    FIELD OF THE INVENTION
    [001] The current invention is related to fixation systems for absorbent articles of personal care. More particularly, it relates to absorbent personal care articles with folding wings or flaps that can be used to properly position and attach the absorbent articles to underwear or other articles of clothing. HISTORIC
    [002] Absorbent personal care items, such as feminine pads and incontinence pads, usually use a pair of wings or flaps to help attach the item to the wearer's underwear. Generally, the wings are folded and attached to the outside of the user's underwear through adhesives or other means of attachment. When attached to underwear, the wings help to reduce the likelihood of the article moving out of position. There are descriptions and images of examples of such folding fixing wings in US4589876 Van Tilberg; EP051190B1 Pigneul; US5401268 Rodier; and EP1208823A1 Hohmann.
    [003] However, although wings of various sizes and shapes have been used previously, there are still many drawbacks in these designs. First, many wings do not adequately prevent the article from being heaped or folded due to the stress applied on the article by the user's movement. Second, incorrect application of the article to underwear can also greatly increase the risk of leakage. In this sense, it may be difficult for users to apply conventional wings properly to their underwear and, when the wings are improperly attached, the absorbent article may pile up or partially fold when worn, or fold or pile up more easily due to movement of the user. Bending or deformation of the article when worn can result in an angular positioning in relation to the user, as opposed to a perpendicular or flat position in relation to the user. When the article is folded laterally in relation to the user, the article's ability to capture and absorb fluids can be reduced in such a way that the article works very differently from the desired one. In addition, grouping the article results in much less coverage than desired under the vaginal region. Thus, these unwanted folds and grouping of the article can result in an increase in the frequency of leakage and spots in the user's clothes.
    [004] Thus, there is a constant need for an absorbent article of personal care with folding wings that assist the user with the correct positioning and placement of the article. There is still a need for an article like this, in which the folding wings also help to keep the article in a non-twisted and / or flat shape in order to minimize the incidence of leakage. SUMMARY OF THE INVENTION
    [005] The current invention solves problems faced with previous flap designs by providing an absorbent personal care item that includes (i) a left flap with a first and a second end and a groove positioned in the middle, and (ii) a flap right with a first end. The right and left flaps are positioned on opposite longitudinal sides of the article and are of a size that, when folded under the article and extended so that they are flat against the impermeable backsheet, the end of the right flap extends over the center line longitudinal section of the article and fits in the groove of the left flap.
    [006] In another aspect of the invention, the left and right flaps can integrally assume a shape and size that cause the wings to interconnect or fit when folded under and around the article. In yet another configuration, the left and right flaps can define a space or gap between them along the length of the flaps, when they are folded under the article, being flatly adjacent to the impermeable backsheet. In an alternative configuration, the left and right flaps can be sized or shaped so that they form one or more discrete areas of overlap when folded under and around the article and remain flat adjacent to the impermeable backsheet.
    [007] In another aspect of the invention, the right and left flaps may include fasteners located on the side of the flap end facing the article of clothing, such that the fastener extends along the longitudinal center line of the article and to inside the groove of the opposite flap or on the opposite flap. This can be achieved, in one configuration, by placing the fastener close to the outer edges of the flap ends. BRIEF DESCRIPTION OF THE DRAWINGS
    [008] FIGURE 1 is an upper section view partially representative of a configuration of an absorbent of the current invention in a flat and unfolded state.
    [009] FIGURE 2 is a plan view representing an absorbent in an alternative configuration of the current invention, suitable for use with traditional underwear and thong style.
    [010] FIGURES 3 to 6 are enlarged views of individual wing configurations of the current invention, displayed in an interlaced relationship, folded directly under the personal care article and flat in relation to the impermeable backsheet. DESCRIPTION OF THE INVENTION
    [011] With respect to Figures 1 and 2, the drawings show absorbent articles of personal care in a flat and unfolded state. Unless otherwise stated, the discussion about the dimensions of the article and / or the positions of the individual components of the article refer to the article in a flat and unfolded state and, in the case of the use of elastic components, the dimensions refer to the article in question. an uncontracted state. In addition, as used herein, the terms "formed" or "including" are inclusive or open and do not exclude additional elements not mentioned, components of composition or steps of the method. Consequently, the terms "formed" or "including" encompass the more restrictive terms "formed essentially by" and "formed by".
    [012] With reference to FIGURE 1, a personal care absorbent article 10 is provided, formed by a permeable top sheet 12, an impermeable back sheet 14 and an absorbent core 16. The absorbent article 10 has a length direction or a longitudinal direction and a wide direction or transverse direction. The longitudinal centerline of Article 10 is displayed as the "L" line and the transverse centerline of Article 10 is displayed as the "T" line. The absorbent article 10 can be formed by any one of several elongated shapes, including, without limitation, the triangular, rectangular, elliptical and canine bone shapes. In addition, it will often be desirable for the article to have rounded corners and / or generally convex ends. The desirable absorbent article is approximately 80 to 450 millimeters long. Even more desirable is a length of approximately 150 to 250 millimeters. The desirable absorbent article 10 has a maximum width (without the wings) of approximately 40 to 160 millimeters. Even more desirable is a maximum width of approximately 65 to 95 millimeters.
    [013] The absorbent article 10 further includes a first wing 20 and a second wing 30 that extend from the opposite longitudinal sides of the article 10. The first and second wings 20, 30 have an extension of approximately approximately 20% to 75% the length of article 10. In yet another aspect, the wings have a desirable length, in the longitudinal direction L, of approximately 40 to 160 mm. Even more desirable is a length of approximately 95 to 145 mm. The wings can be positioned on the transverse center line or can be positioned some distance ahead or behind the transverse center line, as desired, in order to better accommodate the specific shape of the article and / or use in a specific style of clothing. In addition, although it is not displayed, it is realized that absorbent articles may, if desired, contain more than one set of opposite wings of the current invention
    [014] A portion of the outer surface of the wings 20, 30 includes one or more fasteners 26, 36. The fastener will be selected to be removably attached to a garment or overlapped with an opposite wing. Various adhesives and mechanical hook-type fasteners that are removably attached to themselves or to a person's clothing are well known in the art and are suitable for use in conjunction with the current invention. Pressure sensitive adhesives are particularly suitable for use with the current invention. However, in order to protect the adhesive from contamination or drying before use, the adhesive is normally protected by one or more peelable strips known in the art. A suitable peelable strip is white kraft paper with a silicone coating on one side, so that it can be easily removed from the adhesive. In addition, with respect to wing-to-wing fastening, examples of specific mechanical hooks, adhesives or other fastening systems include, but are not limited to, those described in WO03 / 015682 for Hammonds and others; WO03 / 015684 to Hammonds et al. And US2004013317 to Steger et al.
    [015] The first wing 20 includes at least a first end 21 and a second end 22 and a base of the groove 24 covering the ends; the inner edges of the first and second ends 21, 22 and the base of the groove 24 define a groove or groove 24A in the first wing 20. The shapes of the ends and groove (s) can vary as desired, including straight configurations and curvy. The wing 20 and its components are dimensioned in such a way that when the wing 20 is folded around the underside of the article and the wing 21 is flat against the backsheet 14, parts of the first and second ends 21, 22 they extend along the longitudinal central line L, while the base with groove 24 is not extended by or to the longitudinal central line. Thus, the specific dimensions of the wings will be selected in relation to the corresponding width of the absorbent article. In one aspect, the dimension of the end in the transverse direction can be at least 50% of the width of the adjacent section of the absorbent core. In yet another aspect, the desirable distance from the middle of the first end to the middle of the base of the groove 24 is at least 20. Even more desirable is approximately 20 to 60 millimeters.
    [016] The second wing 30 includes at least one first end 31 and the first and second shoulders 38, 39 positioned on opposite sides of the first end 31 of the second wing 30. The individual elements of the second wing 30 may have dimensions equal to or similar to those of the first wing 20. However, as will be discussed in more detail below, the ends, grooves and / or shoulders of the first and second wings are shaped to coincide with each other. The second wing 30 and its components are dimensioned in such a way that when the second wing 30 is folded around the underside of the article and is flat against the backsheet 14, parts of the first ends 31 extend along the center line longitudinal L, while shoulders 38, 39 are not extended by the longitudinal centerline L or to it. The shapes of the extremities, grooves and / or shoulders can vary as desired, including straight and curvilinear configurations.
    [017] The first and second wings 20, 30 are positioned along the longitudinal sides of the article 10, while the base of the groove 24 of the first wing 20 is on the same plane as the first end 31 of the second wing. In other words, the first and second wings 20, 30 are positioned along the opposite longitudinal sides of article 10 such that when the first and second wings 20, 30 are folded around the bottom side of article 10 and extended in order to be flat in relation to the backsheet 14, the first end 31 of the second wing 30 extends to the groove 24A of the first wing 20 (the groove 24A of the first wing 20 being defined by the ends 21, 22 and the base of the groove 24).
    [018] In one configuration and with reference to FIGURE 3, the first and second wings 20, 30 can be dimensioned and shaped so that, when folded around the bottom side of article 10 and extended to be flat in relation to the back sheet 14, the wings 20, 30 do not overlap, leaving a space or gap "G" between them. In the configuration shown, the wings 20, 30 are dimensioned and molded so that they substantially intertwine, but leave a substantially uniform "G" gap between them when folded around the underside of the article, so that they are flat in relation to the backsheet 14. In such configurations, the wings leave a desirable “G” gap of less than approximately 20 millimeters and, even more desirable, of approximately 15 millimeters. Thus, in use, the first wing 20 and the second wing 30 extend around the crotch portion of the garment, and the first end 31 of the second wing 30 extends in the groove 24A of the first wing 20 in a coupling relationship. In another aspect, the first and second ends 21, 22 of the first wing 20 and the shoulders 38, 39 of the second wing 30 have a correspondingly similar relationship with a similar gap between the respective edges. The main fasteners 26, 36, like a pressure sensitive adhesive, can be positioned adjacent to the outer edges of the ends such that, when the wings 20, 30 are folded under the article so that the wings 20, 30 are flat with respect to the backsheet 14, the fasteners 26, 36 are on the opposite side of the longitudinal centerline relative to which the wing is attached. The wings can also optionally include the secondary fasteners 27, 37 located close to the outer edges of the base of the groove 24, the shoulders 38, 39 or the base of the ends 21, 22, 31. The main fasteners 26, 36 can be total or partially beyond the longitudinal center line when the wings 20, 30 are folded around the underside of the article 10 and are flat and relative to the backsheet 14. As shown in FIGURE 3, when the wings 20, 30 are folded around the bottom side of article 10 and are flat in relation to the backsheet 14, the main fasteners 26, 36 are positioned entirely on the opposite side of the longitudinal central line "L" relative to the side from which the wing extends.
    [019] In another configuration, and with respect to FIGURES. 4 and 5, the first and second wings 20, 30 are dimensioned and shaped so that they form overlapping regions 50 when folded around the bottom side of the article 10 and extended to be flat in relation to the backsheet 14. Thus, in use, the first wing 20 and the second wing 30 can extend around the crotch portion of the garment, and the first end 31 of the second wing 30 extends over the base of the groove 24 of the first wing 20 in an overlapping relationship. In this configuration, the wings are dimensioned and molded so that there is an interrelation so that they are superimposed. When the wings 20, 30 are folded over the lower side of the article 10 to be flat in relation to the backsheet 14, the overlapping individual regions 50 formed by the overlapping parts of the first wing 20 and the second wing 30 have a desirable area of at least 50 millimeters2 or, more desirable, approximately 50 to 600 millimeters2 and, even more desirable, between 100 and 250 millimeters2 approximately. In a specific configuration and with respect to Figure 4, the dimension of the wings in relation to the width of the article 10 (with the exception of the wings) is such that the first and second wings 20, 30 form overlapping regions 50 adjacent to the outer edges of the ends 21, 22 and 31, and generally extend in the longitudinal direction. In a specific configuration and with respect to FIGURE 5, the shape and dimension of the wings 20, 30 in relation to the width of the article 10 (with the exception of the wings) are such that the first and second wings 20, 30 form adjacent overlapping regions 50 to the lateral edges of the ends 21, 22 and 31 and generally extend in the transverse direction T. The wings 20, 30 can include fasteners (not shown) positioned in one or both areas of the wings that will overlap and come into direct contact with each other. the other. The fasteners are positioned adjacent to the edges of the ends 21, 22, 31. Optionally, the wings can include secondary fasteners, such as a pressure sensitive adhesive, located in one or more areas of the wings 20, 30 and which will overlap the clothing when dressed.
    [020] In another configuration and with respect to FIGURE 6, the second wing 30 may have the same or very similar shape to that of the first wing 20. Thus, in the present configuration, the first 20 and the second wing 30 have first ends 21 , 31 and second ends 22, 32 and groove bases 24, 34, respectively. The first ends 21, 31 and the second ends 22, 32 are dimensioned so that they extend beyond the longitudinal centerline "L" when the wings 20, 30 are folded under the back side of the article and extended so that they are flat in with respect to the backsheet 14. In addition, the wings 20, 30 are spaced apart from each other so that when they are folded around the underside of the article and extended to be flat with respect to the backsheet 14, the first end 31 of the second flap 30 extends to the groove of the first wing 20 and the first end 21 of the first wing 20 extends to the groove of the second wing 30. As will be readily understood by a skilled person, the various wing ends can be configured to have non-overlapping relationships, overlapping relationships, or both. Consequently, the wings will contain several fasteners according to the fastening mechanism and the selected overlapping scheme. With reference to FIGURE 6, the main fasteners 26, 36 cross the longitudinal central line "L".
    [021] The front and rear halves of each wing can be symmetrical or asymmetrical, as desired. For example, in one configuration and in relation to FIGURE 1, the front and rear halves of the wings, that is, the halves above and below the transverse centerline in the longitudinal direction, are symmetrical. The absorbent core in the configuration of FIGURE 1 is also symmetrical and it will generally be desirable for its wings to be symmetrical when the absorbent core is symmetrical. In an alternative configuration and with reference to FIGURE 2, the absorbent core 16 is molded with a wider front part (F) and a narrower back part (R) in order to better suit a type of underwear like thong type and also for use and connection with certain night cushions. The wings are thus configured to correspond with the difference in the width of the article 10. More specifically, the first end 21 of the first wing 20, which is positioned adjacent to a wider section of the absorbent core 16, has a dimension greater in the transverse direction than the second rear end 22 of the first wing 20. In the configuration shown in FIGURE 2, the wings 20, 30 are centered on the transverse center line "T" of the article. However, as previously indicated, the wings 20, 30 can be positioned further away or closer to the transverse center line, as desired.
    [022] With regard to the general function and composition of Article 10, the backsheet or outer cover 12 works to isolate the liquids absorbed from the user's underwear and, therefore, is made of an impermeable material. In one aspect, the external cover can optionally be formed by a material that prevents the passage of liquids, but that allows the entry of air and water vapor. The outer cover can be formed by a single layer or by several layers and these layers can be formed by similar or different materials. Suitable materials for the backsheet include, without limitation, polyolefin films, non-woven fabrics and film / non-woven laminates. The specific structure and composition of the outer cover can be selected from several known films and / or fabrics, with the specific material being selected as appropriate, in order to provide the desired level of liquid barrier, strength, abrasion resistance, tactile properties , aesthetics, etc. Suitable external covers include, without limitation, those described in US4578069 for Whitehead and others; US4376799 to Tusim and others; US5695849 to Shawver et al; US6075179 and others for McCormack and others; and US6376095 to Cheung et al.
    [023] The top sheet 14 works to receive and collect liquids, such as urine or menstruation and is formed by a permeable material. In addition, the topsheets can also work to help isolate the user's skin from fluids trapped in the absorbent core 16. The topsheets can be formed by a single layer or by several layers, and these layers can be formed by similar materials or many different. The topsheets are known in the art and can be manufactured from a wide variety of materials such as, for example, porous foams, reticulated foams, open plastic films, fabric materials, nonwoven fabric webs, sheets and nonwoven webs open fabric. It is also known that one or more chemical treatments can be applied to the materials of the topsheet in order to improve the movement of the liquid through the topsheet and into the article. Suitable topsheets include, without limitation, those described in US4397644 for Matthews and others; US4629643 for Curro et al .; US5188625 Van Iten and others; 5,382,400 to Pike and others; US5533991 to Kirby and others; and 6,410,823 for Daley et al.
    [024] Between the permeable topsheet 12 and the impermeable backsheet 14 an absorbent core 16 is positioned. The absorbent core 16 works to absorb and, preferably, "trap" body fluids that pass to the absorbent article 10 through the topsheet 12. The absorbent core can be formed by a single layer or by several layers, and these layers can be formed by similar or different materials. In order to use the absorbent capacity of the article effectively and efficiently, it is common for the absorbent core to include one or more layers of liquid distribution or layers of capillarity absorption in combination with a highly absorbent layer that preferably absorbs and retains the liquid. Appropriate capillarity absorption layers include, without limitation, carding blankets, hydro-wrapped nonwoven blankets or heat-sealed filament blankets containing treated fibers or containing one or more topical agents that improve the angle of contact with body fluid and / or modify the flow properties of body fluid. Highly absorbent layers often include, without limitation, blankets containing wood pulp fibers, superabsorbent particles, synthetic wood pulp fibers, synthetic fibers and combinations thereof. The absorbent core can be formed by any number of materials and structures and the specific selection of these elements may vary according to the desired load capacity, flexibility, body fluid to be absorbed and other factors known to the experts. For example, materials and / or structures suitable for the absorbent core include, without limitation, those described in US4610678 for Weisman et al .; US6060636 to Yahiaoui and others; US6610903 for Latimer and others; US20100174260 for Di Luccio and others; and US7358282 to Krueger et al.
    [025] The shape of the absorbent core may vary as desired and may be formed by any of several shapes, generally including, without limitation, triangular, rectangular, canine bone and elliptical shapes. In one embodiment, the absorbent core 16 has a shape that generally corresponds to the total shape of the article 10, so that the absorbent core ends close to the edge seal 18 and the wings 20, 30. The dimensions of the absorbent core can be very similar to those mentioned above in relation to the absorbent article 10; however, it is possible to see that the dimensions of the absorbent core 16, although similar, will often be smaller than those of the total absorbent article 10 in order to be contained therein.
    [026] As previously indicated, the absorbent core 16 is positioned between the top sheet 12 and the back sheet 14. The individual layers that form the article can be joined by means known in the art, such as adhesive, heat / pressure bonding, ultrasonic bonding and other appropriate mechanical means. Among the commercially available building adhesives usable in the current invention include, for example, Rextac adhesives available from Huntsman Polymers of Houston, Tex., In addition to adhesives available from Bostik Findley, Inc., of Wauwatosa, Wis. In one configuration and with reference to FIGURE 1, the absorbent core can be sealed between the top sheet 12 and the back sheet 14 along the perimeter of the absorbent core 16 along the edge seal 18 formed by the application of heat and pressure in order to melting the thermoplastic polymers located on the top sheet 12 and / or on the back sheet 14.
    [027] The wings can be constructed from the materials described above with respect to the top and back sheets. In one configuration, the wings can be formed by extending a layer of material within the top sheet and / or the back sheet. For example, and with reference to FIGURE 1, the wings 20, 30 can be formed by an extension of the top sheet 12 and the back sheet 14 which are welded along the edge seal 18. These wings can be integrally formed with the main part of the absorbent article. Alternatively, the wings can be formed independently and attached separately to an intermediate section of the article. The wings independent of the other components of the absorbent article can be welded or glued with adhesive to a part of the top sheet and / or the back sheet. In addition, as is known in the art, when cutting materials to the desired shape, it is preferable to arrange the components in such a way as to minimize waste. Examples of the processes for making absorbent articles and wings include, without limitation, those described in US4059114 to Richards; US4862574 to Hassim et al. WO1997040804 to Emenaker et al; US5342647 to Heindel et al; US20040040650 for Venturino and others; and US7070672 for Alcantara et al.
    [028] In order to further assist in keeping article 10 in the desired position on underwear, it is possible to apply a clothing sticker (not shown) on the side of the back sheet facing clothing 14. The use of the clothing sticker on backsheet to help fix the position of an absorbent article in clothing is known in the art and there are several patterns of adhesives and peelable strips suitable for use with the current invention. Examples of suitable clothing adhesives, patterns and peelable sheets include, without limitation, those described in DE700225U1; US3881490 for Whitehead and others; US 3,913,580 Ginocchio; US 4337772 to Roeder and others; GB1349962 Roeder; US4556146 to Swanson and others; and US20070073255A1 for Thomas et al.
    [029] The absorbent articles of the current invention may also include one or more components or elements, as desired. For example, the absorbent article may optionally include grooves, voids or highlights in the top sheet and / or in the absorbent core in order to improve fluid entry, fluid distribution, stiffness (resistance to bending) and / or appeal aesthetic. A specific example, and with respect to FIGURES 1 and 6, the enhancement 17 can extend up to the top sheet 12 and the absorbent core 16. Among the examples of suitable additional enhancement patterns and methods are, without limitation, those described in US4781710 Megison and others; EP769284A1 for Mizutani and others; US20050182374 for Zander and others; and US7686790 to Rasmussen et al.
    [030] Personal care articles may optionally contain one or more additional elements or components, known and used in the field, including, without limitation, the use of fold lines, individual wraps, elastic flaps that extend above the sheet upper in use, additional independent wings close to the ends, odor control agents, perfumes and use of ink printing on one or more surfaces of the upper sheet, the back sheet, the wings or the absorbent core. Other resources and various constructions are known in the area. Thus, although the invention has been described in detail with respect to specific configurations and / or examples of them, it will be apparent to those skilled in the field that various changes, modifications and other changes can be made to the invention without departing from the spirit and scope of the same . Therefore, it is intended that the claims cover or encompass all such modifications, alterations and / or changes.
