2 Claims-.-` (Cl. 15- 122) The present invention relates to.,an improved cleaning .device in the form of a holder or receptacle Within which a suitabledetergent or cleaning agent is placed, whichis intended to seep through orfpenetrate one orzmore walls of the holder, constructed vof anylsuitable material oi a porous nature, such, for example, as sponge rubber.:

One object of the inventionis lto provide an A#improved `device of this class which is of simple construction, eiicient in operation, and one which embodies but few parts capable of being conveniently assembled and separated when desired.

A further object of the `invention is the provvision of an improved-detergent holding receptacle for use as a cleaning device in which the walls are formed of complemental sections, detachablyvretained in assembled relationwith` out the-useof additional securing parts for the same.

A further vobject of the invention is` the provisionj of anfiinprovedreceptacle -forth purpose described comprising cooperating l recessed.l sec tions'inser-ted fone within'another and having in# terengagingportions affordin'gta gripping actionbetween the sections wherebythey are firmly-held#v in detachable relationthrough lfrictionalf engagew mentof Aone-with another.l

A further object of` the inventionisto provide l ina receptacle of this class vcooperating sections,

one -havingreinforcements for strengtheningl the f same`- androne beingy impervious -ito `liquid While another has .one ormoresof its-walls `formed of porous or cellular. materiali such, vforexample; assponge -rubbenthroughrwhich a liquid or semi# i liquid detergent may bel` permitted to` @seep or escape.: when `rubbingfthe porous portion-of the receptacleupon` the surface to becleaned.

Toythese and other ends 'theinvention'` resides 1 in certain improvements and combinations off' Fig. 2;

Fig. 4 is a similar section with the cover of the receptacle removed;

Fig. 5 is a transverse section through the base of the holder showing in perspective an inverted end portion of the same, and

Fig. 6 is a fragmentary view in perspective illustrating the end construction of the base or bottom section of the holder.

The same reference numerals throughout the several views indicate the sameparts.

The present invention embodies a recessed holder for the reception of a detergent or cleansing material which may be in the form of a liquid, semi-liquid, or solid. In the case of the latter, such as a cleaning powder or cake of soap, the holder or receptacle may be dipped within Water or other liquid, a certainlproportion of which will enter the receptacle through the porous walls thereof whereby upon rubbing the holder upon a surface to be cleaned, the resulting lather or liqueed soap will eiectively cleanse the same. This, of course, will also `be true where a liqueed soap or other liquid cleansing material` is placed within the holder which will escape therefrom when pressure is applied thereto by the H hand of the operator when rubbing the holder upon the surface which it is desired to clean. While the device may be used for cleaning various articles, it is particularly adapted for use in cleaning windows, bathtubs, sinks, and other articles formed of glass, porcelain, and the like.

Referring to the drawing, the reference characters l0 and il designate generally the base and cover sections, respectively, of the improved cleaning device, the former being inserted within the latter as shown in Fig. 2 of the drawing.

The entire base section is preferably formed of cellular or porous material such, for example, as sponge rubber, although if preferred it may be formed of other suitable material.

In l the present disclosure, the skin or rind, forming upon the section l0 of the receptacle as a result of the process of manufacture, is removed from the inner and outer faces of the bottom Wall l2 of the section to render it pervious l to liquid or the liquefied cleaning material placed within the receptacle.` The surfaces from which the skin has been removed are indicated bythe stippled surfaces shown in Figs. 5 and 6 of the drawing, the surfaces which are not stippled being left with the skin or rind intact to render them impervious to the cleaning fluid used within the receptacle or to any liquid coming into contact therewith,

The cover Il, within which the base or body section I0 extends, is preferably formed of a good grade of non-porous rubber or other material impervious to liquid and having sufficient elasticity to permit it to be slightly stretched i when inserted upon the base whereby to better as shown in Fig. 2. This construction, however,

permits the sections to be readily separated by moving one laterally of the other.

While the shape of the receptacle may be varied as desired, it is preferred to provide the opposite side walls I5 of the bottom section IB with a plurality of angularly disposed end walls, preferably three at each end, the two which form a direct continuation of the side walls being designated by the reference character I6, and the Y third or centrally disposed wall by the reference character Il. Thus the side walls are braced by the angularly disposed end walls whereby the rigidity of the receptacle is increased in order that it may better withstand the pressure applied thereto during the cleaning operations, the construction being such as to prevent collapsing of the receptacle when used for the purpose intended.

It will be understood, of course, that the cover section II will conform generally to the shape of the body section I0 and will have the corresponding arrangement of side and end walls shown in Fig. 6.

The bottom section Ill of the receptacle is provided adjacent the grooves I3 with an outwardly extending flange or lip I8 which serves to increase the area of the cleaning portion of the base section and which also forms a supporting shoulder for the beaded edge I 4 of the cover II, as shown in Fig. 2. This is advantageous since the pressure exerted by the hand of the operator on the cover is transferred directly to the said flange whereby the latter will be made more serviceable as a means for effecting removal of such dirt particles as tend to cling to the surfaces to be cleaned, it being understood that the cover section of the receptacle is preferably formed of a grade of rubber having greater resistance to pressure than that of the spongev rubber base and will therefore tend to urge the bottom or edge portion of said flange into engagement with the surfaces to be cleaned.

Furthermore by positioning the flange of the base and the enlarged beaded portion of the cover in juxtaposed relation, the rigidity of the receptacle is increased at the proper point and the more or less flexible side walls of the sponge rubber section will be correspondingly relieved of the pressure which would otherwise be applied thereto. f

' grip the walls of the latter, thus insuring its re- The cover section I I of the receptacle or holder is provided at its corners with thickened wall portions l 9, Fig. 3, which serve to increase the rigidity of the section whereby it will better hold its shape and withstand the pressure applied thereto by the hand of the operator when gripping and using the holder from time to time.

The bottom wall I2 of the base has its corner portions rounded as indicated at 2li, said portions preferably forming seats for the lower edges of the thickened wall portions I9 of the cover and conforming generally to the shape or contour of said thickened wall portions.

It will be understood that with the cover II in closed position, as shown in Fig. 2, the receptacle will be liquid-tight, except for the porous wall I2 of the bottom section I0, from the opposite faces of which the skin or rind has been having exteriorly formed grooves therein, and a cover section for said hollow section formed of substantially rigid material impervious to liquid, said cover section including side walls surrounding the side walls of the hollow section, the peripheral edge portion of the cover section engaging the flange of the hollow section and serving to urge said flange in engagement with the sur-V face to be cleaned when pressure is applied to the cover section in the direction of said flange, said cover section having bead-like portions on its side walls extending within the grooves of the side walls of the hollow section by which the cover section is retained on the hollow section.

2. A cleaning device of the class described comprising a substantially rectangular hollow section formed of sponge rubber and including a bottom wall and upstanding side and end walls, said bottom wall having a flange extending laterally from the side and end walls, andY a cover section for said hollow section formed of sub- Y ARTHUR O.
