On the other hand, if it is thicker than this range, it will be too thick and the strength will be too great to follow the contraction of the container body 30. In addition, the water vapor absorbed when left to cool after sterilization is not released sufficiently and remains in the non-woven sheet 21 and becomes insufficiently dried. Therefore, the medical supplies storage container 10 is grasped together with the non-woven sheet 21 and lifted.

Abstract

La présente invention concerne un récipient de stockage de produit médical selon lequel une étiquette apposée sur le récipient de stockage de produit médical ne peut pas plisser ou s'arracher, et les informations enregistrées sur l'étiquette peuvent être lues de manière fiable même lorsque l'étiquette est exposée à une atmosphère de vapeur à haute pression lors d'un traitement de stérilisation à la vapeur à haute pression. Selon l'invention, un récipient de stockage de produit médical (10) subit un traitement de stérilisation à la vapeur à haute pression, le récipient de stockage de produit médical (10) comportant : un corps (30) de récipient dans lequel un produit médical sélectionné parmi un dispositif médical et un produit pharmaceutique est stocké, le corps (30) de récipient comportant une partie de fond (31) au niveau d'une extrémité inférieure, une partie de paroi périphérique (32) contiguë à la périphérie de la partie de fond (31) et s'étendant vers une extrémité supérieure, une partie d'ouverture (33) entourée par l'extrémité supérieure de la partie de paroi périphérique (32), et une partie de rebord (34) s'étendant d'un bord périphérique de la partie d'ouverture (33) ; et un film protecteur (60) destiné à couvrir la partie d'ouverture (33) et à étancher le corps (30) de récipient, le film protecteur (60) étant apposé sur la partie de rebord (34). Au moyen d'une pâte utilisée en tant que constituant principal, on peut maintenir un état dans lequel une étiquette (20), obtenue par couchage d'une feuille non tissée continue (21) et d'une couche adhésive (22), est apposée sur une surface de paroi externe de la partie de paroi périphérique (32) par le biais de la couche adhésive (22) de façon à suivre la déformation du récipient (10).
