Abstract

Abstract A rotary turret conveys containers through an arcuate path having an inner concave side and an outer convex side. Closures are supplied to a closure dispensing station located over a closure engaging station on the arcuate conveyor path by a line of movement generally in a plane tangential to the arcuate path at the closure engaging station. The closure entering the closure dispensing station is coerced into the position for proper alignment for the initial engagement of the closure by the container entering the closure engaging station. The closure being dispensed moves laterally outwardly toward the outer convex side of the arcuate path as the closure is being withdrawn from the closure dispensing station by the continued arcuate motion of the container, thereby maintaining the proper alignment of the closure to the container.

Claim 6
Dependent Claim 88 words
Apparatus in accordance with claim 1 wherein the width of said passageway at said closure dispensing station is equal to or slightly greater than the sum of the diameter of one of said closures and the distance the closure must move laterally outwardly to stay centered on the respective container as the container moves in said arcuate path from the point of initial engagement of the closure to the point where the closure is united with the container and is ready to be firmly seated on the container.
Claim 7
Dependent Claim 53 words
Apparatus in accordance with claim 5 wherein said closure coercing means is positioned to extend downwardly into said closure passageway at a point which is at a distance from said first wall of said passageway in the range of about 60 to about 95 percent of the diameter of one of said closures.
Claim 8
Dependent Claim 48 words
Apparatus in accordance with claim 6 wherein the distance between the center point of said arcuate path and the vertical axis of a container in said closure engaging station is in the range of about 1.5 to about 5 times the horizontal diameter of one of said containers.
