A one-way air outlet channel is disposed inside a vacuum compression bag. The one-way air outlet channel includes an air inlet opening, a horizontal air channel, inclined air channel and vertical air channel and an air outlet opening in communication with one another in sequence. One end of the horizontal air channel is the air inlet opening in communication with a space inside the bag body, and the other end of the horizontal air channel is in communication with the inclined air channel. A bottom end of the vertical air channel is in communication with the air outlet opening, and a top end is in communication with the inclined air channel, such that at least two corner points are formed, at a location where the horizontal air channel connects the inclined air channel and at a location where the inclined air channel connects the vertical air channel.

The invention is directed to a one-way valve for a flexible package which comprises a first film layer having at least one first cut line and a second film layer having at least one second cut line, wherein the lines are offset from one another. An adhesive layer is disposed between the film layers. The film layers and the adhesive layer define a valve area wherein the first film layer and the second film layer are not permanently adhered to each other. The second cut line fluidly connects the interior of the flexible package to the valve area and the first cut line fluidly connects the valve area to the ambient atmosphere surrounding the flexible package. The adhesive pattern within the valve area creates a gas flow channel from the second cut line toward the first cut line.

Methods of making vents in containers made from flexible materials, including forming vent openings in a first flexible material, forming vent stand-offs on a second flexible material, and combining the flexible materials to form a vent passage for the flexible container.

A flexible, sterilizable pouch includes a first gas-impermeable web, a second gas-permeable web, and the third gas-impermeable web. The webs are arranged and sealed to form a cavity portion of the pouch and a header portion of the pouch. The header portion of the pouch is gas-permeable through the second gas-permeable web. The cavity portion of the pouch is configured to hold a medical device for sterilization and is configured to be sealed from the header portion after sterilization, thereby making the cavity portion gas-impermeable. The header is also configured to be removed from the pouch, leaving the cavity portion.

To suppress damage such as the formation of holes and wrinkles in laminated bodies constituting a bag. A bag having a storage section includes: laminated bodies that include a sealant film positioned on an inner surface of the bag and at least one plastic film positioned on an outer surface side of the sealant film; and a seal section where inner surfaces of one pair of laminated bodies are joined together. The seal section has an outer edge seal part that is positioned along an outer edge of the bag, and a steam-releasing seal part that is positioned closer to a center point side of the storage section than the outer edge seal part and peels off due to an increase in pressure in the storage section. The steam-releasing seal part peels off when the pressure in the storage section is 130 kPa or lower.

The invention is an integrally blow-moulded bag-in-container obtainable by blow-moulding an injection moulded multi-layer preform. The bag-in-container includes an inner layer forming the bag and an outer layer forming the container, and a single opening, the mouth, fluidly connecting the volume defined by the bag to the atmosphere. The container further includes at least one interface vent fluidly connecting the interface between inner and outer layers to the atmosphere, wherein the bag is anchored to the outer layer at at least one point remote from the single opening and interface vent. The invention also relates to a process and a mould for the production of the blow-moulded bag-in-container.

A sterilizable pouch includes at least one sheet, wherein outer peripheral edges of the at least one sheet are sealed together to define a pouch having an interior space for receiving an article therein. A first releasable seam spans between a first peripheral edge of the at least one sheet to a second, opposite, peripheral edge of the at least one sheet, the first releasable seam dividing the at least one sheet into a first sheet part and a second sheet part. A second releasable seam and a third releasable seam each substantially span from a third peripheral edge of the at least one sheet to a fourth, opposite, peripheral edge of the at least one sheet and along the first peripheral edge and the second peripheral edge, respectively. The second and third releasable seams are arranged generally perpendicular to the first releasable seam, where the first, second and third releasable seams enable the pouch to be completely opened such that a device can be removed from the pouch without the device contacting non-sterile portions of the pouch.
