Flexible laminate structure with integrated one-way valve
10689160 · 2020-06-23 · ·

A flexible laminate for a package is described that includes an integrated one-way valve that allows gas generated within the package (e.g., carbon dioxide outgas) to be released to the external environment, while at the same time preventing environmental elements from entering the package. The valve is defined by the layers that form the flexible laminate, as opposed to being a separate structure that is attached to the flexible laminate. In particular, first and second cut lines are defined in a valve area of the first and second film layers of the flexible laminate structure in an offset manner. Oil is pattern-applied to one or both film layers in the valve area, and an opposing surface of one or both of the film layers further includes a surface treatment that decreases the amount of surface energy between the film layers to allow the valve to open at the desired pressure.

An inflatable web (10) includes a top film (30) heat sealed to a bottom film (32) to define sealed regions (40) and non-sealed regions (214). The non-sealed regions include inflatable regions (216) that are inflatable through one or more inflation ports. The top film (30) may have a color that differs from the color of the bottom film (32) to create a visual contrast between the sealed regions (40) and the adjacent non-sealed regions (214) when the web is viewed from the top film side. The ratio of the surface area of the inflatable regions (216) to the total surface area of the inflatable web is at least 50% and at most 95%.

INFLATING STICK AND PROCESSING MACHINE

An inflating stick and a processing machine are provided. The inflating stick includes a body, a link rod, a cutter, and one or more inflating tubes. A front end of the body includes a guiding segment with a cone structure. A rear end of the body includes a packing segment of which an external diameter is greater than that of the guiding segment. The body includes a gas inlet formed on the packing segment. The body further includes an internal chamber allowing gas to flow into through the gas inlet and gas outlets formed on an outer wall of the body allowing gas to flow out. The link rod and the cutter are disposed in rear of the body. The inflating tube is connected to the gas inlet for supplying gas to the internal chamber, and the gas can flow out from the gas outlets to inflate the gas columns.

VALVE ASSEMBLY FOR BAGS

A present application relates to a valve assembly for use with a liquid container. The valve assembly includes a spout containing an opening to the liquid container, the spout being configured to form a liquid-tight seal with a housing. A sleeve extends through the housing toward the liquid container through the opening.
