The invention has for another object' to provide a resiliently compressible scouririg implement comprising an internally cushioned hollow seamless body, said body being made of atoughffieii- "ible Vand somewhat resilient and-liquid impervir@Us or non-absorbent material which also serves as a matrix for securely holding particles of pillverized abrasive material with which'the sameis l charged. r l t 'l Theinvention has for a more specific object f t 'provide a hollow, seamless body oontairiinea llshioning means or c ore of dry, fibrous material,
[said body. in a preferred enibodimentv thereof,
being made from a composition consisting of copolymers of both vinylv Chloride and vinyl acetate in relative proportions whereby the zo-polymers ofl vinyl chloride predominate, so that the'ire- `sultant body is not only tough, exible and ysomewhat resilient and well adapted to lserve as -al matrix for eourelyholding a pulver-ized abrasive material'v incorporated therewith, butis also .impervious to liquid or non-absorbent whereby to prevent water or other cleaningfluid from gaining access to the internal fibrous'` cushion means or core so that the latter-not only remains dry and springy, andfree from tendency to become soggily matted down, asy would be the case if saturation thereof with Water or other cleaning fluid were permitted, but also remains free Y from accumulation of dirt, grease or the like,
which 'would otherwise Vbe likelyv to `ir'ivitelmncdity'and vother unsanitary conditions* Otherobjects of this inventionli'not at this time l more particularly enumerated,v will beunder-r stood from the yfollowingI detailed descriptionl of thesamef l A Illustrative embodiments ofthe'i'nvention are shown in the accompanying `dravvirrg;in which;-

,The lnovel scouring device according' to `this invention kis formed by a hollow y seamless body Illl of Vany desired external shape, but which. is

The plastic material also providesy a matrix for strongly gripping and holding, especiallyat,` the i external surfaces thereof, the pulverized abrasive rnateriall or grit H desired to be incorporated therewith. The internalcushioning of said hollow seamless body I0, whereby the latter is yieldable supported and backed, may be vvariously accomplished. Preferably, however, the hollowlrlterior o f said seamless body lrllsllled withamass y'of dryf'a'ndspringy fibrous material adapted to provider'a resilient cushioning core l2; 'Said` f1- brous material may be of any desired'or suitable kind. such as. a mass of vegetable. animalormineral libres, cellulose or the like.
