The film holding plate has an active surface for receiving the film sheet, where the upper and lower tools cooperating to define a packaging chamber. The packaging assembly is open to receive the film sheet in a first operating condition and is hermetically closed in a second operating condition. The film holding plate has a lateral surface extending substantially perpendicular to a plane defined by the active surface, the film holding plate comprising ejectors arranged in the lateral surface for ejecting a stream of gas substantially parallel to said plane and substantially away from a center of the active surface.

A package that is suitable for packaging an article for collecting or administering a pharmaceutical active substance is disclosed. The package includes a first packaging component that includes a product-contacting sealant layer that includes a first ethylene vinyl alcohol copolymer. The package includes a second packaging component that includes a product-contacting sealant layer that includes a second ethylene vinyl alcohol copolymer. The ethylene content of the second ethylene vinyl alcohol copolymer is equal to or less than about 38 percent and the ethylene content of the first ethylene vinyl alcohol copolymer is greater than the ethylene content of the second ethylene vinyl alcohol copolymer.

A combination of a sonotrode and anvil, includes a sonotrode/anvil surface and a first row of sonotrode/anvil welding contact elements. The first/second series of each of the sonotrode/anvil welding contact element of a first row includes a first/second adapted lateral surface that joins at least one part of the first/second plateau surface with at least one part of the sonotrode/anvil surface side. The first/second adapted lateral surface includes a first/second curved surface positioned between the first/second plateau surface and the first/second substantially straight surface. The first/second curved surface has a convex outward arch. The welding contact element is positioned in relation to the anvil welding contact element such that the sonotrode welding contact element is positioned during welding next to the anvil welding contact element and is provided to form at least one part of a weld seam.

A flexible container is provided. The flexible container includes four panels. The four panels form (i) a body portion; (ii) a neck portion, and a flare portion that extends from the neck portion; (iii) a tapered transition portion between the body portion and the neck portion; and (iv) the neck portion has a reduced width. The flare portion has an expanded end. The width of the flare portion gradually increases from the neck portion to the expanded end.

The invention relates to a pressure unit (1) for sealing a package (2) for a food product, comprising a conveyor (3) for transporting the package (2) through the pressure unit (1) in a travelling direction (d), a first rotatable pressure roller (11) and a first rotatable anvil roller (21). The first pressure roller (11) is arranged opposite to the first anvil roller (21) to form a first nip (4) for receiving and rotationally engage with a portion (5) of the package, and arranged downstream of the first pressure roller (11) and the first anvil roller (21) in the travelling direction, a second rotatable pressure roller (12) and a second rotatable anvil roller (22). The second pressure roller (12) is arranged opposite to the second anvil roller (22) to form a second nip (6) for receiving and rotationally engage with the portion (5) of the package. The first anvil roller (21) and the second anvil roller (22), respectively, has a smooth rim surface (25). The first pressure roller (11) comprises a first bulge (15) extending annularly around its rim surface (18), the second pressure roller (12) comprises a second bulge (16) extending annularly around its rim surface (19), and the first bulge (15) is offset in relation to the second bulge (16) in an axial direction (7) of said first pressure roller (11) and the second pressure roller (12).

Provided is a production method for a freshness-keeping bag capable of reducing the inflow of oxygen from the outside of the bag to a very low level, and thereby keeping the freshness of a content thereof for a long period of time. The present invention provides a method for producing a freshness-keeping bag formed of a film, wherein the freshness-keeping bag has a band-shaped joining region in which two ends of the film are overlapped and joined together, the joining region comprising a plurality of joined parts in which the two ends of the film are joined together, and a non-joined part which is located between adjacent ones of the joined parts and in which the overlapped ends of the film are not joined together, the non-joined part composing a non-linear ventilation passage communicating between an internal space of the bag and the outside of the bag, the method comprising the step of forming the joined parts by ultrasonic welding, wherein the step of forming the joined parts includes continuously forming the joined parts in the film, while rotating a disk-shaped ultrasonic welding anvil with respect to the film, wherein the ultrasonic welding anvil has a plurality of protrusions formed on an outer periphery thereof continuously at given intervals and correspondingly to the configuration of the joined parts of the bag.

Embodiments are directed to a removable cap with a top hole and a seal with a heat induction closure for sealing an opening of a container. Advantageously, the cap and the seal do not need to be removed for a probe to access contents of the container, when used in a diagnostic analyzer, thereby eliminating operator steps of cap removal and seal peeling/perforation. Automated opening of the cap and seal combination is provided by puncturing the seal. The seal retains its opened shape required for unobstructed, non-contact probe access to contents of the container. The seal is comprised of three layers: a first polymer sealing layer capable of being heat-sealed to a container; an aluminum foil layer on top of the first polymer sealing layer, configured to heat seal the first layer by inductive heating; and a second polymer layer on top of the aluminum foil layer for protection.
