SANITARY TOWEL
Abstract
The invention covers a sanitary article constituted by a slip
inside which is secured an absorbent lining for women's hygienic
and medical purposes, said lining being constituted by superposed
layers of fabric the size of which layers decreases in all
directions from the outermost layer towards the innermost layer,
said fabric being made at least partly of synthetic fibers welded
together at a raised temperature.

Claims
I claim:
1. A sanitary article for women's medical and hygienic purposes
comprising a slip having a crotch and a lining for said slip crotch
including a plurality of superposed interconnected layers of
absorbent fabric the size of said layers in all directions
decreasing stepwise from the outermost towards the innermost layer
whereby the thickness of the lining is greater in its center
registering with all the layers than along its edges corresponding
only to the outermost layer adjacent the slip.
2. A sanitary as claimed in claim 1 wherein the innermost layer of
the lining is provided with a central recess mating the shape of
the wearer's body
3. A sanitary article as claimed in claim 1 wherein the slip is
made of a fabric including at least partly synthetic fibers welded
together at raised temperature
4. A sanitary article as claimed in claim 1 wherein the slip is
made of a fabric including at least partly synthetic fibers welded
together at raised temperature, said article comprising furthermore
a perforated piece of fabric covering the lining facing away from
the slip and welded along its edges to the latter.
Description
The problem of women's periodical hygiene has not yet found a
satisfactory practical solution. The chemist provides in fact his
customers either with an internal plug or with a towel to be used
alone or to be inserted with its fastenings inside a slip.
Internal plugs show a number of drawbacks ascribable to its
insufficient absorbent capacity and to a possible local allergy or
again certain anatomic structures make its use an impossible or
difficult matter.
The use of the towel alone requires special care chiefly by night
with a view to preventing a soiling of the bedding and, if a slip
is used therewith, it is practically impossible for it not to be
soiled and this leads to the necessity of cleaning it frequently.
Furthermore, the towels used nowadays cannot satisfy by reason of
their structure or shape the conditions required for their proper
use.
My invention has for its object to cut out such drawbacks and to
produce a sanitary article of a comparatively low-cost price so
that it may be discarded after use together with the impervious
packing sold for it, which may be of considerable interest chiefly
when travelling.
Said sanitary article is chiefly characterized by the combination
of a slip of a novel structure and design suiting the desired
purpose and incorporating a lining or towel of a preferably special
shape as disclosed hereinafter.
The accompanying drawing illustrates by way of example a preferred
embodiment of a sanitary article according to my invention.
FIG. 1 is a front view thereof
FIGS. 2 and 3 are respectively an elevational and a sectional view
through line III-III of FIG. 2 of the lining before it is
incorporated with the slip.
The slip may be of any type but preferably its shape is that of the
slip sold under the registered trade name Bikini as illustrated at
1. It may be made of ordinary fabric and include an entirely closed
elastic belt or else a belt 2 open on one side or on both sides in
association with fastening means 3. It is however preferable in the
case of my invention to resort to a special textile made of
synthetic or mixed natural and synthetic fibers, said fibers being
assembled through welding at a raised temperature so as to form a
very light and yielding fabric of a reduced cost price showing the
desired properties of resistance, elasticity and imperviousness and
also tolerance by the wearer's skin.
The lining 4 is according to my invention, constituted as
illustrated in FIG. 3 by a plurality of superposed layers
5,5',5",... made of a fabric of a high absorbent power, preferably
similar to that which has just been described for the slip. There
is thus obtained a succession of superposed interconnected layers
of increasing sizes from the innermost layer to the outermost layer
which is secured to the slip, whereby the lining as a whole is
thicker in its center. The innermost layer 5 is thicker in its
center. The innermost layer 5 is thicker than the others and is
recessed or open in its medial section as shown at 5a so as to mate
the shape of the wearer's body. The lining is secured to the slip
through any suitable means but preferably its innermost layer is
covered by a sheet 6 of fabric perforated in registry with the
recess 5a and fitted tightly over the lining to which it is secured
while it may ensure the rigid connection between the latter and the
slip through welding therewith at raised temperature of the
projecting edges 6a of said sheet which is advantageously made of
the same fabric as that described hereinabove.
