Abstract: A package for transporting objects which are sterile or which are to be sterilized. The package has a box for accommodating objects, and a covering sheet made of a leak tight material which is fastened to the box so as to seal the box in a leak tight manner. The package has a layer of a material forming a screen which is at least partial with respect to a decontamination gas and/or able to absorb a decontamination gas. The layer is sized to be placed in the box along the covering sheet such that the layer lies above the objects. A plate or grill is provided with projections and is shaped, depending on the position of the package, to allow unrestricted diffusion of the sterilization gas over the objects, and to restrict or prevent diffusion of the decontamination gas over these same objects.

Abstract: A packaging having a box, and a cover sheet made of a material that is not permeable to decontamination gas. The cover sheet has a window closed by a piece of selectively impervious material. A flexible piece of a material that is not permeable to a decontamination gas is fixed to the cover sheet by at least one of its edges and has a free part which is able to move between a diffusion position and a non-diffusion position.

Abstract: This packaging (1) comprises a box (3), a cover sheet (4) made of a material that is not permeable to a decontamination gas, comprising a window closed by a piece of selectively impervious material. The packaging further comprises a flexible piece (8) of a material that is not permeable to a decontamination gas, this piece being fixed to the cover sheet (4) by at least one of its edges (15) and comprising a free part (16), the free part (16) of said piece being able to move between a diffusion position and a non-diffusion position.

Abstract: This package (1) comprises a box (3) intended to accommodate objects (2) which are sterile and a covering sheet (4) made of a selectively leaktight material, fastened to the box (3) so as to seal the latter in a leaktight manner. This package (1) comprises one layer (6) of a material forming a screen which is at least partial with respect to a decontamination gas and/or able to absorb a decontamination gas, this layer (6) having a shape and dimensions such that it can be placed in the box (3) along the covering sheet (4) and that it lies above the objects (2) and at least a plate or a grill (20) provided with projections (21), shaped in order, in a diffusion position, to allow unrestricted diffusion of the sterilization gas over the objects (2), and, in a nondiffisuion position, to restrict or prevent diffusion of the decontamination gas over these same objects (2).
