Abstract
The bath scrubber includes an open resilient layer of loops of filaments of flexible, synthetic organic thermoplastic resin a rigid of flexible resin backing and releasable wall mounting means such as mini suction cups. The resin materials can contain antibacterial and antifungal agents.
Description
TECHNICAL FIELD
The present invention relates to a bath accessory, and, more particularly, this invention relates to a bath scrubber that can be used to scrub portions of the body not readily reachable by the hands of the bathers.
BACKGROUND OF THE INVENTION
Scrubbing of the skin during bathing or showering is beneficial to clean the skin, remove dead skin cells, clean the pores and to invigorate the skin and massage underlying muscles and tendons. A widely used natural material known as luffa sponge is used for scrubbing. A luffa sponge can not be used to scrub the back of the bather easily and luffa sponges tend to become fouled with organic skin debris containing bacteria. The luffa sponges are too soft to massage back or shoulder muscles.
Long handled brushes with stiff bristles or luffa sponges mounted in a base, are used for scrubbing the back of bathers. However, the scrubbing action is parallel to the back. It is difficult to apply to the brush or sponge a massaging force perpendicular to the back by manipulating the long handle. Maintaining the fouled bristles or sponge sanitary is again a problem. The ability to manipulate a long-handled scrubber decreases with diminished joint mobility which usually accompanies advancing age. Of course bathers missing hands or arms are not able to manipulate long handled scrubbers.

STATEMENTS OF THE INVENTION
The bath scrubber provided in accordance with the invention, can be used to readily scrub the formerly inaccessible surfaces of the body. The scrubber can be used to apply forces perpendicular to the surface of the body providing action which invigorates the skin and massages muscles, tendons and ligaments under the skin. The scrubber of the invention is not as subject to fouling by bacterial or fungal attack or organic material stuffed from the skin of the user.
The bath scrubber of the invention is formed of a layer of open mat of looped material formed of flexible, synthetic resin filaments attached to a stiff or flexible backing layer. The filaments and/or the backing layer can contain antibacterial and/or antifungal agents. Mounting means, such as suction cups or releasable Velcro straps, are provided on the rear surface of the backing for mounting the scrubber on the wall of a shower or bathtub enclosure. The mounting means are preferably a group of mini suction cups since a single large suction cup will not adhere to a tiled wall when the cup is placed over a grout line.
The bather need not use his/her hands to scrub his/her back. He/she first mounts the scrubber on a wall of a shower or tub enclosure. He/she then applies liquid or solid soap to the mat. He/she then moves backward until his/her back contacts the mat and then moves his/her back in a side to side motion while pressing his/her back against the mat. The loops abrade the skin of the back, removing dead skin cells and clean the pores. The pressure of the resilient loop filament layers invigorates the skin cleans and massages the back.
The scrubber can also be used to scrub the chest or other front portion of the bather. The scrubber is easily repositioned by releasing the suction cups or Velcro strips and repositioning the scrubber at a higher or lower location on the wall or tub. Also the scrubber can be removed from the wall to scrub any portion of body or limbs, feet, etc.
These and many other features and attending advantages of the invention will become apparent, as the invention becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to
FIGS. 1-4
, the bath scrubber
10
of the invention comprises a soft, pliable, yieldable mat layer
12
of serpentine-looped, synthetic resin
14
filaments
13
mounted in a backing
18
. The backing
18
can be rigid such as a panel of plastic or can be a flexible, impervious layer of resin. The loops
14
are flexible and can be arranged in side-by-side rows
30
. The side-by-side loops
14
and rows
30
can overlap. The preferred scrubber, as shown in
FIGS. 5 and 6
, contains a non-woven mat formed of continuous filaments bonded together and embedded in a foam backing to form a durable resilient, water resistant scrubber. When forces normal to the mat are applied, the loops in a row and side-to-side overlap and fold and stack to provide a resilient cushion with the flattened loops providing the desired open, scrubbing action. On release of the pressure, the loops rebound to their original position. The scrubber is readily cleaned by flushing action of a shower head or faucet. The antibacterial and antifungal agents in the filaments and backing, resist fouling of the scrubber.
Referring now to
FIG. 4
, devices such as suction cups
36
for releasably adhering the scrubber to smooth painted or tiled wall surfaces
34
are mounted on the rear surface
32
of the backing
18
. The mounting device can be a strip of hook-loop material such as Velcro which would adhere to a mating Velcro strip adhered to the wall
34
of the enclosure. Suction cups
36
are preferred since they can readily be reattached to the smooth, wet wall surfaces
34
in a bath enclosure or tub
38
. The scrubber
10
is preferably mounted on the wall
34
opposite the wall
42
containing a shower head
44
or bath faucet
46
.
Referring now to
FIGS. 5 and 6
a preferred bath scrubber
100
contains a resilient, open mat layer
112
formed of non-woven continuous filaments
111
which bond together. The mat can be formed by applying a stream of air to molten filaments as they are extruded.
The filaments are preferably formed of vinyl resins. The mat layer can have a thickness of about ¼ inch, a length of about 12 inches and a width of about 8 inches. The mat layer
112
is attached to an integral, fused, foam backing,
118
also preferably formed of vinyl resin. The thickness of the backing is suitably about ⅛ inch.
Standard elastomeric suction cups having a diameter of about ½ to 2 inches are satisfactory for use on smooth walls such as fiberglass, reinforced polyester, vinyl, acrylic or ceramic shower or tub wall surfaces. However, in walls tiled with discrete tile pieces such as squares, rectangles, hexagons etc. the spaces between tiles containing grout are relieved and cannot seal with suction cups. Referring now to
FIG. 6
, in accordance with a preferred aspect of the invention, the mounting means provided at the corners of the back surface
120
of the scrubber
100
contain a plurability of individual, small suction cups
122
. The small suction cups
122
can be mounted on a sheet
124
secured the surface
120
by adhesive or other suitable adhesive means such as thermal bonding, ultrasonic bonding etc. The small suction cups
122
are present in groups of at least 3 up to as many as desired. The diameter of the mini suction cups
122
is suitably from {fraction (1/16)} to ½ inch, usually about ⅛ to ¼ inch.
The scrubber can readily be manufactured from non-woven continuous or discontinuous lengths of filaments of organic resins, preferably hydrocarbon resins such as vinyl, polyethylene or polypropylene resins. The discontinuous filaments can be bent into loops and embedded in a resin backing. The filaments can be bonded together into a mat layer and bonded to or embedded in a resilient backing such as closed wall foam formed of the same resin. Thermoplastic resins such as vinyl can be thermobonded. The resins can be compounded with antibacterial and antifungal agents.
The mat can be made from material similar to that used as door mats or floor mats. The material is cut into mats from 6-8 inches wide by 10-12 inches long. Suction cups, suitable made of polyurethane are embedded in the backing and/or adhesively secured to the backing of the mat. The weight basis of a scrubber mat formed of resin filaments is suitably 1-10 pounds per square yard; generally around 5.5 pounds per square yard. The thickness of the mat is usually from 0.2 to 1.0 inch, usually about ½ inch.
Mats formed from vinyl resin can be compounded to have antibacterial and antifungal properties. They have excellent resistance to water and to soaps and detergents. They can be readily provided in colors by adding dye to the vinyl resins before spinning the filaments. The backing can be formed by immersing a portion of the loops in liquid vinyl resin and hardening and curing the liquid to form a rigid or resilient backing. The scrubber need not be rectangular. It can be prorated in other polygonal shapes or in irregular shapes manufactured.
The bath scrubber is used as follows:
1. Wet suction cups and stick on shower wall at chest height; or at end wall of bathtub.
2. Wet scrubber and lather with soap.
3. Rub back on scrubber.
4. Leave scrubber in position and rinse with clear water. The scrubber will not mildew.
It is to be realized that only preferred embodiments of the invention have been described and that numerous substitutions, modifications and alterations are permissible without departing from the spirit and scope of the invention as defined in the following claims.
