Abstract

The invention relates to a packaging tube for a pre-determined volume of a biological substance to be stored at a low temperature and to a system including same. The inventive packaging tube comprises a portion (2) for receiving the volume and an annular end portion (3) designed to be more easily crushed by pinching than the receiving portion (2) and to adopt a flattened position in which two lips (30) are in contact with one another. In addition, the annular end portion (3) is designed such that the lips (30) are secured to one another in order to form a seal (31) on the tube. The system includes at least one such tube and a jaw welding device designed to move the annular portion (3) into the flattened position and to weld the lips (30) to one another in order to form the seal (31).

IPC Classes  ?

• B65B 7/14 - Closing collapsible or resilient tubes, e.g. for tooth-paste, for lighter fuel
