Abstract: A nozzle member for an automatic washing apparatus for containers which nozzles are capable of washing containers in a fast and efficient manner. The containers for which this particular nozzle is fabricated are of the semirigid type and are composed of a plastic material. They are elongated in configuration and are intended to contain sterile liquids. The nozzle is fabricated to enter the plastic container and thoroughly wash it with a mixture of detergent, water, and air. This is a continuation, of application Ser. No. 660,587 filed Feb. 23, 1976, now abandoned.

Abstract: A spin or friction welding apparatus which can accurately locate a container such as a semirigid plastic bottle with respect to an overcap which is to be frictionally welded to the bottle by means of a rotatable spindle member. In order to assure that the overcap is secured to the bottle neck when employing high production machinery utilizing a rotating spindle mechanism for frictionally engaging the cap on a stationary bottle, many tolerances must be compensated for in the dimensions of the cap, the size of the neck on the container, as well as the positioning of the cap in relation to the container. To compensate for these variables, a biasing means is provided in conjunction with the rotatable spindle member so as to effect a predetermined tension on the cap member when it engages the stationary container neck and is spun into frictional engagement with it.
