3 Claims. (Cl. 206-47) This invention relates to pads and in particular to composite disposable cleaning or polishing pads.

This invention is designed .to overcome many of the disadvantages of the current cleaning and polishing pads and also to provide cleaning or polishing pads which are capable of uses not contemplated by pads commonly in'use, as set forth hereinafter. The present invention is designed especially for cleaning automobile windows. Automobile windows are frequently dirtied and smeared by dust, mud, oil, grime and bugs. Such a condition of the windows makes driving quite hazardous, particularly at night, and endangers the lives of the occupants of the automobile as well as others who might possibly be involved in an accident caused by faulty vision through the automobile windows. useful in cleaning or polishing of materials such as glass, cloth, paper, leather, metal, wood, and the like.

The cleaning or polishing pads commonly in use are dependent upon a separate supply of cleaning or polishing compound. The devices in common use for cleaning automobile windows are dependent upon a supply of water which may not be available readily in an extended trip, especially should the trip necessitate travel through relatively unpopulated areas. However, the cleaning pad in one embodiment of this invention is not dependent upon a separate supply of cleaning fluid or cleaning compound, nor upon an outside source of water and hence is ideally suited for use in the cleaning ofautomobile windows under all kinds of conditions and in all locations.

Likewise, many of the polishing pads now in use are also dependent upon an auxiliary supply of polishing compound. Such auxiliary supplies are not desirable since the polish containers fail to be air tight once they have been opened and hence the polishing compound becomes deteriorated and loses its effectiveness. However, the present polishing pad is not, dependent upon such auxiliary supply of polish and hence the polishing compound is not subject to deterioration.

Also, this invention provides a compact shoe polishi ing pad capable of being packed conveniently in a suitcase for use while traveling without soiling clothing placed adjacent thereto andwithou't the necessity of a separate kit to house the shoe polish equipment.

in general the present invention contemplates a composite disposable pad, comprising an applicator pad and a bufiing or drying pad separated by a fluid-impervious barrier sheet which extends beyond the edges of the pads. This barrier sheet is sealed at its marginal por.

tions to fluid-impervious sheets covering each of the pads to thereby form envelopes for each of the pads. The applicator pad preferably is attached to the interposed barrier sheet, while the other pad, the buffing or drying pad, may be free in its envelope.

The applicator pad is used to apply a cleaner or polish to a surface to be treated. The buffing or drying pad is used as a bufiing pad to buff the surface to which The composite pad is also polish has been applied, or used as a drying pad to remove the dirt and grime loosened by the cleaning com-,

' erably located between the applicator pad and the barrier sheet.

The two fluid-impervious envelopes prevent the passage of fluids therethrough and hence prevent the deterioration and loss of the material to be applied either when the applicator pad contains the material or when it is contained in the frangible capsule which might be broken accidentally. In addition, the envelopes prevent the soilage of both pads prior to their usage. The fluidimpervious barrier sheet prevents the passage of the cleaning or polishing compound from the applicator pad to the bufling or drying pad and hence maintains this pad in its original condition prior to its use.

For cenvenience in gripping the composite pad, the envelope enclosing the bufling or drying pad may be provided with a handle. This handle may be formed by a pleat in the envelope.

The invention will be described further in connection with the accompanying drawings which show several embodiments of the invention. These drawings are used as means of exemplification of the invention and do not constitute limitations thereof. The invention is to be limited only to the scope of the appended claims.

Fig. 7 is an elevational view of the pad shown in Fig. 5, showing the handle in a folded position and the envelopes in their sealed position.

in the embodiment shown in Figs. 1 and 2, the composite disposable cleaning or polishing pad comprises two pads 31 and 2, preferably of cellulosic material such as cotton, cloth, fiufied wood pulp, or one of the newer highly swelling celluloses, placed back to back. These two pads are separated by a fluid-impervious barrier sheet 3 formed of heavy waxed paper, cellophane, thermoplastic material, or the like, extending beyond the edges of the two pads and lying between the pads in plane parallel thereto. The applicator pad ll preferably is attached to the barrier sheet by suitable means, such as a mastic or by heat sealing when using a thermoplastic material as Patented Jan. 29, 1957 the barrier sheet. Fluid-impervious covering sheets 4 and lie on the outer sides of the pads 1 and 2 respectively and parallel thereto. These sheets are made of some suitable material, such as cellophane or hydroxyethylcellulose. The covering sheets 4 and 5 are sealed to the barrier sheet 3 along its marginal portions whereby the two pads are enclosed in individual envelopes with the drying or buffing pad 2 preferably being loose in its envelope. The applicator pad in this embodiment contains a cleaning or polishing compound applied to the pad by coating, impregnation, or the like.

Figs. 3 and 4 show a second embodiment of this invention wherein identical elements have been designated with the same numerals employed in Figs. 1 and 2, with the addition of a character a after the numerical designations. in this embodiment there is a frangible capsule 6 containing a cleaning or polishing compound, either with or without a solvent or dispersing agent placed be tween the applicator pad 1a and the barrier sheet 3a.

In the embodiment shown in Figs. 5, 6 and 7, elements identical with those in Figs. 1 and 2 have been designated with the same numerals with the addition of the letter b after the numerical designation. The composite disposable pad of this embodiment is provided with a handle 7 which conveniently may be formed from a diagonal pleat in the covering sheet 5b. This pleat may be folded so that it lies fiat against sheet 51) for convenience in packing, as shown in. Fig. 7. This pleat may be unfolded, as shown in Figs. 5 and 6, so that it lies perpendicular to the surface of the composite pad and serves as a handle during the application step. This pleat could also be formed in sheet 5'41 covering the drying or buffing pad 2a of the embodiment shown in Figs. 3 and 4, wherein a frangible capsule is employed.

The applicator pad should be fairly substantial and in a rather compact formto enable it to withstand the abuse occurring during application of the cleaning or polishing compound.

For ease of identification of the two pads, the envelope containing the applicator pad may be tinted differently from that containing the drying or buffing pad. This would be especially desirable in the embodiment wherein the applicator pad is impregnated and no handle is provided on the envelope enclosing the drying or buffing pad to differentiate it from the applicator pad.

The impregnated composite pad, shown in Figs. 1, 2, 5, 6 and 7, is used by removing the sheet 4 or 4b which covers the applicator pad 1 or 112. The applicator pad is moistened if necessary, depending upon the type of cleaning or polishing compound with which it is pro vided, and the cleaning or polishing compound applied to a surface by gripping the drying or bufling pad 2 or 2!), or by gripping handle 7 and rubbing the applicator pad against'the surface. With such an arrangement the cleaning or polishing compound is applied readily to a surface, but the water-impervious barrier sheet 3 will prevent the compound from penetrating the bufiing or drying pad which is still enclosed between the fluid-impervious barrier and the covering sheet for that pad; and the hands of the user will not be soiled.

The cleaning or polishing compound is applied by the embodiment shown in Figs. 3 and 4 by squeezing the applicator pad in to crush the frangible capsule 6 and then removing the sheet 4a covering-that pad. The applicator pad may be moistened if the capsule does not contain a solvent or dispersing agent and if moisture is desirable. The cleaning or polishing compound is then applied to the surface to be cleaned or polished by gripping the drying or buffing pad 2a which is still enclosed in its envelope and rubbing the surface to be cleaned or polished.

After the cleaning or polishing compound has been applied to the surface, thesheet 5, 5a, or 5b covering the drying or buffing pad is removed and the pad taken out of the envelope for use in removing the dirt and cleaning compound from the surface or for use in buffing the polish on the surface. After the cleaning or polishing operation, both pads may be disposed of.

While the invention has been described in connection with the above embodiments only, it will be understood that various changes may be made in the details of con struction without departing from the invention or sacrificing any of the advantages thereof.
