Abstract
A hot melt gasket or liner is applied to a portion of a manually operated dispenser having a closure cap for coupling the dispenser to a container. The material may contain a predetermined amount of gaseous fluid to form a foamed hot melt material having a predetermined density. After the material cools to room temperature, it forms an anti-slip gasket seal which, upon coupling the cap to the container neck, the hot melt material is compressed for restricting movement of the dispenser about the central axis of the container and for preventing formation of a leak path between the container rim surface and the dispenser.
