A liner for use with a fluid dispensing vessel. The liner includes a flexible pouch defining an interior region and configured to be placed in a fluid dispensing vessel. The pouch includes a top end that is partially sealed and that includes a first opening. The pouch includes a fluid passageway defined by at least two sealed boundaries and that leads from the opening to the interior region. The pouch includes a bottom end that includes a second opening. The liner includes a fluid dispensing fitment connected to the pouch and configured to be in fluid communication with interior region via the second opening. When fluid is poured into the interior region of the pouch through the opening, it can be dispensed from the pouch through the fitment.

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.

In a plastic bag including a triangular flap which has a folded hypotenuse and an open hypotenuse, a flow path is formed by the folded hypotenuse or the open hypotenuse to discharge air or gas through the flow path.

A machine for making packages containing liquid or creamy products includes stations for punching/forming a first blank defining upper, lower and rear faces of the open package. A punching and creasing station forms a second blank defining first and second lateral faces of the package. The second blank has a notch for partial transversal separation between the first and second lateral faces. A station for assembling the first blank with the second blank for opening/closing the package with the notch of the two lateral faces, arranged in a “V”, to form an edge of the package. A transport unit is movable along a feed direction and configured to receive the package from the assembly station. A station opens the edge and fills the package with a dose of the product fed through the open notch. A station seals the notch.
