Abstract: A gantry style car wash assembly is disclosed. The car wash assembly has two opposing support pillars, a transverse gantry member, first and second opposed wall segments, and a brush mounted about a shaft. The transverse gantry member extends between the two opposing support pillars, and is moveable up and down relative to said two opposing support pillars. Each of the first and second opposed walls defines a portion of two opposing channels. The first and second removable wall segments are removably mountable above the first and second wall segments. Each wall segment includes a vertical extension channel that extends one of the two opposing channels substantially to said transverse gantry member. The brush extends between said first and second pillars, and that is mounted within said two opposing channels for upward and downward movement of said brush.

Abstract: A funnel for facilitating emptying of a liquid-filled container includes a receptacle. The receptacle is configured to support the liquid-filled container in a declined position with an opening of the container at or near a lowermost point of the container. The receptacle has an outlet for liquid. The funnel also includes a container shelf, adjacent to the receptacle, configured to support the liquid-filled container in an inclined position in which the container is inclined towards the receptacle. A tipping edge between the receptacle and a top of the container shelf is adapted to act as a fulcrum for tipping the container from the inclined position to the declined position. The receptacle may be formed within an insert that is removable from a base section of the funnel. A piercing element for piercing a protective seal on the opening may protrude inwardly into the receptacle on an angle.
