ABSTRACT:
A method is provided for forming in situ a seal for dispensing containers and the like of the type having a body with a reservoir, a dispenser with an applicator surface, and a cap detachably connected with the body, and selectively covering the dispenser applicator surface. The in situ method comprises providing a mandrel shaped geometrically similar to either the cap or the dispenser. The selected one of the cap and the dispenser is then assembled on the mandrel to form a closed cavity therebetween into which is injected a foamable liquid of the kind which expands when cured into a substantially closed cell construction. The liquid foam is cured in the cavity to the extent that the liquid foam expands to completely fill the cavity, and solidifies to create a seal formed in situ on the one of the cap and the dispenser. In use, the cured foam seal is disposed between the applicator surface of the dispenser and the cap, and prevents the product from inadvertently leaking from the reservoir.
