Definitions
- This invention relates to a sanitary protection absorbent article designed to protect a user by absorbing or containing menstrual fluids and/or other body exudates and further relates to a method of wrapping the absorbent article. More specifically, this invention relates to an integrally wrapped sanitary protection absorbent article and method of wrapping which provide an integral pad wrapping around an individual feminine care sanitary absorbent pad.
- Feminine sanitary protection devices designed to absorb body fluids, including menses come in different functional designs. Sanitary napkins externally worn about the pudendal area are absorbent pads designed primarily for heavy menstrual flow. Panty liners or panty shields are thin sanitary napkin products worn about the pudendal area for light menstrual flow. Tampons are cylindrical absorbent pads positioned internally within the vagina.
- sanitary napkins have been bundled with several napkins in each package. A single, large package is called on to keep all the napkins clean, sanitary, and undamaged. Unfortunately, however, when one napkin is removed from the package and carried individually in a pocket or purse, it becomes unprotected from dirt and deforming pressures.
- this invention relates to an integrally wrapped absorbent article including an absorbent having a first sheet surface and an opposite second sheet surface, the first sheet surface having a length and a width configured to fit the pudendal region of a woman.
- a liquid-impermeable baffle is secured to the first sheet surface, the baffle having a length and a width covering the first sheet surface, wherein the baffle width further extends beyond the width of the first sheet surface by less than about one inch.
- a means for garment attachment includes a garment-attachment adhesive for securing the liquid-impermeable baffle to an inside surface of a crotch of an undergarment and a releasable peel strip covering the garment-attachment adhesive.
- An enclosure surrounds the adsorbent, wherein the enclosure is formed from the liquid-impermeable baffle.
- a method of wrapping the absorbent article includes the steps of providing an absorbent article having a liquid-permeable cover sheet, an absorbent, and a garment-attachment adhesive, the adsorbent having a length and a width configured to fit the pudendal region of a woman; positioning a liq- uid-impermeable baffle between the absorbent and the garment- attachment adhesive, the baffle having a length and a width covering the adsorbent, wherein the baffle width further extends laterally larger than the adsorbent pad width by less than about one inch; forming an enclosure surrounding the adsorbent, wherein the enclosure is formed from the liquid-impermeable baffle; and providing a removable release strip covering said garment adhesive layer.
- the integrally wrapped absorbent article provides sani- tary protection and includes a sanitary napkin, panty liner or panty shield having a folded adsorbent pad of an unfolded length and a width configured to fit the pudendal region of a woman.
- an attachment adhesive patch holds the absorbent pad in the folded condition, wherein the adhesive patch is formed by the release strip covering the garment adhesive layer.
- the release strip has an aperture exposing a portion of the garment adhesive layer
- the liquid-impermeable baffle has a first lateral side on one lateral side of the baffle width and a second lateral side on the opposite lateral side of the baffle width, opposite the first lateral side.
- the first lateral side is sealed along its length to form a first side seal
- the second lateral side is sealed along its length to form a second side seal, such that the first and the second lateral sides and the first and the second side seals form the enclosure of the integrally wrapped absorbent article of the present invention.
- a first perforation strip on the first side seal and a second perforation strip on the second side seal make it convenient for opening the individually wrapped package of the present invention.
- a feminine sanitary protection package is needed which provides an absorbent article having a sanitary napkin, panty liner or panty shield with individual wrapping without added manufacturing and material production costs.
- a feminine sanitary protection package also is needed which provides for a less expensive absorbent article to be stored discreetly until use and which prevents soiling, con- tamination and deformation.
- a general object of this invention is to provide an integrally wrapped absorbent article capable of absorbing and containing menstrual fluids and/or other body exudates.
- a more specific object of this invention is to provide an integrally wrapped absorbent article which is individually wrapped. Another object of the present invention is to provide an individually wrapped sanitary napkin or panty liner or shield having packaging and manufacturing cost advantages.
- a further object of the present invention to provide individually wrapped sanitary napkin or panty liner or shield which uses less plastic material that is thrown away.

- the integrally wrapped sanitary protection absorbent article provides individual wrapping for protective, absorbent sanitary napkins and panty liners or shields for undergarments.
- the individually wrapped absorbent article provides for cleanliness and discretion in handling prior to use.
- an integrally wrapped absorbent article initial configuration 1 includes an absorbent pad 10 having an exterior profile in the shape of an hourglass.
- the absorbent pad 10 includes a liquid-pervious cover 12 and an absorbent 14.
- a liquid-impermeable baffle 16 of the integrally wrapped absorbent article initial configuration 1 is designed to permit the passage of air or vapor out of the absorbent pad 10 while blocking the passage of body fluid.
- Such sanitary napkin and panty liner or shield pads 10 are designed for adhesive attachment to the inside surface of the crotch portion of an undergarment.
- the absorbent articles 10 are constructed from layers of a liquid-permeable cover 12 and an absorbent 14, vertically arranged.
- the liquid-impermeable baffle 16 is constructed and utilized as the individual absorbent pad wrapper.
- the liquid- impermeable baffle 16 can provide the individual absorbent pad wrapper because of an extra poly film width located along both a first side 22 and a second side 24 of the baffle 16.
- the first side 22 is situated on one side of the baffle 16 width as viewed relative to the longitudinal axis X-X, and the second side 24 is situated on the other side of the width of the baffle 16, opposite to the first side 22.
- the first side 22 and second side 24 of the baffle 16 have a dimension which extends beyond the width of absorbent pad 10. Even though the larger width of baffle 16 will be used to enclose the absorbent pad 10, the dimension of first side 22 and second side 24 of the baffle 16 which extends beyond the width of absorbent pad 10, however, is not required to be sufficient to fold completely over the absorbent pad 10.
- the larger width of baffle 16 need only be on the order of less than one inch on each side, for example, which extends beyond the width of absorbent pad 10.
- a garment attachment adhesive 18 is secured to a lower surface of the baffle 16, and the adhesive 18 can be covered by a removable release strip 20.
- the individually wrapped adsorbent article 30 of the present invention is shown as it is folded, enclosed, and sealed, and then how it is opened, unfolded, and deployed for use.
- the individually wrapped adsorbent article 30 of the present invention is folded in such a way that the extra width of the poly baffle 16 can be folded and 22 and 24 bonded together, effecting the seals 22 and 24 for a wrapped appearance.
- the liquid-impermeable baffle enclosure 16 encloses the absorbent pad wherein the first side 22 is sealed along its length to form a first side seal 26, and the second side 24 is sealed along its length to form a second side seal 28.
- the first side 22 and the first side seal 26 and the second side 24 and the second side seal 28 form the baffle enclosure 16 of the individually wrapped absorbent pad 30.
- a perforation 32 is formed on the first side 22, and a perforation 34 is formed on the second side 24 as shown in Figure 3.
- These perforations 32 and 34 allow the extra mate- rial of the baffle 16 poly to be torn away to unwrap the absorbent article 30 as shown in Figure 4.

- a preferred embodiment of the integrally wrapped absorbent article of the present invention includes an extended release strip 110 to hold down a free end 112 of a absorbent article 114.
- Figure 16 shows the release strip 110 or peel strip 110 extending past one end 112 of the absorbent article 114.
- Figure 17 shows a patch 116 of adhesive on the extended peel strip 110, and an arrow indicates that the peel strip 110 is wrapped around the folded end 118 of absorbent article 114.
- Figure 18 shows the extended peel strip 110 wrapped around the folded end 118 of the absorbent article 114 and attached to itself, i.e., attached to another position on peel strip 110.
- the extended peel strip 110 wrapped around the folded end 118 of the absorbent 114 and attached to itself holds the free end 112 of the absorbent article 114 in place and also presents a neater appearance, i.e., an appearance of high quality fit and finish.
- the absorbent pad as used in the integrally wrapped article of the present invention can be formed in the shape of a race track or oval or the like.
- the absorbent article pad can have other shapes, e.g., such as rectangular shapes other than oval or race track shape, pro- vided that the shapes are designed to cover the pudendal region of a woman.
- the absorbent pad can be viewed as having a central longitudinal axis X-X.
- Most absorbent pad articles such as sanitary napkins and panty liners or shields, are layered in sheets which are longer than they are wide.
- other layers also can be utilized, such as a transfer layer, a layer of anhydrous deodorant material, a layer containing super-absorbent materials, and additional absorbent layers.

- the liquid-permeable cover 12 also can be formed from either natural or synthetic fibers. Suitable materials include bonded carded webs of polyester, polypropylene, polyethylene, nylon, or other heat-bondable fibers. Other polyolefins, such as copolymers of polypropylene and polyethylene, linear low- density polyethylene, finely-perforated film webs and net materials, also work well.
- a preferred material is a composite of an apertured thermoplastic film positioned above a non- woven fabric material.
- Such a composite material can be formed by extrusion of a polymer onto a web of spunbond material to form an integral sheet.
- this material is an apertured, thermoplastic polyethylene film bonded to a spunbond material.
- Spunbond material is a non-woven material which is manufactured and commercially sold by Kimberly-Clark Corporation having an office located at 401 N. Lake Street, Neenah, Wisconsin 54956.
- the apertured film/non-woven laminate exhibits a smooth appearance and is soft to the touch. This material is soft and does not irritate the wearer' s skin and yet has a cushioned feel because of its bulk.
- Another material useful as the liquid-permeable cover 12 is a spunbond web of polypropylene.
- This spunbond web can contain from between about 1 percent to about 6 percent of a whitening agent, such as titanium dioxide (Ti0 2 ) or calcium carbonate (CaC0 3 ) to give it a clean, white appearance.
- a whitening agent such as titanium dioxide (Ti0 2 ) or calcium carbonate (CaC0 3 ) to give it a clean, white appearance.
- Ti0 2 titanium dioxide
- CaC0 3 calcium carbonate
- a uniform thickness of spunbond is desirable because it will have sufficient strength, after being perforated, to resist being torn or pulled apart during use.
- the most preferred polypropylene webs have a basis weight of between about 18 grams per square meter (g/m 2 ) to about 40 g/m 2 . An optimum weight is between about 30 g/m 2 to about 40 g/m 2 .
- the absorbent layer 14 can be present as a single layer or as two or more distinct layers.
- the absorbent layer 14 can be formed from various natural or synthetic fibers such as wood pulp fibers, virgin cellulose fibers, regenerated cellu- lose fibers, cotton fibers, peat moss, or a blend of pulp and other fibers.
- the absorbent layer 14 also could be formed from a fine pore fabric such as wet-laid, air-dried tissue or from an uncreped through air-dried (UCTAD) tissue having a basis weight of from about 30 g/m 2 to about 120 g/m 2 .
- the UCTAD tissue can be prepared by a process disclosed in U.S. Patent No. 5,048,589 issued to Crook et al. on September 17, 1991.
- the UCTAD tissue is disclosed in U.S. Patent No. 5,399,412 issued to Sudall et al . on March 21, 1995. Each of " these patents is incorporated by reference and made a part hereof.
- the absorbent layer 14 also may be comprised of other well-known materials such as cellulose fibers, rayon fibers, cellulose sponge, hydrophilic synthetic sponge, for example polyurethane, and the like.
- the absorbent articles 10 also include one or more elon- gated strips or areas of a garment attachment adhesive 18, for example, referring to Figure 2, secured to the bottom surface of the liquid-permeable baffle 16.
- the garment attachment adhesive 18 functions to attach the absorbent articles 10 to the inner crotch portion of an undergarment during use.
- the garment attachment adhesive 18 enables the sanitary napkin or panty liner to be properly aligned and retained relative to the user' s vaginal opening so that maximum fluid protection can be obtained.
- the garment attachment adhesive 18 can cover a portion of the bottom surface of the liquid-impermeable baffle 16.
