Double packaging for object intended to remain sterile

A double packaging structure for an object, comprising:

• a hollow external container extending generally along a longitudinal axis and comprising a closed first end, an open second end and walls connecting the first and the second end, the second end configured to be closed by a closure system;
• and
• an internal container disposed inside the external container, the internal container including a hollow body and a cap, the hollow body configured to receive the object therein;
• and
• wherein the external container comprises a membrane closing the closed first end of the hollow external container, the membrane configured to deform responsive to application of pressure to the membrane, the membrane having an outer face and an inner face and configured such that pressure applied to the outer face of the membrane along the longitudinal axis pushes the inner face of the membrane against the internal container and causes the internal container to exit the external container at the second end of the external container, in the absence of the closure system;
• and
• wherein the cap of the internal container is configured to accommodate an object holder intended to fix the object securely inside the body.
