Abstract
A flexible pouch is placed in a stack provided with two plates forming a protecting body to sandwich and constrain the flexible pouch. At opposite margin portions, the protecting body has slots cooperating with positioning members of an outer shell device belonging to the stack. Between the shell parts, the plates can move during filling of the pouch and the margin portions shrink inwardly in a protecting body plane. Some of the positioning members act as stoppers, in order to have lower clearance range for shrink strokes of the protecting body in a middle part thereof, as compared to a higher clearance range at respective longitudinal end parts of the two opposite margin portions. A higher constraining effect can be obtained in a center of the pouch, to limit maximum thickness of its content, which is of interest for managing freeze/thaw operations of biopharmaceutical materials contained in the pouch.
