A method of making a pressurized packaged liquid beverage including filling a container including a one-way valve with a liquid mixture including a base liquid and a gum; sealing the container; introducing a volume of gas through the one-way valve after sealing the container; and agitating the container. When the container is opened, the liquid mixture increases in volume and separates into a liquid phase and a drinkable foam phase, which may persist for an extended period of time. The base liquid includes milk, coffee, fruit juice, or mixtures thereof.

Providing a packaging machine and a sealing method in the packaging machine both of which can reliably seal a packaging bag in a good-looking finish without forming large bubbles on a seal inner surface of a bag mouth of the packaging bag and/or creases on a seal part. A packaging machine includes a seal part preheating station for preheating a seal part of a packaging bag after the packaging bag has been filled with an article and steam deaeration has been carried out, a decorative seal applying station provided downstream of the seal part preheating station for applying a decorative seal to a part of the packaging bag above the seal part and an ultrasonic seal applying station provided downstream of the decorative seal applying station for applying an ultrasonic seal to a part of the packaging bag A below the seal part.

A packaging system includes a first sealer and a gas flusher. The first sealer creates a first seal in packaging material along a direction of travel of the packaging material, thereby forming a packaging loop. The gas flusher flushes ambient air from the packaging loop and includes a mechanically retractable lance that can be selectively repositioned relative to the first sealer. When the mechanically retractable lance is in an operative position, the mechanically retractable lance projects into the packaging loop, with a gas flowing through the mechanically retractable lance into the packaging loop.

A reusable packaging device that in a use state is a rhomboid outer structure with an internal inflatable and reusable vessel that surrounds and protects a payload, that can be converted into a storage state by deflating the vessel and folding the outer structure flat in order that it may be stacked.

A vacuum sealer for vacuum packing products in plastic vacuum bags includes a sealing bar and a lift mechanism configured to raise and lower the sealing bar. In the raised position, the sealing bar is configured to engage and compress the vacuum bag against a compression bar. The vacuum sealer include a vacuum pump that is operated to draw a vacuum in the vacuum bag. The sealing bar includes a heating element that is configured to heat the sealing bar when energized. Once the vacuum is drawn in the vacuum bag, the sealing bar is heated and the heat is applied to the vacuum bag, which seals closed the vacuum bag with the product vacuum packed therein. The lifting mechanism lowers the sealing bar to release the vacuum packed product. The vacuum sealer includes a cooling chamber into which the sealing bar is moved when lowered by the lift mechanism. A cooling fan directs convection air through the cooling chamber and over the sealing bar to cool the sealing bar.
