Full Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     This invention relates to liquid containers used for storing cleaning liquid so as to be available in the cleaning process, specifically mopping buckets having divided liquid container sections for clean and dirty water. 
     2. Description of Prior Art 
     Prior art devices of this type have relied on a variety of bucket configurations associated with floor mopping use criteria, see for example U.S. Pat. Nos. 3,829,926, 4,319,761, 4,798,307, 5,918,343, 6,098,805 and 6,260,230. 
     In U.S. Pat. No. 3,829,926 a paint bucket is disclosed having four sides with integrated spout and roller engagement sides within. 
     U.S. Pat. No. 4,319,761 is directed to a mop bucket in which a clip configuration registerably engaged within a pair of buckets, securing them together. 
     U.S. Pat. No. 4,798,307 claims a compartmentalized cleaning buckets having a pair of reservoirs within for separation of clean water from dirty water during use. 
     A combination bucket and ringer is shown in U.S. Pat. No. 5,918,343 in which a bucket has an integrated mop/ringer therewith. 
     U.S. Pat. No. 6,098,805 is on a dual bucket assembly in which a bucket has two liquid retaining chambers therewithin that are nestable with a second identical dual bucket to be positioned within during storage or shipping configurations. 
     Finally, U.S. Pat. No. 6,260,230 is directed towards a floor washing and drying method using combination apparatus which has a first and second liquid reservoir within. A mop can be used with the first reservoir having a ringer associated therewith. 
     SUMMARY OF THE INVENTION 
     A cleaning bucket system for use in janitorial floor cleaning applications in which two reservoirs for water are required. The bucket system combines a mobile holding enclosure in which a pair of independent buckets are removably positioned therewithin. Each independent bucket can be used separated or as an integrated pair for clean and dirty water containment utilized in commercial cleaning applications.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIG. 1  of the drawings, a cleaning system container assembly  10  of the invention can be seen having a main enclosure  11 . The enclosure  11  has oppositely disposed spaced parallel sidewalls  12  and  13 , interconnecting end walls  14  and  15  and an integral bottom  16  therebetween. 
     Pairs of wheel assemblies  17  are secured to the opposing enlarged bottom corner intersections extending from the respective wall corners thereof. The end wall  14  has a pour spout extension  14 A formed within upper perimeter edge. The end wall  15  extends angularly beyond respective upper perimeter wall edges  12 A and  13 A to accommodate mounting of an associated mop ringer assembly (not shown) as will be well understood by those skilled in the art. 
     The hereinbefore described side and end walls  12 ,  13  and  13 ,  14 ,  15  and integral bottom  16  define a area  19  which could act as a holding tank for liquid, if required. The dimensional characteristics of the enclosure  11  are such that its longitudinal length is greater than its transverse dimension defining the respective end walls  14  and  15 . A pair of independent bucket inserts  20  and  21 , best seen in  FIGS. 1 and 2  of the drawings, each defined by multiple wall pairs  20 A,  20 B, and  21 A,  21 B, respectively with interconnecting bottoms  20 C and  21 C adapted for holding a liquid as will be understood by those skilled in the art. The bucket&#39;s respective walls have corresponding upper lip edges  22  and  23  thereabout and each have an integrated pour spout  24  and  25  formed in one of the wall pairs  20 A and  21 A respectively. 
     In this preferred embodiment of the invention, indexing ribs  26  may extend vertically on inner sidewall surfaces thereof midway of the longitudinal length of the enclosure  11  thereof in oppositely disposed aligned orientation to one another. The indexing ribs  26  act as positioning guides for insertion of the respective buckets  20  and  21  which are oriented for the clearance of their respective molded pour spouts  24  and  25 , as best seen in  FIG. 2  of the drawings and in dotted lines in  FIG. 4  of the drawings. 
     Each of the hereinbefore described bucket inserts  20  and  21  registerably engage the corresponding sidewalls  12  and  13  and respective end walls  14  and  15  and extend marginally thereabove. 
     Bucket handles  29  and  30  are pivotally secured to the appropriate oppositely disposed walls  20 B of the bucket inserts  20  and  21  for ease of positioning and removal as will be evident to one skilled in the art. 
     The dual bucket inserts  20  and  21  provide for independent removable liquid reservoirs (for clean and dirty water) within the integrated movable cleaning container assembly  10  of the invention. Since the bucket inserts  20  and  21  can be selectively removed via their handles  29  and  30  for filling and dumping an improved and efficient working environment can be achieved. 
     It will also be evident from the above description that by the corresponding shape of the bucket inserts  20  and  21  that they will registerably engage and be properly positioned within the end source  11  for ease of access during use and afford convenient and simple filling and emptying which is not evident in prior art integrated divided multiple enclosure configurations which are fixed therewithin. 
     It will thus be seen that a new and novel cleaning container assembly has been illustrated and described and it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention.
