Patent

CA 2250471

This invention relates to a method of manufacturing heat cells which are based on a specific iron oxidation chemistry and having specific physical dimensions and fill characteristics. This method uses direct compaction of powdered ingredients into granules, pellets, tablets, slugs and/or the like. These heat cells, which can be incorporated into disposable body wraps, provide a controlled and sustained temperature for consistent, convenient, and comfortable heat application for treating temporary or chronic pain. This invention also relates to said exothermic compositions incorporated into said heat cells.

L'invention concerne un procédé de fabrication de cellules chauffantes réalisées par une chimie de l'oxydation du fer spécifique et pourvues de caractéristiques physiques spécifiques de dimension et de remplissage. Ce procédé consiste à effectuer un compactage par voie sèche d'ingrédients en poudre pour obtenir des granules, des pastilles, des cachets, des comprimés ou des produits similaires. Ces cellules chauffantes, qui peuvent être insérées dans des conditionnements jetables à usage corporel, produisent une température régulée et soutenue pour une application de chaleur régulière, pratique et douce dans le cadre d'un traitement d'une douleur temporaire ou chronique. Cette invention se rapporte également aux dites compositions exothermiques incorporées aux dites cellules chauffantes.
