Packaging valve closure system and method thereof

Abstract

The present invention relates to a package. The package comprises at least one valve or closure arranged at an access opening of the package. A method of forming and dispensing contents from a flexible package is also disclosed. A holder seal may be selectively applied to seal the closure to the package, control pressure within the closure, and define a product flow path for the user to dispense product under sufficient pressure.

Description

technical field [0001] The present invention relates generally to a flexible package, and in particular to a package and methods of making and using the package with a sealing valve closure. Background technique [0002] Known flexible packages for containing liquids are usually single-use packages, or include fittings with added screw or snap lids for multiple-use products. Single-use packages are less expensive, however once the package has been opened all product must be used or transferred to another container as there is no way to close the package again. Because not all products must be used or transferred to another container once initially opened, multiple-use packages that include fittings or other closure mechanisms are beneficial, however they can be very expensive (e.g., manufacturing and material costs) And they require two hands to operate. [0003] Some packages use leak-proof or leak-proof zippers to reclose the package. Zippers of various designs and push...

Problems solved by technology

However, both zippers and the interlocking members of the push-to-close mechanism are also susceptible to fluid leakage, and they may undergo plastic deformation after repeated use, which adversely affects the mechanism's ability to properly seal fluid within the package.

Also, zippers and push-to-close mechanisms may not be suitable for gas tight

As a result, the contents of the package are susceptible to oxidation and other airborne issues such as the release of odors
