ABSTRACT:
This relates to a closure combination which includes the closure being formed with a sealant channel to which there is applied by spin lining a plastisol type compound sealant, or the like. It is preferred, from an economy standpoint, to utilize a minimal amount of the sealant while providing the necessary sealing surface between a container neck finish and the sealant. Since the sealant is applied by a spin lining process during which the closure is rapidly rotated, the sealant is thrown radially outwardly by centrifugal force. However, the viscosity of the sealant normally is such as to prevent it from being returned to a level-flat condition. It has been found that by modifying the sealant channel configuration, particularly the slope of the base wall thereof, depending upon the viscosity of the sealant, one can selectively obtain a uniform thickness sealant application or a flat top sealant application. Further, by sloping the end seal surface of the container to which the closure combination is to be applied, one can obtain extra beneficial results. It is also desirable to provide a dam arrangement for the sealant which permits return overflow of the sealant with the dam accommodating the overflowing sealant.
