Definitions

  • Many absorbent articles intended for personal wear such as diapers, training pants, feminine hygiene products, adult incontinence products, bandages, medical garments and the like are designed to be sufficiently absorbent to pull moisture from liquid body exudates including urine, menses, blood, etc. away from the wearer to reduce skin irritation caused by prolonged exposure to wetness.
  • Diapers as an example, are typically placed and secured on a wearer using a set of primary fastening tabs, such as adhesive tabs or mechanical (e.g., hook or loop) fastening system tabs and left in place to absorb insults as well as to contain fecal waste.
  • Training pants unlike diapers, typically come pre-assembled in a wear configuration to more closely resemble conventional underpants.
  • front and back waist regions of such training pants are typically attached at a seam either permanently or refastenably (such as by a primary fastening system) to define a wear configuration of the pants having a waist opening and leg openings.
  • Such design enables pull-on prefastened garments to allow for self-application and removal.
  • the present disclosure is directed to a pant-like absorbent articles having handles on side panels of the article for ease of removal and donning of the absorbent garment.
  • the article includes a liquid permeable inner surface for facing the wearer, an outer surface for facing away from the wearer, an absorbent body disposed therebetween.
  • the article further includes a front waist region, a back waist region, and a crotch region extending longitudinally between and interconnecting the front and back waist regions.
  • At least one side panel is attached to the front waist region and the back waist region to define a wear configuration of the absorbent article having a waist opening and a leg opening spaced from the waist opening, wherein the at least one side panel extends from the waist opening to the leg opening.
  • Formed within the side panel is at least one handle.

  • the longitudinal axis lies in the plane of the article and is generally parallel to a vertical plane that bisects a standing wearer into left and right body halves when the article is worn.
  • the transverse axis lies in the plane of the article generally perpendicular to the longitudinal axis. The article as illustrated is longer in the longitudinal direction than in the transverse direction.
  • Machine direction refers to the length of a fabric in the direction in which it is produced, as opposed to "cross direction” that refers to the width of a fabric in a direction generally perpendicular to the machine direction.
  • Machine direction assembly refers to a process in which disposable absorbent products are manufactured in an orientation in which the products are connected end-to-end or waist-to-waist, in the longitudinal direction shown by arrow 48 in Figs. 1 and 2, a process utilizing a machine direction assembly entails products traveling through a converting machine parallel to the direction of arrow 48, as opposed to "cross direction assembly” in which the products are connected side-to-side.
  • Meltblown fiber means fibers formed by extruding a molten thermoplastic material through a plurality of fine, usually circular, die capillaries as molten threads or filaments into converging high velocity heated gas (e.g., air) streams that attenuate the filaments of molten thermoplastic material to reduce their diameter, which can be to microfiber diameter. Thereafter, the meltblown fibers are carried by the high velocity gas stream and are deposited on a collecting surface to form a web of randomly dispersed meltblown fibers.
  • heated gas e.g., air

Furthermore, unless otherwise specifically limited, the term “polymer” shall include all possible geometrical configurations of the material. These configurations include, but are not limited to isotactic, syndiotactic and atactic symmetries. "Refastenable” refers to the property of two elements being capable of releasable attachment, separation, and subsequent releasable reattachment without substantial permanent deformation or rupture.
  • Releasably attached refers to two elements being connected or connectable such that the elements tend to remain connected absent a separation force applied to one or both of the elements, and the elements being capable of separation without substantial permanent deformation or rupture. The required separation force is typically beyond that encountered while wearing the absorbent garment. It should be noted that a releasably attached or releasably engaged seam is a refastenable seam that does not include a bonded seam that must be torn, cut, or otherwise disrupted.

  • the handle 90 is formed by cutting an aperture 92 having a longitudinal midpoint 94, a top portion 96 and a bottom portion 98 through the side panel material 35 as illustrated in Figure 4d.
  • the handle 90 must have sufficient strength to enable the user to pull on the training pants 20 without causing too much displacement in the material. If the handle 90 is too weak, the material will stretch too far causing the article to be stuck around the knees or buttocks while being pulled on or not being placed in the correct position such that it is snug against the wearer's body and is improperly positioned to accept waste.
  • the size and location of the handle 90 may also increase the functionality of the handle as it is optimized to enable independence for a toddler who is learning potty training.
  • the width of the aperture 92 measured as the greatest distance as measured in a laid-flat, relaxed condition in the transverse direction 49 prior to use of the product may enable a user, typically a toddler child, the ability to place their fingers and hands through the aperture and pull on the product.
  • the width of the aperture 92 should not be so great so as to allow for too much displacement during donning and cause issues with the article's effectiveness.
  • a user may use less than four fingers to grasp the handle 90, such as only one or two fingers.
  • an optimal width for the aperture 92 may be from about 20 mm and about 50 mm, such as from about 25 to about 40 mm and more desirably about 30 mm.
  • the location of the handle 90 can also be important to its ability to function correctly. Similarly, when handle is disposed longitudinally 49 proximal to the leg edge 70 the handle 90 is difficult for a user to grasp or the pant 20 becomes difficult to guide onto the body. As a result, distance between the handle 90 and the waist edge 70 may be optimized.
  • the handle 90 comprising an aperture 90 with a top edge 100 may disposed on the side panel 35 such that there is between about 10 and about 35 mm, such as from about 15 to about 25 and more desirably about 20 mm, from the top edge 100 to the waist edge 70 of the side panel 35, as measured when the handle is non- extended.
  • the handle 90 comprising a back distal edge may be disposed on the side panel 35 such that the distance between the back distal edge and the effective edge 102 of the side panel is from about 10 mm and about 35 mm, such as from about 15 to about 25 mm and more desirably about 20 mm, as measured when the handle is non-extended.
  • an effective edge 102 of the side panel 35 is the location where the side panel 35 is bonded to the absorbent assembly 32. In cases, where the side panel is integral with the absorbent assembly 32, the effective edge is where the absorbent core is attached to the outer cover 40.
  • the handle 90 may be formed on the side panel 35 at an angle 125 relative to lateral axis 49 of the side panel 35 to increase ease of use and strength. Angled handles can enable controlling and directing stress and strain resulting from donning. One potential benefit of controlling the force concentrations is to insure they do not occur adjacent to the distal ends of refastenable seams and potentially cause the seam to pop open during donning. As illustrated in Figure 4c, the handle 90 may be placed on the side panel 35 at an angle 125 relative to the lateral axis 49 of the side panel 35 to increase ease of use and strength. Desirably, the handle 90 may be have an angle 125 of at least 2.5 degrees, and more desirably at an angle 125 of between about 10 and about 20 degrees relative to the transverse axis 49 of the side panel 35.
  • the aperture 92 may be any shape known to one skilled in the art including an oval, rectangle, triangle, bean or similar shapes. The shape may also correspond to other graphics on the training pants 20 to provide an overall training pants 20 theme.
  • Figures 4a-4e illustrate various examples of the different shapes the handle could form that would allow for a functioning handle.
  • the aperture has a rectangular oval shape having a maximum width.
  • the aperture is placed at an angle relative to the waist edge.
  • Figure 4e illustrates an alternative shape for the aperture illustrating a bean-shaped aperture.
  • the aperture 92 is formed having a top portion 96 and a bottom portion 98.
  • the aperture 92 has a maximum width at the bottom portion 98 of the aperture 92 and the aperture 92 decreases in width from the bottom portion 98 to the top portion 96.

  • the aperture 92 includes a rounded corner at its top edge 104 as a rounded corner will provide less tearing of the training pants 20.
  • the aperture 92 may be a rounded triangle as illustrated in Figure 4d. This shape helps provide the ability to manage greater maximum stress/strain without inhibiting stretch of the handle. This results in a good balance of displacement and strength, even without a reinforcing material.
  • the handle 90 may include a reinforcing material 1 10 operatively joined adjacent and extending laterally from the distal side edges 106 of the aperture 92 as illustrated in the Figures.
  • the reinforcing material 110 may be a separate piece or multiple pieces of material attached to the at least one side panel.
  • the reinforcing material 1 10 may include a portion of the side panel folded over itself. In this embodiment, the reinforcing material may act also as a waistband for the article.

  • the tangent point may be defined by the closest and farthest points on aperture 92 to the effective edge of the side panel relative to the transverse axis 49 that would result in a longitudinal tangent line. Since the stresses on the handle may be greatest at these tangent points, extending the reinforcing material from the aperture 92 at this location may help to provide the ability to manage greater maximum stress/strain without inhibiting stretch of the handle 90.
  • the tangent points on either side edge of the aperture 92 may not be at the same point on the longitudinal axis 48 of the article. This could result in a tangent point defined by a tangent line in the longitudinal direction on one side edge 106 closer to the waist edge 72 of the side panel 35 and a tangent point defined by a tangent line in the longitudinal direction on the other side edge 106 closer to the leg edge 70 of the side panel 35.
  • the reinforcing material 1 10 may extend from both side edges 106 of the aperture 92 at the tangent point that is closer longitudinally to the waist edge 72 of the side panel 35.
