an inner garment from lateral runoff around an absorbent article for female care, including a first stain-resistant strip having a first staple member. strip of protection sheet against stains and a first fist member for comfort strip and protection against stains aligned along the length of the first stain protection sheet strip member, wherein the first stab member of protective comfort against stains is shaped to accommodate a user's inner leg. A second stain-resistant strip has a second stain protection sheet strip member and a second stab comfort strip member against the stains aligned along the length of the second staple strip member. protection sheet against stains, wherein the second comfort and anti-stain fist strip member is shaped to accommodate a user's inner leg.

DETAILED DESCRIPTION OF THE PREFERRED INCORPORATIONS Referring now to FIGS. 1 and 2, a stain-resistant strips article 10 is shown as having a pair of stain-resistant strips 12 and 14 to be used in connection with the attachment to an undergarment of the wearer. A left stain resistant strip 12 is seen in FIG. 1 having a protection sheet member against stains 16 and a protective comfort cuff member against stains 18. The protective sheet member against the spots 16 is positioned on one side of the comfort and protection cuff member against the spots 18 and is aligned with the comfort and protection cuff member against spots 18 along the axis longitudinal XX. The blade protection member against stains 16 is attached to the comfort and protection cuff member against spots 18 by ultrasonic bonding, thermal bonding and / or adhesive bonding. In a preferred embodiment, the anti-stain protection sheet member 16 is attached to the protective comfort cuff member against stains 18 by pressure applied and thermally cured adhesive.

An adhesive strip 22 is provided around a perimeter of the protection sheet member against the spots 16 along three sides of the sheet member. protection against stains 16 which are not aligned with the protection comfort cuff member against stains 18.

A right smudge-resistant strip 14 as seen in Fig. 1 has a protection sheet member against the spots 26 and a protective comfort cuff member against the spots 28. The protection sheet member against the spots 26 is positioned on one side of the comfort and protection cuff member against the spots 28 and is aligned with the comfort and protection cuff member against spots 28 along the axis longitudinal XX. An adhesive strip 32 is provided around a perimeter of the protection sheet member against the spots 26 along the three sides of the protection sheet member against the spots, which are not aligned with the barrier member. fist of comfort and protection against stains 28.

The comfort and protection fist members against spots 18 and 28 have an inner length 34 and 36, respectively in a shape configured to accommodate the arcuate shape of the interior of a user's leg.

The stain resistant strips 12 and 14 of the present invention are attached to an inner edge of the garment inside by means of the adhesive strips 22 and 32 which stick to the fabric or other material of the undergarment.

The stain-resistant strips article 10 provides protection against stains to make women's underwear more resistant and last longer. The currently available women's undergarments are not resistant to stains. When a menstruating woman uses an absorbent pad for female care, it is still normal to have an overflow of menstrual fluids on undergarments and clothes. This overflow also occurs during the daily deposits. The stain-resistant strip article of the present invention provides the woman with a security against menstrual overflow, protecting the undergarment and clothes from staining leading to deterioration of the material.

It is an important aspect that the stain resistant strip article of the present invention is provided by a separate article of the absorbent article for the care of women. For example, provided by an article of protection against stains completely separate and completely discreet physically from the absorbent article for the care of women. I have found that when using commercially available absorbent articles for women's care, a consumer sometimes it experiences the lateral draining around the absorbent article for the care of the woman and such lateral draining, almost always provokes the staining of her undergarments or of her clothes. There are several reasons for the fact that in spite of everything, staining and runoff are experienced. These reasons are based on three components, which can not be controlled by the supplier of the absorbent articles for the care of women commercially available today. These three components are (1) the temperature, (2) the size of the body, (3) the attachment surface of the absorbent article for the care of the woman.

The supplier of the commercially available absorbent articles for the care of women today can not control the temperature at which absorbent articles for the care of women are used. When the temperature varies, the absorbent articles for the care of women currently available today do not work in such a way as to be fail-proof because the additional heat stresses the pad and causes it to deform.

The provider of commercially available absorbent articles for the care of women can not control the size of the user's body. When the body size varies, absorbent articles for the Today's commercially available women's care does not work in such a way as to be safe against flaws, due to variable thigh sizes and variable lengths and crotch widths that cause the absorbent article to adjust differently about each person.

The provider of the presently commercially available absorbent articles for the care of women today can not control the surface on which the wearer holds the absorbent article for female care. When the clamping surface varies, the absorbent articles for the care of women commercially available today do not work in such a way as to be safe against flaws because the nature of the different fabrics causes a variation of the stability of the pad attachment. For example, a quality spandex as a bonding surface functions differently from a cheap nylon as a fastening source, which functions differently than cotton as a bonding surface. The provider of the absorbent article for the care of women has no control over the material used as the -surface of union. The pressure sensitive adhesive of the absorbent article for the care of women works on a cotton fabric in a different way than it does on polyester.

When the currently available commercially available absorbent articles for women are applied to the undergarment, often the undergarment is grouped, for example, in a roller coaster pattern, and therefore the undergarment will not be completely protected against staining.

For these reasons, the currently commercially available absorbent articles for women's care never fully and fully carve. Therefore, an important aspect of the stain-resistant strip article and the method of the present invention is to provide a stain-resistant strip article separated from the absorbent article for the care of women.

The left strip 12 and the right strip 14 as seen in Figure 1 are shown as having a global rectangular shape, but the strips 12 and 14 may take the form of other contours, for example, such as by way of example a oval, a flat oval shape or a rectangle having arched ends, provided that the strips are attached to the undergarment with a sufficient surface area to provide a secure connection and that the comfort cuff provides a sufficient surface area to contain the fluids menstrual The protective sheet members against the spots 16 and 26 are composed of a sheet of material impervious to liquid or of a material which can absorb the overflow together with a lower sheet impermeable to the liquid, by way of example, a material of cellulose or coform thin and light. The comfort and protection cuff members against spots 18 and 28 are comprised of a stretchable material which gently grasps a user's leg, for example, in a manner as provided by the elastic barrier adhesive material. (EBA) The adhesive strips 22 and 32 are composed of a strip of pressure-sensitive adhesive material.

It has been found that the comfort and protection fist members against spots 18 and 28 are preferably composed of a stretchable material which has not been stretched. When the stretchable material is stretched before being placed in use, the comfort cuff does not work properly in the stain resistant article and method of the present invention, but rather pulls the undergarment fabric to an undesirably condition. wavy The elastic barrier adhesive (EBA) material as used in the comfort cuff members 18 and 28 of the stain-resistant strip article of the present invention is preferably formed from a layer of a material joined with yarn, a middle layer of blown film with stretch melt and another layer of yarn bonded material. It has been found that the stain-resistant strip article and the method of the present invention provide a stain-resistant comfort cuff member composed of an elastic barrier adhesive (EBA) material that works well to prevent staining and that it is significantly more comfortable and does not wear away for the wearer as other materials, such as the elastic alone or the elastic placed between the two layers of a nonwoven material.

Referring now to Figures 3 and 4, a stain resistant strip article 10 is shown as having a pair of "stain resistant" strips 12 and 14 to be used in connection with the attachment to an undergarment 20 of the wearer. A right stain-resistant strip 12 as seen in Figure 3 has a sheet-protecting member against stains 16 and a comfort and protective fist member against stains 18. Because the article of stain-resistant strips 10 is shown applied to the undergarment 20 in Fig. 3, the side designations 12 and 14 mentioned in Fig. 1 are inverted for Fig. 3. The sheet-protecting member against stains 16 is positioned on one side of the comfort and protection cuff member against the spots 18 and is aligned with the comfort and protection cuff member against the spots 18 along the longitudinal axis X-X. An adhesive strip 22 is provided around a perimeter of the protection sheet member against the spots 16 along the three sides of the protection sheet member against the spots 16 which are not aligned with the barrier member. fist of comfort and protection against stains 18. A left stain-resistant strip 14 as seen in figure 3 has a protection blade member against stains 16 and a comfort and safety cuff member. protection against stains 28. The stain protection sheet member 26 is positioned on one side of the comfort and protection cuff member against stains 28 and is aligned with the comfort cuff member and of protection against spots 28 along the longitudinal axis XX. An adhesive strip 32 is provided around a perimeter of the protection sheet member against the spots 26 along the three sides of the protection sheet member against the spots 26 which are not aligned with the barrier member. fist of comfort and protection against stains 28.

The comfort and protection fist members against spots 18 and 28 have an interior length 34 and 36, respectively, in a shape configured to accommodate an arched shape of an interior of a leg of a wearer.

The stain resistant strips 12 and 14 of the present invention are attached to the upper surface of the undergarment 20 by the adhesive strips 22 and 32 respectively, which are glued to the fabric or other material of the undergarment 20.

Referring to FIGS. 5 and 6, a stain-resistant strips article 10 is shown in relation to an absorbent article for the care of women 40, for example, a sanitary napkin for the care of women. The stain-resistant strip article and the method of the present invention also has application in other incorporations of absorbent articles, such as a panty liner for female care or a panty shield, an incontinent garment, a urinary shield or a pad under the arm. For purposes of illustration, the absorbent article 40 will be described as an absorbent article for female care.

The stain-resistant strip article 10 is shown as having a pair of stain-resistant strips 12 and 14 to be used in connection with the attachment to an undergarment 20 of the wearer. A right stain resistant strip 12 as seen in FIG. 5 has the ends 52 and 54 formed in an arched configuration. A strip resistant to the left spots 14 have the ends 56 and 58 formed in an arched configuration.

The absorbent article 40 is shown in position on the upper part of the stain-resistant strip article 10. The pressure-sensitive adhesive is placed in the middle of the underside of the absorbent article 40 to hold the absorbent article 40 in position in the upper part of the stain resistant strip article 10 of the present invention.

The absorbent article 40 includes a liquid impervious cover 42, an absorbent 44 and a liquid impervious separator 46. The absorbent 44 is positioned between the liquid-permeable cover 42 and the liquid-impermeable separator 46. The absorbent article 40 is constructed to forming layers of the liquid permeable cover 42, the absorbent article 44 and the liquid impervious separator 46, arranged vertically.

The liquid-permeable cover 42 is made of a material designated to functionally serve as the material which will be brought into contact with the wearer's body. The liquid-permeable cover 42 is made of a woven or non-woven, natural or synthetic material which is easily penetrated by body fluids. Preferred films are thermoplastic polymer made of polymers or polyethylene or polypropylene filaments.

The cover 42 has the openings (not shown) formed in the cover 42 to increase the rate at which body fluids penetrate through the cover 2 to the absorbent 44.

The absorbent 44 is hydrophilic and is made of cellulose fibers, wood pulp, regenerated cellulose, cotton fibers or a mixture of pulp and other fibers.

The absorbent 44 is usually elastic to allow the absorbent article 40 to easily bend without undue distortion.

The hydrocolloid material, commonly referred to as superabsorbents, can be added to the hydrophilic material to increase the absorption capacity of the absorbent article 40.

The absorbent article 40 provides service as a sanitary napkin, such as a pant liner, or a panty shield pad and is put in conjunction with the stain-resistant strip article 10. The liquid impervious separator 46 of the absorbent article 40 it faces an internal surface, for example, the face-to-body surface of the stain-resistant strip article 10.

^ .. The first sheet-protecting member 18 against the strip stains, the second sheet-protecting member 28 against the strip stains, and the separator 46 can be made of a polymeric film such as polyethylene, polypropylene, or cellophane, or they can be made from a two-component film. A preferred material is an ethylene-vinyl acetate / polyethylene co-extruded film. In one aspect, the first sheet-protecting member 18 against strip stains, the second sheet-sheet member 28 for protection against strip stains, and the spacer 46 can be constructed of a material permeable to the strip. liquid that has been treated or coated to make it impermeable to liquid.

The cover 42 and the separator 46 can be attached or held together, such as by a peripheral seal, to wrap the absorbent 44. The cover 42 can be wrapped completely around the absorbent 44 and then the separator 46 can be attached to the lower surface of the absorber 44. cover 42 by means of end seals.

The absorbent article 40 usually has an overall length of between about 6 to 12 inches (from 15 to 30 cm) and a width of between about 2 to 3.5 inches (from 5 to 9 cm), sometimes from 1.5 to 3.5 inches (from 4 to 9 cm). He The thickness of the absorbent article 50 can vary from about 2 mm to about 1 inch (2.5 cm).

The stain-resistant strips article 10 used in combination with the absorbent article 40 usually has an overall length of between about 4 to 15 inches (from 10 to 38 cm) and a width of between about 1.5 to 4 inches. (from 3.5 to 10 cm), sometimes from about 4 to 10 inches (from 10 to 25 cm). The thickness of the stain resistant strip article 10 can vary from about 1 mm to about 0.5 inch (1.5 cm).

Referring now to Figures 7 and 8, there is shown a stain-resistant strips article 10 with an absorbent article for female care 40, for example, such as a sanitary towel for the care of women, in a combination pack. 60 The combination pack 60 has a bag 62 formed by matching the sides 12 and 14 of the stain-resistant strip article 10. The absorbent article 40 is encased in the bag 62.

Referring now to FIGS. 9 and 10, the stain-resistant strips article 10 is folded in a triple fashion to form an article of strips resistant to spots 80 shown with an absorbent article for the care of women folded in triple form 72, for example, such as a sanitary towel for the care of women folded in triple form, in a combination pack 90.

The stain-resistant strip on the left side 14 as shown in FIG. 9 is overlapped on the stain-resistant strip on the right side 12. The absorbent article folded in triple form 72 has a first bend end 74 and a second end folded 76. The absorbent article 72 is folded in a triple form, for example, folded twice to form the folded members in a triple fashion by forming a folded absorbent article measuring about three inches by three inches (8 cm by 8 cm).

The triple-folded absorbent article 72 is placed in the middle of the stain-resistant strip article 10, as shown in FIG. 9, having the overlapped strips 12 and 14. The overlaid stain-resistant strip article 10 it has an end 82 and an opposite end 84. The triple-folded absorbent article 72 is positioned between an end 82 and the opposite end 84 of the overlapping stain-resistant strip article 10.

The stain-resistant strips article 10 is then folded in triple form, for example, folded two times to form the folded members in a triple fashion by forming a folded absorbent article. The stain resistant strips article folded into triple 80 has one end 82 and one opposite end 84. The stain resistant strip article folded into triple 80 has an adhesive 86 applied to one end 82 to hold it in place in a triple-folded condition on the opposite end 84. The adhesive has a light tack so that the stain-resistant strips can be unfolded and used to protect the wearer's undergarments in the manner of the method of the present invention. . In one embodiment, the pressure sensitive adhesive 22 and / or the pressure sensitive adhesive 32 can serve the function of the adhesive 86 to hold the stain resistant strip article 80 temporarily in a triple-folded condition, and then in that embodiment, the adhesive 86 is replaced by the pressure sensitive adhesive 22 and / or 32 of the stain resistant strip article 80.

In Fig. 10, a triple-folded anti-stain protection article 80 is shown folded in a triple fashion around a triple-folded, folded women's absorbent article 72. Thus, a combination pack 90 of the present invention is shown having a triple-folded anti-stain protection article 72 and an absorbent article for the care of women folded in triple-80 form.

The triple-folded absorbent 72 is encased in the center of the item of stain-resistant strips folded in a triple 80 fashion as shown in Fig. 10.

The absorbent article 40 and 72 as used in combination pack 60 and 90 of the present invention may be formed in the configuration of a racing track or similar oval. The absorbent article 40 and 72 may have other shapes, for example, such as rectangular shapes other than oval, to the race track shape, provided the shapes are designed to cover the pudenda region of a woman. The absorbent article 40 can be seen as having a central longitudinal axis X-X. Most absorbent pad items, such as sanitary napkins and pant liners or shields, are layered into sheets that are larger or are wider. In addition to the liquid permeable cover 42, the absorbent 44 and the separator 46, other layers may also be used, such as a transfer layer, a layer of anhydrous deodorant material, a layer containing superabsorbent materials, and additional absorbent layers.

The various layers can be stacked vertically, assembled, laminated and / or joined together to form the sheet or fabric of material from which the articles are then cut or stamped, prior to fastening the separator "Ja- I i impermeable to the liquid of the present invention. The various layers can be joined together by the use of heat, pressure, heat and pressure, adhesive, hot melted gum, sewn with thread, ultrasonic bonding, mechanical bonding, thermal bonding, chemical bonding, or a combination of these and / or other means known to those skilled in the art.

The first member 18 of sheet of protection against strip stains, the second member 28 of sheet of protection against strip stains, and the separator impermeable to liquid 46 can be designed to allow the passage of air or of the Steam out the absorbent items while blocking the passage of body fluid. The first strip sheet member against stains 18, the second strip sheet member against stains 28 and the liquid impervious strip 46 can be made of any material having these properties. The first strip sheet member against stains 18, the second strip sheet member against stains 28, and the liquid impervious strip 46 can also be constructed of a material which will block the passage of steam as well as fluids if desired. A good material from which the first protective sheet strip member can be constructed against the spots 18, the second protective sheet strip member against the spots 28, and the liquid impervious separator. 46 is a micro-etched polymeric film, such as polyethylene or polypropylene. Two-component films can also be used. A preferred material is a polyethylene film. More preferably, the polyethylene film will have a thickness in the range of from about 0.5 mils to about 2.0 mils.

The construction adhesive can be used in the articles of the present invention to hold and join the various layers together. For example, referring to Figure 6, a construction adhesive can be used to attach the liquid impervious separator 46 to the absorbent 44 or to attach the absorbent 44 to the liquid-permeable cover 42. The presence of such an adhesive construction and the Quantity used will depend on manufacturing specifications. Useful construction adhesives are commercially sold by National Starch and Chemical Company, having an office located at 10 Finderne Avenue, Bridgewater, New Jersey 08807.

The liquid-permeable cover 42 is designed to make contact with the wearer's body and can be constructed of a woven or non-woven material which is easily penetrated by body fluid. The liquid permeable cover 42 can also be formed of either natural or synthetic fibers. Suitable materials include carded and bonded polyester, polypropylene fabrics, polyethylene, nylon or other fibers that can be bonded with heat. Other polyolefins, such as polypropylene and polyethylene copolymers, linear low density polyethylene, finely perforated film fabrics and network materials, also work well. A preferred material is a composite of a perforated thermoplastic film placed on top of a nonwoven fabric material. Such a composite material can be formed by extruding a polymer onto a fabric of a spunbonded material to form an integral sheet. An example of this material is a perforated thermoplastic polyethylene film bonded to a spin-bonded material. The yarn-bound material is a non-woven material which is manufactured and commercially sold by Kimberly-Clark Corporation having an office located at 401 North Lake Street, Neenah, Wisconsin 54956. The non-woven / perforated film laminate exhibits a smooth appearance and It is soft to the touch. This material is soft and does not irritate the wearer's skin and still has a cushioned feeling due to its volume. Another useful material such as the liquid permeable cover 42 is a fabric bonded with polypropylene yarn. This spunbond fabric can contain from about 1 percent to about 6 percent of a bleaching agent, such as titanium dioxide (T? 02) or calcium carbonate (CaCO3) to give it a clean white appearance. A uniform thickness of the yarn bond is desirable because it will have sufficient strength, after being punched, to resist being torn or pulled and separated during use. "The most preferred polypropylene fabrics have a basis weight of between about 18 grams per square meter (g / m2) to about 40 g / m2. An optimum weight is between about 30 g / m2 to about 40 g / m2.

The absorbent layer 44 can be present as a single layer or as two or more different layers. The absorbent layer 44 can be formed of various natural or synthetic fibers such as wood pulp fibers, virgin cellulose fibers, regenerated cellulose fibers, cotton fibers, swamp moss or a mixture of pulp and other fibers. fibers. The absorbent layer 44 may also be formed of a fine pored fabric such as an air dried and wet laid tissue or a non-creped continuous air drying tissue (UCTAD) having a basis weight of from about from 30 g / m2 to around 120 g / m2. The UCTAD tissue can be prepared by a process described in U.S. Patent No. 5,048,589 issued to Crook et al. On September 17, 1991. The UCTAD tissue is described in the United States patent of America No. 5,399,412 issued to Sudall et al. On March 21, 1995. Each of these patents is incorporated herein by reference and is hereby incorporated herein by reference. The absorbent layer 44 may also comprise other well known materials such as cellulose fibers, rayon fibers, cellulose sponge, hydrophilic synthetic sponge, polyurethane for example, and the like.

The absorbent article 40 also includes one or more elongated areas or strips of a bonding adhesive secured to the lower surface of the liquid permeable separator 46. The bonding adhesive functions to attach the absorbent article 40 to the crotch portion inside of the undergarment 20 and to overlap a part of the article resistant to stains 10. The bonding adhesive can cover a part of the lower surface of the separator impermeable to liquid 46.

The bonding adhesive 22 and 32 of the stain resistant article 10 and the female care absorbent article 40 may consist of a swirl pattern of adhesive or may be one or more strips of adhesive or various other patterns. The bonding adhesive may also consist of a plurality of spots of adhesive which are uniformly or randomly arranged on the outer surface of the first protection sheet member 18 against the strip spots., of the second protection sheet member 28 against the strip stains and separator 46.
