Definitions

  • This invention relates generally to improvements in a disposable absorbent brief intended to be used to receive or tending to receive discharge from the body, and which functions as a disposable diaper, incontinent pad, or the like designed to be worn on the body and having a contractable thigh-encircling portion which conforms to the contours of the body and permits movement of the body while maintaining a seal with the body in motion.
  • This invention further relates to means to secure such a brief to the body of the wearer and more particularly to means adapting the thigh-encircling portions of said garment to an adult leg configuration.
  • Absorptive devices such as disposable incontinent briefs are well-known in the art. These devices are used to absorb liquid from the human body and retain that liquid until the garment can be disposed of.
  • Present disposable incontinent briefs are frequently flat composite sheets which are fitted to a wearer in the flat state or incorporate geometric folding to achieve a suitable body shape.
  • a major in-use problem with such prior art articles is that gaps between the brief and the wearer's legs tend to develop due to the semi-rigid nature of the absorbent body, especially after the brief has been worn for some time, or during a period of activity when the garment is able to flex or shift on the wearer's body. These gaps permit leakage from a disposable garment, thereby creating damp outer clothing or bedding around the wearer.
  • a circle drawn at the edge of the garment about the wearer's thigh and substantially perpendicular to the wearer's thigh as defined hereinafter does not at any point approach a second circle drawn around the top portion of the garment secured about the wearer's waist or trunk.
  • a single securement means on each side of the article will not serve to conform the garment to an adult wearer's waist while effectively securing the garment against leakage at the thigh area.
  • an incontinent brief with elastics which are parallel to each other, and which lie along each edge of the crotch. This simplifies the manufacture of an incontinent brief, since the elastic can be applied in the machine direction when the article is manufactured.
  • Brief elastics having a substantially straight-line contractable dimension have advantages in use as well.
  • a substantially straight-line elastic member in the region of the crotch allows a single article to contract substantially along this dimension, so that the differing crotches of various individuals are accommodated to provide a snug fit of the article in the crotch area of the wearer.
  • devices can be found in the prior art which have straight-line elastic members on either side of the crotch; prior art structures having roughly the same can be found wherein a plurality of fasteners are used on either side of a garment to attach it to the body of a wearer.
  • prior art is not available to solve the specific problems which are encountered when straight-line elastic members are used in a garment which requires a plurality of fastening means on either side of the body of the wearer in order to seal the garment to the thigh while providing a fit to the trunk of the wearer as well.
  • the present invention lies in the provision of an improved thigh seal in a disposable absorbent brief particularly adapted to an adult wearer, as defined hereinafter, and having substantially straight-line elastic portions in the crotch area thereof.
  • This seal which is not elasticized around its entire perimeter when the brief is in use, is facilitated by placement of the anchored portion of a thigh securement means on an anchoring region of the brief surface located intermediate two line segments lying respectively on the transversely outward legs of two angles having their apexes at one functional endpoint of the brief elastic, the first angle being about 90 degrees transversely outward with respect to the elastic member, and the second angle being about 140 degrees transversely outward with respect to the same elastic member, said anchoring portion of the brief surface being bordered on its third side by the edge of the brief at a lower part of the trunk-encircling portion.
  • the user-actuated portion of a securement means which is already anchored on the anchoring portion as above defined is further secured to the lower part of the second trunk-encircling portion of the brief in a position effective to achieve the desired seal.
  • the site of attachment of the user-actuated portion of the lower securement means is somewhere on the backsheet of the second trunk-encircling portion, the exact site depending on the particular thigh, trunk, and crotch dimensions of the wearer.
  • a seal is generally defined by the following structures: the elastic member; a portion of the brief material lying along a tensioned line between the functional endpoint of the elastic member which defines the apexes described above and the anchored portion of the thigh securement means; and the user-actuated portion of the thigh securement means. If the user-actuated portion of the thigh securement means is attached to the brief transversely outward of the elastic member, the portion of brief material between that point of attachment and the second functional end of the elastic forms a portion of the seal as well. It is of the essence in this invention that the elements of the seal defined above lie substantially in a plane perpendicular, as defined hereinafter, to the thigh bone of the wearer when the brief is in use.
  • the objects of this invention are to solve the problems noted in the prior art, as well as to provide an incontinent brief with an improved thigh seal, suitable for use by adults and capable of being worn under the clothing of an adult as well as by an adult who is bed-ridden. Further objects of the invention will become apparent from the description following.
  • an “adult” is defined as any person having thigh bones which are oriented substantially parallel to the lateral line of the body during a majority of the wearer's activities. This distinguishes an “adult” from an infant, and particularly from an infant who has not yet learned to walk, for the legs of such an infant usually form a substantial angle with respect to the lateral line of its body during a majority of the wearer's activities.
  • an “adult” as defined herein may include youths and teenagers who have leg orientations similar to those of a mature person.
  • a plane which is "substantially perpendicular" to the thigh-bone of the wearer is defined herein as a plane forming a plane angle of between about 0 degrees and about 40 degrees with respect to a plane which is geometrically perpendicular to the thigh-bone of the wearer.
  • Figures 1 and 2 represent a particularly preferred embodiment of the present invention having side notches which receive the legs of the wearer in order to provide a brief having a well-tailored contour when it is worn.
  • the absorbent brief forming the present invention is comprised generally of moisture-impervious backsheet 1, moisture-pervious topsheet 2, and moisture-absorbent member 3 therebetween.
  • the backsheet 1 and topsheet 2 are preferably secured to one another about absorbent member 3 at the periphery of the article which is generally indicated by 9.
  • the dimensions of the brief of Figure 1 are more particularly described by a longitudinal dimension 4, a transverse dimension 5, a crotch portion 8 having a crotch length 22, a crotch width 21, a cut-out width 20, and trunk-encircling portions 7 and 27. It is to be understood that the brief may be worn with either trunk-encircling portion 7 or trunk-encircling portion 27 forward, although in the preferred mode of use the trunk-encircling portion 7 forms the rear portion of the garment when it is worn.
  • Crotch portion 8 of the article is provided with a plurality of elastic members 10 preferably one on each side of the wearer's crotch, and generally disposed near the edge of the garment.
  • Each elastic member 10 has endpoints 11 and 12, hereinafter referred to as "functional endpoints" because it is appreciated that an end portion of elastic member 10 may be provided which is unable to gather or shirr the garment because it is either stiffened or unadhered to the article.
  • Absorbent member 3 of the brief can be made of any of the absorbent materials known to those of ordinary skill in the bandage art. For example: a multiplicity of plies of creped cellulose wadding; fluffed cellulosic fibers or air- laid wood pulp fibers sometimes known as air- felt fibers or other absorbent material.
  • a particularly preferred absorbent member 3 may be constructed following the teachings of U.S. Patent 3,860,003. While in the embodiment of Figure 1 absorbent member 3 lies generally between elastic members 10 in the crotch portion of the brief it is to be appreciated that this is not a requirement of the present invention, so long as elastic members 10 are able to contract the brief.
  • Moisture-impervious backsheet 1 is preferably a flexible moisture-impermeable sheet comprised of a low density, opaque polyethylene web having a thickness of about 0.025 mm, such as the backsheet employed in the aforementioned USP 3860003.
  • the backsheet 1 has a rectangular configuration with leg cut-out areas 19 deviating from the rectangular configuration.
  • the backsheet 1 extends beyond the periphery of the absorbent body around the entire periphery thereof.
  • Brief side portion 9 defined generally by the periphery of the backsheet extending beyond absorbent member 3, is roughtly 100 mm wide in the trunk-encircling portions 7 and 27 and approximately 37.5 mm to 50 mm wide in the crotch portion 8 of the brief.
  • Topsheet 2 is coextensive in area with backsheet 1.
  • One preferred embodiment of topsheet 2 is shown and described in U.S. Patent 3,929,135 issued to Hugh Thompson on December 30, 1975. However, it is to be understood that the invention does not require a particular type of topsheet, or any topsheet at all.
  • the elastic member 10 is operatively associated with crotch portion 8 adjacent to brief side portion 9 in an elastically contractable condition so that in a normally unrestrained configuration, the elastic member 10 effectively contracts or gathers the crotch material to provide an elastic retraction line 13 colinear with the material of elastic member 10. Attachment of the elastic members 10 to achieve this result is also described in the aforementioned USP 3860003.
  • FIG. 1 A comparison between Figures 1 and 2 will illustrate the function of the elastic members 10 on either side of the crotch to adjust the length of the crotch to fit the body of a wearer.
  • crotch portion 8 has a maximized crotch length dimension 22.
  • the crotch length dimension 22' is roughly one-half as large as the identical dimension in Figure 1. The exact variance between the dimensions 22 and 22' will depend on how the side-notch and crotch are dimensioned in a particular garment.
  • the material in the crotch is gathered in Figure 2, but the width 21 of the crotch is substantially unchanged between the two Figures. It has been found that when the crotch is elastically contractable in the longitudinal direction without substantial transverse contraction, the brief is well-suited to accommodate a wide range of sizes without the need for measurements or mechanical adjustments.
  • the effective length of elastic member 10 in its stretched condition is that length available to contract.
  • the extremities of this effective length of elastic are defined by functional endpoints 11 and 12. These functional endpoints 11 and 12 may be distinguished from the actual endpoints of the elastic, for it is apparent that portions of the elastic may be so secured to the brief that they are unable to contract, or loose ends of the elastic may be allowed which do not contribute to the contraction of the brief.
  • Upper securement means 14 may be provided by any of a number of means well-known in the art, such as tapes, an elastic band to which both ends of the brief are attached (analogous to the waistband of conventional underwear), snaps, pins, and so forth.
  • lower securement means 15 can be any securement means which can be used to attach two portions of the garment together while it is being worn.
  • One particularly preferred fastening means is the tape fastening structure generally disclosed in U.S. Patent 3,848,594 issued to Buell on November 19, 1974.
  • Lower securement means 15 is anchored by a manufacturer's joint at its anchored portion 25 to the brief within anchoring region 16, which is defined by the edge portion of the brief 9 and by line segments 17 and 18.
  • First line segment 17 is bounded at its transversely inward end by functional endpoint 11 of the elastic member 10, and extends transversely outward from functional endpoint 11 in the plane of the brief at an angle a with respect to elastic member 10.
  • Second line segment 18 similarly is bounded by functional endpoint 11 and extends transversely outward to the edge portion 9 of the brief in the plane of the brief at an angle fJ with respect to elastic member 10.
  • the angle a is preferably about 90 degrees, and the angle fJ is preferably about 140 degrees when the elastics are located within 37.5 mm of the lateral edge of the crotch portion of the diaper along a majority of their length. Particularly preferred values of a and fJ are about 116 degrees and about 125 degrees, respectively.
  • a tension vector defines a portion of the brief between lower securement means 15 and functional endpoint 11 which lies approximately in a plane which is substantially perpendicular to the thigh of the wearer when the brief is worn, forming a part of the thigh seal.
  • upper securement means 14 is brought laterally around the trunk of the wearer and secured to the other side of the brief somewhere along the upper part of trunk-encircling portion 27.
  • lower securement means 15 is secured to the lower part of trunk-encircling portion 27.
  • elastic member 10 lies along the inner portion of the thigh of the wearer, and securement vector 24 lies along a second portion of the wearer's thigh. If the point of attachment of the user-actuated portion 26 of lower securement means 15 on trunk-encircling portion 27 is transversely inward of the line defined by elastic member 10, securement vector 24 overlies that line and is held in that overlying relation by circumferential tension to complete the seal. On the other hand, if the point of attachment of the user-actuated portion 26 of lower securement means 15 is transversely outward of a line defined by elastic member 10, the material of the garment spanning the space between said point of attachment and functional endpoint 12 of elastic member 10 completes the seal.
  • this structure satisfies the objects of this invention to provide a thigh seal which lies approximately in a plane which is substantially perpendicular to the thigh-bone of the wearer.
  • a medium-sized brief adapted to fit the ordinary range of adult wearers having hip circumferential measurements in the range of 813 mm-1118 mm can be accommodated by a brief having a functional stretched elastic length of 203-229 mm, a longitudinal dimension 4 of approximately 838 mm, a transverse dimension 5 of approximately 635 mm, a crotch width 21 of approximately 241 mm, and spacing between elastic members 10 across the crotch of approximately 203 mm.
  • a brief may conveniently be dimensioned with a functional stretched elastic length of 203-229 mm, a longitudinal dimension 4 of approximately 711 mm, a transverse dimension 5 of approximately 457 mm, a crotch width 21 of approximately 178 mm, and spacing between elastic members 10 of approximately 178 mm, and spacing between elastic members 10 of approximately 152 mm across the crotch.
  • a brief for large adults may conveniently have the following dimensions: a functional stretched elastic length of 203-229 mm, a longitudinal dimension 4 of approximately 1016 mm, a transverse dimension 5 of approximately 787 mm, a crotch width 21 of approximately 241 mm, and a spacing between elastic members 10 of approximately 203 mm. While it is to be appreciated that the invention is not limited to embodiments having these dimensions, it has been found that these three brief sizes will accommodate a selection of wearers ranging from adolescents to rather large adults.
  • the optimum angle of the plane of the seal with respect to a plane perpendicular to the thigh of the wearer is an accommodation between the frequently conflicting goals of providing an effective thigh seal and providing a desirable overall fit of the brief to the wearer's body.
  • the ideal angle from a sealing standpoint is nearly 0 degrees, at which point the circumference of the seal is minimized.
  • the ideal angle from a fit standpoint would be much larger for many persons to form an ideal brief-shaped garment.
  • the angles encompassed by the definition of "substantially perpendicular" in this specification represent the middle ground of configurations which will seal adequately while providing an acceptable fit.
  • Figure 3 shows an alternate, but less preferred embodiment of the invention wherein cut-out 19 is attenuated or eliminated from the brief. It will be appreciated that this embodiment will only work if portions of the brief material transversely outward of elastic member 10 will gather in response to retraction of elastic members 10 along elastic retraction lines 13 and will fold when the brief is worn so that the seal as described for the preferred embodiment of the invention will not be hindered by the presence of this material. It will further be appreciated that the general overall shape of the brief may be modified substantially in other ways from the preferred embodiment without departing from the scope of the invention, which is defined by the claims.
  • the most preferred values of a and 13 for this embodiment are about 125 degrees and about 132 degrees, respectively when the elastics are located within approximately 216 mm of the lateral edge of the crotch portion of the diaper along a majority of their length. As this distance is decreased, the included angle a) generally increases.
