Hot Melt Dispensing Apparatus

This is a hot melt dispensing apparatus particularly adapted for the application of hot melt coatings to special configuration areas of electrical devices, to provide them with protection from hostile environments. The dispensing apparatus can be readily modified to accommodate various application needs.

The apparatus comprises basically reservoir 1 which can be of any shape adapted to fit the need. Applicator element 2 is closely fitted to the internal shape of reservoir 1. Aperture 3 of element 2 is shaped for the desired hot melt coverage of the article being protectively coated. Applicator element 2 is provided with two flat springs 4 which extend from the top surface of element 2.

In operation, hot melt in granular, pellet, stick, or liquid form is placed in reservoir 1. Reservoir 1 is heated by either external or internally contained heating coils, until the hot melt is in a molten state. Heat is continuously supplied to maintain the hot melt material in a molten state. When an article that is to be coated with hot melt material is placed in overlying position to aperture 3 and then forceably depressed, molten hot melt material rises through aperture 3 and is applied to the area of the article being coated. When the forces depressing applicator 2 are released, spring 4 engaging the sides of reservoir 1 will return the applicator to a normal position that causes the hot melt material flow to cease.
