Abstract

L'invention concerne une caisse de transport standard conçue pour inclure un ou plusieurs éléments de refroidissement auto-alimentés destinés à la conservation non-statique d'aliments réfrigérés. Le terme "standard" tel qu'il est utilisé ici relativement à des caisses de transport désigne une spécification ATA 300 Catégorie 2. Les caisses de transport sont parfois aussi appelées "unités de transport" ou "coffres ATA". Il s'agit de conteneur d'expédition spécialement construits pour protéger les instruments et le matériel de musique lorsqu'il doit être déplacé, et sont souvent manipulés sans précautions par le personnel en charge des bagages. La présente invention propose une solution plus pratique au problème de la fourniture d'un refroidissement pour la conservation des aliments, tout en équilibrant également la nécessité de refroidissement et le besoin de facilité de stockage et de transport, plus particulièrement en association avec un certain nombre d'autres caisses de transport transportant d'autres équipements ou produits.
