Claims
I claim:
1. A panty-designed diaper cover comprising a one-piece outer layer
of water repellent cloth consisting of a waist portion and a crotch
portion with oppositely disposed leg cutout portions at opposite
sides thereof, an inner layer of water repellent material of
similar size and shape to said outer layer, and an intermediate
layer of material of the same size and shape as said outer and
inner layers characterized by the fact that it is permanently
water-resistant, said three layers being stitched together only at
the marginal edges of the waist portions and their opposite side
leg cutout portions so that the crotch portions are substantially
free of needle holes to prevent the seeping of wetness which would
otherwise seep through these needle holes, said intermediate layer
being a fast drying material.
2. A diaper cover as claimed in claim 1, wherein the fast drying
intermediate layer is in contact with said inner and outer layers
throughout their entire surface area so that the inner and outer
layers will tend to dry rapidly.
3. A panty-designed diaper cover comprising a one-piece outer layer
of water repellent cloth consisting of a waist portion and a crotch
portion with oppositely disposed leg cutout portions at opposite
sides thereof, an inner layer of water-repellent material of
similar size and shape to said outer layer, and an intermediate
layer of material of the same size and shape as said outer and
inner layers characterized by the fact that it is permanently
water-resistant, said three layers being stitched together only at
the marginal edges of the waist portions and their opposite side
leg cutout portions so that the crotch portions are substantially
free of needle holes to prevent the seeping of wetness which would
otherwise seep through these needle holes, said intermediate layer
being made from spun-bonded polyester fabric.
Description
The present invention relates to a panty-designed diaper cover and
is an improvement over my U.S. Pat. No. 2,695,615 granted Nov. 30,
1954 for an infant's garment.
An object of this improvement is to combine with an inner and outer
layer of water repellent stretchable material an intermediate layer
of material which is water-resistant at all times, nonstretchable,
nonshrinkable and has quick drying characteristics, such as
spun-bonded polyester fiber.
Another object of the present invention is to provide an article of
this kind in which the three layers are of the same size and shape
and in which the intermediate layer is in contact with the entire
surface areas of the other two layers so that by virtue of its
quick drying characteristic the intermediate layer will accelerate
the drying time of the other two layers.
The present invention aims to provide a garment of this type in
which the three layers are secured together by a minimum of
stitches so that the crotch area of the garment will be
substantially free of needle holes to present in the crotch area a
minimum of such holes through which wetness could seep to the
child's outer garments.
A further aim of this invention is to provide a garment of this
character which is considerably lighter than the conventional
garment of this kind and in which the garment can not shrink since
the intermediate layer to which the other layers are secured does
not shrink and stays flat and smooth during use and after
washing.
Other and further objects and advantages of the present invention
will be apparent from the following description thereof:
Referring now to the drawing wherein like numerals refer to the
same or corresponding parts throughout the several views:
FIG. 1 is a perspective view showing the panty-designed diaper
cover embodying the features of the present invention as being worn
by an infant;
FIG. 2 is a plan view of the diaper cover before stitching;
FIG. 3 is a sectional view taken on the line 3-3 of FIG. 2;
FIG. 4 is a rear view of the diaper cover as shown in FIG. 1.
FIG. 5 is a side elevational view of the diaper cover shown in FIG.
4.
FIG. 6 is a sectional view taken on the line 6-6 of FIG. 4.
Referring now to the drawing, and more particularly to FIGS. 2 and
3, the panty-designed diaper cover embodying the features of the
present invention includes an outer layer of water-repellent
material, such as knit cotton, indicated by the numeral 20, an
intermediate layer of nonstretchable, nonshrinkable,
water-resistant and fast drying material, such as spun-bonded
polyester fiber, indicated by the numeral 21, and an inner layer of
water-repellent material, such as knit cotton, indicated by the
numeral 22. Each of the three layers is of the same size and shape
so that the intermediate layer is coextensive and in intimate
contact with the entire surface areas of the inner and outer
layers. Since the intermediate layer 21 is nonstretchable,
nonshrinkable and fast drying its contact with the inner and outer
layers of the cover will accelerate the drying of the inner and
outer layers and assist in keeping the child's outer garments
dry.
As shown in FIG. 2, each crotch portion of the diaper cover is
similar in size and shape and comprises a narrow central crotch
area 23 and front and rear wide crotch areas 24 and 25 extending
from the area 23. It is to be understood that each of the crotch
portions of the layers 20, 21 and 22 are preferably similar in size
and shape, and each is provided with leg cutout portions 26 and 27
on opposite sides thereof to provide openings for the infant's legs
when the garment is in use, as shown in FIG. 1 of the drawing.
In the assembly of the garment the three layers 20, 21 and 22 are
folded over upon themselves and the leg portions 26 and 27 are
stitched together as at 28 to form the leg openings. The marginal
end portions remote from the crotch areas 23, 24 and 25 are
stitched together as at 29. Likewise the marginal side portions
remote from the crotch areas 23, 24 and 25 are stitched together as
at 30. It will be noted that only a small amount of the stitches 28
border on the crotch area 23 while the crotch areas 24 and 25 are
free of stitches so that there are no needle holes in the crotch
areas 24 and 25 so that no needle holes are formed in these crotch
areas through which wetness could seep to wet the infant's outer
garments. Also in the central crotch area 23 a minimum of needle
holes are formed so that an inconsequential amount of wetness can
seep through the small number of needle holes in the small part of
the central crotch 23.
The numeral 31 generally refers to the waist area of the garment
and there may be provided a conventional elastic waistband which
may be suitably sewn into the waist area 31. Shirt attaching tabs
32 of any conventional form are secured to the side portions of the
garment for securing the garment to a shirt 33 of the infant by
safety pins or other conventional means not shown.
Attention is directed to the fact that an important feature of the
present invention is the employment of spun-bonded polyester fabric
as the intermediate layer and making the intermediate layer the
same size and shape as the inner and outer layers so that the great
majority of the stitches and needle holes are formed along the
marginal edges of the layers remote from the crotch areas.
Accordingly it has been found that this spun-bonded polyester
fabric as the intermediate layer is a tremendous improvement over
the flannelette and other conventional linings previously used
because:
1. It remains water-resistant at all times, whereas the
water-repellency of the flannelette is destroyed after a few
washings.
2. This material dries exceptionally fast so that the outer layers
of the garment tend to dry fast also, as they are in contact with
it. On the other hand, the flannelette takes a long time to dry and
seems to keep the outer layers damp.
3. This spun-bonded polyester fabric is lighter in weight than the
flannelette; does not shrink like flannelette and stays flat and
smooth after washing, unlike flannelette.
4. By designing the garment in this new manner there is no need to
sew on a separate crotch portion, thus eliminating the needle holes
which could cause some wetness to seep through the water-repellent
fabric. But, in the new design there are no needle holes in the
crotch area, where most of the wetness of the baby's diaper is
concentrated and therefore this improved garment now performs
better than ever.
Also the purpose of the spun-bonded polyester fabric since it is
nonstretchable is to hold the inner and outer layers of knit goods
in tight position to prevent the small openings in the knit goods
from stretching and enlarging to such an extent that some wetness
would seep through. Moreover, since the intermediate layer is
coextensive with the other layers and is water repellent, it will
repel the full strength of the baby's urine to preclude the urine
from travelling not only beyond the crotch areas but also
throughout the entire area of the garment.
Another important feature of the present invention is the
employment of the intermediate nonstretchable layer which is sewn
into the leg openings of the baby' s pants in such a manner that it
will prevent the leg openings from stretching completely out of fit
or out of shape after the baby's pants have been washed a few
times. All knit garments are subject to easily stretching after
washing which is not so with the pants of the present
invention.
