Reusable seal for sewage basins

Abstract

A sewage basin arrangement is provided having a flange surface about the opening of the basin, a continuous groove formed in that flange surface which is spaced apart from the fastener apertures and disposed between those apertures and the opening, and a length of compressible sealing tape mounted within the groove and protruding in part from the groove. The tape is secured to the groove by an adhesive disposed within the groove. The ends of the tape laterally overlap within the groove.

What is claimed is:  
     
         1 . Sewage basin arrangements comprising: 
 a basin having an opening to the interior of the basin,    a lid to cover the opening,    a rim formed on the basin about the opening,    a plurality of fasteners mounted to the rim and engagable with the lid,    a sealing assembly mounted between the rim and the lid,    the sealing assembly being disposed inwardly of the fasteners toward the opening,    the sealing assembly including a length of compressible material, mounted within a groove formed in the rim, with a portion thereof protruding out of the groove and toward the lid, and    the depth of the groove and the compression material being selected so as to avoid compression set then the lid is secured against the compression material to cover the opening.    
     
     
         2 . The arrangements according to  claim 1  wherein the length of compressible material is formed as a tape and an adhesive is provided to maintain tape contact with the groove, that adhesive being disposed so as to avoid contact with the lid when the lid is secured against the compressible material to cover the opening.  
     
     
         3 . The arrangements according to  claim 2  wherein the ends of the tape avoid creating a localized elevation of the tape toward the lid.  
     
     
         4 . Sewage basin arrangements comprising: 
 a basin having a solid body surrounding an interior region and having an opening in the solid body which provides access to the interior region,    a lid dimensioned so as to at least cover the opening,    a rim formed on the basin about the circumference of the opening and providing a flange surface about that circumference,    a plurality of apertures spaced about the flange surface for receiving fasteners to secure the lid to the rim,    a sealing assembly mounted between the flange surface and the lid to provide a fluid tight seal between the flange surface and the lid,    the sealing assembly including: 
 a groove mounted in the flange surface, the groove being formed between the apertures and the opening and spaced apart from the apertures, and  
 a length of compressible tape having a first end and a second end and mounted so as to rest within the groove and protrude at least in part from the groove and toward the lid.  
   
     
     
         5 . The arrangements according to  claim 4  wherein the tape has an adhesive on one side to retain the tape within the groove.  
     
     
         6 . The arrangements according to  claim 5  wherein the adhesive is placed upon the tape and the tape is mounted within the groove and the groove is dimensioned so as to prevent contact between the adhesive and the lid when the lid is secured to the basin.  
     
     
         7 . The arrangements according to  claim 4  wherein the ends of the tape laterally overlap within the groove.
