Portable heat treatment system and refill unit therefor

Claim 2

A refill unit usable in conjunction with a heating shoe of a portable heat treatment system to provide heat therapy to a part of the human body; characterized in that said unit includes a heat conductive container having a base and peripheral walls extending upwardly from said base to define an interior compartment, a material for treating parts of the human body only partially filling the compartment, said material being in a solid state at room temperature and being adapted to be melted within the heating shoe for use in providing heat treatment therapy to a part of the human body, opposed peripheral walls of said container each including an upper bent edge defining a handle-retaining channel, and a pair of handle members, each of said members extending through opposed ends of a respective channel and having a section between the opposed ends adapted to be engaged for the purpose of transporting said refill unit, said section of each handle member being positionable within the interior compartment of the container and being dimensioned to be above the level of the body treating material when positioned within said interior compartment.

Claim 3

The refill unit of claim 1 characterized in that each handle includes a flexible chain and a plastic gripping member encircling said chain.

Claim 4

The refill unit of claim 2 characterized in that the chain is a metal ball chain and the plastic gripping member is a split plastic sleeve encircling the chain.

Claim 5

A refill unit usable in conjunction with a heating shoe of a portable heat treatment system to provide heat therapy to a part of the human body; characterized in that said unit includes a heat conductive container having a base and peripheral walls extending upwardly from said base to define an interior compartment, a material for treating parts of the human body only partially filling the compartment, said material being in a solid state at room temperature and being adapted to be melted within the heating shoe for use in providing heat therapy to a part of the human body, said peripheral walls including opposed side walls and opposed end walls, said opposed end walls being shorter than said opposed side walls for defining a substantially rectangular interior compartment, and upper edges of said opposed end walls each being rolled to provide a substantially cylindrical handle-retaining channel therein, a handle disposed adjacent each of the end walls of the container, each handle including a member extending through opposed ends of a respective cylindrical handle-retaining channel and being confined within said channel for preventing it from inadvertently separating from the container each member including a section between the opposed ends adapted to be engaged for the purpose of transporting said refill unit, said section of each member being positionable within the interior compartment of the container and being dimensioned to be above the level of the body treating material when positioned within said interior compartment.

Claim 6

A refill unit usable in conjunction with a heating shoe of a portable heat treatment system to provide heat therapy to a part of the human body; characterized in that said unit includes a heat conductive container having a base and peripheral walls extending upwardly from said base to define an interior compartment, a material for treating parts of the human body only partially filling the compartment, said material being in a solid state at room temperature and being adapted to be melted within the heating shoe for use in providing heat therapy to a part of the human body, said peripheral walls including opposed side walls and opposed end walls, said opposed end walls being shorter than said opposed side walls for defining a substantially rectangular interior compartment, and upper edges of said opposed end walls each being rolled to provide a substantially cylindrical handle-retaining channel therein, a handle disposed adjacent each of the end walls of the container, each handle including a member extending through opposed ends of a respective cylindrical handle-retaining channel and being confined within said channel for preventing it from inadvertently separating from the container each member including a section between the opposed ends adapted to be engaged for the purpose of transporting said refill unit, said section of each member being positionable within the interior compartment of the container and being dimensioned to be above the level of the body treating material when positioned within said interior compartment.

Claim 7

The refill unit of claim 4 characterized in that each handle includes a flexible chain and a plastic gripping member encircling said chain.

Claim 8

The refill unit of claim 5 characterized in that the chain is a metal ball chain and the plastic gripping member is a split plastic sleeve encircling the chain.

Claim 9

A portable heat treatment system including a portable heating shoe, a cover for said heating shoe, and a refill unit removable retained within said heating shoe, said refill unit including a heat conductive container having a base and peripheral walls extending upwardly from said base to define an interior compartment, a material for treating parts of the human body only partially filling the compartment, said material being in a solid state at room temperature and being adapted to be melted within the heating shoe for use in providing heat treatment therapy to a part of the human body, opposed peripheral walls of said container each including an upper bent edge defining a handle-retaining channel, and a handle member extending through opposed ends of each of said channels and having a section between the opposed ends adapted to be engaged for the purpose of transporting said refill unit, said section of each handle member being dimensioned to be above the level of the body treating material when disposed within the interior compartment of the container, each of said sections being disposed within the interior compartment of the container when said refill unit is within the heating shoe and the cover closes said shoe.

Claim 10

A portable heat treatment system including a portable heating shoe, a cover for said heating shoe, and a refill unit removable retained within said heating shoe, said refill unit including a heat conductive container having a base and peripheral walls extending upwardly from said base to define an interior compartment, a material for treating parts of the human body only partially filling the compartment, said material being in a solid state at room temperature and being adapted to be melted within the heating shoe for use in providing heat treatment therapy to a part of the human body, opposed peripheral walls of said container each including an upper bent edge defining a handle-retaining channel, and a handle member extending through opposed ends of each of said channels and having a section between the opposed ends adapted to be engaged for the purpose of transporting said refill unit, said section of each handle member being dimensioned to be above the level of the body treating material when disposed within the interior compartment of the container, each of said sections being disposed within the interior compartment of the container when said refill unit is within the heating shoe and the cover closes said shoe.
