Definitions

  • the present invention relates generally to the field of diapers and other wearable absorbent articles having features for the containment and absorption of bodily exudates, and more particularly, to such articles having disposable absorbent inserts and reusable outer covers.
  • Reusable cloth diapers it is likely that reusable diapers made of cloth have been in use since the invention of cloth.
  • Reusable cloth diapers present difficulties relating to sanitation needs, in handling, laundering and effectively sanitizing soiled diapers for re -use.
  • Reusable cloth diapers also may be relatively unreliable with respect to containing bodily exudates (i.e., they may tend to leak). Because a wet cloth diaper may be in direct contact with the skin, unless wetness is quickly detected and the wet diaper removed, it may promote over-hydration of the wearer's skin, which makes the skin vulnerable to diaper rash.
  • a soiled disposable diaper need not be emptied, laundered or handled to any significant extent, but rather, may be discarded as is. Any soiled areas of the wearer's body may then be cleaned, and a clean new disposable diaper may be placed on the wearer as necessary.
  • Many current disposable diapers have structures that make them relatively more effective at containing exudates than traditional cloth diapers. Many have structures and materials that make them relatively more effective at conveying and storing liquid exudates away from the wearer's skin.

  • respective fastening pairs 56, 33 and 57, 32 may include cooperating fastener components.
  • An example of a suitable hook-and-loop fastening system is a VELCRO system, a product of Velcro Industries B.V., components of which are available from Velcro USA, Inc., Manchester, New Hampshire.
  • a hook-and-loop fastening system provides certain advantages.
  • Some types of hook components may, in some circumstances, tend to snag or catch undesirably on a variety of materials in addition to intended corresponding loop components, while most types of loop components currently available do not have this tendency. Thus, in some circumstances it may be desired that patches of loop components form one or both of insert fastener components 33, 32, while patches of hook components form one or both of fastener components 56, 57. This arrangement places a non- snagging insert fastener component on the outer cover. This may be desirable in some circumstances, such as when the outer cover 20 is designed to be reusable - reducing the likelihood that components on an outer cover 20 will undesirably snag on other parts of outer cover 20 or on other articles, such as clothing articles, being stored or laundered along with outer cover 20.
  • an outer cover 20 may have a pocket structure 33a in front region 27 (see Fig. 2C) in combination with a patch of loops component forming rear fastener component 32 (see Fig. 2B).
  • a suitably adapted insert 50 having a patch of hooks as fastener component 57 to install the insert the user may insert the forward edge of insert 50 into the pocket structure 33a, and then fasten the rearward portion of insert 50 into the rear region of the outer cover 20 by engaging respective fastener components 32, 57.
  • An insert fastener component such as component 32 on outer cover 20 may be attached or connected to at least a portion of an anchoring system, such as an anchoring band 38, or diagonal anchoring band 38a. This may provide, as one advantage, the distribution of structural loading resulting from the weight of absorbed or contained exudates, as described in one or more of the patent applications cited above, in the description of anchoring bands.
  • a patch of hook components forming a fastener component 56 and/or 57 attached to insert 50 may be substantially laterally centered on the insert as suggested in the figure, and may have an width W f attached along insert 50 that extends no more than about 50% of the lateral width Wi of the insert 50 at forward region 54 and/or rearward region 55.
  • singularized/localized force-decoupled fastener component pairs 32, 57 may be employed in the 11564-DW 38 rear region 28 of the outer cover 20 and rearward region 55 of the insert 50, while fastener component pairs 33, 56 effectively controlling the forward corners of the insert 50 may be employed in the front region 27 of the outer cover 20 and forward region 54 of the insert 50. This may allow force decoupling of the stretchable outer cover in the back of the article, while maintaining control over the front corners of the insert.
  • fastener components that provide such singularized and relatively laterally localized fastening locations, providing limited force-coupling across the lateral width of at least one end of insert 50, are possible.
  • suitable fastener components may include tab and slot fasteners, macro hook and loop fasteners, button fasteners, interlocking fasteners, hook and slot fasteners, snap fasteners and other fastener types available.
  • insert 50 may sag or buckle, and standing cuffs 53 may be loosened, sag or even collapse. This may lead to gaps between the edges 58 of the cuffs and the wearer's body. In turn, this may compromise the cuffs' gasketing function, and increase the risk of leakage.
  • End support stiffeners 60, 62 may be affixed to, or incorporated within, insert 50 proximate the ends thereof as suggested by Figs. 3 and 4. In addition to increasing the tendency of insert 50 to maintain optimal shape while in use, such end support stiffeners may increase the tendency of the respective ends of insert 50 to stay open and flat before insert 50 is installed in an outer cover. Because the ends of insert 50 may otherwise be folded over or bunched while being stored and/or carried by the user before installation, end support stiffeners may enhance user convenience, by causing the ends of insert 50 to maintain or seek a shape/configuration that requires less manipulation by the user to install it in an outer cover.
  • end support stiffeners may be formed of cardboard or like material.
  • suitable stiffener material is 0.031 in. thick VOLARA foam supplied in sheet form (a product of Sekisui Voltek, LLC, Lawrence, MA). Stiffener materials may be laminated with or adhesively applied to portions of insert 50 to be stiffened, or applied, affixed or included by any other suitable method.
  • suitable stiffening materials may include added layers of nonwovens, tufted nonwovens, films, laminates of films and nonwovens, patches of fastener loops or hooks components, portions of a suitable grasp structure, etc.
  • the portions of the insert including the one or more end support stiffeners 60, 62 are pliable enough to flex comfortably with the wearer's body movements, and to collapse before any form of contusion or impalement injury hazard would be presented. It also may be desirable that stiffened portions are elastic in nature, in they will tend to return to a substantially flat configuration after being bent, folded or twisted.
  • End support stiffeners 60, 62 may increase planar, lateral and/or longitudinal stiffness of the areas of insert 50 in which they are located, as compared with portions of the insert adjacent such stiffeners with respect to a plan view (such as Fig. 4). These differing orientational aspects of stiffness may affect various attributes of the insert. For example, referring to Fig. 3, it can be seen that the ability of a portion including an end support stiffener 60, 62 (stiffened portion) to resist longitudinal tension forces in standing cuffs 53, may be affected by one or more of planar and longitudinal stiffness of the stiffener. The pliability and relative comfort or discomfort for 11564-DW 41 the wearer, associated with a presence of a stiffened portion, may be affected by planar stiffness of the stiffener.
  • Edge Deflection Force is measured according to the Edge Deflection Force Measurement Method set forth below.
