Title: Combined soft/abrasive cleaning sponge width projecting peaks with rounded tips

Description:
BACKGROUND TO THE INVENTION 
     For years, in all types of places such as homes, factories, restaurants, bathrooms, hotels, etc., people have used sponges or scourers to facilitate the cleaning of all those encrusted bits of dirt or grime that require hard scrubbing. 
     These scrubbing pads are numerous and varied in design, however, as far as I know, a scrubbing pad does not exist with the simple and yet very important characteristics of the one I have invented. 
     As will be obvious from the description and enclosed drawings, this invention offers a transcendental advantage in that while being only one sponge it has two faces, one being soft and the other highly abrasive allowing the sponge to rub softly or abrasively to clean an object. In addition, the multiple edges located on the peripheral sides of the sponge give it the indisputable advantage of being able to penetrate areas where other sponges cannot because the edges operate (as proven in experiments) as repetitive tips that incredibly remove accumulated dirt or grime from the inner corners and hard to reach places of objects being cleaned. 
     DESCRIPTION OF THE INVENTION 
     The invention is ilustrated in the accompanying drawings showing a preferred embodiment including specific parts and arrangements of parts. It is intended that the drawings, included as part of this specification be illustrative of a preferred embodiment of the invention. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     FIG. 1. Shows a plan view of the the abrasive section of the sponge. 
     FIG. 2. Shows a plan view of the the soft section of the sponge. 
     FIG. 3. Shows a sectional transverse view on which both soft and abrasive sections are shown. 
     FIG. 4. Shows a cross section of the sponge. 
     FIGS. 5,6,7,8 and 9. Show the different possible shapes the sponge can assume. 
    
    
     Referring now to the drawings, the sponge comprises in combination a body, which is in turn formed by two sections (2 and 3). The soft section (2) which has as its principal characteristic its external face (2a) totally free of any elements than the natural softness of said face (2a). The abrasive section (3) which is manufactured to form an integral body with the soft section (2) provides on its external face (3a) an extremely abrasive surface, rough enough to remove all the dirt and grime encrusted in the area to be cleaned. 
     The surrounding area of the sides (4) of the sponge, which includes the soft section (2) and the abrasive section (3) is provided of a plurality of projecting salients (6), in a zig-zag pattern, with rounded tips (5) that at one end (5a) are highly abrasive and at the other end (5b) are soft. 
     As long as the surfaces to be cleaned do not have any awkward areas for wiping, the sponge can slide as easily along the surface as any other sponge on the market today. Alternatively, when the cleaning is carried out in areas with angles such as the inner converging walls of an object, the peripheral rounded tips (5) are effective for the required cleaning position, which means to say, by introducing the soft edge, the abrasive edge or if necessary both edges alternately. 
     According to the task undertaken, the sponge can assume different shapes, for example for an easy approach to washing dishes the shape in FIG. 5 would be used, if the sponge was, to be used for cleaning bathroom areas, the shape in FIG. 6 would be used, if the sponge was to be used for cylindrical containers the shape in FIG. 7 would be used, if the sponge was to be used for square shaped containers the shape in FIG. 8 would be used and so on. For this reason as I have already pointed out I do not intend to limit the specified shape of the sponge but rather intend to patent the innovative combination of soft (2) and abrasive sections (3), projecting fibers and rounded tips which when acting together are the very essence of my invention.
