This invention relates, generally, to improvements in cleanser devices; and the invention has reference, more particularly, to a novel hand implement for general Washing and cleaning operations, such as shown in my prior Patent No. 2,026,638, datedJanuary '7, 1936,r which discloses a foraminous resilient body having portions of its surface area covered with metallic mesh.
The invention has for an object to provide a cleanser device comprising a hollow resilient porous body, such, for example, as provided by sponge rubber, the interior of which is filled with a mass of fibrous material alone or treated with a saponaceous substance, or with any Asuitable form of saponaceous substance alone or in combination with a carrier therefor, or mixed with other ingredients calculated to contribute to cleansing or other effects by which the device is desired to be functionally characterized; said body also including elements adapted to effect an abrasive or scouring action upon the surfaces to which it is applied when conducting a cleaning operation.
Other objects of this invention, not at this time `more particularly enumerated, will be understood from the following detailed description of the same.
Illustrativeembodiments of this invention are shown in the accompanying drawing, in which:
Fig. 1 is a face. view of one form of the cleanser device according to this invention, showing the same provided with a facing of metallic mesh fabric to serve as a scouring or scraping medium; Fig. 2 is a longitudinal sectional view of the same; and Fig. 3 is a fragmentary longitudinal sectional view of a modified form of this type of cleaner device.
Similar characters of reference are employed in the hereinabove described views, to indicate corresponding parts.
Referring to the drawing, the novel cleanser device according to this invention is shown therein to comprise a suitably shaped hollow body oi' resilient porous material, 4such e. g. as sponge rubber. In one form, as shown in Figs. 1 and'2, the hollow body comprises a hollow or chambered upper section ,I0 providing an interior chamber Il, and a bottom section I2 suitably secured to` said upper section Ill in closing relation to said chamber Il. Owing to the interstitial or highly porous character of the hollow body, its walls are pervious to liquids. Enclosed within the hollow body, so as to ll the interior thereof, is a mass l of fibrous or illamentar'y material i3. This filler mass while more or less compacted is, nevertheless. yieldable or resilient, and consequently suitably supports or backs the walls of the hollow body when the same is applied to a surface to be cleaned;l and, in fact, the body, due to its own resilient character and that of the filler mass therein, will readily conform itself to the contours .3 of the surface to which it is applied and pressed, and over which it is rubbed. when employed in cleaning such surface. The filler mass i3 may comprise any suitable material; for example, wood shavings, excelsior. vegetable fiber, or a mass of 1u illamentary material of any other specific character may be employed.
It will be obvious that in the use of the device, in the simple form above described, and owing to the pervious character of its body and of the filler l5 mass contained therein, that the same will take up and then emit during cleaning operations therewith, any desired cleansing liquid. such, forv example, as soapy water, cleaning oils, or the like.
In a preferred embodiment of the invention, the 2U filler mass comprises woody or other preferably absorbent fibrous material which is impregnated. at the time of manufacture of the device, with a suitable saponaceous material; the filler mass in such case serves as a carrier for the saponaceous 25 substance, and consequently, when the device is wetted preparatory to use, the liquid will enter and contact with the saponaceous substance carried by the filler mass to form a soapy mixture which will be expressed from the device as it is 3u rubbed over a surface desired to be cleansed.
If desiredthe bottom section of the device, instead of being made of interstitial or porous material, such as sponge rubber. may comprise a vulcanized mass of rubber filled or impregnated with 35 a pulverant abrasive material, such e. g. as powdered emery, carborundum, pumice stone, or thev like, as indicated at i5 in Fig. 3. The bottom section I5 thus provided may be vulcanized directly to the sponge rubber upper section l in 40 closing relation to the interior chamber Il thereof, thereby assuring a secure and irremovable relation of the one to the other.
As also shown in the drawing, a metallic mesh fabrici6 is applied over 'the top and around the 45 sides of the upper section I 0 of the device. This mesh 'fabric i6 is preferably of a knitted formation, produced from flat ribbon-like wire or strand, although other cross-sectional shapes of the wire or strand may be employed. It is also preferable that the wire or strand employed in the production of the mesh fabric be of a substantially non-corrosive metal, such e. g. as zinc, copper orA aluminum. The free marginal portions Il of the metallic mesh fabric II are turned under 'upon the mesh marginal portions Il, so that the mesh fabric i6 will not loosen from its enveloping relation to the exterior surfaces of the upper section l0 of the device when the latter is subjected to the strains of use. In utilizing the thus modified form of cleanser device, the foraminous body sections and its filler mass may be wetted to exude a saponaceous cleaning liquid when rubbed over a surface to be cleaned, while at the same time its mesh faced areas, being resiliently backed by the body of the device, will be firmly pressed against and in conforming relation to said surface, so that, as the device is rubbed back and forth upon the latter, the edges of the metallic loops of the mesh will exert a strong scraping effect, well calculated to loosen and scrape away encrusted and caked dirt and soil; especially is this so;when the wire of the mesh is of fiat ribbon-like or otherv angular cross-sectional form, since, in such case, sharp chisel-like edges are presented in various directions which assure a highly emcient scraping action.
It will be understood that further'V modifications of the specie details of construction and form, other than those already indicated, may
l. A cleaner device comprising a resiliently compressible hollow body adapted to enclose eX- pressible saponaceous material, portions of the body wall being made of sponge rubber through which saponaeeous material may be expressed, and a metallic mesh secured to said body in externally overlying relation to the sponge rubber wall portions thereof.
2. A cleaner device comprising a resilientlycompressible hollow body adapted to enclose expressible saponaceous material, portions of the wall body being made of sponge rubber through which saponaceous material may be expressed, and an abrasive mesh of knitted ribbon-like metallic wire secured to said body in externally overlying relation .to the sponge rubber wall portions thereof.
