CA 2130361
A body warmer for use in footwear is disclosed which is prevented from slipping in footwear and is capable of warming a desired portion accurately, and which includes an exothermic composition capable of generating heat in the presence of air, an air-permeable bag accommodating the composition, and an air-tight bag sealingly enveloping the air-permeable bag, the air- permeable bag being formed with a non-slip layer in at least a portion thereof.
Une composition produisant de la chaleur en présence d'air est renfermée dans un sac de stockage perméable aux gaz, et ce sac de stockage est fermé hermétiquement dans un sac étanche à l'air, une couche anti-glissement étant appliquée sur au moins une partie du sac de stockage. On empêche ainsi le sac de stockage de glisser dans la chaussure, et une partie désirée du pied de l'utilisateur peut être chauffée.
