Abstract
Abstract A housing for warming or heating a towelette containing a compartment, a heating element associated with the compartment, a plate for directing heat uniformly from the heating element to a towelette, insulative support for said towelette above the heat element and the plate, and a circuit for supplying power to the heating element. Power is provided by AC, with a switch for energizing the device and a thermostat for controlling the temperature. Towelettes warmed by the device are useful for refreshingly cleaning the hands, face or other parts of the body.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
167 words
A towelette heating device for heating towelettes comprising: (a) a top having a forward section including an indentation thereupon, a bottom and low lying side walls forming a housing; (b) a compartment within said housing and a partially or totally transparent cover means on said top of said housing to permit access to said compartment and view the towelettes therethrough, said cover hingedly attached at one end to said housing and proximate said indentation of said forward section at an opposite end of said housing to permit access to lift said cover; (c) a heating element cooperatively retained within said compartment; (d) heat-insulative means for supporting at least one towelette immediately above said heating element; (e) means for substantially uniformly directing heat from said heating elements onto said at least one towelette, said means cooperatively retained in said compartment between said heating element and said support means; and (f) circuit means adapted to supply power to said heating element and to be connected to a power source.
Claim 2
Dependent Claim
167 words
A towelette heating device for heating towelettes comprising: (a) a top having a forward section including an indentation thereupon, a bottom and low lying side walls forming a housing; (b) a compartment within said housing and a partially or totally transparent cover means on said top of said housing to permit access to said compartment and view the towelettes therethrough, said cover hingedly attached at one end to said housing and proximate said indentation of said forward section at an opposite end of said housing to permit access to lift said cover; (c) a heating element cooperatively retained within said compartment; (d) heat-insulative means for supporting at least one towelette immediately above said heating element; (e) means for substantially uniformly directing heat from said heating elements onto said at least one towelette, said means cooperatively retained in said compartment between said heating element and said support means; and (f) circuit means adapted to supply power to said heating element and to be connected to a power source.
