Bottle with Sealing Insert

Abstract

A hazardous materials containment bottle provides greater sealing against the environment by the combination of a funnel-like cone-shaped insert with a lid which includes a downward projecting stopper that mates with an aperture in the center of the insert. A second sealing point is provided by a circular rim at the top of the insert which is compressed between a ledge along the top of the bottle sidewall and the underside of the lid. A third sealing point is provided by a gasket between the outer circumference of the lid and a flange around the mouth of the bottle.

1 . A bottle, comprising:
 a body having an internal containment space and an open mouth at the top;   an insert tightly fitted within the mouth of the bottle along an internal sidewall of the body and extending from a circumferential top edge convergently downward to a central aperture; and   a lid having an underside including a downward projecting stopper in the center, a fingertip of said stopper being in seating relation with said insert aperture along an outside circumference of said fingertip whereby said containment space is closed thereby when the lid is in a closed position over the mouth of the bottle.   
     
     
         2 . The bottle of  claim 1  wherein said mouth is encircled by a radially outwardly extending flange of said body. 
     
     
         3 . The bottle of  claim 2  further including a clamp substantially encircling said flange and longitudinally compressing said lid against said body. 
     
     
         4 . The bottle of  claim 3  further including a rim extending upwardly from the top edge of said insert, said rim being compressed between an annular ledge along the inside wall of said containment space and the underside of said lid. 
     
     
         5 . The bottle of  claim 1  wherein the dimension of said insert aperture is selected such that the surface tension of a fluid within said containment space forms a bubble over the aperture when said bottle is inverted preventing the escape of said fluid through said insert aperture. 
     
     
         6 . The bottle of  claim 1  wherein said bottle is composed of stainless steel. 
     
     
         7 . The bottle of  claim 1  wherein said insert is composed of silicon. 
     
     
         8 . The bottle of  claim 1  wherein said insert is substantially cone-shaped in its free state that is dimensioned such that the sides of the insert bulge outwardly by the fitment of said insert within an annular recess along the internal side wall of said containment space. 
     
     
         9 . The bottle of  claim 1  wherein said stopper is unitary with said lid. 
     
     
         10 . A bottle, comprising:
 a body having an internal containment space and an open mouth at the top;   a substantially conical insert tightly fitted within the mouth of the bottle and extending from internal sidewalls of the body convergently downward to a spreadable slit at the bottom of the insert; and   a lid having an underside including a downward projecting stopper in the center, a fingertip of said stopper being in seating relation with said insert slit along an outside circumference of said fingertip whereby said containment space is closed thereby when the lid is in a closed position on the bottle.
