A process of producing a package for a product by heat-bonding through a heat sealable coating a first wall of porous spun bonded polyolefin material to a second and thicker wall of porous material, placing a product atop the first wall, draping a thermoformable film over the product, heating the film, drawing the film against the product and the first wall, and bonding the drawn film to the first wall during the drawing operation.
Packaging for packaging of products under a transparent film, a process for performing this packaging and a device for using this process. The packaging comprises a plate of cardboard or the like intended for supporting at least one product to be packaged, whose face receiving the product or products receives a coating of a layer of synthetic material, a first sheet of synthetic material for covering the upper face of the plate and the product or products resting on it. The first sheet is attached to the plate by being heated and partial vacuum being applied through the plate, and projects beyond the peripheral edge of the plate. A second sheet of synthetic material covers the lower face of the plate and is attached to the upper covering sheet by the peripheral edges of each sheet to one another beyond the edge of the plate. The packaging provides a tamperproof packaging making display of the packaged product possible.
A method and a device for moistening a porous medical material provide that the material is evacuated before it is moistened. The invention also covers a method of producing a porous medical material from bone particles that are compressed to a stable porous body. Said porous body is particularly suitable for being moistened in accordance with the method of the invention.
A method and a device for moistening a porous medical material (50) utilize evacuation of the material before moistening it with a liquid which is contained in a container (48) for communication with the material (50).
A moisture resistant package for storing and transporting sterile items, such as specimens of human or animal tissue, comprises an inner tray that fits within a moisture resistant outer tray. The inner tray has a cavity for storing the specimen. The specimen is enclosed within the cavity by a non-porous inner lid that is sealed to the inner tray by an adhesive to create a moisture and microbial contaminant resistant environment that prevents moisture uptake into the specimen. The inner tray is enclosed within a complementary shaped cavity of the outer tray by an outer lid sealed to the outer tray to complete the assembly of the package. Thereafter, the package is terminally sterilized (using gas or radiation) so that the inner tray can be introduced into a sterile environment when it is removed from the outer tray. In a preferred embodiment, the inner lid includes at least one through hole to reduce the pressure differential that may occur between the outer tray cavity and the inner tray cavity, which differential may otherwise case premature lifting and separation of the inner lid from the inner tray. In addition, the outer tray and the inner tray may be formed of a sheet of transparent thermoplastic material, such as glycerol modified polyethylene terephthalate so that the specimen can be viewed without opening the package. Preferably, the sheet of material for the inner tray and the outer tray is laminated with a film of moisture barrier material and is deep drawn into a three dimensional die, while substantially maintaining the moisture barrier integrity of the trays.
A package for a surgical device such as a stapler is described. The package includes a top portion, a bottom portion, sidewalls which define a cavity that receives the stapler, bearing surfaces to abut the stapler and a flexible cover. The package also includes a conformable member situated between the cover and the stapler which deforms about the stapler to hold the stapler relative to the package when the cover is attached to the top portion, and which is released from the stapler when the cover is removed from the top portion.
