Title: Pressure relief valve for a flexible pouch
Inventor: JAMISON MARK D
IPC: B65D33/01
Filed: 2003-09-29
Abstract: The present invention provides a pressure relief valve (10) for a flexible pouch (12) which is integrated directly into the flexible pouch material. Th e valve permits excess of gas to dissipate through the valve mechanism but doe s not permit the reentry of air (hence oxygen) which maintains the food produc t fresh. The valve is integrated into the pouch material without implanting a fitment. The nature of the valve design results in the closing of the channe ls of the valve when gas is not discharging through the valve. A secondary purpose of the valve is to maintain the pressure in the pouch below an amoun t that can bloat the pouch to the extent that the seals can rupture and permit oxygen penetration or spilling of the contents outside the pouch. A nitrogen cap is maintained in the pouch thereby ensuring freshness of the product stored in the pouch.
