Abstract
Apparatus for dispensing heat meltable material from a container including a heated head adapted to engage the upper surface of the material within the container to melt the material immediately below the head. The head includes an inlet passage whereby melted liquid material may enter a reservoir defined in the head, and a dispensing pump includes an inlet communicating with the head reservoir whereby the melted material is pumped from the head reservoir for dispensing purposes. The head inlet passage includes flow control means for retaining melted material within the reservoir, and the head includes means for improving the heat exchanging characteristics between the head and the material confined within the reservoir.
Claims14
Apparatus for dispensing heat meltable material from a container including a support for a container of heat meltable material, a vertically movable frame mounted upon said support, means for vertically positioning said frame, dispensing means mounted upon said frame for vertical movement therewith, said dispensing means including a head adapted to enter said container of heat meltable material for engagement with the upper surface thereof, said head including a lower surface engaging the material upper surface, heating means heating said head to melt the heat meltable material adjacent said lower surface, a reservoir inlet defined in said head lower surface, vertically extending wall surfaces and a lower surface defined on said head defining a reservoir for receiving and holding melted material within said head, said inlet communicating with said reservoir, and a pump connected to said head having a pump inlet communicating with said reservoir.
A head for dispensing heat meltable material from a container comprising, in combination, a body of heat conducting material having a base region, a circular wall periphery, and a lower surface, said base region and wall periphery defining a reservoir for receiving and holding melted material, within said body, a reservoir inlet passage defined in said body intersecting said lower surface and communicating with said reservoir, heating means mounted in said body, and a pump mounted on said body having a pump inlet located within said reservoir adjacent said base region and an outlet for dispensing melted material.
