• a first cylindrically shaped sleeve portion adjoining the shoulder and including first walls extending into the neck and spaced from the outer walls to form an annular cavity therebetween, said first walls including a threaded interior periphery;
• a shelf provided in the inner periphery of the walls;
• a second cylindrically shaped sleeve portion including second walls adjoining the shelf and extending from the shelf into the neck, said second portion including a base;
• an orifice provided in the base;
• a splash plate adapted to be seated on the shelf, said plate configured to permit air to pass between the orifice and the first walls;
• a hollow cylindrically shaped adapter having first and second threaded portions, the adapter being sized to allow its first threaded portion to be threadably secured to the threaded interior periphery of the first sleeve portion, and
• a breather cap adapted to be threadably secured to the adapter, said cap having an orifice therethrough and a seat for securing a removable breather element.
