ABSTRACT:
A vertical hollow plastic cylinder having a first outer diameter is open at an upper end and closed at a lower end is adapted to store fluid. A vertical hollow plastic member has upper and lower open ends and, as viewed in a horizontal plane has a circular cross section. The upper end of the member has a second outer diameter, the lower end of the member having a third outer diameter. The second diameter is equal to the first diameter and is larger than the third diameter. The member has an exposed inner surface having the general shape of a bowl and extending downwardly and inwardly from the upper end to the lower end of the member. The outer surface of the member has a first upper vertical section having the second diameter and a second lower vertical section having the third diameter. The first and second sections are interconnected by a horizontal shoulder. The second section is disposed within the upper end of the cylinder with the outer surface of the second section being flush with the inner surface of the cylinder. The upper end of the cylinder is flush with the inner surface of the cylinder, the upper end of the cylinder engaging and being sealed to the shoulder. A vertically elongated plastic element has an upper end disposed above the member and extends downwardly through the member into the cylinder. The element has a lower end disposed below the second section and has a vertical bore which extends upwardly from the lower end of the element to a point intermediate the ends of the element. Vertical bristles are secured in the bore and extend out of the element into the cylinder. A horizontal annular breakable seal is disposed between the element and the inner surface of the lower end of the member to seal the element to the member.
