Abstract

An article for depositing a hot wax substance on a substrate in a desired pattern and which article includes a bowl having a reservoir for retaining the hot wax substance in a relatively liquid state. A spout extends outwardly from the housing and has a capillary tube connected to the spout and extending into the reservoir and terminating near the bottom wall of the reservoir. Moreover, this capillary tube has a relatively small diameter so that when the wax is in a heated state it will tend to rise in the tube by capillary action. When the reservoir is tipped so that the spout is pointed downwardly, the wax will flow through the spout and onto the substrate from the reservoir by means of a siphoning action. In a preferred aspect of the invention, a retaining tube extends through the reservoir in heat conductive relationship with the capillary tube. This retaining tube is designed to receive a heater element. In this way, the heater element actually applies heat to the wax in the reservoir retaining the same in the liquid state and also applies the heat to the capillary tube through heat conductivity. Several additional embodiments of the article are also disclosed and include a spatula in place of the spout and means for withdrawing the wax substance from a substrate after it has been applied. Moreover, the present invention provides a method of depositing and removing a hot wax substance from a substrate.
