46948295, Sep 22, 1987

Filed:

Jan 9, 1986

Appl. No.:

6/817901

Inventors:

Ruth E. Frye - Lindsay OK

International Classification:

A61F 708
A61F 710

US Classification:

128399

Abstract:

A therapeutic stuffed toy according to the present invention comprises an outer stuffed fabric member, such as a "teddy bear," having an interior pocket containing a hermetically sealed container of a non-toxic liquid whose freezing point is below that of water and boiling point is above that of water. The container is removable from the pocket through an opening in the outer fabric member for the purpose of first preparing it for use by heating when the toy is to be used as a hot "compress", and cooling when the toy is to be used as a cold "compress". In another embodiment, the thermal material is in the form of salt dampened with propylene glycol or water.

Appl. No.:

7/499624

Inventors:

Ruth E. Frye - Lindsay OK

International Classification:

C09K 500

US Classification:

252 70

Abstract:

An organic thermal reservoir material containing hydroxyethylcellulose compounded with propylene glycol yields a dry, solid core material. Best results are obtained in a formulation comprising about 4 parts by volume of hydroxyethylcellulose and about 3 parts by volume of propylene glycol. The resultant organic compound is non-toxic, solid, non-tacky, dry and moldable into a solid structural form.

Abstract:

An organic thermal reservoir padding material containing a hydroxyalkylcellulose compounded with an alkylene glycol yields a dry, consolidated core material. Best results are obtained in a formulation comprising about 4 parts by volume of hydroxyethylcellulose and about 3 parts by volume of propylene glycol. The resultant organic compound (Table I) is non-toxic, solid, nontacky, dry and moldable into a solid structural form. A freeflowing, unconsolidated thermal reservoir material is produced by mixing about 2 parts by volume hydroxyethylcellulose with about 1 part by volume propylene glycol and about 1/4 part by volume bicarbonate of soda.
