Abstract: An apparatus for dispensing liquid or slurried products, in particular detergents and rinse aids for industrial cleaning processes, typically but not exclusively dishwashing machines. Replaceable containers are fitted directly to a receptacle on the operative part of the machine and the liquid product is easily dispensed from the container into the machine without spillage or soilage of user's hands. The apparatus is characterized by self-sealing around a hollow penetrating device that can be inserted when in use, at the lowermost portion.

Abstract: The invention concerns an apparatus for and a method of treating a plurality of zones of a processing line with a liquid, the liquid comprising a treatment liquid and a carrier liquid, wherein the treatment liquid is introduced into pipes conveying the carrier liquid to each zone as discrete slugs, and wherein the volume of each slug is selectively variable or wherein each slug may be introduced into the pipes at a selectively variable frequency. Preferably the treatment liquid is applied to all zones from a single source, and the slugs, upon discharge at least at one zone, remain substantially concentrated. The invention particularly concerns the lubricating of conveyors as in bottling lines.
