A containment device for sealing and protecting containers of biological materials. The device comprises a resilient cushion of aqueous fluid sorbent material having a plurality of openings. Each opening is adapted for receiving a respective container of biological material, and the openings are arranged such that each opening is surrounded by sufficient sorbent material to sorb leakage of biological material from its respective container if the container and/or if any additional containers break. The device also includes a case of aqueous fluid resistant material for receiving and enveloping the fluid sorbent material. The case includes two generally stiff-flexible portions having parts adapted for complementary interengagement and adapted to receive means for sealing the portions together to form an air and fluid tight package.

Containment device for biological materials

New molded fibrous filtration face masks that are highly resilient and shape-retaining are provided using one or more molded fibrous shaping layers, with a fibrous filtration layer disposed on one side of or between the molded fibrous shaping layers; the molded fibrous shaping layers having a total basis weight of at least 150 g/m2, and at least one of the fibrous shaping layers having an average density over the central area of the face mask of no greater than about 0.2 g/cc, such that at bends of the layer during deformation of the face mask the layer elastically deforms and tends to return to its original thickness and shape when the deforming pressure is removed.
