Description
This invention relates to a cleansing article and more particularly
to a versatile scouring pad.
In the past, various types of scouring pads have been produced.
Basically steel wool has been used to provide a strong abrasive
scouring pad while certain plastics, with and without coatings
thereon, have been used to provide a mild abrasive surface for
other types of scouring.
The present invention provides a versatile dual-purpose scouring
pad capable of performing both the functions of a strong abrasive
scouring pad and a mild abrasive scouring pad, while also
permitting the insertion of soap or detergent or other suitable
wetting agent into the pad in a manner where the pad itself will
facilitate the digestion of the wetting agent so that the pad may
be conveniently used with optimum effect.
It is a further object of the invention to provide a pillow-shaped
scouring pad which may be reversed so as to bring either a strong
abrasive surface or a mild abrasive surface on the outside of the
scouring pad, and which may be worn as a mitten, and which may
conveniently receive therein various types of wetting agents in the
form of pieces of soap, soap or detergent powder, or the like.
A further object of the invention resides in the provision of a
versatile cleansing article made of any convenient substrate
material, including a cellulosic material, such as paper or cotton,
wool, or the like, or which may be made from a metallic material
such as foil, or which may be made of synthetic materials e.g.
nylon, polyester, polyolefins or the like, and which can be the
product of weaving, knitting, extrusion, wet and dry nonwoven
processes such as felting or the like.
The rough abrasive material may be provided by a coating of a
strongly abrasive very hard material such as carborundum, boron
nitride, silex, nutshells and the like and the mild abrasive
surface may be provided by a coating of melamine, nylon,
polypropylene, jeweler's rouge or the like, or may be the surface
of the substrate material.
It is yet another object of the invention to provide a versatile
scouring pad having two substrate layers formed in the shape of a
pillow and in which two or more pairs of abutting edges can be heat
sealed or otherwise bonded together by adhesives, solvents, or the
like, or else stitched together.
An additional object of the invention resides in the provision of a
pillow-shaped scouring pad that allows for the insertion of soap
scraps, dishcloths, sponges or the like for further assisting the
abrasive surface thereof with detergency, absorbency, bulk or the
like in its cleansing operations and which may be worn as a mitten
on the hand if so desired.
These, together with the various ancillary objects and features of
this invention, which will become apparent as the following
description proceeds, are attained by this reversible scouring pad,
preferred embodiments of which are illustrated in the accompanying
drawing, by way of example only, wherein:
FIG. 1 is a perspective view of a pillow-shaped scouring pad
constructed in accordance with the concepts of the present
invention;
FIG. 2 is a longitudinal sectional view of the scouring pad;
FIG. 3 is an end elevational view of the scouring pad in a reduced
scale;
FIG. 4 is a transverse sectional view of the scouring pad showing
the coating on the substrate material;
FIG. 5 is a sectional detail view illustrating one form of opening
for the form of scouring pad which is sealed on three sides;
FIG. 6 is a horizontal sectional view taken along the plane of line
6-6 in FIG. 3;
FIG. 7 is a longitudinal sectional detail view similar to FIG. 2,
but showing the scouring pad as reversed; and,
FIG. 8 is a longitudinal sectional view of a modified form of the
invention which is sealed on two sides and open at each end.
With continuing reference to the accompanying drawing, wherein like
reference numerals designate similar parts throughout the various
views and with initial attention to the examples shown in FIGS. 1
through 7, reference numeral 10 generally designates the cleansing
article constructed in accordance with the concept of the present
invention. This cleansing article includes a pair of substrate
layers 12 and 14 which have their side edges 16 and 18, and 20 and
22, as well as their rear edges 24 and 26 secured together by any
suitable means such as heat sealing, dielectric sealing, bonding
using adhesives, solvents and the like, or by stitching as may be
desired. The substrate layers 12 and 14 can be formed of the same
material or different material, and can be made of nylon,
polyester, or the like, or can be formed from materials such as
paper, cotton, wool, metallic wool or foil or any suitable
synthetic plastic material by weaving, knitting, extrusion,
felting, or wet or dry nonwoven processes. The open end of the pad
10 may have the edges 28 and 30 of the substrate material contoured
as desired and they may be elasticized, scoured, or decorated in
any manner.
In accordance with the preferred concept of the present invention,
the substrate layers 12 and 14 have coatings of abrasive materials
thereon. The layers 12 and 14 have coatings 32 and 34 of a strongly
abrasive, very hard material such as carborundum, boron nitride,
silex, nutshells or the like, while coatings 36 and 38 are provided
for the substrate layers 12 and 14 and are formed of melamine
resin, nylon, polypropylene, jeweler's rouge, or the like, to form
a milder abrasive surface. The coatings 32 and 34 are similar to
each other and remote from each other, while the coatings 36 and 38
are adjacent each other so that the entire pad provides a rough
abrasive surface for the entire pad in the position as shown in
FIG. 2, while when the pad is reversed to the position as shown in
FIG. 7, an entire pad having a milder abrasive surface is
provided.
It is to be recognized that by making the edges 28 and 32
elasticized, the reversing of the pad is facilitated. The pad may
be worn like a mitten and the pillow gives two surfaces which can
do two separate jobs, while also allowing for the insertion of soap
scraps, soap or detergent powders, dishcloths, sponges, and the
like to further assist the abrasive surface with detergency,
absorbency, bulk, and the like.
In FIG. 8, there is shown a modified form of the invention where in
lieu of the rear edges 24 and 26 being sealed together, they may be
left open and as shown at 24a and 26a, they may be decorated,
elasticized, scored, or otherwise left open so that a pad open at
both ends is achieved.
It is to be recognized that all of the coatings may be the same and
alternatively, the one substrate layer may be entirely coated with
one material, while the other substrate layer may be coated with a
different material, or the substrate layers themselves may be
formed of an abrasive material.
When inserting soap pieces or the like in the pillow 10, the
abrasive surface is contacting the soap pieces and digest the soap
pieces by causing them to break and become comminuted thereby
facilitating the passing into solution with water or the like of
the soap pieces.
A latitude of modification, substitution, and change is intended in
the foregoing disclosure, and in some instances, some features of
the invention will be employed without a corresponding use of other
features. Accordingly, it is appropriate that the appended claims
be construed broadly and in a manner consistent with the spirit and
scope of the invention herein.
