Description:
FIELD OF THE INVENTION 
     The present invention relates generally to an effluent container. More particularly, the present invention relates to a disposable bag configured to contain effluent generated during the cleaning of a fin fan cooler. 
     BACKGROUND OF THE INVENTION 
     From time to time coolers, such as fin fan coolers, are in need of cleaning. One way of cleaning a fin fan cooler is to flow cleaning fluid (which is often water) through the fin fan cooler. As the cleaning fluid moves through the fin fan cooler, the cleaning fluid may pick up contaminates from the cooler. The contaminates may have leaked from the cooler or may be present due to other sources. One tool that may be used in the cleaning process is a hydroblaster. The hydroblaster may discharge cleaning fluid through a fin fan cooler causing the cleaning fluid to flow through the fin fan cooler and out the other side of the cooler. 
     In view of current environmental concerns, it may be desirable to recapture the cleaning fluid once it has flowed through the fin fan cooler. Recapture of the cleaning fluid may be desirable because the cleaning fluid itself may need proper disposal or that the cleaning fluid, once it has been contaminated by being flushed through the cooler becomes an effluent that now contains contaminates that need to be properly disposed of. 
     Further, it is possible that a fin fan cooler may leak causing an effluent to flow out of the cooler. 
     Accordingly, it is desirable to provide an apparatus that allows an effluent flowing out of a structure such as a fin fan cooler to captured for proper disposal. 
     SUMMARY OF THE INVENTION 
     The foregoing needs are met, to a great extent, by the present invention, wherein in one aspect an apparatus is provided that in some embodiments provide an apparatus that allows an effluent flowing out of a structure such as a fin fan cooler to captured for proper disposal.

     DETAILED DESCRIPTION 
     The invention will now be described with reference to the drawing figures, in which like reference numerals refer to like parts throughout. An embodiment in accordance with the present invention provides a container that may be easily attached to a structure that may be a source of an effluent. The container will allow the effluent to be recaptured for proper recycling, reclamation, or disposal. In some embodiments, the container will be inexpensive and easy to dispose of so that the container itself does not require cleaning or create a problem for disposal. 
       FIG. 1  is a perspective view of a container  10  in accordance with the present disclosure. The container  10  is attached to a source  12 . The source  12  is a structure upon which the container  10  is attached. The source  12  may contain or be a fin fan cooler. At side opposite of the source  12 , (not shown) a hydroblaster may be cleaning the fin fan cooler causing a cleaning fluid to flow through the fin fan cooler. The cleaning fluid may pick up contaminants in the fin fan cooler creating an effluent. The effluent is captured by the container  10  when the effluent flows out of the fin fan cooler. 
     The hydroblaster is used to perform hydroblasting operations using a hydroblasting fluid under extreme pressure, which may include a blast of water, with an added abrasive, to remove grime or other deposits from the interior of the source  12 . The fluid and debris may also consist of hazardous materials. During a hydroblasting operation, the hydroblaster may be used to spray the fluid at a working pressure within the range of 10,000 PSI and 40,000 PSI. 
     The container  10  has an open end  14 . The open end  14  exposes the interior  15  of the container  10 . The container  10  is secured to the source  12  by closing structure  16  such as straps  16 . Although straps  16  are illustrated in the accompanying figures, other closing structure  16  may be used in accordance of the present disclosure. Closing structure  16  that may be used in accordance with the present disclosure may gather the open end  14  around the source  12  so as to close gaps between the container  10 , and the source  12  and secure the container  10  to the structure defining the source  12 . 
       FIG. 2  is a perspective top and front end view of the container  10 . The container  10  is made primarily of material  18 . The material  18  may be polyethylene in a sheet form. In some embodiments, the polyethylene is low density polyethylene (LDPE) and may be reinforced with fibers such as, for example, but not limited to, nylon. Several layers of material  18  are used in the construction of the container  10 . For example, as shown in  FIG. 2 , a top sheet of material  20  is located above the bottom sheet of material  22 . The top material  20  and the bottom material  22  are connected at seams  24 . In some embodiments, the seams  24  are located around the outer edges of the top material  20  and the bottom material  22  with the exception of one edge. This one edge where the top material  20  is not connected to the bottom material  22  defines the open end  14 . 
     In some embodiments, the top material  20  and the bottom material  22  may be constructed in a multiple plies. In other words, the top material  20  may be actually two or more sheets. In some embodiments, the top material  20  and the bottom material  22  are two ply sheets. The top material  20  and the bottom material  22  may be attached in a variety of ways to form the seams  24 . For example, the seams  24  may be formed by sewing, heat welding, sonic welding, impulse welding, epoxies, adhesives, or any other suitable way of attaching sheets together. 
     The straps  16  may be equipped with multiple buckles  26  as shown. The buckles  26  may assist a user in tightening the open end  14  around a source or other structure  12  to which it is desired to attach the container  10 . 
     In some embodiments, the open end  14  of the container  10  may be equipped with attaching structure  28 . In the embodiment shown in the figures, the attaching structure  28  may be in the form of loops  28 . The loops  28  may be made of the material folded back over itself and attached to the container  10  at various seams  24 . The attaching structure  28  may provide another way for the container  10  to be attached to a structure  12  or otherwise provide a structure to move or secure the container  10 . 
     In addition to having an open end  14 , the container  10  has a closed end  30 . The closed end  30  is surrounded by the seams  24 . In some embodiments, the container  10  may have a generally rectangular shape, however, as shown in  FIG. 2 , the closed end  30  may be formed of two seams  24  that are at an obtuse angle to each other. In instances where the container  10  is rectangular in shape, the container  10  may have three long seams  24  which attach the top material  20  to the bottom material  22 . In embodiments having more than four sides, as shown in  FIG. 2 , there will generally be more than three seams  24  attach the top material  22  the bottom material  22 . 
       FIG. 3  is a bottom view of the container  10  in accordance with an embodiment of this disclosure. The bottom material  22  or sheet  22  is seen attached by various seams  24  to the top material  20  or sheet  20  (not shown in  FIG. 3  but is a readily seen in  FIG. 2 ). The straps  16  along with the buckles  26  are readily visible. The straps  16  may be attached to each other serially to form a single long strap or belt. The strap  16  may reside in a strap loop  32 . The strap loop  32  may be comprised of the material  18  folded back on itself to form a loop and is attached to the container  10  by a seam  24 . The strap loop  32  may have various breaks or openings  31  or windows  31  in order to allow a user access to the strap  16  and, in some embodiments, the buckles  26 . 
     Portions of the strap  16  and the buckles  26  are illustrated in  FIG. 3  to reside in the strap loop windows  31 . The portions of the strap  16  that are located in the strap loop  32  are shown in broken lines  FIG. 3 .

     In some embodiments, the liner  34  is attached to top material  24  the bottom material  22  by a retaining flap  36 . The retaining flap  36  may be made of the same material  18  as the top material  20  or sheet  20  and the bottom material  22  or sheet  22 . The retaining material or flap  36  may extend beyond the liner  34  toward the closed end  30  to form a loose end  38  as shown. The retaining flap  36  may be attached to the top material  24  the bottom material  22  by retaining seams  40 . 
     The container  10  is equipped with a drain  42 . The drain  42  is useful in allowing effluent accumulating in the container  10  be drained into an appropriate container or disposal system. In the embodiment shown in  FIG. 3 , the drain  42  is located in the bottom sheet  22  at the closed end  30  near a junction between two seams  24  that form an obtuse angle. 
       FIG. 4  is a cross-sectional view of the container  10  shown in  FIG. 3 . Starting toward the top of  FIG. 4 , the seam  24  at the closed end  30  connecting the top material  20  and the bottom material  22  is shown. The drain  42  located in the bottom sheet  22  is illustrated. Both the cap  46  and the spigot  48  are shown. In some embodiments, the cap  46  attaches to the spigot  48  by threads. If needed, a gasket may be used to help seal the cap  46  to the spigot  48 . When the container  10  is in use, the cap  46  may be removed and replaced by a hose or other conduit. 
     The loose ends  38  for each of the retained flaps  36  can be seen. The loose ends  38  may provide reinforcement to the container  10 . The retaining flaps  36  are attached by retaining seams  40  located both before and after the liner  34  thereby trapping the liner  34  between the retaining seams  40 , the retaining flaps  36  and the top  20  and bottom  22  sheets. 
     The strap loop retaining seams  44  are shown attaching strap loop  32  to the container  10 . The strap  16  residing in the strap loop  32  is also shown. The strap loop retaining seams  44  are formed of material  18  folded back on itself. The loops  28  are also shown. The loops  28  are formed of material  18  looped back on itself, and attached to the container  10  by retaining seam  50 . 
       FIG. 5  is a top view of a buckle  26  in a closed position in accordance with an embodiment.  FIG. 6  is a top view of the buckle  26  in an open position. With reference to both  FIGS. 5 and 6 , the straps  16  are shown attached to the buckle  26  and the strap ends  54  are shown.
