CHILD'S ENURESIS UNDERGARMENT
Background of the Invention
Field of the Invention
The present invention relates to children's undergarments, for
example, a girl's panty or a boy's brief, and more particularly, to such
undergarments having a feature or features on the body-facing side of the
undergarment which assist in collecting and/or absorbing urinary voids.
Description of The Related Art
Many children throughout the world suffer from a form of urinary
incontinence known as enuresis, which refers to the involuntary discharge of urine
after the age by which a child's bladder control should have been established. Most
typically, a child develops voluntary control of urination by the age of five.
However, there is a substantial population for which this is not the case. For
example, nocturnal enuresis, typically referred to as "bed wetting", generally is
present in about ten percent of otherwise healthy five-year-old children, and in
about one percent of otherwise healthy children at age fifteen. Tabor 's Cyclopedic
Medical Dictionary, Ed. 17, page 653, © 1993 F.A. Davis Co. In fact, in the
United States alone, there are approximately 1.6 billion bed wettings per year.
Moreover, enuresis is not limited to urinary incontinence which occurs during the
night time. Many children experience urinary incontinence during the day, a
condition known as diurnal enuresis. Id. at page 653.
In the vast majority of cases, there is no organic basis for persistent
enuresis. While toilet training may play a role in many cases, emotional stress,
such as the birth of a sibling, a death in the family, or separation from the family,
may be associated with the onset of enuresis in a previously continent child. Id. at
page 653.
Enuresis also may be caused by disease or injury, and depending
upon the particular disease or injury, this urinary incontinence may be a long-term
condition. Some of the conditions that may cause enuresis include urinary tract
infection, increased fluid intake due to diabetes mellitus, any disease that interferes
with the formation of concentrated urine, trauma to or disease of the spinal cord,
and epilepsy. Disease usually also plays a role in the development of day-time
urinary incontinence, with this condition also persisting for long periods of time,
especially after a protracted illness. The day-time discharges themselves may be
caused by muscular contractions brought about by laughing, coughing, or crying.
Id. at page 653.
Beyond the clinical aspects of this form of urinary incontinence, the
condition typically has a significantly negative impact on a child's self-esteem.
And although a loss of self-esteem is undesirable in general, it is particulary
undesirable in childhood, a time which is extremely important in developing a
person's sense of self-confidence and self-esteem. For example, a child may be
embarrassed by his or her lack of bladder control, and therefore, may be reluctant to
participate in a full range of activities, for fear of embarrassment or lack of
acceptance. For example, if the child is a bed wetter, he or she may be reluctant to
go to a slumber party. Alternatively, if the child has day-time incontinence, he or
she may be reluctant to play with friends, or even to attend school.
Given the substantial number of children with enuresis, the sizable
number of involuntary urinary voids experienced by these children, and the
reduction in self-esteem which typically accompanies this condition, it is extremely
important to assist the child in any way possible. One such form of assistance has
been to provide a pad which may be placed in a child's undergarment for receiving
an enuretic void. This pad is quite long so that it may cover the external genitalia
of either a girl or a boy, and the pad is relatively thick as well. These features result
in a pad which is bulky and uncomfortable, and which also has a tendency to move
out of position within the undergarment, thereby reducing, and in some cases
preventing, any benefit, either when used during the nighttime or during the day.
Moreover, because the pad is relatively bulky and slides around, and because the
pad may not effectively capture the void, a child is still likely to soil his or her bed
or clothing.
Summary of the Invention
The present invention overcomes the above-mentioned drawbacks
by providing an undergarment having a free-floating, self-adjusting support inside
the undergarment body. The self-adjusting support includes a front elasticized
panel, a back elasticized panel, and a discharge-receiving panel therebetween, with
the discharge-receiving panel adapted to receive an absorbent pad. The front panel
is connected to the front waist area of the undergarment, and the back panel is
connected to the back waist area, such that the discharge-receiving panel floats
within the undergarment. This design results in a child's undergarment in which
the discharge-receiving panel, and, if desired, a pad received on the discharge-
receiving panel, are positioned in close, confronting relationship with a child's
external genitalia, thereby absorbing and retaining urine from an enuretic void, and
reducing the possibility of urine soiling the undergarment body portion, outer
clothing, and/or bedding. Furthermore, the discharge-receiving panel remains in
close, confronting relationship even when a child is tossing and turning during
sleep, or walking or running about during the day.
In one form of the invention, the discharge-receiving panel of the
self-adjusting support is sized and constructed to receive a conventional absorbent
pad and to keep a large portion of the pad's upper surface exposed. This particular
version of the discharge-receiving panel includes front and back pockets and
longitudinal sidewalls which serve to securely hold the pad, while at the same time
leaving most of the pad's upper surface exposed, so as to be in direct confronting
relationship with a child's external genitalia when the undergarment is worn. In
addition, the longitudinal sidewalls tend to cradle the external genitalia, thereby
further assisting in collecting and retaining urine from an enuretic discharge.
In another aspect of the invention, the length of the front panel may
be different from the length of the back panel, so as to create an undergarment
which is tailored to the particular sex and/or age of the child, thereby enabling the
undergarment to provide optimal urine collection and retention. For example, in a
girl's version of the undergarment, the front and back panels may be substantially
similar in length, thereby centrally locating the discharge-receiving panel and
absorbent pad within the undergarment and directly below the girl's genitalia.
While in a boy's version, the front panel may be substantially shorter than the back
panel, thereby positioning the discharge-receiving panel and pad more toward the
front of the undergarment in confronting relationship with the boy's genitalia.
Because the location of the discharge-receiving panel may be customized and
optimized in this manner, it is possible to produce undergarments in which the
length of the discharge-receiving panel is the same for a boy's version as it is for a
girl's version. It also is possible to produce an undergarment having a relatively
short discharge-receiving panel. These features have important implications for
enhanced comfort and appearance, and for reduced cost. For example, because a
relatively short discharge-receiving panel may be used, a proportionately shorter
pad may be used as well, thereby giving the undergarment a more natural
appearance and more comfortable feel; also, because the shorter discharge-
receiving panel and shorter pad may be made with less material, they cost less to
produce. In addition, because the size of the discharge-receiving panel may be the
same in either a girl's or a boy's version, there is no need to make multiple pad
sizes. Accordingly, a manufacturer may realize lower costs through economies of
scale, and a retailer may preserve precious shelf space by having to stock only a
single pad size.
The undergarment itself may be any undergarment capable of
attachably receiving the self-adjusting support front and back panels and capable of
maintaining the discharge-receiving panel in close, confronting relationship with a
child's external genital area. Advantageously, the undergarment is a boy's brief or
a girl's panty having a traditional exterior appearance, thereby assisting a child in
feeling a relative sense of normalcy. Also, if a pad is used with the discharge-
receiving panel, the pad may be any conventional, relatively thin, disposable or
reusable absorbent pad.
By virtue of the foregoing, there is provided a convenient,
aesthetically pleasing undergarment which is capable of capturing urine
involuntarily discharged by a child, which is easy to make, and which does not
suffer from the drawbacks of the bulky, uncomfortable and shifting pads
traditionally used. For example, the discharge-receiving panel and front and back
elasticized panels of the self-adjusting support are able to maintain a thin, absorbent
pad in close, confronting relationship to a child's external genital area, thereby
effectively absorbing and trapping discharged urine and preventing the body
portion of the undergarment from becoming soiled, even when the child is moving
around, either during the daytime or while asleep at night, ultimately resulting in an
enhancement of the child's self-esteem and self-confidence. These and other
objects and advantages of the present invention shall be made apparent from the
accompanying drawings and description thereof.

Detailed Description of the Drawings
Figs. 1 A and IB illustrate two particular versions of the
undergarment 8 made according to the principles of the invention, namely, a boy's
brief 10 and a girl's panty 12. Each undergarment 8 shown in these Figures
includes a body portion 14 having a front section 16 and a back section 18, a top
waist section 20 including a front waist area 21, a back waist area 22, and a
peripheral waist opening 23, a pair of leg openings 24, and a crotch area 25
extending between the front waist area 21 and the back waist area 22 between the
leg openings 24. In addition, as shown in Fig. 1A, the boy's brief 10 includes a fly
30. If desired, this fly 30 may be a cosmetic, inoperable fly, designed to give the
boy's brief 10 the appearance of being a traditional undergarment. Alternatively,
the boy's brief 10 may be formed with a traditional, operable fly.
With reference to Figs. 1 A-2A, the undergarment 8 further includes
a self-adjusting support 32 inside the undergarment body portion 14. The support
32 has a front elasticized panel 34, a back elasticized panel 36, and a discharge-
receiving panel 37 therebetween, stitched to the panels 34, 36 along stitch lines 38,
and adapted to support a conventional, absorbent pad, such as the thin, flexible,
absorbent pad 52 shown in Fig. 2A. In addition, the front panel 34 is connected to
the front waist area 21, and the back panel 36 is connected to the back waist area
22. Moreover, in this particular version of the invention, the self-adjusting support
32 is connected to the undergarment 8 only at the front and back waist areas 21, 22.
With the exception of these connecting points, the self-adjusting support 32 is
unattached to the undergarment 8, and therefore, is able to float or move about
freely relative to the undergarment, so as to maintain a confronting relationship
with a child's genitalia area 90, 92 (Figs. 3A and 3B).
With reference to Figs. 2A, 3 A, and 3B, the discharge-receiving
panel 37 includes a child-facing surface 54 and a garment-facing surface 56, as well
as a front end 58, a back end 60, a front pocket 46, a back pocket 48, and a pair of
longitudinal sidewalls 40 extending from the front end 58 to the back end 60. The
front pocket 46 and the back pocket 48 have a non-pleated lip 70 finished with an
elasticized material 44. In addition, each of the longitudinal sidewalls 40 has a
leading section 72 and a trailing section 74, each of which is tacked via stitching 50
to a portion of the front and back pocket non-pleated lips 70. Also, each of the
longitudinal sidewalls 40 is slightly pleated (as shown at 42) and finished with an
elasticized material 44.
In this particular version of the undergarment 8, the front and back
pockets 46, 48 and longitudinal sidewalls 40 of the discharge-receiving panel 37
serve to securely hold the pad 52 on the panel 37, while at the same time leaving
most of the pad's upper surface 62 exposed and in direct confronting relationship
with a child's external genital area, as at 90 and 92 in Figs. 3A and 3B,
respectively. In addition, the longitudinal sidewalls 40 tend to hug the portion (not
shown) of the crotch area 25 adjacent each side of the genitalia 90, 92, thereby
further assisting in collecting and retaining urine from an enuretic discharge.
The discharge-receiving panel 37 includes a liquid-resistant
material, with the term "liquid-resistant" referring to the ability of a particular
material or combination of materials to slow, inhibit, or even prevent the
transmission of a liquid through the material or combination of materials. If
desired, depending upon the particular liquid-resistant material employed, the
material may be coated or laminated onto another material. The particular material
or materials selected may advantageously be soft, flexible, and light weight, and
may possess a degree of elastic stretch. By way of example, the liquid-resistant
material may be a vinyl, urethane, or polyethylene, either alone or in combination
with another material. If desired, the discharge-receiving panel 37 may include a
knit, woven, or non- woven fabric on one or both of a body-facing surface 54 (Figs.
3 A and 3B) and a garment-facing surface 56 (Figs. 3 A and 3B) of the panel 37,
thereby improving wash, wear, and/or comfort. In addition, a liquid-resistant, non-
woven fabric may be used, either alone or in combination with other materials, in
forming the discharge-receiving panel 37.
By way of further example, the discharge-receiving panel 37 may be made
of a vinyl/fabric combination in which the vinyl is extruded onto a polyester, all-
directional, stretch-knit fabric- This vinyl/fabric material may be obtained from
Ouimet, 2960 Sidco Drive, Nashville, TN 37204. Alternatively, the discharge-
receiving panel 37 may be made of an embossed vinyl film. If desired, this film
may be made by a casting process, in which the film is placed against a sheet of
casting paper, and the two layers are run over or under an embossing roller, with
the casting paper contacting the embossing roller. In this fashion, the embossing
pattern is transferred through the casting paper to the vinyl film. Then the casting
paper may be removed and discarded, or subsequently reused. Such a vinyl film
also is available from Ouimet, 2960 Sidco Drive, Nashville, TN 37204. Also, the
discharge-receiving panel 37 may be a urethane/fabric combination, in which a
urethane film is laminated to a polyester, all-directional, stretch-knit fabric.
In one particular version of the undergarment, the discharge-
receiving panel 37 is capable of assuming a natural, arcuate, cupping or cradle-like
shape having various dimensions. When in this shape, and not being worn by a
user, the support 37 has a length of about 8 Vi to about 9 inches, as measured along
the elasticized material 44 of the upper, arcuate edge of each longitudinal sidewall
40. Each of the elasticized longitudinal sidewalls 40, which assists in providing the
cradle-like shape, has an upstanding "height" of about XA to about 1 inch. In
addition, the front and back pockets 46, 48 have a depth of about 1 inch, and the
leading and trailing sections 72, 74 of the longitudinal sidewalls 40 are tacked (as at
50) to the front and back pocket lips 70, respectively, about 'Λ to about 1 inch in
(toward the longitudinal centerline of the panel 37) from the sides 80 located at the
front and back ends 58, 60 of the discharge-receiving panel 37. These various
dimensions assist in providing a sidewall-to-sidewall width of from about 2 Vi
inches to about 3 Vi inches. While these dimensions are the dimensions of a
particular version of the panel 37 when the undergarment is not being worn, it
should be understood that, because of the flexible nature of the discharge-receiving
panel 37, the panel 37 is capable of conforming generally to the particular size and
movements of the user.
The discharge-receiving panel 37 may be made by starting with a
substantially rectangular, flat piece of the desired material or materials, with the flat
piece having a length of about 16 inches and a width of about 6 inches. The piece
of material or materials then may be formed into the discharge-receiving panel 37
described in detail above, using traditional textile manufacturing techniques.
For the sake of illustration, Fig. 2A depicts both a boy's version and
a girl's version of the self-adjusting support 32. In particular, the reference lines
labeled B (for boy) illustrate one example of the front and back terminating ends
84, 85 of the front and back elasticized panels 34, 36, for the boy's brief 10. These
ends 84, 85 subsequently are stitched to the front waist area 21 and back waist area
22 of the boy's brief 10, as shown in Figs. 1A and 3A. As shown in Figs. 2A and
3 A, because the boy's brief 10 includes a front panel 34 which is shorter than the
back panel 36, the discharge-receiving panel 37 and absorbent pad 52 are
positioned toward, and, if desired, into, the front waist area 21, so as to be in close,
confronting relationship with a boy's external genital area 90. For example, the
back panel 36 may be at least about twice the length of the front panel 34, and
advantageously, about two to three times the length of the front panel 34. One
particular version of the brief 10 includes a front panel 34 having a length of about
1 14 inches and a back panel 36 having a length of about 4 inches.
Referring back to Fig. 2A, the reference lines indicated by the letter
G (for girl) denote an example of the terminating front and back ends 86, 87 of the
front and back elasticized panels 34, 36 of the self-adjusting support 32 used in the
girl's panty 12 shown in Figs. IB and 3B. These ends 86, 87 then are stitched to
the front waist area 21 and back waist area 22 of the panty 12. As shown in Figs.
2A and 3B, the front panel 34 and back panel 36 may be substantially similar in
length, thereby substantially positioning the discharge-receiving panel 37 and
absorbent pad 52 centrally in the crotch area 25. This positioning keeps the
discharge-receiving panel 37 and pad 52 in close, confronting relationship to the
girl's external genital area 92, thereby providing maximum effectiveness in
absorbing and retaining discharged urine. By way of further example, the back
panel 36 may advantageously have a length which is less than about twice the
length of the front panel 34. One particular version of the panty 12 includes a front
panel 34 length of about 114 inches and a back panel 36 length of about 2 14 inches.
The fabric used for the front and back elasticized panels 34, 36
shown in Figs. 1-3 may be any fabric having some degree of elastic stretch. For
example, the fabric may be a cotton/polyester blend, either with or without Lycra®
spandex. Alternatively, the fabric may be a nylon, a nylon blend, or Lycra®
spandex. The elasticized panel may be a knit, woven, nonwoven, or film, and if a
knit fabric is used, the knit may be, for example, a jersey knit, interlock, or warp
knit. In addition, if yarns are used, the yarns may suitably be filament or spun
yarns. The particular material or materials used may advantageously have both
vertical and horizontal elastic stretch, capable of maximum stretch and recovery.
Also, the material or materials used for the front and back elasticized panels 34, 36
may be water repellant or absorbent, as will be readily understood by one of
ordinary skill in the art. The front and back elasticized panels 34, 36 may be
connected to the discharge-receiving panel 37 and front and back waist areas 24, 26
using any conventional method or methods. For example, the panels 34, 36 may be
sewn, fused or snapped to the panel 37 and waist areas 24, 26.
The body portion 14 of the undergarment may be formed of any
suitable material or combination of materials. However, because one purpose of
the invention is to provide an undergarment which looks and feels as natural and
traditional as possible, the body portion 14 advantageously may be made of a
cotton-rich blend, containing at least about 50 percent cotton, thereby providing the
look and feel of a traditional boy's brief or girl's panty. If desired, the cotton-rich
blend may be formed using a nylon and/or Lycra® spandex. Non-limiting
examples of other suitable materials include any natural or synthetic material, such
as cotton, nylon, polyester, or Lycra® spandex, for example, either as a
homogeneous material or in the form of a blend. In addition, the yarns themselves
may be regular yarns, microdenier yarns, spun yarns, or filament yarns, or various
combinations thereof. And if desired, Lycra® spandex or some other elasticized
material may be incorporated into the fabric used for the undergarment body. The
undergarment body itself may be formed using conventional fabric weaves, knits,
cutting, sewing, and stitching techniques.
In order to achieve the goal of an undergarment having a traditional
appearance, while at the same time absorbing and retaining a urinary discharge, the
absorbent pad may be a conventional thin, soft, flexible pad made of disposable
materials, such as shown in Fig. 2B, so that the pad may be easily removed and
properly discarded after a void or series of voids. One particular version of the pad
may have a length of about 9 inches, a width of about 4 inches, and a thickness of
about 3/8 inch. In addition, the discharge-receiving panel 37 is designed to
accommodate virtually any thin, soft, flexible disposable or reusable pad, either of
which may be made using traditional materials and methods.
In using the undergarment 8 of the present invention, a parent or
child releasably secures a thin, soft absorbent pad 52 on the flexible, thin discharge-
receiving panel 37 which is suspended from the front and back waist areas 21, 22
by the front and back elasticized panels 34, 36. The parent or child then pulls the
peripheral waist opening 23 of the undergarment 8 up around the child's waist.
Because of the design of the discharge-receiving panel 37 and the front and back
elasticized panels 34, 36, the undergarment 8 maintains the absorbent pad 52 and
discharge-receiving panel 37 in close, confronting relationship to the child's
external genital area 90, 92, whether the child is stationary or is actively moving
about, thereby absorbing urine from an enuretic void and preventing the urine from
soiling the body portion 14 of the undergarment 8, as well as outer garments and/or
bedding. In addition, because the self-adjusting support 32 and pad 52 are
relatively thin and flexible, the invention provides a natural-looking undergarment
8 which assists a child in managing urinary incontinence in a way which enhances
the child's self-esteem.
While the present invention has been illustrated by this description
of embodiments, and while the illustrative embodiments have been described in
considerable detail, it is not the intention of the inventor to restrict or in any way
limit the scope of the appended claim to such detail. Additional advantages and
modifications will readily appear to those skilled in the art. For example, the body
portion of the undergarment may be made of a material or blend having a
substantial amount of an elastic material, thereby allowing that particular
undergarment to accommodate children of many different shapes and sizes, while
still maintaining the discharge-receiving panel and pad in close, confronting
relationship to the particular child's external genital area, due, in large part, to the
elastic nature of the front and back panels. The invention, in its broader aspects, is
therefore not limited to the specific details, representative apparatus and methods,
and illustrative examples shown and described- Accordingly, departures may be
made from such details without departing from the spirit and scope of the general
inventive concept.
Having described the invention, what is claimed is:
