Abstract: An apparatus and method for detecting leaks at a fast rate in plastic bottles or similar containers wherein the bottles are secured in a multiplicity of open pocket members and arranged in a plurality of rows on a rotatable turret. A detecting gas is introduced into the bottles and they are subsequently moved to a detecting station where a detection means in the form of a mass spectrometer is activated by any gas leaking from the bottles. In a preferred manner, air is utilized to effect a sweeping action over the bottle exterior to move the detecting gas in the direction of the mass spectrometer. Air is also utilized to purge detecting gas from the pockets and air with vacuum to purge the bottles so that a rapid detecting system can be effected. The preferred gas used as the detecting media is helium and the bottles described are of the semirigid, plastic type which are used to contain sterile liquids.

Abstract: An automatic washing apparatus for containers which is capable of automatically and continuously washing a multiplicity of containers in a fast and efficient manner. The containers for which this particular washing apparatus is fabricated are of a semirigid type. They are composed of a plastic material and are elongated in configuration. The containers are intended to contain sterile liquids. The novel washing apparatus has a specially fabricated nozzle which can enter the plastic container and thoroughly wash it with a mixture of detergent, water and air. Suitable means are afforded to hold the semirigid containers in a stationary manner as well as to position them over a series of nozzles.
