A paraffin bath apparatus for melting paraffin used in therapeutic applications is disclosed. The paraffin bath apparatus comprises a housing having a base, a sidewall and upper opening. An inner tub is formed of a temperature resistant polymeric material is a generally cup shaped member having a bottom wall, an upstanding wall and an open top. The inner tub is received within the upper opening of the housing with the bottom wall of the inner tub overlying the base of the housing. The heating element is located between the inner tub and the housing for providing heat to the inner tub sufficient to melt the paraffin but below the temperature that would adversely affect the polymeric material forming inner tub. A thermostatic sensor is disposed between the inner tub and the housing and is electrically connected to the heating element to control the heat provided to the inner tub. A temperature indicating element may be provided in the inner tub and placed in contact with paraffin melted in the inner tub. The temperature indicating element provides a visual indication that the paraffin in the tub is within a predetermined temperature range and is visible through the melted paraffin.

DETAILED DESCRIPTION What is claimed is: 1.
A paraffin bath apparatus for melting paraffin comprising: a tub being generally cup shaped and having a bottom wall and an open top; paraffin being provided in the tub; and a polymeric temperature indicating element that changes color when a predetermined temperature is reached, the temperature indicating element is affixed to the paraffin bath apparatus and placed in contact with paraffin in the tub, the temperature indicating element providing a visual indication that the paraffin in the tub is within a predetermined temperature range.
2.
The paraffin bath apparatus of claim 1 wherein temperature indicating element is visible through the paraffin after the paraffin is melted.
3.
The paraffin bath apparatus of claim 1 further comprising the temperature indicating element being secured to the inside of the tub.

Description:
TECHNICAL FIELD The present invention relates to a therapeutic paraffin bath appliance.
BACKGROUND ART Paraffin baths are used in therapeutic procedures, particularly procedures relating to the treatment of hand and foot treatments for arthritic and dermatologic conditions.
In the treatment of arthritis or for moisturizing skin a person may be directed to place their hand or foot in a paraffin bath.
In a paraffin bath, solid paraffin is heated to its melting point.
The person may remove their hand or foot from the bath leaving a coating of paraffin applied to their skin.
This procedure can relieve arthritic pain.
This procedure may also be used for moisturizing the skin on a person's hand or foot.
Paraffin baths are normally provided with a metallic inner tub that is received in an outer housing with heating elements attached to or located adjacent the metallic inner tub.
Paraffin baths having a metallic inner tub are relatively costly to manufacture which adds to the ultimate cost to consumers of such units.
An important aspect of paraffin bath appliances is the heating control.
some prior art paraffin baths have been provided with a costly electronic controller
