Abstract
A tip-shaping device for crayons is disclosed. The device includes a cylindrical lower section housing a disposable paper cup for receiving melted wax and a conically-shaped top section holding a heat-conductive member with a tapered internal cavity and a drain opening at the bottom of the cavity for draining melted wax into the paper cup. The heat-conductive member is heated by a ceramic heater connected to a source of electrical power.
Claims8
A device for shaping the end of a soft wax marker, comprising:
- a vertically oriented housing having a lower section and a removable top section, the top section having a central opening therein and the lower section being sized to receive an upwardly opening disposable receptacle therewithin;
- a heat-conductive member mounted in the top section, the heat-conductive member having a substantially vertically oriented, internal, conically shaped cavity tapered along its length, with the larger diameter of the cavity being toward the top of the top section and communicating with the opening in the top section;
- a relatively small opening in the heat-conductive member located at the bottom of the conically shaped cavity for draining melted wax and sized to permit the free gravity flow of the melted wax therethrough for removal of the melted wax from the cavity;
- an electric heater for heating the heatconductive member to a temperture sufficient to partially melt the wax marker for shaping the tip thereof;
- and
- means for positioning and removably holding the disposable receptacle within the lower section and beneath the heat-conductive member with the opening of the receptacle in registration with the opening located at the bottom of the conically shaped cavity for receiving melted wax dripping from the opening, the lower section having an open upper end for removal therethrough of the receptacle when the top section is removed from the lower section.

A device for shaping the end of a soft wax marker, comprising:
- a vertically oriented housing including a lower section having a base, sidewalls, an open top, and spaced, inwardly directed brackets around the inner periphery of the sidewall near the top;
- a conically shaped, removable top section having a central opening therein,
- a heat-conductive member positioned below the central opening,
- struts extending from the sidewalls of the conical top portion for supporting the heat-conductive member, and
- heater means surrounding the heat-conductive member, the heat-conductive member having (1) a vertically oriented, conically shaped internal cavity, with the larger diameter of the cone facing upward and communicating with the central opening in the top section and (2) a relatively small opening in the bottom of the conically shaped cavity for draining melted wax;
- a removable and disposable receptacle for melted wax supported in the lower section of the housing beneath the drain opening of the heat-conductive means by the inwardly directed brackets;
- an electrical cord for connecting the heater means to a source of electricity;
- and
- means extending down the sidewall of the lower section including spaced-apart, inwardly directed gripping fingers for retaining the electric cord in place and directing it down the sidewall and out through an opening in the lower section of the sidewall.
