摘要： This relates to the forming of a seal between a container and a top element, such as a fitment, wherein the seal is subjected to a high top loading of a nature wherein conventional gasket materials, such as plastisols, will unduly flow and result in leakage. In lieu of the conventional gasket material, a hot melt material is utilized with the hot melt material being in a flowable state when the fitment is applied to the container and held in place by a mechanical interlock between the fitment and the container so as to cause an extrusion and flowing of certain of the hot melt material wherein the hot melt material functions both as a gasket and as a support to eliminate or restrain movement between the fitment and the container due to top loading. A special dispensing head is also provided for applying a controlled volume of hot melt material to each fitment in a preselected pattern.
