  • Receiving a portable cooling storage device is performed as follows. First, the insulation plate 200 and the cooling storage unit 300 are separated from the body 100. All the storage objects and the coolant are removed from the storage space S2 of the cooling storage unit 300, and the auxiliary envelope 325 is extracted to the outside of the storage space S2 to remove contaminants or residues. Subsequently, the first side surface 113 is folded and folded based on the first fold line 113a. Accordingly, the first side surfaces 113 are sandwiched between the second side surfaces 115 to remove the internal space S1, and the first side surfaces and the second side surfaces are in close contact with each other.

  • the storage color 400 is particularly useful for leisure activities. When you go outdoors, many objects are included in the cold storage, but when you return home, in most cases the objects are consumed or arranged to return to the empty storage. At this time, as mentioned above, by storing in the storage color 400, it is also possible to increase the convenience in the outdoors.

It can prevent.
  • the auxiliary outer shell is fixed to only the upper end of the cooling storage unit in the storage space to easily remove foreign substances remaining in the cooling storage unit after use.

Abstract

L'invention porte sur un dispositif de stockage à froid portable qui est pliable. Le dispositif de stockage à froid comprend : un corps comprenant une unité de réception ayant une partie latérale qui peut être pliée avec une feuille de plancher le long d'une première ligne de pliage et qui comporte un isolateur thermique, et comprenant une unité de couvercle reliée à ladite partie latérale et scellant hermétiquement l'espace interne de ladite unité de réception vis-à-vis de l'extérieur ; une plaque d'isolation thermique disposée de façon détachable sur la feuille de plancher de ladite unité de réception, maintenant une partie de plancher de ladite unité de réception sous une forme constante, et comportant ledit isolateur thermique de façon à bloquer le transfert de chaleur à travers ladite partie de plancher ; et une partie de stockage à froid qui peut être pliée le long d'une seconde ligne de pliage, qui comprend un isolateur thermique auxiliaire qui peut être reçu de façon détachable dans l'unité de réception, qui est disposée sur ladite plaque d'isolation thermique, qui stocke un agent de refroidissement et des articles à stocker, et qui isole thermiquement ledit agent de refroidissement et les articles à stocker vis-à-vis de l'environnement de ceux-ci. Un stockage facile est amélioré par la réduction de l'espace requis pour le stockage.
