Claims
I claim:
1. A diaper-holder or napkin holder for babies formed of a sheet of
plastic material having on two opposite sides thereof arcuate
leg-receiving cut-outs and on the two other sides generally
straight-edged parallel ends, said two other sides carrying
mutually facing inner pockets suitable for receiving the respective
ends of a diaper-pad, said inner pockets each being formed at least
partially by folding said other two sides along two spaced apart
fold lines substantially parallel to said ends into two folds of
generally flattened S-shape and welding said folds in place, the
welding for said outer fold line extending at least partially along
the median portion thereof so that the thus-obtained welded part
constitutes a supporting means to keep the diaper-pad in place, and
the welding for said inner fold line being along its side regions
to keep the median portion free to receive the diaper-pad.
2. A diaper-holder according to claim 1, wherein the said outer
fold line is welded along its entire length.
3. A diaper-holder according to claim 1 wherein the said inner fold
is welded along all the portions of its length extending on either
side of the area intended to be occupied by the end of the
diaper-pad.
4. A diaper-holder according to claim 1, wherein the sheet of
plastic material is provided on at least one of its straight sides,
in the area included between the outer fold and the adjacent end of
the sheet, with adhesive areas.
5. A diaper-holder according to claim 1, with a baby's diaper-pad
in position in the diaper-holder, wherein the plastic material of
the diaper-holder and the material of the surface of the diaper-pad
that is intended to come in contact with the skin of the baby are
not mutually heat-weldable.
6. A diaper-holder according to claim 1 wherein said folds are
heat-welded in place.
7. A diaper-holder according to claim 1 wherein in said diaper-pad
surface material is non-woven.
Description
The invention relates to materials for bandages, dressings, etc. .
. , which in the present case are more precisely diaper-holders or
napkin-holders for babies.
A diaper-holder or napkin-holder is already known for babies, this
being of the type formed of a sheet of plastics material with areas
cut out in a wide sweep on two opposite sides, the sheet carrying
on each of the two other sides an inner pocket obtained, at least
partly, by folding over the said other sides, these pockets being
suitable for receiving the respective ends of a diaper-pad for
babies. With the said diaper-holder so positioned that the
diaper-pad is arranged between the legs of the baby, the ends (duly
defined by the cut-out areas) of the sheet of plastics material are
composed of kinds of thongs which are run up towards the waistline
around the trunk of the baby and which are knotted, this ensuring
the retention in position of the diaper-pad.
The employment of such a diaper-holder is quite practical because,
in order to put a diaper on the baby, the operation is greatly
simplified.
However, the diaper-holder of the already known type has several
drawbacks.
First of all, it does not allow the use of diaper-pads of the
current size for babies, but requires, the employment of special
diaper-pads which are of a slightly greater length. In fact, it
will be found that the ends of a normal diaper-pad, when the latter
is placed between the legs of the infant, do not reach very high up
the trunk. For this reason, and through the fact that the
diaper-holder in which the diaper-pad is fitted has substantially
the same length as the diaper-pad, the terminal portions of the
said diaper-holder are not located on a level with the waistline,
but lower down. If it is desired to fit the diaper-holder
comfortably around the waist of the infant, it is then necessary to
give it a greater length and, because of this, to employ longer
diaper-pads.
A second drawback arises through the presence of the knots in the
thongs. It is not always very easy to make a knot, especially when
the infant is moving about, and, furthermore, the knots may
constitute annoying lumps of extra thickness.
The invention is aimed more especially at eliminating these two
drawbacks, that is, it makes it possible to employ babies'
diaper-pads of a standard size and it eliminates the need for knots
without producing in practice any often uncomfortable lumps, while
still keeping to a relatively low cost of manufacture.
To this end, according to the invention provision is made, in a
diaper-holder of the type indicated above, for each of the folded
arrangements to be formed of two folds according to a flattened S
shape, that is to say, a first fold at a distance from the central
portion of the diaper-pad, and a second fold somewhat nearer the
said central portion, the folds formed in this way being
heat-welded, the welding being carried out, as regards the first
fold, at least along a median portion of the said first fold which
is located in an area intended to be occupied by one end of the
said first fold which is located in an area intended to be occupied
by one end of the diaper-pad, in such a way that the said welded
part constitutes a supporting means rendering it possible to keep
the diaper-pad in place, and as regards the second fold, solely on
parts of the said second fold that are situated on either side of
the area intended to be occupied by the said end of the
diaper-pad.
Thus, on the sides without the cut-out areas, the sheet of plastics
material forms extensions running on beyond the ends of the
diaper-pad. According to one feature of the invention, at least one
of the said extensions carries adhesive strips.
The following description relating to the accompanying drawing and
given by way of example will indicate how the invention may be
carried into practice.
In the drawings:
FIG. 1 shows, laid flat, in a plan view, a diaper-holder according
to the invention with the baby's diaper-pad in positions;
FIG. 2 is a view of a corresponding longitudinal section, for
example taken along the line II--II in FIG. 1, and
FIG. 3 illustrates the diaper-holder in position on a baby.
In FIG. 1, it will be seen that the diaper-holder is made of a thin
sheet 1 of plastics material such as polyvinyl chloride, a
polyester or another suitable material. This sheet is of a
generally rectangular form which comprises two long sides and two
short sides. The long sides have cut-out areas as shown at 1a, so
as to permit the passing through of the legs and due play around
them. Following the line of its greatest dimension, a bab's
diaper-pad 2 rests against the sheet and is tucked by its ends into
pockets 3, 4 of the sheet which are formed in the manner just
explained. It should be noted that the diaper-pad 2 is formed of an
absorbent cellulose material packet between two sheets 2a, 2b
joined directly at their ends to form tongues 2c which are slipped
into the pockets 3, 4. The sheet 2A is of necessity permeable,
whereas the sheet 2b does not have to be so. For example, the sheet
2a is of a non-woven material, and the sheet 2b is of a cellulose
material. Marks make it possible to distinguish sheet 2b from sheet
2a, so that sheet 2b may be placed against the plastics
material.
In order to form the pockets 3, 4 already mentioned, at 5 and 6
each small side of the sheet of plastic material 1 is folded over
twice to provide the shape of a flattened S, and these folds are
welded into place by heat and pressure, at least fractionally, as
indicated by the arrows. The outer fold 5 may be, and is with
advantage, welded along its entire length, but at least it should
be welded along the portion b--c of the said length that is located
opposite the end of the diaper-pad 2, the said diaper-pad being
thus held in place. The inner fold 6, on the contrary, should not
be welded along the part b'--c' corresponding to the passage-way
for the diaper-pad, but should be welded solely along at least one
part, and with advantage along the entirety, of the portions c'd'
and b'e' which are located on either side of the diaper-pad 2. At
each end the pockets 3, 4 are formed in a similar manner, though it
may be noted that, in the case of the pocket 4, the zone of the
folds falls in an area where material has been cut away, whereas
for the pocket 3 the folds fall outside the cut-away material, so
as to match the anatomy of the body.
Beyond the folds 5 there therefore remain, within the sheet 1,
extensions or flap-ends 1b, 1c (or, to put matters in another way,
the folds have been made relatively far away from the ends of the
sheet so as to provide these extensions) which will constitute a
kind of belt intended to fit around the waist of the baby when
these flap-ends are wrapped around him; the retention in position
of the diaper-holder on the trunk of the baby will then be effected
by an adhesive arrangement, by virtue of two adhesive strips 7, 8
which make the two flaps-ends 1b, 1c to each other. It will be
readily observed from FIG. 3 how the kind of leakproof pants
composed in this manner will then appear.
It should also be pointed out that, among the advantages of the
invention, is the fact that it lends itself well to a mechanized
manufacturing process which includes the automatic cutting out,
folding and welding of the sheets, as well as the automatic
positioning of a diaper-pad 2, to achieve a combined arrangement
"ready to put on the baby." In this respect, it is important that
the non-woven material which constitutes the surface 2a of the
diaper-pad 2 should be carried out in a material which cannot be
heat-welded to the sheet 1 of plastics material. By this means, in
case the means for carrying out heat-welding were to exert their
function in the zone b'--c' , one prevents the diaper-pad 2 itself
from being welded to the diaper-holder. It will then be seen, and
this is also one of the advantages of the invention, that one may
utilize the same diaper-holder several times in succession while
replacing a soiled diaper-pad 2 by a new, clean diaper-pad the ends
of which are tucked into the pockets 3, 4 defined in the manner
described above.
It is self-evident that modifications may be effected in the form
of embodiment just described without however thereby departing form
the scope of the invention as defined by the appended claims.
